Abstract
A method of moving a plurality of appendages of an operator in contact with a touch surface including the steps of measuring a plurality of locations when the touch surface is touched by the plurality of appendages, moving the touch surface in a swirling motion by one or more actuators coupled with the touch surface, controlling a voltage on each of a plurality of electrodes disposed below the touch surface, controlling an electrostatic normal force acting on each of the appendages by adjusting the voltage applied to each of the plurality of appendages by each electrode lying beneath the appendage, synchronizing the electrostatic normal force generated by the voltage applied to each of the plurality of appendages with the swirling motion by basing a frequency of the swirling motion on the frequency of application of the electrostatic normal force.
