Abstract
A joystick controller for use with a home electronic video game produces electrical control signals in response to manipulation of a control stick. Within the controller housing a pair of light sources produce orthogonal light beams which are detected by respective light detectors to produce the control signals. A shutter, actuated by movement of the control stick, regulates the light falling onto the light detectors to produce control signals indicative of control stick positions.
