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.
