Samenvatting
To elucidate the possible traffic safety risks induced by visual field defects, a method has been developed based on a driving simulator. On a screen quadratic light ' stimuli of three different sizes are generated, one at a time, in any of 24 different positions. The latency between stimulus appearance and braking is measured. Among the subjects with visual field defects the individual variations are very dominant. Most subjects do not compensate the deficiency.
