Braille education system for blind people and method {Braille education system for blind}

The present invention relates to a braille education system and method for blind people, and more particularly, to a braille education system and method for blind people in braille education in conjunction with a smartphone.

In general, Braille is composed of six dots, one dot form. For Hangeul, the initial consonants, vowels, species, and abbreviations are written. For foreign languages, alphabets and abbreviations are used. I write it.

These braille points are due to the fact that the writing and reading directions are different when learning using the current teaching methods such as dots and dots. It takes a lot of time to learn perfectly.

Only about 10% of the total visually impaired population is able to use Braille proficiently. Braille learning difficulty is high, but above all, lack of braille education infrastructure is the main reason. Braille parishes, which are cumbersome to use, are still in use, and the textbooks do not have a variety of options and have not changed for more than a decade. Most of all, Braille, which cannot be self-taught, absolutely requires educational personnel for effective learning. As such, the existing Braille education still remains in the analog form, so that the quality of education is low and the learning efficiency is low.

The braille information terminal and the braille output device may be referred to as personal computers for the visually impaired. It includes a Perkins input keyboard and a 32-character braille output display. This input / output unit is suitable for personal business use, but the Braille cells that make up the display make up a significant portion of the device price. Close to It is also a device for the visually impaired who can already use Braille. Visually impaired people who are not good at using Braille have difficulty using Perkins-type input keyboards that have different shapes from 6 points of Braille. In addition, because it is a burdensome price to purchase for braille education and not a product designed for education, there is also a lack of built-in education content.

An object of the present invention for solving the above problems is to provide a braille education system and method for the visually impaired blind and visually impaired people who learn the braille in conjunction with the application of the smart phone can easily adapt and further self-taught.

In the braille education system for the visually impaired to train the braille by interlocking the braille information terminal and the smart phone application of the present invention for achieving the above object, the braille information terminal is divided into three points divided by six points in half Braille input unit for splitting the left and right input braille; A braille output unit for outputting the input braille in the same manner as a braille standard; A microprocessor which receives characters from the smartphone application as digital data and processes data according to instructions stored in a memory; A switch button for completing a word by pressing a button each time a point type is input to the braille input unit; And an enter button for finally inputting the completed word by pressing a button and transmitting the same to a smartphone.

The left three buttons of the input of the braille input unit may input points 1,2 and 3 of the braille from the top, and the right three buttons may input points 4, 5 and 6 of the braille from the top.

The switch button and the enter button may be arranged on the upper end of the braille information terminal to be pressed by the detection of both hands.

The smartphone sends a character to the braille information terminal through the application, and reads the sent character through the braille output unit and inputs it to the braille input unit and transmits it to the smartphone so that it can be fed back correctly by voice.

In addition, the braille training method for the visually impaired of the present invention comprises the steps of transmitting the digital data for the character to the braille information terminal through the Bluetooth module of the smart phone; Receiving the transmitted data through a Bluetooth module of a braille information terminal and processing the received data in a microprocessor; Processing the data by the microprocessor and outputting the data to a braille output unit; Reading the output braille and inputting it to a braille input unit; Transmitting the input data to a smartphone through a Bluetooth module by arithmetic processing on the input data; And outputting feedback on whether the data transmitted to the smart phone is wrong or correct as a voice comment.

As described above, according to the present invention, visually impaired people who learn Braille in conjunction with an application of a smart phone can easily adapt, and further, can learn braille, thereby promoting braille education and contributing to the spread and development of Braille. .

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.

Hereinafter, a braille education system and method for the blind according to an embodiment of the present invention will be described.

1 is a plan view showing a braille education system for the blind according to the present invention.

Referring to FIG. 1, the braille education system for the visually impaired according to the present invention includes a braille information terminal 100 and a smartphone 200.

The braille information terminal 100 is composed of a braille input unit 10, a braille output unit 20, a microprocessor 30, a Bluetooth module 40, a switch button 50 and the enter button 60.

The braille input unit 10 may divide the three points divided by one half (6) in half to the left and right, and the user may input the braille. Here, the left three buttons may input points 1,2,3 of the braille from the top, and the right three buttons may input points 4,5,6 of the braille from the top. As such, the user can quickly input Braille by using both hands in the left and right arrangements, thereby reducing fatigue in use.

The braille output unit 20 is a braille display in which braille is output in the same way as a braille standard. A total of eight pin cells are placed horizontally in a row, and a user moves a finger from the left to the right on the left side of the display. Can read along the way.

The microprocessor 30 receives the digital data received from the smart phone 200 application through the Bluetooth module 40 and processes the data according to the instructions stored in the memory. In this case, the received digital data requires a different signal according to the learning content.

The switch button 50 and the enter button 60 are disposed at regular intervals on the upper part of the braille information terminal 100 so that the user's index finger can press each button when the user grips the device with both hands. Can enter the intended braille.

As an example of use, since one point type can be input at a time through the braille input unit 10, input a point type to input words and sentences, press the switch button 50 to complete the intended word and sentence, and press the enter button. Press 60 to finally transmit the data. For example, to input Braille called 'ant', the braille input of the Hangul Braille 'a' (4 points), 'ㅐ' dot form (1,2,3,5 points) Enter ㅁ 's dot form (1,5 points) and' ㅣ 'dot form (1,3,5 points) in that order. Therefore, each time the input point is completed, press the switch button 50 to complete the word and then press the enter button 60 to finally input the completed word. The input braille data is again processed by the microprocessor 30 and transmitted through the Bluetooth module 40.

