DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, various technically preferable limitations are added to the embodiments described below for carrying out the present invention. Therefore, the technical scope of the present invention is not limited to the following embodiments and illustrated examples.

[0012] [Configuration of Learning Support System 100] First, the configuration of the learning support system 100 according to the present embodiment will be described. FIG. 1 is a diagram showing an example of the overall configuration of the learning support system 100 according to the present embodiment. As shown in FIG. 1, the learning support system 100 is configured by connecting a user terminal 1 and a server 2 so that they can transmit and receive data via a communication network N including a LAN (Local Area Network), the Internet, and the like. Note that the number of user terminals 1 is not particularly limited.

[0013] [Configuration of User Terminal 1] User terminal 1 is equipped with a learning support application 121, and is a terminal that functions as a display device and a learning support device. As the user terminal 1, for example, a tablet terminal, a smartphone, a PC (Personal Computer) or the like can be applied.

[0014] As shown in FIG. 1, the user terminal 1 includes a control unit 11, a storage unit 12, an operation unit 13, a display unit 14, an imaging unit 15, a communication unit 16, and the like, and each unit is connected by a bus 17.

[0015] The control unit 11 includes at least one CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. The CPU of the control unit 11 reads programs and data stored in the ROM or the storage unit 12, and executes various processes using the RAM as a work area. The control unit 11 functions as the display control means and acquisition means of the present invention in cooperation with the learning support application 121 stored in the storage unit 12.

[0016] The storage unit 12 is composed of a non-volatile semiconductor memory, a hard disk, or the like, and stores various programs and data used in the programs. The storage unit 12 is not limited to one built in the user terminal 1, and may include an external recording medium such as a memory card that is detachable from the user terminal 1.

[0017] In the present embodiment, a Web (World Wide Web) browser is stored in the storage unit 12. Further, a learning support application 121 is stored in the storage unit 12. The learning support application 121 is a web application program for the control unit 11 to execute various processes related to learning support including electronic sticky note display processing described later.

[0018] The operation unit 13 is equipped with a touch panel superimposed on the screen of the display unit 14. The operation unit 13 also includes various operation buttons, including a shutter button for the user to initiate shooting. The operation unit 13 detects user operations on the operation buttons and operations on the screen of the display unit 14, and outputs the operation information to the control unit 11.

[0019] The display unit 14 is composed of an LCD (Liquid Crystal Display) or an EL (Electro Luminescence) display, and displays various information according to the display information instructed by the control unit 11.

[0020] The imaging unit 15 is composed of an imaging lens, an image sensor such as a CCD (Charge Coupled Device) or CMOS (Complementary Metal-oxide Semiconductor), and an A / D conversion circuit. The optical image that has passed through the imaging lens is converted into a two-dimensional image signal by the image sensor, and image data is acquired.

[0021] The communication unit 16 performs communication control for communicating with external devices, including the server 2, via a communication network N, which includes a LAN (Local Area Network) and the Internet.

[0022] [Server 2 Configuration] Server 2 is a device that generates graph creation information and headword display information (described later) in response to requests from the learning support application 121 on user terminal 1, and also stores electronic sticky note information generated on user terminal 1.

[0023] As shown in Figure 2, the server 2 consists of a control unit 21, a storage unit 22, an operation unit 23, a display unit 24, a communication unit 25, etc., and each unit is connected by a bus 26.

[0024] The control unit 21 is configured to include at least one CPU, ROM, RAM, etc. The CPU of the control unit 21 reads programs and data stored in the ROM and storage unit 22, and uses the RAM as a work area to execute various processes.

[0025] The storage unit 22 is composed of non-volatile semiconductor memory, a hard disk, or the like, and stores various programs and data used by those programs. The storage unit 22 is not limited to being built into the server 2, but may also include an external recording medium such as a memory card that can be attached to or removed from the server 2.

[0026] In this embodiment, the storage unit 22 stores a program for realizing the functions of a web server. Furthermore, the memory unit 22 stores a dictionary database 221, a user database 222, and an electronic sticky note database 223.

