摘要： A display device or method for an operating procedure which enables an accurate transmission of an operating procedure of a target element to an operator, which enables the operator to understand the operating procedure promptly and rationally and which enables the operator to look at functional elements on the screen from a desired direction by the operation of the operator. Three-dimensional dynamic scene information is exploded based on three-dimensional scene information of mono-elements and three-dimensional procedure information which shows the handling procedure of functional elements. The three-dimensional scene information is structured by coordinates information of a desired reciprocal viewpoint and is displayed as exploded three-dimensional graphics in the display device. The coordinates information of a desired reciprocal viewpoint signifies a locus of time or a sequence of a variable which shows a reciprocal position and direction between an object and a viewpoint, and signifies time-series data of coordinates information which is suitable for showing the operating procedure.

摘要： Described is a processing system for knowledge data base in which indices representing the degrees of certainty of causal relations between an event and plural events relevant to the first-mentioned event are stored. The system has an input unit for inputting information on those actually experienced among events inferred based on the knowledge data base, an updating unit for updating the indices so that, among the plural causal relations, the certainty of the causal relation corresponding to the actually experienced event inputted by the input means is made higher relative to the certainties of the other causal relations, and a storing unit for storing back the thus-updated indices again in the knowledge data base. This allows an expert system with the processing system to perform inference with higher certainty.
