In Australia the Disability Discrimination Act 1992 (DDA) makes it is unlawful to discriminate against disabled people. The Web Accessibility Initiative (WAI) of the World Wide Web Consortium (W3C) has published access guidelines to assist making accessible web pages. Australian governments and companies have adopted the WAI Guidelines to assist with implementing the DDA.

In the USA Section 508 of the 1974 Rehabilitation Act (commonly referred to as "508") prohibits U.S. federal agencies from buying, developing, maintaining, or using web based technology that is inaccessible to people with disabilities. The criteria for web-based technology for 508 are based on the WAI Guidelines, but with some variations.

Australian web site developers need to be aware of the WAI and 508 guidelines, as many web sites will be viewed in the USA, as well as Australia. Macromedia provides accessibility tools for Section 508 and W3C.

What is accessibility?

For those unfamiliar with accessibility issues pertaining to Web page design, consider that many users may be operating in contexts very different from your own:

Web accessibility guidelines have been developed to assist designers to make web sites which are available to the greatest range of users of the Internet.

From W3C Recommendation Web Content Accessibility Guidelines 1.0, 5-May-1999, URL: http://www.w3.org/TR/1999/WAI-WEBCONTENT-19990505

A common misconception that web accessibility issues are only to do with the blind. Blindness is only one disability which can be addressed. The Australian Human Rights and Equal Opportunity Commission reported in 2000 that a group with accessibility problems is the aged < http://www.humanrights.gov.au/disability_rights/inquiries/ecom/ecomrep.htm>.

The simplest accessibility feature built into the web is alternative text for images. The HTML image command (IMG) includes an optional alternate text (ALT) tag. This allows a text caption to be entered, which is displayed when the image can not be seen. Web authors just need to type in the captions when adding images.

The W3C Guidelines

The W3C established a Web Accessibility Initiative (WAI) to set priorities to serve as a guide for Web developers. The guidelines were divided into three priority levels: 1, 2 and 3, each with checkpoints. Here are some a Priority 1 checkpoint:

As an example any photograph used on a web site should have a text caption, for those who are unable to see the photo.

Another Priority 1 checkpoint:

As an example if images of gold, silver and bronze medals are used to indicate who won a race, then make the medals different shapes and include a text description for those who can't distinguish the colors.

There are three levels of conformance corresponding to the three priority levels:

Conformance Level Priority Checkpoints to be Satisfied
A all 1
Double-A all Priority 1 and 2
Triple-A all Priority 1, 2, and 3

The Australian Situation

Australian governments and industry bodies have, in general, adopted the World Wide Web Consortium's Accessibility Guidelines. Details vary as to what level of compliance is specified (if any) as to if compliance is recommended or mandatory.

Disability Discrimination Act 1992

In Australia the Disability Discrimination Act 1992 makes it is unlawful to discriminate against disabled people. Unlike the USA's Section 508, the Australian legislation applies to private companies, as well as local, state and federal government agencies. Section 24 of the Act ("services and facilities") states:

  1. It is unlawful for a person who, whether for payment or not, provides goods or services, or makes facilities available, to discriminate against another person on the ground of the other person’s disability or a disability of any of that other person’s associates:
    1. by refusing to provide the other person with those goods or services or to make those facilities available to the other person; or
    2. in the terms or conditions on which the first-mentioned person provides the other person with those goods or services or makes those facilities available to the other person; or
    3. in the manner in which the first-mentioned person provides the other person with those goods or services or makes those facilities available to the other person.
  2. This section does not render it unlawful to discriminate against a person on the ground of the person’s disability if the provision of the goods or services, or making facilities available, would impose unjustifiable hardship on the person who provides the goods or services or makes the facilities available.

From Disability Discrimination Act (1992), Section 24: http://www.austlii.edu.au/au/legis/cth/consol_act/dda1992264/s24.html

In August 2000 the Australian Human Rights and Equal Opportunity Commission found than an organisation had engaged in unlawful conduct by providing a web site which was to a significant extent inaccessible to the blind. In his decision Commissioner Carter used the W3C Guidelines to assess accessibility of the web site:

The first question therefore is whether the respondent discriminated against the complainant in providing to the complainant its web site in a form which resulted in the site being inaccessible to him or only partly so. The question of ensuring accessibility to the World Wide Web by persons with disabilities was addressed in the World Wide Web Content Accessibility Guidelines which are generally referred to as the W3C Guidelines.

