LEAP Motion sensor - DEMO by ENGADGET

Now there are also other movies with a more 'live' demonstration of the amazing leap motion sensor. Here is one from engadget. This really seems to be true!!

LEAP Motion sensor - Novel gesture-based interaction at high accuracy

Leap represents an entirely new way to interact with your computers. It’s more accurate than a mouse, as reliable as a keyboard and more sensitive than a touchscreen.  For the first time, you can control a computer in three dimensions with your natural hand and finger movements.

This isn’t a game system that roughly maps your hand movements.  The Leap technology is 200 times more accurate than anything else on the market — at any price point. Just about the size of a flash drive, the Leap can distinguish your individual fingers and track your movements down to a 1/100th of a millimeter.

This is like day one of the mouse.  Except, no one needs an instruction manual for their hands.

If this is for real they really have a breakthrough technology at their hands. This would really enable the introduction of gesture-based interaction into medicine with high accuracy and flexibility with minimal movements.
