Description

Technical Field

[0001] The present application relates to the field of Braille technology, and in particular to a method, device, storage medium and equipment for inputting phonetic and pictographic Chinese Braille characters. Background Art

[0002] With the rapid development of computer technology, using computers for information processing has become a basic ability for modern people. Taking into account the application needs of the blind, the current computer input for Braille usually uses a screen reader to convert the text content displayed on the screen into voice or convert the text into Braille content that the blind can touch. Using a specific Braille display device, the blind can read and input information by touching the Braille on the Braille display device, realizing human-computer interaction.

[0003] However, the Braille reading and input achieved by these types of Braille display devices is not only expensive but also inconvenient for blind people to use. This is because these devices still use Chinese symbolic Braille, such as current Chinese Braille, Chinese double-pinyin Braille, Chinese universal Braille, or semantic phonetic Braille, which are difficult to learn, use, read, and write. As a result, blind people are forced to memorize symbolic Braille to input and read Braille. Not only is this incomprehensible to ordinary sighted people, but it also greatly reduces the Braille input experience for blind people, making it less practical. Summary of the Invention

[0103] As a special group, the blind need more care and attention from society. Braille serves as a bridge for the blind to communicate with society. It is particularly important to reduce the difficulty of learning Braille, increase the blind's interest in learning, and improve the efficiency of Braille input through input devices (such as keyboards or screens) so that they can better integrate into social life.

[0104] At present, the existing Braille is usually Chinese current Braille, Chinese double-spelling Braille, Chinese universal Braille or Chinese symbol Braille such as semantic phonetic Braille.

[0105] The current Chinese Braille system, composed of initial Braille, final Braille, and tone Braille, is a phonetic Braille system. It uses only pinyin, omits tones, lacks pictograms, and uses spaces to separate words. This is significantly different from the phonetic-sounding Chinese characters used by sighted people. This leads to four problems: First, because initial Braille and final Braille adopt Western symbolic Braille, in accordance with the principle of alphabet internationalization, instead of inventing Chinese pictographic Braille, the resulting system is cluttered with numerous dots, lacks meaning, and is difficult to learn, use, read, and write. This forces blind people to memorize symbolic Braille, while sighted people cannot understand it. Second, because 95% of the tones are omitted, phonetic representation is inaccurate, forcing blind people to guess, which affects tactile reading efficiency. Third, because there is no pictographic Braille system, there is no correspondence between the phonetic-sounding Chinese characters used by sighted people, resulting in unclear meaning, forcing blind people to guess, which affects comprehension efficiency. Fourth, because there is no pictographic Braille system, spaces are required to separate words, wasting space and failing to meet the needs of blind people.

[0106] The Chinese Universal Braille retains the existing Braille initials, finals, tones, and punctuation marks, without changing, deleting, or adding any symbols. It merely refines the existing Braille tone marking rules and standardizes the use of tone marks. While this represents a continuation and development of the existing Braille, featuring a seamless transition between the old and new, accurate pronunciation, time-saving and convenience, and facilitates information technology, it still does not address the issues of semantic representation or the standardization of continuous segmentation.

[0107] Chinese Double Pinyin Braille abandons the principle of alphabet internationalization. Based on the "Hanyu Zhuyin Fuhao," it decomposes vowels into medials and finals, combines initials and medials into medial-medial-vowel ...

[0108] Semantic Braille combines initials, medials, tones, finals, and semantic punctuation into a 16-dot square. However, like the aforementioned double-pinyin Braille, it violates the "Hanyu Pinyin Scheme" and is difficult to understand, learn, and use.

[0109] As can be seen, the aforementioned Chinese sign Braille, including current Chinese Braille, Chinese double-pinyin Braille, Chinese universal Braille, and semantic phonetic Braille, generated according to the internationally accepted Braille symbol ordering system, are all difficult for blind people to learn, use, read, and write. Blind people are forced to memorize sign Braille for input and reading, which is a poor user experience and makes sighted people completely unable to understand these sign Braille.

[0110] To address the above-mentioned defects, the present application provides a method for inputting pictographic and phonetic Chinese characters in Braille. First, after determining the target pictogram and target Chinese pinyin corresponding to the target Chinese character to be input, the target pictogram Braille corresponding to the target pictogram is mapped to the pictogram key position in the input device; and the target Chinese pinyin Braille corresponding to the target Chinese pinyin is mapped to the pinyin key position in the input device; wherein, the target pictographic Braille is a target pictographic ideographic Braille or a target pictographic sign Braille; the target Chinese pinyin Braille is a target Chinese pictographic Braille or a target Chinese sign Braille; the target Chinese pinyin is used to represent the main semantics and pronunciation of the target Chinese character; then, in response to the user's triggering operation on the pictogram key position and the pinyin key position in the input device, the target pictographic Braille and the target Chinese pinyin Braille in the target pictographic and phonetic Chinese character Braille corresponding to the target Chinese character can be generated to realize the input of the target pictographic and phonetic Chinese character Braille.

[0111] As can be seen, since the present application first determines the target pictographic Braille corresponding to the target pictographic symbol of the target Chinese character to be input and the target phonetic Braille representing the main semantics and phonetics of the target Chinese character, the target pictographic Braille and the target phonetic Braille are mapped to the pictographic key position and phonetic key position in the input device, respectively. In this way, the user only needs to trigger these key positions in the input device to input the target pictographic Braille corresponding to the target Chinese character composed of the target pictographic Braille and the target phonetic Braille. The target pictographic Braille inputted in this way inherits all the advantages of pictographic Chinese characters: unified glyphs, complete form and phonetic information, no need for abbreviations, no need for guessing pronunciation and meaning; no gaps between squares, no spaces between characters, no need for space separation, short length, concentrated information, easy to learn, use, read and write. Not only does it make it easier for blind people to learn Braille and input Braille more quickly and accurately, it also makes Braille understandable to sighted people, further expanding the scope of Braille's application.

[0112] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0113] First embodiment

[0114] See Figure 1 , which is a schematic flowchart of a method for inputting form-sound Chinese Braille provided in this embodiment. The method includes the following steps:

[0115] S101: After determining the target form symbol and the target Chinese pinyin corresponding to the target Chinese character to be input, map the target form symbol Braille corresponding to the target form symbol to the position of the form symbol key on the input device; and map the target Chinese pinyin Braille corresponding to the target Chinese pinyin to the position of the pinyin key on the input device; wherein, the target form symbol Braille is the target form symbol pictographic Braille or the target form symbol notation Braille; the target Chinese pinyin Braille is the target Chinese pictographic Braille or the target Chinese notation Braille; the target Chinese pinyin is used to represent the main semantic and phonetic of the target Chinese character.

[0116] In this embodiment, any text that needs to be input by the user in Braille form using the method provided in this embodiment is defined as the target Chinese character to be input. And, in order to facilitate the blind to learn Braille more simply, and input the Braille corresponding to Chinese characters more quickly and accurately, and also in order to allow sighted people to understand Braille, so as to expand the application scope of Braille, after determining the target Chinese character that the blind person wants to input in Braille form through the input device, first, the target form symbol and the target Chinese pinyin (including the target initial, the target final, and the target tone) corresponding to the target Chinese character to be input can be determined. Among them, the target Chinese pinyin is used to represent the main semantic and phonetic of the target Chinese character. For example, assuming the target Chinese character to be input is "盲", then the target form symbol and the target Chinese pinyin corresponding to it can be determined as "目" and "máng" respectively, and the target initial, the target final, the target tone in the target Chinese pinyin "máng" are "m", "ang", and "the second tone ˊ" respectively.

[0117] Among them, this application does not limit the specific Braille type and content of the target form symbol Braille and the target Chinese pinyin Braille, which can be set according to the actual situation. For example, the target form symbol Braille can be, but is not limited to, the target form symbol pictographic Braille or the target form symbol notation Braille, and the target Chinese pinyin Braille can be, but is not limited to, the target Chinese pictographic Braille or the target Chinese notation Braille (such as current Chinese Braille, Chinese double-pinyin Braille, Chinese general Braille or semantic type phonetic Braille, etc. of Chinese notation Braille).

