The server 50 includes a control unit 60. The control unit 60 includes a communication unit 68 for transmitting and receiving information through a communication network and a connection management unit 69 for managing connection of members or teacher members.

The control unit 60 of the server 50 may include a data providing unit 61 for each member and the data providing unit 61 for each member may include a content data managing unit 62 A data analyzing unit 63 for analyzing the content data to provide and selecting the content data, and a data selecting unit 64 for selecting the finally transmitted data. It is of course possible to further include a subscriber management department that manages and operates Internet access, members, or teacher members.

At this time, the database 55 of the server 50 is provided with a subscriber database 55a for providing subscriber information for managing Internet users, members, or teacher members. In addition to the ID information of the member, the subscriber database may store information related to the information provided by each member.

Also, through the present invention, the connection information in which the data information of the additional content to be provided in addition to the digital textbook and the additional content data are connected is stored in the content database 55b.

At this time, the data information of the additional content includes a text file, an image file, a moving picture file, and the like. The connection information for linking the additional contents means information for displaying the data information of the additional contents in the digital textbook, for example, information about the location where the data information of the additional contents are stored, and the like. For example, as the 00 textbook 00 page (x, y), the page information and the coordinate position information on the page may be included.

On the other hand, from the other viewpoint of the connection information, the supplementary content information provided on page 00 of the 00 textbook may be the location where information is stored on the 000 database or the 000 Internet site (URL information).

It is needless to say that the description of the drawings is an example, and it is a matter of course that the server 50 of the present invention can be targeted not only to a member accessor but also to all users who want to provide information. That is, the server 50 of the present invention provides and controls information displayed on a display of a user terminal connected through a wired / wireless Internet or a communication network.

3 is a block diagram illustrating a user terminal.

The user terminal (notebook computer, portable terminal, etc.) shown in FIG. 3 is a terminal of a member, and similarly the teacher terminal has a similar configuration. The user terminal can communicate with a server or a teacher terminal through wired / wireless communication or the Internet.

The control unit (CPU) 25 shown in FIG. 3 is a control means for controlling the entire operation of the computer or the portable terminal used in the embodiment of the present invention. And a memory unit 35 for storing information. The memory unit 35 includes a ROM for controlling a program to be executed by the display device, a RAM for storing data generated at the time of executing the program, And an iipilum for storing data necessary for processing.

The communication unit 36 may be an R / F unit, tunes to an RF channel as a radio frequency, amplifies each input signal, and converts an RF signal received from the antenna into an intermediate frequency signal.

Therefore, information is displayed on the display 21 under the control of the control unit 25, and all the devices using the control unit, the input unit 30, and the flat panel display device correspond to the algorithm of the present invention .

Meanwhile, the input unit 30 of the present invention means all the usual methods of inputting information to the user terminal of the present invention. That is, it includes an input device for inputting information on a display, a mouse input device, a keyboard input device, a voice input device, and the like. Here, 'above the display' means that it is possible to press or touch the display surface, but it is possible to input information on the display without applying pressure or touching the display. It is needless to say that an input / output unit may be further provided. That is, it may further include a numeric key, a menu key, and a selection key, and may include a speaker, a vibration unit, a camera, and the like.

At this time, the memory unit 35 stores the separate data 35a to perform the present invention. The separate data 35a stores digital textbook data, program execution algorithm data (or application), provided content information data, and data necessary for carrying out the present invention.

The digital textbook data refers to data of a digital textbook that can be executed by a user terminal, and is typically electronic data created for displaying a digital textbook on a user terminal or the like. The program execution algorithm means a separate program for carrying out the present invention, and may be generally referred to as an application program. Content information data is data for displaying information extended to a digital textbook. The content information data in the present invention is stored in the database of the server but may be stored as separate data 35a in the memory unit 35 of the user terminal 20 in accordance with the necessity of executing the program.

- Example 1 -

Figs. 4A to 4C show embodiments in which information data is stored. Fig.

4A is a diagram illustrating a method of storing data of an extended supplementary content. (HI-MI-01-0001) (71) is a symbolic representation of the first grade of middle school in history textbooks (of course, there are grade markings and textbooks related to publishing companies) ), And its data type is PDF file (72). 'oo-oo (xx, yy)' 73 is position information for displaying data. As can be seen from this, unit data 1 is information associated with a specific page in the history textbook. Accordingly, the supplementary content information of the present invention is associated with a specific page of the digital textbook, and a position is designated for the additional content to be displayed in a specific page of the digital textbook.

