Description

Mindmap system for colabaration and method about

The present invention relates to a joint mind map creation system and a method of providing the same. More specifically, a plurality of creator terminals connected through a network centered on a mind map server participate in a conference room at the same time and share a common topic for a meeting topic in real time. The present invention relates to a joint mind map system and method for creating a mind map.

The 21st century is an era of creativity. Creative ideas of individuals or groups can always come to mind at any time, but most of them disappear because of environmental constraints.

MindMap is a new method of learning and memory developed by Tony Buzan, a British student in the early 1970s. Mind Map means 'Map of Thought', thinking and creativity by unfolding the thoughts of people with random order and multi-dimensional characteristics in the middle of paper in a radial form with key words, images, colors, symbols, symbols, etc. It is a brain development technique / brain usage technique that increases strength and memory. The different functions of the human left and right brains, discovered by Roger Sperry's team at the same time, were a good basis for supporting Buzan's mind map theory.

Roger Sperry's team published a study of the brain's brain cortex in the late 1960s. His work on the left and right brains laid the groundwork for brain research, and his successors, Onstein, Seidel and Bloch, developed and complemented his work. Although each hemisphere dominates certain areas and activities of the brain, basically both hemispheres control all areas of the brain. The mental skills bisected by Roger Sperry were virtually evenly distributed throughout the brain cortex. Michael Bloch wrote in his paper, Tel / Syn, that if we define ourselves as a person in the right brain or a person in the left brain, it limits our ability to develop new abilities. Said.

The mind map is organized in a way that the brain comfortably accepts and spills information. There is not much you need to do to get a mind map. Anyone can easily do it with the same number of highlighters, such as the A4 or A3 blank paper and three or four colored pens.

By using the left brain where logic and vocabulary are the main functions, and the right brain where color and form are the main functions, you only need to draw your thoughts on paper in a proper way. Thousands of people are enjoying this extraordinary effect on their mind maps at work, at school and at home.

Conventionally, in order to use such a mind map, a paper and a pen were needed, and a mind map prepared in this way had to be kept separately and kept, and many problems such as the possibility of additional deletion of thoughts were not possible.

In order to solve this problem, a technology for creating a mind map using a personal computer and storing the created mind map in a personal computer has been developed and used more conveniently.

However, the technology for creating a mind map using such a personal computer has a limitation in that it is possible to simply construct the mind map of individual ideas.

On the other hand, in recent years, the importance of collective intelligence activities is increasing day by day, and as part of such collective intelligence activities, meetings, discussions and discussions are being actively conducted offline. In addition, due to the development of the Internet technology, a technology that can be used for meetings, discussions, and discussions that have been conducted offline, beyond the constraints of time and space, and online meetings has been developed and serviced. However, when using the online conference technology, it is difficult to store the contents of the meeting, and even if the contents of the meeting are stored as a text file, the recording of the ideas or the storage itself leads to the fact that only the fragmentary and meaningless ideas are listed. In other words, in the case of using the online meeting technology according to the prior art, although it is possible to store the ideas of a plurality of meeting participants, it is possible to visually structure the correlation of the many collected ideas and reprocess them into information with greater meaning and value. There was no problem.

The present invention, in order to solve the problems of the prior art as described above, a plurality of creator terminals connected via a network around the mind map server to participate in one meeting room at the same time to create a joint mind map for the meeting topic in real time The purpose of the present invention is to provide a common mind map preparation system and a method of providing the same.

Alternatively, in the above-described joint mind map creation method, when the mind map server determines whether to maintain synchronization in the step (d5), if there is an author terminal determined to have lost synchronization by transmitting an abnormal CRC value, the abnormal CRC Only the creator terminal transmitting the value is prohibited from editing the joint mind map, and in the step (d6), the mind map server transmits the normal CRC value to the creator terminal transmitting the abnormal CRC value. Map configuration information transmitted from the creator terminal having time is stored in time series, and in the step (d7), the mind map server stores the map configuration information stored in time series in the step (d6) when normal co-mind map data transmission is completed. Transmitting the abnormal CRC value to the originator terminal, and transmitting the abnormal CRC value in step (d8). The mobile station recovers the synchronization of the lost co-minded map using normal co-minded map data transmitted from the mind map server, and uses the time-stored map configuration information transmitted from the mind-map server. After updating the mind map, it may be configured to allow the creator to edit the co-mind map.

As described above, according to the joint mind map preparation system and method according to the present invention, a plurality of creator terminals connected through a network centered on a mind map server participate in a conference room at the same time in real time. The advantage is that you can create a joint mind map for.

In addition, according to the present invention, the synchronization of the joint mind map of all the creator terminals participating in the common mind map may be maintained by periodically determining the synchronization of the creator terminal and restoring the synchronization of the lost creator terminal. There is an advantage.

In addition, according to the present invention, it is possible to improve the processing speed of the overall system by determining whether to allow editing of objects on the joint mind map in each creator terminal through distributed processing in order to maintain consistency of the joint mind map preparation system.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the joint mind map creation system and its providing method.

Definitions of terms used below are as follows.

"Creator terminal" refers to all the terminals (founder terminal, participant terminal) participating in the joint mind map is loaded with the joint mind map client program according to the present invention.

'Establisher terminal' refers to a terminal requesting the establishment of a meeting room for creating a co-minded map according to the present invention with a mind map server according to an operator's operation, and a 'participant terminal' is connected to the mind map server. Means a terminal that participates in a meeting room established on request and performs a joint mind map. The 'setter terminal' and 'participant terminal' are divided based on the subject of the request for opening a meeting room. There is no difference in function or authority.

'Administrator terminal' and 'general terminal' are classified according to authority in the process of creating a co-minded map, and 'administrator terminal' is a co-mind of the creator with a specific screen name (ID) set by the establisher's operation. The authority to edit all objects on the map is granted, and the authority to collectively manage / execute various privileges of the meeting room for creating the joint mind map, such as whether to display the author ID, select object colors by author, and grant permission to participate in the meeting room. The term 'general terminal' refers to a terminal to which only editing authority of a lower object of a predetermined level is granted among objects on a co-mind map.

'Level' refers to a branching order sequentially given according to the number of branches branched in a tree form based on the central object on the common mind map as one level. That is, an object formed on a branch branched from the central object once has a two-level branching order, and an object formed on a branch branched two times has a three-level branching order.

'Basic mind map' means a mind map that is the basis for creating a co-mind map, which is created by the establisher's terminal and uploaded to the mind map server and downloaded to the participant terminals participating in the conference room. 'Mind map' means a mind map that is created based on the operation of all creator terminals participating in the conference room based on the 'basic mind map'.

1 is a schematic structural block diagram of a joint mind map preparation system according to an embodiment of the present invention. Hereinafter, with reference to the accompanying Figure 1 will be described in detail a joint mind map creation system according to an embodiment of the present invention.

