Connect a DualShock 4 through WebHID to check every button, stick, trigger, touchpad contact, motion sensor, battery reading, lightbar and rumble motor, and view the 3D sensor-motion visualization and firmware information.
Keep the controller still while calibrating, then move and rotate it. The 3D model combines gyroscope and accelerometer data.
The test displays digital buttons, analog sticks and triggers, up to two simultaneous touchpad contacts, raw gyroscope and accelerometer readings, battery level, charging state, connection type and HID report rate.
