A pointing device is any computer hardware component (specifically human interface device) that allows a user to input spatial (ie, 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 - point, click, 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 the screen by movements of the mouse pointer (or cursor) and other visual changes. Wikipedia does not have an article with this exact name. ...

3D Pointing Devices

PhaseSpace produces a 3D pointing device consisting of multiple linear detectors triangulating the position of a light source. This provides a spatial resolution of 3,600 x 3,600 at 480 frames per second. By modulating the Light Source, multiple sources can be identified and tracked simultaneously. This can be used for Virtual Reality, Augmented reality, Training and other applications where a three dimensional input device is needed, or the interface is designed to be by pointing and gesturing rather than operating on a button or joystick.
