Abstract

A computer mouse includes a handheld casing and a motion detector coupled to the casing to detect movement of the casing. The computer mouse also includes a processor housed in the casing, the processor being in data communication with the motion detector to receive output of the motion detector. The processor includes programming to generate binary output signals from the output of the motion detector while not directly incorporating at least some respective motion detector output corresponding to inadvertent movements of the casing. The amount of movement considered inadvertent is adjustable by a user.

Claims

1. A computer mouse, comprising:

a handheld casing;

a motion detector coupled to said casing to detect movement of said casing;

a processor housed in said casing, said processor being in data communication with said motion detector to receive output of said motion detector; and

programming in said processor to generate smoothed binary output signals from said output of said motion detector.

2. The computer mouse of claim 1, wherein said programming in said processor uses a high pass filter and a low pass filter to smooth motion detector output corresponding to inadvertent casing movements in generating smoothed binary output signals.

3. The computer mouse of claim 2, further comprising an input in data communication with said processor to adjust said high pass filter and said low pass filter.
