Abstract

PROBLEM TO BE SOLVED: To display in a browser a page that is easy to read in conjunction with text reading by providing a reading processing function for a web page.SOLUTION: A browser 1 determines whether lateral scrolling has occurred during normal display of a page. If lateral scroll has occurred, the browser reduces the lateral width of a display component on the displayed page to be equal to or less than the width of a region of a display screen, and further reconfigures the layout so that the display component fits within a display region. Then, the browser 1 displays the reconfigured page.

Description

  The present invention relates to a browser for browsing data described in a markup language such as HTML (HyperText Markup Language) data. The related invention is a browser program with a reading function and a browser with a reading function (browsing device) for performing browser processing of HTML data having a reading function for synthesizing and outputting text data in the displayed HTML data. The present invention relates to a browsing processing method and a browser program recording medium.

As one of the data processing functions of a computer, there is a text-to-speech function for synthesizing and outputting an electronic document (text data) or the like. With the text-to-speech function, the user can grasp the contents by listening to the sound output from the speaker instead of viewing the document output by the display device or the printing device.
For data such as web pages (web pages) on the Internet, an HTML data browsing device (browser) normally displays web page content in a predetermined display area. The text data in the page can be output as voice.

  In the reading-out function, processing is performed in which the text before and after the read-out part is clearly displayed in conjunction with the voice output of the reading-out so that the user can check which part of the text is being read out. On the other hand, when the display size of the web page exceeds the content display area size of the browser, the browser displays a part that fits in the display area size and switches the display part by the scroll function.

  Since general web pages are created assuming a relatively large screen such as a display device of a personal computer, display screens such as car navigation systems, mobile phones, and portable information terminals such as PDAs (Personal Digital Assistants) When browsing a general web page with a small device, scrolling up, down, left, and right is forced. Therefore, when a web page is read out in an apparatus in which the display screen size is restricted, the browser frequently performs left and right (horizontal) scrolling in order to display, for example, a reading portion of horizontal text.

  FIG. 18 is a diagram for explaining a problem when a general HTML data 90 is scrolled and read out by a browser having a small content display area 91 for displaying a web page. As shown in the upper part of FIG. 18, if the display size of the HTML data 90 of the web page exceeds the width of the content display area 91 and the browser does not display the reading portion 92 in the content display area 91, In order to display the reading portion 92 in accordance with the output, the web page is scrolled horizontally, and the display portion of the web page is changed so that the corresponding reading portion 92 falls within the content display area 91 as shown in the lower part of FIG. Switch. Further, when the reading is advanced and the corresponding reading portion 92 is moved, the display portion of the web page is similarly switched and the reading portion 92 is displayed in the content display area 91. For the user, frequent switching of the display can be annoying.

  Conventionally, in order to be able to display a web page without causing horizontal scrolling due to the display of the reading portion, the following measures have been taken.

  1) The content provider provides read-only HTML data in consideration of the display size of the content to be read so that the web page can be displayed without scrolling horizontally on the display screen of a predetermined device. When reading aloud, a web page dedicated to reading was displayed.

  2) Adapted to reading based on HTML tags specified by the user (for example, <B> </ B>, <I> </ I>, etc.) or special tags defined in advance on the browser side The HTML data is reconstructed to be displayed.

  For example, in the technique of Patent Document 1 shown below, a special tag for reconstruction is set in advance in a user profile describing a display form according to the user's preference, and the browser uses the acquired HMTL data as the user profile. Reconfigure and display as described. By setting a special tag for reading in the user profile, display adapted to reading can be performed.

  Further, in the reading function, all text data to be read out is synthesized by speech and output. However, if all text data that is supposed to be output in character display is output as speech, parentheses and special symbols in the text data may sound annoying because it hinders the natural flow of speech and may hinder understanding of the content.

  Therefore, for example, as in the technique of Patent Document 2 shown below, parentheses and special symbols that do not need to be read out by speech synthesis processing are set in advance, skipping the set symbols in the text data, and only characters There is a processing method to read out.

