    A growing body of research shows several advantages to multimodal interfaces including increased expressiveness, flexibility, and user freedom. This paper investigates the design of such an interface that integrates speech ...
  • Useful Properties of Semantic Depth of Field for Better F+C Visualization 

    Kosara, Robert; Miksch, Silvia; Hauser, Helwig (The Eurographics Association, 2002)
    This paper presents the results of a thorough user study that was performed to assess some features and the general usefulness of Semantic Depth of Field (SDOF). Based on these results, concrete hints are given on how SDOF ...
  • Viewpoint Entropy: A New Tool for Obtaining Good Views of Molecules 

    Vázquez, Pere-Pau; Feixas, Miquel; Sbert, Mateu; Llobet, Antoni (The Eurographics Association, 2002)
    The computation of good viewpoints is important in several fields: computer graphics, removal of degeneracies in computational geometry, robotics, graph drawing, etc. However, in areas such as computer graphics there is ...
  • Volume Rendering Multivariate Data to Visualize Meteorological Simulations: A Case Study 

    Kniss, Joe; Hansen, Charles (The Eurographics Association, 2002)
    High resolution computational weather models are becoming increasing complex. However, the analysis of these models has not benefited from recent advancements in volume visualization. This case study applies the ideas and ...
  • Visualizing and Investigating Multidimensional Functions 

    Santos, S. R. dos; Brodlie, K. W. (The Eurographics Association, 2002)

  • Visualization of Bibliographic Networks with a Reshaped Landscape Metaphor 

    Brandes, U.; Willhalm, T. (The Eurographics Association, 2002)
    We describe a novel approach to visualize bibliographic networks that facilitates the simultaneous identification of clusters (e.g., topic areas) and prominent entities (e.g., surveys or landmark papers). While employing ...
  • Secondary Task Display Attributes - Optimizing Visualizations for Cognitive Task Suitability and Interference Avoidance 

    Chewar, C. M.; McCrickard, D. Scott; Ndiwalana, Ali; North, Chris; Pryor, Jon; Tessendorf, David (The Eurographics Association, 2002)
    We found that established display design guidelines for focal images cannot be extended to images displayed as a secondary task in a dual-task situation. This paper describes an experiment that determines a new ordering ...
  • Bag-of-Particles as a Deformable Model 

    Stahl, D.; Ezquerra, N.; Turk, G. (The Eurographics Association, 2002)
    We present an interactive, physically-based, elastically deformable model using a particle system to model surfaces with interior volumes that can be haptically felt. Oriented particles used in existing surface-only models, ...
  • A Continuous Skeletonization Method Based on Level Sets 

    Rumpf, Martin; Telea, Alexandru (The Eurographics Association, 2002)

    Morris, Christopher J.; Ebert, David (The Eurographics Association, 2002)
    Traditionally, volume rendering of medical data has been comprised of transfer functions that map a scalar value, usually a MRI or CT intensity, to an opacity. Corresponding color maps are either selected regardless of the ...
