This section includes controls operated by head movement.

Head operated mouse controllers use slight head movements to move the pointer across the screen or to select buttons on a keyboard. This is usually done using a reflective dot placed on your forehead, a laser pointer or wearing a cap or a pair of glasses. A switch might be used with the head operated mouse to give the equivalent of a mouse click, or alternatively software can be programmed to simulate a mouse click when the pointer stops moving.^1-2

Eye operated systems have a built in camera that detects where your eyes are looking, so you can highlight something on the screen simply by looking at it. To select the area you look at the object for a specified length of time or blink or press a switch to select the cell you are looking at.
