Along with the hardware specifications for the Steam Machine, Valve has developed a new game controller named the Steam Controller. The controller is 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 features two high-resolution clickable trackpads (replacing the typical thumbsticks on modern console controllers), and sixteen 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.
