Abstract

Recently, augmented reality(AR) based building information applications using a smart phone provide information in the static form irrespective of the distance between a user and a target building. If many target buildings are located close to each other, discrimination of information is reduced due to overlapping information objects. Furthermore, it is difficult to intuitively grasp the current position of the user in the previous AR-based applications. In this paper, to solve these limitations, we have designed and implemented a novel building information system in which the location and size of information objects are adaptively displayed according to locations of a user and target buildings, and which allows users to intuitively understand their location by providing a 3D map that displays the user's location and all target buildings within a given distance in real-time. The AR-based building information application proposed in this paper focuses on the building guide in Deoksu Palace in Jung-gu, Seoul.

최근 스마트폰을 이용한 증강현실 기반 건물 안내 어플리케이션들은 사용자의 위치와 목표 건물의 위치 간의 거리에 상관없이 동일한 고정 형태로 정보를 보여주고 있고, 특히 다수의 목표 건물들이 근접하여 위치하고 있을 때 제공 정보들이 중첩하여 디스플레이 됨에 따라 정보 전달력이 떨어지는 제한점이 있다. 또한, 기존 증강현실 기반 어플리케이션에서 사용자의 현재 위치를 직관적으로 파악하는 데는 어려움이 있다. 본 논문에서는 이러한 제한점을 해결하고자 사용자와 건물의 위치에 따라 정보객체의 위치와 크기가 적응적으로 제공되고, 사용자의 위치가 실시간으로 표 시되는 3D 지도를 제 공함으로써 사용자들이 직관적으로 자신의 위치와 건물의 위치를 파악할 수 있도록 하는 안내 시스템을 설계 구현하였다. 본 논문에서 제시한 증강현실 기반 건물 안내 시스템은 서울시 중구에 위치한 덕수궁내의 건물 안내에 초점을 맞추어 제작되었다.
