DeviceOrientationEvent

We'll use alpha (motion of the device around the z axis, expressed in degrees: 0^o to 360^o), beta (Front to back motion around the x axis, expressed in degrees :-180^o to 180^o) and gamma (Left to right motion around the y axis, expressed in degrees: -90^o to 90^o)

		
window.addEventListener('deviceorientation', function(event) {
    const alpha = event.alpha;
    const beta = event.beta;
    const gamma = event.gamma;
			...
});
