LinearAccelerationSensor

Secure context

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. In addition, this feature may be blocked by a Permissions Policy set on your server.

Constructor

• LinearAccelerationSensor()
  • : Creates a new LinearAccelerationSensor object.

Instance properties

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

Instance methods

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

Events

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

Example

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();
