Accelerometer.x

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The x read-only property of the Accelerometer interface returns a double precision integer containing the acceleration of the device along its x axis.

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.

Value

Examples

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

const accelerometer = new Accelerometer({ frequency: 60 });

accelerometer.addEventListener("reading", (e) => {
  console.log(`Acceleration along the X-axis ${accelerometer.x}`);
  console.log(`Acceleration along the Y-axis ${accelerometer.y}`);
  console.log(`Acceleration along the Z-axis ${accelerometer.z}`);
});
accelerometer.start();
