"Vection field" for pedestrian traffic control

: Today in general traffic field, visual signs and audio cues are used for pedestrian control. As the pedestrians need to acquire and recognize them, time delay between cognition and action occurs. To cope with this problem, some wearable devices were proposed that control the pedestrians intuitively. However, attaching and removing the devices are cumbersome and not practical. In this study, we propose a new visual navigation method for pedestrians using “Vection Field”, where the optical flow is presented on the floor. The optical flow is presented by using lenticular lenses. The lenticular lens, that is the passive optical element, generates the visual stimulus based on the pedestrian’s movement without electrical power supply. In this paper, we designed a basic visual stimulus and evaluated principle of our proposed method for the directional navigation. The results revealed that the optical-flow composed of stripes and random-dot pattern both displace pedestrian’s pathway ...
