WEBVTT - How the Nintendo 3DS Works 0:00:00.320 --> 0:00:02.960 Brought to you by the reinvented two thousand twelve Camray. 0:00:03.200 --> 0:00:09.000 It's ready. Are you get in touch with technology with 0:00:09.080 --> 0:00:17.760 tech Stuff from how stuff works dot com. Hello again, everyone, 0:00:17.840 --> 0:00:20.520 Welcome to tech stuff. My name is Chris Poette and 0:00:20.520 --> 0:00:22.800 I am an editor at how stuff works dot Com. 0:00:22.840 --> 0:00:27.400 Sitting across from me, as always, his senior writer Jonathan Strickland. Great, Yes, 0:00:27.520 --> 0:00:33.320 shot the Invisible Swordsman reverted to movies. That was a quote. 0:00:33.360 --> 0:00:34.880 That was a quote switch up. I had a different 0:00:34.960 --> 0:00:37.519 quote lined up, but then Mr Pellette made a reference 0:00:37.520 --> 0:00:40.080 to a certain movie and I had to follow suit. 0:00:40.720 --> 0:00:43.920 I like silly movies. I love that movie. Man. I 0:00:43.960 --> 0:00:48.160 saw that film at least three times in the theater. Really, yeah, 0:00:48.280 --> 0:00:51.840 well one for each, you know, amigo. And it wasn't 0:00:51.880 --> 0:00:55.960 drown love this time. So, but today we wanted to 0:00:56.000 --> 0:00:58.960 talk about a device that I actually got some hands 0:00:59.000 --> 0:01:03.280 on time with some pretty in depth hands on time 0:01:03.320 --> 0:01:07.680 with the Nintendo three D S. Yes, funny you would say, 0:01:07.840 --> 0:01:10.880 in depth. Yes, let me put it this way. I'm 0:01:10.880 --> 0:01:13.920 not gonna have any more time with that particular device. No, no, 0:01:14.200 --> 0:01:16.440 And uh, you know I actually had a little time 0:01:16.440 --> 0:01:19.319 with that device too. And you said give me that. Yeah, okay, 0:01:19.360 --> 0:01:23.560 so the first time I after that, I'm bitter. Yeah, well, 0:01:23.600 --> 0:01:25.880 I mean, like I said, I'm not playing with it 0:01:25.880 --> 0:01:29.319 anymore either. Um. The first time I laid eyes upon 0:01:29.480 --> 0:01:31.959 the Nintendo three D S was at the two thousand 0:01:32.000 --> 0:01:37.679 and ten E three conference the Electronic Entertainment Expo was 0:01:37.720 --> 0:01:39.440 at the time that when you laid eyes on it, 0:01:39.480 --> 0:01:41.720 where the shaft of light came down from the ceiling 0:01:41.720 --> 0:01:45.039 and the Angel Chorus started singing, except that the angel 0:01:45.080 --> 0:01:48.240 course instead of going oh said it's to me, I'm 0:01:48.240 --> 0:01:52.280 not and yeah, I know the It was a big 0:01:52.320 --> 0:01:55.040 deal at E three. I mean, Nintendo had revealed this 0:01:55.160 --> 0:01:58.000 new hardware. It had been years since Nintendo had done 0:01:58.040 --> 0:02:01.080 something besides the D S light right, it was. It 0:02:01.160 --> 0:02:04.280 wasn't just a simple tweak of the DS. It was 0:02:04.520 --> 0:02:09.080 a pretty major leap forward. Yes, and uh and so 0:02:09.280 --> 0:02:11.120 you can actually see the forward because it's in three 0:02:11.200 --> 0:02:14.280 D exactly. That was the big deal, was glasses free 0:02:14.560 --> 0:02:19.040 three D in this device? Yep. Now, uh yeah, we 0:02:19.320 --> 0:02:21.799 usually say this at the beginning of the podcast such 0:02:21.800 --> 0:02:23.600 as this, but there was so much hype in this 0:02:23.639 --> 0:02:25.880 case that we've had several people asked us to do 0:02:25.919 --> 0:02:27.440 a show in the three D S, so we're happy 0:02:27.480 --> 0:02:31.120 to oblige, so happy in fact that how stuff works 0:02:31.120 --> 0:02:33.320 dot Com actually bought a three D S for us 0:02:33.360 --> 0:02:37.320 to try out because I wasn't at the show, so 0:02:37.360 --> 0:02:38.800 I didn't get to see it for myself. Well, and 0:02:38.840 --> 0:02:40.480 I only got a chance to see it for about 0:02:40.520 --> 0:02:44.320 three minutes because you stood in line for around minutes 0:02:44.360 --> 0:02:46.200 to an hour unless you had a