On the other hand, the above-mentioned information means all information files such as image, video, and text.

The server according to the present invention stores data relating to a digital textbook and additional contents extended from data related to the digital textbook.

A user terminal (or a portable terminal or a notebook computer) 20 is a device connected to a server and capable of transmitting / receiving various information through wired / wireless Internet (or communication network) and displaying necessary information on a display.

The user terminal 20 includes a CPU 25 serving as a central processing unit, a display unit 21 for displaying motion pictures, a memory unit 35 for storing various information, an input device for inputting information 30). It is a matter of course that various functions such as a wired / wireless communication system module and a speaker vibration or a key button can be variously imposed.

2 is a block diagram showing the server in detail.

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 device 30 and the flat panel display device correspond to the algorithm of the present invention have.

Meanwhile, the input device 30 of the present invention means any conventional method 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 the information can be input on the display without applying pressure or contacting the display, although it may or may not pressure the display surface. In addition, an input / output unit may be further provided Of course. 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, icons to be displayed are stored in order 112a for each page, and position (coordinate) information 112b for displaying each icon on the screen of the display unit 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 display unit 21, and the summary information 112e is text information displayed under 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 pages of the selected digital textbook are selected, and the selected icons are sequentially displayed at predetermined positions on the display unit 21 .

In order to perform the above-described execution in the server, a signal input from the input device 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 of the user terminal may be stored in the memory unit 35 in accordance with the input device 30 signal of the user terminal 20, Icon information is selected and displayed on the display unit 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 -

Figs. 6 to 12 are views showing an embodiment in which content data whose contents are expanded are displayed in a digital textbook.

Figures 6 and 7 are views of embodiments showing how content data is expanded.

A menu bar 21a is located 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 an icon through an input device capable of inputting information at the top of the display, using a mouse, using a separate input device, or clicking on the focused icon . 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 display unit 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 display unit 21 is selected through the input device of the user terminal, the selected icon information is transmitted to the server, and the server selects corresponding information previously stored in the database and transmits the selected information to the user terminal will be. 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.

Figs. 8 and 9 are diagrams showing icon lists at the bottom of the screen 21. Fig. As shown in FIG. 8, when the lower portion of the screen 21 is raised by a mouse or an input device, an icon window 24 is displayed and an icon list is displayed in the icon window 24. At this time, when the icon list is displayed in the icon window 24, it is displayed in the predetermined order as in the example of FIG. 4B.

A boundary line 24b is displayed in the icon window 24 and a method of moving the boundary line 24b in one direction (left) (a method of selecting a separation line by using an input device or a mouse and then moving the boundary line) can be used. 9, the additional icon window 24c is displayed, and the icons 22 are also displayed in the additional icon window 24c. The additional icon becomes the icon list described in the embodiment of FIG. 4C. That is, the additional icons 24c-1 displayed in the additional icon window 24c are icons that are not displayed on the screen margin of the display unit 21. [ The additional icon 24c-1 is matched with the additional content information connected to the icon displayed on the screen margin of the display unit 21 and other additional content information.

9, when an additional icon window 24c is displayed on the display unit of the user terminal and one of the additional icons 24c-1 not displayed on the screen 21 is selected and moved to the screen margin of the display unit 21 The moved additional icon 24c-1 is additionally displayed on the display unit 21 screen. When the moving state is stored, the moved additional icon is also displayed when the next page is displayed.

For example, if one of the additional icons linked to the page 20 of the mathematics textbook is selected and moved to the margin of the page and the movement status is stored, when the next 20 pages of the mathematics textbook are displayed, It is displayed in the margin. That is, the selected icon changes from the "additional icon list" of FIG. 4C to the "icon list" of FIG. 4B.

Such a storage state can be stored in the personal information, and can be reflected on the display screen when the individual who has moved the icon accesses the server. Of course, the information of the original icon list is always saved so that the additional icon list can be restored to its original state.

10 is a diagram showing an area designated by an icon.

The icons 22 displayed in the margins of the screen 21 are not related to the entire screen. That is, there are a plurality of icons 22-1 and 22-2 next to the area labeled "A" on the screen 21. Only the four icons 22-1 displayed at the beginning are the "A" The remaining icon 22-2 is an icon added through the additional icon window 24c.

As a result, when any one of the icons 22-1 is selected, information associated with the " A "area is displayed as content in the display area.

As described above, the icons displayed in the additional icon window 24c also have corresponding areas. At this time, if one of the icons displayed in the additional icon window 24c is selected, the corresponding area of the selected icon may also be displayed on the screen 21. [

For example, when an arbitrary icon 24e is selected in the additional icon window 24c as shown in Fig. 10, an area (e.g., "A") associated with the selected icon 24e is displayed on the screen 21. In Fig. 10, although a square line is used, various display methods can be used such as differently displaying the background color of the screen differently from other areas of the screen.

11 and 12 are diagrams showing a method of inputting information.

