Research on pathfinding cognition in complex underground public space utilizing eye movement and EEG synchronous detection

Abstract

The complex underground public space brings challenge on pathfinding cognition. This research took Luoxiong Road Station in Wuhan as experimental site, using eye movement and electroencephalogram (EEG) synchronous detection, through pathway analysis and space-time fault method, exploring relationship between pathfinding cognition and complex underground public space. It was found that pathfinding habits and pathfinding decision-making were mainly affected by personal factors and environmental factors, respectively. Pathfinders influenced by personal factors, had behaviors such as left-walking or right-walking tendency, and the ratio of brain wave β/α was low (impression ratio ≤1). Pathfinders influenced by environmental factors, interested in the other side situation, vertical traffic and so on, and the ratio of brain wave β/α was high (impression ratio >1), with the frontal and parietal occipital lobe regions of brain being more active. These conclusions provided theoretical and data supplements for underground rail transit environment optimizing design in future.