From "Reasons For Decision Of The Hon William Carter QC", Human Rights and Equal Opportunity Commission, 28 August 2000: https://www.humanrights.gov.au/bruce-lindsay-maguire-v-sydney-organising-committee-olympic-games

The Australian Human Rights and Equal Opportunity Commission provides Advisory Notes with advice on avoiding disability discrimination when designing web pages and background information on accessibility and legal issues. The Commission recommends the use of W3C and AusInfo guidelines:

The AusInfo Guidelines give sound advice on a wide range of issues in electronic publishing including access for people with disabilities. The Commission believes that integrating accessibility into general authoring and publishing advice is a good way of bringing it into mainstream practice. The AusInfo Guidelines are intended to evolve to keep pace with best practice. The Commission believes that reasonable attempts to achieve current best practice will generally satisfy the access requirements of the DDA.

From: World Wide Web Access: Disability Discrimination Act Advisory Notes, Version 3.1, May 1999: http://www.hreoc.gov.au/disability_rights/standards/www_3/www_3.html

The Commission does not specify a particular level (A, Double-A or Triple-A) of compliance with W3C guidelines.

Government Common Minimum Standard

In June 2000 ministers from the Commonwealth, State and Territory Governments agreed to a common minimum web site access standard:

The Council agreed to the adoption of the World Wide Web Consortium's Web Content Accessibility Guidelines as the common best practice standard for all Australian government websites. This decision should ensure that people with disabilities or technical constraints can use online resources provided by Australian governments. The Guidelines are widely recognised internationally, and have the support of Australia's Human Rights and Equal Opportunity Commission, disability groups and rural groups.

Adoption of common standards by all Australian governments will promote the confidence of users in online services, and the accessibility of online government information and services. The guidelines set out ways to present information which will enhance access, for example, by providing website material on a text only basis to facilitate the use of screen readers by those with visual impairments, and reducing the use of graphics to enhance download times. <http://www.dcita.gov.au/nsapi-graphics/?MIval=dca_dispdoc&ID=5092>

The Council did not specify a level of compliance required for the W3C Guidelines.

In the Federal Government sector, the National Office for the Information Economy undertakes promotion of accessibility standards:

The AccessAbility Online Resource at http://accessability.noie.gov.au aims to raise awareness of the accessibility issues faced by people with disabilities who wish to use online services. It provides detailed information on a wide range of issues, products andb services associated with access to online services for people with disabilities. Among other things, it includes information on hardware and software products, standards development, training and education issues, support programs, policy papers and case studies, both from Australia and key international sources.
< http://www.govonline.gov.au/projects/standards/accessibility.htm>

NSW

The guidelines for NSW Government Agencies, recommend that accessible content be developed as a standard feature of web pages and the W3C Web Content Accessibility Guidelines be used, with Priority 1 and 2 Checkpoints applied as a minimum (that is level double-A).

Victoria

The WWW Accessibility (Disability) Policy for the Government of Victoria states that "Departments should design their web sites to promote equal access for people with disabilities and departments "should obtain at least the first level of compliance", with W3C Guidelines (that is level A).

Victorian Local Government Act

The Local Government Act imposed on of Victorian Councils an obligation to ensure that Councils seek the best value in providing services. The Best Value Principles include in section 208B:

(c) each service provided by a Council must be accessible to those members of the community for whom the service is intended; ...

(f) a Council must report regularly to its community on its achievements in relation to the principles ...

<http://www.austlii.edu.au/au/legis/vic/consol_act/lga1989182/s208b.html>

Queensland

The Queensland Government Information Architecture requires the home page of Agency web sites to meet W3C Priority 1 and 2 (That is Level Double-A). All Queensland Government web pages must also use ALT tags for all descriptive graphics. A Best Practice Supplement provides more details.

SA

Under the Government Website Protocols, South Australian Government websites are required to comply with the World Wide Web Access: Disability Discrimination Act Advisory Notes, of the Human Rights and Equal Opportunity Commission, which does not specify a particular level of compliance.

WA

The WA Government's E-commerce web site "Standards and Best Pratice" cites the Online Council's adoption of the W3C Web Content Accessibility Guidelines as the common best practice standard for all Australian government web-sites. The Council did not specify a level of compliance required for the W3C Guidelines.

ACT

The ACT Government Website Guidelines: require agency web sites to satisfy all W3C priority 1 checkpoints (that is Level A compliance).

Australian Bankers’ Association Industry Standard on Internet Banking

The Australian Bankers’ Association issued a draft "Industry Standard for Internet Banking" on 30 November 2001 as part of an initiative to improve accessibility of electronic banking services. After public consultation, the standard will be available for voluntary adoption by banks:

The Australian Bankers' Association and its members are working together with the community to improve accessibility of electronic banking services and are contributing to efforts to narrow the digital divide. Under the leadership of the ABA, representatives from member banks, other financial institutions, community groups and retailers have developed draft Industry Standards on electronic banking services. Submissions from any interested parties are sought on the draft Industry Standards by January 31, 2002.
<http://www.bankers.asn.au/ABA/Online/>

IIA/AIMIA - Accessibility Web Action Plan

The Internet Industry Association (IIA) and Australian Interactive Multimedia Industry Association (AIMIA) prepared a joint Accessibility Web Action Plan aimed at encouraging awareness about web accessibility and helping their members to work towards building and maintaining accessible websites:

To support this direction, IIA and AIMIA have agreed to the adoption of the World Wide Web Consortium's Web Content Accessibility Guidelines as the common best practice standard for all Australian websites. This decision will ensure that people with disabilities or those experiencing technical constraints, can use the online resources provided by Australian websites. These guidelines are widely recognised internationally, and have the support of Australia's Human Rights and Equal Opportunity Commission (HREOC), disability groups and rural groups.

