1 00:00:04,160 --> 00:00:07,160 Speaker 1: Get in touch with technology with tech Stuff from how 2 00:00:07,240 --> 00:00:15,000 Speaker 1: stuff Works dot com. Hey there, and welcome to tech Stuff. 3 00:00:15,040 --> 00:00:18,880 Speaker 1: I am your host, senior writer Jonathan Strickland with how 4 00:00:18,960 --> 00:00:23,400 Speaker 1: stuff Works dot Com and on many episodes of tech Stuff, 5 00:00:23,400 --> 00:00:26,439 Speaker 1: I like to look at companies that are decades old, 6 00:00:26,560 --> 00:00:29,320 Speaker 1: or even more than a century old in some cases. 7 00:00:29,720 --> 00:00:31,960 Speaker 1: But this time I'm going to take a look at 8 00:00:31,960 --> 00:00:35,520 Speaker 1: a company that just turned ten not too long ago, 9 00:00:36,120 --> 00:00:40,080 Speaker 1: and I'm talking about Fitbit. And really I'm gonna focus 10 00:00:40,159 --> 00:00:43,280 Speaker 1: both on the company itself and the technology it creates. 11 00:00:43,479 --> 00:00:46,120 Speaker 1: So you're gonna get both kind of a history and 12 00:00:46,120 --> 00:00:48,960 Speaker 1: evolution of the company, but also how does that technology 13 00:00:49,000 --> 00:00:52,000 Speaker 1: actually work. It's kind of marrying two different styles of 14 00:00:52,000 --> 00:00:56,680 Speaker 1: tech stuff in one delicious tech stuff package of goodness. 15 00:00:56,920 --> 00:01:01,920 Speaker 1: So this story begins back in two thousand seven, and 16 00:01:02,040 --> 00:01:05,080 Speaker 1: that is when two guys, one named James Park and 17 00:01:05,160 --> 00:01:08,039 Speaker 1: one named Eric Friedman, decided that they were going to 18 00:01:08,440 --> 00:01:13,319 Speaker 1: launch a company with the intent to produce fitness trackers, 19 00:01:13,520 --> 00:01:17,480 Speaker 1: essentially a pedometer on steroids, something that could give lots 20 00:01:17,720 --> 00:01:22,840 Speaker 1: of feedback to a person who was interested in getting fit. 21 00:01:23,920 --> 00:01:27,280 Speaker 1: But to be fair, all stories really have more of 22 00:01:27,319 --> 00:01:29,920 Speaker 1: a preamble than that, right, it's not just hey, today, 23 00:01:29,920 --> 00:01:31,880 Speaker 1: we decided to make a company. You have to figure out, well, 24 00:01:31,959 --> 00:01:36,679 Speaker 1: what led up to that? Well, James Park attended Harvard. 25 00:01:36,680 --> 00:01:39,840 Speaker 1: He was studying computer science, but he dropped out. He 26 00:01:39,880 --> 00:01:43,759 Speaker 1: didn't actually graduate from Harvard, he didn't earn a degree there. 27 00:01:44,319 --> 00:01:48,279 Speaker 1: After dropping out, he worked for the company Morgan Stanley 28 00:01:48,480 --> 00:01:50,560 Speaker 1: and he worked there for about a year. And then 29 00:01:50,680 --> 00:01:54,520 Speaker 1: Eric Friedman, he was actually at Yale. He got a 30 00:01:54,600 --> 00:01:59,040 Speaker 1: graduate and postgraduate degrees actually from Yale. He was studying 31 00:01:59,080 --> 00:02:01,760 Speaker 1: computer science. They are, and the two of them co 32 00:02:02,000 --> 00:02:07,880 Speaker 1: founded a company called Epis Technologies, and I'm guessing you 33 00:02:07,960 --> 00:02:10,400 Speaker 1: probably never heard of it because it didn't last very long. 34 00:02:11,000 --> 00:02:14,799 Speaker 1: Their focus was to create products to facilitate business to 35 00:02:15,040 --> 00:02:20,840 Speaker 1: business transactions. So, in other words, um, your ordinary consumers 36 00:02:20,919 --> 00:02:23,400 Speaker 1: or customers would never really come into contact with this 37 00:02:23,440 --> 00:02:28,120 Speaker 1: particular company. It wasn't marketing stuff for the average consumer. 38 00:02:28,240 --> 00:02:31,280 Speaker 1: This was for big companies and the transactions they make 39 00:02:31,320 --> 00:02:34,840 Speaker 1: with each other. Very different world than just going to 40 00:02:35,120 --> 00:02:39,000 Speaker 1: a store and buying a product. Right. Venture capitalists invested 41 00:02:39,040 --> 00:02:42,680 Speaker 1: a couple of million dollars in this technology. However, the 42 00:02:42,760 --> 00:02:47,560 Speaker 1: company just never found its footing. It eventually failed and 43 00:02:47,680 --> 00:02:51,440 Speaker 1: Parks said that he felt that his inexperience in large 44 00:02:51,480 --> 00:02:56,079 Speaker 1: part contributed to that failure, but that the failure itself 45 00:02:56,200 --> 00:02:59,480 Speaker 1: served as a very valuable learning experience for him and 46 00:02:59,520 --> 00:03:02,440 Speaker 1: for Freedom, and that they were able to take that 47 00:03:02,720 --> 00:03:07,240 Speaker 1: negative experience and learn from it and attempt something new. 48 00:03:08,800 --> 00:03:11,560 Speaker 1: So there might have been some valuable but harsh lessons 49 00:03:11,680 --> 00:03:15,240 Speaker 1: learned at that point. Anyway, the two of them and 50 00:03:15,280 --> 00:03:18,960 Speaker 1: a couple of other alumni from a PSC Technologies decided 51 00:03:19,000 --> 00:03:22,720 Speaker 1: to go on an entirely different direction with a brand 52 00:03:22,720 --> 00:03:27,720 Speaker 1: new company. They created a new venture called wind Up Labs, 53 00:03:28,600 --> 00:03:32,160 Speaker 1: and this time they were taking aim at online photo 54 00:03:32,360 --> 00:03:38,120 Speaker 1: editing and sharing using peer to peer technology. So this 55 00:03:38,200 --> 00:03:42,440 Speaker 1: happened around two thousand two. UH. They got to work 56 00:03:42,600 --> 00:03:46,280 Speaker 1: developing the tools you would need to do editing work 57 00:03:46,600 --> 00:03:49,320 Speaker 1: online and to use this peer to peer technology to 58 00:03:49,360 --> 00:03:53,240 Speaker 1: facilitate it, and it was successful enough for larger companies 59 00:03:53,280 --> 00:03:55,000 Speaker 1: to actually take notice of them. And one of those 60 00:03:55,080 --> 00:03:59,920 Speaker 1: larger companies was c net. So you're probably familiar with SEEN. 61 00:04:00,120 --> 00:04:04,040 Speaker 1: They have a lot of different UH branches. The one 62 00:04:04,080 --> 00:04:08,400 Speaker 1: that I'm familiar with is their website with their reviews 63 00:04:08,640 --> 00:04:11,240 Speaker 1: and their technology news. I know a couple of people 64 00:04:11,240 --> 00:04:14,760 Speaker 1: who work there, but they also do other stuff as well, 65 00:04:15,400 --> 00:04:17,080 Speaker 1: and one of the things they wanted to invest in 66 00:04:17,160 --> 00:04:21,239 Speaker 1: was this photo editing suite, so they acquired wind Up Labs. 67 00:04:21,279 --> 00:04:23,840 Speaker 1: They actually made a bid and then took ownership of 68 00:04:23,839 --> 00:04:26,800 Speaker 1: the company, and both Park and Freedman went on to 69 00:04:27,040 --> 00:04:32,640 Speaker 1: work for c net uh, becoming heads of various departments 70 00:04:32,640 --> 00:04:35,839 Speaker 1: within c NEET, and they became further entrenched in the 71 00:04:35,839 --> 00:04:40,360 Speaker 1: world of technology. Flash forward to two thousand and six, 72 00:04:41,880 --> 00:04:45,120 Speaker 1: another big company released a brand new product that got 73 00:04:45,160 --> 00:04:48,080 Speaker 1: both Park and Freedman kind of excited, something that they 74 00:04:48,120 --> 00:04:51,039 Speaker 1: had not really seen before that they felt had a 75 00:04:51,040 --> 00:04:54,320 Speaker 1: lot of value. That company was a little company called Nintendo, 76 00:04:54,960 --> 00:04:59,520 Speaker 1: and the product was the Wei video game console. Really, 77 00:04:59,560 --> 00:05:02,680 Speaker 1: they were very interested in the Wei controllers, the Wei 78 00:05:02,880 --> 00:05:06,560 Speaker 1: motes because they had all these motion sensors in them. 79 00:05:06,640 --> 00:05:10,040 Speaker 1: We were now entering into an era where these motion 80 00:05:10,080 --> 00:05:14,359 Speaker 1: sensors were getting very small and relatively inexpensive, so you 81 00:05:14,360 --> 00:05:18,120 Speaker 1: could incorporate them into totally new types of technology. You know, 82 00:05:18,200 --> 00:05:21,360 Speaker 1: before they were larger, they were more expensive, they were 83 00:05:21,400 --> 00:05:23,119 Speaker 1: limited in what you can do with them. But now 84 00:05:23,839 --> 00:05:27,640 Speaker 1: because manufacturing processes had improved and you're looking at the 85 00:05:27,680 --> 00:05:31,560 Speaker 1: economies of scale. They were suddenly a component that you 86 00:05:31,560 --> 00:05:34,920 Speaker 1: could fit another stuff. And we started seeing this across 87 00:05:35,000 --> 00:05:38,840 Speaker 1: all sorts of different products, including smartphones. We started seeing 88 00:05:38,839 --> 00:05:44,080 Speaker 1: those kind of technologies incorporated there. Well. They thought that 89 00:05:44,160 --> 00:05:49,039 Speaker 1: this we mote motion sensor technology was really revolutionary. But 90 00:05:49,160 --> 00:05:51,200 Speaker 1: they thought, this is a home console. What if we 91 00:05:51,240 --> 00:05:54,760 Speaker 1: could take this capability and put it into a more 92 00:05:54,839 --> 00:06:00,120 Speaker 1: portable device, and maybe it has a different aim and 93 00:06:00,360 --> 00:06:04,200 Speaker 1: video games. And that got them thinking, and eventually they 94 00:06:04,240 --> 00:06:07,760 Speaker 1: came to this idea of a fitness tracker that now 95 00:06:07,800 --> 00:06:10,760 Speaker 1: that you could get accelerometers and other types of sensors 96 00:06:10,800 --> 00:06:14,760 Speaker 1: to a small enough form factor and make them cheap enough, 97 00:06:15,240 --> 00:06:18,400 Speaker 1: you could pair them with some microprocessors and have a 98 00:06:18,440 --> 00:06:23,760 Speaker 1: really robust activity tracker. So they decided that this would 99 00:06:23,800 --> 00:06:27,080 Speaker 1: leave pedometers in the dust. It would set a new market, 100 00:06:27,520 --> 00:06:30,240 Speaker 1: and they left c Net in two thousand seven to 101 00:06:30,320 --> 00:06:34,440 Speaker 1: form a new company and they called it Fitbit. Now 102 00:06:34,440 --> 00:06:36,719 Speaker 1: that when they made this company, they didn't have any 103 00:06:36,720 --> 00:06:39,680 Speaker 1: products to show off yet. They had not built anything, 104 00:06:39,720 --> 00:06:43,160 Speaker 1: they hadn't designed anything. They just had an idea. They 105 00:06:43,200 --> 00:06:46,080 Speaker 1: invested their own money, and they also had friends and 106 00:06:46,160 --> 00:06:50,160 Speaker 1: family and and former co workers and former clients also 107 00:06:50,200 --> 00:06:54,159 Speaker 1: invested in their early start up, and they raised about 108 00:06:54,160 --> 00:06:57,280 Speaker 1: four hundred thousand dollars, which originally they thought would be 109 00:06:57,440 --> 00:06:59,800 Speaker 1: enough to get them to the point where they could 110 00:06:59,800 --> 00:07:04,680 Speaker 1: bringing a product to market. Later fundraising efforts got them 111 00:07:04,720 --> 00:07:07,960 Speaker 1: further once they realized that four thousand dollars was not 112 00:07:08,080 --> 00:07:10,080 Speaker 1: going to be enough, But that was a little bit 113 00:07:10,120 --> 00:07:12,040 Speaker 1: further down the line. They had a long way to 114 00:07:12,080 --> 00:07:14,560 Speaker 1: go before they actually had a physical product they could 115 00:07:14,600 --> 00:07:19,080 Speaker 1: show off. Their ideas. Sound sounded really good. They were 116 00:07:19,120 --> 00:07:23,920 Speaker 1: really sound ideas, but neither co founder had any experience 117 00:07:24,280 --> 00:07:27,360 Speaker 1: in the manufacturing world, so neither of them knew anything 118 00:07:27,400 --> 00:07:31,280 Speaker 1: about product development or actually taking an idea and making 119 00:07:31,280 --> 00:07:33,800 Speaker 1: a physical thing out of it, and as it turns out, 120 00:07:33,880 --> 00:07:38,560 Speaker 1: that's really hard to do. They had to make a 121 00:07:38,560 --> 00:07:40,680 Speaker 1: working prototype in order to show it off to some 122 00:07:40,720 --> 00:07:45,640 Speaker 1: potential investors and also potential customers. So the original fitbit 123 00:07:45,680 --> 00:07:49,160 Speaker 1: prototype didn't look very special. It was some circuitry in 124 00:07:49,200 --> 00:07:51,120 Speaker 1: a little wooden box. I think it was even made 125 00:07:51,120 --> 00:07:55,400 Speaker 1: of balsa would The idea seemed really special, though, and 126 00:07:55,480 --> 00:07:57,920 Speaker 1: Park and Freedmen were determined to make it work, so 127 00:07:58,960 --> 00:08:02,120 Speaker 1: they needed to develop the product that could be lightweight 128 00:08:02,520 --> 00:08:04,120 Speaker 1: because you wanted to be able to wear it on 129 00:08:04,200 --> 00:08:08,040 Speaker 1: your body. They wanted it to be very energy efficient 130 00:08:08,080 --> 00:08:10,440 Speaker 1: because you don't want to have to recharge it constantly. 