As shown in FIG. 1, the joint mind map preparation system according to an exemplary embodiment of the present invention may include at least one creator terminal 100, a network 130, and a mind map server 140.

The creator terminal 100 is equipped with the joint mind map client program 200 according to the present invention, and connects to the mind map server 140 connected through the network 130 according to the author's manipulation to create a joint mind map. The creator terminal 100 may be implemented using a personal information communication device having a data communication function through a network 130 such as a personal computer, a notebook computer, a PDA, and the like. The creator terminal 100 may perform a function of generating an individual mind map by receiving an individual operation of the author in an offline state, and a function itself for generating an individual mind map according to the operation of the creator adopts a known technique. As such, further description will be omitted.

Meanwhile, the creator terminal 100 according to the present invention may be classified into a establisher terminal 110 and a participant terminal 120 in connection with opening a conference room.

The establisher terminal 110 generates a basic mind map according to a conference topic to create a co-mind map according to the establisher's operation, and accesses the mind map server 140 to request the establishment of a conference room with a specific theme. At this time, the basic mind map may be configured to include one first-level center object or one first-level center object and at least one lower level object, and the basic mind map may include a common mind map. It becomes the base map. In addition, the establisher terminal 110 uploads the basic mind map generated in the process of requesting the establishment of the conference room to the mind map server 140 to the mind map server 140, and at the same time, various setting information (name of the conference room, Password, meeting room participant information, class setting of author terminal, administrator authority setting, meeting opening time, meeting time, etc.) are set. When the meeting room establishment setting is completed, the mind map server 140 opens the meeting room to allow the participant terminal 120 to participate in the meeting room. At this time, more preferably, the mind map server 140 according to the present invention uses the conference room participant information (e-mail address, mobile number) transmitted from the establisher terminal 110 (meeting topic, conference establishment time, etc.). ) Can be configured to notify the creator set as a participant by email or SMS. Since the technology itself for notifying the conference setting report using e-mail or SMS uses a known technology, a detailed description thereof will be omitted.

The participant terminal 120 is connected to the mind map server 140 through the network 130 according to the participant's manipulation, and the participant terminal 120 participates in the conference room in which the participants want to participate. The mind map server 140 transmits a list of conference rooms opened to the participant terminal 120 when a plurality of conference rooms are opened, and the participant desires a list of conference rooms displayed on the participant terminal 120. Select to participate. If the password is set in the meeting room, the participant may enter the set password by operating the participant terminal 120 to participate in the corresponding meeting room. When participant authentication of the participant terminal 120 is completed, the mind map server 140 transmits the stored basic mind map transmitted from the establisher terminal 110 to the participant terminal 120 and transmits the participant's information to the establisher terminal 110. And another participant terminal 120 to be transmitted. Through this process, a plurality of participant terminals 120 participate in the conference room opened at the request of the establisher terminal 110, and when the meeting start time is set or there is a request for starting a meeting from a manager terminal set to a manager level. The joint mind map creation process by the establisher terminal 110 and the plurality of participant terminals 120 participating in the conference room is started.

The creator terminal 100 according to the present invention basically creates / edits a joint mind map based on the basic mind map displayed on the creator terminal 100 according to the manipulation of the creator's input device (keyboard, mouse). The common mind map edits are generated as map configuration information (message for data communication) and transmitted to the mind map server 140. At this time, the joint mind map generation / edit itself on the creator terminal 100 is performed in the same manner as the generation / editing of the individual mind maps on the offline. That is, the joint mind map generation / editing according to the creator's manipulation on the creator terminal 100 is performed in the same manner as the generation / editing of individual mind maps, but the mind map for the creation of the joint mind map through the network 130 is performed. The edited content is generated as map configuration information and transmitted to the mind map server 140. The mind map server 140 receives the map configuration information transmitted from the sender creator terminal (the creator terminal transmitting the map configuration information), stores the map configuration information in the mind map database 142, and at the same time participates in another meeting terminal (receiving). The map configuration information received from the side creator terminal) is transmitted. The other author terminal 100 receives and interprets the map configuration information transmitted from the mind map server 140, and then map configuration information interpreted in the data structure of the common mind map displayed on the other author terminal 100. The joint mind map is updated to reflect this. The co-mind map according to the present invention is created through the generation / transmission of the map configuration information of the one-side creator terminal 100, the transmission of the mind map server 140, and the reception / interpretation of the other creator terminal 100.

The mind map server 140 receives a basic mind map transmitted from the establisher terminal 110 to open a conference room, and transmits the received basic mind map to the participant terminal 120 participating in the established conference room. Receive the map configuration information transmitted from the creator terminal 100 participating in the and transmits to the other creator terminal 100 participating in the conference room. In order to perform such a function, the mind map server 140 according to the present invention is equipped with a joint mind map server program 220, and a creator who accesses a web page for opening a conference room and joining a conference room through the network 130. It is provided to the terminal 100, and relays the transmission and reception of the map configuration information between the creator terminal participating in the conference room. In addition, the mind map server 140 according to the present invention includes a mind map database 142 in which a basic mind map and a co-mind map are structured and stored. Detailed configuration and functions of the above-described common mind map server program 220 will be described later with reference to FIG. 2B.

On the other hand, more preferably, the creator terminal 100 according to the present invention may be set according to the editing authority according to the level of the co-mind map object according to the setting of the establisher. In this case, the editing may include actions such as deleting, moving, changing contents, and creating sub-objects. According to the invention, at least one or more of editing, deleting, moving, changing contents, and creating sub-objects may be restricted according to the grade. The permission may be determined according to the editing authority granted to the terminal. Hereinafter, since the deletion of the object and the movement of the object will be described based on the embodiment prohibited according to the editing authority, the "prohibition of editing" should be understood as the "prohibition of moving or deleting the object." However, the scope of the present invention is not limited thereto, and the editing scope other than the "prohibition of moving or deleting an object" according to the editing authority will belong to the scope of the present invention.

In addition, the grade may be set in various manners and grades as needed, and as an example, may be configured to set each creator terminal 100 to the administrator terminal and the general terminal grade. The administrator's terminal is an author's terminal with a specific screen name (ID) set according to the establisher's operation, and is authorized to edit all objects on the co-mind map. Refers to a terminal that is authorized to collectively manage / execute various privileges of a meeting room for creating a joint mind map such as granting authority. On the other hand, the general terminal is given only the editing authority of the lower level object of the preset level among the objects on the co-mind map. Here, 'level' means a branching order sequentially given according to the number of branches diverged in a tree form based on the central object on the common mind map as one level. For example, if the editing authority of the general terminal is 3 levels or less, the administrator terminal can edit / delete all objects on the co-mind map, but in the case of the general terminal, objects of 3 levels or less formed on branches branched twice from the central object Only editing / deleting is allowed. The level of the creator terminal is the meeting room setting information (name of the meeting room, password, meeting room participant information, rating setting of the creator terminal, administrator authority setting) transmitted from the establisher terminal 110 to the mind map server 140 when the meeting room is opened. , Meeting establishment time, meeting time, etc.), and the grade information is transmitted and stored to all creator terminals 100 participating in the conference room.

