This informative resource delves into Section 508 guidelines and Web Content Accessibility Guidelines (WCAG), exploring cognitive barriers on the web, reading disorders, and practical solutions to improve accessibility for users. Learn about flicker prevention, timed responses, and key WCAG priorities to create inclusive web experiences that cater to diverse user needs.

Working to Section 508: Understanding Web Pages Lori Gillen McKesson Health Solutions
Agenda • Demo: Processing information slowly • Cognitive barriers to the Web • How to conquer these barriers • Section 508 • Web Content Accessibility Guidelines
Cognitive barriers to the Web • Reading disorders: • Inability to relate new ideas to those stored in memory • Inability to distinguish or separate sounds in spoken words • Inability to focus attention on reading material • Slow to process information from reading tasks
Section 508 • Refers to Section 508 of the Rehabilitation Act of 1973 • Requires federal agencies or companies working with federal agencies to provide accessible electronic and information technology to federal employees and to the public that these agencies service
Section 508 • Consists of 16 individual standards that must be met for improved accessibility • Most standards pertain to accessibility for people with low-vision • Two standards pertain to people with cognitive disabilities • Flicker • Timed responses
Section 508 • Flicker • Avoid causing the screen to flicker. It can cause seizures in people with photosensitive epilepsy • People with an attention disorder are too distracted to concentrate when they see flicker • If you must have flicker, it should not be greater than 2 cycles per second
Section 508 • Timed responses: • When a timed response is required, alert the user and give a sufficient amount of time • Some people may need more time to read a page than is given in the timed response • Some accessibility experts suggest that you allot 15 minutes for a timed response
Web Content Accessibility Guidelines (WCAG) • First recommended by the World Wide Consortium (W3C) in 1999 • Section 508 was drawn from these guidelines • Within guidelines are checkpoints for determining accessible technology • Checkpoints are categorized by priority to facilitate implementation into existing web sites
Web Content Accessibility Guidelines (WCAG) • Priority 1 indicates that a web site MUST satisfy a specific checkpoint • Priority 2 indicates that a web site SHOULD satisfy a specific checkpoint • Priority 3 indicates that a web site MAY satisfy a specific checkpoint
Web Content Accessibility Guidelines (WCAG) • These WCAG guidelines pertain to people with cognitive disabilities: • Provide context and orientation information • Provide clear navigation mechanisms • Ensure that documents are clear and simple
Web Content Accessibility Guidelines (WCAG) • Provide context and orientation information • Why should you follow this guideline? • To help users who cannot relate new ideas to those stored in memory • What should you do? • Group related elements together using labels, headers, names for frames
Web Content Accessibility Guidelines (WCAG) • Provide clear navigation mechanisms • Why should you follow this guideline? • To keep users who are easily distracted or who process information slowly from getting lost in the web site • What should you do? • Provide a way to return Home • Provide breadcrumbs • Provide a site map • Use navigational icons, ex. front and back arrows
Web Content Accessibility Guidelines (WCAG) • Ensure that documents are clear and simple • Why should you follow this guideline? • To help people who have trouble processing information quickly • To facilitate usage for people whose native language may not be used on your site • What should you do? • Use clear and concise language • Present information in small manageable chunks
