    Dealing with visualizations containing large data set is a challenging issue and, in the field of information visualization, almost every visual technique reveals its drawback when visualizing large number of items. To deal with this problem we introduce a formal environment, modeling in a virtual space the image features we are interested in (e.g, absolute and relative density, clusters, etc.) an...

    Visualization of recursively defined concepts is a general problem that appears in many areas. For example, drought areas based on the standardized precipitation index (SPI) and long-term air pollution areas based on safe and critical level standards are recursively defined concepts. We develop a general and efficient representation and visualization method for recursively defined spatio-temporal ... View full abstract»

    This work reports on ongoing work related to the representation of hierarchical structures using multiple synthetic voices. We manipulated three synthetic voice parameters, average pitch, pitch range and speech rate, to represent nodes in a hierarchy. We created hierarchies containing 10 nodes and three levels deep. A within-subjects design (N=12) was conducted to compare the effect of multiple sy... View full abstract»

    It is speculated that the processing of different types of information (e.g., quantitative, ordinal, or nominal data) will be affected by what type of visual display is used to present that information (e.g.. line graphs, shapes with varying levels of gray saturation, or shapes of different colors). People are expected to be able to more efficiently and accurately process and answer questions abou... View full abstract»

    To help programmers debug visual programs, we propose an animated execution method with supporting functions to be used with the animated execution. The animated execution animates state transitions as the program is executed. To make it easy for the programmer to interpret the animation, it is displayed in a manner similar to the visual program. The functions are used to narrow the possible locat... View full abstract»

    This paper presents a technique, the Quantum Web Field, designed to give an ambient visualisation of the current activity on a Web site. It uses the paths of past visitors to the site and a self-organising map to build a diffuse 'probabilistic' mapping of pages to cells in a 2D matrix, where highly traversed page-links tend to be closer to each other. The paths of current visitors appear as intell... View full abstract»

    In This work we present an approach using incrementally constructed neural gas networks to 'grow' an intuitive interface for interactive exploratory sonification of high-dimensional data. The sonifications portray information about the intrinsic data dimensionality and its variation within the data space. The interface follows the paradigm of model-based sonification and consists of a graph of nod... View full abstract»

    3D features of urban scenes are the most important basic elements, we present a method for extracting 3D features of urban scenes from ground-based laser range data. We give depth image representation, define vertical and horizontal scanline, and remove the invalid data including trees, cables, fences, cars, passers-by, outlies and so on. We employ local self-adaptive curve fitting to extract line... View full abstract»

    When planning a Leksell GammaKnife® treatment, dose planners place iso-centres of the irradiation field in such a way that a certain iso-dose surface conforms as closely as possible to a target, such as a tumour. Today this planning is done primarily in 2D, and the clinician places the iso-centres onto the current medical image. The images used are usually acquired by MRl, CT or angiography. I...

    One of the first questions we pose when we have a new data set to explore is: are there any obvious groupings in the data? These clusters reveal the structure of the data set and make the data easier to understand. Cluster analysis is a classic problem and there are many tools for it. The problem is that these methods often give conflicting and too fine-grained results for practical use. As well, ... View full abstract»

    One aspect of non-visual visualisation is providing accessibility to diagrams for users with visual impairments. In this paper, we review the literature on diagrams and non-visual presentation in order to elucidate the issues involved in making graph based diagrams accessible using speech and non-speech sound. First we examine the nature, scope and uses of these diagrams. We then describe the natu... View full abstract»

    Recently researchers have been interested in non-visual forms of presentation. Sound, touch, smell, as well as vision can be used to depict information. One important medium is sound; it can encode information for the blind or partial sighted, used to display information when it is impossible to use a screen, and the hardware is cheap and widely available. Researchers have investigated sonifying v... View full abstract»
