[0003] Japanese Patent Application Laid-Open No. 2006-92364

[0004] When various font sizes are used on sticky notes or electronic sticky notes, it can be difficult to grasp the overall picture. For example, when multiple electronic sticky notes have different font sizes, opinions with larger font sizes tend to stand out more, which can hinder an impartial overview of all ideas.

[0005] The embodiments of the present invention have been made in consideration of the above-mentioned problems, and are directed to a system in which a plurality of electronic sticky notes are shared, whereby the character sizes of the plurality of electronic sticky notes can be unified and displayed.

[0006] In order to solve the above problem, an information processing device according to an embodiment of the present invention has an acquisition unit that acquires character information of a plurality of electronic sticky notes, a character size determination unit that determines a single display character size for the plurality of electronic sticky notes based on the character information, and a display content determination unit that determines display content to be displayed on the plurality of electronic sticky notes based on the character information and the display character size.

[0007] According to an embodiment of the present invention, in a system in which a plurality of electronic sticky notes are shared, it becomes possible to display the plurality of electronic sticky notes with a unified character size.

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The embodiment described below is merely an example, and the embodiment to which the present invention is applied is not limited to the following embodiment.

[0010] (Summary) Traditionally, sticky notes have been used in idea generation dialogues. Participants write their ideas on the notes, stick them on a whiteboard, and move the notes around to discuss. The size of sticky notes is limited, and the more content they contain, the smaller the text inevitably becomes. The reason for writing ideas on sticky notes is to get an overview of all ideas and organize the discussion as a whole by rearranging sticky notes with similar ideas nearby.

[0011] In recent years, such face-to-face conversations have begun to be conducted over the Internet using remote conference apps and the like. In such systems, sticky note-like items (hereinafter referred to as electronic sticky notes) can be attached to the display of a terminal device such as a personal computer (PC). Text can be written on these electronic sticky notes, which can be used in the same way as sticky notes in the real world. Electronic sticky notes can adjust the size of the characters depending on the number of characters, allowing them to be displayed so that they fit on the sticky note. This is a major advantage of using electronic sticky notes. In electronic conference support systems for such virtual conferences, a technology is known in which participants attach sticky notes on which they have written their opinions to a conference screen shared by the participants (see, for example, Patent Document 1).

[0012] When the font sizes on sticky notes or electronic sticky notes vary, it can be difficult to grasp the overall picture. For example, as in newspaper headlines, headlines are often made more noticeable by increasing the font size. When various font sizes are available on electronic sticky notes, the larger font sizes tend to stand out. Therefore, there is a concern that the different font sizes on electronic sticky notes can be a barrier to discussion. For example, from the perspective of getting an overview of all opinions, if the font sizes of multiple electronic sticky notes on a whiteboard are different, the ideas on the more prominent notes will be emphasized, which can cause problems when getting an impartial overview of all ideas.

[0013] Therefore, in this embodiment, in an electronic sticky note display system in which a plurality of electronic sticky notes are shared, it is possible to display the plurality of electronic sticky notes with a unified character size.

[0014] <System Configuration> Fig. 1 is a diagram (1) showing an example configuration of an electronic sticky note display system according to this embodiment. The electronic sticky note display system 1 includes, for example, a display server 100 and a plurality of terminal devices 10a, 10b, 10c, and 10d that can communicate with the display server 100 via a communication network N. In the following description, the term "terminal device 10" will be used to refer to any of the plurality of terminal devices 10a, 10b, 10c, and 10d. The number of terminal devices 10 shown in Fig. 1 is an example, and may be any number greater than or equal to two.

[0015] (Display Server) The display server (information processing device) 100 is, for example, an information processing device having a computer configuration, or a system including multiple computers. The display server 100 realizes, for example, each functional configuration shown in FIG. 1 by executing a predetermined program on the computer included in the display server 100. In the example of FIG. 1, the display server 100 has each functional configuration, such as a transmission / reception unit 101, an acquisition unit 102, a character size determination unit 103, a display content determination unit 104, an information management unit 105, and a storage unit 106. Note that at least a portion of each of the above functional configurations may be realized by hardware. The display server 100 is an example of an information processing device according to this embodiment.

[0016] The transmitting / receiving unit 101 executes a transmission process for transmitting data to the terminal device 10 via the communication network N, and a reception process for receiving data from the terminal device 10 .

