What is a symbol set?

A symbol set is best understood as a finite or definite collection of symbols that are organized and utilized for a specific purpose, often related to communication in AAC (Augmentative and Alternative Communication) systems. Symbol sets are designed to provide a structured way for users to express ideas, needs, and feelings through a recognizable and coherent method.

In the context of AAC, symbol sets are crucial because they help individuals with communication impairments to convey messages more effectively and efficiently. While options describing endless lists or collections without limits do exist conceptually, symbol sets in practice are curated to meet the needs of users, offering a manageable selection of symbols that are most relevant to their communication requirements. This intentional curation is what differentiates a symbol set from a general or random assortment of images or terms, ensuring a sense of order and usability in communication strategies.
