Description

  The present invention relates to a web content display device, an operation method of the web content display device, and a computer program.

  With the spread of the Internet, various information can be obtained through the web. Therefore, there is a need for a website that can be accessed by many people, including the elderly and people with disabilities. In other words, the design of a website that can access the website, that is, web accessibility is required.

  However, since many web pages including portal sites contain too much information, there is a problem that it is difficult to grasp the outline of the web page. This is another accessibility issue. The headline is effective in understanding the outline of the web page. In HTML, a heading element is defined, and by marking up that it is a heading, the browser displays the heading separately from other elements such as bold or large font, so if you browse only the heading, You can get an overview of the web page.

  Web pages are used not only on PCs but also on mobile phones. In recent years, smart phones have become widespread and it has become possible to browse web contents. However, since it may be difficult to browse on a small screen of a mobile phone or a smart phone, there are increasing cases of preparing web contents for a mobile phone or a smart phone.

  Web accessibility has been formulated into guidelines such as JIS X 8341-3, and various consideration methods are summarized. An evaluation tool according to such guidelines has also been developed (see Patent Document 1).

  In mobile terminals such as mobile phones, smart phones and tablet terminals, the display area of the page is limited, and therefore, a web page having a unique layout may be prepared separately from the web page for PC. Since the display area of the portable terminal is small, if the information is packed, the characters become small and the page is difficult to see.

  Therefore, there are many cases where pages with a reduced amount of information are created for mobile terminals. For example, a web page for a smart phone generally has a page design in which only a vertical scroll operation is performed without performing a horizontal scroll operation because providing a horizontal scroll makes it difficult to understand the displayed position. For this reason, when information increases, a vertically long page is created, and many scrolling operations are required before reaching the information to be viewed, resulting in a problem that the information to be viewed cannot be searched immediately. If the headline can be identified during the scrolling operation, it will be a clue to search for information to be viewed. However, it is difficult to discriminate headings in content that moves at high speed by scroll operation, and it is considered that the problem is particularly great for senior users.

  Another method is to prepare a separate page that displays only the headline. In this case, there arises a problem that it is difficult to judge the contents only by looking at the headline. Furthermore, there is a problem in that it is not possible to determine whether the content should be browsed because it is not known how long the content is for the heading.

  On the other hand, with smartphones and tablet devices, it is now possible to input commands using gestures with fingers, and it has become possible to easily perform scaling operations using pinch-out and pinch-in gestures. Although it is possible to easily realize enlargement / reduction using a scroll button attached to a mouse even on a PC, a major feature of a smartphone is that it is possible to simultaneously specify the center point of the part to be enlarged. However, in some web pages for smartphones, the screen may not be enlarged or reduced in order to prevent horizontal scrolling, and it may be difficult for senior users to see characters.

  In a conventional browser for a PC, there are two methods for enlargement / reduction. The first is a method for enlarging or reducing the entire screen. According to this, the entire screen can be enlarged while maintaining the layout. That is, enlargement is performed while maintaining the size ratio between the headline and the text. In general, the enlargement ratio can be changed greatly, such as 200% or more. However, when the enlargement is made, it becomes difficult to grasp the whole instead of making the characters easier to see. The second method is to enlarge / reduce only the text. If the text size is specified relatively, the text can be scaled. Since elements such as images cannot be enlarged or reduced, if the heading and body are made of images and text, the ratio between the size of the heading and the body can be changed. However, generally, since the enlargement ratio of the text is less than 200%, the ratio of the size of the headline and the body cannot be increased. Smartphones and tablet terminals often scale using the first method and cannot scale only text.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[First Embodiment]
As shown in FIG. 1, a web content display device 1 according to the first embodiment is connected to a web server 2 via a communication network.

  The web content display device 1 is configured in a personal computer (PC) or a mobile terminal (smart phone or the like) by software called a browser or the like.

  The web content display device 1 includes a receiving unit 11, an information storage unit 12, a control unit 13, an information processing unit 14, an information input unit 15 (such as a keyboard and a mouse), and an information output unit 16 (such as a display device).

  As shown in FIG. 2, the parameter storage unit 121 included in the information storage unit 12 stores a record for each type of element to be displayed. Each record includes a type ID indicating the corresponding type, a display magnification given to the corresponding type, a reduction factor, an enlargement factor, and a final display magnification.

  As shown in FIG. 3, the control unit 13 determines whether or not a URL (Universal Resource Locator) of a web content to be displayed is input from the information input unit 15 (keyboard or the like) by the user (S1).

  If there is no input, the control unit 13 returns to step S1. If there is an input, the control unit 13 gives a URL to the receiving unit 11, whereby the receiving unit 11 connects to the URL web server 2 and the URL web The content is received from the web server 2 (S3).

