The Accelerometer
interface of the Sensor APIs provides on each reading the acceleration applied to the device along all three axes.
To use this sensor, the user must grant permission to the 'accelerometer'
, device sensor through the Permissions
API.
If a feature policy blocks the 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
Accelerometer.Accelerometer()
- Creates a new
Accelerometer
object.
Properties
Accelerometer.x
Read only- Returns a double containing the acceleration of the device along the device's x axis.
Accelerometer.y
Read only- Returns a double containing the acceleration of the device along the device's y axis.
Accelerometer.z
Read only- Returns a double containing the acceleration of the device along the device's z axis.
Example
Acceleration is typically read in the Sensor.onreading
event callback. In the example below this occurs sixty times a second.
let acl = new Accelerometer({frequency: 60}); acl.addEventListener('reading', () => { console.log("Acceleration along the X-axis " + acl.x); console.log("Acceleration along the Y-axis " + acl.y); console.log("Acceleration along the Z-axis " + acl.z); }); acl.start();
