Kinect is a line of motion sensing input device, which is based around a webcam-styled add-on peripheral. It facilitates interaction with a console (or computer) without requiring a controller, via a natural user interface (NUI). All that one has to do is use gestures and speech commands to get up and going with the Kinect.
The Kinect sensor is a horizontal bar attached to a small mechanical pivot designed to be positioned vertically while using. Kinect uses an RGB camera, depth sensor, and multi-array microphone running proprietary software that allows a complete body 3D motion capture and facial and voice recognition capabilities.
Kinect’s depth sensor includes an infrared laser projector incorporated with a monochrome CMOS sensor which captures data for the video in 3D.
