The joystick has a normally central position; movement of the joystick to a non-central position indicates the directional vector along which movement of the display cursor, such as a cursor of a video cathode-ray tube display, is to proceed. The farther the joystick is from the central position, the faster the cursor moves along the indicated directional vector. | |
