    • Perceptual Evaluation of Ghosted View Techniques for the Exploration of Vascular Structures and Embedded Flow 

      Baer, Alexandra; Gasteiger, Rocco; Cunningham, Douglas; Preim, Bernhard (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      This paper presents three controlled perceptual studies investigating the visualization of the cerebral aneurysm anatomy with embedded flow visualization. We evaluate and compare the common semitransparent visualization ...

    • Piecewise Laplacian-based Projection for Interactive Data Exploration and Organization 

      Paulovich, Fernando V.; Eler, D. M.; Poco, J.; Botha, Charl P.; Minghim, R.; Nonato, L. G. (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Multidimensional projection has emerged as an important visualization tool in applications involving the visual analysis of high-dimensional data. However, high precision projection methods are either computationally ...

    • A User Study of Visualization Effectiveness Using EEG and Cognitive Load 

      Anderson, Erik W.; Potter, K. C.; Matzen, L. E.; Shepherd, J. F.; Preston, G. A.; Silva, C. T. (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Effectively evaluating visualization techniques is a difficult task often assessed through feedback from user studies and expert evaluations. This work presents an alternative approach to visualization evaluation in which ...