[0027] Dictionary DB221 is a database that stores headword display information for headwords identified by the entry number (and type number, if applicable) of electronic dictionaries identified by the dictionary content number, corresponding to the dictionary content number, entry number, and type number. The dictionary content number is the dictionary identification number. The entry number is the identification number for the headword (word). The type number is the identification number for compound words, diagrams, and other elements within the headword. The headword display information is information for displaying the headword and explanatory text such as its part of speech, meaning, etymology, and usage examples.

[0028] User DB222 is a database that stores user registration information for users who use the learning support service provided by the learning support application 121. User registration information includes, for example, user ID, password, username, age, gender, place of residence (prefecture, etc.), email address, etc.

[0029] The Electronic Sticky Note DB223 is a database that stores information about electronic sticky notes generated by user terminal 1. The Electronic Sticky Note DB223 stores information about electronic sticky notes (including electronic sticky note data, linking information indicating the link between electronic sticky notes, information about the operation tool corresponding to the electronic sticky note, and location information of the electronic sticky note and operation tool in the notebook, etc.) associated with, for example, the user ID and notebook name.

[0030] The operation unit 23 includes a touch panel, keyboard, various operation buttons, etc., superimposed on the screen of the display unit 24. The operation unit 23 detects user operations on the keyboard and operation buttons, as well as operations on the screen of the display unit 24, and outputs the operation information to the control unit 21.

[0031] The display unit 24 consists of an LCD, EL display, etc., and displays various information according to the display information instructed by the control unit 21.

[0032] The communication unit 25 performs communication control for communicating with external devices, including the user terminal 1, via a communication network N, which includes LANs, the Internet, etc.

[0033] [Operation of Learning Support System 100] Next, we will explain the operation of the learning support system 100. When the user terminal 1 detects a command to start the learning support application 121 via the operation unit 13, the control unit 11 performs login authentication and starts the learning support application 121. Then, the control unit 11 works in cooperation with the learning support application 121 to execute the following processes.

[0034] When the control unit 11 detects a display instruction for the notebook 141 (see, for example, Figure 3) via the operation unit 13 while the learning support application 121 is running, it displays the notebook 141 on the display unit 14. Here, the notebook 141 is a workspace for displaying electronic sticky notes, which serve as a display area for learning-related text, handwritten text, links to web pages, image files and PDF (Portable Document Format) files, images captured by the camera unit 15, function graphs, and information looked up in a dictionary. In other words, the notebook 141 records and displays learning materials such as information entered or handwritten by the user for learning, as well as links to web pages related to learning, images, captured images, function graphs, and content looked up in a dictionary, on electronic sticky notes.

[0035] Notebook 141 displays a group of buttons, including a camera button 141a, a file button 141b, a save button 141c, and others, for instructing the creation of electronic sticky notes. The camera button 141a is a button used to instruct the generation of an electronic sticky note displaying the captured image taken by the shooting unit 15. The file button 141b is used to retrieve files such as image files, video files, and PDF files, and to instruct the system to generate an electronic sticky note displaying the image from the retrieved file. The save button 141c is a button used to instruct the system to save the data of the selected electronic sticky note from the generated electronic sticky notes to a predetermined storage location.

[0036] When the operation unit 13 detects that the camera button 141a or the file button 141b has been pressed, the control unit 11 executes the image sticky note display process shown in Figure 2. The image sticky note display process is executed in cooperation with the control unit 11 and the learning support application 121. The image sticky note display process will be described below with reference to Figure 2.

[0037] In the image sticky note display process, first, the control unit 11 acquires an image to be displayed on the electronic sticky note (step S1). When the camera button 141a is pressed, the control unit 11 activates the shooting unit 15 and, for example, acquires the image captured by the shooting unit 15 at the moment the user pressed the shutter button as the image to be displayed on the electronic sticky note. When the file button 141b is pressed, the control unit 11 displays a list of image files, video files, and PDF files stored in the storage unit 12 on the display unit 14, and retrieves the image of the file selected by the user from the list screen from the storage unit 12 or storage unit 22. If the selected file is a PDF file, the control unit 11 retrieves the PDF file from the storage unit 12 and converts it to an image format.

