Which controllers are supported by the browser Gamepad API?

All standard HID-compliant controllers work including Xbox One/Series X|S, PlayStation DualShock 4 and DualSense 5, Nintendo Switch Pro Controller, and most third-party USB and Bluetooth gamepads. Connect via USB or Bluetooth and press any button to activate.

How does the trigger pressure gauge work?

Analog triggers (L2/R2 on PlayStation, LT/RT on Xbox) report continuous pressure values from 0.0 (released) to 1.0 (fully pressed). The pressure gauge visualizes this range in real-time so you can verify smooth, linear trigger response without dead zones.

Can I test controller vibration and rumble motors?

Yes! The rumble test uses the Gamepad Haptic Actuator API to pulse the left (heavy) and right (light) vibration motors at configurable intensities, letting you verify both motors are functional.

Gamepad & Controller Tester Browser Diagnostic API & Technical Specification

Formula representation used for accurate calculations:

MediaDevices API: navigator.mediaDevices.getUserMedia({ video: { width, height, frameRate }, audio: true }) Refresh Rate: requestAnimationFrame() frame count per 1-second window Gamepad API: navigator.getGamepads() polling axis/button state at 16.67ms intervals

Calculation Example: Webcam: 1920×1080 @ 30fps via getUserMedia constraint negotiation. Screen: 144Hz detected via 144 RAF callbacks per 1000ms window.
