Gamepad tests
Check detection, buttons, triggers, centre drift, estimated deadzone and stick range.
Start the general testGamepad test
See what the browser receives from your controller in real time, then use the guided checks to spot missing or irregular responses.
Stick drift test
Sample each stick at rest and distinguish a stable neutral position from a repeated offset that may indicate stick drift.
Gamepad deadzone test
A guided slow-movement test estimates the neutral area where stick movement is not yet reported reliably.
Gamepad circularity test
Trace the outside edge of the stick to see whether its reported shape and maximum reach are balanced across directions.
