Language Learning in Virtual Environments: Bobo and Apples
(The Eurographics Association, 2005)
Bobo and Apples is one of the prototype games within SAME4KIDS (Speech-based,Animated, Multilingual,Educational games for Kids, http://same4kids.sourceforge.net/ ), a multi-language and multi-purpose games project for ...
Distributed Software-Based Volume Visualization in a Virtual Environment
(The Eurographics Association, 2005)
In this paper we present our integration of volume rendering into virtual reality, combining a fast and flexible software implementation of direct volume rendering with the intuitive manipulation and navigation techniques ...
Optical Tracking and Calibration of Tangible Interaction Devices
(The Eurographics Association, 2005)
In this paper, a novel optical tracking and object calibration system is presented for the recognition and pose estimation of tangible interaction devices for virtual and augmented reality systems. The calibration system ...
Modeling of Trees with 3D Gestures and Growth Simulation
(The Eurographics Association, 2005)
We propose a modeling system that enables users to create tree models with 3D gesture input. It generates tree models by using growth simulation based on the trunk or silhouette shapes of trees given by user gestures. The ...
Low-Cost, Portable, Multi-Wall Virtual Reality
(The Eurographics Association, 2005)
Virtual reality systems make compelling outreach displays, but some systems highly suitable for outreach, notably the CAVE, have design features that make using them for that purpose inconvenient. In the case of the CAVE, ...
Dynamic Bounding Volume Hierarchies for Occlusion Culling
(The Eurographics Association, 2005)
We present an algorithm for rendering complex scenes using occlusion queries to resolve visibility. To organize objects in the scene, the algorithm uses a ternary tree which is dynamically modified according to the current ...
Pseudo-Physical Interaction with a Virtual Car Interior in Immersive Environments
(The Eurographics Association, 2005)
The use of Virtual Reality technology for the product engineering process in the automotive industry has a lot of potential in particular in the area of usability and reachability studies. We analyzed the manipulation ...
Näprä - Affordable Fingertip Tracking with Ultrasound
(The Eurographics Association, 2005)
In this paper we present Näprä, a novel tracking device suitable for fine motor interaction. The motivation for building the device was the need to track users' fingertips in an immersive free-hand drawing environment. ...
Augmented Reality Interaction for Semiautomatic Volume Classification
(The Eurographics Association, 2005)
In the visualization of 3D medical data, the appropriateness of the achieved result is highly dependent on the application. Therefore, an intuitive interaction with the user is of utter importance in order to determine the ...
Virtual Pockets in Virtual Reality
(The Eurographics Association, 2005)
This paper presents the use of the virtual pocket user interface metaphor in virtual environments (VEs). Virtual pockets act like real-world pockets ó the user can put tools into pockets and select them with simple gestures. ...
