Description

  The present invention relates to a web content presentation technology that clearly indicates the result of accessibility evaluation for web content.

  With the development of information and communication equipment, the Internet has become widespread. Accordingly, information distribution using the Internet has been established as an important social core technology. The web content in the information distribution can be used by various users such as elderly people and visually impaired users (for example, web viewers) and various terminals such as mobile terminals and voice (web) browsers. The thing which considered what can be done (hereinafter referred to as accessibility) is desired.

  Under the circumstances described above, the Web Accessibility Guidelines (hereinafter referred to as Accessibility Guidelines) that describe the check items for Web content accessibility are regarded as important. For example, W3C (World Wide Web Consortium) has been established WCAG 1.0 (Web Content Accessibility Guidelines 1.0) worldwide. In Japan, JIS (Japan Industrial Standard) X 8341-3 “Design Guidelines for Considering Elderly Persons and Persons with Disabilities—Equipment, Software, and Service in Information Communication” (hereinafter simply referred to as JIS) was established. In other words, the web page creator can improve the accessibility of the web page by creating the web page according to accessibility guidelines such as WCAG 1.0 and JIS.

  However, at present, many web contents are not considered for accessibility. Therefore, some elderly people, visually impaired persons, and users using mobile terminals face problems such as inability to operate and information acquisition when using web content.

  In general, when using web content, a location containing a command to move to another web content called a link is selected (for example, clicked with a mouse as a pointing device), and various web content is moved while moving. browse.

  For example, to check the garbage collection date using web content, the following web content browsing procedure is followed.

  (1) Display the web content that serves as the entrance to the target web content group called a home page, and select a link (for example, “life”) that is likely to describe the collection date of the target garbage in the web content To do.

  (2) Since web contents related to “life” are displayed, it is checked whether the garbage collection date is described in the web contents. If not, select a link (for example, trash) that is likely to describe the garbage collection date.

  (3) Web content related to “garbage” is displayed, and a garbage collection date is searched for in the web content.

  As described above, the operation of selecting the link is repeated, and the web content is browsed while moving.

  A user who needs web content in consideration of accessibility also performs the above-described web browsing procedure. However, since the web content of the link reference destination is not always considered for accessibility, content that is not considered for accessibility may be displayed.

  When web content that is not considered for accessibility is erroneously displayed, the user often cannot use the web content, and it is necessary to return to the previous web content by a return operation or the like. Furthermore, since some web contents that are not considered for accessibility may be set to invalidate the return operation, the user often cannot perform any operation.

  For example, if the back operation of the web browser is disabled and the button assigned with the back operation in the web content (the arrow image button) is not given alternative text for reading aloud, Since the image content cannot be read out by a browser having a voice reading unit that reads out the text by voice, a visually handicapped person does not know that the button has a function of returning. As a result, the visually impaired cannot return to the previous page.

As an attempt to solve the above problem, a technique for displaying a link reference destination content in a small window by a predetermined operation (for example, overlaying a mouse pointer on the link) on the link (for example, see Non-Patent Document 1). It has been known. However, in many cases, it is not possible to determine whether accessibility is taken into consideration by the appearance of web content displayed in a small window.

[First Embodiment]
The link destination information display device in the first embodiment is composed of functional blocks. In practice, the link destination information display device is realized by one computer or a plurality of computers. That is, each functional block is realized by computer hardware resources and software resources.

  In the first embodiment, a content display screen size (for example, a web browser window size) is acquired as the content use condition. Note that the content use condition is a condition under which content (content including web content) is presented to the user, for example, a voice browser (a voice generation device including a speaker provided in advance) Using a browser having a voice reading means for reading out text in content via voice, or using it on a PDA (Personal Digital Assistance) or a mobile phone display that does not have a sufficient display area for the content, etc. . In other words, the terms of use are what kind of accessibility is required.

  In the first embodiment, the link destination content referenced from the display target content is evaluated with respect to the content display screen size, and the evaluation is a display that does not change the display screen size of the display target content (for example, color display of the link portion) ) Display the link by method.

  The configuration of the link destination information display device in the first embodiment will be described with reference to FIG. A link destination information display device 1 in FIG. 1 includes a CPU (Central Processing Unit), an OS (Operating System), etc., and includes a calculation means 1a for performing calculation, control of each means and apparatus, and a network communication device. Temporary storage means 1d having content acquisition means 1b for acquiring content from the server 2 via the network 100, usage condition acquisition means 1c, memory, etc., and storing information on the display target web content (for example, the web content itself), A device having content presentation means (for example, a user interface device including a web browser and a display device) 1e for presenting content, for example, a computer device. Further, the calculation unit 1a is based on the link extraction unit 1a2 for extracting (acquiring) a link to the external web content included in the display target web content, the content evaluation unit 1a2 for evaluating the content use condition, and the result of the evaluation. Content editing means 1a3 for editing the content. The link destination information display device 1 is connected to the content server 2 via the network 100. The temporary storage unit 1d may use a partial storage area of a storage unit (for example, a memory or a hard disk device) provided in advance in the computer.

