Where We Want to Be
• Achieve Sakai’s Accessibility Mission– The Sakai Accessibility Team is responsible for
ensuring that the Sakai framework and its tools are accessible to persons with disabilities…
– “…access to and use of information and data that is comparable to…members of the public who are not individuals with disabilities.”1
1Section 508 of the Rehabilitation Act of 1973
June 9, 2005 Accessibility: Current Status and 2.xMichael Elledge, University of Michigan 5
Where We Want To Be
• Full implementation of Sakai’s Accessibility Style Guide– Compiled Core and SEPP requirements– Conducted analysis of Sakai 1.0– Built on WCAG 1.0
• A, AA, and selected AAA compliance• “Section 508 Plus”
June 9, 2005 Accessibility: Current Status and 2.xMichael Elledge, University of Michigan 6
Sakai Accessibility Documents
• Documents related to Sakai Accessibility:– Core/SEPP Requirements– Sakai Accessibility Mission Statement– Sakai Accessibility Style Guide– Indiana University Sakai 1.5 Accessibility Testing– Accessibility Team Analysis of CTNG (Sakai 1.0)
• All can be found in the Accessibility section in Confluence:
http://bugs.sakaiproject.org/confluence/display/2ACC/Home
June 9, 2005 Accessibility: Current Status and 2.xMichael Elledge, University of Michigan 7
Where We Want To Be
• Provide a tool that enables:– Heading-based scanning of content and
functional areas– Link-based navigation among tools– Intrasite navigation via accesskeys– Extended descriptions– Tips for Adaptive Technology (AT) users
June 9, 2005 Accessibility: Current Status and 2.xMichael Elledge, University of Michigan 8
Where We Are
• The iFrame Challenge– iFrames in Sakai don’t have self-awareness
• Don’t know about the content they contain• Makes unique page and frame titling difficult
– Can be confusing to AT users• Adds another level of complexity
June 9, 2005 Accessibility: Current Status and 2.xMichael Elledge, University of Michigan 9
Where We Are
• The Portal Challenge– Does not include access elements:
• Skip links, accesskeys• Headings, link titles• Tabindexes
– Result: Navigation not integrated with tools
June 9, 2005 Accessibility: Current Status and 2.xMichael Elledge, University of Michigan 10
Where We Are
• Refactored Sakai Tools– Completed:
• Announcements, assignments, chat, email archive, discussions, home, membership, news, preferences, schedule, web content, page wrapper
– Informed by Accessibility Style Guide:• Alt tags, table headers, headings, form labels, title tags • Tools linearalize, are CSS-based
– Reviewed by JAWS user for usability
June 9, 2005 Accessibility: Current Status and 2.xMichael Elledge, University of Michigan 11
Where We Are
• Minimized the Refresh Problem– Continuous refresh precluded AT user access by
sending AT users to the top of the page– Visible page refreshing has been turned off by default
and coded so that it won’t trip browsers or screen readers
– Will be event based in future, alerting user to new content
June 9, 2005 Accessibility: Current Status and 2.xMichael Elledge, University of Michigan 12
Bottom Line
• Where we are:– Not Section 508 Compliant
• Where we want to be:– Meet Section 508 requirements by next major
release– Exceed Section 508 in future
June 9, 2005 Accessibility: Current Status and 2.xMichael Elledge, University of Michigan 13
How To Get There
• Short Term Goal: Become Section 508 compliant by fall
• Plan:– Resolve portal problems– Finish tool refactoring– Screen tools for Section 508 compliance– Test and tweak tools for usability*
*May be outside of 2005 scope
June 9, 2005 Accessibility: Current Status and 2.xMichael Elledge, University of Michigan 14
How To Get There
• Resources– Indiana University AT Lab– University of Michigan Usability Lab– University of Toronto – AT units at other core institutions
• MIT• Stanford• UC Berkeley• Foothill-DeAnza
June 9, 2005 Accessibility: Current Status and 2.xMichael Elledge, University of Michigan 15
How To Get There
• Resolve Portal Problems– Immediate: Revise existing portal– Fall release: Develop new, non-frame portal
June 9, 2005 Accessibility: Current Status and 2.xMichael Elledge, University of Michigan 16
Where We Want To Be
• Wireframe example– Containing skips, accesskeys, frame titling,
and headings– Demonstrate with JAWS
• JAWS rendering follows
