Symbol-Based Communication

A form of augmentative communication that uses visual symbols — including pictures, photographs, line drawings, or icons — to represent words, concepts, or messages. Symbol-based communication is particularly useful for people with limited literacy, intellectual disabilities, or language barriers, as symbols can transcend written language. AAC devices may offer symbol sets like PCS (Picture Communication Symbols), Widgit, or custom photographs. In the Global South, culturally appropriate symbols that reflect local objects, foods, places, and social practices are essential but often lacking in commercially available symbol sets.
