A joystick is a computer input device that is particularly useful for playing computer games. It consists of a handle that can be pointed in various directions. The computer can sense the direction in which the joystick is pointed, allowing it to control the movements of objects displayed on the computer screen.
A pointing device is an input device that allows users to manipulate a cursor in a graphical user interface. The most common example is a mouse, but other types include trackballs, graphics tablets, joysticks, and various pen-type devices.
