Sony has filed a patent for biometric game controllers.
As spotted by Siliconera, the listings describe sensors built into the DualShock 3 and Move controllers, as well as a proposed handheld, which measure skin moisture, heart rate and muscle movement.
Included in the filing are a number of possible implementations for the system.
Weapon handling could change depending on how nervous the player is. For example, when using a sniper rifle, the more relaxed your heart rate, the steadier your aim.
Players could tense their grip to withstand an attack or charge a shield.
An in-game character could start sweating if the player's heart rate increases.
Your in-game health bar could deplete more rapidly if you're nervous.
A player's attacks could differ depending on heart rate.
Background music and scenery could change depending on your stress level.
A game's difficulty could adapt to a player's stress level.
