Description

Information processing device, information processing program, and information processing method

[0001] The present disclosure relates to an information processing device, an information processing program, and an information processing method.

[0002] Japanese Patent Application Laid-Open No. 2018-045355 discloses a technology for displaying notes registered by a user on a screen displaying a drawing of a construction site.

[0003] However, if all users could freely register the above-mentioned notes or freely view all registered notes, problems could arise. For example, the number of notes displayed on the screen could become too large, making the display content cumbersome, or it could be impossible to register notes that only specific users should be aware of. The technology described in JP 2018-045355 A does not disclose that the registration and display of the above-mentioned notes can be managed for each user, and there is room for improvement.

[0004] Therefore, an object of the present disclosure is to provide an information processing device, an information processing program, and an information processing method that can accept only instructions related to annotations for drawing data that correspond to the authority set for each user.

[0005] The information processing device of the first aspect includes a management unit that manages whether or not annotations for each user on the drawing data can be created, edited, and viewed based on the authority set for each user who can access the digitized drawing data of a specified drawing, and a reception unit that receives instructions related to the annotations permitted by the management unit.

[0006] In the information processing device of the first aspect, the management unit manages whether or not each user is permitted to create, edit, and view annotations for the drawing data based on the authority set for each user who can access the drawing data. The reception unit then receives instructions related to the annotations permitted by the management unit. As a result, the information processing device can only receive instructions related to annotations for the drawing data that correspond to the authority set for each user.

[0007] An information processing device of a second aspect is an information processing device of the first aspect, in which the management unit allows a user who has been set with creation authority as the authority to create the annotation and edit the annotation in accordance with the creation authority.

[0008] In the information processing device of the second aspect, the management unit allows a user who has been granted creation authority to create an annotation and edit the annotation according to the creation authority, thereby allowing only the user who has been granted creation authority to create and edit the annotation.

[0009] An information processing device of a third aspect is an information processing device of the second aspect, and is provided with an input unit that enables the creation and editing of annotations for the drawing data by at least one of keyboard operation and touch operation on a display unit on which the drawing data is displayed.

[0010] In the information processing device of the third aspect, annotations for drawing data can be created and edited by at least one of keyboard operation and touch operation using the input unit, thereby improving the user convenience regarding operations related to creating and editing annotations.

[0011] An information processing device of a fourth aspect is an information processing device of any one of the first to third aspects, wherein the management unit allows a user to whom viewing authority has been set as the authority to view a specified annotation in accordance with the viewing authority, and includes a control unit that obtains annotation data for the specified annotation from a first table in which annotation data including the position on the drawing data where the operation related to creating the annotation was performed and the content of the annotation is stored in association with the drawing data, and displays the content of the specified annotation in an arrangement corresponding to the position on the drawing data where the operation related to creating the specified annotation was performed.

[0012] In a fourth aspect of the information processing device, the management unit allows a user who has been granted viewing authority to view a predetermined annotation according to the viewing authority. The control unit then retrieves the annotation data for the predetermined annotation from a first table in which the annotation data is stored in association with the drawing data, and displays the content of the predetermined annotation in an arrangement corresponding to the position on the drawing data where the operation related to creating the predetermined annotation was performed. This allows the information processing device to limit viewing of annotations to users who have been granted viewing authority. Furthermore, the information processing device displays the content of the predetermined annotation in an arrangement corresponding to the position on the drawing data where the operation related to creating the predetermined annotation was performed, making it easier for the user to understand the content of the annotation.

[0013] The information processing device of the fifth aspect is the information processing device of the fourth aspect, wherein when predetermined caution points are included in the drawing data as a result of analyzing the characters, figures, and symbols shown in the drawing data, the control unit obtains predetermined caution content corresponding to the predetermined caution points based on the analysis results from a second table in which caution content corresponding to each predetermined caution point is stored, and displays the predetermined caution content within a predetermined range from the predetermined caution point on the drawing data.

[0014] In the information processing device of the fifth aspect, when a predetermined caution point is included in the drawing data as a result of analyzing the characters, figures, and symbols shown in the drawing data, the control unit retrieves a predetermined caution content corresponding to the predetermined caution point based on the analysis result from a second table in which caution content corresponding to each predetermined caution point is stored, and displays the predetermined caution content within a predetermined range from the predetermined caution point on the drawing data. In this way, the information processing device allows the user to understand the caution content corresponding to the caution point included in the drawing data.

[0015] An information processing device of a sixth aspect is the information processing device of the fifth aspect, wherein the control unit displays the specified warning content in the margin when it is determined that a margin of a predetermined range or more is within the predetermined range.

[0016] In the information processing device of the sixth aspect, when it is determined that the margin is equal to or greater than the predetermined range, the control unit displays the predetermined warning content in the margin. This makes it possible to improve the visibility of the predetermined warning content compared to when the predetermined warning content is superimposed on characters, figures, symbols, etc. shown in the drawing data.

[0017] An information processing device of a seventh aspect is an information processing device of the sixth aspect, in which, if the specified warning content does not fit within the margin, the control unit adjusts the display mode of the specified warning content so that it fits within the margin.

[0018] In the information processing device of the seventh aspect, if the predetermined warning content does not fit within the margin, the control unit adjusts the display mode of the predetermined warning content so that it fits within the margin. As a result, according to the information processing device, the predetermined warning content can be displayed within the margin even if the amount of information of the predetermined warning content is large.

[0019] An information processing device of an eighth aspect is the information processing device of any one of the fifth to seventh aspects, wherein the management unit prohibits operations relating to editing of the caution content displayed on the drawing data.

[0020] In the information processing device of the eighth aspect, the management unit prohibits operations related to editing the caution content displayed on the drawing data, thereby preventing the caution content corresponding to the caution point from being altered from the content stored in the second table and communicated to the user.

[0021] The information processing program of the ninth aspect causes a computer to execute a process that manages whether or not annotations for each user on the drawing data are able to be created, edited, and viewed based on the authority set for each user who can access the digitized drawing data of a specified drawing, and accepts instructions related to the permitted annotations.

[0022] In a ninth aspect of the information processing program, a computer executes a process for managing whether or not annotations for each user of the drawing data are permitted to be created, edited, and viewed based on the authority set for each user who can access the drawing data. The information processing program also executes a process for accepting instructions related to the permitted annotations. This allows the information processing program to accept only instructions related to annotations for the drawing data that correspond to the authority set for each user.

[0023] In a tenth aspect of the information processing method, a computer executes a process to manage whether or not annotations for each user on the drawing data in which a specified drawing has been digitized are allowed to be created, edited, and viewed based on the authority set for each user who can access the digitized drawing data, and to accept instructions related to the permitted annotations.

