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

Become familiar with alternate database access: Text only
Become familiar with alternate database access: Visual search
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
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
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:
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
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
