Abstract
A computer input device includes, in one embodiment, at least two accelerometers, at least two gyroscopes, and a processor within a housing. Signals from the accelerometers and the gyroscopes are utilized to determine the relative motion of the computer input device.
Claims22
A computer input device, comprising:
- a housing for movement over a substantially two-dimensional surface;
- a sensor unit, disposed within the housing, comprising at least two accelerometers and at least two gyroscopes;
- and
- a processor for determining relative motion of the computer input device utilizing signals from the accelerometers and the gyroscopes.
