The Study Of Inattentional Blindness In Augmented Reality Head-up Display System Assisted Driving

With the continuous development of science and technology,the application of augmented reality technology in people's lives is increasing.Many studies have shown that augmented reality technology also has shortcomings,such as the phenomenon of inattentional blindness.Driving tasks are closely related to safety,so the phenomenon of inattentional blindness in driving has also attracted the attention of researchers.Many studies have shown that inattentional blindness in driving is related to factors such as workload,type of stimulus,location of stimulus.Augmented Reality Head-Up Display System(Augmented reality head-up display,AR-HUD),as a common application of augmented reality technology in assisting car driving tasks,has been applied to many brands of cars and is still evolving.Based on previous studies,this study explores the impact of AR-HUD on driver's inattentional blindness in driving tasks,and further explores its influencing factors such as workload,stimulus location and relative position of AR prompts and stimulus.This study aims to provide theoretical basis and reference for the future AR-HUD design and application,to reduce the driver's non-attention blindness when using AR-HUD,and to improve driving safety.The study consists of two parts:Study 1 explores the effects of different enhancements on inattentional blindness in car driving.The study included Experiment 1 and explored the effects of non-enhancement,unexpected stimulus enhancement,and unexpected stimulus without enhancement in the two scenarios of AR-HUD and AR-HUD,and the impact on inattentional blindness in car driving.Study 2 explores the influencing factors of inattentional blindness in AR-HUD vehicle driving.The study includes Experiment 2 and Experiment 3.Experiment 2 explores the impact of workload on inattentional blindness in driving tasks where AR-HUD is used and unexpected stimulus is not enhanced.Experiment 3 explores the effect of the stimulus position and the relative position of the AR cue and stimulus on inattentional blindness in driving tasks where AR-HUD is used and unintended stimulus is not enhanced.This study led to the following main conclusions:(1)The subjects who used AR-HUD had significantly less inattentional blindness when the unexpected stimulus was enhanced,and those who did not use AR-HUD,but who were not enhanced in the unexpected stimulus had significantly more inattentional blindness than that of the subjects who did not use AR-HUD.(2)When the subject used AR-HUD and the unexpected stimulus was not enhanced,the workload affected the inattentional blindness of the subject.Higher workloads lead to more inattentional blindness.(3)When the subject used AR-HUD and the unexpected stimulus was not enhanced,the position of the unexpected stimulus and the relative position of the AR prompt box and the stimulus would affect the inattentional blindness of the subject.When unexpected stimulus appear on both sides of the road,the AR prompt box overlaps with the stimulus to cause more inattentional blindness;when the unexpected stimulus appear in the center of the road,the overlap of the AR prompt box with the stimulus reduces the occurrence of inattentional blindness.