Meanwhile, the method of determining whether to allow editing of the joint mind map according to the terminal grade may be implemented in various ways. In the first method, the mind map server 140 interprets the map configuration information transmitted from the creator terminal 100 and includes edit information that does not match the set level (for example, the editing authority of the general terminal is 3 levels or less). In the case where the information is transmitted from the general terminal when the editing information is transmitted from the general terminal), the mind map server 140 outputs an error message to the sender creator terminal 100 and disallows editing of the co-mind map. Can be configured. This method is a way to centrally manage whether to allow editing according to the authority level of the author terminal 100 in the mind map server 140, the mind map server 140 instead of reducing the burden on the author terminal 100 side There may be a drawback that the responsiveness of the entire system may be lowered due to the increased burden on the system. As a second method, there may be a management method of allowing object editing through distributed processing. That is, the rating information of the author terminal 100 is stored in each author terminal 100, and each author terminal 100 determines whether the editing is within the authorized permission to edit the co-mind map according to the author's operation. In the case of not editing, the error message is output from the creator terminal 100 itself and the editing of the co-minded map is not allowed. In this way, if the editing permission according to the permission level is determined by decentralized processing, since each author terminal 100 determines whether to allow editing itself, the burden of the mind map server 140 may be reduced, thereby improving the responsiveness of the entire system. There is an advantage that it can. On the other hand, such a distributed processing method can be applied in the process of maintaining the coherence of the common mind map, which will be described later with reference to FIG.

On the other hand, the joint mind map creation system according to the present invention may be configured to set the meeting time required for the joint mind map creation. That is, in order to overcome the shortcomings of an overly long meeting, the establisher operates the establisher terminal 110 to set a time (meeting time) at which the joint mind map is created when the conference room is opened, and includes the mind map in the conference room setting information. The server 140 may be transmitted to the server, and the mind map server 140 transmits an alert message to each creator terminal 100 before the end of the meeting time, and when the meeting time ends, forcibly creates a co-mind map through the meeting room. Will end. Such a meeting time can be shortened or extended by a creator set as an administrator by operating a manager terminal according to a meeting progress time.

In addition, the joint mind map creation system according to the present invention may be configured to support the ID toggle function to display or not display the ID of the creator who created the object to each object on the joint mind map. This function is to overcome the disadvantage that subordinates cannot freely express their ideas due to the burden of position in meeting rooms where authors with various positions participate. When ID display function is turned off, the co-minded map shows the author's ID. Only the input objects are displayed without being displayed, making up the common mind map. On / off of this ID toggle function, the first establisher operates the establisher terminal 110 and transmits the ID toggle setting to the mind map server 140 including the conference room setting information, and the received ID toggle setting is performed by each participant. It is transmitted to the terminal 120 to be referenced when outputting the common mind map displayed on each creator terminal 100. In addition, during the conference, the manager operates the manager terminal to turn on / off the ID toggle function so that the author ID is output to all the author terminals 100, or the author ID is output only to the manager terminal or the author ID is displayed. The setting may be adjusted so that all writers are not output to the terminal 100.

Furthermore, the joint mind map preparation system according to the present invention is more preferably configured to set a specific color, typeface, etc. for each author for visual and intuitive classification of each creator. For example, the establisher manipulates the establisher terminal 110 and assigns red to the author A by the author, yellow to the author B, and blue to the author C to set the author-specific setting information for the conference room. When the information is transmitted to the mind map server 140, the creator-specific setting information is transmitted to all the creator terminals 100 participating in the conference room, and is stored and referred to when creating / outputting the joint mind map. That is, the object on the co-minded map created by the author A on each author terminal 100 is displayed as a red polygon (the color of the letter can also be set), and the object on the co-minded map created by the author B is a yellow polygon (letters). Colors can also be set), and objects on the co-mind map created by the author C are displayed as blue polygons (letters can also be set). Therefore, each author can identify the color of each object of the co-mind map represented by the color set for each creator displayed on his or her creator terminal 100 to visually and intuitively distinguish the creator of the object. Of course, such creator-specific setting information may be changed by the creator set to the administrator level by operating the administrator terminal during the meeting, and the setting information, if the setting information is changed via the mind map server 140 It is transmitted to each creator terminal 100 so as to be referred to when creating / outputting a joint mind map.

On the other hand, in the collaboration system interconnected by the creator terminal 100 through the network 130, it is very important to secure the synchronization between the creator terminal by synchronizing the collaboration data (Synchronization). That is, when a problem occurs temporarily in the data communication due to the line state of the network 130 itself, the communication state of each creator terminal 100, etc., the creator in which the data communication state is in a normal communication with the creator terminal 100. There is a problem that synchronization occurs due to a difference in the co-mind map data between the terminals 100, and to solve this problem is an important technology to secure the integrity of the collaboration system through the network. As a method for securing synchronization as described above, first, the mind map server 140 determines the communication status with all the creator terminals 100 connected in real time, and when a data communication with some creator terminals 100 occurs. The system may be configured to resume transmission and reception of map configuration information for creating a co-minded map after restoring the communication failure, after prohibiting data transmission and reception of all creator terminals 100 until the communication failure is recovered. However, when the system is configured in this manner, since the mind map server 140 must always determine and monitor the communication status with all creator terminals 100, the burden on the server is increased and the responsiveness of the entire system is lowered. If a failure occurs in 100, the entire system must be stopped.

Therefore, more preferably, the co-minded map creation system according to the present invention is a kind of synchronization determination data for confirming the synchronization of the co-minded map data from the mind map server 140 to each creator terminal 100 according to a set period It may be configured to determine the synchronization of the joint mind map data using the synchronization determination data generated and transmitted by each creator terminal 100 requested and received. This will be described in more detail below.

