Mission

As defined in its charter, the mission of the Device and Sensors Working Group is to create client-side APIs that enable the development of Web Applications and Web Widgets that interact with devices hardware, sensors, services and applications such as the camera, microphone, proximity sensors, native address books, calendars and native messaging applications.

Roadmap

As every Working Group, the Device and Sensors Working Group aims at gathering consensus on its specifications, both within the Working Group and with the community at large, working through an iterative process with implementors to ensure that the specifications are implementable and implemented.

The most recent version is highlighted.

As part of its technical work, the group ensures that its APIs are reviewed according to a checklist of good practices for APIs.

The history and past revisions of the documents drafts are available in the W3C public CVS server.

We use the W3C Github Web Platform Tests repository to manage our test suites, whose latest versions are available on W3C Test Server, w3c-test.org.

The Working Group has currently shelved the following work items, waiting for a better overall approach to emerge:

The Working Group is not planning to work on the following items:

APIs that have been suggested as worth consideration for the group but not currently prioritised (and therefore not up for discussion) are kept in the FutureWork page on the group's wiki.

Media Capture Task Force

This is a joint activity of the Device and Sensors Working Group and the Web Real-Time Communications Working Group. The work on the media capture API getUserMedia is done on the publicly archived mailing list: <public-media-capture@w3.org>. Additional information is available on the Media Capture Wiki.

We're tracking issues and action items using Tracker. You may see your actions using MyTracker.

Upon completing actions, please move them to the Pending status, and inform the WG with a summary of the action results, (including ACTION-# in the body of the message so it is linked to the action record). Text lists of pending actions and open actions are also available.

Zakim is being decommisioned, but in case we need it as a fallback, here is the information. Remember that we are using WebEx now, however. Zakim teleconference bridge: +1.617.761.6200 (VoIP: sip:zakim@voip.w3.org) code 3279

Minutes

Minutes are posted to the public list and once approved are linked from the meetings page, which also includes links to draft minutes.

Communications

The main communication channel for this group is the publicly archived mailing list <public-device-apis@w3.org>.

Patent Policy

This group operates under the W3C Patent Policy - see its Patent Policy status for more details.

History

The Working Group was first chartered in July 2009 as the “Device APIs & Policy Working Group”, as a follow-up to the workshop on Security for Access to Device APIs from the Web held in December 2008, then rechartered in August 2011 under the name “Device APIs Working Group”, and rechartered again in March 2016 under the name “Device and Sensors Working Group”.

The group used to work on the following documents, but their development has been stopped:

The following were submitted as starting points for this group's deliverables:
