This is the Leap Motion.

Reporting by Stacey Higginbotham for GigaOm:

The company, which was founded in 2010 has built a peripheral device that you plug into a computer or laptop that can enable a gesture-based user interface that incorporates all directions — not just a flat perspective. Some have described it as a Kinect for computers. The device has a 150-degree field of view and can accurately track the movements of all 10 fingers down to the 1/100th of a millimeter, which is apparently pretty darn impressive according to reviewers.
