However, few studies measured vergence and accommodation simultaneously while viewing a real 3D scene and its 2D image on a traditional display. In this study we measured vergence and accommodation responses simultaneously while viewing a 3D real object located at various distances from the participant and its 2D image (photograph) including background scene presented on a display located at fixed distance. The result shows that vergence and accommodation varied with changing target distance while viewing the 3D real object, as expected. On the other hand changing target distance depicted in the photographic image while viewing the 2D display evoked no systematic change of vergence and accommodation. Some participants showed that noticeable accommodation lag and fixation disparity. In addition to that we observed considerable conflicts between vergence and accommodation in both 3D and 2D conditions, but no one reported perceived defocus and/or double vision. There were varieties of individual differences in the pattern of the conflicts.","PeriodicalId":103128,"journal":{"name":"Proceedings of the 3rd International Universal Communication Symposium","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128432885","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 feature is an essential component of communication technology. Generally communication technology pursues for exchanging and sharing of thoughts, feelings and ideas. 3-D displays are effective contact media to achieve these goals. The concept of accessible spatial dimension of a person is used to describe 3-D display in the aspect of communication technology. It is classified into three dimensions and each of dimensions represents the dimension of contact media. Several research results, related with 3-D display and communication technology are introduced based on the concept.","PeriodicalId":103128,"journal":{"name":"Proceedings of the 3rd International Universal Communication Symposium","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132127209","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 integral imaging system reproduces light beams similar of those produced by a real object. Therefore our displays have continuous motion parallax. The design, fabrication, and optical evaluation of the displays have been made. By using our proprietary software, the fast playback of the CG movie contents and real-time interaction are also realized with the aid of a graphics card. Realization of the safety 3D images to the human beings is very important. We have measured the effects on the visual function and evaluated the biological effects. We have found that our displays show better results than those to a conventional stereoscopic display. Our display architecture is suitable for flatbed configurations because it has a large margin for viewing distance and angle. Mixed reality of virtual 3D objects and real objects are also realized on a flatbed display. The new technology opens up new areas of application for 3D displays, including communications, arcade games, e-learning, simulations of buildings and landscapes, and even 3D menus in restaurants.","PeriodicalId":103128,"journal":{"name":"Proceedings of the 3rd International Universal Communication Symposium","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124926923","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}

Consequently, it becomes an emerging issue to manage exploding amount of Geoweb contents more efficiently than traditional approaches for mapping contents on a digital earth and/or a time line. In this paper, we propose a novel approach for managing Geoweb contents based on the idea of moving phenomena such as a typhoon and price escalation. Our moving phenomenon DBMS defines data types and predicates of moving phenomena, and the visual query interface, called Sticker, allows users to aggregate Geoweb contents with 3D view of the moving phenomena. Our framework works well for obtaining comprehensive knowledge about the situations or influences of real-world phenomena from the Geoweb contents.","PeriodicalId":103128,"journal":{"name":"Proceedings of the 3rd International Universal Communication Symposium","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127363853","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 subjects first rated the extent to which the aromas enhanced the reality of the visual images. CONTENTS of these visual images were different kinds of trees. Nine aromatic materials received high ratings. The subjects then rated the aromas using adjectives. The nine aromatic materials were classified into two clusters on the basis of the adjectives.

Since an HRTF is defined as an acoustic function of time and location of sound source, the spatio-temporal frequency characteristics of HRTFs can be visualized and analyzed by multi-dimensional Fourier transform in time and space. In our experiments, we investigate a basic property of the spatio-temporal frequency characteristic and the difference between HRTFs obtained by numerical analysis and actual measurements. The influences caused by pinnae for the spatio-temporal frequency characteristic are also examined. It is found that the spatio-temporal spectral components are mostly concentrated in specific frequency bands, and these components are different in each measurement condition.","PeriodicalId":103128,"journal":{"name":"Proceedings of the 3rd International Universal Communication Symposium","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116788198","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}
