Methods and systems for dynamic calibration of movable game controllers

摘要

A video gaming system includes a wireless controller that senses linear and angular acceleration to calculate paths of controller movement over a broad range of controller motion. The system also includes an electromagnetic alignment element, such as a set of LEDS. The controller includes an additional sensor to sense light from the LEDs over a relatively restricted range of controller motion, and use this sensed light to dynamically calibrate the controller when the controller passes through the restricted range of motion over which the sensor senses the light.

1. A method for controlling a video game using a wireless game controller, the method comprising:
sensing linear and angular accelerations of the controller over a broad range of controller motion; sensing an electromagnetic alignment element over a narrow range of controller motion, less than the broad range of controller motion, the narrow range limited to an alignment between the electromagnetic alignment element and the controller; tracking the sensed linear and angular accelerations to calculate a path of the controller as the controller passes through the broad range of controller motion outside of and including the narrow range of controller motion; computing, from the calculated path, an animation path of the controller and driving an animation of an object from the animation path; dynamically correcting the animation path responsive to the sensed electromagnetic alignment element as the controller passes through the narrow range of motion; and restricting the calculated path based upon a mechanical model of a human figure.
