Gyroscope test

This gyroscope test reads motion and orientation data from your device while the page is open. Turn or tilt your device and watch the readings change. The page also shows a level and a compass heading, so you can check several motion sensors in one place.

The test uses the device's reported orientation angles, rotation rate, acceleration, and sampling interval. Acceleration is shown both with gravity and without it. These are live readings, so they can change as the device moves or as it sends new sensor data.

Alpha, beta and gamma are orientation angles reported by the device. They describe how its orientation changes as you turn and tilt it.

Rotation rate shows how quickly the device is turning. Acceleration with gravity includes the effect of gravity, while acceleration without gravity removes that effect from the displayed reading. The sampling interval tells you the time between sensor readings.

The level is a visual aid for checking whether the device is tilted. The compass heading shows the direction the device reports. On iPhone, the heading comes from its compass reading; on Android, it comes from absolute orientation. The test does not provide a pass score for these readings.

For a basic check, move the device and see whether the orientation, rotation rate or acceleration readings respond. The level and heading should also display a reading when the device provides the data. A changing value shows that the page is receiving that kind of sensor information, but it does not prove that every sensor function is working correctly.

The page does not set a numeric threshold for a good result. Judge the readings by whether they appear and respond to movement, and whether the level or compass heading is available. A missing reading or values that do not respond can mean the device did not provide that sensor data to the page.

If the page shows that there are no motion sensors to read, the device is reporting that motion data is unavailable. This is the expected message on desktop in this test. A phone can also show missing or unchanged readings if motion access was not granted or if its sensor data is unavailable.

On iPhone, tap the permission prompt to let the page read motion data. Then move the device again and check whether the readings respond. The guide can help you check the issue, but it does not guarantee a fix.

The compass test shows the heading supplied by the device, and the level shows tilt. These displays are useful for checking whether the page receives those readings as you move the device.

This is a device sensor check, not a hearing or health test. It reports the data available to the page and cannot establish why a sensor reading is absent or whether the device has a hardware fault.
