摘要：People with speech and language disabilities
typically use picture-based communication tools to accomplish
their daily duties. Traditionally, augmentative and alternative
communication (AAC) methods (e.g., gestures and
communication boards) have been utilized for communication.
Traditional systems, however, are inconvenient for impaired
users, because it is difficult to find specific items from a huge
symbol dictionary. Thus, most systems only allow users to
produce a few words or phrases. Users cannot express a large
variety of statements to achieve a desired goal. However, with
these systems, vocabularies can conveniently be seeded from
large database by context-aware mechanisms. Additionally,
most context-aware AAC systems use location as a context. In
this paper, we present a context-aware AAC system that uses
not only location context, but also context history, with a
dynamic user interface. We include vocabulary as a factor of the
context history by leveraging time, week, and frequency to
prioritize AAC categories and items. Moreover, we attach a
variety of complete sentences to each AAC item to assist
impaired users during their daily interactions.
