Light gun

[4] Sega's 1969 game Missile features electronic sound and a moving film strip to represent the targets on a projection screen,[5] and its 1972 game Killer Shark features a mounted light gun with targets whose movement and reactions are displayed using back image projection onto a screen.

[6] Nintendo released the Beam Gun in 1970 and the Laser Clay Shooting System in 1973,[7] followed in 1974 by the arcade game Wild Gunman, which uses film projection to display the target on the screen.

[10] The first detection method, used by the NES Zapper, involves drawing each target sequentially in white light after the screen blacks out.

The positional gun is permanently mounted on a swivel on the cabinet, as an analog joystick for aiming crosshairs onscreen.

Early examples of a positional gun include Sega's Sea Devil in 1972,[21] Taito's Attack in 1976,[22] and Cross Fire in 1977,[23] and Nintendo's Battle Shark in 1978.
