ABSTRACT:
A joystick converter apparatus for use with computer keyboard arrow key arrays. A control rod includes four actuators which are structured and configured to interface with the UP, DOWN, RIGHT and LEFT arrow keys in an arrow key array. Two of the actuators are detachably coupled to two of the arrow keys, while the other two branches are positioned above and spaced apart from the other two arrow keys. Tilting or rocking the control rod in a desired direction provides corresponding cursor movement or directional control in computer programs.
