Description

Technical Field

[0001] The present invention relates to the field of data processing technology, and in particular to a pinyin input device, a pinyin input method, and a computer program product. Background Art

[0002] With the widespread popularity of computers and mobile phones, the demand for Chinese character input is increasing. At present, there are many Chinese character input schemes for computers and mobile phones, among which Pinyin input method occupies a dominant position due to its large user base. Moreover, due to the continuous optimization of Pinyin input method in functions such as automatic word formation and long sentence input, the proportion of users who choose this input method continues to grow.

[0003] Among various pinyin input methods, Chinese character double pinyin can significantly reduce the number of keyboard taps compared to full pinyin, and because its syllables are clearly separated, there is no need to use the space bar to mark the end of a syllable, which undoubtedly improves operating efficiency and optimizes the computer's automatic word selection process. Its advantages are obvious.

[0004] The Shuangpin input technology solution is an optimization method based on the Pinyin input method. By mapping each initial consonant or final consonant containing multiple letters to a specific key, each sound can be typed with at most two keys. The following is a detailed introduction to the Shuangpin input technology solution: 1. Mapping of initials and finals: The double-pinyin scheme maps the initials and finals in Chinese Pinyin to a key, which greatly simplifies the input process. For example, in the natural code double-pinyin scheme, the initial consonant "zh" may be mapped to the "a" key, while the final "ang" may be mapped to the "s" key. Such mapping reduces the number of keystrokes required to enter a single character, thereby increasing the input speed.

[0005] 2. Diversity of schemes: There are many double spelling schemes currently, including but not limited to Natural Code, Sogou Double Pinyin, Microsoft Double Pinyin, Xiaohe Double Pinyin, Smart ABC, etc. Each scheme has its own unique mapping rules, and users can choose the double spelling scheme that suits them according to their own memory habits and typing habits.

[0006] 3. Customized Scheme: In addition to using the existing double-pinyin scheme, advanced users can also customize the double-pinyin mapping scheme through the settings function of the input method software. This provides more flexibility for users with special needs.

[0007] 4. Learning curve: For users who are new to Shuangpin input method, they need to go through a learning and adaptation process. Although there may be memory challenges in the early stage, with time and continuous practice, users will be able to master the selected Shuangpin scheme and achieve the effect of fast input.

[0008] In summary, the double-pinyin input technology solution effectively improves the input speed of Chinese characters by mapping initials and finals to specific keys. Its ease of learning and high customizability make it the preferred solution for many pinyin input method users. However, although the double-pinyin input solution has obvious advantages in improving typing speed, it also has some disadvantages that cannot be ignored. The following are the disadvantages of the existing double-pinyin input solution: 1. Too many letters: The double-pinyin input scheme requires at least 53 letters to cover all combinations of initials and finals, which exceeds the optimal value of 40 letters for phonetic characters, making it difficult to implement Latinized design. This excessive number of letters requires users to remember more mapping rules, increasing the learning cost.

[0009] 2. Heavy memory burden: Since the double-pinyin input scheme maps initials and finals to different letters, users need to remember these mapping relationships. For beginners, this may take some time to adapt and learn, especially when there are multiple double-pinyin schemes, each with different mapping rules, which increases the user's memory burden.

[0010] 3. Difficulty in customizing the scheme: Although some input method software allows users to customize the double-pinyin scheme, this can be a complicated process for non-technical users. Users need to understand how to set and adjust the mapping rules, which may be a technical barrier for some users.

[0011] 4. Input accuracy problem: The double-pinyin input scheme simplifies the input process, but it may also lead to reduced input accuracy. Since the information represented by each letter is more complex, users may make mistakes when inputting quickly. Summary of the invention

DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the solution of the present application, the following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0019] Figure 1A 1 is a schematic diagram of the structure of a pinyin input device according to an embodiment of the present application. As shown in FIG1 , the pinyin input device includes: A keyboard module, configured to have a mapping of first keys and key values, wherein the mapping of the first keys and key values ​​is used to configure a correspondence between an English letter set and the keys; An initial consonant module, which is configured to have a mapping of a second key and a key value, wherein the mapping of the second key and the key value is used to configure a correspondence between a first letter group defined in the English letter set and an initial consonant key value group and a key; The final module includes a single final unit, a basic final unit, and a derived final unit, wherein: The single vowel unit is configured to have a mapping of a third button and a key value, wherein the mapping of the third button and the key value is used for the corresponding relationship between the second letter group defined in the English alphabet set and the single vowel key value group and the button; The basic vowel unit is configured to have a mapping of a fourth key and a key value, wherein the mapping of the fourth key and the key value is used for a correspondence between a fourth letter group defined in the English letter set and a basic vowel key value group and a key; The derived final unit is configured to have a mapping of a fifth key and a key value, wherein the mapping of the fifth key and the key value is used for a corresponding relationship between a fifth letter combination defined in the English letter set and a derived final key value and a key; The syllable parsing module is used to capture the input sequence generated by triggering the keyboard, and parse the input sequence based on at least one of the mapping of the second key and the key value configured in the initial consonant module and the mapping of the third key and the key value configured in the final consonant module, the mapping of the fourth key and the key value, and the mapping of the fifth key and the key value, so as to determine the initial consonant and final consonant combination in the input sequence that satisfies the Chinese Pinyin rules, and output the word or phrase corresponding to the initial consonant and final consonant combination.

[0020] For this reason, the above-mentioned pinyin input device has the following technical advantages: 1. Flexible button mapping configuration to meet diverse needs 1. Mapping advantages of keyboard module The correspondence between the English letter set and the key is configured by mapping the first key and the key value, and different matching definition models are provided. For example, one model is to arrange the English letters in different rows of the keyboard in order according to different letter groups (such as the first letter group QWERTYUIOP, the second letter group ASDFGHJKL, and the third letter group ZXCVBNM) and assign keys to them respectively. Another model is to arrange some letters by sharing keys. This flexible mapping configuration method can adapt to the operating habits of different users for keyboard layout and the actual conditions of different devices (such as 26-key keyboards, 17-key keyboards, etc.), and provides a diverse basic framework for the subsequent mapping of initials and finals, which is convenient for users to choose and adjust according to their own preferences.

