Claim Text:
1. A method to control a pointing device with an angular rate sensor (ars), said method comprising: generating an ensemble of orthogonal unit vector associated angular rate signals by at least one angular rate sensor, each angular rate signal representing an angular rate in a dimensional space for a mutually orthogonal unit vector direction of said dimensional space; amplifying at least one of said angular rate signals with an amplification function that is a non-linear function of at least one of said angular rate signals; determining (x,y) coordinates of a cursor on a screen from said angular rate signals, one of said (x,y) coordinates corresponding to one of said angular rate signals; applying a decision criterion to determine a stationary state of the pointing device from said unit vector associated angular rate signals, and updating, in response to determining the stationary state of the pointing device, a zero point offset of the angular rate sensor.