  As shown in FIG. 4, the web content includes an HTML (Hyper Text Markup Language) document. In the HTML document (source code), for example, an element “A portal” is sandwiched between tags <title> and </ title>, which indicates that the type of the element “A portal” is “title”. Other types of elements are described similarly.

  Returning to FIG. 3, the control unit 13 gives the web content to the information processing unit 14, and the information processing unit 14 thereby analyzes the web content (S3).

  As shown in FIG. 5, the web content has a hierarchical structure, and the analysis result indicates such a hierarchical structure and elements included in each hierarchy.

  Returning to FIG. 3, the control unit 13 records the analysis result in the information storage unit 12 (S5).

  Next, the control unit 13 reads the display magnification from the parameter storage unit 121 for each type of element (S7).

  Next, the information processing unit 14 renders the web content based on the display magnification, and outputs the web content to the information output unit 16 (display device) (S9), and ends the process.

  As shown in FIG. 6, the element “A portal” corresponding to the type ID “h1” is displayed in the size corresponding to the final display magnification equal to the corresponding display magnification “150%”.

  In addition, the elements “news”, “weather”, and “traffic information” corresponding to the type ID “h2” are displayed in the same size as the corresponding display magnification “125%” according to the final display magnification.

  In addition, the elements corresponding to the type ID “p” “Done yesterday ...”, “Tokyo weather ...”, “Delayed by train ...” correspond to the same final display magnification as the corresponding display magnification “100%”. Displayed in size.

  Here, the finally displayed size corresponds to a product of a predetermined magnification and a final display magnification. The predetermined magnification depends on, for example, the screen size of the information output unit 16 and is different between the portable terminal and the PC.

  For example, if each character of “Done yesterday ...” is displayed with 12 pixels, each character of “A portal” is displayed with 18 pixels, which is 1.5 times as large.

  As shown in FIG. 7, when the web content is enlarged or reduced, the operation is different. Here, it is assumed that web contents that are not enlarged and reduced are displayed.

  As illustrated in FIG. 7, the control unit 13 determines whether an enlargement / reduction ratio is input from the information input unit 15 (keyboard or the like) by the user (S <b> 11). The enlargement / reduction ratio in the enlarged display is larger than 100%, and the enlargement / reduction ratio in the reduced display is smaller than 100%.

  Note that the enlargement / reduction ratio may be input by gestures such as pinch-in and pinch-out on the screen with a finger, an operation of moving the scroll wheel of the mouse, or selection from a pull-down menu.

  If there is no input, the control unit 13 returns to step S11. If there is an input, the control unit 13 acquires the enlargement / reduction ratio, and reads the display magnification, reduction factor, and enlargement factor from the parameter storage unit 121 for each type of element. The information is given to the information processing unit 14 together with the enlargement / reduction ratio (S13).

  The information processing unit 14 calculates the final display magnification for each type of element as follows (S15) and stores it in the corresponding record in the parameter storage unit 121 (S17).

  In step S15, if the enlargement / reduction ratio is greater than 100%, the information processing unit 14 calculates the product of the corresponding display magnification, the corresponding enlargement factor, and the enlargement / reduction ratio as the final display magnification.

  On the other hand, if the enlargement / reduction ratio is smaller than 100%, the information processing unit 14 calculates the product of the relevant display magnification, the relevant reduction coefficient, and the enlargement / reduction ratio as the final display magnification.

  Further, if the enlargement / reduction ratio is 100%, the information processing unit 14 calculates the corresponding display magnification as the final display magnification.

  Next, the information processing unit 14 reads the final display magnification for each element of the web content from the record including the type ID indicating the type of the element in the parameter storage unit 121, and the element corresponds to the final display magnification. The web content is rendered so as to be displayed in size, and is output to the information output unit 16 (display device) (S19), and the process ends.

  As shown in FIG. 8, if the enlargement / reduction ratio is 80%, the element “A portal” corresponding to the type ID “h1” has the applicable display magnification “150%”, the applicable reduction coefficient “1”, and the enlargement / reduction ratio. It is displayed in a size corresponding to the final display magnification “144% (= 150% × 1 × 80%)” which is the product of “80%”.

  In addition, the elements “news”, “weather”, and “traffic information” corresponding to the type ID “h2” have the corresponding display magnification “125%”, the corresponding reduction factor “1”, and the enlargement / reduction rate “80%”. It is displayed in a size corresponding to the final display magnification “100% (= 125% × 1 × 80%)” which is the product.

