BUTTONSCOPE / Labs & learning
Controller lab
Inspect the name, mapping, button values and axes exposed through Gamepad API.
Controller vibration check
Send a short, low-intensity vibration request only when the browser and controller provide an actuator.
Controller stick trajectory
Draw the paths of available stick-axis pairs while slowly rotating each stick.
Controller deadzone preview
Preview an axis-by-axis deadzone transformation without changing the controller or game settings.
Controller stick drift observation
Record stick-axis values at rest for a chosen period and review the observed peak radius.
Controller button and trigger test
Inspect the name, mapping, button values and axes exposed through Gamepad API.
Choose a focused test below. Use the same browser and connection when comparing runs. A recorded event is evidence of browser input, not a complete hardware diagnosis.
