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

近年来，关于老年人电动轮椅的热潮已经蔓延开来。因此，电动轮椅随车行驶的事故增多，成为社会问题。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医疗导航系统，以预防此类事故的发生。在跑步实验中，测量了电动轮椅在道路侧向和路面行驶时的头部反应以及对驾驶者的生理和心理影响。这是因为安全确认和情况评估误认为是焦虑造成的事故，如开车等。跑步实验以8名大学生和2名老年人为对象，测量了在…顶区跑步时的加速度变化实验结束后，对受试者的心理影响进行了问卷调查，结果发现，驾车者在倾斜部分向道路、石材路面、巷道在道路下沉、修路等处行驶时，会受到1G以上的加速度。据了解，在这样有缺陷的道路上跑步时，很多受试者都会测量到心室率的上升，感觉不舒服的人很多。此外，当在狭窄的道路上与汽车相遇并在人垃圾中行驶时，心室率有增加的趋势。因为驾驶人的姿态较低，所以即使与行人擦肩而过，紧张程度也会增加。由于这些结果在老年人中变得更加显著，因此有必要根据驾驶者的紧张程度和心率变化来进行行驶速度和自动停车的驾驶支持控制。较少

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.
