Research And Application Of Virtual Reality Interactive System Based On Perception Devices

Virtual reality integrated multidisciplinary technology,combined with related industries and fields,changed the way of human-computer interaction and opened up a whole new field of user experience.In recent years,with the rapid advancement of computer technology and hardware conditions,interactive technology has been rapidly developed.The existing virtual reality interaction system is too single to provide use in multiple environments;the original system requires a large number of sensor devices and high cost;the traditional perception technology is limited,and human-computer interaction cannot be realized more naturally.Through the analysis of the function and performance requirements of virtual reality system,in this paper,a virtual reality interaction system based on sensing device is designed and developed.The system can not only be used in multiple scenarios to improve the interactive experience,but also reduce system application costs,help advance the related industries,and realize the application and promotion of virtual reality technology.The main contents and results of the study are as follows:(1)Through the research of the existing system and the actual demand analysis,this paper divides the virtual reality system into two application modes.In order to ensure the reliability and authenticity of the virtual reality system,an immersive virtual reality system is selected to be implemented on the PC side.The use of mobile smart devices to implement enhanced virtual reality systems increases the convenience and diversity of traditional virtual reality systems.The two virtual reality modes complement each other,provide different use environments,and establish a complete virtual reality interaction system.(2)For enhanced virtual reality interaction systems and mobile smart devices,this paper proposes a frame marker tracking registration technology.The use of the Frame Marker has the advantages of small workload,convenient size adjustment and portability,and it integrates the content of the identification card and the real scene.Using 3ds Max to complete modeling and animation of virtual scenes.On the Vuforia Engine and Unity 3D platform,enhanced virtual reality features are implemented using frame markers and 3D models.(3)For the immersive virtual reality interactive system,Leap Motion is used to implement the interactive control of the immersive virtual reality system,which completely liberates people's hands and improves the user experience and realism.By analyzing the principle of Leap Motion and gesture acquisition,Leap Motion and HTC Vive combine to present an immersive virtual reality interaction system.Based on the above research on virtual reality and human-computer interaction technology,the design of the virtual reality interaction system is completed.Through theenhanced and immersive two different application modes,the user can not only feel the reality brought by the virtual reality technology,but also help the user not to be limited by time and place and improve the cognitive efficiency.This article applies the system to the education and training of railway-related personnel,making it easier for railway practitioners to quickly grasp new railway technologies and equipment.
