If the user designates any two feature points with the pointer 70 with reference to such a screen display, the client device 29 refers to the coordinates of the designated two feature points and Calculate the linear distance between the coordinates.

When the distance between the feature points is obtained, the client device 29, as shown in FIG. 11, places a portion corresponding to the previously designated feature point on the three-dimensional model displayed in the display area 54, A leader line is drawn, and a number corresponding to the calculated dimension is displayed.

According to such processing, by designating any two points of the three-dimensional model, the dimensions thereof can be known. In the above example, the dimension between two points is displayed. However, the dimension between three points or more is displayed,
Alternatively, it is also possible to display the distance of the curve and the radius of curvature thereof.

Next, the operation when the button 55k is operated will be described. After the pointer 70 is moved over the button 55k and a predetermined operation is performed, as shown in FIG. 12, when a part of the three-dimensional model is designated by the pointer 70, the client device 29 moves to the designated part. From the WEB server 28, three-dimensional data relating to the corresponding component, which is a replacement unit, is acquired.

In the example shown in FIG. 12, since the operation buttons on the front panel are designated by the pointer 70,
The client device 29 converts the three-dimensional model corresponding to the button assembly, which is the unit of exchange of the designated operation button, into a W
Obtained from the EB server 28. Then, it is displayed on the display area 54 of the screen 50.

FIG. 13 is an example of a screen displayed on the display device of the client device 29 as a result of the above processing. In this example, the display area 54 of the screen 50 is
The three-dimensional model of the button assembly, which is the unit of exchange of the button specified by, is displayed.

In this example, only the three-dimensional model of the button assembly is displayed.
For example, the price of the part, the replacement procedure, and the repair cost and the number of repair days required when the repair is requested may be displayed. With such a display,
This allows the user to replace the parts by himself or to know beforehand how much cost and the number of days are required in the case of sending out the repair, which can be useful for the user.

In addition, a repair request or an order for a part may be continuously performed on the same screen together with the part to be replaced. According to such a process, the trouble of separately contacting the manufacturer can be omitted.

Next, the operation when the button 551 is operated will be described. As shown in FIG.
Assuming that the pointer 70 has been moved upward and a predetermined operation has been performed, the client device 29 acquires from the WEB server 28 a three-dimensional model indicating the internal structure of the product. Then, it is displayed in the display area 54.

As a result, as shown in FIG. 14, a three-dimensional model showing the internal structure of the product is displayed in the display area 54. Note that the three-dimensional model showing the internal structure can be displayed in an arbitrary display mode using the buttons 55a to 55i, similarly to a normal three-dimensional model. It becomes possible to understand. Also, if the use of the buttons 55j to 55p is permitted, it is possible to know the dimensions of internal parts and other information in more detail.

In the above embodiment, for example, a user at user level 3 cannot browse a three-dimensional model of such an internal structure, but, for example, a mask (for example, a part (Deletion or filling).

Next, the operation when the button 55m is operated will be described. As shown in FIG.
When the pointer 70 is moved to a position on the sub-screen 8 shown in FIG.
0 is displayed, and image data to be displayed on the sub screen 80 is obtained from the WEB server 28.

Subsequently, when a portion corresponding to an operation button or the like of the three-dimensional model is operated by the pointer 70, the image data displayed on the sub screen 80 is changed corresponding to the portion. For example, as shown in FIG.
When the jog dial portion of the dimensional model is rotated clockwise by the pointer 70, the image displayed on the sub screen 80 is fast-forwarded. When an operation of rotating in the counterclockwise direction is performed, the image displayed on the sub screen 80 is rewound. Further, at this time, the time display displayed on the upper right of the sub screen 80 also changes according to the operation.

As described above, if the sub-screen 80 is displayed on the display device of the client device 29 and the display content of the sub-screen 80 is changed in conjunction with the operation of the operation unit of the three-dimensional model, It is possible to assist the user in understanding individual and specific functions such as the operation unit.

Next, the operation when the button 55n is operated will be described. As shown in FIG.
When 0 is moved to the button 55n and a predetermined operation is performed, the client device 29 is in a state of waiting for input.

