This International Standard provides design principles for usable communication support boards that assist in transcending regional/cultural and linguistic barriers and is of substantial benefit for those persons who is to rely on a visual strategy to express their communicative intent.
A communication support board is a tool designed for the use of visual symbols (such as pictorial symbols) to facilitate communication and social interaction when expressive/receptive communication is limited due to physical or linguistic barriers.
Pictorial symbols, as visual expressions internationally, remove communication barriers in daily life when the characteristics of the pictorial symbols are easy to understand and able to be applied regardless of regional/cultural differences.
There are several user groups of pictorial symbols ranging from those who have poor or no communication abilities to those who require enhanced communication support.
It is important that the symbols used for the communication board correspond with the symbols visible in the environment to facilitate communication for the individual using the communication board in society.