[0118] Furthermore, to facilitate the blind person to input the target pictographic Braille and the target Chinese phonetic Braille corresponding to the target Chinese character in a left-to-right (or right-to-left) order, the target pictographic Braille and the target Chinese phonetic Braille can be mapped to the pictographic key positions and the phonetic key positions of the input device, respectively, according to the different key structures of the input device. Then, by executing the subsequent step S102, the blind person can trigger these key positions on the input device to input the target pictographic Braille more conveniently and accurately.

[0119] S102: In response to the user's triggering operation on the pictographic key position and the pinyin key position in the input device, generate target pictographic Braille and target Chinese pinyin Braille in the target pictographic and phonetic Chinese character Braille corresponding to the target Chinese character to realize the input of the target pictographic and phonetic Chinese character Braille.

[0120] In this embodiment, after the target pictographic Braille and the target Chinese phonetic Braille are respectively mapped to the corresponding pictographic key positions and phonetic key positions in the input device (keyboard or screen) in step S101, the blind person can further input the target pictographic Braille and the target Chinese phonetic Braille Braille in sequence from left to right (or from right to left) by triggering these key positions (i.e., pictographic key positions and phonetic key positions) mapped to the target pictographic Braille and the target Chinese phonetic Braille Braille.

[0121] Furthermore, in response to a user triggering operation on the corresponding pictographic key position and pinyin key position in an input device (keyboard or screen), the Braille corresponding to the target pictographic Braille and the target Chinese phonetic Braille input by the user can be obtained. Then, the target pictographic Braille and the target Chinese phonetic Braille input by the user can be used in sequence from left to right (or from right to left) to form the target pictographic Braille corresponding to the target Chinese character, thereby realizing the input of the target pictographic Braille. The target pictographic Braille and / or the target Chinese character corresponding thereto can be displayed on a display device (such as a computer display screen).

[0122] In a possible implementation of the embodiment of the present application, when the target pictographic Braille is a target pictographic Braille and the target Chinese Pinyin Braille is a target Chinese pictographic Braille, the implementation process of "mapping the target pictographic Braille corresponding to the target pictographic symbol to the pictographic key position in the input device; and mapping the target Chinese Pinyin Braille corresponding to the target Chinese Pinyin to the Pinyin key position in the input device" in the above step S101 can specifically include: first, mapping the target pictographic Braille corresponding to the target pictographic symbol to the pictographic key position in the input device; wherein the target pictographic Braille is a pictographic Braille that simulates the shape of an object related to the target Chinese character. Then, after determining the target initial consonant, target final vowel and target tone corresponding to the target Chinese Pinyin, the target initial consonant pictographic Braille corresponding to the target initial consonant, the target final vowel pictographic Braille corresponding to the target final vowel and the target tone pictographic Braille corresponding to the target tone are respectively mapped to the initial consonant key position, the final vowel key position and the tone key position in the input device.

[0123] The target initial Braille symbols simulate the tongue and lip positions and methods used when pronouncing the target initials; the target final Braille symbols simulate the tongue and lip movements and directions used when pronouncing the finals; and the target tone Braille symbols simulate the pitch changes of the tones. The target Chinese Braille symbols include the target initial Braille symbols, the target final Braille symbols, and the target tone Braille symbols. Pinyin key positions include the initial consonant key positions, the final vowel key positions, and the tone key positions.

[0124] Specifically, in this implementation, the target pictographic Braille corresponding to the target pictographic symbol can be determined by simulating the shape of an object related to the target Chinese character. Furthermore, the target initial Braille corresponding to the target initial can be determined by simulating the tongue-lip pronunciation position and pronunciation method when pronouncing the target initial. The target initial Braille corresponding to the target initial can be determined by simulating the tongue-lip movement trajectory and movement direction when pronouncing the final. The target tone Braille corresponding to the target tone can be determined by simulating the pitch change of the tone. In this way, the target pictographic Braille corresponding to each target Chinese character can be divided into four parts: target pictographic Braille, target initial Braille, target final Braille, and target tone Braille.

[0125] Furthermore, in order to facilitate the blind person to input the target pictographic Braille, the target initial consonant pictographic Braille, the target final consonant pictographic Braille, and the target tone pictographic Braille to form the target pictographic Chinese character corresponding to the target Chinese character in a left-to-right order (or other orders such as from right to left), the target pictographic Braille, the target initial consonant pictographic Braille, the target final consonant pictographic Braille, and the target tone pictographic Braille can be mapped to the corresponding pictographic key positions, initial consonant key positions, final consonant key positions, and tone key positions of the input device according to different key structures of the input device. This allows the blind person to input the target pictographic Chinese character Braille more conveniently and accurately by triggering these key positions of the input device.

[0126] It should be noted that the reason why the present application proposes first determining the target pictogram and target Chinese phonetic notation (target initial consonant, target final consonant and target tone) corresponding to the target Chinese character, and then mapping the target pictogram Braille corresponding to the target pictogram, as well as the target pictogram Braille, target initial consonant Braille, target final consonant Braille and target tone Braille corresponding to each of the target initial consonant, target final consonant and target tone to the corresponding pictogram key position, initial consonant key position, final consonant key position and tone key position in the input device for subsequent target phono-phonetic Chinese character Braille input operation is mainly because the present application proposes a method of generating phono-phonetic Chinese character Braille based on the scientific principles of phono-phonetic Chinese characters, a phono-syllabic character generation method, a phono-phonetic character generation method and the Chinese Bagua sorting method of Braille Braille symbols, and inputting any phono-phonetic Chinese character Braille as the target phono-phonetic Chinese character Braille corresponding to the target Chinese character, which can not only make it easier for blind people to learn Braille, but also enable them to input Braille more quickly and accurately through the input device.

[0127] Next, this application will introduce in detail the scientific principles of phono-phonetic Chinese characters, the method for generating phono-syllabic characters, the method for generating phono-phonetic characters, and the Chinese Bagua sorting method of Braille symbols:

[0128] (1) Scientific Principles of Chinese Characters with Phonology and Phonetics

[0129] The world is made up of the movement of various objects, all of which are motion vectors relative to a reference object. By observing the movement of objects and simulating and representing them mentally, verbally, and in writing, monosyllabic Chinese and its phonetic characters were invented. Therefore, the movement of objects is the root of Chinese semantics, pronunciation, and writing. The scientific principles of phonetic characters are shown in Table 1 below:

[0130]

[0131] Table 1

[0132] Among them, single-syllable Chinese is a single-syllable language composed of initials, finals, and tones. Initials simulate the representation of object mass (for example, d and m can respectively represent a point and a surface to reflect a small range of the tip of the tongue and a large range of the lips, etc.), finals simulate the representation of motion vectors (such as moving inward, downward, outward, etc.), and tones simulate the representation of motion speed. Single-syllable Chinese is a lip-gesture spelling and meaning pinyin language, a physical Chinese that simulates the motion of objects, and also a relatively scientific language.

[0133] Shape-sound Chinese characters: Among Chinese characters, pictographs, ideographs, associative compounds, etc. are shape-sound Chinese characters formed by superimposing shape symbols and sound symbols, and phonetic compounds, borrowed characters, transferred characters, etc. are shape-sound Chinese characters formed by combining shape symbols and sound symbols. Shape symbols are object pictorial symbols, which are the basic symbols of Chinese characters, representing reference objects and moving objects, and representing the auxiliary semantics of Chinese. Sound symbols are Chinese phonetic symbols, which are important symbols of Chinese characters, representing object mass and motion vectors, and representing the main semantics and pronunciation of Chinese. Shape-sound Chinese characters are pictorial, ideographic, and phonetic characters, physical Chinese characters that simulate the motion of objects, and also relatively scientific characters.

[0134] (2) Methods for generating shape-syllable characters and shape-pinyin characters

[0135] Compared with other phonetic writing systems (including syllable writing systems and pinyin writing systems), shape-sound Chinese characters are self-originated characters tailored for single-syllable Chinese. They are shape-sound characters (including shape-syllable characters and shape-pinyin characters) formed by combining shape symbols and sound symbols (including syllables and pinyin), and have Chinese characteristics such as shape symbols, sound symbols, pictorial nature, square shape, and periodicity.

