THE COGNITIVE AND LEARNING DISABILITIES ACCESSIBILITY TASK FORCE (COGA)
The Cognitive and Learning Disabilities Accessibility Task Force is a task force of the Protocols and Formats Working Group (PFWG) and the Web Content Accessibility Guidelines Working Group.
Aim: To improve Web accessibility for people with cognitive and learning disabilities.

COGA - The work ahead of us, where we are
Some issues
What might we end up with?
COGNITIVE DISABILITIES
Conditions that impact a person’s ability to use a website include:
memory
reading text
problem solving
keeping focused (attention span)
computation (for example calculations)
COGNITIVE DISABILITIES
The largest group of disabilities are people with cognitive disabilities For example: 115 million people with dementia worldwide by 2050
Meanwhile, many systems have become more and more complex Web applications TV interfaces, heating Phone systems
THE COGNITIVE AND LEARNING DISABILITIES ACCESSIBILITY TASK FORCE
Creating a roadmap exploring how to make Web content more accessible and usable by different people and groups of people with Cognitive and Learning Disabilities:
Review existing techniques and how they can be improved
When necessary, develop techniques
Develop suggested enhancements to existing W3C specifications
Develop engineering approaches and author strategies for further review

User groups
• Cognitive functions and symptoms
• Challenges in using ICT/ the Web
• Persona with use cases (challenges)
• How they use the web and ICT to include: Email, apps, voice systems, etc
• Otimized content and special pages
• Specific technologies / guidelines
Technology
• Technology overview
• User group challenges
• Potential for Cog A11y
• WCAG issues: • Adoption of
items relevant to cognitive disabilities and accessibility (Cog A11y)
• What is testable• Use cases
covered
Potential for inclusion
• Ideas of how inclusion could be improved
• Metadata for user to find alternative versions
• Tools for fast creation of alternative content (simplification tools?)
• Adaptive content • Information
resources such as: turning papers into presentations, translations tools
• Disadvantages and risks (e.g.: lowering reading age can be less precise, makes mistakes, etc.)

SOME SIMPLE TECHNIQUES ARE GOOD FOR EVERYONE
Include short tooltips on all icons, jargon
For non-standard UI, a help link should be viewable
Help should be contact sensitive (F1 default?)
Pressing 0 on a phone menu always gets you a person
These are just ideas….nothing formal

2.2.5 When an authenticated session expires, the user can continue the activity without loss of data after re-authenticating. (Level AAA)
Guideline 2.4 Provide ways to help users navigate, find content, and determine where they are. Making links visually distinct (Advisory Techniques for Guideline
2.4)
ISSUE 1 - AUTHOR FREEDOM
•Not necessarily be a legal requirement •for most content
•Many people want to increase their market •or simply accommodate as many people as possible
ISSUE 2
People with different cognitive disabilities often need different things
But • Not always• We can handle it
