虚拟学习环境（VLE）是旨在通过在线平台远程教育学生群体的空间。虽然传统的VLE在教育学生方面表现出了希望，但它们提供的沉浸感有限，总体上降低了学习效率。在本文中，我们描述了vSocial，一个基于云的虚拟现实学习环境（VRLE）系统，可以部署在高速网络使用高保真“社交VR”平台。vSocial可灵活控制小组学习内容，并符合既定的VLE标准，同时为教师和学生提供更好的沉浸式用户体验。对于我们的vSocial开发，我们建立在现有特殊教育VLE的用例上，即，iSocial通过实施社会能力干预（SCI）课程来培训患有自闭症谱系障碍的青少年。vSocial可用于：（a）使用可穿戴VR技术实现多个学习模块，（B）集成认知状态传感设备，以及（c）使用托管在云资源上的Web应用程序安全地组织学习会话数据。我们的实验结果表明，vSocial中的VR内容交付模式比非VR课程更好地刺激了课程到真实的世界的泛化，并且与同等的桌面版本相比，提供了更好的沉浸感。此外，可用性研究结果表明，用户可以成功地使用vSocial中的Web应用程序功能进行小组学习活动，具有易用性和一致性。
Virtual Learning Environments (VLEs) are spaces designed to educate student groups remotely via online platforms. Although traditional VLEs have shown promise in educating students, they offer limited immersion that overall diminishes learning effectiveness. In this paper, we describe vSocial, a cloud-based virtual reality learning environment (VRLE) system that can be deployed over high-speed networks using the High Fidelity “social VR” platform. vSocial provides flexible control of group learning content and compliance with established VLE standards with improved immersive user experience for both instructor(s) and students. For our vSocial development, we build upon the use case of an existing special education VLE viz., iSocial that trains youth with Autism Spectrum Disorder by implementing the Social Competence Intervention (SCI) curriculum. The vSocial can be used to: (a) implement multiple learning modules using wearable VR technologies, (b) integrate cognitive state sensing devices, and (c) organize learning session data securely using web applications hosted on cloud resources. Our experiment results show that the VR mode of content delivery in vSocial better stimulates the generalization of lessons to the real world than non-VR lessons, and provides improved immersion when compared to an equivalent desktop version. Further, usability study results show that users can successfully use the web application features in vSocial for group learning activities with ease-of-use and consistency.
