Sony Computer Entertainment of America have filed a patent, for a system using coffee mugs to play a video game. Now they've filed one to make your laughter into a controller for the PlayStation 3 - Reports Kotaku.Above is figure 17: "Ha Ha Ha." This is part of the metadata set going into the PlayStation 3, through a microphone and the PlayStation Eye camera. The patent application says it would identify body gestures, facial expressions and the like to deduce the emotion of the players. It's apparently got high-five recognition heuristics, too.
It's also attuned to sadness, anger, joy, interest and yes, boredom.