[0024] In a tenth aspect of the information processing method, a computer executes a process for managing whether or not each user is permitted to create, edit, and view annotations for the drawing data, based on an authority set for each user who can access the drawing data. The information processing method also executes a process for accepting instructions related to the permitted annotations. This allows the information processing method to accept only instructions related to annotations for the drawing data that correspond to the authority set for each user.

[0025] As described above, according to the information processing device, information processing program, and information processing method disclosed herein, it is possible to accept only instructions related to annotations on drawing data according to the authority set for each user.

[0027] An information processing system 10 according to this embodiment will be described below. FIG. 1 is a diagram showing an example of a schematic configuration of the information processing system 10.

[0028] As shown in FIG. 1 , the information processing system 10 includes a user terminal 20 and a server 40. The user terminal 20 and the server 40 are connected via a network N. The network N may be, for example, the Internet, a local area network (LAN), or a wide area network (WAN). Note that although FIG. 1 illustrates three user terminals 20A, 20B, and 20C as the user terminals 20, the number of user terminals 20 included in the information processing system 10 is not particularly limited. In the following description, the term "user terminal 20" will be used collectively unless a specific user terminal is being referred to.

[0029] The user terminal 20 is a terminal owned by each user who uses the information processing system 10. The user terminal 20 is an example of an “information processing device” and a “computer” in the present disclosure. The server 40 stores various data used in the information processing system 10.

[0030] 2 is a block diagram showing the hardware configuration of the user terminal 20 and the server 40. As an example, the user terminal 20 is a "PC (Personal Computer)" and the server 40 is a "server computer." Note that since the user terminal 20 and the server 40 basically have a general computer configuration, the user terminal 20 will be described as a representative.

[0031] 2, the user terminal 20 includes a CPU (Central Processing Unit) 21, a ROM (Read Only Memory) 22, a RAM (Random Access Memory) 23, a storage 24, an input unit 25, a display unit 26, and a communication unit 27. Each component is connected to each other via a bus 28 so as to be able to communicate with each other.

[0032] The CPU 21 is a central processing unit that executes various programs and controls each part. That is, the CPU 21 reads programs from the ROM 22 or the storage 24 and executes the programs using the RAM 23 as a work area. The CPU 21 controls each of the above components and performs various arithmetic processing in accordance with the programs stored in the ROM 22 or the storage 24.

[0033] The ROM 22 stores various programs and various data. The RAM 23 serves as a working area for temporarily storing programs or data.

[0034] The storage 24 is configured by a storage device such as a hard disk drive (HDD), a solid state drive (SSD), or a flash memory, and stores various programs and various data.

[0035] The input unit 25 includes, for example, a mouse, a keyboard, a microphone, a camera, etc., and is used to perform various inputs.

[0036] The display unit 26 is, for example, a liquid crystal display, and displays various information. The display unit 26 employs a touch panel system, and also functions as the input unit 25. The input unit 25 and the display unit 26 are an example of the "input unit" in the present disclosure. The display unit 26 is also an example of the "display unit" in the present disclosure.

[0037] The communication unit 27 is an interface for communicating with other devices. For this communication, for example, a wired communication standard such as Ethernet (registered trademark) or FDDI, or a wireless communication standard such as 4G, 5G, or Wi-Fi (registered trademark) is used.

[0038] The functions of the CPU 41, ROM 42, RAM 43, storage 44, input unit 45, display unit 46, communication unit 47, and bus 48 of the server 40 are similar to the functions of the CPU 21, ROM 22, RAM 23, storage 24, input unit 25, display unit 26, communication unit 27, and bus 28 of the user terminal 20 described above.

[0039] Fig. 3 is a block diagram showing the configuration of the storage 24 of the user terminal 20. As shown in Fig. 3, the storage 24 stores an information processing program 24A for causing the CPU 21 to execute various processes described below. When executing the information processing program 24A, the user terminal 20 uses the hardware resources shown in Fig. 2 to execute processing based on the information processing program 24A. The information processing program 24A is an example of an "information processing program" in the present disclosure.

[0040] Fig. 4 is a block diagram showing the configuration of the storage 44 of the server 40. As shown in Fig. 4, the storage 44 stores a drawing database 44A, an annotation database 44B, and an authority database 44C.

[0041] The drawing database 44A stores a plurality of drawing data, which are electronic versions of a plurality of drawings. The drawing data is, for example, data in Portable Document Format (PDF) format generated by scanning paper drawings showing mechanical parts. Each of the plurality of drawing data stored in the drawing database 44A is associated with a drawing number as information for identifying the drawing data.

[0042] The annotation database 44B stores an annotation table in which annotation data including the contents of annotations created by users who have been granted creation authority (described later) is linked to drawing data and stored, and a caution table in which caution contents corresponding to each predetermined caution are stored. Details of the annotation table and the caution table will be described later. The annotation table is an example of a "first table" in the present disclosure, and the caution table is an example of a "second table" in the present disclosure.

[0043] Annotations according to this embodiment are visible information such as characters, figures, symbols, and images added to drawing data. The content of the created annotation is displayed on the drawing data in a form that can be visually perceived by the user (for example, characters, figures, symbols, and images).

[0044] Furthermore, the points of caution according to this embodiment are predetermined points of caution in the procurement, processing, or inspection of machine parts, which are indicated in the drawing data. In the following, as an example, the predetermined points of caution will be described as "qualitative expressions indicated in the drawing data." "Qualitative expressions" are expressions that are not indicated by numerical values, such as "no scratches" or "no water leaks."

[0045] Furthermore, the caution content according to this embodiment is a specific representation of the qualitative expression of the corresponding caution point. For example, if the corresponding caution point is "Do not...", the caution content indicates specific details that can achieve "Do not...".

[0046] The authority database 44C stores a user information table in which user information about each user who can access the drawing data is stored, and an authority table in which authority set for each user is stored.

[0047] As an example, a user who can access drawing data is a user who has registered for a predetermined application (hereinafter referred to as a "predetermined application") related to viewing drawing data. When registering for a predetermined application, the user inputs user information such as a login ID (identification), a login PW (password), a user name, and a department to which the user belongs in an organization (e.g., a company). The input user information is associated with each user and stored in a user information table.

[0048] In this embodiment, the above-mentioned rights include a creation right and a viewing right.

[0049] The creation authority is authority to create a new annotation and to edit an annotation, including updating and deleting the content of an annotation that has already been created.

[0050] The viewing authority is the authority to view annotations. Here, the viewing authority allows the range of annotations that can be viewed to be set in detail according to the user or department, etc. The viewing range can be set appropriately, for example, to all annotations, only annotations by a specific user, or only annotations by a specific department.

[0051] As an example, in this embodiment, an administrative user who manages the above-mentioned permissions sets, for each user registered in a specified application, no permissions, only creation permissions, only viewing permissions, or both creation permissions and viewing permissions, and enters the contents into the permissions table.

[0052] FIG. 5 is an explanatory diagram showing the contents of the authority table stored in the authority database 44C.

