Staging the space of mixed reality—reconsidering the concept of a multi user environment

This paper presents our work and research findings on developing the concept of a multi-user shared environment for culture, performance, art and entertainment. It introduces artistic concepts of multi-user spaces focusing on the notion of virtual space as a stage setting and on the behaviours and interactions of people within it. The VRML based demonstrator "Murmuring Fields" presents a mixed reality shared environment installation for several users based on a decentralised network architecture and supporting external participation across internet and in shared physical space. The notion of user representation is replaced by the notion of user enactment, treating the concept of avatar as an extended body of communication. "Murmuring Fields" presents a prototype of an information space where real space becomes the interface to the virtual enabled by an invisible and intuitive full- body interface environment. Following our goals for user embodiment and group interaction, connecting real and virtual environments as a mixed reality, we have developed the e-MUSE system (electronic multi user stage environment). Derived from an artistic point of departure, the installation "Murmuring Fields", e-MUSE is the underlying platform for networked communication, interface, rendering and display organisation. It uses VRML to implement mixed- reality environments in which visitors' exploration and experience of virtual space are connected to real space as well as other participants' experiences.
