Description

{Braille education system for blind}

The present invention relates to a braille education system and method for the visually impaired, and more particularly, to a braille education system and method for a visually impaired person who perform braille education in cooperation with a smart phone.

In general, Braille consists of 6 points and one dot. In Korean case, the initials, vowels, abbreviations and abbreviations of letters are written. In the case of foreign languages, letters and abbreviations are used. In Chinese case, .

These braille characters are used in the present education method, such as stencil and pencil, and they are different from each other in reading direction. In the case of acquired blind people, tactile sensitivity for reading braille is relatively low. It takes a lot of time to learn perfectly.

It is known that blind people who know how to use braille skill are only 10% of the total blind people. There are some reasons why braille learning is difficult, but the most important reason is the lack of braille education infrastructure. Braille parishes are still in use, and there are no options for textbooks, and even that has not changed for more than a decade. Above all, Braille, which is impossible for self-study, is absolutely necessary for the education workforce for effective learning. As a result, existing Braille education still remains in analog form, resulting in poor quality of education and low learning efficiency.

The Braille information terminal and the Braille output device may be personal computers for the visually impaired. Perkins-type input keyboard and usually 32 braille output displays. Although the input / output configuration is suitable for personal use, the braille cell constituting the display occupies a large part of the price of the device, . It is a device that can be used by people with visual impairments who can use Braille well. The visually impaired, who are inexperienced with braille, have difficulties in using the Perkins type input keyboard, which is different from the braille 6 points. Moreover, it is a burdensome price to buy for braille education, and because it is not a product made for educational purposes, there is also a lack of built-in educational contents.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

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

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

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

The Braille information terminal 100 includes a braille input unit 10, a braille output unit 20, a microprocessor 30, a Bluetooth module 40, a switch button 50 and an enter button 60.

The braille input unit 10 can divide the three points, which are obtained by dividing one point type (6 points) into half, into left and right sides, and the user can input the braille characters. Here, the three buttons on the left side can input 1, 2, and 3 points of the braille from the top, and the 4, 5, and 6 points of the braille can be input from the top three buttons on the right side. In this manner, the user can quickly input the braille using both hands, thereby reducing the fatigue in use.

The braille output unit 20 is a braille display in which the braille is output in the same manner as the braille standard. A total of eight cells including eight pins are arranged in a row horizontally. A user moves his or her finger to the leftmost position of the display You can read it.

The microprocessor 30 receives the digital data received from the smartphone 200 application through the Bluetooth module 40 and processes the data according to an instruction stored in the memory. At this time, the digital data to be received differs in the signal requested according to the learning contents.

The switch button 50 and the enter button 60 are arranged at a predetermined interval on the upper part of the Braille information terminal 100 so that the detection of both hands can be pressed by the user when the user holds the device with both hands, The user can input the intended Braille character.

As a use example, since one point type can be inputted at a time through the braille input unit 10, a point type is inputted to input a word and a sentence, and a switch button 50 is pressed to complete an intended word and a sentence, (60) is pressed, the corresponding data is finally transmitted. For example, in order to input the braille word "ant", the braille input unit 10 is used to input a point shape (4 points), a point shape (1, 2, 3, 5 points) (1, 5 points) and 'ㅣ' (1,3,5 points) of 'ㅁ' in that order. Therefore, every time the point type is inputted, the switch button 50 is pressed to complete the word, and then the enter button 60 is pressed to finally input the completed word. The input braille data is again processed through the microprocessor 30 and transmitted via the Bluetooth module 40. [

The switch button 50 and the enter button 60 can be used more conveniently in place of the use of a smartphone display that is unsuitable for the visually impaired to select learning contents or to control the system.

The smartphone 200 sends a character to the braille information terminal 100 through the application and the blind person reads the sent character through the braille output unit 20 and inputs the read character to the braille input unit 10, , It feeds back the voice input properly.

2 is a flowchart illustrating a braille training method for a visually impaired person according to the present invention.

Referring to FIG. 2, the braille training method for a visually impaired person according to the present invention is first transmitted to the braille information terminal 100 via the Bluetooth module of the smartphone 200, ).

