Abstract

Smart phone based navigation applications are very useful in everyday life. Cost-effective and user friendly navigation can be provided to the user by many applications available in market. Using the Smart phone these navigation applications provide accurate navigation for outdoor locations. But providing an accurate navigation underground space such as subway station is still a challenge. It is hence more convenient and appropriate for mobility services if the visitors could simply view the guidance of the subway station on their mobile phone, wherever and whenever it is needed. This study develops a algorithm for indoor navigation with the help of Augmented Reality(AR) and QR marker code from the entrance to the train platform for users. This indoor navigation uses AR and QR maker codes for two purposes: to provide the user link to the subway station location and to provide the current guidance details to the user. This Smart phone algorithm that uses a smart phone optical tool to decode the QR marker to determine the location information and provide guidance to the AR without indoor Maps. This algorithm also provides a module to guide mobility vulnerable to the Barrier Free route to destination.

스마트폰 기반 길안내 애플리케이션은 일상생활에서 매우 유용하다. 또한 비용 효율적이고 사용자 친화적인 내비게이션은 많은 고객을 유치할 수 있다. 하지만 스마트폰을 사용하여 지하철 역사와 같은 지하공간에서 정확한 내비게이션을 제공하는 것은 여전히 어려운 과제이다. 방문객이 지하공간에서 필요할 때마다 언제 어디서나 스마트 폰으로 길 안내를 제공받을 수 있다면 더 편리한 모빌리티 서비스를 제공할 수 있다. 본 연구는 지하철을 이용하는 고객에게 출입구에서 열차 플랫폼까지의 길 안내 시스템을 개발하고 있다. 경로탐색은 새로 제안한 QR 마커와 증강현실(AR)을 적용하여 스마트폰의 광학적 툴로 위치정보를 파악하여 경로안내 정보를 실내 지도 없이 제공하는 비용 효율적인 스마트 폰 알고리즘에 해당한다. 또한 이 알고리즘은 교통약자들에게 별도의 Barrier Free 경로로 안내하는 모듈도 제공하고 있다.
