$(document).on({
  deviceready: function () {
    if (!('ondevicemotion' in window)) {
      navigator.accelerometer.watchAcceleration(function (acceleration) {
        var event = document.createEvent('Event');
        event.initEvent('devicemotion', true, true);
        event.accelerationIncludingGravity = acceleration;
        window.dispatchEvent(event);
