In the figure, 2 is an input means for receiving a command input from the operator 1, 3 is an input analysis means for analyzing the input, 4 is a message communication means for transmitting a message to another terminal based on the result of analyzing the input, 5 Is application processing means for executing application processing based on a message from another terminal. Further, 6 is a plurality of terminal devices composed of the respective constituent elements 2 to 5, 7 is a broadcast communication control means for communicating between the terminals,
Reference numeral 8 is a network for connecting each terminal device.

Next, the operation will be described. The input analysis unit 3 analyzes a command from the operator 1 input via the input unit 2, determines a process corresponding to the command defined in the application program in advance, and outputs a message corresponding to the process. Input to the message communication means 4. The message communication means 4 includes information for specifying an operation target on which the process is performed,
Information necessary for a plurality of application programs to share execution results is added or included in the message and sent to all terminal devices through the broadcast communication control means 7. On the other hand, in the terminal device 6 which has received the message via the broadcast communication control means 7, the application processing means 5 executes the application program processing corresponding to the message.

Although the message is sent to all terminals through the broadcast communication control means here, in the terminal 3 where the command is input,
The message is sent to the broadcast communication control means 7 and the processing of the corresponding application is executed, and the broadcast communication control means 7 broadcasts the message to all terminals other than the terminal device that issued the message. It may be configured as follows. In this way, all the terminal devices connected to the network perform common processing on the command input to one terminal device, and the same execution result is obtained.

[0005]

Since the conventional application sharing system is configured as described above, the message determined by the command input from the command input means corresponds to the processing of the application. , Does not indicate to which operation target the process is executed. Therefore, when there are multiple operation targets on which the same process is executed, various types of information necessary for the process to specify which operation target the process is executed are added or included in the message and sent. However, if such information is included, the amount of data transfer increases, and if the number of terminals sharing the application is large or the network load is high, the application cannot be shared in real time. was there.

In addition, in the terminal device that receives the message, each time the message is transferred, various kinds of information added or included in the message are analyzed to specify an operation target on which the process is to be performed. There is a problem that the application cannot be shared in real time due to the delay required for the processing.

The present invention has been made to solve the above problems, and holds an identifier corresponding to a process defined in an application and an identifier corresponding to an operation target generated in the application in advance.

In FIG. 1, a teacher and a student each have a terminal device 6
It is assumed that the user sits down, starts an online text using hypertext as the application processing means 5 to be shared, and starts the lesson. When the online text is activated in each terminal device, first, the application processing means 5 and the processing / target identifier holding means 9 shown in FIG. 1 execute the processing shown in FIG. In FIG. 2, when the online text is activated, the application processing means 5 reads the description of the teaching material contents (step S101), and generates and arranges the object to be displayed on each page of the teaching material based on the content description of the teaching material (step S101). S10
2). Next, the application processing means 5 sends the generated target and the processing defined for the target to the processing / target identifier holding means 9 (step S103). The processing / target identifier holding means 9 generates an identifier for identifying the processing / target based on the sent target and the processing defined for the target, and registers / holds the target in correspondence with the processing content. Is performed (step S104). By repeating steps (S103) to (S104) until all the processes defined for the target are completed (step S105), the identifiers of all the processes corresponding to the generated target are registered. finish. Also, from step (S102) to step (S10)
By repeating the steps up to 5) until the content description of the teaching material is completed (step S106), identifiers for all operation targets and processing contents displayed on the online text are registered as shown in the table of FIG. .

FIG. 7 is a generation example of the result of performing the processing described in FIG. 2 on the screen display of the online text shown in FIG. 5, and represents the processing identifier for each operation target in a table format. . For example, with respect to the hidden text 14 in FIG. 5, there is a process of displaying a sentence and a process of hiding the sentence as corresponding processes, and since the hidden text 14 is the fourth operation target generated by the application, “ It is registered as two processing / target identifiers of "display: 4" and "hiding: 4".

