Equal Opportunity Web
New tools tackle old problems facing disabled computer users.
(3/26/97) -- Tens of millions of disabled Americans now have access to
cyberspace with the help of an assortment of new tools that use speech
synthesis, keyboard alternatives, and other technologies to address
visual, auditory, and motor impairments. These tools allow computers
to talk, magnify, and translate text into Braille. There's even a new
tool called Microsoft Active Accessibility for Java, which makes Java
more accessible to disabled computer users.
Graphical Nightmare
Though Federal laws, such as the Telecommunications Act and the
Americans with Disabilities Act, mandate that computer systems be
accessible to people with disabilities, few actually are. That's
because the digital revolution of the late eighties to the
mid-nineties has emphasized ease of use, which translates into
less-text-based environments in exchange for better looking graphical
ones.
The move began with the advent of Windows and accelerated with a slew
of graphical applications for accessing the Web's hypertext interface.
Until recently, this trend has been at odds with the needs of the
disabled, 27 million of whom are visually impaired and can't make use
of .gifs and .jpegs or "Shocked" Web pages.
All that is changing. People with visual impairments who want access
to the Internet now have options. Various programs enlarge, magnify,
or alter information on screen so it's more readable. Other tools
print text into Braille using Computer Braille Code (CBC), which
precisely transcribes terms relating to computers.
Talking Browsers for Visual Impairments
Web pages can also be converted into speech. One such program is
Web-On-Call Voice Browser, which allows users with only a phone to
access Internet or intranet sites without a computer or modem.
Disabled users can navigate via a phone's keypad and request Web site
contents in the form of pre-recorded audio clips or request to have
text-to-speech synthesis read to them. Users can even send the
contents of a Web page via fax, e-mail, or postal mail.
Productivity Works' approach to the talking Web browser is a little
different. The pwWebSpeak browser is designed for those who want to
access the Internet but can't use a keyboard or monitor and for those
who are blind or visually impaired. The software translates the
contents of a Web page into speech via a speech synthesizer. Users can
navigate a document based on its contents, such as headlines,
paragraphs, or sentences, rather than scroll down a screen display.
CompuServe is soon planning to integrate a similar Windows-based
screen-reading program into its service. The software, called JAWS for
Windows (JFW), is from Henter Joyce, a company that provides access
for people with disabilities.
Keyboard Alternatives for Motor Impairments
Motor disabilities, which can restrict mouse movements or keyboard
typing, are the most common types of impairments. There are several
programs available that deal with varying levels of motor
disabilities. Some programs enable people to "type" using a pointing
device or their voice. Technologies such as word and phrase prediction
require fewer keystrokes and allow computer users to type more
quickly. Trackballs and touch screens are also viable solutions.
Visual HTMLboard, from Adaptive Computer Systems, combines some of
these technologies to let disabled users create their own Web pages.
Through the help of an on-screen keyboard and any word processor or
text editor, users can create hypertext documents without using the
actual keyboard. Visual HTMLboard uses arrow keys to position and
apply HTML tags.
Guidelines for Web Developers
Paul Fontaine of the Center for Information Technology Accommodation
offers a few basic guidelines for Web site developers who want to
maintain sites that are accessible to the disabled. These include:
* providing associated text for graphic images;
* providing text transcriptions or descriptions for all audio clips;
* providing alternate schemes for online forms;
* limiting the use of proprietary extensions, which can make Braille
translation difficult.
As the Web grows, the World Wide Web Consortium, the international
organization charged with developing common standards for the Web, is
making its position on Web accessibility clear: "All the protocols and
languages we issue as recommendations should meet or exceed
established accessibility goals. In addition, we will actively
encourage the development of Web software and content that is
accessible to people with most disabilities."--Angela Hickman
