ELECTRONIC DEVICE INCLUDING TACTILE TOUCH-SENSITIVE DISPLAY AND METHOD OF CONTROLLING SAME
First Claim
1. A method of controlling an electronic device having a touch-sensitive display, the method comprising:
- 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;
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.

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.
