There are many types of
alternative communication systems. Most people are familiar with the most
common system, sign language. Another method has been developed using
line drawings symbolizing words. Symbols are drawn on
individual cards which are handed to the "listener," or placed on a
stable communication board, and desired words indicated by pointing to a given
symbol. The purpose of an alternative communication system is to empower
a non-verbal individual to make requests and communicate their thoughts and
feelings, thereby becoming more independent and self-sufficient.
A major benefit of these visual systems is their ease of use. A non-verbal
individual can quickly learn to use this method, and the symbols are readily
understood by the person with whom they are trying to communicate. These
symbols can be hand drawn, or constructed using a computer program such as Boardmaker by Mayer-Johnson.
Each system is designed to
address the unique needs of the individual, and to meet the specific demands of
the environment in which he or she lives. The level of complexity of the
system can be increased as the person becomes more efficient in using it,
eventually enabling the him or her to construct complete thoughts and sentences
using symbols. Often, because each line drawing is paired with the
written word, the person will begin reading, even though they cannot speak.