In such a state, for example, FIG.
19, when the jog dial of the three-dimensional model is designated and, for example, a mouse button (not shown) is right-clicked, a menu screen 81 as shown in FIG. In this example, “color change” and “text change” as attributes are displayed as selection items.

Here, the color change is an item selected when changing the color of a predetermined part or area of the three-dimensional model. The text change is an item that is selected when the text (for example, text indicating the sights of each part) included in the three-dimensional model is changed.

In the menu screen 81, for example, when "change color" is selected, a sub-screen for color selection (not shown) is displayed, and a predetermined color is selected from a plurality of sample colors displayed on the sub-screen. When selected, as shown in FIG.
The front side of the previously designated jog dial will be filled with the selected color.

In this example, the color change has been described. For example, it is assumed that, after the text "POWER" displayed on the upper left of the front panel is selected, "text change" is designated on the menu screen 81. ,
A new sub-screen for text entry is displayed, allowing you to change to any text (eg, "power").

As described above, since a predetermined area of the three-dimensional model is designated and a desired item is selected on the menu screen 81, the display color and text of the three-dimensional model can be changed. It is possible to change the three-dimensional model so as to meet the taste.

The contents changed as described above are stored in the WEB by operating the button 53 as described later.
Since it is possible to feed back to the server 28, it is possible to reliably feed back the opinion of the user to the manufacturer.

Next, a case where the button 55o is operated will be described. After the button 55o is operated, as shown in FIG. 21, if a predetermined area of the three-dimensional model is designated by the pointer 70, the sub screen 90 shown in FIG.
Is displayed, so that the user can input a comment for the designated place.

In the example of this figure, the comment "I think that operability is improved by making the stop button a little larger" is input to the sub screen 90. When the "OK" button at the bottom of the sub-screen 90 is operated after inputting a predetermined comment in this way, the input comment includes information for specifying the specified part of the three-dimensional model. They will be stored in association with each other.

Then, as described later, when the button 53 is operated, the input comment is transmitted to the WEB server. It becomes possible to know the comment in association with the part related to the comment.

Next, the case where the button 55p is operated will be described. After the button 55p is operated, as shown in FIG. 23, assuming that a predetermined area of the three-dimensional model is designated by the pointer 70, the client device 29
Help information corresponding to the specified part is provided on the WEB server 2
8 and the sub-screen 100 is activated and displayed there, as shown in FIG. In this example, a sub screen 100 entitled "Help" is displayed, and a comment "a button for temporarily canceling an external control signal" is displayed in the display area.

As described above, by designating a predetermined part of the three-dimensional model, it is possible to display help information on the part. As a result, it is possible to quickly reach desired information. In addition, by performing statistical processing on the number of times the help information is referred to by the processing described later, it becomes possible for a manufacturer to easily know a part that is difficult for many users to understand in common.

In the above embodiment, only text information is displayed, but it is also possible to output image, moving picture, and audio information. Next, processing when the button 53 is operated will be described.

As a preceding stage, when the button 55n, the button 55o, or the button 55p is operated, the client device 29 generates a log file and records the contents of the operation. Such a log file is stored in the WE when the button 53 is operated.
It is transmitted to the B server 28 together with the user ID and the like.

In the WEB server 28, the received log file, user ID and the like are stored in a table (HDD) shown in FIG.
28d) is stored. In this example, a user ID, a user level, a help log, and a comment log are stored in association with each user.

Here, the user ID and the user level are the same as those in FIG. Help log is button 5
5p is a log created when an operation is performed, and is composed of an operation date and time and a part (part targeted for operation) as described later.

The comment log is a log created when the button 55o is operated, and includes an operation date and time, a site, and a comment log as described later. FIG.
FIG. 5 shows details of the help log and the comment log.

FIG. 25A shows a help log. In this example, the date and time when the button 55p was operated and the target part are stored in association with each other. FIG. 25 (B)
Is a diagram showing a comment log. In this example, the date and time when the button 55o was operated, the site, and the file name of the comment log file storing the comment input on the sub screen 90 shown in FIG. 22 are stored in association with each other.

