Increased performance is the key reason for developing software with virtual teams but the research efforts to date are limited. Difficulties for a formal, generic approach are multiplied by the significant differences between how small and large software organizations react to changing operational conditions and act to increase performance. The aim of the paper is to provide the guidelines on ...

This document presents the works carried out to ensure the immersion of a multiagent system in a virtual environment. The researches undertaken within the framework of this work have been allowed the development of tools dedicated to the simulation and th study of factory area, which are generally in perpetual evolution. This set of tools makes it possible to study various flows circulating on ...

Systems of distributed processors connected by a physical network may have a virtual structure imposed on them to facilitate parallel cooperative system actions. This paper describes the Multiple Virtual Rings organization which is an instance of this approach. System processors are partitioned into groups, structured as virtual rings, which operate in parallel to accumulate local information a...

The virtual learning community is an important application pattern of E-Learning. It emphasizes the cooperation of the members in the community, the members would like to share their learning resources, to exchange their experience and complete the study task together. This instructional mode has already been proved as an effective way to improve the quality and efficiency of instruction. At th...

We explore the applications of shallow-depth three-dimensional interaction on a touch-sensitive tabletop display. To guide this exploration, we chose the particular application of a virtual, simulated sandtray, such as those used in certain kinds of play therapy. This sandtray program is developed and evaluated in cooperation with several experts in sandtray therapy. The usefulness of a virtual...

We consider multiagent systems whose agents compete for resources using strategies with adaptable preferences. Diversity of initial preferences of strategies is introduced by randomly assigning virtual points to the strategies of each agent. When diversity increases, the successive appearance of scaling, kinetic sampling and waiting mechanisms shows that agent cooperation becomes increasingly i...

This paper presents actors in behavioral animation as being reactive autonomous agents in a virtual environment. The principles underlying the proposed model are cognition, emergence, situatedness, recursion and cooperation. Also the model is based on a cognitive architecture where both controlled and automatic procedures coexist. An animated sequence of a navigation scene is generated by a pro...

In the ICS, WUT a platform for simulation of cooperation of physical and virtual mobile agents is under development. The paper describes the motivation of the research, an organization of the platform, a model of agent, and the principles of design of the platform. Several experimental simulations are briefly described.

Distributing mixed realities in learning environments will open up new possibilities of local and distant cooperation in teaching and learning processes. Some requirements from the new vocational learning field mechatronics will be presented and our approach to meet them in a European Project, DERIVE-Distributed Real and Virtual Learning Environment, is shown.
