Game controller

A game controller is a device used with games or entertainment systems to provide input to a video game, typically to control an object or character in the game. A controller is usually connected to a game console or computer by means of a wire or cord, although, since the mid-2000s, wireless controllers have become widespread. Input devices that have been classified as game controllers include keyboards, mouses, gamepads, joysticks, etc. Special purpose devices, such as steering wheels for driving games and light guns for shooting games, are also game controllers.

Game controllers have been designed and improved over the years to be as user friendly as possible. The Microsoft Xbox controller, with its shoulder triggers that mimic actual triggers such as those found on guns, has become popular for shooting games. Some controllers are designed to be deliberately best for one type of game, such as steering wheels for driving games, or dance pads for dancing games.

One of the first video game controllers was a simple dial and single button, used to control the game Tennis for Two. Controllers have since evolved to include directional pads, multiple buttons, analog sticks, joysticks, motion detection, touch screens and a plethora of other features.

A light gun is a peripheral used to "shoot" targets on a screen. They usually roughly resemble firearms or ray guns. Their use is normally limited to rail shooters, or shooting gallery games like Duck Hunt and those which came with the Shooting Gallery light gun. A rare example of a non-rail first person shooter game is Taito's 1992 video game Gun Buster, a first-person shooter that used a joystick to move and a light gun to aim. Though light guns have been used in earlier arcade games such as Sega's Periscope in 1966 and Missile in 1969, the first home console light gun was released for the Magnavox Odyssey in 1972; later on, Nintendo would include one standard on their Famicom and NES, called the NES Zapper. Nintendo has also released a "shell" in the style of a light gun for the more recent Wii Remote called the Wii Zapper which comes bundled with the game Link's Crossbow Training.
