How the Nintendo 3DS Might Handle 3D Display

CmdrTaco posted about 4 years ago | from the i-can-see-my-hand dept.

Displays 77

itwbennett writes "Blogger Peter Smith weighs in with some possibilities for how the new Nintendo 3DS handheld gaming system will provide 3D gaming without the need for 3D glasses. The DSi has cameras, which means the 3DS will have to have them too if it's going to be backwards compatible. We've also heard rumors that the 'next DS' will have tilt-sensors better than the iPhone. With either the camera or tilt-sensors either of these 'faux 3D' systems would work. But since we've seen the DSi do this already, it doesn't seem likely that the new hardware will rely on the same old trick. Enter our friends at Engadget, who uncovered some details from Japanese newspapers. If they're right, the Nintendo 3DS will incorporate parallax barrier LCD screens from Sharp (see also this explanation of dynamic parallax barrier screens). This is the same technology used in a few '3D Laptops.'"

Nintendo was able to secure free WiFi for a lot of major network operators in Europe.
If they include a tranceiver for downloading games then using the built in microphone to make phone calls should be trivial.

Wow, that's just a big bag of crazy.

How does a mobile gaming device threaten the general purpose computer? I'd say it actually strengthens it.

As far as locked down devices go, phones have always been fairly locked down, same as PDAs, gaming consoles, etc. I can't say I've seen an open source gaming console take off. This is not to say I'm against open source, far from it, but you have to give respect where respect is due.

I really can't understand this luddite attitude that seems to rule on a tech site. "This will destroy x" is almost the catch cry of some posters here. It's actually very sad.

I'm not saying to blindly embrace technology, at the same time, blindly rejecting new technologies is worse.

Re:This is why I love competition (1)

LordSnooty (853791) | about 4 years ago | (#31623982)

These devices will only become more powerful and popular, so web sites and app coders will converge to that segment, making them more appealing to the everyday consumer (who to be fair has probably had their fill of malware on the general-purpose platform) - there's a real danger that the market for the general-purpose computer upon which one can run programs that aren't necessarily approved by the device's masters will contract to a level that makes it uneconomic.

Not full/real 3D (1, Interesting)

morphles (1257124) | about 4 years ago | (#31612962)

Yesterday i was checking anaglyph rendering capability of game i'm playing and then it hit me. Nether anaglyph nor interlaced glasses and probably not even VR glasses are full true 3d. Here is why:
glasses give you perception of depth that is very cool effect and all, but one thing is missing: you move your head you see different stuff. Now head tracking gives joust that and it is also very cool in itself. Now what i would really like to try is some glasses 3d (preferably non anaglyph, cause anaglyph is hard on eyes) + head tracking 3d (probably can be done much easier tracking glasses) to get real true 3d experience :) Well this rant is just to point out that there seems to be no real/true 3d yet unless you clobber something like this yourself using graphics card anaglyph render and some hacked up head tracking. Well one more point that such true 3d would be quite difficult to do for non interactive/non rendered graphics i.e. movies. But some day maybe :)

Re:Not full/real 3D (1)

gaggle (206502) | about 4 years ago | (#31613630)

Indeed, your point is valid. It's a classic issue that we don't get perspective-changing 3d with the current round of 3d. The equally-classic response to your idea of "proper 3d" is that it causes problems for multiple viewers since you suddenly can't sit at an angle to the TV because it leaves you looking at the walls of the recording studio.

How would you choose to solve it? I don't mean technically, let's just imagine it's possible in an easy and nonintrusive way, how do you then imagine the livingroom and/or theater of the future?

Re:Not full/real 3D (1)

morphles (1257124) | about 4 years ago | (#31614550)

Hm yeah quite an interesting problem. You stand by the side of tv and you side of scene (if your watching concert). Well maybe you could do something as nonlinear video angle change. Like when you are moving closer and closer to the edge angle change on video/picture gets smaller and smaller. So this way you could still see stuff from different angles adn get impressive viewing angle change while sidestepping at center of screen, but still not see sides of scenes/studios/whatever when sitting at the side of screen/tv.

And yeah multiview + head tracking is probably hardly possible, but sill some day id really like to try some game with some glasses (probably anaglyph because its way way cheaper) and some head tracking, should be very impressive :)

Re:Not full/real 3D (1)

KDR_11k (778916) | about 4 years ago | (#31613744)

Nintendo released a game using the DSi camera for head tracking recently (it's only available in Japan) so you can expect this thing to do head tracking.

