WEBVTT - How close are we to holographic environments? 0:00:01.120 --> 0:00:04.280 Welcome to you stuff you should know from house Stuff 0:00:04.280 --> 0:00:12.879 Works dot com. Hey, and welcome to the podcast. I'm 0:00:12.960 --> 0:00:17.680 Josh Clark. There's Charles W. Chuck Bryant that makes this stuff. 0:00:17.680 --> 0:00:21.120 You snow. Jerry's back there. We're all set got our 0:00:21.160 --> 0:00:24.560 Mike's got the dinosaur. What's this dinosaur's name? Frank the chairs? 0:00:25.000 --> 0:00:28.160 Uncle is here year old uncle who's in the Olympics, 0:00:28.280 --> 0:00:32.720 Uncle Merle, the Frank the chair. His uncle Merle is 0:00:32.720 --> 0:00:35.839 the dinosaur. Oh I was talking about the chairs sitting in? 0:00:35.960 --> 0:00:38.120 Is that a nameless Oh yeah, this isn't Frank. Is 0:00:38.159 --> 0:00:42.600 it Frank's on set at our TV show that we're shooting, 0:00:42.680 --> 0:00:47.640 unfortunately with a TV show we're making. Is that set in? Uh? Yeah, 0:00:47.640 --> 0:00:49.000 it's set in that I had to sit in that 0:00:49.040 --> 0:00:51.640 stupid chair for sixty hours a couple of weeks ago. Yeah, 0:00:51.640 --> 0:00:55.520 it's hilarious. Yeah, they followed us there. Uh okay, So 0:00:55.560 --> 0:00:59.800 this is Uncle Merle the dinosaur, the stegasaurs. I believe sure. 0:01:00.040 --> 0:01:02.160 It's like a stack of source cross with a sharp 0:01:02.160 --> 0:01:07.520 pay Look at all those wrinkles. That's about it, all right. 0:01:07.840 --> 0:01:10.679 If you want to get in touch with us, hey, buddy, 0:01:10.720 --> 0:01:12.920 if you don't mind if I plug my November page 0:01:12.959 --> 0:01:16.000 real quick, please do. I am growing a mustache this 0:01:16.080 --> 0:01:22.959 month for November for uh for cancer research, specifically male 0:01:23.000 --> 0:01:27.080 prostate cancer research. That's right. And you can donate to 0:01:27.120 --> 0:01:29.560 my team, which would be pretty cool because you know, 0:01:29.760 --> 0:01:32.160 you get a free podcast and it'd be nice to 0:01:32.440 --> 0:01:36.680 throw a little money towards cancer research. Being nice here, 0:01:36.840 --> 0:01:39.360 give him some money. He's growing out facial here to 0:01:39.440 --> 0:01:45.280 help a charitable organization engage in really important scientific research. 0:01:45.440 --> 0:01:47.720 That's right. And you can go to mobro dot c 0:01:47.920 --> 0:01:51.440 O slash Charles Bryant and that's my page, or just 0:01:51.480 --> 0:01:53.880 go to the November site. Type in Charles Bryan in 0:01:53.920 --> 0:01:56.720 the search bar and look for the picture of me. 0:01:56.760 --> 0:01:58.600 There's only a couple of us out there. Chuck's wearing 0:01:58.600 --> 0:02:02.680 a red shirt. It's yeah, um, so what is that again? 0:02:02.720 --> 0:02:06.040 That's mo bro dot CEO slash Charles Bryant. Yes, thank 0:02:06.080 --> 0:02:08.720 you in advance. Yeah, that's nice, Chuck. All right, let's 0:02:08.720 --> 0:02:12.520 get to it. Chuck, you selected this one. How do 0:02:12.600 --> 0:02:16.079 you feel it sounded a lot cooler? Yeah. We're talking 0:02:16.080 --> 0:02:18.880 about holographic environments. Yeah, and you hear that you think 0:02:19.000 --> 0:02:22.400 Man Star Trek. Yeah, it comes to life. So I 0:02:22.880 --> 0:02:24.600 wanted to make sure I knew what I was talking about, 0:02:24.639 --> 0:02:27.560 and I went and looked up the holidack. Yeah, and 0:02:27.600 --> 0:02:30.560 it's apparently just from the next generation, like it wasn't 0:02:30.560 --> 0:02:33.400 like original. I didn't see anything. I even looked on 0:02:33.440 --> 0:02:36.639 a Star Trek wiki and it's it seemed to indicate 0:02:37.120 --> 0:02:39.680 the first I'm so nervous right now. Well let's say this. 0:02:39.720 --> 0:02:41.680 We'll find out one way or the other very quickly. 0:02:41.840 --> 0:02:45.840 But it seemed to indicate from my cursory research that 0:02:46.040 --> 0:02:51.600 the holidack was a feature on the Enterprise from the 0:02:51.639 --> 0:02:57.720 twenty three sixties e g. Or I e. The next generation. 