Capability Detection
Confirm whether the browser exposes a haptic actuator.
Controller Vibration Test
Check whether your browser and gamepad expose rumble support. When supported, send weak or strong motor pulses directly from the local test panel.

Why Vibration May Show Unsupported
Vibration depends on browser, operating system, controller model, connection mode and driver behavior. A controller can vibrate in games while still not exposing a compatible haptic actuator to the browser.
DualSense adaptive trigger resistance is not controlled by the standard Gamepad API. This page checks browser-exposed rumble only.
Rumble Checks
Use vibration together with input checks to confirm both controls and haptics.
Weak Motor
Send a short low-intensity pulse when supported.
Strong Motor
Send a short high-intensity pulse when supported.