[0136] It can be understood that pictographic Chinese characters such as pictographs, ideographs, and associative compounds are shape-syllable characters formed by superimposing shape symbols and Chinese syllable symbols, and pictographic Chinese characters such as phonetic compounds, borrowed characters, and transferred characters are shape-syllable characters formed by combining shape symbols and Chinese syllable symbols. For example, the pictograph "wood" is a shape-syllable character formed by superimposing the shape symbol "wood" and the syllable "wood = mù". The ideograph "root" is a shape-syllable character formed by superimposing the shape symbol "wood\one" and the syllable "root = běn". The associative compound "forest" is a shape-syllable character formed by superimposing the shape symbol "wood\wood" and the syllable "forest = lín". The phonetic compound "wash" is a shape-syllable character formed by combining the shape symbol "氵" and the syllable "wood = mù". The phonetic compound "stupid" is a shape-syllable character formed by combining the shape symbol "bamboo" and the syllable "root = běn". The phonetic compound "drench" is a shape-syllable character formed by combining the shape symbol "氵" and the syllable "forest = lín". Therefore, pictographic Chinese characters can be unified as shape-syllable characters.

[0137] According to the content recorded in the patent "CN2(01410109221.2 A Method for Inputting Shape-Pinyin Chinese Characters", with the development of the times, for the popularization of education and the progress of science, shape-sound Chinese characters are very likely to develop from shape-syllable characters to shape-pinyin characters, as shown in Table 2:

[0138]

[0139] Table 2

[0140] Among them, because Chinese phonetic symbols include pictographic Chinese syllable symbols and pictographic Chinese phonetic symbols, phonophonetic Chinese characters also have two corresponding generation methods: phono-syllabic characters and phono-phonetic characters. Phono-syllabic characters are pictographic Chinese characters composed of pictographic symbols and pictographic Chinese syllable symbols, which can be understood as the primary stage of phono-phonetic Chinese characters. Phono-phonetic characters are pictographic characters composed of pictographic symbols and pictographic Chinese phonetic symbols, which are the advanced stage of phono-phonetic Chinese characters. Inheriting the scientific principles of phono-phonetic Chinese characters and developing innovative technologies for phono-phonetic Chinese characters, phono-phonetic Chinese characters are more likely to develop from phono-syllabic characters to phono-phonetic characters, as shown in the example figure. Figure 2 shown.

[0141] Furthermore, a detailed comparison is made between phono-syllabic characters and phono-phonetic characters, and the comparison results are shown in Table 3 below:

[0142]

[0143] Table 3

[0144] As can be seen, phono-syllabic characters have 201 pictographic symbols and 1,325 pictographic phonetic symbols (i.e., pictographic Chinese syllable symbols). These characters are numerous, have complex strokes, are inaccurate in pronunciation, and have ambiguous meanings, making them difficult to learn and use. This results in people being unable to analyze and understand the four essential elements of Chinese characters: the shape symbol, initial consonant, final vowel, and tone. When reading unfamiliar characters, they are unable to pronounce them, and when hearing new words, they cannot write them, forcing them to memorize phono-syllabic characters by rote. Therefore, phono-syllabic characters are pictographic Chinese characters, representing the early stages of phono-phonetic Chinese characters. They are relatively difficult to learn and are not conducive to learning Chinese.

[0145] Phonophonetic characters, on the other hand, only have 80 pictographic symbols and 31 pictographic phonetic symbols (i.e., pictographic phonetic symbols: initials and vowels). These are relatively few in number, have simple strokes, accurately represent sounds, clearly convey meaning, and are easy to learn and use. This allows people to analyze and understand the four elements of Chinese characters: shape symbols, initials, finals, and tones. They can pronounce new words when they read them, write them when they hear them, and actively apply phonophonetic characters. Therefore, phonophonetic characters are pictographic symbols and represent an advanced stage of phonophonetic Chinese characters. Compared to phono-syllabary characters, they are easier to learn and are more conducive to learning Chinese.

[0146] (3) Chinese Bagua Ordering Method of Braille Symbols

[0147] The six-dot Braille system, created by Blair, is designed for blind people to read and write. Each square has a left column and a right column. The left column, from top to bottom, is called 1, 2, and 3 (equivalent to the left trigrams), while the right column, from top to bottom, is called 4, 5, and 6 (equivalent to the right trigrams). Each dot has a dotless (equivalent to a negative dot 0) and a raised dot (equivalent to a positive dot 1). The number of raised dots and their arrangement create 64 Braille symbols (equivalent to the 64 trigrams), representing all of human scientific knowledge.

[0148] However, there are only 64 Braille symbols, which are far from meeting the needs of the above-mentioned picto-syllabic character generation method. It can only meet the needs of the pictophonetic character generation method, and correspondingly generate pictophonetic Braille spliced ​​by pictographic Braille and Chinese pictographic Braille (initial Braille, final Braille and tone Braille).

[0149] Mathematically speaking, the Braille symbol ordering system uses bases 2, 4, 8, 16, 32, and 64. However, the internationally accepted Braille symbol ordering system, as shown in Table 4 below, is a chaotic system. It uses a base 10 system, which is inconsistent with the computer system. As a result, rows 5, 6, and 7 cannot follow the order of rows 1, 2, 3, and 4, resulting in unclear logic, uneven arrangement, and asymmetry.

[0150]

[0151] Table 4

[0152] Therefore, the Chinese Braille symbols created according to the "International Common Ordering Method of Braille Symbols" such as the current Chinese Braille, Chinese double-pinyin Braille, Chinese general Braille or semantic phonetic Braille can be composed of three parts: initial consonant symbol Braille × final symbol Braille × tone symbol Braille.

[0153] These Chinese symbolic Braille scripts discard pictographic symbols and lack a corresponding correspondence with the pictographic Chinese characters used by sighted people. This results in unclear meaning, forcing the blind to guess. Furthermore, these Braille scripts forgo pictographic phonetic symbols and instead adopt Western symbolic Braille, rather than inventing Chinese pictographic Braille. This results in numerous and chaotic dots, lacking sound and meaning, making them difficult to learn, use, read, and write, requiring rote memorization. Furthermore, the omission of tones results in inaccurate phonetic representation, forcing the blind to guess. Furthermore, the presence of spaces to separate words wastes space and fails to meet the needs of the blind. This forces the blind to rely on rote memorization of Chinese symbolic Braille, while making it incomprehensible even to sighted people.

[0154] Therefore, in order to generate Braille that is easier to learn and use, the present application improves the internationally accepted Braille symbol sorting method and proposes a Chinese Bagua sorting method for Braille Braille symbols, as shown in Table 5 below:

[0155]

[0156] Table 5

[0157] Among them, the meanings of the Bagua symbols are as follows:

[0158] Yin -- Yang -- Kun Gen Kan Xun Zhen Li Dui Qian

[0159] It can be seen that the Chinese Bagua sorting method of Braille symbols shown in Table 5 is a left - right symmetric sorting method, adopting octal, with clear logic, neat arrangement, uniform upper - lower and left - right symmetry.

[0160] Based on this, this application proposes a method for generating form - sound Chinese character Braille that is more convenient for the blind to learn and use (input, reading, etc.) according to the scientific principles of form - sound Chinese characters, the method of generating form - syllable characters, the method of generating form - pinyin characters, and the Chinese Bagua sorting method of Braille symbols.

[0161] Among them, form - sound Chinese character Braille is composed of form - symbol Braille and Chinese pinyin Braille. Form - symbol Braille includes form - symbol pictographic Braille and form - symbol notational Braille. Chinese pinyin Braille includes Chinese pictographic Braille and Chinese notational Braille. Chinese pictographic Braille is composed of initial - consonant pictographic Braille, final - vowel pictographic Braille, and tone pictographic Braille. Form - sound Chinese character Braille inherits form - sound Chinese characters, does not require guessing pronunciation or meaning, does not require blank - space word - segmentation, and is easy to learn and use.

