Linking between real and virtual spaces: Second year report for the Esprit i3 project eRENA, Siena, Italy, October 20 - 22, 1999

This paper is concerned with developing the concept of the Mixed Reality stage as a networked layering of physical space and virtual environments. These environment allow for interaction and communication of multiple users enabled through intuitive, free body interfaces. The deliverable discusses three main issues: (1) A characterisation of Mixed Reality approaches and techniques uncovering the requirements for Mixed Reality stages, (2) The technical development and implementation of a VRML 2.0 based multi-user system, which is enabled by an intuitive interface environment and supports Mixed Reality stages: the eMUSE - electronic Multi User Stage Environment, (3) Trials and evaluation of the eMUSE prototype in a public setting with untrained users and in a theatrical setting with professional performers resulting in a networked interactive stage concept in year 3. The innovative aspect of this approach is the combination of the VRML based multiuser system, the intuitive interface and the focus on the interactive experience in different settings. The goal is to produce an operating system for Mixed Reality stages through transdisciplinary exchange
