Abstract

Augmentative and alternative communication(AAC) is a communication tool for those with impairments or restrictions on the production or comprehension of spoken language. Traditional AAC has used a portable board with pictures and texts with which disabled person could be supported by it. Currently, smart phone based AAC researches and developments are actively studying. With emerging concepts of context-aware computing, the mobile devices can provide mobile users with timely information and location based services. We proposed a adjustable AAC system for disabled people of which has variable layouts and selectable items. We also implemented context-ware application for AAC systems including time, location and click count informations on smart phone. The system can adaptively change its layout and select AAC items depending on various situation of disabled persons.

보완대체 의사소통도구는 구어(口語)로 자신의 의사를 표현할 수 없는 장애인의 의사소통을 보조하는 상호작용 시스템으로 전통적으로는 그림이나 글자로 된 의사 소통판을 활용하여 왔다. 최근에는 스마트폰 기기 등의 높은 휴대성을 가진 기기를 이용한 의사소통도구의 연구가 활발하게 이루어지고 있다. 또한 최근 상황인식 컴퓨팅의 개념이 출현하면서 모바일 디바이스는 사용자에서 즉시적이며 위치기반서비스를 제공하는 주요도구가 되고 있다. 본 논문에서는 스마트 기기의 다양한 멀티미디어 기능을 이용한 장애인을 위한 맞춤형 보완대체 의사소통도구 제안한다. 맞춤형 의사소통도구를 위해서 가변적인 레이아웃과 장애정도에 따른 AAC 항목의 선택이 가능하게 하였으며 시간정보, 위치정보, 그리고 클릭 수 등의 상황인식 기능을 적용하였다.