When the teacher operates the operation target on the online text in his / her own terminal device during class,
The process is executed according to the procedure shown in FIG. This state is shown in FIG.
The operation of displaying the sentence on the screen by the teacher clicking the hidden text 14 in the above with the mouse will be described. The mouse click operation performed on the hidden text 14 by the teacher is performed through the input means 2 and the input analysis means 3
(Step S111). Based on the received input, the input analysis unit 3 identifies the hidden text 14 which is the operation target on which the operation is performed, and determines the display process which is the application process performed on the target (step S112). . The specified operation target "hidden text 14" and the display process are sent to the process / target identifier holding means 9, and the application processing means 5 executes the display process of the hidden text 14 for the target (step S113). Then process
The target identifier holding unit 9 identifies the received operation target “hidden text 14” and the process / target identifier “display: 4” corresponding to the display process of the application, and processes / targets the other terminal 6 through the information communication unit 10. The identifier is sent (step S114).

On the other hand, the student terminal device 6 which has received the process / target identifier from the information communication means 10 on the teacher terminal device 6 via the network performs the process shown in FIG. First, the information communication means 10 receives the processing / target identifier sent through the network (step S
121) and the information communication means 10 sends the processing / target identifier to the processing / target identifier holding means 9 (step S).
122). The processing / target identifier holding means 9 compares the received processing / target identifier “display: 4” with the information held by itself, and the hidden text 1 as the corresponding operation target.
4 and the display process as the process of the application are specified, and the specified operation target and the process of the application are sent to the application processing unit 5 (step S12).
3). The application processing means 5 executes the display process for the hidden text 14 which is the operation target based on the received operation target and the application process (step S124), which is the same as the operation executed on the teacher side terminal device. Get the execution result.

Next, the configuration of the operation target and the process / target identifier representing the process of the application performed on the operation target will be described with reference to the drawings. FIG. 5 shows a screen example of online text using hypertext operating on each terminal device. In the figure, 1
Reference numeral 1 is a button for moving to the previous page, 12 is a button for moving to the next page, and 13 and 14 are hidden texts, which are used to sequentially display sentences according to the progress of the lesson. The area indicated by a half-tipped mosquito is an object whose sentence is displayed by mouse clicking in the initial state. Reference numeral 13 represents a state in which the sentence is displayed by clicking the mouse, and 14 represents a state in which the sentence is hidden. Further, reference numerals 40 and 41 are hidden images for performing a secondary explanation, and are objects for which an explanatory diagram or a picture is displayed by mouse clicking while the teacher is explaining. 40
Represents a state in which the image is displayed by clicking the mouse, and 41 represents a state in which the image is hidden.

FIG. 6 shows the processing / target identifier expressed as a character string. In the figure, 15 is identifier information corresponding to the processing of the application, 16 is a delimiter character that separates the identifier information, and 17 is an operation target generation. The identification numbers are given in order, and the character string 18 connecting these is the processing / target identifier. Assuming that the button 11 for moving to the previous page, the button 12 for moving to the next page, the hidden texts 13 and 14, and the hidden images 40 and 41 in FIG. 5 are generated in this order when the online text is activated, these operations are performed. As shown in FIG. 7, the target is sequentially set to 1
The identification numbers from 6 to 6 are given. Since all the terminal devices perform processing according to the same online text content using the same application, the same identification number is given to the same operation target in each terminal device.

Button 1 for moving to the previous page in FIG.
In No. 1, as a corresponding process, a button is pressed by a mouse click, and by performing this process, the previous page of the online text is displayed. Therefore, as shown in FIG. 6, the character string “press” that identifies the process corresponding to the button press and “1” that represents the target identification number are connected by the delimiter “:” As determined as the process / target identifier 18, as shown in FIG. 7, the <press process> as the application process and the <previous page button> as the operation target correspond to each other and are registered in the process / target identifier holding means 9. Retained.

Similarly, with respect to the button 12 for moving to the next page in FIG. 5, as shown in FIG. 7, a processing / target identifier 31 of “press: 2” is registered / registered as button pressing processing.
A process of “display: 3” that is held and corresponds to the process for displaying a sentence for the first hidden text 13.
The target identifier 32 corresponds to “hiding:”
The process / target identifier 33 "3" is registered and held.
For the second hidden text 14, a process of “display: 4” corresponding to a process for displaying a sentence, a target identifier 34, and a process of “hiding: 4” for a sentence concealment: The target identifier 35 is registered and held. In addition, for the first hidden image 40, a processing / target identifier 42 of “display: 5” corresponding to the display processing, and a processing / target identifier 43 of “hiding: 5” corresponding to the concealment. Registration /
With respect to the second hidden image 41 which is held, the process “display: 6” corresponding to the process for display, the target identifier 44 corresponds to the process “display: 6” for the concealment,
The target identifier 45 is registered and held. With this configuration, by communicating the character string as the process / target identifier between the terminal devices, it is possible to easily specify the operation target and the process for the target in each terminal, and share the operation in real time. It can be realized by processing.

