Abstract: A player's mental attributes may be determined and used in interacting with video games or training programs through a video game system. The video game system may include a biometric controller such as an EEG device or configured to detect a level of attention and a level of relaxation of the player through electrical impulses exhibited by a player's brain and/or pulse oximetry monitoring device. These determined levels of attention and relaxation may be interpreted by the video game system into one or more actions in or changes to a video game environment. Additionally or alternatively, video games may be used to train a player to lower stress and improve concentration or focus. The games may be entertainment based or non-entertainment related (e.g., instructional/exercise focused). Further, combinations of controllers may be used to control various aspects of a video game or training program to exercise both body and mind.
