Study on the influence of safety signs on people's attention based on intelligent eye tracker

This article uses eye tracker to record the subjects' corresponding experimental data, and analyzes the influence of location settings on the significance of safety signs. This article discusses the effect of the location of the signs on the significance of the safety signs. This study used eye movement and reaction time methods to investigate the hazard perception ability of young drivers in special road environments. This research hypothesizes that having traffic safety signs will promote the driver's reaction time to hazards, but the safety signs will not speed up the driver's visual search time for hazards. With the help of eye tracker, 30 subjects were recorded when they identified the safety signs at 6 locations. Combined with Tobii's visual analysis and statistical analysis, the fixation duration was used as a quantitative indicator for the participants to evaluate the significance of safety signs. The results show that when the safety signs are set on the right or upper right, the red area in the heat map of the visualization analysis is larger and more concentrated, and the number of fixation points in the area of interest is larger. This position can better enhance the distinctiveness of the safety signs.
