Most electronic devices used in real life are equipped with an electronic document execution function. However, since most electronic devices employ a graphic user interface (GUI), it is very difficult for a visually impaired person to learn the contents of an electronic document using an electronic device. This is because visually impaired people can acquire information in a limited way by using sound or touch.

In general, visually impaired people widely use braille keyboards (or braille keyboard skins) and text to speech programs to input or output information through electronic devices. However, when an electronic document is output in Braille on a braille keyboard or in a text-to-speech program, the contents described in the electronic document are only transmitted in one direction, so that visually impaired people cannot selectively acquire information about the desired part. When learning electronic documents in such a limited way, the learning effect is bound to be inevitable.

Special text included in electronic documents For example, tables, equations, formulas, and reaction equations contain two-dimensional outline information along with general text information, so use a braille pad or text-to-speech program. Therefore, it was very difficult to deliver these special texts to the visually impaired.

The electronic device 100 may be implemented with various electronic devices, and is of course not limited to the above-described embodiment.

The braille input/output unit 110 is an interface between the visually impaired (or user) and the electronic device 100. The braille input/output unit 110 may detect a touch input, a push input, etc. from a visually impaired person, and transmit the same to the processor 120 to be described later. Also, the braille input/output unit 110 may output braille under the control of the processor 120.

For example, the Braille input/output unit 110 may output special text. Here, the special text may be in an HTML format corresponding to at least one of a table, an equation, a chemical formula, and a reaction equation. The special text may include general text information (hereinafter, text) and two-dimensional outline information. For example, the outline information stores information on an area in which two-dimensional special text is divided into at least one or more areas as coordinate (or pixel coordinate) information, and the text corresponding to at least one divided area is divided into at least one divided area. Mapped to one area and saved. Here, the boundary (or outline) of at least one divided area may be defined as an outline. The braille input/output unit 110 may output an outline of the special text based on outline information of the special text.

The processor 120 may generally control the electronic device 100. The processor 120 may output text included in the special text. For example, when a touch event for at least one of a plurality of regions in an outline output through the braille input/output unit 110 occurs, the processor 120 may output text corresponding to at least one region. . Here, text corresponding to at least one area may be output as braille in a predefined area of the braille input/output unit 110. Here, the predefined area may be an area of the braille input/output unit 110 other than the output outline or an area within the output outline. Here, when the predefined area is an area within the output outline, the processor 120 sequentially converts the text corresponding to at least one area to the braille input/output unit 110 in Braille after the output outline disappears. Can be printed.

Also, the processor 120 may output text corresponding to at least one area as a pre-stored voice.

Referring to FIG. 2, the special text 20 may be a table. 2 shows a periodic table 20 as an example of a table. The periodic table (20) is a table listing all elements existing in nature or artificially created according to their atomic number and chemical properties of the elements. The periodic table 20 is a systemized feature of more than 100 elements, and the chemical properties of substances can be easily predicted.

The columns of the periodic table 20 represent groups of elements, and the groups of elements are composed of groups 1 to 18. The rows of the periodic table 20 represent periods of elements, and the periods of the elements are composed of 1 to 7 periods.

3 shows a portion of the periodic table 20 of FIG. 2. 3, the periodic table 30 includes 5 groups and 4 periods. Here, the size of the periodic table 30 may be defined as 6×5 cells.

4 illustrates a state in which the outline 40 of the periodic table 30 is output to the Braille input/output unit 110. Here, the outline 40 may be defined as an outline of all or part of the braille input/output unit 110. In addition, the black braille pins are protruding and fixed, and the white braille pins may be defined as being inserted and fixed. As an example, referring to FIG. 4, the outline 40 of the periodic table 30 may be formed by protruding and fixing a plurality of braille pins disposed on the braille input/output unit 110.

Here, the plurality of cells 31-1 to 31-6 of the periodic table 30 correspond to the plurality of regions 41-1 to 41-6 in the outline 40 of the braille input/output unit 110, and the periodic table The plurality of cells 32-1 to 32-6 of 30 correspond to the plurality of regions 42-1 to 42-6 in the outline 40 of the braille input/output unit 110, and the periodic table 30 The plurality of cells 33-1 to 33-6 of the Braille input/output unit 110 correspond to a plurality of regions 43-1 to 43-6 in the outline 40 of the braille input/output unit 110, and the plurality of cells of the periodic table 30 The cells 34-1 to 34-6 correspond to a plurality of regions 44-1 to 44-6 in the outline 40 of the braille input/output unit 110, and the plurality of cells 35 of the periodic table 30 -1 to 35-6) may be defined as corresponding to a plurality of regions 45-1 to 45-6 in the outline 40 of the braille input/output unit 110.

For example, a plurality of cells (or a plurality of regions) of the periodic table (special text) 30 (31-1 to 31-6, 32-1, 32-2, 33-1 to 33-3, 34-1 to 34-3, 35-1 to 35-6) may include the corresponding text. In addition, the plurality of cells 32-3 to 32-6, 33-4 to 33-6, and 34-4 to 34-6 of the periodic table 30 may not include a corresponding text.

For example, at least one first region 41-1 to 41-6, 42-1, 42-2, 43-1 to 43 among a plurality of regions 41-1 to 45-6 in the outline 40 -3, 44-1 to 44-3, 45-1 to 45-6) are at least one area 31 containing text among the plurality of cells 31-1 to 35-6 included in the periodic table 30. -1 to 31-6, 32-1, 32-2, 33-1 to 33-3, 34-1 to 34-3, 35-1 to 35-6). In addition, at least one second area 42-3 to 42-6, 43-4 to 43-6, 44-4 to 44- among the plurality of areas 41-1 to 45-6 in the outline 40 6) is at least one area (32-3 to 32-6, 33-4 to 33-6, 34) that does not contain text among the plurality of cells (31-1 to 35-6) included in the periodic table 30. -4 to 34-6).

For example, at least one first region 41-1 to 41-6, 42-1, 42-2, 43-1 to 43 among a plurality of regions 41-1 to 45-6 in the outline 40 -3, 44-1 to 44-3, 45-1 to 45-6) may include at least one braille pin protruding and fixed. For example, four braille pins 41-2-1 included in a region 41-2 in the outline 40 are protruded and fixed. In this case, there may be one or more braille pins 41-2-1 protruding and fixed. Here, the protruding and fixed braille pin 41-2-1 indicates that there is text corresponding to the one area 41-2.

As another example, at least one second region 42-3 to 42-6, 43-4 to 43-6, and 44-4 to 44 among a plurality of regions 41-1 to 45-6 in the outline 40 -6) may include at least one braille pin inserted and fixed. For example, all braille pins included in one area 44-6 in the outline 40 are inserted and fixed. Here, the embedding-fixed braille pin 44-6-1 indicates that there is no text corresponding to the one area 44-6.

For example, one of the plurality of areas 41-1 to 45-6 in the outline 40 includes a plurality of braille pins arranged in a diagonal direction and protruding and fixed. Here, a plurality of braille pins arranged in a diagonal direction and protruding and fixed may be recognized as marks indicating the corners of the table 30.

As an example, at least one of the braille pins protruding and fixed in one region 42-2 of the plurality of regions 41-1 to 45-6 in the outline 40 is touch input. In this case, the processor 120 may output text corresponding to the one region 42-2, for example,'hydrogen' or'hydrogen'.

As another example, when a plurality of regions 42-2 and 43-2 among a plurality of regions 41-1 to 45-6 in the outline 40 are sequentially touch input, the processor 120 Text corresponding to (42-2, 43-2), for example,'lithium' and'beryllium', or'lithium' or'Beryllium' can be continuously output.
