Microsoft has filed a patent for the Xbox gaming Kinect controller, and it has nothing to do with how well you dance Gangam style. It appears to be designed for figuring out if too many people are watching something on Xbox -- a DVD, a Blue Ray disc, etc. If it detects a couple of people watching, fine. But what if it's a dozen? That might constitute a real audience, and you'd have to pay more for a lisence to show it like you're a theater.