[0038] Here, the user can take a photograph of an object (for example, a book, a pamphlet, the display screen of a scientific calculator, or the display screen of an electronic dictionary) that displays a predetermined symbol (in this embodiment, for example, a two-dimensional code such as a QR code), or select an image containing a two-dimensional code stored in the memory unit 12 or memory unit 22.

[0039] Next, the control unit 11 generates a first electronic sticky note on which the acquired image is displayed (step S2).

[0040] Next, the control unit 11 performs the process of recognizing a two-dimensional code from the acquired image (step S3).

[0041] Next, the control unit 11 determines whether or not a two-dimensional code was recognized from the acquired image (step S4). If the control unit 11 determines that a two-dimensional code has been recognized from the acquired image (Step S4; YES), it determines whether the information indicated by the two-dimensional code is a URL (Uniform Resource Locator), function information, or dictionary information (Step S5). Here, for example, the information decoded from a two-dimensional code representing function information contains a special pattern indicating that it is a two-dimensional code representing function information. Similarly, the information decoded from a two-dimensional code representing dictionary information contains a special pattern indicating that it is a two-dimensional code representing dictionary information. The control unit 11 determines whether the information represented by the two-dimensional code is a URL, function information, or dictionary information based on whether or not the information decoded from the two-dimensional code recognized from the acquired image contains these special patterns.

[0042] If the control unit 11 determines that the information indicated by the two-dimensional code is a URL (step S5; URL), it obtains the URL information indicated by the two-dimensional code (step S6) and proceeds to step S9. For example, the control unit 11 determines whether the string obtained by decoding the two-dimensional code is in URL format, and if it is in URL format, it acquires that string as URL information. If the information decoded from the two-dimensional code is not in URL format, the control unit 11 proceeds to step S20.

[0043] If the control unit 11 determines that the information indicated by the two-dimensional code is function information (step S5; function information), it acquires graph creation information based on the function information indicated by the two-dimensional code (step S7) and proceeds to step S9. In step S7, the control unit 11 first obtains function information from the information obtained by decoding the two-dimensional code. Function information is information necessary for creating a graph. Function information includes, for example, the format of the graph (y=x, y=x 2 This includes, but is not limited to, information such as the number of steps (increment width), and the drawing range (the x-range to be drawn). Next, the control unit 11 transmits the acquired function information to the server 2 via the communication unit 16 and requests the transmission of graph creation information. When the control unit 21 of server 2 receives function information and a request to send graph creation information from user terminal 1, it calculates the plot points and other elements necessary to create the graph based on the received function information, and transmits the calculation results as graph creation information to user terminal 1 via the communication unit 25. User terminal 1 receives graph creation information transmitted from server 2 via communication unit 16.

[0044] If the control unit 11 determines that the information indicated by the two-dimensional code is dictionary information (step S5; dictionary information), it obtains headword display information based on the dictionary information indicated by the two-dimensional code (step S8) and proceeds to step S9. In step S8, the control unit 11 first obtains dictionary information from the information obtained by decoding the two-dimensional code. The dictionary information is information for identifying the headwords (words) registered in the search history of the electronic dictionary and the headwords registered in the vocabulary list. The dictionary information includes, for example, the dictionary content number, item number, and type number for each headword (word) registered in the search history, and the dictionary content number, item number, and type number for each headword registered in the vocabulary list. Next, the control unit 11 transmits the acquired dictionary information to the server 2 via the communication unit 16 and requests the transmission of headword display information. When the control unit 21 of server 2 receives dictionary information and a request to send headword display information from user terminal 1, it retrieves headword display information for headwords registered in the search history and headword display information for headwords registered in the word list from dictionary DB 221 based on the received dictionary information, and transmits it to user terminal 1 via communication unit 25. User terminal 1 receives headword display information transmitted from server 2 via communication unit 16.

[0045] In step S9, the control unit 11 generates a second electronic sticky note based on the information obtained based on the two-dimensional code (step S9). If URL information is obtained in step S6, the control unit 11 generates (derives) a second electronic sticky note displaying the linked web page (a thumbnail of the web page) from the URL information. If graph creation information is obtained in step S7, the control unit 11 creates a graph based on the graph creation information and generates (derives) a second electronic sticky note on which the created graph is displayed. If headword display information is obtained in step S8, the control unit 11 generates (derives) a second electronic sticky note displaying the headword list of the electronic dictionary based on the headword display information.

