1 00:00:04,519 --> 00:00:11,760 Speaker 1: With technology with hook stuff from how stuff dot com everything. 2 00:00:14,360 --> 00:00:17,880 Speaker 1: Hey there, everyone, and welcome to tech Stuff. I'm Jonathan's 3 00:00:17,880 --> 00:00:21,160 Speaker 1: Trickland and on Lauren Vocbum and we're gonna track your 4 00:00:21,160 --> 00:00:25,040 Speaker 1: activity with activity trackers. That's what we're talking about today. 5 00:00:25,040 --> 00:00:28,240 Speaker 1: We're talking about various devices that allow you to see 6 00:00:28,320 --> 00:00:32,400 Speaker 1: how much activity you've you've you've generated over a certain 7 00:00:32,440 --> 00:00:35,040 Speaker 1: amount of time, and sometimes it helps you figure out 8 00:00:35,159 --> 00:00:38,360 Speaker 1: how many calories you've burned or how well you've been sleeping. 9 00:00:38,880 --> 00:00:41,599 Speaker 1: We want to talk about what these devices are, what 10 00:00:41,640 --> 00:00:43,839 Speaker 1: they do, how they do it, and whether or not 11 00:00:43,880 --> 00:00:46,599 Speaker 1: they're actually effective if you want to do something like 12 00:00:46,760 --> 00:00:49,360 Speaker 1: lose weight or get fit. Yeah. Just I mean, you know, 13 00:00:49,400 --> 00:00:51,159 Speaker 1: not that that many people are interested in that kind 14 00:00:51,159 --> 00:00:54,680 Speaker 1: of thing, you know, Yeah, there's like maybe two right, Okay, 15 00:00:54,680 --> 00:00:56,520 Speaker 1: So the last few times I've gone to C E 16 00:00:56,840 --> 00:00:58,960 Speaker 1: S I have noticed really it was I think it 17 00:00:59,000 --> 00:01:02,920 Speaker 1: was two years ago where that it was dramatically apparent 18 00:01:03,040 --> 00:01:06,399 Speaker 1: that fitness tracking and activity tracking is a real thing. 19 00:01:06,480 --> 00:01:09,160 Speaker 1: I mean, it's it's huge, huge, booming industry. Yeah. Well, 20 00:01:09,200 --> 00:01:11,960 Speaker 1: I mean, you know, as as between circuitry getting smaller 21 00:01:11,959 --> 00:01:16,759 Speaker 1: and uh sinking, technology improving and the software improving, and 22 00:01:16,840 --> 00:01:18,800 Speaker 1: just all of these things have been coming together to 23 00:01:19,040 --> 00:01:24,000 Speaker 1: create these smaller, sleeker, you know, better devices that can 24 00:01:24,160 --> 00:01:27,800 Speaker 1: really help people out things that are things like interoperability 25 00:01:27,880 --> 00:01:31,880 Speaker 1: to where it can interact with computers or smartphones. Not 26 00:01:31,880 --> 00:01:35,160 Speaker 1: not every device does that. Let's be clear about that. 27 00:01:35,200 --> 00:01:37,000 Speaker 1: There are a lot of devices out there that have 28 00:01:37,160 --> 00:01:39,760 Speaker 1: kind of a limited use like that. Maybe they just 29 00:01:39,800 --> 00:01:42,279 Speaker 1: sink with a computer, or maybe it's just a standalone device, 30 00:01:42,520 --> 00:01:45,560 Speaker 1: but a lot of them do sync up with more 31 00:01:45,600 --> 00:01:47,360 Speaker 1: than one device. You could do it with a smartphone 32 00:01:47,400 --> 00:01:50,840 Speaker 1: application or or a computer or other things as well, 33 00:01:51,120 --> 00:01:53,320 Speaker 1: and they'll let you They'll let you up port port 34 00:01:53,400 --> 00:01:55,960 Speaker 1: whatever data you record into different apps, so that if, 35 00:01:55,960 --> 00:01:58,080 Speaker 1: for example, you're into this kind of thing and you 36 00:01:58,120 --> 00:02:00,480 Speaker 1: have a favorite app you can you can use that 37 00:02:00,520 --> 00:02:03,760 Speaker 1: one to crunch your numbers rather than whatever other proprietary 38 00:02:03,800 --> 00:02:06,480 Speaker 1: thing they have created. Right, Right, So this gives you 39 00:02:06,520 --> 00:02:09,840 Speaker 1: a chance to, uh, to really keep a good look, 40 00:02:09,919 --> 00:02:11,840 Speaker 1: you know, get a really good look at how much 41 00:02:11,880 --> 00:02:15,640 Speaker 1: activity you are you have throughout a given amount of time, 42 00:02:15,680 --> 00:02:18,200 Speaker 1: like a week or a day. So you might say, 43 00:02:18,240 --> 00:02:20,600 Speaker 1: all right, I want to set a goal for myself 44 00:02:20,720 --> 00:02:24,080 Speaker 1: and this device will help me measure up against that 45 00:02:24,120 --> 00:02:26,560 Speaker 1: goal and decide, you know, am I am I meeting 46 00:02:26,560 --> 00:02:29,120 Speaker 1: my goal? Do I need to uh to crank up 47 00:02:29,160 --> 00:02:31,240 Speaker 1: the activity? Do I need to maybe you know, do 48 00:02:31,360 --> 00:02:34,240 Speaker 1: a three mile jog in the morning in order to 49 00:02:34,320 --> 00:02:36,760 Speaker 1: hit what my goals are? Do I need to UM 50 00:02:37,080 --> 00:02:40,280 Speaker 1: to scale back or for for for hardcore trainers, am 51 00:02:40,280 --> 00:02:42,760 Speaker 1: I running my heart rate too hard? Yeah? Yeah, So 52 00:02:43,360 --> 00:02:45,519 Speaker 1: it all depends on what device you have, whether or 53 00:02:45,560 --> 00:02:48,120 Speaker 1: not you can actually do these things, because, like we said, 54 00:02:48,120 --> 00:02:52,920 Speaker 1: not every device does everything. In fact, depending upon what 55 00:02:53,000 --> 00:02:55,359 Speaker 1: you want, that's going to really guide your choices when 56 00:02:55,400 --> 00:02:58,400 Speaker 1: it comes to picking an activity tracker. If you're interested 57 00:02:58,440 --> 00:03:00,600 Speaker 1: in something like that, absolutely and is um there's a 58 00:03:00,600 --> 00:03:02,800 Speaker 1: lot of really terrific reviews out there on the internet. 59 00:03:02,919 --> 00:03:05,800 Speaker 1: We'll mentioned at least one good site to go to 60 00:03:05,960 --> 00:03:08,800 Speaker 1: later on in the podcast. Yeah, there's I came across 61 00:03:08,880 --> 00:03:11,040 Speaker 1: lots and lots of them. And it's interesting too because 62 00:03:11,080 --> 00:03:14,959 Speaker 1: you can see where the different preferences come into play, 63 00:03:15,000 --> 00:03:18,480 Speaker 1: because one reviewer might say, well, you know, X is 64 00:03:18,520 --> 00:03:22,080 Speaker 1: the best activity tracker because it does things this way, 65 00:03:22,160 --> 00:03:23,679 Speaker 1: and someone else will say, no, no no, no, why is 66 00:03:23,720 --> 00:03:25,959 Speaker 1: the best activity tracker because it does things in this 67 00:03:26,040 --> 00:03:28,520 Speaker 1: other way, and it's just because it appeals to that 68 00:03:28,560 --> 00:03:32,760 Speaker 1: particular person a very personal choice. Right So, so that's 69 00:03:32,760 --> 00:03:34,480 Speaker 1: one thing you can get you can walk away with 70 00:03:34,639 --> 00:03:36,440 Speaker 1: right now, is that we're not gonna at the end 71 00:03:36,440 --> 00:03:38,440 Speaker 1: of this podcast. It's not like we're gonna say the 72 00:03:38,480 --> 00:03:41,480 Speaker 1: best activity tracker is blah blah blah, because it all 73 00:03:41,560 --> 00:03:44,920 Speaker 1: depends on what you want to get out of it now. Frankly, 74 00:03:45,040 --> 00:03:47,320 Speaker 1: I think if you are looking at one of these things, 75 00:03:47,360 --> 00:03:48,720 Speaker 1: the thing you really want to get out of it 76 00:03:48,840 --> 00:03:52,280 Speaker 1: is is making sure that you are living a healthy lifestyle. 77 00:03:53,280 --> 00:03:55,200 Speaker 1: And most of the ones that are on the market 78 00:03:55,280 --> 00:03:58,360 Speaker 1: right now will help you do that, depending on how 79 00:03:58,480 --> 00:04:01,800 Speaker 1: you use it. It's it's not magic device that automatically 80 00:04:01,800 --> 00:04:05,680 Speaker 1: turns you into a fit pro athlete right now. Now. 81 00:04:05,720 --> 00:04:07,280 Speaker 1: You have to you have to have your own personal 82 00:04:07,280 --> 00:04:11,600 Speaker 1: sense of motivation about exercising first. Probably obtaining a fitness 83 00:04:11,640 --> 00:04:13,720 Speaker 1: tracker is going to be one of the steps that 84 00:04:13,760 --> 00:04:17,200 Speaker 1: you're you know, carrying out in this motivation um and 85 00:04:17,200 --> 00:04:21,040 Speaker 1: and study studies have shown um that that that just 86 00:04:21,240 --> 00:04:23,640 Speaker 1: mindfulness about this kind of thing can really help you 87 00:04:23,680 --> 00:04:28,280 Speaker 1: out from lots lots of different corners of health and 88 00:04:28,320 --> 00:04:32,400 Speaker 1: fitness when when you are given the power to track 89 00:04:32,480 --> 00:04:34,520 Speaker 1: your own data and to kind of take it into 90 00:04:34,560 --> 00:04:36,559 Speaker 1: your own hands like that, maybe gamify at a tiny 91 00:04:36,560 --> 00:04:40,240 Speaker 1: bit um you, it really helps you out right. There's 92 00:04:40,279 --> 00:04:43,840 Speaker 1: an expert, her name's Dina Bravada. I'm sure you ran 93 00:04:43,920 --> 00:04:46,960 Speaker 1: across her name several times as well, because it's all 94 00:04:46,960 --> 00:04:51,479 Speaker 1: over the place in the research on activity tracking, and 95 00:04:51,800 --> 00:04:55,159 Speaker 1: she has said that there there is a bit of 96 00:04:55,200 --> 00:04:58,880 Speaker 1: a bias that's present with activity trackers in the sense 97 00:04:58,960 --> 00:05:02,080 Speaker 1: of the people who who are interested in them. She 98 00:05:02,160 --> 00:05:05,240 Speaker 1: says that here's a quote. Often those kind of programs 99 00:05:05,240 --> 00:05:08,160 Speaker 1: have been criticized because they attract people who are already 100 00:05:08,160 --> 00:05:11,400 Speaker 1: physically active. In general, there are two categories of people 101 00:05:11,440 --> 00:05:13,920 Speaker 1: who use these trackers, those who are told to wear 102 00:05:13,960 --> 00:05:16,679 Speaker 1: them by a doctor because of an underlying health problem 103 00:05:16,920 --> 00:05:18,840 Speaker 1: and those who are really active and just get a 104 00:05:18,920 --> 00:05:21,720 Speaker 1: kick out of knowing their data. Now, none of that 105 00:05:21,960 --> 00:05:26,160 Speaker 1: is a smack against these activity trackers and whether or 106 00:05:26,240 --> 00:05:29,240 Speaker 1: not they are effective in what they do. She is 107 00:05:29,279 --> 00:05:32,080 Speaker 1: simply saying that this is the person side of that equation, 108 00:05:32,400 --> 00:05:35,599 Speaker 1: not the technology side of that equation. So let's assume 109 00:05:35,680 --> 00:05:37,720 Speaker 1: that at least some of you guys out there listening 110 00:05:37,760 --> 00:05:40,920 Speaker 1: are very much interested in this kind of stuff, and 111 00:05:41,440 --> 00:05:43,640 Speaker 1: you are either interested in just knowing how they work 112 00:05:43,640 --> 00:05:45,880 Speaker 1: in general, or you're actually thinking, hey, I would kind 113 00:05:45,880 --> 00:05:49,200 Speaker 1: of like to look into one of these How do 114 00:05:49,279 --> 00:05:53,120 Speaker 1: they track activity? What exactly is being tracked? And what 115 00:05:53,240 --> 00:05:56,000 Speaker 1: other features might I be interested in if I want 116 00:05:56,040 --> 00:05:58,479 Speaker 1: to get one of these things myself. So I thought 117 00:05:58,480 --> 00:06:00,799 Speaker 1: we'd talked a little bit about some of the basic 118 00:06:00,920 --> 00:06:05,720 Speaker 1: technologies that you find inside some of these trackers, all right, 119 00:06:05,760 --> 00:06:09,560 Speaker 1: because these little these little bitty watch sized or bracelet 120 00:06:09,640 --> 00:06:12,960 Speaker 1: sized or clips clips, you know, you have very very 121 00:06:13,000 --> 00:06:16,160 Speaker 1: small devices these days. You can pack a lot of 122 00:06:17,080 --> 00:06:21,040 Speaker 1: tracking devices into them. Yeah, the sensors that are available 123 00:06:21,120 --> 00:06:23,560 Speaker 1: now really boggle the mind. And like we said, I 124 00:06:23,600 --> 00:06:25,400 Speaker 1: don't think there is a device out there that has 125 00:06:25,480 --> 00:06:27,719 Speaker 1: every single version of what we're about to talk about. 126 00:06:27,760 --> 00:06:29,800 Speaker 1: But they I have not seen one. Yeah, but but 127 00:06:29,920 --> 00:06:31,839 Speaker 1: many of them have several some of them only have 128 00:06:32,200 --> 00:06:34,880 Speaker 1: one or two some and it may be that the 129 00:06:34,880 --> 00:06:37,760 Speaker 1: way that they're packaged is very attractive, but they but 130 00:06:37,960 --> 00:06:41,960 Speaker 1: from a technological point of view, they are comparatively simple. 131 00:06:42,640 --> 00:06:46,320 Speaker 1: But I think one very basic technology we can talk 132 00:06:46,360 --> 00:06:48,960 Speaker 1: about that you can find and in fact, some people 133 00:06:48,960 --> 00:06:50,840 Speaker 1: will argue that this is really all you need if 134 00:06:50,880 --> 00:06:54,440 Speaker 1: you just want to track some basic activity. Is a predometer, right, 135 00:06:54,520 --> 00:06:56,960 Speaker 1: and these have been mechanical predometers. I believe it's been 136 00:06:56,960 --> 00:07:01,040 Speaker 1: around since the nineteen sixties. And they hypothetic like this 137 00:07:01,120 --> 00:07:04,520 Speaker 1: is this is tenuous, tenuous reportage. But but some people 138 00:07:04,560 --> 00:07:07,200 Speaker 1: say that the da Vinci or Thomas Jefferson came up 139 00:07:07,200 --> 00:07:10,360 Speaker 1: with the idea many many moons ago. Yeah, that's a 140 00:07:10,560 --> 00:07:13,960 Speaker 1: pretty big spread in years if I know my history. 141 00:07:14,000 --> 00:07:18,280 Speaker 1: But yeah, and I do. But yeah, a podometer today, 142 00:07:18,920 --> 00:07:21,760 Speaker 1: it takes a pretty basic form. Usually you have some 143 00:07:21,840 --> 00:07:24,160 Speaker 1: sort of display that's going to tell you how many 144 00:07:24,200 --> 00:07:26,600 Speaker 1: steps you have taken. That's what a podometer does. It's 145 00:07:26,600 --> 00:07:28,760 Speaker 1: supposed to measure how many steps you take. So how 146 00:07:28,760 --> 00:07:32,160 Speaker 1: does it do that. It's essentially counting the number of 147 00:07:32,160 --> 00:07:35,679 Speaker 1: times your foot makes impact with the ground. And really 148 00:07:35,760 --> 00:07:39,240 Speaker 1: that means it's just measuring various shaking of your body. 149 00:07:39,320 --> 00:07:42,000 Speaker 1: So if you are in a car and you're on 150 00:07:42,040 --> 00:07:44,760 Speaker 1: a particularly bumpy road, it's going to start registering that 151 00:07:44,800 --> 00:07:48,840 Speaker 1: as footsteps if it's particularly bumpy, right, or or if 152 00:07:48,840 --> 00:07:50,560 Speaker 1: you hold it in your hand and sway your arm 153 00:07:50,600 --> 00:07:53,080 Speaker 1: back and forth, you would totally fool the device, right, 154 00:07:53,200 --> 00:07:56,560 Speaker 1: not that I know that from prior get Fit corporate 155 00:07:56,800 --> 00:07:59,800 Speaker 1: UM programs that I have cheated a tiny bit on right, Uh, 156 00:08:00,480 --> 00:08:03,400 Speaker 1: if you're not benefiting anyone at that point, let's let's 157 00:08:03,400 --> 00:08:07,160 Speaker 1: stop the cheating. Hey, Lauren, aren't you the team captain 158 00:08:07,200 --> 00:08:12,280 Speaker 1: of our own departmental cheating. I was demonstrating to people 159 00:08:12,320 --> 00:08:15,840 Speaker 1: how the device worked, and I was accused of using 160 00:08:15,880 --> 00:08:19,440 Speaker 1: that as a way of boosting your numbers. All right, 161 00:08:19,480 --> 00:08:21,360 Speaker 1: team captain, Now I've learned a little more about you. 162 00:08:21,480 --> 00:08:24,720 Speaker 1: So anyway, what's what's going on here is inside the 163 00:08:24,720 --> 00:08:29,400 Speaker 1: pedometer you have a a system that essentially forms a switch. 164 00:08:29,680 --> 00:08:32,320 Speaker 1: All right, You've got you've got a weight, and when 165 00:08:32,320 --> 00:08:36,560 Speaker 1: that weight moves it can make a connection that closes 166 00:08:36,600 --> 00:08:38,920 Speaker 1: a switch and counts as a step. And then when 167 00:08:38,960 --> 00:08:42,160 Speaker 1: it moves away that and hits it again, that counts 168 00:08:42,200 --> 00:08:45,320 Speaker 1: as another step. So every time this weight disconnects and 169 00:08:45,320 --> 00:08:50,720 Speaker 1: then reconnects with a contact, a step is registered. And uh, 170 00:08:50,960 --> 00:08:52,440 Speaker 1: you know, it used to be that these were pretty 171 00:08:52,480 --> 00:08:55,360 Speaker 1: big mechanical things where you had a weight suspended on 172 00:08:55,720 --> 00:08:58,720 Speaker 1: like a spring or a pendulum or a small ball 173 00:08:58,760 --> 00:09:00,840 Speaker 1: that could roll back and forth, a cross a tiny track. 174 00:09:01,040 --> 00:09:03,880 Speaker 1: Right now, we're talking about things that are on the 175 00:09:03,880 --> 00:09:08,200 Speaker 1: the micro structure level. But it's still this basic mechanical 176 00:09:08,280 --> 00:09:12,320 Speaker 1: motion of making a contact, breaking a contact, and that 177 00:09:12,400 --> 00:09:14,439 Speaker 1: every time you do that break is what counts is 178 00:09:14,480 --> 00:09:17,680 Speaker 1: a step. Yeah, so uh, it's still still the same 179 00:09:17,720 --> 00:09:21,240 Speaker 1: mechanical approach. It's just now it's much much, much, much 180 00:09:21,280 --> 00:09:23,680 Speaker 1: smaller than what it used to be back in the 181 00:09:23,679 --> 00:09:28,320 Speaker 1: sixties or earlier. If we are to believe that some 182 00:09:28,400 --> 00:09:32,240 Speaker 1: of our our genius ancestors came up with this idea, 183 00:09:32,400 --> 00:09:35,760 Speaker 1: it was probably Tesla, yeah, and it always ends up 184 00:09:35,760 --> 00:09:39,240 Speaker 1: being Tesla, although his probably would also bring down an airplane. 185 00:09:39,720 --> 00:09:43,560 Speaker 1: So uh. Anyway, the old predometers, if you would actually 186 00:09:43,600 --> 00:09:45,000 Speaker 1: pick one up and shake it, you might hear a 187 00:09:45,040 --> 00:09:48,280 Speaker 1: clicking noise, and that's the little switch that's inside it. Again, 188 00:09:48,320 --> 00:09:50,400 Speaker 1: it might be that little ball if it's using that 189 00:09:50,440 --> 00:09:54,280 Speaker 1: particular kind of technology. The newer ones, again, are all 190 00:09:54,360 --> 00:09:57,240 Speaker 1: chip based. They don't have those little those They don't 191 00:09:57,240 --> 00:09:59,520 Speaker 1: have things large enough to make that kind of clicking 192 00:09:59,520 --> 00:10:02,200 Speaker 1: noise unless you've been shaking it way too hard, in 193 00:10:02,200 --> 00:10:04,280 Speaker 1: which case something is probably loose and it may not 194 00:10:04,360 --> 00:10:07,959 Speaker 1: be working at all. Anymore. But anyway, that's your very 195 00:10:07,960 --> 00:10:12,360 Speaker 1: basic pedometer. So it's not terribly accurate in the sense 196 00:10:12,440 --> 00:10:16,520 Speaker 1: that it can't it can't distinguish between different kinds of 197 00:10:16,559 --> 00:10:18,679 Speaker 1: impact and say, oh, well that was definitely a step 198 00:10:18,840 --> 00:10:21,920 Speaker 1: versus that was just a bump, right, um. But they 199 00:10:22,320 --> 00:10:25,120 Speaker 1: are getting a little bit more technologically advanced in that. 200 00:10:25,120 --> 00:10:28,880 Speaker 1: Originally you had to use the counter and combine that 201 00:10:28,920 --> 00:10:31,400 Speaker 1: with a calculation of how long each of your steps 202 00:10:31,400 --> 00:10:33,560 Speaker 1: were in order to calculate distance. These days, they can 203 00:10:33,559 --> 00:10:36,319 Speaker 1: do that for you with onboard computers. Sure. Oh so 204 00:10:36,360 --> 00:10:39,080 Speaker 1: instead of saying like, oh, my stride is this many 205 00:10:39,120 --> 00:10:42,199 Speaker 1: inches long, therefore this many steps and having to get 206 00:10:42,200 --> 00:10:44,680 Speaker 1: a little bit of math. By the way, I said inches, 207 00:10:44,720 --> 00:10:47,680 Speaker 1: and I would say miles because I live in America 208 00:10:47,720 --> 00:10:50,120 Speaker 1: and that's what we do. But centimeters meters that kind 209 00:10:50,120 --> 00:10:53,000 Speaker 1: of thing, right, it would It does the math depending 210 00:10:53,000 --> 00:10:57,360 Speaker 1: on what scale you're using. The more advanced version of 211 00:10:57,400 --> 00:11:02,560 Speaker 1: this sort of approach is the accelerometer. Now, an accelerometer 212 00:11:02,600 --> 00:11:04,840 Speaker 1: is different. It's not got a little switch that's just 213 00:11:05,720 --> 00:11:10,360 Speaker 1: registering a change. Yeah, it's not just like that was 214 00:11:10,400 --> 00:11:14,880 Speaker 1: a shake. It's actually detecting changes in velocity. Uh. Now, 215 00:11:15,000 --> 00:11:20,400 Speaker 1: velocity is speed plus direction. So if you alter that velocity, 216 00:11:20,440 --> 00:11:24,840 Speaker 1: then you are talking about an accelerating force. So, for example, 217 00:11:24,880 --> 00:11:27,679 Speaker 1: when you start, when you start from a standstill and 218 00:11:27,720 --> 00:11:31,800 Speaker 1: you start moving into a run, that's accelerating. You're accelerating 219 00:11:31,800 --> 00:11:33,640 Speaker 1: into a run. Now, once you hit top speed, you 220 00:11:33,640 --> 00:11:36,040 Speaker 1: are no longer accelerating. You may be maintaining a speed. 