[compass] Re: Compass API

Lesley

The specification you are referencing is old and out of date - work on the System Information API  in DAP has been stopped ('shelved') [1].

The work you are interested in has moved [2]  to the  W3C Geolocation Working Group [3]. 

You should look at the "DeviceOrientation Event Specification", Editor's Draft 13 June 2012  and raise any questions on the Geolocation Working Group mail list.

The specification is at  http://dev.w3.org/geo/api/spec-source-orientation.html

I hope this helps. Apologies for the delay in responding, I was traveling on business.

regards, Frederick

Chair, W3C DAP Working Group
