Kotaku's Luke Plunkett delves into a newly disclosed Microsoft patent that covers spying on people in their homes using cameras attached to their TVs, in order to levy fines against them for allowing too many people to watch movies at once:
Basically, when you buy or rent something like a movie, you’ll only be granted a “license” for a certain number of people to watch it. If Kinect detects more people in the room than you had a licence for, it can stop the movie, and even charge you extra. So if Microsoft has its way, you won’t just be renting movies any more. You’ll have to decide how many people are watching, and no doubt pay more. And if one extra person turns up to your movie night? So help you God, you are going to pay.
Of course, big companies patent all sorts of stupid ideas, many of which never get incorporated into products. But hey, now you know that researchers at Microsoft sit around spitballing ideas like, "Wouldn't it be awesome to spy on our customers in their homes so that we could fine them for having too many people over to watch movies? Wonder if anyone is Hollywood would give us preferential access to movies if we could promise them that they could do nose-counts of people in their own homes?"
