However, the essence of P2P is missed by broad interpretations that do not make it a problem whether to use P2P technology. Incidentally, although marketing activity currently consists mainly of Web pages or mail, it is difficult to actively find latent customers from the company side, and it is not necessarily an effective marketing means for a small-scale company. Therefore, in this paper, we discuss the application of P2P technology to marketing. First, the essence of P2P is correctly extracted by focusing on the state of the information that changes within a P2P network, and effective fields in business are clarified. Next, by paying attention to characteristics of P2P that have not yet been adequately developed in business, we have recognized that P2P marketing is promising from now on. We devise five models for applying P2P networks to the marketing field (P2P marketing), and clarify P2P's marketing features through comparisons with existing Internet marketing. Consequently, we reveal features not currently held by Web pages or mail.","PeriodicalId":130458,"journal":{"name":"Proceedings. 2003 International Conference on Cyberworlds","volume":"267 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116539487","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}

A synchronous groupware system supports group members' collaborative activities at the same time. Due to the almost all of current synchronous collaborative systems have been implemented either using a centralized topology or a hybrid topology, the research presented in this paper has been devoted to investigation, design and implementation of a peer-to-peer (P2P) groupware system, called DSC, using a decentralized topology. As it does not use any server at all, peers in a group need to coordinately manage their group by themselves, and each peer has to fully handle the correct message passing by itself. The DSC system is implemented using the JXTA technology and platform that enable peers to find each other, form groups and exchange messages across firewalls and NATs. It currently offers three shared objects of Web browser, file viewer and drawing pad as well as a text chat tool. The synchronous controls of a shared space, the objects, telepointer and so on are also provided. Its evaluations with a practical test environment are given in detail.","PeriodicalId":130458,"journal":{"name":"Proceedings. 2003 International Conference on Cyberworlds","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131261789","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}

However, it is still hard and not intuitive to modify the overall shape of a model while preserving its details by manipulating its control points at lower resolution levels. A better control of deformations and a more intuitive interface should allow the user to control the deformation of a model by manipulating the model directly. This can be achieved by using variational modeling techniques. This paper presents a variational framework for multiresolution model design. The modeled shape is represented as a multiresolution B-spline curve or surface, which can be interactively deformed by direct user inputs. The focus of this paper is on handling multiresolution constraints and preserving surface details throughout the deformation process. To avoid smoothing out the details of the shape in variational modeling, we optimize the deformation energy alone instead of the total energy of the deformed shape. To accelerate the convergence of the iterative energy minimization process, a wavelet-based iterative method is used to compute the solution in a hierarchical fashion.","PeriodicalId":130458,"journal":{"name":"Proceedings. 2003 International Conference on Cyberworlds","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129583638","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}

Constructed heterogeneous collaborative VE consists of different VR display systems such as a virtual table and a projection wall. Since the virtual table provides a table-type workspace on a horizontal screen, it is efficient for interactive design of a building with a bird's-eye-view. However, it is not so efficient to view a designed building in the same proportions as that for a real building. On the other hand, as the projection wall is a vertical type VR environment having a large display, it enables simulation of the whole design process on a virtual table in frontal view. In addition, it also enables navigation around the building and in its surroundings. So we propose to use a projection wall as well as virtual table for constructing virtual environment so that design and simulation could be performed at the same time in each environment. Since the two VR systems are located close to one another, the user in the projection wall can participate in the design process that is performed in the virtual table indirectly through verbal communication. Guided 3D interaction techniques are also described for designing a building with ease in the 3D VR environment.","PeriodicalId":130458,"journal":{"name":"Proceedings. 2003 International Conference on Cyberworlds","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117188976","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}

This paper presents the virtual experiment (VE) environments for science education using virtual reality simulation. We developed the VE environments on the Web designed compatible to the learner levels through level analysis in the learning contents. The students can select the learning level in the exploring step of learning cycle model: regular, advanced and remedial courses according to the degree of their understanding or interest about the learning topic. The VE environments support students to learn scientific phenomena and concepts focusing on: the seismic wave, the Earth's crust balance, radiation balance, the movement of ocean, solar system and the control of telescope in the science field of middle school. The responses of learning on VE environments have demonstrated that the VE environments can be used as a useful methodology in science education for middle school students.","PeriodicalId":130458,"journal":{"name":"Proceedings. 2003 International Conference on Cyberworlds","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121254150","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}
