Steam Controller


The Steam Controller is a game controller developed by Valve for use with personal computers running Steam on Windows, macOS, Linux, smartphones or SteamOS. The controller was designed not only for games developed for controller users, but also for games traditionally played with keyboard and mouse controls so that they can be played through the controller. It was released in November 2015 to support Valve's Steam Machine and discontinued in November 2019.

Features

The Steam Controller features two high-resolution clickable trackpads, and fourteen buttons, including face, shoulder, and undergrip buttons. The trackpads include haptic feedback, which can send tactile feedback to the player in reaction to events within the game; Chris Kohler of Wired described using the controller while playing Civilization V at a press event at Valve, and noted that as he used the trackpad to move the mouse cursor, electromagnets within the controller created audio and tactile feedback as if he were using a trackball. Although the controller is designed for the Steam Machine platform, it can also be used with Steam on existing PCs. The controller also included gyroscopic sensors to detect the relative orientation of the controller.
The controller is presently designed to be used within Steam's Big Picture mode; this enables the player to access detailed options for setting up the various features of the controller on a per-game basis including button/trackpad mapping and sensitivity as well as accessing other users' shared controller configuration to use themselves. The Steamworks API provides means for developers to provide more detailed settings for the Steam Controller when in Big Picture mode. Outside of Big Picture mode, the controller otherwise behaves as a standard two-stick controller, though Valve does plan on updating Steam to allow retaining the previously set Big Picture mode per-game settings.

Development

The original design of the controller was to include a touchscreen in the center of the unit. The touchscreen would have acted like a mousepad and allow players to perform actions that typically are not capable on controllers, operating directly with Steam or SteamOS and overlays touchscreen display onto the players' screens to allow manipulation of the game without diverting attention from the screen. However, at the January 2014 Steam Dev Days event, Valve revealed they have since dropped the touchscreen concept from the controller, rearranged existing face buttons to be more compatible with existing games.
Valve went through several iterations for a controller that would be able to mimic keyboard and mouse controls, using prototypes made with 3D printing to test ergonomics. Early versions of the controller design included a trackball embedded in the controller to simulate mouse functionality but opted eventually for trackpads to give more customization functionality to developers including the ability to simulate the motion of trackball by tracking a finger's motion on the trackpad. The trackpads and controller design were made to minimize the amount of contact that a player's thumbs would have on the trackpad when holding the unit. Unlike their current plans to have third-party hardware vendors manufacture Steam Machines, Valve plans to remain the sole manufacturer of the Steam Controller. Valve's Greg Coomer stated that this decision was based on achieving the best implementation of the Controller and Valve's vision for the device, noting that "we didn’t think that it was really going to be possible to outsource the design for manufacturing and the finishing of the controller in a way that would allow third parties to take from us an idea or a reference design and bring it to market soon enough". Valve did clarify that they will open up specifications for third-party controllers to be developed., Valve is working with Flex robotic assembly line in Buffalo Grove, Illinois to assemble the machines; jokingly, the machines have been given Aperture Science branding, the fictional company from Valve's Portal series.

Updates

Valve has pushed out updates that enable more customization and functionality to the Steam Controller. Valve has added improvements to the controller's capabilities based on public feedback following its launch, which include movement and aiming controls schemes using its internal gyroscope, the ability to trigger actions that enable cursor movement limited to certain regions on a UI, a quick-access popup for 16 commands that can act similar to hotkeys for keyboard-and-mouse games, cloud-based controller configuration saving, and support for non-Steam games that otherwise can be played through the Steam Overlay. Several updates were introduced in June 2016. One update enabled users to create actions using the Controller to switch between two or more different configurations on the fly. This update also enabled the ability to customize the motion-sensing controls to be used for virtual reality games. A second update in June 2016 enabled buttons to be "Activators" which can respond differently based on the type of input on the button, distinguishing between a single short tap, an extended hold, and a double-tap, for example. Activators can also be used to simulate the constant holding of a button with a single press, such as often used for the action of crouching in many first-person or third-person shooters.
Valve is planning on supporting similar controller customization features and user interfaces to other compatible controllers, and released the first such update in the Steam software for Sony's DualShock 4 controller in December 2016, and beta support for other controllers including Xbox One in January 2017. Support for the Nintendo Switch Pro Controller was added in May 2018. While other controllers can be used on Steam through basic operating system functionality, Steam's support will allow players to customize supported controllers through a similar interface offered for the Steam Controller. Further, developers do not have to be aware of the specific controller as the same Steam controller interface handles the translation to the specific hardware used by the player.
On March 23, 2016, Valve announced it would be publicly releasing computer aided design geometry for the Steam controller. The CAD geometry will be released under a Creative Commons license.
In May 2018, Valve updated the controller to enable its Bluetooth communications, allowing it to pair with mobile devices. This allows the controller to be used alongside the Steam Link app which replaced Steam Link hardware.

Release and reception

The Steam Controller was publicly released in November 2015, alongside the release of Steam Machines. By June 2016, over 500,000 had been sold and by October, nearly one million had sold, including the controllers bundled with the Steam Machines. In October 2016, Valve disclosed 27,000 controllers were in "daily active use". In September 2018, Valve disclosed new figures showing approximately 1.5 million Steam Controllers have connected to Steam, with about 14% of those having connected to Steam within the month the survey was performed. For comparison, the most popular controller used with Steam is the Xbox 360 controller, at around 27.2 million connections and 14% of those connected within the month of the survey.
Valve announced in November 2019 that it had discontinued further production of the controller and sold off its remaining inventory at a significantly reduced price.
