The current AR-HUD can display more and more information, which may lead to an increase in the driver’s visual perceptual load. Taking pedestrian warning as an entry point, this study adopts a 2 (with or without AR-enhanced cues, between subjects) × 2 (congestion level, within subjects) × 2 (pedestrian location, within subjects) three-factor mixed experimental design based on a simulated driving video to explore the visual complexity accompanying AR-HUD warning displays on drivers' visual attention and behavioral performance when perceiving unexpected stimuli in different locations in congestion level scenarios. The main findings are: 1) Drivers with AR cues will perceive and respond to unexpected pedestrian stimuli faster. 2) Drivers will respond faster to unexpected pedestrians in crowded conditions, and AR warnings can improve visual search efficiency in this state.展开更多