Next, another configuration example of the processing / target identifier will be described with reference to FIGS. 8 to 10. FIG. 8 shows another configuration example of the process / target identifier, and FIG. 9 is a process when the process / target identifier shown in FIG. 8 is used for the content description of the online text as shown in FIG. The information held by the target identifier holding means is represented in a table format. In FIG. 8, the process / target identifier is represented as a character string, 15 is identifier information corresponding to the process of the application, 16 is a delimiter character that separates the identifier information,
Reference numeral 19 represents identifier information corresponding to the type of operation target, 20 represents an identification number assigned in order of generation for each type of operation target,
The character string 18 that connects them becomes the processing / target identifier.

Button 1 for moving to the previous page in FIG.
In No. 1, there is a corresponding process in which a button is pressed by a mouse click. By performing this process, the previous page of online text is displayed. Therefore, as shown in FIG. 8, the character string “press” for identifying the process corresponding to the pressing of the button, the character string “button” indicating that the target type is the button, and “1” indicating the target identification number. "Press: Button: 1" in which "" is connected by a delimiter ":" is determined as the process / target identifier 18, and as shown in FIG. 9, the <press process> as the application process and the <previous process as the operation target. Page button> is correspondingly registered / held by the processing / target identifier holding means 9.

Here, for the button 12 for moving to the next page in FIG. 5, as shown in FIG. 9, the process / target identifier 31 of “press: button: 2” is used as the button pressing process.
Is registered / held, and the processing / target identifier 32 of “display: hidden text: 1” corresponds to the processing for displaying the text for the first hidden text 13 and also corresponds to the hiding of the text. As a result, the process / target identifier 33 “conceal: hidden text: 1” is registered and held. For the second hidden text 14, a processing / target identifier 34 of “display: hidden text: 2” corresponding to the text display processing.
However, in response to the concealment of sentences, "Concealment: Hidden text:
The process / target identifier 35 "2" is registered and held.
Further, for the first hidden image 40, the processing / target identifier 42 of “display: hidden image: 1” corresponds to the processing for displaying, and “hiding: hidden image:” for the hiding. The process of "1" -The target identifier 43 is registered-
Will be retained. For the second hidden image 41, "display: hidden image: 2" corresponding to the processing for displaying.
The process / target identifier 44 that corresponds to the hiding is registered / held as the process / target identifier 45 “hiding: hidden image: 2”.

Further, when the same processing is performed for all operation objects of the same type as in the case of hiding the first hidden text 13 and the second hidden text 14 in FIG. 10 shows the identification numbers assigned in the order of generation of operation targets of the same type of the process / target identifier shown in FIG.
By setting the special character “*” that matches all the numbers as shown in FIG. 1, the hidden image 4 having the same display process is displayed in the terminal device that receives the process / target identifier.
It is possible to execute the display process that is the application process for all the operation targets 13 and 14 of the hidden text that is the operation target type without performing the display process for 0 and 41.

By adding the identification information indicating the type of the operation target to the process / target identifier, even if the same process is performed on all the operation targets of a specific type, the same process identifier is different. It becomes possible to recognize that the process / target identifier does not correspond to the operation target, and the operation for all the operation targets of the same type can be realized by sending only one process / identifier.

In the present embodiment, the information communication means 10 of each terminal device 6 is configured to communicate necessary information to other terminals, but separately from this, broadcast communication between each terminal device is executed. It is also possible to separately provide a broadcast communication means for performing communication of information from each terminal with the broadcast communication means, and the broadcast communication means executes communication between the terminal devices.

Further, although ":" is used as a character indicating a delimiter between process / target identifiers and "*" is a special character indicating all targets of the same target type, these characters are other characters that can be recognized in the system. May be used.

Further, the processing / target identifier is defined as a character string in which the processing identification information and the target identification information are combined, but the respective identification information is not collected as one character string but is communicated as separate identification information. Maybe again
In this case, each piece of identification information may be information other than a character string.

The correspondence between the process / target identifier and the application process / operation target is stored in a table format. However, if the correspondence between the process / target identifier and the application process / operation target can be stored, another format is used. You may keep it.