[0017] The acquisition unit 102 executes an acquisition process to acquire character information of a plurality of electronic sticky notes. For example, the acquisition unit 102 acquires character information of a plurality of electronic sticky notes shared by a plurality of terminal devices 10 that can communicate with the display server 100 via the transmission / reception unit 101.

[0018] The character size determination unit 103 executes a character size determination process to determine a single character size (hereinafter referred to as a display character size) for displaying characters on multiple electronic sticky notes shared by participants (or terminal devices 10). For example, the character size determination unit 103 determines a single display character size for multiple electronic sticky notes based on character information acquired by the acquisition unit 102. Note that a method for determining the display character size by the character size determination unit 103 will be described later using multiple examples as examples.

[0019] The display content determination unit 104 executes a display content determination process to determine the display content to be displayed on multiple electronic sticky notes shared by the participants, based on the character information acquired by the acquisition unit 102 and the display character size determined by the character size determination unit 103. For example, when the character information of an electronic sticky note cannot be displayed within the area of ​​the electronic sticky note, the display content determination unit 104 determines a summary of the character information or keywords included in the character information as the display content to be displayed on the electronic sticky note.

[0020] The information management unit 105 executes information management processing to store and manage data of electronic sticky notes, data for converting the number of characters into the character size, etc., which will be described later, in the storage unit 106, etc. The storage unit 106 executes storage processing to store various data, information, setting values, programs, etc.

[0021] (Terminal Device) The terminal device 10 is an information terminal used by the participants, such as a PC, a tablet terminal, or a smartphone. The terminal device 10 executes an application program (hereinafter referred to as an app) for participants that corresponds to the electronic sticky note display system 1, thereby realizing, for example, each functional configuration as shown in Fig. 1. In the example of Fig. 1, the terminal device 10 has a transmitter / receiver 11, a display control unit 12, an operation reception unit 13, a storage unit 14, etc. It should be noted that in Fig. 1, the terminal devices 10b, 10c, and 10d have the same functional configuration as the terminal device 10a.

[0022] The transmission / reception unit 101 performs a transmission process to transmit data to the display server 100 or other terminal devices 10, etc. via the communication network N, and a reception process to receive data from the display server 100 or other terminal devices 10, etc.

[0023] The display control unit 12 executes a display control process for displaying a UI (User Interface) screen of the app on a display device included in the terminal device 10. For example, the display control unit 12 displays a plurality of electronic sticky notes on the UI screen based on display content determined by the display server 100. The operation accepting unit 13 executes an operation acceptance process for accepting input operations by participants on the UI screen displayed by the display control unit 12. The storage unit 106 executes a storage process for storing various data, information, setting values, programs, etc.

[0024] With the above configuration, the multiple terminal devices 10 communicate with the display server 100 via the communication network N, and share and display multiple electronic sticky notes.

[0025] The configuration of the electronic sticky note display system 1 shown in Fig. 1 is an example. For example, the functional components of the display server 100 in Fig. 1 may be distributed among multiple server devices. Furthermore, at least some of the functional components of the display server 100 in Fig. 1 may be included in the terminal device 10.

[0026] For example, in Fig. 1, among the functional components of the display server 100, the acquisition unit 102, the character size determination unit 103, the display content determination unit 104, the information management unit 105, etc. may be included in the terminal device (information processing device) 10 as shown in Fig. 2. Note that in Fig. 2, the terminal devices 10b, 10c, and 10d have the same functional components as the terminal device 10a. In the example of Fig. 2, the terminal device 10 is another example of the information processing device according to this embodiment. In short, the acquisition unit 102, the character size determination unit 103, the display content determination unit 104, the information management unit 105, etc. may be included in any of the devices included in the electronic sticky note display system 1.

[0027] <Processing Flow> Next, the processing flow of the display control method according to this embodiment will be described.

[0028] First Embodiment In a first embodiment, an example will be described in which the display character sizes of a plurality of electronic sticky notes are adjusted to match the electronic sticky note with the smallest character size.

[0029] 3 is a flowchart showing an example of an electronic sticky note display process according to Example 1. Here, the following description will be given assuming that the process in FIG. 3 is executed by the electronic sticky note display system 1 having the configuration shown in FIG.

