Face Tracking Perspective on the iPad

Jeremie Francone and Laurence Nigay a part of the Engineering Human-Computer Interaction (EHCI) at Grenoble Informatics Laboratory (LIG)—wow that was long—created this demo of simulated 3D perspective on an iPad without the need for 3D glasses.  They are using face tracking with the iPad 2’s front-facing camera to change the display perspective as you look at the iPad from different angles.

Brilliant idea!  How long do you think it will be before developer start to use this approach for iPad games?
