Description

Technical Field

[0001] This invention relates to the field of sketching technology, and in particular to an apparatus and method for Chinese input using novel syllable-based sketching symbols. Background Technology

[0002] Currently, the characters in my country's mainstream pinyin-based handwriting shorthand system are composed of initials and finals according to pinyin rules. This method of character construction is limited and difficult to simplify, affecting writing speed. It generally requires the use of abbreviations to speed up writing, which in turn makes translation and subsequent organization difficult. Syllable-based handwriting shorthand, on the other hand, lacks sufficient simplified characters to accommodate the numerous syllables of Chinese characters, so its development has been rare or has failed. However, this shorthand method does not have methodological limitations and has the potential to simplify characters. The drawback of speech-to-text technology is its susceptibility to network, power supply, environment, and sound source. Computer stenography is difficult to learn and master, and both are subject to security checks.

[0003] Regarding existing technologies that combine handwritten shorthand symbols with smart devices, such as Chinese Patent Publication No. CN106484133A, which discloses a method for Chinese input using handwritten shorthand symbols, this invention can be applied to Chinese input on various smart terminals, including mobile phones and tablets. Because it uses simple and standardized shorthand symbols, Chinese characters are input through the touch screen of a smartphone or tablet. The hand-drawn symbols are shorthand symbols, and the displayed characters are Chinese characters. Moreover, the internal encoding, shorthand symbols, pinyin, and Chinese characters are matched with each other, so it is simple, accurate, easy to learn, and easy to remember.

[0004] Handwritten shorthand does not have these drawbacks; it requires only paper and a pen, can be used anytime, and is extremely convenient, especially in recording thought processes, enabling speech-impaired individuals to communicate normally. However, due to the complexity of shorthand symbols and the slow recording speed, it is increasingly being ignored, while high-speed handwritten shorthand has a significant role to play. The complexity of shorthand symbols and the slow recording speed have been a major hurdle for shorthand practitioners for many years. Therefore, we propose a device and method for Chinese input using novel syllable-based shorthand symbols. Summary of the Invention

[0005] To meet the growing demand for high-speed shorthand, this invention focuses on simplifying shorthand symbols and pioneers an unprecedented "syllabic shorthand method that transforms 13 simplified symbols into 416 phonetic symbols while maintaining the original form." This method fundamentally simplifies shorthand symbols and then configures corresponding character writing and connection rules.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A device for Chinese input using novel syllable-based shorthand symbols includes a hardware module and a software module, wherein the hardware module includes: Handwriting acquisition unit: Employs an electromagnetic induction handwriting tablet or capacitive touchscreen, supporting pressure-sensitive recognition; Display unit: Divided into symbol writing area and candidate word display area, it displays the writing trajectory and recognition results in real time; Processing unit: Built-in symbol recognition algorithm and Chinese dictionary; Storage unit: stores symbol library, dictionary, and user input records; Communication unit: Supports USB or Bluetooth wireless connection to terminal devices for synchronized input results; The software module includes: Symbol acquisition module: Real-time acquisition of coordinates, time, and pressure sensitivity data of handwritten trajectories, filtering out accidental touches; Symbol recognition module: Based on morphological features and writing sequence, it extracts the curvature, length, and direction features of the trajectory and matches them with the symbol library; Sequence parsing module: used to identify, segment, and parse handwriting into corresponding shorthand symbols; Lexicon matching module: Matches the lexicon with the sequence of shorthand symbols to generate candidate words, and supports user habit learning and priority sorting of frequently used words; The results output module converts the selected candidate words into text or pinyin and outputs them to the terminal device.

[0007] Preferably, the input keys for the shorthand symbols include a case conversion key, character keys, writing direction keys, and character connection keys; The character key is: The writing direction keys are: The character connection key is: , , , .

[0008] Preferably, the symbol library is formed through the following steps: 13 simple symbols: Write it as a capital character, and it becomes one of 26 characters; These 26 characters are respectively... - Writing in four directions (flat top, vertical bottom) results in 104 different characters; Connect these 104 characters to the preceding character: ,"Leave": “External error”: "Internal error": If connected in four different ways, it becomes 416 characters; These 416 characters are configured into a shorthand symbol table, representing 416 Chinese syllables from high to low frequency. Each simplified symbol has 32 variations, but remains in its original form. The complexity of each character is comparable to that of the initial consonant symbols in the pinyin shorthand method.

[0009] Preferably, it also includes a method for simplifying shorthand symbols from 13 symbols to 416 sounds, 1 sound and 1 stroke, such as pressing 1 key, and the corresponding writing and connection rules.

[0010] Preferably, two symbols are connected together, and the relative distance between the two symbols is used to indicate the position of the following symbols that cannot be connected, so as to realize the horizontal writing connection position of characters.

[0011] Preferably, the 104 characters are "connected" to the preceding character: ,"Leave": “External error”: "Internal error": If the four-way concatenation is used to connect the characters, resulting in 416 characters, the last character of each of the four-way concatenation methods is... Take over.