[0021] 2. Benefits of mapping initials and finals The initial consonant module and the final consonant module (including single final unit, basic final unit, and derived final unit) have their own corresponding key and key value mapping configurations. For different types of initial consonants and finals, targeted key associations can be made according to their characteristics, so that each sound can be mapped to a specific key in a relatively reasonable manner, making the best use of keyboard resources to achieve efficient pinyin input. For example, finals of different complexity and frequency of use (single finals, basic complex finals, and derived complex finals) have their own adaptive mapping rules, which take into account their own pronunciation composition characteristics and the convenience of keyboard operation, avoiding the confusion and inconvenience that may be caused by a unified mapping method.

[0022] 2. Improve input efficiency and accuracy 1. The role of mapping-based sequence parsing The syllable parsing module parses the input sequence generated by the keyboard trigger operation based on the key and key value mapping configured by each module, determines the combination of initials and finals that meets the Chinese Pinyin rules, and outputs the corresponding words or phrases. Since the previous modules have reasonably mapped the initials and finals to the keys, during the input process, the user performs key operations according to the corresponding mapping rules. The parsing module can accurately and quickly identify the user's intentions, convert the input sequence into the correct Pinyin combination, and then output the corresponding words. Compared with the traditional input method, it reduces the time cost of users having to frequently think about how to spell and choose the correct Pinyin when inputting, greatly improves the input efficiency, and also helps to reduce input errors caused by unskilled operation or complex input rules, and improves the accuracy of input.

[0023] 3. Reduce memory burden and learning cost 1. Regular vowel mapping rules help memory In the vowel module, except for the less frequently used "ü" which has a specific arrangement that is easy to remember (arranged on the B key), the positions of a, o, e, i, u, etc. on the original English keyboard remain basically unchanged; the basic complex vowels are arranged symmetrically on the specific keys in the middle row of letter keys (such as S, D, F, G, H, J, K, L keys corresponding to different basic complex vowels); derived complex vowels are arranged on their respective upper and lower adjacent key positions in a relatively regular manner based on their combination relationship with single vowels and basic complex vowels, and there is also a correlation between finger operations between many adjacent key positions (such as the same finger operation or adjacent finger operation). Such regular and highly correlated vowel mapping rules make it easy for users to remember the key positions corresponding to different vowels. Compared with the more difficult to remember vowel mapping in other double-pinyin input schemes, it significantly reduces the user's learning cost and memory burden, and is more conducive to users quickly getting started and mastering the use of the input device, thereby promoting the popularization and application of double-pinyin input.

[0024] 4. Wide applicability and operability 1. Can be used in combination with existing input methods The scheme of the pinyin input device has strong operability. It can be applied to some existing pinyin input methods, such as Baidu Pinyin Input Method, Microsoft Pinyin Input Method, etc. As long as the user customizes the double-pinyin key positions according to the present invention, Chinese input can be realized in actual application. This means that the user does not need to completely replace the new input method software, but can optimize the double-pinyin input function based on the familiar input method platform, making full use of the user's existing usage habits and software resources, further improving the acceptance and popularity of the technical solution in actual application, and facilitating more users to enjoy the input convenience brought by it.

[0025] 2. Adapt to different keyboard types Whether it is a common 26-key keyboard or a 17-key keyboard designed for mobile phone screens, they can be laid out and applied according to the corresponding key and key value mapping rules, so that the pinyin input device is not limited to a specific keyboard form and can be widely used in different device scenarios to meet users' needs for efficient and convenient pinyin input on a variety of devices.

[0026] Optionally, the mapping of the first key and the key value generates a configuration of a correspondence between an English letter set and the key according to the following matching definition model: The English letter set includes a first letter group, a second letter group, and a third letter group. The first letter group includes letters: QWERTYUIOP, the second letter group includes letters: ASDFGHJKL, and the third letter group includes letters: ZXCVBNM; Arrange the letters included in the first letter group: QWERTYUIOP in sequence from left to right on the first row of the keyboard and assign a key to each letter in QWERTYUIOP; Arrange the letters included in the second letter group: ASDFGHJKL in sequence from left to right on the second row of the keyboard and assign a key to each letter in ASDFGHJKL; The letters included in the third letter group: ZXCVBNM, are arranged in sequence from left to right on the second row of the keyboard and a key is assigned to each letter in ZXCVBNM.

[0027] To this end, the technical benefits of configuring the mapping between the first key and the key value according to the matching definition model are as follows: (1) Conforms to the conventional keyboard layout and is easy to use This method of arranging the English letter set in different rows of the keyboard according to the first letter group (QWERTYUIOP), the second letter group (ASDFGHJKL), and the third letter group (ZXCVBNM), and assigning a separate key to each letter, is highly consistent with our common standard keyboard layout. Most users have formed a deep understanding and operating habits of such basic letter distribution when using computer keyboards and other devices in daily life. For example, in the process of conventional text input and shortcut key operation, users have long been familiar with the position of letters on the keyboard. With such a mapping configuration, users do not need to spend a lot of time to re-adapt to a new and unfamiliar keyboard letter layout, and can quickly get started using the pinyin input device, which greatly reduces the learning cost and improves user acceptance.

[0028] (2) Orderly layout facilitates quick key location and improves input speed The letters in each letter group are arranged in order from left to right and the keys are assigned, so that the arrangement of the letters on the entire keyboard appears clear and orderly. When the user is performing pinyin input operations, he can quickly locate the keys corresponding to the required letters by relying on the muscle memory of the keyboard position accumulated in the past and the visual intuition. For example, when you want to enter the pinyin corresponding to the initial consonant starting with "Q", the user can rely on instinct to quickly find the "Q" key located on the leftmost position of the first row of the keyboard, without having to search in a messy or illogical layout. This saves time in finding keys during the input process, helps to improve the overall speed of pinyin input, and thus improves the efficiency of text input.