221 00:11:36,400 --> 00:11:40,720 Speaker 1: But accelerat arometers are all meant to detect these changes 222 00:11:40,760 --> 00:11:44,960 Speaker 1: in velocity. And you've got two basic categories of accelerometers. 223 00:11:44,960 --> 00:11:47,480 Speaker 1: There are many types of accelerometer rometers, but they fall 224 00:11:47,520 --> 00:11:51,880 Speaker 1: into two basic categories. They're static accelerometers. Now, these measure 225 00:11:51,960 --> 00:11:58,880 Speaker 1: a static uh form of acceleration. For instance, gravity, Gravity 226 00:11:59,200 --> 00:12:02,920 Speaker 1: is static, it's not changing when you are on the 227 00:12:02,960 --> 00:12:05,079 Speaker 1: surface of the Earth. It's going to remain the same. 228 00:12:05,559 --> 00:12:09,520 Speaker 1: And so you might wonder why would you need a 229 00:12:09,520 --> 00:12:13,880 Speaker 1: stack accelerometer. It's so that you can determine the rotation 230 00:12:14,040 --> 00:12:16,800 Speaker 1: of a device in respect to the surface of the Earth. 231 00:12:17,160 --> 00:12:20,480 Speaker 1: Very important for something like a smartphone, where you are 232 00:12:20,520 --> 00:12:22,600 Speaker 1: holding the smartphone, you move it from portrait to landscape, 233 00:12:23,600 --> 00:12:27,800 Speaker 1: the static accelerometer is what tells it, oh, the the 234 00:12:28,240 --> 00:12:31,680 Speaker 1: the attitude of this phone has changed not that you're 235 00:12:31,760 --> 00:12:34,439 Speaker 1: giving off attitude. Necessarily, you might be texting I don't 236 00:12:34,800 --> 00:12:38,000 Speaker 1: I usually amy, this is fair, but and rather the 237 00:12:38,080 --> 00:12:40,560 Speaker 1: position in relative to the surface of the earth. So 238 00:12:40,600 --> 00:12:43,040 Speaker 1: if you were to turn it into the landscape mode, 239 00:12:43,240 --> 00:12:48,400 Speaker 1: the screen would would change to reflect that. That's why 240 00:12:48,360 --> 00:12:53,440 Speaker 1: a stack accelerometer is useful. For dynamic accelerometers, they measure 241 00:12:53,600 --> 00:12:57,440 Speaker 1: changes in motion of the accelerometer itself. So the accelerometer 242 00:12:57,520 --> 00:12:59,800 Speaker 1: is part of the larger device. So this is too 243 00:13:00,120 --> 00:13:03,240 Speaker 1: measure the changes in acceleration of that device, not in 244 00:13:03,320 --> 00:13:05,800 Speaker 1: respect to the ground, but just within that device itself. 245 00:13:06,120 --> 00:13:10,320 Speaker 1: So you might have both types in a fitness tracker. 246 00:13:10,440 --> 00:13:12,480 Speaker 1: If the fitness tracker has some sort of screen that 247 00:13:12,520 --> 00:13:16,080 Speaker 1: will rotate depending upon how you're holding your arm. Let's 248 00:13:16,080 --> 00:13:18,400 Speaker 1: say it's a it's a screen that's on a wristband 249 00:13:18,480 --> 00:13:20,959 Speaker 1: or something that's like a watch, and then it might 250 00:13:20,960 --> 00:13:23,960 Speaker 1: have a stack accelerometer and a dynamic one. The dynamic 251 00:13:23,960 --> 00:13:26,720 Speaker 1: one would be more useful for it to detect changes 252 00:13:26,760 --> 00:13:31,120 Speaker 1: in velocity and thus translate that into motion that the 253 00:13:31,240 --> 00:13:35,319 Speaker 1: user is moving around, and that means that the user 254 00:13:35,480 --> 00:13:39,320 Speaker 1: is burning calories and is there's there's activity going on, 255 00:13:39,400 --> 00:13:42,960 Speaker 1: so that's part of the data that this device will 256 00:13:43,280 --> 00:13:47,839 Speaker 1: gather and analyze to translate that into this is what 257 00:13:47,880 --> 00:13:50,120 Speaker 1: your body is doing right right, and we should we 258 00:13:50,160 --> 00:13:52,720 Speaker 1: should add at this point that UM, that a lot 259 00:13:53,080 --> 00:13:56,079 Speaker 1: of the actual output of data that these devices are 260 00:13:56,120 --> 00:13:59,080 Speaker 1: giving you is not UM. Is not the actual data 261 00:13:59,120 --> 00:14:00,920 Speaker 1: that these sensors are making in a lot of it 262 00:14:01,040 --> 00:14:04,680 Speaker 1: is UM really fancy algorithms. And and thank you to 263 00:14:04,760 --> 00:14:06,719 Speaker 1: Peter on Facebook for writing it and telling me that 264 00:14:06,760 --> 00:14:09,720 Speaker 1: I totally say that wrong sometimes because I do UM. 265 00:14:09,760 --> 00:14:13,360 Speaker 1: You know, it's it's it's approximating more complex technology, or 266 00:14:13,400 --> 00:14:16,960 Speaker 1: it's UM gathering together a bunch of these little tiny 267 00:14:17,080 --> 00:14:20,240 Speaker 1: numbers and figuring out something useful that I can tell 268 00:14:20,320 --> 00:14:23,320 Speaker 1: you in return, exactly taking this raw data and making 269 00:14:23,320 --> 00:14:26,160 Speaker 1: it meaningful to us, because otherwise we really what an 270 00:14:26,200 --> 00:14:29,640 Speaker 1: accelerometer would tell you is how much voltage it was generating, 271 00:14:29,720 --> 00:14:31,960 Speaker 1: which doesn't help us at all. That doesn't that's not 272 00:14:32,080 --> 00:14:35,160 Speaker 1: meaningful to at least it's not meaningful to me, and 273 00:14:35,200 --> 00:14:38,880 Speaker 1: I suspect not to Lauren. Uh. Some of you electricians 274 00:14:38,880 --> 00:14:40,800 Speaker 1: out there might say, no, I totally get it, but 275 00:14:40,880 --> 00:14:42,640 Speaker 1: the rest of us are thinking, no, we need this 276 00:14:42,680 --> 00:14:45,280 Speaker 1: translated into something that makes sense like how many calories 277 00:14:45,280 --> 00:14:46,840 Speaker 1: did I burn or how many steps did I take 278 00:14:46,920 --> 00:14:50,400 Speaker 1: or how far did I go? So that's that's the 279 00:14:50,480 --> 00:14:56,440 Speaker 1: basic uh two kinds of accelerometers. The the types underneath 280 00:14:56,440 --> 00:15:01,000 Speaker 1: those are how they detect these changes in the law city. UH. 281 00:15:01,000 --> 00:15:03,840 Speaker 1: And there's a lot there's there are capacitive ones, there's 282 00:15:03,880 --> 00:15:08,240 Speaker 1: piece of electric, there's pizza resistive, there's magneto resistive, there's 283 00:15:08,280 --> 00:15:11,440 Speaker 1: heat transfer. There's lots of different types. There's some that 284 00:15:11,560 --> 00:15:14,840 Speaker 1: use light. But the one that I think, the type 285 00:15:14,840 --> 00:15:16,960 Speaker 1: that's used the most in electronics as far as I 286 00:15:17,000 --> 00:15:20,680 Speaker 1: can tell, is the capacitive type. And so you might 287 00:15:20,680 --> 00:15:24,720 Speaker 1: wonder how does this work. You've got some micro structures 288 00:15:24,760 --> 00:15:28,240 Speaker 1: within a chip, all right. One of them is you've 289 00:15:28,280 --> 00:15:31,720 Speaker 1: got a housing which is is mounted directly to whatever 290 00:15:31,720 --> 00:15:35,800 Speaker 1: the devices on a substrate. So this housing uh will 291 00:15:35,880 --> 00:15:39,800 Speaker 1: move in uh the same way that the device itself moves. 292 00:15:40,000 --> 00:15:44,120 Speaker 1: It's it's dependent upon that. Then you've got a little 293 00:15:44,280 --> 00:15:49,760 Speaker 1: micro structure inside of it that can move freely uh 294 00:15:49,840 --> 00:15:53,200 Speaker 1: in respect to the housing. So if you were to 295 00:15:53,240 --> 00:15:56,240 Speaker 1: shake the device, the micro structure would lag a little 296 00:15:56,240 --> 00:15:58,400 Speaker 1: bit and then pick up that motion, just as if 297 00:15:58,440 --> 00:16:00,640 Speaker 1: you had a spring with a ball on the end, 298 00:16:00,640 --> 00:16:02,240 Speaker 1: and you started moving the top of the spring and 299 00:16:02,280 --> 00:16:03,720 Speaker 1: then the ball would start to move. It's this whole 300 00:16:03,720 --> 00:16:06,480 Speaker 1: momentum thing that's coming up. You've also got these other 301 00:16:06,520 --> 00:16:09,800 Speaker 1: little bitty structures, these micro structures inside this this tiny 302 00:16:09,840 --> 00:16:12,760 Speaker 1: little chip, and I'm talking about teeny tiny we're we're 303 00:16:12,880 --> 00:16:15,760 Speaker 1: tug on the level of microns. Yeah, these are all 304 00:16:15,800 --> 00:16:19,280 Speaker 1: called a microelectro mechanical systems. Yeah, they're they're so small 305 00:16:19,440 --> 00:16:21,840 Speaker 1: that you have to have an automated system to etch 306 00:16:21,960 --> 00:16:25,520 Speaker 1: them onto chips because there's no human with the precision 307 00:16:26,440 --> 00:16:30,600 Speaker 1: necessary to make these things so super tiny. But as 308 00:16:30,640 --> 00:16:33,560 Speaker 1: the microstructure moves, it starts to move between these plates 309 00:16:33,600 --> 00:16:36,840 Speaker 1: that have capacitance. That changes the capacities. It causes current 310 00:16:36,920 --> 00:16:39,920 Speaker 1: to flow, and measuring the current tells you how much 311 00:16:40,000 --> 00:16:43,560 Speaker 1: this device is moving. And by putting these chips in 312 00:16:43,720 --> 00:16:47,600 Speaker 1: different arrangements within a device, you can track different types 313 00:16:47,640 --> 00:16:50,760 Speaker 1: of movement. Because you can only detect