IIA/AIMIA intends the document to be used as a template by others and has placed no copyright or commercial confidentiality restrictions on the text.

Accessibility In the United States

Section 508 of the U.S. 1974 Rehabilitation Act prohibits federal agencies from buying, developing, maintaining, or using electronic and information technology that are inaccessible to people with disabilities. As of June 21, 2001 all federal agencies were mandated to have their web sites compliant to section 508. The regulation is available at: http://www.usdoj.gov/crt/508/508law.html

The Center for IT Accommodation (CITA) of the U.S. General Services Administration provides a 508 Website, which includes a summary of the standards: http://www.section508.gov/

Web-based Intranet and Internet Information and Applications (1194.22)

The criteria for web-based technology and information are based on access guidelines developed by the Web Accessibility Initiative of the World Wide Web Consortium. Many of these provisions ensure access for people with vision impairments who rely on various assistive products to access computer-based information, such as screen readers, which translate what's on a computer screen into automated audible output, and refreshable Braille displays. Certain conventions, such as verbal tags or identification of graphics and format devices, like frames, are necessary so that these devices can "read" them for the user in a sensible way. The standards do not prohibit the use of web site graphics or animation. Instead, the standards aim to ensure that such information is also available in an accessible format. Generally, this means use of text labels or descriptors for graphics and certain format elements. (HTML code already provides an "Alt Text" tag for graphics which can serve as a verbal descriptor for graphics). This section also addresses the usability of multimedia presentations, image maps, style sheets, scripting languages, applets and plug-ins, and electronic forms.

The standards apply to Federal web sites but not to private sector web sites (unless a site is provided under contract to a Federal agency, in which case only that web site or portion covered by the contract would have to comply). Accessible sites offer significant advantages that go beyond access. For example, those with "text-only" options provide a faster downloading alternative and can facilitate transmission of web-based data to cell phones and personal digital assistants.

From "Summary of Section 508 Standards", Center for IT Accommodation (CITA) of the U.S. General Services Administration: https://web.archive.org/web/20011217224528/http://www.section508.gov/final_summary.html#web

There are sixteen Section 508 web requirements (known as Section 1194.22, Paragraphs a to p). The first eleven Section 508 web requirements correspond with the priority 1 Checkpoints of the W3C's Web Content Accessibility Guidelines:

Section 1194.22 Paragraph WCAG 1.0 Checkpoint
(a) 1.1
(b) 1.4
(c) 2.1
(d) 6.1
(e) 1.2
(f) 9.1
(g) 5.1
(h) 5.2
(i) 12.1
(j) 7.1
(k) 11.4
From "1194.22 Web-based intranet and internet information and applications, Section 508 Standards", Center for IT Accommodation (CITA) of the U.S. General Services Administration: https://web.archive.org/web/20100617124828/http://www.section508.gov/index.cfm?FuseAction=Content&ID=12#Web

The remaining five Section 508 web requirements are different, and in addition to, the W3C's WCAG 1.0, level A (i.e., all priority 1 checkpoints):

(l) When pages utilize scripting languages to display content, or to create interface elements, the information provided by the script shall be identified with functional text that can be read by assistive technology.

(m) When a web page requires that an applet, plug-in or other application be present on the client system to interpret page content, the page must provide a link to a plug-in or applet that complies with §1194.21(a) through (l).

(n) When electronic forms are designed to be completed on-line, the form shall allow people using assistive technology to access the information, field elements, and functionality required for completion and submission of the form, including all directions and cues.

(o) A method shall be provided that permits users to skip repetitive navigation links.

(p) When a timed response is required, the user shall be alerted and given sufficient time to indicate more time is required.

From "1194.22 Web-based intranet and internet information and applications, Section 508 Standards", Center for IT Accommodation (CITA) of the U.S. General Services Administration: https://web.archive.org/web/20100617124828/http://www.section508.gov/index.cfm?FuseAction=Content&ID=12#Web

Macromedia provides a point by point (a-p) tutorial of how to conform to the standards using Dreamweaver entitled 508 Web Development Guidelines: download them at: http://www.macromedia.com/macromedia/accessibility/

Which Accessibility Standard Should I Use?