Re:Not full/real 3D (0)

Anonymous Coward | about 4 years ago | (#31614378)

It should be called "stereo vision". In addition to what you pointed out, the focus, or depth of field is also generally fixed (in games traditionally there isn't this limitation though) so your eyes can't focus on things in the background for instance.

Depth of field (0)

Anonymous Coward | about 4 years ago | (#31614526)

Head tracking wouldn't do it.
If you want a true 3D illusion, you need eye tracking and something to determine what the eye is actually focusing on.
Right now when you're looking at a "3D" picture, only certain things will be in focus, everything else will be blurry, no matter how much you focus on them.
Head tracking will do nothing for that.

Re:Depth of field (1)

LordVader717 (888547) | about 4 years ago | (#31627578)

That would require a complete photon vector field, and seems inconceivable. Certainly for something as portable as a handheld.

Re:Not full/real 3D (1)

fastest fascist (1086001) | about 4 years ago | (#31615022)

I wonder... It doesn't make much sense to me to employ any kind of stereoscopic or similar display method on a device so small. Not only does the size of the screen mean any 3d effect achieved will be quite subdued, and I guess you'll end up calculating each frame twice (or three times for the triple-veil display?). Maybe the horizontal resolution for each angle is one third of the actual display resolution (don't know, don't care to look it up right now), but if so, that too seems like a picture quality compromise more than a plus. Now, head-tracking, on the other hand, would seem ideal for a small device. Since the screen is small, you wouldn't need to move your head much in relation to it to get a significantly different view. This would probably enable interesting gameplay mechanics as well beyond just a feeling of depth.

Saying "No" to 3D for now (1)

Goffee71 (628501) | about 4 years ago | (#31613050)

I understand why 3D television is the current fad. Since a decent number movies are now being made in 3D, there is some logic in a range of big-screen TVs for those into their audio-visual experiences. But, for the rest of us? Either you'll have recently upgraded to HDTV and one of the appropriate services (cable, Sky+HD, Freesat, whatever) and be wondering what the fuss was about, or you've up-upgraded one of those services, or your TV.
Similarly with gaming, good on Nintendo for trying something different (ignoring its previous attempt with Virtual Boy [a good title if ever there was one for one of those 3D porn movies]) but 3D in such a small space seems counter-intuitive and even if it works well, I worry about how still you'll have to sit to get the full effect for extended periods. I can see the warning on games for that system saying "take a break every 10 minutes, for at least 30 minutes" - kind of breaking the fun part.
So, give it a few years - when the content is properly there and its more than just crappy Doctor Who trailers that look rubbish in 2D (ie how 90% of the world saw it), and the prices have dropped from bloody stupid to ouch, but I'll do it! Full rant from yesterday; http://bit.ly/9BKiRG [bit.ly]

Re:Saying "No" to 3D for now (0)

Anonymous Coward | about 4 years ago | (#31613972)

Untrue, I still have a 34" SD flat-panel with digital tuner, I just plugged the antenna that came on the house to the TV, works good enough. I get the wide-screen effect of HD, but none of that other stuff. Call me a late adopter, but I'd still buy CRTs if they were reasonably cheep and thin, I liked not having to worry about my toddler breaking the screen.

The thing I find hilarious is the way so many things over the airwaves are made into this hybrid wide-screen/narrow-screen version where you'll see all these things that belong on the edge sitting more in the middle of the TV. (eg. during football games they had a ticker terminating in an ad, the ad had to be placed so that narrow-screen wouldn't miss it, but this resulted in the ticker terminating about 80% of the way across the screen, looked terrible.)

types of 3d (4, Informative)

goombah99 (560566) | about 4 years ago | (#31613078)

While 3D seems like a simple enough concept, faking 3D on a screen can go several different routes.

the kind you have in theaters or with shutter glasses approximates supplying each eye with a different image just like it would in real life. So what's the catch? well you get the same two images no matter where you sit in the theater. So 1) it can't be perfectly correct for every point of view in the theater 2) you don't see the expected change if you move. that is if you move you'd expect to be able to see around one object blocking your view of another. but that does not happen with this kind of 3D.

then there are ones that try to broadcast a different image at every different angle. You can't really do that in practice so you broadcast one or two images at a couple angles and let interpolation happen.

lenticular lenses and these blocked screen do this second type.

this recovers the head-motion 3d but has the drawback of having less of a sweet spot where each eye gets the perfectly registered image. However even when this fails, it can fall back to monocular 3D where at least the view point is right.

this kind of 3d is better for up close viewing by a single person. that is, for a hand controller.

