Accessibility - what is it and how does it affect your site?
I’m sure that many of you have heard the term before and have a rough
idea of what it means to have an accessible web site but to clarify;
What is Accessibility?
Accessibility is the practice of providing equal access to web sites and web
content for people with disabilities.
Why should I bother it sounds like a lot of work for such a small market?
The number of people with visual disabilities in the UK alone is estimated
to be approximately 1.1 million with the figure for Europe to be around 7.4
million this equates to around 1.9 % of the total European population (source
http://www.euroblind.org).
Apart from the moral and legal reasons for developing an accessible web site,
your site can gain an advantage over your competitors by reaching this market.
In particular Tesco have already seen the benefit of providing an accessible
web site for this community.
So what does the law say about Accessibility?
UK Disability Discrimination Act 1995
Section 21 of the Act gives disabled people improved rights of access to goods,
facilities and services. Department of Education and Employment advice says:
"As a service provider, you might discriminate against a disabled person
in two ways:
By treating him or her less favourably than other customers because of their
disability; or
By not making reasonable adjustments to the way you deliver your services, so
that disabled people can use them."
In October of 2004 this Act comes to full fruition, this means that those companies
without at least a plan to implement changes to meet the guidelines for accessibility
will have no defence against any legal action brought.
Is it likely that Companies will be prosecuted?
The simple answer to this is Yes.
In April 2004, Bert Massie the Chairman of the Disability Rights Commission
reported that
“Organisations that offer goods and services on the Web already have
a legal duty to make their sites accessible. It is clear from the investigation
that these duties are not being fulfilled. The Commission’s policy is
to seek improvement in the first instance through advice and conciliation, and
this report contains a range of recommendations to help website owners and developers
tackle the barriers to inclusive design. However, where the response is inadequate,
we shall be vigorous in the use of our enforcement powers; these range from
“named-party” Formal Investigations which can lead to sanctions
against the owners of inaccessible websites, to the provision of support for
test cases being brought by individual disabled people.”
Who or What are the W3C
The World Wide Web Consortium (W3C) is the organisation which develops standards
for the internet. It is comprised of many of the pioneering developers of the
internet together with people from governments and technology companies the
world over.
The Web Accessibility Initiative (WAI) is a working party set up by W3C to
set standards for making web pages accessible to as many people as possible.
The first major output from this group was a set of guidelines which are seen
as a standard all over the world.
The most sensible option is to act now to ensure that you meet the guideline
set out by the World Wide Web Consortium (W3C), thus avoiding prosecution under the Disability
Discrimination Act.
• Images & animations. Use the alt attribute to describe the function
of each visual
• Image maps. Use client-side MAP and text for hotspots.
• Multimedia. Provide captioning and transcripts of audio, and descriptions
of video
• Hypertext links. Use text that makes sense when read out of context.
For example, avoid "click here."
• Page organization. Use headings, lists, and consistent structure. Use
CSS for layout and style where possible.
• Graphs & charts. Summarize or use the longdesc attribute.
• Scripts, applets, & plug-ins. Provide alternative content in case
active features are inaccessible or unsupported.
• Frames. Use NOFRAMES and meaningful titles.
• Tables. Make line by line reading sensible. Summarize.
• Check your work. Validate. Use the tools, checklist, and guidelines
at www.w3.org/TR/WCAG.
These are the main guidelines but for a more detailed list go to www.w3.org/WAI
Will I need to completely re-design my site?
No, your site only has to appear different to users who wish to view your site
in an alternative manner.
Are there degrees of Accessibility?
Yes, the WAI offers three levels of accreditation:
• A - The site incorporates all the "must-have" checkpoints
of the WAI guidelines. This would achieve basic accessibility to a large proportion of users with disabilities.
This should be your first target in achieving accessibility.
• AA - the site incorporates all the "should-have" checkpoints.
This eliminates all of the major hurdles to users with disabilities
• AAA - the site incorporates all the "may-have" checkpoints.
This eliminates every hurdle to users with disabilities, however, to achieve this you would need a lot of investment and planning and this may not be cost effective for a profit making organisation
Is it only the WAI that has set standards?
No, the Royal National Institute of the Blind (RNIB) offers its own accreditation
- the See It Right mark, which once won, would include your site on a list of
approved companies on the seeitright website page

In addition to this, although not setting standards the Watchfire site “Bobby”
is very helpful in establishing how accessible your site is and helping you to
identify the areas that need to be improved.

Indicium encourages all our clients to ensure that their sites are designed
with accessibility in mind not only for the legal, moral and competitive reasons
but also as a slight aid to the optimisation of the site. Accessible web sites
are very Search Engine friendly; however this is a minor point in comparison
to the reasons already explained.
