Creating an Accessible Internet
By Mary Barros-Bailey <barrosm@micron.net>, Pauline G. Aguilar <copper11@aol.com>, and Michael R. Burks <mburks952@att.net>
The Internet as a source of information is growing at a rate almost
beyond comprehension. It is without question the greatest and
most accessible collection of resources in history. And though
it is widely accepted that navigating the seemingly endless resources
contained on the Internet is no easy feat for even the most experienced
Internet user, for those with disabilities, the challenges are
especially daunting. While the most formidable task today may
be presenting information in a manner that meets the accessibility
needs of people using screen readers, the overarching issue is
making everything on the Internet usable by the widest audience
possible.
This article discusses the ongoing work of Mary Barros-Bailey,
Michael R. Burks, and Pauline Aguilar. Barros-Bailey is the author
of the book Internet Disabilities Resources, an extensive and exhaustive collection of disability resources
available on the Internet. The first part of this article reflects
the efforts and techniques Barros-Bailey used to write her book.
The second and third parts reflect the efforts of Pauline Aguilar,
who, with the help of Michael Burks, is creating a database of
disabilities resources on the Internet.
Collecting the Resources
By Mary Barros-Bailey
Several years ago, when I was beginning to conduct extensive research
on Internet resources for people with disabilities, I encountered
a man with severe cerebral palsy who had just entered the so-called
cyberworld. His disability rendered him nonverbal and immobile
without assistance. His writing revealed him to be bright and
articulate. He had at some point obtained a journalism degree,
but had not worked in that field or any other field. His passion
was history.
His entrance onto the Internet opened doors and allowed him to
walk through them in ways he never dreamed possible. He could
now walk through any number of museums in the world, tour places
of great historical significance, and communicate with people
from Buffalo to Bangkok. This new world, which many of us without
disabilities take for granted, was to him nothing short of utopia.
Those on the receiving end of his electronic communications judge
him by the merit of his writinghis strengthand not by the way
he looks and what he cannot do. On the Internet, people do not
steal uncomfortable glances at him, treat him like a child, or
ignore him because they are unable to deal with his disability.
He is on equal footing with everyone else.
Or is he? The opportunities the Internet provides for people with
disabilities are truly amazing. And yet, accessibility issues
persist. Because of his spasticity and functional limitations,
my friend had considerable difficulty typing. A simple e-mail
message could take 10 minutes or longer to compose. From his very
small town in northern Idaho, he not only faced issues within
the new medium, but he also had little knowledge about how to
get around them. I referred him to an assistive-technology center
in Spokane, Washington, where he could get help finding better
equipment to assist him in more comfortably striding through the
halls of the National Archives from his wheelchair.
While I am not a technologist, I care about making the world as
accessible to my mother with mobility impairments, my niece with
learning disabilities, or my client with traumatic brain injuries
as it is for me. Often, when I speak before peers, I finish my
presentation by emphasizing Internet accessibility. My peers deal
with accessibility issues and accommodations or retrofitting daily
because of their work as vocational rehabilitation counselors,
rehabilitation nurses, or life-care planners. Yet, they are somehow
baffled by the notion that accessibility issues are present on
the Internet.
In collecting data on Internet disability resources, one must
be as intuitive as possible. In collecting our data, we considered
some of the most common disability types, such as traumatic brain
injuries and spinal cord injuries. First, within each category,
we considered the kinds of resources on the Internet that existed
for each category. We found sites dealing with the whole ball
of waxmegasites where a wide range of information about the disability
could be foundalong with links to other sites. Then we listed
general information sites that might not have lots of links to
other places on the Net about the disability, but which provide
plenty of in-depth information about a disability type. Of course,
it was important to list advocacy organizations as well as research
and treatment centers. In each category, we distinguished among
sites throughout the world.
Apart from researching specific disabilities, we looked at the
complete lifestyle of a person living with a disability and identified
resources covering a wide range of important issues, such as assistive
technology, employment resources, education, leisure, and recreation.
Finally, we wanted to provide a way for individuals to quickly
find information related to disabilities and came up with sites
on government, research, and statistics resources as well as a
list of more than 700 online publications, newsgroups, and mailing
lists.
It is commonly accepted that there are three types of accessibility
issues: hardware, software, and economics. To that I would add
one more: search accessibility. There exists a level of frustration,
and sometimes resentment, toward the Internet by those who feel
that the information contained within it is overwhelming and often
inaccessible in the form it is presented. In helping people steer
around this particular accessibility issue, my presentations tend
to have a greater focus on HTML field search techniquessuch as
url, domain:, image:, title:, link:, and host:which I have found
to be an effective way for compiling data on the Internet.
