Description

  The present invention relates to a display control device, a display control method, and a program.

  In recent years, referring to information by referring to a web page has been widely performed. Generally, a user uses a bookmark function when he / she wants to browse a web page once browsed. In recent years, a social bookmark function for supplying bookmarks at a plurality of terminals is also provided. However, the bookmark function generally stores the URL of the web page, and does not store the display position in the web page.

  When a user browses a web page once browsed, the user may want to resume browsing from the last read position. That is, the user may want to read the web page from the continuation. However, when browsing a web page with a large amount of information again, it is necessary to find a position that has been read up to the previous time, which is troublesome for the user.

  Patent Document 1 discloses a technique related to a display control method that also saves display position information when a bookmark is saved. In this display control method, the user performs a display position saving operation, and the currently displayed display position is saved in accordance with this operation. When the user refers to the bookmarked web page again, the page is displayed from the saved display position.

  Patent Document 2 discloses a technique related to a web browser capable of simultaneously browsing a large number of web pages. In this browser, the URL and the display position data currently being displayed are stored by the user explicitly performing a setting process (pressing a setting button). When the user refers to the saved URL, the page is displayed from the saved display position.

  Patent Document 3 discloses a display control device that detects a display position that is a home position of a web page that is frequently referred to by a user and displays the page from the home position when the web page is referred to.

  The HTML display / operation unit 2 downloads an HTML file and a file related to the HTML file from an arbitrary HTTP (hyper Text Transport Protocol) server. The HTML display / operation unit 2 is a processing unit that performs processing such as analysis of a downloaded file, configuration of display contents, display on a display unit (not shown), and input from a user. The HTML display / operation unit 2 is a processing unit having a function equivalent to that of a normal web browser.

  The operation analysis unit 3 is a processing unit that analyzes a user operation performed on the HTML display / operation unit 2. For example, the operation analysis unit 3 detects a change in the display position in the web page and a change in the web page to be browsed by the user's operation of the mouse or the like. When the operation analysis unit 3 detects a change in the display position in the web page, the operation analysis unit 3 starts processing of the display position acquisition unit 4, the displayed URL acquisition unit 5, and the display state storage unit 6. When the operation analysis unit 3 detects a change in the web page to be browsed, the operation analysis unit 3 starts processing of the display state search unit 8 and the displayed URL acquisition unit 5.

  The display position acquisition unit 4 acquires the display position in the currently displayed web page from the HTML display / operation unit 2 in response to the change notification of the display position of the web page from the operation analysis unit 3. Here, the display position is information indicating the number of bytes from the top of the <Body> element of the source of the HTML file, for example, the upper left position of the area displayed on the web browser. The display position acquisition unit 4 transmits the acquired display position to the display state storage unit 6.

  The displayed URL acquisition unit 5 acquires the URL of the currently displayed web page in response to the change notification of the display position in the web page from the operation analysis unit 3. The displayed URL acquisition unit 5 transmits the acquired URL of the currently displayed web page to the display state storage unit 6.

  The displayed URL acquisition means 5 acquires the URL of the browse web page after the change in response to the notification that the change of the web page to be browsed by the operation analysis means 3 is detected. The displayed URL acquisition unit 5 transmits the acquired URL to the display search unit 8.

  The display state storage unit 6 stores the display state information in the local database 7 in response to the display position change notification in the web page from the operation analysis unit 3. The display status information includes the display position in the currently displayed web page transmitted from the display position acquiring unit 4 and the URL of the currently displayed web page transmitted from the displaying URL acquiring unit 5. Associated information. That is, the display state storage unit 6 stores the URL and the display position in the local database 7 every time the display position in the web page is changed. Thereby, the local database 7 always stores the latest display position of the web page viewed by the user.

  The local database 7 is a database that stores display state information. A database table held by the local database 7 is shown in FIG. As shown in FIG. 2, the local database 7 stores a plurality of records in which the URL of each web page is associated with information on the display position.

  For example, when the display position of “http://www.hogehoge.com/page1.html” is changed to display the 100th byte from the <Body> tag, the display state storage unit 6 displays FIG. Update the table record as shown in.

  The display information search unit 8 searches the local database 7 for the display state information of the web page to be newly displayed in response to the notification that the change of the web page to be browsed is detected by the operation analysis unit 3. Here, the display information search means 8 uses the URL transmitted from the displayed URL acquisition means 5 as a search key. That is, the display information detection unit 8 searches the local database 7 for the latest display position of the web page to be newly displayed. The display information detection means 8 notifies the display position setting means 9 of the number of bytes of the display position as a search result. When the search result does not hit, the display information detection unit 8 does not notify the display position setting unit 9.

  In the example of FIG. 2, when the display of “http://www.hogehoge.com/page1.html” is started, the display information search means 8 starts searching the local database 7 using the URL as a key. The display information detection unit 8 notifies the display position setting unit 9 of “100 bytes” as a search result.

The display position setting unit 9 sets the display position of the web page to the display position notified from the display information detection unit 8. The display position notified from the display information detecting means 8 is information indicating the number of bytes from the head of the <Body> element of the source of the HTML file as described above. The display position setting means 9 instructs the HTML display / operation means 2 so that the position corresponding to the number of bytes is the upper left position of the screen.

