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.

Of course using movement to create visual effects like this isn't anything new. Nintendo achieved a similar visual trick with the Nintendo DSi, and some iOS apps employ a similar trick by using the built-in accelerometer to simulate depth., But this cool little tech demo (which has also been demoed on an iPhone 4) offers a glimpse at what could be achieved if a few clever developers got together.
