This publication was originally released in 1989 and, as such, does not contain
the most current information on assistive technology. NICHCY offers this document
on the Internet with the caveat that, while readers can gain basic information
about assistive technology from this document, it is important that they supplement
this overview with more current readings from other sources. For current resources

Today, a nonverbal child
speaks with the help of an electronic communication aid. A student with learning
disabilities masters math facts using a computer game. A child with vision problems
can benefit from an inexpensive device that enlarges printed words on the computer
screen. And for more severe vision problems, there are speech synthesizers that
can be used with computers to convert typewritten words or text into an electronic
voice. For the child who has a
physical disability, there are special devices that will allow him or her to
input information into the computer without using the conventional keyboard.
This can be done through the use of a single switch or some type of voice recognition
system. There are other alternative input devices that can be used simply by
touching the computer screen or touching points on a touch-sensitive tablet
that correspond to the points on the computer screen. Computer and other technologies
have expanded and enriched lives and given many children with disabilities options
not imagined a decade ago. As there is a wide array of assistive technology,
so too are there many decisions, choices and options for families and professionals.
Making informed decisions about technology is a challenge that many consumers
will encounter in coming years. Resources are available to assist consumers
such as: current periodicals; disability, parent, and professional organizations;
national technology centers; and private companies. Walking the assistive technology
maze can be made less complex and confusing by understanding the implications
of technology in the lives of children and youth with disabilities, and by knowing
where to go for help. THEN AND NOW In the late 1800s, the population
of the U.S. was growing rapidly. Census information, gathered by hand, resulted
in long delays and inaccuracy in the information reported about the nation's
population. In fact, the 1880 census took eight years to count. Estimates at
that time indicated that if the census process continued in the same manner,
the 1890 census would take twelve years to complete and the 1930 census would
be available in 1985. Help arrived in the form
of the 1890 Census Machine developed by John Shaw Billings and Herman Hollerith.
The 1890 census took three years to complete and computerization was underway.
Hollerith turned to big business to market the invention, now called the Tabulating
Machine. He joined a company that eventually called itself International Business
Machines (IBM). IBM joined with Harvard in 1938 to create the first electronic
computer, the Mark I. The Mark I required 46,000 vacuum tubes to perform its
operations. The ENIAC computer, completed
in 1947, weighed 30 tons, stood nine feet tall, and took up 1,500 square feet.
In 1951 the UNIVAC computer was completed. Weighing in at a mere 3 tons and
occupying only 575 square feet, UNIVAC was the first computer to handle numbers
and words. Commercially produced computers continued to evolve, with more power
packed into less space at a lower price. In 1973, the first computer
chip, the 8080, was manufactured by Intel. Less than a square inch in area and
thin as cardboard, this chip can perform a million calculations per second (like
the ENIAC) but only costs about $4 to purchase. These chips are inexpensive
because their main ingredient is silicon, which is more common than sand, and
they are produced in enormous quantities (Budoff, Thormann, and Gras, 1985).
Computers were the beginning
of the new information technology. Information (facts, knowledge, data, and
news) technology (materials, tools, systems and techniques) is the key to economic
growth. It is likely to bring about substantial changes in society and may change
lives -- for better or worse -- in a very short time. It will improve the quality
of life for many people by making information more accessible and providing
more information at a low cost which will increase opportunities for all. The
greatest gain will be to the educationally disadvantaged, among them, students
with disabilities (Hawkridge, Vincent, and Hales, 1985). The interest in using computer
technology with people with disabilities began in October 1981 with the Johns
Hopkins First National Search for Applications of Personal Computing to Aid
the Handicapped. In November 1980, the Applied Physics Laboratory at The Johns
Hopkins University began a national search for applications of personal computing
to aid the handicapped. Enthusiastic responses from professionals, amateurs,
and students resulted in introductory workshops and regional fairs, and culminated
in an exhibit of the top national entries at the National Academy of Sciences,
an awards ceremony in Washington, D.C., and a two-day workshop on computing
for the handicapped at Johns Hopkins in October 1981. In March 1983, The Council
for Exceptional Children held its First National Conference on the Use of Microcomputers
in Education. This conference reflected the need for basic workshops on microcomputer
use and for information on practical applications of computers in special education.
