Description

[Technical Field]

[0001] This invention relates to a system that allows a sharer to detect the identity of a screen when it is shared. More specifically, this invention relates to a system that notifies a sharer whether the content displayed on the terminals of multiple users is the same. This invention also relates to a system that notifies a sharer of information regarding an answer field that has been entered. [Background technology]

[0002] Even when screen content is shared and displayed between multiple devices, it is difficult to know which part of the screen content a particular sharer is displaying on the screen, which makes it difficult to share information appropriately between sharers.

[0003] Japanese Patent Application Laid-Open Publication No. 2016-053773 describes a system for efficiently displaying elements to be shared. Systems that determine whether an element is set for shared display and efficiently display elements to be shared are publicly known. However, no system is known that allows a sharer to detect the identity of the screen display when the screen is shared, and no system is known that notifies a sharer of information regarding the answer field that has been entered.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2016-053773 Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention aims to provide a system for informing users whether the content displayed on the terminals of multiple users is the same, for example, and a system for informing users of information regarding the answer fields that have been entered. [Means for solving the problem]

[0006] We provide a system that notifies users whether the content displayed on the terminals of multiple users is the same, and also provides a system that, when an answer field on a questionnaire is entered on one terminal, displays information about the question item corresponding to the answer field on another terminal. This invention is based on the knowledge that presentations, etc. can be made efficiently by informing the sharer whether the content displayed on the terminals of multiple users is the same, and by informing the sharer of information regarding the answer fields that have been entered.

[0007] This system is configured by connecting a first terminal and a second terminal in the following manner. An object displayed on a first terminal is referred to as a first object. An object displayed on a second terminal is referred to as a second object. An indication that the first object and the second object are the same is referred to as an "identical indication." An indication that the first object and the second object are different is referred to as a "differential indication." The same display and the different display are displayed on either or both the screen of the first terminal and the screen of the second terminal. will be done.

[0008] In a preferred embodiment of this system, the object displayed on the screen of the first terminal is a presentation document, a questionnaire, a photograph, an image, a video, or text.

[0009] In a preferred embodiment of this system, both the same display and the different display are displayed on either or both of the screens of the first terminal and the second terminal, and the same display and the different display differ in one or more of the following: color, icon, graphic, and display character.

[0010] In a preferred embodiment of this system, when an object is displayed on the screen of a second terminal in response to a sharing instruction from a first terminal, information is displayed on the first terminal as follows: In the above case, the first terminal displays identification information about the second terminal and either or both of an identical display and a different display.

[0011] A preferred embodiment of this system is as follows. The system 1 is connected to one or more terminals other than the first terminal and the second terminal. When the same display is displayed on the first terminal, the number of terminals other than the first terminal on which an object identical to the first object is displayed on the display unit, or the percentage of terminals other than the first terminal on which an object identical to the first object is displayed on the display unit, is displayed. When the difference display is displayed on the first terminal, the number of terminals on which an object identical to the first object is not displayed on the display unit, or the percentage of terminals on which an object identical to the first object is not displayed on the display unit, is displayed.

[0012] A preferred embodiment of this system is as follows: The first object is a questionnaire containing a plurality of question items and a plurality of answer fields corresponding to the plurality of question items. When an answer field of the questionnaire is entered on the second terminal, information about the question item corresponding to the answer field is displayed on the first terminal. [Effects of the Invention]

[0013] We provide a system that notifies users whether the content displayed on the terminals of multiple users is the same, and also provides a system that, when an answer field on a questionnaire is entered on one terminal, displays information about the question item corresponding to the answer field on another terminal.

DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. The system 1 of the present invention is not limited to the embodiments described below, but also includes appropriate modifications of the embodiments below within the scope obvious to those skilled in the art.

