Google’s Stadia game-streaming platform works on a number of screens, but Google wants to give you a controller to take on all of these displays. Sure, you can use your regular keyboard and mouse or a third-party controller but Google has also opted to showcasing their own Stadia controller.

It’s not just a pretty look, Google’s controller connects to WiFi directly rather than your device to reduce latency in input. We didn’t get too many details on exactly how this works, so hopefully we’ll get a more technical breakdown soon.