0:02:57.840 --> 0:03:01.000 All right, so what it was? The hollow deck? Have 0:03:01.080 --> 0:03:04.040 you seen it? Are you familiar? Star Trek cital? And 0:03:04.040 --> 0:03:05.360 now I was in a Star Trek guy. I mean, 0:03:06.200 --> 0:03:07.720 it just kind of got past me. But have you 0:03:07.760 --> 0:03:09.919 seen it? Did you? Did you see it? Yeah? Okay, 0:03:09.960 --> 0:03:12.600 it's cool. You know, it is a projection, a holographic 0:03:12.800 --> 0:03:16.919 projection room, and basically, you know, is what you would think. 0:03:16.960 --> 0:03:19.320 You know, remember in Star Wars, which I am a 0:03:19.320 --> 0:03:22.560 fan of, when our two D two spit out the 0:03:22.840 --> 0:03:27.400 little holographic image of Princess Leiah rendering her message. Um, 0:03:27.600 --> 0:03:30.280 imagine a room of life sized people doing that as 0:03:30.320 --> 0:03:34.519 if you're interacting. Yes, that's a very important key, um, 0:03:34.600 --> 0:03:36.840 because what we're talking about is not just a three 0:03:36.920 --> 0:03:41.320 D projection like Star Wars clunked along with. But we're 0:03:41.320 --> 0:03:44.920 talking about the Star Trek holographic environment where you can 0:03:44.960 --> 0:03:47.000 move around and you get a three D and sixty 0:03:47.040 --> 0:03:51.200 degree view and you can shake hands and maybe uh, 0:03:51.480 --> 0:03:55.000 have a cocktail or play a trombone or something with 0:03:55.600 --> 0:03:59.560 someone else in a virtual environment. But you can interact 0:03:59.640 --> 0:04:02.880 like you don't like when you walk around the backside 0:04:02.880 --> 0:04:05.640 of somebody. It's not you're not getting in the way 0:04:05.680 --> 0:04:08.920 of the projector. Can I read a line from the article? Yes, 0:04:09.120 --> 0:04:11.680 eventually you will even be able to hug other people 0:04:11.800 --> 0:04:15.640 using this technology. They should have put hug in quotes 0:04:16.160 --> 0:04:19.159 because because it's not a hug, No, they're not really there. 0:04:21.160 --> 0:04:24.560 Oh I meant I thought that they were talking about 0:04:24.600 --> 0:04:28.240 like having virtual sex. Of course, it's going to go 0:04:28.279 --> 0:04:30.080 to virtual sex. It's gonna be the first thing that 0:04:30.120 --> 0:04:33.200 they come up with. That's what everybody at Microsoft is 0:04:33.240 --> 0:04:35.320 working on right now. I'm quite sure you'll make a 0:04:35.360 --> 0:04:40.799 trillion dollars it's like, uh, is it total recall? Ah, yeah, 0:04:40.880 --> 0:04:46.279 where you had the three D or virtual reality experiences. Yeah, 0:04:46.360 --> 0:04:48.320 and I'm sure it's been another stuff too. I'm not 0:04:48.360 --> 0:04:51.520 thinking of like total recall the remake. Yeah, that was 0:04:51.560 --> 0:04:53.359 the other thing I was thinking of. All right, what 0:04:53.360 --> 0:04:56.920 we're talking about telet immersion. That's the real name for it, yes, 0:04:57.000 --> 0:05:00.360 not the holidack, And it right now is mainly being 0:05:00.640 --> 0:05:07.360 um developed for a few different things, potentially video game use, hugging, 0:05:07.560 --> 0:05:13.040 hugging your family members at Christmas, yeah you can't be there, um, 0:05:13.080 --> 0:05:16.120 but mainly for uh, something that's not quite as exciting 0:05:16.400 --> 0:05:20.839 video conferencing, right which we've seen like the pinnacle of 0:05:20.960 --> 0:05:25.480 video conferencing right now, I think so, Yeah, man, they 0:05:25.480 --> 0:05:28.120 owe us a couple of bucks. Yeah, we've plugged them 0:05:28.120 --> 0:05:31.560 like heavily. Well, I mean it's amazing technology, it is, 0:05:31.680 --> 0:05:37.840 but it's it's just like nothing compared to teleimersion. Yeah, 0:05:37.960 --> 0:05:40.880 goal of true. And this article is has got to 0:05:40.880 --> 0:05:44.960 be outdated, because laughably out of date because after witnessing 0:05:44.960 --> 0:05:47.760 the Tanburg in use, which basically feels like you're sitting 0:05:47.800 --> 0:05:50.120 in a room, you know, it's HD It's not like 0:05:50.120 --> 0:05:52.520 a hologram or three D or anything. But it's really 0:05:52.520 --> 