Improved chat tools are available to avatar agents in virtual space (e.g., Second Life) thanks to the fast-evolving 3D internet. The most common plain text chat is easy to use, but it is hard to understand who talks to whom. Advanced chat with 2D word balloons in 3D virtual space is difficult or unfamiliar, since it does not consider real world constraints. We propose a human-cognition based chat system for virtual avatars using geometric information. In our chat framework, if an agent (avatar) wants to talk with other people, then that agent should approach within an \"audible distance\" to read the text, as would be required in the real world to participate in a conversation. Additionally we propose a new model to manage the virtual chat social network over our cognition-based chatting system. Our experiment showed that the number of chat agents is saturated regardless of the number of chat agents, as occurs in real-world chat. Thus, the social-graph for chat agents is always of a manageable size in our cognition-based chat system.","PeriodicalId":182702,"journal":{"name":"Proceedings of The 7th ACM SIGGRAPH International Conference on Virtual-Reality Continuum and Its Applications in Industry","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124885792","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}

Skin detection has been widely used in various applications, such as face and hand tracking, people detection in the video databases. In this paper, we propose and develop an effective hand tracking method based on a simple color classification. This method includes two major procedures: training and tracking. In the training procedure, the user specifies a region on a hand to obtain the training data. Based on the skin-color distribution, the training data will be classified into several color clusters using randomized list data structure. In the hand tracking procedure, the hand will be segmented in real-time from the background using the randomized lists that have been trained in the training procedure. The proposed method has two advantages: (1) It is fast because the image segmentation algorithm is automatically performed on a small region surrounding the hand; and (2) It is robust under different lighting conditions because the lighting factor is not employed in our effective color classification. Several experiments have been conducted to validate the performance of the proposed method. This proposed method has good potential in many real applications, such as virtual reality or augmented reality systems.","PeriodicalId":182702,"journal":{"name":"Proceedings of The 7th ACM SIGGRAPH International Conference on Virtual-Reality Continuum and Its Applications in Industry","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124057134","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 particular, by dynamically applying different slice functions, any surface-closed geometric model can be voxelized into a solid volumetric representation with any kind of interior materials, such as rainbow, marble, wood, translucent jade, etc. In this paper, the design of the dynamic slice function, the principle and algorithm of solid slice creation, the algorithm of real-time solid voxelization, and GPU-based acceleration techniques will be discussed in detail. The algorithms introduced in this paper are easy to implement and convenient to integrate into many applications, such as volume modeling, collision detection, medical simulation, volume animation, volume deformation, 3D printing, and computer art. The experimental results and data analysis for the complex objects demonstrate the effectiveness, flexibility, and diversity of this approach.","PeriodicalId":182702,"journal":{"name":"Proceedings of The 7th ACM SIGGRAPH International Conference on Virtual-Reality Continuum and Its Applications in Industry","volume":"708 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122989125","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}

Numerous researchers concentrate to augment visual acuity in order to get sensible visualization and animation. In addition, acoustic has also became other aspects to enhance immersiveness of virtual reality game. Recently, there is an issue involving haptic as part of stimulating interactivity between virtual characters and players in order to obtain more attention from players. This paper presents the feasibility of how human haptic emotion being applied in virtual reality game. The idea is that through a haptic device the human emotion is sent to the game engine in order to gain more interactivity and immersiveness. The role of the device is to act as a bridge to deliver emotion sense from virtual character interaction into players from the sense of touch side. We classify each emotion into several different magnitude frequencies that are generated from the haptic devices. The intention of the classification is to tell players about the virtual character emotion during the playing period. This approach will be of great benefit in making virtual reality game more lively and impressive.","PeriodicalId":182702,"journal":{"name":"Proceedings of The 7th ACM SIGGRAPH International Conference on Virtual-Reality Continuum and Its Applications in Industry","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125024626","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}

With such a device, it is possible to continuously record a portion of the image entering one or both eyes. However, when using such a device, storage becomes one problem. Fortunately, this may be addressed both by efficient video coding, as well as the fact that information storage is becoming increasing large, and very inexpensive. A possibly greater problem is that given such a large and ever growing image and video collection, retrieval of images and videos becomes a demanding task. In addition, with growing image and video libraries, detection of modified copies increases in importance. In this paper, we present a framework for retrieving images/videos with an Eyetap device, that had also been captured by Eyetap devices, or by other means. We employ the ordinal-based method to tackle image and video indexing and retrieval with the enhanced similarity measure. Because our Eyetap video collection is still quite limited, we instead tested our system on 50 videos obtained from TRECVID 2006. From this experimental result, it is demonstrated that our system is efficient and robust, and thus appropriate for the Eyetap applications we have specified.","PeriodicalId":182702,"journal":{"name":"Proceedings of The 7th ACM SIGGRAPH International Conference on Virtual-Reality Continuum and Its Applications in Industry","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127505691","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}
