In the following description, among the pages displayed in the window screen, the information display area is referred to as a content display section, and the label display area is referred to as a label section.

As shown in FIG. 5A, the present embodiment is characterized in that a label portion is formed separately from a content display portion for displaying the content of information in an area for displaying a page. The content display section is displayed in a hypertext format. The label section displays the title stored in the access history table 16 in association with the information displayed on the content display section. In FIG. 5A, information that the page title is “Company A homepage” is displayed, and “Greetings”, “Guidance of Company A”,
The display part of "Product introduction" is a switch for switching the display to another page. Here, when the mouse pointer is clicked in conjunction with "Product Introduction", the page is displayed as shown in FIG. 5B.

The feature of this embodiment is that new information is added to the display screen (here, "Introduction of product").
Is displayed, the display area of "product introduction" is arranged at a position where the display content of the label part of the displayed information (here, "Company A homepage") can be confirmed. . In other words, the page "Introduction of product" is displayed in such an image as to be overlapped with the label part of "Company A homepage" slightly shifted. For this reason, the label portion of each display area is always displayed and the image is displayed in the order of access. As described above, the label portion is provided in the display area of each page, and the display content of the label portion displayed in the past can be always confirmed as the access history, so that the type of information displayed in the past can be easily confirmed. Can be. Note that the subsequent transition in the display screen using FIG. 5 will be described later.

Next, the processing according to the present embodiment will be described with reference to the flowcharts shown in FIGS. The characteristic processing of the present embodiment can be roughly classified into a display processing of a new page, a display processing of an existing page (page switching processing), and a deletion processing of an existing page. Explanation will be given along the screen transition.

In FIG. 6, the processing determining unit 13 extracts an event stored by the input / output control unit 11 from the event queue 12 (step 101), and determines whether the event is based on a mouse click (step 102). If the event is not based on a mouse click, a process based on the event is performed. However, the process performed here is not the gist of the present invention, and thus the description is omitted (step 103). On the other hand, if it is based on a mouse click, the processing determination processing shown in FIG. 6 is performed (step 104).

In FIG. 7, when the mouse is clicked on the content display unit with reference to the location where the event occurred, the process determination unit 13 determines the process when the content display unit is clicked (steps 111 and 112). When the mouse click is performed on the label portion, the processing at the time of clicking the label portion is determined (steps 113 and 114). When the mouse is clicked in the menu, the processing at the time of menu click is determined (steps 115 and 116). The process performed when the mouse is clicked at another place is not the gist of the present invention, and the description thereof is omitted (step 11).

Here, the processing determination at the time of clicking the content display section in step 112 will be described with reference to the flowchart shown in FIG.

The processing determining unit 13 determines whether a mouse click has been performed on a hypertext switch in the content display unit (step 121). Based on FIG. 5A, this corresponds to a determination as to whether any of the switches of “greeting”, “information of Company A”, and “product introduction” has been selected. If the mouse is clicked at a place other than the switch, other processing according to the selection is performed (step 122). When performed for the switch, it is determined whether the selected link destination exists in the access history (step 123). This is performed by referring to whether the link destination address linked by the selection of the switch is registered in the access history table 16.
If the link destination address is not registered, a new page display instruction is issued to the processing execution unit 14 (step 124). If the link destination address is registered, an existing page display instruction is issued to the processing execution unit 14. (Step 125).
When issuing this instruction, the processing determination unit 13 stores the link destination address in the delivery information buffer for the processing instruction.
The link destination address is included in the page configuration information of the “Company A homepage” received via the communication control unit 15.

Next, the processing when a new page display command is issued (new page display processing) will be described with reference to the flowchart shown in FIG.

First, the processing execution unit 14 is provided with the processing determination unit 13
When a new page display instruction is received from, a title is taken out from each record in the order of older access date and time with reference to the access history table 16 to create an image in which pages displaying only the label portion are superimposed and displayed (step 13).
1). Of course, when the pages are overlapped, the display content of the label portion is made visible. Then, the processing execution unit 14 extracts the link destination address from the delivery information buffer for the processing instruction, and passes it to the communication control unit 15 (step 13).
2). Then, the communication controller 15 communicates and receives H
Based on page configuration information such as TML and images, an image of a title to be displayed on a label portion of a page located at the highest position in a page group and an image of information to be displayed on a content display portion are created (step). 133). Thereafter, the process execution unit 14 creates a record of access history information in which the page title is set as the title, the link destination address is set as the address, and the current time is set as the access date and time based on the received page configuration information, and the access history table is created. Is newly registered (step 134). Processing execution unit 14
Transmits the image information created as described above to the input / output control unit 11. The input / output control unit 11 displays the image information on the display device 2 (Step 135).

