Page "Joystick" Paragraph 16

A distinct variation of an analog joystick is a positional gun, which works differently to a light gun.

Instead of using light sensors, a positional gun is essentially an analog joystick mounted in a fixed location that records the position of the gun to determine where the player is aiming on the screen.

It is often used for arcade gun games, with early examples including Sega's Sea Devil in 1972, Taito's Attack in 1976 and Cross Fire in 1977, and Nintendo's Battle Shark in 1978.
