Abstract

This study generally is purposed to implementation and usability evaluation of augmentative and alternative communication system (hereinafter referred to as an “AAC system”). Also the device is aimed as an AAC system using symbols for HCI, allowing a handicapped person to make a general communication with others in a free and convenient manner. This study specifically presents a method of predicting predictions, which contributes to reducing the size of the AAC system. This method includes selecting vocabulary and classifying it by domains so as to meet the characteristics of the AAC communication, using a noun thesaurus for semantic analysis, and building a sub-category dictionary. Accordingly, this study has verified the system by applying it to linguistically handicapped persons with different kinds of handicaps two times.
