The most prominent elements of the Steam controller are its two circular trackpads. Driven by the player’s thumbs, each one has a high-resolution trackpad as its base. It is also clickable, allowing the entire surface to act as a button. The trackpads allow far higher fidelity input than has previously been possible with traditional handheld controllers. Steam gamers, who are used to the input associated with PCs, will appreciate that the Steam Controller’s resolution approaches that of a desktop mouse.
