What are common accessibility
or/and usability errors found on websites?
Do you care about issues from W3C (w3.org)? |
Eric
Jordan:
This is an interesting question for
me, since many people in the Web industry
would probably tell you that I am the last
person you should pose this question to.
I consider myself a “liberal”
when it comes to accessibility and/or usability,
as I typically opt for giving the designer
and/or information architect the freedom
to decide how much attention should be paid
to usability, if any.
I can, however, tell you that in the course
of running a professional Web Design Studio,
I have come to learn that you cannot simply
ignore these types of issues and run around
designing websites like a cowboy, winging
it as you go. It all depends on the type
of project, the type of client, the target
market, and the collective views of everyone
involved in the project as to how closely
you follow the standards of accessibility
and usability.
Working with my team over the course of
the past year, many issues have been brought
to my attention that do indeed have an impact
on the success of a project, whereas before
I would have tended to dismiss them. I give
a lot of credit to my team for this. Some
issues are more important than others of
course, depending on the particular situation,
therefore it is tough to peg general rules
that apply to every website, but there are
some common standards that everyone should
try to adhere to. Some of the standards
we try to follow are as follows:
First, you should never assume that Flash
should be crammed down the audience’s
throat, unless you really understand the
audience. It is a fact that not everyone
loves Flash. Being a Flash advocate, it
is an issue that I wrestle with time and
time again, but is a fact nonetheless. What
2Advanced started doing about 3 years ago,
is providing people with a “turn flash
off” button. This allows for the user
to load an alternate version of the site
where any flash components have been replaced
with html counterparts. We try to recommend
this to as many clients as we can, although
some are reluctant for various reasons such
as budget constraints, time concerns, etc..
It takes extra resources and money to build
the alternate metaphors. However, we have
received very positive feedback regarding
sites that we have deployed this feature
on.
Another fundamental usability/accessibility
nightmare is the use of frames. It took
us a while to learn this lesson, but I can
say that of all the websites we have developed
in the past 3 years, I cannot recall one
that made use of frames. Frames essentially
breach the model that Web is built on: a
system of pages with a unique URL. Frames
go against this fundamental principle, making
pages no longer an atomic unit of information.
I know what you are thinking: “Well
then doesn’t Flash break that same
principle?” It did, until recently.
Before, the information in Flash movies
could only be accessed from the top layer
of information and navigating down to it.
One of our aims in 2006 at 2Advanced was
to develop a system of deep-linking into
flash movies that could be directly accessed
from a unique web URL. We implemented this
system in the latest version of our website,
“Attractor”.
We have been recommending it to our clients
ever since (to those who have the budget
for it of course).
Another error that many websites typically
make when it comes to usability, is allowing
the important content to get lost in the
presentation. A large part of our ongoing
adoption of (reasonable) standards is simply
the separation of the content layer from
the presentation layer. As a Flash-heavy
studio, we search for every opportunity
to improve the delivery of important information
and not allow it to get lost in the wiz-bang
of Flash. For this reason, we almost always
push some sort of hybrid design, a marriage
of Flash and HTML that best serves the user,
by enhancing their experience from a design/aesthetic
perspective and still allowing them easy
and intuitive access to important information.
This also improves SEO rankings, thus achieving
the best of all worlds; a slick design,
easy access to information, and great rankings
with search engines.

Nielsen:
The biggest accessibility problem is
definitely low-literacy users, because they
constitute 40% of the population. Most current
websites are much too complicated for this
big group of people who can't understand
the information that's being presented.
Sadly, nobody cares about low literacy.
I have one consulting client that does,
but otherwise there has been zero interest
in our research on usability
for low-literacy users.
The second biggest problem is older users,
who are about 15% of the population. They
have a lot of special issues related to
the human aging process, including reduced
eyesight, precision of movement, and memory.
Again, almost nobody cares about this large
(and rich, I might add) group of users.
