A game controller is an input device used to control a video game. A controller is typically connected to a video game
console or a personal computer. A game controller can be a keyboard, mouse, gamepad, joystick, paddle,
or any other device designed for gaming that can receive input. Special purpose devices, such as steering wheels for driving games and light guns for shooting games,
may also exist for a platform. Some devices, such as keyboards and mice, are actually generic input devices and their use is not
strictly limited to that of a game controller.
A game controller can be used to govern the movement or actions of an entity in a
video or computer game. The type of element
controlled depends upon the game, but a typical element controlled would be the player
character's actions and movements.
Types of game controller
Gamepad
-
A gamepad, also known as a joypad, is the most common kind of game controller, held with both hands where the thumbs are used
to provide input and can have anywhere from a couple of buttons to a dozen or more, combined with multiple omnidirectional
control sticks. Gamepads generally feature a set of action buttons handled with the right thumb and a direction controller
handled with the left. These let the player control the game element movements in up to three dimensions, with many buttons to
perform quick actions. Due to the ease of use and precision of gamepads, they have spread from traditional consoles where they
originated to computers as a common input device.
Most modern game controllers are a variation of a standard gamepad. Some common additions to the standard pad include shoulder
buttons placed along the edges of the pad, centrally placed buttons labeled start, select, and mode, and an
internal motor to provide force feedback.
Gamepads are the primary means of input on nearly all modern video game consoles.
Gamepads are also available for personal computers, but few computer games support
gamepads, preferring the more conventional keyboards and mice. However, most console emulators support gamepads.
Paddle
-
A paddle is a controller that features a round wheel and one or more fire buttons. The wheel is used to typically control
movement of the player or an object along one axis of the video screen. Paddle controllers were the first analog controllers;
they died out when "paddle and ball" type games fell out of favor. A variation on the Paddle, the Atari
driving controller appeared on the Atari 2600. Designed specifically for the game
Indy 500, It was almost identical in operation and design to the regular paddle
controller. However, its wheel can be continuously rotated in either direction, and it was missing the extra paddle included on
the previous model. Unlike a spinner, friction prevented the wheel from gaining momentum.
Trackball
-
A trackball is basically an upside-down mouse that is manipulated with the palm of one's hand. It has the advantage of not
requiring a lot of desktop space, and that it is as fast as one can roll the ball on it. This is faster than one can move a mouse
due to space not being an issue.
Notable uses of a Trackball as a gaming controller would be games such as Centipede, Marble Madness,Golden Tee and Sonic Arcade.
Joystick
-
This joystick is a computer peripheral that consists of a handheld stick that can be
tilted around either of two axes and (sometimes) twisted around a third. The joystick is often used for flight simulators. HOTAS controllers, composed of a joystick and
throttle quadrant (see below) are a popular combination for flight simulation among its most fanatic devotees.
Arcade style Joystick
This device can also be a home version of the kind used in the arcade, or for use on emulators. It features a shaft that has a
sphere-like handle that is grasped, and one or more buttons for in game actions. Generally the layout has the joystick on the
left, and the buttons on the right. There are instances when this is reversed, or the joystick is in the center with button on
both sides.
Throttle quadrant
A throttle quadrant, as the name indicates, is a set of one or more levers that are most often used to simulate throttles or
other similar controls in a real vehicle, particularly an aircraft. Throttle quadrants are most popular in conjunction with
joysticks or yokes used in flight simulation.
Steering wheel
The steering wheel, essentially a larger version of a paddle, is used for
racing simulators such as Live for Speed,
Grand Prix Legends, GTR2, and Richard Burns Rally. Many
are force feedback (see Force Feedback Wheel), designed to give the same feedback as you would
driving a real car, but the realism of this depends on the game. They usually come with pedals to control the gas and brake.
Shifting is taken care of with either paddles, a simple shifter which is moved forward or back to change gears, or a shifter
which mimics that of real vehicles, which may use a clutch. Most wheels turn only 200 to 270 degrees lock-to-lock, but some
models, such as the Logitech Driving Force Pro and
Logitech G25, can turn 900 degrees, or 2.5 turns lock-to-lock.
