Steam Controller has hidden motion features
Player One writes "Although Valve always talked about the touchpads and buttons of the Steam Controller, it seems that it has some hidden features that only some users know about. While you can set your Controller to emulate a keyboard and mouse combo, there is a little hidden option that can allow you to aim by doing motions in the air. Of course, this won’t be accurate or sensitive enough to give you precise control, but it can be a great tool for fine-tuning your aim when you can’t get that 100% accuracy on the pad."
