Development of LED mounting cane which is easy to recognize to be a cane user for contact accident prevention

随着老年人口的增加，使用拐杖的老年人也在增加。另一方面，夜间使用拐杖的老年人的交通事故正在迅速增加。事故发生的原因在于无法识别使用拐杖的老年人。本研究的目的是开发用于预防接触事故的LED安装手杖。在本研究中，我们以实验方式探讨高能见度LED的理想闪烁条件。我们可以找到LED的闪烁条件，这是很容易认识到是一个手杖用户。并根据拐杖行走者的行走情况，研制了闪烁LED的拐杖。

While elderly people's population increases, the elderly people who use a cane are increasing in number. On the other hand, the traffic accident of the elderly people who use a cane for night is increasing rapidly. The cause of accidents is on the point that the elderly people who use a cane cannot be recognized. The objective of this study is development of the LED mounting cane for contact accident prevention. In this study, we investigate the desirable blink conditions of LED with high visibility experimentally. We could find blink conditions of LED which is easy to recognize to be a cane user. And the cane which blinks LED according to a crutch-walking person's walk aspect was developed.
