The Leap Motion Controller is a small USB device that plugs into your computer. Using LED lights and camera sensors, the Leap Motion Controller scans an area of roughly 8-cubic feet (2x2x2) above the device. It tracks both hands and all 10 fingers as they move through the open space between you and your computer, the special software detects your hands and fingers and translates the data into information for your computer.
With over 200 apps in the Leap Motion App Store, you have access to fun, new ways to play, create, and explore using just your hands and fingers in the air. You’ll find a wide variety of dedicated apps for gaming, music, art, science, productivity and much more. And, your Leap Motion Controller comes bundled with select apps for free too!