v I P pass. 0:02:46.360 --> 0:02:49.480 So people like seeing that's Brian Tong jumped right to 0:02:49.480 --> 0:02:52.640 the front and people like shlubby old me got in 0:02:52.680 --> 0:02:54.440 line with all the rest of the peons and we 0:02:54.480 --> 0:02:56.680 waited and waited and waited. Dude, why didn't you get 0:02:56.760 --> 0:02:59.760 a fast pass? I don't I know. I know I 0:02:59.800 --> 0:03:01.560 know better by now clearly. I mean I know the 0:03:01.639 --> 0:03:04.720 right people, right, I just apparently I didn't leverage those 0:03:04.760 --> 0:03:08.040 relationships the way I should. My networking skills are are poor. 0:03:08.480 --> 0:03:11.280 So anyway, yeah, we've got a few minutes to look at. 0:03:11.400 --> 0:03:13.600 And it was very impressive that when one of the 0:03:13.639 --> 0:03:17.080 games they showed off was this Mario platform game Go 0:03:17.280 --> 0:03:20.520 Figure U that know, that used the three D in 0:03:20.520 --> 0:03:23.240 a very effective way, and that the three D actually 0:03:23.240 --> 0:03:26.000 was adjustable. There's a slider on the right side of 0:03:26.040 --> 0:03:28.919 the screen. The three D screen, the DS, by the way, 0:03:28.919 --> 0:03:32.240 in case you have not seen one, is a handheld 0:03:32.240 --> 0:03:35.480 gaming device that has two screens. There's the screen that 0:03:35.520 --> 0:03:38.040 you're actually watching for the game and where the game 0:03:38.080 --> 0:03:40.840 action is happening, and then there is a touch screen 0:03:40.920 --> 0:03:44.720 interface system that you may use in the while playing 0:03:44.720 --> 0:03:46.800 a game, or you know, it may just be there 0:03:46.920 --> 0:03:49.840 is a decoration because you may be using the basic 0:03:49.880 --> 0:03:53.680 controls like the game pad and the buttons. Right, and 0:03:53.720 --> 0:03:55.640 it looks a lot like the the D S light, 0:03:56.160 --> 0:03:59.640 which of which I have one um, except that there 0:03:59.640 --> 0:04:02.440 are some some pretty different features. I'm used to the 0:04:02.560 --> 0:04:06.960 typical Nintendo uh four direction D pad, Yes, and it 0:04:07.040 --> 0:04:09.600 has one of those, and yeah, but it also has 0:04:09.600 --> 0:04:13.120 a circular pad, an analog circular pad, so it's like 0:04:13.160 --> 0:04:16.359 a little joystick that your thumb sits on. Yeah, kind of, 0:04:16.440 --> 0:04:19.320 So the three D S kind of up the anti 0:04:19.400 --> 0:04:21.839 with that. But yeah. The the cool thing was that 0:04:21.920 --> 0:04:23.320 the whole idea was that there was going to be 0:04:23.360 --> 0:04:27.719 this this glasses free three D experience And you might 0:04:27.800 --> 0:04:32.400 ask yourself, hey, how does that work? Well, I'll tell you. 0:04:33.160 --> 0:04:38.440 It's based upon a principle called parallax barrier. Now, in 0:04:38.560 --> 0:04:39.880 order for this to make sense, we got to talk 0:04:39.880 --> 0:04:41.960 about a few different concepts. First of all, let's talk 0:04:42.000 --> 0:04:45.000 about parallax. We've talked about this before in other three 0:04:45.120 --> 0:04:48.880 D podcasts as podcast about three D not podcasts, but 0:04:48.920 --> 0:04:51.120 we're in three D. Well they were, but you had 0:04:51.120 --> 0:04:53.920 to have a special kind of earphones to listen to you. 0:04:53.920 --> 0:04:55.599 You kind of had to be here in the studio 0:04:55.640 --> 0:04:57.760 while we recorded it to be at all three dimensional. 