Description

APPARATUS AND METHOD OF GENERATING THE ELECTRONIC BRAILLE FILE

The description below relates to an apparatus and method for generating an electronic braille file. More specifically, it relates to a method of generating an electronic Braille file including text included in a word processor such as MS Word or Haeah Hangul (hwp) and the contents of objects such as tables, images, and text boxes.

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 and electronic documents provided by information systems such as public, financial, medical, and educational institutions such as public documents, guides, news, statements, notices and certificates can be visually recognized by the general public, and the visually impaired can also There is an increasing need for a system that supports the creation, distribution, and output of electronic documents that support recognition in the form of Braille data.

As an embodiment, the braille attribute input interface 110 may receive the braille attribute 430 of the image object 410 from the user terminal. Exemplarily, the braille attribute 430 of the image object 410 includes a second BR parameter indicating whether Braille is output or not, a PT parameter indicating the title of a page including the image object 410, and an institution related to the original document. An OM parameter indicating information about the image object 410 , a second PH parameter indicating a paragraph title including the image object 410 , a second PF parameter indicating a footer of a paragraph including an image object 410 , and a script of the image object 410 . It may include at least one of a second SC parameter indicating a description and a third BC parameter indicating a setting value for the image object 410 .

Returning to FIG. 1 again, the braille attribute recording unit 130 may store the encoded braille attributes 220 , 230 , 330 , and 430 described with reference to FIGS. 2 , 3 and 4 in a designated field in the original document. Specifically, the braille attribute recording unit 130 records the braille attribute for the table entity (sign data of the first BR parameter) (inscription data of the TT parameter) (the TN when the entity selected by the user terminal is a table entity) Numeric data for the length value of the parameter) (Numeric data for the length value of the TN parameter) (Numeric data for the length value of the HC parameter) (Numeric data for the length value of the FC parameter) (Numeric data for the length value of the FC parameter) ( The original document related to the description of the table entity according to a format in which the text data of the FC parameter) (numeric data for the length value of the first BC parameter) (the text data of the first BC parameter) are sequentially arranged can be stored in the field of For example, the first BR parameter may represent numeric data of “1” when there is a braille output, and numeric data of “0” when there is no braille output. The first BR parameter may mean digital data having a high value or a low value according to the presence or absence of a braille output.

As an embodiment, the numeric data for the length value of a specific parameter may include a length value corresponding to the number of black characters when the text data of the corresponding parameter are arranged side by side. The length value may also include the number of spaces corresponding to spaces between the text data.

As another embodiment, the text data of a specific parameter represents text data input from the user terminal.

5 is a block diagram of an electronic Braille file generator according to an embodiment. Referring to FIG. 5 , the electronic Braille file generation unit 500 may include a Braille attribute decoding unit 510 , a Hangul data extraction unit 520 , a transliteration text generation unit 530 , and a transliteration unit 540 . . The braille file generating program linked to the word processor may receive the second user interaction from the user terminal. The second user interaction may indicate an interaction requesting to generate an electronic braille file.

The braille attribute decoding unit 510 may decode braille attributes encoded in the original document. The Hangul data extraction unit 520 may extract point role information and text data from a word processor to which a program for generating a braille file is plugged-in. Illustratively, the point role information may include the number of rows and columns of a table object, cell merging information, content in a cell, text box object content, body content, and footnote or endnote content.

The transliteration text generator 530 may generate the transliteration text by using the extracted text data and braille attributes. Specifically, the transliteration text generator 530 may generate the transliteration text by reconstructing the original text according to the transliteration rule based on the Braille attribute of the entity. Exemplarily, if the text content included in the text box object is “second semester transcript” and the PT parameter indicating “page title” in the braille attribute of the text box object has a high value, a point corresponding to the text box object The reversed text may represent the unwritten data of "Page Title: Report Card for Semester 2". The transliteration unit 540 may generate an electronic braille file by translating the transliteration text according to a predefined braille rule.

As another example, if the braille attribute of “page title” is given to the text box object with the content of “payment statement”, the braille attribute is encoded in the hidden field of the text box object (BR:1) (PT:1 ) is stored. In addition, in this case, when a transliteration request is made, the Braille attribute (PT:0) is checked (PT:6), an accessibility tag called “payment statement” is generated, and the transliteration text generator 530 indicates that it should start from the 7th column of the document. According to the Braille book publication guidelines, you can create a reconstructed text for transliteration, such as "(Blank) (Blank) (Blank) (Blank) (Blank) (Blank)Payment Statement".

The computing device executing the Braille file generating program according to the present embodiment may analyze a table of an original document of a word processor such as Hangul below in cell units, and provide text for transliteration corresponding to the analyzed result. In addition, the computing device executing the Braille file creation program processes footnotes, endnotes, and automatic numbers included in word processors such as Hangul below as Braille attributes, so that the visually impaired can access electronic public document files (eg, health insurance qualification certificate). provides a point range of
