| | Pointing device - Wikipedia, the free encyclopedia |
 | | Movements of the pointing device are echoed on the screen by movements of the mouse pointer (or cursor) and other visual changes. |
 | | While the most common pointing device by far is the mouse, other kinds include trackball, touchpad, pointing stick, lightpen, joystick, head pointer, eye tracking devices, various kinds of digitizing tablets which use a stylus, and even a special "data glove" that translates the user's movements to computer gestures. |
 | | Pointing device can also refer to a special "stick" (sometimes telescopic, to reduce the length when not in use), or a lamp with a narrow light beam that is pointed at a map, flboard, slide screen, movie screen, etc.; sometimes the light is in the form of an arrow. |