[0016] <Outline of the information processing system> First, an overview of the system 1 of the present invention will be described. Fig. 1 is a conceptual diagram for explaining the configuration of the system 1 of the present invention. As shown in Figure 1, a first terminal 3 and a second terminal 5 are connected to the system 1 of the present invention. In addition to these, a plurality of terminals (such as a third terminal 6) having functions equivalent to those of the above terminals may also be connected to the system 1. Furthermore, the above terminals are connected so as to be able to exchange information with each other via information and communication lines such as the Internet. Specific examples of the above terminals are information processing terminals such as computers, tablet terminals, and smartphones. An analysis server or the like may be connected to the system 1 to compare the display information on the screens of the terminals described below. However, if the above-mentioned display information comparison process is performed on each terminal, the connection of an analysis server is not essential.

[0017] The system 1 also has a display information comparison unit (14a or 14b) and an input answer field identification unit 15a. The display information comparison unit (14a or 14b) is an element for comparing the display contents of the object displayed on each terminal. The entered answer column identification unit 15a is an element that notifies the first terminal of information regarding the question items corresponding to the answer columns of the questionnaire entered at the second terminal 5, and displays that information on the first terminal. The system 1 is for confirming whether the object displayed on the screen of each terminal is the same. Furthermore, when information is entered into the answer field of the questionnaire 24 on the second terminal 5, the system 1 is for displaying information on the question item corresponding to the answer field on the first terminal 3. For example, in the system 1 of the present invention, if the terminals that confirm the identity of the above-mentioned object are the first terminal 3 and the second terminal 5, the terminals may transmit display information regarding the object displayed on each terminal to each other. Then, based on the display information, a comparison process of the display information is performed, and display control of the same display 11 and the different display 13 is performed. Furthermore, when verifying the identity of the object in the system 1 among three or more terminals, it is preferable to designate one of the terminals as the presenter terminal. For example, the first terminal 3 may be set as the presenter terminal. In this case, display information regarding the object displayed on multiple terminals other than the first terminal 3 is transmitted to the first terminal 3 via the communication unit. Then, the display information comparison unit 14a of the first terminal 3 (presenter terminal) performs a comparison process based on the display information regarding the above-mentioned object to determine whether the object displayed on multiple terminals other than the first terminal 3 is the same as the object displayed on the first terminal 3.

[0018] The questionnaire 24 also has question items 26 representing questions to the user and answer fields 28 for inputting answers to the questions. There may be one or more question items 26 per questionnaire 24. Similarly, there may be one or more answer fields 28 per questionnaire 24. The questionnaire 24 is displayed on the screen of each terminal by operation of the user of each terminal. Each question item 26 corresponds to one of the answer fields 28. The question items 26 may be, for example, sentences expressing questions about the user's attributes or profile, or may be written in words. The answer fields 28 are input fields where the user inputs answers to the question items 26. The answer fields 28 may be list boxes, text boxes, check boxes, etc. The questionnaire 24 may be displayed by executing an application program stored in a storage unit, or may be saved and read as a document file.

[0019] (Configuration of the first terminal 3, second terminal 5 and each terminal) The first terminal 3, the second terminal 5, the third terminal 6 and the configuration of each terminal will be described. As shown in Figure 2, the first terminal 3, the second terminal 5, and the terminals connected to the system 1 each have a display unit (16a, 16b, or 16c), a communication unit (18a, 18b, or 18c), a control unit (20a, 20b, or 20c), an operation unit (22a, 22b, or 22c), and a memory unit (23a, 23b, or 23c). Furthermore, the first terminal 3, the second terminal 5, the third terminal 6, and each terminal have a display information comparison unit (14a, 14b, or 14c, etc.). Furthermore, the first terminal 3 has an input answer column identification unit 15a. Each element is connected by a bus or the like, allowing information to be exchanged. Furthermore, the computer of each terminal may have an arithmetic unit. For example, the memory unit may store a control program or various types of information. When predetermined information is input from the operation unit, the control unit reads out the control program stored in the memory unit. The control unit then reads out the information stored in the memory unit as appropriate and transmits it to the arithmetic unit. The control unit also transmits the input information as appropriate to the arithmetic unit. The arithmetic unit performs arithmetic processing using the various types of information it receives and stores the results in the memory unit. The control unit reads out the arithmetic results stored in the memory unit and displays them on the display unit. In this way, various types of processing are executed. Each element described below may correspond to any element of a computer.

