Laboratory Experiment Based Studies On Effect Of Peripheral Source On OnAxis Visual Performance

Abstract

The behavioural relationship among peripheral vision and onaxis vision is a very important parameter required to be investigated thoroughly. In this paper the influence of peripheral vision on onaxis vision has been investigated in a controlled environment. One behavioural experimentbased studies have been carried out to validate the relationship rigidly. In this experiment, the effect of peripheral vision on onaxis performance of a driver in a motorized road is a very important parameter considered. In this simulationbased study a driver simulator is used. There is a peripheral controlled glare source, which has been introduced at offaxis with respect to the line of sight. The glare source contrast (positive and negative) with respect to the background has been changed gradually and all the subjects (drivers) were made occupied with an onaxis task. The detection of peripheral glare source with respect to the onaxis performance of the subjects (drivers) has been recorded as detection time and also the number of misses for identifying the peripheral source.
