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.
Claims32
An input device, comprising:
- a first module for detecting vibrations as the input device is moved across a surface;
- and
- a second module for storing data output from the first module.
A method of tracking a motion of an input device comprising:
- estimating a velocity of the input device based upon a first set of data and a second set of data;
- and
- positioning a display object based at least in part upon said velocity,
- wherein the first set of data is based at least in part upon a sensory value, and wherein the second set of data is based at least in part upon vibrations associated with the input device moving across a surface.

A computer readable medium storing computer executable instructions which, when executed by a computer, performs a process comprising:
- receiving a signal generated by a vibration sensor indicative of contact with a surface;
- and
- determining a speed of the input device based at least in part upon the signal.
A system comprising:
- an input device adapted to interact with a surface;
- a computing device adapted to receive a signal from the input device;
- and
- a graphical object adapted to respond to a command issued by the computing device,
- wherein the signal comprises a value that is based at least in part upon a vibration induced by the input device moving upon a surface.
