Abstract
A method of controlling an electronic device having a touch-sensitive display includes determining a first value representative of force applied by an actuator to a touch-sensitive input device of an electronic device, controlling the actuator to modulate the force on the touch-sensitive input device for providing tactile feedback, determining a second value representative of force applied by the actuator to the touch-sensitive input device, and adjusting control of the actuator to adjust a subsequent force applied by the actuator based on a difference between the first value and the second value.
