Abstract
Systems and methods for providing haptic feedback in a user interface are disclosed. In one embodiment, an apparatus comprises a manipulandum, a rotor in communication with the manipulandum, an actuator in communication with the rotor, and a biasing element disposed between the manipulandum and the rotor. The actuator may be configured to vary a force on the rotor. The biasing element may be configured to store at least a portion of energy input to the apparatus when the actuator increases the force on the rotor, and to provide at least a portion of the stored energy to the manipulandum when the actuator decreases the force on the rotor, or when the manipulandum is released.