Therefore, in the present invention, the location information 73 must be stored in the data in which the additional content is stored. That is, the information of the coordinates (xx, yy) is stored in 00 page 00 of the textbook. Accordingly, the supplementary content provided in the present invention can designate in which position on the 00 textbook page 00 is displayed.

In addition, the data 74 means data of additional contents provided by the digital textbook. For example, if the additional content is a text file, text data is stored. If the additional content is an image file, photo information is stored. If the additional content is a video file, video data is stored.

It is needless to say that the date and time information on which the additional content information is generated may also be displayed, although not separately shown in the drawing.

4B shows a method of storing data of icon information. In the present invention, when a specific page of the digital textbook is displayed on the display unit (21 of FIG. 3) of the user terminal, an icon is generated on the display unit. When this icon is selected (or clicked) and executed, the information associated with the icon is displayed on the display unit.

Accordingly, when the digital textbook is executed and 00 page 00 is displayed on the display unit, a predetermined icon is displayed on the screen of the display unit. FIG. 4B shows a data storage method in which this method is executed.

As shown in FIG. 4B, for example, when a high school math textbook II is executed and a specific page 00 is displayed on the display unit, an icon 22 determined to be displayed on the screen is displayed on the display unit. For this process, the icon to be displayed is stored in the order 112a for each page, and the position (coordinate) information 112b for displaying each icon on the screen 21 should also be stored. In addition, connection information 112c, which is information on a database storing information to be displayed when the icon 22 is selected, image information 112d of each icon, and summary information 112e, which is a brief description of the icon, are stored.

Here, the image information 112d of the icon is a design image of the icon displayed on the screen 21, and the summary information 112e is text information displayed below the icon or a summary word of information related to the icon.

Also, the same additional content data may be linked to two or more different icons. Therefore, in the embodiment of FIG. 4B, the connection information " MA-000-0001 "corresponding to the first icon may be connection information of another page or another mathematical textbook.

Each additional content data item may be stored as separate unit data. Various types of additional content data can be used, such as text data, image data, and moving image data.

On the other hand, the content data is generally stored in the server, but may be stored in the memory unit of the user terminal if necessary. For example, the additional content data already provided by the member can be stored in the memory unit of the member terminal, and the content data can be stored in the memory unit after a certain area is determined by the member's selection. The contents stored in the memory unit may be displayed in the digital textbook according to the program execution method.

On the other hand, there may be additional icons as shown in the embodiment of FIG. 4C. The additional icon may not be preferentially displayed on the display screen, or may be an icon generated by the user. For example, if the user further designates an icon as a margin in the fourth or icon order N in the icon sequence 113a in FIG. 4, the icon information further designated by the user is stored in the margin.

At this time, the icon images 112d and 113d indicate that the icon images used are all unified, and they are all displayed as image 1, and they represent designed icon images. However, it is a matter of course that the image of the icon can be made different from the embodiment of the present invention.

5 is a diagram of an embodiment showing an execution flow chart of the present invention.

When the user terminal starts and executes the digital textbook, and selects an arbitrary page in the digital textbook, an icon corresponding to the selected page and page of the digital textbook is displayed on the display unit of the user terminal (S150, S154).

As described in the embodiment of FIG. 4B, one or more icons 22 corresponding to the pages of the selected digital textbook are selected, and the selected icons are sequentially displayed on the screen 21 at predetermined positions.

In order to perform the above-described execution in the server, a signal input from the input unit of the user terminal is transmitted to the server. Then, the controller (60 in FIG. 1) of the server (50 in FIG. 1) selects the icon information stored in the database (55 in FIG. 1) to make the information displayed on the display unit send. The CPU (25 in FIG. 1) of the user terminal again displays icon information transmitted to the display unit (21 in FIG. 1).

The CPU 25 may execute the above-described operation in the user terminal (or the computer) by using the icon information stored in the memory unit 35 in accordance with the signal of the input unit 30 of the user terminal 20 And displays it on the screen 21.

When the end signal of the digital textbook is inputted, the CPU 25 of the user terminal ends the execution of the digital textbook. If the digital textbook is connected to the server, the connection with the server is also terminated (S158 - S160).

- Example 2 -

Figures 6 and 7 are views of embodiments illustrating how content data is applied to a digital textbook.

A menu bar 21a is positioned at the top of the screen 21 on which the digital textbook is displayed and a plurality of icons 22 are displayed within the screen 21. [

A title and an extension are displayed on the plurality of icons 22, so that the data type and the summary contents of the information can be known. That is, under the icon as shown in the figure, there is an indication such as "000.hwp", which is a simple title and extension. That is, the program can be run as "hwp" as well as the title.