0:05:53.960 good and it feels like you're sitting in a room 0:05:53.960 --> 0:05:56.920 with someone. There's no lag, there's no stuttering. And this 0:05:57.040 --> 0:05:59.599 article talks about like these days, you know, there's some 0:05:59.600 --> 0:06:03.600 stuttering and flickering when you try to teleconference. Right, they 0:06:03.640 --> 0:06:06.440 figured that all out, they did. Um. They also this 0:06:06.560 --> 0:06:09.920 article you know, this article also no it's not but 0:06:10.000 --> 0:06:12.200 which I mean, like it's kind of I think where 0:06:12.240 --> 0:06:16.320 the tele immersion was at when this article was written. 0:06:16.640 --> 0:06:19.000 Where we're at with like it's pretty decent now, you know. 0:06:19.600 --> 0:06:22.679 But the the the author Kevin Bondser makes a point 0:06:22.720 --> 0:06:25.600 like if you walk out of the way of the webcam, 0:06:25.960 --> 0:06:28.960 nobody can see you any longer if you are um, 0:06:29.520 --> 0:06:33.160 like when you're looking at the computer screen, the webcams 0:06:33.160 --> 0:06:35.320 getting your eyes, but you're not making eye contact, like 0:06:35.360 --> 0:06:38.359 nobody thinks to do that. That's all this stuff just 0:06:38.440 --> 0:06:41.760 kind of goes away with tele immersion. Um, because you 0:06:41.880 --> 0:06:44.920 have a webcam that's tracking your eyes to see where 0:06:44.920 --> 0:06:47.080 you're where you're looking at. That's a big part of it. 0:06:47.920 --> 0:06:52.120 Facial recognition helps with that too, and then also there's 0:06:52.160 --> 0:06:54.719 a camera ray. It's not just one webcam pointing at you. 0:06:54.839 --> 0:06:57.840 Your there's cameras around you, but pretty much three D 0:06:57.960 --> 0:07:02.400 and sixty degrees, so there capturing everything you're doing. So 0:07:02.520 --> 0:07:07.640 you can't leave the the view of the other person. Yeah, 0:07:07.680 --> 0:07:10.120 you have to go into a different room and then 0:07:10.800 --> 0:07:13.680 what you know, what's the point? Hang up? Your call 0:07:13.800 --> 0:07:16.040 is over at that point, unless you just have to 0:07:16.200 --> 0:07:19.080 be real quick and you're like, hold on, I'll be 0:07:19.200 --> 0:07:22.480 right back. Um. One thing that's in the way right now. 0:07:22.520 --> 0:07:24.080 I mean, they made a lot of headway that this 0:07:24.200 --> 0:07:28.120 article points out in two thousand, twelve years ago is 0:07:28.120 --> 0:07:32.360 when they made their first big breakthrough. Um uh, the 0:07:32.480 --> 0:07:37.600 National telet Immersion Initiative. Yes, working together Chapel Hill looks 0:07:37.600 --> 0:07:40.920 like North Carolina. Did you look up this group? Are 0:07:40.920 --> 0:07:44.840 they still around? Their websites still around? But they reached 0:07:44.840 --> 0:07:48.840 their pinnacle in May two thousand. Is it my space? Oh? Man, 0:07:48.960 --> 0:07:55.760 yeah it is. And it's like what we're doing two thousand? Nothing? Nothing? 0:07:56.560 --> 0:07:58.200 All right? Well, at the time, it was a big 0:07:58.200 --> 0:08:00.480 breakthrough because it was the first time they were able 0:08:00.520 --> 0:08:06.360 to see three dimensional holographic images of like colleagues in 0:08:06.360 --> 0:08:09.360 different cities. Yeah, all sitting in the same room, right, 0:08:09.360 --> 0:08:11.160 And it was a big deal. Yeah, and that's we 0:08:11.160 --> 0:08:13.640 should also say, like the point of telemersion is basically 0:08:13.720 --> 0:08:16.960 to create say if you want to telecommunity and you 0:08:17.000 --> 0:08:21.360 have a conference, rather than everybody flying to the conference room, 0:08:21.640 --> 0:08:24.800 you have a virtual conference room set up to where 0:08:24.840 --> 0:08:28.920 everybody basically projects himself into this shared space, the shared 0:08:29.000 --> 0:08:31.120 room that you can get up and move around and 0:08:31.400 --> 0:08:36.480 see from different angles and um, each user is depicted 0:08:36.800 --> 0:08:39.160 three D and sixty degrees. So it it is a 0:08:39.240 --> 0:08:41.520 sort of telepresence, is what they call