헬스케어를 위한 상황인식기반 스마트 홈 시스템

Abstract

Smart home services, which are highly qualified and differentiated services, are provided for users by actively recognizing the context regarding users and circumstantial conditions. In this application, context-aware middleware is one of the most crucial technologies required to implement the ubiquitous services. In this paper, I propose a method of presenting ubiquitous services effectively in a user-specific space. Smart home service middleware based on context awareness was designed and implemented, where context information from various sensors is gathered, suitable services being inferred and then provided to users. Also by monitoring vital information from bio-sensors such as EKG, blood pressure, pulse sensors, intelligent health care service middleware based on context awareness was implemented. In our approach, user services can be modeled easily by using facts and rules, and the system can be extended easily to support various ubiquitous services other than intelligent home services. One of those services will monitor the emergency situation and vital information by checking the vital information for health care. The system extension capability was assured by the design of the common interface which supports various devices and the shared framework for providing the intelligent services. The database system can be protected from the data loss due to the system halt by storing the facts, rules and situation information periodically using the data backup supervising module. Additionally, it can be integrated with external applications and legacy systems effectively by utilizing various protocols such as socket and HTTP, XML, JESS and etc. I have designed various facts and rules for intelligent home services in real environments. The system was developed in JESS and applied to monitoring the vital information for the health care. The result shows that smart home services can be provided to users effectively in a home environment.