movement along one 314 00:16:50,840 --> 00:16:54,400 Speaker 1: axis with a with a very simple accelerometer. Uh, that 315 00:16:54,440 --> 00:16:58,720 Speaker 1: means that you can detect movement along one line of 316 00:16:59,080 --> 00:17:02,280 Speaker 1: one one vector. Really you can't anything up beyond that. 317 00:17:02,320 --> 00:17:06,440 Speaker 1: It wouldn't detect So let's say left right versus up down. Uh. 318 00:17:06,480 --> 00:17:09,200 Speaker 1: If you had three of these accelerometers or to two 319 00:17:09,240 --> 00:17:12,560 Speaker 1: axis accelerometers that were at right angles to one another, 320 00:17:12,840 --> 00:17:15,240 Speaker 1: you could then detect things like along the x axis, 321 00:17:15,280 --> 00:17:18,199 Speaker 1: the y axis, and the z axis. So three axis 322 00:17:18,240 --> 00:17:21,080 Speaker 1: accelerometers what we call those, and those are that those 323 00:17:21,080 --> 00:17:22,640 Speaker 1: are the popular ones and in all of the new 324 00:17:22,640 --> 00:17:24,520 Speaker 1: devices coming out these days. Yeah, and it's also the 325 00:17:24,560 --> 00:17:27,560 Speaker 1: kind of stuff you find in things like video game controllers. Uh. 326 00:17:27,600 --> 00:17:29,879 Speaker 1: And it's some of them you hear about six axis, 327 00:17:29,920 --> 00:17:33,800 Speaker 1: which is really just getting more specifically precise. Um. Yeah, 328 00:17:33,880 --> 00:17:36,359 Speaker 1: and so this will detect those changes in motion and 329 00:17:36,400 --> 00:17:40,399 Speaker 1: be able to translate that into again meaningful data once 330 00:17:40,440 --> 00:17:44,640 Speaker 1: you run those raw numbers through whatever software you've got. Uh. 331 00:17:44,760 --> 00:17:49,280 Speaker 1: So those are your two basic ways of detecting motion 332 00:17:49,480 --> 00:17:53,080 Speaker 1: from a purely like this device is moving kind of perspective. 333 00:17:53,080 --> 00:17:55,400 Speaker 1: There are other things that will also detect motion, which 334 00:17:55,440 --> 00:17:58,080 Speaker 1: we'll talk about as well in a little bit. Before 335 00:17:58,080 --> 00:17:59,440 Speaker 1: I get to that, though, I do need to say 336 00:17:59,440 --> 00:18:01,720 Speaker 1: there's a couple of are things that are important about accelerometers. 337 00:18:01,760 --> 00:18:05,800 Speaker 1: One is that sensitivity of an accelerometer is extremely important. 338 00:18:06,160 --> 00:18:10,040 Speaker 1: The more sensitive and accelerometer is, then the more it 339 00:18:10,080 --> 00:18:14,080 Speaker 1: will generate a larger charge in our larger change in 340 00:18:14,119 --> 00:18:17,560 Speaker 1: signal rather for a given change and acceleration compared to 341 00:18:17,640 --> 00:18:22,120 Speaker 1: a less sensitive chip. So these bigger changes are easier 342 00:18:22,119 --> 00:18:24,440 Speaker 1: to measure, and that gives the device a better idea 343 00:18:24,440 --> 00:18:28,200 Speaker 1: of the actual changes in acceleration. So, in other words, 344 00:18:28,560 --> 00:18:30,720 Speaker 1: if you if you make it so that these changes 345 00:18:30,760 --> 00:18:33,720 Speaker 1: are are huge, uh, it can really narrow down the 346 00:18:33,720 --> 00:18:36,800 Speaker 1: parameters of what that change means, and it can be 347 00:18:36,920 --> 00:18:40,919 Speaker 1: more precise in thinking this is more likely an actual 348 00:18:41,000 --> 00:18:44,520 Speaker 1: step versus someone just bump their knee on their desk 349 00:18:44,560 --> 00:18:46,920 Speaker 1: and went out, yeah, yeah, that the technology is getting 350 00:18:46,960 --> 00:18:50,160 Speaker 1: a lot better at um weeding out those false positives exactly. 351 00:18:50,440 --> 00:18:52,000 Speaker 1: And then there are other things you've got to keep 352 00:18:52,000 --> 00:18:55,440 Speaker 1: in mind, like what's the maximum swing of your accelerometer 353 00:18:55,760 --> 00:18:58,840 Speaker 1: that's telling you how much force it can measure or 354 00:18:58,840 --> 00:19:01,639 Speaker 1: how much of a change in nextceleration it can measure. Uh, 355 00:19:01,680 --> 00:19:04,439 Speaker 1: this is really more important if you are designing something 356 00:19:04,480 --> 00:19:07,160 Speaker 1: that moves really really fast and comes to really fast 357 00:19:07,200 --> 00:19:10,240 Speaker 1: stops like a jet, not so much with a person, 358 00:19:10,320 --> 00:19:13,439 Speaker 1: because while you feel you might be fast compared to 359 00:19:13,480 --> 00:19:16,440 Speaker 1: other stuff, you're really slow less less fast than the jet. 360 00:19:16,640 --> 00:19:18,600 Speaker 1: And then you have bandwidth, which is how many times 361 00:19:18,600 --> 00:19:22,000 Speaker 1: a second you can take a reliable acceleration reading. Uh. 362 00:19:22,040 --> 00:19:25,240 Speaker 1: And we don't need anything too precise for human activity 363 00:19:25,280 --> 00:19:28,080 Speaker 1: because again we're not moving that quickly. But these are 364 00:19:28,119 --> 00:19:31,680 Speaker 1: things that are important in accelerometers in general. Uh. We've 365 00:19:31,680 --> 00:19:33,560 Speaker 1: got a lot more to talk about as far as 366 00:19:33,600 --> 00:19:37,760 Speaker 1: the sensors go within this these uh, these activity trackers. 367 00:19:37,800 --> 00:19:39,680 Speaker 1: But before we get into that, let's take a quick 368 00:19:39,720 --> 00:19:43,240 Speaker 1: moment to thank our sponsor. Alright, we're back. So, so 369 00:19:43,280 --> 00:19:46,040 Speaker 1: we've talked about accelerometers and photometers, there is one other 370 00:19:46,080 --> 00:19:49,320 Speaker 1: way the device can track whether or not you've moved around, right, 371 00:19:49,359 --> 00:19:53,000 Speaker 1: Because accelerometers are really great fear for example, on a treadmill, Yeah, 372 00:19:53,080 --> 00:19:56,320 Speaker 1: fantastic because it doesn't have to track your location. It 373 00:19:56,400 --> 00:19:59,360 Speaker 1: just has to track what you are doing. But if 374 00:19:59,400 --> 00:20:02,320 Speaker 1: you have a EPs receiver in your activity tracker, and 375 00:20:02,400 --> 00:20:05,560 Speaker 1: some of them do with them, you can actually track 376 00:20:05,920 --> 00:20:09,479 Speaker 1: where you are in relation to I don't know anything 377 00:20:09,520 --> 00:20:11,920 Speaker 1: else on the planet. But these are not so useful 378 00:20:12,280 --> 00:20:14,159 Speaker 1: if you're just running on a treadmill. No, but but 379 00:20:14,200 --> 00:20:17,360 Speaker 1: they are very much more accurate for calculating the distance 380 00:20:17,359 --> 00:20:20,760 Speaker 1: that you have gone, right. Yeah. So GPS in general, 381 00:20:20,840 --> 00:20:24,119 Speaker 1: this Global Positioning system, Uh, what what's going on is 382 00:20:24,119 --> 00:20:27,080 Speaker 1: You've got the satellites that are beaming down information here 383 00:20:27,240 --> 00:20:29,640 Speaker 1: to the planet and network of twenty four of them. Yeah, 384 00:20:30,080 --> 00:20:34,760 Speaker 1: so your GPS receiver receives this these signals from the 385 00:20:34,840 --> 00:20:38,560 Speaker 1: various satellites. Now, each satellite is sending its own unique 386 00:20:38,600 --> 00:20:41,560 Speaker 1: signal down that has essentially a time stamp on it, right, 387 00:20:41,600 --> 00:20:44,800 Speaker 1: and they're all synchronized. Right, So you're getting these different 388 00:20:45,080 --> 00:20:48,280 Speaker 1: signals all at the same time from at least usually 389 00:20:48,320 --> 00:20:52,160 Speaker 1: at least three satellites. Four works best, four works best, 390 00:20:52,480 --> 00:20:54,919 Speaker 1: and and so your device gets these different signals from 391 00:20:54,960 --> 00:20:58,200 Speaker 1: these different satellites, and by measuring how long it took 392 00:20:58,400 --> 00:21:01,399 Speaker 1: the signal from each satellite to get to that uh, 393 00:21:01,440 --> 00:21:05,040 Speaker 1: that device it just compares that against its own its 394 00:21:05,040 --> 00:21:09,080 Speaker 1: own little internal clock. It can tell you where you 395 00:21:09,119 --> 00:21:11,120 Speaker 1: are in the surface of the Earth. Technically you could 396 00:21:11,160 --> 00:21:13,920 Speaker 1: be in one of two places, but that second places 397 00:21:14,080 --> 00:21:17,440 Speaker 1: inside the earth, So we pretty much just say that's 398 00:21:17,520 --> 00:21:20,520 Speaker 1: not it cuts that right out. Yeah, and that this 399 00:21:20,600 --> 00:21:26,120 Speaker 1: was originally military technology, I believe in the seventies and nineties, 400 00:21:26,119 --> 00:21:30,040 Speaker 1: in fact, when when we first started getting consumer access 401 00:21:30,520 --> 00:21:35,600 Speaker 1: to the Global Positioning System, Uh, the accuracy of that 402 00:21:35,640 --> 00:21:38,960 Speaker 1: system for consumers was limited on purpose, right, Yeah. They 403 00:21:39,040 --> 00:21:41,560 Speaker 1: they put limitters into the devices to say like, yeah, 404 00:21:41,680 --> 00:21:43,280 Speaker 1: we don't really want you to know this. Then we 405 00:21:43,320 --> 00:21:48,880 Speaker 1: can say you are somewhere within feet here is here ish. 406 00:21:48,920 --> 00:21:51,920 Speaker 1: But now they're very, very accurate. That's eventually gotten to 407 00:21:51,960 --> 00:21:54,480 Speaker 1: the point where, uh, you know, it's it's just the 408 00:21:54,520 --> 00:21:59,280 Speaker 1: way technology works accurate. Yeah. Yeah, So the GPS receiver 409 00:21:59,400 --> 00:22:02,240 Speaker 1: will act where you are by by taking all this 410 00:22:02,320 --> 00:22:05,200 Speaker 1: information from the satellites and running that through its own 411 00:22:05,200 --> 00:22:09,160 Speaker 1: algorithm and then determining what your location is on the Earth. 