[0029] (3) Standardized layout facilitates memory and operation, and enhances input accuracy This layout is highly standardized and regular, and each letter has a fixed and clear position, which is very helpful for users to remember the key distribution of each letter. Compared with layouts with random letter mapping and no obvious rules, users are less likely to make input errors due to misremembering the key positions during use. At the same time, this orderly and standard layout also facilitates users to perform blind typing operations, further improving the accuracy of input. Because after users are familiar with the layout, they can rely on the touch of their fingers and muscle memory to accurately press the corresponding keys, reducing the possible misoperation caused by visual search and verification, making pinyin input more accurate and smooth, reducing the error correction process in the input process, and optimizing the entire input experience.

[0030] (4) Facilitates the formation of unified operating habits in different application scenarios Whether it is for text input tasks such as document editing, chatting, etc. on the computer, or used on other devices that support the pinyin input device and use a standard keyboard layout, the unified configuration of the correspondence between letters and keys allows users to maintain consistent operating habits in different application scenarios. This consistency helps users form stable input muscle memory. No matter when and where the input device is used, it can be efficiently input with the familiar key layout, avoiding operational troubles caused by large layout differences between different devices, and enhancing the versatility and convenience of the technical solution in multi-scenario applications.

[0031] Optionally, the mapping of the first key and the key value generates a configuration of a correspondence between an English letter set and the key according to the following matching definition model: The English letter set includes a first letter group, a second letter group, and a third letter group. The first letter group includes letters: QWERTYUIOP, the second letter group includes letters: ASDFGHJKL, and the third letter group includes letters: ZXCVBNM; Arrange the letters included in the first letter group: QWERTYUIOP in the first row of the keyboard from left to right, and in QWERTYUIOP, the letters QW share one key, the letter E is assigned one key, the letters RT share one key, the letters YU share one key, the letters I are assigned one key, and the letters OP share one key; Arrange the letters included in the second letter group: ASDFGHJKL in the second row of the keyboard from left to right, and in ASDFGHJKL, the letters AS share one key, the letter E is assigned one key, the letters DF share one key, the letters G are assigned one key, the letters H are assigned one key, the letters JK share one key, and the letter L is assigned one key; The letters included in the third letter group: ZXCVBNM, are arranged in sequence from left to right in the second row of the keyboard, and in ZXCVBNM, the letters ZX share a key, the letters CV share a key, the letter B is assigned a key, the letter N is assigned a key, and the letter M is assigned a key.

[0032] Therefore, the above-mentioned mapping configuration method of the first key and the key value has the following technical advantages: 1. Optimize keyboard space utilization and increase mapping possibilities By setting shared keys for some letters, the "space" available for mapping is expanded based on the limited number of keyboard keys. For example, shared keys are arranged for letter combinations such as QW, RT, YU, OP in the first letter group, and the corresponding letters in the second and third letter groups are shared, so that more mapping needs for different functions (such as initials, finals, etc.) can be accommodated without adding additional physical keys. This creates conditions for the subsequent more refined and diversified configuration of mapping relationships related to pinyin input, fully taps the potential utilization value of the keyboard, and makes complex mapping schemes that may have been difficult to achieve due to the limited number of keys feasible.

[0033] 2. Conform to finger operation habits and improve input efficiency This layout of shared keys takes into account the convenience and continuity of finger operation. For example, in daily typing, adjacent fingers often work together to operate some key combinations more smoothly. For example, after some letters are set as shared keys in QWERTYUIOP, when adjacent fingers operate the functions corresponding to these shared keys, the movements are more natural and smooth, reducing the situation where the fingers jump and move drastically on the keyboard. Similarly, the arrangement of shared keys for the second and third letter groups also follows the principle of coordination of finger operations. When users perform pinyin input operations, their fingers can trigger the corresponding keys with relatively comfortable and efficient movements, thereby speeding up the input rhythm and improving the overall input efficiency, especially in the case of long-term input, which can effectively reduce hand fatigue.

[0034] 3. Enhance key association memory and reduce learning cost The setting of shared keys integrates letters with related relationships together, making it easier for users to remember their corresponding functions and operating methods. Taking the first letter group as an example, when users remember arrangements such as QW sharing a key, they can understand and remember it as a whole. Compared with remembering the different mapping situations of each letter separately, this grouping memory method is more in line with human memory rules and easier to remember. For the key and key value mapping of each letter group in the entire English letter set, through this regular shared key configuration, a relatively systematic and logically coherent memory framework is formed, which helps users to become familiar with and master the correspondence between letters and keys in the input device more quickly, thereby reducing the cost of learning to use the pinyin input method.

[0035] 4. Facilitate the differentiation and combination of functions and adapt to diverse input needs By grouping letters in the form of shared keys, specific mapping functions such as initials and finals can be assigned to these grouped keys according to different input requirements and functional characteristics, so as to achieve more flexible functional differentiation and combination. For example, some shared key combinations may be more suitable for mapping initials and finals that are used more frequently or have strong associations, so that the corresponding keys can be triggered quickly and continuously during the input process to complete the pinyin input, while other letters with individually assigned keys can be used to map some special elements that require separate operations. This configuration method can better adapt to various pinyin input scenarios and users' personalized input habits, meet diverse input needs, and improve user experience.

[0036] 5. Improve the uniqueness of keyboard layout to avoid misoperation Different from the conventional layout where each letter occupies a key, this shared key layout is unique, allowing users to more clearly understand that they are using a specially designed pinyin input device during operation, reducing the possibility of misoperation due to confusion with conventional keyboard operation habits. Moreover, since the letter combination corresponding to each shared key is clearly specified, as long as the user is familiar with this layout rule, the corresponding operation can be performed accurately, further ensuring the accuracy of input. Even in the case of fast input, it is not easy to make input errors due to accidentally touching other keys.

