摘要:

视觉线索在计算机介导的交流中至关重要。当通信发生在需要将多个用户的注意力集中在一个特定对象以及其他类似对象的协作场景中时,这一点尤为重要。本文探讨了协同定位增强现实(AR)协作中视觉提示对指向任务的影响。用户研究(N = 32,16对)进行比较两种类型的视觉线索:指向线(PL)和移动轨迹(MT)。通过对不同状态(静态和动态)和密度(低、中、高)物体的一系列协作指向任务的测试,结果表明,PL在任务性能和可用性方面优于MT,而MT在社会存在感和用户偏好方面优于PL。基于我们的研究结果,提供了一些设计的启示指向任务在协同定位的AR协作。

英文摘要:

Visual cues are essential in computer-mediated communication. It is especially important when communication happens in a collaboration scenario that requires focusing several users' attention on aspecific object among other similar ones. This paper explores the effect of visual cues on pointing tasks in co-located Augmented Reality (AR) collaboration. A user study (N = 32, 16 pairs) was conducted to compare two types of visual cues: Pointing Line (PL)and Moving Track (MT). Both are head-based visual techniques.Through a series of collaborative pointing tasks on objects with different states (static and dynamic) and density levels (low, mediumand high), the results showed that PL was better on task performance and usability, but MT was rated higher on social presenceand user preference. Based on our results, some design implicationsare provided for pointing tasks in co-located AR collaboration.
