An Israeli start-up company called XTR3D has developed a gesture recognition system that will allow users to control electronic devices with just a move of their hand.
"Although the Israeli firm follows in the footsteps of Microsoft's Kinect, the multi-directional gesture control gaming console that was launched last year and has since been selling like hot cakes despite the average $200 price tag, its technology is quite different.
The Kinect has depth sensors, multi-array microphones and RGB cameras that provide the software with the information it needs to track both voice and gestures.
XTR3D, on the other hand, uses ordinary 2D cameras - such as a webcam of a computer or the one in your smartphone - to extract 3D out of a 2D image.
This creates the same three-dimensional effect as on the Kinect."
