By registering entire scenes along every street and scenes at many locations, people can visually travel from street to street, and reach their destinations in cyber city. The issues we discuss here are how to map a large scale area to image domain in a small amount of data, how to cover visual information as complete as possible in the mapping, and how to effectively display the captured scenes for various activities in cyber city. Route Panoramas captured along streets and Panoramic Views captured at widely open sites are associated to city maps to provide a navigation function. This paper focuses on the properties of our extended images - route panorama, the archiving process applied to an urban area, and a real environment we developed to transmit and display scenes on the WWW and portable devices. The created cyber spaces of real cities have broad applications such as city tour, real estate, E-commerce, heritage preservation, urban planning and construction.","PeriodicalId":130458,"journal":{"name":"Proceedings. 2003 International Conference on Cyberworlds","volume":"28 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":"122309553","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}

Due to the distributed architecture of DVEs, it is generally not easy to evaluate the performance of DVEs. In this paper, we propose a consistency model based on a metric called time-space inconsistency. The model relates a human participant's perception to the characteristic parameters of a DVE. Based on the model, the performance of a DVE can be easily evaluated without the actual execution of the DVE application, which is especially useful in the designing stage of a DVE. A ping-pong game is developed to verify the proposed model. Experiment results show that the model is effective in evaluating the performance of the game.","PeriodicalId":130458,"journal":{"name":"Proceedings. 2003 International Conference on Cyberworlds","volume":"6 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":"124046350","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}

Specialized modelling tools, which exploit knowledge of the types of object being modelled by working in the application domain, can be used to create appealing virtual reconstructions quickly. At the same time, the structural information from the modeller gives valuable hints to the renderer to determine efficient interactive display strategies through the use of level-of-detail and culling techniques. Thus a modeller that knows the operator is creating houses can use this information to simplify the user interaction, guide the operator, and to create models that build in optimisations when attempting real-time rendering. In this paper we discuss the way in which polygonal and multi-resolution surface techniques can complement one another in the modelling of urban environments. We also draw more general conclusions which apply to other software systems that share the same objective.","PeriodicalId":130458,"journal":{"name":"Proceedings. 2003 International Conference on Cyberworlds","volume":"22 15 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":"124497291","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}

The emphasis of the project is to address (1) the sharing of cardiovascular clinical data; and (2) the system integration for CHD cardiovascular research. The system currently under development is mainly implemented on a PC Window platform with an intranet-centric design. An Apache HTTP server, a MySQL SQL server, Perl, and R Language, are employed for the system development independent to hardware platforms. The system offers easy information management and data sharing by multiple parties across Internet. Major datasets include lipoprotein phenotype/genotype and laser confocal images. A user-friendly interface is designed allowing users to deposit, retrieve, visualize and analyze the CHD information from different sites.","PeriodicalId":130458,"journal":{"name":"Proceedings. 2003 International Conference on Cyberworlds","volume":"28 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":"125077942","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}

An online survey was conducted to the players of one of famous Internet based games called 'Lineage'. 'Lineage' has become the biggest online game in the world accommodating over 6 million users worldwide, where people create his or her new identities and play various roles. 4,786 game players have participated in the survey, and their lifestyles were identified with their values and attitudes in the virtual world. Upon classification of their lifestyles, the behavioral tendencies and characteristic desires were compared by the lifestyles in virtual world. The study showed that game players have developed their own distinctive lifestyles, and the lifestyles were strong criterion on explaining the behavior patterns and their different desire to achieve in the world among them. The lifestyles were classified into three general categories: Single-Oriented Player, Community-Oriented Player, Off-real World Games. Each group displayed distinct differences in their values and game activities, as well as anti-social behavior tendencies. The differences were reflecting not only their personality but also their socio-economic status within the virtual world that is constructed through the game activities. This study hopes to serve as a model to understand how players from different real life backgrounds will behave to the various game features and how they adopt the virtual world for their new social identities.","PeriodicalId":130458,"journal":{"name":"Proceedings. 2003 International Conference on Cyberworlds","volume":"145 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":"116727479","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}

In second decision making module, we introduce Linguistic Rules-Tree (LR-Tree) which is the combination of fuzzy logics and decision tree but LR-Tree may not be the best generalization due to over-fitting. Consequently Neuro-Pruning method has been introduced for post pruning of LR-Tree. In Neuro-Pruning, instead of absolutely removing nodes, we employ a back-propagation neural network to give weights to nodes according to their significance. After data cleaning and decision making modules we hope that, our proposed approaches will be able to handle attributes with differing costs, improving computational efficiency, outperforms error-based pruning, handle uncertain and missing continuous time-series data.","PeriodicalId":130458,"journal":{"name":"Proceedings. 2003 International Conference on Cyberworlds","volume":"10 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":"116764010","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 algorithm predicts which neighbouring viewcell will be needed in the near future according to the current view position of the client and prefetches the pre-computed potential visible set (PVS) for that viewcell to the client-side cache. Our algorithm has a low memory requirement for the client-side cache. With the same cache size, our algorithm offers a much better performance than the simple neighbour prefetch method. We also provide a delta-transmission algorithm to optimize the prefetch transmission procedure by avoiding transmitting those geometries that are already in the client-side cache. A cache management and entry replacement strategy is also proposed to maintain the client-side cache.","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":"129243704","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 modeled each consumer's evaluation process by relationships among physical features of objects, each consumer's subjective interpretations and preferences. Thus, based on the models, our system can estimate users' subjective evaluations and preferences from physical features of objects to perform a suitable recommendation.

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}
