HEADMOVEMENTS OF DRIVERS: COMPENSATORY HEAD MOVEMENTS DUE TO RESTRICTIONS IN THE VISUAL FIELD

This report is the second in a series dealing with head movements as an indicator of attention distribution of drivers in traffic situations. In order to study the way restrictions of the visual field affected the scanning behaviour of drivers registrations of head movements were made in urban road crossings. Four subjects drove in real traffic wearing spectacles that restricted their visual fields of fixations. Three different levels of restriction of the visual field of fixations were chosen, corresponding to a maximum binocular visual field of 80, 65, and 50 degrees, respectively. Maximum amplitude of horizontal head movements was used as the main dependent variable. The subjects were found to change their systematic scanning behaviour due to restrictions in their visual fields, by making correspondingly longer horizontal head movments. The subjects did not drive significantly slower neigher did they express any feelings of insecurity when driving with a restricted visual field. /Author/
