Abstract

When using Virtual Reality (VR) and Augmented Reality (AR) to support remote collaboration, effective communication between a remote expert in VR and a local worker in AR is important for guiding and following task instructions. This is especially crucial for assembly tasks, which require precise identification of parts and clear directions for their combination. Despite the increasing interest in efficient VR-AR communication methods, previous studies have been limited to complex hardware setups and simplified assembly tasks. In this research, we introduce a communication approach for remote collaboration in complex assembly tasks, utilizing simplified hardware configurations. We conducted a user study (n=30) and compared three interaction interfaces (hand gestures, 3D drawing, and virtual replicas) in task completion time, subjective questionnaires, and preference rank. The results showed that the use of virtual replicas not only enhances task efficiency but also receives strong preference by users. These findings indicate that virtual replicas can provide intuitive instructions to local workers, resulting in a clearer understanding of the expert’s guidance.

在 XR 远程协作中使用虚拟副本的高效 VRAR 通信方法
在使用虚拟现实(VR)和增强现实(AR)支持远程协作时,VR 中的远程专家和 AR 中的本地工人之间的有效沟通对于指导和遵循任务指示非常重要。这一点对于装配任务尤为重要,因为装配任务需要精确识别部件并提供清晰的组合指示。尽管人们对高效的 VR-AR 通信方法越来越感兴趣,但以往的研究仅限于复杂的硬件设置和简化的装配任务。在本研究中,我们利用简化的硬件配置,为复杂装配任务中的远程协作引入了一种通信方法。我们进行了一项用户研究(n=30),比较了三种交互界面(手势、三维绘图和虚拟复制品)的任务完成时间、主观问卷和偏好等级。结果表明,使用虚拟复制品不仅能提高任务效率,还能获得用户的强烈偏好。这些研究结果表明,虚拟复制品可以为当地工人提供直观的指示,使他们更清楚地理解专家的指导。

期刊介绍: The International Journal of Human-Computer Studies publishes original research over the whole spectrum of work relevant to the theory and practice of innovative interactive systems. The journal is inherently interdisciplinary, covering research in computing, artificial intelligence, psychology, linguistics, communication, design, engineering, and social organization, which is relevant to the design, analysis, evaluation and application of innovative interactive systems. Papers at the boundaries of these disciplines are especially welcome, as it is our view that interdisciplinary approaches are needed for producing theoretical insights in this complex area and for effective deployment of innovative technologies in concrete user communities. Research areas relevant to the journal include, but are not limited to: • Innovative interaction techniques • Multimodal interaction • Speech interaction • Graphic interaction • Natural language interaction • Interaction in mobile and embedded systems • Interface design and evaluation methodologies • Design and evaluation of innovative interactive systems • User interface prototyping and management systems • Ubiquitous computing • Wearable computers • Pervasive computing • Affective computing • Empirical studies of user behaviour • Empirical studies of programming and software engineering • Computer supported cooperative work • Computer mediated communication • Virtual reality • Mixed and augmented Reality • Intelligent user interfaces • Presence ...