In addition, the switch button 50 and the enter button 60 may select a learning content or control the system, thereby replacing the use of a smartphone display which is not suitable for the visually impaired, and thus may be used more conveniently.

The smartphone 200 sends a character to the braille information terminal 100 through the application, the blind person reads the sent character through the braille output unit 20 and input it to the braille input unit 10 by the smartphone 200 If you send it to the voice feedback whether it is correctly input.

2 is a flow chart showing a braille education method for the blind according to the present invention.

Referring to FIG. 2, in the braille education method for the blind according to the present invention, first, digital data on a corresponding problem (character) is transmitted to the braille information terminal 100 through the Bluetooth module of the smartphone 200 (S100). ).

Subsequently, the digital data is received through the Bluetooth module 40 of the braille information terminal 100 and processed by the microprocessor 30 (S200).

Subsequently, the microprocessor 30 processes the content of the corresponding data and sends an instruction on the operation of the braille output unit 20 (S300).

Subsequently, the user reads the output braille, solves the problem, and inputs an answer through the braille input unit 10 (S400).

Next, the input data is arithmetic processing through the microprocessor 30 is transmitted back to the smartphone via the Bluetooth module 40 (S500).

Next, the data transmitted to the smartphone 200 is processed in the smartphone 200 application, and the learning process varies depending on the type of content, but at this stage, feedback about whether the answer is incorrect or not is correct. The sound is output through the voice (voice) (S600).

Digital data communicating with the braille information terminal 100 of the present invention is a request signal is generated and transmitted according to the learning content list of the smartphone 200 application. The user can check and select a list of learning contents through the announcements, and read or read the braille pattern corresponding to the selected learning contents or perform a test according to the guidance speech comment. If you want to enter the answer while performing the test, you can enter the braille and the command corresponding to the answer by operating the input button, you can check whether the correct answer according to the result, you can learn braille alone without a tutor. Such a learning management system and learning method can solve the lack of education infrastructure that has been pointed out as a problem of conventional braille education.

The size of one point of Braille is very small, about 1.5mm in diameter and 0.6mm in height. Therefore, the key to learning Braille is to read it correctly by dividing it tactilely. The present invention is composed of learning contents that are optimized step by step so that the braille can be properly distinguished and read by reflecting the characteristics of the braille learning. The levels of learning contents are classified into five categories as follows.

(1) Learn the point position

As mentioned above, the braille is very small in size and very difficult to distinguish each point. Therefore, tactile recognition exercises should be preceded to tactilely distinguish each of the six points of Braille before learning Hangul dot form. In this step, you will be guided by voice to understand the structure of the braille, determine how many points are output on the braille output of the device, and perform a test to input correct answers through the braille input section. Do it. The lessons are organized in order from low difficulty to high difficulty and repeat the process of performing the tests included in each lesson. At low difficulty, train the tactile distinction of the location of each point compared to the hot point. At this time, the on point refers to a point shape in which all six pins are raised. Based on this on point, it is necessary to determine how many points are output in the right cell. As the difficulty increases, the number of pins increases, and the points must be tactilely distinguished without hot spots to compare.

(2) memorizing Korean Braille

If the user has become a level of learning that can distinguish the position of each point of the braille through the training of the point position learning, now it proceeds to the step of learning the characters. In this step, we construct learning content that can memorize the shape of the braille. It is the content to learn Korean Braille, including Hangul, vowel, punctuation, abbreviation and abbreviation. It is difficult to memorize each point shape, but since the composition of 6 points constitutes one point shape, there are many similar point shapes in the structure, and in case of consonants, it takes a long time to learn separately because the initial and final shapes are different. do. Therefore, efficient braille learning is possible through voice lectures and test repetitions that guide the number of points forming each point shape. The lectures are voice-guided to memorize each point, and each chapter is divided into step-by-step lessons for effective learning.

 At this time, all contents are learned based on the braille reading of braille reading (in the case of braille writing, it has the shape of left and right inversion of braille reading).

(3) Hangul point training

If it is determined that the user has been familiar with the Korean dot pattern through the training of the Korean Braille memorization, the word and the sentence are presented as voices, and the user is clearly guided to input the words. In this step, the objective is to induce the familiarization of Hangul Braille by reviewing the Hangul dot memorization memorized by the Hangul Braille memorization. Through this vocabulary process, learn how to use Braille in earnest and practice the correct use of Braille.

(4) repeat word reading

After going through the steps mentioned above, practice practicing Braille. Repeats the test process of outputting word braille through eight cells of the braille output, reading the word, and determining and entering a word. The output is mainly around three words, and it reads and inputs the data accurately, repeats the test, and measures and saves the time taken to perform the test.

(5) spell check

The biggest problem when learning a language only by voice is that there is a lack of learning about spelling and you cannot use letters correctly. Therefore, after the above-described training to read the braille tactilely, learn to spell for the correct use of braille. Spoken the sentences and encourage them to enter the misspelled parts of the sentence and perform the test. In this process, it improves learning efficiency by providing contents utilizing media such as nursery rhymes. This step is not the case for people with intermediate urban disabilities who have already made good use of Hangul.

Although the embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concepts of the present invention defined in the following claims are also provided. It belongs to the scope of rights.
