Abstract
A method and apparatus of actuator control mechanisms for haptic effects are disclosed. The apparatus can include an actuator and a controller for controlling a haptic cell. Depending on the type of haptic effect desired, as well as the damping characteristics of the system, the controller can generate a kick-in pulse followed by a main pulse to create an increased acceleration response, and/or a breaking pulse to provide a damping effect for a short mechanical type of haptic effect.
