Interaction in conversational interfaces strongly relies on the system’s capability to interpret the user’s references to objects via deictic expressions. Deictic gestures, es...

Access control is an important aspect of shared virtual environments. Resource access may not only depend on prior authorization, but also on context of usage such as distance or ...

In this paper, we report the results of a pilot study designed to evaluate the impact of signs as navigation aids in virtual worlds. Test subjects were divided into three groups (...
This paper describes the influence of visual stimulation on the tactual sense in a mixed-reality environment; i.e., how a tactual impression of a real object is affected by seeing...
This paper presents a complete framework for creating a speechenabled avatar from a single image of a person. Our approach uses a generic facial motion model which represents defo...
We describe a simple load-measure-model method for analyzing the scalability of Distributed Virtual Environments (DVEs). We use a load simulator and three metrics to measure a DVE...
Registration errors between the physical world and computergenerated objects are a central problem in Augmented Reality (AR) systems. Some existing AR systems have demonstrated ho...
Most projector-based immersive displays have numerous problems relating to complexity, space, and cost. We present a technique for rendering perspectively correct images using a c...
Multi-frame rate rendering is a parallel rendering technique that renders interactive parts of the scene on one graphics card while the rest of the scene is rendered asynchronousl...

In this paper we introduce a virtual locomotion system that allows navigation within any large-scale virtual environment (VE) by real walking. In contrast to [5] we have developed...
