A light gun is a
pointing device for
computers and a
control device for
arcade and
video games. The first light guns appeared in the 1930s, following the development of light-sensing
vacuum tubes. It was not long before the technology began appearing in
arcade shooting games, beginning with the
Seeburg Ray-O-Lite in
1936. These early light gun games, like modern
laser tag, used small targets (usually moving) onto which a light-sensing tube was mounted; the player used a gun (usually a
rifle) that emitted a beam of light when the
trigger was pulled. If the beam struck the target, a "hit" was scored. Modern screen-based light guns work on the opposite principle - the sensor is built into the gun itself, and the on-screen target(s) emit light rather than the gun. The first light gun of this type was used on the
MIT Whirlwind computer.

A handheld directional light signaling device which emits a brilliant narrow beam of white, green, or red light as selected by the tower controller. The color and type of light transmitted can be used to approve or disapprove anticipated pilot actions where radio communication is not available. The light gun is used for controlling traffic operating in the vicinity of the airport and on the airport movement area.
