Speaker 1: Welcome to you stuff you should know from house Stuff
Speaker 1: Works dot com. Hey, and welcome to the podcast. I'm
Speaker 1: Josh Clark. There's Charles W. Chuck Bryant that makes this stuff.
Speaker 1: You snow. Jerry's back there. We're all set got our
Speaker 1: Mike's got the dinosaur. What's this dinosaur's name? Frank the chairs?
Speaker 1: Uncle is here year old uncle who's in the Olympics,
Speaker 1: Uncle Merle, the Frank the chair. His uncle Merle is
Speaker 1: the dinosaur. Oh I was talking about the chairs sitting in?
Speaker 1: Is that a nameless Oh yeah, this isn't Frank. Is
Speaker 1: it Frank's on set at our TV show that we're shooting,
Speaker 1: unfortunately with a TV show we're making. Is that set in? Uh? Yeah,
Speaker 1: it's set in that I had to sit in that
Speaker 1: stupid chair for sixty hours a couple of weeks ago. Yeah,
Speaker 1: it's hilarious. Yeah, they followed us there. Uh okay, So
Speaker 1: this is Uncle Merle the dinosaur, the stegasaurs. I believe sure.
Speaker 1: It's like a stack of source cross with a sharp
Speaker 1: pay Look at all those wrinkles. That's about it, all right.
Speaker 1: If you want to get in touch with us, hey, buddy,
Speaker 1: if you don't mind if I plug my November page
Speaker 1: real quick, please do. I am growing a mustache this
Speaker 1: month for November for uh for cancer research, specifically male
Speaker 1: prostate cancer research. That's right. And you can donate to
Speaker 1: my team, which would be pretty cool because you know,
Speaker 1: you get a free podcast and it'd be nice to
Speaker 1: throw a little money towards cancer research. Being nice here,
Speaker 1: give him some money. He's growing out facial here to
Speaker 1: help a charitable organization engage in really important scientific research.
Speaker 1: That's right. And you can go to mobro dot c
Speaker 1: O slash Charles Bryant and that's my page, or just
Speaker 1: go to the November site. Type in Charles Bryan in
Speaker 1: the search bar and look for the picture of me.
Speaker 1: There's only a couple of us out there. Chuck's wearing
Speaker 1: a red shirt. It's yeah, um, so what is that again?
Speaker 1: That's mo bro dot CEO slash Charles Bryant. Yes, thank
Speaker 1: you in advance. Yeah, that's nice, Chuck. All right, let's
Speaker 1: get to it. Chuck, you selected this one. How do
Speaker 1: you feel it sounded a lot cooler? Yeah. We're talking
Speaker 1: about holographic environments. Yeah, and you hear that you think
Speaker 1: Man Star Trek. Yeah, it comes to life. So I
Speaker 1: wanted to make sure I knew what I was talking about,
Speaker 1: and I went and looked up the holidack. Yeah, and
Speaker 1: it's apparently just from the next generation, like it wasn't
Speaker 1: like original. I didn't see anything. I even looked on
Speaker 1: a Star Trek wiki and it's it seemed to indicate
Speaker 1: the first I'm so nervous right now. Well let's say this.
Speaker 1: We'll find out one way or the other very quickly.
Speaker 1: But it seemed to indicate from my cursory research that
Speaker 1: the holidack was a feature on the Enterprise from the
Speaker 1: twenty three sixties e g. Or I e. The next generation.
Speaker 1: All right, so what it was? The hollow deck? Have
Speaker 1: you seen it? Are you familiar? Star Trek cital? And
Speaker 1: now I was in a Star Trek guy. I mean,
Speaker 1: it just kind of got past me. But have you
Speaker 1: seen it? Did you? Did you see it? Yeah? Okay,
Speaker 1: it's cool. You know, it is a projection, a holographic
Speaker 1: projection room, and basically, you know, is what you would think.
