Research And Application Of Human-Computer Interaction And Real-time Transmission Technology In Virtual Reality

Virtual reality is a research hotspot in recent years,and some key technical problems have not been completely solved.This paper studies the technology of human-computer interaction and real-time transmission in virtual reality.First of all,this paper introduces some application examples and implementation methods of gesture interaction in virtual reality scene,and takes the junior and senior high school chemistry experiments as the breakthrough point to carry on the instantiation application to the above technology.In the virtual chemistry experiments,this paper introduces the research status of the virtual experiments,then concludes that the gesture interaction has great advantages in the virtual experiments,carries on the design of the gesture interaction combined with the virtual chemistry experiments.In order to make these gestures better meet the requirements of the experiments.Finally,on this basis,the virtualization of the junior and senior high school chemistry experiments is developed.The development of virtual reality is inseparable from the development of virtual reality videos,the transmission of virtual reality videos is also a major obstacle to the development of virtual reality.Another main content of this paper is to analyze and study the design of the video coding standard H.265/HEVC sub-pixel motion estimation interpolation structure,a 24×24 estimation unit with 8 forms is proposed,and then further simplifies to only 3 types of estimation units to complete the implementation of all 24 prediction modes,which greatly reduces the control complexity.Through the tradeoff between coding efficiency and computational complexity of several search patterns,an extensible search pattern is formed.The interpolation pipeline structure with specific search order avoids the interruption of pipeline caused by sub-pixel motion estimation search order in the reference software HM,and greatly improves the throughput of the system.Virtual reality video with high resolution requirement can be transmitted in real time.On the basis of studying the above technologies,and combining the needs of our two projects,according to the standard writing method,we have compiled the " Information technology-The gesture interaction system-Part1: Technical requirements(draft)" and "Virtual reality games production technical requirements(draft)".
