Abstract:
A method of smoothing the movement of a cursor controlled by an optical pointing apparatus includes the steps of sensing an image of a surface and generating a sensing signal by an optical pointing apparatus, continuously outputting a movement signal to control the movement of a cursor on a display by the sensing signal, and smoothing the continuously outputted movement signal at different levels according to the speed represented by the movement signal.
