在物理和虚拟环境中，寻找特定对象都是基本任务之一。然而，视觉扫描大的场景可能是低效和令人沮丧的，特别是当目标是在一个人的视野之外。因此，已经有几项研究支持在三维环境中使用各种视觉线索的目标寻找任务。然而，大多数研究都侧重于向使用者传达目标的相对位置或距离。在这项研究中，我们提出了PanoCue，这是一种视觉线索，它覆盖了用户视野中心的周围全景视图，用于在3D空间中根据用户的位置和头部方向传达目标的位置和距离。为了评估，我们对20名参与者进行了一项用户研究，要求他们在不同的视觉线索条件下找到目标：PanoCue、Radar、Arrow和没有线索的基线。结果，我们发现视觉线索的存在提高了任务表现，PanoCue显著缩短了旅行距离。调查结果还显示，我们的反馈设计在易用性、疲劳性和满意度方面获得了积极的评价。
Finding a specific object is one of the basic tasks in both physical and virtual environments. However, visually scanning large scenes can be inefficient and frustrating, especially when the target is outside of one’s field of view. As a result, there have been several studies for supporting target finding tasks in a three-dimensional environment with various visual cues. However, most studies focused on conveying either the relative position or the distance of the target to users. In this study, we propose PanoCue, which is a visual cue that overlays a panorama view of the surroundings at the center of the user’s field of view for conveying both the position and the distance of a target in a 3D space with respect to the user’s location and head orientation. For evaluation, we conducted a user study with 20 participants where they were asked to find a target under different visual cue conditions: PanoCue, Radar, Arrow, and a baseline without cues. As a result, we found that the presence of visual cues improves task performance and that PanoCue significantly reduces the travel distance. Findings also showed that our feedback design received positive ratings in terms of easiness, fatigue, and satisfaction.
