In this paper we describe a virtual environment (VE) which has been implemented for a machine fault diagnostic application which is running on-line in Rautaruukki Raahe Steel plant, Raahe Finland. This hierarchical virtual environment consists of three levels in which information is provided to the plant operators: (1) general guidance for navigating in the virtual plant environment, (2) more specific level for the important serviceable objects and (3) diagnostic and hypertext document application level. The system is implemented in a wireless wearable computer environment which is also discussed. Here we present the experiences of the first virtual prototype system.
