JOYSTICK

Joystick is an input device used for games, computer aided designs or simulations. It is like a lever that moves in all directions and controls the movement of a pointer or some  other display symbol. A joystick is similar to a mouse, except that with a mouse the cursor stops moving as soon as you stop moving the mouse. With a joystick, the pointer continues moving in the direction the joystick is pointing. To stop  the pointer, you must return the joystick ti its neutral position. Most joysticks include two buttons called triggers.