[0012] Preferably, the 104 characters are "connected" to the preceding character: ,"Leave": “External error”: "Internal error": If the four characters are connected separately, it becomes 416 characters. The four-character connection method is called biting connection, which means the character is connected after the bit.

[0013] Preferably, the horizontal distance between the two symbols is Small symbol length, the stated The position is a high-frequency character, the The digit character is a low-frequency character.

[0014] Preferably, the method also includes using two connection methods, namely biting and following, to indicate the position of the following character. When the characters are written horizontally, two characters that cannot be connected are connected by following the method. The position of the following character is indicated by the horizontal distance between the near ends of the two characters, similar to the biting positioning method.

[0015] A method for Chinese input using novel syllable-based shorthand symbols, based on the aforementioned device, includes the following steps: Step 1, Symbol Writing: In the symbol writing area of ​​the handwriting collection unit, the user writes the shorthand symbols of the target words in sequence according to the new syllable-based shorthand symbol system; Step 2, Trajectory Acquisition: The symbol acquisition module acquires the trajectory data for each symbol and discards invalid trajectories; Step 3, Symbol Recognition: The symbol recognition module extracts trajectory features, compares them with the symbol library, and outputs the recognized symbols. If recognition fails, it prompts the user to rewrite the symbols. Step 4, Sequence Analysis: The sequence analysis module analyzes the writing trajectory and generates a sequence of shorthand symbols based on the writing direction. Step 5, Lexicon Matching: The lexicon matching module calls the lexicon based on the sequence of shorthand symbols, sorts the candidate words by frequency of use and user habits, and displays them in the candidate word display area; Step Six: Result Confirmation and Output: The user selects the target candidate word by touch or button, and the result output module outputs it to the terminal device to complete the input.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This new method of Chinese input using syllable-based handwritten shorthand symbols integrates with a terminal device. By recording shorthand symbols through the device's handwriting tablet, it fundamentally simplifies shorthand symbols. Each syllable corresponds to one stroke, equivalent to full pinyin, making it easy to learn, translate, organize, and scan for documents. This will eliminate the slowness, abbreviations, and neglect of traditional handwritten shorthand. It will play a positive role in promoting education, cultural dissemination, international exchange, and improving the overall quality of the nation. Especially beneficial for education, it is ideal for millions of students in my country to take notes, offering both speed and document quality. It can be learned as early as fourth grade.

[0019] Figure 3 This is the general representation of characters in this invention. Detailed Implementation

[0020] In one embodiment, such as Figure 1 As shown, the device for Chinese input using novel syllable-based shorthand symbols includes a hardware module and a software module. The hardware module includes: Handwriting acquisition unit: adopts electromagnetic induction handwriting tablet (sampling rate 200 points / second, resolution 0.01mm) or capacitive touch screen, supports pressure-sensitive recognition (distinguishes the writing pressure of symbols to avoid accidental touch); Display unit: 3.5-10.1 inch LCD screen, divided into "symbol writing area" (occupying 60% of the screen) and "candidate word display area" (occupying 40% of the screen), which displays the writing trajectory and recognition results in real time; Processing unit: Employs an ARM Cortex-A7 processor (1.2GHz), with built-in symbol recognition algorithm and Chinese dictionary; Storage unit: 16GB Flash storage, storing symbol library, dictionary, and user input records; Communication unit: Supports USB or Bluetooth wireless connection to terminal devices for synchronized input results; The software modules include: Symbol acquisition module: Real-time acquisition of coordinates, time, and pressure sensitivity data of handwritten trajectories, filtering out accidental touch trajectories with a force of less than 50g; Symbol recognition module: Based on morphological features and writing sequence, it extracts the curvature, length and direction features of the trajectory and matches them with the symbol library (recognition accuracy ≥98%, recognition time <0.1s). Sequence parsing module: used to identify, segment, and parse handwriting into corresponding shorthand symbols; Lexicon matching module: Matches the lexicon with the sequence of shorthand symbols to generate candidate words, and supports user habit learning and priority sorting of frequently used words; The results output module converts the selected candidate words into text or pinyin and outputs them to the terminal device.

[0021] The method for Chinese input using the above-mentioned novel syllable-based shorthand symbols includes the following steps: Step 1, Symbol Writing: In the symbol writing area of ​​the handwriting collection unit, the user writes the shorthand symbols of the target words in sequence according to the new syllable-based shorthand symbol system; Step 2, Trajectory Acquisition: The symbol acquisition module acquires the trajectory data for each symbol and discards invalid trajectories; Step 3, Symbol Recognition: The symbol recognition module extracts trajectory features, compares them with the symbol library, and outputs the recognized symbols. If recognition fails, it prompts the user to rewrite the symbols. Step 4, Sequence Analysis: The sequence analysis module analyzes the writing trajectory and generates a sequence of shorthand symbols based on the writing direction. Step 5, Lexicon Matching: The lexicon matching module calls the lexicon based on the sequence of shorthand symbols, sorts the candidate words by frequency of use and user habits, and displays them in the candidate word display area; Step Six: Result Confirmation and Output: The user selects the target candidate word by touch or button, and the result output module outputs it to the terminal device to complete the input.