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

Then, the microprocessor 30 processes the contents of the data and sends an instruction to operate the braille output unit 20 (S300).

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

Next, the input data is calculated through the microprocessor 30 and transmitted to the smartphone through the Bluetooth module 40 (S500).

Next, the data transmitted to the smartphone 200 is processed in the application of the smartphone 200, and the learning process is different depending on the type of contents. However, at this stage, the feedback on whether the answer is wrong is transmitted to the speaker In step S600.

The digital data communicating with the Braille information terminal 100 of the present invention is generated and transmitted according to the learning contents list of the application of the smart phone 200. [ The user can check and select the list of learning contents through the announcement, read the braille pattern corresponding to the selected learning content, or perform the test according to the guidance voice command. If you want to input an answer while performing a test, you can input braille and command corresponding to your answer by operating the input button, and check whether the answer is correct according to the result. These learning management systems and learning methods can overcome the shortage of education infrastructure which was pointed out as a problem of existing Braille education.

One point that constitutes braille is very small, about 1.5mm in diameter and 0.6mm in height. Therefore, the key to braille learning is to read braille correctly by tactically distinguishing it. The present invention is composed of learning contents optimized in stages so that braille can be distinguished and read out in a tactile manner by reflecting the characteristics of the Braille learning. The stages of the learning contents are largely classified into the following five types.

(1) learn point location

As mentioned above, the braille is so small that it is very difficult to distinguish each point. Therefore, the tactile perception practice should be preceded so that each of 6 points of braille can be tactically distinguished before studying Hangul. In this step, the user is guided through voice to understand the structure of the braille, determines how many points are output on the braille output unit of the device, inputs the correct answer through the braille input unit, . Repeat the process of performing the tests included in each lesson, organized in order from low to high difficulty. In low difficulty, it is trained to tactically distinguish the position of each point compared with the warm point. In this case, the on-point refers to a point type in which all the pins of six points come up. Based on this point, it is determined how many points are outputted to the right-hand cell. As the difficulty increases, the number of pins that go up will increase, and the point must be tactilely distinguished without the point to compare the output point.

(2) Korean Braille Memorization

If the user has reached the learning level that allows the position of each point of the braille to be separated to some extent through the training of the point location learning, the process proceeds to learning the character. At this stage, a learning content is formed that can memorize the shape of the braille (point shape). It is content that can learn Hangul characters, vowels, punctuation marks, abbreviations and acronyms. There are many difficulties in memorizing each point type. Since 6 points consist of one point type, many points are similar in structure. In the case of consonant, there is a long time do. Therefore, it is possible to make efficient Braille learning through repetition of voice lecture and test that guides number of each point. Each lecture consists of chapters that teach voice to memorize each point type. Each chapter is divided into a step-by-step lesson to enable effective learning.

 At this time, all contents are learned based on the point type of the braille reading (in the case of the braille writing, the shape of the left and right inversion of the reading of the braille), and when the braille is inputted, the point type of the reading standard is inputted instead of writing.

(3) Korean translation training

If the user judges that the Hangul font is learned to some extent through the training of the Hangul Braille memorization, he or she will present the words and sentences with a voice and guide them to input clearly. At this stage, it is aimed to review Hangul fonts memorized in Hangul Braille memorization, and to apply them to induce them to become accustomed to Hangul Braille. We learn how to use Braille in earnest through this process and practice correct Braille use.

(4) Repeat word reading

After the above-mentioned process, we practice to read Braille more fluently. A word braille is output through eight cells of the braille output unit, and a test process is repeated in which the user determines whether a word is read after the user reads it and inputs the word. The test is repeated to read and input the words accurately, and the time spent in the test is measured and stored.

(5) Spell check

The biggest problem when learning a language spoken only is the lack of learning about spelling, which makes it difficult to use characters correctly. Therefore, after the above-mentioned process of tactile reading of Braille, we study spelling for correct use of Braille. Present the sentence by voice, inducing the user to input a part with a spelling that is easy to be mistaken, and perform the test. In this process, we improve the learning efficiency by providing content using media such as swaying. This stage does not apply to middle-sighted people with visual impairments who have already mastered Hangul characters.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It belongs to the scope of right.
