Abstract
In this paper we describe the way in which emotion‐related data can efficiently be exchanged between participants in a large‐scale networked virtual environment. This type of metadata is extracted from real‐time captured video streams using off‐the‐shelf webcams and applied onto a two‐dimentional (2D) stylised avatar; thereby improving the immersion the user experiences while navigating and communicating in the virtual world. As emotion‐related data—once processed through the system—can be considered a specific type of state information, a generic networked virtual environment architecture can be used to distribute the information between participants. We have opted to extend the in‐house developed architecture for large‐scale virtual interactive communities (ALVIC‐NG) architecture to be able to process the information flows. We will show that the inclusion of this new type of information does not have a detrimental effect on the scalability of the system. Copyright © 2009 John Wiley & Sons, Ltd.