131 00:08:11,440 --> 00:08:13,600 Speaker 1: They wanted to aim for a price point of around 132 00:08:15,080 --> 00:08:19,040 Speaker 1: in the US dollars. That is, the original fitbit tracker 133 00:08:19,080 --> 00:08:22,120 Speaker 1: that they eventually developed was a clip on device. You 134 00:08:22,120 --> 00:08:25,320 Speaker 1: could clip it on pocket or a lot of the 135 00:08:25,400 --> 00:08:28,160 Speaker 1: ladies would clip it on a bra strap or something 136 00:08:28,200 --> 00:08:31,680 Speaker 1: along those lines. Um And it was kind of like 137 00:08:31,720 --> 00:08:36,199 Speaker 1: a high tech clothes pin almost. So it had a 138 00:08:36,360 --> 00:08:42,360 Speaker 1: very small, oh lead display, uh you know, organic led display, 139 00:08:42,640 --> 00:08:44,440 Speaker 1: and that could show you how many steps you took. 140 00:08:44,760 --> 00:08:47,760 Speaker 1: Give me a little indicator had little footprints on it too. 141 00:08:48,160 --> 00:08:50,480 Speaker 1: I'm looking at the camera that I'm talking to. I'm 142 00:08:50,520 --> 00:08:54,600 Speaker 1: live streaming this particular episode, and I'm acting like it's 143 00:08:54,600 --> 00:08:58,160 Speaker 1: actually another person right there. So that's interesting. But at 144 00:08:58,160 --> 00:09:00,880 Speaker 1: any rate, the this little screen and show you the 145 00:09:00,960 --> 00:09:03,640 Speaker 1: number of steps you took. And it also had a 146 00:09:03,679 --> 00:09:08,120 Speaker 1: Bluetooth low energy transmitter incorporated in the device in order 147 00:09:08,120 --> 00:09:12,199 Speaker 1: to send information to a sinking station sinking as in synchronization, 148 00:09:12,320 --> 00:09:15,760 Speaker 1: not as in sinking under the water, and you would 149 00:09:15,760 --> 00:09:19,400 Speaker 1: plug that into a computer, so your device would sink 150 00:09:19,440 --> 00:09:23,080 Speaker 1: whenever you got within a certain range uh and it 151 00:09:23,120 --> 00:09:25,920 Speaker 1: would do so multiple times over the course of a day, 152 00:09:26,200 --> 00:09:29,240 Speaker 1: so maybe every like fifteen to twenty minutes it would update, 153 00:09:30,360 --> 00:09:34,440 Speaker 1: and then you could view stats on your computer screen. 154 00:09:34,880 --> 00:09:39,040 Speaker 1: Later on, with smartphones became ubiquitous and a lot of 155 00:09:39,080 --> 00:09:42,439 Speaker 1: apps were developed for the fitbit, you could offload that 156 00:09:42,559 --> 00:09:46,720 Speaker 1: to a smartphone and just use a Bluetooth connection between 157 00:09:46,880 --> 00:09:50,640 Speaker 1: a device and your smartphone to send that information. But 158 00:09:50,720 --> 00:09:54,560 Speaker 1: either way, the point was you could then view more 159 00:09:54,840 --> 00:09:59,480 Speaker 1: robust information on a dashboard, either on your computer or 160 00:09:59,559 --> 00:10:02,320 Speaker 1: later on on your smartphone, and it would give you 161 00:10:02,400 --> 00:10:04,480 Speaker 1: a little bit better of an idea of of what 162 00:10:04,600 --> 00:10:09,040 Speaker 1: your activity actually meant. Because a predometer can tell you 163 00:10:09,320 --> 00:10:13,400 Speaker 1: roughly how many steps you took, but fitbits value proposition 164 00:10:13,440 --> 00:10:18,840 Speaker 1: was that it could do more than that. So while 165 00:10:18,880 --> 00:10:21,560 Speaker 1: the fitbit tracker could estimate the number of steps you 166 00:10:21,679 --> 00:10:24,520 Speaker 1: were taking, that one of the things that this dashboard 167 00:10:24,520 --> 00:10:27,880 Speaker 1: could do is estimate how many calories you were burning 168 00:10:27,920 --> 00:10:31,560 Speaker 1: based upon the nature and duration of the movement you 169 00:10:31,600 --> 00:10:35,000 Speaker 1: were making, and it did this by collecting information from 170 00:10:35,040 --> 00:10:37,840 Speaker 1: a three axis accelerometer and more on that in a 171 00:10:37,840 --> 00:10:43,240 Speaker 1: little bit. I'll actually explain how three axes accelerometers work. Really, 172 00:10:43,240 --> 00:10:46,920 Speaker 1: I should say just a three axis accelerometers work. And 173 00:10:47,720 --> 00:10:52,000 Speaker 1: this was really what was compelling about their approach was 174 00:10:52,080 --> 00:10:56,000 Speaker 1: that wasn't just a physical product that they were marketing. 175 00:10:56,280 --> 00:10:59,719 Speaker 1: It was this whole marriage between software and hardware that 176 00:10:59,840 --> 00:11:04,280 Speaker 1: together made it a product that people might want and 177 00:11:04,760 --> 00:11:10,600 Speaker 1: would find compelling uses for. Like this whole uh new 178 00:11:10,720 --> 00:11:15,199 Speaker 1: industry of activity tracking, quantifying your activity in a way 179 00:11:15,240 --> 00:11:18,360 Speaker 1: that makes sense, so that you could perhaps set goals 180 00:11:18,360 --> 00:11:21,560 Speaker 1: saying I want to hit a certain milestone today, or 181 00:11:21,679 --> 00:11:24,480 Speaker 1: you could just see what trends were for a week 182 00:11:24,559 --> 00:11:26,480 Speaker 1: and maybe there were things that you needed to adjust. 183 00:11:27,080 --> 00:11:30,320 Speaker 1: It was a new idea really that you would be 184 00:11:30,360 --> 00:11:33,000 Speaker 1: able to gather that much information and have it presented 185 00:11:33,040 --> 00:11:35,160 Speaker 1: to you in a way that made sense, and that, 186 00:11:35,240 --> 00:11:39,280 Speaker 1: I think, more than just the tracker itself, is what 187 00:11:39,520 --> 00:11:44,120 Speaker 1: got people really interested. So let's talk about how this 188 00:11:44,200 --> 00:11:48,040 Speaker 1: hardware works. Will begin with what is arguably the most 189 00:11:48,120 --> 00:11:55,040 Speaker 1: important element in fitbit technology, which is the three axis accelerometer. Uh. 190 00:11:55,080 --> 00:11:58,040 Speaker 1: There are of course a lot of other components inside fitbits, 191 00:11:58,040 --> 00:12:00,800 Speaker 1: and it also depends upon which fit bit model you're 192 00:12:00,800 --> 00:12:05,200 Speaker 1: talking about because Fitbit offers a ton of different products, 193 00:12:05,280 --> 00:12:08,040 Speaker 1: and some of them are more simple, and some of 194 00:12:08,040 --> 00:12:12,360 Speaker 1: them are have all the bells and whistles. Figuratively speaking, 195 00:12:12,360 --> 00:12:15,040 Speaker 1: I don't think any of Fitbit's current products actually have 196 00:12:15,120 --> 00:12:19,480 Speaker 1: physical bells or whistles, So I apologize if I got 197 00:12:19,520 --> 00:12:25,480 Speaker 1: your hopes up. So, the three axis accelerometer is an 198 00:12:25,520 --> 00:12:32,240 Speaker 1: interesting thing. Uh It It detects changes in motion. That's 199 00:12:32,280 --> 00:12:36,679 Speaker 1: what accelerometers do. They detect changes in acceleration, and acceleration 200 00:12:36,920 --> 00:12:40,480 Speaker 1: is a vector quantity, right, It has two components. It 201 00:12:40,520 --> 00:12:44,440 Speaker 1: has a direction, and it has a magnitude. So an 202 00:12:44,440 --> 00:12:48,080 Speaker 1: accelerometer can detect a change in the direction of motion 203 00:12:48,240 --> 00:12:51,320 Speaker 1: or a change in the magnitude of motion, and a 204 00:12:51,440 --> 00:12:56,240 Speaker 1: single axis accelerometer can only tell the difference in a 205 00:12:56,400 --> 00:13:00,679 Speaker 1: change in direction along one axis. So upper down is 206 00:13:00,720 --> 00:13:04,280 Speaker 1: an axis. If you have a single access accelerometer and 207 00:13:04,280 --> 00:13:07,560 Speaker 1: it's oriented in the up down position, it can only 208 00:13:07,600 --> 00:13:12,000 Speaker 1: detect changes in direction that that an impact up or down. 209 00:13:12,040 --> 00:13:16,840 Speaker 1: It cannot detect left or right. So uh, three axis 210 00:13:16,880 --> 00:13:20,079 Speaker 1: means that there are three axis of directions that you're 211 00:13:20,080 --> 00:13:23,160 Speaker 1: talking about, essentially up, down, left, right, and forward backward. 212 00:13:23,640 --> 00:13:25,640 Speaker 1: So you can detect changes in motion and all of 213 00:13:25,679 --> 00:13:30,720 Speaker 1: these different axes. The accelerometers inside fitbits are specific types. 214 00:13:30,720 --> 00:13:34,680 Speaker 1: They're called MEMS accelerometers m E m S, and that's 215 00:13:34,679 --> 00:13:38,959 Speaker 1: actually an acronym. It stands for micro electro mechanical systems. 216 00:13:39,720 --> 00:13:42,000 Speaker 1: And this is the fascinating thing to me. These are 217 00:13:42,120 --> 00:13:44,440 Speaker 1: very very tiny. They're they're like, it looks like a 218 00:13:44,480 --> 00:13:48,280 Speaker 1: regular little micro chip, like a microprocessor chip, but they 219 00:13:48,320 --> 00:13:52,120 Speaker 1: actually have tiny moving parts inside of them. The accelerometers 220 00:13:52,160 --> 00:13:56,760 Speaker 1: are actually based upon physical motion. Uh. And the name 221 00:13:56,800 --> 00:13:59,080 Speaker 1: tells you all the basics you need to know. Micro 222 00:13:59,240 --> 00:14:03,880 Speaker 1: means we're talking wicked small here. Um, that means they're tiny. 223 00:14:03,960 --> 00:14:06,040 Speaker 1: If you're not from Boston, you don't know what wicked 224 00:14:06,080 --> 00:14:10,360 Speaker 1: small means. It means tiny. Electro of course, means that 225 00:14:10,400 --> 00:14:13,480 Speaker 1: you have some sort of electrical or electro magnetic component 226 00:14:13,559 --> 00:14:16,360 Speaker 1: to it. And mechanical tells you that, yeah, we're talking 227 00:14:16,360 --> 00:14:19,880 Speaker 1: about moving parts here. It's just not you know, not 228 00:14:19,960 --> 00:14:23,720 Speaker 1: just electrons zipping around. They're actually tiny little movement moving 229 00:14:23,760 --> 00:14:28,040 Speaker 1: elements to this thing. So let's start with a simple 230 00:14:28,080 --> 00:14:32,880 Speaker 1: single access accelerometer. And again by access, we're talking about 231 00:14:32,920 --> 00:14:37,240 Speaker 1: a specific set of directions. Um, this is all with 232 00:14:37,320 --> 00:14:41,000 Speaker 1: respect to the accelerometers orientation. So let's say we've got 233 00:14:41,000 --> 00:14:45,440 Speaker 1: a macro sized single access accelerometer sitting on the table. 234 00:14:45,480 --> 00:14:50,120 Speaker 1: This is easier to envision. It can measure accelerator accelerative 235 00:14:50,160 --> 00:14:52,480 Speaker 1: forces that are going up or down, but not left 236 00:14:52,560 --> 00:14:56,080 Speaker 1: or right, or forward or backward, because it's again single access. 237 00:14:56,120 --> 00:14:59,800 Speaker 1: But the way it works is that you've got a 238 00:14:59,840 --> 00:15:03,120 Speaker 1: b ace, which in the micro scale we would call 239 00:15:03,160 --> 00:15:06,520 Speaker 1: a substrate. We'll just say it's the surface of a 240 00:15:06,560 --> 00:15:10,680 Speaker 1: table in this case. Then you would have a spring, 241 00:15:11,280 --> 00:15:14,200 Speaker 1: a pretty stiff spring, not not like a slinky, but 242 00:15:14,240 --> 00:15:17,080 Speaker 1: more like maybe something you would find in a shock absorber. 243 00:15:18,080 --> 00:15:21,480 Speaker 1: Attached to the spring, you would have some sort of 244 00:15:21,960 --> 00:15:28,600 Speaker 1: element that would have flat protrusions extending from the sides. 245 00:15:28,800 --> 00:15:32,960 Speaker 1: So imagine like a cylinder, and along the length of 246 00:15:32,960 --> 00:15:36,600 Speaker 1: the cylinder you've got these flat protrusions their plates, is 247 00:15:36,600 --> 00:15:39,440 Speaker 1: what they're called. These are movable plates because they're on 248 00:15:39,480 --> 00:15:42,560 Speaker 1: the cylinder, which itself is on a spring. So an 249 00:15:42,600 --> 00:15:45,520 Speaker 1: emotion on the spring will make the cylinder go up 250 00:15:45,520 --> 00:15:47,880 Speaker 1: and down, which means the plates, which are attached to 251 00:15:47,880 --> 00:15:53,000 Speaker 1: the cylinder will also go up or down. Now, around 252 00:15:53,000 --> 00:15:57,440 Speaker 1: this cylinder You've got some fixed plates mounted to a 253 00:15:57,560 --> 00:16:00,840 Speaker 1: steady frame, so the frame does not move, the frame 254 00:16:00,920 --> 00:16:06,640 Speaker 1: stays stable, but those plates sandwich the moving plates. So 255 00:16:06,680 --> 00:16:11,800 Speaker 1: a moving plate would slide between two fixed plates, and 256 00:16:11,840 --> 00:16:16,520 Speaker 1: then you apply of different voltages to each pair of 257 00:16:16,560 --> 00:16:20,720 Speaker 1: fixed plates, so you've got a difference in voltage. They're 258 00:16:20,800 --> 00:16:24,080 Speaker 1: essentially capacitors in this case, they're building up a voltage 259 00:16:24,080 --> 00:16:27,600 Speaker 1: differential between two plates. You've got this moving plate that's 260 00:16:27,680 --> 00:16:31,560 Speaker 1: in between the two. Any motion that you transfer to 261 00:16:31,600 --> 00:16:34,400 Speaker 1: that spring will they be transferred to the cylinder, and 262 00:16:34,440 --> 00:16:37,560 Speaker 1: thus the moving plates they'll move up and down. As 263 00:16:37,560 --> 00:16:39,680 Speaker 1: they move up and down, that moving plate is going 264 00:16:39,720 --> 00:16:42,920 Speaker 1: to get closer to the top plate, and then further 265 00:16:42,960 --> 00:16:45,760 Speaker 1: away and closer to the bottom plate, and then further away. 266 00:16:45,800 --> 00:16:48,160 Speaker 1: So as it moves up and down and gets closer 267 00:16:48,160 --> 00:16:52,440 Speaker 1: and further away from these these fixed plates, it actually 268 00:16:52,480 --> 00:16:57,960 Speaker 1: affects the capacitive value between the two. This difference in 269 00:16:58,000 --> 00:17:03,800 Speaker 1: capacity value is is interpreted by the accelerometer as a 270 00:17:03,920 --> 00:17:08,280 Speaker 1: change in acceleration. And I realized that this is kind 271 00:17:08,280 --> 00:17:12,160 Speaker 1: of a difficult thing to to just imagine that. I'm 272 00:17:12,200 --> 00:17:15,160 Speaker 1: explaining it as best I can, but without the element 273 00:17:15,320 --> 00:17:20,280 Speaker 1: of visuals. It is pretty tricky. So maybe what I 274 00:17:20,320 --> 00:17:26,880 Speaker 1: can do is, um, I'll explain it analogy. I love analogies. 275 00:17:27,040 --> 00:17:29,840 Speaker 1: And uh, it was lunchtime not too long ago here 276 00:17:29,920 --> 00:17:33,440 Speaker 1: in Atlanta, Georgia. So I'm going to talk about sandwich. 