The operation of the information processing apparatus shown in FIG. 1 will be described below.

FIG. 3 is a flow chart for explaining the overall operation of the information processing apparatus shown in FIG.

First, the Web browser 2 reads a home page based on the URL designated by the user (step 301).

Next, the display / abbreviation information generator 4 displays / displays
The omitted information storage unit 5 is searched, and the display / omitted information for the home page read by the Web browser 2 is selected (step 302).

Next, the display / omission information generation unit 4 uses the display / omission information selected in step 302 to generate new display / omission information for the home page read by the Web browser 2 and displays the display / omission information. The data is stored in the storage unit 5. The output information generation unit 8 generates the display output information based on the output set value read from the output set value storage unit 7 and the display / omitted information read from the display / omitted information storage unit 5, and at the same time outputs the output setting. If the value is set to read aloud, voice output information is generated. Then, the display output unit 9 magnifies and outputs the display output information generated by the output information generation unit 8, and the audio output unit 10
If the output setting value is set to read aloud, the audio output information generated by the output information generation unit 8 is read aloud and output (step 303).

Next, the user selects an operation (step 304).

For example, when the user selects an operation for changing the output setting at the time of enlarged display / speech, the output setting value switching unit 6 switches the setting of various parameters as shown in FIG. The value is stored in the output set value storage unit 7 (step 305).

Further, when the user selects an operation for designating a display / omission part on the home page, the target range acquisition unit 3 acquires the display / omission target range from the HTML source of the home page and displays it. / The omission information generation unit 4 generates new display / omission information in which display / omission is designated for the target range acquired by the target range acquisition unit 3 (step 306).

When the user selects the operation of moving the home page, the Web browser 2 reads the home page based on the URL of the home page of the moving destination (step 307).

In the following, steps 302 and 3 shown in FIG.
Each processing of 03 and 306 will be described in detail.

First, the processing of step 302 shown in FIG. 3 will be described in detail with reference to the flowchart of FIG.

First, the display / abbreviation information generation unit 4 uses the Web
Based on the URL of the homepage read by the browser 2, the homepage with the same URL or the UR of the same site
The display / abbreviated information matching the home page having L is searched from the display / abbreviated information storage unit 5 (step 401).

Here, if there is no display / abbreviation information that matches the homepage corresponding to the search target in step 401 (“none” in step 402), the display / abbreviation information generation unit 4 reads the homepage read by the Web browser 2. A default value is selected as display / abbreviation information for (step 403). The default value of the display / omission information is set, for example, to specify the display for all the HTML sources of the home page.

On the other hand, if there is display / omission information that matches the home page corresponding to the search target in step 401 (“Yes” in step 402), the display / omission information generation unit 4 displays the corresponding home page and the Web browser 2. It is determined whether the structures of the read homepages match (step 404).

Here, when the structures of both homepages do not match (“mismatch” in step 405), the display / omission information generation unit 4 defaults as display / omission information for the homepage read by the Web browser 2 in step 403. Select a value.

On the other hand, if the structures of both homepages match (“match” in step 405), the display / omission information generation unit 4 determines that the homepages have the structure as the display / omission information for the homepage read by the Web browser 2. Display / omit information for the matching homepage is selected (step 406).

It should be noted that in FIG. 4, the user himself selects W
It is also possible to select display / abbreviation information for the home page read by the eb browser 2. In that case, display /
Before the processing of step 401, the omission information generation unit 4 determines whether or not there is an instruction to select display / omission information by the user. If there is an instruction from the user, the display / omit information instructed by the user is selected, and if there is no instruction from the user, the process proceeds to step 401.

Here, steps 404 and 4 shown in FIG.
The process of 05 will be described in detail with reference to the flowchart of FIG.

First, the display / omission information generation unit 4 compares tags such as <Frame> and <Table> that determine the layout of both homepages, and determines whether the order, number, parameters, etc. of these tags match. Confirm (step 501).

Next, the display / abbreviation information generation unit 4 compares tags such as <P> and <Div>, the number of which changes depending on the content of the text, and confirms whether these tags match (step 502). In this case, the same tags such as <P> and <Div> may be present on both websites, and the number of tags may be different.

Next, the display / abbreviation information generator 4 compares the texts in the same tag and confirms whether the same text is included in the same tag (step 503).