The above processing will be described with reference to the display example shown in FIG. 5. When the switch "Introduction of product" is selected in FIG. 5 (a), the processing execution unit 14 sets the access history table 16 , The title "Company A homepage" is extracted, and an image of the label portion of each page is created. When this process is performed for the first time, only a record relating to “Company A homepage” is registered in the access history table 16. After that, based on the received page configuration information of “product introduction”, an image of a label portion displaying “product introduction” and an image of a content display portion displaying each switch are created. As a result, the displayed contents are as shown in FIG. Further, when “TV” is selected from the page “Product introduction”, the processing execution unit 14 extracts the title “Company A homepage” and “Product introduction” from the access history table 16 and Create an image of the label section. Then, based on the received page configuration information of “TV”, an image of a label portion displaying “TV” and an image of a content display portion displaying each switch are created. As a result, the displayed contents are as shown in FIG.
Similarly, from the page “TV”, “TV-001”
When "type" is selected, the contents of FIG. 5D are displayed.

As described above, according to the present embodiment, since the label portion which is always displayed is provided, it is possible to recognize at a glance the type of information displayed on each page in the past. In addition, since the selected pages are displayed as superimposed images, the context of the displayed pages can be known at a glance. By regarding the displayed display screen as a document stacked in the order of access, a sense of unity between the history and the displayed contents is generated, and a friendly user interface can be provided.

Next, the processing when the label portion is clicked (step 114 in FIG. 7) will be described with reference to the flowchart shown in FIG. This process is a process when the display content is switched from FIG. 5D to FIG. 5E, and the existing page display process (page switching process) which is one of the characteristic processes of the present embodiment. Is equivalent to

First, the processing determination unit 13 determines which label of the page the mouse click was performed with reference to the location where the event occurred (step 141). The result of this determination (page identification information) is stored in the processing information delivery information buffer for subsequent processing. Next, the processing determination unit 13 determines which button has been clicked with reference to the detailed information of the event (step 142). In the case of the right button, a menu display instruction is issued to the processing execution unit 14 (step 143), and if registered, an existing page display instruction is issued to the processing execution unit 14 (step 144).

Here, the processing when the existing page display command is issued will be described with reference to the flowchart shown in FIG.

First, the processing execution section 14 is provided with the processing determination section 13
When an existing page display instruction is received from, a title is taken out from each record up to the designated page with reference to the access history table 16 in the order of the access date and time, and an image is displayed in which only the label portion is displayed in a superimposed manner. (Step 151). Of course, when the pages are overlapped, the display content of the label portion is made visible. Which page is specified is stored in the delivery information buffer for the processing instruction. Then, the processing execution unit 14 extracts the page address from the record (access history information) of the specified page, and passes it to the communication control unit 15 (Step 152). Then, based on page configuration information such as HTML and images received by the communication control unit 15 through communication, an image of a title to be displayed on the label portion of the topmost page in the page group is displayed. An image of the information to be displayed on the section is created (step 153). Further, the processing execution unit 14 refers to the access history table 16, extracts titles from records from the next record to the latest record of the specified page in the order of the access date and time, and creates an image of only the label portion. (Step 154). However, the display position of the label portion at this time starts from the right end of the content display portion of the page displaying the content of the information. Of course, also in this case, the display content of the label portion is made visible. The processing execution unit 14 transmits the image information created as described above to the input / output control unit 11.
The input / output control unit 11 displays the image information on the display device 2 (Step 155).

The above processing will be described with reference to the display example shown in FIG. 5. When the label section "Introduction of product" is selected in FIG. 5D, the processing execution section 14
The titles "Company A homepage" and "Product introduction" are extracted from the access history table 16, and an image of the label portion of each page is created. Then, an image of the content display section of “product introduction” is created based on the received “product introduction” page configuration information. Further, the processing execution unit 14 determines from the access history table 16 that the titles “TV”, “T”
V-001 "is taken out, and an image of a label portion of" TV "or" TV-001 "is created at the right end position of the content display section of" Introduction of product ". As a result, the displayed content is as shown in FIG.

