This paper presents novel software techniques for binocular eye tracking within Virtual Reality and discusses their application to aircraft inspection training. The aesthetic appearance of the environment is driven by standard graphical techniques ...

Rigid body orientation can be determined without the aid of a generated source using nine-axis MARG (Magnetic field, Angular Rate, and Gravity) sensor unit containing three orthogonally mounted angular rate sensors, three orthogonal linear ...

Augmented Reality (AR) can hardly be called uncharted territory. Much research in this area revealed solutions to the three most prominent challenges of AR: accurate camera state retrieval, resolving occlusions between real and virtual objects and ...

To support real-time natural interaction in the Collaborative Virtual Environment (CVE) with limited network bandwidth and computer processing power, the development of an efficient interaction management mechanism is a key issue. In this paper, we ...

This paper describes an object-oriented abstraction for the problem of awareness management in Collaborative Virtual Environments (CVEs). The described abstraction allows for different types of awareness information and awareness management policies to ...

Recently we have built a VR(Virtual Reality) theater in Kyongju, Korea. It combines the advantages of VR and IMAX theater. The VR theater can be characterized by a single shared screen and by multiple inputs from several hundreds of people. In this case,...

This article describes OpenTracker, an open software architecture that provides a framework for the different tasks involved in tracking input devices and processing multi-modal input data in virtual environments and augmented reality application. The ...

The Virtual-Reality Peripheral Network (VRPN) system provides a device-independent and network-transparent interface to virtual-reality peripherals. VRPN's application of factoring by function and of layering in the context of devices produces an ...

In this paper, we present a set of tools and techniques for visualization of and interaction with historical data. First, we briefly describe the data acquisition and preparation. Afterwards, we discuss in detail the interaction approaches for ...

The use of physics is a way to improve realism in Virtual Reality. In order to calculate virtual objects movement in a real-time physically based simulation, you have to solve ODE (Ordinary Differential Equations) relative to time. This solution has to ...

Multi-resolution techniques enhance the ability of graphics and visual systems to overcome limitations in time, space and transmission costs. Numerous techniques have been presented which concentrate on creating level of detail models for static meshes. ...

In this paper, we address the problem of shadow computation for large environments including thousands of dynamic objects. The method we propose is based on the assumption that the environment is 2.5D, which is often the case for virtual cities, thus ...

We introduce an idea and some preliminary results for a new projector-based approach to re-creating real and imagined sites. Our goal is to achieve re-creations that are both visually and spatially realistic, providing a small number of relatively ...

We are currently developing an immersive virtual environment display for research into the rehabilitation of balance disorders, called the Balance NAVE (BNAVE). Using this system, the therapist can create varying degrees of sensory conflict and ...

Teleoperation requires both wide vision to recognize a whole workspace and fine vision to recognize the precise structure of objects which an operator wants to see. In order to achieve high operational efficiency in teleoperation, we have developed the ...

VR has been explored as an artistic medium from its early beginnings in the last century. It has drawn off various other forms, be these theatre or the panorama. What are the current aesthetics of VR? How has content matured, engaged and created a new ...

Virtual reality researchers and artists will discuss the use of virtual reality as a creative and presentation medium. Museums, galleries, libraries, theatres, research entres, theme parks make varied use of VR. VR is no longer gee whiz, strong content, ...

For supporting real-time interaction in distributed virtual environments (DVEs), it is common to replicate virtual world data at clients from the server. For efficient replication, two schemes are used together in general - prioritized transfer of ...

Shared sense of a virtual world is often enhanced by replicating the information at each user's site since replication provides acceptable interactive performance, especially when users are geographically distributed over large networks like the ...

Although there are a few methods proposed for predicting 3D motion, most of these methods are primarily designed for predicting the motion of specific objects, by assuming certain object motion behaviors. We notice that in desktop distributed 3D ...

In this paper, we introduce a new style of visualization called Situational Visualization, in which the user of a robust, mobile visualization system uses mobile computing resources to enhance the experience and understanding of the surrounding world. ...

Real-time visualization of particle traces in virtual environments can aid in the exploration and analysis of complex three dimensional vector fields. This paper introduces a scalable method suitable for the interactive visualization of large time-...

A relevant issue for any Virtual Environment (VE) is the navigational support provided to users who are exploring it. Semitransparency is sometimes exploited as a means to see through occluding surfaces with the aim of improving user navigation ...

A sketching system for spline-based free-form surfaces on the Responsive Workbench is presented. We propose 3D tools for curve drawing and deformation techniques for curves and surfaces, adapted to the needs of designers. The user directly draws curves ...

Compared to conventional interfaces, Virtual reality (VR) interfaces contain a richer variety and more complex types of objects, behaviors, interactions and communications. Therefore, designers of VR interfaces face significant conceptual and ...

In this paper, we develop concepts for presenting interactive content in form of a slideshow in a virtual environment, similar to conventional desktop presentation software. We demonstrate how traditional content like text and images can be integrated ...