it. Yeah, and 0:08:41.559 --> 0:08:43.280 it's sort of a green initiative to you could look 0:08:43.280 --> 0:08:45.640 at it that way. Yeah, save a lot on jet 0:08:45.679 --> 0:08:50.239 fuel and commuting costs, and that there's some huge challenges 0:08:50.280 --> 0:08:53.119 to this there we're back in two thousand and it's um, 0:08:53.160 --> 0:08:55.520 a lot of them are still around. One of them 0:08:55.679 --> 0:08:59.840 is the kind of bandwidth that we will need because 0:08:59.880 --> 0:09:02.960 I think it's said for the frame to refresh itself 0:09:03.080 --> 0:09:05.920 um at ten, or the screen to refresh itself, or 0:09:05.920 --> 0:09:09.240 the projection to refresh it time frames a second, that'd 0:09:09.240 --> 0:09:12.560 be seamless, but it was hitting at like three back 0:09:12.600 --> 0:09:14.640 in two thousand. I wonder what is that now. I'm 0:09:14.640 --> 0:09:18.240 sure that we can do that now, but the problem is, um, 0:09:18.280 --> 0:09:23.240 transmitting that data right is problematic, shuts up a lot 0:09:23.240 --> 0:09:26.160 of bandwidth. Yeah. So you're talking about two things. A 0:09:27.800 --> 0:09:31.280 computers that are way more juiced than they are now 0:09:31.360 --> 0:09:34.880 even now, and you're talking about an internet um from 0:09:34.880 --> 0:09:39.120 my internet to basically yeah, now that's still going on, right, 0:09:39.440 --> 0:09:44.480 it's um basically this initiative by a bunch of universities 0:09:44.520 --> 0:09:49.600 around the country to wire the US at speeds that 0:09:49.640 --> 0:09:53.640 are just blistering fast compared to what we've got now, 0:09:54.080 --> 0:09:57.679 up to a thousand times faster. That's really really fast. Um. 0:09:57.840 --> 0:10:02.280 They also have enormous storage capabilities, and I saw one 0:10:02.320 --> 0:10:04.560 of the things that they're doing is using this to 0:10:04.640 --> 0:10:08.520 move out to underserved areas of the country. Oh really, Yeah, 0:10:08.520 --> 0:10:10.400 it's not just like just it's not just for New 0:10:10.480 --> 0:10:14.680 York or Francisco. It's like, yeah, it's for North Dakota. 0:10:15.160 --> 0:10:22.280 Why can't North Dakota get online? Finally, that's funny. Uh 0:10:22.320 --> 0:10:29.120 but true. You also have UM, well just basically tracking somebody, 0:10:29.160 --> 0:10:32.880 which Microsoft has done a lot to get past. Are 0:10:32.920 --> 0:10:36.800 you talking about that new thing, the hollow desk? Yes, yeah, 0:10:36.800 --> 0:10:39.040 I just found this today. Did you look at that 0:10:39.160 --> 0:10:43.240 the video? Yeah, it's pretty cool. Microsoft is developing something 0:10:43.559 --> 0:10:47.199 and this is current UM called the hollow desk, and 0:10:47.600 --> 0:10:50.800 UM he uses an overhead screen to project a two 0:10:50.840 --> 0:10:54.720 D two D image through a half silvered beam splitter 0:10:55.000 --> 0:10:58.800 onto a desktop. Basically, what it looks like is, UM, 0:10:58.880 --> 0:11:01.239 it looks like you're working on a desk with a 0:11:01.400 --> 0:11:03.719 screen between you and the desk. I can see through 0:11:03.800 --> 0:11:06.480 clear screen. Yeah, so if you look below that screen, 0:11:06.520 --> 0:11:08.920 you're just gonna see your hands doing nothing. If you 0:11:08.960 --> 0:11:12.400 look through that screen, you're gonna see holographic images. In 0:11:12.400 --> 0:11:15.120 this case, there were like little glowing balls that you 0:11:15.120 --> 0:11:17.959 could pick up and juggle, and you could pick it 0:11:18.040 --> 0:11:19.880 up with a piece of paper. You could put it 0:11:19.920 --> 0:11:22.920 in a coffee cup and swirl it around. Pretty cool. Yeah, 0:11:22.960 --> 0:11:27.840 that's huge. That's hugely different than anything that this article 0:11:27.960 --> 0:11:30.200 was talking about or anything we thought of before, because 0:11:30.679 --> 0:11:34.600 like you're interacting with a virtual environment. It's reacting to you. 0:11:34.880 --> 0:11:37.960 I mean, yeah, super advanced. And it was like you 0:11:38.000 --> 0:11:40.840 could tell looking at it. It's like the po of 0:11:41.240 --> 0:11:43.800 what it will be one day, you know, because it's 0:11:43.960 --> 0:11:48.000 it's kind of jittery, it's um, the edges aren't clear. 