[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 text size on sticky notes or electronic sticky notes is small, it can be difficult to read. When using sticky notes in the real world, there is little difficulty in reading the text, such as by getting close to the whiteboard on which the sticky notes are attached. On the other hand, when using electronic sticky notes, enlarging the screen can sometimes make the text easier to read, but enlarging the screen has the disadvantage that the entire image becomes obscured, requiring frequent zooming. In other words, because the screen size is generally smaller than that of a whiteboard, the text can be difficult to read depending on the text size.

[0013] Furthermore, even if the character size (hereinafter referred to as "set character size") is set to the same point size, the actual character size (hereinafter referred to as "display character size") will vary depending on the resolution of the display used by the user. Also, the display character size will vary depending on the display magnification. For example, in a system in which multiple terminal devices share electronic sticky notes, the readability of the contents written on the electronic sticky notes may differ even if the set character size is the same.

[0014] Therefore, in this embodiment, in a system in which multiple terminal devices share electronic sticky notes, the display character size is adjusted to be appropriate, making the contents of the electronic sticky notes displayed by each of the multiple terminal devices easier to read.

[0015] <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.

[0016] (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 provided 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. In the example of FIG. 1, the display server 100 is an information processing device according to this embodiment.

[0017] 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 .

[0018] 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. This character information includes text written on the electronic sticky notes by participants using the terminal devices 10. The acquisition unit 102 also acquires operation information transmitted by each terminal device 10 (for example, information such as an operation to add an electronic sticky note, an operation to set the magnification ratio, and an operation to set setting information).

[0019] The character size determination unit 103 executes a character size determination process to determine the display character size for displaying characters on a plurality of electronic sticky notes displayed by each of the terminal devices 10. For example, the character size determination unit 103 determines the display character size for the plurality of electronic sticky notes displayed by the terminal device 10 based on information about the terminal device 10 and / or information about participants (users) using the terminal device 10, and character information acquired by the acquisition unit 102.

[0020] Preferably, the character size determination unit 103 determines the display character size of the multiple electronic sticky notes displayed by the terminal device 10 to a character size that can be read by a user using the terminal device 10 (hereinafter referred to as readable character size).

[0021] Preferably, the character size determination unit 103 determines the display character size of the multiple electronic sticky notes displayed by the terminal device 10 to be the smallest display character size among the readable character sizes that can be read by the user of the terminal device 10. When there are a large number of characters, there is a risk that the characters will not all fit on the sticky note, so it is preferable to use the smallest display character size so that the characters can be displayed within the sticky note area. Note that a method for determining the display character size by the character size determination unit 103 will be described later using an example.

[0022] The display content determination unit 104 determines the display content of the multiple electronic sticky notes to be displayed on each of the terminal devices 10 based on the character information acquired by the acquisition unit 102 and the display character size determined by the character size determination unit 103 .

[0023] Preferably, when the text contained in the character information acquired by the acquisition unit 102 cannot be displayed within the area of ​​the electronic sticky note, the display content determination unit 104 determines a summary or keywords of the text as the display content to be displayed on the electronic sticky note.

[0024] The information management unit 105 executes information management processing for storing and managing information such as electronic sticky note data, conversion data, display condition data, and readable character size, which will be described later, in the storage unit 106, etc. The storage unit 106 executes storage processing for storing various data, information, setting values, programs, etc. Note that the storage unit 106 may be provided outside the display server 100.

[0025] (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.

[0026] 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.

[0027] The display control unit 12 executes a display control process for displaying a UI (User Interface) screen of the application on a display device included in the terminal device 10. The operation reception unit 13 executes operation reception for receiving, for example, 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, and the like.

[0028] With the above configuration, each terminal device 10 used by a participant communicates with the display server 100 via the communication network N to share and display a plurality of electronic sticky notes.

[0029] 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.

[0030] 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 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 described in Fig. 1. In the example of Fig. 2, the terminal device (information processing device) 10 is the information processing device according to this embodiment.

