The purpose of this research are developing the travel aid system to support the visually impaired by utilizing a high-speed network and an image transmission relation technologies, and verifying the effectiveness experimentally.1.Experiment of the travel aid system for visually impaired with auditory map and a tele-support systemIn the experiment, the subjects carried two devices. One was an IC recorder to listen to the recorded instruction in the auditory map and another was a video cellular phone to be navigated by a remote supporter. Twelve subjects participated in the experiment. The subjects supposed to use the navigation service provided by a remote supporter when they lose their ways or direction and recognized that they were not able to continue to travel with only the auditory map. As the result of the experiment, one of the twelve subjects reached the destination with only the auditory map, and eight did by using the both of the auditory map and the navigation service, while … More three were not able to get to the destination within the given time. In this experiment, we designed the complicated route with many narrow paths where it was hard to find intersections.In this study, we verified that our travel aid system was effective to assist the visually impaired to walk by themselves.2.Study on the use of Air Stimulation as the Indicator in an Obstacle Avoidance System for the Visually ImpairedIn this study, we propose a device that indicates the direction of an obstacle that is encroaching into the path of a visually impaired person who is walking. Our proposed system which would resemble a pair of eyeglasses, first detects an obstacle and then indicates its direction to the wearer through tactile stimulation to the forehead.In the experiment, we found that obstacle direction was perceived through forehead air stimulation and that obstacle avoidance could be successfully carried out in a practical setting with the assistance of our methods.We believe that this research completes a successful stage towards the development of a practical obstacle avoidance device that uses air stimulation to indicate hazards and improve the everyday lives of the visually impaired.

本研究的目的是利用高速网络和图像传输相关技术开发视障人士助行系统，并通过实验验证其有效性。1.视障人士助行系统的实验研究。一种是IC记录器，用于收听听觉地图中记录的指令，另一种是视频蜂窝电话，供远程支持者导航。12名受试者参加了实验。当受试者迷失了方向或迷路，并意识到他们无法仅凭听觉地图继续旅行时，他们本应使用远程支持者提供的导航服务。作为实验的结果，12名受试者中有1人仅使用听觉地图到达目的地，8人同时使用听觉地图和导航服务，而…还有三个人未能在给定的时间内到达目的地。在本实验中，我们设计了一条复杂的路线，其中有许多狭窄的小路，很难找到交叉点。在本研究中，我们验证了我们的旅行辅助系统对于帮助视障人士自主行走是有效的。2.利用空气刺激作为视障人士避障系统中的指示器的研究在本研究中，我们提出了一种装置，该装置可以指示正在行走的视障人士的路径中的障碍物的方向。我们提出的系统就像一副眼镜，首先探测到障碍物，然后通过触觉刺激前额向佩戴者指示方向。在实验中，我们发现，通过前额空气刺激可以感知障碍物的方向，并且可以在实际环境中借助我们的方法成功地进行避障。我们相信，这项研究完成了开发实用避障装置的成功阶段，该装置利用空气刺激来指示危险，改善视障人士的日常生活。较少