  In addition, the elements “Yesterday ...”, “Tokyo weather ...”, “Delayed by the railroad ...” corresponding to the type ID “p” correspond to the corresponding display magnification “100%” and the corresponding reduction factor “0. 5 ”and the enlargement / reduction ratio“ 80% ”. The final display magnification is“ 40% (= 100% × 0.5 × 80%) ”.

  Compared with FIG. 6, the elements “news”, “weather”, and “traffic information” are conspicuous, while the elements “done yesterday ...”, “weather in Tokyo ...”, “delayed by the train…” Is so small that it is difficult to read. Therefore, only the elements “news”, “weather”, and “traffic information” can be easily browsed.

  In addition, the elements “done yesterday ...”, “Tokyo weather ...”, “delayed by the railway ...” can be seen, although they are small, so the amount can be known.

  In FIG. 8, the element “Done yesterday ...” is composed of three lines, the element “Tokyo weather ...”, two lines, and the element “late to the railway ...”, and the amount of the element “Did it yesterday ...” I can understand the most.

  Although not shown, if the enlargement / reduction ratio is 200%, the element “A portal” corresponding to the type ID “h1” has the corresponding display magnification “150%”, the corresponding enlargement factor “1.2”, and the enlargement / reduction ratio “ It is displayed in a size corresponding to the final display magnification “360% (= 150% × 1.2 × 200%)” which is a product of “200%”.

  In addition, the elements “news”, “weather”, and “traffic information” corresponding to the type ID “h2” include the corresponding display magnification “125%”, the corresponding enlargement factor “1.2”, and the enlargement / reduction ratio “200%”. Is displayed in a size corresponding to the final display magnification “300% (= 125% × 1.2 × 200%)”.

  In addition, the elements corresponding to the type ID “p” “has been done yesterday ...”, “weather in Tokyo ...”, “late to the railroad ...”, the corresponding display magnification “100%” and the corresponding enlargement factor “1”. And a magnification corresponding to the final display magnification “200% (= 100% × 1 × 200%)”, which is the product of the enlargement / reduction ratio “200%”.

  Compared to FIG. 6, the elements “Done yesterday ...”, “Tokyo weather ...”, “Late late on the railroad ...” are expanded and are difficult to read, but the elements “News”, “Weather”, Since “traffic information” is further enlarged, the same effect as that of the reduction (FIG. 8) can be obtained.

  As shown in FIG. 9, when the enlargement / reduction ratio is smaller than 100%, the final display magnification of the heading element such as the element “news” is larger than the final display magnification other than the heading element such as the element “made yesterday”. large. Therefore, the former element can be easily read. Even when the enlargement / reduction ratio is larger than 100%, the final display magnification of the element “news” or the like is larger than the final display magnification of the element “done yesterday”. Therefore, the former element can be easily read.

  In the first embodiment, the enlargement factor and the reduction factor are used, but only one of them may be used. Alternatively, the same coefficient may be used for both enlargement and reduction. That is, the coefficient may be a coefficient used for at least one of reduction and enlargement.

  According to the web content display device of the present embodiment, the size can be changed for each type of element in enlarged display or reduced display. For example, in the reduced display, the heading element is large enough to be read. While maintaining this, elements such as the text other than the headline can be reduced to a size that the user cannot read. Thereby, only the headline can be selectively read. As a result, it is possible to inform the user of the headline information displayed in a readable size. Thereby, the user can know the outline of the web content.

  In addition, although the size of characters such as text is so large that the characters cannot be read, the amount of text corresponding to the headline can be understood, so the information that the character has cannot be obtained, and only the amount is intuitively conveyed Can do. By displaying characters other than the heading in a size that cannot be read, there is an effect that the user can easily know the amount of text corresponding to the heading.

[Second Embodiment]
Next, a web content display apparatus according to the second embodiment will be described focusing on differences from the first embodiment. The configuration of the web content display device is the same as that shown in FIG.

  As shown in FIG. 10, in the parameter storage unit 121, some reduction coefficients and some enlargement coefficients are replaced with enlargement / reduction prohibition information “N”. Further, the reduction coefficient and the enlargement coefficient that are not replaced with the enlargement / reduction prohibition information “N” are all “1”.

  If the enlargement / reduction ratio is larger than 100% and the enlargement coefficient is replaced with the enlargement / reduction prohibition information “N”, the information processing unit 14 sets the final display magnification to be the same as the display magnification (S15).

  On the other hand, if the enlargement / reduction ratio is smaller than 100% and the reduction coefficient is replaced with the enlargement / reduction prohibition information “N”, the information processing unit 14 sets the final display magnification to be the same as the display magnification (S15).