The mind map server 140 according to the present invention stores basic mind map information constituting the co-mind map and map configuration information transmitted to each creator terminal 100 via the mind map server 140 (co-mind Although the map is constructed and not output through the display unit (not shown), the data structure of the common mind map of the current conference room, which is actually interpreted and reflected in the basic mind map, is the mind of the mind map server 140. It may be configured to be updated in real time in the map database 142.), When the preset synchronization determination cycler arrives, the mind map server 140 requests the synchronization determination data to all connected creator terminals 100, and at the same time, The synchronization determination data is generated based on the common mind map data structure of the current conference room stored in the map database 142. Each creator terminal 100 generates the synchronization determination data based on the data structure of the common mind map currently displayed on the creator terminal 100 according to the synchronization determination data request of the mind map server 140. The mind map server 140 compares the synchronization determination data transmitted from each creator terminal 100 with the normal synchronization determination data generated by the mind map server 140 to maintain synchronization. Will be judged. In this case, various data reliability check algorithms may be applied to a method for generating synchronization determination data. In particular, an algorithm for checking data reliability in data communication may be applied. That is, the algorithm for determining whether to maintain synchronization according to the present invention is applied to the method for checking the reliability of data in the data communication, mind map configuration information transmitted through the mind map server 140 to each creator terminal By comparing the mind map configuration information received at (100) is configured to determine whether to maintain synchronization. As a simple error detection method, the parity bit method and the error detection method by check-sum may be adopted as the data reliability checking method. However, the parity bit method cannot detect when two or four bits of data are changed at the same time. The check-sum method uses an error even if an error occurs from one byte to +1 and another byte to -1. Since there is a disadvantage that is not detected, the joint mind map preparation system according to the present invention is more preferably configured to check the synchronization of the joint mind map data using the CRC value. The cyclic redundancy check (CRC) value is a kind of error detection method for verifying the reliability of data in the original serial transmission. The CRC method is characterized by high reliability, low overhead for error detection, and very good performance for error detection including random error and burst error. Two kinds of CRC methods are commonly used. CRC16 values are used for simple applications such as one-chip microprocessors, and CRC32 values are used when more accurate error detection is required. In the present invention, it is preferable to configure whether to maintain synchronization using the CRC32 value. Meanwhile, the co-mind map data for calculating the CRC32 value may be variously selected as necessary. In other words, when the most detailed synchronization judgment is desired, the CRC32 value may be calculated based on all the data constituting the joint mind map, or the data constituting the joint mind map according to the degree of accuracy of the synchronization judgment. It may be configured to calculate the CRC32 value based on some data (the number of objects on the joint mind map, the number of information included in the joint mind map, etc.).

In the above process of determining whether to maintain the synchronization, when the specific CRC32 value is transmitted from the specific creator terminal 100, the mind map server 140 determines that the synchronization of the corresponding creator terminal 100 is lost, and restores the synchronization. The process will be performed. The joint mind map preparation system according to the present invention may be configured to perform a process of restoring synchronization in two different ways.

In the first method of restoring synchronization, when there is an author terminal 100 that transmits an abnormal CRC32 value, the mind map server 140 prohibits the creation of a co-mind map of all creator terminals 100 participating in the conference room. After the synchronization of the creator terminal 100 that transmits the abnormal CRC32 value is restored, it may be configured to allow the creation of the common mind map of all the creator terminals 100. That is, the mind map server 140 compares the CRC32 value generated and transmitted by each creator terminal 100 with the CRC32 value generated by the mind map server 140, and if an error occurs, all connected creator terminals 100. A command to prohibit the creation (edit) of the common mind map is transmitted to each creator terminal (100). Each creator terminal 100 receives a co-mind map creation prohibition command sent from the mind map server 140, and guides the message through the display unit (not shown) until the co-mind map creation prohibition is released. Will be disallowed to create a co-minded map. At the same time, the mind map server 140 requests normal joint mind map data to the creator terminal 100 that has transmitted the normal CRC32 value, and then sends the normal joint mind map data from the creator terminal 100 which has transmitted the normal CRC32 value. Data is received and transmitted to the creator terminal 100 that has transmitted the abnormal CRC32 value. If the mind map server 140 is configured to store normal common mind map data in accordance with the present invention, the mind map server 140 does not separately request normal common mind map data, but the normal common mind map stored in the database. The data may be configured to be transmitted to the creator terminal 100 that has transmitted the abnormal CRC32 value. When the creator terminal 100 that transmits the abnormal CRC32 value receives all the normal co-mind map data and updates the co-mind map, the mind map server 140 prohibits the creation of the co-mind map of all connected creator terminals 100. Will be released. Of course, in this case, in order to determine whether the synchronization of the creator terminal 100 that lost synchronization is completely restored, the creator terminal 100 that transmits the abnormal CRC32 value receives normal joint mind map data and updates the updated joint mind map. The CRC32 value may be transmitted to the mind map server 140, and the mind map server 140 may perform the process of comparing the transmitted CRC32 value once again to determine whether to recover the synchronization.

In the second method of restoring synchronization, when there is an author terminal 100 that transmits an abnormal CRC32 value, the mind map server 140 creates a joint mind map only for the creator terminal 100 that transmits an abnormal CRC32 value. It may be configured in such a manner that the editing is prohibited and the creation / editing of the joint mind map of the creator terminal 100 having transmitted the remaining normal CRC32 value is allowed. In addition, a method of requesting normal common mind map data and transmitting the abnormal CRC32 value to the creator terminal 100 that has transmitted the abnormal CRC32 value, and outputting a guide message on the creator terminal 100 that has transmitted the abnormal CRC32 value itself are the same as the first method. Therefore, detailed description is omitted. In this way, when the joint mind map creation system is configured, the joint mind map creation / editing of the creator terminal 100 having normal joint mind map data is possible, so that there is an advantage that a smoother mind map creation process can be performed. . The map configuration information generated while the common mind map creation / editing of the creator terminal 100 that transmits the abnormal CRC32 value is prohibited and relayed through the mind map server 140 is temporarily stored in the mind map server 140 in time series. The creator terminal 100 that transmits the abnormal CRC32 value downloads all of the normal joint mind map data, completes the update of the joint mind map, and then collectively transmits the abnormal CRC32 value from the mind map server 140. 100). The mind map server 140 downloads both the normal co-mind map data and the temporarily stored map configuration information by updating the co-mind map after the creator terminal 100 having transmitted the abnormal CRC32 value and then updates the co-mind map. By allowing the creation / editing of the joint mind map, the synchronization recovery process is terminated.