0:04:57.800 --> 0:04:59.760 And even then that's stretching it for us. Let's be 0:04:59.800 --> 0:05:04.120 on us. So parallax is based upon the whole idea 0:05:04.200 --> 0:05:07.360 that well, there are different things about parallax, right, but 0:05:07.480 --> 0:05:10.120 as far as three D vision goes, stereoscopic vision goes, 0:05:10.440 --> 0:05:13.320 parallax is based upon the fact that our eyes are 0:05:13.360 --> 0:05:19.680 not located in the same exact spot. Yeah, we would 0:05:19.720 --> 0:05:22.239 be a cyclops. So if if you are a human 0:05:22.240 --> 0:05:27.000 being with two healthy, regular working eyes, then you can 0:05:27.080 --> 0:05:29.919 use parallax to determine how far away an object is 0:05:30.000 --> 0:05:33.120 and part and that's kind of based upon, uh, the 0:05:33.120 --> 0:05:35.240 the distance that the picture that you're getting out of 0:05:35.240 --> 0:05:37.600 your left eye versus the picture you're getting out of 0:05:37.640 --> 0:05:40.560 your right eye. And your brain puts these two pictures 0:05:40.600 --> 0:05:45.719 together into a h an integrated picture. So you know, 0:05:45.760 --> 0:05:48.360 instead of getting instead of you sitting there and perceiving 0:05:48.440 --> 0:05:51.799 two different images, you actually perceive a single image based 0:05:51.839 --> 0:05:54.680 upon these two inputs, these two data inputs that are 0:05:54.720 --> 0:05:57.120 coming in at the same time. And so this is 0:05:57.160 --> 0:06:00.240 part of what helps you with your depth perception. It's 0:06:00.240 --> 0:06:02.440 not the only thing, but it definitely helps. And that 0:06:02.600 --> 0:06:05.880 you know, your brain kind of takes in that information, says, 0:06:05.920 --> 0:06:11.600 based upon this information, that person is so many feet away, right, 0:06:11.880 --> 0:06:14.760 And so three D what three D does because that 0:06:14.920 --> 0:06:18.479 presents you two sets of images. Each eye only receives 0:06:18.640 --> 0:06:22.480 one of those images, one set, and then your brain 0:06:22.560 --> 0:06:26.719 puts those two sets together and that creates this what 0:06:26.839 --> 0:06:30.000 appears to be a three dimensional image, which is pretty cool. 0:06:30.040 --> 0:06:33.160 You're you're tricking your brain into thinking that you're perceiving 0:06:33.200 --> 0:06:36.800 something that actually has depth as opposed to just heighten 0:06:36.880 --> 0:06:41.279 with right, groovy, right, Yes, you were looking at me 0:06:41.400 --> 0:06:43.680 like I wasn't sure whether you're gonna say something. Yeah. 0:06:44.200 --> 0:06:48.320 In our three D Cameras podcast, we talked about the 0:06:48.440 --> 0:06:53.560 ways in which you have to uh use technology to 0:06:54.200 --> 0:06:56.760 achieve this effect on the front end, you have to 0:06:56.839 --> 0:07:00.520 create the technology. And uh, in order to do that 0:07:00.600 --> 0:07:03.360 with with a movie or a TV show, Um, they 0:07:03.360 --> 0:07:07.520 will often use two cameras spaced with with lenses spaced 0:07:07.560 --> 0:07:10.600 about as far apart as your eyes, because they have 0:07:10.680 --> 0:07:13.880 to use these two different pictures and combine them in 0:07:13.920 --> 0:07:17.320 a way that will allow you to see them in 0:07:18.760 --> 0:07:21.400 phoe three D. Yeah, exactly, and in the way that 0:07:21.440 --> 0:07:24.920 your brain interprets as being three dimensions right now. Uh, 0:07:25.120 --> 0:07:28.320 the three DS has on its case on the outside 0:07:28.640 --> 0:07:31.280 two little cameras that are about that far apart, which 0:07:31.320 --> 0:07:34.280 aid and but that's not all of it. And I, 0:07:34.520 --> 0:07:37.880 you know, sort of sort of interrupted the glasses thing 0:07:38.120 --> 0:07:40.000 just because I wanted to give you an idea that yes, 0:07:40.040 --> 0:07:42.440 this this plays into the creation of the games because 0:07:42.440 --> 0:07:45.160 there have to be more than one image and there 0:07:45.160 --> 0:07:48.280 has to be some way to make it fool your 0:07:48.280 --> 0:07:53.600 brain into thinking, uh that it's that distance apart. And 0:07:53.640 --> 0:07:55.440 that's one of the ways in which they create the 0:07:55.480 --> 0:07:56.920 game in order to do that. But then you have 0:07:57.000 --> 0:08:00.680 to see it. Now for TV or a movie, Uh, 0:08:00.840 --> 0:08:03.840 we usually think about having to wear the glasses and 0:08:04.040 --> 