Prediction of Cognitive Performance of Drivers using Eye Fixation Behaviours

The relationship between features of an elderly driver’s eye fixations and cognitive performance was analysed. The participants were 29 motorists aged over 60 years who drove frequently. Their eye movements were observed during 16 specific situations along a test course. Their cognitive performance was measured using computer based tests prior to driving. Since some features of eye fixations during driving correlate with the scores of cognitive tests, the possibility of predicting the cognitive scores was examined using features of eye fixations and a multiple regression analysis technique. Prediction performance was also affected by specific features of the fixations and their behaviour.
