Help — Gamepad Test

Connect your gamepad, joystick, or wheel via USB or Bluetooth. Browsers only expose the device after you press a button on it (security requirement). Once detected, the controller appears as a pill in the top toolbar.

Modes:

• Visualizer — schematic gamepad with hit-heatmap (each button color-grades blue→green→cyan→amber→red as you press it more), analog axes, analog triggers, and a full button grid. Labels follow the active label scheme (Xbox / PlayStation / Nintendo / Numeric — cycle via the A/B button in settings).

• Stick gamut — rotate each stick in a full circle. The canvas draws all positions visited; outer ring = full deflection, inner ring = current deadzone. Octant coverage tells you whether the stick can reach every direction.

• Vibration — test the weak (high-freq) and strong (low-freq) motors independently or together. Magnitude (0–1) and duration (100–3000 ms) are configurable. Not all controllers expose vibrationActuator; the support status row tells you.

• Raw data — pretty-printed Gamepad object snapshot, throttled to 100 ms.

Deadzone (top-right slider, 0.00–0.30) filters axis noise: values below threshold display as zero and don't contribute to triggers. Raw values are still recorded in JSON export.

Privacy: All data stays in your browser. The page makes no network calls (CSP connect-src 'none'). Settings (theme, deadzone, label scheme, vibration defaults) are stored in localStorage under the gptest: prefix.

Reset clears button hit counts, stick gamut points, simultaneity peak, and vibration log across all controllers. Export writes a JSON file with system info and per-controller stats.
