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

    Författare :Lars Winkler Pettersson; Stefan Seipel; Anders Jansson; Oliver Bimber; Uppsala universitet; []
    Nyckelord :Visualization; Human-Computer Interaction; Collaboration; Co-located Visualization; Computer Supported Cooperative Work;

    Sammanfattning : 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.

  2. 2. Sentiment and Stance Visualization of Textual Data for Social Media

    Författare :Kostiantyn Kucher; Andreas Kerren; Carita Paradis; Magnus Sahlgren; Ross Maciejewski; Linnéuniversitetet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; stance visualization; sentiment visualization; text visualization; stance analysis; sentiment analysis; opinion mining; visualization; interaction; visual analytics; NLP; text mining; text analytics; social media; Informations- och programvisualisering; Information and software visualization;

    Sammanfattning : Rapid progress in digital technologies has transformed the world in many ways during the past few decades, in particular, with the new means of communication such as social media. Social media platforms typically rely on textual data produced or shared by the users in multiple timestamped posts. LÄS MER

  3. 3. Visualization of Causal Relations

    Författare :Niklas Elmqvist; Chalmers University of Technology; []
    Nyckelord :information visualization; causality visualization; citation network visualization; causal relations;

    Sammanfattning : 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. LÄS MER

  4. 4. User-Centered Collaborative Visualization

    Författare :Daniel Cernea; Andreas Kerren; Achim Ebert; Helen C. Purchase; Linnéuniversitetet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; collaborative information visualization; computer-supported cooperative work CSCW ; user-centered design; emotion visualization; affective user interface; tabletop; touch surfaces; nestable tangibles; subjective evaluation; Information and software visualization; Informations- och programvisualisering; Computer Science; Datavetenskap;

    Sammanfattning : The last couple of years have marked the entire field of information technology with the introduction of a new global resource, called data. Certainly, one can argue that large amounts of information and highly interconnected and complex datasets were available since the dawn of the computer and even centuries before. LÄS MER

  5. 5. 3D Occlusion Management and Causality Visualization

    Författare :Niklas Elmqvist; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; causality; occlusion reduction; interaction techniques; visualization; occlusion management; information visualization; causal relations;

    Sammanfattning : 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.