Macromedia provide accessibility solutions covering both Section 508 and level 1 W3C/WAI guidelines. Many new to Web accessibility often ask “which standard should I use?”. The answer will vary depending on the company or organization you work for. If producing web sites for Australian use, then W3C Conformance Level "A" (all priority 1 checkpoints) should be the minimum. If the web pages are to be used in the USA, it would be prudent to also meet the standards set forth in Section 508. Many businesses in the United States are now choosing to conform to Section 508.

Retrofitting Your Web Site for Accessibility Standards Conformance

Macromedia recommends the following steps for retrofitting your Web site for Accessibility Standards conformance:

  1. Designer Awareness
  2. U.S Accessibility Standards
  3. Evaluating Websites for Accessibility
  4. Tool and Techniques
  5. Validation Of Accessible Website

Designer Awareness

The challenge for Federal Web designers and developers is how to create access that is “comparable to the access available to others.” While it may be easy to skim over these key words, they do play a critical role in understanding how to create and implement a site that is equitable for those who are blind, or have low vision or other varying abilities. The Internet is a strongly visual medium based mostly on HTML coding hidden behind the graphic interfaces or, more commonly termed, Web pages. Many developers readily assume that everyone accesses the Web with similar skill sets and abilities and may have little awareness of how persons with disabilities access the web. A general understanding of assistive technology tools (such as screen readers), and how they interface with HTML is a good first step toward creating technical awareness of the issues. It is also useful for developers to have a general familiarity with the range of abilities persons with disabilities may or may not possess. The W3C serves as a good resource to glean an understanding of both assistive technology tools and the varying skill sets of persons with disabilities <http://www.w3.org/TR/2001/WD-UAAG10-20010409/>.

Once developers have gleaned a greater awareness of assistive tools and how persons with disabilities interact with these tools it becomes evident to developers why it is important to follow universal design principals when retrofitting Web sites.

Design

Designers tend to build Web sites based on their own personal preference and experience. A designer with a personal preference for visual learning may build a site with graphics and animation, while another designer with a preference for simple text may develop a site that is dense with words and has minimal graphics. Developers also tend to use products they have the most familiarity with, rather than those products that could provide flexibility and inclusiveness in design for accessibility.

To build fully compliant sites, designers must be aware of their own personal design bias and the W3C guidelines, but, most importantly, they must develop an expertise with the tools essential for building accessible Web sites.

UsableNet™ notes two key design elements for building accessible Web sites:

Web Segregation vs. Designing for Accessibility

For many Web designers, site segregation is a quick solution. This is a method by which Web designers provide accessible websites by creating text-only companion site. This text-based site is generally a stripped down version of the full Web site and lacks such descriptive elements as interactive videos, graphics, combination text and graphic charts and tabular or framed information which may be provided in the full Web site.

But, designers can move beyond this commonly used – and less imaginative -- practice of segregated sites to provide high quality and accessible design.

Making Rich Media Accessible

Web developers can create fully integrated rich media Websites that provide descriptive information about each element (in text and/or audio as appropriate) through the use of alt tags, d-links, and longdesc tags. Macromedia provides an example of how to implement an integrated rich media site in our rich media template. This template demonstrates how to create accessible Flash movies, and banners, Fireworks buttons, along with Dreamweaver and Ultradev. Additional digital assets such as images, dynamic tables, forms, and audio files are demonstrated as well. This template can be found at www.macromedia.com/accessibility

An accessible site not only provides full access for people with disabilities, but also provides comprehensive access to all users. Designing for and implementing accessibility incorporates the basics of good design theory: simplicity of design with ease of use. Designing for Web accessibility should include providing the multiple views essential for each information asset on a website.

Staged Rollout

Many government Web developers are in charge of volumes of information that will need to be made fully accessible over a period of time. Jakob Nielsen, in his article on “Disabled Accessibility, The Pragmatic Approach”, offered many tips for retrofitting a Web site noted below are a few key of his key points:

“The official standard tells you what ought to be done. In practice, it is necessary to prioritize standard-compliance on large sites and plan a staged roll out of accessibility:

Evaluating for Accessibility Standards Conformance

The road to accessibility standards conformance conformance is not as difficult as it may first appear. There are a host of resources and tools available to both evaluate websites for conformance and guide developers through the essential steps necessary to retrofit websites.

There are three progressive steps developers need to take in order to adequately retrofit their websites for accessibility:

  1. Learn the standards and the necessary skill to implement accessibility techniques;
  2. Utilize tools available to evaluate the website for conformance.
  3. Adequately retrofit and validate the website for the quality of its accessibility design and appropriately describe and tag of its digital assets.

