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 서비스를 제안한다. CAMUS는 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 TV프로그램 추천 및 제어 서비스를 실행할 수 있도록 한다.
