    • 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 ...
    • 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, ...
    • 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 ...
    • Enhanced Hand Manipulation for Efficient and Precise Positioning and Release 

      Osawa, N. (The Eurographics Association, 2005)
      Direct manipulation by hand is important in that it allows users to manipulate 3D virtual objects easily in an immersive virtual reality environment. Although direct hand manipulation is easy to understand and easy to use ...
    • Evaluation of Collaborative Construction in Mixed Reality 

      Boschker, Breght R.; Mulder, Jurriaan D. (The Eurographics Association, 2005)
      Collaborative virtual and augmented reality are an active area of research and many systems supporting collaboration have been presented. Just like there are many different systems for VR and AR, there are many different ...
    • Applications of Augmented Reality for Maintenance Training 

      Weng, Dongdong; Wang, Yongtian; Liu, Yue (The Eurographics Association, 2005)
      An Augmented Reality system that is designed for maintenance training is introduced. The proposed system adopts a projector to display the augmented video of the components to be repaired. With the augmented video, students ...
    • 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 ...
    • 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, ...
    • 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, ...
