Leap Motion fully-enables control of your computer with hand and finger gestures. The tech is so accurate, the manufacturer claims it to be just as accurate and precise as using a keyboard and mouse and more sensitive than using a touchscreen. (see video demo below)
For the first time, you can control a computer in three dimensions with your natural hand and finger 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.Priced at only $70... it may be a gadget worth trying..!!
