Abstract
This paper discusses the safety requirements to install dynamic signs around the stairs in the facility, in order to safely install and design dynamic signs in consideration of human cognitive characteristics. This paper discusses safety requirements when installing dynamic signs. The discussion is based on the results of observing behavior and measuring lines of sight of facility users in field tests where signs are installed around the stairs inside an event facility. The results reported in this paper shows that the dynamic signs provided on the floor at the bottom of the stairs exhibited a guiding effect on the facility users as they went down the stairs. Also, when the behavior of facility users going up and down stairs was observed, no congestion or contact accidents were caused due to people reading the content of the dynamic signs on the floor, or being preoccupied by the signs. However, facility users moved while watching the sign by central vision for a short time of approximately 2 s or less, and it was found that there is a possibility of misrecognition if the sign presentation position is not within the visual field during movement.