Speaker 1: You know, remember in Star Wars, which I am a
Speaker 1: fan of, when our two D two spit out the
Speaker 1: little holographic image of Princess Leiah rendering her message. Um,
Speaker 1: imagine a room of life sized people doing that as
Speaker 1: if you're interacting. Yes, that's a very important key, um,
Speaker 1: because what we're talking about is not just a three
Speaker 1: D projection like Star Wars clunked along with. But we're
Speaker 1: talking about the Star Trek holographic environment where you can
Speaker 1: move around and you get a three D and sixty
Speaker 1: degree view and you can shake hands and maybe uh,
Speaker 1: have a cocktail or play a trombone or something with
Speaker 1: someone else in a virtual environment. But you can interact
Speaker 1: like you don't like when you walk around the backside
Speaker 1: of somebody. It's not you're not getting in the way
Speaker 1: of the projector. Can I read a line from the article? Yes,
Speaker 1: eventually you will even be able to hug other people
Speaker 1: using this technology. They should have put hug in quotes
Speaker 1: because because it's not a hug, No, they're not really there.
Speaker 1: Oh I meant I thought that they were talking about
Speaker 1: like having virtual sex. Of course, it's going to go
Speaker 1: to virtual sex. It's gonna be the first thing that
Speaker 1: they come up with. That's what everybody at Microsoft is
Speaker 1: working on right now. I'm quite sure you'll make a
Speaker 1: trillion dollars it's like, uh, is it total recall? Ah, yeah,
Speaker 1: where you had the three D or virtual reality experiences. Yeah,
Speaker 1: and I'm sure it's been another stuff too. I'm not
Speaker 1: thinking of like total recall the remake. Yeah, that was
Speaker 1: the other thing I was thinking of. All right, what
Speaker 1: we're talking about telet immersion. That's the real name for it, yes,
Speaker 1: not the holidack, And it right now is mainly being
Speaker 1: um developed for a few different things, potentially video game use, hugging,
Speaker 1: hugging your family members at Christmas, yeah you can't be there, um,
Speaker 1: but mainly for uh, something that's not quite as exciting
Speaker 1: video conferencing, right which we've seen like the pinnacle of
Speaker 1: video conferencing right now, I think so, Yeah, man, they
Speaker 1: owe us a couple of bucks. Yeah, we've plugged them
Speaker 1: like heavily. Well, I mean it's amazing technology, it is,
Speaker 1: but it's it's just like nothing compared to teleimersion. Yeah,
Speaker 1: goal of true. And this article is has got to
Speaker 1: be outdated, because laughably out of date because after witnessing
Speaker 1: the Tanburg in use, which basically feels like you're sitting
Speaker 1: in a room, you know, it's HD It's not like
Speaker 1: a hologram or three D or anything. But it's really
Speaker 1: good and it feels like you're sitting in a room
Speaker 1: with someone. There's no lag, there's no stuttering. And this
Speaker 1: article talks about like these days, you know, there's some
Speaker 1: stuttering and flickering when you try to teleconference. Right, they
Speaker 1: figured that all out, they did. Um. They also this
Speaker 1: article you know, this article also no it's not but
Speaker 1: which I mean, like it's kind of I think where
Speaker 1: the tele immersion was at when this article was written.
Speaker 1: Where we're at with like it's pretty decent now, you know.
Speaker 1: But the the the author Kevin Bondser makes a point
Speaker 1: like if you walk out of the way of the webcam,
Speaker 1: nobody can see you any longer if you are um,
Speaker 1: like when you're looking at the computer screen, the webcams
Speaker 1: getting your eyes, but you're not making eye contact, like
Speaker 1: nobody thinks to do that. That's all this stuff just
Speaker 1: kind of goes away with tele immersion. Um, because you
Speaker 1: have a webcam that's tracking your eyes to see where
Speaker 1: you're where you're looking at. That's a big part of it.
Speaker 1: Facial recognition helps with that too, and then also there's
Speaker 1: a camera ray. It's not just one webcam pointing at you.
Speaker 1: Your there's cameras around you, but pretty much three D
Speaker 1: and sixty degrees, so there capturing everything you're doing. So
Speaker 1: you can't leave the the view of the other person. Yeah,
Speaker 1: you have to go into a different room and then
Speaker 1: what you know, what's the point? Hang up? Your call
Speaker 1: is over at that point, unless you just have to
Speaker 1: be real quick and you're like, hold on, I'll be
Speaker 1: right back. Um. One thing that's in the way right now.