412 00:22:09,240 --> 00:22:12,280 Speaker 1: And that way you can do something like, uh, if 413 00:22:12,320 --> 00:22:15,240 Speaker 1: you jog a specific path and you really liked it, 414 00:22:15,280 --> 00:22:17,760 Speaker 1: you can plot it against a map and share it 415 00:22:17,800 --> 00:22:20,160 Speaker 1: with other people. Or you can just you know, see 416 00:22:20,200 --> 00:22:24,720 Speaker 1: how far you went based upon some mapping program. It 417 00:22:24,800 --> 00:22:27,320 Speaker 1: may be that you could compare how far you went 418 00:22:27,440 --> 00:22:30,760 Speaker 1: based from the map compared to whatever the activity tracker says. 419 00:22:30,760 --> 00:22:33,719 Speaker 1: Because some of these have multiple sensors in them, right, 420 00:22:33,760 --> 00:22:35,720 Speaker 1: some of them might have a pedometer or some other 421 00:22:36,320 --> 00:22:38,679 Speaker 1: um means of saying this is how many steps you 422 00:22:38,720 --> 00:22:41,440 Speaker 1: took and use these in conjunction to Yeah, and it's 423 00:22:41,440 --> 00:22:44,520 Speaker 1: funny because I've seen somewhere they do both. They have 424 00:22:44,560 --> 00:22:47,760 Speaker 1: the GPS tracker and they have the pedometer part where 425 00:22:47,760 --> 00:22:49,600 Speaker 1: it tells you how far you went based upon how 426 00:22:49,600 --> 00:22:51,719 Speaker 1: many steps you took, and you can compare the two 427 00:22:51,800 --> 00:22:54,680 Speaker 1: to see how accurate the pedometer is, and in some 428 00:22:54,760 --> 00:22:57,600 Speaker 1: cases it's not so accurate. That's why reading reviews is 429 00:22:57,640 --> 00:22:59,800 Speaker 1: really important because you might you might say, well, if 430 00:22:59,800 --> 00:23:02,240 Speaker 1: I by the predometer, it says I ran four point 431 00:23:02,280 --> 00:23:04,359 Speaker 1: five miles, but when I look at the map it 432 00:23:04,440 --> 00:23:07,159 Speaker 1: says two miles. So yeah, that is a that is 433 00:23:07,200 --> 00:23:09,440 Speaker 1: a large difference. Yeah, there there was actually a review 434 00:23:09,480 --> 00:23:12,440 Speaker 1: I saw that specifically said that. Okay, so those are 435 00:23:12,480 --> 00:23:15,800 Speaker 1: all the various kinds of sensors and technologies that might 436 00:23:16,040 --> 00:23:21,119 Speaker 1: be an activity tracker to motion that you moving around, 437 00:23:21,160 --> 00:23:23,240 Speaker 1: but there are other sensors to right, Yeah, there's a 438 00:23:23,240 --> 00:23:25,080 Speaker 1: whole bunch of them. Um. And these these are all 439 00:23:25,200 --> 00:23:28,719 Speaker 1: the physiological sensors that are going to track things like 440 00:23:28,760 --> 00:23:31,240 Speaker 1: your sweat and your heart rate. And there's been a 441 00:23:31,280 --> 00:23:34,439 Speaker 1: bunch of different things over the years that have that 442 00:23:34,520 --> 00:23:37,600 Speaker 1: have contributed to this. The original heart rate monitor, of course, 443 00:23:37,640 --> 00:23:40,240 Speaker 1: was the electro cardiogram a k a. The e c 444 00:23:40,440 --> 00:23:45,280 Speaker 1: G or e kg UM and that was using electrical 445 00:23:45,280 --> 00:23:48,320 Speaker 1: pickups in an amplifier circuit that would detect the hearts 446 00:23:48,320 --> 00:23:52,040 Speaker 1: electrical impulses through your skin. Um. And you know, when 447 00:23:52,080 --> 00:23:54,120 Speaker 1: when your heart beats, it the way that it does 448 00:23:54,119 --> 00:23:56,720 Speaker 1: it is it generates these pulses, It sends a signal 449 00:23:56,800 --> 00:23:59,000 Speaker 1: out over the nerve pathways on the surface of the 450 00:23:59,040 --> 00:24:02,080 Speaker 1: heart that caused the muscle to contract during each heartbeat. 451 00:24:02,520 --> 00:24:05,399 Speaker 1: And by picking up those electrical signals, you can you 452 00:24:05,440 --> 00:24:09,000 Speaker 1: can track your heartbeat, which is really groovy for um, 453 00:24:09,000 --> 00:24:11,800 Speaker 1: for knowing how hard your body is working, right, because 454 00:24:11,840 --> 00:24:13,800 Speaker 1: I mean, there's there are a lot of things that 455 00:24:13,840 --> 00:24:15,879 Speaker 1: are important when you're exercising, right. It's not just how 456 00:24:15,960 --> 00:24:18,560 Speaker 1: much activity you're doing, how many calories you're burning. If 457 00:24:18,600 --> 00:24:22,280 Speaker 1: you want to have really good cardio workouts, if you 458 00:24:22,280 --> 00:24:24,000 Speaker 1: want to have a good aerobic workout, then you need 459 00:24:24,040 --> 00:24:26,199 Speaker 1: to get to have your heart beating and within a 460 00:24:26,240 --> 00:24:29,960 Speaker 1: certain range for a certain amount of time, right. Uh. 461 00:24:30,000 --> 00:24:32,280 Speaker 1: And and that's I'll get into that a little bit 462 00:24:32,280 --> 00:24:35,320 Speaker 1: more and in the moment, but uh, e c G 463 00:24:35,480 --> 00:24:38,399 Speaker 1: s are a little bit more clunky. Um. Usually they 464 00:24:38,440 --> 00:24:41,680 Speaker 1: work with a chest strap that many runners, especially because 465 00:24:41,720 --> 00:24:44,359 Speaker 1: they're they're they're bouncing around, moving a lot, found very 466 00:24:44,440 --> 00:24:48,960 Speaker 1: uncomfortable to wear. UM. And So a new technology that 467 00:24:49,000 --> 00:24:52,040 Speaker 1: has come out and has become the standard in noninvasive 468 00:24:52,080 --> 00:24:56,399 Speaker 1: heart rate sensor sensory m has been the photo platesmograph 469 00:24:56,720 --> 00:24:59,879 Speaker 1: a k A. The PPG, which may or may not 470 00:25:00,119 --> 00:25:03,000 Speaker 1: be called an optical heart sensor for people who don't 471 00:25:03,000 --> 00:25:05,720 Speaker 1: even want to mess with that entire word. Gotcha, Well, yeah, 472 00:25:05,760 --> 00:25:08,520 Speaker 1: photo would tell me that there's light that's playing a 473 00:25:08,640 --> 00:25:12,960 Speaker 1: role in this somehow. Yes, PPGs bounce light and most 474 00:25:13,080 --> 00:25:15,879 Speaker 1: cases from an l ED in terms of fitness trackers, 475 00:25:15,920 --> 00:25:18,280 Speaker 1: because LEDs are cool bulbs that will not you know, 476 00:25:18,640 --> 00:25:22,000 Speaker 1: burn your skin, burn your skin, which is cool. Um Uh. 477 00:25:22,080 --> 00:25:24,359 Speaker 1: They bounce light through your skin and back to a 478 00:25:24,440 --> 00:25:29,080 Speaker 1: sensor and measure the volume of blood moving through your capillaries. 479 00:25:29,200 --> 00:25:32,040 Speaker 1: And the way this works is that blood absorbs more 480 00:25:32,119 --> 00:25:35,439 Speaker 1: light than it's surrounding tissue. So the less light that 481 00:25:35,480 --> 00:25:38,439 Speaker 1: comes back to the sensor, the greater the volume of 482 00:25:38,440 --> 00:25:41,000 Speaker 1: blood is moving through those capillaries at the time. UM. 483 00:25:41,200 --> 00:25:44,000 Speaker 1: And and this this volume pulses with each heartbeat and 484 00:25:44,040 --> 00:25:47,240 Speaker 1: so by tracking those pulses, a PPG tracks your heart 485 00:25:47,320 --> 00:25:50,520 Speaker 1: rate at rest and during exercise. That's really cool. So 486 00:25:50,560 --> 00:25:52,200 Speaker 1: this is the same sort of thing you get when 487 00:25:52,200 --> 00:25:53,919 Speaker 1: you go into a doctor's office and they have like 488 00:25:53,920 --> 00:25:56,520 Speaker 1: the little finger clamp thing that ends and it uses 489 00:25:56,520 --> 00:25:59,119 Speaker 1: it shines a light onto your fingertip. That is exactly 490 00:25:59,160 --> 00:26:01,639 Speaker 1: what that is. UM. And these these days they have 491 00:26:01,720 --> 00:26:04,560 Speaker 1: become they're they're they're getting a little bit more sensitive 492 00:26:05,640 --> 00:26:08,720 Speaker 1: and UH. And most of them will come in watch 493 00:26:08,800 --> 00:26:10,800 Speaker 1: format and it will be right against the inside of 494 00:26:10,800 --> 00:26:15,280 Speaker 1: your wrist. But you know there they can they can 495 00:26:15,280 --> 00:26:17,880 Speaker 1: be thrown off by the movement of your skin and muscles. UM, 496 00:26:18,280 --> 00:26:21,800 Speaker 1: which happens during workouts pretty frequently in light I would imagine, 497 00:26:21,840 --> 00:26:25,119 Speaker 1: can also cause problems. So some models are pairing a 498 00:26:25,200 --> 00:26:28,680 Speaker 1: PPG with an accelerometer, sometimes a devoted accelerometer, in order 499 00:26:28,720 --> 00:26:33,000 Speaker 1: to compensate for your body's movement. Cool and UH also 500 00:26:33,040 --> 00:26:37,000 Speaker 1: also an interesting point, not entirely relevant fitness trackers, but 501 00:26:37,040 --> 00:26:39,359 Speaker 1: I thought that this was so cool. PPG works differently 502 00:26:39,400 --> 00:26:42,800 Speaker 1: with different wavelengths of light, and so in laboratory and 503 00:26:42,840 --> 00:26:46,560 Speaker 1: hospital situations, infrared radiation can sometimes be used to assess 504 00:26:46,560 --> 00:26:49,639 Speaker 1: blood volume in deep tissue, whereas light in the visible 505 00:26:49,720 --> 00:26:54,000 Speaker 1: range is used in smaller, more commercial devices like these 506 00:26:54,000 --> 00:26:57,240 Speaker 1: fitness trackers. Oh excellent, awesome, So what else? Okay, so 507 00:26:57,280 --> 00:27:01,320 Speaker 1: we've got we've got various ways of tracking the how 508 00:27:01,359 --> 00:27:04,760 Speaker 1: hard or how quickly your heart is beating. We've got 509 00:27:04,840 --> 00:27:07,679 Speaker 1: the idea of position. Are there other ones as well? 510 00:27:07,720 --> 00:27:10,000 Speaker 1: Another great thing to figure out how much you're exerting 511 00:27:10,000 --> 00:27:13,480 Speaker 1: yourself is the galvanic skin response censor, which is a 512 00:27:13,560 --> 00:27:15,919 Speaker 1: really fancy way of saying, how much are you sweating 513 00:27:16,080 --> 00:27:20,080 Speaker 1: right now? Um? It attracts your perspiration by measuring the 514 00:27:20,080 --> 00:27:23,600 Speaker 1: conductivity of your skin. Um, because your skin is a 515 00:27:23,600 --> 00:27:26,680 Speaker 1: pretty good conductor of of of electricity to begin with, 516 00:27:26,720 --> 00:27:29,720 Speaker 1: but when it's wet a k a. When you're sweating, 517 00:27:30,000 --> 00:27:34,760 Speaker 1: it's an even better conductor. So um, so yeah. The 518 00:27:34,760 --> 00:27:37,080 Speaker 1: the the amount that you're perspiring relates to how much 519 00:27:37,119 --> 00:27:40,480 Speaker 1: you're exerting yourself, and so by tracking this this conductivity, 520 00:27:40,600 --> 00:27:45,120 Speaker 1: you can track your exertion. Another great way is through thermometers, 521 00:27:45,280 --> 00:27:49,680 Speaker 1: good old thermometers um, sometimes infra red, sometimes heat flux, 522 00:27:49,840 --> 00:27:55,040 Speaker 1: which just detecting the increase in temperature on you on 523 00:27:55,080 --> 00:27:57,480 Speaker 1: the surface of your skin. Right, yeah, as well as 524 00:27:57,520 --> 00:27:59,760 Speaker 1: I assume there has to be one to detect ambient 525 00:27:59,840 --> 00:28:02,960 Speaker 1: to perature as well. It's usually two paired thermometers. Yeah, 526 00:28:03,000 --> 00:28:07,040 Speaker 1: one tracking your body temperature exactly, one tracking the ambient temperature. 