[0031] <Processing Flow> Next, the processing flow of the display control method according to this embodiment will be described.

[0032] 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 an electronic sticky note display system 1 having the configuration shown in FIG.

[0033] In step S301, the operation acceptance unit 13 of the terminal device 10 determines whether or not the end button has been pressed.

[0034] 4 is a diagram illustrating an example of a UI screen according to Example 1. This diagram illustrates an example of a UI screen 400 of a participant app displayed by the terminal device 10. The display control unit 12 of the terminal device 10 causes, for example, a display device or the like provided in the terminal device 10 to display the UI screen 400 as illustrated in FIG.

[0035] 4 shows an example of a UI screen 400 displayed on a PC window. This UI screen 400 displays, for example, an "Add" button 401, a "Color" button 402, a "Font" button 403, a setting area 404, a "Decide" button 405, an end button 406, a display area 407, and an electronic sticky note 408. The "Add" button 401 is used to add an electronic sticky note 408 to the display area 407, for example. The "Color" button 402 is used to change the color of the electronic sticky note 408, for example. The "Font" button 403 is used to change the font displayed on the electronic sticky note 408, for example. The setting area 404 is used to set the magnification ratio of the display area 407, for example. The "Decide" button 403 is used to confirm input on the electronic sticky note 408, for example. The end button 406 is used to close the participant app, for example. The display area 407 is an area where the electronic sticky note 408 is displayed.

[0036] 3, the operation acceptance unit 13 determines whether or not the end button 406 has been pressed on the UI screen 400. If the end button 406 has not been pressed, the operation acceptance unit 13 shifts the process to step S302. On the other hand, if the end button 406 has been pressed, the operation acceptance unit 13 terminates the process of FIG. 3.

[0037] In step S302, the operation accepting unit 13 determines whether the zoom scale has been operated. For example, the operation accepting unit 13 determines whether the zoom scale 409 displayed in the setting area 404 on the UI screen 400 has been operated. If the zoom scale 409 has been operated, the operation accepting unit 13 proceeds to step S307. On the other hand, if the zoom scale 409 has not been operated, the operation accepting unit 13 proceeds to step S303.

[0038] When the process proceeds to step S303, 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 S304.

[0039] When the process proceeds to step S304, the display control unit 12 of the terminal device 10a displays an electronic sticky note with no text. Note that the area of ​​the electronic sticky note is set in advance. For example, participant 1 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 area 407. As a result, an electronic sticky note 408 with no text, as shown in FIG. 4, is displayed on the display area 407 of the terminal device 10a. Note that information about the electronic sticky note 408 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 408 is also displayed on the display area 407 of the other terminal devices 10b to 10d.

[0040] In step S305, the display server 100 acquires and stores the character information of the electronic sticky note. For example, participant 1 using terminal device 10a can input characters by clicking an electronic sticky note 408 with a mouse on a UI screen 400 such as that shown in FIG. 4. The operation acceptance unit 13 of 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 terminal device 10a via the transmission / reception unit 101.

[0041] 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.

[0042] In step S306, the character size determination unit 103 determines the set character size of the electronic sticky note 408 so that the characters (sentences) input by the participants fit on the electronic sticky note 408. 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 the set character size as shown in FIG.

[0043] In the example of FIG. 6 , the conversion data 600 shows the correspondence between the number of characters and the set character size when the number of characters is 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, for example, uses the conversion data 600 to determine the set character size corresponding to the number of characters from the number of characters. For example, since the sentence "Advertise on the homepage" has 12 characters, the character size determination unit 103 determines the set character size to 20 pt from the conversion data. Here, because blank spaces on the electronic sticky note reduce efficiency, the largest set character size that can be displayed on the electronic sticky note is adopted. The information management unit 105 also stores the set character size determined by the character size determination unit 103 in the "character size" field of the electronic sticky note data 500.

