Abstract
A scrolling control method for a track input device including a sensing area and a controller is disclosed. The scrolling control method includes configuring a scrolling triggering area and a cursor area in the sensing area, receiving a first track signal at the sensing area, determining whether a displacement quantity of the first track signal is greater than a triggering threshold value when the first track signal is received by the scrolling triggering area, and entering a scrolling mode and sending a scrolling signal when the displacement quantity of the first track signal is greater than the triggering threshold value.
