When Microsoft debuted the platform, then known as Project Natal, the company promised it would enable an entirely new type of gaming, one in which your entire body would serve as the controller.

Microsoft took note of that success and doubled down on it, declaring that every next-generation Xbox would ship with a Kinect included. Polygon has published a truly excellent deep dive into the design and development of Kinect, from conception to the Xbox One. The story they tell is fascinating.