0:11:48.679 --> 0:11:50.480 You can when you're holding one of those balls. You 0:11:50.480 --> 0:11:53.040 can still see your fingers through on the other side, 0:11:53.440 --> 0:11:56.679 but like there's a virtual ball and you're picking it 0:11:56.800 --> 0:11:59.360 up and like throwing it from hand to hand, and 0:11:59.400 --> 0:12:02.760 it's reacting to you like it's there, but it's not there. 0:12:02.800 --> 0:12:06.720 And I mean that's an enormous lead forward. It's pretty wicked. UM. 0:12:06.840 --> 0:12:10.080 Right now, it's a research project, so they're not gonna 0:12:10.120 --> 0:12:12.680 like roll this out anytime soon. But the stuff you 0:12:12.720 --> 0:12:15.840 see in movies of the future where like a surgeon 0:12:15.880 --> 0:12:18.520 will take a model of a heart and you know, 0:12:18.640 --> 0:12:20.960 a holographic model and moving around with his hand or 0:12:21.000 --> 0:12:24.200 something like that's coming down the pike at some point. Um. 0:12:24.720 --> 0:12:29.439 Training surgeons is one application. Training soldiers is another. UM. 0:12:30.000 --> 0:12:32.760 When I was doing the research in the article for PTSD, 0:12:32.920 --> 0:12:36.400 which we need to do eventually, it's just gonna be 0:12:36.440 --> 0:12:38.800 like there's a lot to it. Is we have that 0:12:38.880 --> 0:12:43.160 source who like keeps sending us like research up to 0:12:43.240 --> 0:12:45.880 the date research, um, and yeah, we need to do 0:12:45.920 --> 0:12:48.840 it anyway. UM. I found that one way that they 0:12:48.840 --> 0:12:52.559 were trying to prevent PTSD later on was immersing soldiers 0:12:52.559 --> 0:12:55.640 and like basically what they were gonna see like dead 0:12:55.679 --> 0:13:00.000 bodies handled. It's just horrible stuff. Yeah, beforehand, it's part 0:13:00.000 --> 0:13:02.680 of their training. Interesting, but it looked a lot like 0:13:02.840 --> 0:13:05.800 a current video game now, which is good, but it's 0:13:05.800 --> 0:13:08.520 not really lifelike. If you could nail this and have 0:13:08.640 --> 0:13:11.360 somebody immersed in it, then all of a sudden, like 0:13:12.040 --> 0:13:15.079 they're going to see what they're going to experience, and 0:13:15.120 --> 0:13:17.079 maybe it's kind of like easing them into it a 0:13:17.080 --> 0:13:19.840 little bit to prevent PTSD further down the road. Interesting, 0:13:19.840 --> 0:13:23.240 so like desensitizing them beforehand. Well, that have to be 0:13:23.280 --> 0:13:28.160 pretty real though. I imagine even the realist projection, when 0:13:28.160 --> 0:13:31.160 you still see the real thing, it's like, I don't know, 0:13:32.480 --> 0:13:35.600 I imagine that's still pretty bad. Sure, it's like missing something. 0:13:35.679 --> 0:13:38.920 It's like interacting with a robot. It's missing something. Even 0:13:38.920 --> 0:13:42.640 the greatest robot is missing. Yeah, it could maybe prime 0:13:42.679 --> 0:13:45.040 your brain to see the real thing. At the very least, 0:13:45.120 --> 0:13:48.160 even if it doesn't work to prevent PTSD, they'll make 0:13:48.200 --> 0:13:51.600 a lot a lot of money. It's making video games 0:13:51.640 --> 0:13:53.640 like that, like using it as a straight up video game. 0:13:53.720 --> 0:13:56.120 I think that's one of the big goals of tele immersion, 0:13:56.720 --> 0:14:00.719 is to create a virtual world that you are interacting with, 0:14:00.760 --> 0:14:04.720 Like look at the Microsoft connect the little bar that 0:14:04.760 --> 0:14:07.160 tracks your movements. So now you can like dance and 0:14:07.240 --> 0:14:11.000 like the little avatar and the screen is making your movements. Right. 