ABSTRACT:
A self-adjusting digital filter for smoothing computer mouse movement is disclosed. In one embodiment, a user-selectable inertial constant is applied to all types of mouse movements regardless of whether the movement is fast or slow and corrected mouse position data, or coordinates, are computed using the current actual mouse coordinates and the previous corrected mouse coordinates as adjusted by the inertial constant. In an alternative embodiment, a speed sensitive inertial constant, the value of which is dependent upon the values of a user-selectable speed sensitivity constant, the inertial constant, and the speed of the mouse movement, is substituted for the inertial constant such that the amount of filtering that occurs is at least partially dependent on the speed of mouse movement.