[0053] 5 has column names such as authority ID, user name, department, person, and department, etc. Note that the column names of the authority table are not limited to those shown above.

[0054] An authority ID is registered in each field of the column named "authority ID." The authority IDs are assigned consecutive numbers in the order of registration in the authority table, such as "0001," "0002," "...," etc.

[0055] In each field of the column named "User Name," the name of each user who has registered in a predetermined application is registered. For example, in the field of the column named "User Name" corresponding to "Authority ID: 0001," the username "User A" is registered.

[0056] In each field of the column named "Department", the department to which each user who has registered in the predetermined application belongs is registered. For example, in the field of the column named "Department" corresponding to "Authority ID: 0001", the department to which the user belongs, "Design", is registered.

[0057] In each field of the column named "User", the authority of each individual user who has registered in the predetermined application is registered. As described above, the authority includes creation authority and viewing authority, and the authority table registers the presence or absence of each type of authority: "creation", "viewing", "update", and "deletion". In the authority table, "◯" indicates that the authority is present, and "-" indicates that the authority is not present.

[0058] In each field of the column named "By Department," the authority for each department of each user registered in the predetermined application is registered. As an example, the authority table registers whether each user has the authority to "view," "update," and "delete" for each of the departments of "design," "procurement," "manufacturing," and "quality assurance."

[0059] According to the contents of the authority table shown in Figure 5, User A, who belongs to the design department, can create annotations and view, update, and delete his / her own annotations. User A can also view, update, and delete annotations from all departments.

[0060] User B, who belongs to the design department, can create annotations and view, update, and delete his own annotations. User B can view and update, but not delete, annotations from the design department. User B can only view annotations from other departments (procurement, manufacturing, and quality assurance).

[0061] Furthermore, user C who belongs to the design department cannot create, update, or delete annotations, but can view annotations from all departments.

[0062] User D, who belongs to the manufacturing department, can create annotations and view, update, and delete his / her own annotations. User D can also view, update, and delete annotations for his / her own department. Furthermore, User D can only view annotations for the design department and quality assurance department, but cannot view, update, or delete annotations for the procurement department.

[0063] User E, who belongs to the Procurement department, can create annotations and view, update, and delete his / her own annotations. User E can also view, update, and delete annotations for his / her own department. Furthermore, User E can only view annotations for other departments (design, manufacturing, and quality assurance).

[0064] Next, a description will be given of the functional configuration of the user terminal 20. Fig. 6 is a block diagram showing an example of the functional configuration of the user terminal 20.

[0065] 6, the CPU 21 of the user terminal 20 has, as functional components, an acquisition unit 21A, a management unit 21B, a reception unit 21C, a control unit 21D, and an analysis unit 21E. Each functional component is realized by the CPU 21 reading and executing an information processing program 24A stored in the storage 24. The acquisition unit 21A acquires various types of information from the server 40.

[0066] The management unit 21B manages whether or not annotations for each user of the drawing data are allowed to be created, edited, and viewed based on the authority set for each user who can access the drawing data. Specifically, the management unit 21B allows users who have been set with creation authority to create annotations and edit the annotations according to the creation authority. Editing annotations according to the creation authority means, for example, that if the creation authority is set to only update annotations, only annotations can be updated; if the creation authority is set to only delete annotations, only annotations can be deleted; and if the creation authority is set to both update and delete annotations, both annotations can be updated and deleted. Furthermore, the management unit 21B allows users who have been set with viewing authority to view specific annotations according to the viewing authority. The specific annotations according to the viewing authority refer to, for example, annotations for departments registered with "O" in the authority table shown in FIG. 5.

[0067] The receiving unit 21C receives instructions related to annotations permitted by the management unit 21B for the drawing data acquired by the acquisition unit 21A. The instructions related to annotations include instructions related to creating annotations, instructions related to editing annotations, and instructions related to viewing annotations.

[0068] For example, when a user who has been granted creation authority performs an operation related to creating an annotation (hereinafter referred to as a "creation operation"), the accepting unit 21C accepts an instruction related to creating an annotation. In this case, the user can create an annotation on the user terminal 20 of the user, and the user can create an annotation by operating a keyboard as the input unit 25, for example.

[0069] On the other hand, if a user who does not have the creation authority performs a creation operation, the accepting unit 21C does not accept an instruction to create an annotation. In this case, the user cannot create an annotation on the user terminal 20 of the user.

[0070] Furthermore, the position on the drawing data created by the user who has been granted creation authority and the content of the created annotation are linked to the drawing data as annotation data and stored in the annotation table. Here, the position on the drawing data is indicated by two-dimensional coordinate values ​​(X and Y coordinate values) with one of the corners of the drawing data as the origin.

[0071] The control unit 21D performs display control to display various information on the drawing data, including, for example, the contents of annotations stored in the annotation table and the contents of notes stored in the note table.

[0072] The analysis unit 21E performs known character recognition and image recognition processes on the drawing data to analyze the characters, figures, and symbols shown in the drawing data. How the analysis results by the analysis unit 21E are used will be described later.

[0073] 7 is a flowchart showing the flow of creating annotations for drawing data. The CPU 21 reads the information processing program 24A from the storage 24, loads it into the RAM 23, and executes it to perform the processing of the flowchart. As an example, the processing is performed when a user who can access the drawing data logs in to a predetermined application and specifies the drawing data.

[0074] 7, the CPU 21 acquires the drawing data, the drawing number of which has been specified by the user, from the drawing database 44A of the server 40, and displays the acquired drawing data on the display unit 26 of the user terminal 20 owned by the user. Then, the CPU 21 proceeds to step S11.

[0075] In step S11, the CPU 21 determines whether a creation operation has been performed on the drawing data. If the CPU 21 determines that a creation operation has been performed (step S11: YES), the process proceeds to step S12. On the other hand, if the CPU 21 determines that a creation operation has not been performed (step S11: NO), the process waits until a creation operation is performed. As an example, the creation operation is an operation of left-clicking an arbitrary position on the drawing data with a mouse as the input unit 25.

[0076] In step S12, the CPU 21 determines whether the user who performed the creation operation is a user for whom creation authority has been set. If the CPU 21 determines that the user is a user for whom creation authority has been set (step S12: YES), the CPU 21 proceeds to step S13. On the other hand, if the CPU 21 determines that the user is not a user for whom creation authority has been set (step S12: NO), the CPU 21 ends the process. The CPU 21 refers to the authority table in the authority database 44C, and determines whether to proceed to step S13 or end the process depending on whether creation authority has been set for the user who performed the creation operation.

[0077] In step S13, the CPU 21 accepts, for example, an annotation created by a user who has been granted creation authority using a keyboard as the input unit 25. The content of the annotation created by the user is displayed on the drawing data. Then, the CPU 21 proceeds to step S14.

