Abstract
Many people with aphasia experience difficulty recalling words extemporaneously, but can recognize those words when given an image, text, or audio prompt. Augmented and alternative communication (AAC) systems can help address this problem by enabling people with aphasia to browse and select from a list of vocabulary words. However, these systems can be difficult to navigate, especially when they contain large amounts of content. In this paper, we describe the design of TalkAbout, a context-aware, adaptive AAC system that provides users with a word list that is adapted to their current location and conversation partner. We describe the design and development of TalkAbout, which we conducted in collaboration with 5 adults with aphasia. We then present guidelines for developing and evaluating context-aware technology for people with aphasia.