Meanwhile, in order to solve the dependency of the data structure of the collaboration data in a collaboration system such as the present invention, in which a creator terminal 100 is interconnected through a network 130 and performs collaboration by focusing on a collaboration server. Software inter-locking processing is a problem that must be solved in order to maintain the coherence of collaborative data. That is, when a specific object on the co-mind map being edited first selected by a specific author terminal 100 is selected and deleted / edited again by another author terminal (for example, A author creates an object called 'schedule' of two levels). If a B author selects and deletes a 2nd level 'schedule' object while inputting a new level 3 object that is branched from an object called 'scheduled', the data structure is inconsistent and there is an error in collaboration. Therefore, when a specific object on the co-mind map is being edited first selected by the specific creator terminal 100, there is a need to prohibit editing of the corresponding object of another creator terminal 100 connected through the network 130. Looking at the consistency maintaining method according to the prior art, the centralized management method through the collaboration server has been used. That is, in reality, each terminal unconditionally transmits the editing data for the collaboration according to the author's operation to the collaboration server, and the editing data for the collaboration according to the author's manipulation in the collaboration server side breaks the consistency of the collaboration. In the case of editing data that breaks the consistency, an error message is sent to the terminal that transmitted the editing data, and a technique of maintaining the consistency is not applied to the collaborative data structure. However, when coherence is centrally managed in the collaborative server in this manner, there is a disadvantage that it becomes practically impossible to collaborate in real time because the responsiveness of the whole system is deteriorated due to excessive burden on the server. In order to solve the problems of the prior art, the joint mind map preparation system according to the present invention allows the creator terminal 100 to determine whether to allow editing of an object to maintain the consistency of the collaborative data. It is configured to improve the responsiveness of the. That is, in the system according to the present invention, the mind map server 140 does not determine whether to allow editing of a specific object on the joint mind map, but directly determines the object in the author terminal 100 so that editing is not possible. It is configured to immediately output an error message and not transmit the corresponding edit information (map configuration information) to the mind map server 140.

Here, the editing may include actions such as deleting, moving, changing contents, and creating a sub-object, as described above. According to the invention, it may be configured to determine whether to allow at least one or more of editing, deleting, moving, changing contents, and editing of sub-objects. It may be configured to determine whether editing is allowed. In this manner, when the collaborative mind map creation system according to the present invention is configured to determine whether to allow deletion or movement during editing of an object in order to maintain coherence of the collaborative data, each author terminal 100 is a creator. When deleting or moving a specific object on the common mind map by operating the terminal 100, it is determined whether the deletion or movement of the corresponding object is allowed, and the creator manipulates the creator terminal 100 to make a specific object on the common mind map. When changing the contents of or creating a sub-object, it is configured to allow the change of the content or the creation of the sub-object without determining whether to allow it.

In order to perform such a function, the creator terminal 100 according to the present invention uses the selected object information (hereinafter referred to as 'lock information') when the specific object of the co-mind map is selected according to the manipulation of the creator mind map server 140. ), The mind map server 140 transmits the received lock information to all other author terminals participating in the collaboration, and thus the editing of the corresponding object of another author is not allowed. That is, when one creator terminal 100 first selects an object that is not selected by another creator terminal 100, the lock information according to the selection of the object participates in the meeting room via the mind map server 140. It is transmitted to all author terminals 100 and stored in each author terminal 100. When another author selects and edits a specific object for editing a co-mind map, the other author terminal 100 stores the stored lock information. Whether to allow editing of specific objects selected by other authors (when it is configured to judge only deletion or movement of selected objects during editing actions, or not to edit (delete / move) only when there is an operation to delete or move objects) To allow content modification or creation of sub-objects without judging whether or not to allow modification of the content or creation of sub-objects). It is composed. In addition, when the editing of the object is completed or the selection is released in the creator terminal 100 that transmits the lock information, the creator terminal 100 may refer to object information according to deselection or editing completion (hereinafter referred to as 'release information'). And the mindmap server 140 transmits the received release information to all other author terminals 100 participating in the collaboration to allow the other object to be edited by the mindmap server 140. do. Detailed description of the dispersion processing method for maintaining the consistency according to the present invention will be described later with reference to the accompanying FIG.

Figure 2a is a block diagram representing the logical configuration of the creator terminal of the joint mind map preparation system according to an embodiment of the present invention. Hereinafter, a detailed configuration and function of the creator terminal for performing the function described above with reference to FIG. 2A will be described.

As shown in FIG. 2A, the creator terminal 100 according to the present invention is equipped with a joint mind map client program 200 logically implemented, and the joint mind map client program 200 includes a communication module 210 and a joint. The mind map control module 212 and the map generation module 214 may be included.

The communication module 210 controls a communication unit (not shown) such as a network card provided in the creator terminal 100 to connect to the mind map server 140 through the network 130 through the network 130 to establish a socket method. By using the mind map server 140 to perform data communication. That is, the communication module 210 according to the present invention transmits the map configuration information according to the input of the creator to the mind map server 140 in the process of creating the co-mind map, and the other creator terminal 100 through the mind map server 140. Receive map configuration information transmitted from).

The common mind map control module 212 performs a function of controlling the creation / editing of the common mind map as a whole. That is, the joint mind map control module 212 according to the present invention may be selected by the author with reference to authority level (administrator level or general level) information for each author stored in the creator terminal 100 or lock / release information of a specific object. It is determined whether to allow editing of a specific object on the common mind map to be edited. When the creator selects an object allowed to be edited by manipulating the terminal, the collaborative mind map control module 212 generates map configuration information according to the collaborative mind map creation / editing on the author terminal 100 according to the author's input. By outputting to the communication module 210 to transmit to the other author terminal 100 through the mind map server 140 to function to be able to perform a joint mind map creation. In addition, the map generation module transmitted from the other author terminal 100 and received via the mind map server 140 is interpreted as information for creating / editing the actual co-mind map on the author terminal 100. 214).

The map generation module 214 is responsible for managing the actual data structure of the joint mind map on the creator terminal 100. That is, the map generation module 214 may operate the input device (not shown) such as a keyboard and a mouse connected to the creator terminal 100 to create / edit a joint mind map displayed on the creator terminal 100. In the case of inputting an operation, the contents of the joint mind map displayed on the creator terminal 100 are created / edited accordingly, and the contents of the joint mind map control module 212 are output to the aforementioned joint mind map control module 212. The contents of the joint mind map displayed on the creator terminal 100 are created / edited according to the analyzed map configuration information output from the map control module 212. That is, the basic function itself of the map generation module 214 according to the present invention performs a function substantially similar to a single mind map creation program installed in a personal computer. The difference is the common mind map control module 212 according to the present invention. It is configured to work in conjunction.

Figure 2b is a block diagram representing the logical configuration of the mind map server of the joint mind map creation system according to an embodiment of the present invention. Hereinafter, a detailed configuration and function of the mind map server for performing the above functions will be described with reference to FIG. 2B.

As shown in FIG. 2B, the mind map server 140 according to the present invention is equipped with a logical mind map server program 220 logically implemented, and the joint mind map server program 220 is a server communication module 222. It may include a shared map control module 224, a map generation module 226, a shared map maintenance module 228, a server management module 230, a database control module 232, and a common mind map database 142. .

