<p>PURPOSE: To generate a presentation screen without using an exclusive authoring tool. CONSTITUTION: A card containing a card change-over designating pattern is generated by a drawing tool, etc., stored in a card database 106, taken-out from the database 106 at the time of executing presentation so as to be written in VRAM 102 and displayed in a display device 101. When the position of a certain pattern in the card under display is designated by a mouse 104a, a picture around the designated position is picked-up from VRAM 102 so as to be transmitted to a picture recognizing device 110 and it is recognized which pattern of a dictionary 111 coincides with it. When the pattern is the card change-over designating one, it is checked whether or not a numerical value exists in the neighborhood of it. At the time of existence, it is changed-over into the succeeding or preceding card for the portion of the numerical value so as to be displayed by following the definition of the dictionary 111 which corresponds to the pattern.</p> |