After that, the display / omission information generation unit 4 determines whether the structures of both homepages match based on the comparison result of steps 501 to 503 (step 50).
4). In this case, the priority of the comparison result of step 501 is set to be the highest, and the comparison result of step 502 and the comparison result of step 503 are reduced in order in this order, and determination is performed.
For example, if the comparison results in step 501 match or if the comparison results in steps 501 and 502 match, it is determined that the structures of both homepages match.

The structure of both homepages is <Frame>
If it is divided into multiple frames by tags such as, the comparison is performed for each frame.

Further, in step 401 shown in FIG. 4, when display / abbreviation information for a plurality of homepages is retrieved, a comparison is made for each of the plurality of homepages, and the homepage having the most matching portion is selected. select.

Next, the processing of step 303 shown in FIG. 3 will be described in detail with reference to the flowchart of FIG.

First, the display / omission information generation unit 4 reads the selected display / omission information for the home page read by the Web browser 2 from the display / omission information storage unit 5 in step 302 shown in FIG. Homepage HT
The part of the ML source for which display / omission is designated is confirmed (step 601).

Next, the display / omission information generation unit 4 confirms, among the parts designated to be omitted, the part whose contents have been updated since the previous reading (step 602). The information of the part obtained by this process is shown in the output set value in FIG.
When the difference notification designation shown in is set, the information is used for the difference notification designation processing in the output information generation unit 8.

Next, the display / abbreviation information generation unit 4 confirms, among the portions which are not designated to be displayed, the portions whose contents have not been updated since the last reading (step 60).
3). The information of the part obtained by this process becomes the information used for the process of the automatic omission specification in the output information generation unit 8 when the automatic omission specification shown in FIG. 2 is set in the output setting value.

Next, the display / omission information generation unit 4 uses the Web
For the home page read by the browser 2, the display / omit designation confirmed in step 601 is performed, and the parts confirmed in steps 602 and 603 are integrated to generate new display / omit information (step 604), and display / omit information is displayed. The data is stored in the omitted information storage unit 5 (step 605).

Next, the output information generation unit 8 reads the display / omission information for the home page read by the Web browser 2 from the display / omission information storage unit 5, and the current output setting value from the output setting value storage unit 7. It is read (step 606).

Next, the output information generation unit 8 generates the display output information based on the display / omission information and the output set value, and if it is set that the output set value is read aloud, a voice message is output. Generate output information (step 6)
07).

At this time, the information of the part whose contents have been updated since the previous reading in the omitted parts and the contents which have been updated since the previous reading in the parts which are not designated to be displayed have been updated. The information of the missing portion is reflected in the display / omission information by the processing of steps 602, 603, and 604.

Therefore, when the output setting value is set to the difference notification designation or the automatic omission designation, the output information generation unit 8 uses the information reflected in the display / omission information to designate the difference notification designation. And automatic omission specification processing are performed to generate display output information and audio output information.

Thereafter, the display output unit 9 enlarges and outputs the display output information generated by the output information generation unit 8 and outputs it, and the voice output unit 10 is set to read the output set value. In this case, the voice output information generated by the output information generation unit 8 is read out and output (step 60).
8).

The display / omission information generation unit 4 uses the Web
If the home page read by the browser 2 is the first one to be read, it is not necessary to perform the processing of steps 602 and 603.

Next, the processing of step 306 shown in FIG. 3 will be described in detail with reference to the flowchart of FIG.

First, the user designates a part of a character string including a portion to be displayed or a portion to be omitted as target range designation information (step 701).

Next, the target range acquisition unit 3 extracts HTML tags in a predetermined range including a part of the character string designated by the user (step 702).

Next, the user designates the tag corresponding to the display / omission target range among the tags extracted in step 702 as the target range switching information, and the target range acquisition unit 3
Adjusts the display / omission target range based on the target range switching information, and acquires the target range from the Web browser 2 (step 703).

At this time, the user specifies, as the tag corresponding to the display / omission target range, only a tag surrounding a part of the character string specified by the user, or a tag specified by the user himself. Specify the tag that includes one or both of the preceding and following sibling tags of the sibling tags such as <P> and <Div> that are in the same row as the tag that encloses the character string of the part, or you can specify it yourself. Specify a tag that includes a parent tag such as <Frame>, <Table>, etc. of the part that encloses part of the specified character string.

When the target range switching information is specified by the user, the target range acquiring section 3 adjusts the display / omission target range based on the target range switching information.
Normally, the tag is selected by itself based on the information defined by default, and the display / omission target range is adjusted.

