Making Your Site Accessible - The Tyranny of Images
Providing ALT text for images is one of the simplest,
and most frequently ignored, ways of adding flexibility to a web
site.
For various reasons, a significant number of web users
browse with text-only browsers or with image-loading turned off.
They may be too busy to wait for graphics to load, or just have
a slow connection. They may be visually impaired and be relying
on screen reading software. They may be using a digital phone device
with a small screen - and if all they want is your phone number
so they can place that million-dollar order, it would be a shame
if they couldn't find it.
Whatever the reason, browsing without images can be
an unnecessarily frustrating experience. Many sites are totally
unusable without graphics, particularly where navigation relies
on them.
There is no doubt images on web pages can be interesting
and attractive. They can unify a site, giving it a distinctive look
and feel. But are they more important than the users?
It is so easy to add ALT text to graphics and client-side
image maps. All you have to do is remember that the ALT text replaces
the image.
Unfortunately, when working with graphics, web developers
often become totally engrossed in The Design of a site. They are
lazy, or they forget (or deliberately exclude) users who will not
see the images. It would be a pity if that user with the digital
phone and the million-dollar order is forced to leave a site because
they can't navigate without ALT text.
Making Your Site Accessible - Navigation Blues
Navigating through a complex site can often be confusing
for the user. It is not easy, but providing clear paths to information
is critical.
As a web site grows, it becomes more and more difficult
to provide the user with clear navigation paths. Site maps and search
facilities become important, but basic navigation is still the key
to usability.
The developer often knows his site so well that it
becomes impossible for him to view it objectively. Unfortunately,
deadlines and budgets often mean that usability testing is minimal
or non-existent.
Yet, if the user can't find the information they
need, the entire site becomes useless to them. So, what do you do
if the deadline has passed, the budget has been exceeded, and the
site is up without that all-important usability testing? Personally,
I would hope I get lots of feedback from the users.
Making Your Site Accessible - The Importance of
Feedback
Feedback from users is a critical source of information
for web site developers, and should not be ignored.
We have all experienced the problems faced by web
users - slow sites that rely on graphics, nifty scripts that crash
browsers or just don't work, dead links, confusing navigation, frames
that hang around long after you have tried to leave them behind...
Faced with these situations, most users will leave
without comment. But a precious few will let you know - if you provide
the opportunity.
Unfortunately, some web sites provide no obvious avenue
for complaint (or praise). And those that do often receive complaints
less than gracefully.
User feedback is a web designer's window to the real
world. Since it is impossible to predict the needs of every user:
• Actively solicit feedback from users
• Respond politely, even to rude or angry
users
• Seriously consider the possibility
that the user might have a legitimate cause for complaint which
you can rectify
With good design and a bit of luck, you may even get
some positive responses!
