Test de mouvement et de boussole
Lisez les données de l'accéléromètre, du gyroscope et de la boussole, le cas échéant, avec un niveau à bulle et un affichage d'orientation en direct.

- Click Enable sensors and grant motion permission if your browser asks.
- Tilt the device and watch the bubble level and axis values.
- Rotate the device to check compass behaviour where supported.
- Stop the test to remove event listeners and end sensor access.

Explication technique
The Generic Sensor API and DeviceOrientation/DeviceMotion events expose orientation and motion depending on platform. iOS requires an explicit permission request after a gesture; many desktops expose no motion sensors at all.
Compass readings can be affected by magnetic interference from cases, speakers, and metal surfaces. A browser cannot calibrate the sensor or prove that a reading is physically accurate.
Dépannage
Sensors are unsupported
Desktop browsers often have no motion sensors. Use a mobile device with the required hardware.
Permission request does not appear
On iOS, call the permission prompt from a direct user gesture and ensure the page is served over HTTPS.
Values drift
Magnetic interference and sensor fusion algorithms can cause drift. Move away from magnets and metal objects.
Compass points the wrong way
Compass accuracy varies by device and environment. Do not rely on it for navigation.
