An Analysis of Effect of Lateral Viewing on Visual Perception of Road Space

Abstract

Lateral viewing where the directions of the head and eyes are different and the change of the lateral viewing with time interferes with attentive visual search performance because visual attention resources are divided and coordinated into head and eye directions. In this study, we hypothesize that lateral viewing and the change of the viewing affects the duration required for visual perception of road space. Specifically, we focus on the lateral viewing of pedestrians when they cross a road and analyze the effect of the lateral viewing and the change of the viewing on the search time for a target stimulus in the road space by conducting a visual search task. The results showed that the longer the time required to search time for target stimulus in the road space, the greater the lateral viewing and the greater the change of the lateral viewing with time. The results supported the above hypothesis.