[0037] Optionally, the mapping of the second key and the key value generates a configuration of a correspondence between an English letter set and the key according to the following matching definition model: The mapping between the first key and the key value is reused to generate the correspondence between the first letter group defined in the English letter set and the initial consonant key value group and the key, and the first letter group includes the following letters: QWERTYUIOPASDFGHJKLZXCVBNM.

[0038] The technical advantages of the configuration method of "reusing the mapping of the first key and key value to generate the correspondence between the first letter group and the initial consonant key value group and the key defined in the English alphabet set" are as follows: 1. Maintain the consistency of operation logic and reduce learning costs Reusing the mapping of the first button and the key value means that the key correspondence setting of the initial consonant module continues the previously established overall keyboard layout and mapping logic. After the user is familiar with the distribution of the English letter set determined by the first button and the key value mapping on the keyboard, there is no need to spend extra energy to understand and memorize a new set of initial consonant key correspondence rules. For example, if you already know that the letters on the keyboard are laid out in a specific grouping, order, and shared keys, then you can quickly get started with the relationship between the initial consonants and the corresponding ones, because they follow the same layout framework, which greatly reduces the difficulty of learning and mastering the initial consonant input method, making the operating logic of the entire pinyin input device more coherent and unified, so that users can adapt faster and skillfully use the input device for pinyin input.

[0039] 2. Simplify the mapping rule system and improve memory efficiency Since there is no need to construct complex and independent initial consonant key mapping rules separately, the entire mapping rule system has been simplified. The mapping of initial consonants is generated based on the existing first key and key value mapping, which reduces the number of different rules that need to be remembered and avoids the memory burden on users due to too many and too complicated mapping rules. Users only need to remember a relatively core set of basic correspondences between keyboard letters and keys to deduce the keys corresponding to the initial consonants, which significantly improves memory efficiency. For example, when you see the position of the letter corresponding to a certain initial consonant in the first letter group and its sharing relationship with other letters, you can immediately know the key to operate, which improves the reaction speed to the initial consonant input operation during the input process, thereby improving the overall input efficiency.

[0040] 3. It is conducive to integrating resources and improving the utilization of keyboard space By reusing the existing mapping, the key resources on the keyboard can be more effectively integrated to achieve a reasonable distribution of initial consonants. Based on the letter layout determined by the first key and key value mapping, combined with factors such as the frequency of use of initial consonants and input relevance, the initial consonants can be flexibly arranged on appropriate keys, avoiding repeated planning of keyboard space or waste of key resources. For example, those initial consonants with higher frequency of use can correspond to key positions that are more convenient to operate (based on the comfortable operating area under the first key and key value mapping), giving full play to the role of each keyboard key in initial consonant input, achieving optimal allocation of resources, and also making the distribution of initial consonants on the keyboard more in line with the actual needs of input operations, which helps to improve the fluency and speed of input.

[0041] 4. Facilitate unified management and adjustment, and enhance system adaptability If the key mapping of the entire pinyin input device needs to be adjusted and optimized later, such as changing the correspondence between the English letter set and the key according to user feedback or new input requirements, it is only necessary to make a unified modification at the source of the first key and key value mapping. Because the initial consonant module reuses this mapping, the key correspondence of the initial consonant can also be automatically updated, without the need to adjust the mapping rules of the initial consonant one by one, which greatly improves the convenience of system management and maintenance, and enhances the adaptability of the entire input device to different application scenarios and changes in different user needs, ensuring that it can continue to maintain good input performance and user experience.

[0042] Optionally, the single vowels include a, o, e, i, u, ü, er; The mapping between the third button and the key value generates the configuration of the second letter group and the single vowel key value group and the button defined in the English alphabet set according to the following matching definition model: The single vowels a, o, e, i, u and their single vowel key values ​​are mapped to the A letter key, O letter key, E letter key, I letter key and U letter key of the keyboard respectively, the single vowel ü and its single vowel key value are mapped to the B letter key, and the single vowel er arrangement and its single vowel key value are mapped to the R letter key.

[0043] To this end, the technical benefits brought by the above-mentioned single vowel key and key value mapping configuration method are as follows: 1. Use existing keyboard knowledge to get started quickly For the single vowels a, o, e, i, and u, they are mapped to the corresponding A, O, E, I, and U letter keys on the keyboard, respectively, making full use of the user's familiarity with the positions of these letters in the conventional keyboard layout. When using the computer keyboard for daily text input, operations, and other activities, users have long formed muscle memory and visual cognition habits for the positions of these letters. When using the pinyin input device to input single vowels, this habit can quickly locate the corresponding key without spending extra time to memorize the new position, greatly reducing the learning cost, allowing users to quickly get started with pinyin input operations, and improving the convenience and ease of use of the input method for the first time.

[0044] 2. Reasonable layout based on usage characteristics to improve input efficiency The frequency of use of the single vowel ü is relatively low, and its single vowel key value is mapped to the B letter key, taking into account its particularity in the input process. The position of the B key on the keyboard ensures that even if it needs to be operated separately to input "ü", it will not cause significant interference to the overall input fluency. Moreover, due to its low frequency of use, such a layout arrangement makes reasonable use of relatively less commonly used key resources without affecting input efficiency. As for the single vowel er, it is arranged on the R letter key. This setting is easy to remember. At the same time, when inputting pinyin containing the "er" syllable, the user can find the corresponding key to operate more naturally and quickly, which optimizes the convenience of single vowel input as a whole, thereby improving the efficiency of pinyin input and reducing the time spent on finding keys.

[0045] 3. Regular mapping facilitates memory and enhances input accuracy Overall, this mapping configuration of single vowels presents a regular and easy-to-understand state. Most commonly used single vowels correspond to keyboard keys with the same letters, and special single vowels (such as ü, er) are reasonably arranged according to their own characteristics, forming a set of clear and definite mapping rules. In the process of memorization, users can easily grasp the key positions corresponding to each single vowel according to such rules, and are not prone to confusion or misremembering. In actual input, accurately pressing the corresponding keys helps to improve the accuracy of input, reduce the problem of the entire pinyin spelling errors caused by single vowel input errors, and improve the overall input quality and effect.

