Web Accessibility
Web accessibility ensures that all individuals, regardless of disability, can access and understand online information. This principle aligns with architectural accessibility, where buildings are designed for all users. Federal laws like the ADA and Section 504 emphasize the need for accessible websites. Statistics show that millions of Americans have disabilities, and the internet significantly enhances their lives. Tools like screen readers illustrate the importance of accessible design. As we work towards full compliance, resources and education for web designers are essential.

Web Accessibility Math Department -- 2005
“When a website is accessible, anyone browsing the site should be able to gain a complete understanding of the information presented on the site as well as have an undiminished ability to interact with the site.” (http://www.parsons.lsi.ukans.edu/media/smills/WebAccess/int01/02int01.htm) • “The power of the web is in its universality. Access by everyone regardless of disability is an essential aspect.” (Tim Berners-Lee, W3C Director)
Compare Web Accessibility with Architectural Accessibility: Today, buildings are designed to be accessible for all users and older buildings are being renovated to meet this requirement. This same process is taking place in the Computer / Internet Environment.
Federal Laws - (ADA, Section 504) • http://www.arizona.edu/uaweb/accessible/why.php • Section 504 of the Rehabilitation Act (1973) • Americans with Disabilities Act (1990) • 1996 Department of Justice Statement – accessibility of Websites falls under the ADA • UA statement regarding ADA / 504
Section 508 • In 1998, Congress amended the Rehabilitation Act to require Federal agencies to make their electronic and information technology accessible to people with disabilities. Section 508 went into effect in June, 2001. • Under Section 508 (29 U.S.C. ‘ 794d), agencies must give disabled employees and members of the public access to information that is comparable to the access available to others.
Some Statistics…. • Approximately 54 million Americans have a disability • The Internet is a major source of information. If the materials are inaccessible to those with disabilities, a significant number of Internet users are unable to have the same access as non-disabled individuals.
Harris Poll (June, 2000) • Studied the impact of the Internet for individuals with disabilities. • Findings: • Adults with disabilities spend twice as much time online (20 hours/week compared to 10 hours/week) • 48% of adults with disabilities, compared to 27% of those without a disability say the Internet has significantly improved their lives. • Individuals with disabilities under the age of 30 use the Internet for 25 hours a week versus 8 hours a week by young people without disabilities
Demonstration of JAWS • JAWS is a screen reader program used by the visually impaired to access the computer. • This demonstration quickly shows the importance of an accessible website for individuals with disabilities. Inaccessible page: • http://drc.arizona.edu/webaccess/inaccessible.html Versus an accessible site: • http://drc.arizona.edu/webaccess/accessible.html
Making Your Site Accessible • http://www.arizona.edu/uaweb/accessible/accessible.php • Text Equivalents: A text equivalent for every non-text element shall be provided for every image within the web site. (Alt Tags, Longdesc or within text element) Ex: http://www.webaim.org/uofa/ • Color: Color coding shall not be used as the only means of conveying information. The contrast between colors used should be distinct. Ex: http://www.webaim.org/uofa/faculty.htm
Hyperlink Titles: The titles for each hyperlink must be meaningful. Titles like 'Click Here' can cause problems. • Tables: When Tables are used for tabular data, identify column and row headers and associate data with appropriate heading labels. Ex: http://www.webaim.org/uofa/classchanges.htm • Skip Navigation: When providing a long list of navigational links, provide a way for your users to skip over the list. Ex: http://www.webaim.org/uofa/contact.htm
Forms: Form elements will be tagged with the label attribute. Contact information will be provided on each page with a form.Ex: http://www.webaim.org/uofa/library.htm • Scripts / Applets / Plug-ins: Provide contact information on each page with a script, applet, or plug-in so that users can ask questions or request the information in an alternative format.QT Ex: http://www.webaim.org/uofa/history.htmQT Ex: Manhole CoversPDF Ex: Inaccessible PDF
Other Examples: • Flash: http://www.webaim.org/uofa/alumni.htm • Scrolling Text: http://www.webaim.org/uofa/java/news.htm • Refreshing Pages: http://www.webaim.org/uofa/todo.htm
Web Validation Tools • HiSoftware - http://www.hisoftware.com/Ex: http://drc.arizona.edu/access/inaccess/report_fndx.htm • Wave – http://www.wave.webaim.org/index.jsp • Bobby – http://bobby.watchfire.com/ • A-Prompt - http://aprompt.snow.utoronto.ca/ • Color Contrast - http://www.vischeck.com/ • List of different validation toolshttp://uaweb.arizona.edu/resources/validation.shtml
Achieving 100% Website accessibility will not occur overnight. The UA recognizes that this is a process that will take time and require the education of, and support from, Web designers across the campus.
