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

The DeviceMotionEvent provides web developers with information about the speed of changes for the device's position and orientation.

Warning: Currently, Firefox and Chrome do not handle the coordinates the same way. Take care about this while using them.
