Abstract
A variable resistance joystick (20) configured for computer control is provided. A stepper motor (34) turns threaded screws (30) to move a system of springs (26) up and down on the joystick thus varying the lever arm on which the springs impart force. Thus computer commands (113) to the stepper motor may change the force required by a user to move the joystick. A similar system controls the resistance to movement of a button (108) in the joystick handle (42).
