    • Low-Cost, Portable, Multi-Wall Virtual Reality 

      Miller, Samuel A.; Misch, Noah J.; Dalton, Aaron J. (The Eurographics Association, 2005)
      Virtual reality systems make compelling outreach displays, but some systems highly suitable for outreach, notably the CAVE, have design features that make using them for that purpose inconvenient. In the case of the CAVE, ...
    • Dynamic Bounding Volume Hierarchies for Occlusion Culling 

      Kovalcík, Vít; Tobola, Petr (The Eurographics Association, 2005)

      The use of Virtual Reality technology for the product engineering process in the automotive industry has a lot of potential in particular in the area of usability and reachability studies. We analyzed the manipulation ...
    • Näprä - Affordable Fingertip Tracking with Ultrasound 

      Reunanen, M.; Palovuori, K.; Ilmonen, T.; Mäkelä, W. (The Eurographics Association, 2005)
      In this paper we present Näprä, a novel tracking device suitable for fine motor interaction. The motivation for building the device was the need to track users' fingertips in an immersive free-hand drawing environment. ...
    • Augmented Reality Interaction for Semiautomatic Volume Classification 

      Río, A. del; Fischer, J.; Köbele, M.; Bartz, D.; Straßer, W. (The Eurographics Association, 2005)
      In the visualization of 3D medical data, the appropriateness of the achieved result is highly dependent on the application. Therefore, an intuitive interaction with the user is of utter importance in order to determine the ...
    • Virtual Pockets in Virtual Reality 

      Ilmonen, Tommi; Reunanen, Markku (The Eurographics Association, 2005)
      This paper presents the use of the virtual pocket user interface metaphor in virtual environments (VEs). Virtual pockets act like real-world pockets ó the user can put tools into pockets and select them with simple gestures. ...
    • Real-time Deformation of Detailed Geometry Based on Mappings to a Less Detailed Physical Simulation on the GPU 

      Mosegaard, J.; Sørensen, T. S. (The Eurographics Association, 2005)
      Modern graphics processing units (GPUs) can be effectively used to solve physical systems. To use the GPU optimally, the discretization of the physical system is often restricted to a regular grid. When grid values represent ...
    • Binaural Acoustics For CAVE-like Environments Without Headphones 

      Assenmacher, I.; Kuhlen, T.; Lentz, T. (The Eurographics Association, 2005)
      The human auditory system, in contrast to the human visual system, can perceive input from all directions and has no limited field of view. As such, it provides valuable cues for navigation and orientation in virtual ...
