Description

APPARATUS AND METHOD FOR FACILITATING THE GENERATION OF ELECTRONIC BRAILLE FILES

The description below relates to devices and methods that support the creation of braille files. More specifically, including braille properties for hidden property values for web pages, electronic bulletin board pages, or documents attached to the web having a DOM (document object model) structure as well as HTML (hypertext markup language) structure. It relates to an apparatus and method for supporting the creation of an electronic Braille file.

The reason that the number of people who use braille among the visually impaired is declining is not because braille is difficult, but because of the lack of information provided in braille. As mentioned above, it not only solves the problem of the visually impaired social, economic, and job hunting due to the lack of information, but also provides the visually impaired with a sense of identity and confidence as a member of society, and promotes social advancement and economic growth through academic and job performance. And for job hunting, it is required to build an infrastructure to provide braille information to various information systems.

In particular, various methods have been proposed to build an information system infrastructure for the information underprivileged according to the electronic document trend. Specifically, as a lot of information is provided as electronic documents rather than printed out on paper, electronic files including Braille data are provided in the system to the visually impaired as well.

Specifically, various document formats provided by information systems such as public, financial, medical, education, etc., such as bills, receipts, statements, notices and certificates, can be visually recognized by the general public, and the visually impaired can also be recognized in the form of Braille data. The need for a system that supports the creation, distribution, and output of supporting electronic documents is increasing.

Conventionally, because HTML format was used in the process of implementing web pages, blind people could access all information of objects such as tables (eg table titles, cell contents, etc.) with a screen reader program. However, recently, JavaScript-based UI/UX tools that automatically draw tables and support page sorting by passing only input data to be uploaded to a web page have been used. It is difficult for the disabled to access the web page screen using the conventional screen reader program.

Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. In the description with reference to the accompanying drawings, the same components are assigned the same reference numerals regardless of the reference numerals, and overlapping descriptions thereof will be omitted.

In the following description, moji (墨字, regular print) is a general character and represents a term that contrasts with Braille (點字) for the visually impaired. Therefore, the text for transliteration described in this specification is arranged with the Braille properties and the original text written in ink so that the visually impaired can understand the object properties such as tables, text boxes, or images included in the electronic document as well as the original text. It means silent data. In addition, the braille attribute represents a value indicating the structure of a document and a method of translating the original document into braille in braille data as ink data.

1 shows an exemplary screen for explaining accessibility to a web page for visually impaired people. When a visually impaired person accesses a table written in a conventional HTML structure with a screen reader program, he/she enters the first cell 110 in the upper left. After that, the visually impaired can move to the desired cell 120, 130 such as up, down, left, or right using shortcut keys such as direction keys. read the contents

However, when entering a table on a web page created based on a recent UI/UX tool, data does not have a structure in which data is output on the screen. Exemplarily, even when the right cell movement shortcut key is pressed in the upper left cell 110 , there is a case in which the movement is not to the right cell 130 but to the down cell 120 . Also, the first cell entered through the screen reader program is not the first cell 110 in the upper left, but moves according to the hidden DOM structure, such as starting from the middle cell or moving the header cell of the table to the end. As described above, when a visually impaired person cannot move to a desired location using a screen reader program, accessibility to a table is defined as low.

2 is a block diagram illustrating a device supporting generation of an electronic braille file. Referring to FIG. 2 , the device 200 supporting generation of an electronic braille file may include a web data extractor 210 and a web data encoder 220 . The device 200 supporting the generation of the electronic braille file may be implemented at least temporarily by a processor included in the computing device. The processor may support generation of an electronic braille file by extracting a hidden attribute value from a web browser with respect to a web page generated with an HTML structure or a DOM structure.

When a designated web page is executed, the device 200 supporting the generation of the electronic braille file may execute a program for generating a braille file linked to the web page. The braille file generating program is plugged into a web browser, and supports generation of an electronic braille file corresponding to a web page. A computing device executing the program for generating a braille file may add a menu for downloading an electronic braille file to a predetermined location of a web page. For example, the menu button generated by the computing device may include at least one of a debugging file download button, an electronic braille file download button, an Excel file download button, and an accessibility screen view button.

The web data extraction unit 210 may add a braille attribute to a conventional HTML tag when generating a web page. In addition, the web data extraction unit 210 may extract braille attributes and web data from an HTML source for a web page by using the HTML tag information according to a request of the braille file generating program.

As an embodiment, when a table object is included in the web page, the web data extraction unit 210 may include a data-brl-tbltype parameter indicating the type of the table object as a Braille attribute for the table object, the entire table object The data-brl-rowsize parameter indicating the row size, the data-brl-colsize parameter indicating the total column size of the table object, and the data-brl-repeat-header parameter indicating the number of header rows in the repeat of the table object can be extracted. there is.

As another embodiment, when at least one cell of a table object is included in the web page, the web data extraction unit 210 may include data-brl-x indicating the x-coordinate of a specific cell as a braille attribute for the at least one cell. A parameter, a data-brl-y parameter indicating the y-coordinate of the specific cell, and a data-brl-flag parameter indicating a division value of the specific cell may be extracted. Specifically, the data-brl-x parameter and the data-brl-y parameter may be characterized in that a reference point is determined according to the size of each of the data-brl-rowsize parameter and the data-brl-colsize parameter. A detailed description of the operation process of the web data extraction unit 210 will be further described together with drawings to be added below.

