  18. Web Barriers • Web Design Historically Has Not Included Accessible Design for Persons with Disabilities • Web Developers have Lacked Training, Tools & Resources to Design Accessibly; Web Tools Would Break Accessibility • Governments & Businesses Had No Incentive to Address Accessible Design

  19. Web Barriers An Inaccessible Web: • Prevents Screen Reader Software from Reading Text Out Loud to Persons who are Blind or Have Specific Learning Disabilities • Can be a Barrier for People with Busy Eyes, Or Work in a Dark Room Or Have a Slow Modem

  20. Screen Reader Resource Six Minute Video Clip of Neal Ewers, a Blind Software Engineer, Using a Screen Reader http://www.doit.wisc.edu/accessibility/video/intro.asp

  21. Web Barriers An Inaccessible Web: • Images that Contain Content: Pictures, Charts, Graphs • PDF Documents • Online Forms Missing Labels

  22. Accessibility Solution • Images-Pictures: Add “Alt” attributes or Alternative Text • Images-Charts/Graphs: Add Link that Describes the Chart/Graph • PDF Documents: Tag the PDF for Structure OR Also Post an Accessible Format • Online Forms: Techniques for W3C Web Content Accessibility Guidelines 1.0 www.w3.org/TR/WAI-WEBCONTENT-TECHS/

  23. Web Barriers An Inaccessible Web: • People with Mobility Disabilities Need Keyboard Access when They Cannot Use a Mouse • People who have Busy Hands, Or Limited Dexterity Or No Hands Available

  24. Accessibility Solution An Accessible Web: • Provides Logical Linear Tab Order • Provides Device Independence so that Mouse is Not Required for Operation • Exposes Content for All Devices • Implements Techniques for W3C WCAG 1.0 or 2.0

  25. Web Barriers An Inaccessible Web: • People Using Speech Technology Input Cannot Access Web Content • People with Low Vision Cannot Increase Web Text Size

  29. Accessibility Solution An Accessible Web: • Uses Captioning Feature for Audio on YouTube Videos • Allows User to Turn Captioning On/Off • See www.youtube.com/t/captions_about

  30. Web Barriers • Online Conferencing Applications • Many Rely on Audio Only with no text alternative for People with Speech or Hearing Loss • Many Do not Work with Assistive Computer Technologies • Some allow for Text Alternative of Captioning Services, but Fail to Provide Ability to Resize Captioning Window

  31. Accessibility Solution • Online Conferencing Applications • Should be compatible with Captioning Services • Should work with Assistive Technologies (AT) such as screen readers, screen magnifiers & speech recognition systems • Example of Accessible Online Conferencing Application at www.onlineconferencingsystems.com

  32. Accessibility Solution • Web Based Captioning Services • Enables people with hearing and speech disabilities to follow online what is being said during a teleconference meeting or a conference • User can go online and read the text of the audio stream onto a website; website allows chat text for questions and comments • Example of Service Provider: CaptionFirst www.captionfirst.com
