In the third and final of Valve's living room announcements is the unveiling of the Steam Controller. With the previously announced SteamOS and Steam Machines a new type of controller is needed to bridge the gap between PC and console interfaces: The Steam controller. The Steam controller features dual circular trackpads on each side of the controller. These can act both like a mouse or like thumbsticks featured in more traditional controllers. The gamepad allows RTS, 4X, point-and-click and other cursor-driven games to be played from a sofa. The trackpads also feature high precision haptic feedback that can deliver a wide variety of forces and vibrations to the user's thumbs. They can even function as small speakers and produce sound. Aside from these trackpads the controller features four shoulder buttons, two read triggers, three buttons along the bottom of the controller and four buttons labelled X, Y, A & B surrounding a central touch screen. The touchscreen allows the further functions to be programmed in for games that require more buttons and inputs than the controller already has, allowing the controller to theoretically work with pretty much any game. When using the touch screen Steam will overlay the image from it to the game's main screen so that players do not have to take their eyes off the TV. Players can make their own configurations for older games not designed with the Steam controller in mind and share them with others. An example configuration for Portal 2 is shown bellow. For those hoping to participate in the Steam hardware beta announced yesterday the controller being sent out for those are going to be slightly different to the eventual release version; they will be wired and have four buttons in the centre instead of a touchscreen, but lucky participants will still be getting their hands on these fancy touchpads before everyone else. If you want to try getting your hands on it make sure to check quest page to see what you have to do to be eligible and good luck!