JP 2003-223463 A JP 11-338673 A

  There are many users who want to obtain information from the website even when the displayed content cannot be watched. There is a high demand for browsers that can be easily confirmed on the display screen.

  However, when a web page that causes horizontal scrolling is read out in a browser with a small display screen, switching of the screen for displaying the read portion becomes more frequent. It is a heavy burden on the content provider to prepare in advance another HTML data dedicated to reading in accordance with the content display area of the browser.

  Also, as in the technique of Patent Document 1, HTML data to which a special tag for reconstruction is added and a user profile describing a display form using the special tag are prepared, and the browser reconfigures the web page so that it is adapted for reading aloud. Is displayed, the reconfigured web page does not retain the configuration of the original web page. Furthermore, since only specific information is extracted from the original web page at the time of reconfiguration, there is a possibility that information is lost and the original information cannot be provided.

  On the other hand, general web pages include many information that is not related to the original content such as link instructions to other pages and advertisement banners, and information that is repeatedly displayed on multiple pages such as company name and copyright notice. include. It is redundant to read out information other than the information that the content provider originally wants to provide, which causes confusion for the user.

  It is an object of the present invention to provide a reading function for synthesizing text data in a web page and outputting it as a voice, and without using a dedicated HTML data for reading, so that no troublesome screen switching and content loss occur. A browser program with a reading function, a browser with a reading function, a browsing processing method, and a browser program recording medium for displaying a web page with a layout adapted to the above.

  Another object of the present invention is to provide a browser with a reading function, which has a reading function for synthesizing text data in a web page and outputting the voice, and can read only the content originally intended to be read from the reading-target web page. A program, a browser with a reading function, a browsing processing method, and a browser program recording medium are provided.

  According to the display program of the present invention, a display component based on data described in a markup language includes a text component and a non-text component on a computer, and at least one of the text component and the non-text component is displayed on a display screen. If the part exceeding the horizontal display width is a non-text part when the horizontal display width is exceeded, the non-text part is reduced so as not to exceed the horizontal display width of the display screen. A process for generating a non-text part and displaying it together with the text part is executed.

  The browser with a reading function, which is a related invention of the present invention, has a reading processing means for synthesizing text data and outputting it as voice data, converting HTML data into display data and displaying it in a predetermined display area. In a browser with a reading function that reads out the text data in response to a user request, it is determined whether or not display data to be displayed in the display area is displayed in a state in which it can be scrolled in the horizontal direction. The horizontal width of each display component of the display data is equal to or smaller than the horizontal width value of the display area when the horizontal scroll determination processing means is displayed and the display data is displayed in a state where horizontal scrolling is possible. Optimized layout processing for reconfiguring the layout so that the size is changed so that the changed display component fits in the display area And display data reconstructed by the optimized layout processing means is displayed in the display area in a state in which it can be scrolled in the vertical direction, and the display data read out by the read-out processing means is read out. Scroll processing means for displaying the part in the display area in a display mode different from the part other than the read-out part.

  According to the present invention, when HTML data such as an Internet web page is converted into display data and displayed in a predetermined display area by the horizontal scroll determination processing means, the display data displayed in the display area is displayed in the horizontal direction. It is determined whether or not the screen is displayed in a state where scrolling is possible.

  When the display data is displayed in a state in which scrolling in the horizontal direction is possible, the width of each display component of the display data is equal to or less than the width value of the display area by the optimized layout processing means. And the layout is reconfigured so that the changed display component fits in the display area. Specifically, the width value of each display component of the display data is obtained, and the width value of the text display component that displays text data among the display components is changed to be equal to or less than the width value of the display area, and the text display The display components other than the components are reduced to fit in the display area, and the layout of the display components is reconfigured so that the display data can be displayed without scrolling in the horizontal direction.

