1. A device comprising:
- a manipulandum;
a haptic effect generator coupled to the manipulandum and operable to provide a first haptic profile associated with first mechanical configuration and a second haptic profile associated with a second mechanical configuration, wherein the haptic effect generator is operable to alter a surface of the manipulandum; and
an actuator in communication with the haptic effect generator and operable to switch the haptic effect generator between the first haptic profile and the second haptic profile by moving a follower from a first cam to a second cam, wherein the actuator comprises a core coupled to the follower and configured to position the follower based in part on a magnetic field output by one of a first coil associated with the first mechanical configuration or a second coil associated with the second mechanical configuration, wherein the first haptic profile comprises a first detent profile associated with the first cam and the second haptic profile comprises a second detent profile associated with the second cam.

Abstract
Systems and methods for low power consumption haptic feedback are described. In one described system, a device comprises a manipulandum and a haptic effect generator in communication with the manipulandum. The actuator is operable to provide a first haptic profile associated with a first mechanical configuration and a second haptic profile associated with a second mechanical configuration. The device also comprises an actuator in communication with the haptic effect generator, which is operable to switch the haptic effect generator between the first haptic profile and the second haptic profile.