[0162] This method uses form - symbol pictographic Braille and Chinese pictographic Braille to form form - sound Chinese character Braille. Among them, form - symbol pictographic Braille is located on the left part of the corresponding form - sound Chinese character Braille, and Chinese pictographic Braille is located on the right part of the corresponding form - sound Chinese character Braille. And the initial - consonant pictographic Braille, final - vowel pictographic Braille, and tone pictographic Braille are combined to form Chinese pictographic Braille. Among them, the initial - consonant pictographic Braille is located on the left part of the corresponding Chinese pictographic Braille, the final - vowel pictographic Braille is located in the middle part of the corresponding Chinese pictographic Braille, and the tone pictographic Braille is located on the right part of the corresponding Chinese pictographic Braille. Furthermore, in the order from left to right, form - sound Chinese character Braille can be formed by the Braille of each part corresponding to form - symbol pictographic Braille, initial - consonant pictographic Braille, final - vowel pictographic Braille, and tone pictographic Braille. As Figure 3 shown, the Chinese character corresponding to this form - sound Chinese character Braille is "blind". Among them, the larger black dot "●" represents a raised dot, and the smaller black dot "·" represents no dot. For a detailed explanation, please refer to the subsequent embodiment introduction.

[0163] As can be seen, phonetic Braille inherits the pictographic and phonetic elements. Like Pinyin, it accurately represents pronunciation, eliminating the need for guessing. It also inherits the characteristics of phonetic Chinese characters, with unified glyphs and a complete range of phono-semantic and rhyme tones, eliminating the need for abbreviations or guessing pronunciation and meaning. There are no gaps between characters, no spaces between characters, and no need for word separations. It is concise, information-rich, and easy to learn, use, read, and write. This makes phonetic Braille easier to learn for the blind and easier for sighted people to understand. It can even be analyzed and processed using artificial intelligence algorithms.

[0164] Example: Braille with phonetic Chinese characters For example, a larger black dot represents a raised dot, and a smaller black dot represents no dot. Directly represents the mouth, Chinese pictographic Braille is Directly indicates the movement of air into the mouth. In other words, the phonetic Chinese character Braille There are both Objects, and air moving into the mouth Therefore, phonetic Chinese Braille is an animated text that has both objects and movements, which makes it easier for blind people to learn and use (input, reading, etc.), and also easier for sighted people to understand. It can even be further analyzed and processed through artificial intelligence algorithms to expand the application of Braille.

[0165] Therefore, in order to facilitate the user to input the target phonetic Chinese character Braille corresponding to the target Chinese character more conveniently and accurately through the input device, first, the target pictographic Braille can be set to the left of the target phonetic Chinese character Braille corresponding to the target Chinese character to be input, and the target Chinese pinyin pictographic Braille can be set to the right of the target phonetic Chinese character Braille corresponding to the target Chinese character to be input. Then, in order from left to right, the target initial consonant pictographic Braille can be set to the left of the target Chinese character Braille; the target final pictographic Braille can be set to the middle of the target Chinese character Braille; and the target tone pictographic Braille can be set to the right of the target Chinese character Braille. In this way, the target phonetic Chinese character Braille corresponding to the target Chinese character can be generated and input by executing the subsequent step S103, which is composed of the braille corresponding to the target pictographic Braille, the target initial consonant pictographic Braille, the target final pictographic Braille, and the target tone pictographic Braille.

[0166] Next, this application will introduce in detail the Braille corresponding to each of the target pictographic Braille, the target initial Braille, the target final Braille and the target tone Braille.

[0167] (1) Target Pictogram Braille

[0168] It should be noted that the world is composed of various substances, and an object refers to all tangible substances objectively existing in nature. Nature is composed of two types of objects: living and non-living. Among them, living objects, that is, objects with metabolism, are called organisms. For example: cells, viruses, microorganisms, plants, animals, humans, families, societies, etc. Non-living objects are called non-organisms. For example: the sun, the moon, fire, light, clouds, rain, air, water, soil, stones, gold, mountains, houses, doors, containers, cities, boats, cars, knives, tools, fibers, cotton cloth, etc.

[0169] Based on this, an optional implementation is that the target ideogram pictographic Braille can be biological ideogram pictographic Braille or non-biological ideogram pictographic Braille. Among them, biological ideogram pictographic Braille can include but is not limited to human figure ideogram pictographic Braille, organ figure ideogram pictographic Braille, animal figure ideogram pictographic Braille, and plant figure ideogram pictographic Braille; while non-biological ideogram pictographic Braille can include but is not limited to form ideogram pictographic Braille, compound ideogram pictographic Braille, curved ideogram pictographic Braille, and straight ideogram pictographic Braille. That is, non-biological ideogram pictographic Braille includes but is not limited to solids, liquids, gases, and the Braille corresponding to objects that are not naturally formed and created according to social and cultural development. Specifically, the ideogram pictographic Braille classification table is as shown in Table 6 below:

[0170]

[0171] Table 6

[0172] Among them, it should be noted that this application selects 64 relatively common ideograms (i.e., the radicals of Chinese characters), and constructs the ideogram pictographic Braille classification table (the corresponding relationship between each radical of Chinese characters and its corresponding one-sided Braille) shown in Table 6 according to the principle of symbol uniqueness and as similar to the actual object as possible. Among them, the larger black dots in each one-sided Braille represent raised dots, and the smaller black dots represent no dots. For example, taking the organ ideogram pictographic "eye" as an example, its corresponding ideogram pictographic Braille is a one-sided Braille similar to the position of the eyes on the face.

[0173] It can be understood that any ideogram pictographic Braille in Table 6 above can be used as the target ideogram pictographic Braille to generate and input the target ideogram phonetic Chinese Braille through subsequent steps.

[0174] (2) Target initial pictographic Braille

[0175] It should be noted that in this embodiment, for Chinese pictographic Braille, this application uses 31 pictographic Brailles to replace 31 Chinese pinyin letters, and the initial pictographic Braille, final pictographic Braille, and tone pictographic Braille are combined from left to right to form Chinese pictographic Braille, as shown in Table 7 below:

[0176]

[0177] Table 7

[0178] It can be understood that the initial consonant pictographic Braille, final consonant pictographic Braille, and tone pictographic Braille shown as examples in Table 7 above can be used as target initial consonant pictographic Braille, target final consonant pictographic Braille, and target tone pictographic Braille, respectively, to be combined with the target pictographic Braille to generate and input the target phonetic Chinese character Braille through subsequent steps.

[0179] Among them, an optional implementation method is that the target initial consonant pictographic Braille can be a pictographic Braille that simulates the tongue and labial pronunciation position and pronunciation method when pronouncing the initial consonant, including but not limited to tongue tip initial consonant pictographic Braille, tongue blade initial consonant pictographic Braille, tongue blade initial consonant pictographic Braille, tongue front initial consonant pictographic Braille, tongue back initial consonant pictographic Braille, and lower lip initial consonant pictographic Braille. Among them, the pronunciation position is: the tip of the tongue is at the top, the tongue blade is at the middle, the tongue surface is at the bottom, and the labial surface is at the top and bottom, and is symmetrical. The pronunciation method is: the plosive sound point is on the left, the fricative sound point is on the right, and is symmetrical.

[0180] In this implementation, the target initial consonant pictographic Braille is determined as follows: first, according to the Bagua sorting method, the general order of Braille symbols is adjusted using the octal system to achieve vertical symmetry and left-right symmetry of the Braille symbols, as shown in Table 5 above. Then, according to the adjusted order of the Braille symbols, combined with the initial consonant periodic table, the target initial consonant pictographic Braille is constructed.