  Next, the link destination information display processing procedure in the first embodiment will be described with reference to FIG.

  First, a content display screen dimension that is a content usage condition is acquired and stored in a memory (S101: usage condition acquisition means 1c). For example, the content display screen size is the window size of the web browser in the content presentation means. The content display screen size is obtained, for example, from the storage area managed by the OS or the like (the storage area in the storage means provided in advance).

  Next, the content to be displayed (hereinafter referred to as display target content) is acquired from the content server 2 (S102: content acquisition means 1b). Here, the display target content includes an HTML (HyperText Markup Language) document and various documents related to the HTML document (for example, a style sheet file, an image file, and a script file).

  Next, a link to the external web content included in the display target web content is acquired and stored as a link database (S103: link extraction means 1a1). An example of the link database will be described with reference to FIG. For example, the link database may be recorded and stored in the temporary storage unit 1d, or may be recorded and stored in a storage unit (for example, a hard disk device) provided in advance. The link database in FIG. 3 includes an ID (Identifier) (ie, link management ID C11) assigned to manage the link, and a URI (Uniform Resource Identifier) of the content referred to by the link (ie, link destination URI C12). , One or a plurality of data sets (hereinafter referred to as link data sets) including the link position (that is, link position C13) in the display target content and the evaluation result (evaluation score C14) of the link destination content referred to by the link. Is.

  In the first embodiment, it is assumed that the link position is described in the XPPointer format. The XPointer is a standard format for designating a predetermined position in the content. For example, the value “#element (/ html / body / p [2] / a [1])” of the link position C13 of the first link data set of the link database in FIG. 3 is a child element of the html element of the HTML document. Among the child elements of a body element, the first a element is shown among the child elements of the second p element. In the first embodiment, XPointer is used, but it goes without saying that it can be replaced with a format having a function of specifying a position in the content.

  Next, the web content indicated by the link destination URI of the link database is acquired (link destination content acquisition) and stored in the content database (S104).

  Next, each web content stored in the content database (more specifically, tag information included in the web content) is evaluated for the content usage conditions, an evaluation score is obtained, and the link database is stored. (S105: content evaluation means 1a2). In the first embodiment, an evaluation is made regarding the content display screen dimensions that are the content usage conditions.

For example, it consists of the following evaluation items.
(Evaluation item A1) “Is it a variable layout instead of a fixed layout?”
(Evaluation item A2) “Is an image larger than the content display screen size included?”
(Evaluation item A3) “Is the content length not more than three times the content display screen size?”
As a method of calculating the evaluation score, out of the evaluation items (diagnostic target items) that match the usage conditions, the score is calculated from the ratio of the number of evaluation items that satisfy the content usage conditions and the total number of evaluation items. The score is calculated in consideration of the weight for each evaluation item and the degree to which the content usage conditions are satisfied.

  Needless to say, other than the above-mentioned items, the content display screen size may be composed of evaluation items. FIG. 4 shows an example of the link database after the evaluation score is given. The value “20” and the value “15” are given to the evaluation score C14 in FIG.

  Next, the display target content is edited so that the evaluation score stored in the link database is expressed by a method suitable for the content use condition (S106: content editing means 1a3). In the first embodiment, as a method of expressing the evaluation score, the reference such as link destination information G in green display, link destination information R in red display, and link destination information Y in yellow display on the screen W1 in FIG. Change the color of the link. By classifying the evaluation score into three levels and assigning three colors of red, green, and yellow, link destination information can be presented by color without causing a change in the dimensions of the content display screen.

  Then, the edited display target content is displayed (S107: content presentation means 1e).

  As described above, in the general web content presentation method, for example, the screen size required to display or operate the linked content is used under the condition that the screen size of the display device such as a display is limited. If it is larger than the screen size that can be displayed, there is a problem that appropriate display cannot be performed, and operation cannot be performed even if displayed.

  Furthermore, if the presentation method that changes the layout of the content to be displayed, such as the screen size required to display the link source content, is increased by inserting the evaluation result of the link destination content, the link source The accessibility of the content has changed and is not appropriate.

  Therefore, in the first embodiment, the link destination information is presented without changing the content display dimension by presenting the link destination information by color.

[Second Embodiment]
In the second embodiment, a link destination information display device is constructed using a server device and a client device. Note that the server device and the client device may be realized by a computer. Needless to say, the server application and the client application may be executed on the same computer.

  In the second embodiment, it is possible to acquire whether or not the voice browser is used as the content usage condition, evaluate the link destination content referred to from the display target content as to whether or not the voice browser is used, and inform the voice browser of the evaluation. An expression method (that is, an expression in which a text that can be read out by voice is given to a link portion) is adopted.

