The Design Of Mobile Virtual Tourism Service Model Based On DOA And Study Of Virtual Roaming Technology

With the increasing pressure of life, tourism has become an important way toreduce stress, relaxation and entertainment, but some reasons such as the pace of life,the health of the financial and other constraints, more and more people choose totravel by new way.Virtual tours can provide people with convenient, fast and inexpensive way totravel,people can not only visit attractions goalat any time and place to change thementality and acquire knowledgewith the shortest time, but also for many of the mostpopular season tour place to share the pressure, so that the scenic environment,sanitation, convenience services and security problems can be eased and improved.On the other hand, touristscould feel the virtual scene by realistic scenery, stay awayfrom the crowded atmosphere.At the same time,our habits in Internet terminal is as well as changes in travelpatterns. In recent years, the access of internet has turned from the traditional PC sidegradually transferred to portable mobile terminal. As widely use of intelligentdevicesuch as mobile terminals smartphones, tablet PCs and so on, people’s lifestyleswhich including the field of tourismare changing,Although the virtual tour and the rapid development of mobile terminals arecurrently sunrise industry,domestic mobile virtual tour service platformhave a lot ofunsatisfactory place, just as thevirtual scene which presented in the overallthree-dimensional effect, aspects of virtual roaming settings, universal service ormanagement and so on.For the above analysis, the mobile virtual tour service model and designproposed is significant. This paper proposes a DOA architecture[1]under the mobilevirtual tour service model, the service model is different from traditional virtual tourof the scene shows a simple, nor stick to provide a single attractions showcaseservices, but relying on a generalized virtual tour definition emphasizes virtual Tour "immersion ", combining industry services, service model management model linkagedevelopment. By registering DOA architecture data management system, informationgathering-service aggregation functions to provide a theoretical basis for mobilevirtual network environment based on travel patterns, but also the theoretical framework of DOA in the mobile virtual tourism industry can be verified.In DOA architecture platform mobile virtual tours, virtual roaming module is oneof the most important part. Realistic virtual scene models, route setting, interaction,interface friendliness have a direct impact on the user experience of the serviceplatform to use. Traditional virtual scene shows a single-view or multi-showpanorama mode. This article will introduce the real terrain3D game engine, the use of3D game engine provides abundant component of scenes to achieve and research.The main work includes:(1) Research on mobile virtual travel industryVirtual tour virtual reality technology to expand in the field of tourism, tourismis as smart mobile virtual terminal equipment development and the gradual rise of thevirtual tour mode. This paper explores the definition, origin mobile virtual tourtechnology, the virtual scene the main technical structure, the current lack ofdevelopment of domestic industry and the prospect of future industry trends.(2) The function architecture analysis of DOADOA is a data-oriented architecture, it is in a way the metadata registries to solvethe problem of massive data due to network the number of users currently, the amountof resources caused by growth. DOA architecture combined with mobile virtualtourism industry can solve mobile virtual store multiple data types generated in thetourism industry, different characteristics of the data, queries, call other operations.(3) Research on the implementation technology of virtual roamingDue to the high threshold of the underlying graphics programming, this paperintroduces3D game engine for the virtual scene, not only to reduce developmenteffort, reduce development time, but also to simplify the export and post-projectoptimization complexity.(4) Completed the experimental area to build a virtual roaming scenariosComparison of existing popular mobile end3D virtual engine and itscomponents, the choice of ENVI+3ds Max+Unity3D software for technicalsupport to the main entrance of Chengdu University of Technology to create a virtualroaming platform for the test area, the scene of them roaming technology and relatedtechnologies to achieve research. Explore thedisplay and loading mode based on theWorld Wind tile layering technology for the virtual scene.The innovation points and achievements are summarized as follows:(1)Proposed a mobile virtual tours mode based on DOAThe mode in the form of three-dimensional virtual Earth, writer takes into account the status of the multi users and inadequate service chain. DOA schemainformation to client aggregation service aggregation functions and so on, based onthe network environment, multi-source, heterogeneous mass tourism data for effectivemobile virtual portfolio and management.(2) According to the proposed service model designed to move a virtual tourservice platform model DOA under an appropriate frameworkBased on data registry function mobile virtual tour service model to construct thecorresponding service platform, and the overall framework of the service platform,the basis of open source technology, mobile terminal modules, the deployment of theservice side, moving to build a virtual tour of the markup language and under theDOA framework six areas described.(Due to the country management mode,different policies and other factors, we only studied for ordinary tourists client)(3) Design of a mobile virtual tour Markup Language/MVTMLMobile Virtual tour Markup Language/MVTML (Mobile Virtual TourismMarkup Language) is a super Geography Markup Language/HGML expand in thefield of tourism, both of which provide exchange specification for mobilecollaborative virtual tour platform, enabling data to be stored in a unified format,express transmission. In this paper, according to HGML concept, designed to movevirtual tour Markup Language/MVTML, its concept, features, specifications,composition and analytical methods are described in turn. By controlling the virtualscene MVTML loading, service providers, state and basic geographic elements thatmake mobile virtual travel industry data can be unified management.