0:08:06.120 a couple of different ways to actually more than a 0:08:06.120 --> 0:08:08.240 couple there three or four different ways, right, But but 0:08:08.360 --> 0:08:11.160 basically the basic way is that you overlay these two 0:08:11.240 --> 0:08:13.520 sets of images on top of one another, and then 0:08:13.560 --> 0:08:16.280 you find some way to filter them out. Filter one 0:08:16.280 --> 0:08:19.640 set of images out per eye now, might be through 0:08:19.680 --> 0:08:23.800 color or or polarity of the light. Um, there are 0:08:23.840 --> 0:08:27.360 a lot of different ways, but that that requires glasses. Now, 0:08:27.520 --> 0:08:29.840 glasses free. This is something that Chris Knight got to 0:08:29.840 --> 0:08:32.840 see in person. We actually took a field trip a 0:08:32.840 --> 0:08:35.839 couple of years ago out to a company that does 0:08:36.040 --> 0:08:41.960 glasses free lenticular displays, yes, which was interesting and also 0:08:42.040 --> 0:08:44.800 kind of disorienting. Yeah. Yeah, Plus I was a little 0:08:44.800 --> 0:08:46.880 worried because I had to forge my mom's signature on 0:08:46.920 --> 0:08:49.160 the permission slip from the field trip because he had 0:08:49.200 --> 0:08:52.600 been a bad boy up to that I was distracting 0:08:52.600 --> 0:08:56.560 others in class. But um, yeah, on on on a 0:08:56.600 --> 0:09:01.320 big screen TV. Uh, you can use lenticular displays to 0:09:01.840 --> 0:09:04.840 achieve the three D effect without having to wear glasses. Now, 0:09:05.040 --> 0:09:07.959 if you've ever had one of those little poster sorry 0:09:08.000 --> 0:09:12.520 postcards or uh, I remember actually when I had a 0:09:12.600 --> 0:09:14.760 drink that I got back in the days of atari 0:09:14.840 --> 0:09:18.480 pac Man For I actually have a pac Man sticker 0:09:18.880 --> 0:09:22.040 and it uses a lenticular film. Yeah, there's a lenticular 0:09:22.080 --> 0:09:25.199 film that goes over the the images because there's actually 0:09:25.240 --> 0:09:27.640 more than one image on that sticker, but but you 0:09:27.640 --> 0:09:31.360 can only see one image depending upon the angle you're 0:09:31.400 --> 0:09:34.560 looking from. Yeah, if you run your finger over it, 0:09:34.800 --> 0:09:37.240 or your finger nail even more specifically, it sounds like 0:09:38.000 --> 0:09:40.839 you're walking in corduroy pants, you get that. Yeah, there's 0:09:40.840 --> 0:09:42.839 a little you can feel the ridges. Yeah, yeah, I 0:09:42.840 --> 0:09:46.160 I used to have a postcard that was Luke Skywalker 0:09:46.160 --> 0:09:49.120 and Darth Vader having a lightsaber duel, and you know, 0:09:49.160 --> 0:09:51.680 you tilt the postcard back and forth and it would 0:09:51.720 --> 0:09:54.560 look like they were fighting. It was a very limited 0:09:54.600 --> 0:09:57.200 amount of animation. And the way that worked is that 0:09:57.559 --> 0:10:00.880 those that plastic film you can think of those is 0:10:00.880 --> 0:10:04.160 actually little tiny lenses that, when at a certain angle, 0:10:04.200 --> 0:10:07.360 allow you to view the image just from you know, 0:10:07.800 --> 0:10:10.040 you could just view one set of lines and all 0:10:10.040 --> 0:10:12.800 those lines together make up an image. But if you 0:10:12.880 --> 0:10:15.240 tilt it a little to the right or to the left, 0:10:15.520 --> 0:10:17.600 then you're looking at a different set of lenses, and 0:10:17.640 --> 0:10:20.520 those only let you see a different set of lines, 0:10:20.600 --> 0:10:23.240 And so you can put several different sets of lines 0:10:23.320 --> 0:10:26.360 all crammed together. These are basically bits of information, and 0:10:26.400 --> 0:10:30.040 then by tilting the postcard back and forth, you're seeing 0:10:30.320 --> 0:10:34.200 this these different images, whole images in sequence, and if 0:10:34.200 --> 0:10:38.280 you do it fast enough, it looks like it's animated. Yes, 0:10:38.440 --> 0:10:41.080 and I was