  • Hybrid Interfaces in VEs: Intent and Interaction 

    Haan, Gerwin de; Griffith, Eric J.; Koutek, Michal; Post, Frits H. (The Eurographics Association, 2006)
    Hybrid user interfaces (UIs) integrate well-known 2D user interface elements into the 3D virtual environment, and provide a familiar and portable interface across a variety of VR systems. However, their usability is often ...
  • GA based Adaptive Sampling for Image-based Walkthrough 

    Lee, Dong Hoon; Kim, Jong Ryul; Jung, Soon Ki (The Eurographics Association, 2006)
    This paper presents an adaptive sampling method for image-based walkthrough. Our goal is to select minimal sets from the initially dense sampled data set, while guaranteeing a visual correct view from any position in any ...
  • A New View Management Method for Wearable Augmented Reality Systems - Emphasizing the User-viewed Object and the Corresponding Annotation - 

    Tenmoku, R.; Kanbara, M.; Yokoya, N. (The Eurographics Association, 2006)
    This paper describes a new view management method for annotation overlay using augmented reality(AR) systems. The proposed method emphasizes the user-viewed object and the corresponding annotation in order to present links ...
  • Interactive Data Annotation in Virtual Environments 

    Assenmacher, I.; Hentschel, B.; Ni, C.; Kuhlen, T.; Bischof, C. (The Eurographics Association, 2006)
    Note-taking is an integral part of scientific data analysis. In particular, it is vital for explorative analysis, as the expression and transformation of ideas is a necessary precondition for gaining insight. However, in ...
  • Camera Setup Optimization for Optical Tracking in Virtual Environments 

    Cerfontaine, Philippe A.; Schirski, Marc; Bündgens, Daniel; Kuhlen, Torsten (The Eurographics Association, 2006)
    In this paper we present a method for finding the optimal camera alignment for a tracking system with multiple cameras, by specifying the volume that should be tracked and an initial camera setup. The approach we use is ...
  • Model-based Hybrid Tracking for Medical Augmented Reality 

    Fischer, Jan; Eichler, Michael; Bartz, Dirk; Straßer, Wolfgang (The Eurographics Association, 2006)
    Camera pose estimation is one of the most important, but also one of the most challenging tasks in augmented reality. Without a highly accurate estimation of the position and orientation of the digital video camera, it is ...
  • A Survey and Taxonomy of 3D Menu Techniques 

    Dachselt, R.; Hübner, A. (The Eurographics Association, 2006)
    A huge variety of interaction techniques was developed in the field of virtual and augmented reality. Whereas techniques for object selection, manipulation, travel, and wayfinding were covered in existing taxonomies quite ...
  • Friction surfaces: scaled ray-casting manipulation for interacting with 2D GUIs 

    Andujar, C.; Argelaguet, F. (The Eurographics Association, 2006)
    The accommodation of conventional 2D GUIs with Virtual Environments (VEs) can greatly enhance the possibilities of many VE applications. In this paper we present a variation of the well-known ray-casting technique for fast ...
  • A Multi Modal Table-Top 3D Modeling Tool in Augmented Environments 

    Novotny, Tom; Lindt, Irma; Broll, Wolfgang (The Eurographics Association, 2006)
    Even with today's highly sophisticated 3D modeling programs, creating, assembling and adapting 3D models is still a big challenge for inexperienced users. In this paper we present our approach of an intuitive table-top 3D ...
  • Measuring the Discernability of Virtual Objects in Conventional and Stylized Augmented Reality 

    Fischer, Jan; Cunningham, Douglas; Bartz, Dirk; Wallraven, Christian; Bülthoff, Heinrich; Straßer, Wolfgang (The Eurographics Association, 2006)
    In augmented reality, virtual graphical objects are overlaid over the real environment of the observer. Conventional augmented reality systems normally use standard real-time rendering methods for generating the graphical ...
  • GraphTracker: A Topology Projection Invariant Optical Tracker 

    Smit, F. A.; Rhijn, A. van; Liere, R. van (The Eurographics Association, 2006)
    In this paper, we describe a new optical tracking algorithm for pose estimation of interaction devices in virtual and augmented reality. Given a 3D model of the interaction device and a number of camera images, the primary ...
  • Fast Continuous Collision Detection among Deformable Models using Graphics Processors 

    Govindaraju, Naga K.; Kabul, Ilknur; Lin, Ming C.; Manocha, Dinesh (The Eurographics Association, 2006)
    We present an interactive algorithm to perform continuous collision detection between general deformable models using graphics processors (GPUs). We model the motion of each object in the environment as a continuous path ...
  • Wearable Mixed Reality System In Less Than 1 Pound 

    Peternier, Achille; Vexo, Frédéric; Thalmann, Daniel (The Eurographics Association, 2006)
    We have designed a wearable Mixed Reality (MR) framework which allows to real-time render game-like 3D scenes on see-through head-mounted displays (see through HMDs) and to localize the user position within a known internet ...