[0181] Among them, it should be noted that, because the movement of objects has a family-symmetrical and week-symmetrical periodic law, such as the Yin-Yang theory, the law of unity of opposites, the periodic law of chemical elements, etc., the Chinese language that simulates the movement of objects also has a corresponding family-symmetrical and week-symmetrical periodic law of Chinese phonetic symbols. Therefore, this application improves and integrates the "initial consonant matrix table", "final vowel periodic table" and "Chinese tone table" recorded in the existing patent "CN202010166030.5 Shape-Spelling Meaning Chinese Character Input Method and Electronic Device", and forms an initial consonant periodic table, a final vowel periodic table and a tone table, and arranges the three from left to right in the natural order of Chinese phonetic symbols (first sound, then rhyme, then tone) into a family-symmetrical and week-symmetrical Chinese phonetic symbol periodic table (including initial consonant periodic table, final vowel periodic table and tone table), as shown in Table 8 below:

[0182]

[0183] Table 8

[0184] Specifically, as shown in Table 9 below, in order to construct the target initial consonant pictographic Braille, the left column of the Braille corresponding to the target initial consonant pictographic Braille can be set to aspirated plosives, which are as follows from top to bottom: The upper and lower parts are symmetrical; the right column is designed as fricative sounds, from top to bottom: Symmetrical from top to bottom and from left to right.

[0185] Secondly, add the midpoint Design the left column as airless plosives, from top to bottom: Symmetrical top and bottom; add midpoint The right column is designed as nasals and semivowels, from top to bottom: Symmetrical from top to bottom and from left to right.

[0186]

[0187] Table 9

[0188] In this way, the target initial consonant pictographic Braille including the tongue tip initial consonant pictographic Braille, the tongue blade front initial consonant pictographic Braille, the tongue blade back initial consonant pictographic Braille, the tongue front initial consonant pictographic Braille, the tongue surface back initial consonant pictographic Braille and the lower lip initial consonant pictographic Braille can be formed according to Table 9, which is specifically expressed as follows:

[0189] The pictographic braille of the tip of the tongue initials includes

[0190] The lingual initials pictographic Braille include

[0191] Post-lingual initial pictographic Braille includes

[0192] The pictographic braille characters for the front consonants of the tongue include

[0193] The pictographic braille characters for postlingual initials include

[0194] The lower labial consonant pictographic braille includes

[0195] In each Braille square, the larger black dot represents a convex dot, and the smaller black dot represents no dot.

[0196] (3) Target vowel pictographic Braille

[0197] An optional implementation method is that the target vowel pictographic braille can be a pictographic braille that simulates the tongue and lip movement trajectory and movement direction when pronouncing the vowel, wherein, in the braille corresponding to the target vowel pictographic braille, the initial dot is at the top, the nucleus dot is in the middle, and the final dot is at the bottom, and the upper and lower parts are symmetrical. The weak dot is at the left, and the strong dot is at the right, and the left and right parts are symmetrical. The target vowel pictographic braille can include but is not limited to the lower inner vowel pictographic braille, the outer lower inner vowel pictographic braille, the inner lower vowel pictographic braille, the lower vowel pictographic braille, the outer lower vowel pictographic braille, the inner and outer lower vowel pictographic braille, the inner lower outer vowel pictographic braille, and the lower outer vowel pictographic braille.

[0198] In this implementation, the target final pictographic Braille is determined as follows: first, according to the Bagua sorting method, the general order of Braille symbols is adjusted using the octal system to achieve vertical symmetry and left-right symmetry of the Braille symbols, as shown in Table 5 above. Then, according to the adjusted order of the Braille symbols, combined with the final periodic table (see Table 8 above), the target final pictographic Braille is constructed.

[0199] Specifically, as shown in Table 10 below, in order to construct the target vowel pictographic Braille, the positions of the rhyme head, rhyme body and rhyme tail mentioned in Table 7 above can be set first. For example, from top to bottom, they are the rhyme head, rhyme body and rhyme tail. rhyme belly rhyme ending Symmetrical from top to bottom and from left to right.

[0200]

[0201] Table 10

[0202] Then, according to the vowel periodic table shown in Table 8 above, all vowels are formed by combining the initial vowel, the main vowel and the final vowel: The larger black dots in each square of Braille represent raised dots, while the smaller black dots represent no dots.

[0203] In this way, target vowel pictographic braille including lower inner vowel pictographic braille, outer lower inner vowel pictographic braille, inner lower vowel pictographic braille, lower vowel pictographic braille, outer lower vowel pictographic braille, inner and outer lower vowel pictographic braille, inner lower outer vowel pictographic braille and lower outer vowel pictographic braille can be formed, which is specifically expressed as follows:

[0204] The lower inner vowel pictographic braille includes

[0205] The pictographic braille of the outer, lower and inner vowels includes

[0206] The inner and lower vowels of Braille include

[0207] The lower vowel pictographic braille includes

[0208] The pictographic braille of the outer and lower vowels includes

[0209] The pictographic braille of inner and outer vowels includes

[0210] The inner, lower and outer vowels of Braille include

[0211] The lower external vowel pictographic braille includes

[0212] These pictographic Braille characters of the finals not only have the advantages of internal symmetry, external symmetry, lower symmetry and upper symmetry, but also have the advantages of internal and external symmetry, lower and upper symmetry and central symmetry.

[0213] (4) Target Tone Pictographic Braille

[0214] In an optional implementation, the target tone pictographic Braille may be a pictographic Braille with onomatopoeic pitch changes, specifically including a first tone pictographic Braille with a yinping tone, a second tone pictographic Braille with a yangping tone, a third tone pictographic Braille with a shangsheng tone, and a fourth tone pictographic Braille with a qusheng tone.

[0215] Specifically, as shown in Table 11 below, in the Braille text corresponding to the target tone pictographic Braille, the high-tone dot can be set at the top, the middle-tone dot in the middle, and the low-tone dot at the bottom, with the top and bottom being evenly spaced. The tone dot is on the left, and the interval dot is on the right. Then, the right column is designed as the interval column. The left column is designed as the tone column, which is as follows from top to bottom: Yinping, Yinping, and Yinping. Hinata rising tone departing tone softly Symmetrical from top to bottom.

[0216]

[0217] Table 11

[0218] It can be seen that the target tone pictographic Braille can include the first tone pictographic Braille yinping Second tone pictographic braille Yangping The third tone of the pictographic braille rising tone Fourth tone pictographic braille falling tone Fifth tone pictographic braille light tone In each Braille square, the larger black dot represents a convex dot, and the smaller black dot represents no dot.

[0219] It should be noted that tones play a role in distinguishing meaning in Chinese syllables. For example, although the four words "unemployed," "real estate," "starting a business," and "career" have the same initial and final consonants, their different tones make them distinct as completely different words. Therefore, this application proposes to include target tonal pictographic Braille as part of the target phonetic Braille, which will also facilitate users' understanding, learning, and use of Braille.

[0220] In addition, it should be noted that since Chinese pictographic braille is composed of the corresponding braille characters for initial consonants, final consonants, and tones, the pictographic braille for initial consonants is on the left, the pictographic braille for final consonants is in the middle, and the pictographic braille for tones is on the right. For example: Then, based on the contents of Table 8 above, the Chinese Pinyin Braille periodic table composed of the initial consonant pictographic Braille periodic table, the final consonant pictographic Braille periodic table, and the tone pictographic Braille periodic table can be determined, as shown in Table 12 below:

[0221]

[0222] Table 12

[0223] In Table 12, the larger black dot in each Braille square represents a convex dot, and the smaller black dot represents no dot.

[0224] In this way, according to the scientific principles of phonophonetic Chinese characters, the method for generating phono-syllabary characters, the method for generating phono-phonetic characters, and the Chinese Bagua sorting method of Braille symbols, phonophonetic Chinese characters can be generated that are easier for blind people to learn and use. Among them, the pictographic braille of the phonophonetic Chinese characters is on the left side of the phonophonetic Chinese characters, and the Chinese pictographic braille is on the right side of the phonophonetic Chinese characters. In addition, the pictographic braille of the initial consonant in the Chinese pictographic braille is located on the left side, the pictographic braille of the final vowel is located in the middle, and the pictographic braille of the tone is located on the right side. Then, in order from left to right, a phonophonetic Chinese characters braille composed of the braille corresponding to the pictographic braille of the phonophonetic characters, the pictographic braille of the initial consonant, the pictographic braille of the final vowel, and the pictographic braille of the tone can be formed, with clear form and sound and neat arrangement. For example: Furthermore, a pictographic Chinese character Braille periodic table can be formed by combining the pictographic Braille classification table and the Chinese pictographic Braille periodic table, as shown in Table 13 below:

[0225]

[0226] Table 13

[0227] It can be seen that in this embodiment, since the phonetic Chinese characters are composed of pictographic symbols and pictographic phonetic symbols, correspondingly, the phonetic Chinese character Braille is composed of pictographic Braille symbols and Chinese pictographic Braille, thereby ensuring that the phonetic Chinese character Braille (i.e., the target phonetic Chinese character Braille) is one-to-one corresponding to the phonetic Chinese characters.