Although description of the separate function of the menu bar 21a is omitted in the drawings of the present invention, it is possible to select a content input from the menu bar 21a or the like, and when the content input is selected through the menu bar 21a, 21, the content creation display 25 is displayed. When the content creation display 25 is selected, the information directory window 25a is displayed as shown in FIG.

When the folder or the files 25b are selected in the information directory window 25a, the selected file 25b becomes a newly created content. That is, when a new content is created, an icon is added, and if the added icon is selected, the selected file 25b is displayed in the display area 23. The icon thus added is stored in the additional icon list of Fig. 4C. The selected file 25b data is stored in a predetermined position in the memory unit 35 of the database or the user terminal of the server.

When the user selects the memo input 26 from the menu bar 21a, the memo input window 26a is displayed. In the memo input window 26a, memo information can be input. . When the user inputs information into the memo input window 26a and then stores the memo, the memo contents are stored, and an icon related to the memo is generated. At this time. The icon-related information related to the memo is stored in the additional icon list of Fig. 4C, and the memo data is stored in a predetermined position in the database 55 or the memory unit 35. [

13 and 14 show an embodiment showing a flowchart of the present invention.

In order to execute the digital textbook as shown in FIG. 13, when the user terminal selects the digital textbook to be displayed on the display unit and connects to the server, the contents of the selected digital textbook are displayed on the display unit (S100 - S102) .

When the icon 22 is selected (or clicked) on the screen margin together with the above-mentioned display, a separate display area 23 is generated and connected to the selected icon in the generated display area 23 Information is displayed (S104 - S106).

Thereafter, when the user terminal finishes executing the digital textbook and terminates the connection with the server, execution of the present invention ends (S108 - S110).

14 is a flowchart showing an information input method.

When the user terminal accesses the server and executes the digital textbook and selects the information input instruction in the digital textbook (S120 - S124), information can be input through the window displayed on the display unit.

This process is performed by inputting and selecting information through the input device of the user terminal 20 and transmitting the selected information to the server 50 so that the control unit 60 of the server transmits the information of the database 55 to the display unit 21).

If the selection of the content input window is input in the user terminal, the content directory display window is displayed on the screen. In the content directory display window, the arbitrary folder width is stored in the selected folder or file when the file is selected (S126-S130). At this time, a new icon is generated and the information of the generated icon is stored in the additional icon list of FIG. 4C, and the newly selected content data is stored in a database of the server or a predetermined storage location of the memory unit of the user terminal.

Therefore, when an icon generated in the display unit of the user terminal is selected, the information stored when the icon is generated is displayed in the display area 23 in the display unit.

In addition, the above process is performed by inputting information through an input device of a user terminal and transmitting the input information to a server through a communication interface unit and a wired / wireless Internet network. The control unit of the server transmits the directory information to the user terminal again through the stored information of the database. Then, the transmitted information is displayed on the display unit 21 of the user terminal.

That is, the icon is created by the member, and the icon created by the member can be displayed through the additional icon window 24c.

Meanwhile, when the selection of the input of the memo is inputted in the process of inputting the selection of the content input window, the user terminal generates a memo input window on the display unit of the user terminal and receives the information in the memo input window with letters or pictures. When the newly memorized information is inputted, the new memorized information is stored in the memory and a new icon is generated (S132 - S134).

Therefore, when the selection of the newly generated memo icon is input on the screen, the user terminal displays the memo content stored when the memo icon is selected in the display area 23. At this time, the contents of the memo can be stored in the database of the server or can be stored in a predetermined position of the memory unit in the user terminal.

Thereafter, when the user terminal terminates the execution of the digital textbook (electronic book) and disconnects from the server, execution of the digital textbook of the present invention ends (S136-S138).

- Example 3 -

Fig. 15 is a view showing still another embodiment of the present invention.

Selection or click of the icon 22 on the user terminal is not a selection operation by putting the cursor on the icon or putting the input rod or the finger on the icon through the input device. The summary content of the information associated with the icon is displayed through the separate window 22b. That is, the information stored in the summary text shown in Figs. 4B and 4C is displayed in the separate window 22b.

16 and 17 show an embodiment in which members are grouped.

In the embodiment of the present invention, when a new icon is generated in principle, when the member who created the icon executes the digital textbook, the controller of the server or the CPU of the user terminal calls the information of the icon newly generated, .

Therefore, when a plurality of members are gathered to form a group, for example, when 20 members form 123 groups, all the members belonging to the group 123 can see the information associated with the newly created icon.

16 shows an additional icon window 25 is additionally displayed when the boundary dividing line 24b of the icon window 24 is moved once again and an icon displayed in the separate icon window 25 is displayed Icon.

As described above, the icon generated by the predetermined group member is selected or displayed on the screen, and new content information can be displayed on the screen of the digital textbook.

17 is a diagram of an embodiment for storing an additional generation icon for each group.

