Utterance-based systems: organization and design of AAC interfaces

Electronic Augmented and Alternative Communication (AAC) systems provide a method for people with severe speech impairments to communicate by selecting what they desire to say, and have the system "speak" it for them. AAC interfaces present many unique design challenges due to the wide variation of physical ability among AAC users. A goal of technological aids for AAC users is to bridge the communication gap, increasing both rate and comprehensiveness of communication [2]. Here we focus on the design of an utterance-based system developed for literate, high-functioning adults interacting in public goaldirected situations with unfamiliar partners. This research involves the design and development of a coherent and intuitive AAC interface for an utterance-based system built upon theoretical evidence and observation of commercial-grade AAC interface software.