[0078] In step S14, the CPU 21 determines whether the termination condition is met. If the CPU 21 determines that the termination condition is met (step S14: YES), the process proceeds to step S15. On the other hand, if the CPU 21 determines that the termination condition is not met (step S14: NO), the process returns to step S13. As an example, the CPU 21 determines that the termination condition is met when a termination operation is performed. The termination operation is, for example, left-clicking an end button (not shown) on the display unit 26 with a mouse serving as the input unit 25.

[0079] In step S15, the CPU 21 updates the annotation table based on the content of the created annotation, and then ends the process.

[0080] 8 is a flowchart showing the flow of editing annotations for drawing data. The CPU 21 reads the information processing program 24A from the storage 24, loads it into the RAM 23, and executes it to perform the processing of the flowchart. As an example, this processing is performed in parallel with the processing shown in FIG. 7.

[0081] 8, the CPU 21 acquires the drawing data, the drawing number of which is specified by a user who can access the drawing data, from the drawing database 44A of the server 40, and displays the acquired drawing data on the display unit 26 of the user terminal 20 owned by the user. Then, the CPU 21 proceeds to step S21.

[0082] In step S21, the CPU 21 determines whether an operation related to editing an annotation on the drawing data (hereinafter, "editing operation") has been performed. If the CPU 21 determines that an editing operation has been performed (step S21: YES), the process proceeds to step S22. On the other hand, if the CPU 21 determines that an editing operation has not been performed (step S21: NO), the process waits until an editing operation is performed. As an example, the editing operation is an operation of left-clicking on an annotation displayed on the drawing data with a mouse serving as the input unit 25.

[0083] In step S22, the CPU 21 determines whether the user who performed the editing operation is a user who has been granted creation authority to edit the annotation on which the editing operation was performed. If the CPU 21 determines that the user is a user who has been granted creation authority (step S22: YES), the CPU 21 proceeds to step S23. On the other hand, if the CPU 21 determines that the user is not a user who has been granted creation authority (step S22: NO), the CPU 21 terminates the process. The CPU 21 refers to the authority table in the authority database 44C, and determines whether to proceed to step S23 or terminate the process depending on whether the user who performed the editing operation is granted authority to at least one of update and delete the annotation.

[0084] In step S23, the CPU 21 accepts editing of the annotation according to the creation authority by a user who has been granted creation authority to edit the annotation, for example, using a keyboard as the input unit 25. The CPU 21 proceeds to step S24.

[0085] In step S24, the CPU 21 determines whether the termination condition is met. If the CPU 21 determines that the termination condition is met (step S24: YES), the CPU 21 proceeds to step S25. On the other hand, if the CPU 21 determines that the termination condition is not met (step S24: NO), the CPU 21 returns to step S23. As an example, the CPU 21 determines that the termination condition is met when the same termination operation as above is performed.

[0086] In step S25, the CPU 21 updates the annotation table based on the content of the edited annotation, and then ends the process.

[0087] Fig. 9 shows a first display example displayed on the display unit 26 of the user terminal 20. As an example, Fig. 9 shows drawing data on which no annotations have been created.

[0088] In the drawing data shown in FIG. 9, a part image 50, a part image 51, part information 52, and a title column 53 are displayed.

[0089] As shown in the part information 52, the part image 50 shows an image of a part with a part number of "1", a product name of "input shaft", and a material of "S45C".

[0090] As shown in the part information 52, the part image 51 shows an image of a part whose part number is "2", whose product name is "spur gear", and whose material is "S48C".

[0091] Various pieces of information related to the drawing data are written in the title column 53. For example, the title column 53 contains information 53A indicating the customer to whom the parts shown in the part images 50 and 51 are to be delivered, and information 53B indicating the drawing number corresponding to the drawing data.

[0092] 10 is a second display example displayed on the display unit 26 of the user terminal 20. As an example, FIG. 10 shows drawing data on which annotations have been created by executing the process shown in FIG.

[0093] In the drawing data shown in Fig. 10, annotation information 60 indicating the content of the annotation created in step S13 is added below the component image 50 in comparison with the drawing data shown in Fig. 9. The annotation information 60 shown in Fig. 10 indicates the content of the annotation created by user X, who has been granted creation authority. The content of the annotation is the text and symbols "tightening torque 30.0 to 34.5 Nm."

[0094] 11 is a third example of a display displayed on the display unit 26 of the user terminal 20. As an example, FIG. 11 shows drawing data in which annotations have been edited by executing the process shown in FIG.

[0095] In the drawing data shown in Fig. 11, the content of the annotation information 60 has been updated from the drawing data shown in Fig. 10. The annotation information 60 shown in Fig. 11 shows the content of the annotation updated by user X, who has been granted creation authority that enables him or her to update his or her own annotations. The content of the annotation is the text and symbols "tightening torque 32.0 to 35.5 Nm," and the tightening torque value has been updated.

[0096] Next, the contents of the annotation table will be described below: Fig. 12 is an explanatory diagram showing the contents of the annotation table stored in the annotation database 44B.

[0097] 12 has column names such as annotation ID, drawing number, coordinate value, annotation content, user name, department, date, character string, etc. Note that the column names of the annotation table are not limited to those shown above.

[0098] Annotation IDs are registered in each field of the column named "annotation ID." The annotation IDs are assigned consecutive numbers in the order of registration in the annotation table, such as "0001," "0002," "...," etc.

[0099] The drawing numbers of the drawing data are registered in each field of the column named "Drawing Number." In the flowcharts shown in Figures 7 and 8, the CPU 21 obtains the drawing numbers of the drawing data for which at least one of annotations has been created and edited from the drawing database 44A and registers them in the corresponding fields. For example, the drawing number "DR-0000" shown in information 53B of the title column 53 in Figures 9 to 11 is registered in the field named "Drawing Number" corresponding to "Annotation ID: 0001."

[0100] Each field in the column named "Coordinate Value" registers four X and Y coordinate values, including a position on the drawing data where a user with creation authority has performed a creation operation. The CPU 21 derives a rectangle whose upper left vertex is the X and Y coordinate values ​​indicating the position on the drawing data where the user has performed a creation operation. The CPU 21 then registers the X and Y coordinate values ​​indicating each of the four vertices of the rectangle in the corresponding fields. For example, the field named "Coordinate Value" corresponding to "Annotation ID: 0001" registers the following X and Y coordinate values: "X: 100, Y: 200" indicating the upper left vertex, "X: 100, Y: 180" indicating the lower left vertex, "X: 200, Y: 200" indicating the upper right vertex, and "X: 200, Y: 180" indicating the lower right vertex.