[0046] Next, the control unit 11 links the first electronic sticky note generated in step S2 with the second electronic sticky note generated in step S9 (step S10). Next, the control unit 11 transmits the information of the generated first electronic sticky note and the information of the second electronic sticky note to the server 2 via the communication unit 16, associating them with the user ID of the logged-in user and the notebook name of the notebook 141 (step S11). Server 2 stores the information of the first and second electronic sticky notes received from user terminal 1 in the electronic sticky note DB223, associating it with the user ID and notebook name.

[0047] Next, the control unit 11 links the first electronic sticky note and the second electronic sticky note and displays them in the notebook 141 (step S12). If the second electronic sticky note is one in which a link destination is displayed, the control unit 11 associates the operation tool T1 corresponding to the link destination with the second electronic sticky note and displays it. If the second electronic sticky note is one on which a graph is displayed, the control unit 11 displays the operation tool T2 corresponding to the graph, associating it with the second electronic sticky note. If the second electronic sticky note is one on which the headword list of the electronic dictionary is displayed, the control unit 11 displays the sticky note button T3, which is an operation tool corresponding to the electronic dictionary, associated with the second electronic sticky note. In this embodiment, the sticky note button T3, which is an operation tool corresponding to the electronic dictionary, is displayed on the second electronic sticky note. In other words, the control unit 11 displays operation tools corresponding to the type of teaching material (e.g., links, graphs, electronic dictionaries, etc.) by associating them with the second electronic sticky note.

[0048] Figures 3 to 5 show examples of how Notebook 141 displays the first and second electronic sticky notes. Figure 3 shows an example of how it looks when the acquired image contains a two-dimensional code indicating a URL. Figure 4 shows an example of how it looks when the acquired image contains a two-dimensional code indicating function information. Figure 5 shows an example of how it looks when the acquired image contains a two-dimensional code indicating dictionary information.

[0049] As shown in Figure 3, if the acquired image contains a two-dimensional code C1 indicating a URL, a second electronic sticky note A12 displaying the destination of the URL indicated by the two-dimensional code C1 in the acquired image (for example, a thumbnail of the linked web page) is linked to the first electronic sticky note A11 displaying the acquired image by a linking line L1 and displayed in the notebook 141. In addition, an operation tool T1 including a link button B1 for instructing to open the linked web page is displayed in association with the second electronic sticky note A12. When the link button B1 is pressed, the control unit 11 displays the linked web page on the display unit 14.

[0050] Thus, if the image acquired as the first electronic sticky note contains a two-dimensional code C1 indicating a URL, the second electronic sticky note A12, which displays the destination of the URL indicated by the two-dimensional code C1, will be linked to the first electronic sticky note A11, which displays the image of the medium on which the two-dimensional code C1 was displayed, via a linking line L1. Therefore, it becomes possible to visually record and display the work steps taken when acquiring the destination of the link in an easy-to-understand manner. In the example shown in Figure 3, it becomes possible to visually record and display the work step of acquiring the destination information by reading the two-dimensional code C1 on a plate attached to a tree.

[0051] Furthermore, as shown in Figure 4, if the acquired image contains a two-dimensional code C2 indicating function information, the second electronic sticky note A22, which displays a graph created based on the function information indicated by the two-dimensional code C2 in the acquired image, is linked to the first electronic sticky note A21, which displays the acquired image, by a linking line L2 and displayed in notebook 141. In addition, an operation tool T2 for editing the graph is displayed in association with the second electronic sticky note A22.

[0052] Thus, if the image acquired as the first electronic sticky note contains a two-dimensional code C2 indicating function information, the second electronic sticky note A22, which displays a graph created based on the function information indicated by the two-dimensional code C2, will be linked to the first electronic sticky note A21, which displays the image of the medium on which the two-dimensional code C2 was displayed, via a linking line L2. Therefore, it becomes possible to visually record and display the work steps involved in acquiring the graph in an easy-to-understand manner. In the example shown in Figure 4, it becomes possible to visually record and display the work step of acquiring a graph (graph of a quadratic function) by reading the two-dimensional code C2 displayed on the screen of a scientific calculator.

