The
Sound of Surfing
Listening to Web sites through a screen reader such as
Jaws is the best way to appreciate the challenges and issues
that lie behind Web site accessibility. Here's a sampling of
what you'd hear on a visit to the high-traffic Web sites for
the New York Times (http://www.nytimes.com)
and public broadcasting giant WGBH (http://www.wgbh.org).
Hard Times at the Times
The New York Times on the Web immediately gets off on the
wrong foot. The ad graphic in the upper left corner
(A) has no alt text, so Jaws
reads its link aloud--and because sites serve most ads
dynamically from databases, these links are
incomprehensible. In this instance, the Jaws surfing
experience begins as follows: "Page has 131 links. Link
graphic hst one-dash-side-dot-gif slash
six-six-hundred-ninety-six-d-six. . . ." This
numerological gibberish continues for several more seconds.
Simply adding alt="Advertisement" to the image tag would
have eliminated that agony.
Things improve only slightly from here. The site's
designers also fail to specify alt text for the left-hand
image map (B), so Jaws reads
the links thus: "Image map link slash index. Image map link
front slash index. Image map link day slash world. Image map
link day slash national." And on and on.
Finally, the links for each of the main front-page
articles (C) read simply "Go to
article." A blind user surfing from link to link won't know
which article each link designates.
Smooth Talker
The Web site for WGBH in Boston does it right--no surprise,
given that WGBH is headquarters for the National Center for
Accessible Media.
The first thing a Jaws user hears is "Page contains 39
links"--less overwhelming than The New York Times on the
Web's 131 links. From there we hear "Link: D vertical bar.
Link: text version and access instructions. Graphic: This
week." (Thanks to an alt attribute, Jaws doesn't read the
whole file name.) "Link: site map. . . ."
You'll notice that the text links at the very top of the
page (A) enable a blind user to
jump quickly to a text-only version of the site and get
instructions about the site's structure and accessibility
features. The d link (B) leads
to a page containing a description of the home page
graphics--how many there are, what they look like, and so
on--making the site a bit more inclusive.
