Kinect originally debuted as an Xbox 360 accessory for motion sensing so you could play games with your hands or body. Xbox One forced Microsoft to rethink its entire approach to Kinect.
Dubbed the Azure Kinect Developer Kit (DK), the PC peripheral includes Microsoft's latest AI sensors like the time-of-flight depth sensor in the HoloLens 2, and a 7-microphone array for computer vision and speech purposes. It also includes a 12-megapixel RGB camera and a 1-megapixel depth camera. Developers were already using Kinect sensors for research, apps, and many other alternative uses.