In the embodiment of the present invention, when storing an additional creation icon for each group, the information 114 about the group and the information 115 of the members to which the group belongs are stored. The information about the group includes information about the name of the group, Etc., and the member information belonging to the group may include the name name, ID, password, etc. of the 123 group member.

Such information is stored in a database of the server or in a predetermined storage of the memory part of the user terminal.

On the other hand, in the case of inputting a memo, if the memo is a memo that can be shared by the same group, an additional memo can be stored in the group icon of Fig.

Also, although not described in the drawings of the other embodiments in the present invention, when a member creates an icon, it can select whether it is an additional icon stored in the storage method of FIG. 4C or an additional icon stored in the storing method of FIG. 17 . That is, it is possible to select whether it is a personal addition icon or an additional icon for a group, and in the case of a personal addition icon, only the member who created the icon can view the icon information.

[ That is, in the 00 textbook 00, the icon determined to be displayed on the display margin or the content information linked to the predetermined important icon is sequentially displayed on the display area 23.

When the next mark 22b displayed on the upper right of the display area 23 in Fig. 18 is selected, the information associated with the icon in the next order of the current icon is displayed in the display area 23. That is, when the information associated with the icon 3 is displayed in the display area on the page 50 of the high school mathematics II textbook, if the next mark is selected, the information associated with the icon 4 on the 50th page of the high school mathematics II textbook is displayed in the display area . At this time, it is of course possible to select the previous icon information display in the display area through the next page (next) mark 22b, and then to select the icon information display.

When a content is displayed in the display area 23, a program such as a text file, a moving picture file, an image file, or an Internet connection can be used.

In order to realize this, the order of contents to be displayed is stored in the database 55 of the server 50 or the memory unit 35 of the terminal, and the control unit 60 (or the CPU 25) (27) is selected, the content is displayed in the display area (23) according to the storage order.

At this time, the selection means to select or click a specific icon through an input device or a keyboard mouse to input information through the top of the display.

Fig. 19 is a view of an embodiment showing that the order of contents displayed through the display area can be arbitrarily adjusted. You can select the icon you want to change order and move the order by dragging. If the continuous display icon 22a is selected after the position has been shifted in this way, the contents are displayed in the changed order in the display area 23.

At this time, icons are sequentially stored in the present invention as shown in FIG. 4B, FIG. 4C, or FIG. However, as in the embodiment of FIG. 19, when the order of the icons is moved by the order moving method, the order in which the icons are stored can be changed.

That is, in the example of FIG. 4B, it means that the icon of the third order is changed to the order of the second order, and the icon of the second order is changed to the order of the third order.

At this time, the method of adjusting the order of the icons is not necessarily limited to the embodiment shown in Fig. For example, the icon list may be displayed on the screen of the display unit 21, and the order of the icons may be changed by the user adjusting the icon order and selecting the save in the icon list.

On the other hand, when the order of displayed contents is changed, the original sequence is also stored in the database 55 of the server 50 or the memory unit 35 of the terminal, and the newly changed sequence is also stored.

20 is a diagram of an embodiment showing an overall flowchart of the present invention.

When the user terminal of the present invention executes the serviceable digital textbook and selects a desired page, the selected page of the digital textbook is displayed on the screen of the display unit 21 (S170 - S172).

Thereafter, the user terminal displays an icon corresponding to the page selected on the digital textbook (page displayed on the current screen) on the screen of the display unit 21 according to predetermined rules (S174).

At this time, the display rule of the predetermined icon is as follows.

The important icons are preferentially displayed on the screen of the display unit as described with reference to FIG. 4B.

Icons that display notes are displayed on the screen even if they are not important icons.

If there is a group addition icon, it can be displayed on the screen even if it is not an important icon.

Each icon is displayed in a predetermined order.

Each icon is displayed at the specified position.

In addition, a feature of the information associated with the icon can be displayed directly below the icon image.

When one of the displayed icons is selected, the information associated with the selected icon is displayed in the display area 23 (S176-S178).

On the other hand, when the continuous display icon 22a is selected from the displayed icons, the information connected to the icon is displayed in the display area in the order of the predetermined icons (S180). In this case, the predetermined sequence can be referred to FIGs. 4B and 4C. The information associated with the memo icon is not displayed in this order. That is, only when the memo icon is selected, the memo information associated with the memo icon is displayed on the screen of the display unit 21.

Then, when the close (or end) function of the display area is selected, the selected page of the digital textbook is selected. However, if the mark of the next page (22b in FIG. 18) is selected in the display area, (S182 - S184, S186).

By distinguishing the icon storage method by the above algorithm, it is possible to transfer memos between members or between the same groups. However, the memo can be managed separately from other icons (S188 - S190).

On the other hand, the above-mentioned algorithm control is executed by the control unit of the server or the CPU of the user terminal, and the data for executing the algorithm is stored in the database of the server or the memory unit of the user terminal.

Thereafter, the user terminal can return to the screen of the previous page selected first, and when the execution of the digital textbook is finished, the program is terminated (S188).
