Video: Next-gen Kinect sensor.
The sensor inside Kinect was created by PrimeSense, who demonstrate the next generation model called Capri in this video.
Capri is 1/10 the size of previous models, and the company says “we have been able to improve on all aspects of the system” in the device, which can be integrated into tablets and smartphones.
Microsoft is actually only one customer using the system, and does not licence it exclusively. Other companies also using the technology include iRobot, Matterport, and Asus.