  As shown in FIG. 11, if the enlargement / reduction ratio is 50%, the element “A portal” corresponding to the type ID “h1” is displayed in the size corresponding to the final display magnification equal to the corresponding display magnification “150%”. Is done. That is, even if the enlargement / reduction ratio is 50%, reduction is prohibited by the enlargement / reduction prohibition information “N”.

  In addition, the elements “news”, “weather”, and “traffic information” corresponding to the type ID “h2” are displayed in the same size as the corresponding display magnification “125%” according to the final display magnification. That is, even if the enlargement / reduction ratio is 50%, the reduction of the corresponding element is prohibited by the enlargement / reduction prohibition information “N”.

  In addition, the elements “Yesterday ...”, “Tokyo weather ...”, “Delayed by the railway…” corresponding to the type ID “p” correspond to the corresponding display magnification “100%” and the corresponding reduction factor “1”. And a magnification corresponding to the final display magnification “50% (= 100% × 1 × 50%)”, which is the product of the enlargement / reduction ratio “50%”. That is, since the reduction coefficient is not replaced with the enlargement / reduction prohibition information “N”, the corresponding element is reduced.

  Although not shown, if the enlargement / reduction ratio is 200%, the element “A portal” corresponding to the type ID “h1” has the corresponding display magnification “150%”, the corresponding enlargement factor “1”, and the enlargement / reduction ratio “200%”. Is displayed in a size corresponding to the final display magnification “300% (= 150% × 1 × 200%)”. That is, since the enlargement coefficient is not replaced with the enlargement / reduction prohibition information “N”, the corresponding element is enlarged.

  In addition, the elements “news”, “weather”, and “traffic information” corresponding to the type ID “h2” have the corresponding display magnification “125%”, the corresponding enlargement factor “1”, and the enlargement / reduction ratio “200%”. It is displayed in a size corresponding to the final display magnification “250% (= 125% × 1 × 200%)” which is the product. That is, since the enlargement coefficient is not replaced with the enlargement / reduction prohibition information “N”, the corresponding element is enlarged.

  In addition, the elements corresponding to the type ID “p” “Done yesterday ...”, “Tokyo weather ...”, “Delayed by train ...” are displayed at the same final display magnification as the corresponding display magnification “100%”. The That is, even if the enlargement / reduction ratio is 200%, enlargement of the corresponding element is prohibited by the enlargement / reduction prohibition information “N”.

  As shown in FIG. 12, when the enlargement / reduction ratio is smaller than 100%, the final display magnification of the heading element is constant at 100% according to the enlargement / reduction prohibition information “N”, and is larger than the final display magnification other than the heading element. large. Therefore, the former element can be easily read. Even when the enlargement / reduction ratio is larger than 100%, the final display magnification of the heading element is larger than the final display magnification other than the heading element, and the final display magnification of the latter is constant according to the enlargement / reduction prohibition information “N”. Therefore, the former element can be easily read.

[Second Embodiment (Modification)]
Next, a web content display device according to a modification of the second embodiment will be described focusing on differences from the first embodiment. The configuration of the web content display device is the same as that shown in FIG.

  As illustrated in FIG. 13, in the parameter storage unit 121 according to the modification of the second embodiment, a part of the reduction coefficients and a part of the enlargement coefficients are replaced with the enlargement / reduction prohibition information “N”. Further, the reduction coefficient not replaced with the enlargement / reduction prohibition information “N” is replaced with the display magnification acquisition function f1 (m), f2 (m),. Further, the enlargement factor not replaced with the enlargement / reduction prohibition information “N” is replaced with the display magnification acquisition function g1 (m), g2 (m),. Here, m represents an enlargement / reduction ratio. Further, the display magnification column is omitted.

  In the modified example of the second embodiment, the information processing unit 14 obtains a function value by applying the enlargement / reduction ratio m as an argument, makes the final display magnification the same as this value, and stores it in the corresponding record.

  As shown in FIG. 14, when the enlargement / reduction ratio is smaller than 100%, the final display magnification of the element “news” changes nonlinearly with respect to the enlargement / reduction ratio m, for example, by the display magnification acquisition function f1 (m) or the like. Can be made.

When the enlargement / reduction ratio is larger than 100%, the final display magnification of the element “news” or the like can be changed non-linearly with respect to the enlargement / reduction ratio m, for example, by the display magnification acquisition function g1 (m). Figure, for example, shows a change in the final display magnification in the case of g1 ^(m) = m ^2.

  The display magnification acquisition function may be used in the first embodiment and the third embodiment described later.

[Third Embodiment]
Next, a web content display device according to a third embodiment will be described focusing on differences from the first and second embodiments. The configuration of the web content display device is the same as that shown in FIG.