A final kind of 3D is monocular 3D. there there is one image but you eye track or tilt track in a way that lets you update the image for the new point of view.

...but I'm more interested in:

Screens that are more resistant to scratches, hinge mechanisms that don't get all loose and weird, higher resolution displays, better sound (with headphones the DS actually puts out decent sound, but the internal speakers are worthless), and larger ad-hoc wifi range.

The DS is a fantastic piece of hardware, don't get me wrong...but those are the improvements I would like to see the most, ESPECIALLY the larger ad-hoc range. When a bunch of friends and I are playing Civ Rev and I have to go to the bathroom, or one of them decides to dip out for a quick cig, it would be nice to be able to keep the wireless connected.

Now that there are a lot of 3D solutions for PCs that actually work, I'd love to see a new version of Descent. [wikipedia.org]

I have NO interest in 3D television. I've seen it back when Pepsi did that 3D superbowl commercial - it was the only superbowl I ever watched and it was to see the 3D advert, and it's nice and all, but I don't want 3D television. Why? If it introduces ANY flicker, I am not interested. If it tempts directors to have things move toward the camera just for the 3D effect, like most 3D movies, it will degrade the quality of productions. Thanks, but no thanks.

What I care about in a television is 120Hz (I see the "stop motion" effect on the big screen throughout the films and I find it really distracting and the 120Hz eliminates that distraction), good black levels and great contrast ratios, and of course, halfway decent sound. Internet "widgets" are a plus, as is online firmware updates, but not a requirement (I rarely ever use the widgets on my Samsung LN46B650 because most of the widgets are so horrible). Widgets for Hulu, Crackle, and most importantly Netflix would be a big WIN.

But 3D? I won't say no one needs it, because I'd be like the open source zealots who try to use Linux for every single client, but I will say that I think it will cause directors to focus (no pun intended) more on using cliche 3D gags than they will on the quality of the dialog.

TheSync (5291) | about 4 years ago | (#31613772)

Here is a rumor that the 3DS will use the 3M film 3D LCD screen [i4u.com].

The screen is a frame-sequential two-view autostereoscopic system based on directional backlight. The left eye frame is displayed with the backlight applied on one side of the 3M film that directs the light into your left eye, the right eye frame is then displayed with the backlight applied to the other side of the 3M file to direct the light into your right eye.

I have one on the viewfinder of my Fuji FinePix Real 3D [fujifilm.com] stereoscopic digital camera, and it works pretty well. You do have to position yourself fairly precisely in front of the screen to get the stereoscopic effect, but that is not too hard with a portable device.

The Virtual Boy, Nintendo's first attempt at a 3D video game system, was an utter failure; I bought mine a year after its release for 30 dollars, marked down from 200.

I actually kind of liked playing games in 3D, it really does change the experience. But the system game me pretty severe headaches after an hour of playing. I'd like to see how they can avoid that this time around.

I do in fact remember Virtual Boy. From an engineering standpoint, it's actually quite fascinating. They're using a single row of red LEDs and a set of mirrors to create the image. It's almost like DLP.

This IS real 3D (1)

gurps_npc (621217) | about 4 years ago | (#31614426)

I hate the fact that some people are confusing holographs with 3D.

3D means you can view more than 2 dimensions. As humans have only 2 eyes, and we get the real life 3d effect from using both eyes, if you provide different information to each eye, you get 3D that is as "real" as anything in real life. It provides specific detailed information about which item is 'in front' of and 'behind' each item, unlike a photograph where you can do silly tricks like make it look like you are pushing the leaning Tower of Pisa over. With these 3D screens, such cheap special effects no longer work.

Holograms however are MORE than 3D. Witha Hologram you can get up and move your HEAD to get something that is beyond simply 3D, but is instead something I would call "immersive".

Asking for immersive 3D and calling regular 3d fake is like saying those photographs you have are not really 2D because they don't move. Bullcrap. The immersion stuff is far beyond 3D and people should stop trying to claim that 3d = immersive Holograms

The problem is, there is no hard line between different levels of immersive. They go from merely being able to move your head to get a different view, to being able to walk around or even THROUGH an object, similar to a star trek Holo-deck.