527 00:28:07,040 --> 00:28:10,439 Speaker 1: Because you're a higher body temperature means that you're working harder, 528 00:28:10,680 --> 00:28:15,199 Speaker 1: and you'd also be working harder in a colder ambient temperature. Gotcha, gotcha, 529 00:28:15,440 --> 00:28:19,520 Speaker 1: as opposed to it's just plain hot, right exactly right, 530 00:28:19,920 --> 00:28:23,320 Speaker 1: all right. So these are various trackers and sensors that 531 00:28:23,400 --> 00:28:25,399 Speaker 1: you can find in a lot of the activity trackers 532 00:28:25,400 --> 00:28:27,080 Speaker 1: that are out there. There are other ones as well. 533 00:28:27,160 --> 00:28:29,639 Speaker 1: Some of them are much more specific, and when you 534 00:28:29,680 --> 00:28:31,640 Speaker 1: get down to things like, well how does it track 535 00:28:31,720 --> 00:28:34,560 Speaker 1: your sleep? Well, that's usually things you know, tracking the 536 00:28:34,800 --> 00:28:37,760 Speaker 1: changes in motion. Again, it's usually the accelerometer. If it 537 00:28:37,840 --> 00:28:40,280 Speaker 1: has something that tracks your heart rate, it will be 538 00:28:40,320 --> 00:28:42,480 Speaker 1: tracking your heart rate. Yeah, but it's basically it's usually 539 00:28:42,520 --> 00:28:45,080 Speaker 1: how much you're wiggling around. Yeah. Yeah, So so if 540 00:28:45,120 --> 00:28:47,480 Speaker 1: you you know, it'll that's all when you plug in 541 00:28:47,520 --> 00:28:50,040 Speaker 1: this device, when you sink sink it with whatever, whether 542 00:28:50,120 --> 00:28:52,680 Speaker 1: it's an app or it's your computer, uh, and you 543 00:28:52,720 --> 00:28:54,800 Speaker 1: get the data back saying you had a really good 544 00:28:54,880 --> 00:28:57,280 Speaker 1: night's sleep, and maybe because you took it off and 545 00:28:57,320 --> 00:29:01,640 Speaker 1: set it down next to you instead of or it. Um. 546 00:29:01,760 --> 00:29:03,719 Speaker 1: So yeah, I mean these are these are the basic 547 00:29:03,880 --> 00:29:07,320 Speaker 1: ways that gathers information. Now. The way it processes information 548 00:29:07,400 --> 00:29:10,520 Speaker 1: is different from one company to the next. It's all 549 00:29:10,960 --> 00:29:15,160 Speaker 1: various proprietary softwares and algorithms that take this, crunch the data, 550 00:29:15,240 --> 00:29:17,920 Speaker 1: and turn it into stuff that makes sense to us. Yeah, 551 00:29:18,000 --> 00:29:21,040 Speaker 1: some of them have really great onboard computers for doing that. Um, 552 00:29:21,200 --> 00:29:23,680 Speaker 1: it's very tiny onboard computers for doing that to to 553 00:29:23,720 --> 00:29:25,320 Speaker 1: give you a little bit of a live output, and 554 00:29:25,360 --> 00:29:27,680 Speaker 1: some of them give you zero live output other than 555 00:29:27,680 --> 00:29:29,960 Speaker 1: maybe a little blinking led or something like that. Right, 556 00:29:30,000 --> 00:29:32,440 Speaker 1: I had a body media fit, for example, and that 557 00:29:32,480 --> 00:29:35,920 Speaker 1: did not have its own screen. Rather, it would you 558 00:29:35,920 --> 00:29:38,920 Speaker 1: would have to sink that either to an app via Bluetooth, 559 00:29:39,440 --> 00:29:41,280 Speaker 1: or you would sink it to your computer via a 560 00:29:41,440 --> 00:29:44,520 Speaker 1: USB cable, and then you could make sense of what 561 00:29:45,120 --> 00:29:47,440 Speaker 1: information had been collecting. But you couldn't even tell what 562 00:29:47,840 --> 00:29:50,000 Speaker 1: it had been collecting until you did that. Right, There 563 00:29:50,040 --> 00:29:53,120 Speaker 1: was no uh screen indicators, so you couldn't read it 564 00:29:53,160 --> 00:29:54,880 Speaker 1: at a moment's notice unless you have to have your 565 00:29:54,880 --> 00:29:56,960 Speaker 1: phone they're paired with it, in which case you could 566 00:29:56,960 --> 00:29:59,720 Speaker 1: pull up the app and take a look that way. Um, 567 00:29:59,760 --> 00:30:02,320 Speaker 1: but yeah, there are other devices that have a dedicate screen, 568 00:30:02,360 --> 00:30:04,240 Speaker 1: so it's going to give you at least some information, 569 00:30:04,280 --> 00:30:07,680 Speaker 1: if not everything. And you know, it's again that depends 570 00:30:07,800 --> 00:30:10,360 Speaker 1: very highly on your personal preference and how much information 571 00:30:10,440 --> 00:30:12,440 Speaker 1: you need at the moment and how much you just 572 00:30:12,480 --> 00:30:14,200 Speaker 1: kind of want to check up on it later. Yeah, 573 00:30:14,200 --> 00:30:16,640 Speaker 1: And and some of these will give you information that's 574 00:30:16,720 --> 00:30:20,160 Speaker 1: in uh, very kind of concrete terms in the sense 575 00:30:20,160 --> 00:30:21,920 Speaker 1: of this is how far you walked, or this is 576 00:30:21,960 --> 00:30:26,000 Speaker 1: how how much activity your heart has had today. You know, 577 00:30:26,040 --> 00:30:29,520 Speaker 1: how how how often were you in that perfect zone 578 00:30:29,560 --> 00:30:32,920 Speaker 1: when you were working out versus you weren't quite pushing 579 00:30:32,960 --> 00:30:34,520 Speaker 1: yourself as hard as you needed to, or maybe you 580 00:30:34,560 --> 00:30:37,880 Speaker 1: were pushing yourself too hard you need to pull back off. 581 00:30:37,920 --> 00:30:43,440 Speaker 1: Some of them are a little more vague, like so 582 00:30:43,880 --> 00:30:47,880 Speaker 1: Nike's fuel Band, for example, everything's in fuel points and 583 00:30:47,880 --> 00:30:50,480 Speaker 1: and I know that the fuel band is very popular. 584 00:30:50,600 --> 00:30:55,600 Speaker 1: It's a gorgeous device, looks very full disclosure. My wife 585 00:30:55,840 --> 00:30:57,960 Speaker 1: has one. She loves it. She and she has the 586 00:30:58,000 --> 00:31:00,960 Speaker 1: app that it's paired up with her iPhone. So she 587 00:31:01,000 --> 00:31:04,720 Speaker 1: can see what's going on, but it's doing everything in 588 00:31:04,760 --> 00:31:07,560 Speaker 1: fuel points, and some people have said, some critics have 589 00:31:07,640 --> 00:31:12,040 Speaker 1: said that that makes it less useful because you don't 590 00:31:12,120 --> 00:31:15,760 Speaker 1: know what they mean necessarily. I think, well, you know, 591 00:31:16,200 --> 00:31:18,760 Speaker 1: it always reminds me of Microsoft Points and how you're 592 00:31:18,920 --> 00:31:21,760 Speaker 1: kind of sort of tricking the system in order to 593 00:31:21,880 --> 00:31:23,479 Speaker 1: make it a little bit more of a game and 594 00:31:23,600 --> 00:31:27,200 Speaker 1: less of a reality, which helps lots of people actually, 595 00:31:27,200 --> 00:31:28,680 Speaker 1: because because a lot of people don't want to know 596 00:31:28,680 --> 00:31:31,200 Speaker 1: how many steps they've taken. They're like, oh, that was 597 00:31:31,240 --> 00:31:34,480 Speaker 1: a lot of I wasted so much time getting fit yesterday. 598 00:31:34,480 --> 00:31:36,200 Speaker 1: Why did I do that? But if you get fuel points, 599 00:31:36,200 --> 00:31:39,440 Speaker 1: then you get especially especially if it has a gamification 600 00:31:39,520 --> 00:31:42,040 Speaker 1: element to it, where you are measuring your own activity 601 00:31:42,200 --> 00:31:45,440 Speaker 1: versus the activity of other people. If you set your 602 00:31:45,800 --> 00:31:47,760 Speaker 1: if you have a way of setting a specific goal 603 00:31:47,920 --> 00:31:49,920 Speaker 1: using one of these trackers, and the tracker can keep 604 00:31:50,400 --> 00:31:53,240 Speaker 1: track of that so that it will tell you, Hey, 605 00:31:53,320 --> 00:31:56,400 Speaker 1: you met your goal today. That's a reward system, right 606 00:31:56,440 --> 00:31:59,400 Speaker 1: you You immediately get that reward, that that sense of 607 00:31:59,440 --> 00:32:02,280 Speaker 1: satisfact and that you have met your goal for that day. 608 00:32:02,880 --> 00:32:06,160 Speaker 1: Then you have the added sasfaction. If there's a gamification 609 00:32:06,880 --> 00:32:10,760 Speaker 1: level there beyond just just getting the badge for yourself. 610 00:32:10,800 --> 00:32:12,960 Speaker 1: If you can share that badge with your friends and say, hey, guys, 611 00:32:13,040 --> 00:32:14,640 Speaker 1: check what I did. Did you do it? You didn't 612 00:32:14,680 --> 00:32:16,800 Speaker 1: do it? Stuck up right. Yeah. So if you're all 613 00:32:16,920 --> 00:32:19,640 Speaker 1: using like fitbits, for example, I know people who are 614 00:32:19,720 --> 00:32:22,600 Speaker 1: using fitbits as a way of challenging each other to 615 00:32:22,640 --> 00:32:25,400 Speaker 1: see how many steps they could take. Uh, and they would. 