SUBJECTIVE EVALUATION OF DRIVER'S EYE-MOVEMENT DURING BLOWING SNOW

Abstract

This paper describes evaluation of driver's eye-movement in reduced visiblility conditions due to blowing snow. Driver'eye-movement is evaluated by following methods.
(1) Fixation duration, angular velocity, three-dementional coordinatesand frequency distribution of fixation points in reduced visibility conditions are estimated from driver's fixed points.
(2) Driver's visual field under blowing snow condition can be defined by the concept of ‘Fuzzy’. We tryto estimate driver's eye-movement behavior by use of a ‘Fuzzy Entropy’, which is the expectation of an amount of information.