thinking we probably should since I'm sure 0:10:41.080 --> 0:10:44.200 someone will want to know about that TV. The TV 0:10:44.360 --> 0:10:48.000 works on that biggest scale. The The only problem is 0:10:48.360 --> 0:10:50.120 there are these little it's it's kind of hard to 0:10:50.679 --> 0:10:55.400 explain in non three D, but they're little areas. If 0:10:55.400 --> 0:10:57.480 you've ever been in a perfect stereo set up where 0:10:57.480 --> 0:10:59.800 you're in the right exact space and you can totally 0:10:59.840 --> 0:11:02.200 make out the left and the right channel, but if 0:11:02.240 --> 0:11:03.560 you move a little to the left of the right, 0:11:03.720 --> 0:11:06.280 or forward or backward, all of a sudden, you lose 0:11:06.360 --> 0:11:09.200 that true stereo effect. It's it's like that for the 0:11:09.200 --> 0:11:12.720 t vs, because if you step just hair at a place, 0:11:12.760 --> 0:11:15.120 all of a sudden, the image gets distorted a little 0:11:15.160 --> 0:11:16.920 bit and you can't see it in three D anymore. 0:11:18.200 --> 0:11:20.800 Dead spots, Yeah, which is why you don't see that 0:11:20.880 --> 0:11:23.560 on every three D TV. Right. The way I I 0:11:23.600 --> 0:11:26.800 describe it usually is imagined that the television, or in 0:11:26.840 --> 0:11:28.960 this case, the three D S is in the center 0:11:29.040 --> 0:11:32.640 of a pie. I'll see you had to bring pie 0:11:32.679 --> 0:11:34.600 into it. Now I'm gonna be thinking about that. And 0:11:34.600 --> 0:11:37.439 and now a pie that's been sliced, right, so you've 0:11:37.480 --> 0:11:39.680 got the three D s's at the center of the pie. 0:11:39.720 --> 0:11:42.760 So you've got these slices that that converge at the 0:11:42.760 --> 0:11:46.600 three D S. If you happen to be positioned in 0:11:46.640 --> 0:11:49.600 the middle of a slice of pie, then you get 0:11:49.640 --> 0:11:52.480 the three D experience. But if you are bestride two 0:11:52.480 --> 0:11:57.960 slices of pie, if that slices in between betwixt thy feet, 0:11:58.840 --> 0:12:01.079 then then you've got to end up with this weird, 0:12:01.200 --> 0:12:04.320 muddled image. And it's gonna not it's gonna look really 0:12:04.400 --> 0:12:06.360 kind of cloudy. Your brain is not really gonna know 0:12:06.400 --> 0:12:08.760 what to do with it, and uh, and it really 0:12:08.800 --> 0:12:11.559 is disorienting. I can tell you from experience, because one 0:12:11.600 --> 0:12:13.079 of the things we found out while playing with the 0:12:13.160 --> 0:12:17.600 Nintendo three DS is it's a little disorienting. Disorienting when 0:12:17.640 --> 0:12:20.760 you're playing it yourself, but even more so if you 0:12:20.800 --> 0:12:23.520 try to watch someone else play, because you are going 0:12:23.559 --> 0:12:26.120 to be looking over that person's shoulder and you're not 0:12:26.160 --> 0:12:28.760 going to be in that sweet spot. Now That's one 0:12:28.800 --> 0:12:31.160 of the reasons why that three DS was considered to 0:12:31.160 --> 0:12:34.480 be viable was because if you're playing a handheld device, 0:12:34.679 --> 0:12:37.240 generally you're holding it in front of yourself and you're 0:12:37.240 --> 0:12:40.160 holding it about the right distance away for that three 0:12:40.280 --> 0:12:43.200 D to work right, You're you're holding it around, you know, 0:12:43.720 --> 0:12:46.439 fourteen to eighteen inches away from your face. You're holding 0:12:46.440 --> 0:12:48.800 it in front of you more more likely than not, 0:12:49.400 --> 0:12:52.120 and so it's kind of a controlled environment. Whereas if 0:12:52.120 --> 0:12:54.840 you were to put this in, say a television, well 0:12:54.880 --> 0:12:57.520 then you have to arrange your entire living room so 0:12:57.559 --> 0:13:00.160 that you are always seated in one of those sweet 0:13:00.160 --> 0:13:02.040 spots to get the three D or else you'll just 0:13:02.080 --> 0:13:04.319 get a massive headache. So if you were to