Abstract
In this paper we present the authoring process and the authoring tools for Mixed Reality applications that have been implemented for AMIRE. We introduce concepts that allow non-experts to develop MR applications, with dedicated authoring tools and a well-defined authoring process. The authoring process is reflected in the introduced system architecture. AMIRE is an EU-funded project (IST-2001-34024) where a MR oil-refinery application and a MR museum application are developed.