Speaker 1: I mean, they made a lot of headway that this
Speaker 1: article points out in two thousand, twelve years ago is
Speaker 1: when they made their first big breakthrough. Um uh, the
Speaker 1: National telet Immersion Initiative. Yes, working together Chapel Hill looks
Speaker 1: like North Carolina. Did you look up this group? Are
Speaker 1: they still around? Their websites still around? But they reached
Speaker 1: their pinnacle in May two thousand. Is it my space? Oh? Man,
Speaker 1: yeah it is. And it's like what we're doing two thousand? Nothing? Nothing?
Speaker 1: All right? Well, at the time, it was a big
Speaker 1: breakthrough because it was the first time they were able
Speaker 1: to see three dimensional holographic images of like colleagues in
Speaker 1: different cities. Yeah, all sitting in the same room, right,
Speaker 1: And it was a big deal. Yeah, and that's we
Speaker 1: should also say, like the point of telemersion is basically
Speaker 1: to create say if you want to telecommunity and you
Speaker 1: have a conference, rather than everybody flying to the conference room,
Speaker 1: you have a virtual conference room set up to where
Speaker 1: everybody basically projects himself into this shared space, the shared
Speaker 1: room that you can get up and move around and
Speaker 1: see from different angles and um, each user is depicted
Speaker 1: three D and sixty degrees. So it it is a
Speaker 1: sort of telepresence, is what they call it. Yeah, and
Speaker 1: it's sort of a green initiative to you could look
Speaker 1: at it that way. Yeah, save a lot on jet
Speaker 1: fuel and commuting costs, and that there's some huge challenges
Speaker 1: to this there we're back in two thousand and it's um,
Speaker 1: a lot of them are still around. One of them
Speaker 1: is the kind of bandwidth that we will need because
Speaker 1: I think it's said for the frame to refresh itself
Speaker 1: um at ten, or the screen to refresh itself, or
Speaker 1: the projection to refresh it time frames a second, that'd
Speaker 1: be seamless, but it was hitting at like three back
Speaker 1: in two thousand. I wonder what is that now. I'm
Speaker 1: sure that we can do that now, but the problem is, um,
Speaker 1: transmitting that data right is problematic, shuts up a lot
Speaker 1: of bandwidth. Yeah. So you're talking about two things. A
Speaker 1: computers that are way more juiced than they are now
Speaker 1: even now, and you're talking about an internet um from
Speaker 1: my internet to basically yeah, now that's still going on, right,
Speaker 1: it's um basically this initiative by a bunch of universities
Speaker 1: around the country to wire the US at speeds that
Speaker 1: are just blistering fast compared to what we've got now,
Speaker 1: up to a thousand times faster. That's really really fast. Um.
Speaker 1: They also have enormous storage capabilities, and I saw one
Speaker 1: of the things that they're doing is using this to
Speaker 1: move out to underserved areas of the country. Oh really, Yeah,
Speaker 1: it's not just like just it's not just for New
Speaker 1: York or Francisco. It's like, yeah, it's for North Dakota.
Speaker 1: Why can't North Dakota get online? Finally, that's funny. Uh
Speaker 1: but true. You also have UM, well just basically tracking somebody,
Speaker 1: which Microsoft has done a lot to get past. Are
Speaker 1: you talking about that new thing, the hollow desk? Yes, yeah,
Speaker 1: I just found this today. Did you look at that
Speaker 1: the video? Yeah, it's pretty cool. Microsoft is developing something
Speaker 1: and this is current UM called the hollow desk, and
Speaker 1: UM he uses an overhead screen to project a two
Speaker 1: D two D image through a half silvered beam splitter
Speaker 1: onto a desktop. Basically, what it looks like is, UM,
Speaker 1: it looks like you're working on a desk with a
Speaker 1: screen between you and the desk. I can see through
Speaker 1: clear screen. Yeah, so if you look below that screen,
Speaker 1: you're just gonna see your hands doing nothing. If you
Speaker 1: look through that screen, you're gonna see holographic images. In
Speaker 1: this case, there were like little glowing balls that you
Speaker 1: could pick up and juggle, and you could pick it
Speaker 1: up with a piece of paper. You could put it
Speaker 1: in a coffee cup and swirl it around. Pretty cool. Yeah,
Speaker 1: that's huge. That's hugely different than anything that this article
Speaker 1: was talking about or anything we thought of before, because
Speaker 1: like you're interacting with a virtual environment. It's reacting to you.