Next, the user displays / displays the portion for displaying / omiting the target range acquired by the target range acquiring unit 3.
It is designated as omission designation information (step 704).

After that, the display / omission information generation section 4 generates new display / omission information based on the display / omission specification information specified by the user and stores it in the display / omission information storage section 5 (step 705). .

Specifically, as shown in FIG. 8 (a), when the user specifies a part of the character string "Is it raining tomorrow?" In paragraph B in the HTML source, the target range As illustrated in FIG. 8B, the acquisition unit 3 includes an HTM in a predetermined range including at least a paragraph B surrounding a character string designated by the user.
Extract the L tag.

Here, if the user specifies only the tag of paragraph B as the tag corresponding to the display / omission target range, the target range acquisition unit 3 displays the display / including the paragraph B tag.
The omission target range is acquired from the Web browser 2.

When the user designates a tag including one or both tags of the preceding and following paragraphs A and C which are in the same row as the tag of paragraph B as the tag corresponding to the display / omission target range. The target range acquisition unit 3 sets the target range of display / omission including the tags of one or both of the paragraphs A and C to W.
Obtain from eb browser 2. In this case, the range in which the tags are extracted when the user specifies a part of the character string of the paragraph B includes not only the tag of the paragraph B but also one or both of the tags of the paragraphs A and C. It becomes a range.

When the user specifies a tag including the parent tag of the paragraph B tag as the tag corresponding to the display / omission target range, the target range acquisition unit 3 determines the parent tag of the paragraph B tag. The target range of display / omission including is acquired from the Web browser 2. In this case, the range in which the tag is extracted when the user specifies a part of the character string of the paragraph B is not only the tag of the paragraph B but also the range of the parent tag of the paragraph B.

As shown in FIG. 9A, when the home page is composed of frames 1, 2, and 3, the display / omission information includes information on the HTML source of each of the frames 1, 2, and 3, And HTML of each frame 1, 2, 3
It is necessary to make the source retain the information of the part specified to be displayed / omited.

Each frame 1, 2, 3 is added to the display / abbreviation information.
When the information of the portion for which display / omission is designated is held in the HTML source of, the display / omission in the HTML source of each frame 1, 2 and 3 is designated as shown in FIG. 9B. Part of the special tag <display / omit
The HTML source may be held in a state where the display> and the <omission> are embedded. Further, the information of the portion for which display / omission is designated may be held as a file separate from the HTML source.

The overall operation of the information processing apparatus shown in FIG. 1 will be described below with reference to specific examples. here,
As shown in FIG. 10, it is assumed that there is a homepage A and a homepage B having the same structure as homepage A (homepage having the same URL as homepage A or a homepage having the same site URL as homepage A).

As described above, in the present invention,
Since the display enlargement range is specified by using the control information of the document, even a user who cannot properly specify the display enlargement range with a mouse or the like can easily specify the target display enlargement range.

As described above, since the display enlargement range is not designated by the actual screen image but the display enlargement range is logically designated by using the tag information, the display enlargement range should be surely enlarged. You can Further, since it is possible to easily specify the display enlargement range even for a document including a lot of information such as a homepage HTML document, the desired information on the homepage can be easily enlarged and displayed. .

Further, since the control range of the document is used to specify the omission range together with the display expansion range of the document, the omission range of the document can be easily specified.

For example, when the control information of the document is tag information, a part of the character string within the display enlarged range or the omitted range of the document is designated, and further extracted from the predetermined range including the part of the character string. Specify the tag that corresponds to the display expansion range or the omitted range. Therefore, it is possible to structurally take out the information of the display enlargement range including the specified part of the character string and enlarge and display it.

Information on the display enlargement range or the omission range designated for the document is held as display / omission information, and an output set value for outputting the display enlargement range by enlarging display or reading is held. Since the display enlarged range is output by magnifying and reading out based on the display / omission information and the output setting value, various output settings can be performed by utilizing the display / omission information and the output setting value.

For example, when it is desired to obtain information on the display enlarged range as if listening to a radio, the output set value may be set to continuously read out the portion of the display enlarged range. Further, when it is desired to redisplay the omitted range, that effect may be set in the output setting value.

When the display / omission information for the first document is already stored, the display / omission information for the second document having the same structure as the first document is displayed / omitted for the first document. Since the information is generated by using the information, it is possible to output the second document by enlarging display or reading aloud, after the display / omission designation is performed similarly to the first document.
