Development of a General Model of the Car Drivers' Eye Movement Sequences and Effects of Subject and Environmental Variables

Abstract

Abstract : The present study represents the continuation of past research on the driver's eye movement behavior. Previous experiments yield to describe the driver's eye movement behavior in terms of time discrete process models. The established models were not perfectly accurate in predicting the driver's future fixations of the eye. The current goal was, first, to study whether any previous presupposition was not fulfilled, or whether, secondly, there exists some upper limit regarding the causal relationship between the successive fixations of the eye. The conducted experiments empirically support the validity of the prepositions. The results also yield that a driver's visual search depended on his long-term variables. The observed eye movement behavior represented a visual adaptation to the environmental conditions. The degree of adaptation depended, however, on the individual's capabilities.
