Standardisation in AccessibilityPeter Korn, Accessibility Principal & ÆGIS Technical Manager
What is a Standard?• De-facto standards: – Width of a road• Decreed standards: – Imperial measure: inch, foot, yard• Standards from a standards process: – Metric measure: meter, liter, gram
What is a Standards Body?• Entity whose primary activities are developing, coordinating, promulgating, revising, amending, reissuing, interpreting, or otherwise maintaining one or more standards
Role of Standards in ICT Generally• For software interoperability – Networking standards allow different computers, platforms, to communicate• For sharing of information – Document standards allow different applications to read & write the same files• For anything heterogeneous
Role of Standards in ICT Accessibility(Role of Accessibility in ICT Standards)• For accessibility interoperability: – How does AT work with ICT (and vice-versa)? – How do apps follow platform themes?• For needed accessibility information – How to encode text for images in documents? – How to encode tables for AT use?
Importance of Open Standards• Open standards can be read, implemented by anyone, at any time, on any platform• Open standards bodies provide ways for experts to join, contribute – Enables ongoing improvement to standards – Therefore enables accessibility improvements
Developing ICT Accessibility Standards• Ingredients for success – Deep understanding of accessibility needs – Plethora of real-world experience – Active implementation(s) proving proposals• Applies to all accessibility standards – Dedicated accessibility standards – Standards supporting accessibility
Accessibility Standards & ÆGIS• “Definition of Accessibility” commonly done as a standard• ÆGIS will do some combination of: – Define accessibility standards – Implement accessibility standards – Identify gaps in accessibility standards • Contribute improvements addressing those gaps
Successful Accessibility Standards• Dont exist in a vacuum – Tools to help create, validate implementations• Multiple (and interoperable) implementations – May have a “reference implementation” – May have open source implementation(s) • Not necessarily best, but often “definitive”
Valorisation of Accessibility• What is “valorisation”? – Realization of value• In the context of ÆGIS and this session – Realizing the value of accessibility standards – Accessibility solutions realized from research
Remainder of this Parallel Session• Accessibility standards work – Dr. Galinski: accessibility standards in content – Dr. Martinez: assessing accessibility conformance to the ISO 9241-171 standard – Mr. Strobbe: Accessibility standards research – Dr. Bund: pluggable accessible user interfaces
Remainder of this Parallel Session, cont.• Accessibility valorisation – Dr. Usero: open source & cloud accessibility – Mr. Lundälv: language support for authors – Mr. Kalogirou: mobile device accessibility
