Looks like Microsoft is finding new uses for Kinect tech and not gonna wait to make it so much more than it already is. This is the kinda potential you expect from that tech. Exciting stuff that can have many uses.

(http://www.engadget.com/tag/autostereoscopic)Glasses-free 3D (http://www.engadget.com/tag/autostereoscopic) has taken several forms, but most have a critical flaw -- viewers have to stand in predefined locations (http://www.engadget.com/2010/03/25/new-glasses-free-3d-tech-uses-per-pixel-prisms-for-zero-crosstal/) to get the effect. That just won't do, so Microsoft's prototyped a new approach, and it's one of the wildest we've seen. Taking a cue from Project N (http://www.engadget.com/tag/Natal/)... we mean Kinect (http://www.engadget.com/2010/06/13/microsoft-kinect-revealed-project-natal-finally-gets-a-name/), cameras track the face while a special wedge-shaped lens traps bouncing light, and after the beams have reached a "critical angle," it exits towards the viewers eyes, aimed by programmable LEDs at the bottom of the screen. Since the system can beam a pair of simultaneous images to two different places, the obvious use is stereoscopic 3D, but researchers found they could also send different images to different viewers, as a sort of privacy screen