[0053] Furthermore, as shown in Figure 5, if the acquired image contains a two-dimensional code C3 indicating dictionary information, a second electronic sticky note A32, which displays a list of headwords from an electronic dictionary created based on the dictionary information indicated by the two-dimensional code C3 in the acquired image, is linked to the first electronic sticky note A31, which displays the acquired image, by a linking line L3 and displayed in notebook 141. In addition, a sticky note button T3, which is an operation tool for instructing the user to create a sticky note from the dictionary content of a headword selected from the headword list, is displayed in association with the second electronic sticky note A32.

[0054] Thus, if the image acquired as the first electronic sticky note contains a two-dimensional code C3 indicating dictionary information, the second electronic sticky note A32, which displays a list of headwords created based on the dictionary information indicated by the two-dimensional code C3, will be linked to the first electronic sticky note A31, which displays the image of the medium on which the two-dimensional code C3 was displayed, via a linking line L3. Therefore, it becomes possible to visually record and display the work steps involved in acquiring the list of headwords in an easy-to-understand manner. In the example shown in Figure 5, it becomes possible to visually record and display the work step of acquiring the list of headwords by reading the two-dimensional code C3 displayed on the dictionary screen of the electronic dictionary.

[0055] Next, the control unit 11 determines, based on the input from the operation unit 13, whether or not the operation tool associated with the second electronic sticky note has been operated (step S13). If the control tool is determined to have been operated (step S13; YES), the control unit 11 determines whether the operation performed was pressing the sticky note button T3 (step S14).

[0056] If the control unit determines that the operation performed was pressing the sticky note button T3 (step S14; YES), the control unit 11 generates a third electronic sticky note displaying the explanatory text of the selected headword based on the headword display information of the headword selected from the headword list (step S15), and links the third electronic sticky note to the second electronic sticky note (step S16).

[0057] Next, the control unit 11 transmits the information of the third electronic sticky note, along with the user ID and notebook name of the logged-in user, to the server 2 via the communication unit 16 (step S17). Server 2 stores the information of the third electronic sticky note received from user terminal 1 in the electronic sticky note DB223, associating it with the user ID and notebook name.

[0058] Next, the control unit 11 links the third electronic sticky note to the second electronic sticky note and displays it together with the first electronic sticky note on the notebook 141 of the display unit 14 (step S18), and then terminates the image sticky note display process.

[0059] Figure 6 shows an example of notebook 141 with the first to third electronic sticky notes displayed. Figure 6 shows an example of notebook 141 when the sticky note button T3 shown in Figure 5 is pressed. As shown in Figure 6, when the sticky note button T3 is pressed on the second electronic sticky note A32, the third electronic sticky note A33, which represents the explanatory text for the selected headword (set and despite in Figure 6) from the second electronic sticky note A32, is linked to the second electronic sticky note A32 by the linking line L3 and displayed in notebook 141. Thus, when the sticky note button T3, which is the operation tool corresponding to the second electronic sticky note A32, is pressed, the third electronic sticky note A33 is displayed, showing the explanatory text of the headword selected in the second electronic sticky note A32. Therefore, the user can display the explanatory text of the headword selected in the second electronic sticky note A32 on an electronic sticky note. In addition, since the first electronic sticky note A31 and the second electronic sticky note A32, and the second electronic sticky note A32 and the third electronic sticky note A33 are displayed in a visually linked manner, it is possible to visually display the work steps when obtaining the explanatory text corresponding to the headword in an easy-to-understand manner.

[0060] On the other hand, if in step S14 it is determined that the operation of the operating tool performed was not a press of the sticky note button T3 (step S14; NO), the control unit 11 performs processing according to the operated tool (step S19) and terminates the image sticky note display process.

[0061] On the other hand, if in step S4 it is determined that the two-dimensional code could not be recognized from the acquired image (step S4; NO), the control unit 11 transmits the information of the first electronic sticky note to the server 2 via the communication unit 16 (step S20). Then, the control unit 11 displays the first electronic sticky note on the notebook 141 (step S21) and terminates the image sticky note display process.

