    In order to understand the behaviour of distributed program environments, we describe a three-dimensional visualization of communications. Most previous visualizations presented communications by means of the two dimensions of time and process, however, three dimensions are required to represent a message intermediary with visualization functions. We make use of a semantic configuration of message... View full abstract»

    A spherical picture is a useful way to visualise a group presentation. Spherical pictures are essentially planar, possibly nonsimple, graphs. We present a graph drawing algorithm that produces spherical pictures. The algorithm has been encompassed into a software package, SPICE, and output is presented. View full abstract»

    With recent advancements of technology, radiofrequency ablation has become one of the most used techniques to treat liver tumors. But radiologists still have to face the difficulty of planning their treatment while only relying on 2D slices acquired from CT-scan. We present a tool called RF-Sim, being part of a complete 3D reconstruction and visualization project, and including both a realistic ra... View full abstract»

    We present a 3D design visualization system that is used for substantiating design annotation behavior in a 3D world through physical models. As an experiment and development work, the visualization of 3D data is conducted through the application of a commercially available 3D printer that outputs design models with graphic instruction notes left on surfaces. Content-specific images are also left ... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (297 KB) | HTML iconHTML

    We describe a simple algorithm for level-wise enumeration of the global states of a distributed computation. In addition to fast execution, it requires working memory for only two global states plus a variable amount of memory which permits the trading of higher speed for storage. Furthermore, we present a new caching strategy that speeds up the state enumeration algorithm described in [A. Andrzej... View full abstract»

    The current ability to record neural activity within the brains of mammals has led to the production of a large body of experimental data. The analysis and comprehension of this data is key to the understanding of many basic brains functions, for example learning and memory. The main constituent of this data is multidimensional spike train recordings. As the analysis of these datasets by tradition... View full abstract»

    We present a prototypal file manager, VENNFS, that is designed to overcome some of the limitations of the current desktop interfaces, that are strongly based on hierarchical file systems. VENNFS allows users to place documents and categories on a plane so that files may belong to multiple categories at once, where proximity on the plane can represent similarity and time filtering is allowed.

  • Determining candidate binding site locations using conserved features

    Publication Year: 2003, Page(s):152 - 157
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (296 KB) | HTML iconHTML

    We present a method for representing important conserved features of a protein directly involved in binding. The conserved features are observed by noticing common atoms in proteins that bind a ligand. A method for constructing a fingerprint based upon the geometric configuration of the atoms in the binding region of the protein is presented. The fingerprint can be applied to other protein structu... View full abstract»

    We present our experiences with adapting single-user visualization software for Web-based collaboration. Sun's Java JXTA API was used to adapt an open-source molecular visualization program called Jmol. It was found that by focusing on the program's graphical user interface the software could be quickly transformed into a peer-to-peer application. Our positive experience implies that many useful s... View full abstract»

  • Trifocal morphing

    Publication Year: 2003, Page(s):24 - 29
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (732 KB) | HTML iconHTML

    Image morphing allows smooth transition between 2D images. However, one of the limitations of existing image morphing techniques is the lack of interaction - the viewpoints of the interpolated images are restrained to the line joining the optical centers of the source and the destination images. Another limitation of existing image morphing techniques is that shape warping often causes distortion ... View full abstract»

    We present a "lightweight" visual formalism that can be used to examine the state space complexity of an interface. The method can form a basis for designing, testing and documenting the 'front-end' component of a typical GUI forms based interface. The standard is intended to be free standing and seeks to address issues specific to forms based GUI interfaces. The method is based on a state transit... View full abstract»

  • Rendering recognizably unique textures

    Publication Year: 2003, Page(s):396 - 405
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1313 KB) | HTML iconHTML

    We present a perceptually designed hardware-accelerated algorithm for generating unique background textures for distinguishing documents. To be recognizable, the texture should produce a random feature vector in the brain after visual feature extraction. Our motivating example is a hypertext user interface which shows a fragment of a link's target in the margin. Upon traversing the link, the fragm... View full abstract»

    We tried to develop an interactive system that could help us recreate our conscious selves by calling on Buddhist principles, Asian philosophy, and traditional Japanese culture through the inspirational media of ink painting, kimono and haiku. "Recreating our selves" means the process of making the consciousness of our 'daily self' meet that of our 'hidden self' through rediscovering creative reso... View full abstract»

    Distributed geographic information systems typically handle large amounts of data; therefore the transmission and visualisation techniques used need to be scaleable to provide quick, interactive feedback. We introduce such techniques based on the data hierarchy (levels of detail). Namely, we describe focus-and-context visualisation and progressive transmission. The main aim is to discuss the combi...

    Different acoustic variables such as pitch, volume, timbre and position can be used to represent quantitative, qualitative and categorical aspects of the information. Such sonifications are particularly useful for those with visual impairments; they are also beneficial in circumstances where visual representations would be impossible to use or to enrich a graphical realization. We demonstrate meth... View full abstract»

    We describe a radial layout method for displaying B+-tree data structures. We present an algorithmic framework for computing the node positions that result in a planar drawing. Layout issues related to displaying the internal structure of the nodes are addressed. Each field value and associated pointer that comprises the internal structure of the node is considered a subnode. The drawin... View full abstract»

    There is now a growing awareness of the possibilities for application of natural language in the computing domain by incorporating knowledge of human-to-human interaction. We present an approach that aims to bridge the gap between scripting/storyboarding by a nontechnical creative writer and rendering characters and scenes by a graphics specialist.

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (553 KB) | HTML iconHTML

    Diffusion-limited aggregation (DLA) is a model of fractal growth. Computer models can simulate the fast aggregation of millions of particles. We propose a modified version of DLA, called semantically modified DLA (SM-DLA), for visualizing large-scale networks. SM-DLA introduces similarity measures between particles so that instead of attaching to the nearest particle in the aggregation, a new part... View full abstract»

    We introduce a novel visual bracketing method that provides detail-in-context views where the inner part contains the Focus bracketed by the context information at a lower semantic level. We demonstrate two designs for Web search result visualization that obviate the need to frequently select the next button for viewing multiple search results. View full abstract»
