    • PDRIVE: The Projector-based, Desktop, Reach-In Virtual Environment 

      Haan, Gerwin de; Griffith, Eric J.; Koutek, Michal; Post, Frits H. (The Eurographics Association, 2007)
      This paper presents the Projector-based, Desktop, Reach-In Virtual Environment, or PDRIVE. A PDRIVE user reaches in to the virtual environment, which he views through a mirror. Stereo images are generated by two standard, ...

    • Visual Consistency in Rotational Manipulation Tasks in Sheared-Perceived Virtual Environments 

      Koutek, Michal; Molenaar, Rene; Haan, Gerwin de; Post, Frits H. (The Eurographics Association, 2007)
      Sharing one large screen projection display, such as the Virtual Workbench, with multiple users can cause distortions in viewing and interaction, as the users perceive a sheared and moving space. Generally, object rotation ...

    • A Comparison of Tracking- and Controller-Based Input for Complex Bimanual Interaction in Virtual Environments 

      Kunert, Andre; Kulik, Alexander; Huckauf, Anke; Froehlich, Bernd (The Eurographics Association, 2007)
      We describe a user study comparing a two-handed controller-based input device to a two-handed tracking solution, both offering the control space of six degrees of freedom to each hand. For benchmarking the different input ...

    • Widget Manipulation Revisited: a Case Study in Modeling Interactions Between Experimental Conditions 

      Martens, Jean-Bernard; Kok, Arjan; Liere, Robert van (The Eurographics Association, 2007)
      Widgets are often used to perform control tasks in three-dimensional (3D) virtual environments (VEs). Spatial interactions through widgets require precise 3D manipulations, and several design aspects of VEs contribute to ...

    • Adaptive Classifier System-Based Dead Reckoning 

      Torki, Samir; Torguet, Patrice; Sanza, Cedric (The Eurographics Association, 2007)
      Most dead reckoning implementations are based on DIS specifications and only use a single prediction model during the whole simulation. However, several studies manage to improve dead reckoning s performance by defining ...

    • Supervision of Task-Oriented Multimodal Rendering for VR Applications 

      Bouyer, Guillaume; Bourdot, Patrick; Ammi, Mehdi (The Eurographics Association, 2007)
      This article addresses the question of integrating multimodal rendering in Virtual Reality applications. It exposes first the interest of multimedia intelligent systems to improve human activity in Virtual Environments. ...

    • Using Time-of-Flight Range Data for Occlusion Handling in Augmented Reality 

      Fischer, Jan; Huhle, Benjamin; Schilling, Andreas (The Eurographics Association, 2007)
      One of the main problems of monoscopic video see-through augmented reality (AR) is the lack of reliable depth information. This makes it difficult to correctly represent complex spatial interactions between real and virtual ...

    • Optical Magic Lenses and Polarization-Based Interaction Techniques 

      Waldner, Manuela; Kalkusch, Michael; Schmalstieg, Dieter (The Eurographics Association, 2007)
      In this paper we present a novel approach of the magic lens user interface metaphor for large-scale projectorbased displays. We altered a standard polarization-based passive stereo projection setup and employed a standard ...

    • High Ecological Validity and Accurate Stimulus Control in VR-based Psychological Experiments 

      Wolter, Marc; Armbruester, Claudia; Valvoda, Jakob T.; Kuhlen, Torsten (The Eurographics Association, 2007)
      Virtual Reality (VR) has become a useful tool in psychological therapy, rehabilitation, and basic research. It provides the therapist or scientist with high ecological validity and complete control over multimodal stimuli ...

    • Three Extensions to Subtractive Crosstalk Reduction 

      Smit, Ferdi A.; Liere, Robert van; Froehlich, Bernd (The Eurographics Association, 2007)
      Stereo displays suffer from crosstalk, an effect that reduces or even inhibits the viewer s ability to correctly fuse stereoscopic images. In this paper, three extensions for improved software crosstalk reduction are ...

    • A GPU-Based Framework of Photometric Uniformity for Multi-Projector Tiled Display 

      Yuan, Guodong; Qin, Kaihuai (The Eurographics Association, 2007)
      In this paper, we firstly propose a partial-sampling scheme to measure the intensity transfer function of a projector. Secondly, we implement the computation of luminance surface by rendering a texture rectangle on GPU. ...

    • Spinnstube: A Seated Augmented Reality Display System 

      Wind, Jürgen; Riege, Kai; Bogen, Manfred (The Eurographics Association, 2007)
      We describe the Spinnstube, a new projection-based Augmented Reality display system for collaborative work environments. By simply attaching the system to a desk, real objects are augmented with virtual objects by using a ...

    • Interactive Exploration of Large Data in Hybrid Visualization Environments 

      Schirski, Marc; Bischof, Christian; Kuhlen, Torsten (The Eurographics Association, 2007)
      With rising data sizes and growing complexity, the results of modern numerical simulations are increasingly dif- ficult to understand. Thus, using Virtual Reality methodology for an interactive analysis of such data gains ...
