Analog stick


An analog stick, sometimes called a control stick or thumbstick, is an input device for a controller that is used for two-dimensional input. An analog stick is a variation of a joystick, consisting of a protrusion from the controller; input is based on the position of this protrusion in relation to the default "center" position. While digital sticks rely on single electrical connections for movement, analog sticks use continuous electrical activity running through potentiometers to measure the exact position of the stick within its full range of motion. The analog stick has greatly overtaken the D-pad in both prominence and usage in console video games.

Usage in video games

The initial prevalence of analog sticks was as peripherals for flight simulator games, to better reflect the subtleties of control required for such titles. It was during the fifth console generation that Nintendo announced it would integrate an analog stick into its iconic Nintendo 64 controller, a step which would pave the way for subsequent leading console manufacturers to follow suit.
An analog stick is often used to move some game object, usually the playable character. It may also be used to rotate the camera, usually around the character. The analog stick can serve a great variety of other functions, depending on the game. Today many analog sticks can also be pushed in like conventional face buttons of a controller, to allow for more functions. With the prevalence of analog sticks, the aforementioned limitations of the D-pad ceased to be an issue.

Dual analog sticks

Two analog sticks offer greater functionality than a single stick. On some modern game controllers, the left stick is positioned to the upper left of the D-pad while the right stick is positioned to the lower left of the face buttons. First-party controllers with this configuration include the Nintendo GameCube controller, Xbox controller, Xbox 360 controller, Xbox One controller, Nintendo Switch Joy-Con and Nintendo Switch Pro Controller.
Other controllers instead have the two analog sticks in a symmetrical configuration with a D-pad on the left thumb position and face buttons at the right thumb position, with analog sticks below and closer to the center on both sides. Sony's PlayStation-series analog controllers—the Dual Analog Controller, DualShock, DualShock 2, Sixaxis, DualShock 3, DualShock 4 and DualSense & mdash;all use this configuration, with the remainder of the controller layout closely resembling the original digital PlayStation controller. The Classic Controller for the Wii also uses this configuration. The original configuration of the Wii U GamePad controller had twin analog "Circle Pads" positioned symmetrically above the D-pad and face buttons, but was reconfigured to have twin clickable analog sticks in May 2012.
With genres such as action, adventure games, platforming, and shooting, the left stick normally controls the character's movement while the second stick controls the camera. The use of a second analog stick alleviated problems in many earlier platform games, in which the camera was notorious for bad positioning. The right stick not only allows for camera control in third-person games, but is almost essential for most modern first-person shooters such as Halo, where it controls the player's gaze and aim, as opposed to the left stick, which controls where the player moves. In Namco's Katamari Damacy and its sequels, both analog sticks are used at once to control the player's character.
Sony's PSP has been criticized for the lack of a second analog "nub" to accompany the left-hand one, a criticism that was later also leveled at Nintendo's 3DS. Nintendo has since released an add-on for the 3DS that adds, among other things, a second analog "circle pad". The follow-up to the PSP, the PlayStation Vita, features dual analog sticks. It is the first handheld game console to do so. The New Nintendo 3DS line of systems added a second analog controller, known as the "C-Stick" to the right side of the device.

History

Analog joysticks

The first consumer games console which had analog joysticks was the Prinztronic/Acetronic/Interton series, launched in 1976. This system was widely cloned throughout Europe and available under several brand names. The 2 sticks each used a pair of potentiometers, but were not self-centering.
In 1982, Atari released a controller with a potentiometer-based analog joystick for their Atari 5200 home console. However, its non-centering joystick design proved to be ungainly and unreliable, alienating many consumers at the time. During that same year, General Consumer Electronics introduced the Vectrex, a vector graphics based system which used a self-centering analog joystick.
In 1985, Sega's third-person rail shooter game Space Harrier, released for the arcades, introduced an analog flight stick for movement. It could register movement in any direction as well as measure the degree of push, which could move the player character at different speeds depending on how far the joystick is pushed in a certain direction.
Sega's analog Mission Stick was released for the Saturn console on September 29, 1995. On April 26, 1996, Sony released a potentiometer-based analog joystick for use in Flight-Simulation games. The Sony Dual Analog FlightStick featured twin analog sticks and was used in games such as Descent to provide a much greater degree of freedom than the typical digital joysticks of the day.

Analog thumbsticks

The NES max 1988, is the first instance of a thumb pad based joystick controller. The Quickshot Chimera 2, is another example of an early thumb stick controller available to the NES.
In 1989, the Japanese company Dempa released an analog thumbstick controller for the Sega Mega Drive console and Japanese computers called the XE-1 AP. This new controller included a thumb-operated control stick which allowed for varying levels of movement and near-360-degree control, translating into far more precise movements than were possible with a D-pad. It also distinguished itself by having the player control it with the thumb, similar to a D-pad, rather than gripping a handle. The controller was released twice, it is unsure if the early model contained the analog stick, as the Mega drive was unable to take in the inputs from an analog controller. It being much more lightly to be on the second release as it was to compete with the N64 and it also supported multiple hardware platforms.
popularized the thumbstick
Initially announced in late 1995, Nintendo released their Nintendo 64 controller on June 23, 1996, in Japan. The new controller included a thumb-operated control stick which, while a digital stick, still allowed for varying levels of movement and near-360-degree control, translating into far more precise movements than were possible with a D-pad.
On July 5, 1996, Sega released Nights into Dreams... for their Saturn console in Japan; bundled with it was the Saturn 3D control pad which featured an analog pad intended to give the player more fluid control over that game's flight-based gameplay. The analog pad used magnet-based Hall effect sensors, which was a unique implementation of the technology that was carried forward into the design of the Dreamcast controller as well. The Saturn's analog controller was previously mentioned in the June 1996 issue of Computer and Video Games magazine.
On April 25, 1997, Sony introduced the world's first dual stick controller for its game console, PlayStation. Based on the same potentiometer technology that was used in the larger Dual Analog Flightstick, the Sony Dual Analog Controller featured rumble, three modes of analog, and dual plastic concave thumbsticks.
On November 20, 1997, Sony released their third analog controller to the market: the DualShock. The controller featured similar twin analog sticks to the Dual Analog, although they featured convex rubber tips rather than concave plastic ones. Sony also removed the third analog mode and added two new buttons, L3 and R3, under the thumbsticks, which could be used by pressing down on the sticks.
In 1999, Sony's Ape Escape became the first video game in history to require the use of two analog sticks.
In the console generations that followed, many video game console controllers have included two analog sticks, with the exception of the Sega Dreamcast controller and Nintendo's Wii Remote controller. Other exceptions to this dual-stick rule are Sony's PlayStation Portable and Nintendo's 3DS handheld game consoles aside from the New 3DS, which both feature only a single small, flat sliding analog "nub". However, Sony's PlayStation Vita does have a dual analog stick configuration.