0:14:11.120 --> 0:14:13.880 You've been to the mall and seeing people doing this? Right? Yeah? 0:14:14.080 --> 0:14:15.840 I think so I know what you're talking about. So 0:14:15.920 --> 0:14:18.240 what have you seen, like people just dancing in the 0:14:18.280 --> 0:14:20.080 middle of the mall in front of the TV screen? No? 0:14:20.160 --> 0:14:23.240 But is it like we fit very much? Okay? Um, 0:14:23.280 --> 0:14:25.560 but I think Microsoft is the one who really had 0:14:25.600 --> 0:14:28.840 the breakthrough with this connect gotch um. So they they've 0:14:28.880 --> 0:14:31.880 got that, They've got tracking human motion down. Yeah. Now 0:14:31.880 --> 0:14:33.280 all they have to do is make it so that 0:14:33.360 --> 0:14:36.840 you're not looking at a screen, you're in the screen. Yeah, 0:14:37.080 --> 0:14:40.040 that's the tele imersion part. Yeah, and the whole um 0:14:40.280 --> 0:14:42.240 hubbub we were talking about with being able to hug 0:14:42.360 --> 0:14:47.200 something for with the hollow deck with Microsoft, like you're 0:14:47.240 --> 0:14:51.080 you're juggling these invisible balls, these holographic balls, but you 0:14:51.120 --> 0:14:55.880 can't feel them. Um. But with something called haptics tectic sensors, 0:14:56.360 --> 0:14:59.160 potentially you might be able to at least replicate some 0:14:59.240 --> 0:15:03.800 of this. Um it is uh tactile feedback technology. So 0:15:04.440 --> 0:15:06.840 if you ever played like PS three, now they have 0:15:06.960 --> 0:15:10.600 the vibrating controllers. Yeah, that's one. So like when you 0:15:10.600 --> 0:15:12.160 get shot or you shoot a guy or something in 0:15:12.200 --> 0:15:14.760 the first person shooter at like vibrates. They also have 0:15:14.840 --> 0:15:17.240 them so that like you can you get little shocks 0:15:17.680 --> 0:15:21.920 to stimulate your sense of touch really to simulate pressure, 0:15:21.960 --> 0:15:25.440 temperature change and basically just screw with your brain. Um. 0:15:25.720 --> 0:15:28.400 So that yeah, then that all of a sudden, now 0:15:28.480 --> 0:15:33.120 hugging would be virtual hugging is like that's I guess 0:15:33.160 --> 0:15:35.640 that would be the holy grail. But it still needs 0:15:35.640 --> 0:15:37.280 to be something physical. So when you have to like 0:15:37.280 --> 0:15:39.680 wear some sort of a suit that's wired to like 0:15:40.240 --> 0:15:45.720 compress like arms around you or m but I mean, 0:15:45.760 --> 0:15:48.960 like we're almost there, and and I don't even know 0:15:49.000 --> 0:15:51.160 if you would have to wear I mean a suit 0:15:51.200 --> 0:15:53.400 would probably be helpful, but I'll bet there's little like 0:15:53.480 --> 0:15:56.280 patches of your skin where if you're wired into that 0:15:57.160 --> 0:15:59.720 and you electrocute those, you could simulate like your whole 0:15:59.800 --> 0:16:02.280 arm feeling a sensation rather than just that finger that 0:16:02.360 --> 0:16:04.600 has that electrode array on it. So you're talking about 0:16:04.600 --> 0:16:08.040 plugging in very much so, and that's the haptic part 0:16:08.040 --> 0:16:10.760 of it. And I think we're already starting to get 0:16:10.800 --> 0:16:15.080 there like some of the some smartphones have like this. 0:16:15.080 --> 0:16:17.600 This haptic effect or is what it's called. The haptic 0:16:17.640 --> 0:16:22.200 sensor senses you squeezing something, and the haptic effect or 0:16:22.600 --> 0:16:26.359 would be the array on the person's arm that simulated 0:16:26.520 --> 0:16:29.680 the pressure of that squeeze. In between, you have a 0:16:29.720 --> 0:16:34.920 lot of information being measured and crunched and transmitted because 0:16:35.000 --> 0:16:37.800 you know how much pressure are you applying, like are 0:16:37.800 --> 0:16:40.000 you trying to hurt the person? Like that? All that 0:16:40.040 --> 0:16:43.360 has to be tracked and then sent and sent out 0:16:43.360 --> 0:16:45.800 to the effect or which replicates it. Well, you want 0:16:45.840 --> 0:16:48.880 it to be exact right, otherwise it's just clumsy, sure, 0:16:49.080 --> 0:16:52.600 or it hurts. That's a good point. It's like, stop squeeze, 0:16:52.640 --> 0:16:56.200 it's hard. I'm not it's the machine. You always say that. 0:16:56.360 --> 0:17:00.280 I know. Uh, the two pack hologram. Yeah, um, I 0:17:00.280 --> 0:17:02.960 looked up. Actually, the NPR did a great story on 0:17:03.000 --> 0:17:05.000 how that was done. But I think I should just 0:17:05.040 --> 0:17:07.359 read real quickly what one of the designers um. He 0:17:07.400 --> 0:17:10.320 sort of explains it by saying sort of a lot. 0:17:10.920 --> 0:17:13.240 He's one of those guys. Uh. He said. There's an 0:17:13.280 --> 0:17:16.960 overhead projector that sort of reflects down onto basically a 0:17:16.960 --> 0:17:19.560 tilted piece of glass that's sort of on the stage floor. 