Experimentally research for the tele-support system for visually impaired by holding common image

本研究的目的是利用高速网络和图像传输关系技术开发视障人士的助行系统，并通过实验验证其有效性。视觉辅助系统听觉地图与远程辅助系统实验在实验中，受试者携带两个设备。其中一个是IC记录器，用于收听听觉地图中录制的指令，另一个是视频蜂窝电话，由远程支持人员导航。12名受试者参加了实验。当受试者迷失方向并意识到仅凭听觉地图无法继续前行时，他们应该使用远程支持者提供的导航服务。实验结果显示，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到达目的地，另有3人未能在规定时间内到达目的地。在这个实验中，我们设计了一条复杂的路线，有很多狭窄的路径，很难找到交叉口。在这项研究中，我们验证了我们的助行系统能够有效地帮助视障人士自己行走。在视障人士避障系统中使用空气刺激作为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侵犯视障人士行走路径的障碍物的方向。我们提出的系统类似于一副眼镜，首先检测到障碍物，然后通过前额的触觉刺激向佩戴者指示其方向。在实验中，我们发现障碍物的方向是通过前额空气刺激感知到的，并且我们的方法可以在实际环境中成功地进行避障。我们相信，这项研究为开发一种实用的避障设备完成了一个成功的阶段，该设备使用空气刺激来指示危险，并改善视障人士的日常生活。少

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.
