Abstract

Virtual Reality (VR) offers a unique collaborative experience, with parallel views playing a pivotal role in Collaborative Virtual Environments by supporting the transfer and delivery of items. Sharing and manipulating partners' views provides users with a broader perspective that helps them identify the targets and partner actions. We proposed TeamPortal accordingly and conducted two user studies with 72 participants (36 pairs) to investigate the potential benefits of interactive, shared perspectives in VR collaboration. Our first study compared ShaView and TeamPortal against a baseline in a collaborative task that encompassed a series of searching and manipulation tasks. The results show that TeamPortal significantly reduced movement and increased collaborative efficiency and social presence in complex tasks. Following the results, the second study evaluated three variants: TeamPortal+, SnapTeamPortal+, and DropTeamPortal+. The results show that both SnapTeamPortal+ and DropTeamPortal+ improved task efficiency and willingness to further adopt these technologies, though SnapTeamPortal+ reduced co-presence. Based on the findings, we proposed three design implications to inform the development of future VR collaboration systems.
TeamPortal:通过共享和操纵并行视图探索虚拟现实协作。
虚拟现实(VR)提供了一种独特的协作体验,通过支持物品的转移和交付,并行视图在协作虚拟环境中发挥着关键作用。共享和操纵合作伙伴的视图为用户提供了更广阔的视角,帮助他们识别目标和合作伙伴的操作。因此,我们提出了TeamPortal,并对72名参与者(36对)进行了两项用户研究,以调查交互式共享视角在VR协作中的潜在好处。我们的第一项研究比较了ShaView和TeamPortal在包含一系列搜索和操作任务的协作任务中的基线。结果表明,TeamPortal在复杂任务中显著减少了移动,提高了协作效率和社会存在。根据结果,第二项研究评估了三种变体:TeamPortal+、SnapTeamPortal+和DropTeamPortal+。结果表明,SnapTeamPortal+和DropTeamPortal+都提高了任务效率和进一步采用这些技术的意愿,尽管SnapTeamPortal+减少了共同存在。基于这些发现,我们提出了三个设计启示,为未来VR协作系统的发展提供信息。