[0044] The character size determination unit 103 may calculate the set character size from the number of characters using, for example, a calculation formula prepared in advance, without being limited to the conversion data.

[0045] In step S307, the electronic sticky note display system 1 executes, for example, a process of determining the character size as shown in FIG.

[0046] 7 is a flowchart showing an example of a process for determining a character size according to Example 1. This process shows an example of a process for determining a character size executed by the electronic sticky note display system 1 in step S307 in FIG.

[0047] In step S701, the character size determination unit 103 initializes a counter i to one.

[0048] In step S702, the character size determination unit 103 determines whether the display character size of the electronic sticky note is within the visible range of participant i. For example, the display server 100 stores data such as the resolution of the display used by each participant, the relative resolution of the display, and the magnification rate of the display screen as display condition data 800 in the storage unit 106, as shown in FIG. 8. The relative resolution of the display, the magnification rate, and the like are acquired, for example, from an app executed by the terminal device 10 used by each participant. The display condition data 800 is an example of information about the terminal device.

[0049] Furthermore, the display server 100 stores the minimum readable character size of each participant in the storage unit 106, for example, as a readable character size 900, as shown in FIG. 9 . This minimum readable character size may be set by the user from an adjustment screen or setting screen of the app, for example, when each participant installs the app on the terminal device 10. Also, if the minimum readable character size has not been adjusted (or set), the minimum readable character size of the participant may be set to a default value. Note that the readable character size 900 is an example of information of the user who uses the terminal device.

[0050] Here, the minimum readable character size is defined as the smallest readable display character size. The display resolution shown here is relative. The number of dots per inch (relative resolution) is determined by the number of horizontal and vertical dots on the screen (absolute resolution) and the display size. Furthermore, the display character size is determined by the display resolution and the specified character size.

[0051] For example, according to the display condition data 800 in FIG. 8 , the relative resolution of participant 1's display is 200 dpi (dots per inch), meaning that participant 1's display has a relative resolution of 200 dots per inch. Assume that a set character size of 20 points (dots) is specified for this display. For example, this 20-point character size refers to the character height. In this case, since the magnification factor is 1, the display character size is calculated as magnification factor × character size / relative resolution, or 1 × 20 (dots) / 200 (dpi) = 0.1 (inch).

[0052] 9, the minimum readable character size for participant 1 is 0.1 inches. In this case, the character size determination unit 103 determines that the character size of the electronic sticky note is within the visible range of participant 1 (0.1 inches or more), because the actual character size of the electronic sticky note is within the visible range of participant 1.

[0053] 7, the description of the flowchart in FIG. 7 will be continued. If the character size of the electronic sticky note is within the visible range of participant i, the character size determination unit 103 shifts the process to step S703. On the other hand, if the character size of the electronic sticky note is not within the visible range of participant i, the character size determination unit 103 shifts the process to step S704.

[0054] In step S703, the character size determination unit 103 determines the current display character size as the display character size.

[0055] On the other hand, when the process proceeds to step S704, the character size determination unit 103 calculates the display character size. For example, the character size determination unit 103 calculates the display character size so that it is equal to or larger than the minimum readable character size for participant i. Preferably, the character size determination unit 103 determines the display character size so that the white space on the electronic sticky note is minimized. These determination methods are stored in advance in, for example, the storage unit 106.

[0056] In step S705, the information management unit 105 updates the electronic sticky note data 500 of participant i. For example, if the character size determination unit 103 determines the display character size of sticky note number 1 for participant 1 to be 0.1 inches, the information management unit 105 stores 0.1 in "display character size 1" of the electronic sticky note data 500, as shown in FIG. 10. Display character size 1 is the display character size for participant 1, and in this example, sticky note number 1 on the electronic sticky note with sticky note number 1 is set to 0.1. The information management unit 105 stores "text" in "display content 1" of the electronic sticky note data 500. This indicates that the content of "text" in the electronic sticky note data 500 is displayed on the electronic sticky note.