  Note that the display position setting means 9 may confirm whether or not to resume the display from the display position nearest to the user via the HTML display / operation means 2. For example, the display position setting means 9 displays a confirmation pop-up on the display screen. When the user selects to restart the display from the latest display position, the display position setting unit 9 may set the display position of the web page to the display position notified from the display information detection unit 8. Thereby, the user can re-display the web page from the previous display position only when necessary.

  Next, the flow of display state information storage processing will be described with reference to FIG. FIG. 3 is a flowchart showing display state information storage processing by the display control apparatus 1.

  The user instructs the HTML display / operation unit 2 to perform processing. The operation analysis unit 3 analyzes whether or not the user operation performed on the HTML display / operation unit 2 is a change of the display position in the web page (S11). When it determines with it not being the change of the display position in a web page (S11: No), the display control apparatus 1 complete | finishes a process.

  On the other hand, when it is determined that the display position is changed in the web page (S11: Yes), the operation analysis unit 3 instructs the display URL acquisition unit 5 to acquire the URL of the web page being displayed. The displayed URL acquisition means 5 acquires the URL of the web page being displayed (S12). The operation analysis unit 3 instructs the display position acquisition unit 4 to acquire the display position after changing the display position. The display position acquisition unit 4 acquires the changed display position (S13). Note that the processes of S12 and S13 are out of order, and may be performed simultaneously.

  The display state storage unit 6 stores the information (display state information) acquired in S12 and S13 in the local database 7 (S14). When the information of the same URL has already been stored in the local database 7, the display state storage unit 6 overwrites and saves the record. Thereby, the local database 7 can hold | maintain the newest display state for every URL of the browsed web page.

  Next, with reference to FIG. 4, the flow of the display position setting process at the start of browsing the web page will be described. FIG. 4 is a flowchart showing a flow of a display position setting process at the start of browsing a web page.

  The user instructs the HTML display / operation unit 2 to perform processing. The operation analysis unit 3 analyzes whether or not the web page displayed by the user operation performed on the HTML display / operation unit 2 is changed (that is, browsing of a new web page) (S21).

  When it is not a change of a web page (S21: No), the display control apparatus 1 complete | finishes a process, without setting a display position.

  On the other hand, when the web page is changed (S21: Yes), the operation analysis unit 3 instructs the display URL acquisition unit 5 to acquire the URL of the web page being displayed. The displayed URL acquisition means 5 acquires the URL of the web page being displayed (S22).

  The display state search means 8 searches the local database 7 using the acquired URL as a key (S23). When there is no record having the same URL as the key URL (S24: No), the display control device 1 ends the process without setting the display position. As a result, display from the head portion of the web page is started as a result.

  On the other hand, when there is a record having the same URL as the key URL (S24: Yes), the display position setting means 9 sets the display position information of the record as the display position of the web page to be browsed (S25). .

  Then, the effect of the display control apparatus concerning this Embodiment is demonstrated. As described above, when the display position in the web page is changed, the display control device 1 sequentially stores the URL being browsed and the display position. When newly starting browsing of a web page, the display control apparatus 1 performs control so that browsing can be performed from the stored display position. As a result, when the user browses the web page, the user can browse from the previously referenced web page. Therefore, the user can recognize whether or not the user has browsed the web page, and the trouble of searching for the read portion is eliminated. Furthermore, since the user can browse from the previous browsing location, it is possible to prevent skipping of the web page.

  In the above description, the operation analysis unit 3 detects a change in the display position of the web page, and the display state storage unit 6 stores the display state information in response to the detection. However, the operation analysis unit 3 detects that the display position of the web page needs to be stored, and the display state storage unit 6 may store the display state information in response to the detection. For example, the operation analysis unit 3 detects the end of the display process (browser end process), the change of the web page to be browsed (the operation of the browser back button or forward button, the link click operation), and in response to the detection The display state storage unit 6 may store the display state information.

<Embodiment 2>
The display control apparatus according to the second embodiment of the present invention is characterized in that display state information is stored in an external server. With reference to FIG. 5, the basic configuration and operation of the display control apparatus according to the present embodiment will be described with respect to differences from the first embodiment. In FIG. 5, processing means having the same name and the same reference sign basically perform the same processing as in the first embodiment.

  The display control device 1 includes an HTML display / operation unit 2, an operation analysis unit 3, a display position acquisition unit 4, a displayed URL acquisition unit 5, a display state storage unit 6, a local database 7, and a display state search. Means 8, display position setting means 9, database selection means 10, and communication means 11 are provided. Furthermore, the external server 12 that can communicate with the display control device 1 includes a database 13 therein.

  The database 13 in the external server 12 has a configuration equivalent to that of the local database 7. The database 13 manages display state information on a table.

  The database selection means 10 selects a database that is a storage destination and a search destination of display state information. The database selection means 10 accesses the database 13 in the local beta base 7 or the external server 12 according to the setting made by the user.

  The communication unit 11 is a processing unit for controlling communication with the external server 12.

