http://www.youtube.com/watch?feature=player_embedded&v=_d6KuiuteIA Leap Motion, a San Francisco startup, has created a device (“the Leap”) that lets you control your computer just my moving your fingers over it, as if you were using a touchscreen in the air.
But you can also use it to manipulate 3-D items as well, like working with a 3-D model or rotating 3-D objects and displays–all without special gloves or other controllers. The device, a small rectangular cube that you plug into your computer via the USB drive, simply follows your fingers, or any other object (like a pen or brush) that you stick into the 4 cubic feet above it.
Leap Motion is now taking pre-orders for the $69.99 device but won’t begin shipping it until the end of this year or early 2013. The company is also opening up its developer ecosystem to give software makers a head start on developing new applications.
