Abstract

A smartphone-based context-aware augmentative and alternative communication (AAC) was applied was in order to enhance the user’s experience by providing simple, adaptive, and intuitive interfaces. Various potential context-aware technologies and AAC usage scenarios were studied, and an efficient communication system was developed by combining smartphone’s multimedia functions and its optimized sensor technologies. The experimental results show that context-awareness accuracy is achieved up to 97%.
