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. See Feature-Policy
for implementation instructions.
Constructor
Gyroscope.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();