Checklist for Evaluating for Website Accessibility Standards Conformance:

  1. Identify your website and the many digital assets that comprise the Website
  2. Use the Dreamweaver Ultravedev Accessibility Suite (an extension for accessibility is part of the Suite) to assess your website. The accessibility extension will allow you to choose either Section 508 or W3C priority 1 as the standard to evaluate the Website. Once the accessibility extension has evaluated the Website it will produce a report that will locate each portion of the Website that needs retrofitting for accessibility.
  3. Retrofit the Website for accessibility using both the 508 Accessibility Suite in Dreamweaver as the accessibility extension will note how to fix the problem and the Standards provide examples of techniques as well.
  4. Run the Accessibility extension again this time to confirm and validate the Website has been retrofitted for accessibility.

Identify the Type of Web Site

Most full-time Web designers know the type of website they manage, but many Web masters work part-time or less, and may need additional information to define their site. There are three general types:

The majority of Web sites managed by Government and educational institutions fall into the first two categories. However, many Web sites are increasingly sophisticated, and the strong market trend toward data-driven Web delivery via uniform standards is raising the complexity of Web site design and development.

Evaluate, Retrofit and Validate the Website with the Dreamweaver Ultradev 508 Accessibility Suite

The Dreamweaver Ultradev Accessibility Suite can be used to retrofit Web sites for accessibility. Just download the Dreamweaver or UltraDev extension, read the relevant guidelines, and fix as needed. As new pages are developed, create a list of usability rules, based on the 508 standards, and use the extension to check each page for compliance as the Website is edited. Macromedia has partnered with UsableNet and others to assist designers with the tools, training, and support needed to evaluate current sites for compliance and to retrofit existing Websites.

The Dreamweaver Ultravdev 4 Usablenet 508 Accessibility Suite

The “Accessibility Extension” adds new features to ease 508/W3C Website evaluation. This tool provides a host of features to streamline assessment of Web sites for accessibility compliance. It will:

Designing and Implementing Accessibility Solutions in Education

Accessibility is an issue of growing importance for educational institutions. For educators around the world, accessibility is the right thing to do and in many instances is support by law.

Equal access to educational opportunity is one of the defining principles of schooling in Australia. As the Internet plays a more important role in the process of schooling, so too does the issues of access for students with disabilities. At the same time, policy related to individuals with disabilities is undergoing a transformation. Lawmakers and administrators are rethinking the concept of ‘access’ in light of the Internet and its importance in education today.

In Australia the Disability Discrimination Act 1992 makes it is unlawful to discriminate against disabled people and applies to educational institutions, as well as private companies and government agencies.

Many educational institutions have already established accessibility guidelines based on the W3C’s Web Accessibility Initiative (WAI). Many institutions have adopted an incrementally staged plan for accessibility, gradually adopting a policy to accommodate a thoughtful training and support program.

Macromedia produces comprehensive support materials for accessibility, including explanations of the guidelines, online courses and templates. Materials provided also offer valuable content for curriculum. The automated Section 508 and W3C accessibility test tool from UsableNet can be used within Dreamweaver to test and educate students. It automatically evaluates Web pages and explains what, why and how a Web page can be changed to incorporate accessibility.

EdNA Authoring Guidelines for Web Accessibility

EdNA Online a directory about education and training in Australia a database of Web-based resources useful for teaching and learning and aims to promote collaboration throughout the Australian education and training sector. Guidelines for the EdNA directory of education and training in Australia:

In this guide you will find the technical guidelines explained in simple English, simple step by step guides and advice, examples of good sites that use a variety of techniques, and good sites that demonstrate how current sites could be made more accessible using simple improvements. A checklist is provided to help you check your web pages before submitting your web pages or web site to EdNA. A glossary of terms used in this guide is available at the end, along with an annotated web site bibliography of sites to visit for more information, and technical assistance. If you are a programmer or web-master, you will find links to advanced technical information in the bibliography.

Option Keys - TAFE NSW

This website has been developed to assist all TAFE online teams in developing online resources and websites which can be easily accessed by all users.

Knowing your students' profiles will help you to understand their needs and come up with websites that fully meet those needs. This includes knowing who they are, how they access the web, what barriers they may face and what adaptive technologies they can use. More than 450,000 people study with TAFE NSW each year. (Figures quoted here come from Operational Statistics Data, TAFE Warehouse on the Web.) These students come from a variety of backgrounds, geographical locations and have a range of different needs. For example, recent enrollments show that about 5 per cent of TAFE students have a disability. Other access barriers can arise for students with difficulty reading, writing and understanding English over 24,000 students (ie 5 per cent) have a disability students living in remote areas When planning your web course you need to do an analysis of the students who are likely to study your course and note the implications this has for your web design. An understanding of the needs of your target audience will help you to tailor your design to meet those needs.

<http://www.oten.edu.au/optionkeys/>

TAFE NSW guidelines give five steps for accessibility:

  1. Plan for Accessibility
  2. Choose Accessible Tools
  3. Follow Design Guidelines
  4. Test for Accessibility
  5. Inform Users of Site's Accessibility

Business Accessibility Solutions


New legal stances on accessibility have already attracted the attention of large corporations and educational institutions throughout Australia and the United States. In Australia the Disability Discrimination Act 1992 covers the private sector. Although Section 508 of the US Federal Rehabilitation Act does not directly affect the private sector, other policy and law providing for equal access for employees or potential employees.

