LIGHT PEN

A Light Pen is a pointing device shaped like a pen and is connected to a Video Display Unit (VDU). The tip of the light pen contains a light-sensitive element that, when placed against the screen, detects the light from the screen enabling the computer to identify the location of the pen on the screen.
