Now this right here is some exciting news about glasses free 3d tech. Researchers in France created a proof-of-concept app and video that demonstrates the iPad 2’s ability to create glasses-free 3D effects. Jeremie Francone and Laurence Nigay of the Laboratory of Informatics of Grenoble, EHCI Research Group discovered that by using the device’s front-facing camera to track the head of the user—and therefore determine the angle from which the user is looking at the device—they could create a spatially-aware display. Most notably, the effect does not use the device’s accelerometer at all, instead it relies solely on the front camera. The facial tracking really does give the 3d effect. Amazing.
