Abstract
A method of controlling an electronic device having a touch-sensitive display includes imparting, by an actuator, a force on the touch-sensitive display to provide tactile feedback, determining the force applied by the actuator on the touch-sensitive display, and adjusting a subsequent force imparted by the actuator based on the determined force.
Claims13
A method of controlling an electronic device having a touch-sensitive display, the method comprising:
- imparting, by an actuator, a force on the touch-sensitive display to provide tactile feedback;
- determining, based on signals from an accelerometer and a force sensor, the force imparted by the actuator on the touch-sensitive display by subtracting a force determined utilizing the force sensor from a force determined utilizing the accelerometer;
- comparing the determined force to a target force;
- and
- adjusting a subsequent force imparted by the actuator based on the comparison.
2 more elements
An electronic device comprising:
- a base;
- a touch-sensitive display moveable relative to the base;
- an actuator arranged to impart a force on the touch-sensitive display;
- a force sensor;
- an accelerometer;
- and
- a processor operably coupled to the touch-sensitive display, the actuator and the accelerometer, the processor configured to
- determine, based on signals from the accelerometer and the force sensor, the force imparted by the actuator on the touch-sensitive display by subtracting a force determined utilizing the force sensor from a force determined utilizing the accelerometer;
- compare the determined force to a target force;
- and
- adjust a subsequent force imparted by the actuator based on the comparison.