  A link information display apparatus according to the second embodiment will be described with reference to FIG. The link destination information display device 5 in FIG. 6 includes a client device 4 and a server device 3. In the second embodiment, the server device 3 is a so-called proxy server that receives an HTTP (HyperText Transfer Protocol) request from the client device 4 and displays it from the content server 6 via the network 100 instead of the client device 4. The target content is acquired, the display target content is edited as necessary, and transferred to the client device 4.

  The server device 3 in FIG. 6 includes a network communication device, and includes a content acquisition unit 3b that acquires content from the content server 6 via the network 100, a CPU, an OS, and the like, and performs calculation and control of each unit and device. The computer includes a calculation unit 3a, a network communication device, a client communication unit 3c that communicates with the client device 4 via the network 101, a memory, and the like, and a temporary storage unit 3d that stores information related to display target web content. Further, the calculation means 3a is based on a link extraction means 3a1 for extracting (acquiring) a link to external web content included in the display target web content, content evaluation means 3a2 for evaluating content usage conditions, and the result of the evaluation. Content editing means 3a3 for editing the content. The server device 3 may include a storage unit (for example, a memory or a hard disk device) in advance.

  A client device 4 in FIG. 6 includes a CPU, an OS, and the like, and includes a calculation unit 4a that performs calculation, control of each unit and device, a use condition acquisition unit 4b, and a network communication device. 3, a server communication means 4 c for communicating with content 3, a content presentation means for presenting content (for example, a user interface device including a voice browser or a display device) 4 d, and a temporary storage means 4 e having a memory or the like. The temporary storage unit 4e may use a partial storage area of a storage unit (for example, a memory or a hard disk device) provided in advance in the computer.

  A link destination information display processing procedure in the second embodiment will be described with reference to FIG.

  First, an HTTP request is transmitted from the client device 4 to the server device 3 (S201).

  Next, the server device 3 acquires the HTTP request (S202).

  Next, the client device 4 is requested for the content usage conditions of the client (S203), the client device 4 acquires the content usage conditions (S204), and the server device 3 sends a response according to the acquisition of the content usage conditions. Receive (S205) (use condition acquisition means 4b). In the second embodiment, the content use condition is whether or not the content is used by the voice browser. The content usage conditions are stored in advance in a predetermined storage area in the storage unit of the server device 3.

  Next, the server device 3 acquires the display target content specified by the HTTP request from the content server 6 via the network 100 (S206: content acquisition unit 3b).

In steps S207, S208, and S209, as in the first embodiment, a link in the content is acquired (link extraction unit 3a1), and the link is temporarily stored as a link database (for example, the link database in FIG. 3). 3d or recorded and stored in a storage means (for example, a hard disk device or the like) provided in advance, acquires the content indicated by the link destination URI included in the link database, performs a predetermined evaluation (content evaluation means 3a2), An evaluation score is assigned to the link database. In the second embodiment, evaluation related to the voice browser is performed. For example, the evaluation includes the following evaluation items.
(Evaluation item B1) “Is alternative text set for the image?”
(Evaluation item B2) “Are the page title attached?”
(Evaluation item B3) “Are skipping links prepared?”
(Evaluation item B4) "Is the date notation represented by a slash?"
Needless to say, in addition to the above, it may be configured from diagnostic items related to the use of the voice browser.

Next, the display target content is edited so that the evaluation score stored in the link database is expressed by a method suitable for the content use condition (S210: content editing means 3a3). For example, in the second embodiment, as an expression method indicating the evaluation of the linked content, as shown in FIG. 8, it is assumed that evaluation scores Ev1 to Ev9 are inserted into the link portion of the screen W2. Specifically, for example, in an HTML document, the link part is
“<A href =” www. hogehoge. com / zekin. html "> tax </a>"
And the evaluation of the linked content is “20”
“<A href =” www. hogehoge. com / zekin. html "> tax [evaluation: 20] </a>"
As shown, a part “[Evaluation: 20]” indicating the evaluation score is inserted (so that it looks like symbol Ev2 in FIG. 8). The inserted evaluation score can be read out by a voice browser, and the evaluation of the link destination content can be easily understood. It goes without saying that the description format is not limited to the above. In the second embodiment, the method of displaying the evaluation score in the link portion is adopted. However, if the evaluation of the linked content is known, for example, the evaluation score is classified into a predetermined range, and each range is included in each range. It goes without saying that the corresponding text or image may be displayed (for example, “A”, “B”, “C”, “D”, “E”).

  Next, the server device 3 transmits the edited display target content to the client device 3 (S211).

  Then, the client device 4 displays the display target content (S212: content presentation unit 4d).

  It should be noted that some or all of the functions of each means in the linked information display apparatuses of the first and second embodiments are configured by a computer program, and the program is executed using the computer to realize the present invention.
