title: The effect of the communication output method on augmented interaction.
abstract: The experiment compared the ability of a Comprehension Model versus an Interaction Model to account for the communication performance of augmented communicators. Five dyads consisting of adults without disabilities, with one participant in each dyad randomly assigned to use an augmentative communication device, engaged in ten direction-giving tasks in which the augmented communicator used either a Word Method (i.e., spoken words only) or a Mixed Method (i.e., mix of spoken words and letters) speech output. Results indicated an overall completion time and communication rate advantage for the Mixed Method output in most communication tasks, supporting the Interaction Model of augmented communication. The role of communication co-construction in augmented interaction and the implications of the Interaction Model for future communication device design are discussed.