0:17:20.040 --> 0:17:24.520 Then uh, that reflects the well reflection onto a milar 0:17:24.640 --> 0:17:27.439 sort of screen and it sort of projects in this 0:17:27.480 --> 0:17:29.800 sort of three D kind of thing where it allows 0:17:29.800 --> 0:17:32.040 the other performers to sort of walk in front of 0:17:32.080 --> 0:17:35.280 Tupac and basically interact with him. And he said sort 0:17:35.280 --> 0:17:40.919 of literally like six times. But that's a pretty basic 0:17:41.000 --> 0:17:44.480 way of explaining how hologram works. But we have a 0:17:44.520 --> 0:17:48.000 really detailed article on that if we ever feel squirrely holograms. Yeah, 0:17:48.000 --> 0:17:50.119 Tracy wrote it and it's I tried to read it 0:17:50.160 --> 0:17:52.560 today and it flew way over my head. So it's 0:17:52.560 --> 0:17:55.600 gonna require some more effort. That and Blood is going 0:17:55.680 --> 0:17:58.200 to require like a lot of effort that we should 0:17:58.200 --> 0:18:01.720 That should be our last podcast ever. Yeah, and we 0:18:01.760 --> 0:18:04.280 should just like at the same time, cut each other's 0:18:04.320 --> 0:18:08.800 jackulars and flee out on cameras and you got anything else. Oh, 0:18:08.960 --> 0:18:12.760 tele immersion is still going on, yeah, um at Berkeley. 0:18:13.160 --> 0:18:16.400 Berkeley has a big tele immersion lamb you see Berkeley, 0:18:17.080 --> 0:18:22.560 not the music school, same school though, mm hmmmm, Berkeley 0:18:22.560 --> 0:18:26.160 School of Music. That's it. Um, that's like in Massachusetts. Yeah, 0:18:26.480 --> 0:18:29.200 I didn't know that Massachusetts. Yeah, I think it's around Boston. 0:18:29.320 --> 0:18:31.120 I feel like a dummy. Now. Oh it's okay, man, 0:18:31.200 --> 0:18:33.880 and it's not related to Berkeley in California at all. 0:18:34.560 --> 0:18:37.760 I don't believe, so I will. It's all right. Sometimes 0:18:37.760 --> 0:18:41.359 you're swinging thiss, but you look good doing it. I 0:18:41.480 --> 0:18:44.959 appreciate it. Um. Can we be done talking about this? 0:18:45.280 --> 0:18:50.160 I think so? Look for um realistic holographic video conferencing 0:18:50.160 --> 0:18:52.960 in an office near you in the future. In seven years, 0:18:53.320 --> 0:18:56.680 your boss in Japan will be hugging you just because 0:18:56.680 --> 0:19:01.399 he can. Yeah. All right, Well, if you want to 0:19:01.480 --> 0:19:06.760 learn more about virtual environments or holographs or holodecks, you 0:19:06.800 --> 0:19:09.480 can type any of those words into the search bar 0:19:09.560 --> 0:19:12.200 at how stuff works dot com. See what comes up, 0:19:12.600 --> 0:19:16.120 spin the wheel, take your chances, and then just read 0:19:16.160 --> 0:19:19.400 them all. There you go, I said, search bar, Yes, 0:19:19.640 --> 0:19:24.200 so do it, Josh, I'm gonna call this email from 0:19:24.200 --> 0:19:28.959 or Ol buddy Lance Spangler. Oh him, he was, Um, 0:19:29.480 --> 0:19:32.240 he's in the military. Okay, rights all the time. Yes, 0:19:32.359 --> 0:19:36.320 I remember, get hats from him. I don't remember. I 0:19:36.359 --> 0:19:39.840 think our traditional Afghani tribal heads. How was that for him? 0:19:39.880 --> 0:19:42.520 I believe so? If not, we're gonna hear about it. 0:19:42.920 --> 0:19:46.320 Josh and Chuck in your production assistant, and I was 0:19:46.359 --> 0:19:48.159 not talking about Jerry. I think he thinks we actually 0:19:48.160 --> 0:19:51.760 have like a team working for us, which is funny 0:19:51.760 --> 0:19:54.239 in itself. It is we've got Uncle Merle. Let's take 0:19:54.280 --> 0:19:57.000 a source. Sharp Pick always crack up when people email me, 0:19:57.040 --> 0:20:00.760 They're like, whoever entranses were? Josh and Chuck? Yeah, I 0:20:00.800 --> 0:20:04.520 wish Um. I first discovered y'all while working in Iraq 0:20:04.600 --> 0:20:08.040 several years ago and continue to listen to everything you do. Um. 0:20:08.119 --> 0:20:10.800 You even sent me some stickers in two T shirts 0:20:10.800 --> 0:20:13.320 back then. The stickers are no doubt still stuck to 0:20:13.359 --> 0:20:16.720 a number of buildings from Baghdad to Kuwait. I love 0:20:16.800 --> 0:20:21.320 that you missed one testing method, however, in your nuclear devices. 