[0030] In step S301, the operation acceptance unit 13 of the terminal device 10 determines whether or not the end button has been pressed.

[0031] 4 is a diagram (1) illustrating an example of a UI screen according to the first embodiment. This diagram illustrates, for example, an example of a UI screen 400 of a participant app displayed on the terminal device 10a used by participant A in FIG. 1. The display control unit 12 of the terminal device 10a displays, for example, the UI screen 400 as shown in FIG. 4 on a display device or the like provided in the terminal device 10a. Note that the other terminal devices 10b to 10d also display similar UI screens.

[0032] 4 shows an example of a UI screen 400 displayed on a PC window. The UI screen 400 displays, for example, an "Add" button 401, a "Color" button 402, a "Font" button 403, a "Decide" button 404, an End button 405, a display screen 406, and an electronic sticky note 407. The "Add" button 401 is used when adding an electronic sticky note 407 to the display screen 406, for example. The "Color" button 402 is used when changing the color of the electronic sticky note 407, for example. The "Font" button 403 is used when changing the font displayed on the electronic sticky note 407, for example. The "Decide" button 403 is used when confirming input on the electronic sticky note 407, for example. The End button 405 is used when exiting the participant app, for example. The display screen 406 is an area where the electronic sticky note 407 can be attached.

[0033] The operation acceptance unit 13 determines whether or not the end button 405 has been pressed on the UI screen 400. If the end button 405 has not been pressed, the operation acceptance unit 13 shifts the process to step S302. On the other hand, if the end button 405 has been pressed, the operation acceptance unit 13 ends the process of FIG. 3.

[0034] When the process proceeds to step S302, the operation acceptance unit 13 determines whether or not the Add button has been pressed. For example, the operation acceptance unit 13 determines whether or not the "Add" button 401 has been pressed on the UI screen 400. If the Add button has not been pressed, the operation acceptance unit 13 returns the process to step S301. On the other hand, if the Add button has been pressed, the operation acceptance unit 13 proceeds to step S303.

[0035] When the process proceeds to step S303, the display control unit 12 of the terminal device 10 displays an electronic sticky note with no text. For example, participant A clicks the "Add" button 401 with the mouse on the UI screen 400 as shown in Fig. 4, and then clicks the mouse again on the display screen 406. As a result, for example, an electronic sticky note 407 with no text as shown in Fig. 4 is displayed on the display screen 406 of the terminal device 10a.

[0036] Preferably, information on the electronic sticky note 407 displayed by the terminal device 10a is notified to the other terminal devices 10b to 10d, for example, via the display server 100. As a result, the electronic sticky note 407 is also displayed on the display screens 406 of the other terminal devices 10b to 10d.

[0037] In step S304, the display server 100 acquires and stores character information of the electronic sticky note. For example, a participant can input characters by clicking an electronic sticky note 407 with a mouse on a UI screen 400 such as that shown in FIG. 4. The operation acceptance unit 13 of the terminal device 10a transmits character information (text data, etc.) of the input characters to the display server 100 via the transmission / reception unit 11. The acquisition unit 102 of the display server 100 acquires (receives) the character information transmitted by the terminal device 10a via the transmission / reception unit 101.

[0038] The information management unit 105 of the display server 100 manages the character information acquired by the acquisition unit 102 as electronic sticky note data 500, for example, as shown in Fig. 5. For example, the information management unit 105 stores the "sticky note number," the "proposer" which is information about the participant who input the characters, the "sentence" which is the characters (character string) input by the participant, and the "number of characters" of the "sentence" in the electronic sticky note data 500. This electronic sticky note data 500 is stored in, for example, the storage unit 106.

[0039] In step S305, the character size determination unit 103 determines the character size of the electronic sticky note 407 so that the characters (sentences) input by the participants fit on the electronic sticky note 407. For example, the display server 100 stores in advance in the storage unit 106 or the like conversion data 600 for the number of characters and character size as shown in FIG.