Speaker 1: I mean, yeah, super advanced. And it was like you
Speaker 1: could tell looking at it. It's like the po of
Speaker 1: what it will be one day, you know, because it's
Speaker 1: it's kind of jittery, it's um, the edges aren't clear.
Speaker 1: You can when you're holding one of those balls. You
Speaker 1: can still see your fingers through on the other side,
Speaker 1: but like there's a virtual ball and you're picking it
Speaker 1: up and like throwing it from hand to hand, and
Speaker 1: it's reacting to you like it's there, but it's not there.
Speaker 1: And I mean that's an enormous lead forward. It's pretty wicked. UM.
Speaker 1: Right now, it's a research project, so they're not gonna
Speaker 1: like roll this out anytime soon. But the stuff you
Speaker 1: see in movies of the future where like a surgeon
Speaker 1: will take a model of a heart and you know,
Speaker 1: a holographic model and moving around with his hand or
Speaker 1: something like that's coming down the pike at some point. Um.
Speaker 1: Training surgeons is one application. Training soldiers is another. UM.
Speaker 1: When I was doing the research in the article for PTSD,
Speaker 1: which we need to do eventually, it's just gonna be
Speaker 1: like there's a lot to it. Is we have that
Speaker 1: source who like keeps sending us like research up to
Speaker 1: the date research, um, and yeah, we need to do
Speaker 1: it anyway. UM. I found that one way that they
Speaker 1: were trying to prevent PTSD later on was immersing soldiers
Speaker 1: and like basically what they were gonna see like dead
Speaker 1: bodies handled. It's just horrible stuff. Yeah, beforehand, it's part
Speaker 1: of their training. Interesting, but it looked a lot like
Speaker 1: a current video game now, which is good, but it's
Speaker 1: not really lifelike. If you could nail this and have
Speaker 1: somebody immersed in it, then all of a sudden, like
Speaker 1: they're going to see what they're going to experience, and
Speaker 1: maybe it's kind of like easing them into it a
Speaker 1: little bit to prevent PTSD further down the road. Interesting,
Speaker 1: so like desensitizing them beforehand. Well, that have to be
Speaker 1: pretty real though. I imagine even the realist projection, when
Speaker 1: you still see the real thing, it's like, I don't know,
Speaker 1: I imagine that's still pretty bad. Sure, it's like missing something.
Speaker 1: It's like interacting with a robot. It's missing something. Even
Speaker 1: the greatest robot is missing. Yeah, it could maybe prime
Speaker 1: your brain to see the real thing. At the very least,
Speaker 1: even if it doesn't work to prevent PTSD, they'll make
Speaker 1: a lot a lot of money. It's making video games
Speaker 1: like that, like using it as a straight up video game.
Speaker 1: I think that's one of the big goals of tele immersion,
Speaker 1: is to create a virtual world that you are interacting with,
Speaker 1: Like look at the Microsoft connect the little bar that
Speaker 1: tracks your movements. So now you can like dance and
Speaker 1: like the little avatar and the screen is making your movements. Right.
Speaker 1: You've been to the mall and seeing people doing this? Right? Yeah?
Speaker 1: I think so I know what you're talking about. So
Speaker 1: what have you seen, like people just dancing in the
Speaker 1: middle of the mall in front of the TV screen? No?
Speaker 1: But is it like we fit very much? Okay? Um,
Speaker 1: but I think Microsoft is the one who really had
Speaker 1: the breakthrough with this connect gotch um. So they they've
Speaker 1: got that, They've got tracking human motion down. Yeah. Now
Speaker 1: all they have to do is make it so that
Speaker 1: you're not looking at a screen, you're in the screen. Yeah,
Speaker 1: that's the tele imersion part. Yeah, and the whole um
Speaker 1: hubbub we were talking about with being able to hug
Speaker 1: something for with the hollow deck with Microsoft, like you're
Speaker 1: you're juggling these invisible balls, these holographic balls, but you
Speaker 1: can't feel them. Um. But with something called haptics tectic sensors,
Speaker 1: potentially you might be able to at least replicate some
Speaker 1: of this. Um it is uh tactile feedback technology. So
Speaker 1: if you ever played like PS three, now they have
Speaker 1: the vibrating controllers. Yeah, that's one. So like when you
Speaker 1: get shot or you shoot a guy or something in
Speaker 1: the first person shooter at like vibrates. They also have
Speaker 1: them so that like you can you get little shocks
Speaker 1: to stimulate your sense of touch really to simulate pressure,
Speaker 1: temperature change and basically just screw with your brain. Um.
