You remember the movie Minority report? Tom Cruise and his fellow officers were solving pre crimes! I remember that the computers they were using could be controlled by waving your hands in front of it. You could select and move things on the screen, without using a mouse or a keyboard.
With Leap Motion you will now be able to solve pre-crimes on your own laptop! Well maybe not solve crimes, but this gadget will give your laptop the ability to be controlled by hand gestures! Goodbye mouse and keyboard! This gadget is shipping out in May and will be available on windows 7 or OSX 10.7 and 10.8.
