ABSTRACT:
A system and method for emulating a mouse input device with a touchpad input device having a drag switch and touch device in which the direction of movement of the touch device across the touchpad surface is determined, a display cursor is caused to move in the same relative direction as the direction determined by the touch device, and the cursor movement is continued in that same relative direction either in or out of a drag mode, even after the touch device stops moving so as to allow the cursor to be moved a greater distance than the touch device.