The server communication module 222 controls the communication unit (not shown) of the mind map server 140 to create / maintain a connection with at least one or more creator terminals 100 connected through the network 130, and the creator terminal 100 Receives the map configuration information transmitted from) and transmits to the other author terminal (100). That is, it performs a function of relaying transmission and reception of map configuration information between a plurality of creator terminals 100 connected through the network 130. In addition, the server communication module 222 according to the present invention includes at least one sub-server communication module (not shown) connected to the communication module 210 of the creator terminal 100 in a one-to-one socket manner to perform one-to-one data communication. It is possible to create, maintain / release / monitor the connection with each creator terminal 100 through each sub-server communication module.

The server side common mind map control module 224 and the server side map generation module 226 are configured to perform functions substantially similar to the above-described creator terminal side mindset map control module 212 and the terminal side map generation module 214. do. That is, the map configuration information transmitted from the sender creator terminal through the server communication module 222 is interpreted and output to the server-side map generation module 226, and the server-side map generation module 226 is a server-side joint. The joint mind map information stored in the mind map database 142 is updated according to the analyzed map configuration information output from the mind map control module 224.

The common mind map maintenance module 228 is a module for maintaining the synchronization of the common mind map data of each creator terminal 100 constituting the joint mind map preparation system according to the present invention as described above. First, the common mind map maintenance module 228 stores a basic mind map transmitted from the establisher terminal 110 together with the request for establishing a conference room in the mind map database 142, and requests a participant terminal 120 to join the established conference room. Send the basic mind map stored in), and in the process of creating a co-minded map, create and update the co-minded map based on the stored default mind map by reflecting the map configuration information generated by each creator terminal (100). 142). In addition, when the common mind map maintenance module 228 according to the present invention arrives at a predetermined synchronization determination cycle, the mind map database requests a CRC 32 value for the current common mind map data to all connected creator terminals 100. Based on the common mind map data structure of the current conference room stored at 142, a reference CRC 32 value for determining synchronization is generated. When the CRC 32 value for the current common mind map data stored in each creator terminal 100 is transmitted from each creator terminal 100, the common mind map maintaining module 228 may transmit the reference CRC 32 value and the respective CRC 32 values from each creator terminal 100. It is determined whether the creator terminal 100 maintains synchronization by comparing the transmitted CRC 32 values. As described above, when there is an author terminal 100 that transmits an abnormal CRC 32 value in determining whether to maintain synchronization, the co-mind map maintenance module 228 determines that the synchronization of the corresponding creator terminal 100 is lost. Normal common mind map data is transmitted to the corresponding creator terminal 100 to control to reconstruct the common mind map. Since the detailed description of the synchronization determination and synchronization recovery function of the common mind map maintenance module 228 has already been described above, a detailed description thereof will be omitted.

The server management module 230 collects the mind map server-side status information (communication status, status of the creator terminal connected through the network, etc.) and provides it to an external management interface on a server manager terminal (not shown). The operation of the mind map server is controlled according to a control command input through a management interface output on the terminal. Since the server management module 230 itself adopts a known technology for a server management program, a detailed description thereof will be omitted.

 On the other hand, the mind map database 142 stores the basic mind map transmitted from the establisher terminal 110 at the time of request for establishment of the conference room, and after the start of the meeting to create a co-mind map, other minds from each creator terminal based on the basic mind map. The joint mind map generated / updated by reflecting the map configuration information transmitted to the creator terminal is structured and stored. The database control module 232 controls the storage and output of the basic mind map stored in the mind map database 142 and the joint mind map data based on the basic mind map.

3 is a flowchart illustrating a process of opening a meeting room and starting a meeting of a joint mind map preparation system according to an exemplary embodiment of the present invention. Hereinafter, with reference to Figure 3 will be described in detail the process of opening the meeting room and the start of the meeting according to the present invention.

First, the establisher terminal 110 equipped with the co-mind map client program 200 generates a basic mind map that is the subject of the co-mind map according to the operation of the establisher, and stores the generated basic mind map (S300). At this time, the process of generating the basic mind map itself is the same as generating the mind map using a single mind map creation program mounted on a personal computer, etc., the information of the basic mind map according to the present invention is interpreted in the participant terminal 120 The map configuration information can be generated and stored.

When the basic mind map generation / save is completed, the establisher terminal 110 connects to the mind map server 140 through the network 130 and requests the establishment of a conference room for creating a co-mind map for a specific conference topic (S302). ). The establishment terminal 110 requests the establishment of the meeting room according to the operation of the establisher, and at the same time, the basic mind map generated and stored in step S300 and the meeting room setting information according to the establishment of the establisher (authority setting for each creator terminal, participant information, meeting room) Name, meeting topic, meeting room participation password, meeting time, meeting start time, object-specific setting information for each author, setting information for each author such as color / typeface, whether to display the author ID, etc.) are transmitted to the mind map server 140. In this case, as described above, the mind map server 140 according to the present invention refers to the participant information (e-mail address, mobile communication terminal identification number) included in the conference room setting information through the e-mail or SMS message to the participant. Meeting information including (participant information, meeting room name, meeting topic, meeting room join password, meeting time, meeting start time). The mind map server 140 that receives the basic mind map and meeting room setting information together with the meeting room establishment request opens a conference room for creating a joint mind map, and waits for the participation request of the participant terminal 120 to be received (S304). ).

Meanwhile, when the participant terminal 120 accesses the mind map server 140 and transmits a meeting room participation request according to the manipulation of the participant who has obtained the meeting information (S306), the mind map server 140 receives the participant terminal 120. Participant authentication is performed using the participant information (participant ID, the name of the conference room to which you want to participate, the password of the conference room, etc. if necessary) (S308), and if the authentication is successful, the corresponding stored in the mind map database 142. The basic mind map of the conference room is extracted and transmitted to the participant terminal 120 requesting participation (S310). At the same time, the participant information requested to participate in the conference room is transmitted to the establisher terminal 110 and the other participant terminal 120 participating in the conference room (S312).

When a preset conference start time arrives or a manager terminal set to a manager level (in FIG. 3, a manager level capable of declaring a conference start is given to a founder terminal, a meeting is started by a conference start declaration of a manager terminal). If the meeting re-order request is transmitted from the (S314), the mind map server 140, the participants start the meeting information for the co-minded map creator establishment unit 110 and all participants terminal 120 participating in the meeting room Start the process of creating a joint mind map by transmitting to (S316).

4 is a flowchart illustrating a process of delivering map configuration information of a joint mind map preparation system according to an exemplary embodiment of the present invention. Hereinafter, with reference to Figure 4 will be described in detail the delivery process of the map configuration information delivery process, that is, map configuration information during the creation of the co-mind map according to the present invention.

During an online meeting through the network 130 for creating a co-minded map, a co-minded map (shared map) is created on a specific creator's terminal 100 (the sender's creator's terminal) according to the operation of a specific creator among the creators participating in the conference room. If it is edited (S400), the sender creator terminal 100 generates the co-minded map creation / editing data according to the creator's input as map configuration information and transmits it to the mindmap server 140 (S402 and S404).

