The educational virtual environment is presented as a shared informational agent-based space from both modeling (structure and evolution point of views) and technical (implementation) perspectives. The cooperation within the environment is preserved by interfering with virtual actors. Current implementations are based on a client-server architecture. VEHA API is used for environment description, VRML, C++, and Java are used as modeling and programming languages, and AReVi as graphical rendering and interaction API. Supplementary ARToolkit is used for hand-made marker-based interaction","PeriodicalId":228139,"journal":{"name":"2006 International Conference on Cyberworlds","volume":"14 4 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":"123540671","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}

Aiming at the problem that semantic information is represented insufficiently when MRs are searched in MG, we propose an ontology-based MR discovery architecture which is based on semantic Web technology. Then from the point of view based on semantics and QoS (quality of service), the main framework of resource matchmaking is constructed, in which three processes are included: task modeling, resource modeling, semantic modeling and resource matchmaking. On the basis of resource representation model and manufacturing features-oriented task representation model, combining with the research results of semantic Web, some pivotal concepts are defined about the matchmaking resources. Finally, by means of a functional semantic extending method based on the ontology and QoS, the MR matchmaking algorithm is constructed","PeriodicalId":228139,"journal":{"name":"2006 International Conference on Cyberworlds","volume":"38 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":"115864015","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}

Previous work identified how poor understanding of floating point related issues lead to performance, architectural and accuracy problems.

On the other hand, different surroundings characterize different interactions, and may change the shapes and motions of the fluids in different ways. Therefore, it is of importance in physically-based simulation of fluids to build physically correct models to represent the varying interactions between fluids and the environments. In this paper, we make a simple summation on the interactions, and in particular focus on those most interesting to us, and model them with various physical solutions. In some of the methods, advantage is taken with the graphics processing unit (GPU) to achieve real-time computation for medial-scale simulation","PeriodicalId":228139,"journal":{"name":"2006 International Conference on Cyberworlds","volume":"3 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":"131932031","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 present an approach, which extends this concept in three ways: (1) the provision of maximum control for the therapist over the exposure environment, (2) the inclusion of different media and mediation elements in the virtuality continuum in mixed reality, and (3) support for co-located and remote collaboration between therapist and client. This paper gives a brief overview of related work in the field, describes our conceptual approach and a first implementation, and highlights initial findings and issues.

This paper introduces a novel method of integrating a live video object that is taken by multiple fixed cameras in a remote natural environment into a MR space. Using the captured live video frames, the view of the remote object corresponding to the user's current viewpoint in the MR space is generated in realtime based on the proposed fast view morphing algorithm, which ensures a natural image transition without reconstructing the 3D model of the object. During the user's free navigation in the MR space, the real-time generated view of the object is presented in that space, which results in a convincing impression that the remote object exists in the local realistic 3D MR space. Experimental results in both a desktop MR system and a CAVE-like MR system have demonstrated the validity of the proposed approach","PeriodicalId":228139,"journal":{"name":"2006 International Conference on Cyberworlds","volume":"40 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":"125908182","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}
