Design of human-computer interaction system based on virtual reality and its application in the dissemination of study lodge culture

Virtual reality (VR) is an emerging computer environment that utilizes virtual environments to achieve virtual assembly. It has broad application prospects and important value in multiple fields. Interactivity is one of the main characteristics of virtual environments. In order to improve the intelligence of the cultural experience process in the "study lodge" and meet the dissemination of traditional Chinese culture among a wider audience, VR technology is introduced to design and apply an intelligent human-computer interaction system for the "study lodge" from both hardware and software aspects. Firstly, the hardware structure of the system was designed and MEMS measurement and communication equipment was determined. Secondly, with the support of hardware devices, VR technology is matched with PC terminals to establish an indoor 3D environment on the terminal devices. Communication between different servers and terminals is established to achieve the web embedding and "study lodge" communication control in 3D scenes. Using touch screen interaction as the interactive end of the human-computer interaction system, we adopt the method of developing human-computer interaction interfaces to design good interaction between multiple terminals. The user interface interaction function and virtual handwriting function were implemented in the Unity engine. Finally, the features of the collected data were extracted through human-computer interaction method, and the extracted features were input into the classifier for feature recognition, achieving human-computer interaction.
