Abstract

This study compared the efficiency and effectiveness of a variety of augmentative and alternative (AAC) devices for ordering meals in fast food restaurants. The duration of the transaction served as the dependent measure of communicative efficiency. The number of requests for clarification produced by the clerk served as a dependent measure of communicative effectiveness. Results showed that each of the devices studied has the potential to provide the user with an effective means of ordering food at a fast food restaurant. Ways to optimize AAC systems and communicative interactions are also discussed.
