[using]...the iPad's front facing camera to provide a convincing 3D effect on the iPad...Jeremie Francone and Laurence Nigay from the Laboratory of Informatics of Grenoble put together this demo video showing how user tracking can be used: 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.
Francone and Nigay were inspired by the work of Johnny Lee who built a similar system using a Wii system. The app does not yet appear to be available for download....
