Pointing device
A
pointing device
is an
input interface
(specifically a
human interface device
) that allows a
user
to input
spatial
(i.e., continuous and
multi-dimensional
) 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
by moving a hand-held
mouse
or similar device across the surface of the physical desktop and activating switches on the mouse. Movements of the pointing device are echoed on the screen by movements of the
pointer
(or
cursor
) and other visual changes. Common gestures are
point and click
and
drag and drop
.