Speaker 1: So that yeah, then that all of a sudden, now
Speaker 1: hugging would be virtual hugging is like that's I guess
Speaker 1: that would be the holy grail. But it still needs
Speaker 1: to be something physical. So when you have to like
Speaker 1: wear some sort of a suit that's wired to like
Speaker 1: compress like arms around you or m but I mean,
Speaker 1: like we're almost there, and and I don't even know
Speaker 1: if you would have to wear I mean a suit
Speaker 1: would probably be helpful, but I'll bet there's little like
Speaker 1: patches of your skin where if you're wired into that
Speaker 1: and you electrocute those, you could simulate like your whole
Speaker 1: arm feeling a sensation rather than just that finger that
Speaker 1: has that electrode array on it. So you're talking about
Speaker 1: plugging in very much so, and that's the haptic part
Speaker 1: of it. And I think we're already starting to get
Speaker 1: there like some of the some smartphones have like this.
Speaker 1: This haptic effect or is what it's called. The haptic
Speaker 1: sensor senses you squeezing something, and the haptic effect or
Speaker 1: would be the array on the person's arm that simulated
Speaker 1: the pressure of that squeeze. In between, you have a
Speaker 1: lot of information being measured and crunched and transmitted because
Speaker 1: you know how much pressure are you applying, like are
Speaker 1: you trying to hurt the person? Like that? All that
Speaker 1: has to be tracked and then sent and sent out
Speaker 1: to the effect or which replicates it. Well, you want
Speaker 1: it to be exact right, otherwise it's just clumsy, sure,
Speaker 1: or it hurts. That's a good point. It's like, stop squeeze,
Speaker 1: it's hard. I'm not it's the machine. You always say that.
Speaker 1: I know. Uh, the two pack hologram. Yeah, um, I
Speaker 1: looked up. Actually, the NPR did a great story on
Speaker 1: how that was done. But I think I should just
Speaker 1: read real quickly what one of the designers um. He
Speaker 1: sort of explains it by saying sort of a lot.
Speaker 1: He's one of those guys. Uh. He said. There's an
Speaker 1: overhead projector that sort of reflects down onto basically a
Speaker 1: tilted piece of glass that's sort of on the stage floor.
Speaker 1: Then uh, that reflects the well reflection onto a milar
Speaker 1: sort of screen and it sort of projects in this
Speaker 1: sort of three D kind of thing where it allows
Speaker 1: the other performers to sort of walk in front of
Speaker 1: Tupac and basically interact with him. And he said sort
Speaker 1: of literally like six times. But that's a pretty basic
Speaker 1: way of explaining how hologram works. But we have a
Speaker 1: really detailed article on that if we ever feel squirrely holograms. Yeah,
Speaker 1: Tracy wrote it and it's I tried to read it
Speaker 1: today and it flew way over my head. So it's
Speaker 1: gonna require some more effort. That and Blood is going
Speaker 1: to require like a lot of effort that we should
Speaker 1: That should be our last podcast ever. Yeah, and we
Speaker 1: should just like at the same time, cut each other's
Speaker 1: jackulars and flee out on cameras and you got anything else. Oh,
Speaker 1: tele immersion is still going on, yeah, um at Berkeley.
Speaker 1: Berkeley has a big tele immersion lamb you see Berkeley,
Speaker 1: not the music school, same school though, mm hmmmm, Berkeley
Speaker 1: School of Music. That's it. Um, that's like in Massachusetts. Yeah,
Speaker 1: I didn't know that Massachusetts. Yeah, I think it's around Boston.
Speaker 1: I feel like a dummy. Now. Oh it's okay, man,
Speaker 1: and it's not related to Berkeley in California at all.
Speaker 1: I don't believe, so I will. It's all right. Sometimes
Speaker 1: you're swinging thiss, but you look good doing it. I
Speaker 1: appreciate it. Um. Can we be done talking about this?