[0101] In each field of the column named "annotation content," the content of annotations created by users who have been granted creation authority or the content of annotations edited by those users is registered. For example, in steps S15 and S25, the CPU 21 executes known character recognition processing and image recognition processing to analyze the content of the annotation as text data. The CPU 21 then registers the analyzed text data in the corresponding field. For example, in the field named "annotation content" corresponding to "annotation ID: 0001," the annotation content "tightening torque 32.0 to 35.5 Nm" shown in the annotation information 60 in FIG. 11 is registered.

[0102] The name of the user who created the annotation is registered in each field of the column named "User Name." The CPU 21 identifies the user who created the annotation from the login history of the predetermined application, and obtains the username of the user from the user information table of the authority database 44C. The CPU 21 registers the obtained username in the corresponding field. For example, the username "User X" is registered in the field of the column named "User Name" corresponding to "Annotation ID: 0001."

[0103] In each field of the column named "Department", the department to which the user who created the annotation belongs is registered. The CPU 21 identifies the user who created the annotation from the login history of the predetermined application, and obtains the department to which the user belongs from the user information table of the authority database 44C. The CPU 21 registers the obtained department in the corresponding field. For example, in the field of the column named "Department" corresponding to "Annotation ID: 0001", the department "Manufacturing" is registered.

[0104] The date on which the annotation was created is registered in each field of the column named "Date." The CPU 21 obtains the date when the process of step S15 is performed and registers it in the corresponding field. For example, the date "2024 / 6 / 1" is registered in the field of the column named "Date" corresponding to "Annotation ID: 0001."

[0105] In each field of the column named "character string," whether the annotation created by the user to whom creation authority has been set is written horizontally or vertically is registered. For example, in step S15, the CPU 21 executes known character recognition processing and image recognition processing to analyze the direction of the character string indicating the annotation created by the user. Then, the CPU 21 registers the analyzed direction of the character string in the corresponding field. For example, in the field of the column named "character string" corresponding to "annotation ID: 0001," the character string direction "horizontal" is registered.

[0106] As described above, the information in each field of the annotation table shown in Fig. 12 is updated based on whether an annotation is created or edited. Although not shown, each time a new annotation is created, an annotation ID such as "0002" or "0003" is registered in a field in the column named "Annotation ID," and information is registered in each field of other columns named corresponding to "Annotation ID: 0002" or the like.

[0107] 13 is a flowchart showing the flow of displaying annotations on drawing data. The CPU 21 reads the information processing program 24A from the storage 24, loads it into the RAM 23, and executes it to perform the processing of the flowchart. As an example, this processing is performed in parallel with the processing shown in FIGS. 7 and 8.

[0108] 13, the CPU 21 acquires drawing data, the drawing number of which has been designated by a user who can access the drawing data, from the drawing database 44A of the server 40. Then, the CPU 21 proceeds to step S31.

[0109] In step S31, the CPU 21 refers to the authority table of the authority database 44C to determine the viewing authority of the user, and then the CPU 21 proceeds to step S32.

[0110] In step S32, the CPU 21 acquires annotation data of a predetermined annotation according to the viewing authority set for the user from the annotation table of the annotation database 44 B. Then, the CPU 21 proceeds to step S33.

[0111] In step S33, the CPU 21 displays the drawing data acquired in step S30 and the contents of the predetermined annotation indicated in the annotation data acquired in step S32 on the display unit 26 of the user terminal 20 owned by the user. Then, the CPU 21 proceeds to step S34.

[0112] In step S34, the CPU 21 determines whether the termination condition is met. If the CPU 21 determines that the termination condition is met (step S34: YES), the CPU 21 terminates the process. On the other hand, if the CPU 21 determines that the termination condition is not met (step S34: NO), the CPU 21 waits until the termination condition is met. As an example, the CPU 21 determines that the termination condition is met when the same termination operation as described above is performed.

[0113] Fig. 14 is a fourth display example displayed on the display unit 26 of the user terminal 20. As an example, Fig. 14 shows drawing data displayed on the display unit 26 of the user terminal 20 owned by user D (see Fig. 5) who belongs to the manufacturing department, by executing the process shown in Fig. 13.

[0114] In the drawing data shown in Figure 14, annotation information 80 and annotation information 81 indicating the contents of specific annotations that user D is permitted to view based on his or her viewing authority are displayed below part information 52 for the drawing data shown in Figure 9.

[0115] In this case, the CPU 21 acquires annotation data for predetermined annotations corresponding to annotation information 80 and annotation information 81 from the annotation table shown in FIG. 12 . Specifically, the CPU 21 acquires, as the annotation data, information registered in a field of a column having a column name of a coordinate value, annotation content, and character string. The CPU 21 then displays the acquired annotation content in the direction of the acquired character string within a rectangular area whose vertices are the acquired four X and Y coordinate values. As a result, in annotation information 80, the annotation content "Is it okay to use minor chamfering for R0.2?" is displayed horizontally at approximately the same position on the drawing data created by the user with creation authority. Similarly, in annotation information 81, the annotation content "Minor chamfering is OK" is displayed horizontally at approximately the same position on the drawing data created by the user.

[0116] Here, if the contents of the annotations shown in annotation information 80, annotation information 81, etc. do not fit within the rectangular area, the CPU 21 may perform one of the following processes: (1) Reduce the display size of the annotation contents while maintaining the rectangular area; (2) Insert a line break in the text shown in the annotation contents while maintaining the rectangular area; or (3) Expand the rectangular area while maintaining the display size of the annotation contents. However, the above processes are not necessarily required. In this case, for example, part of the annotation contents shown in annotation information 80, annotation information 81, etc. may be cut off, resulting in invisible text.

[0117] Fig. 15 is a fifth example of display displayed on the display unit 26 of the user terminal 20. As an example, Fig. 15 shows drawing data displayed on the display unit 26 of the user terminal 20 owned by user E (see Fig. 5) who belongs to the procurement department, by executing the process shown in Fig. 13.

[0118] 15, annotation information 80, annotation information 81, and annotation information 82 indicating the contents of predetermined annotations that user E is permitted to view in accordance with the viewing authority are displayed below the part information 52 and above the part image 51 in comparison with the drawing data shown in FIG. 9. Note that annotation information 80 and annotation information 81 are the same as those in FIG. 14, and therefore description thereof will be omitted.

[0119] In this case, the CPU 21 acquires annotation data of a predetermined annotation corresponding to the annotation information 82 from the annotation table shown in Fig. 12. Specifically, the CPU 21 acquires, as the annotation data, information registered in a field of a column to which a column name of a coordinate value, annotation content, and character string is assigned. The CPU 21 then displays the acquired annotation content in the direction of the acquired character string within a rectangular area whose vertices are the acquired four X and Y coordinate values. As a result, in the annotation information 82, the annotation content "2,500 yen from yyy company" is displayed horizontally in approximately the same position on the drawing data created by the user who has been granted creation authority.

[0120] As described above, even when an annotation is displayed on the same drawing data, the content of the annotation displayed on the drawing data will differ depending on the viewing authority set for the user viewing the drawing data.