In addition, continued education on issues of accessibility uses
for anyone dealing with the Internetfrom the programmer to the
end user, to the legislator, to the family member or caregiver
of the person with a disabilityis vitally important. Without
recognition that there are problems, little will occur to ameliorate
those problems.
On the merits of the Internet, shortly after publication of Internet Disabilities Resources, the publisher received a call from the father of a high school
student suffering from tar syndrome. The family was having difficulty
finding college scholarships for their daughter because of their
income level. They had searched and researched many resources,
but they were unable to find much. Somehow, they heard about the
publication and were able to find within the education chapter
the financial aid sources they sought.
In a small, direct, or indirect way, allowing those who need the
resources to access them quickly, effectively, and effortlessly
should be our goal.
Organizing the Resources
By Pauline Aguilar
The process of organizing disability resources on the Internet
begins with gathering those resources and setting up ways for
people to submit resources to a database. The next step is the
organization of the resources themselves into two parts: virtual
organization and physical origination. Both are integral to collecting
and presenting resources. They affect both the storage of the
resources in the database as well as the retrieval and presentation
of the resources to the user. Since the presentation of the resources
will be controlled by the user and the search engine may be masked,
this part of the process is perhaps the most critical.
Virtual Organization
Great care must be taken so that the techniques used to organize
the resources as well as the organizational structure itself are
not subject to change. For example, as new resources are added
and new types of categories appear, or as new presentation strategies
emerge, consideration must be taken to shift the ways the resources
are organized. Resources must be stored and categorized so they
may be organized in multiple ways and included in multiple categories.
To accomplish this, the resources may be formatted and stored
using XML or eXtensible Markup Language. A special DTD is under
development to address the specifics of storage, retrieval, and
presentation of the disability resources. This DTD will allow
for presentation of the resources not only in a visual manner
but through the use of other media as well. The use of this DTD
allows for future expansion of the organization of the resources
and for flexible expandable retrieval techniques.
Organization of the resources should be tied closely to both the
existing categories of resources as they appear on the Internet
and the needs of the user community that will retrieve the resources.
The resources that we will be dealing with fall into two general
categories:
Internet resource categories. These include such things as newsgroups, mailing lists, Web-based
bulletin boards, Web pages and Web sites, chat groups, electronic
news sources, and electronic and hard-copy newsletters. Those
resources serve not only as focal points for users to gather information
but also as signposts for the changes occurring in the disabilities
community. These are the source categories for the content and
provide the basic content of the site.
Content categories. The content categories provide the means by which the site is
organized. The categories are supplied at the time of storage
in the database by means of special tagging procedures provided
in the XML DTD. This is designed such that it will be flexible
and changeable. It is critical to the operation of the system.
It must be able to change with the changes on the Internet and
adapt to new types of content and presentation.
Physical Organization
There are several issues involved with physical organization of
the system. Actual physical organization of the data is done by
means of a database manager and the user of special keyword tags
implemented in the XML DTD. The tags allow the data to be stored,
searched, and retrieved.
Storage issues
Each document that is stored will be one of two types: either
a pointer document that contains a link to the resource or a summary
document that describes an offline resource that is available
to the disabilities community but has no other Internet presence
besides the entry in the database. The keywords that are placed
in the documents will be placed at storage time and will help
make search, retrieval, and presentation of the resources both
accessible and easy. The system will allow modification and addition
of the keywords as needs arise.
Search and Retrieval Issues
One of the most difficult issues on the Internet today concerns
effective searching strategies and techniques. How do you search
such that the results are truly relevant, and how do you ensure
that you are not overwhelmed by the sheer volume of the results
returned? The keyword storage technique is designed to facilitate
quick and accurate searching of the stored resources. In addition,
a dynamic thesaurus can track all variations of keywords.
Another important consideration lies in helping the user create
a search, or create a search that does not appear to be a search.
Bear in mind that many of those who will use the system will have
accessibility issues. The search itself must be accessible, or
the system will lose its utility to the one of the most important
segments of the audience we are trying to reach. This issue will
be dealt with by means of both accessible-forms-based searching
and searching by way of drill-down questioning. While the second
method is not as flexible as the first, it does offer those who
have trouble with forms an easier method of conduction of a search.
Since all results will be dynamically produced from stored data,
the resources that are presented to the user will be from the
latest information available at all times.
Presentation Issues
Storage and retrieval of the data are closely linked to presentation
of the information to the user. An organizational schema that
is flexible enough to change and stable enough to allow the user
to conduct an effective search will provide the basis for accessible
presentation of the information. If users do not have relevant
information related to what they are looking for, the presentation
will make little or no difference. So this can be considered to
be the solid base upon which accessible presentation of the information
will rest.
Presenting the Resources
By Michael R. Burks
Universal design principles (UDPs) declare that the presentation
of information should be accessible to as many people as possible.
