Game controller

A game controller, gaming controller, or simply controller, is an input device or input/output device used with video games or entertainment systems to provide input to a video game. Input devices that have been classified as game controllers include keyboards, mouses, gamepads, and joysticks, as well as special purpose devices, such as steering wheels for driving games and light guns for shooting games. Controllers designs have evolved to include directional pads, multiple buttons, analog sticks, joysticks, motion detection, touch screens and a plethora of other features. A game controller is a device used with video games or entertainment systems to provide input to a video game, typically to control an object or character in the game. Controllers may be input devices that only provide input to the system or input/output devices that receive data from the system and produce a response (e.g., rumble or create sound). Controllers which are included with the purchase of a home console are considered as standard controllers, while those that are available to purchase from the console manufacturer or third-party offerings are considered peripheral controllers. 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. 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. Before the seventh generation of video game consoles, plugging in a controller into one of a console's controller ports was the primary means of using a game controller, although since then they have been replaced by wireless controllers, which do not require controller ports on the console but are battery-powered.
