Patent ID: 8425295

Claim:
A method of rating the intensity of game play of video games, including a first video game and a second video game, based on energy expenditure of a user playing the video games, the method comprising the steps of: a) selecting the first and second video games to rate; b) determining whether the first video game and the second video game require the user to expend energy in excess of an approximate resting energy rate; c) testing the first video game and the second video game by having a plurality of users play the first and second video games for at least one hour intervals; d) measuring energy expenditure of the plurality of users in step (c) with physiological sensors; e) calculating the energy expenditure of each of the plurality of users during a predetermined time period of game play; f) calculating an average energy expenditure of the plurality of users for each of the first and second video games; and g) categorizing the first and second video games based on the average energy expenditure as one of at least low intensity, moderate intensity, and high intensity for comparing the intensity of game play of the first video game to the second video game.
