  1. 1. Algorithmically Guided Information Visualization Explorative Approaches for High Dimensional, Mixed and Categorical Data

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Sara Johansson Fernstad; Linköpings universitet.; Linköpings universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Information visualization; data mining; high dimensional data; categorical data; mixed data;

    Abstract : Facilitated by the technological advances of the last decades, increasing amounts of complex data are being collected within fields such as biology, chemistry and social sciences. The major challenge today is not to gather data, but to extract useful information and gain insights from it. READ MORE

  2. 2. Visualization of Causal Relations

    University dissertation from Chalmers University of Technology

    Author : Niklas Elmqvist; Chalmers tekniska högskola.; Chalmers University of Technology.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Informationsteknik; Information technology; causality visualization; causal relations; citation network visualization; information visualization;

    Abstract : The notion of cause and effect is pervasive in human thinking and plays a significant role in our perception of time. Software systems, in particular parallel and distributed ones, are permeated by this causality, and the human mind is especially well-suited to detect instances of this concept. READ MORE

  3. 3. Image Based Visualization Methods for Meteorological Data

    University dissertation from Institutionen för teknik och naturvetenskap

    Author : Björn Olsson; Linköpings universitet.; Linköpings universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Visualization; Meteorological Data; Artificial Neural Networks; High-Dynamic-Range images; Satellite Data; Classification; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap;

    Abstract : Visualization is the process of constructing methods, which are able to synthesize interesting and informative images from data sets, to simplify the process of interpreting the data. In this thesis a new approach to construct meteorological visualization methods using neural network technology is described. READ MORE

  4. 4. Collaborative Visualization Designing and evaluating systems for co-located work

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Lars Winkler Pettersson; Uppsala universitet.; Uppsala universitet.; [2008]
    Keywords : Visualization; Human-Computer Interaction; Collaboration; Co-located Visualization; Computer Supported Cooperative Work;

    Abstract : This thesis investigates new ways of using information visualization to support collaboration in co-located work. To study this phenomenon, Multiple Viewer Display Environments (MVDEs) with independent views have been applied to present information such that all viewers at the same time and in the same display can see correct views of 3D models, see correctly oriented text and see different parts and aspects of information in each view.

  5. 5. 3D Occlusion Management and Causality Visualization

    University dissertation from Chalmers University of Technology

    Author : Niklas Elmqvist; Chalmers tekniska högskola.; Chalmers University of Technology.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Computer science; occlusion management; occlusion reduction; visualization; information visualization; interaction techniques; causality; causal relations;

    Abstract : This thesis is split into two parts: one part dealing with the management of occlusion in 3D environments, the other with the visualization of causal relations. Both of these parts fall within the general framework of visualization---the graphical representation of data (abstract or concrete) with the purpose of amplifying cognition---but they do so in different ways.