Speaker 1: I think so? Look for um realistic holographic video conferencing
Speaker 1: in an office near you in the future. In seven years,
Speaker 1: your boss in Japan will be hugging you just because
Speaker 1: he can. Yeah. All right, Well, if you want to
Speaker 1: learn more about virtual environments or holographs or holodecks, you
Speaker 1: can type any of those words into the search bar
Speaker 1: at how stuff works dot com. See what comes up,
Speaker 1: spin the wheel, take your chances, and then just read
Speaker 1: them all. There you go, I said, search bar, Yes,
Speaker 1: so do it, Josh, I'm gonna call this email from
Speaker 1: or Ol buddy Lance Spangler. Oh him, he was, Um,
Speaker 1: he's in the military. Okay, rights all the time. Yes,
Speaker 1: I remember, get hats from him. I don't remember. I
Speaker 1: think our traditional Afghani tribal heads. How was that for him?
Speaker 1: I believe so? If not, we're gonna hear about it.
Speaker 1: Josh and Chuck in your production assistant, and I was
Speaker 1: not talking about Jerry. I think he thinks we actually
Speaker 1: have like a team working for us, which is funny
Speaker 1: in itself. It is we've got Uncle Merle. Let's take
Speaker 1: a source. Sharp Pick always crack up when people email me,
Speaker 1: They're like, whoever entranses were? Josh and Chuck? Yeah, I
Speaker 1: wish Um. I first discovered y'all while working in Iraq
Speaker 1: several years ago and continue to listen to everything you do. Um.
Speaker 1: You even sent me some stickers in two T shirts
Speaker 1: back then. The stickers are no doubt still stuck to
Speaker 1: a number of buildings from Baghdad to Kuwait. I love
Speaker 1: that you missed one testing method, however, in your nuclear devices.
Speaker 1: In your most recent podcasts, Um, remember we talked about
Speaker 1: underground outer space and what in the water and yeah
Speaker 1: yeah what is currently the world's fastest computer located in
Speaker 1: California has been contracted by the d O E and
Speaker 1: d O D to run simulations on each device's output
Speaker 1: real life versus the estimated design output. The computer is
Speaker 1: powerful enough that it models the simulators at the sub
Speaker 1: atomic level. Each sub atomic particle from beginning to end
Speaker 1: is represented that it's crazy because our nuclear arsenal is aging.
Speaker 1: Some weapons are twenty five plus years old. That is
Speaker 1: kind of crazy, uh, in any number of treaty restrictions. Uh.
Speaker 1: These simulations are the perfect way to test the device
Speaker 1: without any nuclear fallout. Even more interesting, these simulations have
Speaker 1: uncovered some surprises, some good, others not so good. I
Speaker 1: guess he's gonna keep this private, right, um, but last
Speaker 1: you think this computer is just a mushroom cloud in disguise.
Speaker 1: They're also modeling the human heart at the cellular level, um,
Speaker 1: each individual cell. That is, to determine the effects of
Speaker 1: various drugs and diseases. All and I'll keep up the
Speaker 1: great work in what you're doing. And as an old
Speaker 1: television producer, knock them dead with the new TV show.
Speaker 1: Thank you. What an interesting project to be a part of.
Speaker 1: And with the kind of brand awareness and the following
Speaker 1: you have, it's sure to be a success. And that
Speaker 1: is from our old buddy Lance Spangler in Castle Rock, Colorado,
Speaker 1: who hopefully um knocked on wood with that last sentence.
Speaker 1: We're knocking now just in case. Yeah, UM, thank you
Speaker 1: very much, Lance. I won't I don't know if you
Speaker 1: saw me sending the hats are not well. I definitely
Speaker 1: remember that we sent him stickers and shirts and now
Speaker 1: they're in baghday and I believe he might have sent
Speaker 1: a picture back of them wearing the shirts, but that
Speaker 1: might have been another year. Right. But then we have
Speaker 1: another guy who's taking who took pictures of the flint
Speaker 1: Stone Amusement park in Baghdad. Oh yeah he I think
Speaker 1: he was the one who sent us the hat that
Speaker 1: was awesome off to all our military listeners. Afghany hats off. Uh,
Speaker 1: let's see if you have a correction or uh like
Speaker 1: lance head just a I guess a mind blowing add Yes,
Speaker 1: thank you, Chuck, because I was really having trouble there. Um.