On the other hand, if one of the plurality of icons 22 displayed in the margin of the screen 21 is selected, the display area 23 is displayed as shown in Fig. 7, and information related to the selected icon is displayed in the display area 23 Is displayed. Here, the icon 22 is selected by focusing or focusing an icon through an input unit capable of inputting information at the top of the display, using a mouse, a separate input device, or clicking on the icon I have chosen it. The display area 23 can be displayed as a pop-up window on a part of the screen 21 or a certain area of the screen 21 can be designated as a frame-free form so as to look like contents in a book.

The above process is for accessing the server 50 through the input device 30 (or a device for inputting information such as a mouse or a keyboard) of the user terminal, and the server transmits the information stored in the database 55 via the wired / To the user terminal. Then, the CPU 25 of the user terminal displays the information on the screen 21 of the user terminal through an information processing process.

When the digital textbook is selected and executed through the input device 30 of the user terminal, the control unit 60 of the server 50 selects the information of the corresponding database 55 and transmits the selected information to the communication interface unit 68 To the user terminal through the wired / wireless Internet.

Also, when a specific icon displayed on the screen 21 is selected through the input device of the user terminal, the selected icon information is transmitted to the server, and the server selects the corresponding information stored in the database and transmits the selected information to the user terminal . That is, information is displayed on the display unit of the user terminal by the above process.

At this time, although a text file is exemplified as the display area of FIG. 7, it is a matter of course that various contents information such as a moving image, an image, a document file, and information through an Internet connection are displayed in the display area.

On the other hand, when a specific icon is selected, the content information data for displaying the content information linked to the specific icon does not necessarily have to be stored in the database 55 of the server. And stored in the memory unit 35 of the user terminal. In this case, if a specific icon is selected, content information linked to a specific icon can be displayed on the display screen 21 through the memory unit 35 of the user terminal without connection with the server.

- Third Embodiment -

An apparatus and method for displaying content data on a digital textbook will be described with reference to Figs. 8 to 17. Fig.

8, a terminal displaying a digital textbook composed of a plurality of pages includes a display unit 1210, an input unit 1220, a communication interface unit 1230, a control unit 1240, a memory unit 1250, .

The display unit 1210 displays the contents of the digital textbook.

The input unit 1220 may be any conventional device capable of inputting information to the terminal. The input unit 1220 includes an input device for inputting information on a display, a mouse input device, a keyboard input device, a voice input device, and the like. Here, 'above the display' means that it is possible to press or touch the display surface, but it is possible to input information on the display without applying pressure or touching the display. It is needless to say that an input / output device may be separately provided.

The communication interface unit 1230 communicates with an external learning management server to transmit and receive information for displaying digital textbook contents and contents information.

The control unit 1240 controls the content of the page corresponding to the input signal of the user to be displayed on the display unit.

In addition, when the content of the digital textbook is displayed on the display unit, the control unit 1240 controls the page selection button to be displayed in an area other than the area where the content is displayed.

Here, the page selection button is an interface for providing a page selection function for selecting any page among a plurality of pages, and the page selection button is in the form of a circle, an ellipse, a polygon, a straight line, or a curve. The page selection button displays a scale indicating the page, and the unit of the scale is proportional to the amount of the entire page. For example, if the entire page of the digital textbook is 50 pages, the scale unit can be set to 5 pages, and if the entire page is 100 pages, the scale unit can be set to 10 pages. If there are many pages and the scale unit is too large to make detailed selection, you can set the page scale first and then set the page scale within the second scale unit. For example, when the entire page is selected from 100 pages and the user selects 36 pages, if 30 pages are selected through the page scale indicated by 10 units, only the 30 pages to 40 pages are enlarged to provide detailed scales on a page basis 36 pages can be displayed to be selectable.

The control unit 1240 controls the search window to be displayed near the page selection button.

The control unit 1240 displays the page including the search word input through the search window so as to be identifiable on the scale of the page selection button.

The control unit 1240 enlarges the page selection button and controls the page selection button to be positioned at the center of the display screen when the page selection button selection signal is input.

The control unit 1240 controls the display unit 1240 to display the content of the page in an area other than the content display area so that the content of the page can be previewed.

The memory unit 1250 may store the content and the additional content in advance and provide the content according to an instruction from the control unit 240. [

Referring to FIG. 9, a menu bar 210a, a page selection button 250, a plurality of icons 220, and a content display area 270 are displayed on a display screen 210 of a digital textbook.

