This paper presents the Projector-based, Desktop, Reach-In Virtual Environment, or PDRIVE. A PDRIVE user "reaches in" to the virtual environment, which he views through a mirror. Stereo images are generated by two standard, off-the-shelf DLP projectors, ...

We describe the Spinnstube®, a new projection-based Augmented Reality display system for collaborative work environments. By simply attaching the system to a desk, real objects are augmented with virtual objects by using a half-silvered mirror. The ...

Virtual Reality (VR) has become a useful tool in psychological therapy, rehabilitation, and basic research. It provides the therapist or scientist with high ecological validity and complete control over multimodal stimuli and the virtual environment. To ...

Sharing one large screen projection display, such as the Virtual Workbench, with multiple users can cause distortions in viewing and interaction, as the users perceive a sheared and moving space. Generally, object rotation in non-orthogonal, sheared ...

We describe a user study comparing a two-handed controller-based input device to a two-handed tracking solution, both offering the control space of six degrees of freedom to each hand. For benchmarking the different input modalities we implemented a set ...

Widgets are often used to perform control tasks in three-dimensional (3D) virtual environments (VEs). Spatial interactions through widgets require precise 3D manipulations, and several design aspects of VEs contribute to the ease, accuracy, and speed ...

In this paper we present a novel approach of the magic lens user interface metaphor for large-scale projectorbased displays. We altered a standard polarization-based passive stereo projection setup and employed a standard LCD panel as a purely optical, ...

With rising data sizes and growing complexity, the results of modern numerical simulations are increasingly dif- ficult to understand. Thus, using Virtual Reality methodology for an interactive analysis of such data gains more and more importance. ...

In this paper, we firstly propose a partial-sampling scheme to measure the intensity transfer function of a projector. Secondly, we implement the computation of luminance surface by rendering a texture rectangle on GPU. Thirdly, we generate an unified ...

Stereo displays suffer from crosstalk, an effect that reduces or even inhibits the viewer's ability to correctly fuse stereoscopic images. In this paper, three extensions for improved software crosstalk reduction are introduced. First, we propose a ...

This article addresses the question of integrating multimodal rendering in Virtual Reality applications. It exposes first the interest of multimedia intelligent systems to improve human activity in Virtual Environments. Then it details the conception of ...

Most dead reckoning implementations are based on DIS' specifications and only use a single prediction model during the whole simulation. However, several studies manage to improve dead reckoning's performance by defining prediction model selection ...

One of the main problems of monoscopic video see-through augmented reality (AR) is the lack of reliable depth information. This makes it difficult to correctly represent complex spatial interactions between real and virtual objects, e.g., when rendering ...
