Understanding Universal Symbols
Not everybody is fully able. Some
people are born with disabilities, others acquire them due to injury,
and anyone who lives long enough will likely acquire a disability of
some sort. These people want, need, and deserve access to our communities.
 |
Access
for Individuals Who Are Blind or Have Low Vision
This symbol may be used to indicate access for people who are blind
or have low vision, including: a guided tour, a path to a nature
trail or a scent garden in a park; and a tactile tour or a museum
exhibition that may be touched. (For other than Print or Braille) |
 |
Symbol
for Accessibility
The wheelchair symbol should only be used
to indicate access for individuals with limited mobility including
wheelchair users. For example, the symbol is used to indicate an
accessible entrance, bathroom or that a phone is lowered for wheelchair
users. Remember that a ramped entrance is not completely accessible
if there are no curb cuts, and an elevator is not accessible if
it can only be reached via steps. |
 |
Telephone
Typewriter (TTY)
This device is also known as a text telephone
(TT), or telecommunications device for the deaf (TDD). TTY indicates
a device used with the telephone for communication with and between
deaf, hard of hearing, speech impaired and/or hearing persons. |
 |
Volume
Control Telephone
This symbol indicates the location of telephones
that have handsets with amplified sound and/or adjustable volume
controls. |
 |
Assistive
Listening Systems
These systems transmit amplified sound via
hearing aids, headsets or other devices. They include infrared,
loop and FM systems. Portable systems may be available from the
same audiovisual equipment suppliers that service conferences and
meetings. |
 |
Accessible
Print (18 pt. or Larger)
The symbol for large print is "Large
Print" printed in 18 pt. or larger text. In addition to indicating
that large print versions of books, pamphlets, museum guides and
theater programs are available, you may use the symbol on conference
or membership forms to indicate that print materials may be provided
in large print. Sans serif or modified serif print with good contrast
is important, and special attention should be paid to letter and
word spacing. |
 |
Sign
Language Interpretation
The symbol indicates that Sign Language Interpretation
is provided for a lecture, tour, film, performance, conference or
other program. |
 |
The
Information Symbol
The most valuable commodity of today's society
is information; to a person with a disability it is essential. For
example, the symbol may be used on signage or on a floor plan to
indicate the location of the information or security desk, where
there is more specific information or materials concerning access
accommodations and services such as "LARGE PRINT" materials,
audio cassette recordings of materials, or sign interpreted tours. |
 |
Closed
Captioning (CC)
This symbol indicates a choice for whether
or not to display captions for a television program or videotape.
TV sets that have a built-in or a separate decoder are equipped
to display dialogue for programs that are captioned when selected
by the viewer. The Television Decoder Circuitry Act of 1990 requires
TV sets (with screens 13" or larger) to have built-in decoders
as of July, 1993. Also, videos that are part of exhibitions may
be closed captioned using the symbol with instruction to press a
button for captioning. |
 |
Opened
Captioning (OC)
This symbol indicates that captions, which
translate dialogue and other sounds in print, are always displayed
on the videotape, movie or television program. Open Captioning is
preferred by many including deaf and hard-of-hearing individuals,
and people whose second language is English. In addition, it is
helpful in teaching children how to read and in keeping sound levels
to a minimum in museums and restaurants. |
 |
Braille Symboll
This symbol indicates that printed material
is available in Braille, including exhibition labeling, publications
and signage. |
 |
Audio Description
A service for persons who are blind or have
low vision Audio Description makes the performing arts, visual arts,
television, video, and film more accessible. Description of visual
elements is provided by a trained Audio Describer through the Secondary
Audio Program (SAP) of televisions and monitors equipped with stereo
sound. An adapter for non-stereo TVs is available through the American
Foundation for the Blind, (800) 829-0500. For live Audio Description,
a trained Audio Describer offers live commentary or narration (via
headphones and a small transmitter) consisting of concise, objective
descriptions of visual elements: i.e., a theater performance or
a visual arts exhibition. |
 |
Ramps
Ramps are essential for wheelchair users if
elevators or lifts are not available to connect different levels.
However, some people who use walking aids have difficulty with ramps
and prefer stairs. Although ramp slopes between 1:16 and 1:20 are
preferred the rule of thumb for constructing a ramp is 12"
of length for every inch of rise. The ability to manage an incline
is related to both its slope and its length. Wheelchair users with
disabilities affecting their arms or with low stamina have serious
difficulty using inclines. In fact many ambulatory people and most
people who use wheelchairs can manage a slope of even 1:16. |
