Valve has released a video demonstrating its Steam Controller, a handheld gaming controller that will eventually be compatible with many Steam games, including popular titles like Portal, Counterstrike and Team Fortress.
The Steam Controller includes a touch screen in the center of the device with a pair of trackpads around the outside using "super-precise" haptic feedback and "dual linear resonant actuators" to deliver a range of force and vibration feedback sensations.The Steam Controller is designed to work with all the games on Steam: past, present, and future. Even the older titles in the catalog and the ones which were not built with controller support. (We've fooled those older games into thinking they're being played with a keyboard and mouse, but we've designed a gamepad that's nothing like either one of those devices.) We think you'll agree that we're onto something with the Steam Controller
The Steam Controller is currently in beta and is designed to work primarily with the Steam Machine set-top box. It will also work with any PC version of Steam, including Steam for Mac.
