ABSTRACT:
A joystick for moving a cursor on a display screen uses an infrared transmitter (34) radiating into a transparent handle (14). As the handle is moved by an operator, infra-red light is directed to one of four optical detectors (31) covering up, down, left and right directions respectively. The device can also detect movement at 45 degrees to any of these directions since light is then directed to two detectors (31). A further four optical detectors (31a) are provided, each arranged adjacent one of the first four detectors (31), so that further movement of the handle in the same direction can be detected. An additional optical detector (37) is arranged to detect downward movement of the handle (14) against a spring (24). The handle is translatably mounted, rather than pivotally mounted as in a stand joystick.
