    The National Science Foundation's Workshop on Human-Centered Systems: Information, Interactivity and Intelligence (Feb. 1997) underlined the need to incorporate people as an explicit design component. The resulting research recommendations will help define the agenda for one of five elements in a new high-performance computing initiative. This article summarizes preliminary research recommendation... View full abstract»

  • Virtual reality provides real therapy

    Publication Year: 1997, Page(s):16 - 20

    Virtual reality (VR) lets people act within and upon computer-generated environments, making it ideal for exposure therapy and some other forms of mental health treatment. In addition to representing stimuli with some degree of realism, a virtual environment (VE) lets users look at and interact with these things much as they would in the real world, using primarily their eyes and hands. This gives... View full abstract»

    Many interface devices for virtual reality provide full immersion inside the virtual environment. This is appropriate for numerous applications that emphasize navigating through a virtual space. However, a large class of problems exists for which navigation is not the critical issue. Rather, these applications demand a fine-granularity visualization and interaction with virtual objects and scenes.... View full abstract»

  • Visualizing resource allocation tasks

    Publication Year: 1997, Page(s):6 - 9
    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (176 KB)

    Allocating resources-whether labor or tools-is a ubiquitous task in factories, hospitals, airlines and communication network companies. It also exemplifies decision-making problems involving complex, changing criteria and presents unusual challenges to information systems from the modeling and problem-solving points of view. We present information visualization techniques to reallocate resources f... View full abstract»

    A workspace for information analysis must support two types of analysis: routine information reporting and exploratory analysis. We have been developing a workspace called Visage to address both types of analysis tasks. Our goal is for expert users to move easily between routine tasks and exploratory data analysis as situations demand. Furthermore, recognizing the inherent complexity of data analy...

  • Using MineSet for knowledge discovery

    Publication Year: 1997, Page(s):75 - 78
    Cited by:  Papers (9)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (252 KB)

    MineSet aids knowledge discovery and supports decision making based on relational data. It uses visualization and data mining to arrive at interesting results. Providing diverse visualization tools lets users choose the most appropriate method for a given problem. The client-server architecture performs most of the computationally intensive tasks on a server, while the processed results return to ... View full abstract»

  • Extending distortion viewing from 2D to 3D

    Addresses the visual exploration of 3D information layouts. Several visual exploration techniques have been proposed for 2D information layouts. Many of these try to take advantage of humans' natural visual pattern-recognition abilities to understand global relationships while simultaneously integrating this knowledge with local details. This desire for detail-in-context views (also called fisheye... View full abstract»

  • Two-handed volumetric document corpus management

    Publication Year: 1997, Page(s):60 - 62

    To find a document in the sea of information, you must embark on a search process, usually computer-aided. In the traditional information retrieval model, the final goal is to identify and collect a small number of documents to read in detail. In this case, a single query yielding a scalar indication of relevance usually suffices. In contrast, document corpus management seeks to understand what is... View full abstract»

    The Year 2000 software conversion effort dramatically illustrates how time consuming and costly maintaining large computer systems can become, especially when each system consists of millions of lines of source code. Understanding how a system's components interact is a key factor in implementing portfolio-wide changes, adding new features, and providing ongoing system maintenance. Any help that s...

    Increasingly, the World Wide Web is being used to help visualize complex relational information. We have developed a number of Web-based information visualization prototypes and applications by adapting several well-known information visualization ideas and techniques for use within Web environments. Before delving into specific examples, we offer some relevant background about the Web and our use... View full abstract»

    A tennis novice watching a match for the first time might be surprised that the crowd erupts with cheers when a player wins one point, then barely applauds when he wins the next. The crowd is not necessarily fickle; some points are genuinely more important than others because a tennis match is hierarchically structured. One match consists of several sets. One set consists of several games. One gam... View full abstract»

    A good 3D visual imagination is valuable for anyone working in 3D graphics. An excellent way to develop that imagination is to build models and hold them, turn them, and study them. The author begins with Platonic solids. He shows an unfolded shape, such as a tetrahedron made of four equilateral triangles, and includes small assembly flaps. He shows the unfolded diagrams or nets for these solids. ... View full abstract»

    Three-dimensional computer graphics can be extremely expressive. With the correct approach to a layout's visual design, people can quickly and easily comprehend large amounts of information. You can convey far more information in 3D than with 2D bar charts, or rows and columns of numbers. This article provides examples of information visualization applications in several industries, including the ... View full abstract»

    The paper discusses research on Z-GUI which builds on the principles of graphical user interfaces, adding 3D and new interaction modes to create a more powerful way to see data. Pushing graphics, space, and animation to an extreme, the GUI paradigm can reach an entirely different level of power with Z-GUI View full abstract»
