Disability Design
- Visual, Auditory, Physical, Speech, Cognitive
- Important Design Principles:
- Separate presentation from structure and semantics
- Establish a clear & consistent navigation pattern
- Ensure interoperability between mainstream applications and

Benefits of Web Accessibility Standard Harmonization
- Create a unified market demand / drive development
- Better authoring tools and more interoperable AT
- Reuse of training and education materials/technical assistance
- Guarantee of vendor independence (both software/hardware)
- Guarantee of universality (across language, culture)
- Guarantee of durability
How do we address fragmentation ?
- Increase participation from regional groups in guidelines
development
- Increase officialness of W3C standards
- Adding a new process for Authorized translations
- Foster local support/outreach vs. duplication of technical
work
- Explain the responsibility: continued evolution means continued
obligation
- Focusing on the importance of Harmonization
