Sony PlayStation creator's patent application would cover controllers that read players' psychological and physical responses in real time during game play in order to drive dynamic responses from the software. Bio-data would be captured, analyzed, and then used to alter the setting or state of the software or game. This would potentially allow for an automated change of various settings related to a player's comfort level and state of mind while playing. It could also allow for software to cater to the player's moment-to-moment experience on an individual basis.
Sony described a number of potential uses for this technology. Examples included reading a user's stress level to dynamically adjust a game's difficulty, increasing a weapon's accuracy if a player's level of frustration reaches a certain threshold and altering in-game characters who can respond to the player's current state of mind.
