I'm pretty sure no-one thought that apple released the iPad 2 forgetting to say that it was 3D compatible, but this surely gives a way to pseudo 3D, which is pretty neat, better to have a cool even if fake 3d effect on a 2D screen if they can refine this method
As opposed to TV, which have a....fake 3D effect on a 2D screen?
 
Just a few things that have probably already been said-

This isn't 3D at all. It's a 2D image that is adjusted through headtracking. If you move a 3D character in a game using a controller; that isn't mimicking a 3D display.

When only cinema and the 3DS was the consumers gate to 3D this forum hated it (it's probably buried now but the thread about Apple looking into 3D displays for the iPod is hilarious. Almost as funny as "thread 500"). When Apple does full 3D will it then become accepted? :D

Still it's a nice effect. I've played DS games in the past that used a similar tracking method and it worked well.
 
I'm not arguing that this isn't 3D. I'm arguing that this video is deemed as glasses-free.

Did you actually think about what you wrote, before you wrote it?

Clearly, in the video there were no glasses of any kind involved (in the video you posted the gentlemen only used glasses because they were a convenient way to attach the IR sensors to his head). So, if you aren't arguing that this isn't 3D, and it clearly uses no glasses, what exactly is your argument?

I don't know about anyone else, but at the 1 min mark where the "targets" are being shown, they definitely look like they are protruding/jumping off the screen. I certainly don't have any experience or knowledge of this technology, but as far as I am concerned that is 3D.

You are not alone. Even in the video that Mooey posted the guy clearly states how the targets appear as if the are out in front of the screen.
 
They did this with the Nintendo DSi back in 2009.

The game is available in the DSi Ware Store (called Looksley's Line Up). It´s quite funny because the changing of the perspective will reveal the solutions to each diorama and the effect is done quite well.

Back then when Nintendo announced that their next iteration would feature 3d I just thought that they would implement this form of "pseudo" 3d in every game. The problem in real life: You only get the 3d effect when you move your head or your device - So it´s the totally opposite concept of the stereoscopic screens like in the 3ds or some new android phones where you can only see the effect when you look straight on the device! You have to experience both - Funny thing: You can download the DSi game on the 3DS and play it there and afterwards some 3DS 3d game to really get the idea how the two techniques behave in real life. Obviously both have their advantages!

What would be impressive is some combination of the two: "Real" 3D imaging like on the 3ds combined with headtracking..

EDIT: Some of the problems with Jonny Lees awesome concepts: You can only do it alone, the effect doesn´t work if more people are staring at the tv, and it isn´t possible with movies it´s only possible with real time rendered objects! As you can see the stadium at the end is totally flat, as opposed to how the stadium would look like with glasses and shot with a 3d camera.

But after getting my 3ds last week (together with PES 2011) I have to conclude that the 3d of the 3ds is better and more impressive even though my eyes start to hurt after playing for an hour or so..

Because they achieved this game with the DSi (133 Mhz ARM) I don´t think that it taxes the cpu very much..

This will work because it neatly sidesteps the fundamental issue that plagues glasses-based 3D.

There are two component parts to stereoscopic vision: the focussing of the individual eyes and the convergence angle between the two eyeballs. Millions of years of evolution has linked these two sub-systems together in the unconscious. In order to view 3D images on a screen using 3D glasses, the individual eyes need to remain focussed on the physical images on the screen, while the convergence of the two eyeballs needs to change in order to track the virtual images that are appear closer to or further away from the viewer. This requires the decoupling of the focus from the divergence, requiring an almost conscious effort, leading to the fatigue that many have experienced.

All 3D is a 2D image that is manipulated in such a way that the brain is tricked into seeing 3 dimensions. How is this any different exactly?

Because of on-screen motion during gameplay, is that why Nintendo when with the Lenticular Lenses?

I'm wondering how this head-tracking technology would work in-game...
 
Fake?

Fake?

Anyone else think it's a fake? I don't see how the front facing camera could possibly follow his head _way_ off to the side the way it does... but I could be wrong (don't have an iPad2 to see how wide angle the lens is)
 
I'm blind in my right eye, and this will allow for me to experience 3D for the first time. Existing methods require binocular vision but this works for me, and I was pretty darned convinced. I don't see how you guys can expect better than this, seriously!
 
