Abstract
A control method for a touchpad is provided. When a vibration unit is driven, the touchpad enters a touch function restriction mode so that the touchpad undergoes various different controls compared to the normal mode. This helps to avoid erroneous capacitive sensing caused by the driving of the vibration unit, preventing determinations in touch operations and avoiding the accidental triggering of commands or gestures. As a result, it reduces or minimizes the influences on user operations.
Claims21
A control method for a touchpad, wherein the touchpad has a main body and a vibration unit, and the control method comprises steps of:
- executing a touch function restriction mode when the vibration unit is driven to vibrate the main body;
- and
- terminating executing the touch function restriction mode when the touch function restriction mode continues until a specific condition is met.
