Abstract
Traditionally, the field of augmentative and alternative communication (AAC) has focused on enhancing the expressive communication of users. However, a number of authors have also described strategies to augment the input provided to AAC users during communication interaction or during instruction in AAC use. The AAC Input Framework (AACIF) described in this paper represents an attempt to clarify the processes of input that occur in AAC by exploring how existing techniques are relevant to AAC users and their partners. Four components—augmenting the message, mapping language and symbols, augmenting retention, and developing a pool of response options—are described. Connections to existing augmented input literature are presented, and clinical examples are provided.
