Abstract:
A method and apparatus for determining the speed and/or position of an input device from vibrational signals is disclosed herein. In one embodiment, a response spectrum is generated as the input device moves across a surface. Amplitude and frequency data associated with the response spectrum is analyzed to determine the magnitude of the velocity.
