Introduction Marilyn Greenwell Web Accessibility Coordinator, University of Louisville since March 2006 Webmaster for whas11.com (5 years) Webmaster for Clear Channel Louisville’s 8 radio stations and two news networks (5 years) I thrive on technology and computer-related knowledge I am a self-proclaimed “GEEK”

    4. Agenda Web Accessibility What is it? What are the types of disabilities? Why is it important to you as a provider? What can you do to comply?

    7. Wikipedia says: Web accessibility refers to the practice of making websites usable by people of all abilities and disabilities. When sites are correctly designed, developed and edited, all users can have equal access to information and functionality.

    8. OK… so… WHAT IS IT? Web accessibility is designing with accessibility in mind. It is creating websites and other electronic media that is free of barriers to those who use assistive technology devices or alternative measures to access and navigate electronic information.

    10. Blindness or Low Vision Vision Issues include Low Vision Have some vision but need magnification and good contrast Blindness Have no vision, requires audio stimulus or screen readers Color Deficiency (color blindness) Have visual abilities, but cannot see some color spectrums. Requires good contrasts.

    11. Hearing Loss or Deafness Hearing Issues include Deafness Unable to recognize conversational speech through hearing Hard of Hearing Some loss of hearing function but still able to use hearing for communication Often requires amplification .

    12. Motor Skill Impairment Motor Skills Issues include many conditions that limit one’s ability to use conventional mouse and/or keyboard Common causes include arthritis, Parkinson’s disease, various forms of muscular dystrophy, repetitive strain, stroke, spinal cord injury, etc. For many with motor skill impairments, assistive technology enables them to navigate your website. Best suggestion is to make sure your site can be easily navigated with keyboard

    14. Cognitive Issues Cognitive Issues include Learning Difficulties Dyslexia Attention Deficit Memory Difficulties Easily the least understood of common issues Estimated to have affected more people than all other categories combined Research is showing that Cognitive issues are quickly becoming one of the largest affected groups Recommendations are slowly appearing

    15. Photosensitive Epilepsy

    16. Go to maps.google.com Search for your home address Exercise 1

    17. Exercise #2 Let’s watch a portion of this video. Pay close attention, there will be a short quiz afterwards. http://youtube.com/univoflouisville Now, watch it in an alternative version http://www.overstream.net/view.php?oid=ndtluvivmbmr Did the alternative version make any difference for you?

    19. Let’s state the obvious It’s The Law Rehabilitation Act Section 504 Section 508 Americans with Disabilities Act Kentucky Statutes KRS 61.6980 – 61.988

    20. So What? Nielsen estimates that about 90% of business-oriented web sites suffer from usability issues. A recent Harris Poll found that people with disabilities spend twice as much time on the Internet as people without disabilities. If users with or without disabilities cannot use a site, so what?

    21. Why is Web Accessibility Important to YOU as a provider? According to the World Wide Web Accessibility Initiative, providers have the following benefits: Increase Market Share and Audience Reach How many does your site exclude? Improve Efficiency Where do search engines rank your site? 3. Demonstrate Social Responsibility Is it really going to hurt you to do the right thing? 4. Reduces Legal Liability Are you ready for a lawsuit?

    22. OUCH! That hurts! Some are learning the hard way that they must comply with Federal and State laws and guidelines.

    24. Universal Design “The design of products and environments to be usable by all people, to the greatest extent possible, without the need for adaptation or specialized design” -- Ron Mace, founder of the Center for Universal Design at NC State University

    25. Universal Design Adapts to the full range of user ability and preference Regardless of skill, knowledge or concentration level, is easy to understand and use Provides essential information regardless of sensory abilities Minimizes effects of unintended actions allows easy recovery Considers physical requirements and does not fatigue user – regardless of body size, posture, or mobility Appealing and useful to all users

    26. W3C - 10 Quick Tips The links in the Quick Tips below mostly go to the techniques documents that provide implementation guidance - including explanations, strategies, and detailed markup examples. Images & animations: Use the alt attribute to describe the function of each visual. Image maps. Use the client-side map and text for hotspots. Multimedia. Provide captioning and transcripts of audio, and descriptions of video. Hypertext links. Use text that makes sense when read out of context. For example, avoid "click here." Page organization. Use headings, lists, and consistent structure. Use CSS for layout and style where possible. Graphs & charts. Summarize or use the longdesc attribute. Scripts, applets, & plug-ins. Provide alternative content in case active features are inaccessible or unsupported. Frames. Use the noframes element and meaningful titles. Tables. Make line-by-line reading sensible. Summarize. Check your work. Validate. Use tools, checklist, and guidelines at http://www.w3.org/TR/WCAG http://www.w3.org/WAI/quicktips/

    27. Follow WCAG Guidelines WCAG Version 1 Priorities Each checkpoint has a priority level assigned by the Working Group based on the checkpoint's impact on accessibility. [Priority 1] A Web content developer must satisfy this checkpoint. [Priority 2] A Web content developer should satisfy this checkpoint. [Priority 3] A Web content developer may address this checkpoint. http://www.w3.org/TR/WCAG10/full-checklist.html

    28. 5-minute Quick Check Disable or turn off images in your browser Disable or turn off support for JavaScript Tab through the page, try navigating without a mouse Increase the font size by typing Ctrl+ or using the browser Disable/turn off support for CSS If you have tables on your page, linearize Look at site in different browsers and check for consistency.