In 1983 CEC/ERIC published: Microcomputers in Special Education by Florence
M. Tabor; The Exceptional Parent magazine published its first annual technology
issue; and the IEEE held its first Computer Society Workshop on Computers in
the Education and Employment of the Handicapped. 1984 saw the first U.S.
Office of Special Education Programs (OSEP) document published by COSMOS Corporation:
Microcomputer Implementation in Schools by Robert K. Yin and J. Lunne White.
The document described and analyzed the use of microcomputers in the schools
and district offices of 12 school districts. In September, 1984, Closing The
Gap held its first conference on Computer Technology for the Handicapped. A
1985 OSEP publication, Robotics, Artificial Intelligence, Computer Simulation:
Future Applications in Special Education, by Gwendolyn B. Moore, Robert K. Yin,
and Elizabeth A. Lahm, identified ways in which technologies might be used to
help special education students in the future. The vehicle for introducing
technological devices for educational use was put into place in 1975 with the
passage of the Education of the Handicapped Act (EHA), P.L.94-142. Increased
federal interest was demonstrated with the passage of the Amendments to the
Education of the Handicapped Act of 1986, P.L. 99-457. These amendments created
a new Part G designed to promote the use of new technology, media, and materials
in the education of students with disabilities. Discretionary grants under this
new authority were targeted to: - assess usage and promote
effectiveness;
- design and adapt new
technology, media, and materials;
- assist public and private
sectors in development and marketing; and
- disseminate information.
More recently, the Technology-Related
Assistance for Individuals with Disabilities Act of 1988, P.L. 100-407, was
signed into law. The primary purpose of the act is to assist states in developing
and implementing statewide programs of technology-related assistance for meeting
the needs of individuals with disabilities. The program will enable individuals
with disabilities to acquire assistive technology devices and services. Over
a three year period, all states will have the opportunity to get federal assistance
for developing and establishing their statewide program. The legislation refers to
technology-related assistance and allows each state to decide what is meant
by technology-related assistance. The term does include, however, two separate
components: services and devices. Assistive devices are not
a new area of interest created by the new law. As shown above, interest in the
new higher technologies began shortly after the silicon chip invention. Prior
to that, low technology assistive devices were being developed and used for
centuries. Consequently, definitions of what an assistive device is are numerous,
and are often based on the perspective of a specific agency or disability group.
The wide variety of assistive
devices, and their applications to children and youth with disabilities, is
currently receiving a great deal of attention from many disability-related fields.
This flurry of activity stems from the potential that new and emerging technologies
hold for individuals with disabilities to lead full and independent lives. The
cases below provide only a few examples of the versatility and application of
technology and their benefits. TECHNOLOGY APPLICATIONS Case 1:
A high school student with a visual impairment in a Current Events class has
an assignment to follow a recent major event, present available facts about
it, write a report, and complete a presentation about the event to his classmates.
A major source of information for his sighted classmates is the newspaper, but
unless someone reads it to him, he cannot use that source. The radio is an available
option, but typically radio news coverage contains too little detail. With the
available computer technologies, though, he can receive the newspaper on a computer
disk and, using his personal computer equipped with synthesized speech, he can
auditorily scan the newspaper, find relevant articles, and have the computer
read them to him. Using the same computer, he can begin to write his paper,
print it out in braille so he can check it and change it if necessary, and then
print it in standard text to hand into his teacher. Case 2:
An adolescent with quadraparalysis shows all the signs of becoming a teenager.
She wants control of her own life: to decide which radio station to listen to,
to decide when to turn the reading light off at night, to call her friends and
have a private conversation, and to stay home alone when her parents go out.
