Description

Braille input method of braille input and output device and its device {apparatus and method for inputting braille}

The present invention relates to a braille input method and a device thereof, and in particular, the input device of the braille input / output unit is formed by dividing into a braille input unit and a command input unit, and the braille keys of the braille input unit are formed from 32 to 63 for each braille key. By distributing the completed braille of type 63 one by one, and by operating only the braille key or by operating the braille key together with the switch key of the command input unit, it is possible to selectively input the completed braille assigned to each braille key. The present invention relates to a braille input method and an apparatus of a braille input / output device that can provide convenience to a visually impaired person.

In general, Braille is formed by forming a raised point on a thin plate such as paper so that the visually impaired person can read it with the touch of a finger. Such Braille is written by hand or by using a braille input / output device such as a braille typewriter or a braille printer. In the following description, before considering an example of a conventional braille input / output device, the characteristics of the braille will be described first.

Braille is a six-point braille is commonly used as shown in the braille table of Figure 1, the six-point braille forms a unique character system by varying the number and arrangement of dots between 1 to 6, On the other hand, as shown in Figure 2 has a case of type 63, and is used in common throughout the world regardless of the type of language.

In other words, the languages of the world are represented as inherent characters, and the Korean language is Korean, English is alphabet, Chinese is Chinese, Japanese is hiragana or katakana, and Braille is Korean, English, Chinese. Regardless of the type of language, such as Japanese, all of them are written in Braille within the 63-pattern pattern.

For the same reason, Braille is a very efficient character. For example, typewriters can't be used by Korean users, whereas braille typewriters don't care what language the user uses. It is an efficient character.

Hereinafter, a schematic configuration of the aforementioned braille typewriter as an example of a conventional input / output device will be described with reference to FIG. 3. The braille typewriter has a major configuration of a braille output device and a braille input device, among which the braille input device is shown in FIG. As described above, six braille input buttons 110 are configured. According to the conventional braille input device as described above, six braille input buttons 110 may be operated simultaneously to input one complete six-point braille.

On the other hand, the braille input device as described above has been applied to relatively recently developed inventions, and in the case of the invention described in Patent Publication No. 10-0567134 shown in FIG. 4 (2006.04.05. A braille input device composed of buttons 120 is applied.

However, in the conventional braille input device and its input method as described above, since six braille input buttons 110 and 120 are operated simultaneously to form one completed braille, the use of six fingers to input one braille In addition to focusing attention on, the authors of the document are not only mentally and physically tired, but also require a high level of skill in their use.

Hereinafter, referring to FIG. 5, a design proposed in Korean Utility Model Publication No. 20-0189569 (announced on July 15, 2000) as an example of a conventional input device, each letter key of a typical Korean 2 beol type dial 200 The character shown in 230 is rewritten as Braille 235, and the above configuration is not called a braille input device, because the alphabet "S" and the Korean "b" are the same as the example shown in the figure. Notation of Braille is different, and even in the case of Hangul "ㄴ", although the notation of the initial "B" and the final "B" is different from that of the braille table of FIG. This is because it is only displayed again as the braille 250, and the braille is not input.

That is, the above configuration is proposed in the state without consideration and understanding of the position of the visually impaired user and the braille character system, but the general character 200 can easily learn, but the input and output of the braille In this regard, it did not help the visually impaired.

On the other hand, when it comes to a braille printer, a braille printer is used as a peripheral device of a computer like a normal printer, it is equipped with a braille output module in contrast to the general printer is equipped with toner or cartridge as an output module, There is a difference in that it requires a braille conversion software for converting and outputting a general document to Braille. The braille output module applied to the braille printer as described above has been developed and used in various forms.

The present invention is to solve the problems of the conventional braille input and output, it is possible to speed up the input speed in braille input, small and light, easy to carry, braille input method of the braille input and output easy to use and It is an object of the present invention to configure the device and to provide practical conveniences for the visually impaired, thereby ultimately increasing the utilization of the characters that are easily neglected by the visually impaired.

Braille input method of the braille input and output device according to the present invention for achieving the above object, by forming a braille key of 32 to 63, by distributing one or two of the completed braille of type 63 to each braille key by the braille key The braille input / output method of the braille input / output unit is characterized by a single braille input.

The present invention provides a braille input / output unit having a power supply unit, a control unit unit, an input unit unit, and an output unit unit, wherein the input unit unit is divided into a braille input unit and a command input unit. It forms 63 pieces and allocates one or two completed 63 type braille for each braille key, and the command input unit includes a switch key and a space key, and operates only the braille key or operates a switch key and a braille key together. There is another feature of the braille input device of the braille input / output unit to selectively input any one of the completed braille assigned to the character key.

According to the present invention having the above-described configuration, it is possible to speed up the input of braille by inputting one completed braille with one braille key, and the number of braille keys including both numbers and symbols in preparation for a general Korean two-bulk typeface. Can be limited to at least 32, so the Braille I / O unit can be made small and light, so it is easy to carry, and the Braille input program is not only necessary, but also does not require a braille conversion program. By providing convenience regardless of use, ultimately, the visually impaired have an effect of increasing the utilization of letters.
