1. A tactile feedback mouse, comprising:

  • a sensor configured to detect a movement of the mouse in a planar workspace and configured to output sensor signals representative of the movement; and

    a rotary actuator configured to receive a signal based on the sensor signals and output a haptic force based on the received signal, the rotary actuator having a shaft and an inertial mass coupled to the shaft, the rotary actuator configured to move the inertial mass approximately linearly by rotating the inertial mass bi-directionally a fraction of a full revolution about the shaft, the haptic force being generated by oscillating the inertial mass at an assignable frequency and magnitude.
