Web Accessibility Initiative
Activity statements provide a managerial overview of W3C's
work in each area, covering: an introduction to the activity, the goals
of W3C work, the accomplishments to date, and future plans. They are
designed to be read from beginning to end, to be informative and
interesting. The introductory section serves to set the scene and to
explain any technical concepts used in subsequent sections. Where
necessary the explanation is expanded into a short tutorial. The
role of W3C is given, also the benefits to the Web community,
accomplishments to date and a summary of what the future holds.
W3C's Web Accessibility Initiative is managed as a separate domain.
Introduction
Before the advent of the graphical user interface (GUI), most
human-computer interaction was text-based. A variety of adaptive
computing solutions enabled individuals with disabilities access to
computing, and for individuals with visual disabilities, the
technologies of screen magnification, speech synthesis, or
refreshable Braille display enabled efficient access.
The World Wide Web with its powerful GUI tools and wide variety
of information sources has made it possible for many people to
interact as never before. But Web content combines graphics, audio,
and video, hindering efficient communication for people with a wide
range of disabilities or functional limitations.
Goals of W3C work on Accessibility
To make the Web truly accessible to people with disabilities or
functional limitations. To achieve this by work on ensuring that all
W3C formats and protocols are accessible, by developing
recommendations for effective use of these features, and the
promotion and disemination of these guidelines. The following
sections will explain the nature of the problem and how the Web
Accessibility Initiative will address it.
Current barriers to accessibility
The Web's current status affects people with many types of
disability. For example:
-
unlabeled graphics can be undecipherable
to users with visual disabilities;
-
uncaptioned audio clips can be unintelligible
to users who are deaf or hard-of-hearing;
-
lack of keyboard support or consistent
navigation options can render Web applications and content unusable for
people with physical disabilities;
-
complex layouts can become barriers
for people with different kinds of cognitive disabilities.
Worldwide there are more than 750 million people with
disabilities. People with disabilities represent a substantially
unrecognized marketplace for information and for civic, educational,
economic and recreational interaction. An accessible Web has the
potential to reverse the information and economic isolation which
has so often been the outcome of traditional barriers to accessing
information for many people with disabilities.
Everyone benefits from improved accessibility
Ensuring access to the Web for people with disabilities also
benefits to non-disabled users:
- the speech-output interface developed for a blind user likewise
benefits sighted users engaged in eyes-busy activities such as
driving;
- the speech-input interface developed for a physically disabled
user benefits people engaged in hands-busy activities such as
surgery;
- captioned audio clips developed for a deaf or hard-of-hearing
user benefit hearing users browsing Web-based kiosks in noisy
shopping malls, and also enable functions such as text searching and
indexing on audio files;
- easily-navigable interfaces developed for people with cognitive
disabilities also facilitate browsing by users in highly distracting
settings where short-term memory or concentration are limited.
Role of the World Wide Web Consortium in Web Accessibility
Since its inception the W3C had an activity area devoted to
accessibility for individuals with disabilities, thanks to the
efforts of Mike Paciello of the Yuri Rubinsky Insight Foundation
(YRIF). While the members of the Consortium supported this area, the
effort did not receive significant W3C resources. In early 1997,
efforts by YRIF and others led to development of the Web
Accessibility Initiative (WAI) to be hosted by the W3C. The proposed
activity was described to W3C members in a February, 1997 Briefing
Package and supported by members and the Web Accessibility
Initiative launched in April, 1997. The activity encompasses five
areas of work where the W3C can have a major impact on increasing
the accessibility of the Web.
The WAI International Program Office was launched in October,
1997 subsequent to the availability of government and industry
funding. Consistent with the WAI Briefing Package, the WAI IPO
Director coordinates WAI work on technology, guidelines, and tools,
education and outreach, and research and development activities.
Also consistent with the WAI Briefing Package, the WAI IPO Director
ensures coordination with and participation of representatives of
government, research and disability organizations.
In order to coordinate these areas more efficiently, the WAI
technology, guidelines and tools work has moved from within the
Technology and Society Domain, and is now housed directly within one
domain, the Web Accessibility Initiative International Program
Office.
The five main areas of work for the Web Accessibility Initiative
are:
-
Technology development
Ensuring that the Web protocols and data formats, particularly HTML,
CSS, DOM, RDF, XML, XSL, HTTP and PICS, support accessibility
-
HTML/CSS Review Working Group
-
Protocols and Formats Review Working Group
- Guidelines for use of the technology
Developing comprehensive guidelines for accessibility of browsers,
authoring tools, and content development.
- Mark-up Guidelines Working Group
- User Interface Guidelines Working Group
- Authoring Tool Guidelines Working Group
- Development of tools
Developing tools to evaluate accessibility of web sites, and
prototypes to facilitate accessible page authoring.
- Rating and Certification Interest Group
- Education and outreach
Developing events, curriculum and
related materials to promote awareness of the need for Web
accessibility and educate content developers and other audiences as
to solutions for accessibility
- Education and Outreach Interest Group
- Research and advanced development
Monitoring research and advanced development of innovative user
interfaces, and prototyping of development as needed.
Activities and accomplishments to date
WAI activities and accomplishments during the past 6 months
included the following:
- WAI Working Group and Interest Group meetings, Cambridge, MA,
