摘　　要：目前现有虚拟现实直播系统难以满足课堂教学的需求。设计并实现一套基于虚拟现实直播的多人网络教学系统。通过对虚拟现实直播在媒体资源以及多人交互方面进行增强,使得系统满足课堂教学的基本需求,利用虚拟现实特性打造沉浸式体验。系统支持图片、视频、网页和三维模型资源,在虚拟现实直播教学过程中动态地加载与交互,提升了教学环节的完备性;设计一套应用于虚拟现实直播教学的多人互动方法,以满足虚拟现实教学过程中协同观看和教学反馈的需求。实验结果表明,该系统能够较好地实现直播教学过程中媒体资源使用、多人协同观看和学生视线反馈。The current virtual reality video streaming system is difficult to meet the needs of classroom teaching.A multi-user network teaching system based on virtual reality video streaming has been designed and implemented.By enhancing the virtual reality video streaming in terms of media resources and multi-user interaction,the system met the basic needs of classroom teaching and used virtual reality features to create an immersive experience.The system supported pictures,videos,Web pages and three-dimensional model.It dynamically loaded and interacted in the virtual reality live teaching process,which improved the completeness of the teaching process.A set of multi-person interaction methods applied to virtual reality live teaching was designed to meet the needs of collaborative viewing and teaching feedback in the process of virtual reality teaching.The experimental results show that the system can effectively achieve the use of media resources,multi-person collaborative viewing and students’sight feedback during the live teaching process.
