BG67578B1 - Devices for communication via digital script - Google Patents

Abstract

The devices according to the present invention enable the “reading” of text by blind or hearing-impaired users by means of solenoids which bounce under their fingers or microvibrators embedded in fingerless gloves, or microvibrators embedded in the back of some vest (garment). The digital script on which the described devices are based does not negate but only provides an alternative to the traditional Braille alphabet for visually impaired users, of sign languages for hearing and speech impaired users as well as of the Chinese writing system Pinyin.

Description

Field of technique

The invention relates to communication devices in which, by means of built-in software for converting written and audio speech into two-digit codes, blind and deaf users read content through the sense of touch.

Prior art

According to data [1] of the World Health Organization, 285 million citizens of the world, of which 39 million are completely blind, and 246 million are visually impaired. Only 5% of books published in Europe are available in Braille format, and in developing countries, where 90% of disabled people live, this percentage is less than 1%. 70 million people are hearing impaired, of whom 80% live in developing countries.

It is known that people with visual impairments mainly use the so-called Braille for reading, where they "read" content through the sense of touch. People with hearing impairments use so-called sign languages, in which the number of words that can be represented by gestures is practically limited.

Patent Application [2] US 5047952 A discloses a communication system for deaf, deaf-blind or mute persons using an instrumental glove. The system includes an instrumented glove for receiving electrical signals indicative of the hand configuration of the first individual. Deformation sensors in the glove flex with hand movement. Each sensor includes a strain gauge and a strain compressor that are connected in series and form two loops in a bridge circuit. The signals from the bridge circuit are amplified and digitized and applied to a computer that includes an adaptive pattern recognition algorithm that responds to hand state vectors to recognize letter characters in hand space. A second person communicates with the first through a computer system using a portable keyboard.

Patent Application [3] Wo 2010130632 A3 presents a glove and a touch screen used for reading information by touch. This glove is used to read information by touch when a finger of such glove touches a screen including at least one area emitting a continuous electric field. This glove contains at least one finger comprising - a flexible, dielectric inner wall capable of accommodating the wearer's finger, an outer wall which is flexible and dielectric, a liquid contained in at least one space between these two walls, and microparticles placed within in this liquid, as said microparticles are electrically charged with the same polarity and can move in this liquid under the action of an electric field.

Patent Application [4] US 6159013 A discloses a portable reading device for the blind consisting of a miniature housing attached to a sleeve that is mounted on the tip of the user's index finger as a thimble. The housing includes an optical sensor array and an electromagnetic unit to display a single printed Braille character on a tactile surface as soon as the user's finger passes over the character. The electromagnetic unit contains six electromagnets for reproducing Braille characters and two other electromagnets for indicating mistracking to the user. The latter two electromagnets are activated when the blind user's finger moves too far up or down while scrolling through a line of text.

Patent application [5] WO 2017069659 A3 discloses a device and method for transmitting and receiving information via Braille. The device is made, for example, of a textile material and includes contact groups which, when in contact with each other, generate and transmit signals defined as raised Braille dots and vibrating signaling devices used to receive signals defined as raised Braille dots .

Patent Application [6] WO 2011145117 A2 discloses a hand-held communication aid for persons with hearing, speech and visual impairments, with normal individuals and with a person with hearing, speech and visual impairments, the communication means comprising a communication means facilitating real-time communication from distance with another communication device, an input means adapted to input at least one type of message input to said communication means; user input submitted to said means of communication by the first user with at least one disability, including visual, hearing and/or speech impairments, the first user communicating via a communication link with at least one second user with no or at least one disability, including visual, hearing and/or speech impaired, a data handler adapted to integrate and disintegrate multiple data elements during transmission and reception of a message in the communication means of the sender and receiver, a data format converter adapted to convert at least one data format in at least one other data format during sending and receiving a message via said means of communication; artificial intelligence tool, etc.

Digital writing is known [7] - Patent application BG No. 112688, in which every written character from every writing system in the world is represented by codes, which are also the consecutive two-digit number of the written characters from the corresponding alphabet. Since the longest script is the Khmer script (Cambodia) - 74 letters, then in the interval from 75 to 98 the main punctuation marks are encoded with two-digit codes, as an international standard, and the codes 00 and 99 are reserved, respectively - 00 for an interval between the words and 99 - to change the language when there is content in another language in the written texts. Since the number of languages in the world is a four-digit number, each language is identified by four digits, which allows, in a text containing content in more than one language, the meaning of the content to be identified with the semantics of the respective language. Numerical writing also allows communication with the fingers of the hands between at least two participants, in which each of them has memorized the consecutive number of the fingers of the hands from left to right - 1, 2, 3 ... 8, 9 and 0 and the consecutive two-digit numbers of the written characters - for the Bulgarian language: a = 01; b = 02; c = 03 ... y = 20; ya = 30; respectively for the Latin alphabet: a = 01; b = 02; c = 03 ... x = 24; y = 25; z = 26, as for any other script.

