The past has shown that the more sensors Apple adds to its iDevices, the more amazing things developers are able to do with them. From Instant Heart Rate to Word Lens, not to mention GarageBand, we’ve seen it all. This week some French folks have now managed to go even further using the iPad 2′s powerful processor and front facing camera.

Combining head tracking and 3D technology, they managed to enable the iPad 2 to display 3D elements, without the need to wear special glasses:

We track the head of the user with the front facing camera in order to create a glasses-free monocular 3D display. Such spatially-aware mobile display enables to improve the possibilities of interaction. It does not use the accelerometers and relies only on the front camera. [sic]

As you’ll see in their video, it’s very impressive, and could make iOS gaming even more incredible than it already is. Check it out:
