Of all of the things Minority Report promised at least one thing is finally coming true: the ability to interact with your computer with the flick of a wrist.
Well that is the promise of a small device called Leap Motion. If you’ve ever played with a Microsoft Kinnect, think of Leap Motion as small one of those but attached to your computer.
The Leap Motion controller tracks your hands in 3D space and converts your movements into actions and gestures on screen. The tiny LEDs and infrared cameras tracking your movement can generate around 300 frames a second of data - almost 12 times as much detail as what you see on TV.
Certain kinds of lights directly above your desk can tend to freak it out but clearly it’s struck a chord because computer manufacturers are now starting to build Leap Motion straight into laptops.
There's also a steadily growing app store - mostly of games where you can stroke radioactive trees or play serial killer. You can also use it to read The New York Times and potentially even completely do away with the mouse and computer handsfree.