[0020] (Display information comparison section) The display information comparison unit is an element for determining whether the object displayed on the display unit of the first terminal 3 is the same as the object displayed on the display unit of another terminal. For example, the above determination is made by the following process. First, the case where this processing is executed between the first terminal 3 and the second terminal 5 will be described. FIG. 3 is a diagram showing the flow of processing performed between two terminals in the system of the present invention. Presentation materials, questionnaires, photographs, images, videos or texts are displayed on the display unit 16a of the first terminal 3 in response to inputs made by the user to the operation unit. For example, if the first object displayed on the display unit 16a of the first terminal 3 is a questionnaire, the first object may be as shown in FIG. Information about the displayed content at a predetermined time is transmitted to the second terminal 5 via the communication unit. Similarly, presentation materials, questionnaires, photographs, images, videos, or text are displayed on the display unit 16b of the second terminal 5 in response to a user's input to the operation unit. At this time, it is preferable that a sharing instruction from the first terminal 3 is transmitted to the second terminal via the communication unit, and the content is displayed on the display unit 16b of the second terminal 5 via the control unit 20b. Here, a sharing instruction means that when content displayed on a certain terminal is to be displayed on another terminal, permission to display the content is given to the other terminal. Then, display information about the object displayed on the second terminal 5 at a predetermined time is transmitted to the first terminal 3 via the communication unit.

[0021] Next, the display information comparison unit 14a of the first terminal 3 performs a comparison process between the display information of the second object transmitted from the second terminal 5 via the communication unit and the display information of the first object displayed on the display unit 16a of the first terminal 3. For example, a portion of the screen of the above terminal to be compared in the comparison process (a display image comparison portion) may be set in advance, and the image information of the display image comparison portion relating to the object of the first terminal 3 and the display image comparison portion relating to the object of the second terminal may be compared in the display information comparison process. A known image information analysis means may be used in this image information comparison. Similarly, the display information comparison unit 14b of the second terminal 5 performs a comparison process between the display information of the first object transmitted from the first terminal 3 and the display information of the second object displayed on the display unit 16b of the second terminal 3.

[0022] In the above-mentioned image information comparison process, if the information of the display image comparison portions overlaps at a predetermined rate or more, it may be determined that the first object and the second object are the same. On the other hand, if the above is not the case, the first object and the second object may be determined to be different. Then, information linking the terminal identification number with the above comparison result is created. A publicly known image analysis technique may be used to measure the above overlap range.

[0023] The predetermined ratio in the comparison of the display image comparison portion may be 50% or more and 100% or less, 60% or more and 90% or less, 70% or more and 85% or less, or any value set by the user of the system 1. Furthermore, the display image comparison portion may be set arbitrarily by each user of the system 1 via the operation unit and stored in the storage unit. In addition, the coordinates of the scroll position on the screen of each terminal may be obtained, compared, and checked to see if they overlap within a predetermined range, and the above-mentioned comparison processing of the display information may be performed. The above is the case where comparison processing of objects displayed on each screen between two terminals is performed. Note that in the above comparison processing, the display information of objects displayed on each terminal may also be compared based on other known methods.

