head-tracking 3D visualization app

head-tracking 3D visualization app


the 3D visualization app for iPhone and iPad uses head-tracking to generate its effect


glasses-free 3D visualization is possible on the iPhone and iPad with a to-be-released application designed by french engineers
jeremie francone and laurence nigay of the laboratory of informatics of grenoble. in the technology, the position of the user's head
is tracked with the device's front-facing camera, creating a convincing 3D effect that alters with the viewer's change in perspective.
requiring no special glasses, the visualization varies from the kind of effect used in many 3D technologies because it tricks the brain
into believing that there is depth behind the screen, rather than that images are protruding from the glass.

while certainly the application offers expanded opportunities for gaming and visualizations, it can also provide expanded screen space
for the more efficient organization of and facilitated access to widgets and applications.

the team cites the work of american engineer johnny lee, who used similar techniques to generate a 3D effect on wii systems.
chris harrison's 'facetracker' application for laptops also implements head tracking for 3D visualizations.

is this how the 3DS works as well?

no. The 3DS uses two lcd screens, actively creating two images. One that is "aimed" at your right eye, and the second at the left eye.
