Video games can evoke a range of different emotions, which play an important role in positive player experience. The emotions among game play are real enough for player to response with bodily awareness and uncontrollable biological responses. Through biofeedback devices, we hope to measure different emotion responses evoked by video games, such as Electroencephalography, Galvanic skin response and Heart rate monitor etc. This finding allows us to better assess the game experience and evaluate design choices, while also increase games’ potential for positive impact on society. And further application is hoped to create new game features and contents based on physiological signals.