[0046] 4. Comply with operating habits and ergonomics to reduce hand burden From the perspective of operating habits and ergonomics, the keys mapped to single vowels are distributed relatively reasonably on the keyboard, in line with the natural operating range and movement habits of fingers. For example, the key positions corresponding to commonly used single vowels are usually in areas that are easy for fingers to reach and comfortable to operate. When continuously inputting pinyin, fingers do not need to perform unnatural movements such as overstretching and twisting to find the corresponding keys, which reduces the generation of hand fatigue, allowing users to maintain a good operating state during long-term pinyin input, further ensuring the smoothness and comfort of input, and improving the user experience.

[0047] Optionally, the basic complex vowels include ou, ei, en, eng, ang, an, ai, ao; The mapping of the fourth button and the key value generates the configuration of the fourth letter group and the basic vowel key value group and the button defined in the English letter set according to the following matching definition model; The basic complex vowels ou, ei, en, eng, ang, an, ai, ao and their basic vowel key values ​​are mapped to the S letter key, D letter key, F letter key, G letter key, H letter key, J letter key, K letter key and L letter key in sequence.

[0048] Therefore, the technical benefits of the above-mentioned basic complex vowels and key-value mapping configuration method are as follows: 1. Regular layout facilitates memory and reduces learning costs The basic complex vowels are mapped to the letter keys S, D, F, G, H, J, K, and L in the middle row of the keyboard in a specific order, presenting a very regular and orderly layout feature. When learning and memorizing, users can easily remember the keys corresponding to each basic complex vowel based on this clear corresponding order, without having to spend a lot of energy to memorize complex and irregular mapping combinations. For example, as long as you remember the corresponding relationship of "ou corresponds to the S key, ei corresponds to the D key" arranged in sequence, you can quickly master the key mapping of the basic complex vowels, which greatly reduces the memory burden of the basic complex vowel input part when learning to use the pinyin input device, making it easier for users to get started and use it proficiently.

[0049] 2. Centralized layout facilitates operation and improves input efficiency The basic complex vowels are mapped to the letter keys in the middle row of the keyboard, so that the fingers have a relatively concentrated range of movement when operating these keys to input basic complex vowels, making the operation more convenient. In the actual input process, the fingers do not need to move across areas on the keyboard significantly, reducing the operation time and the complexity of hand movements. For example, when continuously inputting pinyin containing multiple basic complex vowels, the fingers can switch operations more smoothly between the keys in this row. Compared with the layout of keys scattered in different areas, it can significantly increase the input speed, make the entire pinyin input process more efficient, and improve the overall efficiency of text input.

[0050] 3. Symmetrical distribution conforms to visual and operating habits and enhances input accuracy These basic complex vowels are arranged symmetrically on the S, D, F, G, H, J, K, and L keys. This symmetrical distribution conforms to people's visual cognitive habits for neat and regular layouts, making it easier for users to find and confirm keys more quickly and accurately. At the same time, from an operational perspective, the symmetrical layout makes finger operations more coordinated. For example, the fingers of both hands can more naturally operate the corresponding keys according to the symmetrical rules, reducing input errors caused by uncoordinated operations or accidental touches of other keys, helping to improve input accuracy, ensure that the input pinyin is accurate, and thus improve the quality of text output.

[0051] 4. Integrate keyboard resources and optimize space utilization By systematically mapping basic complex vowels to a specific set of keyboard keys, effective integration and rational use of keyboard space is achieved. This not only avoids the waste of key resources due to the excessive dispersion of the mapping of basic complex vowels, but also ensures that they have relatively independent and easy-to-operate exclusive key areas. In this way, in the key mapping planning of the entire pinyin input device, the relationship between basic complex vowels and other initials, single vowels, and derived vowels can be better coordinated, making the function allocation of each key on the keyboard more scientific and reasonable, giving full play to the potential of the keyboard in pinyin input, and laying a good foundation for achieving efficient and accurate pinyin input.

[0052] 5. It helps to form muscle memory and improve input fluency Since the layout of the keys for the basic complex vowels is regular and concentrated, after a certain period of practice, the user's fingers can easily form specific muscle memory for this group of keys. When inputting pinyin, the fingers will naturally press the corresponding keys accurately according to muscle memory to input the basic complex vowels, without the need for excessive brain thinking and repeated visual confirmation, which further improves the fluency of input, allowing users to be more comfortable when using the pinyin input device and get a better input experience.

[0053] Optionally, the derived complex vowels include ie, üe, ing, ong and iong, uang and iang, uo, iao, ua and ia, iu, ui and in, un and ün, uan ​​and üan, uai and ian; The mapping of the fifth key and key value is used to generate the configuration of the fifth letter combination and the derived final key value and key defined in the English letter set according to the following matching definition model: Based on the combination relationship between the simple vowels and basic complex vowels in the derived complex vowels and i, u, ü, the derived complex vowels and their derived final key values ​​are mapped to their upper and lower adjacent letter keys according to a set rule.

[0054] To this end, the technical benefits brought by the above-mentioned derived complex vowel key and key value mapping configuration method are as follows: 1. Use association to facilitate memory and reduce learning costs The key mapping is performed based on the combination relationship between the single vowels and basic complex vowels in the derived complex vowels and i, u, ü, so that the mapping rules establish a close logical association with these basic elements. When memorizing the keys corresponding to the derived complex vowels, the user can use the familiarity with the single vowels, basic complex vowels and their combination rules with specific vowels to remember the key positions of the derived complex vowels. For example, knowing the key position corresponding to "e" and the mapping rules after it is combined with "i", "u" and "ü" to form derived complex vowels, you can easily remember the corresponding keys of "ie", "üe", etc. This memory method based on the association of existing knowledge conforms to people's cognitive laws. Compared with the isolated memory of the key mapping of each derived complex vowel, it can greatly reduce the learning cost, facilitate users to master the input rules more quickly, and quickly get started with the pinyin input device.

