Leap Motion’s controller is a touch-free device that allows users to control their computers via hand gestures in three dimensions. The Leap Motion Controller senses how you move your hands, the way you move them naturally and with a wave of a hand or lift of a finger you can use your computer. So you can point, wave, reach, and grab. Even pick something up and put it down. Just like in real life.
The Leap Motion controller is a small USB peripheral device which is designed to be placed on a physical desktop, facing upward. Using two monochromatic IR cameras and three infrared LEDs, the device observes a roughly hemispherical area, to a distance of about 1 meter. The LEDs generate a 3D pattern of dots of IR light and the cameras generate almost 300 frames per second of reflected data, which is then sent through a USB cable to the host computer, where it is analyzed by the Leap Motion controller software using “complex math” in a way that has not been disclosed by the company, in some way synthesizing 3D position data by comparing the 2D frames generated by the two cameras
The Leap Motion Controller senses every little move they make, and every big one, too. Technically speaking, it’s 8 cubic feet of interactive, three-dimensional space.The Leap Motion Controller tracks all 10 fingers up to 1/100th of a millimeter. It’s up to 200 times more sensitive than existing motion-control technology. The Leap Motion Controller knows the difference between your fingers. It can tell an index from a pinky from a thumb and when you switch between them. It even understands when you bend, flip, or fold your hands.
Leap Motion has interesting portfolio of apps for example you can mold a masterpiece in 3D, play air guitar for real, fly a plane with your hands, build 3D models, Sketch, draw, and paint with finger, sculpt as easily as with clay and even use real pencils and paintbrushes.