  The display data reconstructed by the optimized layout processing means is displayed in the display area in a state where scrolling in the vertical direction is possible by the scroll processing means, and the display is output by voice by the reading processing means. The read-out portion of the data is displayed in the display area in a display mode different from the portions other than the read-out portion.

  Thus, when the browser of the present invention displays a web page acquired from the Internet on a predetermined small screen and starts reading out the text content of the web page, the browser does not scroll horizontally on the small screen. The display component is reconfigured so that the web page can be displayed, and the reconfigured web page is displayed in the display area. Then, the text content of the web page is displayed in a display mode in which the read-out portion that is output is conspicuous in accordance with the text content that is output by the speech processing means.

  The browser with a reading function of the present invention includes a reading processing means for synthesizing text data and outputting it as voice data, converting the HTML data into display data and displaying it in a predetermined display area, In a browser with a reading function that reads out the text data in response to a request, 1) means for storing specific symbol information indicating a range of text data not to be output by the reading processing means, and 2) the HTML data Text data to be read out by the reading processing means, and based on the specific symbol information, text data surrounded by a specific start symbol indicating a start position and an end position indicating the end position of the range from the text data. Extraction range determination processing to extract and delete the extracted text data And a stage.

  In addition, the present invention provides, for example, specific symbol information in which a combination of a specific start symbol indicating a start position of a range of text data not to be output by the reading processing unit and a specific end symbol indicating the end position of the range is set. Means for storing. The specific symbol information is a symbol or character that can be specified by a character code, for example, “[” and “]”, “*” and “*”, “*” and “*”, “#” and “”. ” A combination of these may be used. Also, it may be a combination of a plurality of characters or symbols such as “**” and “**”, “**” and “*”.

  When the text content displayed on the small screen is read out, the skipping range determination processing means of the browser acquires the text data read out by the reading processing means from the HTML data, and based on the specific symbol information. The text data surrounded by the specific start symbol and the specific end symbol combined from the text data is extracted and deleted from the text data for the reading process.

  As a result, the present invention skips information such as cautions and copyright notices that are unrelated to the information provided as the original content from the text content to be read out, using preset specific symbol information. Can do. As a result, the user can efficiently listen to information that the content provider originally wants to provide.

  The present invention provides a data processing device having a display screen smaller than the display size of a general web page, such as a car navigation device, a portable small information terminal such as a mobile phone with a data communication function or a PDA, an information home appliance (for example, It can be used for browsers installed in data processing devices built into the system kitchen. These data processing devices are highly likely to be used in situations where content displayed on the display screen cannot be watched, such as during driving or working.

  According to the present invention, a web page is displayed in accordance with a small display screen without being horizontally scrolled around a read-out portion that is output as a sound, as the content is output as a sound. This can prevent frequent screen switching when displaying a read-out portion on a display screen having a size restriction. When the user wants to acquire information from the web page during driving or working by reading out in conjunction with the display of such content, the user can easily confirm the reading-out location while listening to the content.

  Further, according to the present invention, it is not necessary to create read-only HTML data for a device having a small display screen, and content of a general web page for a personal computer can be read out. Thereby, the content creation burden of the content provider can be reduced.

  Further, according to the present invention, it is possible to perform display linked to reading without losing information of the original web page. Thereby, the user can browse a general web page for a personal computer even with a device having a small display screen.

  Further, according to the present invention, it is possible to output information by skipping information unrelated to the information provided as the original content. Thereby, the user can efficiently collect useful information on the web page.

[Optimized layout processing]
Hereinafter, the optimized layout process will be described in more detail. The content to be processed is HTML data shown in FIG. 2, and the screen width of the content display area of the browser 1 is 240 pixels.

  Under the control of the browsing processing control unit 110, HTML data acquired from a server of a certain website is expanded into a widget tree shown in FIG. 4, and a web page as shown in FIG. 6A is displayed in the content display area. Is displayed. Since the screen width of the content display area is 240 pixels and it is not possible to display all the contents at the same time, the image display processing unit 115 displays the contents in a display state that allows horizontal scrolling in the content display area. Note that a series of these processes is a general browsing process, and a description thereof will be omitted.