Further, the identification information of the target in the processing / target identifier is the identification number assigned in the generation order of the target or the identification number assigned in the generation order of the target of the same type as the identification information indicating the type of the target. Any information can be used as long as it can uniquely identify the operation target, and the identification number may be an identification number or the like assigned in the order of generation within the same page.

The application processing unit 5 performs a process of generating an annotation as a newly created operation target, and a process / target identifier holding unit 9
In addition, the information indicating that the operation target to be generated is a line segment, the coordinate information of the start point and the end point of the line segment, and the like are stored in the operation target generation information determining unit 22 as the information necessary for generating the target. It is sent (step S133). The operation target generation information determining unit 22 collects the information necessary for generating the target as the operation target generation information to be sent to the other terminal device 6, and sends it to the other terminal device through the information communication unit 10 (step S134). .

Next, the processing on the student terminal device 6 which has received the information regarding the generation of the dynamically generated object will be described with reference to FIG. The operation target generation information determining unit receives the operation target generation information necessary for generating a new operation target through the information communication unit 10 (step S14).
1). The received operation target generation information is analyzed, and start point / end point information and the like necessary for generating a line segment as an annotation is sent to the application processing unit 5, and the application processing unit 5 causes the line segment that is the operation target. By generating (step S142), the same annotation as the teacher terminal device can be displayed on the screen. Next, the information necessary for registering the newly generated process / target identifier of the operation target is sent to the process / target identifier holding unit 9 (step S143), and the line that is the operation target in the process / target identifier holding unit 9 is sent. The process / target identifier corresponding to the minute is determined and registered, and the operation target for the subsequent operation is prepared (step S144).

FIG. 19 shows, in a table format, the information held by the process / target identifier holding means 9 when the process / target identifier shown in FIG. 18 is used for the content description of the online text as shown in FIG. Is.

As a process corresponding to the line segments 23 and 25 generated by the teacher or the student in FIG. 17, there is deletion from the screen. By executing this process, the teacher finishes the explanation and the question from the student. When the teacher finishes answering to, the generated annotation can be deleted. Therefore, the line segment 23 generated as an annotation by the teacher is the character string "delete" that identifies the process corresponding to the deletion as shown in FIG.
Then, "5" representing the identification number of the target and "delete: 5: teacher" in which the character string "teacher" representing the operator who generated the target is connected by the delimiter character ":" is determined as the processing / target identifier 36. As shown in FIG. 19, the <delete process> as the application process and the <segment 1> as the operation target are registered / held by the process / target identifier holding mechanism.

Similarly, for the line segment 25 generated by one of the students in FIG. 17, as shown in FIG. 19, the process / target identifier 37 of “delete: 6: student 1” is used as the deletion process.
Registered and held as.

When the same process is performed on all the dynamic operation targets generated by a specific operator, the identification number 17 representing the operation target of the process / target identifier shown in FIG. 18 is set to all the operation targets. By sending the processing / target identifier as a matching “*”, it can be realized without sending the processing / target identifier for each operation target.

By adopting such a configuration, even when the student adds an annotation on the online text for a question while the teacher is explaining, the annotation added by the teacher is not erased. , It is possible to delete the annotation added by the student who asked the question.

Next, regarding another operation example shown in FIG.

FIG. 20 is a diagram showing a flow of processing in the case where a teacher dynamically adds an operation target such as an annotation added to an online text during a lesson, and FIG. 21 is dynamically generated in a student terminal device. FIG. 10 is a diagram showing a flow of processing when receiving information about generation of an operation target.

In the configuration of FIG. 11, for example, if a teacher adds an annotation on the online text screen during class,
The process shown in FIG. 20 is executed on the teacher terminal device. The teacher performs an annotation adding operation on the online text which is an application through the input means 2 (step S151). The input analysis unit 2 analyzes the operation performed by the teacher and generates an annotation as a new operation target using the application unit 5 (step S152). The application processing means 5 requests the processing / target identifier holding means 9 to register the newly created annotation as an operation target (step S153), and the processing / target identifier holding means 9 processes according to the request from the application processing means 5. Application processing means 5 for determining, registering, and holding the target identifier, and for sending the determined process / target identifier together with the operation target generation information to another terminal.

Next, the application processing means 5 sends the information necessary for generating the operation target and the process / target identifier to the operation target generation information determining means 22 (step S155). The operation target generation information determining unit 22 collects the information necessary for generating the target and the process / target identifier as information to be sent to another terminal device 6, and sends the information to the terminal device 6 through the information communication unit 10 (step S156). .

