A model of dynamic interest management: Interaction analysis in collaborative virtual environment

Abstract

Most previous collaborative virtual environments mainly use spatial aspect to implement interest management. However, it turns to be difficult to manage awareness using semantic or organization considerations, specially in densely populated open space environments. Aiming at this kind of applications, we propose a novel interest management model with dynamic interaction analysis in CVE. Our work is concerned with dynamic interaction in crowds, from which we derive the semantics of user behaviors, more specifically, the alteration of interest focus of users. Above all, we would define the construction of Interest Network. Then an interaction analysis approach is introduced to find out the interest focus of virtual humans. Psychology effects in crowd or a group of participants are also analyzed and incorporated in our approach. Lastly, a prototype virtual conference application is implemented to demonstrate the effects of our model on optimizing collaborative awareness.
