Minority Report-Style Gesture Control
This innovature gesture control device ties into your Windows or OS X computer allowing you to control thing with the wave of a hand!
Leap Motion plugs into a USB port and the tiny device allows your Windows 7, 8 OS X 10.7 and 10.8 machines to detect the airspace in front of it and determine what sort of gestures you're making.
The Minority Report-like interface is said to be 200 times more accurate than Microsoft's Kinect. Available in May.
