* Specs

Leap Motion 3D Somatosensory controller mouse Gesture Motion Control for PC or MAC Brand New FreeShipping

Features:

The Leap Motion Controller senses your hands and fingers and follows their every move.

It lets them move in all that wide-open space between you and your computer. So you can do almost anything without touching anything

It's the tiny device that just might change the way you use technology.

It's a super-wide 150° field of view and a Z-axis for depth. That means you can move your hands in 3D, just like you do in the real world.

The Leap Motion Controller can track your movements at a rate of over 200 frames per second.

Package Includes:

1, Leap motion Controller

2, 2 custom-length USB 2.0 cables

3, Welcome card

4, Important Information guide

Minimum System Requirements:

Windows 7 or 8 or Mac OS X 10.7

AMD PhenomTM II or Intel® CoreTM i3 / i5 / i7 Processor

2 GB RAM

USB 2.0 port
