<h1>Description</h1>
<p>
After hitting the button below, your device must vibrate for a short period of time (roughly one
second). If it vibrates for a longer time (roughly five seconds, it should feel somewhat long) then
the test has failed.

<button id='vib'>Vibrate!</button>
<script>
if (undefined !== navigator.vibrate) {
document.getElementById("vib").onclick = function () {
navigator.vibrate(5000);
setTimeout(function () {
navigator.vibrate([]);
}, 1000);
};