  When a web page is displayed in such a state and a user requests a reading process, the horizontal scroll determination processing unit 121 determines that the display is in a state in which horizontal scrolling is possible, and an optimized layout process is performed. The determination result is passed to the unit 122.

  The optimized layout processing unit 122 determines the arrangement coordinates of the widgets W1 to W7 in order to display the widget tree of FIG. 4 generated by the layout processing unit 113 in the content display area. According to the hierarchical structure of the widget tree, the content display area is arranged from the upper left in order from the upper widget, and the size (size) so that each widget fits within the width of the window widget W1 (hereinafter, screen width) = 240 pixels. Change the position. FIG. 5 shows an arrangement example of widgets based on the widget tree of FIG.

  First, since the width of the image widget W2 is larger than the screen width, the image widget W2 is reduced in size to fit within the screen width in a shape that maintains the aspect ratio of the image.

  Next, since the size of the table widget W3 is not specified, the table widget W3 is determined after obtaining the minimum sizes of the cell widgets W4 and W5. First, in order to determine the size of the cell widget W4, the size of the content widget is obtained. Since the size of the image widget W6, which is the contents of the cell widget W4, is large enough to fit within the screen width, the image is not reduced. Therefore, the size of the cell widget W4 is determined.

  Next, in order to determine the size of the cell widget W5, the size of the content widget is similarly obtained. The character string of the text widget W7 is designated as NOBR (line feed prohibition), but it does not fit in the screen width unless the character string is folded, so the NOBR designation is invalidated and the size of the minimum cell widget is the size of one character. To decide.

  When the sizes of the cell widgets W4 and W5 are determined, the size of the table widget W3 is determined. However, since the determined size of the table widget W3 is larger than the screen width and the two widgets of the cell widgets W4 and W5 cannot be arranged side by side, as shown in FIG. The cell is divided so as to be arranged under the widget W4. Then, each cell widget is laid out according to the determined arrangement position of the cell widgets W4 and W5.

  FIG. 7 shows a display example when the processing of the present invention is applied to the HTML data 90 shown in FIG. According to the present invention, since the display processing is performed so that the width of the web page developed from the HTML data 90 falls within the screen width of the content display area, horizontal scrolling does not occur. Therefore, when displaying the read-out part during the read-out process, the screen is switched only by vertical scrolling, and frequent screen switching does not occur. Therefore, the user can easily check the read-out part.

  8 to 12 show the processing flow of the present invention.

  FIG. 8 shows an outline processing flow of the present invention.

  This process is started when there is a request for a reading process during the display process of HTML data under the control of the browsing process control unit 110. The horizontal scroll determination processing unit 121 determines whether horizontal scrolling has occurred (step S1). If it is determined that horizontal scrolling has occurred, an optimized layout process is performed (step S2), and a reading process is performed (step S3). On the other hand, when it is determined that the horizontal scroll has not occurred, the reading process is performed as it is (step S3).

  FIG. 9 shows the process flow of the optimization process.

  The optimized layout processing unit 122 sequentially acquires widgets to be subjected to layout processing from the widget tree (step S21). If there is a widget to be laid out (step S22), it is determined whether or not the widget is a text widget (step S23). If it is a text widget, text processing is performed (step S24). If it is not a text widget, it is determined whether it is an image widget or a form widget (step S25).

  If the widget is an image widget or a form widget (Textarea, pushButton, etc.), the image and form are processed (step S26), and if it is not an image widget or a form widget, it is determined whether it is a table widget. (Step S27). If the widget is a table widget, the table is processed (step S28). If not, the process returns to step S21.

  If there is no widget for layout in the process of step S22, the process ends.

  FIG. 10 shows a detailed processing flow of step S24 shown in FIG.