To avoid the need for major redesigns in the future and ensure that primary content is accessible to the widest possible audience, many corporations understand that websites must follow accessibility guidelines from the start of the design process.

Corporations are very similar to Government agencies with external and internal web sites and large Web design workgroups that manage content contributed via multiple sources and people. One of the keys to a successful accessibility plan is helping individuals of different skill sets and experience work together to create an accessible site.

Corporations hoping to provide goods and services via the Web or other information technology should be aware of accessibility standards. Corporations with an understanding of accessibility and the ability to meet the requirements of accessibility have a strong market advantage over those that do not. This advantage is then multiplied many times over as new policies are implemented each day within governments as well as schools, colleges and universities around the globe.

Macromedia offers guidelines for accessibility, templates and third party evaluation and testing/resolution tools that support implementation of a corporate wide accessibility design process.

Highlights of the guide include an introduction Web accessibility design, an overview of accessibility standards, tools for evaluating Website for accessibility and noted resources that can assist in retrofitting websites for full accessibility.

Introduction To Accessible Web Design

One of the greatest obstacles to more universal access to the Web is the lack of awareness on the part of Web designers and developers about how to implement a fully accessible Website. Designers tend to build websites based on their own personal preferences and experience. A designer with a personal preference for visual learning may build a site with graphics and animation, while another designer with a preference for simple text may develop a site that is dense with words and minimal in graphics. Developers also tend to use products they have the greatest familiarity with, rather than those that could provide flexibility and inclusiveness in design for accessibility.

To build fully compliant sites, designers must be aware of their own personal design bias and accessibility standards, but, most importantly, they must develop an expertise with the tools essential for building accessible Web sites.

When considering where to begin when designing an accessible Website UsableNet™, a Macromedia partner, notes two key design elements for building accessible Web sites:

An accessible website implies accessibility for all users, not just people with disabilities. Designing for and implementing accessibility incorporates the basics of good design theory: simplicity of design with ease of use. Designing for Web accessibility should include providing the multiple views essential for each information asset on a Web site.

Choosing and Implementing an Accessibility Standard

Major global standards bodies such as the World Wide Web Consortium (WC3), and the recently enacted U.S. Federal law under Section 508 clearly delineate a set of standards for Web developers to author accessible content. Upon first review these standard seem a bit daunting to those who are new to standards and accessibility they serve as an excellent road map for authoring accessible web content. It will be important for Web developers new to building accessible websites to choose a standard as a guide to retrofitting or authoring new websites for accessibility. The standards not only act as a guide but the best authoring and validation tools in the software industry build tools and resources to check Web content against the standards.

Getting Started: Evaluating Websites Accessibility

Here is a short check list to get started evaluating Websites for accessibility

  1. Select the accessibility standard to conform to W3C priority 1,2,3, and or Section 508

  2. Identify your website and the many digital assets that comprise the Website

  3. Use the Dreamweaver Ultravedev Accessibility Suite (an extension for accessibility is part of the Suite) over your website. The accessibility extension will allow you to choose either Section 508 or W3C priority 1 as the standard to evaluate the Website. Once the accessibility extension has evaluated the website it will produce a report that will locate each portion of the website that needs retrofitting for accessibility.

  4. Retrofit the website for accessibility using both the 508 Accessibility Suite in Dreamweaver as the accessibility extension will note how to fix the problem and the Standards provide examples of techniques as well.

  5. Run the Accessibility extension again this time to confirm and validate the website has been retrofitted for accessibility.

  6. Launch the website to the server

Tools

The Dreamweaver Ultradev Accessibility Suite can be used to retrofit websites for accessibility. Just download the Dreamweaver or UltraDev extension, read the relevant guidelines, and fix as needed. As new pages are developed, create a list of usability rules, based on the 508 or W3C standards, and use the extension to check each page for compliance as the website is edited. Macromedia has partnered with UsableNet and others to assist designers with the tools, training, and support needed to evaluate current sites for compliance and to retrofit existing Websites.

Common Barriers to Web Accessibility

Because many people using the Internet have visual, hearing, cognitive, and mobility impairments, it is critical for Web developers to identify and understand the common barriers that exist for people with disabilities. By understanding these barriers and utilizing Web accessibility techniques developers can add the critical techniques to make Web content accessible.

Here is a short checklist of common barriers:

  1. Images
  2. Multimedia files
  3. Frames
  4. Forms
  5. Tables
  6. Color
  7. Navigation
  8. Plug-ins

Assistive Technology Devices

Many developers are unaware of the assistive devices that persons with disabilities use to access the Internet. One example of an assistive device is-a person with a visual impairment may use a screen reader to listen to the HTML code that comprises a Website.

