  1. Web Accessibility Math Department -- 2005

  2. What is Web Accessibility?

  3. “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)

  4. 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.

  5. Why is Web Accessibility Important?

  6. 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

  7. 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.

  8. 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.

  9. 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

  10. 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

  11. 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

  12. 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

  13. 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

  14. 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

  15. 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

  16. 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.
