GoMonkey goes Minority Report

GoMonkey is a technology that gives people the possibility to interact with a (computer) screen by gestures. So they don't have to use a mouse, a keyboard or some other device to communicate with a screen, they just use gestures to navigate the content on the screen.

It looks like the screen used in the movie Minority Report, but the gestures are more simple. Have a look at their website if you want to see a short movie on how it works, btw they use 2 cameras to do the gesture recognition/tracking. Unfortunately the site and the narration are in German but you will understand the movie anyway.
