To provide a method for notifying a blind person or a healthy person under a visual blind environment, such as in the dark, that a person is approaching.SOLUTION: A warning device mounted on a device user 2 with a size not impeding walking, indicates danger by performing low frequency energization to a living skin, without depending on a sound or a vibration by which information cannot be detected in some environments. Such a method is also provided that has little stress caused by current intensity setting satisfying the optimum condition for suppressing increase of a heart rate caused by energization.SELECTED DRAWING: Figure 1
【課題】盲人や暗闇など視覚遮断下環境の健常者に、人が接近していることを知らせる方法を提供する。【解決手段】装置利用者2に、歩行を妨げない大きさで装着する警告装置は、環境によっては情報を感知できない場合のある音や振動によらず、低周波通電を生体の皮膚に行うことで危険を知らせる。通電に伴う心拍数の増加を抑える最適条件を満たす電流強度設定によるストレスの少ない方法も備える。【選択図】図1
