Distributed Virtual Reality (DVR) is a combination of network and virtual reality technology, it could facilitate to construct a uniformly shared Distributed Virtual Environment (DVE) by using network to connect geographically distributed multiplayers. This paper concentrates on the theoretical research and practical development about Multiplayer Virtual Intelligent System (MVIS), and the main contribution could be summarized as two points. (1) Based on the DVR technology, this paper presented some theoretical research on MVIS, including the classification of virtual entities, communication pattern of entities, and the behavioral consistency research. Furthermore, a Multiplayer Earliest Deadline First (MEDF) program was proposed in order to guarantee the consistency of entities. (2) A prototype algorithm experiment system, called Multiplayer Graph-algorithm Intelligent System (MGIS), was designed. MGIS not onlyefficiently solves many problems in traditional computer algorithm teaching, such as high-abstraction, difficulty to understand, and lack of interaction mechanism; but also extends the application of DVR to cultural tourism, because MGIS is developed on the 3D scene of Lushan Mountain, which is one of the notable tourist attractions in China, and was included in the UNESCO World Heritage list in 1996. What i’s more, MGIS illustrates the ability of expression, applicability and generality of the theoretical research about MVIS.

This paper explores the tourism trends emerging in post COVID- world. This pandemic was conscientious for an abrupt transformation in the way world travelled. This impulsive impediment in the tourism and hospitality industry was not only unconstructive to the growth of the industry but the imminent influences on future tourism are also looking dim and muted. Virtual Reality has emerged as a new innovative approach to attract viewers though providing them a virtual experience of tourism a tour destination with enhanced technological version. Virtual reality is the new normal in the digital world. People are slowly gaining access to digital tourism experiences through Virtual Reality tourism concept. The increase in virtual reality tourism trend is most welcome thing globally. This trend capitalizes on the use of technology to make viewers experience a touring destination. It includes Virtual Reality tours through which a tourist or viewer can experience a tourist destination, hotel interiors, restaurant interiors, outdoor tourist attractions, shopping sites, archaeological inputs, museums, etc sitting in home. This viewer is made to experience complete visit of the destination through VR head gears and comply with his aspirations of touring. Without being physically present on the tourist site a viewer can become a tourist and see all sites as naturally as a tourister. But this usage of technology driven virtual reality tools are challenged by several factors.

Dead reckoning algorithms are employed in distributed virtual reality systems (DVR systems) for predicting objects states at any given moment of time that makes it possible to minimize bandwidth requirements while maintaining required data consistency. However, existing implementations often do not take into account information on the object motion dynamics and, in general, apply static prediction models. In this paper a novel motion-aware adaptive dead reckoning algorithm is introduced based on dynamical prediction model selection depending on the object motion pattern. The results show that considerable reduction in update messages can be achieved without sacrificing prediction accuracy. In addition, it becomes possible to dynamically adjust the size of update messages according to the motion pattern and, thus, provide more flexible use of network bandwidth.
