Eye-Tracking Trick Brings Glasses-Free 3D to iPad 2
By Chris Brandrick
Why wait for the iPad 3, 4 or even 5? A tablet that can offer glasses free 3D is here now, thanks to a neat iPad 2 tech demo.
OK, so this isn’t actually real 3D, but the neat little visual trick, which has been made possible due to the introduction of a front-facing camera on the iPad 2, sees a seemingly live 3D image on the tablets 2D screen. This little bit if visual magic, dubbed Head-Coupled Perspective (HCP), was created by a French-based team of individuals at the Engineering Human-Computer Interaction Research group.
Their clever trick uses a live feed from the iPad 2’s front-facing camera–coupled with some custom software–to track your head in real time. The result is pretty neat–the on-screen image seems to dynamically change perspective depending on the position of your head relative to the iPad. Check it out for yourself:
