A Study on the Right Position for Installation of a Visual Display While Driving

The aim of this study is to explore the right position for installation of a visual display of CarNavigation system. The method of this research is to consider about the effects of installing a display on the visual information processing of driver from the experimental approach . The evaluation indices are measuring the saccadic time, the stationary time and the visibility time from the movement of the subject's fixation point. The results shows following : (1) It is proved statistically that the position for installation of a display effects the saccadic time , the stationary time and visibility time. In addition, the longer the distance from the glabller point to the position for installation of a display becomes, the bigger the visibility time is . (2) The reason why the effect of the vertical installation angle on the visibility time is lager than that of horizontal is dependent on a property of the saccadic movement and the region of the useful field of view. (3) The estimated equation that shows the relationship between the position for installation of a display and the visibility time is proposed.
