Abstract
A method and a video game system that maintain the readings of the accelerometer sensor of the remote controller used in conjunction with the video game system consistent over different controllers and different styles of play. The video game system looks at a predetermined time period, when the largest difference in the acceleration vectors for each frame is within a small limit, indicating that the player is holding the controller relatively idle. Then, the video game system averages the acceleration vectors over this time period, and the inverse of the magnitude of this average is used as a normalization constant.