[0062] Notebook 141 allows users to modify (e.g., move the position of) electronic sticky notes (1st to 3rd electronic sticky notes) generated by the image sticky note display process, add other electronic sticky notes, and delete electronic sticky notes in response to user operations. Each time an electronic sticky note is modified, added, or deleted in Notebook 141, the control unit 11 sends information about the modification, addition, or deletion to Server 2, associating it with the logged-in user's user ID and the notebook name of Notebook 141, thereby updating the electronic sticky note DB 223. After Notebook 141 is closed, if the operation unit 13 detects a display instruction for Notebook 141, the control unit 11 sends the logged-in user's user ID and the notebook name of Notebook 141 to Server 2, and retrieves information about the electronic sticky notes stored in the electronic sticky note DB 223 from Server 2, associating it with the user ID and notebook name. Then, based on the retrieved electronic sticky note information, the control unit 11 displays the electronic sticky notes in Notebook 141. The user can then view the electronic sticky notes recorded in Notebook 141.

[0063] Furthermore, the generated electronic sticky notes can be saved to a pre-configured save location (folder) for each electronic sticky note. For example, when one of the first to third electronic sticky notes on notebook 141 is selected using the operation unit 13 and the save button 141c is pressed, the control unit 11 saves the data of the selected electronic sticky note to the pre-configured save location. Therefore, individual use of the electronic sticky notes becomes possible, for example, by pasting the generated electronic sticky notes into other notebooks or sending them to a designated submission folder.

[0064] (modified version) In the above embodiment, the case where the acquired image contains one two-dimensional code was described. However, if the acquired image contains multiple two-dimensional codes, the control unit 11 generates a second electronic sticky note corresponding to each two-dimensional code based on each code. The control unit 11 then links each of the multiple second electronic sticky notes to the first electronic sticky note and displays them in the notebook 141.

[0065] Figure 7 shows an example of how Notebook 141 displays when the acquired image contains multiple two-dimensional codes. As an example, Figure 7 shows how Notebook 141 displays when the acquired image contains multiple two-dimensional codes C2 indicating function information, but the information indicated by the two-dimensional codes is not limited to function information. As shown in Figure 7, each of the multiple second electronic sticky notes A22, corresponding to each two-dimensional code C2 contained in the first electronic sticky note A21, is linked and displayed via multiple linking lines L2. The linking lines L2 originate from the vicinity of each two-dimensional code C2 displayed on the first electronic sticky note A21 and connect to the second electronic sticky note A22 displaying the information corresponding to that two-dimensional code C2. This makes it possible to visually display which information was obtained from which two-dimensional code.

[0066] Furthermore, if the acquired image contains multiple two-dimensional codes, the control unit 11 may extract and display each of the recognized two-dimensional codes from the acquired image to create multiple fourth electronic sticky notes from the first electronic sticky note, and then display the multiple fourth electronic sticky notes linked to the first electronic sticky note with a linking line. The control unit 11 may also link each of the fourth electronic sticky notes with a second electronic sticky note displaying information corresponding to the respective two-dimensional code, using a linking line.

[0067] Figure 8 shows another example of how Notebook 141 can be displayed when the acquired image contains multiple two-dimensional codes. As an example, Figure 8 shows how Notebook 141 can be displayed when the acquired image contains multiple two-dimensional codes C2 indicating function information, but the information indicated by the two-dimensional codes is not limited to function information. As shown in Figure 8, multiple fourth electronic sticky notes A24, each displaying a 2D code C2 extracted from the first electronic sticky note A21, are linked to the first electronic sticky note A21 by a linking line L2. Furthermore, each of the multiple fourth electronic sticky notes A24 is linked to a second electronic sticky note A22, each displaying information corresponding to the 2D code C2 displayed on that fourth electronic sticky note A24, also by a linking line L2. This allows for a visually clear display of which information was obtained from which 2D code.

