Abstract
This paper introduces semiotics to the field of augmentative and alternative communication (AAC). Semiotics includes the study of all types of communicative acts (signs) from language and other complex forms of human communication to animal communication and natural events in our environment. Its object of study overlaps that of AAC: communication. This paper presents semiotics as a methodological and/or theoretical framework that can be useful for AAC researchers and/or professionals to validate AAC terminology, identify sign characteristics, operationalize sign variables, expand sign taxonomies, and understand sign transmission processes (e.g., production and interpretation).
