Abstract

With the advent of ubiquitous computing environments, it has become increasingly important for applications to take full advantage of context information, such as the user's location, to offer greater services to the user without any explicit request. In this paper, we propose context-aware active services on the basis of CAMUS (Context-Aware Middleware for URC Systems). CAMUS is a middleware for providing context-aware applications with development and execution methodology. Accordingly, the applications developed by CAMUS respond in a timely fashion to contexts. To evaluate, we apply proposed active services to TV application domain. Therefore, we implement and experiment the TV contents recommendation service agent, control service agent and TV task based on CAMUS. The context-aware TV task is to recommend programs and control of TV according to user preference, location and voice commands.

유비쿼터스 컴퓨팅 환경이 도래함에 따라 사용자의 명시적 요구에 따라 제공되는 서비스 보다는 상황정보를 활용하여 능동적인 서비스를 지원할 수 있는 기술이 필요하다. 따라서 본 논문에서는 컨텐츠 추천 서비스 에이전트와 상황인식 기반 태스크를 포함하는 CAMUS(Context-Aware Middleware for URC Systems) 시스템을 이용한 상황인식 기반 능동형 서버스를 제안한다. CAMUS 는 사용자의 요청이 없더라도 로봇 또는 컴퓨터가 현재의 상황을 인식하여 그 상황에 맞는 정보와 서비스를 제공할 수 있도록 지원하는 소프트웨어 프레임워크이다. 제안된 서비스를 평가하기 위하여 TV 응용 도메인에 적용한다. 이를 위해, TV 프로그램 추천 및 TV 제어 서비스 에이전트 그리고 TV 도우미 태스크를 구현한다. TV 도우미 태스크는 사용자 위치, 음성 등의 상황 정보에 따라 TV 프로그램 추천 및 제어 서비스를 실행할 수 있도록 한다.