[0040] In the example of FIG. 6 , the conversion data 600 indicates the correspondence relationship between the number of characters and the character size when the number of characters ranges from 1 to 44. However, similar conversion data 600 can be prepared to accommodate character counts of 45 or more. The character size determination unit 103 determines the character size corresponding to the number of characters from the number of characters, for example, using the conversion data 600. For example, the sentence "Advertise on the homepage" has 12 characters, so the character size determination unit 103 determines the character size to be 20 pt using the conversion data 600. The information management unit 105 also stores the character size determined by the character size determination unit 103 in the "character size" field of the "text" field in the electronic sticky note data 500, as shown in FIG. 7 .

[0041] The character size determination unit 103 may calculate the character size from the number of characters using, for example, a calculation formula prepared in advance, without being limited to the conversion data.

[0042] In step S306, the character size determination unit 103 determines whether the number of electronic sticky notes is one. If the number of electronic sticky notes is one, the character size determination unit 103 transitions the process to step S309. At this time, the information management unit 105 sets the "display content" to "text" and adds the numerical value of the "character size" to the "display character size" as is, for example, in the electronic sticky note data 500 shown in FIG. 7. On the other hand, if the number of electronic sticky notes is not one, the character size determination unit 103 transitions the process to step S307. In the example of FIG. 4, the number of electronic sticky notes 407 is one, so the character size determination unit 103 transitions the process to step S309.

[0043] In step S309, the display control unit 12 of the terminal device 10 displays the display content on the electronic sticky note, and the process returns to step S301. For example, the information management unit 105 of the display server 100 transmits electronic sticky note data 500 as shown in Fig. 7 to the terminal devices 10a to 10d. The display control unit 12 of the terminal devices 10a to 10d displays electronic sticky notes 407a showing the display content on the display screen 406, for example, as shown in Fig. 8, based on the electronic sticky note data 500 received from the display server 100.

[0044] Next, participant B presses the "Add" button 401 to add an electronic sticky note and input text. In this case, by the processing of steps S301 to S305, the display server 100 acquires text information for the electronic sticky note from the terminal device 10b used by participant B, determines the character size of the electronic sticky note, and updates the electronic sticky note data 500, for example, as shown in FIG.

[0045] For example, since this is the second input, the information management unit 105 sets the "sticky note number" to "2" and the "proposer" to "Participant B," and stores this in the electronic sticky note data 500. The information management unit 105 also stores the text entered by participant B in "text," and stores the number of characters in the "text," "44," in "number of characters." Furthermore, the information management unit 105 stores the character size, "11," determined by the character size determination unit 103, in the "text size" of the "text."

[0046] In step S306, the character size determination unit 103 determines whether the number of electronic sticky notes 407 is 1. In this case, the number of electronic sticky notes 407 is not 1, so the character size determination unit 103 moves the process to step S307.

[0047] In step S307, the character size determination unit 103 determines the display character size for displaying characters on the plurality of electronic sticky notes. In the first embodiment, the character size determination unit 103 determines the smallest character size among the character sizes of the plurality of sticky notes as the display character size for displaying characters on the plurality of electronic sticky notes.

[0048] For example, referring to the electronic sticky note data 500 in Fig. 9, the character size of the electronic sticky note with sticky note number 1 is "20," and the character size of the electronic sticky note with sticky note number 2 is "11." In this case, the character size determination unit 103 determines the smallest character size "11" of the character sizes "20" and "11" of the multiple electronic sticky notes as the display character size for displaying characters on the multiple electronic sticky notes. At this time, the information management unit 105 stores the display character size determined by the character size determination unit 103 in "display character size" of the electronic sticky note data 500, for example, as shown in Fig. 10.

[0049] In step S308, the display content determination unit 104 determines the display content to be displayed on the multiple electronic sticky notes. In the first embodiment, the smallest character size among the character sizes of the multiple sticky notes is determined as the display character size for displaying characters on the multiple electronic sticky notes, so that the "text" of the electronic sticky note data 500 can be displayed on all the electronic sticky notes. Therefore, the display content determination unit 104 determines the display content of the multiple electronic sticky notes to be "text." This indicates that the content of the "text" of the electronic sticky note data 500 is displayed on the electronic sticky notes. At this time, the information management unit 105 stores the display content determined by the display content determination unit 104 in the "display content" of the electronic sticky note data 500, for example, as shown in FIG. 10 .

