<p>The W3C has just published the first public WORKING DRAFT of the
WebXR Device API (<a class="moz-txt-link-freetext" href="https://www.w3.org/TR/2019/WD-webxr-20190205/">https://www.w3.org/TR/2019/WD-webxr-20190205/</a>).
This is not intended to be a fully fleshed out specification, but
an early draft to elicit comments from the public. <br>
</p>
<p>The API is the interface expressed in JavaScript between the user
code and the browser that controls much of the WebXR device
functionality or information. This includes things like setting up
the session, handling device orientation data, etc. It does not
include the rendering pipeline, and you still must call
window.requestAnimationFrame for each change to the display.</p>
<p>A very useful document is the WebXR Device API Explainer
(<a class="moz-txt-link-freetext" href="https://github.com/w3c/webvr/blob/master/explainer.md">https://github.com/w3c/webvr/blob/master/explainer.md</a>). This
document describes in non-spec language the philosophy behind the
spec document and may include more information than the spec WD in
areas that are not fully written.</p>
<p>If you find an issue (or more than one) with the spec document
you can report to the <a class="moz-txt-link-abbreviated" href="mailto:public-immersive-web@w3.org">public-immersive-web@w3.org</a> list (you need
to be a member of the list (see
<a class="moz-txt-link-freetext" href="https://lists.w3.org/Archives/Public/public-immersive-web/">https://lists.w3.org/Archives/Public/public-immersive-web/</a>) or to
any Immersive Web WG member
(<a class="moz-txt-link-freetext" href="https://www.w3.org/2000/09/dbwg/details?group=109735&order=org&public=1">https://www.w3.org/2000/09/dbwg/details?group=109735&order=org&public=1</a>).
Of particular interest are <br>
</p>
<ol>
<li>items that differ from the Explainer</li>
<li>items that cannot be done in JavaScript</li>
<li>items that are inconsistent within the WD specification</li>
<li>items that conflict with other W3C standards.<br>
</li>