Those of use who are sighted rely on the graphic visual interface of the browser and rarely think of the HTML code behind the page as significant. People that uses a screen reader to access the Internet are subjected to a wide range of tags with labeling that generally only makes sense the developer who authored the page. For example, developers may tag a list of buttons to key links on a page as button 1, button 2 etc. People with visual impairments rely on Web developers to tag images, button tags and other digital assets with meaningful words that would make sense to anyone just listening to HTML being read.

People with hearing impairments rely on closed captioning for access to video and audio files. Persons with mobility rely on short-cut key strokes and the ability to tab through a Web page as people with mobility impairments many are not able to use a mouse. These are just a few of the elements to consider when making a Website accessible. The National Center for Accessible Media (NCAM) a key Macromedia Partner provides a comprehensive listing of assistive media devices and free tools such as MAGpie to close caption digital media:

Techniques used by Web developers to overcome barriers to Accessibility

In order to make Websites accessible developers may use a host of techniques to overcome common barriers.

Images and Multimedia

It is critical to tag all images and multimedia with meaningful descriptions of the content.

There are three key techniques used to do accomplish this goal.

“ALT tags” embedded in the HTML code can be used to provide descriptions of visuals presented in Web sites. As these tags are the only means for persons using electronic readers (such as JAWS) to glean meaning from the graphic, Flash file, or other multimedia image, it is important to carefully name the ALT tags. Keep in mind that the person will be listening to the ALT tag as a means to understand the image. “Alt-tags” and long descriptions (“LONGDESC”) are critical to persons who are visually impaired: these tags provide essential information needed to navigate the site and they ensure inclusiveness in the design and delivery of information.

A d-link is a hyperlinked letter d (for description) to the right of an image. The letter d is linked to a separate page with a longer description of the image.

A third method, very similar to the use of the d-link, places a caption next to the image and links the caption to the descriptive page. Offering the same functionality as the d-link, using captions is often easier to integrate into a design scheme.

The use of the ALT tag, LONGDESC and d-link are demonstrated in the accessibility templates and case studies available in the Accessibility Solutions CD and downloadable at www.macromedia.com/accessibility.

Tables, Frames and Forms

Tables and frames are both common features found in Websites. You can make these elements accessible by following standards outlined in the W3C and Section 508. Since most screen readers process information on Webpages from left to right, the W3C priority 1 guidelines suggest developers should “create tables that transform gracefully.”

Developers can do this by identifying row and column headers. For example, in HTML, use TD to identify data cells and TH to identify headers. See the WebAIM tutorial for full examples of how to develop accessible tables. http://www.webaim.org/tutorials/tables

Frames pose problems for may users since they compound the common human need to search for an information focal point where to begin. If you must use frames be sure to use a NOFRAMES attribute that leads to an alternate page that list the frames content in an unframed version.

Color

One in ten men are color blind. This represents a large portion of Internet users. When creating accessible Web content be sure to use the follow two tips:

The WebAim tutorial provides clear examples of color contrast and markup examples for meeting accessibility standards: http://www.webaim.org/tutorials/color#2.2

Vischeck http://vischeck.com/ provides a tool that demonstrates a way of showing developers what things look like to someone who is color blind. It can be used on a single image or on a web page, it can also run on your own computer.

Navigation

“People with cognitive, visual, or other disabilities may have a difficult time navigating a complex or confusing Web site. To increase the likelihood that a person will find what they are looking for at a site, Web developers should provide clear and consistent navigation mechanisms, such as, orientation information, navigation bars, a site map, etc.” http://www.webaim.org/tutorials/navigation

Embedded Plugins

Users with disabilities may not be able to access even accessible web sites if Web developers use an imbedded interface that an assistive technology is not able to access.

Plug-ins enable browsers to display a particular file format. Each plug-in requires a distinct strategy for accessibility. Under Section 508 the use of plug-ins must comply with standards for software. Similar to standards for Web content, the software standards also require that the plug-in function without a mouse. The following is an example of a commonly used plug-in and the related issues.

Macromedia Flash Player poses two accessibility issues. First, there needs to be a text description for the content of the Flash movie. Since there is no Alt tag associated with a Flash page element developers need to place an Alt text element elsewhere. One way to create Alt text for Flash content is to use CSS layers. A layer is drawn over the Flash content on page using Draw Layer object in Macromedia Dreamweaver. The alternative text is inside of the layer and the visibility property is set to Hidden. Another way to add Alt text is to add a d-link.

