Abstract
Objective: The evaluation of driving performance is conducted on the CMS and the rear view of the side during the driving of the actual vehicle, and an improvement plan is proposed for CMS.BRBRBackground: Rearview mirrors play an essential role in the vehicle (especially in cars) while taking reverse, parking, and changing lanes. Current cars are equipped with many safeguards (cruiser functions, autonomous driving, lane departure prevention, etc.) to help drivers. The camera monitoring system (CMS) has been used as one of the rearview mirrors in recent times. However, the visual acuity while using CMS is not considered enough in ergonomics research.BRBRMethod: Thirty subjects without any eye diseases took part in this study. An experiment was performed with two vehicles installed with a rearview mirror and another with CMS. To compare the two conditions fixation time and saccade time were evaluated.BRBRResults: Overall, using CMS required lower fixation time and saccade time than the conventional rearview mirror. All these results showed that CMS requires less cognitive load than rearview mirrors.BRBRConclusion: There were problems with glare and distance, and there was no sign of caution in the available rearview mirror in CMS. BRBRApplication: If the problems and cautions about future glare and distance are solved and applied, it will be the design of a safer CMS.
