Requesting the server 10 to acquire data related to the given search condition, and presenting the obtained related data to the user as information in this format as shown in FIG.
FIG. 6 is a flowchart showing the operation of the first embodiment of the present invention.

Step 101) When a user tries to browse information in a book form, the user refers to the book information interface unit 30 with a URL for referring to the information to be browsed.
Enter As a result, the search request generation unit 22 stores the URL
Is stored. Step 102) The input URL is sent to the information candidate acquisition unit 21 and transferred as a search request to the candidate information generation unit 11 of the server 10.

Step 103) Next, the candidate information generation unit 11 of the server 10 sends a list of the main type information candidates indicated by the URL sent from the candidate information storage unit 12 and a display of the main type information. The condition is acquired and sent to the information candidate acquiring unit 21 as data having a data structure as shown in FIG. Step 104) The candidate list is stored in the candidate information selecting unit 23.
The attribute value data relating to the display area of the client 20 is obtained from the attribute information storage unit 24 and stored in the buffer in the middle. The attribute value data has a structure as shown in FIG. 8. For example, the size of the display area of the book information interface unit 30 by the number of vertical and horizontal dots, the physical length of the diagonal line of the display area, or There are vertical and horizontal physical lengths of the display area, resolution values, and the like.

Step 105) The candidate information selecting section 23 compares the value of the attribute of the client 20 with the value of the condition for displaying each information in the candidate list. As a means of comparison, for example, in the case of comparing the number of dots in the vertical direction of the screen, in the present invention, it is necessary to display the data in the book format in the display area of the client 20, as shown in FIG. , FIG. 7 shows the number of vertical dots in the screen size of FIG.

Step 109) The book type data transferred to the client 20 includes the information displayed on the surface of the book with a nail heading, such as a chapter title, and the information on the currently opened page, for example. In order to obtain image data that can be displayed by the user, the book information expression unit 26 generates an image such as a nail head and a book frame shown in FIG. As a result, information in this format as shown in FIG. 5 is displayed.

As shown in FIG. 7, the data structure of the candidate list for book type data in the server 10 in this embodiment is expressed using at least the URL for book type information and the number of dots on the screen. Document that expresses the vertical and horizontal dimensions when displaying the book information, the physical size of the optimal display area that was targeted when the book data was designed, and the multimedia information. Has a font size that indicates the size of the most commonly used characters.

Further, the client 20 in the present embodiment
As shown in FIG. 8, the attribute information is composed of at least a value used for comparison with the name of the condition and a comparison operator element for comparison. [Second Embodiment] In the present invention, even when the size, resolution, color and the like of the information display area of the client are different, when the same information is accessed from the user, it is suitable for the user environment. The present invention is intended to provide a method for transmitting information based on characters such as a book or a card on a computer. It is necessary to consider not only the number of dots in the vertical and horizontal display areas, but also the physical size of the display area, from the standpoint of a person viewing.

For example, main pattern information created for a display area of 1024 dots in width and 768 dots in height and 17 inches in diagonal length is, for example, 1 inch in width with a diagonal length of 12 inches.
In the case of displaying characters in an area of 024 dots and 768 dots vertically, assuming that standard characters are represented by, for example, 16 dots each in the vertical and horizontal directions, as shown in FIG.
On a 7-inch display area, characters are displayed with a character of about 5 mm in length and width, whereas on a 10-inch display area, 2.
The characters are small, about 8 mm, and can be displayed, but are difficult for humans to read.

Therefore, in the present embodiment, in order to secure the size of characters that can be browsed by the user, the book type information expression generated by the book information expression unit 26 is extended to the system shown in FIG. By providing the function of reducing the size, multimedia information optimal for the environment is provided according to the physical size of the display medium used by the user. As shown in FIG. 4, the system according to the present embodiment has a configuration in which a candidate information standardizing unit 27 and a main information scaling display generating unit 28 are added to FIG.

The candidate information standardizing unit 27 acquires the physical size information of the display area and the recommended character size information from the attribute information storage unit 24, and obtains the book type sent from the information candidate acquiring unit 21. The size of the display area required by the data candidate data is converted to the size of the area required to display the data in the recommended character size. This information scaling display generation unit 2
8, in order to display the data in the book format generated by the book information representation unit 26 in accordance with the display area, the information on each page displayed in the book form is enlarged or reduced, and the book information is displayed. Display is performed on the interface unit 30.

