Abstract: An electromagnetic actuator provides haptic feedback in a computing device. The electromagnetic actuator includes an actuator gap between the moveable actuator plate and the actuator. A gap sensor measures the actuation gap between the force plate and the actuator. The gap distance between the moveable actuator plate and the actuator may vary due to various environmental or user factors. The amount of haptic feedback provided to a user may be made consistent by adjusting the force exerted by the actuator on the actuator plate in response to measured variations in the gap distance.