[0068] Furthermore, in the above embodiment, when the captured image acquired by the shooting unit 15 is acquired as the image to be displayed on the electronic sticky note, the image acquired by the shooting unit 15 at the time the shutter button of the operation unit 13 is pressed is acquired as the image to be displayed on the electronic sticky note. However, the method of acquiring the image is not limited to this. For example, the control unit 11 may perform a two-dimensional code recognition process each time an image is acquired by the shooting unit 15, and automatically acquire the image at the time the two-dimensional code is recognized as the image to be displayed on the electronic sticky note. As in the above embodiment, when the image at the time the shutter button of the operation unit 13 is pressed is acquired as the image to be displayed on the electronic sticky note, it becomes possible to display an image with a field of view that suits the user's preference, or an image containing the information the user wants, on the first electronic sticky note. Also, as in this modified example, when the image at the time the two-dimensional code is recognized is automatically acquired as the image to be displayed on the electronic sticky note, it becomes possible to acquire an image including the two-dimensional code without the user having to press the shutter button.

[0069] Furthermore, if the acquired image contains a two-dimensional code, the control unit 11 may display a dialog box on the display unit 14 for the user to select whether or not to generate a second electronic sticky note displaying information corresponding to the two-dimensional code. If the user selects to generate the second electronic sticky note from the dialog box, the control unit 11 may generate and display both the first and second electronic sticky notes. If the user selects not to generate the second electronic sticky note from the dialog box, only the first electronic sticky note may be generated and displayed. This allows the system to control the generation of the second electronic sticky note only when it is necessary.

[0070] As described above, the control unit 11 of the user terminal 1, when it finds that the image acquired as the first electronic sticky note contains a predetermined symbol such as a two-dimensional code, derives a second electronic sticky note displaying information corresponding to the predetermined symbol, visually links the second electronic sticky note to the first electronic sticky note, and displays them together in a predetermined workspace. Therefore, when information is obtained by reading a predetermined symbol such as a two-dimensional code, it becomes possible to visually record the steps involved in obtaining that information in an easy-to-understand manner. In other words, it becomes possible to visually record the step of obtaining information displayed on the second electronic sticky note by reading a predetermined symbol contained in the image of the first electronic sticky note.

[0071] Furthermore, the control unit 11 visually links the second electronic sticky note, derived from the image acquired as the first electronic sticky note, to the first electronic sticky note and displays them together in a predetermined workspace. If the acquired image contains a predetermined symbol, the control unit 11 displays the second electronic sticky note as a display area for teaching materials corresponding to the predetermined symbol. Therefore, when learning materials are acquired by reading a predetermined symbol, it becomes possible to visually record the steps involved in acquiring those materials in an easy-to-understand manner. In other words, it becomes possible to visually record the steps involved in acquiring the learning materials displayed on the second electronic sticky note by reading a predetermined symbol contained in the image of the first electronic sticky note.

[0072] Furthermore, when the control unit 11 displays the second electronic sticky note as the display area for teaching materials, it displays an operation tool corresponding to the type of teaching material associated with the second electronic sticky note. Therefore, users can perform predetermined input operations according to the type of teaching material on the second electronic sticky note.

[0073] Furthermore, when the control unit 11 receives a predetermined input operation via an operation tool corresponding to the second electronic sticky note, it displays the third electronic sticky note, which is visually linked to the second electronic sticky note, together with the first electronic sticky note in the workspace. Therefore, it becomes possible to visually record the work step in which information from the third electronic sticky note is acquired in response to the operation of the operating tool corresponding to the second electronic sticky note.

[0074] Furthermore, the control unit 11 acquires the image captured by the shooting unit 15 at the moment the shutter button is pressed by the user, and uses it as the image for the first electronic sticky note. Therefore, it becomes possible to acquire images with a field of view that suits the user's preference or images containing information that the user wants as the first electronic sticky note.

[0075] Furthermore, the control unit 11 recognizes a predetermined symbol each time an image is acquired by the imaging unit 15, and acquires the image in which the predetermined symbol is recognized as the first electronic sticky note. Therefore, it becomes possible to acquire an image containing a predetermined symbol without the user having to press the shutter button.

[0077] For example, in the above embodiment, Server 2 is equipped with various databases and performs some processing steps such as creating graph creation information and headword display information, as well as saving the generated electronic sticky notes. However, these processes and the saving of electronic sticky notes may be performed on User Terminal 1. Also, some of the functions performed by User Terminal 1 in the above embodiment may be performed by Server 2.
