多人网络虚拟现实儿童科普系统的设计研究

Research on Design of Multiplayer Network Virtual Reality Children’s Popular Science Education System

针对传统儿童科普教育存在的沉浸感薄弱、知识传输方式单一的问题,设计基于多人网络虚拟现实(VR)技术的儿童科普系统。系统的设计采用模块化的构建方式,主要分为网络联机模块和虚拟现实科普教育业务控制模块。在网络联机模块中,建立起服务器,教师机,学生机之间的信息通信,实现多人信息的加载和多人空间位置的实时同步。虚拟现实科普教育业务控制模块主要包括场景加载模块、知识讲解模块、VR交互模块以及答题模块。系统运行时教师通过虚拟现实交互面板发出指令,控制场景的加载,把握整体教学进度,并与学生的虚拟角色答题互动。学生通过与虚拟场景的交互,完成教师安排的任务,获取科普知识。实验结果表明,该系统应用于儿童科普教学过程,有利于提升儿童的学习积极性和知识吸收效率。同时,这种多人网络的虚拟现实系统的设计方法也可以推广至其他教育教学领域。

To improve the weakness of immersion and monotonous teaching in traditional children’s popular science education, a children’s popular science education system based on multiplayer network virtual reality(VR) technology is designed. The design of the system adopts modular construction, which is mainly divided into network online module and VR popular science education control module. In the network online module, the information communication between the server, the teacher machine and the student machine is established to realize the loading of multi-user information and the real-time synchronization of multi-user space location. The VR popular science education control module mainly includes scene loading module, knowledge introduction module, VR interaction module and answer module. The teacher issues instructions through the VR interactive panel when the system runs, controls the loading of scenes, grasps the overall teaching progress, and interacts with students’ virtual characters to answer questions. Students complete the tasks arranged by the teacher in the virtual scene and acquire popular science knowledge. The experiment shows that this system is conducive to improving children’s learning enthusiasm and knowledge absorption efficiency in the process of children’s popular science education. At the same time, this multi-person network virtual reality system design method can also be extended to other education and teaching fields.