The mind map server 140 which has received the map configuration information transmitted from the sender creator terminal 100 analyzes / reflects the received map configuration information and updates the co-mind map stored in the mind map database 142 (S406). (S408), and transmits the received map configuration information to another creator terminal 100 (receiver side creator terminal) participating in the conference room (S410).

The receiver side creator terminal 100 receives the map configuration information transmitted from the mind map server 140, and interprets / reflects the received map configuration information to update the co-mind map displayed on the receiver side terminal 100. (S412, S414).

5 is a flowchart illustrating a synchronous recovery process of a joint mind map preparation system according to an exemplary embodiment of the present invention. Hereinafter, the process of determining the synchronization of each creator terminal according to the present invention and recovering the synchronization when the synchronization is lost will be described in detail with reference to FIG. 5. In the flowchart shown in FIG. 5, the author terminal 1 is a creator terminal whose synchronization is maintained with normal joint mind map data, and the author terminal 2 is a creator terminal whose synchronization is abnormal with abnormal joint mind map data.

First, the mind map server 140 determines whether a predetermined synchronization determination cycle has arrived (S500), and when the synchronization determination cycle arrives, requesting the CRC value to all creator terminals 100 participating in the conference room, and Based on the common mind map data stored in the map database 142, a reference CRC value, which is a criterion for determining synchronization, is generated (S502). At this time, when the present invention is configured in a manner that does not store the co-mind map data in the mind map database 142, a separate reference CRC value is not generated, out of the CRC values transmitted from each creator terminal 100 The CRC value transmitted from the majority or more creator terminals 100 may be set as the reference CRC value. In this case, since the integrity of the joint mind map data stored in the mind map database 142 may not be 100% certain, the reference CRC generated based on the joint mind map data stored in the mind map database 142 may be used. If the value is different from the CRC value transmitted from the creator terminal 100 of the majority or more, it is determined whether the synchronization is maintained based on the CRC value transmitted from the creator terminal 100 of the majority or more, and the common mind stored in the mind map database 142. The map data itself may also be configured to update using normal co-mind map data transmitted from the creator terminal 100 that transmitted the normal CRC value.

Each creator terminal 100 that receives a CRC value from the mind map server 140 generates a predetermined level of CRC value from the currently stored co-mind map data, and then generates the generated CRC value in the mind map server 140. S504 and S506.

The mind map server 140 receives a CRC value transmitted from each creator terminal 100 and generates a reference CRC based on the received CRC value of each creator terminal and the common mind map data stored in the mind map database 142. By comparing the values, CRC value validation is performed to determine whether the creator terminal 100 that transmits the abnormal CRC value exists (S508, S510).

If there is no author terminal 100 that transmits an abnormal CRC value, the mind map server 140 determines that the synchronization of the present system is maintained, and returns to step S500, and the creator terminal transmitting an abnormal CRC value ( If there is 100, the mind map server 140 determines that the synchronization of the corresponding creator terminal 100 is lost and performs the process of restoring the synchronization.

As described above, there are two main methods for the mind map server 140 to recover the synchronization of the creator terminal 100 that has transmitted an abnormal CRC value. 5 is a flowchart illustrating a process of restoring the synchronization of the corresponding creator terminal 100 using a method of prohibiting editing of the co-mind map of the creator terminal 100 that has transmitted an abnormal CRC value among two methods. .

When an abnormal CRC value is transmitted from the creator terminal 2, the mind map server 140 prohibits the creation / editing of the joint mind map of the creator terminal 2 (S512), and creates / edits the joint mind map transmitted from the mind map server 140. Upon receiving the prohibition command, the creator terminal 2 outputs a guide message ("synchronization of the mindset data is being updated due to lack of synchronization") through the display unit and prohibits the creation / editing of the mindset of the creator 2 at step S514.

At the same time, the mind map server 140 requests and receives normal common mind map data from the creator terminal 1 that has transmitted the normal CRC value (S516 and S518), and transmits the received joint mind map data to the creator terminal 2 (S520). . At this time, since the creation / editing of the joint mind map is prohibited, only the creator terminal 2 that transmits the abnormal CRC value is allowed to create / edit the joint mind map of the creator terminal which transmitted the remaining normal CRC value. Therefore, even during the synchronization recovery process of the creator terminal 2, the map configuration information constituting the joint mind map is generated through other creator terminals except the creator terminal 2 and reflected in the joint mind map. However, since the new map configuration information cannot be reflected while restoring the synchronization of the creator terminal 2, the mind map server 140 is generated in another creator terminal until the creator terminal 2 completes the download of normal co-mind map data. The map configuration information relayed through is temporarily stored in the mind map server 140 in time series.

The mind map server 140 determines whether the transmission of the normal co-mind map data to the creator terminal 2 is completed (S522), and when the creator terminal 2 downloads all the normal co-mind map data to complete the update of the co-mind map, The mind map server 140 generates map configuration information temporarily generated during the joint mind map creation / edit prohibition time of the creator terminal 2 and temporarily stored in time series in the mind map server 140 to the creator terminal 2 (S524). . The creator terminal 2 receives the normal common mind map data and the temporarily stored map configuration information and updates it with the latest common mind map (S526). When the common mind map update of the creator terminal 2 is completed, the mind map server 140 creates the creator terminal 2. By allowing the creation / editing of the co-mind map, the synchronization recovery process of the creator terminal 2 is terminated (S528).

Although not shown in FIG. 5, when the mind map server 140 prohibits the co-mind map creation / editing of all the author terminals 100 in order to restore synchronization, the normal co-mind map data of the author terminal 2 is used. When the download and the co-mind map update is completed and the synchronization is restored, the mind map server 140 allows the co-mind map creation / editing of all the author terminals 100 to terminate the sync recovery process of the author terminal 2.

FIG. 6 is a flowchart illustrating a consistency distribution process of a joint mind map preparation system according to an exemplary embodiment of the present invention. Hereinafter, with reference to Figure 6 will be described in detail with respect to the consistent dispersion process according to the present invention.

First, when a specific object already existing on the co-mind map is selected according to the author's manipulation in the creator terminal 1 (S600), the creator terminal 100 determines whether to allow editing of the selected specific object. If the specific object selected by the author 1 is an object of a level that cannot be edited with the level (administrator or general level) set to the author 1, or is an object that is already selected and locked by another author's terminal, the author's terminal 1 Prints an error message and prohibits editing.

On the other hand, when a specific object on the co-minded map selected by the author 1 is allowed to be edited to a level set to the author 1, and is not selected by another author terminal, the creator terminal 1 is allowed to select / edit the object. The creator 1 generates lock information on the specific object selected by the creator 1 and transmits the lock information to the mind map server 140 (S602 and S604).