The Namco Jogcon paddle was available for the
PlayStation game R4: Ridge Racer Type 4. Unlike "real" video game steering
wheels, the Jogcon was designed to fit in the player's hand. Its much smaller wheel (diameter roughly similar to a
soda can's) resembles the jog-and-shuttle control wheel used on some VCRs.
Nintendo announced at E3 that they would be producing a Steering wheel, titled the WiiWheel. It will come bundled with Mario
Kart wii edition (Tentative Title). The WiiWheel dosen't have a stand so users will have to place back to centre by
themselves.
Yoke
A yoke is very similar to a steering wheel except that it resembles the control yoke found on many aircraft and has two axes
of movement: not only rotational movement about the shaft of the yoke, but also a forward-and-backward axis equivalent to that of
pitch control on the yoke of an aircraft. Some yokes have additional controls attached directly to the yoke for simulation of
aircraft functions such as radio push-to-talk buttons. Yokes, like throttle quadrants and pedals, are popular with serious
flight-simulation enthusiasts.
Pedals
Pedals may be used for driving simulations or flight simulations. In the former case, an asymmetric set of pedals can simulate
accelerator, brake, and clutch pedals in a real automobile. In the latter case, a symmetric set of pedals simulates rudder
controls and toe brakes in an aircraft.
Keyboard, mouse and mousepad
-
The
WASD keyboard setup is used widely
The keyboard and mouse are typical input devices for a personal computer and are currently the main game controllers for computer games. The keyboard and mouse with the aid of the mousepad achieve greater speed, comfort and accuracy for the gamer. Some video game consoles also have the
ability to function with a keyboard and a mouse. The computer keyboard is modeled after the typewriter keyboard and was designed for the input of written text. A mouse is a handheld pointing device used in addition to the keyboard. For games, the keyboard typically controls movement of
the character while the mouse is used to control the game camera or used for aiming.
The numeric keypad found on the keyboard is also used as a game controller and
can be found on a number of separate devices, most notably early consoles, usually attached to a joystick or a paddle. The keypad
is a small grid of keys with at least the digits 0-9.
Light gun
-
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 shooter or shooting gallery games like those that came with the
"Shooting Gallery" light gun. The first home console light gun was released on the
Magnavox Odyssey; later on, Nintendo would include one standard on their Famicom and NES. Nintendo will also release a "shell" in the style
of a light gun for the Wii Remote.
Touch screen
Nintendo DS Touch screen (bottom)
-
A touch screen is an input device that allows the user to interact with the computer by touching the display screen. It was
first used on a dedicated console with the Tiger game.com. Nintendo popularized it for use in video games with the Nintendo
DS; other systems including the Tapwave Zodiac as well as the vast majority of
PDAs have also included this feature.
Modern touch screens use a thin, durable, transparent plastic sheet overlayed onto the glass screen. The location of a touch
is calculated from the capacitance for the X and Y axes, which varies based upon where the sheet is touched.
RTS, and Programmable PC Controllers
There are a few specialized controllers that are specifically used for RTS games
and some arcade type games. These controllers can be programmed to allow the emulation of keys, and macros in some cases. They
were developed because some of these games require a keyboard to play, and some players find this to be awkward for such a task.

Others
- Train controls: At a smaller scale, other hardware such as train controls (available after Microsoft Train Simulator was released), pinball controllers and multi-button consoles for
strategy games were released in the past, but their popularity was limited to hardcore fans of the genre.
- Dance pads, essentially a grid of flat pressure sensitive gamepad buttons set on a mat
meant to be stepped on, have seen niche success with the popularity of rhythm games like Dance Dance Revolution and Pump it Up. The dance
pad was first introduced on the Atari 2600, called the "Exus Foot Craz" pad. Nintendo later purchased the technology from Bandai
and used it on their "Power Pad", for the Famicom and NES.
- Buzzers: A recent example of specialized, while very simple, game controllers, is the four large "buzzers" (round buttons)
supplied with the PlayStation 2 quiz show game series Buzz! (2005, 2006); both game and controllers clearly being inspired by the television show genre.