[0022] like Figures 2-3 As shown, in this embodiment, the input keys for shorthand symbols include a case conversion key, character keys, writing direction keys, and character connection keys; The character keys are: The writing arrow keys are: The character concatenation key is: , , , .

[0023] The specific methods are as follows: (1) 13 simplified symbols from simple to complex: (1) Write it as a character twice the size, resulting in 26 different characters; (2) Arrange these 26 characters according to... - Write in four directions: horizontal, vertical, and horizontal, to create 104 characters; (3) Connect these 104 characters to the preceding characters one by one, such as "Separation", such as "External errors", such as "Internal error", such as The concatenation symbols and their suffixes are respectively: The positions are connected, which means there are 416 characters; (4) Arrange these 416 characters in order from high frequency to low frequency to 416 Chinese syllables, and you will get a table of shorthand symbols from simple to complex and from high frequency to low frequency. The above shows that each simple symbol changes 32 sounds, but it is still the original form; the complexity of each character is equivalent to the initial consonant symbol of the pinyin shorthand method; when writing, you can connect the corresponding character and its connection method in the table with the previous symbol. The above 4 connection methods are called biting connection, which shows the connection position of the next symbol. The horizontal distance between the two symbols is Small charm length. Among them. This character is a high-frequency character and appears very frequently. The digit character is a low-frequency character, with an extremely low occurrence rate; this is a characteristic of Chinese characters. Character writing and connection rules: (1) Implement horizontal writing. The writing format is one line with only one middle line. The upper, lower, and upper vertical characters should be written on or below the middle line, and the end should be connected to the middle line. The upper and lower characters can be written on the middle line or the upper and lower vertical characters. All characters are two-character words. Multi-character words should be split into combinations of two-character words and single characters. It is stipulated that the end of the first character of the word should be connected to the middle line and connected to the last character of the word. A single character should be unbitten from the first character of the following word. It can be bitten or unbitten with the last character of the preceding word and connected to the nearest one. The first character of multiple single characters should be connected to the middle line. The following single characters can be bitten if they can. If they cannot be bitten, the nearby one should be bitten and follow or the upper one should be bitten and follow. The last single character should actively unbite from the first character of the following word. By connecting and writing in this way, the characters and single characters can be distinguished. Example of mixing characters and single characters: ① Two words with one single character, such as: ② Two words enclosing multiple single characters, such as: .

[0024] (2) Character Isolation and Alignment: When writing characters horizontally in four directions, some characters will inevitably be isolated. In this case, they can be aligned and connected for positioning. The rule is: two characters at a given position should be close together. If the end of the preceding character and the beginning of the following character are the nearest points, then the two nearest points should be vertically aligned. Position, pull one small character apart Position. Otherwise, the nearest two points with a horizontal distance of 1 unit are considered the rear prefecture. The rear residence is located two small mansions across the width of the central residence. Position. For example: For example: The misconnection representation is to use " "The 13 character categories were changed to " "Follow the example above, connecting the symbols as follows, with "+" for "W" and "-" for "N". This method can be used to connect any combination of uppercase and lowercase characters.

[0025] (3) Special cases for character connection: ① When two characters are not properly joined or adjacent, proximity is indicated by "+", and separation by 1 is indicated by "-". For example: ② When two symbols interlock, increasing the distance by two increments results in a "+", while increasing the distance by one increment still results in a "-". For example: When two symbols are mixed together, increasing the distance by 1 symbol results in a "+", while increasing the distance by 1 small symbol still results in a "-". For example: ③ When two symbols at a small angle cannot be staggered, a circle indicates "CW", and a cross indicates "CN". For example: ④ When the hook of a class symbol is misaligned with another symbol, it should be changed to "". "The sign is connected to the sign position after it," "CW" is the Chinese equivalent of "CW". "CN". For example: Create a 1-space gap, and then indicate the following character CN. If the other two characters are inconvenient to connect by misalignment, this method can be used as a reference.

[0026] (4) Positioning of paragraph beginning character and line break: ① The paragraph beginning character or line break is 1 large character from the left border, and the two large characters are respectively , If we transform the above example, they become CW and CN positions respectively. The newline character in the sentence and the left border "connecting" and "separating" are... , The position is then transformed into CW or CN positions, and newline characters and words cannot be split. ② The entire manuscript is connected as usual without interruption of sentences. ③ Repeated characters can be abbreviated, which will not be elaborated here; This syllable-based shorthand method, which uses 13 simplified symbols to represent 416 sounds while retaining their original forms, fundamentally simplifies shorthand symbols. Each sound corresponds to one stroke, equivalent to one keystroke, similar to full pinyin. It features standardized writing, clear distinction between word symbols and single characters, ease of learning and translation, and convenient subsequent organization. It also facilitates computer scanning of documents, making traditional shorthand no longer slow, eliminating the need for abbreviations, and preventing its neglect. This will play a positive role in promoting education, cultural dissemination, international exchange, and improving the overall quality of the nation. In particular, it promotes education and is ideal for millions of students in my country to take notes quickly and efficiently, providing both speed and documentation. It can be learned as early as fourth grade, rapidly improving learning abilities and fostering high-quality talent.
