This mindblowing video has been viewed more than 7 million times since Leap Motion put it on YouTube last May. Basically the engineers at Leap Motion have invented the 3D user interface of the future. You don’t use a keyboard and mouse; you don’t even use a touch screen. You just move your fingers in the air, and, as if by magic, with zero latency and pinpoint accuracy, stuff happens on your screen. Think of Microsoft’s Kinect controller, but way better. Leap Motion claims its device is 200 times more accurate than anything on the market and can track your finger movements down to 1/100th of a millimeter.
The first version of the product will be delivered in a little plastic hockey puck that you connect to your laptop or desktop computer. This little device will start shipping early in 2013 at an incredible price — only $69.99 gives you a new toy that isn’t quite like the user interface from Minority Report, but it’s not that far off, either.
