Known accessibility issues

Sakai contains some accessibility issues yet to be resolved, for some of which there are workarounds:

• JavaScript must be enabled for Sakai to work properly.

• Tool headings are often redundant due to separate page title and content frames. This can be confusing to users of adaptive technology, especially users of screen readers.

• When using Internet Explorer, pressing the up or down keys in some unopened drop-down menus will automatically select the next item and reload the page. To prevent this, first press the Alt-up arrow or Alt-down arrow key to open the menu, and then use the arrow keys to explore the choices.

• The WYSIWYG editor used to edit rich text within Sakai has many accessibility issues. In many cases, workarounds are available. For instance, instructors can allow students to submit assignments as attachments.

• Sakai does not work well with the built-in Microsoft Windows High Contrast display mode. We recommend using the page zoom features in the browser or a third-party screen magnifier (like AiSquared's ZoomText or Freedom Scientific's MAGic screen magnifiers).

Notify the Sakai Accessibility Team Lead at  brichwin@indiana.edu  if you find other problems. Use the subject line "Sakai Accessibility Issues".

General tips and tricks for navigation

Here are some tips for navigating:

Accesskeys

Accesskeys follow the UK e-commerce standards wherever possible, and are mnemonic otherwise. If an Accesskey is available for a given link or button, the accesskey will be announced by a screen reader when that link or button receives focus. To invoke Accesskeys:

• In Internet Explorer, use Alt plus the indicated letter or number.
• In Firefox for Windows, use Alt-Shift plus the indicated letter or number.
• In Safari or Firefox for Mac OS X, use Ctrl plus the indicated letter or number.

• Global accesskeysAccesskeys available throughout the application include:
  • Help tool: Accesskey-6
  • Skip to content: Accesskey-c
  • Skip to tools list: Accesskey-l
  • Skip to worksites: Accesskey-w
• Tool-specific accesskeysAccesskeys are available for most form-based tools.
  • Delete, remove, or cancel: Accesskey-x
  • Edit or revise: Accesskey-e
  • Refresh: Accesskey-u
  • Save: Accesskey-s
  • View or preview: Accesskey-v

Miscellaneous navigation tips for non-mouse users

• You can avoid having to tab through all the navigation and move the focus to tool content with Accesskey-c.

• If you get lost, press Accesskey-c to return the focus to the top of the selected tool.

• If you get stuck in the WYSIWYG editor, and need to get past it, use Accesskey-w to return focus to the worksites list, and then press Shift-Tab repeatedly till focus wraps around to the bottom of the page. Continue pressing Shift-Tab as needed to reach the desired control.

• Browsers differ in how they handle keyboard access. If a certain feature doesn't work in a given browser, try another browser.

Additional navigation tips for screen-reader users

• Use headings to navigate. The major sections of each page, such as the worksites list, the tools list, and content within tools, are marked with headings and well structured hierarchically using heading levels (level 1, level 2, level 3, etc.). Pressing  h  moves to the next heading. Pressing Shift-h moves to the previous heading.

• To get a list of all the headings on a page:

• • In JAWS, press Insert-F6 for a list, and then scroll using the up and down arrows.
  • In Window-Eyes, press Insert-Tab, Alt-h, Alt-s, and then scroll using the up and down arrows.
• To go to the bottom buttons (e.g., Cancel) on a page:

• • In JAWS, press Insert-F5 to open the forms list dialog. Then, press Ctrl-End .
  • In Window-Eyes, press Insert-Tab to open the page navigation dialog, Alt-c to list controls, Alt-s to go to the list, and then press End .
• To have the page contents read again:

• • In JAWS, press Insert-down arrow.
  • In Window-Eyes, press Ctrl-Home , and then press Ctrl-Shift-r .

Accessibility compliance

The continuing objective of developers is to make the application compliant with Section 508 and WCAG 2.0 Level A and AA Success Criteria, and as usable as possible for persons using adaptive technology. Most tools follow W3C accessibility guidelines for headings, forms, tables, links, and images, but do not include non-script alternatives to JavaScript, or user messages for pop-ups or completed actions. Tools following most guidelines include:

• Announcements
• Assignments
• Chat Room
• Gradebook
• Home
• My Workspace--Membership
• My Workspace--Preferences
• News
• Permissions
• Resources
• Site Info
• Syllabus
• Tests & Quizzes
• Web Content
• Worksite Setup

Some tools are being worked on to improve their accessibility. These include the following:

• Administrative Tools (Users, Aliases, Sites, Realms, M, On-Line, Memory, Site Archive)
• Drop Box
• Forums
• My Workspace--Profile
• Podcasts
• Roster
• Schedule
• Section Info
• Wiki

Sakai has been tested with current versions of JAWS using both Internet Explorer and Firefox. Compliance has also been evaluated using manual code inspection, the Firefox Accessibility Extension add-on, the WAVE Web Accessibility Evaluation tool, and W3C Validator in order to continually improve accessibility.
