System and method for providing passive haptic feedback

摘要

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.

主权项

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.
