The interactivity of a DVE is of crucial importance, as its success greatly depends on users' perceptions when interacting within the virtual world. In this paper, different from traditional application-centric approaches like dead reckoning, we propose a network-centric approach to enhance the interactivity of DVEs by directly reducing the network latencies in client-server communications. We consider a key problem with this approach, termed the server placement problem. Generally, this problem concerns how to place servers in the network to reduce client-server communication latencies. We then suggest several degree-based server placement approaches. Extensive simulation studies using realistic models have shown that appropriate server placement is very effective in enhancing the interactivity of large-scale DVEs","PeriodicalId":228139,"journal":{"name":"2006 International Conference on Cyberworlds","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126817693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Navigation within the Java 3D virtual environment includes the real camera motion control and the video output. The real object is chroma-keyed and embedded in a virtual setting. Future steps of the work include: 1) development of complementary 3D content and specific navigation tools for the decorative arts collections exhibits.

A typical scene comprises virtual entities that take decisions in real time in response of perceived environmental changes. The actions performed lead to the fulfillment of one or more goals specified by the scenarist. We have developed an open agent-oriented system. It provides a number of tools useful to create virtual scenes, including a rendering and a scene descriptor. Besides, it allows the addition of new services, like behavior controllers, 3D-object descriptors and virtual worlds. The design of a world not only involves specifying the environment graphical features, but also the rules that control the interaction between entities. This paper deals with the system architecture and the language provided to describe both a scene and a virtual world","PeriodicalId":228139,"journal":{"name":"2006 International Conference on Cyberworlds","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115226855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have already shown that numerical analysis can be applied to the dead reckoning data between frames using parametrics calculated from the data over the last several frames based on polynomial models. Based on the above polynomial models, we proposed the new dead reckoning method to extrapolate the attribute data which arrives at discrete time period. We showed that theoretical models which approximate the statistical error of dead reckoning data can be formulated based on parameters such as the update interval and changes in the data. Theoretical models showed that the average error of proposed method is less than that of current method. Finally, we evaluate the validity of the proposed method with the comparison of current method by conducting experiments with the pen motion of a series of letters written by human. We confirmed that the proposed method can decrease the extrapolation error in comparison with current method in average","PeriodicalId":228139,"journal":{"name":"2006 International Conference on Cyberworlds","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124486022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
