Getting to Know YouWho are you?Name, job title, organizationYour experience to date with web design/development/content management and accessibilityWhy are you here?What to you hope to gain from this session?6. Accessibility the ability to access the functionality, and possible benefit, of some system or entity.-Wikipedia, Accessibility7. Usability the extent to which a product (e.g., device, service, environment) can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use.-Wikipedia, Accessibility8. Accessibility Fail9. Usability Fail10. Why is Accessibility an Issue?Because the increasingly graphic nature of the Web has made using it more difficult for people with visual disabilities to useBecause Web browsers are too forgiving of bad code(X)HTML doesnt have to be perfect to display correctly to a sighted personBecause library Web pages tend to be home-grown11. Accessibility: Why Does It Matter?The American Foundation for the Blind estimates that:10 million people in the US are blind or visually impaired1.3 million people are legally blindPeople with learning and physical disabilities use screen readers as wellLegal implications: AFB vs. TargetUniversal Design: writing good code is good practice, and makes it more accessible to all12. Excuses, ExcusesWere not legally obligated to be accessible.Its too hard to create accessible sites.We dont have (m)any users with disabilities.Our vendors dont; why should we?Screen reader technology will catch up.13.

WCAG 2.0: Whats New?List of 14 guidelines restructured into an outline of 4 principlesNot as specific as checkpoint format of WCAG 1.0Priorities 1-3 replaced with conformance levels A-AAA Note: well be reviewing Level A onlyMet with criticism from developers16. WCAG 2.0 Principles 1-2Principle 1: PerceivableInformation and user interface components must be presentable to users in ways they can perceive.Principle 2: OperableUser interface components and navigation must be operable.17. WCAG 2.0 Principles 3-4Principle 3: UnderstandableInformation and the operation of user interface must be understandable.Principle 4: RobustContent must be robust enough that it can be interpreted reliably by a wide variety of user agents, including assistive technologies.18. Principle 1, Guideline 1.1Text alternativesProvide text alternatives for any non-text content so that it can be changed into other forms people need, such as large print, braille, speech, symbols or simpler language. 19. 1.1.1: Non-text ContentAll non-text content that is presented to the user has a text alternative that serves the equivalent purpose.
