Americans with Disabilities Act - Aiding the
Physically Challenged Worker
ASSISTIVE TECHNOLOGY FOR
COMPUTERS AND PERSONS WITH disABILITIES
Passage of the Rehabilitation Act of 1973
Section 508, the Technology-Related Assistance for
Individuals with disabilities Act of 1988 and The Americans
with Disabilities Act passed in July 1990, all have provided
legislative directives to ensure that handicapped individuals
have "equal access" to electronic equipment.
Specifically, ADA language states that employers will need to
provide "reasonable accommodations" to individuals
with disabilities including steps such as job restructuring
and modification of equipment.
Title I of the Americans with Disability Act
deals with Employment.
- Prohibits discrimination against persons
with disABILITIES in private and public employment
sectors
- Employers can ask only about ability to
perform job
- Employers must make reasonable
accommodations to know physical or mental limitations of
qualified persons unless employer would suffer undue
hardship
- Effective for all employers with 25 or more
employees; 07/26/94 employers with 15 or more employees must
comply.
KEY DEFINITIONS:
Qualified Individual is defined as an individual with a
disABILITY who
- satisfies the requisite skill, experience,
education and other job-related requirements of the
employment position which the individual holds or desires,
and who,
- with or without reasonable accommodation can perform the
essential functions of such a position.
Essential Functions is defined as
- the fundamental job duties of the employment
position the individual with a disability holds or desires
(e.g., the reason the position exists is to perform that
specific function).
Reasonable Accommodation is defined as
- modifications or adjustments to a job
application process that enable a qualified applicant with a
disability to be considered for a position, or
- modifications or adjustments to the work environment, or
to the manner or circumstances under which the position is
customarily performed, that enable a qualified individual
with a disability to perform the essential functions of the
position, or
- modifications or adjustments that enable employees with
a disability to enjoy equal benefits and privileges of
employment as those enjoyed by other similarly situated
employees without disABILITIES.
Undue Hardship is defined as significant difficulty or
expense incurred when considered in light of such factors as
- the nature and cost, overall resources,
size, type of operation, function and location.
- the impact upon the operation.
- the impact upon the ability of other employees to
perform their duties.
Direct Threat is defined as:
- a significant risk of substantial harm to
the health or safety of the individual or others that cannot
be eliminated or reduced by reasonable accommodation. Such
considerations must rely on objective, factual evidence (not
on subjective perception, irrational fears, patronizing
attitudes or stereotypes) about the nature or effect of a
particular disability or disABILITIES in general.
Over the last several years, advances in microcomputer
technology and computer programming have given rise to a new
generation of methods for providing computer access. This new
generation of assistive technologies provides full and
unencumbered access to virtually the complete range of
commercially available microcomputer software. Business can
easily accommodate the special access needs of disabled
computer users without modifying instructional software or
business applications programs. Successful use of assistive
technologies in the business environment depends greatly on a
"team effort". "Team" means the employee,
the supervisor, in-house technical support and other employee
support personnel. This "team effort" is also
critical when selecting the most appropriate equipment for
immediate and future needs. Additionally, accurately defining
"essential job functions" provides the basis for
selection of appropriate assistive technologies. Written job
descriptions must be thoroughly examined and compared with
daily job responsibilities and duties. Personal
Considerations --
In order to make computers accessible to persons who are
disabled, assistive technologies must provide SUITABLE
alternatives for viewing text, entering text and numbers,
reading documents and figures, and navigating menus and
system prompts. Additionally, the following personal
considerations must be addressed:
- Is the disabled individual a competent touch
typist? "Hunt and peck" typing is not a viable
alternative for disabled computer users. Teaching typing in
addition to the application program used is not a productive
use of employee time.
- Has the disabled individual had any previous experience
using computers and assistive technologies? Past computer
experience plays a significant role in how a disabled
individual will perform on the job if a computer is required.
Ideally, the disabled individual will have been sufficiently
trained in basic computer usage and some kind of assistive
technology software/hardware prior to entering the job
market.
- What kind of training is required for the position and
how will it be accomplished with a disabled person?
Appropriate training methods for a person with a disability
will play a significant role in how they will perform in the
work environment.
ASSISTIVE TECHNOLOGY FOR THE VISUALLY IMPAIRED
In order to make computers accessible to persons who are
blind, assistive technology must provide nonvisual
alternatives for these tasks.
- The screen display can be made available in
an auditory mode using screen-reading software and speech
synthesizers,
- in a tactile mode using a refreshable Braille display
which echoes the screen display, or,
- by using a combination of both methods.
- Braille printed output allows the blind computer user
additional access to materials and gives the ability to have
easily accessed notes.
- The use of a Scanner and Optical Character Recognition
(OCR) Software allows the blind computer user access to
almost all printed material. Scanned material could be read
then saved to disk for later retrieval.
- Computerized Note Takers allow the blind individual
unlimited freedom to take notes during staff/departmental
meetings or for any other reason.
ASSISTIVE TECHNOLOGIES FOR PERSONS WITH LOW
VISION
The problem is easily defined: the normal computer screen
is far too small to be read easily by individuals with
limited vision. The solution is to enlarge the text onscreen.
- Software based Large Print programs allow
the low-vision computer user unlimited access to all software
applications either text or graphics based. This solution
provides the greatest amount of flexibility because the
low-vision individual can carry his or her access technology
to any compatible workstation within the business.
- Hardware/Software base Large Print programs perform the
same function as their software counterparts but require the
system to be assigned to one workstation at a time. This
solution is less flexible however, this type of setup will
often times work in mainframe emulation programs when the
software based large print programs will not.
- The use of a Scanner and Optical Character Recognition
Software allows the low-vision computer user access to almost
all printed material. Scanned material could be read onscreen
then saved to disk for later retrieval. Additionally, forms
can be scanned, placed on the screen, filled out then sent to
the printer for distribution.
ASSISTIVE TECHNOLOGIES FOR PERSONS WITH ORTHOPEDIC
disABILITIES
Orthopedic disABILITIES resulting from accidents,
strokes, birth defects and neurological disorders have range
of mobility impairments that are enormously varied.
Additionally, persons with Carpal Tunnel Syndrome present
unique problems employers today. For persons with these types
of disABILITIES, keyboard access and accommodation is
critical.
- Correct Keyboard Positioning will aid in
reducing fatigue and minimize physical exertion associated
with data input.
- Keyboard Access is critical. Multiple keystroke commands
common to many computer applications can be an obstacle to
persons with virtually any degree of orthopedic disability.
- Use of Keyboard Control programs to eliminate automatic
key repeat, multiple key commands through "latching
down" keys and key timing or delay capabilities.
- Enhancing typing speed for persons with mild to moderate
orthopedic disABILITIES whose typing speed is less than 10
words per minute can be accomplished with Word Completion
Programs.
- Speech recognition systems serve as a supplement or even
replacement for data entry on a physical keyboard.
- Low tech solutions for persons with Carpal Tunnel
Syndrome keyboard positioning, keyboard wrist and arm rests,
monitor placement and ergonomic seating are all critical
issues.
ASSISTIVE TECHNOLOGIES FOR PERSONS WHO ARE DEAF OR
HEARING IMPAIRED:
Many computer programs make use of various tones or beeps
to alert the user to error conditions, work completion or
other events. It is essential that deaf or hearing impaired
persons have access to these cues.
- The use of a highly visible prompt with the
ability to change the duration, color, and location of such
prompts.
- Deaf individuals who have problems with written English
benefit from grammar, speller and usage checkers.