A second accessibility issue is device-independence. The Flash movie must support keyboard-and mouse-based interaction. This may require guidance for novice Flash developers. http://www.webaim.org/tutorials/embedded#8.1

Segregation

For many Web designers, site segregation is a quick solution. This is a method where Web designers provide accessible Web sites by creating a text-only companion site. The text-based site is generally a stripped down version of the full website and may lack such descriptive elements as interactive videos, graphics, combination text and graphic charts and tabular or framed information which may be provided in the full website. But, designers can move beyond this commonly used – and less imaginative -- practice of segregated sites to provide high quality and accessible design. They can create fully integrated Web sites that provide all people with descriptive information about each element (in text and/or audio as appropriate) through the use of alt tags, d tags, and longdesc tags.

Making Rich Media Accessible

Web developers can create fully integrated rich media Websites that provide descriptive information about each element (in text and/or audio as appropriate) through the use of alt tags, d-links, and longdesc tags. Macromedia provides an example of how to implement an integrated rich media site in our rich media template. This template demonstrates how to create accessible Flash movies, and banners, Fireworks buttons, along with Dreamweaver and Ultradev. Additional digital assets such as images, dynamic tables, forms, and audio files are demonstrated as well. This template can be found at www.macromedia.com/accessibility

An accessible site not only provides full access for people with disabilities, but also provides comprehensive access to all users. Designing for and implementing accessibility incorporates the basics of good design theory: simplicity of design with ease of use. Designing for Web accessibility should include providing the multiple views essential for each information asset on a website.

Other Resources for Web Developers

Macromedia also provides an Accessibility Discussion Group to give developers a place to share with other extension users and developers their ideas, opinions, and experiences regarding accessibility issues. Developers can respond to an existing thread, by using the reply section of a thread page, or start a new discussion thread. This discussion is not moderated, but Macromedia reserves the right to delete any irrelevant or obscene postings.

Accessibility Tutorial Examples

Macromedia recognized early the importance of Section 508 and in response to government clients created a step-by-step guide for Web developers to create 508 conformant Web content. The 508 Web Development Guidelines Tutorial provides, point by point, how to conform to the standards using Dreamweaver. You can download the tutorial at: http://www.macromedia.com/macromedia/accessibility/

Here is an example of the priority 1194.22(a) from the html downloadable file:

A text equivalent for every non-text element shall be provided (e.g., via "ALT", "LONGDESC", or in element content.

Explanation

When a user reads or views a web page with a text browser, screen reader, or a browser with images not loading, images are displayed/read as "IMAGE" unless some additional markup is used to describe that image. The lack of use of one of the following techniques make it difficult for users to know what information the image is trying to convey.

The ALT attribute provides a description phrase for each image. Up to 256 characters can be used in this context.

The LONGDESC attribute can be used when an image presents content that requires a more extensive description. This attribute provides a link to a separate page with the description of the content.

The D link can be placed next to an image and linked to another HTML page to provide users of graphical browsers, such as Internet Explorer and Netscape Navigator, a more extensive description of the image.

Examples

ALT Example

University of Wisconsin - Madison's Henry Mall

<img src="/images/henrymall1.gif alt="University of Wisconsin - Madison's Henry Mall">

LONGDESC Example

University of Wisconsin - Madison's Henry Mall

<img src="/images/henrymall1.gif longdesc="henrymall1.htm" alt="University of Wisconsin - Madison's Henry Mall" >

University of Wisconsin - Madison's Henry MallD

<a href="description.html"><img src="/images/henrymall1.gif longdesc="henrymall1.htm" alt="University of Wisconsin - Madison's Henry Mall" ></a>

Adding ALT Text

Entering an ALT attribute to an image in Macromedia Dreamweaver is done through the Image Properties palette. To add an ALT attribute, select the image by clicking on it once. Enter a short description (up to 256 characters) of the image in the Alt box on the Properties Inspector (see picture below). ALT tags should be written in such a way as to provide the user enough information to understand the purpose of the image.

Entering an ALT attribute to an image in Macromedia Dreamweaver

Adding a Long Description

Adding a LONGDESC variable to an image in Macromedia Dreamweaver can be done using one of two methods. The first requires work inside the HTML code. Select the image by clicking once on it. Press F10 to enter the Code Inspector (see picture below). Inside the <IMG> tag, enter the LONGDESC attribute using the line below as a model.

<img src="/images/henrymall1.gif longdesc="henrymall1.htm" alt="University of Wisconsin - Madison's Henry Mall" >

In Code Inspector inside the IMG tag enter the LONGDESC attribute

A second method of entering the long description attribute requires use of an extension called Accessible Image Object from Macromedia Dreamweaver Exchange at http://www.macromedia.com/exchange/dreamweaver/

Before using this method, the extension must first be downloaded and then installed. This extension changes the way images are added. A user is asked for the ALT description and long description URL as the image is added to the page.

Adding Descriptive Link

To add a descriptive link, type the letter D to the right of the image. Select the letter. Enter the name of the HTML file describing the image content in the Link box inside the Text Inspector (see picture below).
