    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»

    The need for visualisation applications developed for small handheld devices such as PDAs and intelligent mobiles are growing. A visual user interface VUI model based on zooming user interface techniques (ZUI), to adapt two complete different visualisation application areas; online brand shopping and flood warning system for PDAs, is presented. The online brand shopping was evaluated in a benchmar... View full abstract»

    Augmented reality (AR) systems need to be evaluated for their appropriateness for a given task. Three approaches are used to evaluate the waterpump augmented reality tool (WART). The system is assessed using verbal protocol, performance time and a questionnaire. The WART system is compared with a paper version of the assembly instructions. The verbal protocol revealed that there was more cognitive... View full abstract»

    When professionals are given the task of analyzing a domain, it is likely that it is not the first time this task has been done. Rather than build upon what is already done they will often redo the work. The key problem that sustains this repetition of effort is the lack of a standard and centralized way to communicate and share the knowledge that results from the analysis. Software architecture f...

    We introduce a new edge length heuristic that finds a graph layout where the edge lengths are proportional to the weights on the graph edges. The heuristic can be used in combination with the spring embedder to produce a compromise between a drawing with an accurate presentation of edge length and a drawing with good general comprehensibility. We describe our preliminary investigations in combinin... View full abstract»

    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»

    Visualization of transportation projects has been shown to be a very effective way of communicating information between interested project parties [Keister, M. et al., (2002)]. In reviewed applications, visualization has been used primarily for communicating information on the geometric design, or as photorealistic representations that place transportation projects within their existing or envisio...

    The transfer of knowledge from research laboratories and academic seminars to the industrial/commercial sector is a strategically important issue. Text analysis of journal papers and patent documents, written by one scientist and his team in the specialist area of semiconductor physics, has been performed in order to visualize the cross-over of research knowledge onto patented artifacts. The resul... View full abstract»

    An essential characteristic of design communication is the need to talk about things (objects and concepts). We concern the development of a practical method to assist the iterative development of computer-mediated communication (CMC) systems that support talk by designers working co-operatively over distance. Previous approaches to the study of CMC systems limit the extent to which the value of n... 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»

    In literature exist many links to translation of speech into sign language and links to gesturing with avatars. But we cannot get any link to a visualization of background knowledge which deaf people are lacking. The author himself is hearing impaired. Therefore he knows of the importance of a good visualization of information needed to get the correct mental model. He claims that gesturing with a... View full abstract»

    A large amount of strategically relevant business information is contained in unstructured texts. While information brokering approaches are used to contextualize such documents and to generate metadata, text mining is used to explore large document spaces. So far, little attention has been paid on a value-adding combination of these technologies. We show how metadata and documents can be compleme... View full abstract»

    A prototype transition path editing tool for use in an immersive environment has been developed, which can be used for 3D keyframe animation authoring and editing of 3D transition paths. Authoring tools using 2D GUI is normally used to develop 3D animation. However, it is more direct to create 3D contents in a 3D space than in a 2D GUI. Therefore hand direct manipulation is employed to utilize bod... View full abstract»

    We present two case studies in which the objective was to accurately reconstruct a historically significant place no longer accessible to the public due to complete or partial destruction of the original environment. In both cases the desire was to present the reconstructions in a public venue for the purpose of enlightenment; to engage the audience in a deeper understanding of the information bei...

    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...

    The Stardinates are a novel interactive information visualization (InfoVis) technique, which aims at visualizing highly structured data. They represent some Gestalt principles very well, especially the principles of Closure and 'Pragnanz'. As a consequence, Stardinates form very distinct and memorable patterns, which make abstraction and aggregation much easier. We give a formal description of the... View full abstract»
