Abstract
Systems and methods for providing passive haptic feedback are described. Embodiments of the present invention comprise an actuator for bringing a manipulandum and braking surface into contact and thereby providing a resistance. The manipulandum includes scroll wheels, scroll drums, linear sliders and similar user input devices. The actuator may be, for example, electromagnetic or piezo-electric. An embodiment of the present invention may include a processor in communication with the actuator for providing the haptic effects.
