User operation information saving processing and content redisplay processing will be described below.

First, an example of a processing procedure of user operation information saving processing will be described with reference to the sequence chart shown in FIG.

Here, it is assumed that the first web content is displayed in the browser window on the terminal device 2 (step S11). Although detailed explanation is omitted, for example, when a content specifying operation is performed to specify the first Web content (input a URL indicating the first Web content) in a predetermined area of the browser window, the terminal device 2 The web server 3 is requested to provide the first web content, and the web server 3 generates web content information for displaying the first web content. The first web content is displayed in the browser window on the terminal device 2 based on the web content information generated by the web server 3 in this way.

Here, the user using the terminal device 2 can perform a content display change operation on the first Web content displayed in the browser window. When a content display change operation is performed on the first Web content in this manner, the operation accepting unit 21 accepts the content display change operation (step S12).

When the process of step S12 is executed, the web content display unit 23 changes the display of the first web content in the browser window based on the content display change operation accepted in step S12 (step S13).

Next, for example, it is assumed that the operation accepting unit 21 accepts the content specifying operation by the user performing a content specifying operation to specify web content other than the first web content (hereinafter referred to as second web content). . In this case, the update detection unit 22 detects an update of the display of the browser window (transition from the web page including the first web content to the web page including the second web content) (step S14).

When the update of the display of the browser window is detected in step S14, the update detection unit 22 requests (display of) the second web content designated by the content designation operation from the web server 3 (step S15).

When the process of step S15 is executed, the update processing unit 32 included in the web server 3 acquires the second web content requested in step S15 from the web content storage unit 31, and displays the second web content. is generated (step S16).

The web content information generated in step S16 is transmitted from the web server 3 (update processing unit 32) to the terminal device 2 (step S17).

The web content information transmitted from the web server 3 in step S17 is received by the terminal device 2, and the web content display unit 23 displays the second web content in the browser window based on the web content information (step S18).

Here, the user operation information extraction unit 25 included in the terminal device 2 extracts the user operation information indicating the user's operation (content display change operation) received by the operation reception unit 21 as the content display change operation performed. It is assumed that the Web content is held (accumulated) in association with the content ID for identifying the Web content. In this case, the user operation information extracting unit 25 extracts user operation information indicating a content change operation performed on the first Web content (hereinafter referred to as user operation information related to the first Web content) from among the held user operation information. notation) is extracted (step S19). Note that the user operation information extracted in step S19 corresponds to the content display change operation received in step S12.

Note that the processes of steps S12 and S13 described above may be executed a plurality of times (that is, the user performs a content display change operation a plurality of times). Any user operation information may be used as long as it indicates the content display change operation received (the most recent content display change operation). However, if, for example, the display state of the first web content has been reached before the process of step S14 is executed through a plurality of content change operations, after the first web content is displayed in step S11, in step S14 User operation information indicating all content display change operations performed on the first Web content by the user until the update of the display of the browser window is detected may be extracted.

The user operation information extracted in step S19 is transmitted from the terminal device 2 to the web server 3 together with the content ID for identifying the first web content (step S20).

The user operation information management unit 33 included in the Web server 3 receives the user operation information and the content ID transmitted from the terminal device 2 in step S20, associates the received user operation information with the content ID, and provides the user with the content ID. Stored in the operation information storage unit 34 (step S21).

According to the user operation information saving process described above, the user operation information indicating the content display change operation performed on the first Web content can be saved in the Web server 3 .

In the present embodiment, the user operation reflection mode is set according to the user's mode setting operation, but the processing of steps S19 to S21 is executed only when the user operation reflection mode is set. may In this case, the user operation information extraction unit 25 refers to the mode setting flag held in the mode setting unit 24 so that the user operation reflection mode is set (that is, the user operation reflection mode is ON). If it is determined that, the process of step S19 may be executed. On the other hand, if it is determined that the user operation reflection mode is not set (that is, the user operation reflection mode is OFF), the process of step S19 is not executed.

Also, in FIG. 7, it is assumed that the user operation information is saved in the Web server 3 in response to a content designation operation, for example, but the saving processing of the user operation information (that is, the processing of steps S19 to S21) is , may be executed when an operation different from the content specifying operation (an operation instructing to save the user operation information in the Web server 3) is performed.

Furthermore, in FIG. 7, the processes are described as being executed in the order of steps S11 to S21, but the processes of steps S19 to S21 may be executed after the process of step S13 is executed, for example. That is, the processing of steps S19 to S21 may be executed at the timing when an operation instructing to save the user operation information in the web server 3 is performed, or may be executed in parallel with the processing of steps S14 to S18. may be

Next, an example of the processing procedure of content redisplay processing will be described with reference to the sequence chart of FIG. 8 is executed after the process shown in FIG. 7, and the second Web content is displayed in the browser window on the terminal device 2 here.

