Abstract
The purpose of this paper is to discuss and highlight how Cultural-Historical Activity Theory (CHAT) can contribute to the understanding of the different factors at play when a person is using augmentative and alternative communication (AAC). It is based on data from a 3-year project concerning activity-based vocabulary design of voice output communication aids (VOCAs). Four persons who used AAC and their assistants were interviewed about shopping activities and their views about a vocabulary that included pre-stored phrases. A CHAT model, the Activity Diamond, was applied in an analysis of the data. The result was a multiplicity of human, artifactual, and natural factors, in which six themes were identified: Attitude/Preference, Expectation/Trust, Goal/Power, Place/Space, Time/Learning, and Usability/Accessibility. The themes are exemplified and discussed in relation to AAC.