277 00:17:34,359 --> 00:17:38,360 Speaker 1: Imagine a really delicious veggie burger, and they do exist. 278 00:17:39,280 --> 00:17:41,119 Speaker 1: It's easy to find a bad one, but trust me, 279 00:17:41,160 --> 00:17:43,600 Speaker 1: the good ones are out there too. Now, imagine you've 280 00:17:43,640 --> 00:17:48,760 Speaker 1: got a bottom bun sitting on a table, hovering, as 281 00:17:48,800 --> 00:17:51,840 Speaker 1: if by magic. About two inches above that bun is 282 00:17:51,880 --> 00:17:55,600 Speaker 1: a veggie patty, and it is in fact delicious, but 283 00:17:55,680 --> 00:17:57,639 Speaker 1: you can't eat it yet because I need it for 284 00:17:57,680 --> 00:18:02,359 Speaker 1: this analogy. Hovering about two inches above that is the 285 00:18:02,400 --> 00:18:06,000 Speaker 1: top bun. So you've got some space between the top bun, 286 00:18:06,359 --> 00:18:09,280 Speaker 1: the veggie patty, and the bottom bun. Now, the two 287 00:18:09,280 --> 00:18:13,800 Speaker 1: buns are fixed in space and time. Not even the 288 00:18:13,920 --> 00:18:18,760 Speaker 1: Juggernaut himself could move the two buns. They are going 289 00:18:18,800 --> 00:18:22,920 Speaker 1: to remain in the positions they are in until the 290 00:18:23,040 --> 00:18:29,840 Speaker 1: universe itself burns out. But the veggie patty can move 291 00:18:30,000 --> 00:18:33,560 Speaker 1: up and down. It has that freedom of movement. So 292 00:18:33,600 --> 00:18:36,880 Speaker 1: any motion to the table is going to make that 293 00:18:36,960 --> 00:18:40,280 Speaker 1: veggie Patty either get closer to the top bun or 294 00:18:40,359 --> 00:18:43,520 Speaker 1: the bottom bun. And that's what I'm talking about. It's 295 00:18:43,600 --> 00:18:47,080 Speaker 1: it's very similar with an accelerometer, except instead of veggie burger, 296 00:18:47,520 --> 00:18:51,520 Speaker 1: you've got these moving plates and fixed plates, and instead 297 00:18:51,560 --> 00:18:54,960 Speaker 1: of deliciousness, you have a capacitive value based upon a 298 00:18:55,040 --> 00:19:00,320 Speaker 1: voltage differential between two plates. Simple right. Anyway, you have 299 00:19:00,400 --> 00:19:05,600 Speaker 1: processors that can take that data, that change in the 300 00:19:05,680 --> 00:19:10,240 Speaker 1: capacitive value and interpret it as acceleration, and based upon 301 00:19:10,400 --> 00:19:14,880 Speaker 1: the speed of the change and the magnitude of the change, 302 00:19:15,000 --> 00:19:18,200 Speaker 1: it can make some guesses as to how much accelerative 303 00:19:18,280 --> 00:19:23,800 Speaker 1: force is being applied. So if you've ever used a 304 00:19:23,840 --> 00:19:26,800 Speaker 1: fitness tracker that could tell the difference between when you 305 00:19:26,840 --> 00:19:29,720 Speaker 1: were walking versus when you might be typing on a 306 00:19:29,800 --> 00:19:33,360 Speaker 1: keyboard or when you're jogging down the street, it's because 307 00:19:33,440 --> 00:19:38,560 Speaker 1: the accelerometer is able to interpret these differences and then 308 00:19:38,920 --> 00:19:41,800 Speaker 1: present that information in a way that makes sense to you. 309 00:19:42,800 --> 00:19:45,320 Speaker 1: And it's all about just looking at the math of 310 00:19:45,359 --> 00:19:48,119 Speaker 1: the difference of that capacitive value, which to me is 311 00:19:48,800 --> 00:19:51,600 Speaker 1: it's almost akin to magic. I'm about to go all 312 00:19:51,720 --> 00:19:57,480 Speaker 1: Arthur C. Clark in here. So that's a basic single 313 00:19:57,560 --> 00:20:00,960 Speaker 1: access accelerometer, and the same thing is happening inside the 314 00:20:01,000 --> 00:20:03,480 Speaker 1: sensors on the fitbit, only we're talking about a much 315 00:20:03,600 --> 00:20:07,600 Speaker 1: much much smaller accelerometer, right, We're talking micro level, not 316 00:20:07,920 --> 00:20:13,200 Speaker 1: macro level. And again, they don't use single axis accelerometers 317 00:20:13,200 --> 00:20:16,119 Speaker 1: because that would only detect a change in acceleration along 318 00:20:16,240 --> 00:20:20,240 Speaker 1: one axis. They use three axis accelerometers. So how are 319 00:20:19,960 --> 00:20:23,280 Speaker 1: those different, Well, they're not different. You just get three 320 00:20:23,320 --> 00:20:27,040 Speaker 1: single axis accelerometers and then you orient them so that 321 00:20:27,119 --> 00:20:30,240 Speaker 1: they have these ninety degree changes, so that you've got 322 00:20:30,680 --> 00:20:33,960 Speaker 1: one that's aligned up and down, one that's the line 323 00:20:34,040 --> 00:20:37,000 Speaker 1: left and right, and one that's aligned front to back, 324 00:20:37,480 --> 00:20:39,800 Speaker 1: and they're all next to each other. And it doesn't 325 00:20:39,800 --> 00:20:42,040 Speaker 1: you know, they're not always going to be. This is vertical, 326 00:20:42,080 --> 00:20:45,200 Speaker 1: this is horizontal, and this is your your Z axis 327 00:20:45,760 --> 00:20:50,280 Speaker 1: because it all depends upon the orientation of the fitbit itself. Right, 328 00:20:50,359 --> 00:20:52,280 Speaker 1: Sometimes i might have my arm way up in the air, 329 00:20:52,440 --> 00:20:55,000 Speaker 1: waving it around as if in fact I just did 330 00:20:55,040 --> 00:20:59,200 Speaker 1: not care. But other times I'm gonna be just hauling 331 00:20:59,800 --> 00:21:02,399 Speaker 1: as fast as I can down the highway while the 332 00:21:02,440 --> 00:21:06,000 Speaker 1: T one thousand is chasing me down. And the important 333 00:21:06,000 --> 00:21:09,639 Speaker 1: thing is these accelerometers have to uh, detect that motion 334 00:21:09,680 --> 00:21:12,640 Speaker 1: no matter what orientation my arm might be in. That's 335 00:21:12,640 --> 00:21:14,520 Speaker 1: why you go with the three axis. It's much more 336 00:21:14,560 --> 00:21:20,040 Speaker 1: accurate than a single access accelerometer. And I love the 337 00:21:20,080 --> 00:21:23,560 Speaker 1: fact that this technology is built on the basis of 338 00:21:23,600 --> 00:21:26,000 Speaker 1: motion because it means that you yourself can go out 339 00:21:26,040 --> 00:21:29,080 Speaker 1: and build an accelerometer if you want to. You can 340 00:21:29,080 --> 00:21:32,080 Speaker 1: build a simple one which would really just give you 341 00:21:32,119 --> 00:21:35,400 Speaker 1: an indication of changes to acceleration based upon the movement 342 00:21:35,680 --> 00:21:38,720 Speaker 1: of a mass at the end of a spring. But 343 00:21:38,800 --> 00:21:41,480 Speaker 1: that's technically kind of an accelerometer doesn't really give you 344 00:21:41,520 --> 00:21:44,160 Speaker 1: any value, So I would argue that perhaps you can't 345 00:21:44,200 --> 00:21:46,880 Speaker 1: really call an accelerometer. It's almost more of a seizmometer. 346 00:21:47,280 --> 00:21:50,240 Speaker 1: But it's still kind of cool. Uh. But yeah, with 347 00:21:50,240 --> 00:21:52,400 Speaker 1: with some springs and a few other pieces of equipment, 348 00:21:52,400 --> 00:21:55,520 Speaker 1: you could make a macro sized accelerometer that works on 349 00:21:55,560 --> 00:21:58,960 Speaker 1: the exact same principle as these very tiny ones that 350 00:21:59,040 --> 00:22:02,440 Speaker 1: you find in fitbit, And then you can marvel and 351 00:22:02,520 --> 00:22:04,760 Speaker 1: the fact that it still works at the micro scale. 352 00:22:06,320 --> 00:22:12,440 Speaker 1: Go ahead, marvel. You can actually marvel all the way 353 00:22:12,480 --> 00:22:15,480 Speaker 1: through the next bit because it's time to take a 354 00:22:15,560 --> 00:22:27,560 Speaker 1: quick break to thank our sponsor. All right, so let's 355 00:22:27,560 --> 00:22:31,520 Speaker 1: talk about other stuff with the fitbit. You know, other 356 00:22:31,600 --> 00:22:37,600 Speaker 1: elements in UH in the fitbit handle actual processing of information. 357 00:22:37,880 --> 00:22:41,040 Speaker 1: So you've got the sensor that's gathering information, the the 358 00:22:41,040 --> 00:22:44,919 Speaker 1: three axis accelerometer. It's it's pulling info in, but that 359 00:22:44,960 --> 00:22:47,720 Speaker 1: needs to be processed, right, It's just kind of raw data. 360 00:22:47,760 --> 00:22:51,439 Speaker 1: It doesn't really have any meaning to it. So we 361 00:22:51,560 --> 00:22:54,520 Speaker 1: then have the other processors to kind of turn that 362 00:22:54,600 --> 00:22:59,520 Speaker 1: into more interesting information that has relevance to us as users. 363 00:23:00,359 --> 00:23:04,679 Speaker 1: Then you've got the low energy Bluetooth transmitter, and that 364 00:23:04,840 --> 00:23:08,520 Speaker 1: is what allows the the fitbit to communicate with other 365 00:23:08,560 --> 00:23:14,160 Speaker 1: devices like smartphones and sinking stations again synchronization stations UH. 366 00:23:14,200 --> 00:23:18,120 Speaker 1: And they use low energy bluetooth because as you would imagine, 367 00:23:18,200 --> 00:23:20,639 Speaker 1: it doesn't require that much energy to operate. It's sending 368 00:23:20,800 --> 00:23:24,000 Speaker 1: very small amounts of data, so it's not like it's 369 00:23:24,040 --> 00:23:27,919 Speaker 1: having to transmit a constant stream of information. It's just 370 00:23:28,280 --> 00:23:31,400 Speaker 1: little packets of information, so it doesn't take a whole 371 00:23:31,400 --> 00:23:33,840 Speaker 1: lot of power to do it, and that means that 372 00:23:33,920 --> 00:23:36,240 Speaker 1: it's less of a drain on battery life because that's 373 00:23:36,240 --> 00:23:39,280 Speaker 1: really important with an activity tracker. You don't. You don't 374 00:23:39,320 --> 00:23:40,920 Speaker 1: want to have to take it off at the end 375 00:23:40,920 --> 00:23:44,560 Speaker 1: of every day and recharge it, especially one like the 376 00:23:44,560 --> 00:23:47,800 Speaker 1: fitbit that's supposed to also track how well you sleep. 377 00:23:48,440 --> 00:23:51,080 Speaker 1: If you're supposed to wear it essentially twenty four hours 378 00:23:51,200 --> 00:23:54,680 Speaker 1: until you actually absolutely have to charge it, you want 379 00:23:54,680 --> 00:23:56,960 Speaker 1: to maximize that battery life. So that was one way 380 00:23:57,000 --> 00:23:59,800 Speaker 1: they could do it was using this low energy Bluetooth approach. 381 00:24:00,040 --> 00:24:02,280 Speaker 1: And I've talked about low too, low energy Bluetooth and 382 00:24:02,400 --> 00:24:04,600 Speaker 1: other podcasts, So if you want to go back to 383 00:24:05,240 --> 00:24:08,800 Speaker 1: Tech Stuff archives, you can find me explaining that technology 384 00:24:08,800 --> 00:24:13,080 Speaker 1: a little bit more. These days, Uh, you know, you're 385 00:24:13,160 --> 00:24:16,520 Speaker 1: more likely to use a smartphone than a synchronize kind 386 00:24:16,520 --> 00:24:19,840 Speaker 1: of station type device that plugs in via USB to 387 00:24:19,920 --> 00:24:23,199 Speaker 1: your computer. You might still do that. I did that 388 00:24:23,240 --> 00:24:25,919 Speaker 1: with my old fitbit, but these days now I just 389 00:24:26,040 --> 00:24:29,640 Speaker 1: used my smartphone essentially is the computer in my pocket. 390 00:24:29,760 --> 00:24:34,960 Speaker 1: So um. But when they first launched Fitbit, smartphones were 391 00:24:35,000 --> 00:24:37,840 Speaker 1: not really a big thing yet. Remember they got together 392 00:24:37,920 --> 00:24:40,080 Speaker 1: to work on Fitbit in two thousand seven. That's the 393 00:24:40,160 --> 00:24:44,600 Speaker 1: same year that Apple debuted the iPhone. So to me, 394 00:24:44,800 --> 00:24:47,560 Speaker 1: that is the beginning of the era of the smartphone age. 395 00:24:47,600 --> 00:24:50,480 Speaker 1: Even though there were other phones that could technically be 396 00:24:50,520 --> 00:24:54,000 Speaker 1: called smartphones before the iPhone, it was the iPhone that 397 00:24:54,080 --> 00:24:58,399 Speaker 1: captured the public imagination so that people besides just the 398 00:24:58,400 --> 00:25:01,879 Speaker 1: the tech geeks like my elf, sat up and said, Oh, 399 00:25:01,920 --> 00:25:05,320 Speaker 1: that's pretty cool. I want one of those now. It 400 00:25:05,359 --> 00:25:08,359 Speaker 1: was actually that that bluetooth transmitter that gave them some 401 00:25:08,480 --> 00:25:12,480 Speaker 1: early problems. If you read review our interviews with the 402 00:25:12,520 --> 00:25:16,200 Speaker 1: founders of Fitbit, they'd say that their company nearly died 403 00:25:16,520 --> 00:25:22,080 Speaker 1: seven times. They had seven different crises that almost killed 404 00:25:22,119 --> 00:25:25,280 Speaker 1: off their company in that that first year, and one 405 00:25:25,320 --> 00:25:27,320 Speaker 1: of them was they found that they were having this 406 00:25:27,400 --> 00:25:31,359 Speaker 1: transmitter problem that the device wasn't able to sink properly. 407 00:25:31,760 --> 00:25:34,720 Speaker 1: Because it wasn't able to transmit information properly, they weren't 408 00:25:34,760 --> 00:25:38,280 Speaker 1: getting any data off of the transmitter, and they found 409 00:25:38,280 --> 00:25:40,679 Speaker 1: out it was an antenna issue, and they fixed it 410 00:25:41,000 --> 00:25:45,160 Speaker 1: by putting some foam behind the antenna, like propping it up, 411 00:25:45,760 --> 00:25:49,159 Speaker 1: which I can identify with. I'm old enough that I 412 00:25:49,200 --> 00:25:52,439 Speaker 1: remember when we would get all of our television programming 413 00:25:52,560 --> 00:25:55,280 Speaker 1: over the air, and I was the official. Hey moved 414 00:25:55,320 --> 00:25:58,280 Speaker 1: the antenna a quarter inch to the left so that 415 00:25:58,320 --> 00:26:00,199 Speaker 1: we can get I love Lucy on the e V 416 00:26:01,840 --> 00:26:06,880 Speaker 1: So I was the piece of foam in my family anyway. Uh. 417 00:26:06,920 --> 00:26:10,000 Speaker 1: These were the kind of like CLUEG solutions they had 418 00:26:10,000 --> 00:26:13,080 Speaker 1: to go with early on just to get their their 419 00:26:13,080 --> 00:26:16,200 Speaker 1: technology working. But the important thing was it actually did 420 00:26:16,600 --> 00:26:20,640 Speaker 1: make it work. Now, while their proof of concept was working, 421 00:26:20,680 --> 00:26:23,880 Speaker 1: they discovered that that food dollars just was not going 422 00:26:23,920 --> 00:26:27,080 Speaker 1: to be nearly enough to bring a product to market. 