[0055] 2. Follow finger operation habits to improve input efficiency The derived complex vowels are mapped to their respective upper and lower adjacent letter keys according to the set rules, which fully considers the convenience and consistency of finger operation. In the actual input process, adjacent fingers are usually responsible for adjacent key operations. When inputting pinyin containing derived complex vowels, the fingers can switch between adjacent keys in a natural and smooth movement without large leaps or awkward stretching movements. For example, some derived complex vowel combinations corresponding to adjacent keys operated by the same finger or adjacent fingers make finger operation more convenient and reduce operation time, thereby effectively improving the input rhythm and overall efficiency, making pinyin input faster.

[0056] 3. Clear rules enhance accuracy and reduce input errors This mapping configuration method based on specific combination relationships and adjacent key positions makes the key mapping rules for derived complex vowels clear and well-organized. When inputting, as long as the user is familiar with the corresponding rules, he can accurately press the corresponding keys to input derived complex vowels, and it is not easy to make key misoperations due to vague memory or confusion of rules. Clear rules reduce the probability of the entire pinyin spelling error caused by incorrect input of derived complex vowels during the input process, which helps to improve the accuracy of input, ensure that the pinyin entered each time is correct, and thus improve the quality of text input.

[0057] 4. Strengthen the overall layout logic to facilitate understanding and mastery The mapping configuration of the entire derived complex vowels is integrated into a logical framework based on single vowels and basic complex vowels, combined with the combination of i, u, ü and the relationship between adjacent key positions, which strengthens the logic and systematicness of the entire pinyin input device in the mapping of vowels. During the learning and use process, users can understand the relationship between different types of vowels (single vowels, basic complex vowels, derived complex vowels) and the rationality of their layout on the keyboard keys as a whole, and master the operation mode of the input device more comprehensively and deeply, rather than memorizing the mapping of each element in isolation. This helps users better control the input device and improve the proficiency and stability of use.

[0058] 5. Adapt to diverse input scenarios and improve versatility Through this mapping method of derived complex vowels based on combination relationships and adjacent key positions, it is possible to flexibly adapt to various different pinyin input scenarios and diverse vocabulary spelling requirements. Whether it is daily text communication, document editing, or text creation in professional fields, the derived complex vowels in different pinyin combinations can be input conveniently and quickly according to established rules, so that the pinyin input device can show good input performance in a variety of application scenarios, enhance its versatility and applicability, meet the pinyin input requirements of different users in different usage scenarios, and improve the overall user experience.

[0059] Optionally, based on the combination relationship between the single vowels and basic complex vowels in the derived complex vowels and i, u, ü, the derived complex vowels and their derived final key values ​​are mapped to their respective upper and lower adjacent letter keys according to at least any one rule item defined by the rule model set as follows: Based on the e corresponding to the E letter key, the üe and its derived finals key values ​​have a mapping relationship with the W letter key, and the ie and its derived finals key values ​​have a mapping relationship with the Q letter key, so that the E letter key, the W letter key, and the Q letter key receive trigger operations of three adjacent fingers; Based on the ou corresponding to the S key, the iu and its derived vowel key values ​​have a mapping relationship with the X key, so that the S key and the X key receive a trigger operation of the same finger; Based on the corresponding ei on the D letter key, the ui and its derived vowel key values ​​have a mapping relationship with the C letter key, so that the D letter key and the C letter key receive the trigger operation of the same finger; Based on the en corresponding to the F letter key, the un and its derived finals key values ​​have a mapping relationship with the V letter key, the ün and its derived finals key values ​​have a mapping relationship with the V letter key, and the in and its derived finals key values ​​have a mapping relationship with the C letter key, so that the F letter key and the V letter key receive the trigger operation of the same finger, and the C letter key receives the trigger operation of the adjacent finger; Based on eng corresponding to the G letter key, the ong and its derived finals key values ​​have a mapping relationship with the T letter key, the iong and its derived finals key values ​​have a mapping relationship with the T letter key, and the ing and its derived finals key values ​​have a mapping relationship with the R letter key, so that the G letter key, the T letter key, and the R letter key receive the trigger operation of the same finger; Based on ang corresponding to the H letter key, the uang and its derived finals key values ​​have a mapping relationship with the Y letter key, and the iang and its derived finals key values ​​have a mapping relationship with the Y letter key, so that the H letter key and the Y letter key receive the trigger operation of the same finger; Based on the a corresponding to the A letter key, the ia and its derived finals key values ​​have a mapping relationship with the Z letter key, and the ua and its derived finals key values ​​have a mapping relationship with the Z letter key, so that the A letter key and the Z letter key receive the trigger operation of the same finger; Based on an corresponding to the J letter key, the uan and its derived finals key values ​​have a mapping relationship with the N letter key, the üan and its derived finals key values ​​have a mapping relationship with the N letter key, and the ian and its derived finals key values ​​have a mapping relationship with the M letter key, so that the J letter key, the N letter key, and the M letter key all receive the trigger operation of the same finger; Based on the ai corresponding to the K letter key, the uai and its derived vowel key values ​​have a mapping relationship with the M letter key, and the ai and uai are adjacent to each other at the lower left side of the stroke, so that the K letter key and the M letter key receive the triggering operation of the adjacent fingers; Based on ao corresponding to the L letter key, the iao and its derived vowel key values ​​have a mapping relationship with the P letter key, and the ao and the iao form an upper right adjacent position, so that the L letter key and the P letter key receive the triggering operation of the adjacent fingers; Based on the similarity of pronunciation, the uo and its derived final key values ​​are mapped to the O letter key.

[0060] To this end, the technical benefits brought by the above-mentioned derived complex vowels and key mapping rule entries are as follows: 1. Adapt to finger operation habits and improve input efficiency 1. Collaborative operation of adjacent fingers is more convenient Settings like "E key, W key, Q key receive triggering operations from three adjacent fingers" allow adjacent fingers to perform key operations naturally and coherently when inputting pinyin containing derived complex vowels such as "ie" and "üe". Fingers do not need to make large leaps or adjustments, and the operation is smoother. It can effectively reduce the time cost of finger movement when inputting a single pinyin and speed up the input rhythm. This advantage is especially obvious when inputting multiple pinyins containing such derived complex vowels in succession, which can significantly improve the overall pinyin input efficiency.