No devices are known to communicate through digital writing.

Technical essence of the invention

The task of the invention is to offer functional devices for communication with and between users who are visually and/or hearing impaired or have disabilities, in which by means of touch or vibration it is possible for users to recognize two-digit codes of written characters from the respective language, thereby communicating and reading textual content.

The invention is based on generally known facts:

1. Human sense organs are - sight, hearing, smell, taste and sensation. Some of these senses can, to some extent, compensate for the absence of others. For example, finger touch can compensate for the absence of sight when using Braille for the visually impaired. Sign languages compensate to some extent for the absence of hearing; 2. The number of fingers on the hands of homo sapiens is ten; 3. The number of written characters in the writing systems of the world is a two-digit number.

The problem is solved by digital writing communication devices, each comprising a communication means associated with a data format conversion means adapted to convert at least one other data format during the sending of messages via the communication means

Each of the communication devices is connected to a battery-powered microcontroller which is connected to a means of perceiving sensation, the communication device being provided with software for converting text to two-digit codes - digital script, and the means for converting a format of data is equipped with a device for adjusting the speed of transmitted data. The medium of communication is a microcomputer or a personal computer or a laptop or a tablet or a mobile phone and the medium of data format conversion is a device for wireless data transmission using any of WiFi or Blue Tooth or Mobile data technologies.

The means of sensing sensation are micro solenoids or micro vibrators. In a preferred embodiment, the sense sensing means comprises ten solenoids mounted under ten openings for placing the fingers of the user's hands. In another preferred solution, the sensing means is mounted on top of a pair of gloves with cut off fingers and consists of ten micro vibrators.

In another preferred solution, the means for sensing sensation are ten micro vibrators mounted on the back of a vest (garment).

Application (use) of the invention

Users of the described devices must remember the consecutive numbers of the fingers of the hands from left to right 1, 2, 3,...8, 9 and 0 and the consecutive two-digit numbers of the letters of their alphabet. For Bulgarian language: a = 01; b = 02; c = 03; ... y = 29; я = 30. For languages with Latin letters without diacritical marks: а = 01; b = 02; with = 03; ... x = 24; y = 25; z = 26. "Major" letters are coded with double codes: A = 0101; B = 0202; B = 0303; ... Y = 2929; Я = 3030. Punctuation marks are encoded with two-digit codes (international standard concept) in the interval from 75 to 98. Two-digit codes 00 and 99 are reserved, respectively: for a space between words - 00 and for changing the language - 99.

In Chinese Mandarin, the constituent parts are coded with two-digit codes: Initials with codes from 01 to 18 and Finals with codes from 20 to 53.

The languages of the world (they are a four-digit number) are coded with four digits (international standard concept): Bulgarian language - 0001; Czech language - 0002; Danish language - 0003; Dutch language - 0004; English language - 0005; Estonian language - 0006; Finnish language - 0007; French language - 0008; German language - 0009;...other European languages.

Chinese Mandarin - 0100; Chinese Cantonese - 0101;...other Chinese languages and dialects; Hindi - 0200;...other Indian languages; Korean language - 0300; Japanese language - 0400;...other world languages.

Users of the communication device, which is embedded in a vest (clothing), should remember the numbering of the zones (figure 6) on the back where the micro vibrators are mounted.

Users of the device with built-in solenoids (Figure 2) place their fingers over the holes under which the ten solenoids are mounted. Software converts any written text into two-digit codes. Microcontroller 3, powered by a battery, controls the lifting process of the solenoids that touch the fingertips. The user has memorized the numbers of his fingers and the consecutive two-digit numbers of the letters of the alphabet, as well as the two-digit numbers of the punctuation marks. Touching under the fingertips allows to "read" any text in any language. The interval between individual words is encoded with code 00. If the text contains words from a foreign language, the software warns about this with code 99 and the user "reads" the words from the foreign language with the corresponding two-digit codes for this language.

When reading text from Chinese characters, the software converts the syllables of the text into five-digit codes (two digits for Initials, two digits for Finals, and one digit for tone). Thus, each syllable of the Chinese characters is represented and "read" by five digits by touch from the senses 4, Mandarin Chinese is a phonetic syllabic language.

Users of the reading device (Figures 5 and 6) through micro vibrators embedded in the back of a vest (garment) feel the vibrations and recognize words from the text through the two-digit codes for the written characters of the respective language.
