As more people meet, interact, and socialize online, Social Virtual Reality (VR) emerges as a technology that bridges the gap between traditional face-to-face and online communication. Unlike traditional screen-based applications, Social VR provides immersive, spatial, and three-dimensional social interactions, making it a potential tool for enhancing remote collaborations. Despite the growing interest in Social VR, research on its role in collaboration remains fragmented, calling for a synthesis to identify research gaps and future directions. We conducted a 20-year scoping review, screening 2,035 articles and identifying 62 articles that addressed how Social VR has supported collaboration. Our analysis shows three key levels of support: Social VR can enhance individual perceptions and experiences within their groups, foster team dynamics with virtual elements that enable realistic interactions, and employ the unique affordances of VR to augment users' spaces. We discuss how future research in Social VR should move beyond replicating physical-world interactions and explore how immersive environments can cultivate long-term collaboration, trust, and more diverse and inclusive participation. This review highlights the current practices and challenges, highlighting new opportunities for theorizing and designing Social VR systems that responsibly support remote collaborations.

翻译：随着越来越多的人在线上会面、互动和社交，社交虚拟现实（VR）作为一种弥合传统面对面交流与在线沟通之间差距的技术应运而生。与传统的基于屏幕的应用不同，社交VR提供了沉浸式、空间化和三维的社交互动，使其成为增强远程协作的潜在工具。尽管对社交VR的兴趣日益增长，但关于其在协作中作用的研究仍然零散，亟需进行综合以识别研究空白和未来方向。我们进行了一项为期20年的范围综述，筛选了2,035篇文章，并确定了62篇探讨社交VR如何支持协作的文章。我们的分析揭示了三个关键的支持层面：社交VR可以增强个体在其群体内的感知和体验，通过虚拟元素促进团队动态以实现逼真的互动，并利用VR的独特可供性来扩展用户的空间。我们讨论了未来社交VR研究应如何超越对物理世界互动的简单复制，并探索沉浸式环境如何能够培养长期协作、信任以及更多样化和包容性的参与。本综述强调了当前的实践与挑战，并指出了理论化和设计能够负责任地支持远程协作的社交VR系统的新机遇。