[0050] In step S309, the display control unit 12 of the terminal device 10 displays the display content on the electronic sticky note, and the process returns to step S301. For example, the information management unit 105 of the display server 100 transmits electronic sticky note data 500 as shown in Fig. 10 to the terminal devices 10a to 10d. The display control unit 12 of the terminal devices 10a to 10d displays electronic sticky notes 407a and 407b showing the display content on the display screen 406, for example, as shown in Fig. 11, based on the electronic sticky note data 500 received from the display server 100.

[0051] Similarly, an example of electronic sticky note data 500 after participants A to D using terminal devices 10a to 10b write ideas on the electronic sticky notes as needed is shown in Figure 12. In the example of Figure 12, the smallest character size among the multiple electronic sticky notes with sticky note numbers 1 to 6 is "11," so the "display character size" is "11." Also, the "display content" for each electronic sticky note is "text."

[0052] For example, the information management unit 105 of the display server 100 transmits electronic sticky note data 500 as shown in Fig. 12 to the terminal devices 10a to 10d. The display control unit 12 of the terminal devices 10a to 10d displays electronic sticky notes 407a to 407f showing the display content on the display screen 406 based on the electronic sticky note data 500 received from the display server 100, for example, as shown in Fig. 13.

[0053] In this way, in Example 1, the display character sizes of multiple electronic sticky notes are displayed according to the electronic sticky note with the smallest character size. Therefore, according to Example 1, in the electronic sticky note display system 1 that shares multiple electronic sticky notes, it becomes possible to display the multiple electronic sticky notes with a unified character size.

[0054] [Example 2] In Example 2, an example will be described in which the display character sizes of a plurality of electronic sticky notes are adjusted to match the electronic sticky note with the largest character size. Note that the flowchart of the electronic sticky note display process according to Example 2 may be the same as the electronic sticky note display process according to Example 1 described in Fig. 3. However, the processing contents of steps S307 and S308 are different from those of Example 1.

[0055] For example, the process in which participant A and participant B add electronic sticky notes and generate the electronic sticky note data 500 shown in Fig. 9 is the same as in Example 1, and therefore will not be described here. After that, in step S306, since the number of electronic sticky notes is not one, the display server 100 executes the processes of steps S307 and S308.

[0056] In step S307, the character size determination unit 103 determines a display character size for displaying characters on the plurality of electronic sticky notes. In the second embodiment, the character size determination unit 103 determines the largest character size among the character sizes of the plurality of sticky notes as the display character size for displaying characters on the plurality of electronic sticky notes.

[0057] 9, the character size of the electronic sticky note with sticky note number 1 is "20," and the character size of the electronic sticky note with sticky note number 2 is "11." In this case, the character size determination unit 103 determines the largest character size "20" of the character sizes "20" and "11" of the electronic sticky notes as the display character size for displaying characters on the electronic sticky notes.

[0058] In Example 2, since the display character size for displaying characters on multiple electronic sticky notes is set to the maximum character size, it may not be possible to display the "text" of all the electronic sticky notes within the area of ​​the electronic sticky notes. Therefore, the display content determination unit 104 has a function to switch the "display content" to an expression with fewer characters than the "text" when the "text" cannot be displayed within the area of ​​the electronic sticky notes.

[0059] For example, when a participant inputs a sentence, the display control unit 12 of the terminal device 10 displays an input field 1400 for inputting the sentence, summary, and keywords on the UI screen 400 as shown in Fig. 14. Furthermore, the operation accepting unit 13 of the terminal device 10 transmits character information including the sentence, summary, keywords, etc. input by the participant in the input field 1400 to the display server 100. The information management unit 105 of the display server 100 stores the sentence, summary, keywords, etc. included in the character information acquired by the acquiring unit 102 in electronic sticky note data 500 as shown in Fig. 15.

[0060] As another example, the information management unit 105 may automatically extract summaries, keywords, etc. from sentences included in the character information acquired by the acquisition unit 102 using generation AI (Artificial Intelligence) or the like.

[0061] 15, the number of characters decreases in the order of "text," "summary," and "keywords." As shown in FIG. 15, the information management unit 105 also adds "number of characters" and "character size" to "summary" and "keywords" in the same way as for "text."

[0062] In step S308, the display content determination unit 104 determines the display content to be displayed on the multiple electronic sticky notes. For example, if the display content determination unit 104 cannot display a "sentence" within the area of ​​the electronic sticky note, it determines a summary of the sentence or keywords as the display content to be displayed on the electronic sticky note.

