Gyroscope

The Gyroscope interface of the Sensor APIs provides on each reading the angular velocity of the device along all three axes.

To use this sensor, the user must grant permission to the 'gyroscope' device sensor through the Permissions API.

If a feature policy blocks use of a feature it is because your code is inconsistent with the policies set on your server. This is not something that would ever be shown to a user. The Feature-Policy HTTP header article contains implementation instructions.

Constructor

Gyroscope()

Creates a new Gyroscope object.

Properties

Gyroscope.x Read only

Returns a double, containing the angular velocity of the device along the device's x axis.

Gyroscope.y Read only

Returns a double, containing the angular velocity of the device along the device's y axis.

Gyroscope.z Read only

Returns a double, containing the angular velocity of the device along the device's z axis.

Example

The gyroscope is typically read in the Sensor.onreading event callback. In the example below this occurs sixty times a second.

let gyroscope = new Gyroscope({frequency: 60});

gyroscope.addEventListener('reading', e => {
  console.log("Angular velocity along the X-axis " + gyroscope.x);
  console.log("Angular velocity along the Y-axis " + gyroscope.y);
  console.log("Angular velocity along the Z-axis " + gyroscope.z);
});
gyroscope.start();
