The classification VR of virtual reality system involves many subjects, wide application fields and complex system types, which is determined by its research objects, research objectives and application requirements. From different perspectives, VR system can be classified differently.
Classification according to the perspective of immersive experience
Immersive experience can be divided into non interactive experience, human virtual environment interactive experience and group virtual environment interactive experience. This perspective emphasizes the interaction experience between users and devices. In contrast, users in non interactive experience are more passive, and the content they experience is planned in advance. Even if users are allowed to guide the scheduling of scene data to a certain extent, there is still no substantive interaction behavior, such as scene roaming, and users have almost nothing to do in the whole process; while in human virtual environment, interactive experience In the system, users can interact with the virtual environment by using devices such as data gloves, digital scalpels, etc., such as driving a fighter simulator, etc. at this time, users can perceive the changes of the virtual environment, and then generate various feelings that may be generated in the corresponding real world.
If the system is networked and multi-machine, and multiple users share a set of virtual environment, the group virtual environment interactive experience system, such as large-scale network interactive games, will be obtained. At this time, the VR system is not very different from the real world.
Classification according to system function
The system functions are divided into planning and design, display and entertainment, training and drilling. The planning and design system can be used for the experimental verification of new facilities, greatly shorten the research and development time, reduce the design cost, improve the design efficiency, and can be used in urban drainage, community planning and other fields, such as VR analog water supply and drainage system, which can greatly reduce the cost originally required for experimental verification; the display and entertainment system is suitable for providing users with realistic viewing experience, such as digital museum , large-scale 3D interactive games, film and television production, etc., such as VR technology has been used by Disney as early as the 1970s to shoot special effects films; training and exercise systems can be applied to various dangerous environments and some areas where it is difficult to obtain operating objects or high operating costs, such as surgery training, space station maintenance training, etc