  In recent years, the full browser function of mobile phones and the spread of smartphones have made it possible to easily browse web pages while on the go or on the move. Under such an environment, for example, a case where a web page that has been browsed on a mobile phone while traveling is viewed again using a PC after returning home is assumed. According to the configuration described above, it is possible to share display state information among a plurality of terminal devices. For example, even when a web page browsed on terminal A is browsed again using another terminal B, the display position of the web page browsed on terminal A can be reproduced on terminal B.

<Embodiment 3>
The display control apparatus according to the third embodiment of the present invention is characterized by detecting whether or not a web page has been changed when browsing a previously displayed web page again, and responding to the change. With reference to FIG. 6, the basic configuration and operation of the display control apparatus according to the present embodiment will be described with respect to differences from the first embodiment. In FIG. 6, processing means having the same name and the same reference sign basically perform the same processing as in the first embodiment.

  The display control device 1 includes an HTML display / operation unit 2, an operation analysis unit 3, a display position acquisition unit 4, a displayed URL acquisition unit 5, a display state storage unit 6, a local database 7, and a display state search. Means 8, display position setting means 9, and hash value calculation means 14 are provided.

  When the operation analysis unit 3 detects a change in the display position in the web page, the operation analysis unit 3 starts the processing of the hash value calculation unit 14. Similarly, when the operation analysis unit 3 detects a change in the web page to be browsed, the operation analysis unit 3 starts processing of the hash value calculation unit 14.

  The hash value calculation unit 14 calculates a hash value from the data in the <Body> tag of the currently displayed web page in response to the change notification of the display position in the web page from the operation analysis unit 3. Any hash function may be used to calculate the hash value. The hash value calculation unit 14 notifies the display state storage unit 6 of the calculated hash value.

  The hash value calculation unit 14 calculates a hash value from the data in the <Body> tag of the browse web page after the change in response to the notification that the change of the web page to be browsed is detected by the operation analysis unit 3. The hash value calculation unit 14 notifies the display position setting unit 9 of the calculated hash value.

  The display state storage unit 6 stores the URL, the display position, and the hash value as display state information in the local database 7. FIG. 7 is a diagram showing a table of the local database 7 according to the present embodiment. As illustrated, each record includes a URL, a display position, and a hash value.

  The display information search unit 8 searches the local database 7 for the display state information of the web page to be newly displayed in response to the notification that the change of the web page to be browsed is detected by the operation analysis unit 3. The display information search means 8 notifies the display position setting means 9 of the hash value in addition to the display position as a search result.

  The display position setting unit 9 determines whether or not the hash value transmitted from the hash value calculation unit 14 and the hash value transmitted from the display information search unit 8 are the same. That is, the display position setting unit 9 determines whether or not the hash value generated at the previous browsing is the same as the hash value generated at the current browsing. By checking the identity of the hash value, it is possible to grasp whether or not the web page has been changed. If they are the same, the same processing as in the first embodiment is performed.

  If the hash values are not the same, the display position setting unit 9 does not set the display position of the web page.

  If the web page is changed after the user browses the web page, the position desired by the user cannot be displayed again even if the display position at the time of the most recent display is stored. However, according to the above-described configuration, it is possible to detect whether or not there is a change from the web page when it was previously displayed. Thereby, when the change of the web page has arisen, the setting of a display position can be invalidated and browsing from an incorrect display position can be prevented.

  If the web page has changed, the user is inquired whether to set the display position, and the display position setting means 9 switches whether to set the display position according to the inquiry result. May be.

  Further, the display control device 1 may have the following functions. In general, the hash value takes a different value when the data in the <Body> tag of the web page is changed even by 1 byte. Therefore, even if it is a change of several bytes, the display position is not set in the above configuration. In order to cope with this, the display position acquisition unit 4 acquires a character string of several bytes around the display position. The display state storage unit 6 stores the acquired character string of several bytes around as the display state information.

  When it is determined that the hash values are different, the display position setting unit 9 determines whether or not the character string of several bytes stored in the local database 7 is in the web page to be displayed. When the display position setting means 9 determines that the character string exists in the web page to be displayed and the position of the character string is close to the display position stored in the local database 7, the display position setting unit 9 I do. Thereby, the display control apparatus 1 can set the display position of a web page, without being influenced by the slight change of a web page.

  Note that the present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention. For example, the technique of the present invention can be applied to document browsing and editing software. For example, when the technique of the present invention is applied to a word processor, the previous editing position can be automatically displayed. Thereby, the burden of editing work can be reduced. In this case, the file name of the document may be stored in the local database 7 instead of the URL information shown in FIG.

  When the upper left position of the display area of the screen is the middle part of the image, with the above configuration, the upper left position of the image is always set as the display position at the time of redisplay. This is because, in the above configuration, the position where the tag for displaying the image is stored is stored, and information on the location of the image is not included. In this case, for example, the display control apparatus records not only the position information in the HTML file but also the relative coordinates (X, Y) from the upper left of the currently displayed image as the display state information. At the time of redisplay, the display position is reproduced using the relative coordinates, so that the previous display position can be accurately reproduced.
