A Review of Occlusion as a Tool to Assess Attentional Demand in Driving

Objective The aim of this review is to identify how visual occlusion contributes our understanding attentional demand and spare capacity in driving the strengths limitations method. Background technique was developed by John W. Senders evaluate driving. Despite its utility, it has been used infrequently driver attention/inattention research. Method Visual studies published between 1967 2020 were reviewed. focus on original which forward field intermittently occluded while participant Results Occlusion have shown that varies across situations drivers indicated environmental, situational, inter-individual factors behind variability. complements eye tracking being able indicate temporal requirements for redundancy information sampling. proper selection settings depends target Conclusion Although there are a number looking at various aspects demand, we still only beginning understand these demands vary, interact, covary naturalistic Application findings methodological theoretical implications human research development distraction monitoring in-vehicle system testing. Distraction detection algorithms testing guidelines should consider variability drivers’ situational individual capacity.
