iOS enters the third dimension

Vodpod videos no longer available.

Companies like Sony and Nintendo are defiant that in one way or another, 3D entertainment is the future. The former relies on fancy TVs, glasses and a PS3 whereas the latter is marketing their latest handheld, the 3DS, as a better alternative, doing away with the need for glasses and instead using a dual-layered screen to generate 3D images. But what if you didn’t need either or those solutions? A pair or developers from the University Joseph Fourier have created a tech demo for iOS devices that creates the illusion of 3D on existing 2D Apple hardware (via Slide to Play).

The App called i3D (available on the App Store now) was developed by Jeremie Francone and Laurence Nigay and uses the front-facing camera to track your face as move the device around. Since your head stays still (or at least should), i3D changes the on-screen image in real time according to its position relative to your head. Or, to put it another way, iPad 2 or iPhone 4 + i3D + head = 3D images. The video above shows just how impressive the demo is at the moment and the potential for this kind of technology rather than investing in expensive glasses or multi-layered screens. The downside – other than i3D currently only showing five proof of concepts, one of which being Mii heads so it’ll probably be pulled soon – is that no matter how cool this kind of thing is, it’s generally seen as a gimmick. Nintendo’s previous DS has a DSiWare title called Looksley’s Line Up or 3D Hidden Picture in Japan, that was pretty neat but puzzlingly not a concept adopted by other developers. Maybe now that i3D has been made for iOS devices, there’ll be more interest from smaller indie studios who regularly create iPhone games. I hope so because in the right hands this kind of thing could be awesome.
