Analysis of the Influence of VR Technology Based on Big Data Edge Computing and Deep Learning on Short Video Teaching

“…Big data edge computing can improve the data security and privacy protection of VR applications, and data processing and analysis on Internet edge devices can reduce the security risks in data transmission and protect users' privacy information. Big data edge computing can also reduce the energy consumption cost of VR applications and the effective utilization of computing resources; thus, will effectively reduce the operation cost of short video teaching [4]. These advantages will effectively promote the improvement of the teaching quality of short videos and the popularization of the application, and also provide a good opportunity for the further development and application of big data edge computing technology.…”
