Add way of getting current orientation about deviceorientation HOT 6 CLOSED

Agreed and we are also currently working on a native Promise-based API for this.

In the mean time, you could use a library like Full Tilt JS https://github.com/richtr/Full-Tilt-JS. It simply dumps the last DeviceOrientation event object to a variable until you call a sync API function in e.g. requestAnimationFrame. At that point it performs more complex processing of the last known device orientation data.

Full Tilt JS performance benchmarking is available at http://jsperf.com/screen-adjusted-deviceorientation-benchmark.

Where is the work happening and who is involved? I tried looking for branches and PRs but couldn't find any.

Our draft Promises proposal has now been published on the W3C Device APIs mailing list @ http://lists.w3.org/Archives/Public/public-device-apis/2014Sep/0024.html.

It's definitely lacking. Alternatively or in addition, any thoughts on normalizing the spec for all browsers to star firing Device Orientation on the same time frame at the 'interactive' state of the document, so it can be used at or before DOMContentLoaded?

Added label of VNext. This can be considered as part of Generic Sensor API work.

I propose closing this issue as "won't fix". A Promise-returning API can easily be polyfilled like so,

function getCurrentOrientation() {
  return new Promise((resolve) => {
    document.addEventListener('deviceorientation', (event) => {
      resolve(event);
    }, {once: true});
  });
}

The Observable proposal would also extend all EventTargets so that you could write:

let event = (await document.on('deviceorientation').take(1).toArray())[0];
