  2. Accessibility involves two key issues first, how users with disabilities access electronic information second, how web content designers and developers enable web pages to function with assistive devices used by individuals with disabilities. What is Accessibility?

  3. Section 508 of the Rehabilitation Act of 1973, as amended (29 U.S.C. 794d). requires private or federal agency to provide individuals with disabilities, who are members of the public to have access to the use of information and data that is comparable to that provided to those who are not individuals with disabilities, unless an undue burden would be imposed on the agency. The Disability Act

  4. Report has shown 19.6% of the U.S. population as having some sort of disability. Within that group are individuals with visual, hearing, cognitive, and motor impairments. Each category includes a much wider range of conditions. For example, visual impair include limited vision, color blindness, and blindness.

  5. The Focus of this presentation will be on the Vision Impaired

  6. According to the (ADA) one estimate approximately 10 million people in the Unites States are blind or visually impaired. Over the next 30 years, the number of adults with vision impaired is suppose to double. There are three types Blindness Low-vision Color blindness What is Vision Impaired?

  7. The operating systems were not designed for the blind or physically impaired. These applications were created for users that could; read and react to text and images displayed on the screen. Type on a standard keyboad. Select text, pictures, and other information using a mouse. Begining of the operation system

  8. If a person was unable to perform one of those tasks listed they found themselves to be unable to use many computer applications. Continue

  9. In other to solve some of these problems software vendors created products and software which helped people who could not performed one of the four basic tasks to use common computer applications. Begining of Acessibility

  10. Users with disabilities frequently rely on hardware and software to access web content range from screen readers to touch screens and head pointers. Assistive technologies They most likely use the same computer as someone who has a normal vision.

  11. Screen readers enable users to hear, rather than read, the contents of a web page; however, a screen reader can read only text, not images or animations. Two types 1. JAWS from Freedom Scientific 2. Window-Eyes from GW Micro. Software

  12. 2. Screen magnification, software, which allows low-vision computer users to more easily read portions of the screen. Continue

  13. Continue 3. Braille display is a tactile device that raises or lowers dot patterns on command from the computer.

  14. The browser most likely to be used is Microsoft Internet Explorer. Other browsing techniques are possible, like the use of Lynx (a text-only browser written originally to run under Unix to browsing packages such as IBM's Home Page Reader, which generate their own speech. A small group uses Macintosh computer equipped with the appropriate screen access software, but the majority of the users will be found with a personal computer running Windows. Which is easier to translate information on the screen. When entering a web page they check out the hypertext links that are on the page. This is usually done by jumping from link to link with the Tab key; the screen access software automatically reads the highlighted text as the focus moves from link to link. Surfing the web

  15. If the highlighted text is something like “How to Contact Us” or “Visit Your Shopping Cart,” the blind user will be able to make some sense out of the link. If, however, the highlighted text is “Click Here,” or “Here,” it will be difficult if not impossible for the blind user to interpret the meaning of the link without using a different navigation strategy.

  16. Improvement have been made with screen access software/browser combinations, today some of the web surfer problem for the a blind have improved. They do not have to explore a web page line by line. However, being forced to examine every detail of a web page just to learn the meaning of a hypertext link is a time-consuming process which, ideally, should be avoided. Present software

  17. Overview There are many different types of software available for the vision impaired. Screen Readers software Screen Magnifiers Refreshable Braille Displays