Since it is intended that information be presented in an international
arena, those principals can be defined as including non-English
speakers.
As part of the functionality of the database of disabilities resources
on the Internet we are developing, users will be given the option
of choosing the way they wish information to be presented. In
effect the user will choose the view of the data, including format
and visual or nonvisual forms of presentation. Eventually, users
will choose from a set of delivery options, such as fax, hard
copy, Web pages, or e-mail format tailored to specific devices
such as screen readers or devices producing Braille output. The
system will be further designed to interoperate with devices not
yet developed. Within Web pages, the system will deliver specific
formats selected by the user. For example, the Web format will
allow users to decide if they want graphics or if they want the
screen formatted for auditory output and how they want the output
on the screen to appear. The initial version of the system will
focus on producing Web-based output. This output will be usable
by a wide range of Web browsers, but as the implementation proceeds,
other delivery channels will be developed.
Many of the issues we are dealing with are general presentation
issues, such as text size and placement, practical ways for users
to get the presentation they desire, and how to present searches
so as not to confuse and confound users. One of the challenges
will be to present information dynamically but in a timely manner.
The system must be able to produce output for existing channels,
and it must be able to evolve with the appearance of entirely
new information channels. The basic challenges are usability,
flexibility, and scalability. This will be achieved by separating
the content from the presentation. Information will be stored
in the database. The use of XML and other technologies will allow
it to be searched, retrieved, and presented according to user
preferences.
Disability Issues
It is readily apparent that on a site dedicated to collecting,
organizing, and presenting disabilities resources on the Internet,
those resources must be accessible to all. As obvious as this
may seem, a surprising number of sites dedicated to providing
resources for people with disabilities are themselves not accessible
to all. Part of the mission of this system is to present resources
in such a manner.
Language Issues
Just as important as presenting the resources in an accessible
manner is the issue of presenting the resources in the users
language. Initially, the site will be implemented in English.
However, we aim to offer other languages as quickly as possible.
Implementation Issues
Actual presentation of the information to the users will be driven
by a three-tiered process. A users search command will result
in resources being extracted from the database. That information
will be converted into XML for those browsers that support XML
and converted into HTML for those browsers that do not. For those
who can use them, style sheets will be implemented to support
the various types of presentation. There will also be a means
to define the users preferences for browsers that do not support
style sheets. They will then be sent to the users client software
for final processing and presentation to the user.
As soon as possible, the resources will be translated into other
languages. Initially, this will be a manual process. As translation
technology improves, the process will become automated.
User Issues
There are a number of issues that are specific to the way information
will be presented by the users client software.
As much as possible, users will define the way data is presented.
This will allow them to choose the way they wish to have data
presented and the means by which it will be presented, such as
visual, auditory, or tactile. Some of these will have subcategories
that will allow further definition by the user. They will also
allow the system to implement new presentation methods as they
appear.
There are several factors to be considered when processing information
for presentation to the user.
The Users Software
It must be considered that the user may be using something other
than a standard Web browser. The system will be flexible enough
to accommodate as many different types of access as possible,
and it will be set up to add new ones as they appear.
The Format the User Requests
Different formats will require different types of processing.
Even in the limited world of Web browsers there are myriad different
formats that can be used to present information. All of those
must be taken into account from the user preferences and the output
must be built to adhere to what the user has requested. This will
be done using a users preferences as the user has them, and the
format and style will be built dynamically from what the user
has stated as needs.
The Means by Which the User Wishes Data to Be "Displayed"
The term display is deceptive. In this case, it does not refer simply to visual
presentation of information, but presentation of requested information
by any available means. This can include visual, tactile, or auditory.
It can also include a combination of those methods.
The Current Level of Technology
As technology evolves, this system will be designed to implement
new and better methods of presentation as they appear. The system
will be both upgradable and scalable to allow implementation of
new technology in a manner that is as nonintrusive as possible.
This will allow the system to accommodate new methods of presentation
with little disruption to the current user base.
The Future
Developing technology offers great promise in the ways information
can be presented. Such advancements are being leveraged into a
system that will be able to present users with the resources they
have requested and in the manner they have requested them. The
technology will seek to reach as many people as possible in the
ways they prefer or need. Users will be able to view information
the way they prefer rather than the way designers require.
Conclusion
There is great need for a focused collection of Internet resources
related to individuals with disabilities. While collections of
disabilities resources do exist on the Internet, most are not
set up to present output in a manner consistent with the users
needs. There are few if any systems that are designed to adapt
to rapidly changing presentation technology. The system discussed
here seeks to address those issues. One of the purposes of the
system used to present these resources is to give the user the
control of the presentation. This will make information presented
to the user accessible to the widest audience possible.
