摘要
提出一种基于VR的大数据可视化教学系统的实现方法。给出了大数据可视化教学系统设计原则,基于并行实时渲染的大规模无缝拼接显示技术、数据可视化的多体感交互技术、大屏的视频点播技术、面向大数据可视化的全景拼接与显示等,提出了大数据可视化教学系统架构;给出了大数据分析过程的认知模型、高维数据的分析及呈现方法,以及基于可视化的数据理解与可用性分析评估。利用Unity3D技术,通过C#等开发了大数据可视化虚拟课堂。实践证明,该系统可有效提高学生的学习兴趣及效率,增强学生对于大数据本质的洞察和理解。
In this paper, an implementation method and design principles of big data visualization teaching system based on virtual reality are proposed. Based on the large-scale seamless splicing display technology of parallel real-time rendering, the multi-body feeling interaction technology of data visualization, large screen video on demand technology, and the panoramic splicing and display technology for big data visualization, the architecture of the big data visualization teaching system is proposed. The cognitive model of big data analysis process is given. The analysis and presentation method of high-dimensional data is proposed,and the analysis and evaluation method of data understanding and availability based on visualization is explained. A virtual classroom of big data visualization is developed through Unity3D and c#, etc. The practice has proved that the system can effectively improve students’ interest and efficiency in learning, and enhance students’ insight and understanding of the big data essence.
