Question Why have television manufacturers still not adopted the Nintendo 3DS's tech yet?

I don't understand it. This device has been available for almost four years now, and it seems to be the perfect glasses-free 3D technology... yet no display manufacturer other than Nintendo seems to have adopted it. Why are all the TV manufacturers still using glasses solutions? This is why 3D has never caught on. If they copied the 3DS's technology years ago, 3D would be big today.

With the New Nintendo 3DS, viewing angles are no longer a problem, as Nintendo has introduced a new innovation: the camera on the unit tracks your head's position and compensates for what angle you are viewing at.

It seems like this would be the perfect technology to implement in 2015 model 4K TVs. They could stick a small camera at the top of the TV like the New Nintendo 3DS has at the top of its 3D display to track the viewer's position.

I feel like this great technology for glasses-free 3D is already here and it is just being completely wasted on a crappy handheld system with a horrifying low-resolution screen. I think people would be blown away to see the 3DS's technology applied to a 4K TV.

It's nice to want things, but it's naive to presume that the tech can be simply blown up in size and magically work with 5+ people watching, and that display researchers are just sitting around twiddling their thumbs.

Because it happens to work only with a "crappy handheld system with a horrifying low-resolution screen". And it is already obsolete.

Check the Ultra-D thread and background info. The tech is beyond the eye-tracking adaptive parallax barrier.

One upcoming solution is called Ultra D and that is still awhile away yet and not perfect. Big difference from what will work on a handheld, low rez screen like you mentioned and something 1080p with multiple viewers. How is that camera going to work with a family of 5 or 7?

I didn't realize manufacturers could just copy patented tech. Why are TV manufacturers still using glasses? Because it's the only solution right now to deliver the most comfortable and most impressive 3D viewing experience. It's unlikely glasses free 3D will rival glasses on for many years to come.

This line intentionally left blank.

I am a pretty hard core gamer... I have a 3DS as well as Vita. The 3DS 3-d works ok if you hold the device so it does not move and play your game but, once you get off access, it does not work that well. I have had my device for many months and want to use the 3D on it but, gave up and mostly disable it.


I move the controller a lot (just a little) when I play a game on it and I find it worthless(in fact after playing for a 1/2 hour or so, it will give me a headache).


Just think about a big screen TV with this tech, I think it would be more problems than you think. Not everyone sits dead on and not everyone stays still for an entire 2 hour movie.

I don't care about multiple people; I'm a foreveralone and I'm the only one who ever watches my TV. There's never multiple people who need to watch my screen. And I'm not the only one. There are literally millions of us. We're a big market. And we're exactly the kind of people who like to piss away tons of money on the latest tech toys in order to distract us from our depression over not being able to find a mate.

Seems like this technology would be just fine for solo viewers. You'd think there'd be a place in the market for at least one model of TV using this technology. I guarantee you it would be especially popular in Japan among the NEET population. Glasses-free 3D waifus would be hugely popular.

That's funny, because I already addressed this. Nintendo has solved that problem with the New 3DS model released in Japan and Australia last month. A camera tracks your eyes and seamlessly adjusts the screen to compensate for you viewing off angle. The New 3DS's 3D tech is near perfect now.

You clearly haven't tried the New 3DS model yet. That's understandable, you're probably not Japanese or Australian. But I have a unit I imported and I can tell you it is a big improvement over the original model. This parallax 3D and camera eye tracking to compensate that Nintendo is using now is impressive stuff. The biggest tragedy is that it is paired with a low resolution handheld screen instead of a high resolution TV screen.

And the 3DS is unplayable with the 3D effect disabled. How do you guys stand that? It looks like hot garbage with the 3D disabled, because it cuts the screen's already pitifully low resolution in half.

More importantly, I'd like to know why Walmart hasn't stocked my hover board yet on shelves. Or is that in a few weeks, when it's 2015?"

Given that 3D hasn't really caught on, it's amazing we have as much available right now as we do.

Compared to Ultra-D the 3DS glasses free is ultra lame. The viewing angles are poor on the 3DS and if you get out of the sweet spot the image goes all wonky. Yes, I too thought the 3DS was wonderful and what could Ultra D do, but no, Ultra D is so much better - besides a huge 120 degree viewing angle, Ultra D degrades into plain old 2D when you've exceeded the angle and looks completely normal.

Yes the new 3DS is supposed to be better but still, I don't think it measures up. Maybe for one person, but that's not a practical use case - watch 3D on your TV - one person only. Maybe for you it's fine, but most people would like to share the experience.

3DS tech is great for what it is, but it's in no way ready for prime time in a full-sized television.

Welcome to Rivendell, Mister Anderson.

The NEW 3DS with tracking avoids the big problem of 3D without specs

The NEW 3DS has a camera that tracks you and is designed precisely to correct this problem. All the reviews indicate that this implementation is successful, including among reviewers who had exactly the same experience you describe with the older version.

Yeah, I have a new 3ds and it's a ton better. But the problem is that it's limited to ONE person. Two faces show up and it gets horribly confused and everyone sees a horrible mess.

And it's not foolproof - if it loses face tracking it will revert modes and you'll see a mess for a couple of seconds until it regains lock.

So when it's not working, it's the same as the 3ds, when it works it's wonderful. But you can really tell when it stops working so it's not only not 100% reliable, but when it fails the mess is unwatchable and headache inducing.

It's sorta like samsung's laughable attempt at it during CES - turn it on and everyone wanted to throw up.

Up to your last sentence, I agree with you. For ONE person, it is not "laughable", but a major step forward in watching 3D. And it works almost all the time for me.
