摘要

It is extremely difficult for visually impaired people to move around in new places. Because traditional pedestrian navigation systems such as Google Map are designed using visual information such as map displays, they are difficult for visually impaired people to use. The purpose of this research is to develop a wearable system to assist a visually impaired people in navigation. We propose a positioning method combining Radio Frequency Identifier (RFID) and Quasi-Zenith Satellite System (QZSS) to obtain highly accurate positioning both outdoors and indoors. Furthermore, to guide visually impaired persons, it is necessary to sense and guide the direction in which the user is facing, and to detect and avoid obstacles. Therefore, we adopted HoloLens, which can generate a 3D mapping of the environment to estimate the user's direction and to generate a route to avoid obstacles. The system directions are based on the shortest route from the current position to the destination, while dynamically generating a route that avoids obstacles if they are detected. In this paper, the navigation system construction and approaches are described, and then the results of the demonstration experiments are reported. According to the results, positioning accuracy based on RFID and QZSS was achieved with an error of less than 1m. Furthermore, we also confirmed that it is possible to generate an obstacle avoidance route using sequential spatial mapping using HoloLens.
