Virtual Roommates” is a mapping between loosely linked spaces, that allows users to overlay multiple physical and virtual scenes and populate them with physical and/or virtual characters. As the name implies, the Virtual Roommates concept provides continuous ambient presence for multiple disparate groups, similar to people sharing living conditions, but without the boundaries of real space. Thi...

This paper presents a model describing Intelligent Information present in the Virtual Environment, as well as the Camera Control. We are interested in modeling Intelligent Virtual Environments, integrated with our Intelligent Camera control in order to provide information to be used in behavioural simulations. Our main goal is to be able to populate Virtual Environments with virtual agents endo...

Although context-dependent spike synchronization among populations of neurons has been experimentally observed, its functional role remains controversial. In this modeling study, we demonstrate that in a network of spiking neurons organized according to spike-timing-dependent plasticity, an increase in the degree of synchrony of a uniform input can cause transitions between memorized activity p...

A set of tools is presented within the theoretical framework of activity systems that is designed and developed to reify the communication acts of team members to support reflective learning. An evaluation tests the acceptability of the tools used within two multi-agent virtual reality simulations. We explore the affordance of the tools and issues around their acceptability in two experimental ...

Many modern virtual reality reconstructions of historical sites focus on buildings and artefacts, but often ignore the issue of portraying everyday life of the people who populated the reconstructed area. This is mainly due to high costs and complexity of populating such sites with virtual agents. Here we show how combining needs modelling and planning can help to automate the development of la...
