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. See Feature-Policy
for implementation instructions.
Constructor
LinearAccelerationSensor.LinearAccelerationSensor()
- Creates a new
LinearAccelerationSensor
object.
Properties
Inherits properties from its ancestor, Accelerometer
.
Example
Linear acceleration is typically read in the Sensor.onreading
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();
