Abstract
Target selection is a crucial task in augmented reality (AR). Recent evidence suggests that user motion can significantly influence target selection. However, no systematic research has been conducted on target selection within varied intensity user motions and AR settings. This paper was carried out to investigate the effects of four user motions (i.e., standing, walking, running, and jumping) and two viewing modes (i.e., viewpoint-dependent and viewpoint-independent) on user performance of target selection in AR. Two typical selection techniques (i.e., virtual hand and ray-casting) were utilized for short-range and long-range selection tasks, respectively. Our results indicate that the target selection performance decreased as the intensity of user motion increased, and users demonstrated better performance in the viewpoint-independent mode than in the viewpoint-dependent mode. We also observed that users took a longer amount of time to select targets when using the ray-casting technique than the virtual hand technique. We conclude with a set of design guidelines to improve the AR target selection performance of users while in motion.
目标选择是增强现实(AR)中的一项重要任务。最近的证据表明,用户运动会对目标选择产生重大影响。然而,目前还没有针对不同强度的用户运动和 AR 设置下的目标选择进行过系统研究。本文研究了四种用户运动(即站立、行走、跑步和跳跃)和两种观看模式(即视点依赖型和视点无关型)对用户在 AR 中选择目标表现的影响。两种典型的选择技术(即虚拟手和光线投射)分别用于短距离和长距离选择任务。我们的研究结果表明,随着用户运动强度的增加,目标选择性能也随之降低,用户在视点无关模式下的表现要好于视点相关模式下的表现。我们还观察到,与虚拟手技术相比,用户在使用光线投射技术时需要更长的时间来选择目标。最后,我们提出了一套设计指南,以提高用户在运动中的 AR 目标选择性能。