[0057] In step S706, the character size determination unit 103 determines whether the value of counter i is equal to or greater than the number N of participants (four in the example of FIG. 1). If the value of i is equal to or greater than N, the character size determination unit 103 ends the process of FIG. 7 and returns the process to step S308 of FIG. 3. On the other hand, if the value of i is less than N, the character size determination unit 103 proceeds to step S707.

[0058] In step S707, the character size determination unit 103 increments the counter i by 1 and executes the processes from step S702 onwards again.

[0059] Through the above process, the character size determination unit 103 can determine the display character size of the other participants 2 to 4.

[0060] For example, when the value of counter i is 2, the character size determination unit 103 determines whether the display character size of the electronic sticky note is within the visible range of participant 2.

[0061] For example, from the display condition data 800, the relative resolution of participant 2's display is 400 dpi (400 dots per inch). Furthermore, since the magnification is 1, the display character size is 1×20 (dots) / 400 (dpi)=0.05 (inches). Furthermore, from the readable character size 900, the minimum readable size for participant 2 is 0.05 inches, so the character size determination unit 103 determines that the character size of the electronic sticky note is within participant 2's visible range. Accordingly, the character size determination unit 103 determines the display character size for participant 2 to be 0.05 inches. The information management unit 105 stores the minimum character size determined by the character size determination unit 103 in "display character size 2" of the electronic sticky note data 500.

[0062] Similarly, when the value of counter i is 3, the character size determination unit 103 determines whether the character size of the electronic sticky note is within the visible range of participant 3 or not.

[0063] For example, the display condition data 800 indicates that the relative resolution of participant 3's display is 160 dpi (160 dots per inch). Furthermore, since the magnification is 1, the actual character size is 1×20 (dots) / 160 (dpi)=0.125 (inches). Furthermore, the readable character size 900 indicates that the minimum readable size for participant 3 is 0.08 inches, so the character size determination unit 103 determines that the character size of the electronic sticky note is within the visible range of participant 2. Consequently, the character size determination unit 103 determines the display character size for participant 3 to be 0.125 inches. The information management unit 105 stores the minimum character size determined by the character size determination unit 103 in "display character size 3" of the electronic sticky note data 500.

[0064] Similarly, when the value of counter i is 4, the character size determination unit 103 determines whether the character size of the electronic sticky note is within the visible range of participant 4 or not.

[0065] For example, the display condition data 800 indicates that the relative resolution of participant 4's display is 250 dpi (250 dots per inch). Furthermore, since the magnification is 1, the actual character size is 1×20 (dots) / 250 (dpi)=0.08 (inches). Furthermore, the readable character size 900 indicates that the minimum readable size for participant 4 is 0.02 inches, so the character size determination unit 103 determines that the character size of the electronic sticky note is within the visible range of participant 2. Consequently, the character size determination unit 103 determines the display character size for participant 4 to be 0.08 inches. The information management unit 105 stores the minimum character size determined by the character size determination unit 103 in "display character size 4" of the electronic sticky note data 500.

[0066] When the processing in FIG. 7 is completed, in step S308 in FIG. 3, the display content determination unit 104 determines the display content to be displayed on the electronic sticky note by each terminal device 10 based on the display character size determined by the character size determination unit 103.

[0067] For example, in the electronic sticky note data 500 shown in FIG. 11 , if "text" can be displayed within the electronic sticky note area with "display character size 1," the display content determination unit 104 determines "display content 1," which is the display content of the terminal device 10a used by participant 1, to be "text." On the other hand, in the electronic sticky note data 500 shown in FIG. 11 , if "text" cannot be displayed within the electronic sticky note area with "display character size 1," the display content determination unit 104 determines "display content 1" to be "summary" or "keywords." Note that "summary" is a summary sentence that summarizes "text," and "keywords" are keywords included in "text" or "summary." Note that summaries and keywords will be described in detail in Example 2.

