This kind of language from the patent heavily suggests the likes of Kinect's new incarnation could support this system, but it isn't limited to the Xbox One, Kinect or indeed any specific device. However this little patent won't do too much for the confidence of those already shaken by Xbox One's muddled second-hand trading policies.
