If you are not familiar with Leap Motion, it is like a touchscreen without a touchscreen. It has so many uses like drawing in the air for an art program. Then there is the FPS that uses your fingers for a controller.
The Leap Motion controller uses a small USB peripheral device, two cameras, and three infrared LEDs, and you have a 1 meter hemispherical area to work your magic. It’s like Tom Cruise’s interface from Minority Report, but without the gloves!
If you want to get in on this action, it should be available in late July for a price of $79.99.
