    • Integrating Semantic Directional Relationships into Virtual Environments: A Meta-modelling Approach 

      Trinh, Thanh-Hai; Chevaillier, Pierre; Barange, M.; Soler, J.; Loor, P. De; Querrec, R. (The Eurographics Association, 2011)
      This study is concerned with semantic modelling of virtual environments (VEs). A semantic model of a VE provides an abstract and high level representation of main aspects of the environment: ontological structures, behaviours ...
    • Modeling the Effect of Force Feedback for 3D Steering Tasks 

      Liu, Lei; Liere, Robert van; Kruszynski, Krzysztof J. (The Eurographics Association, 2011)
      Path steering is an interaction task of how quickly one may navigate through a path. The steering law, proposed by Accot and Zhai [AZ97], is a predictive model which describes the time to accomplish a 2D steering task as ...
    • Short Paper: Acquisition and Management of Building Materials for VR Applications 

      Westner, Phil; Bues, Matthias (The Eurographics Association, 2011)
      This paper describes a workflow and system to digitize, manage and render large and fast changing sets of building materials, e.g. brick, concrete, ceramic tiles, for VR architectural visualization. We describe the use ...
    • Panoramic Video Techniques for Improving Presence in Virtual Environments 

      Dalvandi, Arefe; Riecke, Bernhard E.; Calvert, Tom (The Eurographics Association, 2011)
      Photo-realistic techniques that use sequences of images captured from a real environment can be used to create virtual environments (VEs). Unlike 3D modelling techniques, the required human work and computation are independent ...
    • Adapting Standard Video Codecs for Depth Streaming 

      Pece, Fabrizio; Kautz, Jan; Weyrich, Tim (The Eurographics Association, 2011)
      Cameras that can acquire a continuous stream of depth images are now commonly available, for instance the Microsoft Kinect. It may seem that one should be able to stream these depth videos using standard video codecs, such ...
    • The Impact of Viewing Stereoscopic Displays on the Visual System 

      Howarth, Peter A.; Underwood, P. J. (The Eurographics Association, 2011)
      The study examined the effects of varying the accommodation-convergence conflict created by stereoscopic displays which are now commonly used for the viewing of virtual environments, television and cinema. These displays ...
    • An Interdisciplinary VR-architecture for 3D Chatting with Non-verbal Communication 

      Gobron, Stephane; Ahn, Junghyun; Silvestre, Quentin; Thalmann, Daniel; Rank, Stefan; Skowron, Marcin; Paltoglou, Georgios; Thelwall, Michael (The Eurographics Association, 2011)
      The communication between avatar and agent has already been treated from different but specialized perspectives. In contrast, this paper gives a balanced view of every key architectural aspect: from text analysis to computer ...
    • Short Paper: Exploring the Object Relevance of a Gaze Animation Model 

      Oyekoya, Oyewole; Steed, Anthony; Pan, Xueni (The Eurographics Association, 2011)
      Models for animating the eyes of virtual characters often focus on making the face appear natural and believable. There has been relatively little work in computer graphics that investigates the relevance of the objects ...
    • Exploring Frictional Surface Properties for Haptic-Based Online Shopping 

      Bamarouf, Yasser A.; Smith, Shamus P. (The Eurographics Association, 2011)
      The sense of touch is important in our everyday lives and its absence makes it difficult to explore and manipulate everyday objects. Existing online shopping practice lacks the opportunity for physical evaluation, that ...
    • Novative Rendering and Physics Engines to Apprehend Special Relativity 

      Doat, Tony; Parizot, Etienne; Vézien, Jean-Marc (The Eurographics Association, 2011)
      Relativity, as introduced by Einstein, is regarded as one of the most important revolutions in the history of physics. Nevertheless, the observation of direct outcomes of this theory on mundane objects is impossible because ...
    • V3S, a Virtual Environment for Risk Management Training 

      Barot, Camille; Burkhardt, Jean-Marie; Lourdeaux, Domitile; Lenne, Dominique (The Eurographics Association, 2011)
      In high risk industries, risk management training has become a major issue. It requires not only to teach rules and procedures, but also to promote a real understanding of the risks that are at stake and to train learners ...
    • Short Paper: Comparing Virtual Trajectories Made in Slalom UsingWalking-In-Place and Joystick Techniques 

      Terziman, Léo; Marchal, Maud; Multon, Franck; Arnaldi, Bruno; Lécuyer, Anatole (The Eurographics Association, 2011)
      In this paper we analyze and compare the trajectories made in a Virtual Environment with two different navigation techniques. The first is a standard joystick technique and the second is the Walking-In-Place (WIP) technique. ...
    • Short Paper: View Dependent Rendering to Simple Parametric Display Surfaces 

      Harish, Pawan; Narayanan, P. J. (The Eurographics Association, 2011)
      Computer displays have remained flat and rectangular for the most part. In this paper, we explore parametric display surfaces, which are of arbitrary shape, but with a mapping to a 2D domain for each pixel. The display ...
    • User Centred Methods for Gathering VR Design Tool Requirements 

      Thalen, Jos P.; Voort, M. C. van der (The Eurographics Association, 2011)
      This paper addresses the use of VR to facilitate design tasks in the early stages of a product design process. A preliminary exploratory study, involving over thirty interviews amongst four industrial partners, revealed ...
    • Bimanual Haptic Simulator for Medical Training: System Architecture and Performance Measurements 

      Ullrich, Sebastian; Rausch, Dominik; Kuhlen, Torsten (The Eurographics Association, 2011)
      In this paper we present a simulator for two-handed haptic interaction. As an application example, we chose a medical scenario that requires simultaneous interaction with a hand and a needle on a simulated patient. The ...
    • Realistic Lighting Simulation for Interactive VR Applications 

      Löffler, Alexander; Marsalek, Lukas; Hoffmann, Hilko; Slusallek, Philipp (The Eurographics Association, 2011)
      In the field of aircraft design, interior illumination increasingly becomes an important design element. Different illumination scenarios inside an aircraft cabin are considered to influence the mood of air passengers, ...