- Wii Remote: Nintendo's Wii system utilizes a new kind of
controller, called the Wii Remote. It uses accelerometers to detect its approximate orientation and acceleration and a built-in camera so it can be
used as a pointing device.
- NeGcon: is a unique controller for racing games on the PlayStation. Physically it resembles a
gamepad, but its left and right halves twist relative to each other, making it a variation of the paddle controller.
- Microphone: A few games have made successes in using a headset or microphone as a
secondary controller, such as Hey You, Pikachu! and the SOCOM: U.S. Navy SEALs series. The use of these microphones allowed players to issue commands to
the game, controlling teammates (as in SOCOM) and other AI characters (Pikachu).
- Steel Batallion for the XBOX was bundled with a full
dashboard, with 2 joysticks and over 30 buttons, in an attempt to make it feel like an actual mecha simulator.
- Fishing rod: the first fishing rod controller appeared as an accessory for the Sega
Dreamcast video console for playing SEGA Marine Fishing. Later other games for
Playstation console use also a similar controllers.
- Floating Interactive Display: since 2003[1] two companies, IO2Technology from the US and Fogscreen from Finland have
developed Minority Report style interactive floating
interfaces which display an image projected in mid-air but can be interacted with by finger similar to a touch screen. The
IO2Technology version is called the Heliosdisplay.
- PCGamerBike similar to a pair of pedals removed from an exercise bike, then set down in
front of a chair & used to precisely control game characters instead.
- Optical motion tracking systems such as TrackIR and Freetrack use a video camera to track an infrared illuminated or
emissive headpiece. Small head movements are tracked and then translated into much larger virtual in-game movements, allowing
hands-free view control and improved immersiveness.
- Instrument panels are simulated aircraft instrument panels, either generic or
specific to a real aircraft, that are used in place of the keyboard to send commands to a flight simulation program. Some of
these are far more expensive than all the rest of a computer system combined. The panels usually only simulate switches, buttons,
and controls, rather than output instrument displays.
Longevity of hardware
An Xbox 360 Wireless Controller
Given the number of mobile and soft rubber parts in controllers it can be expected that after extensive use, some of the
buttons will become eventually less responsive due to the softening of the rubber parts that connect the hard exterior button to
the integrated circuit. Evidence of this is clearly visible in the video game kiosks in stores. Even the plastic outer casings of
joysticks and wheels might crack if used too violently. This becomes more of an issue with cheaper third-party controllers.
Button mashing and joystick wobbling were responsible for countless broken
controllers until the mid of the 16-bit era, when
such games became progressively out of fashion.
Even better built joypads, able to endure mechanical wear for years, can be defeated by the development of games which require
more buttons or functions, or changes in the interfaces used, rendering them obsolete. For example, the increasing number of axes
and buttons demanded by computer flight simulator titles and the disuse of the PC gameport interface have left many working PC
controllers unusable. The end of a game console generation generally brings obsolescence for both a console and its
controllers.
Health concerns
Since the controller is the most common way of interacting with a game, it has to be ergonomically designed to feel comfortable to most of their potential userbase to avoid injuries such as the
ones in the RSI group or CTS.
Most controllers these days are designed with the relaxed position of the hands in mind, which gave origin to the "pronged"
design that reduced the soreness and cramping after extended use with older pads such as the NES or the Sega Master System.
Also, Nintendo fingers was a term coined in the early 90s after video game players had their thumbs badly burnt and
even developed blisters due to the hardness of the buttons. A more common, less dangerous
phenomenon sometimes known as a Nintendo cramp means the strain felt on the thumbs and the palm below. This tends to occur
mostly when using particularly small controllers. The latter may in fact occur on any finger or the hand if it is kept in a
prepared "arched" position for a long time, and is much less dangerous than Nintendo Fingers.
Currently, there are controller gloves available for the Wii Remote, Xbox 360 controllers, and SIXAXIS controllers in stores
to comfort players' hands.
