A Survey on AAC Fringe Vocabulary to Support Personal Assistance Service

Abstract

Objectives: There are increasing demands for personal assistance services which help the disabled to carry out their daily life. To use augmentative and alternative communication (AAC) approaches more effectively in daily communication, it is essential to include the appropriate core and fringe vocabulary in the AAC system. Considering the fact that there are few studies in Korea which have reported fringe vocabulary compared to core vocabulary, this study is aimed to develop a noun list that can be used to promote interactive communication between the disabled and their assistants in each communication situation.Methods: A literature review was conducted to elicit frequently used nouns in each communication situation. Then, a survey was carried out to identify nouns with high word commonality across 105 personal assistants.Results: Sixty-three nouns with more than 50% of word commonality across personal assistants were identified from the 244 fringe vocabulary; consisting of 112 nouns in the area of going out, 29 in cleaning, 27 in personal hygiene, 26 in cooking, 20 in meal supporting, 20 in other service areas, and 10 in commuting.Conclusion: The identified nouns are expected to help people with complex communication needs to express their needs and wants more clearly and effectively using those nouns embedded in their AAC systems. The list of nouns can be used not only for people who receive personal assistance services, but also for people who rely on AAC systems to express their daily needs.