[0068] 11 , the display content determination unit 104 determines "display content 2," which is the display content of the terminal device 10b used by participant 2, from the "text" and "display character size 2" of the electronic sticky note data 500. Also, the display content determination unit 104 determines "display content 3," which is the display content of the terminal device 10c used by participant 3, from the "text" and "display character size 3" of the electronic sticky note data 500. Furthermore, the display content determination unit 104 determines "display content 4," which is the display content of the terminal device 10d used by participant 4, from the "text" and "display character size 4" of the electronic sticky note data 500.

[0069] The information management unit 105 stores the display content determined in step S308 in the electronic sticky note data 500. As a result, the display server 100 can obtain, for example, the electronic sticky note data 500 as shown in Fig. 11. In the example of Fig. 11, participants 1 to 4 are able to display "text" within the electronic sticky note area, so "display content 1" to "display content 4" are set to "text."

[0070] In step S309, the display control unit 12 of each terminal device 10 displays the display content determined by the display server 100 on the electronic sticky note. For example, the information management unit 105 of the display server 100 transmits electronic sticky note data 500 as shown in FIG. 11 to the terminal devices 10a to 10d. The display control units 12 of the terminal devices 10a to 10d display the display content determined by the display content determination unit 104 on the electronic sticky note with sticky note number 1 based on the electronic sticky note data 500 received from the display server 100. Note that the information management unit 105 may transmit to each terminal device 10 only the data necessary for each terminal device 10 to display the electronic sticky note from the electronic sticky note data 500 as shown in FIG. 11.

[0071] For example, as shown in FIG. 12, the display control unit 12 of the terminal device 10a displays the text set to "Text" on the electronic sticky note 408a with sticky note number 1 displayed on the UI screen 1200 of participant 1, with a display character size of 0.1 inches set to "Display character size 1."

[0072] 13, the display control unit 12 of the terminal device 10b displays the text set in "Text" in a display character size of 0.05 inches, which is set as "Display Character Size 2," on the electronic sticky note 408a with sticky note number 1 displayed on the UI screen 1300 of participant 2. Similarly, the terminal devices 10c and 10d display the display content determined by the display content determination unit 104 on the electronic sticky note with sticky note number 1 displayed on the UI screens of participants 3 and 4.

[0073] The electronic sticky note display system 1 repeatedly executes the process of Fig. 3 until the end button is pressed, thereby enabling each participant to add any electronic sticky note and share it with other participants.

[0074] Thus, according to Example 1, in a system in which multiple terminal devices 10 share electronic sticky notes, the display contents of the electronic sticky notes displayed by each of the multiple terminal devices 10 can be displayed as large as possible, at or above the minimum readable character size.

[0075] In Example 2, an example of changing the magnification ratio of the display area of ​​the UI screen will be described. Assume that participants 1 to 4 perform the processes described in Figures 3 and 7, and as a result, for example, electronic sticky note data 500 as shown in Figure 14 is obtained.

[0076] In this case, the display character size 1 of the electronic sticky note with sticky note number 2 for participant 1 is 0.055, which is smaller than the minimum readable character size of 0.1 for participant 1. The display character size 2 of the electronic sticky note with sticky note number 2 is 0.275, which is smaller than the minimum readable character size of 0.05 for participant 2. The display character size 3 of the electronic sticky note with sticky note number 2 is 0.06875, which is smaller than the minimum readable character size of 0.08 for participant 3. The display character size 4 of the electronic sticky note with sticky note number 2 is 0.044, which exceeds the minimum readable character size of 0.02 for participant 4. Therefore, the display character size of the electronic sticky note with sticky note number 2 is smaller than the minimum readable character size of participants 1, 2, and 3. Furthermore, the character size of the electronic sticky note with sticky note number 4 is smaller than the minimum readable character size of participants 1 and 2. To solve this problem, even if you want to make the text larger, for example, if you increase the text size of sticky notes number 2 and 4, the "text" cannot be displayed within the area of ​​the electronic sticky note.

