ELECTRONIC DEVICE INCLUDING SENSOR DRIVEN HAPTIC ACTUATOR AND RELATED METHODS

Abstract:

An electronic device may include a haptic actuator that includes a field member including at least one permanent magnet, and at least one coil configured to cause relative movement with the field member. The electronic device may also include at least one inductance sensor configured to sense relative movement between the at least one coil and field member and a processor configured to drive the at least one coil based upon the at least one inductance sensor.