Here, for example, it is assumed that the operation accepting unit 21 accepts the content specification operation by the user performing the content specification operation of specifying the first web content in order to redisplay the first web content. In this case, the update detection unit 22 detects an update of the display of the browser window (transition from the web page including the second web content to the web page including the first web content) (step S31).

When the update of the display of the browser window is detected in step S31, the update detecting unit 22 requests the web server 3 to (display) the first web content designated by the content designation operation (step S32).

When the process of step S32 is executed, the user operation information management unit 33 included in the web server 3 refers to the user operation information storage unit 34, and the user operation information related to the first web content requested in step S32 (that is, , user operation information associated with the content ID for identifying the first Web content) exists in the user operation information storage unit 34 .

When it is determined that user operation information related to the first Web content exists, the user operation information management unit 33 acquires the user operation information from the user operation information storage unit 34 (step S33). A plurality of pieces of user operation information may be acquired in step S33.

When the process of step S33 is executed, the update processing unit 32 acquires the first web content requested in step S32 from the web content storage unit 31, based on the user operation information acquired in step S33. Web content information for displaying the first Web content whose display is changed according to the content display change operation during the user operation information saving process shown in FIG. 2 is generated (step S34). Note that the Web content information generated in step S34 displays the first Web content reflecting the content display change operation performed on the first Web content previously displayed in the browser window (that is, the previous Web content information). Web content information for reproducing or restoring the display state of the first Web content.

The web content information generated in step S34 is transmitted from the web server 3 (update processing unit 32) to the terminal device 2 (step S35).

The web content information transmitted from the web server 3 in step S35 is received by the terminal device 2, and the web content display unit 23 displays the first web content in the browser window based on the web content information (step S36).

According to the above-described content redisplay process, the second web content is displayed after the content display change operation is performed, for example, by enlarging the first web content, and the first web content is redisplayed after the second web content is displayed. Even in such a case, it is possible to display the first web content already enlarged based on the content display change operation (that is, the first web content to which the content display change operation is reflected). .

Although the case where user operation information related to the first Web content exists has been described here, when the user operation information does not exist, the process of step S33 is not executed, and the processes of steps S34 to S36 are executed. . In this case, the first web content in the initial state is displayed within the browser window.

Also, although omitted in FIG. 8, the processing of step S33 is assumed to be executed when the user operation reflection mode is set. Whether or not the user operation reflecting mode is set can be determined by referring to the mode setting flag held in the mode setting unit 24 included in the terminal device 2 as described above. In this case, the user operation information management unit 33 acquires (receives) the mode setting flag from the terminal device 2 (mode setting unit 24) to determine whether or not the user operation reflection mode is set. . If the user operation reflection mode is not set, the process of step S33 is not executed, and the first web content in the initial state is displayed in step S36 (that is, the first web content is displayed without reflecting the content display change operation). display content).

As described above, in this embodiment, the web server 3 generates web content information (first content information) for displaying the first web content, and the terminal device 2 displays the first web content based on the web content information. and changes the display of the first Web content according to the user's content display change operation for the first Web content. In this case, in the present embodiment, the web server 3 stores user operation information indicating content display change operations for the first web content in the user operation information storage unit 34 . Further, in the present embodiment, when the first Web content is redisplayed on the terminal device 2, the Web server 3 changes the display (from the initial state) based on the user operation information stored in the user operation information storage unit 34. Web content information (second content information) for displaying the changed first Web content is generated, and the terminal device 2 displays the first Web content based on the Web content information.

In the present embodiment, with the configuration described above, when the first Web content is redisplayed, the first Web content can be displayed in a state in which the previously performed content display change operation has already been reflected. Convenience can be improved. In other words, in the present embodiment, the user's operation state (application operation state) for Web content is retained, and the display control of Web content based on the operation state is realized, thereby preventing the loss of the content once operated by the user. It is possible to avoid the trouble of repeating the same operation when re-displaying the Web content.

Note that FIGS. 7 and 8 described above assume a case where the web contents (web pages) displayed in the browser window transition in the order of the first web content, the second web content, and the first web content. Any configuration may be used as long as the first web content is displayed in a manner that reflects the content display change operation performed on the first web content when the first web content is redisplayed. That is, the present embodiment may be applied to a case where the first web content is redisplayed after a plurality of other web content is displayed, or the first web content for which a content display change operation has been performed is displayed. It may be applied to a case where the first web content is redisplayed (that is, the web page including the first web content is reloaded). Note that when the web page including the first web content is reloaded, the reload is detected as an update of the display of the browser window in step S14 shown in FIG. After the processes are executed, the processes of steps S19 to S21 are executed, and then the processes of steps S32 to S36 shown in FIG. 8 are executed.
