Effects of E-Mirror Location and Size and Lane Change Direction on Lane Change Time, Eye-Off-Road Time, Mental Workload, and Preference

Electronic mirrors (E-mirrors) are camera-based mirrorless systems that have been considered as an alternative to conventional automotive rear-view mirrors. E-mirror location and size need be carefully determined provide safe preferred driving conditions. This study examined the effects of location, size, lane-change direction on lane change time, eye-off-road (EOR) mental workload, preference. In a fixed-base simulator, total 20 individuals (mean (SD) age = 24.7 (2.2) years) performed maneuvers under 12 different configurations, comprising 4 locations × 3 screen heights (6, 8, 9.7 cm; width-to-height aspect ratios 16:9). significantly affected EOR preference, whereas preference only. Lane-change with right demanding more time workload. Considering E-mirrors 8 cm high or higher should positioned near sides steering wheel bottom front inner pillars. The relevance these findings ergonomic design guidelines is discussed.
