We investigated the efficacy of a novel augmented reality (AR) navigation display called Mirror in the Sky (MitS). AR displays can reduce the distance between virtual imagery content and the user's view of the environment but may have limited benefit for depicting map-based survey information. MitS presents a simulated mirror in the upper visual field, which reflects the topographic layout of the terrain in front of the user. In our experiment, 28 participants used MitS and a track-up Map in virtual reality to perform a task, which required participants to decide whether a route could be successfully navigated. A post-trial recall task examined spatial awareness. On that task, accuracy, duration, and subjective workload measures favoured the Map. However, participants with virtual reality experience made more accurate route confirmation decisions with MitS than the Map. We compared an augmented reality display called Mirror in the Sky (MitS) to a conventional electronic map for route confirmation and threat location tasks. Although the electronic map showed advantages over MitS on some measures, users with some VR experience performed route confirmation more accurately with MitS than a map.
我们研究了一种名为“天空之镜”（MitS）的新型增强现实（AR）导航显示器的疗效。AR 显示器可以缩小虚拟图像内容与用户对环境的观察之间的距离，但在描绘基于地图的调查信息方面可能益处有限。MitS 在视野上方呈现一个模拟的镜子，反映用户前方地形的地形布局。在我们的实验中，28 名参与者在虚拟现实中使用 MitS 和向上跟踪的地图来执行一项任务，该任务要求参与者判断路线是否可以成功导航。一项试验后回忆任务考察了空间意识。在该任务中，准确性、持续时间和主观工作量指标都偏向于地图。然而，有虚拟现实经验的参与者使用 MitS 做出的路线确认决策比地图更准确。我们将一种名为“天空之镜”（MitS）的增强现实显示器与传统电子地图进行了比较，以确认路线和定位威胁。尽管电子地图在某些指标上优于 MitS，但有一些 VR 经验的用户使用 MitS 进行路线确认比地图更准确。
