The braille input/output device according to the patent is characterized by being able to easily input and output braille by connecting to a computer, but there is a problem in that it is inconvenient to use it by connecting to a computer in a certain space, and it cannot be used while carrying.

In addition, although it is possible to input braille to read the braille output on the braille display unit, there is a problem in that the visually impaired people cannot communicate in real time.

The present invention is to solve the above problems, and is to provide a character input device that can be easily carried and communicated with other people through character input anytime, anywhere.

In addition, the present invention is to provide a device that allows the visually impaired to communicate conveniently regardless of the location.

In order to achieve the above object, the present invention, an input unit including a plurality of input keys for inputting braille; An input conversion unit for converting the braille inputted by the input unit into a character code; And a communication unit for transmitting the character code converted by the input conversion unit to an external terminal.

It is preferable that the input unit includes a navigation key between a plurality of input keys for braille input, and the navigation key includes an up/down/left/right movement key and a selection key for selection.

It is preferable that the input unit is arranged in a'T' shape, a braille input key for braille input is provided horizontally, and a special function key is arranged vertically.

The character input device includes a storage unit, and the storage unit stores converted braille including a specific braille, and the input conversion unit searches for the specific braille from the storage unit and includes the specific braille when a specific braille is input. It is desirable to display the converted braille.

When it is determined that the braille input key has been pressed for a certain period of time while the specific braille is input, the character input device may search for the specific braille from the storage unit and display a converted braille including the specific braille.

According to the present invention, there is an advantage in that the visually impaired can easily carry and communicate with each other at any time.

In addition, while maintaining portability, it is possible to minimize inconvenience by providing a relatively large input key.

2 and 3, the braille input device interlocked with an external terminal according to the present invention includes an input unit 100, an input conversion unit 200, a communication unit 300, a pairing switch (not shown), a battery unit 400, It is configured to include an audio output unit 500 and a storage unit 600.

The input unit 100 includes a plurality of input keys, and the input keys are arranged in a main body having a'T' shape.

Specifically, braille input keys 101 to 108 for braille input are arranged horizontally in the upper part of the input unit, and special function keys are arranged in the vertical direction.

The braille input key includes 6 braille input keys 101 to 106 for inputting 6 braille and braille input keys 107 and 108 for moving to the next character without final input when Korean is input. That is, when the initial and neutral voices are input and the braille input keys 107 and 108 are pressed, the input unit recognizes the letters as unsupported and moves on to the input of the next letter.

In this character input device, the braille input keys are arranged horizontally and the special function keys are arranged vertically, so that the braille input keys are operated with fingers other than the thumb, and the special function keys are used with the thumb to make input very convenient. can do.

Among the special function keys, the "MODE" key may be changed to a mode including a Korean mode, an English mode, and a sentence completion mode each time it is pressed alone or in combination with another key, or may include various functions such as a reset of the device.

The Korean mode and the English mode mean a state in which Korean and English input can be performed, respectively, and the sentence completion mode is a state for simply transmitting a sentence after completing a sentence to be transmitted to the other party. This will be described again below.

The above "SPACE" key is used as a shortcut key by opening one space or combining braille keys when entering, and the "SHIFT" key is a special function that supports the connection device by switching between uppercase and lowercase letters during English input or by combining other keys. Support them. Also, the "CTRL" key can be used with other keys to perform user-defined functions.

For example, pressing the "CTRL" key and the braille input key 107 at the same time may position the cursor at the beginning of the sentence. In addition, by simultaneously pressing the "CTRL" key and the braille input key 108, the cursor can be placed at the end of the sentence.

A navigation key 110 is provided in the center between the braille input keys.

Referring to FIG. 4, the navigation keys are provided with movement keys 111 to 114 on the top, bottom, left and right, respectively, and a selection key 115 is provided in the center. Basically, the movement key can be used to move the position of the cursor up, down, left and right. Also, when combined with keys such as SHIFT and CTRL, you can quickly select and edit letters, words, and lines.

If the navigation key is used, a function similar to the braille input keys 107 and 108 can be implemented. That is, if the initial and neutral voices are input and the right movement key 112 of the navigation key is pressed, the input unit recognizes as an unsupported character and proceeds to the input of the next character, and when the middle selection key is pressed, it is used as an enter key and moves to the next line.

The input conversion unit 200 serves to convert braille input by a user into qwerty characters. That is, when the user wants to transmit braille to the other party after inputting braille, the input conversion unit 200 converts a character code corresponding to the input braille. The character code may be ASCII code, Unicode code, or HID code.

The communication unit 300 may include Bluetooth, and may transmit the converted character code to a paired external terminal. The external terminal may be a smartphone, a notebook computer, a tablet PC, or the like.

Specifically, when the user turns on the power for a wireless connection, a nearby wireless signal is detected and the detected terminal is paired. After pairing, the communication unit transmits the character code converted by the input conversion unit to the paired terminal.

Braille input is not transmitted by pressing a separate transmission key, but when braille is input, it is converted into a character code by the input conversion unit 200, and the converted character code by the communication unit 300 is transmitted to the paired external terminal. And, the external terminal converts and outputs the received character code of the QWERTY keyboard. Since there is no need to press a separate key, the user can quickly complete the sentence by entering only the character to be input. Sentence completion mode automatically recognizes the input Braille and converts the characters entered as abbreviations or abbreviations into a single word or letter and transmits them, allowing users to quickly and easily indicate their intention to convey to the other party. There is this.

The battery unit 400 is provided as a secondary battery to supply power, and the audio output unit 500 notifies the content by voice or sound through a speaker when a user presses an input key or an event occurs. Plays a role.

The storage unit 600 stores data obtained by changing a shortcut key or a designated key value previously designated by the user.

For example, as a shortcut key to the storage unit 600,

(안녕하세요?)가

(안녕)으로 단축키가 지정되어 있을 경우 입력변환부에서는

를 포함하는 변환점자를 저장부에서 검색하고 "안녕하세요?"로 변환하여 통신부를 통해 외부 단말장치에 전달하게 된다.

(How are you?)

If the shortcut key is designated as (Hello), the input conversion unit

The converted braille including a is retrieved from the storage unit, converted into “Hello?” and transmitted to an external terminal device through the communication unit.

The above key is a database that allows users to change and designate frequently used shortcuts to increase user convenience, and includes data that designates the position of the SHIFT/CTRL/MODE/SPACE keys to be converted to suit the user. .

In the input conversion unit 200, when a specific braille is input from the input unit, the converted braille including the specific braille is searched from the storage unit and is structured so that it can be transmitted wirelessly.
