The present invention relates to a Bluetooth IoT keyboard capable of keyboard mapping.

Braille terminal, braille book, voice memo, etc. with braille cell / tactile cell driven by array type actuator of ultra-small ultrasonic motor for recognizing information through finger tactile for the visually impaired It is becoming.

The braille terminal uses a braille cell / tactile cell (haptic) module and an actuator operating method to allow the visually impaired to recognize the braille through the touch.

Piezoelectric linear motor (braille recognition rate 68.1%, 5V drive voltage), polymer dielectric (less than 40% braille recognition rate, 1 ~ 2KV drive voltage), piezoelectric ceramic (100% braille recognition rate, 15V drive voltage), solenoid (braille recognition rate) as tactile cell 100%, 5V driving voltage) are being developed.

As a related art, Patent Registration No. 10-0556863 discloses a "braille keypad structure of a mobile communication terminal and an input method thereof". Conventionally, it is difficult for the visually impaired to know the character input system adopted by each terminal manufacturer, and character input is difficult due to the lack of visual identification of keypad characters. In consideration of these problems, 1, 2, and 3 point input keys are assigned to each of the 6 points of the braille system in the 3 × 4 keyboard structure, and when the keys on the braille keypad are pressed, they are converted to a string of braille systems corresponding to the pressed keys. Becoming; Determining whether a two-point input key is pressed before the pressed key, and if true, reading and sorting the converted numeric string and the previous numeric string; It consists of the step of creating and displaying the corresponding character by performing automata with the sorted number string, and introduced the braille system to enable common character input.

Braille has a 2 × 3 6-point configuration with a total of 64 different dot layouts. The constellation of this point is different to indicate consonants, single vowels, complex vowels, symbols, numbers, punctuation, and abbreviations.

Braille sets the order of the dots, starting from the top left and numbering them to the bottom right. In the following, the notation forms of single and compound phonemes in Braille are given as an example.

1 is an exemplary view showing a single phoneme notation of the braille for the visually impaired, 14 consonants for the consonant, the final consonants of the consonants, 10 neutrals are assigned to each vowel is represented by at least one to three points for each single phoneme.

2 is an exemplary view showing a compound phonetic representation of Braille for the visually impaired. As shown in FIG. 2, in order to indicate the sound of the sound, the sound of the first voice is attached to the front of the single phoneme, and the sign of the sound of the consonant is marked. .

As described above, an example of using one six-point notation for one phoneme is common, but using two six-point notations for a compound phoneme. The plural six-point notation is applied to numbers, punctuation, and abbreviations to overcome the limitation of six-point notation.

As shown in Braille's notation, points are assigned distinctly for each phoneme, so each phoneme can be distinguished through automata and can be used for character combinations.

At the end of 2015, the total number of disabled people in Korea was 302 million, accounting for 5% of the population, and the information and communication sector is an important part of daily life for people with disabilities as well as non-disabled people. As an important means to become. In modern mobile communication terminals, the necessity of applications for people with disabilities from basic functions of mobile communication terminals to various functions in everyday life is also increasing.

The use of smart devices and IoT devices can be a means of rehabilitation for people with disabilities and a tool to improve life convenience. The iPhone, iPad, and iPod developed by Apple have been carefully crafted with due consideration for the access and use of the visually impaired, and in fact, a website on the United States confesses how the iPhone has changed their lives. Easily accessible to the visually impaired.

The advantages of a smart device are that it's portable, personalized, and always connected to the network, allowing you to operate your device while on the go. Most of the domestic mobile applications have many difficulties because they are designed and distributed in an inaccessible way even though there are methods that can be used by people with disabilities.

In order to solve the above problems, a braille keypad of a mobile communication terminal using a braille recognition method for the visually impaired has been developed.

3 is an exemplary diagram showing a braille keypad structure of a conventional mobile communication terminal, wherein a one-point input key 1 is assigned to each position of six points in one-to-one correspondence and indicates one point at a time of key press; A two-point input key (2) for allocating two points for each of the six points of the upper, middle, and lower positions to indicate two points in one key press; A three-point input key (3, 5) which is vertically allocated to the six left and right positions by three points and indicates three points at a time of pressing a key; Consists of one space function key (4) which executes one space of braille input.

The one-point input key 1 is assigned one-to-one correspondence for each position of six points, and is used to mark one point at a time by pressing a key. The two-point input key 2 is assigned to two points for each of the six upper, middle, and lower positions, and is used to mark two points in one key press. The three-point input keys (3, 5) are vertically assigned three points to the left and right positions of six points, and are used to display three points on one key press. The one-space floating function key 4 is located in the middle of the three-point input key and is spaced one space when this key is pressed. One-point input key (1), two-point input key (2), three-point input key (3, 5) is the one-point input key (1) is arranged based on the upper right in consideration of the frequency of input and user convenience The two-point input keys 2 are arranged on the upper left side, and the three-

point input keys

3 and 5 are arranged on the lower left and right sides.

A braille keypad input method of a mobile communication terminal includes the steps of: converting a string of numbers in a braille system corresponding to a pressed key when a key of the braille keypad is pressed; Determining whether the advantage input key is pressed before the pressed key, and if true, reading and sorting the converted numeric string and the previous numeric string; Performing automata with the sorted sequence of numbers to create and display the corresponding character.

When the user inputs Braille, the user inputs the text from the top left to the bottom right in the order of dot notation. For example, when entering a consonant consonant “”, enter in the order of 1, 4, 5.

When the user presses a key on the braille pad on the keypad, it converts to a string of numbers for the pressed key. For example, if the key located in the middle of the right-point input key 1 is pressed, the number 5 is converted. The two-point input keys 2 convert to 1 and 4, 2 and 5, 3 and 6, respectively, and the three-

point input keys

3 and 5 convert to 1, 2, 3 or 4, 5 and 6.

When the conversion of the numeric string is completed, it is determined whether the two-point input key (2) has been pressed before, and if true, the current converted number and the previous numeric string are summed and sorted in ascending order. This operation is performed when the two-digit input key (2) followed by the one-point input key (1) is pressed in the key input for the consonant "ㅎ". Changing it to 5 will help you run an automata.

When you finish sorting the string, use this string to perform automata to execute Hangul combination. Then, the characters created by the Hangul combination are displayed on the display window. Similarly, if you apply a Braille system for English, you can also input English.

However, in mobile communication terminals such as smartphones, the necessity of applications for the disabled (IoT devices) is also increasing in the range of basic functions of mobile communication terminals to various functions in daily life through applications in devices. In order to use the functions of the Internet of Things (IoT) device or smart phone for the disabled, it was not suitable for displaying braille or perceiving it with a touch and there was a limited problem.