616 00:32:25,520 --> 00:32:28,400 Speaker 1: You know, there'd be groups of friends who were trying 617 00:32:28,480 --> 00:32:31,920 Speaker 1: to walk out walk each other, which is great. I mean, 618 00:32:32,080 --> 00:32:34,080 Speaker 1: you know, yeah, if that gives you the motivation to 619 00:32:34,120 --> 00:32:37,360 Speaker 1: get exercise, that's great. You know, there's there's nothing wrong 620 00:32:37,440 --> 00:32:40,680 Speaker 1: with using the desire to rub your friends faces and 621 00:32:40,720 --> 00:32:43,240 Speaker 1: your achievements in order for you to get fit, as 622 00:32:43,280 --> 00:32:47,600 Speaker 1: long as you, you know, practice some restraint a little 623 00:32:47,600 --> 00:32:49,520 Speaker 1: bit hytically, I can tell you that a punch to 624 00:32:49,560 --> 00:32:53,520 Speaker 1: the face is not good for your physical fitness. But yeah, so, 625 00:32:53,840 --> 00:32:55,680 Speaker 1: and there are other levels of a gamification to There's 626 00:32:55,680 --> 00:32:59,040 Speaker 1: some devices out there that have games built into the 627 00:32:59,160 --> 00:33:02,080 Speaker 1: software of the device or on the computer that you play, 628 00:33:02,120 --> 00:33:05,040 Speaker 1: so that as you use the device, as you move around, 629 00:33:05,120 --> 00:33:08,600 Speaker 1: you generate like online currency to play in a little 630 00:33:08,640 --> 00:33:12,080 Speaker 1: online game to Strive has that there's a little online 631 00:33:12,080 --> 00:33:14,800 Speaker 1: game where you can as you walk around, you generate coins, 632 00:33:15,240 --> 00:33:17,880 Speaker 1: and using those coins you can buy stuff in the 633 00:33:17,880 --> 00:33:21,480 Speaker 1: game world of a little bit like Sonics rings or 634 00:33:21,520 --> 00:33:25,959 Speaker 1: something like that. Yeah, like Conville, but using this you 635 00:33:26,000 --> 00:33:29,560 Speaker 1: generate the currency just by moving around, so that's the incentive. Yeah, 636 00:33:29,720 --> 00:33:32,120 Speaker 1: or um. An office favorite for a while was a 637 00:33:32,240 --> 00:33:34,080 Speaker 1: Zombie Run I think is the name of the app? 638 00:33:34,120 --> 00:33:37,920 Speaker 1: Which which which? I think it's run Zombie Run something 639 00:33:37,960 --> 00:33:40,200 Speaker 1: like that, something like that. Yes, that that gave you. 640 00:33:40,600 --> 00:33:42,960 Speaker 1: It was hooked up to a GPS related system on 641 00:33:43,000 --> 00:33:45,320 Speaker 1: your cell phone, and I would would give you these 642 00:33:45,360 --> 00:33:47,560 Speaker 1: little like are you out running the zombies or are 643 00:33:47,560 --> 00:33:49,720 Speaker 1: you totally dying? Right? Yeah? I I used to have. 644 00:33:49,840 --> 00:33:51,960 Speaker 1: In fact, I had the beta version of that app 645 00:33:52,240 --> 00:33:54,640 Speaker 1: back when it came out in the beta form for Android, 646 00:33:55,000 --> 00:33:56,720 Speaker 1: and the way I don't know if it still works 647 00:33:56,720 --> 00:33:58,720 Speaker 1: this way. I haven't used the app in a long time, 648 00:33:59,040 --> 00:34:01,120 Speaker 1: but the way it originally worked was that you would 649 00:34:01,120 --> 00:34:03,560 Speaker 1: be somewhere and you would tell it where you wanted 650 00:34:03,600 --> 00:34:05,680 Speaker 1: to go. You would open up a map program and 651 00:34:05,760 --> 00:34:08,239 Speaker 1: this zombie app and say, all right, here's you know 652 00:34:08,640 --> 00:34:11,000 Speaker 1: based on my GPS location, this is where I am, 653 00:34:11,360 --> 00:34:13,239 Speaker 1: this is where I want to go. It would then 654 00:34:13,360 --> 00:34:17,560 Speaker 1: generate these virtual zombies on the map that could actually move, 655 00:34:18,080 --> 00:34:20,960 Speaker 1: so the little blips would start moving toward you, and 656 00:34:21,000 --> 00:34:23,359 Speaker 1: your goal was to get to your destination without being 657 00:34:23,400 --> 00:34:25,719 Speaker 1: intercepted by one of those little zombie blips. So you 658 00:34:25,800 --> 00:34:28,520 Speaker 1: might have to find a different route than the one 659 00:34:28,560 --> 00:34:30,440 Speaker 1: you had intended, and you may have to book it, 660 00:34:30,560 --> 00:34:32,719 Speaker 1: and yeah, yeah, you might have to. You might have 661 00:34:32,760 --> 00:34:35,400 Speaker 1: to speed up and slow down, which in running terms 662 00:34:35,480 --> 00:34:38,000 Speaker 1: is is actually really great for training. So and there 663 00:34:38,040 --> 00:34:41,040 Speaker 1: were also, as I recall, there were story elements to 664 00:34:41,080 --> 00:34:43,520 Speaker 1: that game as well that that were added in later. 665 00:34:43,560 --> 00:34:45,320 Speaker 1: I had it where it was just the game mechanic, 666 00:34:45,360 --> 00:34:46,839 Speaker 1: but I know, and it may not even be that 667 00:34:46,880 --> 00:34:48,560 Speaker 1: app It maybe a similar one, because there were a 668 00:34:48,560 --> 00:34:50,359 Speaker 1: few that came out that had the same sort of theme. 669 00:34:50,800 --> 00:34:53,839 Speaker 1: But there was one where there was an overall progressive 670 00:34:53,880 --> 00:34:57,840 Speaker 1: storyline and as you participated, you would unlock more of 671 00:34:57,840 --> 00:35:01,840 Speaker 1: the story. I got eaten. I couldn't get from I 672 00:35:01,880 --> 00:35:05,040 Speaker 1: couldn't get from the train station to my house because 673 00:35:05,040 --> 00:35:07,160 Speaker 1: there was really there was only one way you could 674 00:35:07,160 --> 00:35:09,359 Speaker 1: go by foot, and it kept wanting me to cut 675 00:35:09,360 --> 00:35:12,560 Speaker 1: through the woods. I kept wanting to not run into 676 00:35:12,640 --> 00:35:15,680 Speaker 1: barbed wire fences that are hard to see. Look, if 677 00:35:15,680 --> 00:35:17,920 Speaker 1: you don't bring your bolt cutters to the zombie apocalypse, 678 00:35:17,920 --> 00:35:19,520 Speaker 1: then I don't think you're going to get very far. 679 00:35:19,600 --> 00:35:22,240 Speaker 1: And I'm no longer allowed to bring my bolt cutters 680 00:35:22,239 --> 00:35:24,480 Speaker 1: to work. That was the problem, right, because this was 681 00:35:24,520 --> 00:35:27,960 Speaker 1: my commute back home, and so I already had that 682 00:35:28,080 --> 00:35:30,600 Speaker 1: limitation set on me. I tell you, you make one 683 00:35:30,719 --> 00:35:35,120 Speaker 1: silly mistake with a with an internet line and they 684 00:35:35,160 --> 00:35:37,440 Speaker 1: just never let you forget it. It's crazy. We're very 685 00:35:37,520 --> 00:35:40,200 Speaker 1: unforgiving here and how stuff works. But the game of 686 00:35:40,280 --> 00:35:43,360 Speaker 1: vacation obviously plays a big part. Yeah, and you know 687 00:35:43,440 --> 00:35:47,080 Speaker 1: it's it's the recommended target number of steps per day 688 00:35:47,080 --> 00:35:50,440 Speaker 1: for for healthy human people is about ten thousand and 689 00:35:50,640 --> 00:35:52,799 Speaker 1: um and that's that equals out to maybe about five 690 00:35:52,800 --> 00:35:56,000 Speaker 1: miles and uh and and yeah, so anything that helps 691 00:35:56,040 --> 00:35:59,240 Speaker 1: people get to that. And and in fact, Dina Bravada, 692 00:35:59,280 --> 00:36:01,400 Speaker 1: the person I mentioned at the top of the podcast, 693 00:36:01,440 --> 00:36:04,280 Speaker 1: who you know, she's she's a specialist in in health 694 00:36:04,320 --> 00:36:07,960 Speaker 1: matters and has expressed some skeptic skepticism as to whether 695 00:36:08,040 --> 00:36:11,640 Speaker 1: or not these activity trackers are really you know, a 696 00:36:11,760 --> 00:36:14,080 Speaker 1: huge benefit. I mean, they helped the people who are 697 00:36:14,080 --> 00:36:16,880 Speaker 1: already interested. But she did notice she did a study 698 00:36:16,960 --> 00:36:19,399 Speaker 1: or she was part of the study where uh they 699 00:36:19,440 --> 00:36:23,719 Speaker 1: gave pedometers to a group of participants, UH in a 700 00:36:23,920 --> 00:36:27,280 Speaker 1: randomized trial where some some participants didn't get a podometer, 701 00:36:27,440 --> 00:36:30,000 Speaker 1: some did, and they were all asked to uh kind 702 00:36:30,040 --> 00:36:31,960 Speaker 1: of track their activities. And it turned out that the 703 00:36:32,000 --> 00:36:35,480 Speaker 1: people who had the pedometers increased their physical activity by 704 00:36:35,520 --> 00:36:39,920 Speaker 1: about two thousand three steps per day over the baseline. 705 00:36:40,480 --> 00:36:42,960 Speaker 1: And uh and so that ended up being a twenty 706 00:36:43,040 --> 00:36:47,600 Speaker 1: seven percent increase in physical activity. And that's provided said, well, 707 00:36:47,719 --> 00:36:51,560 Speaker 1: that's significant. So if you have, if you're actually using 708 00:36:51,600 --> 00:36:54,160 Speaker 1: one of these things and you're paying attention to it, 709 00:36:54,239 --> 00:36:57,440 Speaker 1: then you are more likely to actually engage in more 710 00:36:57,480 --> 00:37:01,200 Speaker 1: physical activity and thus exercise more and be have a 711 00:37:01,200 --> 00:37:04,799 Speaker 1: healthier lifestyle. Um. And that's that's the chief argument for 712 00:37:04,840 --> 00:37:07,560 Speaker 1: these activity trackers is the idea that with this information 713 00:37:08,040 --> 00:37:12,680 Speaker 1: you can really be more mindful of what you are 714 00:37:12,719 --> 00:37:15,040 Speaker 1: doing and how it's affecting you. A lot of these 715 00:37:15,080 --> 00:37:19,319 Speaker 1: activity trackers come with software that also have as part 716 00:37:19,320 --> 00:37:22,840 Speaker 1: of it a way of keeping a a food journal, 717 00:37:23,560 --> 00:37:26,239 Speaker 1: which is also very important because you could be exercising, 718 00:37:26,239 --> 00:37:28,680 Speaker 1: but if you're not eating well, then that's not gonna 719 00:37:28,680 --> 00:37:32,160 Speaker 1: help you. You can be sabotaging yourself certainly. So for example, 720 00:37:32,200 --> 00:37:35,480 Speaker 1: the body media fit device I had, uh part of 721 00:37:35,520 --> 00:37:37,320 Speaker 1: the software that you would have once you had to 722 00:37:37,360 --> 00:37:39,520 Speaker 1: subscribe to it. So you you'd have to buy the 723 00:37:39,560 --> 00:37:41,600 Speaker 1: device and you had to subscribe to the service. But 724 00:37:41,640 --> 00:37:44,680 Speaker 1: once you subscribe to the service, you could track your meals. 725 00:37:44,800 --> 00:37:46,279 Speaker 1: And every meal you would track, it would tell you 726 00:37:46,320 --> 00:37:49,160 Speaker 1: how many calories you've consumed. It would break it down 727 00:37:49,200 --> 00:37:53,560 Speaker 1: by what type of calories they were, etcetera. And then 728 00:37:53,760 --> 00:37:56,000 Speaker 1: the the information from the device would tell you how 729 00:37:56,000 --> 00:37:58,359 Speaker 1: many calories you would burned. And so that would give 730 00:37:58,360 --> 00:38:01,000 Speaker 1: you an idea like did I burn more reason I consumed? 