sit 0:13:04.360 --> 0:13:06.320 a little to the left on the couch, suddenly you 0:13:06.320 --> 0:13:08.360 can't see the three D image anymore, and and it's 0:13:08.360 --> 0:13:11.880 just a jumbled mess onto television. So the three D 0:13:12.040 --> 0:13:14.440 S the idea was that the form factor suited that 0:13:14.559 --> 0:13:19.280 three D technology. Now you were talking about how you 0:13:19.320 --> 0:13:22.200 have to have two different sets of images, it's it's 0:13:22.320 --> 0:13:24.560 and that's true with these three D games if you 0:13:24.640 --> 0:13:26.400 have it on three D mode. And the nice thing 0:13:26.440 --> 0:13:28.200 about the three D S so you can turn the 0:13:28.200 --> 0:13:30.120 three D mode off if you If you slay the 0:13:30.160 --> 0:13:32.200 three D switch all the way down, it goes to 0:13:32.280 --> 0:13:34.800 two D mode and you only have a single set 0:13:34.840 --> 0:13:37.800 of images if you because you have to have two 0:13:37.800 --> 0:13:39.600 sets of images. That means that you have to have 0:13:39.679 --> 0:13:44.240 custom games for this device. Right. You can't suddenly start 0:13:44.280 --> 0:13:47.880 playing all your old Nintendo DS games in three D 0:13:48.120 --> 0:13:50.760 right then, Now it is compatible with those old games, 0:13:50.760 --> 0:13:52.079 but you are not going to get the three D 0:13:52.160 --> 0:13:54.640 effect because those old games were not designed with two 0:13:54.679 --> 0:13:58.040 sets of images exactly. Another thing I should point out 0:13:58.120 --> 0:14:01.160 is that if you have any problems with your site 0:14:01.240 --> 0:14:04.240 in one eye, like let's say that you you're blind 0:14:04.240 --> 0:14:07.200 in one eye, or you just have a medical condition 0:14:07.480 --> 0:14:09.840 um that that messes with your vision in one eye, 0:14:10.200 --> 0:14:12.200 you may not be able to see three D through 0:14:12.240 --> 0:14:16.520 parallax views the way that a person with good vision 0:14:16.520 --> 0:14:20.720 in both eyes could. Right. Because of that, Nintendo kind 0:14:20.760 --> 0:14:23.440 of is kind of shying away from making three D 0:14:23.600 --> 0:14:27.960 an integral necessary part of games on the three D S. 0:14:28.360 --> 0:14:31.440 In other words, you can buy three D games for 0:14:31.520 --> 0:14:34.000 the three D S, but there won't be any games 0:14:34.000 --> 0:14:37.040 in which the three D component is necessary for you 0:14:37.080 --> 0:14:39.640 to be able to play that game. Now, that goes 0:14:39.800 --> 0:14:42.440 against the Mario game that I saw when I was 0:14:42.480 --> 0:14:44.280 at E three, Because the Mario game I saw, if 0:14:44.320 --> 0:14:47.520 you turned the three D setting off, you suddenly could 0:14:47.560 --> 0:14:50.120 not see the platforms that you had to jump on 0:14:50.240 --> 0:14:52.880 as you were running through the levels. You can only 0:14:52.920 --> 0:14:54.880 see them in the three D mode. So that meant 0:14:54.960 --> 0:14:57.360 that the three D was necessary for you to be 0:14:57.400 --> 0:15:01.000 able to play effectively. Uh. Well, now on Nintendo saying well, 0:15:01.000 --> 0:15:02.680 that may not be the best idea because there are 0:15:02.680 --> 0:15:05.760 some people who just can't enjoy games. Uh and so 0:15:06.120 --> 0:15:08.200 if it's in just three D mode, so we don't 0:15:08.240 --> 0:15:11.160 want to, we don't want to you know, discount them. 0:15:11.280 --> 0:15:12.840 We don't want to leave them out of the fun. 0:15:13.560 --> 0:15:15.840 So three D should just be kind of a feature. 