Abstract: A poster with an RF IC tag is adhered to a poster adhering unit. ID information of the poster is read from the RF IC tag with an RF IC tag reader and sent to a control device. By using this tag ID information, the control device acquires detailed information on each of advertisement contents of the poster adhered to the poster adhering unit, from a contents server. As a user points out a position of the advertisement contents to which the user paid attention, the control device detects the pointed position from an output of ultrasonic sensors, and provides the user with the detailed information by using a display and a speaker in a contents reproducing unit.

Abstract: On a surface of a decorative paper, vessel perforation of natural wood is reproduced by an offset groove (100) consisting of three steps of embossing grooves (110, 120, 130) of the nesting structure. Respective grooves are such that they are deeper according as positions thereof shift to the internal, and are disposed in a manner to be eccentric in a length direction. Within the groove, a convex bank portion (140) in which the bottom surface is linearly protruded is formed. An embossing plate for processing such an offset groove is prepared on the basis of a vessel cross section pattern inputted by using natural wood. The inputted plane vessel cross section pattern is replaced by an approximate elliptical figure. A three-dimensional virtual vessel perforation model is determined by calculation using the elliptical figure. Equi-depth lines for set predetermined depths are extracted from the three-dimensional model and contour figures of embossing grooves (110, 120, 130) are obtained.