[0121] 16 is a flowchart showing a flow of determining whether or not to display a warning content on drawing data. The CPU 21 reads the information processing program 24A from the storage 24, loads it into the RAM 23, and executes it, thereby performing the processing of the flowchart. As an example, this processing is performed before the processing shown in FIG. 7, the processing shown in FIG. 8, or the processing shown in FIG. 13, when a user who can access the drawing data logs in to a predetermined application and specifies the drawing data.

[0122] 16, the CPU 21 acquires the drawing data, the drawing number of which has been specified by the user, from the drawing database 44A of the server 40. Then, the CPU 21 proceeds to step S41.

[0123] In step S41, the CPU 21 analyzes the information indicated in the drawing data acquired in step S40. Specifically, the CPU 21 executes known character recognition processing and image recognition processing to analyze the characters, figures, and symbols indicated in the drawing data. The CPU 21 then proceeds to step S42.

[0124] In step S42, the CPU 21 determines whether or not predetermined attention points are included in the drawing data as a result of the analysis in step S41. Here, if the CPU 21 determines that attention points are included in the drawing data (step S42: YES), the process proceeds to step S44. On the other hand, if the CPU 21 determines that attention points are not included in the drawing data (step S42: NO), the process proceeds to step S43. The CPU 21 determines that attention points are included in the drawing data if the information indicated in the drawing data analyzed in step S41 is registered in the attention point table of the annotation database 44B. On the other hand, the CPU 21 determines that attention points are not included in the drawing data if the information indicated in the drawing data is not registered in the attention point table.

[0125] In step S43, the CPU 21 displays the drawing data acquired in step S40 on the display unit 26 of the user terminal 20 owned by the user. Then, the CPU 21 ends the process. That is, in this case, as shown in Fig. 14 or 15, the drawing data showing the content of the predetermined annotation according to the viewing authority is displayed on the display unit 26. Thereafter, depending on whether the user performs a creation operation or an editing operation, the process from step S11 shown in Fig. 7 or from step S21 shown in Fig. 8 is performed.

[0126] In step S44, the CPU 21 acquires, from the attention table, the predetermined attention content corresponding to the predetermined attention based on the analysis result in step S41, and then the CPU 21 proceeds to step S45.

[0127] In step S45, the CPU 21 determines whether there is a predetermined margin or more within a predetermined range from the predetermined attention point on the drawing data. The predetermined range is a rectangular area with an arbitrary position of the predetermined attention point on the drawing data as its center. The predetermined range is a rectangular area smaller in area than the predetermined range. A margin is an area on the drawing data that is left blank and does not contain information such as text, figures, or symbols. If the CPU 21 determines that there is a predetermined margin or more within the predetermined range from the predetermined attention point (step S45: YES), the CPU 21 proceeds to step S47. On the other hand, if the CPU 21 determines that there is no predetermined margin or more within the predetermined range from the predetermined attention point (step S45: NO), the CPU 21 proceeds to step S46.

[0128] In step S46, the CPU 21 displays the drawing data, acquired in step S44, indicating the predetermined caution content on the display unit 26 of the user terminal 20 owned by the user. At this time, the CPU 21 displays the predetermined caution content within a predetermined range from the predetermined caution point on the drawing data. The CPU 21 then terminates the process. Thereafter, depending on whether the user is performing a creation operation or an editing operation, the process proceeds to step S11 and subsequent steps shown in FIG. 7 or step S21 and subsequent steps shown in FIG. 8.

[0129] In step S47, the CPU 21 determines whether the predetermined notice content acquired in step S44 fits within the margin. If the CPU 21 determines that the predetermined notice content fits within the margin (step S47: YES), the process proceeds to step S49. On the other hand, if the CPU 21 determines that the predetermined notice content does not fit within the margin (step S47: NO), the process proceeds to step S48. As an example, the CPU 21 determines whether the predetermined notice content fits within the margin based on the result of comparing the initial setting display size of the predetermined notice content with the margin area.

[0130] In step S48, the CPU 21 adjusts the display mode of the predetermined warning content acquired in step S44 so that it fits within the margin. For example, the CPU 21 reduces the display size of the predetermined warning content so that it fits within the margin. The CPU 21 then proceeds to step S49.

[0131] In step S49, the CPU 21 displays the drawing data, acquired in step S44, indicating the predetermined caution content on the display unit 26 of the user terminal 20 owned by the user. At this time, the CPU 21 displays the predetermined caution content so that it fits within a predetermined margin from the predetermined caution point on the drawing data. The CPU 21 then terminates the process. Thereafter, depending on whether the user is performing a creation operation or an editing operation, the process proceeds to step S11 and subsequent steps shown in FIG. 7 or step S21 and subsequent steps shown in FIG. 8.

[0132] Next, the contents of the attention table will be described below: Fig. 17 is an explanatory diagram showing the contents of the attention table stored in the annotation database 44B.

[0133] 17 has column names such as attention content ID, attention point, customer, attention content, etc. Note that the column names of the attention point table are not limited to those shown above.

[0134] A warning content ID is registered in each field of the column named "warning content ID." The warning content IDs are assigned consecutive numbers in the order of registration in the warning point table, such as "0001," "0002," "...," etc.

[0135] Predetermined cautions are registered in each field of the column named "Cautions." For example, the caution "no scratches" is registered in the field named "Cautions" corresponding to "Caution Content ID: 0001."

[0136] In each field of the column named "Customer", the name of the customer who should deal with the caution is registered. For example, in the field of the column named "Customer" corresponding to "Caution Content ID: 0001", the customer name "Company Y" is registered.

[0137] In each field of the column named "Caution," a caution corresponding to the caution registered in the field named "Caution" in the same record is registered. For example, in the field named "Caution" corresponding to "Caution ID: 0001," the caution "Scratches that are not caught by fingernails are acceptable" is registered.

[0138] Here, various information is registered in the attention table periodically by a specific user. The specific user registers attention details corresponding to attention points for each customer in the attention table, taking into consideration the details of past transactions with each customer, etc. As described above, attention details corresponding to attention points may differ for each customer, so different attention details may be registered in the attention table for the same attention point for different customers.

[0139] 18 is an explanatory diagram showing an example of drawing data including predetermined attention points. As an example, FIG. 18 shows the drawing data acquired by the CPU 21 in step S40.

[0140] In the drawing data shown in FIG. 18, a part image 90, part information 91, and a title column 92 are displayed.

[0141] As shown in the part information 91, the part image 90 shows an image of a part with the part number "1", the product name "spur gear", and the material "S48C".

[0142] Various pieces of information related to the drawing data are written in the title column 92. For example, the title column 92 contains information 92A indicating the drawing number of the drawing shown in the drawing data, information 92B indicating the customer to whom the part shown in the part image 90 is to be delivered, and the like.