Without assistive devices she would be unable to be an independent teenager,
but with a single switch connected to an environmental control unit and placed
on her head, she can control her personal radio, turn the lights on and off,
access the telephone for calling friends, and call for emergency help when her
parents are out. Case 3:
A toddler with severe disabilities attends a special education preschool program.
The teachers are unable to determine the child's cognitive abilities because
the child has no verbal skills and very few motor skills. In the past, teachers
had few ideas for appropriate educational programs for this type of child. As
a result of available technologies, the child's educational program includes
motor training, language and communication training, and teachers can more easily
see the child's potential and can build on it. Now the teachers are working
on training him to use a consistent motor response using switches and battery-operated
toys. The child is learning to reach and touch a switch which turns on a battery-operated
teddy bear. Other times the child has two or three switches to choose from and
must decide which toy is preferable. The language therapist is using the same
switches to teach the child to make consistent "yes" and "no"
responses for communication. COMPUTERS FOR HOME USE
Many of the computers purchased
each year are bought for use in the home. Well over 50% of home computer owners
report that the major reason for buying a computer is for educational applications.
Exactly how computers are used depends on the software selected. Depending on
the design and content, software can present new skills or concepts, reinforce
previously learned skills, or require the learner to apply skills to a task
or problem. Educational software generally falls into four categories: drill
and practice, tutorial, simulations, and games. Tool software such as word processing
are another option. Each type of software can be used for instruction at home.
Drill and Practice. These
programs provide opportunities for the child to practice previously learned
skills. The content of the drill and practice program is usually structured,
focusing on a specific sequence or kind of skill-building. For many students
with disabilities, drill and practice activities are very important for mastering
skills, and using this kind of software at home can reinforce learning that
takes place at school. Tutorials. These programs
introduce new skills or concepts. It is assumed that the learner has not been
introduced to the material presented in the software. The child may have learned
related skills, but the content of the software is essentially new. Because
the content is new, the learner will need guidance and supervision which aids
understanding and teaches correct use from the beginning. Simulations. Simulations
are a type of problem-solving software. The learner applies skills and information
that they have mastered. Simulations place learners in real life situations.
The learner applies rules, uses facts, and draws conclusions to solve a problem.
In addition to academic skills, simulations require good coordination and keyboarding
ability. The necessary academic and physical skills should be assessed when
considering this type of program for a child with a disability. Games. Computer-based games
can be either drill and practice or problem-solving activities. Arcade-style
games are usually drill and practice programs. The learner practices skills
by competing with the program in which facts or problems are presented. The
learner is timed and gets points for giving the correct answer within the time
limit. Tool Software. This software
helps the user find, organize, and reorganize information. Word processing programs,
database management systems, and music or graphics editors are all examples
of tool software. No content is specified with tool software. Instead, the program
provides a framework for writing, creating files, or drawing. To use a word
processing program or a spreadsheet, the learner must become familiar with its
features. Tool programs are more versatile for home use than drill and practice
or tutorial programs and family members can use them for different purposes.
Many possibilities exist
for computer learning at home. Yet, because of differences in age, skills, and
interests, few products will appeal to all members of the family. Knowing how
your child learns and thinks about his or her strengths or weaknesses is important
for it can affect learning. SELECTING ASSISTIVE TECHNOLOGY
EQUIPMENT: BECOMING INFORMED Technology is an investment.
Therefore, consumers should become more informed and critical of the limitations
of technology. Consumers should also be aware of alternate possibilities for
achieving a specific goal. In addition to standard
considerations such as cost, available software, expandability, ease of use,
and available peripherals, it is also important to consider how adaptable the
hardware is. For students with special needs, adaptability in most types of
materials is necessary. For example, students with physical disabilities might
need to use switches which are operated by a head movement, a head wand, a foot
switch, an eye blink, or a sip and puff method. Students with a visual impairment
may need a speech synthesizer. For students with a moderate disability, a combination
of speech synthesis and alternative inputs may be necessary. For students with
behavioral or attention disabilities, timing is important. In addition, a special
feature that is essential to these students is just how fast the computer can
load programs from the disk. Fortunately, there is a
wealth of information that parents and professionals can access, thus allowing
them to make informed choices about the products they purchase and the services
they select. 1. Where to Begin.