But that is way way beyond what any normal person calls 3D. Stereoscopic vision, as per lenticular or this "parrallax" viewing counts as REAL 3D. The information is just as much as you get in real life using both eyes.

The definitons aren't defined properly. Our perception of depth is based on stereo vision, you stereoscopic images are a pretty perfect representation, at least for a fixed view.

For a perfect representation from every view you of course need to recreate the complete vector field of photons, which is pretty inconceivable.

A lot of people like to talk about two technologies: Hologrophy and Volumetric displays.

But Hologrophy is also incomplete: It completely lacks perspective. Holograms are made at one viewing distance. But if you move away from the hologram the perspective doesn't change. Foreground objects have the same proportions to background objects as seen when close up.

While volumetric displays can show perspective, it's a completely inadequate experience for movies and most games. It would be like watching toys battle it out on your desk. No need for surround sound, that's for sure.
Although it would be cool for strategy games and visualisation.
But that's even assuming it's physically possible. Nobody has figured out how to create and opaque image in thin air. (thin air is indeed necessary, you don't want the index of your medium distorting your image)

Face Tracking not necessary (2, Interesting)

jeffeb3 (1036434) | about 4 years ago | (#31614492)

We are talking about a low powered, portable toy. Face tracking isn't likely to be part of the trick.
1) There's not enough processing to track the face. You could make it work, but I personally don't feel that it fits in with the pattern Nintendo's previous elegant design solutions.
2) The user will naturally keep their face in the 3D focus sweet spot. An HDTV is hard because people are spread across the room. But for Nintendo, the user is always in front of the screen, and they are always within arms reach.
3) You can use the inertial sensors to change the angle of the sweet spot. People are going to want to see around obstacles (and the game makers want to let them). But you can train users to keep their head in one spot, and roll the DS to see around obstacles. With that Parallax screen, you can adjust the sweet spot based on the amount of tilt of the DS.

Truth be told, dynamic parallax barrier screens aren't even necessary, for precisely the reasons you outlined. They're useful for displaying different pairs of 3D images to two different viewpoints, in effect having more than one simultaneous sweetspot, and they're useful for head-tracked systems that allow large motions by "steering" the sweetspot to follow the viewer. There's no need for any of that in a handheld. A completely static barrier, like the original Varrier, works just fine.

That solution sounds far more likely, given Nintendo's current habit of "good enough." The Wii hardware specification compared to the PS3 should be plenty of indication of that. Dynamic parallax barriers require two LCD panels laid over the top of one another, which requires double the control circuitry, a brighter backlight, and of course, two panels in one, a significant added expense. Definitely not Nintendo's style.

On the other hand, it's right up Sony's alley. The next PSP just might have a dynamic parallax screen, if they think Nintendo is getting traction with a static barrier.

what, you consider the abomination that is Wii to be "elegant"?
you consider the DS to be "elegant"?

Nintendo may be good at making toys, but they can't design for shit.

They already have a DSi game with face tracking http://www.nintendo.co.jp/ds/dsiware/krgj/index.html.

Wow, that DS looks NOTHING like a GBA... (1)

filesiteguy (695431) | about 4 years ago | (#31615020)

The story had a related article from earlier. In it, they posted a picture of a GBA next to the DS article...

I'd much prefer no parallax filter and a camera-based head tracker.

pCubee 3D Cube Display for Nintendo 3DS in 2020 (2, Interesting)

i4u (234028) | about 4 years ago | (#31615412)

Researchers at the University of British Columbia have developed a cool 3D display dubbed pCubee. Imagine the Nintendo 3DS be like this interactive cube, Sony would start taking the 3DS seriously.
Users playing with pCubee experience new interaction techniques for 3D scene manipulation in a cubic display.
Watch the awesome demo video here [i4u.com].

Portrait view (1)

The_Marone (610210) | about 4 years ago | (#31616452)

I assume that any of these 3D screen technologies are unable to switch from landscape to portrait without losing either the 3D effect or the picture altogether. That is assuming also that the 3DS will have two unique screens. This may hurt the DS/DSi backwards compatibily aspect. It could also be a single screen device where the screen would be virtually split in two and rotated to portrait for DS/DSi games.
