As of iOS 13 beta 2, you need to call DeviceOrientationEvent.requestPermission() to access to gyroscope or accelerometer. Users need to accept the request as well as the request needs to be called from a https origin. [link](https://medium.com/fla
<script>
function onClick(){
lg = document.getElementById('log');
lg.innerHTML = "Starting :";
if (typeof DeviceMotionEvent.requestPermission === 'function') {
// for IOS devices
document.getElementById("log").innerText = "IOS! ";
// get device orientation sensor data
DeviceOrientationEvent.requestPermission().then(response => {
if (response === 'granted') {
window.addEventListener('deviceorientation', OrientationHandler, true);
}else if (result.state === 'prompt') {
document.getElementById("log").innerText = "Need prompt!";
}else{
document.getElementById("log").innerText += "Not Supported!";
}
}).catch(console.error)
// get accelerometer data

// Handlers for data

document.getElementById('gamma').innerHTML = "gamma " + eventData.gamma;
