EVEN "ACCESSIBLE" WEBSITES REMAIN DIFFICULT FOR PEOPLE WITH
DISABILITIES, SAYS STUDY

A new study has confirmed what accessibility experts continue to
point out: the Worldwide Web remains pretty un-usable for anyone who
cannot see a conventional computer screen and use a mouse with
dexterity.

"Web usability is three to six times better for non-disabled people
than for people with low vision, no vision or motor impairment," says
Jakob Nielsen, who the New York Times calls "the guru of web page
usability." His firm, the Nielsen Normal group, recently released a
study that shows this pretty conclusively.

Their 104 subjects included users with low vision, no vision, or
motor impairment and a control group of people without disabilities,
who were assigned 4 tasks: Find the average temperature in Dallas in
January; buy Janet Jackson's CD "All for You" from Target's website;
find a bus departing O'Hare airport to a specific address in Chicago
using the Chicago Transit Authority website, and find the best mutual
fund satisfying certain criteria on Schwab's website. The control
group of people without disabilities were able to complete the 4
tasks 78% of the time; screen reader users only 12.5% of the time.
While the control group spent only a little over 7 minutes "on task,"
the others took over twice as long. The control group's error rate
was only .06; screen reader users' error rate was 2.0; screen
magnifier users', 4.5.

"Beyond ALT Text: Making the Web Easy to Use for Users with
Disabilities" was released last week at the Nielsen Norman Group's
Usability conference in Washington, DC. An overview of the 148-page
report is online at

there's a link there for downloading the report ($190). "Bad design
kills Websites," runs the headline of Washington Post internet
columnist Leslie Walker's Oct. 25 story about Nielsen's conference
(online at
http://www.washingtonpost.com/wp-dyn/washtech/techthursday/columns/dotcom
/A4
8167-2001Oct24.html).

Walker's column refers to economics; but Chapman University's Art
Blaser says discussions based only on economic reasons to provide
access miss the point. "When we pass legislation ensuring rights, we
make a statement: those rights are too important to be guaranteed
only when they're cost-effective." Chapman says most "distance
learning" courses today remain inaccessible as well, despite software
that provides access if used correctly. Read Blaser's article online