0:20:21.640 --> 0:20:25.320 In your most recent podcasts, Um, remember we talked about 0:20:25.560 --> 0:20:29.800 underground outer space and what in the water and yeah 0:20:30.000 --> 0:20:32.879 yeah what is currently the world's fastest computer located in 0:20:32.880 --> 0:20:35.320 California has been contracted by the d O E and 0:20:35.400 --> 0:20:40.200 d O D to run simulations on each device's output 0:20:40.600 --> 0:20:44.440 real life versus the estimated design output. The computer is 0:20:44.480 --> 0:20:47.600 powerful enough that it models the simulators at the sub 0:20:47.640 --> 0:20:50.960 atomic level. Each sub atomic particle from beginning to end 0:20:51.040 --> 0:20:56.280 is represented that it's crazy because our nuclear arsenal is aging. 0:20:56.560 --> 0:20:59.240 Some weapons are twenty five plus years old. That is 0:20:59.280 --> 0:21:02.959 kind of crazy, uh, in any number of treaty restrictions. Uh. 0:21:03.760 --> 0:21:06.080 These simulations are the perfect way to test the device 0:21:06.119 --> 0:21:09.639 without any nuclear fallout. Even more interesting, these simulations have 0:21:09.760 --> 0:21:14.240 uncovered some surprises, some good, others not so good. I 0:21:14.280 --> 0:21:18.240 guess he's gonna keep this private, right, um, but last 0:21:18.280 --> 0:21:20.640 you think this computer is just a mushroom cloud in disguise. 0:21:20.680 --> 0:21:24.520 They're also modeling the human heart at the cellular level, um, 0:21:24.560 --> 0:21:27.560 each individual cell. That is, to determine the effects of 0:21:27.640 --> 0:21:30.879 various drugs and diseases. All and I'll keep up the 0:21:30.880 --> 0:21:33.560 great work in what you're doing. And as an old 0:21:33.600 --> 0:21:36.359 television producer, knock them dead with the new TV show. 0:21:36.560 --> 0:21:39.119 Thank you. What an interesting project to be a part of. 0:21:39.240 --> 0:21:41.760 And with the kind of brand awareness and the following 0:21:41.800 --> 0:21:44.040 you have, it's sure to be a success. And that 0:21:44.200 --> 0:21:47.640 is from our old buddy Lance Spangler in Castle Rock, Colorado, 0:21:48.000 --> 0:21:51.440 who hopefully um knocked on wood with that last sentence. 0:21:52.040 --> 0:21:55.119 We're knocking now just in case. Yeah, UM, thank you 0:21:55.240 --> 0:21:59.000 very much, Lance. I won't I don't know if you 0:21:59.160 --> 0:22:01.960 saw me sending the hats are not well. I definitely 0:22:02.000 --> 0:22:04.760 remember that we sent him stickers and shirts and now 0:22:04.760 --> 0:22:07.120 they're in baghday and I believe he might have sent 0:22:07.520 --> 0:22:10.280 a picture back of them wearing the shirts, but that 0:22:10.359 --> 0:22:12.720 might have been another year. Right. But then we have 0:22:12.760 --> 0:22:15.840 another guy who's taking who took pictures of the flint 0:22:15.880 --> 0:22:20.720 Stone Amusement park in Baghdad. Oh yeah he I think 0:22:20.720 --> 0:22:22.000 he was the one who sent us the hat that 0:22:22.080 --> 0:22:26.520 was awesome off to all our military listeners. Afghany hats off. Uh, 0:22:26.680 --> 0:22:30.439 let's see if you have a correction or uh like 0:22:30.680 --> 0:22:36.920 lance head just a I guess a mind blowing add Yes, 0:22:37.080 --> 0:22:40.680 thank you, Chuck, because I was really having trouble there. Um. 0:22:40.760 --> 0:22:43.320 You can tweet it to us at s Y s 0:22:43.359 --> 0:22:46.840 K podcast. You can join us on Facebook dot com 0:22:47.000 --> 0:22:50.280 slash stuff you should don't.
