초록

최근의 휴대폰은 단순한 음성통신 기기에서 벗어나 개인용 복합 업무기기 및 생활의 필수기기로 발전하고 있다. 이미 휴대폰을 이용하여 사진이나 동영상은 물론 문서를 생성하고 가공하는 단계로 발전하였으며 센서 기술의 발전에 따라 휴대폰을 통해서 수집된 정보를 분석하여 사용자가 처한 상황에 적절한 서비스를 제공하기 위한 기술이 필요해지 고 있다. 본 논문에서는 모바일 환경에서 발생하는 제약을 극복하여 휴대폰 사용자의 상황을 수집하고 분석하기 위한 확률 기반의 통합형 지능 기술을 제시하고 이를 통해서 가능한 상황인지 서비스를 소개한다. 휴대폰으로 얻을 수 있는 로그로부터 파악된 사용자와 환경의 상황으로 일상을 요약(만화 다이어리)하거나 특정 상황을 검색(라이프 브라우저) 하기도 하고 유관정보를 추천(지능형 폰북)하는 서비스에 대해서 실제 구현과 성능 평가를 통하여 상황인지 기술의 가 능성을 모색한다.

Abstract

Recently, cell phone is not merely a means of voice communication but a necessity of life for providing personal services and business support. Cell phone is already used to write and edit documents as well as create photographs and video data. Context-aware technologies are required to provide user adaptive services with personal information collected in a cell phone with sensors. This paper proposes an integrative intelligent framework based on probability to collect and analyze user's context information by overcoming mobile constraints, and also introduces some possible context-aware services from the framework. Daily life summarization (cartoon diary), context search (life browser), and recommendation (intelligent phone book) services are developed and evaluated to show the feasibility of context-aware services in cell phone.
