    • Background Motion, Clutter, and the Impact on Virtual Object Motion Perception in Augmented Reality 

      Ferrer, Vicente; Yang, Yifan; Perdomo, Alex; Quarles, John (The Eurographics Association, 2013)
      Background motion and visual clutter are present in almost all augmented reality applications. However, there is minimal prior work that has investigated the effects that background motion and clutter (e.g., a busy city ...
    • Evaluation of Surround-View and Self-Rotation in the OCTAVIS VR-System 

      Dyck, Eugen; Pfeiffer, Thies; Botsch, Mario (The Eurographics Association, 2013)
      In this paper we evaluate spatial presence and orientation in the OCTAVIS system, a novel virtual reality platform aimed at training and rehabilitation of visual-spatial cognitive abilities. It consists of eight touch-screen ...
    • Exploring Distant Objects with Augmented Reality 

      Tatzgern, Markus; Grasset, Raphael; Veas, Eduardo; Kalkofen, Denis; Seichter, Hartmut; Schmalstieg, Dieter (The Eurographics Association, 2013)
      Augmented reality (AR) enables users to retrieve additional information about the real world objects and locations. Exploring such location-based information in AR requires physical movement to different viewpoints, which ...
    • Free-form Implicit Haptic Rendering 

      Moustakas, Konstantinos (The Eurographics Association, 2013)
      This paper presents a framework for haptic rendering in virtual environments based on distance maps over implicit support plane mappings. Initially, a rigid 3D object is modelled using support plane mappings so as to ...
    • The Impact of Altered Gravitation on Performance and Workload of Augmented Reality Hand-Eye-Coordination: Inside vs. Outside of Human Body Frame of Reference 

      Markov-Vetter, Daniela; Zander, Vanja; Latsch, Joachim; Staadt, Oliver (The Eurographics Association, 2013)
      We investigated new interface technologies to ease astronaut0s work under altered gravity. By bridging the gap between the physical reality and digital information, Augmented Reality keeps the focus on the task to fulfill. ...
    • ''It''+''I'': Virtual Embodiments as Hybrid Experiences 

      Giraud, Tom; Paljic, Alexis; Leroy, Laure (The Eurographics Association, 2013)
      A dichotomy exists in the way virtual embodiments are currently studied: embodied entities are considered by conversational approaches as other selves whereas avatar approaches study them as users' hosts. Virtual reality ...
    • LightSkin: Real-Time Global Illumination for Virtual and Mixed Reality 

      Lensing, Philipp; Broll, Wolfgang (The Eurographics Association, 2013)
      Synthesizing global illumination effects is a vast field of research for both offline and real-time rendering. While the most important goals for offline rendering are realism and physical correctness, real-time rendering ...
    • Methodology for Immersive Emotional Assessment of Virtual Product Design by Customers 

      Katicic, Jurica; Häfner, Polina; Ovtcharova, Jivka (The Eurographics Association, 2013)
      This paper presents a novel, integrated methodology for customer-centered emotional assessment of future products during the early conceptual design stages. This methodology integrates the technologies of Virtual Reality ...
    • Personalized Animatable Avatars from Depth Data 

      Mashalkar, Jai; Bagwe, Niket; Chaudhuri, Parag (The Eurographics Association, 2013)
      Abstract We present a method to create virtual character models of real users from noisy depth data. We use a combination of four depth sensors to capture a point cloud model of the person. Direct meshing of this data often ...
    • Ray-Traced Collision Detection: Interpenetration Control and Multi-GPU Performance 

      Lehericey, Francois; Gouranton, Valérie; Arnaldi, Bruno (The Eurographics Association, 2013)
      We proposed in [LGA13] an iterative ray-traced collision detection algorithm (IRTCD) that exploits spatial and temporal coherency and proved to be computationally efficient but at the price of some geometrical approximations ...
    • Semantic Modelling of Interactive 3D Content 

      Flotynski, Jakub; Walczak, Krzysztof (The Eurographics Association, 2013)
      Interactive three-dimensional content is the primary element of virtual reality (VR) and augmented reality (AR) systems. The increasing complexity and the use of VR/AR systems in various application domains requires efficient ...
    • Towards Enabling More Effective Locomotion in VR Using a Wheelchair-based Motion Platform 

      Fiore, Loren Puchalla; Coben, Ella; Merritt, Samantha; Liu, Peng; Interrante, Victoria (The Eurographics Association, 2013)
      This paper addresses two questions relevant to the design of effective locomotion methods for VR using a novel wheelchair motion simulation interface. First, we investigate the extent to which people's ability to keep track ...
    • Visual Attention to Wayfinding Aids in Virtual Environments 

      Bertrand, Jeffrey; Ebrahimi, Elham; Wachter, Aliceann; Luo, Jun; Babu, Sabarish V.; Duchowski, Andrew T.; Meehan, Nancy; Gramopadhye, Anand K. (The Eurographics Association, 2013)
      In an empirical evaluation, we examined participants' visual attention allocation to a dynamic wayfinding map in a complex simulation meant to educate medical practitioners in a hand hygiene protocol. Complex virtual ...