For example, a menu bar 210a is positioned at the top of the screen 210, a page selection button 250 is located at a side of the menu bar 210a, a content display area 270, (220) is displayed.

The title and the extension are displayed on the plurality of icons 220, so that the data type and the summary contents of the information can be known. That is, as shown in the figure, there is an indication such as "000.hwp" below the icon, which indicates a simple title and an extension.

The page select button 250 is displayed in an area other than the content display area 270 where the content is displayed. When the page select button 250 is selected, as shown in FIG. 10, the image is moved to the content display area 270 and the image of the page select button 250 is enlarged and displayed.

The above process is for accessing the server 50 through the input device 30 (or a device for inputting information such as a mouse or a keyboard) of the user terminal, and the server transmits the information stored in the database 55 via the wired / To the user terminal. Then, the CPU 25 of the user terminal displays the information on the screen 210 of the user terminal through an information processing process.

When the digital textbook is selected and executed through the input device 30 of the user terminal, the control unit 60 of the server 50 selects the information of the corresponding database 55 and transmits the selected information to the communication interface unit 68 To the user terminal through the wired / wireless Internet.

Also, when a specific icon displayed on the screen 210 is selected through the input device of the user terminal, the selected icon information is transmitted to the server, and the server selects the corresponding information stored in the database and transmits the selected information to the user terminal . That is, information is displayed on the screen 210 of the user terminal by the above process.

As shown in FIG. 10, the page select button 250 may include a search window 256 that includes a scale 252 that is assigned by displaying a page, and in which words can be input.

The page select button 250 may be, for example, a circle, with a scale 252 on the circular line, and each scale 252 displays each page of the digital textbook.

The user selects a scale corresponding to a desired page on the scale selection page select button 250 or the content of the selected page is displayed in the display area. A method of providing a function to select can be implemented by touching a desired page in the case of a touch panel or selecting a page corresponding to a point on a point where a circle is drawn starting at 12 o'clock.

On the other hand, the scale of the digital textbook is set in proportion to the total number of pages. As the scale unit becomes larger due to the number of pages, detailed page setting may become difficult. Therefore, if the scale unit becomes large due to a large number of pages, it is difficult to select the detail, as shown in FIG. 12, the page scale can be selected in the second scale after the page scale is firstly selected. That is, you can select the first 40 pages and then select 46 pages later.

Referring to FIG. 11, when a search word (for example, "pre-paid wage") is inputted to a search window 256 provided in the vicinity of the page selection button 250, for example, a page including a search word (e.g. If there are a plurality of pages including a search word, a plurality of pages are displayed. As shown in FIG. 11, when the page select button 250 is circular, it is possible to determine at which point of the entire page the selected page is located.

As shown in FIG. 11, when the search result of the search term "Permanent Wage " is found on pages 155 and 170, the pages 155 and 170 are displayed so as to be distinguished from other pages do. As a display method, colors can be displayed differently, images can be displayed with arrows, other scales can be erased, only a corresponding page can be displayed, and display methods can be variously modified. When the user selects either the displayed page 155 or the page 170, the selected page is displayed on the digital textbook screen 210. That is, when a selection signal for either page 155 or page 170 is input, the input signal is transmitted to the server, and the server provides a content matching the page to the user terminal, 210). At this time, a method of inputting a selection signal is to touch the scale for a predetermined time, and there is a method to start at 12 o'clock and stop on the page. Once the page is displayed, or at the same time, the enlarged page select button 250 is returned to its original position, as shown in FIG.

The page select button 250 may further include an icon display button 258 near the search window 256. When a search word is found after selecting the icon display button 258, all the icons including the search word are displayed, A page containing an icon containing the search term is displayed.

14, after selecting the icon display button 258, when a search term such as "Korean Imperial" is input, a page having an icon corresponding to the additional content including the search term " And only the relevant icon of each page is displayed in an arbitrary area 280. [ In FIG. 14, icons corresponding to supplementary contents including a search term "Korean Empire" exist on pages 110, 135, and 150, and icons included in respective pages are listed on the right side.

Of course, if the icon display button 258 is not selected and a search word is input, a page including a search word is displayed. When a specific page is selected, an icon associated with the selected page may be displayed together with the content display area 270 have.

15, when a specific page is selected through the page selection button 250, the selected page can be displayed through the preview window 290. [ At this time, a method of selecting a specific page is as follows. When selecting through the input device at the top of the display. When the rotation is stopped at the position of the page to be selected, the page corresponding to the stopped position becomes the selected page. By allowing the user to select the desired page as if dialing a circle, the user can be curious and entertained.