423 00:26:28,080 --> 00:26:32,240 Speaker 1: They had underestimated how incredibly challenging it is to get 424 00:26:32,240 --> 00:26:37,159 Speaker 1: into manufacturing. It requires creating a supply chain. You have 425 00:26:37,200 --> 00:26:40,200 Speaker 1: to figure out who's going to supply the various little 426 00:26:40,240 --> 00:26:43,520 Speaker 1: components that together make your product. You have to form 427 00:26:43,600 --> 00:26:47,480 Speaker 1: relationships with the various suppliers of microchips and sensors. You 428 00:26:47,520 --> 00:26:50,040 Speaker 1: have to figure out what is the form factor of 429 00:26:50,080 --> 00:26:52,119 Speaker 1: your product going to look like, like what is it 430 00:26:52,200 --> 00:26:54,639 Speaker 1: actually going to how's the design going to be, and 431 00:26:54,680 --> 00:26:57,840 Speaker 1: who's gonna make it, who's gonna cast the molds, who's 432 00:26:57,840 --> 00:27:00,440 Speaker 1: going to produce the plastic. Uh. This is where I 433 00:27:00,480 --> 00:27:02,640 Speaker 1: would talk about China a bit, because they had to 434 00:27:02,680 --> 00:27:05,040 Speaker 1: look at Chinese suppliers. That was one of the ways 435 00:27:05,040 --> 00:27:07,639 Speaker 1: to keep costs down is that and that's what a 436 00:27:07,680 --> 00:27:10,000 Speaker 1: lot of electronics companies do they look to China to 437 00:27:10,040 --> 00:27:13,960 Speaker 1: produce the little various components that are then assembled together 438 00:27:14,000 --> 00:27:16,800 Speaker 1: and then sold in other parts of the world. So 439 00:27:18,080 --> 00:27:21,520 Speaker 1: they realized that they just did not have the money 440 00:27:21,560 --> 00:27:25,000 Speaker 1: to go through this whole process. They needed more, so 441 00:27:25,040 --> 00:27:28,879 Speaker 1: they held some more rounds of venture capital fundraising, and 442 00:27:28,920 --> 00:27:31,800 Speaker 1: they raised some quite a bit of money, like more 443 00:27:31,800 --> 00:27:34,160 Speaker 1: than a couple of million, because by now people were 444 00:27:34,200 --> 00:27:36,399 Speaker 1: starting to pay attention to what it was they were 445 00:27:36,440 --> 00:27:39,719 Speaker 1: working on. But really, I think the turning point in 446 00:27:39,800 --> 00:27:42,960 Speaker 1: that early time happened in September two thousand eight. So 447 00:27:43,000 --> 00:27:45,119 Speaker 1: they got together in two thousand seven, they started working 448 00:27:45,119 --> 00:27:49,440 Speaker 1: on their idea. September two eight, they got an opportunity 449 00:27:49,480 --> 00:27:52,640 Speaker 1: to show off that idea, show off a prototype, and 450 00:27:52,680 --> 00:27:56,800 Speaker 1: explain their sales pitch, and they did an event called 451 00:27:57,200 --> 00:28:01,199 Speaker 1: tech Crunch fifty uh So tech Crunch they're known for 452 00:28:01,280 --> 00:28:04,199 Speaker 1: lots of stuff. They're they're great with technology news, but 453 00:28:04,240 --> 00:28:09,080 Speaker 1: they also are really a launch point for startups. They 454 00:28:09,119 --> 00:28:13,720 Speaker 1: give startups an opportunity to meet with people, to express 455 00:28:13,760 --> 00:28:15,880 Speaker 1: what it is they are working on and to try 456 00:28:15,880 --> 00:28:18,160 Speaker 1: and see if there's any interest or support out there 457 00:28:18,560 --> 00:28:23,000 Speaker 1: to continue the work. So tech Crunch fifty was a 458 00:28:23,080 --> 00:28:25,720 Speaker 1: huge deal for these guys to be involved with it, 459 00:28:26,560 --> 00:28:31,159 Speaker 1: and they landed a spot in that two thousand eight event. Now, 460 00:28:31,800 --> 00:28:37,160 Speaker 1: going into it, they weren't exactly overwhelmed with optimism. In fact, 461 00:28:37,840 --> 00:28:40,520 Speaker 1: Freedman had said, I don't think more than five people 462 00:28:40,560 --> 00:28:43,200 Speaker 1: will be stupid enough to give us their credit card, 463 00:28:44,480 --> 00:28:48,760 Speaker 1: a somewhat cynical statement, and part of wasn't a whole 464 00:28:48,800 --> 00:28:51,720 Speaker 1: lot better. He said, Nah, you're wrong, We'll get way 465 00:28:51,760 --> 00:28:55,280 Speaker 1: more than five. I bet we'll get fifty orders five zero. 466 00:28:56,000 --> 00:29:00,600 Speaker 1: Turned out that they were grossly underestimating the appeal of 467 00:29:00,640 --> 00:29:04,600 Speaker 1: this Fitbit product. By the end of the day after 468 00:29:04,680 --> 00:29:08,400 Speaker 1: they had presented their idea, they had two thousand pre orders, 469 00:29:09,560 --> 00:29:11,640 Speaker 1: these for two guys who had not yet figured out 470 00:29:11,640 --> 00:29:14,520 Speaker 1: how they were going to produce these these products. They 471 00:29:14,880 --> 00:29:17,080 Speaker 1: knew how it was gonna work, they had an idea 472 00:29:17,120 --> 00:29:19,280 Speaker 1: of what it needed to look like, but they did 473 00:29:19,320 --> 00:29:22,560 Speaker 1: not have a manufacturing process in place yet to produce 474 00:29:22,560 --> 00:29:25,520 Speaker 1: two thousand. It did not help that Park had said 475 00:29:26,480 --> 00:29:31,720 Speaker 1: that they would have the orders out by Christmas. Now 476 00:29:32,640 --> 00:29:37,200 Speaker 1: the first Fitbit trackers, the original product from Fitbit was 477 00:29:37,240 --> 00:29:39,920 Speaker 1: called the Tracker. There was that little clothes pin, thing 478 00:29:39,960 --> 00:29:44,640 Speaker 1: that could clip onto a pocket or whatever. They shipped 479 00:29:44,640 --> 00:29:49,720 Speaker 1: in December two thousand nine, so they presented in September 480 00:29:49,720 --> 00:29:53,200 Speaker 1: two eight. James Park says they'll be out in time 481 00:29:53,200 --> 00:29:57,440 Speaker 1: for Christmas, and they shipped December two thousand nine, and 482 00:29:57,520 --> 00:29:59,720 Speaker 1: James Park said, well, in my defense, I never said 483 00:29:59,760 --> 00:30:06,440 Speaker 1: wh Christmas. Whack at ashrak. Uh. Yeah, it was kind 484 00:30:06,440 --> 00:30:11,800 Speaker 1: of jokingly saying, yeah, we're a year late, but it 485 00:30:11,840 --> 00:30:16,720 Speaker 1: but it came out. And honestly, that delay really illustrates 486 00:30:16,720 --> 00:30:20,160 Speaker 1: what I was saying earlier that manufacturing is hard. It 487 00:30:20,280 --> 00:30:24,640 Speaker 1: is difficult. It's it's something that even big companies struggle with. 488 00:30:24,720 --> 00:30:26,760 Speaker 1: And these are big companies that have been around for 489 00:30:26,760 --> 00:30:30,720 Speaker 1: for decades and they're in the business of making consumer electronics. 490 00:30:31,160 --> 00:30:34,080 Speaker 1: It's challenging for them and they've been doing it for decades. 491 00:30:34,600 --> 00:30:37,680 Speaker 1: For two guys who had started up this company, it 492 00:30:37,760 --> 00:30:42,720 Speaker 1: was way more challenging. So once you are able to 493 00:30:42,720 --> 00:30:47,400 Speaker 1: crack that manufacturing problem, which is again a non trivial task, 494 00:30:47,640 --> 00:30:51,320 Speaker 1: you can go on to actually do business. And Uh, 495 00:30:51,720 --> 00:30:54,400 Speaker 1: it took them a year longer than what they were anticipating, 496 00:30:54,400 --> 00:30:57,240 Speaker 1: but they were able to actually ship out the fitness tracker, 497 00:30:58,040 --> 00:31:00,600 Speaker 1: and as it turned out, it was incredibly popular. They 498 00:31:00,640 --> 00:31:05,120 Speaker 1: got thousands and thousands of orders and immediately the value 499 00:31:05,160 --> 00:31:08,440 Speaker 1: of fitbit was on the rise. So this was two 500 00:31:08,440 --> 00:31:12,160 Speaker 1: thousand nine and it was met with real enthusiasm. The 501 00:31:12,200 --> 00:31:15,040 Speaker 1: low energy electronics meant that the device could go on 502 00:31:15,160 --> 00:31:18,720 Speaker 1: for several days without ever needing a recharge. The dashboard 503 00:31:18,840 --> 00:31:21,640 Speaker 1: side of things that that view you would get on 504 00:31:21,680 --> 00:31:24,680 Speaker 1: your computer or later on your smartphone meant that the 505 00:31:24,760 --> 00:31:28,200 Speaker 1: user was given so much information that was relevant to 506 00:31:28,240 --> 00:31:31,080 Speaker 1: what they were doing. It had a huge appeal. One 507 00:31:31,120 --> 00:31:34,400 Speaker 1: of the easiest ways to sell anything to anyone is 508 00:31:34,400 --> 00:31:41,160 Speaker 1: to involve them in the the product itself, right to say, 509 00:31:41,880 --> 00:31:44,560 Speaker 1: you are what makes this product special. The way you 510 00:31:44,680 --> 00:31:48,560 Speaker 1: use it is reflected in the results you get, and 511 00:31:48,640 --> 00:31:51,360 Speaker 1: so it's all about you. If you want to sell 512 00:31:51,400 --> 00:31:53,240 Speaker 1: me anything and you tell me it's all about me, 513 00:31:54,280 --> 00:31:58,280 Speaker 1: you're well ahead of the game, because I love me. Anyway, 514 00:32:00,280 --> 00:32:02,520 Speaker 1: On the back end of things, the fitbit researchers were 515 00:32:02,520 --> 00:32:06,080 Speaker 1: starting to work on various algorithms to try and turn 516 00:32:06,320 --> 00:32:09,800 Speaker 1: just a number that says steps into something more meaningful. 517 00:32:10,080 --> 00:32:11,880 Speaker 1: So you may have noticed if you've ever used an 518 00:32:11,920 --> 00:32:15,480 Speaker 1: activity tracker that you will get a notification of how 519 00:32:15,480 --> 00:32:18,680 Speaker 1: many miles you've walked in a day. Well, you can't 520 00:32:18,720 --> 00:32:22,520 Speaker 1: just base that on the number of steps, because your 521 00:32:22,640 --> 00:32:25,280 Speaker 1: stride is going to be a different length from someone 522 00:32:25,280 --> 00:32:28,040 Speaker 1: else's stride. If you have someone who's five ft tall 523 00:32:28,440 --> 00:32:31,360 Speaker 1: and someone else who is six ft six and they 524 00:32:31,400 --> 00:32:35,040 Speaker 1: both walk five thousand steps, I guarantee you the six 525 00:32:35,080 --> 00:32:38,400 Speaker 1: ft six inch tall guy walked further. They took the 526 00:32:38,440 --> 00:32:41,240 Speaker 1: same number of steps. But the person who is six 527 00:32:41,240 --> 00:32:43,520 Speaker 1: ft six inch and I said guy, but honestly, the 528 00:32:43,520 --> 00:32:45,640 Speaker 1: first person that popped in my head is a woman 529 00:32:45,840 --> 00:32:50,320 Speaker 1: I know who is very tall. Their stride is longer, 530 00:32:50,360 --> 00:32:53,840 Speaker 1: so they're going to cover more distance. So part of 531 00:32:53,840 --> 00:32:58,040 Speaker 1: this dashboard experience was users giving information about themselves, like 532 00:32:58,120 --> 00:33:01,800 Speaker 1: their height, so that the estimations could be more accurate. 533 00:33:02,160 --> 00:33:05,040 Speaker 1: Someone who's my height, which is five ft eight is 534 00:33:05,080 --> 00:33:07,320 Speaker 1: not gonna be as walking as far as someone who 535 00:33:07,320 --> 00:33:09,000 Speaker 1: has six ft six even if we took the same 536 00:33:09,080 --> 00:33:11,960 Speaker 1: number of steps. Uh. That was the whole point. So 537 00:33:12,000 --> 00:33:13,800 Speaker 1: if you want to estimate how many miles you walk, 538 00:33:13,840 --> 00:33:15,600 Speaker 1: you need to know the height of the person so 539 00:33:15,640 --> 00:33:19,240 Speaker 1: that you can make that estimation. Also, with calories burning, 540 00:33:19,280 --> 00:33:22,520 Speaker 1: you'd have to make estimations based upon age and other factors, 541 00:33:22,560 --> 00:33:24,680 Speaker 1: and in fact, there's so many factors that a lot 542 00:33:24,720 --> 00:33:28,800 Speaker 1: of people have argued that the calories burned metric that 543 00:33:28,960 --> 00:33:33,360 Speaker 1: you find in various activity trackers is largely meaningless because 544 00:33:34,040 --> 00:33:37,360 Speaker 1: it relies on too many unknown variables. It can only 545 00:33:37,960 --> 00:33:40,240 Speaker 1: really look at things like how much activity did you 546 00:33:40,320 --> 00:33:42,960 Speaker 1: do that day and how frequently did you do it? 547 00:33:43,800 --> 00:33:47,880 Speaker 1: But that doesn't necessarily translate to an easy this is 548 00:33:47,880 --> 00:33:51,240 Speaker 1: how many calories you burned. That being said, it could 549 00:33:51,280 --> 00:33:54,440 Speaker 1: help people when they're trying to make general kind of 550 00:33:54,520 --> 00:33:58,640 Speaker 1: high level decisions about their diet, their activity levels, that 551 00:33:58,720 --> 00:34:01,280 Speaker 1: sort of thing. So it really depends on how you 552 00:34:01,320 --> 00:34:03,520 Speaker 1: look at the products. People who are looking at it 553 00:34:03,640 --> 00:34:08,239 Speaker 1: as a almost hobbyist way to get into fitness saw 554 00:34:08,360 --> 00:34:10,799 Speaker 1: value in it. People who are looking at it as saying, 555 00:34:10,800 --> 00:34:13,600 Speaker 1: you're marketing this more as a medical device. They had 556 00:34:13,640 --> 00:34:17,120 Speaker 1: a lot of harsh criticism to level at fitbit, for 557 00:34:17,160 --> 00:34:20,160 Speaker 1: a good reason, because medical devices have to be far 558 00:34:20,320 --> 00:34:25,400 Speaker 1: more precise, far more accurate than something like an activity tracker. 