  • Risk Fixers and Sweet Spotters: a Study of the Different Approaches to Using Visual Sensitivity Analysis in an Investment Scenario 

    Torsney-Weir, Thomas; Afroozeh, Shahrzad; Sedlmair, Michael; Möller, Torsten (The Eurographics Association, 2018)
    We present an empirical study that illustrates how individual users' decision making preferences and biases influence visualization design choices. Twenty-three participants, in a lab study, were shown two interactive ...
  • Touch the Time: Touch-Centered Interaction Paradigms for Time-Oriented Data 

    Riehmann, Patrick; Reibert, Joshua; Opolka, Jens; Froehlich, Bernd (The Eurographics Association, 2018)
    We present novel direct-touch centered paradigms for exploring time series data visualized in a coordinated multi-view display. The views can be easily and flexibly configured by choosing from various adapted or enhanced ...
  • DiffPin: Interactive Specification of References for Comparative Small-Multiple Displays 

    Spechtenhauser, Florian; Piringer, Harald (The Eurographics Association, 2018)
    Small-multiple displays are frequently used for visual comparison by juxtaposition. Explicitly encoding differences between cells enables to convey also minor differences in the data, but requires to specify references for ...
  • Pixel Wise Pie Charts: Placement of Data Points Visualizing Spatial Value Distributions 

    Janetzko, Halldor; Stein, Manuel (The Eurographics Association, 2018)
    Handling overplotted points in spatial pixel-based visualizations is usually done either by aggregation or sampling. The third rather unusual alternative is replacing data items untangling overplotted regions. Depending ...
  • Learning from the Best - Visual Analysis of a Quasi-Optimal Data Labeling Strategy 

    Bernard, Jürgen; Hutter, Marco; Lehmann, Markus; Müller, Martin; Zeppelzauer, Matthias; Sedlmair, Michael (The Eurographics Association, 2018)
    An overarching goal of active learning strategies is to reduce the human effort when labeling datasets and training machine learning methods. In this work, we focus on the analysis of a (theoretical) quasi-optimal, ...
  • Exploring Interactive Linking Between Text and Visualization 

    Latif, Shahid; Liu, Diao; Beck, Fabian (The Eurographics Association, 2018)
    Visualizations are included in documents as augmentation to text and they become more intuitive if readers have the ability to interact with them. Modern web technologies facilitate the development of interactive documents ...
  • STEIN: Speeding up Evaluation Activities With a Seamless Testing Environment INtegrator 

    Angelini, Marco; Blasilli, Graziano; Lenti, Simone; Santucci, Giuseppe (The Eurographics Association, 2018)
    The evaluation of an information visualization system is a complex activity, involving the understanding of both the visualization itself and the process that it is meant to support. Moreover, if the evaluation activity ...
  • Using a Task Classification in the Visualisation Design Process for Task Understanding and Abstraction: an Empirical Study 

    Kerracher, Natalie; Kennedy, Jessie B.; Chalmers, Kevin (The Eurographics Association, 2018)
    Task classifications are widely purported to be useful in the design process, with various suggestions having been made for their use at the different stages. However, little has been written regarding the actual use of ...
  • Issues and Suggestions for the Development of a Biodiversity Data Visualization Support Tool 

    Kaur, Pawandeep; Klan, Friederike; König-Ries, Birgitta (The Eurographics Association, 2018)
    Visualizations are an important tool to transport information. However, finding the right visualization can be challenging. Using the biodiversity research domain as a showcase, we investigate where exactly these challenges ...
  • Sketching Temporal Uncertainty - An Exploratory User Study 

    Schwarzinger, Fabian; Roschal, Andreas; Gschwandtner, Theresia (The Eurographics Association, 2018)
    Real world datasets frequently contain inherent uncertainty of some kind. Most of the work in the context of visualizing temporal uncertainty, focus on evaluating and comparing different visualization approaches. This ...
  • TapVis: A Data Visualization Approach for Assessment of Alternating Tapping Performance in Patients with Parkinson's Disease 

    Jusufi, Ilir; Memedi, Mevludin; Nyholm, Dag (The Eurographics Association, 2018)
    Advancements in telemedicine have been helpful for frequent monitoring of patients with Parkinson's disease (PD) from remote locations and assessment of their individual symptoms and treatment-related complications. These ...
  • VisGuides: A Forum for Discussing Visualization Guidelines 

    Diehl, Alexandra; Abdul-Rahman, Alfie; El-Assady, Mennatallah; Bach, Benjamin; Keim, Daniel; Chen, Min (The Eurographics Association, 2018)
    This paper presents VisGuides, a discussion platform to facilitate the collection, evaluation, critique, revision, and dissemination of visualization guidelines. As visualization becomes a more widespread discipline with ...
  • ChemoExplorer: A Dashboard for the Visual Analysis of Chemotherapy Response in Breast Cancer Patients 

    Karall, Nikolaus; Gröller, Eduard; Raidou, Renata Georgia (The Eurographics Association, 2018)
    In breast cancer chemotherapy treatment, different alternative strategies can be employed. Clinical researchers working on the optimization of chemotherapy strategies need to analyze the progress of the treatment and to ...
  • Improving Provenance Data Interaction for Visual Storytelling in Medical Imaging Data Exploration 

    Amabili, Lorenzo; Kosinka, Jiri; Meersbergen, Maarten A. J. van; Ooijen, Peter M. A. van; Roerdink, Jos B. T. M.; Svetachov, Pjotr; Yu, Lingyun (The Eurographics Association, 2018)
    Effective collaborative work in diagnostic medical imaging is not trivial due to the large amounts of complex data involved, a (non-linear) workflow involving experts in different domains, and a lack of versatility in the ...
  • Comparative Visual Analysis of Pelvic Organ Segmentations 

    Reiter, Oliver; Breeuwer, Marcel; Gröller, Eduard; Raidou, Renata Georgia (The Eurographics Association, 2018)
    In prostate cancer treatment, automatic segmentations of the pelvic organs are often used as input to radiotherapy planning systems. However, natural anatomical variability of the involved organs is a common reason, for ...
  • Visual Analysis of Parallel Interval Events 

    Qi, Ji; Liu, Cong; Cappers, B. C. M. (Bram); Wetering, Huub van de (The Eurographics Association, 2018)
    System logs typically contain lines with time stamps that each describes an event. Where these events semantically form start and end events, they can be combined into interval events. For visual event analytics, the ...
  • Visualizing Functional Regions by Analysis of Geo-textual Data 

    Wang, Yunzhe; Baciu, George; Li, Chenhui (The Eurographics Association, 2018)
    Using tremendous geo-textual data collected from social media applications, we facilitate the analysis of region functions. By extracting semantics from textual properties, we aim at classifying geographical locations in ...
  • Colored Stochastic Shadow Mapping for Direct Volume Rendering 

    Weidner, Johannes; Linsen, Lars (The Eurographics Association, 2018)
    Creating direct volume renderings with shadows can lead to a better perception of the rendered images. Deep shadow maps is an effective and efficient approach to compute shadows at interactive rates. We propose an alternative ...
