However, the computational processes that underlie these capabilities in the human brain are still not fully understood. A powerful tool to study the representation and transformation of sensory information in the human brain are change-related paradigms. This text reviews three recent examples from our lab that employed change-related paradigms with different brain imaging modalities to characterize the representation of sounds in the human brain. Specifically, a first experiment used functional magnetic resonance imaging and signal response suppression after stimulus repetition to characterize the representation of natural sounds. A second magnetoencephalo-graphic experiment, used a two-tone paradigm to describe the time-course of adaptation to natural sounds. In a third experiment, we employed a spatial mismatch negativity oddball paradigm during electroencephalography to test for head-related versus allocentric representation of sound sources in the human brain.","PeriodicalId":103128,"journal":{"name":"Proceedings of the 3rd International Universal Communication Symposium","volume":"15 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":"130811820","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}

To enhance integral 3D image quality, Extremely High-Resolution (EHR) imaging technology would be essential. Now, projection display systems are practical for EHR images and have some advantages for 3D imaging. We theoretically and experimentally analyzed the effects of distorted elemental images on a reconstructed image. We study an image processing method for a compensation of distorted elemental images in projection type 3D imaging systems. The experimental results show the effectiveness in eliminating distortion of reconstructed 3D images and improving the limitation of the viewing zone.","PeriodicalId":103128,"journal":{"name":"Proceedings of the 3rd International Universal Communication Symposium","volume":"9 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":"125849799","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}

Simultaneously, human computer interactions have become more conversational in style, and more challenging in that they require various human conversational strategies, such as giving feedback and managing turn-taking. In this paper, we focus on eye-gaze in order to investigate turn taking signals and conversation monitoring in naturally occurring dialogues. We seek to build models that deal with the important aspects of which interlocutor the speaker is talking to, and what kind of turn taking signals the partners elicit, and we report the first results of our eye-tracking experiments.","PeriodicalId":103128,"journal":{"name":"Proceedings of the 3rd International Universal Communication Symposium","volume":"28 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":"122141762","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}

Our algorithm extracts human silhouette and reconstructs human shape via volume intersection from multi view point images. The method presented in this paper is based on energy minimization via graph cuts, and its main features are: 1) to reduce the background subtraction errors caused by background clutter, 2) to have robustness for influences of shadows, 3) to segment the foreground region even if moving objects other than human. The precise human shape reconstructed by the method improves the accuracy of human pose estimation. Especially, 3) leads to enhance the range of application of the voxel-based human pose estimation. We demonstrate the effectiveness of our approach in terms of both quantitative and qualitative performance where strong shadows appear and moving objects are present in intelligent environment.","PeriodicalId":103128,"journal":{"name":"Proceedings of the 3rd International Universal Communication Symposium","volume":"67 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":"131303789","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}

Sensors have critical dual roles in this process: (1) analyzing existing social relations, and (2) providing resources for establishing new relations. Several examples are discussed in relation to the latter role of sensors in shaping social landscapes, suggesting the possibility to create various representations that could support novel communication and collaboration practices.","PeriodicalId":103128,"journal":{"name":"Proceedings of the 3rd International Universal Communication Symposium","volume":"143 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":"132937813","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}
