However, continuous emission of a scent creates problems of human adaptation to the lingering olfactory stimuli. During long movie scenes, viewers can not detect an emitted scent continuously. To overcome this problem we applied pulse ejection to repeatedly emit scent for short periods of time to ensure the olfactory stimuli do not remain in the air to cause adaptation. This study presents the decision procedure for the ejection interval Deltat required while considering the olfactory characteristics of subjects. The developed method provided the user with an olfactory experience over a long duration, avoiding adaptation.","PeriodicalId":110856,"journal":{"name":"17th International Conference on Artificial Reality and Telexistence (ICAT 2007)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121919263","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 computer graphics applications, multiple-camera-based object reconstruction is becoming popular for modeling 3D objects. However, geometrical and photo-metrical calibrations among multiple cameras still require high computational cost. We employ multiple observations of a spherical marker in a sequence for modeling illuminations. These data are also used for calibrating camera geometries based on a bundled adjustment method to minimize re-projection errors. The illumination condition is modeled as a set of luminance patterns on the virtual planes surrounding the target observation area. An illumination model at an arbitrary position in the scene can be constructed by interpolating the luminance behavior of surrounding planes. Experimental results show the effectiveness of our proposed method.","PeriodicalId":110856,"journal":{"name":"17th International Conference on Artificial Reality and Telexistence (ICAT 2007)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133157056","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 efficient partitioning arises from the need of high consistency maintenance among participating users' view, as virtual reality applications are characterized by the high degree of realism they aim to achieve. To the direction of partitioning algorithms, a lot of work has been done, which has been more intense due to the evolution of network technologies and the familiarization of users with virtual reality systems. This paper presents a partitioning approach, which is based on the degree of interaction of each virtual object and the behavior of the participating users, in terms of moving trends, which is usually directed by the actions they can perform on the surrounding objects. In particular, the partitioning takes place when the virtual world contains only objects, in the sense that no avatars are yet connected and objects' attributes are handled as indicators for avatars' future behavior in the system. This prediction of avatars' behavior based on objects' attributes defines the initial partitioning of the virtual space.","PeriodicalId":110856,"journal":{"name":"17th International Conference on Artificial Reality and Telexistence (ICAT 2007)","volume":"30 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114135776","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 proposes a room-sized immersive projection display system named CC room. In this system, the rounded corner of an ordinary room was used for the screen, and the projectors equipped with the fish-eye lenses were used to project wide angle images. By using this system, an immersive virtual environment that covers the user's view can be generated using one PC and one projector system. This system was connected to the JGN2 network and it was applied to the tele-immersive communication using video avatar. This paper describes the system construction of the CC room, the distortion correction method, the evaluation experiments and the tele-immersion applications.","PeriodicalId":110856,"journal":{"name":"17th International Conference on Artificial Reality and Telexistence (ICAT 2007)","volume":"455 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121805772","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 then executed both message loop procedures for Windows mouse event handling and those for multiple mouse event handling. We could display multiple mouse cursor images and utilize both mouse devices separately.

This work intends to contribute in assessing benefits of stereoscopic viewing for different virtual reality (VR) technologies. The investigation is performed under different conditions and it uses both synthetic and real images. The investigation concentrates on few aspects: comparative evaluation of VR facilities, the influence of selective visual attention on robot tele-drive, performance in collision avoidance and distance estimation. Results from a set of test trials run on 3 different VR facilities in 5 different configurations, emphasize some tendencies and represent a base for further investigations.","PeriodicalId":110856,"journal":{"name":"17th International Conference on Artificial Reality and Telexistence (ICAT 2007)","volume":"347 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116493419","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 this paper, we present a linear or nonlinear deformable model of soft tissue. In addition to the efficient meshing and basic finite element method, the high computation rate is achieved through two novel methods. Firstly, the major calculation work in the conjugate gradient solver for deformation is moved from the CPU to GPU in order to promote the calculation. Secondly, we apply the hybrid structures of deformable models, by fully calculating the volumetric deformation in the local operation part while only calculating the global deformation by medial representation method. Experiments have been given to show the feasibility and efficiency of the model.","PeriodicalId":110856,"journal":{"name":"17th International Conference on Artificial Reality and Telexistence (ICAT 2007)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122708623","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}
