LinearAccelerationSensor

The LinearAccelerationSensor interface of the Sensor APIs provides on each reading the acceleration applied to the device along all three axes, but without the contribution of gravity.

To use this sensor, the user must grant permission to the 'accelerometer' 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.

LinearAccelerationSensor()

Creates a new LinearAccelerationSensor object.

Inherits properties from its ancestors, Accelerometer, Sensor, and EventTarget.

LinearAccelerationSensor doesn't have own methods. However, it inherits methods from its parent interfaces, Sensor and EventTarget.

LinearAccelerationSensor doesn't have own events. However, it inherits events from its parent interface, Sensor.

Linear acceleration is typically read in the reading event callback. In the example below this occurs sixty times a second.

let laSensor = new LinearAccelerationSensor({frequency: 60});

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