[0228] It should be noted that, in order to facilitate the blind to input the target pictographic Braille, the target initial consonant pictographic Braille, the target final consonant pictographic Braille, and the target tone pictographic Braille corresponding to the target pictographic Braille, in order from left to right, the present application proposes that the target pictographic Braille, the target initial consonant pictographic Braille, the target final consonant pictographic Braille, and the target tone pictographic Braille can be pre-mapped to the corresponding pictographic key positions, initial consonant key positions, final consonant key positions, and tone key positions in the input device according to different key structures in the input device. This allows the blind to input the target pictographic Braille more conveniently and accurately by triggering these key positions in the input device.

[0229] Specifically, one possible implementation is that the input device (keyboard or screen) can contain 4 groups from left to right, such as Figure 3 The "Square" button shown below, such as Figure 4 As shown, each group of "square" keys contains 6 dots, which are used to form a 6-dot Braille. These four groups of "square" keys can be used to represent the target pictographic Braille, the target initial Braille, the target final Braille and the target tone Braille, respectively, from left to right, the pictographic key position, the initial consonant key position, the final key position and the tone key position of the Braille mapped to each side.

[0230] Another possible implementation is that the input device (keyboard or screen) can include a "square" consisting of 6 keys and 1 enter key, such as Figure 5 As shown, these six keys correspond to a six-dot Braille system, which can be used to respectively indicate the position of the pictographic key, the initial key, the final key, and the tone key to which the target pictographic Braille, the target initial Braille, the target final Braille, and the target tone Braille are mapped (i.e., the positions of these four keys can overlap), and the Enter key can be used to switch between different types of Braille.

[0231] Another possible implementation is that the input device (keyboard or screen) can include 64 different keys (i.e., the positions of the pictogram key, the initial consonant key, the final consonant key, and the tone key are all input areas composed of these 64 different keys), which are used to correspond to the 64 possible representation forms formed by convex dots and no dots in a 6-dot Braille system, and each 6-dot Braille system can be used to represent the Braille mapped to the target pictogram Braille, the target initial consonant Braille, the target final consonant Braille, and the target tone Braille. Switching between different types of Braille can be done using the Enter key or the Space bar, etc.

[0232] On this basis, the implementation process of "in response to the user's triggering operation on the pictogram key position and the pinyin key position in the input device, generating the target pictogram Braille and the target Chinese phonetic Braille in the target pictogram-phonetic Chinese character Braille corresponding to the target Chinese character, so as to realize the input of the target pictogram-phonetic Chinese character Braille" in the above step S102 can specifically include: in response to the user's triggering operation on the pictogram key position, the initial consonant key position, the final consonant key position and the tone key position in the input device, generating the target pictogram Braille, the target initial consonant pictogram Braille, the target final consonant pictogram Braille and the target tone pictogram Braille in the target pictogram-phonetic Chinese character Braille corresponding to the target Chinese character, so as to realize the input of the target pictogram-phonetic Chinese character Braille.

[0233] In this embodiment, after the target pictographic braille, target initial consonant pictographic braille, target final consonant pictographic braille, and target tone pictographic braille are respectively mapped to the corresponding pictographic key positions, initial consonant key positions, final consonant key positions, and tone key positions in the input device (keyboard or screen), the blind person can further input the target pictographic braille, target initial consonant pictographic braille, target final consonant pictographic braille, and target tone pictographic braille corresponding to each of the key positions in the input device mapped thereto, in order from left to right.

[0234] Furthermore, in response to the user's triggering operation on the corresponding pictographic symbol key position, initial consonant key position, final consonant key position and tone key position in the input device (keyboard or screen), the Braille corresponding to the target pictographic symbol pictographic Braille, target initial consonant pictographic Braille, target final consonant pictographic Braille and target tone pictographic Braille input by the user can be obtained. Then, the Braille corresponding to the target pictographic symbol pictographic Braille, target initial consonant pictographic Braille, target final consonant pictographic Braille and target tone pictographic Braille input by the user can be used in sequence from left to right to spell out the target pictographic and phonetic Chinese character Braille corresponding to the target Chinese character, so as to realize the input of the target pictographic and phonetic Chinese character Braille.

[0235] Furthermore, an optional implementation method is to display the input target phonetic-phonic Chinese Braille characters and / or target Chinese characters on a display device, that is, the target phonetic-phonic Chinese Braille characters and / or the target Chinese characters corresponding thereto can be displayed on a display device such as a computer display screen.

[0236] For example: Assume that the input device (keyboard or screen) contains 4 groups from left to right such as Figure 3The "square" keys shown below, wherein each group of "square" keys contains 6 dots, corresponding to forming a 6-dot Braille, when using these four groups of "square" keys to represent the target pictographic Braille, the target initial Braille, the target final Braille and the target tone Braille, respectively, the pictographic key position, the initial consonant key position, the final key position and the tone key position of the Braille where the target pictographic Braille is mapped. Figure 4 As shown, when the user clicks on different positions (representing convex dots) of the six dots in the four groups of "square" buttons in sequence, the Braille corresponding to the target pictographic symbol, the target initial consonant pictographic Braille, the target vowel pictographic Braille, and the target tone pictographic Braille can be input respectively. In response to these input operations of the user, the target pictographic symbol, the target initial consonant pictographic Braille, the target vowel pictographic Braille, and the target tone pictographic Braille can be obtained respectively to form the target phono-phonetic Chinese character Braille corresponding to the target Chinese character. The target phono-phonetic Chinese character Braille and / or the target Chinese character can be displayed on a display device (such as a computer display screen).

[0237] Alternatively, assume that the input device (keyboard or screen) includes a "square" consisting of 6 keys and 1 enter key, wherein these 6 keys form a 6-dot braille. Figure 5 As shown, first, when the user first clicks on the different positions of the 6 dots in the “square” button (representing convex dots) and then clicks the Enter button, it is equivalent to the user triggering the pictogram key position, and the Braille corresponding to the target pictogram Braille can be input. Then, when the user clicks on the different positions of the 6 dots in the “square” button again (representing convex dots) and then clicks the Enter button, it is equivalent to the user triggering the initial consonant key position, and the Braille corresponding to the target initial consonant pictogram Braille can be input. Then, when the user clicks on the different positions of the 6 dots in the “square” button again (representing convex dots) and then clicks the Enter button, it is equivalent to the user triggering the final vowel key position, and the Braille corresponding to the target final vowel pictogram Braille can be input. Furthermore, when the user clicks on different positions of the six dots in the "square" button (representing convex dots) again and then clicks the Enter button, it is equivalent to the user triggering the tone button position, and the Braille corresponding to the target tone pictographic Braille can be input. In response to these input operations of the user, the target pictographic Braille, the target initial Braille, the target final Braille, and the target tone pictographic Braille can be respectively obtained to form the target phonetic Braille corresponding to the target Chinese character. The target phonetic Braille and / or the target Chinese character can be displayed on a display device (such as a computer display screen).

[0238] Alternatively, assume that the input device (keyboard or screen) contains 64 different keys, and these 64 keys respectively correspond to 64 possible representations formed by raised dots and non-raised dots in a six-dot Braille. Thus, when the user first clicks on key A among these 64 keys and then clicks on the enter key or the space key, it is equivalent to the user triggering the position of the ideogram key, and one Braille corresponding to the target ideogram pictographic Braille represented by key A can be input. Then, when the user first clicks on key B among these 64 keys and then clicks on the enter key or the space key, it is equivalent to the user triggering the position of the initial consonant key, and one Braille corresponding to the target initial consonant pictographic Braille represented by key B can be input. Next, when the user first clicks on key C among these 64 keys and then clicks on the enter key or the space key, it is equivalent to the user triggering the position of the final key, and one Braille corresponding to the target final pictographic Braille represented by key C can be input. Then, when the user first clicks on key D among these 64 keys and then clicks on the enter key or the space key, it is equivalent to the user triggering the position of the tone key, and one Braille corresponding to the target tone pictographic Braille represented by key D can be input. In response to these input operations of the user, the target ideogram pictographic Braille, the target initial consonant pictographic Braille, the target final pictographic Braille, and the target tone pictographic Braille can be respectively obtained, which are used to form the target phonetic ideogram Braille corresponding to the target Chinese character. And the input target phonetic ideogram Braille and / or the target Chinese character can be displayed on a display device (such as a computer display screen).