  If the tag <BR> is continuous in the text widget, the optimized layout processing unit 122 processes the tag <BR> as one (step S241). Then, it is determined whether or not there is a non-layout character string in the text (step S242). If there is a non-layout character string, the non-layout character string is divided by the screen width (step S243). It should be noted that the specification of loopback suppression (<nowrap> <nobr> etc.) is invalid.

  Further, it is determined whether or not the prohibited character string (English words, numerical values, punctuation marks, parentheses, etc.) is divided (step S244). If the prohibited character string is divided, further arrangement is performed. It is determined whether or not the position is at the beginning of a line (step S245). If the arrangement position is not the beginning of the line, the divided prohibited character string is driven backward (step S246). On the other hand, if the arrangement position is the beginning of the line, it is left as it is. On the other hand, if the division prohibited character string is not divided, the divided character string is placed (step S247).

  In step S242, if there is no unlayed character string in the text, the process ends.

  FIG. 11 shows a detailed processing flow of step S26 shown in FIG.

  The optimized layout processing unit 122 determines whether the image widget or the form widget fits in the screen width (step S261). If the image widget or form widget does not fit in the screen width, the image or form is reduced to the screen width regardless of whether the width value (width) and height value (height) are specified. The height of the image is reduced at the same reduction ratio as the width (step S262). On the other hand, if the image widget or form widget fits within the screen width, the process proceeds to step S263.

  Then, an image or a form is arranged (step S263).

  FIG. 12 shows a detailed processing flow of step S28 shown in FIG.

  The optimized layout processing unit 122 performs table and cell analysis processing, and acquires the maximum width value and the minimum width value in the cell (step S281). It is determined whether or not the table fits in the screen width (step S282). If the table does not fit in the screen width, the cells are blocked based on the line where the underline is aligned in all the columns of the table, and the order is determined (step S283). Then, it is determined whether or not there is an unprocessed cell block (step S284). If there is an unprocessed cell block, processing such as adjustment of the cell width and sending to the next row is performed on one unprocessed cell block having a high priority so as to fit within the screen width. The height is aligned with the maximum height of each cell widget content (step S285). Then, the process returns to step S284.

  On the other hand, if the table fits in the screen width in step S282, or if there is no unprocessed cell block in the process of step S284, the process proceeds to step S286.

  In step S286, a table is arranged and the process ends.

  FIG. 13 shows a detailed processing flow of step S3 shown in FIG.

  The reading text acquisition processing unit 123 determines whether there is a text to be read in the DOM tree (step S31). If there is a reading target, the text is acquired from the DOM tree (step S32), and a widget corresponding to the text to be read is obtained (step S33).

  Then, it is determined whether or not the top of the widget is within the display area (step S34). If the head of the widget is not within the display area, the text is vertically scrolled so that the head of the text to be read is within the display area (step S35), and the character string color of the part to be read is changed and highlighted (step S36). Furthermore, the speech synthesis processing unit 131, the waveform generation processing unit 132, and the speech output processing unit 131 convert the character string in the reading portion into speech data and read it out (step S37). Thereafter, the process returns to step S31.

On the other hand, if the top of the widget is within the display area, the process proceeds to step S36.
[Skip range judgment process]
In the following, a process for determining a portion that does not need to be output as audio when reading out content will be described.

  FIG. 14 shows a display example of a web page of a general news providing site. Among the contents of the web page shown in FIG. 14, the information that the content provider wants to provide is the news itself. For the user, the title display part C1 for displaying the news classification and the text display part C2 for displaying the news text are necessary for reading, and the supplementary information display part C3 for displaying supplementary information and copyright display is unnecessary. It is.

  Therefore, a symbol that is easily used for supplementary information or the like is set in advance as specific symbol information and stored in the specific symbol information storage unit 126. The specific symbol information may be a combination of a specific start symbol indicating the start position of the range to be skipped and a specific end symbol indicating the end position of the range to be skipped.

