Users of augmentative and alternative communication (AAC) aids could benefit from novel methods for accelerating access to contextually relevant vocabulary. This paper describes our initial efforts toward improving access to situational vocabulary through the use of geographic context to predict vocabulary. A corpus of spoken data produced by one…

Research on AAC symbols has focused almost exclusively on iconicity and complexity, and thus has not established whether additional visual features are necessary for conveying meaning in graphic representations. Despite variations in individual depictions of an "apple," we understand the underlying concept due to shared consensus on the set of…

Two prototype voice output communication aids were implemented to compare methods of graphic symbol message formulation; one emulated current devices that require syntactical ordering of icons (Default) and the other used semantic frames (iconCHAT). Message constructions of eight typically developing children (7-10 years of age) using both…

It has been well documented that individuals with significant physical disabilities who use augmentative and alternative communication (AAC) face considerable challenges in finding and maintaining employment. This article documents the experiences of one individual, Anthony Arnold, a young man who uses a Pathfinder[TM] for communication and a…

Case studies are an accepted method for reporting treatment outcomes. However, to be useful and authentic, a systematic and principled approach to collecting, analyzing, and reporting case data must be observed. This paper proposes a basic case study format for documenting augmentative and alternative communication (AAC) intervention to ensure…
