  • Patent number: 6262712
    Abstract: An apparatus and a method for controlling a feedback force applied by a joystick to a user gripping the control handle of the joystick. In the preferred embodiment, a light path between an infrared light source and a light sensor is interrupted by a user gripping the handle of a joystick. The output signal from the light sensor is employed by a processor to control the feedback force. When based upon the output signal, the processor determines that the user has just gripped the control handle, the processor enables the feedback force to increase slowly, over a sufficiently long time to enable the user to firmly grip the control handle before the feedback force becomes very strong. The processor immediately disables generation of the feedback force as soon as the user releases the control handle.
