As we recently reported, the new iPad 2 has been mounted with a front facing camera. Apart from allowing individuals to video chat with ease, Apple also gave developers access to the camera in the hope that they create new and exciting apps and games.
With such access a team of researchers at the Grenoble Informatics Laboratory in France have recently developed a 3-D style interface for the iPad 2. The researchers use the camera to track the user’s gaze, allowing the iPad to change the image on the tablet’s display to shift its perspective. They call this a “spatially-aware mobile display.”
