Making web sites for a mobile devices and people with disabilities

The World Wide Web Consortium has released the final version of "Shared Web Experiences: Barriers Common to Mobile Device Users and People with Disabilities". This is intended to help those designing web sites for both mobile and disabled users. It catalogues the overlap between the W3C's mobile and accessibility standards. This is useful, but is is disappointing that W3C have failed to get their standards writers to agree on one common standard. Instead of having on standard, the W3C has two standards which say much the same thing, and leave it to each web designer to try to reconcile the differences themselves.

UK Government fails own web accessibility guidelines

The UK Government's Central Office of Information (COI) has set a minimum standard of accessibility for public sector websites. Unfortunately their web site detailing the policy fails to meet the standard set, makes misleading claims of conformance with the standard and does not comply with their own guidelines.

The COI has set a minimum standard of accessibility for new UK public sector websites at Level Double-A of the W3C Web Content Accessibility Guidelines . This is required as of December 2009 for central government departments and March 2011 for central government executive agencies and non-departmental public bodies.

The COI suggests using free and commercially available automated testing tools as part of measuring accessibility. However, applying one such test, the Web Accessibility Test (TAW), the COI's page failed with eight level 2 problems (excerpt of the report appended). This indicates that the page does not meet at Level Double-A of the W3C Web Content Accessibility Guidelines. The problems with the page are minor and easily corrected.

The COI's help page, states that the "... website's objective are to conform to the Guidelines for UK government websites, which support the W3C's Web Content Accessibility Guidelines 1.0, Level AA, to ensure a Web accessibility standard have been achieved and are maintained." The statement is misleading, as it suggests the web site meets Level Double-A, when it does not. Also the statement does not use the wording suggested in COI's own policy document.

In contrast the Australian Government accessibility policy requires a lower level of compliance, to Level A of the W3C guidelines. The web page from the Australian Government Information Management Office (Australian equivalent to UK COI) stating this requirement not only meets this requirement, but exceeds it, passing the more stringent automated Level Double-A test (excerpt appended), which the UK COI failed.

Accessibility

1. Human review2. Human reviewThis item is a mandatory requirement

Accessibility is a general term used to describe the degree to which a system is usable by as many people as possible without modification. Web pages often have access issues for people with disabilities or with technological constraints.

Australian Government departments and agencies are also required to maximise their use of new technologies by ensuring that their websites address access and equity issues for people from culturally and linguistically diverse backgrounds.

Tell Me About?

The Australian Government aims to achieve fairer and more accessible government services and programs through its Access and Equity Strategy. The strategy seeks to promote fairness and responsiveness in the design, delivery, monitoring and evaluation of government services in a culturally diverse society.

The Government's Access and Equity Strategy is guided by the Access and Equity Framework (Department of Immigration and Citizenship) formerly known as the Accessible Government Services for All Framework. It was developed in 2006 in consultation with Australian Government agencies, taking into account their ability to contribute both as separate portfolios and to whole-of government responses to the challenges faced by our culturally diverse nation.

Its four principles, and the corresponding performance indicators, address key responsibilities of government:
  • Responsiveness – Extent to which programs and services are accessible, fair and responsive to the individual needs of clients
  • Communication – Open and effective channels of communication with all stakeholders
  • Accountability – Effective and transparent reporting and review mechanisms
  • Leadership – A whole of government approach to management of issues arising from Australia’s culturally and linguistically diverse society.

The framework suggests strategies for the implementation of these principles. It aims to assist agencies to analyse their performance and better share good practice responses to challenges and opportunities.

Progress in implementing the Access and Equity Strategy is published in the Access and Equity Annual Reports (Department of Immigration and Citizenship).

Why Must I?

Under the Disability Discrimination Act 1992 agencies must ensure that people with disabilities have the same fundamental rights to access information as the rest of the community.

Under the Commonwealth Disability Strategy, (Department of Families, Housing, Community Services and Indigenous Affairs) Australian Government agencies are obligated to remove barriers which prevent people with disabilities from having access to their policies, programs and services.

Under the 2000 Government Online Strategy departments and agencies are required to comply with the Web Content Accessibility Guidelines 1.0 (World Wide Web Consortium).

Agencies must achieve level "A" conformance (all Priority 1 checkpoints are satisfied), and it is recommended that agencies achieve level "AA" conformance (all Priority 1 and Priority 2 checkpoints are satisfied).

The W3C guidelines explain how to make web content accessible to people with disabilities. However, following them will also make web content more available to all users. These guidelines do not discourage content developers from using images, video, etc., but rather explain how to make multimedia content more accessible to a wide audience.

The Web Content Accessibility Guidelines

The W3C guidelines provide a series of checkpoints that can be used to ensure that websites are accessible. Each checkpoint has a priority level assigned by the Working Group based on the checkpoint's impact on accessibility.

Priority 1

W3C states that a web content developer must satisfy this checkpoint. Otherwise, one or more groups will find it impossible to access information in the document. Satisfying this checkpoint is a basic requirement for some groups to be able to use Web documents.

Level of Compliance: The Human Rights and Equal Opportunity Commission's view is that compliance with the W3C WCAG 1.0 guidelines to the Single-A level is a minimum rather than a desirable outcome. Websites that demonstrate such compliance may still be difficult or impossible to access for many users with a disability.

Priority 2

W3C states that a web content developer should satisfy this checkpoint. Otherwise, one or more groups will find it difficult to access information in the document. Satisfying this checkpoint will remove significant barriers to accessing Web documents.

Priority 3

W3C states that a web content developer may address this checkpoint. Otherwise, one or more groups will find it somewhat difficult to access information in the document. Satisfying this checkpoint will improve access to Web documents.

How Do I?

The Human Rights and Equal Opportunity Commission provides information on World Wide Web Accessibility standards, guidelines, tools and techniques.
