1. A device comprising:
- a surface having a first channel comprisinga first plurality of surface features, the first plurality of surface features configured to provide a first haptic profile, anda second channel substantially parallel to the first channel and comprising a second plurality of surface features, the second plurality of surface features configured to provide a second haptic profile;
a follower configured to follow the first channel and the second channel; and
an actuator in communication with the follower and operable to move the follower between the first channel and the second channel, wherein the actuator comprises a member formed of shape memory alloy.

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.
