Abstract

In this paper we propose wear-UCAM, which is a toolkit for context-aware application model in wearable computing. As the rapid developments of mobile technologies and relevant technologies, the interests in wearable computer also become indispensible in both academic and industrial fields. However, there are few research activities on the application framework or toolkit for wearable computing. Hence, we suggest wear-UCAM as the development toolkit for wearable computing applications, where we focus on how to collect relevant user context, manage it, and provide services based on the recognized context. The proposed wear-UCAM includes the abstraction of context processing as well as independence among sensors and services with other components. For the sake of rapid prototyping of the proposed toolkit, we utilize PDA with wireless LAN as a wearable computer. The detail explanation of the implementation and its discussion are presented in this paper.

본 논문에서는 착용형 컴퓨팅을 위한 정형화된 컨텍스트 인식 응용 모형인 wear-UCAM (Unified Context-aware Application Model for Wearable Computing)을 제안한다. 유비쿼터스 컴퓨팅에 대한 관심이 고조되고 이와 함께 관련된 기술들이 발전함에 따라서, 언제 어디서나 손쉽게 컴퓨팅 자원을 활용할 수 있는 사용자 중심의 착용형 컴퓨팅에 관한 연구도 학계나 산업계에서도 활발히 진행 중이다. 제안된 wear-UCAM은 유비쿼터스 컴퓨팅 환경에서 사용자와 관련된 개인 정보를 센서로부터 획득하고 획득된 정보를 처리 및 분석해서 사용자의 컨텍스트에따른 개인화된 서비스를 제공할 수 있는 모델이다. 제안된 wear-UCAM의 특징은 다음과 같다. 1) 센서에서 획득된 정보로부터 사용자 정보 (User Profile)의 갱신, 2) 사용자의 생체 신호 수집 및 생체 신호 분석, 그리고 3) 다른 착용형 컴퓨터나 환경으로부터 사용자에 대한 개인 정보 보호이다. 본 논문에서 제안된 wear-UCAM은 컨텍스트 처리 과정의 추상화 및 센서와 응용 서비스간의 독립성 보장을 위한 다양한 컴포넌트들을 포함하고 있다. 따라서, 제안된 wear-UCAM은 유비쿼터스 컴퓨팅 환경에서 착용형 컴퓨팅에 필요한 사용자 중심의 컨텍스트기반 어플리케이션을 지원할 수 있는 모델이다. 본 논문에서는 제안된 wear-UCAM의 설계와 디자인된 wear-UCAM의 구체적인 구현 방법에 대해서 자세히 설명한다.
