First Claim
Patent Images
1. A scrolling control method for a track input device, comprising:
- configuring a scrolling triggering area and a cursor area in a sensing area of the track input device;
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 of the sensing 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.
