AI总结：
本文提出Portobello平台，将实验室驾驶模拟研究移植到真实道路，实现物理-虚拟孪生研究，并通过N=32的自动驾驶人行横道合作研究验证了其可移植性与有效性。
摘要：
在汽车用户界面设计中，测试通常从基于实验室的驾驶模拟器开始，并逐步转向道路研究以降低风险。混合现实（XR）有助于将虚拟研究设计转化为真实道路，以提高生态效度。然而，由于在物理和虚拟世界中复制研究的挑战，研究人员很少在实验室和道路模拟器中运行相同的研究。为了提供将实验室研究设计移植到道路上的通用基础设施，我们构建了一个平台可移植的基础设施Portobello，使我们能够运行孪生的物理-虚拟研究。作为概念验证，我们用Portobello扩展了道路模拟器XR-OOM。我们在实验室和道路上运行了一项被试内、自动驾驶车辆人行横道合作研究（N=32），以调查研究设计的可移植性以及平台驱动对研究结果的影响。据我们所知，这是首个能够将最初为实验室模拟器设计的研究孪生到道路平台上执行的系统。
英文摘要：
In automotive user interface design, testing often starts with lab-based driving simulators and migrates toward on-road studies to mitigate risks. Mixed reality (XR) helps translate virtual study designs to the real road to increase ecological validity. However, researchers rarely run the same study in both in-lab and on-road simulators due to the challenges of replicating studies in both physical and virtual worlds. To provide a common infrastructure to port in-lab study designs on-road, we built a platform-portable infrastructure, Portobello, to enable us to run twinned physical-virtual studies. As a proof-of-concept, we extended the on-road simulator XR-OOM with Portobello. We ran a within-subjects, autonomous-vehicle crosswalk cooperation study (N=32) both in-lab and on-road to investigate study design portability and platform-driven influences on study outcomes. To our knowledge, this is the first system that enables the twinning of studies originally designed for in-lab simulators to be carried out in an on-road platform.