[0063] 15, since the "text" of the electronic sticky note with sticky note number 2 cannot be displayed within the area of ​​the electronic sticky note, the display content determination unit 104 determines the "display content" of the electronic sticky note with sticky note number 2 to be "summary" or "keywords." In the example of FIG. 15, since "summary" can be displayed with a display character size of 20 pt, the display content determination unit 104 determines the "display content" of the electronic sticky note with sticky note number 2 to be "summary," and stores this in the electronic sticky note data 500. Such a method of determining the display content is stored in advance in, for example, the storage unit 106.

[0064] In step S309, the display control unit 12 of the terminal device 10 displays the display content on the electronic sticky note, and returns the process to step S301. For example, the information management unit 105 of the display server 100 transmits electronic sticky note data 500 as shown in Fig. 15 to the terminal devices 10a to 10d. Alternatively, the information management unit 105 may transmit only the data necessary for displaying the electronic sticky note from the electronic sticky note data 500 as shown in Fig. 15 to the terminal devices 10a to 10d.

[0065] The display control unit 12 of the terminal devices 10a to 10d displays electronic sticky notes 407a and 407b showing the display content on the display screen 406, for example, as shown in Figure 16, based on the electronic sticky note data 500 received from the display server 100.

[0066] Similarly, an example of electronic sticky note data 500 after participants A to D using terminal devices 10a to 10b write ideas on the electronic sticky notes as needed is shown in Fig. 17. In the example of Fig. 17, among the character sizes of the "text" on multiple electronic sticky notes numbered 1 to 6, the largest character size is "28" for sticky note number 3, so the "display character size" is "28".

[0067] In the example of Figure 17, the characters are made smaller in the order of "text," "summary," and "keywords," so the amount of information lost in the "summary" and "keywords" compared to the original "text." Therefore, if possible, it is better to select display content that is close to the original "text." Therefore, in the example of Figure 17, the electronic sticky note with sticky note number 3 has the "display content" set to "text," the electronic sticky notes with sticky note numbers 4 and 5 have the "display content" set to "summary," and the electronic sticky notes with sticky note numbers 1, 2, and 6 have the "display content" set to "keywords." Furthermore, because the number of characters in the text on the electronic sticky note with sticky note number 3 is sufficiently small, the text and the summary contain the same wording.

[0068] For example, the information management unit 105 of the display server 100 transmits electronic sticky note data 500 as shown in Fig. 17 to the terminal devices 10a to 10d. Alternatively, the information management unit 105 may transmit only the data necessary for displaying the electronic sticky note from the electronic sticky note data 500 as shown in Fig. 17 to the terminal devices 10a to 10d.

[0069] The display control unit 12 of the terminal devices 10a to 10d displays electronic sticky notes 407a to 407f showing the display content on the display screen 406, for example, as shown in Figure 18, based on the electronic sticky note data 500 received from the display server 100.

[0070] Note that one method for reducing the number of characters in the "text" is to extract only a certain number of characters. For example, in FIG. 15 , since the number of characters in the electronic sticky note with sticky note number 1 is 12, the display content determination unit 104 may also set the number of characters in the electronic sticky note with sticky note number 2 to the same 12 characters. For example, the display content determination unit 104 may select the first 11 characters of the "text" in the electronic sticky note with sticky note number 2, add "...", and determine "Poster at the festival venue..." as the display content. In this case, the key word "QR Code (registered trademark)" is not included, which poses a problem in that the information is not conveyed; however, in addition to setting a summary or keywords, appropriate parts may be extracted.

[0071] In this way, in Example 2, the display character sizes of multiple electronic sticky notes are displayed according to the electronic sticky note with the largest character size. Therefore, according to Example 2, in the electronic sticky note display system 1 that shares multiple electronic sticky notes, it becomes possible to display multiple electronic sticky notes with a unified character size.

[0072] [Example 3] In Example 3, an example will be described in which the display character size of a plurality of electronic sticky notes is determined based on the average value of the character sizes of the plurality of electronic sticky notes. Note that the flowchart of the electronic sticky note display process according to Example 3 may be the same as the electronic sticky note display process according to Example 1 described in Fig. 3. However, the processing contents of steps S307 and S308 are different from those of Example 1.

