Stressed? Want to know if you are while you're gaming, well, according to a series of patents that Sony have filed recently, they might be adding biometric sensors to PlayStation 3 controllers and to a handheld resembling the PlayStation Vita.

Will gaming change if it [the game] knows how you feel? Well, think about it... if a game can detect you're stressed by holding the controller down - it might tone down the AI, difficulty, etc. If it's a horror game, it might amp it up, making you more scared and making you hold the controller ever so tightly.

The sensors in the patents would measure the moisture of your skin, heart rhythm, and muscle tension. This really could change everything, again, and is something I expected from Apple (snicker), but if Sony incorporates this into the PlayStation 4, it really could change the way games are not only played, but made. It would change everything, from background music and facial expressions to running speed and weapon accuracy.

The possibilities of something like this are quite endless.