[0024] Furthermore, the display information comparison unit compares the input contents displayed on the first terminal 3 with those displayed on other terminals. A comparison process may be performed to determine whether the displayed input contents are the same or not. A specific example of the above comparison process will be described below. First, for example, a questionnaire 24 is displayed by a user operation on the display unit 16a of the first terminal 3. Then, via an instruction to send, receive, and share the file of the questionnaire 24, the questionnaire 24 is displayed on the display unit of a terminal other than the first terminal 3 (here, the second terminal 5). Next, it is assumed that the user of the second terminal 5 inputs information via the operation unit 22b into an answer field (assumed to be answer field A1) corresponding to a certain question item in the questionnaire 24. Thereafter, it is assumed that the input content is reflected in the answer field (assuming answer field A2) corresponding to the answer field A1 in the questionnaire 24 displayed on the display unit of the first terminal 3. It should be noted that answer field A1 and answer field A2 are answer items corresponding to the same question content (for example, user attributes).

[0025] At this time, the input contents may be reflected by automatic processing via a communication line, or may be input directly by the user of the first terminal 3 via the operation unit 22a. Then, display information of the above-mentioned input contents in the answer column A1 of the questionnaire 24 displayed on the second terminal 5 is transmitted to the first terminal 3. Then, a comparison process is performed by the display information comparison unit 14a between the display information of the input contents in the answer column A2 displayed on the first terminal 3 and the display information of the input contents in the answer column A1 of the second terminal 5. If the information is the same, it may be determined that the display contents of those answer columns are the same. Also, if the information is different, it may be determined that the display contents of those answer columns are different. Furthermore, based on the above-mentioned comparison results, the above-mentioned comparison results for each terminal identification number and question item may be displayed in a list on the display unit of each terminal.

[0026] In addition to the above comparison method, the display information of the object may be compared by comparing the information in the transmission-completed file and the reception-completed file to confirm that the file for displaying the object to be displayed on each terminal has been successfully transmitted and received. Specifically, for example, the first terminal 3 transmits to another terminal (here, the second terminal 5) a file of the object to be displayed on the display unit of that terminal (referred to as the object display file). Next, the first terminal 3 transmits a transmission-completed file to the second terminal 5 to notify that the transmission process of the object display file has been completed. At this time, it is preferable that the first terminal 3 saves a duplicate file of the transmission-completed file.

[0027] Next, the second terminal 5 (or another terminal) transmits the received transmission completion confirmation file to the first terminal 3 as a file (reception completion confirmation file) for notifying that the reception process of the object display file has been completed on the second terminal 5 side. At this time, it is preferable to save a copy of the reception completion confirmation file on the second terminal 5. Note that in the transmission process, the file transmitted to the first terminal 3 may not be the reception completion confirmation file, but may be a copy of the reception completion confirmation file. Then, in the first terminal 3, the information in the above-mentioned transmission completion confirmation file and reception completion confirmation file is compared via the display information comparison unit 14a, and if the information is identical, it may be determined that the first object and the second object are the same. Also, if the information is different, it may be determined that the first object and the second object are different. In this comparison process, the identification information of the files may be compared, or binary data or arbitrary information contained in the files may be compared. Note that the above-mentioned transmission completion confirmation file and reception completion confirmation file may be substituted with the above-mentioned object display file.

[0028] Next, a case where the system 1 is used with three or more terminals will be described. In this case, one of the terminals may function as a presenter terminal (which may be the first terminal 3). In other words, using the first object displayed on the display unit 16a as a reference, it is confirmed whether the reference object and the objects displayed on each of the other terminals are the same.

[0029] Specifically, first, information on the display image of the object displayed on each of the multiple terminals connected to the system 1 is transmitted to the first terminal 3, which is the terminal for the presenter, via the communication unit. At this time, it is preferable that the display image information is linked to identification information related to the terminal from which the information was transmitted. Then, using the same image comparison method as that performed between the two terminals described above, the display information comparison unit 14a performs a process of comparing the first object with the objects displayed on each of the terminals other than the first terminal 3. Then, comparison result information on the objects of each terminal is created. This comparison result information is preferably comparison result information of the object for each identification number related to the terminal. Based on this comparison result information, the same display 11 or difference display 13 described below is performed. Furthermore, based on the above information, the percentage or number of terminals displaying an object identical to the first object may be displayed. Similarly, based on the above information, the percentage or number of terminals not displaying an object identical to the first object may be displayed. Note that when an object displayed on the first terminal 3 is displayed on a terminal other than the first terminal 3, it is preferably performed based on a sharing instruction regarding that object from the first terminal 3 to the other terminals.

