A start up has developed a new 3D technology for controlling computer devices through motions.

Michael Buckwald, chief executive and co-founder of Leap Motion developed 3D-gesture sensing controller that allows touch-free computer interaction for the users. Experts have been working on the development of alternatives to keyboard and mouse for operating a computer.

The venture based in San Francisco has developed what it calls the most naural user interface for operating computing devices. The movements of finers and hands within a short distance of the computing device allow virtual pointing, swiping, zooming, and painting. The company will begin the shipment of the new 3 inch device this week.

"We're trying to do things like mould, grab, sculpt, draw, push. These sorts of physical interactions require a lot of accuracy and a lot of responsiveness that past technologies just haven't had," said Mr Buckwald.

He also said the device is capable of tracking hands and all 10 fingers a it is 200 times more precise than Microsoft's original Kinect. The device relies upon three near-infrared LEDs to to illuminate the owner's hands, and then employs two CMOS image sensors for a stereoscopic view of the person's actions.