On the other hand, on the other student terminal devices 6 that have received the information regarding the generation of the dynamically generated target, FIG.
Is performed. That is, the operation target generation information determining unit 22 receives the information necessary for generating a new operation target and the information about the process / target identifier through the information communication unit 10 (step S161). The received information is sent to the application processing means 5, and the application processing means 5 generates the operation target (step S16).
2). Next, the application processing unit 5 creates a new operation target and a process / operation target in the process / target identifier holding unit 9.
The target identifier is sent (step S163), the process / target identifier holding unit 9 registers the process / target identifier of the operation target, and prepares for the subsequent operation on the operation target (step S164).

After that, when the dynamically generated operation target is operated, sharing of the application for the operation and its execution result is realized by the same method as described in the first embodiment. To be done.

By sending the process / target identifier generated by the operation-side terminal device together with the operation-target generation information in this way, although the information transfer amount may increase slightly when the operation-target generation information is sent, the receiving-side terminal In the device, it is not necessary to newly determine the process / target identifier based on the information when the operation target is generated. Further, even on a terminal in which the delay time required for processing on each terminal device is larger than the propagation delay time of the network, the application can be shared in real time.

Since the other operations are the same as those described in the operation example of the second embodiment, the description thereof is omitted here.

In the present embodiment, the identification number assigned in the generation order of the object is used as the identification information of the operation object of the processing / object identifier, but the identification representing the type of the object shown in the first embodiment. A combination of information and an identification number assigned in the generation order of the same type of target may be used as the operation target identification information.

Further, in the present embodiment, the identification number assigned in the generation order of the target is used as the identification information of the operation target of the process / target identifier, but it is assigned in the generation order of the dynamically generated operation target. It may be an identification number or an identification number assigned to a dynamically generated generation target of the same operation target as the identification information indicating the target type.

Embodiment 3. Next, a third embodiment of the present invention will be described with reference to FIGS. FIG.

Is a Nau application processing means.

FIG. 23 is a diagram showing a flow of processing when a dynamically generated operation target is generated by a teacher adding an annotation on an online text at a teacher terminal device during a lesson. FIG. 24 is a diagram showing the flow of processing on the student terminal device when it receives information regarding the generation of the operation target that is dynamically generated.
The operation performed when the process / target identifier corresponding to the operation target for which the process / target identifier corresponding to is registered is received is shown. Further, FIG. 25 is a flowchart showing the operation executed on the terminal device requested for the information necessary for the generation of the dynamically generated operation target.

Next, the operation will be described by taking as an example a class support system for supporting a class in an electronic classroom using hypertext as an online text. FIG.
In the configuration of 2, when the teacher adds an annotation on the online text screen during the lesson, the process shown in FIG. 23 is executed. The teacher uses the input means 2 to add an annotation to the online text that is an application (step S171). The input analysis unit 3 analyzes the operation performed by the teacher, and uses the application unit 5 to generate an annotation as a new operation target (step S172). The application processing means 5 processes
The newly created annotation as the operation target is registered in the target identifier holding means 9, and the information necessary for generating the target is sent to the operation target generation information determining means 22 (step S173). The operation target generation information determining unit 22 collects the information necessary for generating the target as the information to be transmitted to the other terminal device 6, transmits the information to the other terminal device 6 through the information communication unit 10, and the operation target generation information holding unit. 27
Is requested to hold the information necessary for generating the operation target (step S174). Operation target generation information holding means 27
Then, the information necessary for generating the operation target is registered and held in association with the identifier of the operation target (step S175).

On the other hand, the student terminal device 6 that has received the process / target identifier sent by the operation on the teacher terminal device 6
Then, the process shown in FIG. 24 is performed. First, the information communication unit 10 sends the process / target identifier sent via the network to the process / target identifier holding unit 9 (step S181). The processing / target identifier holding means 9 compares the information held by itself with the received processing / target identifier (step S182). If the received process / target identifier is not registered (step S183), the information communication unit 10 sends the request information of the information necessary for generating the operation target to the transmission side terminal 6 of the process / target identifier. And the information necessary for generating the requested operation target is received through the information communication unit 10 (step S184). Next, the processing / target identifier holding means 9 requests the application processing means 5 to generate the operation target, and registers / holds the processing / target identifier relating to the operation target generated by the application processing means 5 (step S185). When the above process is completed or the received process / target identifier is already registered in step (step S183), the operation target and the process of the application corresponding to the process / target identifier are specified, and the application is processed. Request processing to the application processing means 5 (step S18
6) Obtain the same execution result as the operation executed on the teacher's terminal device.

