    We present a new framework for metadata visualisation systems called VisMeB (visual metadata browser). It is based upon redesign ideas from the IN-SYDER system that were come under extensive evaluations. The aim of our approach is to improve the process of finding relevant information in an intuitive yet multifunctional way. We use a ScatterPlot in combination with a so called SuperTable for visua...

  • The argument-as metaphor in decision-making visualisation

    Publication Year: 2003, Page(s):596 - 599
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (396 KB) | HTML iconHTML

    We describe 'argument-as' metaphors and how they may be used as a vehicle to visualise decision support information. We argue that our approach is particularly useful for users who may not have advanced computing skills, and who have little time to dedicate to in-depth analysis of the information. We present an interface which, as a result of using an argument-as metaphorical approach, is simple t... View full abstract»

    For visual perception of 3D models, shading plays one of the major roles. The shading quality of level-of-detail models is limited generally because existing LOD algorithms assume a conceptually smooth surface. A complex mesh, however, is likely to have conceptually smooth and angular parts. We introduce an extension to the progressive mesh LOD approach that efficiently handles triangle meshes wit...

    We describe a visualisation tool, VlUM, designed to support users in scrutinising models of their interests, preferences and knowledge. We also describe MECUREO, a tool for building lightweight ontologies from online dictionaries. It enables a user to see a model describing both their interests and additional analogically inferred interests. We report a small qualitative evaluation of this combine... 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»

    Extracting actionable insight from large high dimensional data sets, and its use for more effective decision-making, has become a pervasive problem across many fields in research and industry. We describe an investigation of the application of tightly coupled statistical and visual analysis techniques to this task. The approach we choose is "unsupervised learning" where we investigate the advantag... View full abstract»

    We describe a cognitive architecture to evaluate visualization applications (CAEVA). This architecture requires gathering domain knowledge to adapt existing evaluation models to new domains and applications. This architecture has two main components: one for interoperability and one for cognitive models. The interoperability component uses client-server protocols. The cognitive component includes ...

    The process of analyzing and using information is often collaborative in nature especially given the broad and multidisciplinary tasks that we must support today. Collaboration requires people to share "common ground", which is the knowledge that enables them to communicate and, more generally, to coordinate their activities. Common ground has been explored in a variety of systems, domains, and di... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (443 KB) | HTML iconHTML

    A method of increasing the realism of nonverbal interaction in 3D is proposed. The method is aimed at creating truly believable autonomous actors in virtual environments. A simple action-reaction interaction model with a predefined set of actions is used. The actions are recognised using weighted-directed graphs (Markov models), using a set of control points as features to reduce the dimensionalit... View full abstract»

    Implicit information embedded in semantic Web graphs, such as topography, clusters, and disconnected subgraphs is difficult to extract from text files. Visualizations of the graphs can reveal some of these features, but existing systems for visualizing metadata focus on aspects other than understanding the greater structure. We present a tool for generating visualizations of ontologies and metadat... View full abstract»

  • Visual simulation of refraction phenomena in the Earth's atmosphere

    Publication Year: 2003, Page(s):452 - 457
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (388 KB) | HTML iconHTML

    We present a simple method for visual simulation of refraction phenomena in the Earth's atmosphere. The method divides the atmosphere into a set of spherical layers and the rays are approximated by circular arcs within the layers. The curvature of arcs is related to the variations of the refractive index. The path of the ray through the atmosphere is found by intersecting the circular arcs with th... View full abstract»

    We introduce a matrix based 'visual reference system model' for architectural heritage. The system consists of multilayered Web pages containing visual and textual data about architectural periods, styles and elements. The structure of the system may be adapted to various architectural concepts and periods. Yet, it is flexible enough to be limited down to a specific period or architect only. The m...

    We present an aesthetics based method for drawing Euler diagrams. Aesthetic layout metrics have been found to be useful in graph drawing algorithms, which use metrics motivated by aesthetic principles that aid user understanding of diagrams. We have taken a similar approach to Euler diagram drawing, and have defined a set of suitable metrics to be used within a hill climbing multicriteria optimise... View full abstract»

    We suggest a set of visualization-based exploratory tools to support analysis and comparison of different spatial development scenarios, such as results of simulation of various spatially related processes. We have applied a task-analytical approach to tool selection and design, that is, we have first considered what analytical tasks may potentially emerge in the course of investigating and compar...

    Visual metaphors describe cognitive processes in every part of life and function as a connection between what we see and what we think. Mental activities and perceptional interactions of the real world are often interdependent and occur mutually. Cognition is enhanced by the use of the real world, in particular the use of cognitive artifacts or physical inventions (S. K. Card, et al., 1999). We de... View full abstract»

    We present a new framework for the use of virtual reality (VR) in engineering design for configuration applications. Traditional VR systems support the visual exploration of a design solution but do not assist the user in exploring alternative solutions based on domain knowledge. Extending previous work in the area of intelligent virtual environment, we propose an intelligent configuration system ... View full abstract»

    The ray tracing algorithm produces realistic high quality images, but it requires a long time for calculation on a single processor machine, which limits its practical use. With the development of distributed object architectures, such as CORBA (Common Object Request Broker), the most promising way to improve ray traced picture productions seems to be parallelisation, which offers both increased C...

    We describe a graph visualization method that attempts to aid the understanding of graphs by adding continuous local movement to graph diagrams. We include a discussion of some of the many different kinds of potential graph movement and then describe an empirical trial that was conducted to investigate whether one kind of movement helps with a particular graph comprehension task.

    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...