The web page encoding unit 220 may encode the extracted braille attributes and web data in accordance with a predefined format. As an embodiment, the web page encoder 220 may include a tag name for a braille attribute in a table tag for a table object included in a web page or a td tag for a cell of the table object, a delimiter, and a parameter for the tag name A transmission message for transmission to a designated server can be generated according to an encoded message format in which tag values including

Although not shown in FIG. 2 , the device 200 supporting generation of the electronic braille file may further include a communication unit (not shown). The device 200 supporting the generation of the electronic braille file may communicate directly or indirectly with another computing device (not shown) through a communication unit. The communication unit may include a communication interface. For example, the communication interface is WLAN (Wireless LAN), WiFi (Wireless Fidelity) Direct, DLNA (Digital Living Network Alliance), Wibro (Wireless broadband), Wimax (World Interoperability for Microwave Access), HSDPA (High Speed Downlink Packet Access), etc. wireless Internet interface of Bluetooth™, RFID (Radio Frequency Identification), Infrared Data Association (IrDA), UWB (Ultra-Wideband), ZigBee, NFC (Near Field Communication), etc. can do. In addition, the communication interface may indicate any interface (eg, a wired interface) capable of performing communication with the outside. The communication unit may transmit the message for transmission generated by the web page encoder 220 to a server that generates an electronic braille file.

FIG. 3 is an exemplary view for explaining the operation of the web data encoder described in FIG. 2 . Referring to FIG. 3 , a table object 310 output through a web page is illustrated. In the case of the conventional method, when the user presses the down key button in the cell in which the "address" included in the table object 310 is recorded, it moves to the cell in which the "name or name" is recorded. In this case, when the user presses the down-key button again, it moves to "Geumcheon-gu, Seoul", and when the user presses the down-key button again, it moves to "Honggil-dong". When a visually impaired person who cannot visually recognize the structure of a table uses a conventional screen reader program, there is a cell that cannot be accessed with only the down key button (eg, a cell in which "registration number" is recorded), Since the entity 310 has two rows of headers, there is a practical difficulty in connecting the contents of the table to the visually impaired.

The web data encoding unit according to the present embodiment supports to easily and accurately deliver the contents of a complex table to the visually impaired by encoding the text data in such a way that a predetermined blank character is inserted between the contents of the cell. For example, the web data encoding unit may generate encoded data for delivering the structure of a table to the visually impaired by arbitrarily inserting data indicating a predefined space character between text data corresponding to different cells. . In the case of the embodiment of FIG. 3 , for example, "O" is used as a blank character, and the web data encoder may generate the encoded data 320 for the table object 310 .

FIG. 4 is an exemplary view for explaining the operation of the web data extractor illustrated in FIG. 2 . Referring to FIG. 4 , a table object 410 output through a web page is illustrated. The web data extraction unit may add a braille attribute to an HTML tag written to generate a web page, and extract web data from a web page source using tag information added in response to a request for an electronic braille file.

For example, the web data extractor may add braille properties as shown in Table 1 below to the <table> tag for the table object.

parameter braille properties data-brl-tbltype Table type (1: Vertically repeating table, 2: Horizontally repeating table, 3: Crosstab, 4: Custom table, Template table) data-brl-rowsize Total row size in table data-brl-colsize Total column size in table data-brl-repeat-header Number of repeat header rows in table

Also, the web data extractor may add braille properties as shown in Table 2 below to the <td> tag for cells included in the table object.

parameter braille properties data-brl-x cell's x-coordinate value data-brl-y cell's y-coordinate value data-brl-flag Cell Break Values (1: Table Title, 2: Table Header, 3: Repeat)

In the case of the table object 410 shown in FIG. 4 , the web data extractor may generate the HTML source 420 to which the Braille attribute is added. The web data extraction unit may extract the braille attributes and web data recorded in the HTML source 420 when a request for generating an electronic braille file is called according to a user interaction from the braille file generating program. Specifically, for the table object 410 of FIG. 4 , the web data extraction unit adds “1” to the data-brl-tbltype parameter because the table type is a vertical repeating table, and data according to the total row size of the table object 410 Add “4” to the -brl-rowsize parameter, and add “3” to the data-brl-colsize parameter according to the total column size of the table object 410 . In addition, the web data extractor adds “1” to the data-brl-repeat-header parameter according to the number of header rows in the repeat section of the table object 410 .

In addition, the web data extractor may define "payment details", which is the first cell in the upper left, as reference coordinates corresponding to (0,0). In this case, the cell corresponding to the "payment method" may be assigned a coordinate value of (2,0). Since the total column size of the table object 410 is "3", (2,0) is given to the "payment method", which is the first cell on the right. According to the above method, the web data extraction unit is a reference point for defining the data-brl-x parameter and the data-brl-y parameter according to the respective sizes of the data-brl-rowsize parameter and the data-brl-colsize parameter. can be set.

5 is a block diagram illustrating a server that generates a braille file for a web page. Referring to FIG. 5 , a server 500 that generates a braille file for a web page may include a communication unit 510 , a transliteration text generation unit 520 , and a transliteration unit 530 . The communication unit 510 may receive a transmission message including encoded braille attributes and web data from a device supporting generation of an electronic braille file. Since the description of FIG. 2 may be applied to the hardware structure of the communication unit, a redundant description will be omitted.

The braille text generator 520 may decode the encoded braille attribute. Also, the transliteration text generator 520 may generate the transliteration text by using the extracted text data and braille attributes. The transliteration unit 530 may generate an electronic braille file by translating the transliteration text according to a predefined braille rule.

The device supporting the generation of the electronic braille file according to this embodiment provides a braille file transliterated according to the transliteration guidelines for not only the HTML (hypertext markup language) structure but also the DOM (document object model) structure of the table in the web page. It provides a supportive effect. In addition, the device supporting the generation of the electronic braille file provides the electronic braille file as well as the conventional screen reader program method for the web page, thereby providing the effect of increasing accessibility to the web page for the visually impaired.
