You all might heard about KINECT.
Kinect is one of the most revolutionizing piece of hardware that i have heard about in few years.Kinect is a motion sensing input device by Microsoft for the Xbox 360 video game console and Windows PCs.
Have you ever thought of playing some games without any consoles, your hands are your stylus. All the gestures you make is only what you need. Who might have thought it few years back that your motions could be sensed and the device can understand it . Not, just your gestures, but it can work to your voice commands as well.
Kinect builds on software technology developed internally by Rare, a subsidiary of Microsoft Game Studios owned by Microsoft, and on range camera technology by Israeli developer PrimeSense, which developed a system that can interpret specific gestures, making completely hands-free control of electronic devices possible by using an infrared projector and camera and a special microchip to track the movement of objects and individuals in three dimension. This 3D scanner system called Light Coding employs a variant of image-based 3D reconstruction.
The Kinect sensor is a horizontal bar connected to a small base with a motorized pivot and is designed to be positioned lengthwise above or below the video display. The hardware device has a RGB camera, depth sensor and multi-array microphone.
