增强现实 (AR) 的一个重要应用是界面设计，可以显示用户视线之外的现实世界部分。此类界面的设计空间非常广阔，有许多选项可以将场景被遮挡部分的可视化集成到用户的主视图中。本文比较了四种用于去除遮挡的 AR 界面：X 射线、剖面图、画中画和多视角。在一项受试者内部研究 (N = 33) 中，对四个任务的接口进行了比较：计算动态球体、指向被遮挡人的方向、查找与给定对象最接近的对象以及查找匹配数字对。结果表明，在用户需要同时看到遮挡物和被遮挡物的任务中，Cutaway 会导致性能不佳；画中画和多视角相对于剖面图和X射线具有可视化全面性优势，但在方向引导方面存在劣势；由于可视化的复杂性，X 射线在任务完成时间上存在劣势；参与者对剖面图和画中画的可用性评分较高，对多视角和 X 射线的可用性评分较低。
An important application of augmented reality (AR) is the design of interfaces that reveal parts of the real world to which the user does not have line of sight. The design space for such interfaces is vast, with many options for integrating the visualization of the occluded parts of the scene into the user's main view. This paper compares four AR interfaces for disocclusion: X-ray, Cutaway, Picture-in-picture, and Multiperspective. The interfaces are compared in a within-subjects study (N = 33) over four tasks: counting dynamic spheres, pointing to the direction of an occluded person, finding the closest object to a given object, and finding pairs of matching numbers. The results show that Cutaway leads to poor performance in tasks where the user needs to see both the occluder and the occludee; that Picture-in-picture and Multiperspective have a visualization comprehensiveness advantage over Cutaway and X-ray, but a disadvantage in terms of directional guidance; that X-ray has a task completion time disadvantage due to the visualization complexity; and that participants gave Cutaway and Picture-in-picture high, and Multiperspective and X-ray low usability scores.
