  8. In mid-70s, Ray Kurzweil saw the potential of new technologies to assist people with disabilities This prototype Kurzweil machine combined optical character reader technology with computer synthesized speech Machine reads books aloud to individuals with visual impairments What has changed?Technology

  9. Technology can now be used by people with disabilities to do things that they could never do before Technology can also become a barrier when people are trying to live independent and meaningful lives What has changed?Technology

  10. What has changed?Expectations • Students in K-12 education: least restrictive environment • Individual Education Program (IEP) and testing accommodations • Assistive Technologies • Students encouraged to be independent • Want to be “like everyone else”

  11. What has changed?Disabilities • Original • Speech, Vision, Hearing impairments • Mental Retardation • Wheelchair User (orthopedic) • Now added • LD (Learning Disability) • EBD (Emotional Behavioral Disability) • ADD (Attention Deficient Disorder) • Autism • Many Disabilities are “invisible”

  26. Speech Recognition http://content.sphsc.washington.edu/public/image/553.wmv

  27. Speech Synthesizer http://content.sphsc.washington.edu/public/image/774.wmv

  28. Assistive Technologies • Computers require power • Cost can be high • Steep learning curve • Need own computers to use

  29. Activity 2: Online checkers for web accessibility Links available at www.EduKateTodd.com/check

  30. A few solutions A solution for one person can become a problem for another person

  31. Wisconsin Department of Natural Resources http://dnr.wi.gov/WWWAccessibilityNotice.html U.S. Army Redstone Test Center http://www.rttc.army.mil/navtips.htm Skokie Public Library http://www.skokielibrary.info/s_kids/kd_COI/index.asp Accessibility Notices

  32. Become familiar with alternate database access: Text only

  33. Become familiar with alternate database access: Text only

  34. Become familiar with alternate database access: Visual search

  35. Become familiar with alternate database access: Visual search

  36. Web page design • HTML, the language used for web pages, allows each browser to format information • Web designers and graphic designers want to control the visual • They use tables to hold elements in place on a page • They convert text to graphic representation so that the font will always look the same

  37. HTML/Dreamweaver • To make web pages accessible: • Use text, not graphic representation of text • Use alt= tag when inserting an image • Place directions before boxes and forms rather than below them • Think twice before using tables for formatting • Accept the fact that you cannot control everything on the web • View HTML Do’s and Don’ts at http://infopeople.org/resources/htmltips.html

  38. Flash • Don’t rely on colors for control choices • Put text on buttons • Label complex controls such as sliders or dials • Best Practices for Accessible Flash Design link at: http://www.adobe.com/resources/accessibility/best_practices/bp_fp.html

  39. Adobe Acrobat Reader (.pdf) • Documents that are scanned and saved as “image only” cannot be read by a screen reader such as JAWS • Adobe version 7 has a feature that will use OCR technology to convert the scanned document to readable text • You can find the Adobe manual on creating accessible PDFs at http://www.adobe.com/accessibility/index.html

  40. Testing Web Sites • Use free web site check tools • Web designers should own testing products such as Bobby • All web sites should have user tests • Users should include people with disabilities • When it comes to accessibility, the solution for each individual may be unique
