Description

Apparatus and method for managing electronic documents such as PDF that support multiple modes

The following description relates to an apparatus and method for managing an electronic document such as a PDF supporting multiple modes. More specifically, it relates to an apparatus and method for managing an electronic document such as PDF supporting multiple modes such as an output mode of text data or an output mode of braille data.

The reason that the number of people who use Braille is declining is not because braille is difficult, but because of the lack of information provided in braille. Accordingly, it not only solves the problem of atrophy in social, economic, and employment activities of the visually impaired due to 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 or 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 marginalized class according to the electronic document trend. Specifically, as a lot of information is provided as an electronic document rather than being printed on paper, an electronic file including braille data is also provided in the system to the visually impaired.

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 Braille data format The need for a system that supports the creation, distribution, and output of supporting electronic documents is increasing.

In the following description, the transliteration rule template file may refer to a file in which expression formats such as spaces are recorded to express the page title, and a certain symbol is used for the beginning of a table. The processor may generate transliteration data for transliteration by using the merged data exchange file and transliteration rule template file to render the transformed braille data and the transformed transliteration command based on the position value where the character data is arranged on the original document. . Specifically, the processor may render the converted Braille data and the converted Braille command by using a page number and a line number including the text data. Accordingly, the processor may generate the ink data for punctuation in which the position values of the character data in the original text document are indicated by a page change line, a line change line, and the like.

As another embodiment, the processor may add a predetermined transliteration command to the transliteration text file when it is necessary to add expression information within the transliteration engine.

In operation 150 , the processor may encode a tag indicating the punctuation data and the punctuation mark data in an additional object created in the body region of the electronic document. For example, the electronic document may include a header including version information, etc., a body including a plurality of objects, and a cross reference table including location information of the objects. Specifically, the processor may sequentially encode the first transliteration command corresponding to the first format and the Braille data defined according to the first format. For example, when the first format represents a table, the processor may sequentially encode the first transliteration command representing the table and the braille data converted from character data displayed in the table into the additional object. Also, the processor may sequentially encode the first transliteration command and the braille data between a first location tag indicating a start position of the braille data defined according to the first format and a second location tag indicating an end position of the braille data.

In operation 160 , the computing device may output one of an original object included in the body region of the electronic document and an additional object representing the transliteration data according to a user interaction transmitted from the braille information terminal.
