    • Choosing the Right Sample? Experiences of Selecting Participants for Visualization Evaluation 

      Kriglstein, Simone; Pohl, Margit (The Eurographics Association, 2015)
      Conducting and reporting evaluation studies has become more and more popular over the last few years in the information visualization community. A big challenge is to describe such studies in a way such that the investigations ...
    • Classifying Medical Projection Techniques based on Parameterization Attribute Preservation 

      Kreiser, Julian; Ropinski, Timo (The Eurographics Association, 2016)
      In many areas of medicine, visualization researchers can help by contributing to to task simplification, abstraction or complexity reduction. As these approaches, can allow a better workflow in medical environments by ...
    • A Crowdsourced Approach to Colormap Assessment 

      Turton, Terece L.; Ware, Colin; Samsel, Francesca; Rogers, David H. (The Eurographics Association, 2017)
      Despite continual research and discussion on the perceptual effects of color in scientific visualization, psychophysical testing is often limited. In-person lab studies can be expensive and time-consuming while results can ...
    • Debugging Vega through Inspection of the Data Flow Graph 

      Hoffswell, Jane; Satyanarayan, Arvind; Heer, Jeffrey (The Eurographics Association, 2015)
      Vega is a declarative visualization grammar that decouples specification from execution to allow users to focus on the visual representation rather than low-level implementation decisions. However, this representation comes ...
    • Detection of Confirmation and Distinction Biases in Visual Analytics Systems 

      Nalcaci, Atilla Alpay; Girgin, Dilara; Balki, Semih; Talay, Fatih; Boz, Hasan Alp; Balcisoy, Selim (The Eurographics Association, 2019)
      Cognitive bias is a systematic error that introduces drifts and distortions in the human judgment in terms of visual decomposition in the direction of the dominant instance. It has a significant role in decision-making ...
    • Detection of Diabetic Neuropathy - Can Visual Analytics Methods Really Help in Practice? 

      Röhlig, Martin; Stachs, Oliver; Schumann, Heidrun (The Eurographics Association, 2016)
      Visual analytics (VA) methods are valuable means for supporting the detection of diabetic neuropathy, the most common longterm complication of diabetes mellitus. We suggest two strategies for strengthening reliability, ...
    • EuroRV3 2016: Frontmatter 

      Kai Lawonn; Mario Hlawitschka; Paul Rosenthal (Eurographics Association, 2016)
    • EuroRV3 2017: Frontmatter 

      Lawonn, Kai; Smit, Noeska; Cunningham, Douglas (Eurographics Association, 2017)
    • EuroRV3 2018: Frontmatter 

      Kai Lawonn; Noeska Smit; Lars Linsen; Robert Kosara (The Eurographics Association, 2018)
    • Evaluating the Perceptual Uniformity of Color Sequences for Feature Discrimination 

      Ware, Colin; Turton, Terece L.; Samsel, Francesca; Bujack, Roxana; Rogers, David H. (The Eurographics Association, 2017)
      Probably the most common method for visualizing univariate data maps is through pseudocoloring and one of the most commonly cited requirements of a good colormap is that it be perceptually uniform. This means that differences ...
    • Examining the Components of Trust in Map-Based Visualizations 

      Xiong, Cindy; Padilla, Lace M. K.; Grayson, Kent; Franconeri, Steven (The Eurographics Association, 2019)
      Prior research suggests that perceived transparency is often associated with perceived trust. For some data types, greater transparency in data visualization is also associated with an increase in the amount of information ...
    • Experiences on Validation of Multi-Component System Simulations for Medical Training Applications 

      Law, Yuen C.; Weyers, Benjamin; Kuhlen, Torsten W. (The Eurographics Association, 2016)
      In the simulation of multi-component systems, we often encounter a problem with a lack of ground-truth data. This situation makes the validation of our simulation methods and models a difficult task. In this work we present ...
    • From a User Study to a Valid Claim: How to Test Your Hypothesis and Avoid Common Pitfalls 

      Hoon, Niels H. L. C. de; Eisemann, Elmar; Vilanova, Anna (The Eurographics Association, 2017)
      The evaluation of visualization methods or designs often relies on user studies. Apart from the difficulties involved in the design of the study itself, the existing mechanisms to obtain sound conclusions are often unclear. ...
    • Frontmatter: EuroRV3 2015 EuroVis Workshop on Reproducibility, Verification, and Validation in Visualization 

      Rosenthal, Paul; Aigner, Wolfgang; Scheidegger, Carlos (Eurographics Association, 2015)
    • Gaze into Hierarchy: A Practice-oriented Eye Tracking Study 

      Müller, N. H.; Liebold, B.; Pietschmann, D.; Ohler, P.; Rosenthal, P. (The Eurographics Association, 2013)
      The visualization of hierarchical data is a wide field and plenty of different approaches have been proposed for various applications and purposes. A comprehensive survey on hierarchy visualizations was recently presented ...
    • Guidelines and Recommendations for the Evaluation of New Visualization Techniques by Means of Experimental Studies 

      Luz, Maria; Lawonn, Kai; Hansen, Christian (The Eurographics Association, 2017)
      This paper addresses important issues in the evaluation of new visualization techniques. It describes the principle of quantitative research in general and presents the idea of experimental studies. The goal of experimental ...
    • High-Performance Motion Correction of Fetal MRI