0:15:16.000 --> 0:15:19.280 It's at that point one could argue, and I have 0:15:19.480 --> 0:15:22.400 made this argument, the three D feature on the three 0:15:22.480 --> 0:15:25.120 D s becomes more of a gimmick than a feature 0:15:25.280 --> 0:15:28.280 because it's not necessary to the game. It's not like 0:15:28.320 --> 0:15:32.600 the WE games where the WE remote is integrated part 0:15:32.680 --> 0:15:36.520 of gameplay, right, I mean with those games, like the 0:15:36.840 --> 0:15:39.640 games that use the WE remote or the the the 0:15:39.680 --> 0:15:43.480 WE fit board, those things, you know, that's part of 0:15:43.480 --> 0:15:46.560 the gameplay. If if there's not a simple way where 0:15:46.560 --> 0:15:48.520 you just switch that out and use a regular controller, 0:15:49.560 --> 0:15:52.320 that that's more of a game that was where it's 0:15:52.320 --> 0:15:55.480 integrated with the whole system, right Like for example, the 0:15:55.680 --> 0:15:58.960 Mario Kart WE has the WE steering wheel, but the 0:15:59.000 --> 0:16:01.720 WE stealing steering is essentially an inert piece of plastic 0:16:01.960 --> 0:16:06.000 in which you snap the uh WE remote, So you 0:16:06.040 --> 0:16:09.160 don't need the steering wheel to play that game. You 0:16:09.240 --> 0:16:13.680 just hold the WE remote sideways and you know, make 0:16:13.760 --> 0:16:16.960 room room sounds. You can argue, Yeah, you could argue 0:16:16.960 --> 0:16:19.600 that that that steering wheel is more or less a gimmick, 0:16:19.920 --> 0:16:21.880 although I would assume it would make it a little 0:16:21.880 --> 0:16:25.320 easier to hold and manipulate the WE remote in that case. 0:16:25.800 --> 0:16:27.640 But you don't need the little tennis racket thing either 0:16:27.680 --> 0:16:30.160 to play exactly yeah, or like one that shaped like 0:16:30.160 --> 0:16:32.240 a wand to play a Harry Potter game or something 0:16:32.280 --> 0:16:35.160 along those lines. Yeah, So it feels almost more like that, 0:16:35.200 --> 0:16:39.680 like one of the kind of superfluous WE accessories. That's 0:16:39.720 --> 0:16:41.640 kind of how the three D feature on the three 0:16:41.720 --> 0:16:45.080 D S feels. If you remove the three D as 0:16:45.120 --> 0:16:47.360 an integrated part of the game, but let's talk a 0:16:47.360 --> 0:16:50.640 little bit about you know, we we mentioned lenticular displays. 0:16:51.400 --> 0:16:54.160 The way Nintendo actually implements this technology is what we 0:16:54.240 --> 0:16:57.160 call the parallax barrier, and a parallax barrier is kind 0:16:57.160 --> 0:17:01.560 of neat. Yes, okay, So the screen that you're looking at, 0:17:01.560 --> 0:17:03.480 the three D screen, is an l c D screen. 0:17:03.960 --> 0:17:06.359 On top of that screen is a second l c 0:17:06.520 --> 0:17:10.040 D screen that uses these little liquid crystals to create 0:17:10.760 --> 0:17:14.679 kind of like shutters, and the shutters block off the 0:17:14.720 --> 0:17:19.080 way light bounces or projects off of the back lit 0:17:19.760 --> 0:17:23.560 uh three D screen, And by shuttering off the light 0:17:23.680 --> 0:17:28.439 just right, it directs light in two particular directions, the 0:17:28.520 --> 0:17:31.119 left eye and the right eye. So it's blocking the 0:17:31.200 --> 0:17:33.159 right eye's image to the left eye and it's blocking 0:17:33.200 --> 0:17:37.440 the left eye's image to the right eye. Now, if you, uh, 0:17:37.600 --> 0:17:42.040 if you haven't been following us on Facebook, and if not, 0:17:42.200 --> 0:17:46.919 why haven't you? Um, you probably are unaware of what 0:17:46.960 --> 0:17:49.040 we are about to get into. Actually, I was going 0:17:49.080 --> 0:17:51.800 to bring up next, which is that when I wasn't 0:17:51.920 --> 0:17:54.760 here one day, they took it upon themselves to tear 0:17:54.840 --> 0:17:57.080 this thing apart. If you want, I'll give it to you. 0:17:57.119 --> 0:18:00.640 It's in a bag. Thanks. Most bits in a bag. 0:18:00.880 --> 0:18:03.080 We can eBay that the chunks of it. I had 0:18:03.080 --> 0:18:06.640 to throw away some of the pieces they were Yeah. So, 0:18:06.640 --> 0:18:09.560 so could you actually pull these screens apart? Can you 0:18:09.600 --> 0:18:15.359 actually see this for yourself? Well, because it's liquid crystal display, No, 0:18:15.440 --> 