[0077] Therefore, the display content determination unit 104 according to this embodiment has a function of switching the "display content" to an expression with fewer characters than the "sentence" when the "sentence" cannot be displayed within the area of ​​the electronic sticky note.

[0078] For example, when a participant inputs a sentence, the display control unit 12 of the terminal device 10 displays an input field 1501 for inputting the sentence, summary, and / or keywords on a UI screen 1500 as shown in Fig. 15. 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. 16, for example.

[0079] 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.

[0080] 16, the number of characters decreases in the order of sentence, summary, and keywords, but it is sufficient to switch to the largest number of characters that exceeds the minimum readable character size. Note that in the electronic sticky note with sticky number 3, the number of characters in the sentence is sufficiently small, so the sentence and summary contain the same wording.

[0081] 14 , there was a problem in that the display of the electronic sticky note with sticky note number 2 was below the minimum readable character size for participants 1, 2, and 3. There was also a problem in that the display of the electronic sticky note with sticky note number 4 was below the minimum readable character size for participants 1 and 2.

[0082] In the example of Figure 14, the electronic sticky note with sticky note number 2 has a display character size 1 of 0.055 for "Text" for participant 1, which is below the minimum readable character size of 0.1 for participant 1. On the other hand, in the example of Figure 16, the set character size 1 for "Summary" on the electronic sticky note with sticky note number 2 is 20 points, which is 1 x 20 (dots) / 200 (dpi) = 0.1 (inches), and the display character size 1 is 0.1, which is above the minimum readable character size of 0.1 for participant 1. Therefore, "Summary" is set as display content 1.

[0083] In the example of Figure 14, the display character size 2 of "Text" for participant 2 on the electronic sticky note with sticky note number 2 is 0.275, which is below the minimum readable character size of 0.05 for participant 2. On the other hand, in the example of Figure 16, the display character size 2 of "Summary" is calculated in the same way as for participant 1, at 1 x 24 (dots) / 400 (dpi) = 0.05 (inches), which is above the minimum readable character size of 0.05 for participant 2. Therefore, "Summary" is set as display content 2.

[0084] In the example of Figure 14, the display character size 3 of the electronic sticky note with sticky note number 2 is 0.06875, which is smaller than the minimum readable character size of 0.08 for participant 3. On the other hand, in the example of Figure 16, the display character size 3 of "Summary" is calculated in the same way as for participant 1, at 1 x 24 (dots) / 160 (dpi) = 0.15 (inches), which is larger than the minimum readable character size of 0.08 for participant 3. Therefore, "Summary" is set as display content 3.

[0085] 14, the display character size 1 of the electronic sticky note with sticky note number 4 is 0.07, which is smaller than the minimum readable character size of 0.1 for participant 1. On the other hand, in the example of FIG. 16, the display character size 1 of "Summary" is 1×24 (dots) / 200 (dpi) = 0.14 (inches), which is larger than the minimum readable character size of 0.1 for participant 1. Therefore, "Summary" is set as display content 2.

[0086] Furthermore, in the example of Figure 14, the display character size 2 of the electronic sticky note with sticky note number 4 is 0.035, which is smaller than the minimum readable character size of 0.05 for participant 2. On the other hand, in the example of Figure 16, the display character size 2 of "Summary" is 1 x 24 (dots) / 400 (dpi) = 0.07 (inches), which is larger than the minimum readable character size of 0.05 for participant 2. Therefore, "Summary" is set as display content 2.

[0087] Other than these, there is no problem if the display content is set to "text", so the display content is set to "text" as shown in FIG.

[0088] At this time, the display of the UI screen 1700 of participant 1 is, for example, as shown in Figure 17. The display of the UI screen 1800 of participant 2 is, for example, as shown in Figure 18. Comparing these, the UI screen 1800 display of participant 2 displays six electronic sticky notes 408a to 408f corresponding to sticky note numbers 1 to 6, but the UI screen 1700 of participant 1 displays only three electronic sticky notes 408a to 408c corresponding to sticky note numbers 1 to 3.

