How it works and good to know
Reads input through the browser’s Gamepad API; for privacy, a gamepad appears only after you press a button. Standard-mapping gamepads are shown as a diagram, others by button number. Stick drift is judged from the maximum tilt during 3 seconds hands-off, and a recommended dead zone is calculated. Vibration works only in supporting browsers such as Chrome and Edge, and with supporting gamepads. If several are connected, you can choose which to view. Input is never sent anywhere.
