Accessibility is becoming increasingly critical to the Internet
experience. Is your site accessible to people with disabilities?
Is it compatible with browsers other than Internet Explorer?
Continue reading to discover how accessibility can benefit you,
as well as your visitors.
What is accessibility
It is a term that is more associated with architectural thought,
rather than Web Site Design. There is a legislation, which
determines the minimum standards for new buildings. As a result,
new buildings today often have wheelchair ramps, accessible
lifts and disability parking spaces, allowing anyone with
disabilities to gain access to a building, use the provided
services, buy the products, and talk with the people inside.
With web sites, the term traditionally refers to the development
of sites that are accessible to "all" users who may want to
access them -- in other words, "Universal Web Sites." Tim
Berners-Lee, W3C director and inventor of the World Wide Web,
defines it as "access by everyone, regardless of disability."
Even though the World Wide Web is continuously growing, many
users:
* use speech browsers or eyes busy/hands busy, as businessmen
in cars; * don't have the latest graphical browsers and
plug-ins; * surf with slow modems, or reside in rural or remote
areas with limited access to the Internet; * browse without
graphics, using text-only browsers or subscribe to non-graphic
services; * access in noisy, high- or low-light environments;
There are also many users with disabilities as;
* Visual - blind, low vision, color blind; * Auditory - deaf,
hard of hearing; * Motor/physical - paraplegic; *
Cognitive/learning - dyslexic, learning disabled. More at

Accessibility increases benefits for both parties: the User and
the Web site Provider.
Users benefits from accessibility
Every user, regardless of physical, sensory and cognitive
disabilities, constraints and/or technological barriers can:
* access the information; * use the services; * buy the
products; * talk to the people associated with each Web site.
In other words, satisfied users may become loyal users, continue
using the web site, and even recommend to others. Providers
benefits from accessibility
* Increase audience; * Improve maintainability and efficiency;
* Improve and regain reputation; * Satisfy existing and future
legal requirements; * and much more.
Auxiliary benefits of accessible web design
According to the World Accessibility Initiative, providers have
the following benefits:
1. Increase Market Share and Audience Reach Improve usability
for non-disabled and disabled visitors; Support for Low Literacy
Levels; Improve Search Engine listings and Resource Discovery;
Support for the Semantic Web; Re-purpose content for multiple
formats or devices; Increase support for Internationalization;
Assisting access for low-bandwidth users.
2. Improve Efficiency Reduce site maintenance; Site Search
Engine Improvements; Re-purposing Content; Address server-load;
Address server-bandwidth.
3. Demonstrate Social Responsibility
4. Reduce Legal Liability

Accessibility is critical for a web site's success
This narrow focus is at the expense of a much larger segment of
society with milder impairments, such as partial sight, poor
hearing, and poor language skills. The needs of this larger
group can be more easily accommodated with simple and
inexpensive design tips such as resizable text, large tactile
buttons, and clear, easy-to-follow instructions.
We should try to look at things from the point of view of people
who have disabilities. For example, in the UK alone, there are
8.5 million people who are classified as having some sort of
disability. That's a big percentage to exclude from the web;
from a moral viewpoint, it is surely wrong, but from a
commercial viewpoint, it is disastrous.
When designing web pages, try putting them through a text
reader, like the ones used by those with visual impairment. You
will soon realize how difficult it can be for a user who cannot
see that a new window has opened - hence the need to overtly
tell users that a new window has indeed opened.
Apart from the moral and commercial considerations, there is
also the legal. The United Kingdom enforces the Disability
Discrimination, which requires all web sites to show that they
have taken steps to enable access.
With a little bit of thought, accessibility is relatively easy
to implement. It does not require you to do away with
JavaScript, Flash or other Multimedia features, just as long as
you provide an alternative, so your visitors have a choice.
Epilogue
"For people without disabilities, technology makes things
convenient," says Judith Heumann, the U.S. Department of
Education's Assistant Secretary of the Office of Special
Education and Rehabilitative Services, "For people with
disabilities, it makes things possible." Just keep that in
mind.-