FIG. 25C is a diagram showing an example of a comment log file in which comments are stored. In this example, the comment "I think that the operability is improved by making the stop button a little larger" is stored which is input on the sub screen 90 shown in FIG.

In this way, the client devices 29 to 3
1 is stored in the HDD 28d of the WEB server 28. Such information can be referred to by accessing the client devices 21 to 23, for example.

For example, if the client devices 21 to 23
When the log information generated in this way is subjected to statistical processing and displayed in association with the three-dimensional model, for example, a screen 130 as shown in FIG. 26 can be obtained.

In this display example, a screen 130 entitled "Browser" is displayed, and a WEB
Buttons 131 operated to acquire a log file of a predetermined three-dimensional model from the server 28 are displayed. The display area 132 includes the web server 28.
The result of statistical processing of the log file obtained from
It is displayed in association with the three-dimensional model.

That is, in this display example, the total number of times the help file for each part of the three-dimensional model has been referred to is displayed for each part. By referring to such a screen 130, the manufacturer can know which part of the operation is difficult for the user to understand, so that it can be used as a guideline when developing a new product. Become.

In the above example, the help file has been described as an example. However, for example, it is also possible to display the input comments by classifying them according to their contents or parts. According to such a display, the manufacturer can know which part has a high demand.

Further, when the button 55n is operated, its contents are also stored as a log file, and the log file is collected and statistically processed.
You may make it classify and display for every site | part. By referring to such a display, it becomes possible to know what attribute (for example, color) the user desires for each part of the product.

In the above example, when the button 53 is operated, the log information is transferred to the WEB server 28. However, instead of such a button operation, the log information is transmitted for a predetermined time. When the time has elapsed, the log information may be automatically transferred to the WEB server 28.

Next, the operation when the button 52 is operated will be described. The button 52 is operated, for example, when the user and the manufacturer share the same three-dimensional model on a screen and want to exchange information via the three-dimensional model.

First, considering the case where the button 52 has been operated on the client device 29, the client device 29 indicates that the button 52 has been operated on the WEB.
The server 28 is notified. As a result, the WEB server 28 reads a predetermined HTML file from the HDD 28d and transmits it to the client device 29 that has made the request.

As a result, a screen as shown in FIG. 27 is displayed on the display device of the client device 29. In this display example, the title “list of conference rooms” and buttons 110 to 113 indicating the usage status of the conference rooms and the like are displayed. Here, the conference room is, for example, CGI (Common Gateway)
Interface), the user and the manufacturer are the same 3
It means a virtual "meeting room" that uses a dimensional model as an interface to exchange information.

In this example, there are four conference rooms 01 to 04, of which the conference rooms 02 and 03 are in use by the button state “in use”.

If the user operates the button 110 on such a screen 50, the WEB server 28
The HTML file corresponding to the conference room 01 is transmitted to the client device 29, and the corresponding script is executed.

Next, assuming that the manufacturer logs in to the same conference room 01 as the user via the client device 21, the client device 21
8 is displayed.

In such a state, the script of the WEB server 28 detects an operation performed on the client device 21 and transmits it to the client device 29, and conversely,
The operation performed on the client device 29 is detected and transmitted to the client device 21. As a result, the three-dimensional model changes according to both operations.

In the example of FIG. 28, two pointers, a pointer 70 and a pointer 120, are displayed. The pointer 70 is a pointer corresponding to the operation of the client device 29, and the pointer 120 is a pointer. This is a pointer corresponding to the operation of the client device 21.

In such a screen, for example, if the user operates the button 55o and inputs a comment “There is a dent in this part” as shown in FIG. Are displayed on the display device of the client device 21 on the manufacturer side via the WEB server 28 in the same manner.

Therefore, according to such an embodiment,
The user and the manufacturer can share the same three-dimensional model and exchange information with each other while referring to the three-dimensional model. It becomes possible to exchange information.

In the above embodiment, only the image and the text information are exchanged, but the audio and the moving image may be exchanged together.
