Researchers demonstrate glasses-free 3D on iPad 2

Impressive demo shows huge potential for tablet gaming and entertainment

French researchers belonging to the EHCI Research Group have developed unique software for the iPad 2, one that allows for 3D viewing without the need for cumbersome glasses.

According to macstories, the technology is based completely on manipulation of the front-facing camera of the iPad. The camera would pick up and track any movement of the user’s head, which can then ultimately allow for 3D imagery on the screen. The “spatially-aware mobile display” could potentially open the door for more immersive gaming sessions or general tablet usability.

The “head-tracking” trick for 3D viewing is also reminiscent of a Toshiba prototype laptop that was shown off earlier this year at CES. The latter uses a similar concept where the front-facing camera tracks user eye movement in order to properly display glasses-free 3D video.

Whether or not the same technology can be developed for other tablets or even notebooks is currently unknown, but the ability to display any sort of 3D video without extra spectacles is quite exciting nonetheless. The official demonstration below is definitely worth a look.
