pointing device definition hardware
Any hardware component that allows a user to input spatial data to a computer. CAD
systems and Graphical User Interfaces
(GUI) allow the user to control and provide data to the computer using physical "gestures" - point
, and drag
- typically by moving a hand-held mouse
across the surface of the physical desktop and activating switches on the mouse. Movements of the pointing device are echoed on a graphical representation of a desktop on the screen by movements of the mouse pointer and other visual changes.
While the most common pointing device by far is a mouse, other kinds include tracker ball
, lightpen, various kinds of digitising tablets which use a stylus, and even a special "data glove
" that translates the user's movements to computer gestures.
