This paper describes the design, evaluation, and lessons learned from a project involving implementation of an immersive virtual environment for children called NICE (Narrative-based, Immersive, Constructionist/Collaborative Environments). The goal was to construct testbed exploration reality as learning medium within context primary educational reform themes past three decades. With focus on informal education domains with social content, embraces constructivist approach learning,...
High speed bulk data transfer is an important part of many data-intensive scientific applications. This paper describes aggressive scheme, called Reliable Blast UDP (RBUDP), intended for extremely high bandwidth, dedicated- or Quality-of-Service-enabled networks, such as optically switched networks. also provides analytical model to predict RBUDP's performance and compares the results our against implementation RBUDP. Our show that RBUDP performs efficiently over dedicated networks able...
Hybrid Reality Environments represent a new kind of visualization spaces that blur the line between virtual environments and high resolution tiled display walls. This paper outlines design implementation CAVE2<sup>TM</sup> Environment. CAVE2 is world's first near-seamless flat-panel-based, surround-screen immersive system. Unique to it will enable users simultaneously view both 2D 3D information, providing more flexibility for mixed media applications. cylindrical system 24 feet in diameter...
Current web-based collaboration systems, such as Google Hangouts, WebEx, and Skype, primarily enable single users to work with remote collaborators through video conferencing desktop mirroring. The original SAGE software, developed in 2004 adopted at over one hundred international sites, was
This paper describes the NICE project, an immersive learning environment for children implemented in CAVE and related multi-user virtual reality (VR) technologies. The project provides engaging setting where construct cultivate simple ecosystems, collaborate via networks with other remotely-located children, create stories from their interactions real world.
The authors present the experiences at Electronic Visualization Laboratory (EVL) in introducing computational scientists to use of virtual reality as a research tool. They describe environment, CAVE. then several applications currently being developed EVL using CAVE and conclude with discussion on possible paths follow making an effective tool for visualization.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
This architecture/infrastructure of parallel optical networks couples data exploration, visualization, and collaboration technologies through IP at multi-gigabit speeds.
Abstract The CAVE, a walk-in virtual reality environment typically consisting of 4–6 3 m-by-3 m sides room made rear-projected screens, was first conceived and built in 1991. In the nearly two decades since its conception, supporting technology has improved so that current CAVEs are much brighter, at higher resolution, have dramatically graphics performance. However, rear-projection-based must be housed 10 m-by-10 (allowing space behind screen walls for projectors), which limits their...
Constructing integrative visualizations that simultaneously cater to a variety of data types is challenging. Hybrid-reality environments blur the line between virtual and tiled display walls. They incorporate high-resolution, stereoscopic displays, which can be used juxtapose large, heterogeneous datasets while providing range naturalistic interaction schemes. thus empower designers construct more effectively mash up 2D, 3D, temporal, multivariate datasets.
Abstract Social network analysis is the study of patterns interaction between social entities. The field attracting increasing attention from diverse disciplines including sociology, epidemiology, and behavioral ecology. An important sociological phenomenon that draws analysts emergence communities, which tend to form, evolve, dissolve gradually over a period time. Understanding this evolution crucial sociologists domain scientists, often leads better appreciation system under study....
This position paper on Indigenous Protocol (IP) and Artificial Intelligence (AI) is a starting place for those who want to design create AI from an ethical that centers concerns. Each community will have its own particular approach the questions we raise in what follows. What written here not substitute establishing maintaining relationships of reciprocal care support with specific communities. Rather, this document offers range ideas take into consideration when entering conversations which...
The Scalable Adaptive Graphics Environment (SAGE) is specialized middleware for enabling data, high-definition video and extremely high-resolution graphics to be streamed in real-time from remotely distributed rendering storage clusters scalable display walls over ultra-high-speed networks. In this paper, we present the SAGE architecture, focusing on its dynamic streaming capability. framework, multiple visualization applications can large tiled displays viewed at same time. application...
A solid-state dynamic parallax barrier autostereoscopic display mitigates some of the restrictions present in static systems, such as fixed view-distance range, slow response to head movements, and stereo operating mode. By dynamically varying parameters real time, viewers may move closer faster laterally than with a system, can switch between 3D 2D modes by disabling on per-pixel basis. Moreover, Dynallax output four independent eye channels when two are present, both head-tracked receive...
Large high-resolution displays are becoming increasingly common in research settings, providing data scientists with visual interfaces for the analysis of large datasets. Numerous studies have demonstrated unique perceptual and cognitive benefits afforded by these analytics information visualization tasks. However, effects on knowledge discovery exploratory still poorly understood. We present results a small-scale study to better understand how display size resolution affect insight....
We present an approach to applying virtual reality in architectural design and collaborative visualization which emphasizes the use of multiple perspectives. These perspectives, including mental models as well visual viewpoints, allow be applied earlier, more creative, phases process, rather than just a walkthrough final design. CALVIN, prototype interface implements these ideas, has been created using CAVE theatre.
The paper describes a system, Imsovision, for visualizing object-oriented software in virtual reality Environment. A visualization language (COOL) is defined that maps C++ source code to visual representation. Our aim develop with few metaphors and constructs, but the ability represent variety of elements no ambiguity or loss meaning. In addition, has maximally use potential used media. design OO system its attributes are represented visualization. Class information, relationships between...

The development of applications and tools for high-performance "computational grids" is complicated by the heterogeneity frequently dynamic behavior underlying resources; complexity themselves, which often combine aspects supercomputing distributed computing; need to achieve high levels performance. Globus toolkit has been developed with goal simplifying this application task, providing implementations various core services deemed essential computing. In paper, we describe two large toolkit:...
