    • Visuo-Haptic Redirected Walking Using Handrail 

      Matsumoto, Keigo; Narumi, Takuji; Yanase, Yohei; Ban, Yuki; Tanikawa, Tomohiro; Hirose, Michitaka (The Eurographics Association, 2018)
      A novel use of virtual reality (VR) was demonstrated. It enables a user to feel walking a straight virtual corridor while touching straight handrails, although the user walks while gripping circular handrails within a ...

    • User Evaluation of Visuo-Haptic Collocation System 

      Cha, B.; Bae, Y.; Choi, W.; Ryu, J. (The Eurographics Association, 2018)
      In the encounter-type haptic display systems, visuo-haptic collocation is essential because a poorly collocated pair of virtual and real objects may hinder natural interaction. This poster presents user evaluation results ...

    • Study of Human Behavioral Characteristics: Using Virtual Reality to Analyze Behavior of Following Moving Objects 

      Yonezawa, Kazuya; Segawa, Eigo; Tanaka, Ryuta (The Eurographics Association, 2018)
      It is crucial to model the physical world for simulation in which various phenomena are represented on a computer. In the case of simulation involving human actions, it is necessary to model not only physical phenomena but ...

    • Contribution to Ownership and Agency When Controlling a Mobile Robot 

      Hua, Junjie; Furukawa, Masahiro; Maeda, Taro (The Eurographics Association, 2018)
      Out-of-body experience shows that body ownership can be built through illusory visual-tactile correlation when man observes avatar from its back.On the other hand, ownership and agency are usually thought to be negative ...

    • Effect of an Encounter-Type Haptic Device on Forceps Position Reproducibility in Laparoscopic Tracking Training 

      Morishima, Akinobu; Terashima, Akihiro; Obama, Kazutaka; Sakai, Yoshiharu; Maeda, Taro; Ando, Hideyuki (The Eurographics Association, 2018)
      This paper describes an improvement to our previously proposed laparoscopic training system that was designed to improve surgical skill transmission by allowing surgical trainees to replicate the movements of skilled ...

    • Interactive Visual Exploration of Line Clusters 

      Kanzler, Mathias; Westermann, Rüdiger (The Eurographics Association, 2018)
      We propose a visualization approach to interactively explore the structure of clusters of lines in 3D space. We introduce cluster consistency fields to indicate the local consistency of the lines in a cluster depending on ...

    • Web-based Volume Rendering using Progressive Importance-based Data Transfer 

      Mwalongo, Finian; Krone, Michael; Reina, Guido; Ertl, Thomas (The Eurographics Association, 2018)
      WebGL 2.0 makes it possible to implement efficient volume rendering that runs in browsers using 3D textures and complex fragment shaders. However, a typical bottleneck for web-based volume rendering is the size of the ...

    • Painterly Rendering using Limited Paint Color Palettes 

      Lindemeier, Thomas; Gülzow, J. Marvin; Deussen, Oliver (The Eurographics Association, 2018)
      We present a painterly rendering method for digital painting systems as well as visual feedback based painting machines that automatically extracts color palettes from images and computes mixture recipes for these from a ...

    • Clustering for Stacked Edge Splatting 

      Abdelaal, Moataz; Hlawatsch, Marcel; Burch, Michael; Weiskopf, Daniel (The Eurographics Association, 2018)
      We present a time-scalable approach for visualizing dynamic graphs. By adopting bipartite graph layouts known from parallel edge splatting, individual graphs are horizontally stacked by drawing partial edges, leading to ...

    • Correlated Point Sampling for Geospatial Scalar Field Visualization 

      Roveri, Riccardo; Lehmann, Dirk J.; Gross, Markus; Günther, Tobias (The Eurographics Association, 2018)
      Multi-variate visualizations of geospatial data often use combinations of different visual cues, such as color and texture. For textures, different point distributions (blue noise, regular grids, etc.) can encode nominal ...

    • Identifying Similar Eye Movement Patterns with t-SNE 

      Burch, Michael (The Eurographics Association, 2018)
      In this paper we describe an approach based on the t-distributed stochastic neighbor embedding (t-SNE) focusing on projecting high-dimensional eye movement data to two dimensions. The lower-dimensional data is then represented ...

    • Efficient Subsurface Scattering Simulation for Time-of-Flight Sensors 

      Bulczak, David; Kolb, Andreas (The Eurographics Association, 2018)
      Today, amplitude modulated continuouswave (AMCW) Time-of-Flight (ToF) range cameras are ubiquitous devices that are employed in many fields of application, such as robotics, automotive industry, and home entertainment. ...

    • Compressed Bounding Volume Hierarchies for Efficient Ray Tracing of Disperse Hair 

      Martinek, Magdalena; Stamminger, Marc; Binder, Nikolaus; Keller, Alexander (The Eurographics Association, 2018)
      Ray traced human hair is becoming more and more ubiquitous in photorealistic image synthesis. Despite hierarchical data structures for accelerated ray tracing, performance suffers from the bad separability inherent with ...

    • Fast and Dynamic Construction of Bounding Volume Hierarchies Based on Loose Octrees 

      Gu, Feng; Jendersie, Johannes; Grosch, Thorsten (The Eurographics Association, 2018)
      Many fast methods for constructing BVHs on the GPU only use the centroids of primitive bounding boxes and ignore the actual spatial extent of each primitive. We present a fast new way and a memory-efficient implementation ...

    • Hierarchical Additive Poisson Disk Sampling 

      Dieckmann, Alexander; Klein, Reinhard (The Eurographics Association, 2018)
      Generating samples of point clouds and meshes with blue noise characteristics is desirable for many applications in rendering and geometry processing. Working with laser-scanned or lidar point clouds, we usually find region ...
