Abstract: A method of user interaction with an entertainment device comprises generating an audio-visual output for use with audio-visual reproduction equipment, initiating an audio-visual event as part of the generated audio-visual output, receiving input data from one or more game control devices associated with the entertainment device, analyzing the received input data to evaluate an involuntary physical response by a user interacting with the or each game control device occurring within a predetermined period associated with the initiation of the audio-visual event, and adjusting subsequently generated audio-visual output responsive to the evaluation of the user's involuntary physical response.
