Microsoft will release sometime in 2014 a new Kinect for Windows which will feature the same set of technologies as Xbox One’s Kinect sensor. The new Kinect will feature a wider field of view, high-definition color camera, better depth detection, improved noise-isolating multi-microhpone and more accurate skeletal tracking.
Both the new Kinect sensor and the new Kinect for Windows sensor are being built on a shared set of technologies. Just as the new Kinect sensor will bring opportunities for revolutionizing gaming and entertainment, the new Kinect for Windows sensor will revolutionize computing experiences. The precision and intuitive responsiveness that the new platform provides will accelerate the development of voice and gesture experiences on computers. [...] All of this means that the new sensor recognizes precise motions and details, such as slight wrist rotation, body position, and even the wrinkles in your clothes.
