      Johansson, Jimmy; Sadlo, Filip; Schreck, Tobias (The Eurographics Association, 2018)
    • Evolutionary Lines for Flow Visualization 

      Engelke, Wito; Hotz, Ingrid (The Eurographics Association, 2018)
      In this work we explore evolutionary algorithms for selected a visualization application. We demonstrate its potential using an example from flow visualization showing promising first results. Evolutionary algorithms, as ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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, ...
    • Perception-Aware Uncertainty Glyphs in the 3D Vector Fields 

      Lee, Joong-Youn; Park, Jinah (The Eurographics Association, 2018)
      We often cannot avoid value uncertainties when curating raw data to obtain a final visualization image. Although numerous studies maintain the importance of uncertainty visualization, there lack a standard means of depicting ...
    • 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 ...
    • Pressure-based Vortex Extraction in Cardiac 4D PC-MRI Blood Flow Data 

      Köhler, Benjamin; Grothoff, Matthias; Gutberlet, Matthias; Preim, Bernhard (The Eurographics Association, 2018)
      We propose a technique for vortex extraction in cardiac 4D PC-MRI blood flow data that employs an intravascular, relative pressure calculation. The method is easy to implement, runs fully automatically, and requires no ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
