  • Spotlight Interest Management for Distributed Virtual Environments 

    Dunwell, Ian; Whelan, John C. (The Eurographics Association, 2008)
    This paper presents a novel refinement to visual attention-based interest management in distributed virtual environments (VEs). It is suggested that in the context of a desktop VE where only limited immersion occurs, using ...
  • Effect of the Size of the Field of View on the Perceived Amplitude of Rotations of the Visual Scene 

    Ogier, Maelle; Bülthoff, Heinrich H.; Bresciani, Jean-Pierre (The Eurographics Association, 2008)
    Efficient navigation requires a good representation of body position/orientation in the environment and an accurate updating of this representation when the body-environment relationship changes. We tested here whether the ...
  • Display Devices for Virtual Environments: Impact on Performance, Workload, and Simulator Sickness 

    Conradi, Jessica; Alexander, Thomas (The Eurographics Association, 2008)
    Usability and, thus, success of Virtual Environments (VE) systems are closely related to the type of display used. Applicable VE-displays range from simple desktop monitors with low immersion to high-end, immersive HMDs. ...
  • The Influence of Head Tracking and Stereo on User Performance with Non-Isomorphic 3D Rotation 

    Jr., Joseph J. LaViola; Forsberg, Andrew S.; Huffman, John; Bragdon, Andrew (The Eurographics Association, 2008)
    We present an experimental study that explores how head tracking and stereo viewing affect user performance when rotating 3D virtual objects using isomorphic and non-isomorphic rotation techniques. Our experiment com- pares ...
  • Tangible Interaction for 3D Widget Manipulation in Virtual Environments 

    Kruszynski, Krzysztof J.; Liere, Robert van (The Eurographics Association, 2008)
    In this paper we explore the usage of tangible controllers for the manipulation of 3D widgets in scientific visualization applications. Tangible controllers can be more efficient than unrestricted 6-DOF devices, since many ...
  • Using Teleporting, Awareness and Multiple Views to Improve Teamwork in Collaborative Virtual Environments 

    Dodds, Trevor J.; Ruddle, Roy A. (The Eurographics Association, 2008)
    Mobile Group Dynamics (MGDs) are a suite of techniques that help people work together in large-scale col- laborative virtual environments (CVEs). The present paper describes the implementation and evaluation of three ...
  • Interactive and Accurate Collision Detection in Virtual Orthodontics 

    Rodrigues, Maria Andréia F.; Rocha, Rafael S.; Silva, Wendel B. (The Eurographics Association, 2008)
    An interactive computer-based training tool for using in Orthodontics is aimed at students and experienced professionals who need to predict orthodontic treatment outcomes, including the determination whether and where the ...
  • Integrating Particle Dispersion Models into Real-time Virtual Environments 

    Willemsen, Peter; Norgren, Andrew; Singh, Balwinder; Pardyjak, Eric R. (The Eurographics Association, 2008)
    We present a system for interacting with fast response particle dispersion models in a real-time virtual envi- ronment. The particle simulation system is used as both an engineering tool for modeling and understanding ...
  • miniCAVE - A Fully immersive Display System Using Consumer Hardware 

    Schlechtweg, Stefan (The Eurographics Association, 2008)
    We present the design and construction of a small scale CAVE that employs active stereo using shutter glasses for viewing as well as for projection. It is controlled by a single server with four graphics boards. The main ...
  • Camera Calibration of a NintendoWii Remote using PA-10 Robotic Arms 

    Grimes, Holly S.; Ferguson, Robin Stuart; McMenemy, Karen (The Eurographics Association, 2008)
    The Remote control unit for the Nintendo Wii computer games console features an infrared camera capable of detecting up to 4 infrared lights. As such, it is possible to calibrate this device using normal camera calibration ...
  • A Framework for Performance Evaluation of Model-Based Optical Trackers 

    Smit, Ferdi A.; Liere, Robert van (The Eurographics Association, 2008)
    We describe a software framework to evaluate the performance of model-based optical trackers in virtual environments. The framework can be used to evaluate and compare the performance of different trackers under various ...
  • Supervision of 3D Multimodal Rendering for Protein-protein Virtual Docking 

    Bouyer, Guillaume; Bourdot, Patrick (The Eurographics Association, 2008)
    Protein-Protein docking is a recent practice in biological research which involves using 3D models of proteins to predict the structure of complexes formed by these proteins. Currently, the most common methods used for ...
  • Real-time Color Ball Tracking for Augmented Reality 

    Sýkora, Daniel; Sedlácek, David; Riege, Kai (The Eurographics Association, 2008)
    In this paper, we introduce a light-weight and robust tracking technique based on color balls. The algorithm builds on a variant of randomized Hough transform and is optimized for a use in real-time applications like on ...
  • A View Management Method for Mobile Mixed Reality Systems 

    Shibata, Fumihisa; Nakamoto, Hiroyuki; Sasaki, Ryoichi; Kimura, Asako; Tamura, Hideyuki (The Eurographics Association, 2008)
