  2. The Web Accessibility Puzzle…

  3. … has many pieces • Web developers must understand and practice accessibility • Web authoring tools must make it possible (and easy) to create accessible content • Assistive technologies and browsers must support accessibility standards • Policy makers must demand accessibility (and policies must be enforced)

  4. Another important piece…

  5. Just Do It! Make it accessible ourselves

  6. Crowdsourcing The act of outsourcing tasks, traditionally performed by an employee or contractor, to an undefined, large group of people or community (a crowd), through an open call. -Wikipedia, http://en.wikipedia.org/wiki/Crowdsourcing

  7. Success Story: TED Open Translation Project As of November 19, 2010: • 4192 volunteers • 79 languages • 12,815 subtitles

  8. TED’s Tool: DotSub.com

  9. UniversalSubtitles.com • 3097 videos captioned • Download in various caption formats, including .SRT for uploading to YouTube, or • Embed a YouTube player on any web page with captions uploading captions to YouTube not required) • Example

  11. Serotek C-SAW • "Community-Supported Accessible Web“ • http://help.samobile.net/C-SAW.html • Requires a subscription to the System Access Mobile Network: http://help.samobile.net/Intro.html • Can be accessed through System Access To Go, which is free: http://www.satogo.com

  12. How C-SAW Works • On an inaccessible image, use Alt+L to label it with alternate text • On an inaccessible form field, use Alt+L to add a label • Insert + S stores your labels to a master database, available to all users

  13. Similar, Past Efforts • Web Visum • http://webvisum.com/ • Firefox plug-in • Community driven tagging and page enhancements. • Automated and instant CAPTCHA image solving • IBM Social Accessibility Project • http://services.alphaworks.ibm.com/socialaccessibility • Provided a tool to facilitate collaboration between “screen reader users” and “volunteers” • Included rewards for volunteers (e.g., rankings)

  15. Greasemonkey • Firefox extension that allows users to run scripts that modify HTML web page content every time a specified page is loaded • http://wiki.greasespot.net • User script repository: userscripts.org • Scripts tagged “accessibility”: http://userscripts.org/tags/accessibility • My scripts: http://terrillthompson.com/gmscripts/

  16. What Can We Do With Greasemonkey? • Add alt to images • Add labels and fieldsets to forms • Add headings • Add ARIA landmarks • Add other ARIA markup • Add custom HTML controls for inaccessible video players (APIs permitting) • Rewrite inaccessible dynamic menus to make them accessible • Etc….
