Abstract

Last few years have seen a rapid increase in research on ubiquitous computing. Ubiquitous computing is often touted as a technology that will make computing available to the user anywhere and anytime. One important problem to be addressed in building such a ubiquitous computing environment is how to manage services and deliver them to the user in an effective manner. This paper presents our model called Personal Kiosk(PK) as a way of solving the problem. PK is a model of ubiquitous service provisioning that enables the user to use desired services anytime and anywhere. The design and implementation of the current PK in the 'Local Area' setting with related technical issues are also presented. A location-sensing technique for indoor users and a personalized service provisioning based on user location and privileges are discussed in detail.

컴퓨팅 서비스가 언제 어디서나 이용 가능한 유비쿼터스 컴퓨팅에 대한 연구가 활발히 진행되고 있다. 유비쿼터스 컴퓨팅 환경을 구축하기 위해 해결해야하는 문제 중 하나는 다양한 특성의 서비스들을 어떻게 효과적으로 제공하고 이를 관리하느냐는 점이다. 기존에 제안된 유비쿼터스 서비스 제공 시스템은 특정 종류의 서비스만을 지원하는데 중점을 두고 있다. 또한 상황과 서비스의 관계 표현 방법이 복잡해 다양한 사용자가 생활하는 복잡한 공간에서 서비스를 제공하는데 어려움이 있다. 본 논문은 이런 문제에 대한 해결 방안으로 Personal Kiosk (PK) 모델을 제안한다. PK는 모바일 단말기를 통해 사용자가 언제 어디서나 유용한 서비스를 사용할 수 있게 해주는 것을 목표로 하는 유비쿼터스 서비스 모델이다. 현재 단계의 PK는 로컬지역을 대상으로 연구되고 있다. 본 논문은 로컬지역에 PK 모델을 구현하기 위해 필요한 실내에서의 정밀한 위치인식기법과 효과적인 서비스 발견기법을 설명하며 이를 바탕으로 사용자의 위치, 권한, 시간정보를 이용해 개인화된 서비스를 제공하는 방법을 설명한다. PK 모델은 서비스를 이용하기 위해 소모되는 사용자의 노력과 시간을 크게 감소시켜 보다 편리한 모바일 서비스 환경을 구축할 수 있게 한다.
