This paper presents a novel method of collaborative problem solving for intelligent agents in virtual environments. We describe a planner for STRIPS-like domains enhanced by techniques of "delegated computing". Instead of having one central planner with co ...
We are developing a Virtual Reality based training system for micromanipulation in collaboration with the National University Hospital in Singapore. While conventional approaches judge a virtual environment by its resemblance to the real environment, we us ...
The new breed of Personal Digital Assistants (PDA) and mobile phones have enough computing power to display 3D graphics. These new mobile devices (handhelds) have some other interesting communication and interaction possibilities as well. In this paper we ...
In the past decade, networked virtual environments (NVEs) have been an increasingly active area of research, with the first commercial systems emerging recently. Graphical and behavioral representation of users within such systems is a particularly importa ...
This paper presents an efficient and robust technique for generating global motion paths for a human model in virtual environments. Initially, a scene is discretized using raster hardware to generate an environment map. An obstacle-free cell path sub-optim ...
This paper discusses the main issues for creating interactive virtual environments with virtual humans emphasizing the following aspects: creation of virtual humans, gestures, interaction with objects, multimodal communication ...
Human reaching in a 3D environment is an interesting matter of research due to its application to workplace or vehicle-interior design. We introduce a 3D environment where a virtual human performs reaching tasks over 3D objects in the world. This environme ...
Describes the haptic rendering of a virtual environment by drawing upon concepts developed in the area of teleoperation. A four-channel teleoperation architecture is shown to be an effective means of coordinating the control of a 3-DOF haptic interface wit ...
The virtual orchestra is a multimodal system architecture based on complex 3D sound environment processing and a compact user interface. The system architecture supports high-performance sound content for VR (virtual reality) applications, and the user con ...
We have designed a mobile -PDA-based- interface for real-time control of virtual characters in multiuser semi-immersive virtual environments - using a large rear-projection screen. The proof-of-concept implementation we present shows the potential of handh ...
