Development of remote type healthcare navigation system for accident reduction of the electric wheelchair

近年来，关于老年人用电动轮椅的研究逐渐兴起。因此，电动轮椅随车事故也随之增加，这已成为一个社会问题。本研究旨在开发将ITS技术与生物医学测量的健康监测相结合的远程健康监护导航系统，以预防此类事故的发生。在行驶实验中，测量了电动轮椅在道路侧面和人行道上行驶时的头部反应以及驾驶人的生理和心理影响。这是因为有很多人由于安全确认和情况评估被误认为是由于与汽车相互通过等焦虑而造成的事故。跑步实验以8名大学生和2名老年人为被试，测量了绕顶骨跑步时的加速度变化 ...更多信息 结果表明，驾驶者在路面倾斜、石子路面、路面塌陷、维修路面等情况下行驶时，受到的加速度在1G以上，已经理解，当在这种有缺陷的道路上跑步时，在许多受试者中测量到心室率的上升，并且有许多人感到不愉快。此外，心室率往往会增加时，通过对方与汽车在狭窄的道路和运行在人的垃圾。因为驾驶人的方面是低的，已经理解的是，即使它是通过彼此与行人的紧张局势增加。由于这些结果对于老年人变得更加显著，因此有必要参考驾驶员的紧张程度和心跳变化来进行行驶速度和自动停止的驾驶支持控制。少

It has spread about the electric wheelchair for the senior citizen in recent years. Therefore, the electric wheelchair's accident with the vehicle increases, and this is become social problem. In this research, it aims at the development of the remote health care navigation system that integrate the ITS technology with the health monitoring of the biomedical measurement to prevent such an accident beforehand.In the running experiment, the measurement of the head response when running in the road sideward and the pavement with the electric wheelchair and driving person's physiological and psychological influence were examined. This is because there are a lot of people who cause the accident since the safety confirmation and the situation assessment are mistaken from the anxiety by passing each other with the car etc. The running experiment did eight university students and two senior citizens as the subjects, measured the change of the acceleration when running about the parietal region … More and the waist and the ventricular rate, and after the experiment, did the questionnaire survey of subject's psychological influence.As a result, it turned out that those who drove received the acceleration of 1G or more when the inclination part to a road, the stone pavement and the roadway running about the road sinking and the repair road, etc. It has been understood that the rise of the ventricular rate is measured in a lot of subjects when running about such a defective road, and there are a lot of people who feel the unpleasantness. Moreover, the ventricular rate tends to increase when the time of passing each other with the car in a narrow road and running in the person garbage. Because driving person's aspect is low, it has been understood that the tension increases even if it is passing each other with the pedestrian. Since these results became more remarkable for the senior citizen, it is necessary to do the driving support control of the running speed and automatic stopped referring to the driving person's tension level and heart beat change.
