1. A method of interacting with a user to provide information regarding an operation of a device, comprising: receiving speech input from the user; converting the speech into a word sequence; identifying a structure to which the word sequence conforms; providing a structured manual including information related to an operation of a device; providing a visual model to relate a visual representation of the information; interpreting the structure in a context and extracting information and associated visual representation from the structured manual and the visual model, wherein the structure is categorized into one of a “how-to” meaning structure category and a “what-is” meaning structure category, each of the meaning structure categories characterizing the structures of its members as being of a single respective underlying meaning structure, different information being deemed pertinent for the extraction depending upon the meaning category into which the structure of the word sequence has been categorized; and outputting the information to the user, wherein the structure manual and the visual model form a model package that includes a grammar package and a grammar table defined using a grammar specification language, wherein the model package further includes an objects file to define device model information that includes a model of at least one device component, wherein the object file is associated with at least one of a surrounding table, a slide table, a how-to table, and a what-is table, wherein the grammar package includes a set of phrases and sentences as grammars for the speech recognition engine to recognize, and the grammar table includes animation clips associated with the specified grammars, and wherein a categorization into the “what-is” meaning structure category causes the dialog arrangement to: determine an object in the “what-is” meaning structure; determine an object identification of the object; search the surrounding table for information of adjacent objects based on the object identification; search the what-is table based on the object identification for a textual description associated with a feature of the object; and display the textual description when the associated feature is displayed.
