3. About Me
Brian Kelly
• Early adopter of Web technologies (Jan 1993)
• UK Web Focus at UKOLN: a national post,
advising UK universities on best practices for use
of the Web from 1996-2013
• Now Innovation Advocate at Cetis, encouraging
take-up of innovation technologies and practices
by UK universities

4. Involvement with Web Accessibility
Long-standing involvement with Web accessibility:
• Attended W3C WAI launch, Santa Clara, April 1997
• Many peer-reviewed papers published since 2004,
co-authored with accessibility researchers &
practitioners from UK and Australia
• Awards:
“Implementing A Holistic Approach To E-Learning
Accessibility”: Best research paper at ALT-C 2005
“Developing countries; developing experiences:
approaches to accessibility for the Real World”:
John M Slatin Award for best communications
paper at W4A 2010
• Co-organiser of Accessibility Summit in 2004 and
Accessibility Summit II in 2006

5. WAI Recap
W3C WAI (Web Accessibility Initiative):
• Developed framework for providing “universal
accessibility”
• Has had global impact
• Based on 3 components for:
Content (WCAG)
Authoring (ATAG)
Browsers/User Agents (UAAG)
WCAG 1.0:
• Specific to HTML; had flaws
WCAG 2.0
• Format independent
• POUR principle: requires accessible content to be
Perceivable; Operable; Understandable and Robust
5
6. Realisation of the Limitations
From 1997 - 2002:
• Encouraged universities to use
WCAG guidelines to provide
“universal accessibility”
From 2002-2004:
• Realisation of the limitations,
especially in e-learning context:
“How do I make this
3D molecule in Java accessible?”
“If I provide Alt-text to the images in the
quiz I’m giving the answer away”
6
Conclusions: It’s wrong to think that universal accessibility can
be achieved by simply conforming to a checklist. However
WCAG guidelines do have value, but we need a better solution.
7. “Blended Accessibility for Blended Learning”
7
In 2004 we realised:
• Differences between informational and
learning web services1
• Importance of accessibility of learning
objectives / learning experience rather
than the learning resource2
• Importance of other IT and non-IT
learning environments beyond the Web
Note 1
• We want immediate & simple access
to information
• Understanding & learning is different.
The “understanding” arises through
pedagogical processes discussions,
misunderstandings, “light bulb”, ….
Note 2
Example: a field trip involves trip up a
mountain. This is not accessible. Do we:
• Install wheelchair ramp up mountain?
• Cancel trip as it’s not universally
accessible?
• Seek to make the various experiences
accessible (e.g. team working)?
8. Beyond Accessibility for Learning
Different accessibility challenges for
• Information • Learning • Culture
• Communications • Games • …
8
We identified the importance of context and the
intended purpose of the service for accessibility
9. Relevance of Second Life
Is Second Life Accessible?
Blog post published in Jan 2008:
This video clip shows a user with
cerebral palsy, Judith, using
Second Life with a headwand.
As Judith explains:
‘I’ve got a wheelchair in Second
Life also. You can choose
whether you want to be in a
chair or not. You can have
crutches, you can have whatever
disability you have in real life in
Second Life’
9
Not universally accessible, but
accessible (and valuable) to a
user with disabilities.
This example illustrates need to
have a user-focussed approach to
accessibility standards
10. Revisiting Limitations of WAI
In June 2008 UK
government announced
that all government web
sites must conform to
WCAG AA
Implications:
• What if WCAG is
flawed?
• What about the
costs?
• What about the loss
of services of use to
some/many?
10
There is a need for a standard, but it must be
realistic and address a wide range of use cases.
A new approach much avoid:
• Unnecessary barriers to innovation
• Temptations to delete services which are
accessible to many but not all (cf Judith & SL)
11. People, Policies
and Processes
In 2007 we argued:
• We need a new approach
to accessibility
• We called this approach
“accessibility 2.0”
• Move on focus from digital
resource to:
People (the users and
other stakeholders)
The policies covering
use of web services
The processes which
would ensure that
policies were being
implemented

13. A Standard – BS 8878
In parallel BS 8878 was
developed:
• A British Standard
Code of Practice
• A framework that
allows definition of
the process
undertaken by
organisations to
build or procure an
optimally accessible
web site

People Policies
Processes

15. Conclusions
“Web accessibility is not an intrinsic characteristic of a
digital resource but is determined by complex political,
social and other contextual factors, as well as technical
aspects which are the focus of WAI standardisation
activities. It can therefore be inappropriate to develop
legislation or focus on metrics only associated with
properties of the resource”

A Challenge to Web Accessibility Metrics and Guidelines: Putting People and
Processes First, Cooper et al, W4A 2012
A question for the audience:
Could BS 8878 approach be used in a Second Life
context?

Notas do Editor
Hello, my name is Brian Kelly.
The title of my talk is Web Accessibility is Not (Primarily) About Conformance with Web Accessibility Standards.
Please note that the slides are also available on my UK Web Focus blog. Also feel free to get in touch with me about this presentation.
In my talk I will introduce myself and summarise my early involvement with Web accessibility.
I will summary WAI’s approaches to Web accessibility and describe the limitations of this approach.
I will describe work myself and colleagues were involved in in providing more appropriate approaches for addressing accessibility challenges in a learning context.
I will then describe how these approaches were applied to other context.
I will describe how our approach, which we called “Accessibility 2.0” focusses on people, policies and processes, rather than the web resource.
I will conclude by described how the BS 8878, developed in parallel to our work, provides an appropriate framework for developing or building accessible web sites.