As described above, according to the present embodiment, by selecting the label using the mouse 1, it is possible to switch to the content display of the information of the page corresponding to the label. And the label part of the information before the specified page, that is, the information older than the specified page, is on the left side of the page,
After the designated page, that is, the label portion of the new page is always displayed side by side on the opposite side. If you treat the pages in the display screen as documents stacked in the order of access, you can see the contents of the specified page as if it were just opened, giving a sense of unity between the history and the displayed contents, and a friendly user interface Can be provided. Further, the label part of the page opened in the past is always displayed, and the page opened in the past can be easily opened by only one operation of clicking the mouse on any one of the label parts.

The above processing is performed in step 125 of FIG.
This is a common process. For example, if the switch "TV" is clicked in FIG. 5E, the information of the page "TV" is displayed.

Finally, a description will be given of the menu display instruction processing (step 143 in FIG. 10) issued when the label part is clicked with the right button in the processing when the label part is clicked. This corresponds to an existing page deletion process, which is one of the characteristic processes of the present embodiment.

When the right button is clicked on the label portion and the menu display command of step 143 is issued, the process execution section 14 displays the menu 17 as shown in FIG. The present embodiment is characterized in that a command for a display area corresponding to the label portion can be received by selecting the label portion in this manner. In the case of the present embodiment, the menu 17 is opened by a selection operation. This menu 17 includes at least “delete” for executing the page deletion process.

In FIG. 7, when it is determined that the menu 17 has been clicked by referring to the location where the event has occurred, the processing determination unit 13 determines the processing at the time of menu click (steps 115 and 116).

Here, the processing determination at the time of menu click in step 116 will be described with reference to the flowchart shown in FIG.

The processing determining unit 13 determines which item in the menu has been clicked with the mouse by referring to the place where the event occurred (step 161). When the mouse click is performed on the delete item, an existing page delete instruction is issued to the processing execution unit 14 (steps 162 and 16).
3). The processing when the mouse is clicked on another item is not the gist of the present invention, and thus the description is omitted (step 164).

Next, processing when an existing page deletion instruction is issued will be described with reference to the flowchart shown in FIG.

First, the processing execution section 14 is provided with the processing determination section 13
When an existing page deletion instruction is received from, it is determined whether the page specified as the deletion target is currently being displayed (step 171). This specified page is shown in FIG.
Is stored in the delivery information buffer for the processing instruction as the determination result (page identification information) performed in step 141 of FIG. If the page is currently being displayed, it is determined whether there is a page older than the designated page by referring to the access date and time in the access history table 16 (step 172). If there is, an existing page display instruction for an old page immediately before the designated page is created for internal processing (step 173). This internal existing page display command is a temporary one used only in the existing page deletion processing.

If there is no page older than the designated page, an existing page display instruction for a new page immediately after the designated page is created for internal processing (step 174). It should be noted that the record existing in the access history table 16 is only the access history information corresponding to the currently displayed page, and if there is no page before and after the designated page, it is guarded that the delete item cannot be selected from the menu. As a matter of fact, the processing here does not consider such a case.

On the other hand, if the specified page is not currently being displayed, an image of information is currently displayed, that is, an information image is created in the content display section, and an existing page display instruction for the page displayed on the display device 2 is internally stored. It is created for processing (step 175). The page identification information of the page specified in each of the steps 173 to 175 is stored in the processing information delivery information buffer for the subsequent existing page display processing.

Next, the processing execution unit 14 deletes the access history information of the page specified as the deletion target from the access history table 16 (step 176). Thereafter, an internal processing command is issued to perform an existing page display process (step 177). The existing page display processing is executed by performing the above-described processing shown in FIG. 11 with reference to the page identification information stored in the delivery information buffer for the processing instruction. For the existing page display process here,
Description is omitted.

The above processing will be described with reference to the display example shown in FIG. For example, if the user wants to delete the page "TV" while the page "Product Introduction" is displayed as shown in FIG. 5E, the user clicks the right mouse button on the label of "TV" with the mouse. The menu 17 is displayed as shown in FIG. Here, when the item to be deleted in the menu 17 is selected, the result of internally executing the existing page display processing for displaying the information of the old page “Product introduction” immediately before the page “TV” to be deleted is displayed. 5 (g) will be displayed.

As described above, according to the present embodiment, when a page is deleted, the page is extracted from the document, the extracted location is filled with a new page, and the document is composed of the remaining pages. It can be re-displayed as if it were. In this way, even when a page is deleted, it is possible to display the image as if a bundle of documents was created on the remaining pages where the page was removed,
An intuitive user interface can be provided.

In the above-described embodiment, the communication with the WWW server is performed every time information is displayed on the content display unit, and the latest information can be always displayed by acquiring the information. If the importance is placed on the page, information when a new page is displayed may be stored in the inside. The storage location information in this case includes
