Description

Technical Field

[0001] The present invention relates to the technical fields of Chinese input methods for computing devices, Chinese input software and hardware, and more specifically to an optimized arrangement scheme for a Chinese pinyin keyboard. Background Art

[0002] As the demand for the application of Chinese language and Chinese culture in multiple fields and regions increases, users are increasingly demanding that Chinese input methods should be easier to use, more efficient, and more in line with natural language expression habits.

[0003] The Chinese input methods and input devices currently used on the market have the following problems: 1. In common pinyin input methods, for pinyin with tones, the vowels and tones are entered separately using multiple keys, which increases the duplication rate, makes input cumbersome, and does not represent a complete natural Chinese language expression, resulting in a poor user experience. 2. Among common pinyin input methods, some designate multiple initials and finals as dedicated keys or map them to English character keys, allowing users to input multiple initials and finals with one key, thereby reducing the duplication rate and increasing input speed. However, this can lead to problems such as difficulty in memorization, learning, and promotion for users. 3. Common input methods based on Chinese character radicals and glyph encoding have low duplication rates and fast input speeds, but they are difficult to memorize radicals and analyze glyphs, leading to problems such as difficulty in learning and promotion. 4. Common input methods based on Chinese character radicals and glyph encodings have little correlation between user input and text pronunciation, and do not conform to the natural language expression habits of Chinese. They are more suitable for professional and fast input scenarios, but not for general and daily input scenarios. 5. There is no similar input method or input device on the market that expands the unique characters and tone characters of Pinyin into special keys, optimizes the layout, and integrates the design of the standard QWERTY keyboard to reduce the duplication rate of Chinese character input and simulate the natural language expression of Chinese. The design eliminates redundancy to the greatest extent, making it easy for beginners to remember and also has complete Pinyin input and Chinese character input functions.

[0004] Specifically, Optimized Wubi font encoding method and keyboard, patent number: CN85100837A Method: Customize commonly used Chinese character radicals and map them to English character keys. At the same time, combine them with key input that represents information such as glyphs to reduce the duplication rate of Chinese character input and improve input speed. Disadvantages: Users will have greater difficulty in memorizing, splitting radicals, and analyzing glyphs, which will have a certain impact on learning and promotion.

[0005] Root encoding input method and device, patent number: CN1043210A Method: Customize commonly used Chinese character radicals and map them to English character keys. Combined with key input that represents glyph information, this reduces the duplication rate of Chinese character input and increases input speed. This is an improvement over earlier similar input methods, making radicals easier to remember and use. Disadvantages: There are still some difficulties for users to remember radicals and analyze character shapes, and the input is not related to the pronunciation of the text. It is not suitable for non-professional input scenarios, such as users' natural language expression habits during online chats and copywriting, which has a certain impact on usability and popularity.

[0006] Easy-to-learn and easy-to-remember double-pinyin scheme and keyboard, patent number: CN1126336A Method: Multiple initials and finals in Chinese Pinyin are mapped to English character keys, and auxiliary codes containing information such as character shape are combined to reduce the duplication rate of Chinese character input and improve input speed; Disadvantages: Users need to be proficient in memorizing the mapping from pinyin to English characters, which is somewhat difficult. In addition, the system does not take into account tones to reduce the duplication rate. Instead, it combines key input with information such as glyphs. Users need to consider information such as pronunciation and glyphs at the same time, which does not conform to the user's natural language expression habits. There are problems such as affecting usability and user experience.

[0007] A computer input keyboard for decomposing characters and pinyin and its input method, patent number: CN1127895A Method: Map multiple initials, finals and characters in Chinese Pinyin to English character keys to reduce the duplication rate and increase input speed; Disadvantages: Users need to memorize custom mappings, which is somewhat difficult. It does not take into account tones to reduce the repetition rate, does not conform to the user's natural language expression habits, and has problems such as affecting usability and user experience.

[0008] Computer Chinese input methods on the market: Some are based on the principle of full spelling input, and need to type single characters in Chinese pinyin one by one, and combine technologies such as character library retrieval and AI prediction to reduce the duplication rate. Some map multiple initials and finals in pinyin to English character keys, and combine auxiliary codes containing information such as glyphs to reduce the duplication rate of Chinese character input and increase input speed. Some customize character roots based on the splitting and analysis principles of Chinese character roots and glyphs, and map them to English character keys to reduce the duplication rate. In addition, there are other methods that take into account both pronunciation and glyph information to reduce the duplication rate in the form of composite encoding. In addition, there are input methods such as voice recognition and handwriting input recognition. Disadvantages: Although the full-pinyin input method can greatly reduce the duplication rate after combining with the enhanced algorithm, it will rely on the length of the text input to remove duplicates. For the input of shorter or uncommon text expressions, the duplication rate still has room for reduction because the tone is not taken into consideration. It also does not fully simulate the user's natural language expression, which has a certain impact on the user experience. In addition, input methods such as double-pinyin customize the mapping of multiple initials and finals in Chinese pinyin to English character keys to reduce the duplication rate. Therefore, there is a certain degree of learning and memory difficulty, which is not conducive to promotion. In addition, input methods based on the principles of splitting and analyzing radicals and glyphs have a lower duplication rate, but are more suitable for professional and fast input. In some scenarios, it is difficult for ordinary users to learn, remember and analyze, and the input is not related to voice, which does not conform to the natural language expression habits and has user experience problems. In addition, the input method that takes into account the pronunciation and shape of characters to reduce the duplication rate is also difficult to learn and use. It also does not conform to the natural language expression habits, is not easy to promote, and has a poor user experience. In addition, the voice recognition input method is easily disturbed by the background sound of the environment when in use, or is limited by the environment and cannot be used conveniently. There are also problems such as recognition accuracy. In addition, the handwriting input method has specific requirements for the input device, and the general text input speed is slow, which is only suitable for specific scenarios.