559 00:34:25,840 --> 00:34:27,960 Speaker 1: But a lot of people were arguing that these two 560 00:34:28,000 --> 00:34:31,960 Speaker 1: camps were not talking the same language, and that Fitbit 561 00:34:32,040 --> 00:34:35,279 Speaker 1: was really aiming itself more toward the hobbyist side than 562 00:34:35,320 --> 00:34:40,040 Speaker 1: the hardcore medical application side. Now it didn't hurt the 563 00:34:40,040 --> 00:34:45,240 Speaker 1: fitbits popularity that they happen to have some savvy into 564 00:34:45,520 --> 00:34:49,680 Speaker 1: social media as well. Right, That incorporation of the social 565 00:34:49,719 --> 00:34:53,839 Speaker 1: aspect in fitbits business plan really helped a great deal. 566 00:34:54,480 --> 00:34:57,520 Speaker 1: They incorporated this ability to connect with friends, and you 567 00:34:57,560 --> 00:35:00,760 Speaker 1: could actually compare how many steps have I taken versus 568 00:35:00,880 --> 00:35:03,960 Speaker 1: how many steps has Matt Frederick taken versus how many 569 00:35:04,000 --> 00:35:07,399 Speaker 1: steps has been Bowland taken? That kind of thing, and 570 00:35:07,760 --> 00:35:11,200 Speaker 1: by comparing them, you could end up either thinking, oh, 571 00:35:11,239 --> 00:35:13,640 Speaker 1: I need to get another two thousand steps in because 572 00:35:13,640 --> 00:35:16,440 Speaker 1: I gotta beat this guy, or maybe you're thinking I'm 573 00:35:16,480 --> 00:35:19,440 Speaker 1: way more active than those slug of beds. And it 574 00:35:19,520 --> 00:35:22,960 Speaker 1: created also a competitive element to fit Bit that they 575 00:35:22,960 --> 00:35:26,960 Speaker 1: weren't necessarily anticipating when they first started to implement the 576 00:35:27,080 --> 00:35:31,920 Speaker 1: social uh features in the fitbit product. But they realized 577 00:35:31,920 --> 00:35:36,120 Speaker 1: that that competitive element drove people to use fitbit more 578 00:35:36,440 --> 00:35:39,520 Speaker 1: and to become kind of Fitbit evangelists because they were 579 00:35:39,560 --> 00:35:42,720 Speaker 1: getting out, they were doing things they wanted to earn steps. 580 00:35:42,880 --> 00:35:45,359 Speaker 1: Anyone who's had an activity tracker, I guarantee you. At 581 00:35:45,440 --> 00:35:48,439 Speaker 1: some point in their lives, they have said, I don't 582 00:35:48,440 --> 00:35:50,520 Speaker 1: even know why I walked. I wasn't wearing my tracker. 583 00:35:50,760 --> 00:35:54,400 Speaker 1: They didn't count, Like somehow those steps don't count unless 584 00:35:54,400 --> 00:35:57,880 Speaker 1: they're being quantified by the activity tracker. Well, that's great 585 00:35:57,880 --> 00:36:00,120 Speaker 1: news for a company like fitbit, because it means that 586 00:36:00,200 --> 00:36:03,319 Speaker 1: people need the product, or they at least think they 587 00:36:03,360 --> 00:36:07,560 Speaker 1: need the product that is selling. And uh, that social 588 00:36:07,560 --> 00:36:10,080 Speaker 1: element would actually come to be a problem a little 589 00:36:10,120 --> 00:36:14,279 Speaker 1: bit later. I'll mention that when we get there, it's saucy. 590 00:36:14,960 --> 00:36:17,440 Speaker 1: By the way, in case you're wondering, I am on 591 00:36:17,560 --> 00:36:21,360 Speaker 1: the top of my fitbit friends list um by about 592 00:36:21,480 --> 00:36:24,839 Speaker 1: fifteen thousand steps per week. But to be fair, I 593 00:36:24,880 --> 00:36:27,560 Speaker 1: also walked to and from work, and I lived several 594 00:36:27,600 --> 00:36:31,000 Speaker 1: miles away from the office, so it's a necessity. I 595 00:36:31,040 --> 00:36:34,680 Speaker 1: don't drive, so that helps me with my steps. It's 596 00:36:34,680 --> 00:36:38,880 Speaker 1: not like I am super physically active compared to the 597 00:36:38,920 --> 00:36:41,840 Speaker 1: people on my list. It's a matter of necessity for me. 598 00:36:43,800 --> 00:36:45,719 Speaker 1: All right. You know what, let's take a moment to 599 00:36:45,760 --> 00:36:50,160 Speaker 1: talk about the awkwardness of social connectivity. You see, one 600 00:36:50,160 --> 00:36:51,960 Speaker 1: of the things that bit also allowed you to do 601 00:36:52,200 --> 00:36:55,959 Speaker 1: is create an exercise diary because the fitbit was really 602 00:36:55,960 --> 00:36:58,920 Speaker 1: good at detecting when you were walking or when you 603 00:36:58,960 --> 00:37:02,080 Speaker 1: were jogging, But a lot of the fitbits weren't waterproof, 604 00:37:02,400 --> 00:37:06,040 Speaker 1: so you couldn't track your your activity when you were swimming. 605 00:37:06,680 --> 00:37:09,680 Speaker 1: Many of them couldn't really tell what was going on 606 00:37:09,719 --> 00:37:12,480 Speaker 1: if you were doing exercises in a gem like let's 607 00:37:12,480 --> 00:37:14,840 Speaker 1: say you're getting on the elliptical, it might not be 608 00:37:14,920 --> 00:37:19,400 Speaker 1: able to track that movement. So the exercise diary feature 609 00:37:19,760 --> 00:37:23,600 Speaker 1: on your dashboard allowed you to enter other activities, get 610 00:37:23,640 --> 00:37:26,960 Speaker 1: an estimation of how many calories you burned doing those activities, 611 00:37:27,160 --> 00:37:29,279 Speaker 1: and then you would factor all of that in for 612 00:37:29,400 --> 00:37:32,040 Speaker 1: your end of the day report, saying here's how many 613 00:37:32,040 --> 00:37:37,640 Speaker 1: calories you burned today. Fitbits said that as a default 614 00:37:37,920 --> 00:37:41,400 Speaker 1: shared setting, meaning that if you were creating an exercise 615 00:37:41,480 --> 00:37:44,960 Speaker 1: diary and you had not changed the default, you were 616 00:37:45,000 --> 00:37:47,840 Speaker 1: sharing all of that information to the general public. You 617 00:37:47,960 --> 00:37:50,040 Speaker 1: might say like, I got on the elliptical for twenty 618 00:37:50,040 --> 00:37:53,080 Speaker 1: five minutes and I burned this many calories, and anyone 619 00:37:53,080 --> 00:37:56,520 Speaker 1: who looks at your profile could see that. But people 620 00:37:56,560 --> 00:37:59,839 Speaker 1: were putting in all sorts of different entries in their 621 00:38:00,040 --> 00:38:04,960 Speaker 1: exercise diaries, including times when they were getting a little romantic, 622 00:38:05,480 --> 00:38:10,879 Speaker 1: getting a little uh intimate, getting busy. In other words, Yeah, 623 00:38:11,000 --> 00:38:16,239 Speaker 1: people were putting down sex as an activity in these 624 00:38:16,280 --> 00:38:20,200 Speaker 1: exercise diaries and getting estimations for how many calories they 625 00:38:20,280 --> 00:38:24,719 Speaker 1: burned during those activities, not necessarily realizing that by default 626 00:38:25,040 --> 00:38:28,840 Speaker 1: this was being shared to everyone out there. So in 627 00:38:28,880 --> 00:38:33,280 Speaker 1: two thousand eleven this information kind of got spread around. 628 00:38:33,360 --> 00:38:36,040 Speaker 1: A lot of blogs had fun with it. They talked 629 00:38:36,080 --> 00:38:40,759 Speaker 1: about how fitbit was inadvertently sharing people's sex lives to 630 00:38:41,040 --> 00:38:44,200 Speaker 1: anyone who was interested, and it was at that point 631 00:38:44,200 --> 00:38:47,600 Speaker 1: that Fitbit decided to change that particular policy and set 632 00:38:47,640 --> 00:38:51,359 Speaker 1: the default to private instead of public, And at that 633 00:38:51,400 --> 00:38:55,560 Speaker 1: point we no longer saw tons of people sharing their 634 00:38:55,600 --> 00:38:59,480 Speaker 1: sex lives unknowingly. If they did, they were doing it 635 00:38:59,480 --> 00:39:01,720 Speaker 1: because they in in and change the setting to public 636 00:39:01,920 --> 00:39:04,440 Speaker 1: from private. Oh if it ben't even win an extra stop. 637 00:39:04,480 --> 00:39:09,880 Speaker 1: They actually contacted search engines and they asked for the 638 00:39:09,920 --> 00:39:13,799 Speaker 1: past diary entries to be removed from search engine indexes, 639 00:39:14,040 --> 00:39:17,160 Speaker 1: so that way you couldn't just search someone's fitbit profile 640 00:39:17,520 --> 00:39:20,680 Speaker 1: and use the search results to go back to an 641 00:39:20,800 --> 00:39:23,719 Speaker 1: archive diary entry that you're not supposed to see. So 642 00:39:23,760 --> 00:39:26,520 Speaker 1: they did take some steps to correct this problem. It 643 00:39:26,560 --> 00:39:28,600 Speaker 1: was a problem that they had created by making that 644 00:39:28,719 --> 00:39:31,520 Speaker 1: default public, but it was also a problem that users 645 00:39:31,560 --> 00:39:36,839 Speaker 1: created by putting in other activities on that exercise stuff. Uh. 646 00:39:37,520 --> 00:39:41,839 Speaker 1: But yeah, that was a little awkward. So fitbit um 647 00:39:42,080 --> 00:39:45,320 Speaker 1: learned the hard way that getting into that social game 648 00:39:46,000 --> 00:39:48,719 Speaker 1: is a little tricky, kin of the same thing as 649 00:39:48,960 --> 00:39:53,239 Speaker 1: getting into manufacturing is a little tricky. After all that, 650 00:39:53,280 --> 00:39:55,680 Speaker 1: the team was going back to work on developing new 651 00:39:55,760 --> 00:39:58,040 Speaker 1: types of Fitbit trackers. Now I'm not going to go 652 00:39:58,080 --> 00:40:01,080 Speaker 1: into every single product that they've made, because that would 653 00:40:01,120 --> 00:40:03,640 Speaker 1: be silly. Uh. There are a lot of them that 654 00:40:03,760 --> 00:40:07,680 Speaker 1: haven't been sold for years. They got replaced by later models. Uh, 655 00:40:07,719 --> 00:40:14,400 Speaker 1: they're They're all various variations, I should say on that 656 00:40:14,480 --> 00:40:19,200 Speaker 1: initial fitness tracker. Some have more components to them, but 657 00:40:19,360 --> 00:40:22,680 Speaker 1: ultimately they all work in a very similar way. So 658 00:40:22,719 --> 00:40:24,480 Speaker 1: it doesn't make sense for me to go into all 659 00:40:24,520 --> 00:40:26,880 Speaker 1: the different types. Again, this isn't a commercial for Fitbit. 660 00:40:27,480 --> 00:40:30,480 Speaker 1: This is just an episode talking about the company and 661 00:40:30,520 --> 00:40:34,760 Speaker 1: their technology and how it works. So I will talk 662 00:40:35,320 --> 00:40:39,719 Speaker 1: a little bit about some of the other components that 663 00:40:39,800 --> 00:40:44,000 Speaker 1: are in Fitbit devices. So the Fitbit tracker that was 664 00:40:44,040 --> 00:40:46,239 Speaker 1: their first device. One of the next ones they had 665 00:40:46,320 --> 00:40:49,240 Speaker 1: was the Fitbit Ultra, which was kind of an updated 666 00:40:49,360 --> 00:40:50,920 Speaker 1: version of the tracker, and one of the things that 667 00:40:51,000 --> 00:40:57,600 Speaker 1: added was an altimeter. Uh. And an altimeter is something 668 00:40:57,640 --> 00:41:02,960 Speaker 1: that measures altitude or distance vertically, right, the difference in 669 00:41:03,120 --> 00:41:08,240 Speaker 1: vertical distance between the altimeter and some fixed object, which 670 00:41:08,880 --> 00:41:12,279 Speaker 1: typically is the ground right sea level, or at least 671 00:41:12,320 --> 00:41:17,480 Speaker 1: ground level. And the way it works is it doesn't 672 00:41:17,600 --> 00:41:23,120 Speaker 1: measure directly the distance between it's vertical position in the ground. 673 00:41:23,920 --> 00:41:27,960 Speaker 1: It measures altitude by looking at something related but different 674 00:41:28,360 --> 00:41:32,719 Speaker 1: atmospheric pressure. Now we're gonna go into some basic science time, 675 00:41:32,800 --> 00:41:35,399 Speaker 1: and I know most of you are familiar with this, 676 00:41:35,480 --> 00:41:38,000 Speaker 1: but you know, I always like to have a little refresher. 677 00:41:38,640 --> 00:41:42,640 Speaker 1: The atmosphere that we breathe, it has weight to it, right, 678 00:41:42,960 --> 00:41:46,839 Speaker 1: It's a fluid, and typically we're at the bottom of 679 00:41:46,880 --> 00:41:49,600 Speaker 1: it because we're on ground level or somewhere close to it. 680 00:41:50,000 --> 00:41:54,279 Speaker 1: Not all the time, obviously, but frequently. So if you 681 00:41:54,320 --> 00:41:57,080 Speaker 1: ever felt that you're constantly under pressure, you kind of are, 682 00:41:58,040 --> 00:42:00,759 Speaker 1: at least from the atmosphere. But it's good because if 683 00:42:00,760 --> 00:42:02,360 Speaker 1: you weren't, we wouldn't be able to breathe and you 684 00:42:02,360 --> 00:42:06,040 Speaker 1: would die. So sometimes pressure as good as web saying, 685 00:42:08,600 --> 00:42:13,120 Speaker 1: as you climb in elevation, as you move up a ladder, 686 00:42:13,480 --> 00:42:17,160 Speaker 1: go up some stairs, climb a mountain, get in an airplane, 687 00:42:18,560 --> 00:42:21,560 Speaker 1: you end up having less of this fluid above you 688 00:42:22,040 --> 00:42:24,120 Speaker 1: than you did before. Right, some of that fluids now 689 00:42:24,160 --> 00:42:27,640 Speaker 1: below you. The weight has decreased as you go up 690 00:42:28,400 --> 00:42:32,400 Speaker 1: because you have less atmosphere overhead. It makes sense, right, 691 00:42:32,440 --> 00:42:36,799 Speaker 1: there's less pressing down on you, So there's less weight now. 692 00:42:36,840 --> 00:42:39,520 Speaker 1: If you go far enough, like you climb a tall mountain, 693 00:42:40,280 --> 00:42:42,640 Speaker 1: the pressure changes can be enough to actually have a 694 00:42:42,640 --> 00:42:45,160 Speaker 1: physical effect on you. Most of the time, it's so 695 00:42:45,200 --> 00:42:48,479 Speaker 1: subtle that we cannot detect it by ourselves. We would 696 00:42:48,520 --> 00:42:51,920 Speaker 1: have to have some sort of sensitive instrument in order 697 00:42:51,960 --> 00:42:57,520 Speaker 1: to detect that change. It's also why modern jets are pressurized, 698 00:42:57,920 --> 00:43:01,920 Speaker 1: because if they were unpressurized traveling at thirty ft, the 699 00:43:01,960 --> 00:43:05,959 Speaker 1: atmosphere would be so thin that it would be not 700 00:43:05,960 --> 00:43:10,200 Speaker 1: not not fun times, very not fun times. So you 701 00:43:10,280 --> 00:43:14,120 Speaker 1: pressurize the interior of your plane for a couple of reasons. 