  1. Making the Web Accessible to All

  2. What is it? Web accessibility means that anybody, including people with disabilities, can perceive, understand, navigate, and interact with the Web. This also means they will be able to successfully contribute to the Web as well. Web accessibility also benefits others, including older people with changing abilities due to aging. Web accessibility encompasses all disabilities that affect access to the Web, including visual, auditory, physical, speech, cognitive, and neurological disabilities.

  3. Why is it Important? The Web is an increasingly important resource in many aspects of life: education, employment, government, commerce, health care, recreation, and more. It is essential that the Web be accessible in order to provide equalaccess and equalopportunity to people with disabilities. An accessible Web can also help people with disabilities more actively participate in society.

  4. Why is it Important Cont… The Web offers the possibility of unprecedented access to information and interaction for many people with disabilities. That is, the accessibility barriers to print, audio, and visual media can be much more easily overcome through Web technologies. Another important consideration for organizations is that Web accessibility is required by laws and policies in some cases.

  5. Making the Web Accessible Much of the focus on Web accessibility has been on the responsibilities of Web developers. However, web software also has a vital role in Web accessibility. Software needs to help developers produce and evaluate accessible Web sites, and be usable by people with disabilities. One of the roles of the Web Accessibility Initiative is to develop guidelines and techniques that describe accessibility solutions for Web software and Web developers.

  6. Web Accessibility Cont… The WAI guidelines are considered the international standard for Web accessibility.

  7. Making Your Site Accessible Making a Web site accessible can be simple or complex. Depending on many factors such as the type of content, size and complexity of the site, and the development tools and environment. Many accessibility features are easily implemented if they are planned from the beginning of Web site development or redesign. Fixing inaccessible Web sites can require significant effort, especially when not originally "coded" properly with standard XHTML, and sites with certain types of content such as multimedia. Make sure to plan ahead.

  8. Evaluating Accessibility of a Site When developing or redesigning a site, evaluating accessibility early and throughout the development process can identify accessibility problems early when it is easier to address them. Simple techniques such as changing settings in a browser can determine if a Web page meets some accessibility guidelines. A comprehensive evaluation to determine if a site meets all accessibility guidelines is much more complex. There are evaluation tools that help with evaluation. However, no tool alone can determine if a site meets accessibility guidelines.

  9. Evaluating Continued… Knowledgeable human evaluations are required to best determine if a site is accessible or not. There are web sites that can do a basic scan of your site to see if it is compatible or where you might have problems. One site to look into is: Section508 Also, if you wish to learn the standard guidelines, a good source of reference is: W3.org Evaluation You want to make sure no one is excluded from accessing your site, so make sure it is fully compatible.

  10. Things to Look Out For Here are a few things to watch out for when evaluating your own site: Flickering- This should be avoided if the flicker frequency is greater than 2 Hz and lower than 55 Hz. Interpretation- When a web page requires that an applet, plug-in or other application be present on the client system to interpret page content, the page must provide a link to a plug-in or applet. Script- When pages utilize scripting languages to display content, or to create interface elements, the information provided by the script shall be identified with functional text that can be read by assistive technology.

  11. Now it’s Your Turn Check your web site and see if you can locate any problems you may run into with offering accessibility to all!!!
