Abstract
According to some embodiments, an electronic device can include a processor and a haptic feedback system. The haptic feedback system can include a mass that is coupled to a magnetic element and variable magnetic elements capable of establishing a magnetic field in communication with the magnetic element that varies in accordance with the processor receiving a signal that indicates that a touch event is detected at a touch sensitive layer, where the magnetic field causes displacement of the magnetic element. The haptic feedback system can further include a magnetic field sensor in communication with the processor, where the magnetic field sensor is capable of (i) detecting a change in the magnetic field that is induced by the displacement of the magnetic element, and (ii) providing a detection signal to the processor that corresponds to a current position of the mass that is coupled to the magnetic element.
