METHOD AND APPARATUS FOR TACTILELY RESPONSIVE USER INTERFACE

摘要

PROBLEM TO BE SOLVED: To provide an actuator having electrically-controlable tactile responsiveness.SOLUTION: There are provide a method and apparatus implementing a user interface device, such as a mouse or trackball, having electronically controllable tactile responsiveness which is flexibly programmable. The interface device includes at least two sets of wheels that move as the interface device is actuated. A servo motor 116 is attached to each of the at least two sets of wheels. A position encoder 118 is associated with each servo motor 116 and outputs position information to a controller 120.