731 00:38:01,040 --> 00:38:03,520 Speaker 1: If I did, then I'm on the road to losing weight. 732 00:38:03,680 --> 00:38:06,319 Speaker 1: I mean that's a that's a very basic way of 733 00:38:06,440 --> 00:38:09,600 Speaker 1: figuring it out, calories out. But uh, it also meant 734 00:38:09,640 --> 00:38:12,239 Speaker 1: that you were much more mindful when you started doing 735 00:38:12,280 --> 00:38:14,239 Speaker 1: things like you sat down for a meal. You'd think, oh, 736 00:38:14,280 --> 00:38:15,719 Speaker 1: wait a minute, you know, if I want to if 737 00:38:15,760 --> 00:38:17,879 Speaker 1: I want to be on track and I don't want 738 00:38:17,880 --> 00:38:21,319 Speaker 1: to have to go home and run five miles. I 739 00:38:21,320 --> 00:38:24,839 Speaker 1: probably shouldn't pig out on that deep fried onion, even 740 00:38:24,920 --> 00:38:28,600 Speaker 1: though it's super tasty. Now, there is a flip side 741 00:38:28,600 --> 00:38:30,880 Speaker 1: to this coin, of course, we're talking all about keeping 742 00:38:30,880 --> 00:38:34,880 Speaker 1: all this data and really looking at and making something meaningful. Uh, 743 00:38:35,120 --> 00:38:37,400 Speaker 1: there can come a point where too much data is 744 00:38:37,440 --> 00:38:40,160 Speaker 1: actually harmful, where you're just you're just overwhelmed by all 745 00:38:40,200 --> 00:38:43,040 Speaker 1: the information and you can't really see a way of 746 00:38:43,160 --> 00:38:45,040 Speaker 1: using it in a in a way that makes sense. 747 00:38:45,520 --> 00:38:47,600 Speaker 1: That can happen. I don't know that most I think 748 00:38:47,640 --> 00:38:50,920 Speaker 1: most activity trackers are pretty good where you're not going 749 00:38:50,960 --> 00:38:53,840 Speaker 1: to get that much unless you're really digging down and 750 00:38:53,880 --> 00:38:55,120 Speaker 1: you want to see. Oh, no, I want to I 751 00:38:55,160 --> 00:38:57,160 Speaker 1: want this in pie chart form. No, I wanted in 752 00:38:57,239 --> 00:39:00,359 Speaker 1: line graph form. But that is one of those things 753 00:39:00,360 --> 00:39:02,120 Speaker 1: that we're going to be looking into later in a 754 00:39:02,200 --> 00:39:04,280 Speaker 1: in a later episode of tech Stuff. We've already planned 755 00:39:04,600 --> 00:39:06,800 Speaker 1: on recording this. We haven't recorded it yet, but we 756 00:39:06,840 --> 00:39:09,239 Speaker 1: want to do an episode where we're talking about kind 757 00:39:09,239 --> 00:39:12,359 Speaker 1: of that anxiety you get when you have so much 758 00:39:12,400 --> 00:39:15,160 Speaker 1: information that you know, you start to think, is my 759 00:39:15,280 --> 00:39:18,879 Speaker 1: life being boiled down to data points and charts? Yeah, 760 00:39:18,920 --> 00:39:20,480 Speaker 1: and how much of that is healthy, and you know, 761 00:39:20,560 --> 00:39:23,279 Speaker 1: it's it's yeah, whether whether or not it's okay that 762 00:39:23,320 --> 00:39:26,720 Speaker 1: we know so much about ourselves at any given second. Yeah, 763 00:39:26,960 --> 00:39:29,480 Speaker 1: I've I know more about me than I'm comfortable with. 764 00:39:30,000 --> 00:39:32,239 Speaker 1: But uh, and that's for a later episode. And I 765 00:39:32,320 --> 00:39:34,680 Speaker 1: really do think that most of these physical activity trackers 766 00:39:34,719 --> 00:39:38,000 Speaker 1: aren't quite at that level. It is a little interesting 767 00:39:38,080 --> 00:39:40,279 Speaker 1: to you know, sit there and say, oh, look at 768 00:39:40,320 --> 00:39:43,399 Speaker 1: my sleep patterns. What can I do to make these better? Uh, 769 00:39:43,440 --> 00:39:45,840 Speaker 1: there's really only so much you can do. And you know, 770 00:39:45,920 --> 00:39:48,239 Speaker 1: you can try and make sure that the environment you're 771 00:39:48,239 --> 00:39:52,239 Speaker 1: in is conducive to sleep and rest, but there are 772 00:39:52,239 --> 00:39:53,960 Speaker 1: a lot of little things that you can that you 773 00:39:54,000 --> 00:39:55,839 Speaker 1: can work on that that a lot of people might 774 00:39:55,920 --> 00:39:59,360 Speaker 1: not be completely aware of. Um. And and again a 775 00:39:59,400 --> 00:40:03,680 Speaker 1: lot of this is just about awareness. And along those lines, um, 776 00:40:03,719 --> 00:40:05,560 Speaker 1: you know, these these fitness trackers that we were talking 777 00:40:05,560 --> 00:40:08,880 Speaker 1: about can run from fifty fifty dollars on the low end, 778 00:40:08,880 --> 00:40:12,160 Speaker 1: I guess, you know, ten dollars for up to two 779 00:40:12,880 --> 00:40:15,200 Speaker 1: for some of the super fancy ones, or or even 780 00:40:15,200 --> 00:40:18,320 Speaker 1: more for the really high level performance triathlon kind of things. 781 00:40:18,360 --> 00:40:21,000 Speaker 1: So there's a huge I mean or down to free 782 00:40:21,000 --> 00:40:23,680 Speaker 1: apps that you can download for your smartphone right, which 783 00:40:23,719 --> 00:40:26,279 Speaker 1: is mostly using GPS tracking to figure out how far 784 00:40:26,400 --> 00:40:30,200 Speaker 1: you've gone exactly, keeping in mind that that's not necessarily 785 00:40:30,239 --> 00:40:32,960 Speaker 1: going to translate into a very accurate measure of how 786 00:40:33,040 --> 00:40:35,359 Speaker 1: much how many calories you burn, but you at least 787 00:40:35,400 --> 00:40:37,640 Speaker 1: give you an idea of how far you went. Uh, 788 00:40:37,960 --> 00:40:41,680 Speaker 1: you know, it's It's definitely something that I've been interested 789 00:40:41,719 --> 00:40:43,520 Speaker 1: in the past. And you know, we're about to do 790 00:40:43,600 --> 00:40:46,520 Speaker 1: this exercise thing here at work where we all have pedometers, 791 00:40:46,560 --> 00:40:48,839 Speaker 1: so I'm sure we're gonna I'm in a group with 792 00:40:49,520 --> 00:40:51,960 Speaker 1: Holly Fry, who is a marathon runner, so I know 793 00:40:52,160 --> 00:40:55,160 Speaker 1: my group is going to do really well. Yeah, so 794 00:40:55,200 --> 00:41:00,600 Speaker 1: I don't plan on moving for most of July. Uh, 795 00:41:00,640 --> 00:41:04,320 Speaker 1: that's the spirit. But but you know, it really depends 796 00:41:04,320 --> 00:41:06,759 Speaker 1: on what you want the device for, how you're going 797 00:41:06,800 --> 00:41:09,960 Speaker 1: to use it, and also, like we said, read reviews, 798 00:41:10,000 --> 00:41:12,160 Speaker 1: because some of the ones that are really expensive may 799 00:41:12,200 --> 00:41:14,520 Speaker 1: not have all the features you want and may not 800 00:41:15,160 --> 00:41:18,560 Speaker 1: perform better than than less right, and they might just 801 00:41:18,600 --> 00:41:20,880 Speaker 1: be you know, for a different subset of human person 802 00:41:20,920 --> 00:41:23,279 Speaker 1: than than you happen to be and not yea, not 803 00:41:23,320 --> 00:41:24,880 Speaker 1: all of these are for everybody. If I may make 804 00:41:24,920 --> 00:41:28,880 Speaker 1: a personal recommendation. D C. Rainmaker has a blog that 805 00:41:29,040 --> 00:41:32,239 Speaker 1: is brilliant. He's a triathlon runner, but um our triathlon 806 00:41:32,560 --> 00:41:38,040 Speaker 1: athlete who who's just triathlete, Yes, that would be that 807 00:41:38,080 --> 00:41:40,719 Speaker 1: would be the technical term for that. Who has just 808 00:41:40,760 --> 00:41:44,560 Speaker 1: reviewed all of the devices, all of them, all of them, 809 00:41:44,560 --> 00:41:49,520 Speaker 1: and and and he gets very highly technical, which I love, 810 00:41:50,000 --> 00:41:52,920 Speaker 1: um and but but also tends to put his his 811 00:41:53,000 --> 00:41:56,840 Speaker 1: kind of final thoughts in an extremely succinct package. Excellent, excellent, 812 00:41:56,880 --> 00:42:01,760 Speaker 1: good recommendation. Yeah, uh, and you know again, take a look, 813 00:42:02,640 --> 00:42:05,560 Speaker 1: find out what's going to work right, work well for you. 814 00:42:05,560 --> 00:42:06,960 Speaker 1: You know, if if you have one that's going to 815 00:42:07,000 --> 00:42:09,200 Speaker 1: sync up with a smartphone, make sure that it's compatible 816 00:42:09,200 --> 00:42:11,200 Speaker 1: with which you with your smartphone. Make sure that your 817 00:42:11,239 --> 00:42:14,240 Speaker 1: smartphone has the type of Bluetooth that the device wants 818 00:42:14,280 --> 00:42:16,840 Speaker 1: to sync up with, because that can be very very messy. Right. 819 00:42:16,880 --> 00:42:18,200 Speaker 1: You can say, well, it was supposed to work with 820 00:42:18,239 --> 00:42:22,200 Speaker 1: an iOS device, and technically this iPhone three G is 821 00:42:22,239 --> 00:42:25,919 Speaker 1: an iOS device, but you know, yeah, that's obviously something 822 00:42:25,960 --> 00:42:29,360 Speaker 1: you want to make sure is all all working before 823 00:42:29,400 --> 00:42:33,480 Speaker 1: you you dive in. But uh, yeah, I think these 824 00:42:33,520 --> 00:42:37,000 Speaker 1: are really interesting devices. I've seen some great implementations. I've 825 00:42:37,000 --> 00:42:40,040 Speaker 1: seen some gorgeous designs. The body media fit thing I 826 00:42:40,080 --> 00:42:43,040 Speaker 1: had worked really well for me. Um, I haven't been 827 00:42:43,120 --> 00:42:45,960 Speaker 1: using it for a while, but uh it's you know, 828 00:42:46,040 --> 00:42:49,239 Speaker 1: it was definitely an interesting thing that that you wear 829 00:42:49,239 --> 00:42:51,279 Speaker 1: it all the time except when you're going to get wet, 830 00:42:51,840 --> 00:42:54,160 Speaker 1: and uh so that was kind of interesting the idea 831 00:42:54,840 --> 00:42:58,160 Speaker 1: that this became a part of me for for several months. 832 00:42:58,200 --> 00:42:59,840 Speaker 1: And I did lose weight because I was very my 833 00:43:00,080 --> 00:43:03,960 Speaker 1: full about my activity and what I was eating, and um, 834 00:43:04,000 --> 00:43:06,160 Speaker 1: you know, I should really get back into it. But uh, 835 00:43:06,600 --> 00:43:08,399 Speaker 1: not that I've gained a lot of weight.