[0089] In this case, in order for participant 1 to see all of the electronic sticky notes 408a to 408f, it is necessary to reduce the screen display of the display area 1701 of the UI screen 1700. For example, if participant 1 changes the magnification rate of the display area 1701 to 1 / 2, the UI screen 1700 will be displayed as shown in Fig. 19. In the second embodiment, an example of the process of adjusting the character size at this time will be described.

[0090] The flowchart of the electronic sticky note display process according to the second embodiment may be the same as the flowchart of the electronic sticky note display process described in the first embodiment, and detailed description of the same processes as those in the first embodiment will be omitted here.

[0091] 3, the operation acceptance unit 13 of the terminal device 10 determines whether the end button 406 has been pressed. If the end button 406 has not been pressed, the operation acceptance unit 13 shifts the process to step S302. On the other hand, if the end button 406 has been pressed, the operation acceptance unit 13 terminates the process of FIG. 3.

[0092] In step S302, the operation accepting unit 13 determines whether the zoom scale has been operated. Here, it is assumed that participant 1 has changed the magnification ratio to 1 / 2 by operating the zoom scale 409. Since the zoom scale 409 has been operated, the operation accepting unit 13 proceeds to step S307.

[0093] When the process proceeds to step S307, the display server 100 executes the process of Fig. 7. In the process of Fig. 7, when i = 1, in step S702, the character size determination unit 103 determines whether the character size of the electronic sticky note is within the visible range of participant 1.

[0094] Originally, in the electronic sticky note data 500 of Fig. 16, the row "Display Character Size 1" indicates the display character size of participant 1, but when participant 1 changes the magnification rate to 80%, all of these values ​​become 80%. This state is shown in Fig. 20.

[0095] In the electronic sticky note data 500 shown in Fig. 20, the values ​​in the row for "display character size 1" of the electronic sticky note data 500 in Fig. 16 are all 80%. In this case, since the minimum readable character size for participant 1 is 0.1, the character sizes of the electronic sticky notes with numbers 1, 2, 5, and 6 are insufficient. Therefore, the character size determination unit 103 determines that the character size of the electronic sticky notes is outside the visible range of participant 1, and proceeds to step S704.

[0096] In step S704, the character size determination unit 103 uses the "summary" or "keywords" to calculate a display character size that will enable participant 1 to read the characters.

[0097] In step S705, the information management unit 105 updates the electronic sticky note data 500 of participant 1. Note that since the change is only for participant 1 here, the electronic sticky note data 500 of participants 2 to 4 is not changed in the processing of FIG.

[0098] 7 ends, in step S308 of FIG. 3, the display content determination unit 104 determines the display content to be displayed on the electronic sticky note by each terminal device 10, based on the display character size determined by the character size determination unit 103. For example, the display content determination unit 104 determines the display content so that the display character size is larger than the minimum readable character size.

[0099] For example, the character size determination unit 103 determines the display character size for displaying "Summary" and the display character size for displaying "Keywords" in step S704 of FIG. 7 . In this case, if the display character size for displaying "Summary" is equal to or larger than the minimum readable character size for the participants, the display content determination unit 104 determines the display content to be "Summary." If the display character size for display content 1 and 5 of sticky note numbers 1 and 5 is set to "Summary," and the display content for sticky note number 2 is set to "Keywords," the set character size is both 28 points, so the display character size is 0.8 × 28 (dots) / 200 (dpi) = 0.112. Furthermore, if the display content 6 of sticky note number 6 is set to "Keywords," the set character size is 32 points, so the display character size is 0.8 × 32 (dots) / 200 (dpi) = 0.128. This exceeds the minimum readable character size. In this way, the example of FIG. 21 is obtained.

