In search of suitable methods for measuring the affective state of video-game players, this study investigates the hypothesis that the player's state of arousal will correspond with the pressure used to depress buttons on a gamepad. A video game was created that would detect the force of each button press during play. It was found that as the difficulty level of the game increased, players would hit the gamepad buttons significantly harder.
