Design And User Experience Of Virtual Tourism System Of Beijing Temple Of Heaven

The development of virtual reality technology has given birth to the rise of virtual tourism.Virtual tourism can make people stay at home and travel around the world,and bring tourists immersive experience.It provides an ideal solution for those who are not allowed to travel in the physical and economic aspects.It has a very broad application prospect,and also attracts a large number of scholars' research.However,the current research on the development process and user experience effect of virtual tourism products is relatively small,which fails to form a systematic theory.In this paper,the design and development process of desktop virtual tourism system and immersive virtual tourism system are introduced and practiced in detail,and the user experience effect of the two systems is deeply studied.Firstly,the concept,classification and equipment of virtual reality technology are summarized,and the basic principle of this research is discussed.Then through the research on the concept definition,application cases and product types of virtual tourism,this paper puts forward the development process of virtual tourism products,including demand analysis and design implementation.Demand analysis includes information collection and user research of scenic spots,which can determine the content of virtual tourism system.The design includes three steps: scene reappearance,interaction setting and test release.Secondly,taking the actual design and development of desktop virtual tourism system and immersion virtual tourism system in the temple of heaven scenic area as examples,the feasibility of the development process is verified.After demand analysis,the virtual tourism system of the temple of heaven selected part of the contents of the hall of praying for new year and Yuanqiu altar for performance.In the process of design and implementation,the desktop virtual tourism system uses Vray for 3dmax to generate 720 panoramic images from the three-dimensional model of scenic spots,and realizes interactive settings with the help of720 yun platform.Users can experience naked eyes or switch to VR glasses mode to experience with mobile phone box.Immersive virtual tourism system uses 3dmax to build three-dimensional models of scenic spots,which can be set interactively in Unity3 D.Users can use HTC vive devices to experience.After testing,the two systems are running stably and well.Then,in order to study the user experience effect of the two systems,this study constructs a user experience evaluation model suitable for virtual tourism,with indicators and weights of18% for interactive experience,20% for content experience,12% for aesthetic experience,20%for emotional experience and 30% for immersion experience.Next,the data of the above five dimensions are collected through the experiment,and the user experience effect and difference of the two systems are obtained through the analysis of the experimental data.A total of 24 subjects were recruited in this experiment,12 of whom experienced desktop virtual tourism system and 12 experienced immersive virtual tourism system.Data analysis shows that the two systems have advantages and disadvantages to each other.The desktop virtual tourism system is more flat,and the subjects' point of view in the virtual environment is fixed.Its immersion experience is generally inferior to the immersive virtual reality system which can roam freely.However,it has stronger operability,lower learning cost and networking characteristics,which can further enrich the subjects' experience.In the immersive virtual tourism system,the subjects tend to be more surprised and immersive.It can make the subjects have a stronger sense of being in the scene,and the subjects have a stronger desire to walk and explore in the virtual scene.They can view the objects in the virtual environment from close range and multiple angles according to their own ideas,which makes the subjects' experience more profound.Finally,based on the above research results,two optimization directions of virtual tourism system are proposed,hoping to provide guidance for future research.
