<h2>
Scope
</h2>
<p>
The Devices and Sensors WG defines client-side APIs that allow web
applications to make use of widely available device capabilities that
enable modern, context-aware, and interactive application
experiences. These capabilities include:
</p>
<ul>
<li>reacting to device power status
</li>
<li>preventing the screen from turning off under certain conditions
</li>
<li>preventing the system from turning off under certain conditions
</li>
<li>accessing nearby devices without physical contact
</li>
<li>responding to ambient light levels of the device’s environment
</li>
<li>reacting to changes in motion and orientation of the hosting device
</li>
<li>providing location information, either of the hosting device or a location selected by the user
</li>
</ul>
<p>
To fulfill its mission and to encourage broader engagement from
implementers and web developers alike, this WG is committed to
<strong>security and privacy focused</strong> and <strong>use
case-driven</strong> specification development.
</p>
<p>
As per the commitment to <strong>secure and
privacy-preserving</strong> specifications, APIs in scope that expose
sensitive data will define normative mitigations to address any
known security and privacy threats. These mitigations are developed
and reviewed together with the security and privacy community and
incorporated normatively into the respective specifications. In
addition, the WG produces non-normative security and privacy
explainers that describe concrete best practices, design patterns,
and mitigation strategies that cater to web developers to raise
awareness.
</p>
<p>
The group will document <strong>use cases and requirements</strong>
that inform the scope of the technical work to ensure the APIs limit
their functionality and data exposure to the minimum required to
implement real-world use cases adhering to the principles of data
minimization. Applicability of mitigation strategies such as data
quantization and permissions grants will be assessed on a use-case
basis considering the requirements derived from real-world use cases.
</p>
<p>
The WG will reuse existing security and privacy-focused web features
and APIs developed in other groups where applicable. If the existing
solutions do not provide the level of protection required, the WG
will explore innovative new security and privacy mechanisms.

Maintenance
</h3>
<p>
The Working Group will maintain errata and new editions, as
necessary, for the <a href=

API</a>, <a href=
"https://www.w3.org/TR/2016/REC-vibration-20161018/">Vibration

"https://www.w3.org/TR/2018/REC-html-media-capture-20180201/">HTML
Media Capture</a> W3C Recommendations.
</p>
<p class="issue">
<b>Note:</b> The Geolocation API is a joint deliverable with the <a href="https://www.w3.org/groups/wg/webapps">Web Applications Working Group</a>.
</p>
<p>
Since HTML Media Capture extends the <a
href="https://html.spec.whatwg.org/multipage/">HTML Living
Standard</a>, the Working Group may propose to W3C to upstream the
spec, to the WHATWG HTML LS for maintenance, as
anticipated by Section 10.2 of the <a

<h3>
Adding new Recommendation-track deliverables
</h3>
<p>
If additional in-scope Recommendation-track deliverables need to be
added to the Charter before the Charter expires, the Working Group
will prepare an updated Charter that differs only in deliverables.
</p>
<p>
The Working Group will not adopt new proposals until they have
matured through the <a href="https://www.w3.org/community/wicg/">Web
Platform Incubator Community Group</a> or another similar incubation
phase.

<h3>
Other Deliverables
</h3>
<p>
<strong>Use cases and requirements</strong> that inform the scope of
the technical work to ensure the APIs limit their functionality and
data exposure to the minimum required to implement real-world use
cases adhering to the principles of data minimization.
</p>
<p>
<strong>Security and privacy explainers</strong> that describe
concrete best practices, design patterns, and mitigation strategies
that cater to web developers to raise awareness.