702 00:43:14,160 --> 00:43:16,480 Speaker 1: One to make breathing easier to you don't want your 703 00:43:16,480 --> 00:43:21,279 Speaker 1: ear drums to blow out suddenly. Um, So it's really 704 00:43:21,320 --> 00:43:25,440 Speaker 1: important same thing is true for people who are climbing mountains. 705 00:43:25,520 --> 00:43:29,120 Speaker 1: Often you are told that you have to acclimate to 706 00:43:29,760 --> 00:43:33,920 Speaker 1: air pressure at certain stages of tall mountains, otherwise you 707 00:43:34,000 --> 00:43:38,759 Speaker 1: run at the risk of getting sick from altitude sickness. Well, 708 00:43:38,800 --> 00:43:44,000 Speaker 1: altimeters detect air pressure and changes in air pressure, and 709 00:43:44,200 --> 00:43:47,440 Speaker 1: they track things like how many stairs you've climbed by 710 00:43:47,480 --> 00:43:51,000 Speaker 1: detecting those changes in air pressure. The altimeter sensor on 711 00:43:51,040 --> 00:43:53,319 Speaker 1: a fitbit is sensitive enough to detect when you have 712 00:43:53,440 --> 00:43:57,520 Speaker 1: changed ten feet in elevation, whether you're going ten feet 713 00:43:57,600 --> 00:44:01,160 Speaker 1: up or ten feet down, but it only counts stairs 714 00:44:01,200 --> 00:44:04,000 Speaker 1: climbed if you're going up. So, in other words, if 715 00:44:04,000 --> 00:44:07,880 Speaker 1: the atmospheric pressure is decreasing to the point that the 716 00:44:07,920 --> 00:44:11,960 Speaker 1: fitbit says, oh, this guy's gone ten feet up, they've 717 00:44:12,000 --> 00:44:16,200 Speaker 1: climbed some stairs. But if it increases, indicating that you're 718 00:44:16,239 --> 00:44:18,920 Speaker 1: moving downward, it doesn't count it as stairs climbed. And 719 00:44:18,960 --> 00:44:21,719 Speaker 1: that's largely because if you're going downstairs, you don't have 720 00:44:21,760 --> 00:44:23,640 Speaker 1: to exert as much energy as you would if you're 721 00:44:23,640 --> 00:44:26,600 Speaker 1: climbing upstairs. So really you should only be interested in 722 00:44:26,640 --> 00:44:28,680 Speaker 1: how many stairs did you climb, not how many stairs 723 00:44:28,680 --> 00:44:31,319 Speaker 1: did you descend. That's why it doesn't count it if 724 00:44:31,400 --> 00:44:36,680 Speaker 1: you're going down. Uh. I've noticed that that my fitbit 725 00:44:37,360 --> 00:44:40,720 Speaker 1: will sometimes detect a hill as a set of stairs. 726 00:44:40,760 --> 00:44:43,440 Speaker 1: So if it bit tries to determine whether you're climbing 727 00:44:43,440 --> 00:44:46,640 Speaker 1: stairs versus walking up an inclined path by combining the 728 00:44:46,760 --> 00:44:49,840 Speaker 1: data from the altimeter, So how much change in elevation 729 00:44:49,880 --> 00:44:53,680 Speaker 1: have you experienced with the actual motion data from the 730 00:44:53,760 --> 00:44:58,719 Speaker 1: three axis accelerometers which tell how frequently you're moving your arms, 731 00:44:58,800 --> 00:45:03,080 Speaker 1: and can kind of with the combined data suss out 732 00:45:03,120 --> 00:45:06,000 Speaker 1: whether or not you're walking upstairs or you're going up 733 00:45:06,239 --> 00:45:09,200 Speaker 1: a pathway. But it turns out it's not an exact science. 734 00:45:09,520 --> 00:45:11,920 Speaker 1: So for example, yesterday it told me that I climbed 735 00:45:12,000 --> 00:45:15,600 Speaker 1: seventy five flights of stairs. I definitely did not climb 736 00:45:15,600 --> 00:45:18,399 Speaker 1: seventy five flights of stairs yesterday, but I did walk 737 00:45:18,520 --> 00:45:22,840 Speaker 1: up a lot of hills. So that that's the uh, 738 00:45:22,880 --> 00:45:26,439 Speaker 1: you know, kind of subtlety that it can't quite tell 739 00:45:26,480 --> 00:45:31,320 Speaker 1: the difference between If you were to map fitbit data 740 00:45:31,400 --> 00:45:34,719 Speaker 1: against a map, like literally pair a map with the 741 00:45:34,719 --> 00:45:38,160 Speaker 1: fitbit data in a way for it to take into 742 00:45:38,200 --> 00:45:41,359 Speaker 1: account the geography, maybe then it would say, all right, 743 00:45:41,360 --> 00:45:44,160 Speaker 1: well you didn't walk up seventy f five flights of stairs, 744 00:45:44,160 --> 00:45:46,640 Speaker 1: but you did climb this amount of elevation in this 745 00:45:46,680 --> 00:45:52,480 Speaker 1: amount of time. Later, still, fitbit introduced some heart rate 746 00:45:52,600 --> 00:45:55,080 Speaker 1: monitors in some of its products, and you might want 747 00:45:55,080 --> 00:45:57,480 Speaker 1: to know how does that work? For example, the one 748 00:45:57,480 --> 00:46:00,359 Speaker 1: I have as a charge too, it's got heart ray 749 00:46:00,400 --> 00:46:02,759 Speaker 1: monitor on it. So how does this thing that I 750 00:46:02,800 --> 00:46:07,839 Speaker 1: wear on my wrist tell how frequently my heartbeats? All right? 751 00:46:07,920 --> 00:46:11,680 Speaker 1: So it does this through Oh, good grief, this is 752 00:46:11,719 --> 00:46:15,480 Speaker 1: gonna be a slaughter, all right. It does this through 753 00:46:15,520 --> 00:46:23,320 Speaker 1: a process called photo plethism graphy, also known as PPG, 754 00:46:24,760 --> 00:46:26,200 Speaker 1: which is how I'm going to refer to it for 755 00:46:26,239 --> 00:46:28,200 Speaker 1: the rest of this discussion, because I think I might 756 00:46:28,239 --> 00:46:31,440 Speaker 1: be able to say photo flip, photo flip this ma 757 00:46:31,680 --> 00:46:35,239 Speaker 1: graphy correctly twice in my entire life, and uh, I 758 00:46:35,280 --> 00:46:39,200 Speaker 1: think I just did so. Game over man. Alright. So, 759 00:46:39,320 --> 00:46:42,440 Speaker 1: human blood, as I'm sure most of you are aware, 760 00:46:43,040 --> 00:46:47,840 Speaker 1: is red, right well, red stuff reflects red light and 761 00:46:47,960 --> 00:46:52,200 Speaker 1: it absorbs green light really well. So anything that's red 762 00:46:52,200 --> 00:46:55,279 Speaker 1: gets reflected off of red stuff, anything that's green gets 763 00:46:55,280 --> 00:46:59,040 Speaker 1: absorbed by red stuff. So devices like the fitbit charged 764 00:46:59,080 --> 00:47:02,840 Speaker 1: to pair a couple of light ometers that are pulsing 765 00:47:02,880 --> 00:47:08,080 Speaker 1: green light with a sensor that detects reflected green light, 766 00:47:09,040 --> 00:47:11,279 Speaker 1: and that's how it's able to tell how much light 767 00:47:11,480 --> 00:47:16,359 Speaker 1: is being reflected or absorbed by your blood. So it's 768 00:47:16,360 --> 00:47:21,160 Speaker 1: positioned over little blood veins in your arm, and whenever 769 00:47:21,520 --> 00:47:23,640 Speaker 1: it detects that a lot of light is being absorbed, 770 00:47:24,040 --> 00:47:28,080 Speaker 1: it's saying, oh, blood is flowing through the vein right now. 771 00:47:28,640 --> 00:47:31,279 Speaker 1: Whenever it detects a lot of light is being reflected, 772 00:47:31,320 --> 00:47:35,279 Speaker 1: it says, oh, blood is not flowing through that vein 773 00:47:35,400 --> 00:47:39,839 Speaker 1: right now. And by counting the number of times that 774 00:47:39,960 --> 00:47:44,040 Speaker 1: this absorption and reflection pattern goes within a minute, it 775 00:47:44,120 --> 00:47:46,879 Speaker 1: gives you your heart rate. That's how it works. It's 776 00:47:46,920 --> 00:47:51,000 Speaker 1: kind of cool. It's not full proof to detect heartbeats 777 00:47:51,000 --> 00:47:53,920 Speaker 1: this way. Advice has to be fairly secure against the skin. 778 00:47:54,920 --> 00:47:56,920 Speaker 1: So when you exercise, you tend to move around a lot. 779 00:47:56,960 --> 00:48:00,480 Speaker 1: At least that's what I'm lead to understand. And uh, 780 00:48:00,560 --> 00:48:03,040 Speaker 1: I'm someone who walks a lot, but i haven't really 781 00:48:03,719 --> 00:48:07,360 Speaker 1: jumped into that full exercise schedule, so I'm only speaking 782 00:48:07,360 --> 00:48:09,600 Speaker 1: from second hand experience at this point. But if you're 783 00:48:09,640 --> 00:48:12,440 Speaker 1: doing a lot of vigorous weightlifting or running or something. 784 00:48:12,480 --> 00:48:15,320 Speaker 1: A wrist mounted activity tracker is probably going to slide 785 00:48:15,320 --> 00:48:18,160 Speaker 1: around a lot, and that means it's more difficult to 786 00:48:18,200 --> 00:48:22,000 Speaker 1: get an accurate reading on the heart rate UM and 787 00:48:22,040 --> 00:48:24,919 Speaker 1: that actually has caused some real issues. It's actually could 788 00:48:24,920 --> 00:48:28,919 Speaker 1: be potentially dangerous. Uh. Some people really push themselves very 789 00:48:28,960 --> 00:48:31,319 Speaker 1: hard when they're working out. They're trying to get their 790 00:48:31,360 --> 00:48:34,920 Speaker 1: heart at a peak level for a certain amount of time. UM. 791 00:48:35,120 --> 00:48:37,799 Speaker 1: Particularly people who are really trying to push their performance, 792 00:48:38,200 --> 00:48:39,719 Speaker 1: and they need to know if their heart rate is 793 00:48:39,760 --> 00:48:42,839 Speaker 1: exceeding safe parameters. If it's at peak for too long, 794 00:48:42,920 --> 00:48:47,520 Speaker 1: they could actually suffer some serious health problems. So Fitbit 795 00:48:47,600 --> 00:48:50,239 Speaker 1: and other activity company tracker companies have come under fire 796 00:48:50,360 --> 00:48:54,279 Speaker 1: from some healthcare professionals who have said, your marketing a 797 00:48:54,360 --> 00:48:57,920 Speaker 1: product with certain claims that could lead someone to believe 798 00:48:58,000 --> 00:49:03,040 Speaker 1: they have a level of vision akin to a medical device, 799 00:49:03,600 --> 00:49:07,280 Speaker 1: but you haven't submitted your products to the kind of testing, 800 00:49:07,320 --> 00:49:10,399 Speaker 1: the rigorous testing that medical devices have to go through 801 00:49:10,760 --> 00:49:14,320 Speaker 1: in order to be certified as being that kind of accurate. 802 00:49:14,880 --> 00:49:18,480 Speaker 1: And uh. Again it becomes this this war of words 803 00:49:18,840 --> 00:49:21,960 Speaker 1: with activity tracker and company saying this is something to 804 00:49:22,040 --> 00:49:26,960 Speaker 1: help people with fitness issues, but it's not marketed as 805 00:49:26,960 --> 00:49:29,719 Speaker 1: a medical device, and the medical industry saying yeah, but 806 00:49:29,760 --> 00:49:31,839 Speaker 1: people are kind of treating it that way. So there's 807 00:49:31,840 --> 00:49:34,480 Speaker 1: a level of responsibility you need to take, and it's 808 00:49:34,520 --> 00:49:38,239 Speaker 1: kind of a back and forth. Now. By measuring a 809 00:49:38,320 --> 00:49:40,680 Speaker 1: user's heart rate, fitbit can also make a little bit 810 00:49:40,760 --> 00:49:43,239 Speaker 1: more of an educated guess as to how many calories 811 00:49:43,320 --> 00:49:46,200 Speaker 1: that person is burning in a day. And you probably 812 00:49:46,200 --> 00:49:49,000 Speaker 1: heard about the various ranges of heart rates that indicate 813 00:49:49,000 --> 00:49:52,560 Speaker 1: whether you're in a fat burning mode which is slightly elevated, 814 00:49:53,000 --> 00:49:55,759 Speaker 1: or if you're in a cardio vascular exercise mode, which 815 00:49:55,800 --> 00:49:58,800 Speaker 1: is a range beyond that, or if you're in peak mode, 816 00:49:58,840 --> 00:50:01,719 Speaker 1: which is that other level I was talking about, or 817 00:50:01,760 --> 00:50:04,480 Speaker 1: if you're just resting. And this is actually a pretty 818 00:50:04,480 --> 00:50:07,640 Speaker 1: tricky area itself, even outside of the technology sphere, there 819 00:50:07,640 --> 00:50:09,839 Speaker 1: are a lot of people who argue exactly where that 820 00:50:09,960 --> 00:50:13,200 Speaker 1: range should be and how accurate it is, or whether 821 00:50:13,239 --> 00:50:15,279 Speaker 1: it's accurate at all, or what does it mean or 822 00:50:15,480 --> 00:50:18,080 Speaker 1: is it meaningful? Uh, And I'm not going to get 823 00:50:18,080 --> 00:50:19,680 Speaker 1: into that because it doesn't really have anything to do 824 00:50:19,760 --> 00:50:21,759 Speaker 1: with the technology, but it does show that this is 825 00:50:21,800 --> 00:50:25,319 Speaker 1: another area where there's a lot of disagreement about what 826 00:50:25,600 --> 00:50:29,800 Speaker 1: is the actual right way to go forward. But Fitbit 827 00:50:29,840 --> 00:50:33,320 Speaker 1: will combine information from all these different accelerometers and altimeter 828 00:50:33,440 --> 00:50:35,719 Speaker 1: and heart rate sensors in order to give you an 829 00:50:35,760 --> 00:50:38,120 Speaker 1: idea of how many calories you have burned throughout the day, 830 00:50:38,600 --> 00:50:45,399 Speaker 1: even though that might not be absolutely accurate. Now we're 831 00:50:45,400 --> 00:50:48,240 Speaker 1: gonna talk a little bit more about the company side 832 00:50:48,239 --> 00:50:51,000 Speaker 1: of Fitbit, now that we've covered the technology side quite 833 00:50:51,000 --> 00:50:53,759 Speaker 1: a bit in just a second. But first let's take 834 00:50:53,760 --> 00:51:04,160 Speaker 1: another quick break to thank our sponsor. All Right, let's 835 00:51:04,200 --> 00:51:06,879 Speaker 1: go back to talk about the company a little bit 836 00:51:07,160 --> 00:51:12,040 Speaker 1: and how Fitbit has performed through all of this. So 837 00:51:12,239 --> 00:51:15,960 Speaker 1: shortly after Fitbit took off, activity trackers became a huge 838 00:51:16,360 --> 00:51:20,040 Speaker 1: deal in the electronics industry, and Fitbit enjoyed a great 839 00:51:20,040 --> 00:51:23,200 Speaker 1: amount of success. Very early on, they focused on creating 840 00:51:23,239 --> 00:51:26,520 Speaker 1: those products that we're feeling, filling a niche between like 841 00:51:27,600 --> 00:51:31,120 Speaker 1: and two hundred dollars. Really like the hundred and thirty 842 00:51:31,640 --> 00:51:35,360 Speaker 1: and fifty dollar range was their their playground, and that 843 00:51:35,440 --> 00:51:39,800 Speaker 1: also meant that they were avoiding the problems of creating 844 00:51:40,280 --> 00:51:45,839 Speaker 1: higher priced luxury items that that some electronics fans were 845 00:51:45,840 --> 00:51:49,359 Speaker 1: balking at. They also decided early that they were not 846 00:51:49,400 --> 00:51:52,520 Speaker 1: going to get into smart watches right away, which ended 847 00:51:52,600 --> 00:51:54,719 Speaker 1: up being a smart decision because a lot of people 848 00:51:54,760 --> 00:51:58,160 Speaker 1: were out there trying to create smart watches and no 849 00:51:58,239 --> 00:52:00,319 Speaker 1: one was really sure what a smart watch would be 850 00:52:00,400 --> 00:52:02,840 Speaker 1: or what should do apart from tell the time, and 851 00:52:02,840 --> 00:52:04,480 Speaker 1: I'm sure some of them were even wondering if it 852 00:52:04,520 --> 00:52:08,960 Speaker 1: should do that. Now, Fitbit did include stuff like a 853 00:52:09,120 --> 00:52:13,360 Speaker 1: watch and some of its models, so there were models 854 00:52:13,440 --> 00:52:18,600 Speaker 1: after the Fitbit tracker that had a clock element to them, 855 00:52:18,719 --> 00:52:21,719 Speaker 1: but you would say that it was a clock on 856 00:52:21,800 --> 00:52:24,920 Speaker 1: an activity tracker, not that it was a watch that 857 00:52:25,080 --> 00:52:32,440 Speaker 1: also tracked activity. So very different approach, not something that 858 00:52:32,480 --> 00:52:36,600 Speaker 1: the smart watch companies were really going after. Then they 859 00:52:36,640 --> 00:52:39,440 Speaker 1: started adding other features, like you could get notifications on 860 00:52:39,640 --> 00:52:42,600 Speaker 1: certain Fitbit devices, so when you paired it with a phone, 861 00:52:42,840 --> 00:52:44,960 Speaker 1: if a notification came through on your phone, you might 862 00:52:45,000 --> 00:52:47,600 Speaker 1: get an alert on your Fitbit. So you might miss 863 00:52:47,640 --> 00:52:49,440 Speaker 1: it if your phones in your pocket, but then your 864 00:52:49,440 --> 00:52:52,120 Speaker 1: wrist vibrates and you take a look and you see, oh, 865 00:52:52,320 --> 00:52:54,840 Speaker 1: someone's texting me, or I just got an email or 866 00:52:54,880 --> 00:52:57,600 Speaker 1: whatever it might be, or I've got a calendar event 867 00:52:57,680 --> 00:53:03,160 Speaker 1: coming up that I should pay attention to. Then Fitbit 868 00:53:03,320 --> 00:53:06,279 Speaker 1: eventually did release a smart watch. They released it in 869 00:53:07,960 --> 00:53:11,680 Speaker 1: and it's called the Fitbit Blaze, and that was really 870 00:53:11,680 --> 00:53:14,200 Speaker 1: the first attempt to Fitbit to take aim at the 871 00:53:14,239 --> 00:53:17,240 Speaker 1: smart watch industry. But at that point they were already saying, 872 00:53:17,960 --> 00:53:20,839 Speaker 1: we wanna wait to see how other companies do it 873 00:53:21,719 --> 00:53:24,640 Speaker 1: and see what's working and what's not working before we 874 00:53:24,719 --> 00:53:28,360 Speaker 1: attempt to do it ourselves, because right now everyone's arguing 875 00:53:28,400 --> 00:53:31,120 Speaker 1: over what a smart watch should even be, So why 876 00:53:31,160 --> 00:53:33,839 Speaker 1: would we make something if we're not even sure that 877 00:53:33,840 --> 00:53:37,359 Speaker 1: that particular form factor is going to ever work out. 878 00:53:38,480 --> 00:53:41,319 Speaker 1: So they did launch the Blaze last year. I know 879 00:53:41,560 --> 00:53:43,719 Speaker 1: that they were very proud of it, but kind of 880 00:53:43,719 --> 00:53:47,239 Speaker 1: surprised that the market didn't immediately respond in a very 881 00:53:47,239 --> 00:53:51,360 Speaker 1: positive way. The reviews were pretty good, but the market 882 00:53:51,400 --> 00:53:54,480 Speaker 1: itself didn't respond in a very enthusiastic way, and that 883 00:53:54,840 --> 00:53:58,600 Speaker 1: frustrated people over at Fitbit. And I think largely that's 884 00:53:58,600 --> 00:54:01,880 Speaker 1: again because even as could sumers, we aren't really sure 885 00:54:01,920 --> 00:54:04,879 Speaker 1: what a smart watch should be, Like, what is the 886 00:54:04,920 --> 00:54:06,960 Speaker 1: thing about a smart watch that's going to make it 887 00:54:07,000 --> 00:54:11,080 Speaker 1: so useful that you absolutely have to have it unless 888 00:54:11,080 --> 00:54:14,080 Speaker 1: you're an iPhone Apple fan? In which case you probably 889 00:54:14,080 --> 00:54:18,320 Speaker 1: buy an Apple smart watch because it had Apple on it. 890 00:54:18,680 --> 00:54:27,080 Speaker 1: Burn back. In two thousand, Fitbit launched its initial public offering. 891 00:54:27,120 --> 00:54:29,520 Speaker 1: It's I p O. In other words, this is the 892 00:54:29,560 --> 00:54:34,719 Speaker 1: process where a privately held company switches over to a 893 00:54:34,760 --> 00:54:39,160 Speaker 1: publicly traded company. It's where you issue stock and people 894 00:54:39,200 --> 00:54:43,080 Speaker 1: can go and buy stock in your company. Before the 895 00:54:43,120 --> 00:54:45,880 Speaker 1: stocks went on the market, before they were going to 896 00:54:45,880 --> 00:54:50,640 Speaker 1: be traded, they were initially valued at twenty dollars a share. 897 00:54:52,320 --> 00:54:54,880 Speaker 1: That was before trading began, but once trading began, the 898 00:54:54,960 --> 00:54:58,240 Speaker 1: value actually shot up very quickly. The actual opening price 899 00:54:58,320 --> 00:55:02,400 Speaker 1: was thirty dollars forty sense. The company ended up getting 900 00:55:02,400 --> 00:55:06,960 Speaker 1: evaluation of four point one billion dollars. You essentially multiply 901 00:55:07,040 --> 00:55:10,000 Speaker 1: the number of shares by the share price. That gives 902 00:55:10,040 --> 00:55:12,680 Speaker 1: you a rough idea of the valuation four point one 903 00:55:13,120 --> 00:55:18,479 Speaker 1: billion dollars. James Park received the honor of being named 904 00:55:18,520 --> 00:55:22,840 Speaker 1: one of Fortune magazines forty under forty in two thousand fifteen. 905 00:55:23,400 --> 00:55:27,360 Speaker 1: He was thirty nine at the time, a year younger 906 00:55:27,360 --> 00:55:31,200 Speaker 1: than me. I can't lie to you, this one hurts 907 00:55:31,200 --> 00:55:34,680 Speaker 1: a bit. I'm sure that in two thousand fourteen I 908 00:55:34,800 --> 00:55:38,919 Speaker 1: was like, seriously considered for inclusion in the forty under forty, 909 00:55:38,960 --> 00:55:42,000 Speaker 1: but I probably missed it by that much. But seriously, though, 910 00:55:42,320 --> 00:55:45,480 Speaker 1: it was another indicator that park In Freedman had been 911 00:55:46,080 --> 00:55:50,640 Speaker 1: on the very tip of the spear that was activity trackers, 912 00:55:50,680 --> 00:55:54,680 Speaker 1: that they had led that charge well. And this was 913 00:55:54,840 --> 00:55:57,800 Speaker 1: also around the time that activity trackers began to dominate 914 00:55:58,040 --> 00:56:02,319 Speaker 1: entire sections of the room floor at ce s every 915 00:56:02,360 --> 00:56:06,640 Speaker 1: year there's an entire area that's just activity trackers, and 916 00:56:06,920 --> 00:56:11,319 Speaker 1: it's enormous. Traditional companies and startups alike, we're getting into 917 00:56:11,320 --> 00:56:14,560 Speaker 1: the game, and the space became really highly competitive. Fit 918 00:56:14,640 --> 00:56:17,120 Speaker 1: that was benefiting from the fact that they had been 919 00:56:17,120 --> 00:56:20,640 Speaker 1: in the market since it first started. But it's also 920 00:56:20,640 --> 00:56:22,719 Speaker 1: important to mention Fitbit. It's not like they were the 921 00:56:22,760 --> 00:56:25,800 Speaker 1: first activity tracker of all time, but they were early 922 00:56:25,960 --> 00:56:29,600 Speaker 1: enough and popular enough to become kind of the defining 923 00:56:29,719 --> 00:56:33,879 Speaker 1: name in the space for a lot of people. Now 924 00:56:33,880 --> 00:56:37,520 Speaker 1: there's another challenge that all activity companies have to face. 925 00:56:38,320 --> 00:56:40,479 Speaker 1: Not only is there a lot of competition out there, 926 00:56:41,080 --> 00:56:43,520 Speaker 1: but there's also the problem of convincing customers to buy 927 00:56:43,520 --> 00:56:47,280 Speaker 1: an activity tracker if they already own an activity tracker. 928 00:56:48,080 --> 00:56:52,400 Speaker 1: So it's not just competition, but also market saturation. Activity 929 00:56:52,440 --> 00:56:55,000 Speaker 1: trackers are designed to last a pretty good long while. 930 00:56:55,120 --> 00:56:57,719 Speaker 1: If they died out super fast, people would be very 931 00:56:57,760 --> 00:57:01,319 Speaker 1: irritated with them. So think about, you know, that whole 932 00:57:01,360 --> 00:57:05,759 Speaker 1: planned obsolescence idea, That strategy of let's make something that 933 00:57:05,840 --> 00:57:08,120 Speaker 1: within a couple of years you absolutely have to replace 934 00:57:08,200 --> 00:57:11,279 Speaker 1: because it will be obsolete, doesn't really work so well 935 00:57:11,280 --> 00:57:13,759 Speaker 1: with activity trackers. A lot of people feel that as 936 00:57:13,800 --> 00:57:16,720 Speaker 1: long as it's still working, that's good enough for them. 937 00:57:16,880 --> 00:57:19,920 Speaker 1: So that means it gets harder and harder to sell 938 00:57:19,960 --> 00:57:23,000 Speaker 1: more of your products. There are more people selling, so 939 00:57:23,080 --> 00:57:25,240 Speaker 1: you've got a lot of competition, and a lot of 940 00:57:25,280 --> 00:57:28,919 Speaker 1: your your target customers already owned one, so it's hard 941 00:57:28,960 --> 00:57:31,760 Speaker 1: to commence them to go and buy a new one. 942 00:57:33,120 --> 00:57:37,000 Speaker 1: That means that and make it even more complicated. Not 943 00:57:37,080 --> 00:57:40,520 Speaker 1: just activity trackers, smart watches too. Right, if you've gone 944 00:57:40,600 --> 00:57:43,000 Speaker 1: in and you've bought a smart watch that happens to 945 00:57:43,040 --> 00:57:46,040 Speaker 1: have some activity tracking capabilities as well as being a 946 00:57:46,040 --> 00:57:49,440 Speaker 1: smart watch, that's even less reason for you to go 947 00:57:49,480 --> 00:57:52,360 Speaker 1: out and buy another activity tracker. So not only was 948 00:57:52,400 --> 00:57:55,680 Speaker 1: Fitbit competing against other activity trackers, but also all the 949 00:57:55,760 --> 00:57:58,600 Speaker 1: smart watch companies that were building in those let's even 950 00:57:58,640 --> 00:58:03,040 Speaker 1: go even more complicated. Smartphones now can act as activity trackers. 951 00:58:03,440 --> 00:58:05,840 Speaker 1: A lot of smartphones have a built in app that 952 00:58:05,920 --> 00:58:09,160 Speaker 1: will count steps and maybe even do things like map 953 00:58:09,200 --> 00:58:12,440 Speaker 1: how many steps you've made against a physical map, or 954 00:58:12,760 --> 00:58:15,680 Speaker 1: tell you how much you've changed in altitude across the 955 00:58:15,760 --> 00:58:19,480 Speaker 1: day based upon where you went. All of these different 956 00:58:19,520 --> 00:58:23,760 Speaker 1: things are direct competitors or indirect competitors with activity trackers, 957 00:58:23,760 --> 00:58:27,640 Speaker 1: which meant that Fitbit was facing more and more pressures 958 00:58:27,880 --> 00:58:30,960 Speaker 1: from outside of its own company and had to figure 959 00:58:30,960 --> 00:58:35,200 Speaker 1: out ways to remain relevant and compelling to customers. Part 960 00:58:35,200 --> 00:58:39,040 Speaker 1: of that was again aiming at people who didn't want 961 00:58:39,080 --> 00:58:41,960 Speaker 1: to spend four hundred dollars five hundred dollars for a 962 00:58:42,000 --> 00:58:44,760 Speaker 1: smart watch. Maybe they'd spend a hundred dollars or a 963 00:58:44,800 --> 00:58:47,720 Speaker 1: hundred thirty dollars for an activity tracker, especially one that 964 00:58:47,800 --> 00:58:50,800 Speaker 1: had enough features in it to set it apart from 965 00:58:50,800 --> 00:58:55,800 Speaker 1: just a predominter. But it does mean that you're constantly 966 00:58:55,840 --> 00:58:58,760 Speaker 1: having to reinvent yourself and find ways of making products 967 00:58:58,760 --> 00:59:03,000 Speaker 1: that are interesting and use full and intuitive, and not 968 00:59:03,120 --> 00:59:06,680 Speaker 1: everything has gone smoothly. In two thousand and fourteen, the 969 00:59:06,680 --> 00:59:09,800 Speaker 1: company had to issue a recall of the fitbit Force, 970 00:59:10,200 --> 00:59:13,480 Speaker 1: which was one of the activity trackers that that you 971 00:59:13,520 --> 00:59:16,840 Speaker 1: would wear using a wristband. In fact, most of fitbits 972 00:59:16,880 --> 00:59:19,320 Speaker 1: trackers use a wristband, but not all of them. This 973 00:59:19,400 --> 00:59:22,040 Speaker 1: was one of them. There were quite a few people 974 00:59:22,120 --> 00:59:26,760 Speaker 1: who reported that they were having problems like skin issues 975 00:59:27,480 --> 00:59:29,720 Speaker 1: after wearing the wrist band, that it was causing them 976 00:59:29,760 --> 00:59:33,280 Speaker 1: to break out in a rash or sometimes worse, into blisters. 