  As shown in FIG. 15, in the parameter storage unit 121, some records include element designation information. The element designation information designates a specific element and includes, for example, an id attribute and / or a class attribute used for designating a style sheet.

  The parameter storage unit 121 may include, for example, enlargement / reduction prohibition information “N”. The reduction coefficient and the enlargement coefficient can be set to arbitrary values, and may be 1, for example.

  In the third embodiment, the information processing unit 14 calculates the final display magnification for each element specified by the type ID and the element designation information (S15) and stores it in the corresponding record in the parameter storage unit 121. (S17).

  In addition, for each element, the information processing unit 14 reads the final display magnification from the parameter storage unit 121 from a record including the type ID indicating the type of the element and element designation information indicating the element. Then, the information processing unit 14 renders each element to be displayed at a size corresponding to the final display magnification, and outputs it to the information output unit 16 (display device) (S19).

  For example, if the enlargement / reduction ratio is 200%, the elements corresponding to the type ID “h1” and the id attribute “osusume” are the corresponding display magnification “160%”, the corresponding enlargement factor “1.2”, and the enlargement / reduction ratio “ It is displayed in a size corresponding to the final display magnification “384% (= 160% × 1.2 × 200%)”, which is the product of “200%”.

  For example, if the enlargement / reduction ratio is 50%, the elements corresponding to the type ID “h1” and the class attribute “other than head” are the relevant display magnification “140%”, the relevant reduction factor “0.9”, and the enlargement / reduction ratio. A size corresponding to the final display magnification “63% (= 140% × 0.9 × 50%)”, which is the product of “50%”, is displayed.

  The type ID “*” is a special character indicating all types D. For example, if the enlargement / reduction ratio is 200%, all the elements corresponding to the class attribute “honbun” are products of the relevant display magnification “100%”, the relevant enlargement coefficient “1”, and the enlargement / reduction ratio “200%”. It is displayed in a size corresponding to the final display magnification “200% (= 100% × 1 × 200%)”.

  If the type ID “*” is used, the designation of number 7 and the designation of number 3 may indicate the same element. In that case, a rule such as adopting a larger number may be determined.

  As shown in FIG. 16, some records of the parameter storage unit 121 include element part designation information. The element part designation information “prior to 5” in the figure indicates the part from the first character to the five characters of the element corresponding to the type ID “p”. The element part designation information “6 and after” in the figure indicates the part of the element corresponding to the type ID “p” after 6 characters. That is, for example, the element part designation information designates a part by the number of characters from the head of the element.

  The parameter storage unit 121 may include, for example, enlargement / reduction prohibition information “N”. The reduction coefficient and the enlargement coefficient can be set to arbitrary values, and may be 1, for example.

  In the fourth embodiment, the information processing unit 14 calculates the final display magnification for each part specified by the type ID and the element part designation information (S15) and stores it in the corresponding record in the parameter storage unit 121. (S17).

  Further, the information processing unit 14 reads the final display magnification for each part from the record including the type ID indicating the type of the element and the element part designation information indicating the part in the parameter storage unit 121. Rendering is performed so as to be displayed in a size corresponding to the final display magnification, and the result is output to the information output unit 16 (display device) (S19).

  As shown in FIG. 17, the element “A portal” corresponding to the type ID “h1” is displayed in the size corresponding to the final display magnification equal to the corresponding display magnification “160%”.

  Further, the element “news” corresponding to the type ID “h2” is displayed in the size corresponding to the final display magnification which is the same as the corresponding display magnification “150%”.

  As shown in FIG. 18, if the enlargement / reduction ratio is 80%, the element portions “professional baseball player”, “typhoon No. 20”, “metropolitan area” corresponding to the type ID “p” and the element portion designation information “prior to 5” “Iron” is displayed in a size corresponding to the final display magnification “100%” which is the same as the corresponding display magnification “100%”. That is, reduction is prohibited by the enlargement / reduction prohibition information “N”.

  On the other hand, the element part “Rulster ...”, “has a course ...”, “each road is ...” corresponding to the type ID “p” and the element part designation information “6 and later” is the corresponding display magnification “100%”. The display is displayed in a size corresponding to the final display magnification “80% (= 100% × 1 × 80%)” which is the product of the corresponding reduction coefficient “1” and the enlargement / reduction ratio “80%”.

  The computer program for causing the computer to function as the web content display device of each embodiment can be recorded on a computer-readable recording medium such as a semiconductor memory, a magnetic disk, an optical disk, a magneto-optical disk, or a magnetic tape. It can be widely distributed by being transmitted via a communication network such as the Internet.