[0143] 18, instruction information 93 indicating the instructions written by the customer shown in information 92B is displayed below the component image 90. The instruction information 93 is the text "no scratches."

[0144] Fig. 19 shows a sixth display example displayed on the display unit 26 of the user terminal 20. As an example, Fig. 19 shows drawing data displayed on the display unit 26 in step S49.

[0145] In this case, the CPU 21 determines in step S42 that the drawing data includes a predetermined caution based on the text data obtained by analyzing the instruction information 93. The predetermined caution is the predetermined caution of "no scratches." Then, in step S43, the CPU 21 acquires the predetermined caution, "Scratches that cannot be picked up by fingernails are permitted," registered in the "Caution Content" field corresponding to the "Caution Content ID: 0001" in the caution table shown in FIG. 17, based on the text data obtained by analyzing the information 92B. Note that the drawing data includes a predetermined amount of white space within the predetermined range from the predetermined caution of "no scratches." As a result, in the display example shown in FIG. 19, text information 94 indicating the predetermined caution, "scratches that cannot be picked up by fingernails are permitted," is displayed below the instruction information 93.

[0146] Here, the CPU 21 prohibits operations related to editing the warning content displayed on the drawing data, i.e., the warning content (e.g., text information 94) displayed on the drawing data cannot be updated or deleted.

[0147] As described above, in the user terminal 20, the CPU 21, as a function of the management unit 21B, manages whether or not each user is permitted to create, edit, and view annotations for the drawing data based on the authority set for each user who can access the drawing data. The CPU 21 then, as a function of the reception unit 21C, receives instructions related to permitted annotations. This allows the user terminal 20 to receive only instructions related to annotations for the drawing data that correspond to the authority set for each user. It should be clear from the description of the above embodiment that in the information processing system 10, even if annotations are created for the drawing data, the drawing data itself is not changed.

[0148] Furthermore, in the user terminal 20, the CPU 21, as a function of the management unit 21B, allows users who have been granted creation authority to create annotations and edit annotations according to the creation authority. As a result, the user terminal 20 allows only users who have been granted creation authority to create and edit annotations.

[0149] Furthermore, in the user terminal 20, the CPU 21, as a function of the management unit 21B, allows users who have been granted viewing authority to view a predetermined annotation according to the viewing authority. Then, as a function of the control unit 21D, the CPU 21 retrieves annotation data for the predetermined annotation from an annotation table in which annotation data is stored in association with drawing data, and displays the content of the predetermined annotation in an arrangement corresponding to the position on the drawing data where the operation to create the predetermined annotation was performed. This allows the user terminal 20 to limit viewing of annotations to users who have been granted viewing authority. Furthermore, the user terminal 20 displays the content of the predetermined annotation in an arrangement corresponding to the position on the drawing data where the operation to create the predetermined annotation was performed, making it easier for the user to understand the content.

[0150] Furthermore, in the user terminal 20, the CPU 21, as a function of the analysis unit 21E, analyzes the characters, figures, and symbols shown in the drawing data. Then, as a function of the control unit 21D, the CPU 21, when it determines as a result of the analysis that predetermined cautions are included in the drawing data, retrieves predetermined caution content corresponding to the predetermined caution based on the analysis result from a caution table storing caution content corresponding to each predetermined caution, and displays the predetermined caution content within a predetermined range from the predetermined caution on the drawing data. In this way, the user terminal 20 allows the user to understand the caution content corresponding to the caution included in the drawing data.

[0151] Furthermore, in the user terminal 20, the CPU 21, as a function of the control unit 21D, displays a predetermined warning content in the margin when it is determined that the margin is equal to or greater than a predetermined range. This allows the user terminal 20 to improve the visibility of the predetermined warning content compared to when the predetermined warning content is displayed superimposed on characters, figures, symbols, etc. shown in the drawing data.

[0152] Furthermore, in the user terminal 20, the CPU 21, as a function of the control unit 21D, adjusts the display mode of the predetermined warning content so that it fits within the margin if the predetermined warning content does not fit within the margin. As a result, the user terminal 20 can display the predetermined warning content within the margin even if the amount of information in the predetermined warning content is large.

[0153] Furthermore, in the user terminal 20, the CPU 21, as a function of the management unit 21B, prohibits operations relating to editing of the caution content displayed on the drawing data, thereby preventing the user terminal 20 from altering the caution content corresponding to the caution point from the content stored in the caution point table and transmitting it to the user.

[0154] (Other) While the embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings, the technical scope of the present disclosure is not limited to such examples. It is clear that a person skilled in the art of the present disclosure can conceive of various modified or altered examples within the scope of the technical idea described in the claims, and it is understood that these modified or altered examples also naturally fall within the technical scope of the present disclosure.

[0155] Furthermore, the effects described in the above embodiments are explanatory or exemplary and are not limited to those described in the above embodiments. In other words, the technology according to the present disclosure may achieve other effects that are obvious to a person skilled in the art of the present disclosure from the description in the above embodiments, in addition to or instead of the effects described in the above embodiments.

[0156] In the above embodiment, the user terminal 20 is a "PC," but the user terminal 20 is not limited to this. For example, the user terminal 20 may be a mobile terminal such as a smartphone or a tablet.

[0157] In the above embodiment, the drawing database 44A, the annotation database 44B, and the authority database 44C are stored in the storage 44 of the server 40. However, this is not limiting. For example, the drawing database 44A, the annotation database 44B, and the authority database 44C may be stored in a distributed manner on the server 40 and a plurality of other servers.

[0158] In the above embodiment, an administrative user who manages the above authorities manually registers in the authority table, for each user registered in a predetermined application, no authority, only creation authority, only viewing authority, or both creation authority and viewing authority. However, this is not limited to this. For example, when user information (e.g., the department to which each user belongs) of each user is registered, any of the above authorities corresponding to the user information may be automatically registered in the authority table according to a predetermined rule.

[0159] In the above embodiment, an example has been described in which annotations for drawing data are created and edited by keyboard operations using a keyboard as the input unit 25. However, this is not limited to this. Creation and editing of annotations for drawing data may be performed by touch operations on the display unit 26 on which the drawing data is displayed, instead of or in addition to keyboard operations. The touch operations include operations using the user's finger on the touch panel of the display unit 26 and operations using an input device such as a touch pen. Thus, the user terminal 20 according to the above embodiment can improve the user's convenience regarding operations related to creating and editing annotations. Note that when an annotation for drawing data is created by touch operations, the creation operation is, for example, an operation of touching any position on the drawing data with a touch pen.

[0160] In the above embodiment, all of the predetermined annotations according to the viewing authority are displayed on the drawing data, but this is not limiting, and the user may be able to select the predetermined annotations to be displayed.

