For Kinect MS bought or licensed tech from PrimeSense. Neither MS nor PrimeSense invented or own "motion detection" in general or even just "hans-free motion detection", just like neither does Nintendo nor Sony, they just invented and patented some of the possible implementations, focusing on ones that could become affordable in time for their needs. MS in particular for Kinect commissioned from PrimeSense a lower res, lower frame rate, no CPU onboard, and for these reasons cheaper version of their motion detection tech. For next versions of Kinect obviously the most powerful versions of the tech will already be cheap enough, naturally.
