Patent US 5,771,043

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.