[0030] (Same display, different display, number of terminals and percentage display (display of display target results)) FIG. 5 is a diagram showing an example of an identical display 11 and a different display 13 displayed in the system of the present invention. Figure 6 shows the percentage and number of terminals of identical displays displayed in the system of the present invention, and the percentage and number of terminals of different displays. Figure 6(a) is an example of the percentage and number of terminals of identical displays displayed in the system of the present invention. Figure 6(b) is a diagram showing the percentage and number of terminals of different displays displayed in the system of the present invention. Based on the comparison result information obtained by the comparison process of the display information, the same display 11, the different display 13, the number of terminals and the ratio may be displayed. The same display 11 and the different display 13 differ in one or more of the following: color, icon, graphic, and display character. First, we will explain the case where the above comparison process is performed between two terminals (first terminal 3 and second terminal 5) using system 1. The control unit 20a of the first terminal 3 refers to the comparison result information created by the above comparison process, and if the comparison results are identical, it causes the display unit 16a of the first terminal 3 to display an identical display 11. If the comparison results are different, it causes the display unit 16a of the first terminal 3 to display a different display 13. At this time, it is preferable that the above display be for each terminal identification number or user name.

[0031] In this case, the same display 11 or difference display 13 is also displayed on the display unit 16b of the second terminal 5 in the above manner and under the above conditions. Specific examples of the same display 11 and difference display 13 are colors, icons, graphics, or character displays. For example, when the same display 11 and difference display 13 are displayed in color, if a green marker is displayed on the screen, it indicates that the comparison results are the same, and if a yellow marker is displayed, it indicates that the comparison results are different. In addition, a circle may be displayed if the comparison results are the same, and an cross may be displayed if the comparison results are different. Furthermore, the difference display may be displayed only if there is a difference in the comparison results.

[0032] Next, we will explain the case where the processing of system 1 is executed between three or more terminals, including the first terminal 3, the second terminal 5, and terminals other than those mentioned above, and the same display, different display, number of terminals, and percentage display are controlled. In this case, the first terminal 3 may function as the presenter terminal. The control unit 20a of the first terminal 3 refers to the comparison results for each identification number created by the above comparison process, and if the comparison results are identical, displays an identical display 11 on the display unit 16a of the first terminal 3. If the comparison results are different, displays a different display 13 on the display unit 16a of the first terminal 3. Furthermore, the control unit 20a of the first terminal 3 may refer to the comparison results for each identification number and cause the first terminal 3 to display the percentage of terminals displaying something identical to the first object. In addition, the control unit 20a of the first terminal 3 may refer to the comparison results for each of the above identification numbers and display on the display unit of the first terminal 3 the number or percentage of terminals that display something different from the first object.

[0033] (Entered answer column identification section) The entered answer column identification unit 15a is an element for identifying answer columns corresponding to the question items of the questionnaire 24 entered and answered at the second terminal 5. Its function will be explained below. First, in response to a user's input to the operation unit 22a, the questionnaire 24 including a plurality of question items and answer columns corresponding to these question items is displayed on the display unit 16a of the first terminal 3. Then, the questionnaire 24 is also displayed on the display unit 16b of the second terminal 5 via the communication unit and the control unit. In this case, the questionnaire 24 may not be displayed in its entirety on the display unit of each terminal because the display layout of the questionnaire 24 is long vertically or horizontally, or the size of the questionnaire 24 on the screen is large. In such cases, the entire contents of the questionnaire cannot be seen unless the screen is scrolled. This causes the following problems:

[0034] For example, suppose that an input is made in an answer field of the second terminal 5 that corresponds to an answer field that cannot be fully displayed on the display unit 16a of the first terminal 3, among the above answer fields displayed on the second terminal 5. Then, suppose that the input content is sent to the first terminal 3 via the communication unit and reflected on the display unit 16a. At this time, because the above answer field is located in a position that cannot be fully displayed on the display unit 16a of the first terminal 3 without scrolling the screen, etc., the user of the first terminal 3 may not be aware that the input has been made.

