Joystick
The joystick is an input device commonly used to control video games.
Joysticks consist of a base and a stick that can be moved in any direction. The stick can be moved slowly or quickly and in different amounts.
Light Pen
A light pen is a computer input device that looks like a pen. The tip
of the light pen contains a light-sensitive detector that enables the user to
point to or select objects on the display screen. It is not compatible
with LCD screens, so it is not in use today. It also helps you draw on the
screen if needed.
