Word Board

A communication tool used in augmentative and alternative communication (AAC) consisting of words, common phrases, and sometimes alphabet letters arranged on a physical board or digital display. Users compose messages by pointing to items on the board. Words are typically grouped using syntactic, semantic, or thematic categorization schemes. Paper-based word boards remain widely used due to their low cost, portability, and reliability, though they require a communication partner to interpret selections. Computer-based word boards add advantages like speech output and independent message construction.
