An Approach to Interaction Interoperability for Distributed Virtual Environments
(The Eurographics Association, 2008)
We present a preliminary framework for interaction interoperability in Distributed Virtual Environments (DVEs). The goal is to allow each user to use a different input devices and interaction techniques and yet collaborate ...
Exploring Unsteady Flows by Parallel Extraction of Property-enhanced Pathlines and Interactive Post-filtering
(The Eurographics Association, 2008)
In this work a new approach of the visualization of unsteady high-resolution flow data in a network processing chain using property-enhanced traced particles or pathlines is presented. This approach allows to select subsets ...
Drawing the Gaps: Graphical Methods for Representing Geospatial and Temporal Uncertainty with Cultural Artifacts
(The Eurographics Association, 2008)
Modern visualization tools can present geographic information system (GIS) data as a 3D rendering, facilitating a user's understanding of the geospatial relationships between terrain and cultural features. While this ...
A User Guidance Approach for Passive Haptic Environments
(The Eurographics Association, 2008)
Traveling through virtual environments (VEs) by means of real walking is a challenging task since usually the size of the virtual world exceeds the size of the tracked interaction space. Redirected walking is one concept ...
Intuitive Navigation in Virtual Environments
(The Eurographics Association, 2008)
We present several novel ways of interaction and navigation in virtual worlds. Using the optical tracking system of our four-sided Definitely Affordable Virtual Environment (DAVE), we designed and implemented navigation ...
Effects of Platform (Immersive versus Non-immersive) on Usability and Enjoyment of a Virtual Learning Environment for Deaf and Hearing Children
(The Eurographics Association, 2008)
We report a user study focusing on the effects of platform (immersive, non-immersive) on usability and enjoyment of a deafaccessible game for K-5 math and science education. The study highlighted hearing status and gender ...
Visible Portion Estimation of Moving Target Objects for Networked Wearable Augmented Reality
(The Eurographics Association, 2008)
This paper describes a new visible portion estimation method of moving target object for networked wearable augmented reality (AR) system. In annotation overlay applications using AR systems, it is important to improve ...
Usability Evaluation in Virtual Reality: A User Study Comparing Three Different Setups
(The Eurographics Association, 2008)
We describe a user study comparing a low cost VR system using a Head-Mounted-Display (HMD) to a desktop and another setup where the image is projected on a screen. Eighteen participants played the same game in the three ...
A Proposal for a Procedural Terrain Modelling Framework
(The Eurographics Association, 2008)
Manual game content creation is an increasingly laborious task; with each advance in graphics hardware, a higher level of fidelity and detail is achievable and, therefore, expected. Although numerous automatic (e.g. ...
Improvement Rendering of Web3D Using the Shading Language
(The Eurographics Association, 2008)
Many Web3D systems for managing 3DCG in the contents of HTML pages use fixed shaders for graphics API for real-time 3DCG rendering, so it is difficult to simulate the global illumination. We propose a solution to the problem ...