  The skipping determination processing unit 127 refers to the specific symbol information storage unit 126, analyzes the character code of the text data acquired by the reading text acquisition processing unit 123 and stored in the temporary reading text buffer, and starts specifying If a symbol is searched for and there is a specific start symbol in the text data, a corresponding specific end symbol is further searched. Then, the character string surrounded by the specific start symbol and the specific end symbol is deleted from the text data to be read out.

  For example, a combination of “*” and “*”, “*” and “. (Period)”, “*” and “. (Reading mark)”, etc. is set as specific symbol information. The skip-reading determination processing unit 127 receives the character code set as the specific symbol information from the text data of the title display part C1, the body display part C2, and the supplementary information display part C3 of FIG. 14 acquired by the read-out text acquisition processing part 123. Search for. Since the first character of the text of the supplementary information display portion C3 is “*” and the last character is “. (Period)”, the character string of the text of the supplementary information display portion C3 is deleted from the text to be read out. The Therefore, text data in which the supplementary information display part C3 is deleted from the text of the web page displayed as shown in FIG. 14 is stored in the reading text buffer. Then, the contents of the title display portion C1 and the body display portion C2, which are text data in the read-out text buffer, are converted into speech through the processing of the speech synthesis processing unit 131, the waveform generation processing unit 132, and the speech output processing unit 133. Output from the speaker 3.

  Further, FIG. 15 shows a display example of a web page of another general news providing site. The web page in FIG. 15 has a style in which each news body page is displayed from each news headline C21, C22, C23,. In this case, it is assumed that the supplementary information display portion C3 of the first page is also displayed on each news text page. In the conventional reading process, the contents of the supplemental information display portion C3 are read out each time each page is read out.

  However, similar to the above-described processing, the skip-through range determination processing unit 127 detects the specific symbols of the first character “*” and the last character “. (Reading mark)” of the text data of the supplementary information display portion C3, and The part surrounded by these specific symbols is read and deleted from the text data in the text buffer. Therefore, the user can hear only useful news texts.

  16 and 17 show the processing flow of the present invention.

  FIG. 16 shows a detailed processing flow of the skipping range determination processing.

  The skipping range determination processing unit 127 reads text data from the read text buffer (step S41). A specific start symbol is searched from the text data (step S42). When the specific start symbol is hit (step S43), the specific end symbol is searched from the text data (step S44). When the specific end symbol is hit (step S45), the character string between the specific start symbol and the specific end symbol in the text data is deleted (step S46), and the deleted text data is written into the read-out text buffer. Return (step S47).

  On the other hand, if the specific start symbol is not hit in the process of step S43, the process of step S47 is performed.

  FIG. 17 shows a detailed flow of the reading-out display process in step S3 when the skip-out range determination process is performed.

  The processing in steps S51 to S57 in the processing flow illustrated in FIG. 17 corresponds to the processing in steps S31 to S37 in the processing flow illustrated in FIG. In the reading-out display process in the case of performing the skipping range determination process, the point that the process of step S58 is performed is different between the processes of step S52 and step S53.

  In the process of step S58, it is determined whether or not there is a character string to be read out in the text after the skip-out range determination process (read-out process). If there is a character string to be read, the process proceeds to step S53. If there is no character string to be read, the process returns to step S51.

  As mentioned above, although this invention was demonstrated by the embodiment, it cannot be overemphasized that various deformation | transformation are possible for this invention in the range of the main point.

  Further, the present invention can be implemented as a processing program that is read and executed by a computer. The processing program for realizing the present invention can be stored in an appropriate recording medium such as a portable medium memory, a semiconductor memory, and a hard disk that can be read by a computer. It is provided by transmission / reception using various communication networks via a communication interface.

  The present invention provides a data processing device having a display screen smaller than the display size of a general web page, such as a car navigation device, a portable small information terminal such as a mobile phone with a data communication function or a PDA, an information home appliance (for example, It can be used for browsers installed in data processing devices built into the system kitchen. These data processing devices are highly likely to be used in situations where the content displayed on the display screen cannot be watched, and there is a high demand for a web page reading function that makes it easy to check the reading position.