[0073] For example, the process in which participant A and participant B add electronic sticky notes and generate the electronic sticky note data 500 shown in Fig. 9 is the same as in Example 1, and therefore will not be described here. After that, in step S306, since the number of electronic sticky notes is not one, the display server 100 executes the processes of steps S307 and S308.

[0074] In step S307, the character size determination unit 103 determines a display character size for displaying characters on a plurality of electronic sticky notes. In the third embodiment, the character size determination unit 103 determines a display character size for displaying characters on a plurality of electronic sticky notes based on an average value of the character sizes of the plurality of sticky notes.

[0075] 9 , the character size of "Text" on the electronic sticky note with sticky note number 1 is "20," and the character size of "Text" on the electronic sticky note with sticky note number 2 is "11." In this case, the character size determination unit 103 calculates the average value of the character sizes "20" and "11" on the multiple electronic sticky notes, and determines the calculated average value "15.5" as the display character size for displaying text on the multiple electronic sticky notes. Alternatively, the character size determination unit 103 may determine another character size (e.g., "15" or "16") close to the calculated average value "15.5" as the display character size for displaying text on the multiple electronic sticky notes.

[0076] In step S308, the display content determination unit 104 determines the display content to be displayed on the multiple electronic sticky notes, in the same manner as in Example 2. Furthermore, the information management unit 105 stores the display character size determined by the character size determination unit 103 and the display content determined by the display content determination unit 104 in electronic sticky note data 500, for example, as shown in Fig. 19. In the example of Fig. 19, the electronic sticky note with sticky note number 1 has the "display content" set to "text," while the electronic sticky note with sticky note number 2 has the "display content" set to "summary," which has a character size of 20, because attempting to display "text" would require a character size of 11, which cannot be displayed at a character size of 15.5.

[0077] In step S309, the display control unit 12 of the terminal device 10 displays the display content on the electronic sticky note, and returns the process to step S301. For example, the information management unit 105 of the display server 100 transmits electronic sticky note data 500 as shown in Fig. 19 to the terminal devices 10a to 10d. Alternatively, the information management unit 105 may transmit only the data necessary for displaying the electronic sticky note from the electronic sticky note data 500 as shown in Fig. 19 to the terminal devices 10a to 10d.

[0078] The display control unit 12 of the terminal devices 10a to 10d displays electronic sticky notes 407a and 407b showing the display content on the display screen 406, for example, as shown in Figure 20, based on the electronic sticky note data 500 received from the display server 100.

[0079] Similarly, FIG. 21 shows an example of electronic sticky note data 500 after participants A-D using terminal devices 10a-10b have written ideas on the electronic sticky notes as needed. In the example of FIG. 21, the character sizes of the "text" on the electronic sticky notes with sticky note numbers 1-6 are 20, 11, 28, 14, 20, and 20, respectively, resulting in an average value of 18.8333... In this case, the character size determination unit 103, for example, rounds down to the second decimal place and determines the "display character size" to be "18.8." This method of determining the display character size is stored in advance, for example, in the storage unit 106. Note that in the example of FIG. 21, since it is preferable to select display content that is as close to the original "text" as possible, the "display content" of the electronic sticky notes with sticky note numbers 1, 3, 5, and 6 is set to "text," while the "display content" of the electronic sticky notes with sticky note numbers 2 and 4 is set to "summary."

[0080] For example, the information management unit 105 of the display server 100 transmits electronic sticky note data 500 as shown in Fig. 21 to the terminal devices 10a to 10d. Alternatively, the information management unit 105 may transmit only the data necessary for displaying the electronic sticky note from the electronic sticky note data 500 as shown in Fig. 21 to the terminal devices 10a to 10d.

[0081] The display control unit 12 of the terminal devices 10a to 10d displays electronic sticky notes 407a to 407f showing the display content on the display screen 406, for example, as shown in Figure 22, based on the electronic sticky note data 500 received from the display server 100.

[0082] In this way, in Example 2, the display character size of a plurality of electronic sticky notes is determined based on the average value of the character sizes of the plurality of electronic sticky notes. Therefore, according to Example 3, in the electronic sticky note display system 1 that shares a plurality of electronic sticky notes, it becomes possible to display the plurality of electronic sticky notes with a unified character size.

