Abstract:
1. A method of modifying a pointer signal generated by a handheld pointing device using three dimensional pointing and corresponding to motion of the handheld pointing device, said method comprising the steps of: a) providing an adjustable low-pass filter operable within a gain range; b) generating an angular velocity of the pointing device based on the pointer signal; c) determining a target gain of the adjustable low-pass filter based on the angular velocity and predetermined angular velocity threshold information; and d) filtering the pointer signal using the adjustable low-pass filter with the target gain determined in step c) to generate a modified output corresponding to the pointer signal; wherein the predetermined angular velocity threshold information includes at least one accelerated angular velocity threshold and at least one decelerated angular velocity threshold corresponding to and less than the accelerated angular velocity threshold; and wherein step c) includes the sub-steps of
