Well, this sure looks neat. Microsoft's Applied Sciences Group has come up with a new interface system for computers that uses a camera positioned behind a transparent OLED screen to create a touchscreen you don't have to touch.
Yep, because the screen can essentially see you, you're able to use it like a normal touchscreen or step back, wave your hands around, and use gesture-based controls like Microsoft showed off with Kinect.
What's the practical use of this tech? Heck if I know, but you'd better believe the gang at Microsoft is working hard of figuring that out as we speak.