In FIG. 22, the terminal 6 requested by the other terminal device to generate information on the dynamically generated operation target performs the processing shown in FIG. First, the information communication unit 10 receives a request for sending information necessary for generating an operation target sent through the network (step S191). The information communication unit 10 sends the received request to the operation target generation information holding unit 27 (step S19).
2). The operation target generation information holding unit 27 determines the information necessary for generating the displayed operation target based on the requested operation target identifier, and returns it to the requesting terminal device through the information communication unit 10. Yes (step S193).

Here, if the generation information for the operation target dynamically generated is not received for some reason, the operation for the operation target cannot normally be processed on the receiving terminal side. When a process / target identifier that is not held as described above is received, the generation information for the operation target is requested to the sending terminal device of the process / target identifier, and the operation target is determined based on the returned generation information. By performing the process after the generation, even if the generation information is not sent for some reason, the operation can be continuously shared.

After that, when the dynamically generated operation target is operated, the application and the execution result thereof are shared by the method described in the first embodiment.

Since other operations are the same as those described in the second embodiment, the description thereof is omitted here.

Further, in this embodiment, when the process / target identifier related to the operation target is not held in the terminal device which has received the process / target identifier, the information necessary for generating the operation target is set to the process / target identifier. Although it is configured to request the transmission terminal of the target identifier, the identification information of the operator who generated the operation target is embedded in the process / target identifier, and the generation information of the operation target is generated. It may be configured to make a request to the person's terminal device.

[0069]

Since the present invention is configured as described above, the following effects can be obtained.

Since the information exchange between the terminal devices sharing the same application is performed by the combination of the identifier indicating the application process and the identifier indicating the operation target, the traffic amount on the transmission path can be reduced. There is an effect that the operation can be shared in real time.

Further, the information exchanged between the terminal devices sharing the same application is constituted by the character code as the identification number generated in the order of the operation target and the identifier representing the application process. The processing for identifying the operation target in each terminal device can be simplified, the processing time for operation sharing can be shortened, and real-time operation and execution result sharing can be performed between the terminal devices.

Further, since the identification information indicating the type of the operation target is added to the process / target identifier, even when the same process is performed for all of the specific operation targets,
The target identification information can be easily specified on each terminal device, and the target can be accurately identified for the operation.

Further, by using a special character string that matches all the identification numbers in the identification number portion of the identification number assigned to the identification information indicating the type of the operation target and the generation number of the operation target of the same type, the same operation target can be obtained. Since the same processing can be performed for all of the above, the processing for information exchange can be simplified compared to the case where the processing / target identifier is sent to each operation target each time, and the operation and The execution results can be shared in real time.

When an operator dynamically creates an operation target when operating an application, the information necessary for generating the operation target is sent to the terminal device of another operator.
Since the same operation target can be dynamically generated also in the receiving terminal device, there is an effect that the operation contents with a high sense of presence can be shared in real time on a plurality of terminal devices.

Since the processing / target identifier is configured to add an identifier indicating whether or not the operation target is a dynamically generated target, the operation target dynamically generated among all the operation targets. Can be easily specified, and an operation target newly generated at the end of the application can be saved, and processing for all dynamically generated operation targets can be facilitated.

Further, since the identifier of the operator who generated the operation target is incorporated in the process / target identifier, when a new operation target is individually created for an application shared by a plurality of operators. Also in, it is possible to specify the creator of each operation target,
This has the effect of facilitating the management of the operation target for each operator.

Further, the process / target identifier for the dynamically generated operation target is generated only by the terminal device that has performed the operation, and is processed for other terminal devices together with the information necessary for generating the operation target. Since the target identifier is sent, it is possible to prevent inconsistency between the operation targets among a plurality of terminal devices.

Further, when the process / target identifier is not registered in the receiving terminal device of the process / target identifier transmitted from the operator terminal device, the information necessary for generating the operation target is stored in the process / target identifier. -Since the target identifier is requested to the terminal device that has been sent, and the operation target is newly generated and registered based on the returned information, the operation target that is dynamically generated between the terminal devices is Also has the effect of eliminating inconsistencies.
