预计在不久的将来，在2级或3级自动驾驶汽车的接管阶段，驾驶员将面临脆弱性。我们关注的问题是，当驾驶员从自动模式接管控制权时，警惕性下降，注意力难以转移。为了解决这个问题，我们探索了“VACT（视觉辅助概念接管）”，它应用动态来转移视觉注意力。通过全面的文献回顾，我们提出了两个挡风玻璃接口概念，以提高驾驶员在接管前的警惕性和准备程度：有用视场（UFOV）和物体视图（OV）接口。为了评估UI概念，57名参与者在半自然驾驶环境中进行了室内实验。讨论了视觉辅助界面设计的意义及其对制动反应时间、心理负荷和感知有用性的影响。
In the near future, drivers are expected to face vulnerability under the takeover phase in automated cars of level 2 or 3. We focused on the problem resulted from decreased vigilance and difficulties in shifting attention while drivers take over the control from the automatic mode. In order to address this problem, we explored "VACT (Visual Assistance Concept for Takeover)", which applies dynamicity to shift visual attention. From a thorough literature review, we have come up with two windshield interface concepts to enhance drivers' vigilance and readiness before the takeover: Useful Field of View (UFOV) and Object-View (OV) Interface. To evaluate the UI concepts, an in-lab experiment was conducted with 57 participants in a semi-naturalistic driving environment. Implications for interface design of visual assistance and its impact on brake reaction time, mental workload and perceived usefulness are discussed.
