# The Influence of Immersive Virtual Reality Systems on Online Social Application
## 1 Introduction  
### Subject  
As a popular form of social communication in recent years, information exchange of social networking has no limitation in time and space due to the special nature of network service and database technology [1]. However, lack of advanced interaction technology brings some problems in expression of intent. At present, network social communication is limited to the form of text and pictures, which can only simulate forms of information transmission such as letters, bulletin boards, and so on. This leaves users with few options for expressing their intentions [2]. Traditional social software is too simple in its expression of single information in social networking, and the distortion rate is high in the process of channel transmission, which makes the receiver unable to understand the information correctly and accurately.  
For example, WeChat, a WIMP GUI-based social software, allows users to use nicknames and avatars as personal identifiers, and can communicate or share information with others via text, pictures, voice, and video, as shown in Figure 1. However, such social applications lack interaction with othersand expression of information via body language. This kind of expression is very different from the way people express themselves in the real world. This interaction design limits the user's intended expression and often requires a long period of training before the user can use the functions provided by these applications.  
Is it possible to design new social software that mimics the real world? The appearance of virtual reality technology gives us a feasible scheme.  
Virtual reality technology can be considered a kind of advanced UI technology, while the immersive virtual reality system is a more advanced and ideal virtual reality system that tries to fully mobilize the user's perception [3]. It provides a completely immersive experience, giving the operator the feeling of being in a real situation. Head-mounted display (HMD), data glove, and other devices are used to enclose the operator's vision, hearing, and other senses in a designed virtual space [4; 5]. The technical advantage of the virtual reality system lies in its use of changes of objects or environments in 3D scenes to output content to users. Traditional desktop UI can only map changes of data generated by information or interaction to two-dimensional representation through metaphor, and what is presented in front of users is changes of pictures or words [6]. Virtual reality technology can directly simulate various responses in real scenes. Using virtual reality in social applications can extend some new modes of operation [7].  
There is no doubt that virtual reality is a powerful, high-dimensional, option-rich UI development technology. However, to solve the interaction defects of traditional social applications, the most important thing is to propose a better interaction model.  
Development of user interface of human-computer interaction has gone through three periods. The first period, from the early 1950s to the early 1960s, was a user-free phase with punched-card input and line-printer output. The second period, from 1960 to the early 1980s, involved the use of mechanical or teletype typewriters for command entry, which continued into the age of personal microcomputers with command line shells (such as DOS and Unix). The third period, from the 1970s to the present, uses WIMP GUI. WIMP GUI based on Windows, ICONS, menus, and pointing devices has been dominant for more than four decades, thanks to its superior performance in handling common desktop tasks [6]. Professor [PERSON] of Brown University proposed the next generation of user interface specifications, post-WIMP, in 1997 [8; 9]. Such user interfaces do not rely on menus, Windows, or toolbars for metaphors, but instead use methods such as gestures and speech recognition to determine specifications and parameters of operations.
