Web Accessibility Initiatives/W3C
• Access has been a concern for the web since its beginning
• In 1997 the World Wide Web Consortium (W3C) was formed to watch over the Internet
• A spin off of W3C called Web Accessibility Initiative was charged to develop accessibility guidelines
WC3 Guidelines• Images & animations - use alt attribute to
describe visuals
• Image maps - use client MAP & text for hotspots
• Multimedia - provide captioning, transcripts of audio, descriptions of video, and accessible versions
More WC3• Hypertext links - use text that makes sense
if read out of context
• Pages - use headings, list, and use CSS (cascading style sheets) for layout when possible
• Scripts, applets, plug-ins - provide alternative content in case features can’t be supported
Last of WC3
• Frames - label with the title or name attribute
• Check your work - validate the HTML, use evaluation tools and text-only browsers to verify accessibility
– Section 508 mimics these guidelines
Web Validation Information
• Web validation can be done by following guidelines for Section 508, WAI, or using a web validation software such as Bobby (2002)
• Bobby will view your URLs and assist your web validation efforts.

Who Benefits from Accessible Technology?
• According to a recent Microsoft study the majority of computer users will benefit– People with mild difficulties (37%)– People with severe difficulties (25%)– People with no difficulties to minimum
difficulties least likely to benefit (37%)– Identifying Who is Likely to Benefit from the Use of Accessible Technology
• Retrieved May 10, 2004 from http:www.microsoft.com/enable/research
(EASI) Retrieved May 10, 2004• “Today's distributed computer environment means that
providing support for the technology needs of students and professionals with disabilities is a global responsibility. It requires extensive planning and cooperation across several departments. "If it takes a village to raise a child, then, it takes the global commitment to support the adaptive technology needs of students and professionals with disabilities. It is no longer the sole province of the computer. It cannot be relegated to the disabled student office either. Seamless service requires campus-wide cooperation.”
