초록

실내외 환경에서 실험을 수행할 때에 피험자의 상태를 모니터링 하여 위험한 상황을 미연에 방지하고, 실시간으로 처리해야 하는 데이터를 효과적으로 관리할 수 있는 시스템이 필요하다. 이전 연구에서 우리는 목적지까지 안전하게 보행할 수 있도록 하는 시각장애인용 보행안내 기기를 개발하였다. 이 기기는 실내외 특정 위치마다 POI (Point of Interest)를 설정하고 실내에서는 인공 표식(landmark), 실외에서는 직비(ZigBee) 모듈을 이용하고 보행 경로 탐색 알고리즘을 개발하여 사용자의 보행 위치를 추정할 수 있다. 실제 테스트베드에서는 시각장애인이나 안대를 착용한 일반인을 대상으로 실험을 수행하므로 실험 대상자가 위험 상황에 노출될 수 있고, 기기의 오작동으로 인해 문제가 발생할 수 있기 때문에 실험 대상자를 원격으로 모니터링 하는 것이 필요하고 대용량의 실내외 지도 데이터를 저장하고 관리하는 것이 중요하다. 본 논문에서는 실험 대상자를 원격으로 모니터링 하고 대용량의 지도 데이터를 처리하는 제어 관리용 시스템을 소개한다. 실험을 수행할 때에 위험한 상황을 미연에 방지하고자 피험자의 상태를 모니터링 하고, 대량의 데이터를 효과적으로 관리할 수 있는 관리용 시스템을 제작하였고, 다양한 실험을 통하여 제안하는 시스템의 유효성을 입증하였다.

When performing experiments in indoor and outdoor environment, we need a system that monitors a volunteer to prevent dangerous situations and efficiently manages the data in real time. We developed a guidance device for visually impaired person that guides the user to walk safely to the destination in the previous study. We set a POI (Point of Interest) of a specific location indoors and outdoors and tracks the user's position and navigate the walking path using artificial markers and ZigBee modules as landmark. In addition, we develop path finding algorithm to be used for navigation in the guidance device. In the test bed, the volunteers are exposed to dangerous situations and can be an accident due to malfunction of the device since they are visually impaired person or normal person wearing a eye patch. Therefore the device requires a system that remotely monitors the volunteer wearing guidance device and manages indoor or outdoor a lot of map data. In this paper, we introduce a managing system that monitors the volunteers remotely and handles map data efficiently. We implement a management system which can monitor the volunteer in order to prevent a hazardous situation and effectively manage large amounts of data. In addition, we verified the effectiveness of the proposed system through various experiments.
