<p>A method and a device for controlling user dialogues on a technical installation that is to be controlled or to be maintained, for example, a cash dispenser or a deposit refund device. According to said method or said device, a calculating unit evaluates the data relating to the state of the technical installation and in accordance with said data, emits at least one visual request consisting of textual and/or pictorial instructions (INSTR, CHK) for a user who controls the technical installation. The method processes the data using a directed graph (GRPH) comprising nodes (1000, . . . , 1300 . . . ) and edges (INSTR; CHK) connecting the nodes. Said nodes relate to different maintenance conditions of the installation, and the edges relate to the instructions (INSTR; CHK) for the user for transferring the installation from one of the nodes to another node.</p> |
