What is accessibility?

What is Accessibility?
• Web accessibility refers to the
inclusive practice of removing
barriers that prevent interaction
with, or access to websites, by
people with disabilities. When sites
are correctly designed, developed
and edited, all users have equal
access to information and
functionality.
Why?
No one is the same
Diversity
We’re a mixed bunch of people from around the world, different languages,
different cultures. No one is the same. We are unique and beautiful.
The Case
http://www.w3.org/WAI/bcase/socog-case-study
Sydney Olympics
2000
“I am comfortably satisfied that his [the plaintiff]
limited access to the web site caused him
considerable feelings of hurt, humiliation and
rejection. One cannot overstate the consequential
effect upon him of his having to cope with the
persistent need to counter what he saw as a
negative, unhelpful and dismissive attitude on the
part of an organization charged with the presentation
of the most notable sporting event in the history of
this country.”
It’s the law!

Misconceptions
I want to change your
perspective on
accessibility.
Web accessibility is a
mindset not a checklist

commentary/2012/09/web-
accessibility-is-a-mindset-not-a-
checklist
It’s not hard to do
We should look at
accessibility as a part of the
process, not an after thought
Everything we design
and build can be
accessible.
It’s a matter of
understanding