The usability
guidelines to support older users is
one of our least-selling reports. It's fascinating
to conduct user research with seniors, so
I don't regret doing these projects, but
it's sad that so few companies care about
the findings. Many websites could increase
their sales substantially if only they would
start catering to older users.
The W3C issues are certainly important as
well, but they are not the most important
ones because they focus on the technology
instead of human needs. Yes, the technology
should work, and I am grateful that somebody
takes care of that. We definitely need standards
so that when a user goes to a website, the
headline will display if using a visual
browser or be read aloud if using an auditory
browser. But what should that headline say?
Can people comprehend it? Do they understand
where they are and what the product does
that you are trying to sell them? Those
are usability questions that should be resolved
though user research, not technology standards.
Lynda
Weinman:
The biggest culprits: text size that
can’t be altered, lack of alt tags
and text labels, using graphics for text
instead of markup, exclusive use of multimédia,
lack of contrast in color. Usability issues
include unclear navigation, bad search or
no search, and no contact information. I
care about the issues personally—yes.
I think everyone will be forced to care
eventually. Right now Target is being sued
because their site isn’t accessible.
If that case wins, my suspicion is that
major corporate websites and smaller sites
alike will scramble to become compliant.

Mullenweg:
The biggest problems I have with most
websites is bad typography, overly small
type, and lack of clear navigation. I care
deeply about the W3C, and I'm a member of
the Web Standards Project. Sometimes the
organization can be fairly opaque and academic,
but I would never even consider a developer
who isn't familiar with the specs where
they absolutely nail it, like CSS 2.1 and
XHTML 1.0.
Nick
Finck:
On an accessibility level it's often
things like pages that are only accessible
via JavaScript or information that is not
captioned or otherwise accessible in a Flash
file. Those are the more common ones but
others such as tab order come up once you
start looking at common accessibility issues
in web applications. On a usability level
there are hundreds. Everything from mystery
meat navigation (thank
you Vincent) to links that don't look
like links to any degree.
So when you say do I care about issues from
the W3C.... when it could potentially cost
a company like Target
millions of dollars an impact the very core
of how e-commerce sites are coded, you sure
as heck bet I care. That aside, I care on
a professional level because I care about
the quality of code and markup I am delivering..
it's what separates the hobbyists from the
craftsmen.
Todd
Purgason:
Well being that most our work is advertising
based and very visual/interactive we don’t
really pay much attention to accessibility
issues.
Sodaplay:
To my continued embarrassment the old
Sodaplay dates back to some of the least
accessible graphic design dogmas of the
web in 2000 with tiny un-scalable text and
an irrational aversion to upper case letters.
These days we’re much more mindful
about creating designs that work on all
levels and so accessibility is an integral
aspect of our process. W3C is a useful tool
but no more. [ top ]
WeWorkForThem:
There are many reasons I use the sites
that I do, information being the number
one reason. Many sites do not treat information
as something that should be organized and
thought through. When we used to design
sites, we often spent a day or more just
on narrowing down sections, placing info
into other areas, working on how the user
will access the info, etc etc. The “KISS
(keep it simple stupid)” is great,
but you really need someone who can do that
job and sometimes simple isn’t “thoughtful”.
Another job of design is to present the
organized information in a clean and functional
manner. This is also another problem. You
have these web standards people who know
very little about design, yet they are experts
in the subject because it is a new format?
I hate to be the bearer of bad news, but
many people solved many of these issues
in the mid 1900’s and the rules apply
to the web. Read grid systems, think about
it for two seconds and you can easily see
how it transforms over to the web. I often
thought about writing a grid systems for
the web, but I couldn’t be so arrogant.
So I may be missing out on a lot of things
but I have this frustration with usability
experts. It’s sometimes painful to
use the net because of poor decisions with
big sites. Even the back end (how the code
is written) is a huge problem also. A slow
or broken website is pretty much an unusable
site.
