They misunderstood the patent filing. Its impossible for the kinect sensor to detect how many people are watching, people could just point the sensor to a wall or off to the side so it looks like only one person is present. "The limitation may comprise a number of user views, a number of user views over time, a number of simultaneous user views, views tied to user identities, views limited to user age or any variation or combination thereof, all tied to the number of actual content consumers allowed to view the content." thats straight from the patent description, it just seems like an option to rent a movie lets say, for either one view or multiple views within a certain time frame, or allow multiple accounts to access the rented movie. Stop getting your panties in a knot
