The UCSB Allosphere is a novel large-scale instrument for immersive visualization and simulation, which in its full realization will be one of the world's largest immersive environments. The three-story high cubical space comprises an anechoic chamber with a spherical display screen, ten meters in diameter, surrounding from one to thirty users standing on a bridge structure. The Allosphere is differentiated from conventional virtual reality environments by its size and focus on collaborative experiences, its seamless surround-view capabilities and its focus on multiple sensory modalities and interaction. The Allosphere is being equipped with high-resolution active stereo projectors, a complete 3D sound system with hundreds of speakers, and interaction technology. In this paper we will give an overview of the purpose of the instrument as well as the systems that are being put into place in order to equip it. We also review the first results and experiences in developing and using the Allosphere in several prototype projects.","PeriodicalId":340593,"journal":{"name":"International Conference on E-Health Networking Digital Ecosystems and Technologies","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124591219","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 driver for the change is an explosion in resolution brought about by the availability of 4K format displays. The affects include a shift from a longstanding one-to-one relationship between a source and a display, to a new paradigm where the display acts as a container for any source or many sources windowed into it. This shift challenges many long held integrations and display design standards and must be considered by anyone who is implementing large-scale displays for visualization, VR, command and control and special venue applications.","PeriodicalId":340593,"journal":{"name":"International Conference on E-Health Networking Digital Ecosystems and Technologies","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126575732","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}

Small- and medium-scale displays have received by far the most attention from researchers, perhaps due to their smaller size, lower cost and easy accessibility. Large-scale immersive displays present unique technical challenges largely met by niche manufacturers offering proprietary solutions. The rapidly growing number of largescale displays in planetariums, science centers and universities worldwide (275 theaters to date), coupled with recent trends towards more open, extensible systems and mature software tools, offer greater accessibility to these environments for research, interactive science/art application development, and visualization of complex databases for both student and public audiences. An industry-wide survey of leading-edge largescale immersive displays and manufacturers is provided with the goal of fostering industry/academic collaborations. Research needs include advancements in immersive display design, real-time spherical rendering, real-time group interactive technologies and applications, and methods for aggregating and navigating extremely large scientific databases with imbedded physical/astrophysical simulations.","PeriodicalId":340593,"journal":{"name":"International Conference on E-Health Networking Digital Ecosystems and Technologies","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114538963","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 gallery and its associated display technologies, cumulatively referred to as Victory Media Network®, incorporate a total of eleven large-scale outdoor LED video screens as well as LCD screens encased in kiosks distributed throughout the district to display video artwork from around the world. A unique track system engineered specifically for the project allows eight of the LED screens to move horizontally along the entire length of a major public plaza. This motion system affords myriad motion and configuration possibilities, synchronizable with artists' video designs to create complex and sophisticated spatial interactions. Additional visual and audio technologies support these fundamental capabilities to provide a deeply immersive public art environment.","PeriodicalId":340593,"journal":{"name":"International Conference on E-Health Networking Digital Ecosystems and Technologies","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121554385","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}

As the viewing angle increases, not only the luminance but also the color saturation decreases so that the image quality is compromised. In this paper, we characterize the viewing angle-dependent color shift of an LCD and propose a compensation method of adjusting the backlights and panel transmittance simultaneously. By increasing the panel transmittance, the color shift and luminance attenuation can be minimized. By increasing or decreasing the backlight intensity, the original luminance can be preserved or the power consumption can be reduced. The proposed method uses a video camera to capture the user's location for calculating the viewing angle. We have also implemented an emulator for reproducing the viewing angle-dependent visual effects.","PeriodicalId":340593,"journal":{"name":"International Conference on E-Health Networking Digital Ecosystems and Technologies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130844380","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 broadly refer to these displays as Ultra displays to distinguish them from displays designed for traditional video standards and formats such as High-Definition television. Although ultra displays afford exciting new capabilities, several new challenges must be addressed. In particular, current approaches to rendering, managing and distributing content will have to. We are in the process of exploring these issues as part of an effort to build and deploy a number of ultra displays with vastly different uses. Here we describe the different display prototypes and the challenges that they illuminate for the visualization, computer graphics, and human-computer interaction communities.","PeriodicalId":340593,"journal":{"name":"International Conference on E-Health Networking Digital Ecosystems and Technologies","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116950554","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}

Today, projectors are commodity products, making such displays are affordable, but several challenges must be overcome in order to make this technology available to everyday users. We present several advances in the area of multiprojector displays. These employ projectors with enhanced capabilities, methodologies for efficiently and inexpensively calibrating and maintaining displays composed of these units, and the ability to handle imperfect and uncalibrated devices when performing geometric and photometric registration of imagery across multiple projectors. These are the first steps in realizing the goal of truly ubiquitous pixels, where users can be completely oblivious to the type and number of devices providing the display.","PeriodicalId":340593,"journal":{"name":"International Conference on E-Health Networking Digital Ecosystems and Technologies","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130670153","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}
