Abstract

In this paper, we implement the signboard voice guidance service for visually impaired person using virtual beacon. The new location to provide a location-based service can be added easily by using virtual beacons, which are locating by Wi-fi, GPS, and so on, instead of physical beacons, which are locating by physical devices. We provide the voice service for guiding information of the captured signboard for the visually impaired when he arrived at the location registered through the virtual beacon.

본 논문에서는 가상비콘을 이용한 시각 장애인 대상 간판 음성 안내 서비스를 구현한다. 물리적으로 위치를 측정하는 물리적 비콘 방식 대신, Wi-Fi, GPS 등의 여러 수단을 통해 위치를 측정하는 가상비콘을 이용하여 물리적인 설치비용 없이 손쉽게 위치를 추가하고, 해당 위치 기반의 서비스를 제공할 수 있다. 본 논문에서는 이러한 가상비콘으로 등록된 지점에 시각장애인이 도착하였을 때, 사진촬영을 유도하여 촬영된 간판에 대한 다양한 정보를 전달하는 서비스를 제공한다.