The mind map server 140 receives the lock information transmitted from the creator terminal 1 and transmits the lock information received to another creator terminal (only the creator terminal 2 is shown in FIG. 6 for convenience) (S606), and the creator terminal 2 is a mind. The lock information received from the map server 140 may be received to store lock information that prohibits editing of the specific object selected by the creator terminal 1.

On the other hand, if the author 2 manipulates the creator terminal 2 and selects an object on the joint mind map (S608), the creator terminal 2 refers to the stored lock information and determines whether the object selected by the creator 2 is a locked object which is prohibited from editing or edited. It is determined whether the object is allowed (S610).

If the object selected by the author 2 is an object that is locked by the selection of the author 1 in step S600, the creator terminal 2 outputs an error message and disallows editing (S616). If author 1 is not selected and the object is not edited and is not locked, author terminal 2 permits author 2 to edit the object and creates lock information for the object according to author 2's selection. The mind map server 140 transmits to all other creator terminals participating in the conference room (S612 and S614).

During the above-described process, when the author 1 operates the creator terminal 1 to complete or deselect the editing of the specific object selected in step S600 (S618), the creator terminal 1 receives the release information for the specific object. It generates and transmits to all other creator terminals participating in the conference room through the mind map server 140 (S620, S622, S624).

The creator terminal 2 receives and stores release information about a specific object transmitted from the mind map server 140, and maintains consistency by allowing editing of the specific object prohibited from editing through step S606 (S626).

7 to 13 are exemplary views illustrating a screen displayed on a creator terminal in which a joint mind map is created by using a joint mind map preparation system according to an exemplary embodiment of the present invention. Hereinafter, a process of creating a co-mind map by manipulating an actual creator terminal according to the present invention will be described in detail with reference to FIGS. 7 to 13.

FIG. 7 is a diagram illustrating a state in which seven creators (A, B, C, D, E, F, G) participated in a conference room and started to create a joint mind map under the theme of 'autumn workshop'. The joint mind map itself shown in FIG. 7 is a basic mind map state uploaded by the establisher to the mind map server 140 for the opening of a conference room, and the basic mind map shown in FIG. 7 is the first level of the content of 'autumn workshop'. The central object (or central branch, hereinafter 'object' and 'branch' are used in the same sense) and 'level', 'time', 'play', 'object', ' 3 levels of 'Pocheon fishing ground' branched from the 2nd level object called 'Schedule', 'preparation' and 'other', and 2 levels of 'winter', ' It can be seen that it consists of three levels of 'ski' and 'fishing' objects branched from the second level object called 'play'.

Six meeting participants (or attendees), except the establisher, access the co-mind map server 140 by operating the participant terminal 120, and then request a participation in the conference room established by the establisher, as described above. The mind map is sent to begin the process of creating a joint mind map. In FIG. 7, the creator A selects the 'place' object, the creator B selects the 'time' object, the creator C selects the 'play' object, the creator D selects the 'play' object, and the creator e selects the 'place' object. Select F, the author selects the 'place' object, and the G author selects the 'place' object. As shown in FIG. 7, it can be seen that the outline of the object is displayed as a highlight of a rectangle as an indication that a specific object selected by each creator is selected.

Meanwhile, in FIG. 8, the author E selects and edits the central object 'autumn workshop', and the creator B inputs a sub-object called 'autumn' while the 'time' object is selected, and the author F writes 'schedule'. This is a diagram illustrating a state in which a sub-object called '1 night and 2 days' is input while an object is selected. On the other hand, if the author other than the user to edit a specific object on the co-mind map by operating the other author terminal 100, on the co-mind map displayed through the display unit of the author terminal 100 of the 'fall of FIG. The object is marked with a red rectangle (like a workshop) (as a visual effect that can be visually judged by the composition of the invention), allowing the author to edit the object by selecting it by another author. You will notice that you are busy. On the other hand, the contents of the object of the 'autumn workshop' of Figure 8 will be confirmed as edited to the 'winter workshop' by the author E as shown in the drawings after FIG.

In the top view of FIG. 9, after a few additional sub-object inputs are made in the state shown in FIG. 8, the A creator selects the 'place' object, the B author selects the 'target' object, and the C author selects the 'time'. 'Select object', 'D' select 'play' object, 'E' select 'topic' object, 'F' select 'preparation' object, 'G' select 'schedule' object. As described above, the object selected by the creator is represented by the highlight of the rectangle of the object's outer shell. The creator may manipulate the creator terminal 100 to select a specific object, edit the content, font, color, etc. of the selected specific object, or input a sub-object branched from the selected specific object. Editing of a specific object or inputting a sub-object may be performed by inputting an input signal (for example, double-clicking an object in case of editing an object, inputting a space bar while selecting an object, etc.).

In the lower drawing of FIG. 9, the F creator is preparing to input a sub-object by selecting a 'preparation' object and then pressing the spacebar (the 'preparation' object is displayed as a highlighted rectangle, and the sub-object into which the sub-object will be input. Is created), the C author is a drawing of the 'basketball' object selected.

FIG. 10 is an exemplary diagram in which a co-mind map is expanded in a short time by inputting content of multiple attendees simultaneously constructing a co-mind map in a state where the co-mind map creation process continues in the state of the bottom view of FIG. 9. As a number of authors participate in the joint mind map creation and input various ideas in real time, it can be seen that the effect of generating ideas quickly and diversely on the meeting topic can be seen.

11 is an exemplary diagram illustrating a state in which attributes of contents input to a specific object on a co-mind map are changed. As shown in FIG. 11, it can be seen that the text color of the object having the content of 'the other person is suddenly floating after being invisible' is changed at the third level branched from the 'play' object. As described above, in the joint mind map preparation system according to the present invention, the font, type, and color of the letters constituting the content of the object can be set as desired by the creator. Of course, such object content setting permission may be configured to be allowed or disallowed according to the conference room setting information or the operation of the administrator.

12 is an exemplary view illustrating a state in which a specific object on the common mind map is selected and edited. As described above, when another author selects and edits an object, the object being edited by the other author may be colored and displayed with a red rectangle on the co-mind map according to the present invention. In FIG. 12, as the creator B selects and edits an object called 'end of December-year-end party' at the third level, the corresponding object is displayed with red rectangles, and the creator G selects and edits another object of the fourth level. As a result, the object is shown in red color.

FIG. 13 is an exemplary view of a state in which a co-minded map with the theme of 'winter workshop' is completed through the co-minded map preparation system according to the present invention. As shown in FIG. 13, the co-minded map preparation system according to the present invention is shown. In this case, it can be seen that through online collaboration, many authors can participate in the meeting room to construct a collaborative mind map by arranging various ideas about one meeting topic in a structured and intuitive manner.