[0035] Therefore, in the system 1 of the present invention, the following configuration is adopted so that even in the above case, the user of the first terminal 3 can sense that the above input has been made. Suppose that, while the same questionnaire 24 is displayed on the display units of the first terminal 3 and the second terminal 5, an input is made into one of the answer fields via the operation unit 22b of the second terminal. At that time, identification information for the question items and answer fields is transmitted from the second terminal 5 to the first terminal 3 via the communication unit. It is preferable that the transmitted content includes identification information for the second terminal 5.

[0036] Then, when the first terminal 3 receives the above information via the communication unit, based on that information, the input answer field identification unit 15a creates a message and display content information to notify the user of the first terminal 3 of the input location of the above answer. The input answer field identification unit 15a identifies the corresponding question item based on the identification number of the input answer field, and creates a message and display content related to the question item for the terminal 1. The message and display content preferably indicate the name of the user who made the input in the answer field (or the identification information of the terminal) and the question item for which the input was made. This message or display content may be something like "Mr. A has entered information into the household field" when the answer field for the "household field" is entered by a user (assumed to be Mr. A) of the second terminal 3. Then, the message or display content is displayed on the display unit 16a via the control unit 20a of the first terminal 3. FIG. 7 is a diagram illustrating an example in which the user of the second terminal 3 inputs information into the response field of the "household field." In addition, when the user of the second terminal 3 inputs via the operation unit that he / she agrees with the information entered in the answer field, the user's name and a message indicating that he / she agrees may be displayed on the display unit of the first terminal.

[0037] (Display unit, communication unit, control unit and operation unit) The first terminal 3, the second terminal 5 and the terminals connected to the system 1 may basically have a display unit, a communication unit and a control unit.

[0038] The display unit (16a, 16b, or 16c) is an element for displaying visual information such as images, videos, etc. The display unit (16a, 16b, or 16c) may be, for example, any of various display devices.

[0039] The communication unit (18a, 18b or 18c) is composed of a communication interface and has the function of transmitting and receiving information between each terminal connected to the system 1. Through this element, each terminal transmits various information, such as display information of an object displayed on the display unit of each terminal, to other terminals, and receives various information, such as display information of an object displayed on the display unit of other terminals.

[0040] The control unit (20a, 20b or 20c) is a means for controlling each unit, such as transmitting and receiving information, storing information in the memory unit, and controlling the content displayed on the display unit.

[0041] The operation unit (22a, 22b, or 22c) is an element for receiving input of operation information from the user of each of the above terminals. The operation information input via the operation unit is transmitted to the control unit and used to control each terminal. The operation unit can employ various keyboards, mice, and touch panels that are used in known information processing terminals. The touch panel that constitutes the operation unit may also constitute a touch panel display together with the display that constitutes the display unit.

[0042] <1. Information processing operation of System 1 (when three or more devices are connected to System 1)> Next, the processing of the information processing system according to an example of an embodiment of the present invention will be described. Fig. 8 is a diagram showing a processing flow when processing is performed among three terminals in the system of the present invention. It should be noted that the processing flow described below is an example of internal processing for realizing the system 1 of the present invention, and the internal processing that can be used in the system 1 of the present invention is not limited to the example below.

[0043] (1-1. Sending and receiving display information of objects displayed on the terminal) The following example describes a case where three or more terminals are connected to the system 1 and the user of the first terminal 3 is a presenter who presents materials on the system 1. When a user of the first terminal 3 (presenter terminal) operates the operation unit 22a, a first object is displayed on the display unit 16a of the first terminal 3. Then, a sharing instruction regarding the first object is transmitted via the communication unit to terminals other than the first terminal 3 connected to the system 1, and an image of the first object is displayed on the display units of those terminals (display of object: S01).

