This article discusses the application of spatial reasoning techniques in the field of augmented environments. It focuses on resolving spatial references within the flow of a user-computer dialogue. A dialogue-based user guide for a complex machine is presented, utilising a 3D model of the machine and knowledge-based reasoning. The reasoning functionality includes reasoning on the usage of the machine as well as on its construction and location of sub-components. Two issues are discussed. The first issue is the architecture for the user guide supporting both 3D graphical presentations and graphics-based reasoning within the dialogue process. The second issue concerns algorithms for spatial reasoning used in the system. The following algorithms are discussed: the use of functional hierarchy, reduction of dimension, and the use of zones of applicability for spatial references.
