Digital mirrors within vehicles may improve aerodynamics and the field of view. Nevertheless, digital technology may fail. This study investigated the influences of different failures on distraction and behavioural adaptation, measured using glance and driving behaviour, as well as a workload questionnaire. Three failure conditions included a blank (no information), a degraded (hard to extract information), and a frozen (misleading information) display. In a high-fidelity simulator, 30 participants undertook three drives in a UK motorway scenario. During the second drive, the right (offside) digital mirror failed during the instruction to conduct a left–right lane-change manoeuvre, and remained until the end of that drive. Results show that failures led to longer and more glances towards the driver-side mirror, increased variability of speed and lateral position, and heightened workload; however, these distracting and behavioural effects lessened in future drives. Behavioural adaptations in the form of increased rear-view mirror or blind-spot checks could not be established. There were indications that the blanked mirror affected workload less than the other failures.

遇到数字式后视镜故障时，了解驾驶员的注意力和行为适应

车辆内的数字镜可改善空气动力学和视野。但是，数字技术可能会失败。这项研究调查了不同故障对注意力和行为适应的影响，使用了视线和驾驶行为以及工作量调查表进行了测量。三种故障情况包括空白（无信息），降级（难以提取信息）和冻结（误导性信息）显示。在高保真模拟器中，有30名参与者在英国高速公路场景中进行了3次驾驶。在第二次驾驶期间，右（越位）数字镜在执行左右换道操作的指令期间失败，并一直保持到该驾驶结束。结果表明，故障导致对驾驶员侧后视镜的视线越来越长，速度和横向位置的可变性增加，工作量增加；但是，这些分散的注意力和行为影响在以后的驱动中有所减轻。无法建立以增加后视镜或盲点检查形式的行为适应。有迹象表明，空白镜像对工作负载的影响小于其他故障。
