    • Imperceptible Projection Blanking for Reliable Segmentation within Mixed Reality Applications 

      Kuechler, M.; Kunz, A. (The Eurographics Association, 2005)
      Applications that run in a projection-based mixed reality environment frequently require simultaneous image acquisition of the user by a camera. For later processing, very often a segmentation of the user s image is required, ...

    • IntenSelect: Using Dynamic Object Rating for Assisting 3D Object Selection 

      Haan, Gerwin de; Koutek, Michal; Post, Frits H. (The Eurographics Association, 2005)
      We present IntenSelect, a novel selection technique that dynamically assists the user in the selection of 3D objects in Virtual Environments. Ray-casting selection is commonly used, although it has limited accuracy and can ...

    • Interacting with Molecular Structures: User Performance versus System Complexity 

      Liere, R. van; Martens, J.-B. O. S.; Kok, A. J. F.; Tienen, M. H. A. V. van (The Eurographics Association, 2005)
      Effective interaction in a virtual environment requires that the user can adequately judge the spatial relationships between the objects in a 3D scene. In order to accomplish adequate depth perception, existing virtual ...

    • Language Learning in Virtual Environments: Bobo and Apples 

      Holmen, H.; Nielsen, F. (The Eurographics Association, 2005)
      Bobo and Apples is one of the prototype games within SAME4KIDS (Speech-based,Animated, Multilingual,Educational games for Kids, http://same4kids.sourceforge.net/ ), a multi-language and multi-purpose games project for ...

    • 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, ...

    • Modeling of Trees with 3D Gestures and Growth Simulation 

      Murakami, N.; Onishi, K.; Kitamura, Y.; Kishino, F. (The Eurographics Association, 2005)
      We propose a modeling system that enables users to create tree models with 3D gesture input. It generates tree models by using growth simulation based on the trunk or silhouette shapes of trees given by user gestures. The ...

    • 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. ...

    • Optical Tracking and Calibration of Tangible Interaction Devices 

      Rhijn, Arjen van; Mulder, Jurriaan D. (The Eurographics Association, 2005)
      In this paper, a novel optical tracking and object calibration system is presented for the recognition and pose estimation of tangible interaction devices for virtual and augmented reality systems. The calibration system ...

    • Pseudo-Physical Interaction with a Virtual Car Interior in Immersive Environments 

      Moehring, Mathias; Froehlich, Bernd (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 ...

    • 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 ...

    • Reducing Fragmentation in Telecollaboration by Using IPT Interfaces 

      Roberts, D.; Al-Liabi, M.; Wolff, R.; Otto, O.; Al-Khalifah, A. (The Eurographics Association, 2005)
      Telecommunication systems, such as AccessGrid, allow collaboration across a distributed team. However, these systems typically introduce fragmentation into the view of the shared environment. Many have found that IPT systems ...

    • Running Large VR Applications on a PC Cluster: the FlowVR Experience 

      Allard, Jérémie; Ménier, Clément; Boyer, Edmond; Raffin, Bruno (The Eurographics Association, 2005)
      In this paper, we present how FlowVR enables the development of modular and high performance VR applications running on a PC cluster. FlowVR is a middleware we specifically developed targeting distributed interactive ...

    • Tangible 3D: Hand Gesture Interaction for Immersive 3D Modeling 

      Kim, Hyosun; Albuquerque, Georgia; Havemann, Sven; Fellner, Dieter W. (The Eurographics Association, 2005)
      Most of all interaction tasks relevant for a general three-dimensional virtual environment can be supported by 6DOF control and grab/select input. Obviously a very efficient method is direct manipulation with bare hands, ...