[0061] 2. Use the same finger to reduce hand movement switching For situations such as "the S key and the X key receiving trigger operations from the same finger" (corresponding to derived complex vowels such as "iu") and other similar situations where the same finger operates adjacent keys, users can input related derived complex vowels with a simple flexion and extension of one finger, avoiding the complex operation of frequently switching fingers back and forth between areas responsible for different fingers, further simplifying the input action, making the input process easier and more efficient, and helping to improve the speed of text input.

[0062] 2. Use pronunciation association to assist memory and reduce learning costs 1. Based on the association memory of single vowels and basic complex vowels These rule entries are mapped based on the combination relationship between the single vowels and basic complex vowels in the derived complex vowels and "i", "u" and "ü". For example, the key mapping of "ie" and "üe" is determined based on the "e corresponding to the E letter key", which makes use of the user's existing cognition and memory of single vowels and basic complex vowels. Users can remember the key positions corresponding to derived complex vowels by associating single vowels, basic complex vowels and their combination rules, making the memory process more logical and relevant, and reducing the difficulty of memorizing the key mapping of derived complex vowels alone.

[0063] 2. Similar pronunciations aid memory For example, "based on the similarity of pronunciation, the key values ​​of 'uo' and its derived finals are mapped to the letter key of 'O'". With the help of the similarity of pronunciation, users can easily remember the key corresponding to "uo" through the connection of pronunciation when memorizing, which enhances the relevance and fun of memory. Overall, these mapping rules established based on pronunciation association help users to grasp the key mapping of derived complex finals more quickly and firmly, making it easier for users to quickly get started using the pinyin input device.

[0064] 3. Enhance the logic of button layout to facilitate overall control 1. Rules clearly present logical relationships Each mapping rule clearly shows the logical connection between derived complex vowels and corresponding keys based on specific phonetic combinations, pronunciation similarity and other factors, making the mapping layout of the entire derived complex vowels on the keyboard clear and logical. In the process of learning and using, users can understand from these rules how different derived complex vowels are mapped to corresponding keys based on their own characteristics, rather than facing a bunch of random mappings without any clue, which makes it easier to grasp the operating logic of this part of the pinyin input device as a whole.

[0065] 2. Systematic connections help you understand the whole picture Through the coordination of various rule entries, a systematic association framework is formed around derived complex vowels, simple vowels, basic complex vowels and keyboard key layout. Users can understand the mapping of the vowel part in the entire pinyin input device from the perspective of the system, better integrate the input of derived complex vowels with the input of other types of vowels, comprehensively and deeply master the entire pinyin input operation, and improve the ability to control the input device.

[0066] 4. Reduce input errors and improve input accuracy 1. Clarify the rules to avoid misoperation Since each rule clearly defines the derived complex vowels and their corresponding specific keys, and combines reasonable factors such as finger operation habits, users can accurately press the corresponding keys to enter the derived complex vowels as long as they follow the established rules. This clear and unambiguous rule greatly reduces the possibility of accidentally pressing other keys due to vague memory and confusion of rules, and reduces the probability of errors when entering derived complex vowels, thereby ensuring the accuracy of pinyin input.

[0067] 2. Adjacent relationship assisted precise input For example, the adjacent relationship setting of "'ai' and 'uai' corresponding to the K key are adjacent to it on the lower left side, so that the 'K' key and the 'M' key receive the operation of adjacent fingers" allows users to rely on the natural touch and operation habits of their fingers on adjacent keys during the input process to more accurately locate and operate the corresponding keys, further improve the accuracy of input, ensure that the pinyin entered each time is correct, and thus improve the quality of text input.

[0068] 5. Improve user experience and increase input comfort 1. Ergonomic operating experience These mapping rules based on finger operation habits fully consider the principles of ergonomics, making the fingers move more naturally and comfortably when operating the keyboard to input derivative compound vowels, reducing the hand fatigue caused by uncomfortable or awkward key operations. Whether it is the operation of the same finger or the coordinated operation of adjacent fingers, it conforms to the natural movement range and force application method of the hand, enabling users to maintain a good operation state even when using the pinyin input device for a long time, and enhancing the comfort during use.

[0069] 2. Smooth input brings a good experience With the convenience, accuracy, and comfort brought by the rules, users can complete pinyin input more smoothly during the input process, reducing the irritability caused by various problems (such as difficult operations, frequent errors, etc.), enhancing the overall satisfaction of users with the pinyin input device, bringing a good input experience to users, and helping to improve the acceptance and competitiveness of the input device in the market.

[0070] The schematic diagrams when applying the solutions of the embodiments of the present application to a 26-key keyboard and a 17-key keyboard are respectively as Figure 1B 、 Figure 1C 、 Figure 1D shown. Among them, Figure 1C in, it is a color 26-key keyboard, and the marked colors are used for the same-color distinction related to adjacent compound vowels.

