Pointing Devices
A pointing device is any human interface device that allows a user to input spatial data to a computer. In the case of mice and touch screens, this is usually achieved by detecting movement across a physical surface. Analog devices, such as 3D mice, joysticks, or pointing sticks, function by reporting their angle of deflection. Movements of the pointing device are echoed on the screen by movements of the pointer, creating a simple, intuitive way to navigate a computer's GUI.

Famous quotes containing the words pointing and/or devices:
“And they heaved a mighty breath, every soul on board but me,
As they saw her nose again pointing handsome out to sea;
But all that I could think of, in the darkness and the cold,
Was just that I was leaving home and my folks were growing old.”
—Robert Louis Stevenson (1850–1894)
“The gods being always close to men perceive those who afflict others with unjust devices and do not fear the wrath of heaven.”
—Hesiod (c. 8th century B.C.)