[0161] Fig. 20 is a seventh display example displayed on the display unit 26 of the user terminal 20. As an example, Fig. 20 shows drawing data displayed on the display unit 26 of the user terminal 20 owned by User A (see Fig. 5) who belongs to the design department, as a result of execution of the process shown in Fig. 13. Note that the following description will be given assuming that two annotations have been created for the drawing data shown in Fig. 20.

[0162] In the drawing data shown in FIG. 20, a selection field 70 for selecting an annotation to be displayed on the drawing data is added above the title field 53 in comparison with the drawing data shown in FIG.

[0163] The selection field 70 includes a first check box 71 , a second check box 72 , and a search box 73 .

[0164] The first check box 71 is a check box for selecting all annotations included in the drawing data to be displayed. Note that "all annotations" here refers to all predetermined annotations that can be viewed according to the viewing authority.

[0165] The second check box 72 is a check box for selecting some annotations included in the drawing data to be displayed. Note that "some annotations" here refers to some of the annotations among all the predetermined annotations that can be viewed according to the viewing authority.

[0166] The search box 73 is used to search for some of the annotations when a check mark is added to the second check box 72. User A can search for the desired annotation to be displayed on the drawing data by entering a specific user name or a specific department, etc., in the search box 73.

[0167] For example, when a check mark is placed in the first check box 71, the CPU 21 retrieves, from the annotation table shown in Fig. 12, annotation data for each record in which the drawing number of the drawing data shown in Fig. 20 is registered. On the other hand, when a check mark is placed in the second check box 72, the CPU 21 retrieves, from the annotation table, annotation data for each record in which the search criteria entered in the search window 73 (e.g., a specific user name) is registered.

[0168] Fig. 21 is an eighth display example displayed on the display unit 26 of the user terminal 20. As an example, Fig. 21 shows a state after user A has operated the selection field 70.

[0169] In the selection field 70 shown in Fig. 21, a check mark is added to the first check box 71. Therefore, the contents of all annotations included in the drawing data are displayed in the drawing data shown in Fig. 21. As an example, in Fig. 21, annotation information 83 is displayed below the component image 50, and annotation information 84 is displayed superimposed on the component image 51.

[0170] The annotation information 83 indicates the annotation content registered in the field of the column named "annotation content" corresponding to "annotation ID: 0001" in the annotation table shown in FIG. 12. In this case, the CPU 21 acquires, as annotation data for the annotation indicated by "annotation ID: 0001," information registered in the field of the column named with the column name of the coordinate values, annotation content, and character string corresponding to "annotation ID: 0001." The CPU 21 then displays the acquired annotation content in the direction of the acquired character string within a rectangular area whose vertices are the acquired four X and Y coordinate values. As a result, in the annotation information 83, the annotation content "tightening torque 32.0 to 35.5 Nm" is displayed horizontally in approximately the same position on the drawing data as the annotation information 60 in FIG. 11.

[0171] The annotation information 84 indicates the annotation content registered in the field of the column named "annotation content" corresponding to "annotation ID: 0002" (not shown) in the annotation table shown in FIG. 12. In this case, the CPU 21 acquires, as annotation data for the annotation indicated by "annotation ID: 0002," information registered in the field of the column named with the column names of the coordinate values, annotation content, and character string corresponding to "annotation ID: 0002." The CPU 21 then displays the acquired annotation content in the direction of the acquired character string within a rectangular area whose vertices are the acquired four X and Y coordinate values. As a result, the annotation information 84 displays the annotation content "(2) has been changed to a purchased item" in horizontal writing at approximately the same position on the drawing data created by the user who has been granted creation authority.

[0172] In the above, an example has been described in which a check mark is added to the first check box 71 in the selection field 70 shown in Fig. 21 . If a check mark is added to the second check box 72 in the selection field 70, the contents of some of the annotations extracted from the annotation table based on the search criteria (e.g., a specific user name) entered in the search window 73 are displayed. For example, if the search criteria entered in the search window 73 is "user X," only annotation information 83 indicating the annotation contents of annotations created by user X is displayed on the drawing data shown in Fig. 21 . In other words, in this case, annotation information 84 indicating the annotation contents of annotations created by users other than user X is not displayed on the drawing data.

[0173] In the above embodiment, the CPU 21 reduces the display size of the predetermined warning content as an adjustment to fit the display mode of the predetermined warning content within the margin, but the adjustment is not limited to this. For example, the CPU 21 may insert a line break in the text shown in the predetermined warning content while maintaining the display size of the predetermined warning content.

[0174] In the above embodiment, the creation authority is the authority to create a new annotation and to edit annotations, including updating and deleting the content of an already created annotation, but is not limited to this. For example, the creation authority may be the authority to only create a new annotation, and the authority to edit annotations, including updating and deleting the content of an already created annotation, may be a separate authority (e.g., editing authority).

[0175] In the above embodiment, the content of the text added to the drawing data as an annotation is registered in the field of the column named "annotation content" in the annotation table, but this is not limiting. For example, if a figure or symbol is added to the drawing data as an annotation, the content of the figure or symbol (e.g., a figure such as "circle", "triangle", or "square") is registered in the field.

[0176] In the above embodiment, the user terminal 20 executes the various processes shown in Figures 7, 8, 13, and 16. However, this is not limited thereto, and the various processes may be executed by the server 40. In this case, the server 40 is an example of the "information processing device" and "computer" of the present disclosure. In other words, the information processing system 10 may be configured as SaaS (Software as a Service) that executes software on the storage 44 of the server 40 via a web browser or the like running on the user terminal 20.

[0177] In the above embodiment, the various processes executed by the CPU 21 after reading software (programs) may be executed by various processors other than the CPU. Examples of such processors include programmable logic devices (PLDs) (such as field-programmable gate arrays (FPGAs)) whose circuit configuration can be changed after manufacture, and dedicated electrical circuits, such as application-specific integrated circuits (ASICs), which are processors having circuit configurations specifically designed to execute specific processes. Furthermore, the various processes may be executed by one of these various processors, or by a combination of two or more processors of the same or different types (e.g., multiple FPGAs, or a combination of a CPU and an FPGA). The hardware structure of these various processors is, more specifically, an electrical circuit that combines circuit elements such as semiconductor elements.

[0178] In the above embodiment, the information processing program 24A is pre-stored (installed) in the storage 24, but the present invention is not limited to this. The information processing program 24A may be provided in a form recorded on a recording medium such as a CD-ROM (Compact Disk Read Only Memory), a DVD-ROM (Digital Versatile Disk Read Only Memory), or a USB (Universal Serial Bus) memory. The information processing program 24A may also be downloaded from an external device via a network N. The technology disclosed herein may be applied to programs and program products.

[0179] All publications, patent applications, and technical standards mentioned in this specification are herein incorporated by reference to the same extent as if each individual publication, patent application, or technical standard was specifically and individually indicated to be incorporated by reference.
