Visual information processing characteristics of drivers in prediction of dangerous situation - Comparison among novice, expert and non-licensed person -

Abstract

The aim of this study was to examine the difference of visual information processing in KYT (Kiken Yochi Training) among novice, expert and non-licensed persons. In KYT tasks, participants were required to search for a potentially dangerous part using a static image under driving situations. The location of fixation point and the time series change of eye gaze were measured using an eye camera. In order to detect the difference of visual information processing among three groups above, an important area that the participants must pay attention to with the highest priority was set for each static image. The time until the eye gaze fixates to the important area, and the ratio of the fixation time to the total search time were detected. Using these measures, the difference of visual information processing among three groups was clarified. Moreover, for novice and non-licensed participants, it was also explored whether a lecture related to KYT would improve the efficiency of visual information processing. The time until the eye gaze fixates to the important area was longer for the non-licensed participants than for the experienced participants. The learning effect by means of a KYT lecture was also observed
