Abstract

Recently, as the supply of smart phone is spreading and the exhibition industries are rapidly growing, future exhibitions are evolving toward active, customized, interactive, tangible services, which can give more satisfaction to visitors. To realize this services, the indoor localization in the exhibition of visitors is very important and according to the accuracy of localization the quality of services for exhibition are also different. In this paper, state-of-the art indoor localization techniques are investigated and new localization method are proposed. To achieve this goal, future exhibition service types are proposed, which are connected with IT technology. And also, BLE(Bluetooth Low Energy) technology including comparison of specifications and representative localization technologies are analysed. Furthermore we performed comparison study and simulation between RF and VLC channels. Finally based on this, we proposed converged VLC and RF(Wi-Fi and BLE) localization technique for exhibition.

최근 스마트폰 보급이 확산되고 전시 및 관람 산업 시장이 급성장함에 따라 미래 전시관은 관람객에게 보다 큰 만족과 공감을 줄 수 있는 능동적, 실감형, 맞춤형, 인터랙티브 서비스를 제공하는 방향으로 진화하고 있다. 이를 실현하기 위해서는 실내 전시관내에서 관람객의 위치를 파악하는 일은 매우 중요하며, 측위 정밀도에 따라 제공 가능한 전시 서비스 품질도 달라진다. 본 논문에서는 최근 연구되고 있는 실내 위치 인식 기술을 분석하고 전시관에 적합한 측위 방법을 제안하였다. 이를 위해, 먼저 IT 기술과 접목된 미래 지향적 전시 서비스 형태를 도출하고, 최근 출시된 BLE(Bluetooth Low Energy) 기술 및 사양 비교 분석을 포함한 대표적인 측위 기술에 대해 분석하였다. 또한 RF 및 VLC의 두 가지 측면에서 채널 특성을 비교 분석하고 시뮬레이션을 수행하였다. 이를 토대로 전시관을 위해 VLC 및 RF(Wi-Fi 및 BLE) 측위 기술이 결합된 측위 방안을 제안하였다.