[0239] For example: Assume that the target Chinese character to be input is "盲 (máng)". After determining that the corresponding target ideogram, target initial consonant, target final, and target tone are respectively "目", "m", "ang", and "the second toneˊ", the target ideogram pictographic Braille corresponding to the target initial consonant pictographic Braille corresponding to the target final pictographic Braille and the target tone pictographic Braille can be determined respectively. Then, in the order from left to right, the target ideogram pictographic Braille the target initial consonant pictographic Braille the target final pictographic Braille and the target tone pictographic Braille can be respectively mapped to the keys at the positions of the ideogram key, the initial consonant key, the final key, and the tone key that represent the four-direction Braille on the keyboard or screen. Then, in response to the user's triggering operation on these corresponding target keys on the keyboard or screen, the target ideogram pictographic Braille the target initial consonant pictographic Braille the target final pictographic Braille and the target tone pictographic Braille Their corresponding one-sided Braille characters are used to form the target form-sound Chinese Braille characters corresponding to the target Chinese character "盲". To achieve the target form-sound Chinese Braille characters input. And it can and / or the target Chinese character "盲" corresponding to it are displayed on the display screen.

[0240] In summary, a method for inputting form-sound Chinese Braille characters provided in this embodiment first maps the target form-sign Braille characters corresponding to the target form-signs of the target Chinese character to be input to the position of the form-sign keys on the input device after determining the target form-signs and the target Chinese pinyin corresponding to the target Chinese character; and maps the target Chinese pinyin Braille characters corresponding to the target Chinese pinyin to the position of the pinyin keys on the input device; where the target form-sign Braille characters are target form-sign pictographic Braille characters or target form-sign notation Braille characters; the target Chinese pinyin Braille characters are target Chinese pictographic Braille characters or target Chinese notation Braille characters; the target Chinese pinyin is used to represent the main semantics and pronunciation of the target Chinese character; then, in response to the user's triggering operations on the position of the form-sign keys and the position of the pinyin keys on the input device, the target form-sign Braille characters and the target Chinese pinyin Braille characters in the target form-sound Chinese Braille characters corresponding to the target Chinese character are generated to achieve the input of the target form-sound Chinese Braille characters.

[0241] It can be seen that since this application first determines the target form-sign pictographic Braille characters corresponding to the target form-signs of the target Chinese character to be input and the target Chinese pinyin Braille characters representing the main semantics and pronunciation of the target Chinese character, and then maps the target form-sign Braille characters and the target Chinese pinyin Braille characters to the position of the form-sign keys and the position of the pinyin keys on the input device respectively. In this way, the user only needs to trigger these key positions on the input device to input the target form-sound Chinese Braille characters corresponding to the target Chinese character composed of the target form-sign Braille characters and the target Chinese pinyin Braille characters. The target form-sound Chinese Braille characters input in this way inherit all the advantages of form-sound Chinese characters, with unified glyphs, complete form and sound, no need for abbreviation or simplification, no need to guess pronunciation or meaning; there is no gap between squares, no space between characters, no need for space word segmentation, short length, concentrated information, easy to learn and use, easy to read and write. It not only enables the blind to learn Braille more easily and input Braille more quickly and accurately, but also enables sighted people to understand Braille, further expanding the application scope of Braille.

[0242] Second embodiment

[0243] See Figure 6 , which is a schematic flowchart of a method for converting Chinese characters into Braille provided in this embodiment. The method includes the following steps:

[0244] S601: Perform image parsing on the image containing the target Chinese character to be converted to obtain the target shape elements and the target Chinese pronunciation of the target Chinese character.

[0245] In this embodiment, any text converted into corresponding Braille using the method provided in this embodiment is defined as the target Chinese character to be converted. To improve the conversion effect, this application first needs to obtain an image containing the target Chinese character to be converted. Moreover, this embodiment does not limit the type of the image. For example, the image can be a color image composed of the three primary colors of red (R), green (G), and blue (B), or a grayscale image. Furthermore, this application does not limit the specific content of the target Chinese character. For example, the target Chinese character can be "blind".

[0246] Then, an existing or future image parsing method can be used to perform image parsing on the image containing the target Chinese character to be converted to obtain the target shape elements of the target Chinese character and the target Chinese pronunciation representing the main semantics and phonetics of the target Chinese character.

[0247] S602: Based on the target shape element, according to the pre-set correspondence between the shape element and the pictographic Braille, obtain the target pictographic Braille corresponding to the target shape element; based on the target Chinese pronunciation, according to the pre-set correspondence between the pronunciation and the pronunciation method and pronunciation position, obtain the target Chinese phonetic Braille corresponding to the target Chinese pronunciation.

[0248] After obtaining the target shape element and target Chinese pronunciation of the target Chinese character through step S601, the target shape element corresponding to the target shape element can be further obtained according to the preset correspondence between the shape element and the shape Braille, and based on the target Chinese pronunciation, the target Chinese phonetic Braille corresponding to the target Chinese pronunciation can be obtained according to the preset correspondence between the pronunciation and the pronunciation method and pronunciation position, so as to execute the subsequent step S603.

[0249] The pictographic Braille corresponding to the target shape element of the target Chinese character is a pictographic Braille that simulates the shape of an object related to the target Chinese character. The pre-set shape elements (i.e., pictographic Braille), pictographic Braille, and corresponding relationships can all be stored in a coded form so that these codes can be called at any time to query the pictographic Braille. The shape elements (i.e., pictographic Braille), pictographic Braille, and corresponding relationships can be found in the detailed description of the "target pictographic Braille" in the first embodiment, and will not be repeated here.

[0250] Similarly, the target Chinese pronunciation can also include target initials, target finals, and target tones. The pre-set pronunciation and pronunciation mode, and the corresponding relationship between the pronunciation position can also be stored in a coded form, so that these codes can be called at any time to query the target Chinese Pinyin Braille. In addition, the pre-set pronunciation and pronunciation mode, and the corresponding relationship between the pronunciation position can refer to the detailed description of "target Chinese Pinyin (target initials, target finals, and target tones)" in the first embodiment, that is, the target initial Braille can be a Braille that simulates the tongue and lip pronunciation position and pronunciation method when pronouncing the target initial; the target final Braille can be a Braille that simulates the tongue and lip movement trajectory and movement direction when pronouncing the final; the target tone Braille can be a Braille that simulates the pitch change of the tone. Then, the target Chinese Pinyin Braille corresponding to the target Chinese pronunciation can be obtained.

[0251] S603: splicing the target pictographic Braille and the target Chinese phonetic Braille, and using the splicing result as the pictographic Braille converted from the target Chinese character.

[0252] After obtaining the target pictographic Braille corresponding to the target shape element and the target Chinese phonetic Braille corresponding to the target Chinese pronunciation through step S602, the target pictographic Braille and the target Chinese phonetic Braille can be further spliced ​​(the target pictographic Braille is on the left and the target Chinese phonetic Braille is on the right, or the target pictographic Braille is on the right and the target Chinese phonetic Braille is on the left), and the splicing result is used as the pictographic Braille converted from the target Chinese character.

[0253] In summary, the present embodiment provides a method for converting Chinese characters into Braille. By pre-setting the correspondence between shape elements (i.e., pictograms) and pictogram Braille, as well as the pre-set correspondence between pronunciation and pronunciation mode and pronunciation position, the target pictogram Braille corresponding to the target shape element and the target Chinese phonetic Braille corresponding to the target Chinese pronunciation can be quickly matched. The target pictogram Braille and the target Chinese phonetic Braille can then be used to form the pictogram-Chinese character Braille after the target Chinese character is converted, which can effectively improve the processing efficiency and accuracy of converting Chinese characters into Braille.

