Talk about today 1. What is WCAG - along with Who, Where, When, Why, and How 2. What WCAG 2 gives you - Applies to more advanced technologies Clearer criteria Flexible, adaptable Practical implementation examples and info 3. Making accessibility easier & better - Authoring tools and browsers 4. What you can do now

We won’t cover § The basics of Web accessibility and WCAG 1. 0 § The business case § Policies, laws, § … and such Will provide resources for these.

WCAG = Web Content Accessibility Guidelines § International standard § Applies to Web pages, sites, applications § For: • Web developers and designers, • Authoring tool and evaluation tool developers, and • Others who need a technical standard. • (not for novices)

Who develops WCAG § The standards-making body for the Web § International, multi-stakeholder § Formal process

How WCAG is developed, Stage 1 WCAG Working Group development WCAG Working Draft Community|Public review and comment

Getting better with age For example, clearer with less jargon § 2006 Draft: 4. 1. 1 Web units or authored components can be parsed unambiguously, and the relationships in the resulting data structure also unambiguous. § 2007 draft: 4. 1. 1 Parsing: Content implemented using markup languages has elements with complete start and end tags, except as allowed by their specifications, and are nested according to their specifications.

Getting better with age § Note new and improved documents: • WCAG 2 FAQ • WCAG 2. 0 Quick Reference • Summary of Issues, Revisions, and Rationales for Changes to WCAG 2. 0 2006 Last Call Draft

When will WCAG 2. 0 be completed?

WCAG 1. 0 WCAG 2. 0 WD § Principles § Guidelines

WCAG 1. 0 WCAG 2. 0 WD § Guidelines § Principles: POUR 1. Perceivable 2. Operable 3. Understandable 4. Robust § Guidelines

What WCAG 2 gives you § Easier to understand success, that is: more precisely testable (do still need human)

WCAG 1. 0 WCAG 2. 0 WD § Principles: P-O-U-R § Guidelines • Checkpoints Priority 1, 2, 3 § Guidelines • Success Criteria Level A, AAA

§ WCAG 1. 0 Checkpoint • 2. 2 Ensure that foreground and background color combinations provide sufficient contrast when viewed by someone having color deficits… § WCAG 2. 0 Success Criteria • Text (and images of text) have a contrast ratio of at least 5: 1… (from the May 2007 Draft)

What WCAG 2 gives you § Applies to more advanced Web technologies - current, future, non-W 3 C § Adaptable, flexible for different situations, and developing technologies and techniques

WCAG 2. 0 § www. w 3. org/TR/WCAG 20/ § Formal Web standard draft, planned to become a “W 3 C Recommendation” § “Normative”

WCAG 2. 0 Techniques § “Informative” supporting document § Examples for HTML, CSS, etc. § Can be updated

WCAG 2. 0 requirements are more flexible

More design flexibility § WCAG 1. 0 Checkpoint 7. 1: Until user agents allow users to control flickering, avoid causing the screen to flicker § WCAG 2. 0 allows more movement within defined parameters

Scripting allowed!

Scripting Techniques § Providing client-side validation and alert § Using functions of the Document Object Model (DOM) to add content to a page § Using Dynamic Web Content Accessibility to programmatically identify form fields as required §. . .

Flexibility for rich Internet applications § WAI-ARIA: Accessible Rich Internet Applications Suite § Techniques for meeting WCAG 2. 0 § E. g. , accessible and highly usable expanding and collapsing menus/tree controls/nav bars

WAI-ARIA status § Implementations already in browser and screen reader § Documents 1. Technical material for tool and specification developers 2. Best practices for Web content developers
