Driving a car involves a variety of perceptual, cognitive and motor tasks. It is an activity that is becoming increasingly more complex due to growing traffic as well as modern technology. To describe the cognitive processes involved in driving a car, an important tool is modeling.
The purpose of the project, which led to this thesis, was to investigate the possible effects different horizontal Fields of View (FoV) have on driving performance when driving at night with a Vision Enhancement System (VES). The FoV chosen to be examined were 12 degree and 24 degree FoV, both displayed on a screen with the horizontal size of 12 degree FoV…
