Abstract:
There is provided an operating method of a capacitive finger navigation device including the steps of: calculating a touch coordinate according to a predetermined position coordinate and associated detected variation of each of a plurality of detecting cells when the associated detected variations of the detecting cells exceed a threshold; mapping the touch coordinate to a touch position associated with a touch surface; entering a relative motion mode when the touch position is in a first area; and entering an absolute coordinate mode when the touch position is in a second area.
