Transcript

  • 1. Accessible web applica,ons Chris,an Heilmann ‐ European Accessibility Forum, Frankfurt/Main, 27/03/09
  • 2. A lot of web applica,ons  are not accessible.
  • 3. There are several  reasons for this.
  • 4. Changing exis,ng web  applica,ons is possible,  but a pain.
  • 5. In a lot of cases,  maintainers of web apps  are simply not aware of  the issues they cause.
  • 6. So we need to  find and tell  people the real  informa,on. hJp://scrip,ngenabled.org/presenta,ons/
  • 7. And then show in easy  proof of concepts that  the change can happen  and have an impact.
  • 8. This can have a massive  impact.

  • 12. Do you need to be a  coding wizard to show  how changes can be  made?

  • 15. This can help you with an    exis,ng app, but what  about new ones?
  • 16. What we should  concentrate on is how do  we create new apps in a  way that is accessible.
  • 17. Here are some ideas...
  • 18. Simplicity
  • 19. List of links? ARIA enabled tab control?
  • 20. How about radio group?
  • 21. Data table? Grid control?
  • 22. What about a  heading structure  with lists and  clever CSS?
  • 23. Excellence

  • 25. Re‐use
  • 26. Web applica,ons can be  built using exis,ng lego  bricks of controls.
  • 27. We’ve already created all  of these bricks in  libraries: Dojo, YUI,  jQuery...
  • 28. And now more and more  of those get ARIA  support for accessibility.
  • 29. hJp://yuiblog.com/blog/category/accessibility/
  • 30. And we share our  findings and ideas.
  • 31. All we want is for you to  make it worth our while  by building upon our  efforts.