[0071] Refer to the above Figure 1B and Figure 1C and Figure 1D It can be seen that the arrangement of keys, initials, and compound vowels on the keyboard is as follows in detail: (1) The arrangement of initials including zero initials (Capital letters represent the names of English letter keys, and lowercase letters represent Chinese pinyin, the same throughout the text) Q, W, R, T, Y, U, I, P correspond to q, w, r, t, y, sh, ch, p in sequence; S, D, F, G, H, J, K, L correspond to s, d, f, g, h, j, k, 1 in sequence; Z, X, C, V, B, N, M correspond to z, x, c, zh, b, n, m in sequence; V, I, U correspond to zh, ch, sh respectively; Zero initial scheme: It refers to the processing scheme of the compound vowel syllables without initials in the full pinyin in the double pinyin. In this scheme, the first letter of the compound vowel is used as the zero initial, that is, the first letter of the compound vowel is regarded as the initial, and the zero initial double pinyin combination is "zero initial + the key where the compound vowel is located", for example: a = aa, o = oo, e = ee, ai = ak, en = ef, ou = os, ang = ah; (2) The arrangement of compound vowels: Q, W, E, R, T correspond to ie, üe, e, er and ing, ong and iong respectively; Y, U, I, O, P correspond to uang and iang, u, i, o and uo, iao respectively; A, S, D, F, G, H, J, K, L correspond to a, ou, ei, en, eng, ang, an, ai, ao respectively; Z, X, C, V, B correspond to ua and ia, iu, ui and in, un and ün, ü respectively; N and M correspond to üan and uan, ian and uai respectively; (3) Principles of Arrangement of Initials and Finals The arrangement of finals of the present invention is based on phonetic notation and divides finals into three categories: single finals, basic complex finals and derived complex finals. The single finals include a, o, e, i, u, ü and er; the basic complex finals include ou, ei, en, eng, ang, an, ai and ao; other finals formed by combining single finals and basic complex finals with i, u and ü are called derived complex finals. The derived complex finals include ie, üe, ing, ong and iong, uang and iang, uo, iao, ua and ia, iu, ui and in, un and ün, üan and uan, ian and uai.

[0072] The positions of the single vowels a, o, e, i, and u on the original English keyboard remain unchanged; the single vowel ü is arranged on the B key, because pressing the B key requires a large movement of the left hand, which is not very convenient, so the single vowel ü, which is used least frequently, is arranged on the B key; the single vowel er is arranged on the R key of the ER key for easy memorization; The basic complex vowels ou, ei, en, eng, ang, an, ai, ao are arranged symmetrically on the S, D, F, G, H, J, K, L keys in the middle row of letter keys; the derived complex vowels composed of the simple vowels and the basic complex vowels and i, u, ü are arranged in a relatively regular manner on their respective upper and lower adjacent key positions for easy memorization; E, W, Q keys: Because the E key corresponds to e, the W key corresponds to üe, and the Q key corresponds to ie. The three keys are operated by three adjacent fingers; S, X keys: Because the S key has ou, the X key has iu, and the two keys are operated by the same finger; D and C keys: Because ei is set on the D key, ui is set on the C key, and the two keys are operated by the same finger; F, V, C keys: Because the F key has en, the V key has un and ün, and the C key has in. The F and V keys are operated by the same finger, and the C key is operated by adjacent fingers. G, T, R keys: Because the G key corresponds to eng, the T key corresponds to ong and iong, and the R key corresponds to ing. The three keys are operated by the same finger; H and Y keys: Because ang is set on the H key, uang and iang are set on the Y key, and the two keys are operated by the same finger; A and Z keys: Because the A key has a, the Z key has ia and ua, and the two keys are operated by the same finger. J, N, M keys: Because the J key corresponds to an, the N key corresponds to uan and üan, and the M key corresponds to ian. The three keys are operated by the same finger; K, M keys: Because the K key corresponds to ai, the M key corresponds to uai, located at the lower left side of ai, and the two keys are operated by adjacent fingers; L and P keys: Because the L key has ao, the P key has iao, which is located on the upper right side of ao. The two keys are operated by adjacent fingers. Set uo to the letter O key, because o and uo have similar pronunciations; er arranges the ER key on the R key for easy memorization; ü, the least frequently used single vowel, is placed on the B key.

[0073] In addition, when used specifically, when the double spelling input method of the present invention is applied, as long as the double spelling scheme file of the conventional pinyin input method is modified according to the setting scheme of the present invention, the double spelling key position therein can be realized, and Chinese input can be realized. For example, the Baidu Pinyin input method modifies the double spelling key position according to the double spelling input scheme of the present invention, and Chinese character input can be realized. Some Pinyin input method programs allow users to customize the double spelling key position, as long as the user customizes the double spelling key position therein according to the present invention, it can be actually applied. For example, using the double spelling function of the Baidu Pinyin input method and the Microsoft Pinyin input method, the user sets the double spelling key position therein according to the present invention, and Chinese input can be realized.

[0074] Furthermore, in the above configuration, as long as the positions of the single vowels a, o, e, i, and u on the original English alphabet keyboard remain unchanged, the single vowel ü with a lower frequency of use is arranged on the B key; the single vowel er is arranged on the R key of the ER key; the middle row of the letter keys maps the eight basic complex vowels ou, ei, en, eng, ang, an, ai, and ao to the S, D, F, G, H, J, K, and L keys in sequence, with a left-right symmetrical layout; the derived complex vowels composed of the single vowels, the basic complex vowels, and i, u, and ü are all arranged relatively regularly on their respective upper and lower adjacent key positions.

[0075] Moreover, the basic complex vowels of the input scheme of the present invention are arranged symmetrically on the left and right, the derived complex vowels are closely related to the basic complex vowels and the single vowels, and the seventeen-key key map is specially designed for the mobile phone screen, which reduces the number of erroneous key presses in mobile phone input, solves the pain point that the vowel mapping of other double-pinyin input schemes is difficult to remember, reduces the learning cost and the difficulty of getting started, and is more conducive to the popularization and application of double-pinyin input.

[0076] Figure 2 This is a flow chart of a pinyin input method according to an embodiment of the present application.

[0077] Optionally, the method includes: mapping the first key and the key value according to the following matching definition model to generate a configuration of a correspondence between an English letter set and the key: The English letter set includes a first letter group, a second letter group, and a third letter group. The first letter group includes letters: QWERTYUIOP, the second letter group includes letters: ASDFGHJKL, and the third letter group includes letters: ZXCVBNM; Arrange the letters included in the first letter group: QWERTYUIOP in sequence from left to right on the first row of the keyboard and assign a key to each letter in QWERTYUIOP; Arrange the letters included in the second letter group: ASDFGHJKL in sequence from left to right on the second row of the keyboard and assign a key to each letter in ASDFGHJKL; The letters included in the third letter group: ZXCVBNM, are arranged in sequence from left to right on the second row of the keyboard and a key is assigned to each letter in ZXCVBNM.
