1. A device, comprising:

  • a manipulandum having a protrusion extending therefrom;

    a sensor having a stationary planar surface configured to measure at least one of a position or movement of the protrusion in contact therewith wherein the protrusion moves with respect to the stationary planar surface, the sensor configured to measure a force applied to the planar surface when the manipulandum is moved in a direction substantially perpendicular to the planar surface, wherein the sensor is configured to output a sensor signal associated with at least one of the sensed position or movement or force; and

    an actuator coupled to and spaced apart from the sensor, the actuator configured to receive a feedback signal associated with the sensor signal and generate haptic feedback based on the feedback signal.
