Sony's just won a patent that seems to suggest it's working on a controller that actually heats up or cools down as part of the game. Your gun overheated? So will your controller. Throw a fireball, and your hand heats up. Try to pull someone out of an ice-covered lake and your hands freeze. This sounds awesome.
Apparently it's all based around the Move controller, which would have temperature controlled bands wrapped around it that get hotter or colder as part of the game's feedback. Sony's given us quite a few examples of how it could be used, like those listed above, but it also throws in a biometric sensor into the mix that'll detect how sweaty your hands get. That's kind of rank, but also a great indicator of how stressed you're feeling as the bullets start flying over your head.
We, of course, have no idea if Sony's really doing this. But it's such a detailed patent, and a fantastic idea, that it absolutely must be at the very least considering it. I don't know about you, but it'd bring a whole other dimension into my Street Fighter tournaments. Maybe I wouldn't throw quite as many hadoukens if my controller got red hot.