FIG. 11 is a flowchart showing the operation of the second embodiment of the present invention. Step 201) In the client 20, the process of transferring the list of the main type information candidates to the information candidate obtaining unit 21 is the same as Steps 101 to 103 of the first embodiment described above, and therefore the description is omitted. . Step 202) The list of candidates transferred to the information candidate obtaining unit 21 is transferred to the candidate information standardizing unit 27. The candidate information standardization unit 27 acquires data of the physical screen size and the recommended character size from the attribute information storage unit 24.

Step 203) Based on the physical screen size and the recommended character size, and the values of the optimum screen size and the standard font size in the candidate list shown in FIG. A conversion coefficient is calculated to calculate a required display area value at the time of display, and the conversion coefficient is multiplied by the display area value added to the main model data. As a calculation method in the present embodiment,
For example, if the size of the physical area of the client 20 is 1
When the recommended character size is 0 dot and the dot size is 20 dots, for example, the following calculation is performed on the candidate list as shown in FIG. 12 to obtain a conversion coefficient.

[0037]

(Equation 1)

Step 204) The size of the display area of each candidate to the main type data is multiplied by the conversion coefficient, and the client 2
When displaying with the recommended character size of 0, the size of the display area required by each model data is obtained. For example, in the case of the candidate list shown in FIG. 12, if the recommended character size of the client 20 is 12 and the screen size of the client 20 is 12 inches, the required display area is number 1. Is 20 × 21) ÷ (14 × 12) = 2.5, and the required display area size is 900 × 2.
5 = 2250 dots and 650 × 2.5 = 1625 dots vertically.

Number 2. In the case of this type data, the conversion coefficient is 1.77, which is 1593 dots in width and 1150 dots in height.
It becomes a dot. Number 3. In the case of this type data, the conversion coefficient is 1.29, which is 903 horizontal dots and 645 vertical dots. Step 205) The candidate list for the main data converted into the required display area size is compared with the display area size of the client 20 in steps 105 and 106 of the first embodiment. This process is the same as in the first embodiment, and a description thereof will be omitted.

Step 206) If all the conditions have been compared, the process proceeds to step 207; otherwise, the process of step 205 is repeated. As a result, for example, the display area of the client 20 is 1024 dots wide,
In the case of having a size of 768 dots vertically, in the first embodiment, the number 1. Data is 900 dots in width and 650 dots in height, so this data is selected. In this case, if this model data is designed for a 21-inch screen size, Is 70% of the size when viewed on a 21-inch screen, and even if the number of dots used is the same, a character smaller than the assumed size is displayed. .

In the method of the present embodiment, the size of the display area converted in the processing of steps 205 to 206 and the size of the display area of the client 20 are compared. , Number 2. Is not selected because it exceeds the size of the display area.
Is selected. Step 207) From the main information acquisition unit 25, the server 1
A URL for making a request for information acquisition is transmitted to the main type data transfer unit 13 of No. 0.

Step 208) When the type data is selected from the candidate list, the type data is obtained from the server 10 and sent to the type information obtaining unit 25. The processing in this process is the same as that in step 107 in the first embodiment described above, and a description thereof will not be repeated. Step 209) In the main type information acquisition unit 25, the server 1
Data obtained from the book information interface unit 30
In order to display it on the upper part, in this information expressing unit 26, FIG.
, An image such as a nail head and a book frame is generated, combined with the image to be displayed, and sent to the book information enlarged / reduced display generation unit 28.

Step 210) The book information interface unit 30 executes step 20 when displaying book type data.
Based on the value of the conversion coefficient obtained in step 2, the information of this model is enlarged or reduced. As a result, FIG. Data is horizontal 7
Instead of being displayed in the area of 00 dots and 500 dots vertically, it is enlarged and displayed in the area of 903 horizontal dots and 645 vertical dots.

For this reason, even if the displayed main form data is displayed on a display having a width of 1023 and 768 dots in a 12-inch display area, it is recommended by the client 20 when viewed from the user. Multimedia information can be browsed in the size of characters. As an enlargement / reduction method, for example, it is possible to perform enlargement / reduction processing as an image displayed on the book information interface unit 30.

As another method, if information is decomposed into elements such as character codes, figures, and background images,
For character codes, the font size in this type data is multiplied by a conversion coefficient to create a character image, and information represented by dots such as background images and still images is enlarged as an image, and the data of each element is May be combined into data to be displayed on the book information interface unit 30.
