Video: Head Tracking for iPad 2 Makes Glasses-Free 3D Display

Jeremie Francone and Laurence Nigay from the Laboratory of Informatics of Grenoble at the EHCI Research Group have created one of the most impressive tech demoes for the iPady. By combining head-tracking technology that uses the iPad’s front facing camera with basic 3D graphics, they’ve developed a glasses-free 3D experience that doesn’t require the accelerometer, but it’s entirely based on the camera and the movements of a user’s head in front of the screen.

Head-Coupled Perspective on Mobile Devices. 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 doesn’t use the accelerometers and relies only on the front camera.The demo with the targets has been inspired by the work of Johnny Lee with a Wii remote.

Glasses-free 3D has been deployed by Nintendo in its latest 3DS portable gaming console, and a series of reports in the past suggested Apple could implement glasses-free 3D gaming for the next-generation iPod touch.
