Description REVERIE is a revolution in online social networking. It is safe, collaborative, online environment which brings together realistic inter-personal communication and interaction.REVERIE will bring online social networking into the real-world with interaction and communication based on what people do and say and how they act. In other words, REVERIE will bridge the physical/digital divide, making communication in social networks more reflective of how people interact in the real world. To this end, a key focus in the project’s work plan is on developing/integrating multi‐modal and multi‐sensor signal acquisition tools for capturing, and subsequently representing and recreating both 3D environments and human activities therein. REVERIE must also focus on how users will experience this interaction and the digital online environment in which it takes place. 3D and immersive audio‐visual display technologies have developed to such an extent in recent times that the technology is now considered de rigueur for ensuring the most attractive user experience. Further, REVERIE intends to bring new dimensions to such experiences, introducing aspects of autonomy into avatar behaviour, and capturing and representing user emotional state as well as physical activity, in order to provide a recreation that is as rich as possible.
