1. A method for contextualizing operating procedures, comprising: receiving a set of procedures, each procedure including text describing user actions which are to be performed on a physical device to implement the procedure; providing a model of the device which refers to a set of components of the physical device on which user actions are performable, for each of the components in the set, the device model providing a state chart which links an action performable on the component with states assumed by the component before and after the action is performed; for each procedure in the set, segmenting the text into a sequence of instruction steps, each instruction step including an action to be performed on one of the components of the device that is referred to in the device model; receiving a request for one of the procedures; retrieving the sequence of instruction steps for the requested procedure; receiving device data from the physical device; for each of a plurality of the instruction steps in the retrieved sequence, contextualizing a current one of the instruction steps, based on the device data and the state chart of the respective component referred to in the device model; and outputting a representation of the contextualized instruction step to a display device.
