      Tian, Xingze; Günther, Tobias (The Eurographics Association, 2020)
      Integral surfaces are a useful method in illustrative and geometry-based flow visualization, as they convey shading, depth and geometric information better than their line-based counterparts. However, they are not as ...
    • Investigating the Role of Locus of Control in Moderating Complex Analytic Workflows 

      Crouser, R. Jordan; Ottley, Alvitta; Swanson, Kendra; Montoly, Ananda (The Eurographics Association, 2020)
      Throughout the last decade, researchers have shown that the effectiveness of a visualization tool depends on the experience, personality, and cognitive abilities of the user. This work has also demonstrated that these ...

      Guo, Grace; Dy, Bianchi; Ibrahim, Nazim; Joyce, Sam Conrad; Poorthuis, Ate (The Eurographics Association, 2020)
      In this paper, we replicate a foundational study in graphical perception, and compare our findings from using design-centric participants with that of previous studies. We also assess the visual accuracy of two groups, ...
    • Characterizing Exploratory Behaviors on a Personal Visualization Interface Using Interaction Logs 

      Sukumar, Poorna Talkad; Martinez, Gonzalo J.; Grover, Ted; Mark, Gloria; D'Mello, Sidney K.; Chawla, Nitesh V.; Mattingly, Stephen M.; Striegel, Aaron D. (The Eurographics Association, 2020)
      Personal visualizations present a separate class of visualizations where users interact with their own data to draw inferences about themselves. In this paper, we study how a realistic understanding of personal visualizations ...
    • Interactive Creation of Perceptually Uniform Color Maps 

      Lambers, Martin (The Eurographics Association, 2020)
      A large number of design rules have been identified for color maps used in Scientific Visualization. One of the most important of these is perceptual uniformity, which at the same time is one of the hardest to guarantee ...
    • Exploring Time Series Segmentations Using Uncertainty and Focus+Context Techniques

      Time series segmentation is employed in various domains and continues to be a relevant topic of research. A segmentation pipeline is composed of different steps involving several parameterizable algorithms. Existing Visual ...
    • Design of a Real Time Visual Analytics Support Tool for Conflict Detection and Resolution in Air Traffic Control 

      Zohrevandi, Elmira; Westin, Carl A. L.; Lundberg, Jonas; Ynnerman, Anders (The Eurographics Association, 2020)
      Air traffic control is a safety critical high-risk environment where operators need to analyse and interpret traffic dynamics of spatio-temporal data in real-time. To support the air traffic controller in safely separating ...