[0254] Third embodiment

[0255] See also Figure 7 , is a flow chart of a Braille display method provided in this embodiment, the method comprising the following steps:

[0256] S701: Recognize the target Chinese character to be displayed to obtain the target shape part and the target pinyin part of the target Chinese character.

[0257] In this embodiment, any text that is displayed in corresponding Braille using the method provided in this embodiment is defined as the target Chinese character to be displayed. In order to improve the display effect, this application first needs to use existing or future text recognition methods to identify the target Chinese character to be displayed, so as to obtain the target shape part of the target Chinese character and the target Chinese pinyin part representing the main semantics and pronunciation of the target Chinese character, so as to execute the subsequent step S702.

[0258] S702: Convert the target pictogram part of the target Chinese character into target pictogram Braille and add a pictogram mark to the target pictogram Braille; and convert the target Chinese phonetic symbol part of the target Chinese character into target Chinese phonetic symbol Braille and add a phonetic mark to the target Chinese phonetic symbol Braille.

[0259] After obtaining the target pictographic symbol portion and the target Chinese phonetic symbol portion of the target Chinese character in step S701, the target pictographic symbol portion of the target Chinese character can be further converted into target pictographic symbol Braille according to the pre-established correspondence between pictographic symbols and pictographic symbol Braille (refer to the detailed description of "pictographic symbol Braille" as shown in Table 6 in the first embodiment), and a unique pictographic symbol identifier can be added to the target pictographic symbol Braille.

[0260] Based on the correspondence between Chinese Pinyin and Chinese pictographic Braille (including initial consonant pictographic Braille, final consonant pictographic Braille, and tone pictographic Braille) (refer to the detailed description of initial consonant pictographic Braille, final consonant pictographic Braille, and tone pictographic Braille as shown in Tables 7, 9, and 10 in the first embodiment), the target Chinese Pinyin portion of the target Chinese character is converted into target Chinese Pinyin Braille, and a unique Pinyin identifier is added to the target Chinese Pinyin Braille to execute the subsequent step S703.

[0261] S703: Using the pre-constructed preset display area for pictographic Braille and the preset display area for phonetic Braille, based on the pictographic identifier of the target pictographic Braille and the phonetic identifier of the target Chinese phonetic Braille, the target pictographic Braille and the target Chinese phonetic Braille are filled into the corresponding preset display areas and displayed.

[0262] After the target pictogram part of the target Chinese character is converted into target pictogram Braille and a pictogram identifier is added to the target pictogram Braille through step S702; and the target Chinese phonetic symbol part of the target Chinese character is converted into target Chinese phonetic symbol Braille and a phonetic identifier is added to the target Chinese phonetic symbol Braille, the target pictogram Braille and the target Chinese phonetic symbol Braille can be filled into the corresponding preset display areas and displayed based on the unique pictogram identifier of the target pictogram Braille and the unique phonetic identifier of the target Chinese phonetic symbol Braille.

[0263] The specific location and range of the preset display area of ​​the pre-built Braille pictographic Braille and the preset display area of ​​the phonetic Braille are not limited, for example, they can be as follows: Figure 4 The four groups of "square" button position areas shown in the figure respectively represent the preset display area where the braille of the pictographic braille is mapped, the preset display area where the braille of the target initial consonant in the target Chinese phonetic braille is mapped, the preset display area where the braille of the target final vowel in the target Chinese phonetic braille is mapped, and the preset display area where the braille of the target tone pictographic braille is mapped. In this way, based on the unique pictographic identifier of the target pictographic braille and the unique phonetic identifier of the target Chinese phonetic braille, the target pictographic braille and the target Chinese phonetic braille corresponding to the identifier can be filled into the corresponding preset display area and displayed.

[0264] In summary, the present embodiment provides a Braille display method that utilizes pre-constructed preset display areas for pictographic Braille and phonetic Braille. Based on the unique pictographic identifier of the target pictographic Braille and the unique phonetic identifier of the target Chinese phonetic Braille, the target pictographic Braille and the target Chinese phonetic Braille can be accurately and conveniently filled into the corresponding preset display areas and displayed, thereby improving the Braille display effect, making it easier for blind people to learn Braille, and enabling sighted people to understand Braille, further expanding the application scope of Braille.

[0265] Fourth embodiment

[0266] See also Figure 8 , is a flow chart of a method for generating a Braille character library provided in this embodiment, the method comprising the following steps:

[0267] S801: Traverse the Chinese characters in the Chinese character library, and split the found target Chinese characters to obtain the target shape and target Chinese pinyin corresponding to the target Chinese characters.

[0268] In this embodiment, in order to accurately generate a Braille character library, it is first necessary to traverse all Chinese characters in the Chinese character library one by one. Every time a Chinese character is traversed, it can be used as the target Chinese character to be found, and the target Chinese character can be split using existing or future text splitting methods to obtain the target shape corresponding to the target Chinese character, as well as the target Chinese pinyin representing the main semantics and pronunciation of the target Chinese character, so as to execute the subsequent step S802.

[0269] S802: Determine whether there is a pictographic Braille corresponding to the target pictographic symbol, and whether there is a Chinese phonetic Braille corresponding to the target Chinese phonetic symbol.

[0270] After obtaining the target pictogram and target Chinese pinyin corresponding to the target Chinese character in step S801, it is further possible to determine whether there is a pictogram Braille corresponding to the target pictogram in the existing pictogram Braille (refer to the detailed description of the "pictogram Braille" as shown in Table 6 in the first embodiment), and to determine whether there is a Chinese pinyin Braille corresponding to the target Chinese pinyin in the existing Chinese pictogram Braille (refer to the detailed description of the "pictogram Braille" as shown in Table 6 in the first embodiment). If not, proceed to the subsequent step S803; if so, proceed to the subsequent step S804.

[0271] S803: If not, then based on the division of the preset pictographic Braille categories, a new pictographic Braille category is established for the target pictographic symbol, or a pictographic Braille corresponding to the target pictographic symbol is established in the existing preset pictographic Braille category, to complete the establishment of the mapping between the target pictographic symbol and the corresponding pictographic Braille; and based on the division of the preset Chinese Pinyin Braille categories, a new Chinese Pinyin Braille category is established for the target Chinese Pinyin Braille, or a Chinese Pinyin Braille corresponding to the target Chinese Pinyin is established in the existing preset Chinese Pinyin Braille category, to complete the establishment of the mapping between the target Chinese Pinyin and the corresponding Chinese Pinyin Braille; and the pictographic Braille corresponding to the target pictographic symbol and the Chinese Pinyin Braille corresponding to the target Chinese Pinyin are used to construct the target pictographic Braille corresponding to the target Chinese character.

[0272] S804: If yes, construct the target pictographic and phonetic Chinese character Braille corresponding to the target Chinese character by using the pictographic Braille corresponding to the target pictographic symbol and the Chinese phonetic Braille corresponding to the target Chinese phonetic.

[0273] S805: Determine whether the target phonetic Chinese Braille character has different characters from the existing phonetic Chinese Braille character. If not, readjust the mapping relationship between the target icon and the corresponding icon Braille character and / or readjust the mapping relationship between the target Chinese pinyin and the corresponding Chinese pinyin Braille character. If so, save the Braille character corresponding to the target phonetic Chinese Braille character in the Braille word library, and so on, until all Chinese characters in the Chinese character library are traversed and processed to generate a Braille word library.

[0274] After constructing the target phonetic Chinese character Braille corresponding to the target Chinese character through step S803 or S804, it is further possible to determine whether the target phonetic Chinese character Braille has different characters from the existing phonetic Chinese character Braille. For example, the code corresponding to the target phonetic Chinese character Braille can be matched with the code corresponding to the existing phonetic Chinese character Braille, such as performing similarity calculation, etc., to determine whether the target phonetic Chinese character Braille has the same code as the existing phonetic Chinese character Braille based on the matching result, for example, whether the similarity is 1.