If you are interested in using computers or assistive technology with your child
but do not know where to being, start by reading general information on the
subject. There are books available as well as publications, some of which are
specific to special needs. 2. School and Community
Services.
Print information alone may not be enough to help you with your technology decisions.
You may need to contact agencies and organizations that provide special services.
To do this, first become aware of resources that exist in your community. Local
resources can supply personalized assistance to fit technology to your child.
Perhaps the most important
community resource is the school. Your child's teacher can often help you assess
the potential of using technology at home given your child's needs. The teacher
may also be able to guide you in selecting appropriate software for your child.
Some districts allow parents to borrow computer equipment for home use. Another local resource is
a computer users' group. User groups can provide valuable information about
the use of software and hardware. Technical questions can be answered by members
who are experienced with both. Check with your local computer dealer or telephone
directory to find a user group in your area. Computer manufacturers may also
know of a local user group. 3. Specific Information.
If you are looking for information about using technology with a child with
a specific disability, try contacting the local chapter of the disability organization
serving that population. For example, if your child has a learning disability,
contact the local Learning Disabilities Association of America (LDAA). Other organizations like
the Easter Seal Society and the United Cerebral Palsy Association often provide
direct services to families and to local schools in the use of technology. Given the number and different
types of computers that are available today, it is almost impossible to do a
comparison. Generally, though, one or two factors tend to influence your decision
to purchase particular equipment. These factors might include specific software
compatibility, cost, or compatibility with other computers in the school. Some questions to ask when
considering a computer system are: - Do the software programs
you plan to use run on this computer?
- Is the amount of memory
of the computer sufficient to operate the software you plan to use?
- Can the memory be expanded?
- Is a color monitor necessary?
- Does the software you
plan to use work with the printer?
- Can the printer print
graphics?
- How much will the total
computer system cost (including monitor, printer, disk drives)?
While you may not be able
to afford all the options you want initially, think of the future. You will
want a computer that can be useful in a number of situations and can be adapted
to suit different needs. 4. Hardware.
Hardware information may be harder to find locally. Computer dealers that sell
computer systems can usually be found in most cities. Companies that sell assistive
or adaptive equipment may need to be contacted directly. 5. Software.
Your local public library can be a gold mine for information on computer software.
Some libraries set up mini computer labs for the public use. Another source for software
information is your local computer store. National chains such as B. Dalton
and Egghead carry a good selection of instructional software for all ages. Some
software companies cater to the home market. Scholastic and Broderbund issue
home market catalogs so you can shop by mail. Some parents may be able
to contact special software preview centers, operated by school districts or
universities. Since most of these preview centers cater to teachers, call first
to make sure parents are welcome. 6. Assistive Technology.
If you don't know what assistive equipment is needed, local hospitals and community
rehabilitation or vocational centers may be active in designing and fitting
assistive devices to complement your child's capabilities. Some states have
established centers to provide information about particular devices. 7. Funding.
Finding funding for technology devices requires an individualized approach.
To begin your search, check out resources that are available to you locally,
such as the Lions or Kiwanis Clubs, and religious organizations. Nationally, the Easter Seal
Society in connection with IBM has an assistance project that allows eligible
persons with disabilities to purchase discounted computer systems. Additional
funding sources may soon emerge with new federal legislation and more national
interest in technology by insurance companies. To really make technology
work for you and your child, it is important to become an informed consumer.
Use the abundant resources available; read about technology, talk to others
who use it, and try out various technology options before you buy. REFERENCES Budoff, M., Thormann, J.,
