1. An input device, comprising:
- a central core having a first end coupled to a first lead, a second end coupled to a second lead, and a winding;
a manipulandum slidably coupled to the central core and comprising a third lead, the third lead configured to contact the winding;
a braking surface; and
an electromagnet configured to repel the braking surface to cause the braking surface to contact the manipulandum when the electromagnet is activated to cause a haptic effect.

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.

7. A method comprising:
-
receiving a sensor signal indicating a movement of a manipulandum slidably coupled to a central core; transmitting an actuator signal to an actuator, the actuator comprising an electromagnet; and repelling a braking surface by energizing an electromagnet to cause the braking surface to contact the manipulandum to output a haptic effect.

8. A non-transitory computer-readable medium comprising program code, the program code comprising:
-
program code for receiving a sensor signal indicating a movement of a manipulandum slidably coupled to a central core; program code for transmitting an actuator signal to an actuator, the actuator comprising an electromagnet; and program code for causing an electromagnet to repel a braking surface to the braking surface to contact the manipulandum to output a haptic effect.