[0100] Depending on the reduction rate, even if you set all display content to keywords and try to increase the font size, it may end up being smaller than the minimum readable font size. However, since the reduction rate is adjusted by the participants themselves, it is unlikely that they will make it smaller than their own minimum readable font size. Alternatively, the system may determine the range of zoom so that it is not possible to reduce the font size below the minimum readable font size.

[0101] As another example, the display content determination unit 104 may cooperate with the character size determination unit 103 to determine the display content together with the display character size in step S704 of FIG.

[0102] Through the above processing, the display server 100 can obtain, for example, electronic sticky note data 500 as shown in FIG.

[0103] In step S309, the display control unit 12 of each terminal device 10 displays the display content determined by the display server 100 on the electronic sticky note, and the process returns to step S301. At this time, the UI screen 1700 of participant 1 becomes as shown in FIG. 22, and multiple electronic sticky notes 408a to 408f can be displayed so that the display content can be read.

[0104] Participant 1 can return the magnification rate to 1 to display the UI screen 1700 of participant 1 again, as shown in Fig. 17. The other participants 2 to 4 can also change the magnification rate of the display area of ​​the UI screen.

[0105] As described above, according to the second embodiment, each participant can individually change the magnification ratio of the display area of ​​the UI screen. Furthermore, even when the magnification ratio is changed, the electronic sticky note display system 1 can display the display content of the electronic sticky note displayed by each of the multiple terminal devices 10 as small as possible, but at least at a readable character size.

[0106] Third Embodiment In a third embodiment, an example will be described in which participants can set their preferred character size for electronic sticky notes.

[0107] In Examples 1 and 2, the minimum readable character size for each participant was determined as a readable character size 900 as shown in Fig. 7. For example, the character size determination unit 103 determined the display character size so that it exceeded the minimum readable character size. Also, in Examples 1 and 2, the display content determination unit 104 determined the display content so that the display character size was larger than the minimum readable character size.

[0108] In Example 3, participants pre-set their preferred character size instead of the minimum readable character size. The character size determination unit 103 determines the display character size so that the difference between the preferred character size and the display character size is minimized. The display content determination unit 104 determines the display content from "text," "summary," or "keywords" so that the difference between the preferred character size and the display character size is minimized.

[0109] As a result, according to the third embodiment, the participants can set the display character size of the electronic sticky note.

[0110] <Hardware Configuration> The display server 100 and the terminal device 10 according to this embodiment have, for example, the hardware configuration of a computer 2300 as shown in Fig. 23. Alternatively, the display server 100 is realized by a plurality of computers 2300. Note that the computers are not limited to physical machines and may be, for example, virtual machines on the cloud.

[0111] Fig. 24 is a diagram showing an example of the hardware configuration of a computer. In the example of Fig. 23, a computer 2300 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 2300 may further include a GPU (Graphics Processing Unit) or the like.

[0112] A program for realizing processing in the computer 2300 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.

[0113] 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.

[0114] The CPU 1004 may be a processor such as a DSP (Digital Signal Processor), a PLD (Programmable Logic Device), or an FPGA.

[0115] Effects of the Embodiment According to the present embodiment, in the electronic sticky note display system 1 in which a plurality of terminal devices share electronic sticky notes, the content of the electronic sticky notes displayed by each of the plurality of terminal devices 10 becomes easier to read.

[0116] For example, according to the electronic sticky note display system 1 according to the present embodiment, the display contents of the electronic sticky notes displayed by each of the multiple terminal devices 10 can be displayed as large as possible, at least in a readable character size.

[0117] Furthermore, the electronic sticky note display system 1 according to this embodiment allows each participant to individually change the magnification ratio of the display area in which multiple electronic sticky notes are displayed. Furthermore, even when a participant changes the magnification ratio of the display area, the electronic sticky note display system 1 can display the contents of the electronic sticky notes displayed by each of the multiple terminal devices 10 in an easily readable manner.
