Abstract: The position relating to a content can be displayed on map information using a portable storage medium. With respect to a content the visual information of which is to be displayed on a display unit (19), a display control unit (control unit 21) displays the visual information of the content on the map information. If a first identification value among a plurality of identification values of the content cannot be found, a content is extracted from the contents stored in the portable storage medium (12) so that the extracted content has an identification value which matches with any of the plurality of identification values other than the first identification value. The visual information of the extracted content is displayed on the map information.

Abstract: A method of analyzing mechanical actions on an object comprised of a plurality of components includes the steps of creating a model having a general exterior shape of the object without regard to structural details of the components, obtaining separate elasticity coefficients of the model in respectively different spatial directions based on rigidities of the object, and analyzing mechanical actions on the object based on the model and the elasticity coefficients.