[0083] [Example 4] In Example 4, an example will be described in which a participant sets the display character size of multiple electronic sticky notes. The flowchart of the electronic sticky note display process according to Example 4 may be the same as the electronic sticky note display process according to Example 1 described in Fig. 3. However, the UI screen 400 displayed by the terminal device 10 has a setting field 2300 for setting the display character size of multiple electronic sticky notes, as shown in Fig. 23, for example.

[0084] 23 , a participant (user) can set the display character size of multiple electronic sticky notes by moving a slider 2301. However, this is just one example, and the setting field 2300 for setting the display character size of multiple electronic sticky notes may be configured to set the display character size of multiple electronic sticky notes by, for example, entering a numerical value or using a drop-down list.

[0085] Fig. 23 shows an example of the UI screen 400 when the display character size is set to 18.8 pt. Furthermore, when a participant changes the display character size to 11 pt, the display control unit 12 of the terminal device 10 displays, for example, multiple electronic sticky notes 407a to 407f as shown in Fig. 13. Similarly, when a participant changes the display character size to 28 pt, the display control unit 12 of the terminal device 10 displays, for example, multiple electronic sticky notes 407a to 407f as shown in Fig. 18.

[0086] In this way, in the fourth embodiment, participants (users) can freely set the display character size of a plurality of electronic sticky notes.

[0087] In the above example, there are four participants in the dialogue, but the settings may be the same for all participants in the electronic sticky note display system 1. For example, the electronic sticky note display system 1 may be configured so that when participant A changes the display character size setting, the display character size settings of the other participants B, C, and D are also changed at the same time.

[0088] Alternatively, the electronic sticky note display system 1 may prepare electronic sticky note data 500 such as those shown in FIGS. 17 and 21 for each participant, so that the display character size can be determined for each participant.

[0089] <Hardware Configuration> The display server 100 and the terminal device 10 according to this embodiment have, for example, the hardware configuration of a computer 2400 as shown in Fig. 24. Alternatively, the display server 100 is realized by a plurality of computers 2400. Note that the computers are not limited to physical machines and may be, for example, virtual machines on the cloud.

[0090] Fig. 24 is a diagram showing an example of the hardware configuration of a computer. In the example of Fig. 24, a computer 2400 includes a drive device 1000, an auxiliary storage device 1002, a memory device 1003, a CPU 1004, an interface device 1005, a display device 1006, an input device 1007, and an output device 1008, which are all interconnected by a bus B. The computer 2400 may further include a GPU (Graphics Processing Unit) or the like.

[0091] A program for implementing processing on the computer 2400 is provided by a recording medium 1001, such as a CD-ROM or a memory card. When the recording medium 1001 storing the program is set in the drive device 1000, the program is installed from the recording medium 1001 to the auxiliary storage device 1002 via the drive device 1000. However, the program does not necessarily have to be installed from the recording medium 1001, but may be downloaded from another computer via a network. The auxiliary storage device 1002 stores the installed program as well as necessary files, data, etc.

[0092] The memory device 1003 reads and stores the program from the auxiliary storage device 1002 when an instruction to start the program is received. The CPU 1004 realizes functions related to the display server 100 in accordance with the program stored in the memory device 1003. The interface device 1005 is used as an interface for connecting to a communication network N, etc. The display device 1006 displays a GUI (Graphical User Interface) or the like according to the program. The input device 1007 is composed of a keyboard, mouse, buttons, and / or a touch panel, etc., and is used to input various operation instructions. The output device 1008 outputs the results of calculations.

[0093] The CPU 1004 may be a processor such as a DSP (Digital Signal Processor), a PLD (Programmable Logic Device), or an FPGA.

[0094] <Effects of the Embodiment> According to the present embodiment, in the electronic sticky note display system 1 that shares a plurality of electronic sticky notes, it becomes possible to unify the display character sizes of the plurality of electronic sticky notes.

[0095] Furthermore, in the electronic sticky note display system 1 according to the present embodiment, if the text entered by a participant cannot be displayed within the area of ​​the electronic sticky note, a summary of the text, keywords, etc. can be displayed on the electronic sticky note. Therefore, even if the display character size is unified, it is possible to prevent the display content of the electronic sticky note from becoming difficult to understand.
