スマートフォンを用いた視覚障害者の転落リスク警告システムの駅ホームにおける実証実験

抄録

In this paper, the effectiveness of a fall risk alert system using a smartphone with a LiDAR sensor is verified based on the behavior of the system in a demonstration experiment at an actual station platform. As a result, we have confirmed that the estimated risk increased when entering the edge of the platform, indicating that this system works in a real environment and can alert fall risk. It was also shown that the alert timing occurs near the tactile paving, which means that the system can provide alerts equivalent to the tactile paving. In the future, we plan to verify the effectiveness of this system in more detail by conducting experiments involving more participants and situations other than the scenarios in this experiment.