[0044] (1-2. Comparison of display information of objects displayed on the device and acquisition of comparison results) In the display information comparison unit 14a of the first terminal 3, a comparison process between the display information of the second object received from the second terminal 5 and the display information of the first object displayed on the first terminal 3 is performed in the manner described above (display information comparison process: S02). Similarly, in the display information comparison unit 14a of the first terminal 3, a comparison process is performed in the above-mentioned manner between the display information of the third object received from the third terminal 6 and the display information of the first object displayed on the first terminal 3 (display information comparison process: S02). Based on this display information comparison process, the first terminal 3 can obtain display information comparison result information as to whether the first object and the object displayed on the other terminal are the same or not. If the comparison results are different, a retransmission instruction may be transmitted from the first terminal 3 to another terminal (such as the second terminal 5 or the third terminal 6) via the control unit and the communication unit to prompt the other terminal (such as the second terminal 5 or the third terminal 6) to retransmit the display information (retransmission of information from a terminal other than the first terminal 3 to the first terminal 3). This retransmission instruction may be message information or the like displayed on the screen. If the comparison results are different, in this processing example, this retransmission instruction may be transmitted from the first terminal 3 to the second terminal 5 or the third terminal 6 or the like (terminals whose comparison results of the display information differ from those of the first terminal). This prompts the latest information displayed on the first terminal 3 to be displayed on each of the other terminals.

[0045] It should be noted that this comparison process may not be performed on the first terminal, but may be executed on an analysis server connected to the system 1, and only the comparison results may be transmitted from the analysis server to the first terminal 3, etc.

[0046] (1-3. Display of comparison results) Next, in the first terminal 3, display control of the same display 11 and the different display 13 is performed based on the comparison result of the above-mentioned display information. As described above, depending on whether the comparison result of the display information is same or not, display control of the same display 11 and the different display 13, their ratio, and the number of terminals may be performed for each identification number of each terminal (display of display target comparison result: S03).

[0047] <2. Information processing behavior in System 1 (when a questionnaire is displayed)> In the following example, a case will be described in which processing of the system 1 is executed between two terminals and a questionnaire 24 is displayed on the display units of the first terminal 3 and the second terminal 5. Fig. 9 is a diagram showing the processing flow when processing is executed between two terminals in the system of the present invention and the object to be displayed is the questionnaire 24. (2-1. Notification of input fields) First, after the user inputs information into the operation unit and the above-mentioned process of comparing the sharing instruction and the display information, the same questionnaire 24 is displayed on the display units of the first terminal 3 and the second terminal. Next, when an input is made in any of the answer fields of the questionnaire 24 on the second terminal 5 (information input in the answer field of the questionnaire: S04), the identification information of the answer field and the identification information of the terminal where the input was made are transmitted to the first terminal 3. Then, the input location identification unit 15a of the first terminal creates a message and display content to notify the user of the first terminal 3 of the input location of the answer using the method described above (input location notification message creation: S05). Then, the message notifying the input location is displayed on the first terminal 3 (input location notification: S06).

[0048] In the above, in order to realize the contents of the present invention, the present specification has described embodiments of the present invention with reference to the drawings. However, the present invention is not limited to the above embodiments, and includes modifications and improvements that are obvious to those skilled in the art based on the matters described in the present specification.

[0049] This specification provides a program for causing a computer to function as the above-mentioned system, and an information recording medium storing the program. This program is implemented in a computer and causes the computer to function as a system having means for performing a comparison process of displayed information to confirm whether an object displayed on a first terminal is the same as an object displayed on another terminal, and means for creating an input location notification message to notify the user of information regarding the answer field entered on the questionnaire.
