Abstract:The increasing use of three-dimensional (3D) model-based workflows and the rapid advancement in computer-interface design and hardware have enabled technologies like virtual reality (VR) and augmented reality (AR) to support a variety of transportation use cases [1]. While VR provides a complete virtual replacement to the visual world, AR overlays or combines virtual and real elements in real time to produce a 3D, interactive view [1]. Milgram and Kishino (1994) defined the relationship between AR and VR along the reality-virtuality continuum, summarized in Figure 1. There are two basic categories of display types for these systems: handheld mobile devices, such as smartphones and tablets, and head-mounted display (HMD) devices, such as headsets or glasses [2], as shown in Figure 2.