I remember seeing this on the Wii and being really amazed, I think something like this would be really slick with stereoscopic 3D on top of the head tracking.

I wonder if by using the gyros also they could allow the screen to tilt farther, although I suppose if you tipped it farther and moved your head you would lose the effect.

I'm really sick of the 3D gimmick trying to make a comeback. We can only see in 2D. All the "3D" can do is trick us into havung depth perception on a flat screen.
 
HoloToy does this...

HoloToy does this, and did it in August 2010.

Not fake. This has been demonstrated on the Wii and the DS. Very simple to do actually.
 
How do you find it on the App Store?
It's called "iDesktop VR". But it is NOT the version shown here. It's a version that is based on the accelerometer only. There is no head tracking involved, so the effect can't exactly be compared. But it gives you the idea.
 
All 3D is a 2D image that is manipulated in such a way that the brain is tricked into seeing 3 dimensions. How is this any different exactly?

I'm not a fan of 3D movies (too gimicky) but they are different technologies with different results. With this app, cool as it is, you have to move in relation to the display to get any sort of depth. As far as I can tell, this would not work for any movies/games where the camera is moving. That, and there appears to be no "z axis" depth unless you're swinging your head back and forth.

As cheesy as it is in movies, at least you can sit still in your seat and have the paddleball fly into your face. This demo appears to be more like, "you can see the paddleball string if you tilt your head to the side".
 
Combine this with 3D glasses technology, and you will have everything to simulate real life 3D: seeing an object from two different angles at once + being able to change your viewing angle by just moving your head! This will probably look very cool but I think this head tracking 3D stuff is enough for most things now.
 
Just so people are clear about what's going on here, there is only a single on-screen image at all times, and both of your eyes are seeing the exact same image at once.

This illusion will NOT appear to be 3 dimensional if your head isn't moving and the screen isn't moving. Either your head or the screen must be moving around for you to sense a partial illusion of 3 dimensional space.

Your brain uses several different cues to build its mental representation of where things are in 3 dimensional space. Each of these different types of spatial cues contribute a different amount of information that you build your mental space representation on. The type of dimensional information that this illusion delivers is the least effective 3 dimensional cue that your brain uses, meaning this will be a relatively weak type of 3D illusion.

Don't get me wrong, it's still cool and will still be fun to play with and may wind up being useful, but don't get your hopes up that this will be a very convincing type of 3D illusion - because it won't be.

Combine this with 3D glasses technology, and you will have everything to simulate real life 3D: seeing an object from two different angles at once + being able to change your viewing angle by just moving your head!

Nope, there would still be some missing 3D cues that your brain uses to form its full 3 dimensional image.

As you focus your eyes on an object that is nearer to your face, your eyes start moving into a more "cross eyed" position, and when you focus on an object that is further away then your eyes's gaze moves further apart into a more straight-forward view. The brain uses your eye gaze separation amount as part of its 3 dimensional input information.

Also, when you look at an object that is nearer and further to your face then your eye lenses change shape to keep the object in focus. The brain uses your eye lens focus-shape amount as part of its 3 dimensional input information.

Both of these 3 dimensional information inputs would still be absent in a head tracking + stereoscopic (glasses) setup that would still be absent.

And there's also a whole bunch more depth perception cues that your brain uses to build its full sense of 3 dimensional space.

What an insanely simple idea for such a cool effect!

I'd love to see more UI tricks using this sort of 3D. Could be some cool effects to see windows actually float some over background items.

Obviously, as others have pointed out... the game potential would be amazing. I guess this is similar to what they use on the Nitendo 3Ds?
 
Only a guess, even though I think it will be a year early, I could see it be calledl IPad 3D.
 
People seem to be missing that to provide the 3D illusion with this effect it requires an almost constant motion, otherwise it will just resemble a flat image of a 3d surface.

This makes any actual use of this kind of silly, and makes the viewing of 3D videos and images still impossible for the iPad This is because both videos and 3D images (.mpo files) have two images sent to each eye separately which this method of 3D is completely incapable of because it requires fully rendered models for viewing.

A parallax barrier, such as the one on the 3DS, or other legitimate 3D viewing method would be required to have any real use, particularly without forcing the user to constantly move their head or the device that they're holding to maintain the 3D effect.