0:18:17.560 you're not gonna I mean, I wouldn't recommend it. Um, 0:18:17.560 --> 0:18:19.280 first of all, you can avoid your warranty, and second 0:18:19.320 --> 0:18:22.600 of all, you're gonna break your three D s Uh. 0:18:22.880 --> 0:18:25.920 If I had a heat gun, I could have weakened 0:18:25.960 --> 0:18:29.159 the adhesive enough to pull apart the screens. But I 0:18:29.200 --> 0:18:31.639 didn't have a heat gun, so I didn't bother to 0:18:31.720 --> 0:18:34.920 try and force that. UM. I took the I took 0:18:34.960 --> 0:18:37.520 the protective covering off of the three D screen so 0:18:37.560 --> 0:18:39.760 that you could see where the speakers are mounted. The 0:18:39.760 --> 0:18:42.199 speakers are mounted on the three D screen, not on 0:18:42.240 --> 0:18:45.679 the base. UM you can see where the forward facing 0:18:45.720 --> 0:18:48.920 camera was. Uh, that kind of stuff. But you could not. 0:18:49.320 --> 0:18:53.879 I couldn't pull out the screen and then uh split 0:18:53.960 --> 0:18:58.120 in twain, but uh, yeah it was. It's It's interesting 0:18:58.119 --> 0:19:00.840 that the little UM three D switch on the left 0:19:00.880 --> 0:19:04.200 on the right rather of the screen, if you put 0:19:04.240 --> 0:19:06.200 it all the way down, it turns the three d off. Well, 0:19:06.240 --> 0:19:08.480 if you start sliding it up, it actually adjusts the 0:19:08.600 --> 0:19:10.080 three D and the way it adjust the three D 0:19:10.200 --> 0:19:14.080 is the width of the little crystal shutters. By by 0:19:14.080 --> 0:19:16.359 sliding it up, it adjusts the width so that you 0:19:16.480 --> 0:19:19.680 get more or less light coming to you from the 0:19:19.800 --> 0:19:24.080 various screens, and it will actually offset the pictures a 0:19:24.119 --> 0:19:27.280 little bit more too, which means that you can adjust 0:19:27.280 --> 0:19:31.120 the depth of field. And the reason for that is that, 0:19:31.720 --> 0:19:35.240 you know, we were talking about how these displays kind 0:19:35.240 --> 0:19:40.400 of mimic how our eyes are are spaced on our heads. Well, 0:19:40.440 --> 0:19:43.560 most of the time, you have to estimate that, right, Sure, 0:19:43.960 --> 0:19:45.960 you base it on an average, so you see, the 0:19:45.960 --> 0:19:49.639 average person's eyes are so so many centimeters apart, and 0:19:50.080 --> 0:19:52.880 if your device doesn't have any way of adjusting for that, 0:19:52.920 --> 0:19:54.399 you just have to go for the average. And you 0:19:54.440 --> 0:19:57.560 realize that any individual person who views that is going 0:19:57.640 --> 0:20:01.200 to have a variable experience based upon how far apart 0:20:01.359 --> 0:20:04.960 their actual eyes are. So let's say that the average 0:20:05.000 --> 0:20:07.520 is a certain amount, and that my eyes happened to 0:20:07.560 --> 0:20:10.199 be a little closer together than average. That means that 0:20:10.240 --> 0:20:14.320 if I'm looking at a fixed parallax display, like there's 0:20:14.320 --> 0:20:17.000 no way to adjust that three D I'm not going 0:20:17.040 --> 0:20:19.440 to get as good an experience as someone who whose 0:20:19.440 --> 0:20:22.520 eyes are closer to the average. Well, this, this little 0:20:22.560 --> 0:20:25.640 switch allows you to change the offset of those images 0:20:25.720 --> 0:20:28.720 and the width of those uh those crystals to be 0:20:28.800 --> 0:20:32.080 able to uh to get it closer to what your 0:20:33.280 --> 0:20:38.080 your your physiological makeup is, so you can get as 0:20:38.160 --> 0:20:41.240 close to an ideal experience as possible. All that being said, 0:20:41.560 --> 0:20:43.760 after about ten minutes of playing with this on three 0:20:43.840 --> 0:20:47.040 D mode, I started to feel a little uh se sick, 0:20:48.280 --> 0:20:50.600 which is weird because I don't get motion sickness easily. 0:20:51.000 --> 0:20:53.719 I'm like a roller coaster fanatic, and I ride like 0:20:53.800 --> 0:20:56.280