977 00:59:33,760 --> 00:59:37,600 Speaker 1: In fact, it got so bad that, according to some reports, 978 00:59:37,760 --> 00:59:41,520 Speaker 1: more than nine thousand people said they were having issues, 979 00:59:41,520 --> 00:59:43,640 Speaker 1: with more than two fifty of them saying that it 980 00:59:43,680 --> 00:59:47,680 Speaker 1: was blistering. And so eventually the company issued a recall 981 00:59:47,880 --> 00:59:50,640 Speaker 1: and discontinued the product and refunded people their money for 982 00:59:50,760 --> 00:59:54,760 Speaker 1: buying it because of these these problems. Now, the likely 983 00:59:54,800 --> 00:59:59,160 Speaker 1: reason behind all this was that the wrist band had 984 00:59:59,240 --> 01:00:01,200 Speaker 1: some components and that they were made out of nickel, 985 01:00:01,800 --> 01:00:04,240 Speaker 1: and a lot of people have an allergy of skin 986 01:00:04,280 --> 01:00:09,040 Speaker 1: allergy to nickel. Uh they can contract dermatitis if their 987 01:00:09,080 --> 01:00:12,439 Speaker 1: skin is in contact with nickel for too long. I'm 988 01:00:12,440 --> 01:00:14,760 Speaker 1: one of those people, and I didn't find out through 989 01:00:14,800 --> 01:00:17,480 Speaker 1: an activity tracker. Actually found out because I had a 990 01:00:17,520 --> 01:00:21,640 Speaker 1: silver plated ring and the the thing that the silver 991 01:00:21,840 --> 01:00:24,320 Speaker 1: was plating was a nickel core, right, it was a 992 01:00:24,400 --> 01:00:27,080 Speaker 1: ring with a nickel core but silver plating, And eventually 993 01:00:27,080 --> 01:00:29,680 Speaker 1: the silver on the inside the ring wore off enough 994 01:00:30,160 --> 01:00:33,120 Speaker 1: where the nickel was making contact with my skin and 995 01:00:33,160 --> 01:00:35,360 Speaker 1: it was a wide band ring and I started having 996 01:00:35,400 --> 01:00:38,000 Speaker 1: this terrible reaction. So if I had bought one of 997 01:00:38,040 --> 01:00:39,959 Speaker 1: those fitbits, I would have been one of the people 998 01:00:40,000 --> 01:00:44,080 Speaker 1: who had that that same issue. That skin irritation. Uh, 999 01:00:44,360 --> 01:00:47,200 Speaker 1: is not fun. And that did not do the company 1000 01:00:47,240 --> 01:00:49,800 Speaker 1: any favors. Although the fact that they did issue a 1001 01:00:49,880 --> 01:00:53,640 Speaker 1: recall was the right thing to do, um, but it 1002 01:00:53,680 --> 01:00:56,280 Speaker 1: was it was not a great publicity move to have 1003 01:00:56,520 --> 01:00:59,400 Speaker 1: something that gives your customers blisters all over their wrists. 1004 01:01:00,840 --> 01:01:03,320 Speaker 1: And then there's also been some legal battles. There was 1005 01:01:03,560 --> 01:01:06,400 Speaker 1: a couple of legal battles with Jawbone, which also makes 1006 01:01:06,440 --> 01:01:11,520 Speaker 1: activity trackers, and jaw Bone at one point alleged that 1007 01:01:11,640 --> 01:01:16,360 Speaker 1: fitbit had stole stolen corporate secrets from jaw Bone, that 1008 01:01:16,480 --> 01:01:21,680 Speaker 1: they were stealing patented work, and so they sued Fitbit. 1009 01:01:22,480 --> 01:01:25,960 Speaker 1: Later on, a court actually overturned the patents in question, 1010 01:01:26,080 --> 01:01:29,520 Speaker 1: so there was no foundation anymore for the lawsuit because 1011 01:01:30,480 --> 01:01:35,160 Speaker 1: the thing that had been a patented idea, the patented invention. 1012 01:01:35,760 --> 01:01:39,280 Speaker 1: The patent was invalidated, so there was no longer any 1013 01:01:39,400 --> 01:01:45,560 Speaker 1: legal claim for that. That particular lawsuit faded away. In October, 1014 01:01:46,600 --> 01:01:51,040 Speaker 1: James Park appeared on the program Mad Money to say 1015 01:01:51,040 --> 01:01:53,280 Speaker 1: the company as a whole was going to change direction 1016 01:01:53,320 --> 01:01:55,400 Speaker 1: and it was going to transition from what he called 1017 01:01:55,680 --> 01:02:01,080 Speaker 1: a consumer electronics company to a digital healthcare company. And 1018 01:02:01,120 --> 01:02:03,320 Speaker 1: he went on to say that the social aspect of 1019 01:02:03,360 --> 01:02:06,120 Speaker 1: what the company was doing would become more important in 1020 01:02:06,160 --> 01:02:08,560 Speaker 1: the future. Now, this may have been in response to 1021 01:02:08,600 --> 01:02:11,320 Speaker 1: a really rough year on the market in twenty sixteen. 1022 01:02:11,680 --> 01:02:17,520 Speaker 1: Fitbit saw their stock price drop steadily throughout the entire year. 1023 01:02:18,040 --> 01:02:21,040 Speaker 1: Uh the high price for a Fitbit stock over the 1024 01:02:21,120 --> 01:02:24,680 Speaker 1: last fifty two weeks was eighteen dollars forty three cents. 1025 01:02:24,720 --> 01:02:27,400 Speaker 1: Remember it was initially valued at twenty dollars before it 1026 01:02:27,440 --> 01:02:31,080 Speaker 1: opened on trading, back when they first went public. It 1027 01:02:31,160 --> 01:02:34,640 Speaker 1: went up to thirty dollars forty cents the that day, 1028 01:02:35,920 --> 01:02:39,920 Speaker 1: and now it's down to less than much less than 1029 01:02:39,960 --> 01:02:45,280 Speaker 1: that actually today, which is March. I checked the stock 1030 01:02:45,320 --> 01:02:47,120 Speaker 1: price and when I checked it, it was five dollars 1031 01:02:47,120 --> 01:02:51,360 Speaker 1: and thirty seven cents, So pretty massive fall off in 1032 01:02:51,440 --> 01:02:55,560 Speaker 1: stock price. The appearance on Mad Money was interesting and 1033 01:02:55,560 --> 01:02:58,640 Speaker 1: that Park said that Fitbit could help employers save money 1034 01:02:58,640 --> 01:03:01,880 Speaker 1: on providing healthcare plans for employees, and he cited a 1035 01:03:01,920 --> 01:03:05,760 Speaker 1: third party study that suggested employees who opted into a 1036 01:03:05,800 --> 01:03:11,680 Speaker 1: Fitbit wellness plan would cost employers twenty less than employees 1037 01:03:11,720 --> 01:03:16,120 Speaker 1: who did not enter the Fitbit wellness plan. So perhaps 1038 01:03:16,200 --> 01:03:18,680 Speaker 1: the future of fitbit is really in designing corporate wellness 1039 01:03:18,680 --> 01:03:21,760 Speaker 1: initiatives and the hardware will just kind of supplement that. 1040 01:03:22,960 --> 01:03:26,400 Speaker 1: And they've also been on acquisition tear recently. You may 1041 01:03:27,320 --> 01:03:33,400 Speaker 1: say that, uh that Fitbit essentially rated Pebble, because it 1042 01:03:33,440 --> 01:03:39,760 Speaker 1: wasn't so it wasn't like a standard acquisition. It was 1043 01:03:39,840 --> 01:03:43,400 Speaker 1: acquiring very specific parts of Pebble and taking just the 1044 01:03:43,440 --> 01:03:46,520 Speaker 1: parts they wanted. Pebble, by the way, in case you 1045 01:03:46,560 --> 01:03:48,240 Speaker 1: don't know, it's a company that was known for making 1046 01:03:48,240 --> 01:03:53,120 Speaker 1: relatively simple but interesting smart watches and it got started 1047 01:03:53,120 --> 01:03:57,600 Speaker 1: originally as a crowdfunding campaign. And the smart watches use 1048 01:03:57,640 --> 01:04:01,960 Speaker 1: an e paper display so that they're very low power. Uh, 1049 01:04:02,000 --> 01:04:05,640 Speaker 1: and they were able to give you notifications from your 1050 01:04:05,640 --> 01:04:11,040 Speaker 1: phone that kind of stuff. Fitbit bought out Pebbles software 1051 01:04:11,080 --> 01:04:15,360 Speaker 1: assets for less than forty million dollars according to Bloomberg 1052 01:04:15,400 --> 01:04:19,360 Speaker 1: Technology Now sadly, Pebble as a company actually had more 1053 01:04:19,400 --> 01:04:23,160 Speaker 1: than forty million dollars in debts, so they didn't even 1054 01:04:23,160 --> 01:04:24,960 Speaker 1: get as much as they needed in order to pay 1055 01:04:24,960 --> 01:04:27,880 Speaker 1: off their debts in this case, and Pebble had found 1056 01:04:27,920 --> 01:04:31,760 Speaker 1: that it was very difficult to thrive in a crowded marketplace, 1057 01:04:32,440 --> 01:04:34,520 Speaker 1: and it didn't help that you still have a significant 1058 01:04:34,520 --> 01:04:37,320 Speaker 1: population of people who aren't even convinced that smart watches 1059 01:04:37,480 --> 01:04:40,960 Speaker 1: are an interesting thing to buy in the first place. So, 1060 01:04:41,000 --> 01:04:44,160 Speaker 1: according to Bloomberg, Fitbit sent job offers to about fort 1061 01:04:44,880 --> 01:04:49,120 Speaker 1: of Pebble's workforce, meaning did not get an offer to 1062 01:04:49,160 --> 01:04:52,760 Speaker 1: work at Fitbit. And as someone who owns a Kickstarter 1063 01:04:53,040 --> 01:04:56,520 Speaker 1: edition Pebble watch, this whole thing made me very sad, 1064 01:04:56,960 --> 01:04:59,920 Speaker 1: not just because my watch would no longer be supported, 1065 01:05:00,480 --> 01:05:05,360 Speaker 1: but I really thought Pebble was something special, and there 1066 01:05:05,400 --> 01:05:07,760 Speaker 1: were a lot of folks who were eagerly anticipating Pebble's 1067 01:05:07,800 --> 01:05:09,880 Speaker 1: next product, and they were very dismayed to learn it 1068 01:05:09,880 --> 01:05:14,360 Speaker 1: will never come. But such as business. In January, Fitbit 1069 01:05:14,440 --> 01:05:18,720 Speaker 1: acquired a another smart watch group, a company that had 1070 01:05:18,760 --> 01:05:23,000 Speaker 1: started up just in March sixteen called Vector, so it 1071 01:05:23,040 --> 01:05:25,680 Speaker 1: wasn't even a year old when Fitbit came in and 1072 01:05:25,680 --> 01:05:28,920 Speaker 1: acquired it. Vector's market was to create what they called 1073 01:05:29,320 --> 01:05:33,920 Speaker 1: affordable luxury smart watches, so their designs kind of harkened 1074 01:05:33,920 --> 01:05:37,920 Speaker 1: back to classic European luxury watches, but at a lower cost, 1075 01:05:38,840 --> 01:05:43,320 Speaker 1: and they're smart watches, not your typical quartz crystal action watches. 1076 01:05:44,040 --> 01:05:46,440 Speaker 1: And like Pebble, the acquisition appears to have been a 1077 01:05:46,480 --> 01:05:50,000 Speaker 1: bid for the software developer talent. The founder of Vector, 1078 01:05:50,120 --> 01:05:53,280 Speaker 1: named Andre Petis, said as much, said that the company 1079 01:05:53,400 --> 01:05:57,920 Speaker 1: was acquired for this software platform and for its design team. 1080 01:05:57,960 --> 01:06:00,480 Speaker 1: So does that mean that Fitbit will soon produce luxury 1081 01:06:00,560 --> 01:06:05,240 Speaker 1: smart watches? Probably not. They may set all of these 1082 01:06:05,280 --> 01:06:08,320 Speaker 1: assets to work on creating those digital health care solutions 1083 01:06:08,320 --> 01:06:11,000 Speaker 1: that I mentioned earlier, and I suspect will continue to 1084 01:06:11,000 --> 01:06:15,560 Speaker 1: see Fitbit produce activity trackers and sensors, but that these 1085 01:06:15,600 --> 01:06:19,200 Speaker 1: will fit into a larger package of healthcare solutions, so 1086 01:06:19,280 --> 01:06:22,320 Speaker 1: that way Fitbit can continue to set itself apart from 1087 01:06:22,360 --> 01:06:25,840 Speaker 1: all the competing activity trackers companies out there. They're not 1088 01:06:26,000 --> 01:06:32,000 Speaker 1: just selling activity trackers, they're selling health itself. That's me 1089 01:06:32,680 --> 01:06:36,920 Speaker 1: saying that not Fitbit, and who knows, maybe in ten 1090 01:06:36,960 --> 01:06:40,280 Speaker 1: we will see some luxury smart watch activity trackers from Fitbit, 1091 01:06:40,680 --> 01:06:43,840 Speaker 1: and maybe they'll become the must have fashion accessory ofen. 1092 01:06:43,920 --> 01:06:47,200 Speaker 1: I wouldn't be shocked to see it happen, and I 1093 01:06:47,320 --> 01:06:49,560 Speaker 1: might even save up for one because I lack I 1094 01:06:49,680 --> 01:06:53,560 Speaker 1: lack looking all flash while tracking my steps. But we'll see. 1095 01:06:54,600 --> 01:06:56,320 Speaker 1: And that's all I've got on Fitbit right now. I 1096 01:06:56,320 --> 01:06:58,880 Speaker 1: could have talked a little bit more about some other elements, 1097 01:06:58,920 --> 01:07:03,520 Speaker 1: like there was a tie where Apple sold Fitbit products 1098 01:07:03,520 --> 01:07:06,200 Speaker 1: in its Apple Store, and then there was a very 1099 01:07:06,240 --> 01:07:08,880 Speaker 1: famous time when they said they would stop doing that. 1100 01:07:09,560 --> 01:07:13,000 Speaker 1: But you know, honestly, that story is not as interesting 1101 01:07:13,080 --> 01:07:16,360 Speaker 1: as it first sounds when you hear the connotation there. 1102 01:07:16,600 --> 01:07:18,960 Speaker 1: And besides, I gotta save something for future episodes now 1103 01:07:18,960 --> 01:07:21,520 Speaker 1: that I'm going to twice a week again. So I 1104 01:07:21,520 --> 01:07:24,760 Speaker 1: hope you guys enjoyed this glimpse into the company Fitbit 1105 01:07:24,880 --> 01:07:27,680 Speaker 1: and the explanation of how that technology works.
