Description

1. Technical Field

[0001] The present invention relates to the technical field of Chinese pinyin input for touch screen devices, especially for various touch screen devices such as mobile phones and tablets. In the international patent classification system, the present invention is classified into G06F3 / 0488 (touch screen interaction), G06F3 / 0323 (gesture control), and G06F 40 / 274 (optimization of pinyin input method). Specifically, the present invention provides a Chinese pinyin glide input system based on multi-directional glide gestures, aiming to significantly improve input efficiency and reduce the mis-touch rate. 2. Background Art

[0002] (1) Deficiencies of the Existing Technology

[0003] 1. Operational redundancy: When inputting compound vowels, such as "iong", existing touch screen pinyin input methods often require users to perform multiple glide operations or frequently switch keyboards, which greatly increases the input time and operational complexity.

[0004] 2. Single layout: The keyboard layout of existing input methods is relatively single, and does not fully consider the differences in different screen sizes, as well as the habits of users' single-handed or two-handed operations. This results in a poor input experience for users in different scenarios.

[0005] 3. Initial consonant and final conflict: When the initial consonants "j / q / x" are combined with the finals "o / ong", for example, "j+ong", existing input methods require users to perform manual switching and cannot achieve automatic matching, which brings inconvenience to users.

[0006] 4. When performing glide input, the glide path is long, the mis-touch rate is high, it is difficult to find the path, and memory glide input cannot be achieved.

[0007] (2) Solution Ideas of the Present Invention

[0008] The present invention aims to solve the above problems through four innovative matrix keyboard layouts and a unique dynamic initial consonant and final mapping algorithm, providing users with a more efficient and convenient pinyin input experience. 3. Summary of the Invention

[0009] (1) Core Innovation Points

[0010] 1. Matrix keyboard layout system: The present invention designs four different keyboard layouts, namely Layout A, Layout B, Layout C, and Layout D.

[0011] Layout A: Full keyboard layout, presented through the following 5-row and 10-column matrix, which is basically arranged according to the qwerty keyboard layout:

[0012] The first row: [empty][empty][empty][empty][empty][empty][empty][empty][empty][empty]

[0013] Second row: [blank] q w r t y zh ch sh [blank]

[0014] Third row: [blank] s d f g h j k l [blank]

[0015] Fourth row: [blank] z x c b n m p 0 / er [blank]

[0016] Fifth row: [blank] [blank] [blank] [blank] [blank] [blank] [blank] [blank] [blank] [blank]

[0017] This layout completely covers 23 initial consonants, including "zh / ch / sh", and supports the quick gliding input of high-frequency compound vowels.

[0018] Layout B: The initial consonants are grouped and arranged according to the place of articulation, and the core area uses a 5-row and 10-column matrix:

[0019] First row: [blank] [blank] [blank] [blank] [blank] [blank] [blank] [blank] [blank] [blank]

[0020] Second row: [blank] b p m f d t n l [blank]

[0021] Third row: g k h j q x y w [blank]

[0022] Fourth row: [blank] z c s zh ch sh r [0 / er] [blank]

[0023] Fifth row: [blank] [blank] [blank] [blank] [blank] [blank] [blank] [blank] [blank] [blank]

[0024] The initial consonants are grouped according to bilabial sounds "b / p / m / f", apical sounds "d / t / n / l", etc., basically in the order of the Chinese Pinyin alphabet, effectively reducing the user's memory cost.

[0025] Layout C: The compact layout uses a 6-row and 8-column matrix:

[0026] First row: [blank] [blank] [blank] [blank] [blank] [blank] [blank] [blank]

[0027] Second row: [blank] b p m f r 0 / er [blank]

[0028] Third row: [blank] d t n l y w [blank]

[0029] Fourth row: [blank] g k h j q x [blank]

[0030] Fifth row: [blank] z x c zh ch sh [blank]

[0031] The sixth row: [Empty][Empty][Empty][Empty][Empty][Empty][Empty][Empty]

[0032] The empty key area of this layout can be customized with symbols or numbers by the user, and is especially suitable for devices with a small screen size.

[0033] Layout D: Nine-key core layout, fuzzy input matrix:

[0034] [Empty][Empty][Empty][Empty][Empty][Empty][Empty]

[0035] [Empty][Empty]bp mf dt[Empty][Empty]

[0036] [Empty][Empty]nl 0 / er gkh[Empty][Empty]

[0037] [Empty][Empty]jqx zcs zhchsh[Empty][Empty]

[0038] [Empty][Empty][Empty][Empty][Empty][Empty][Empty]

[0039] This layout uses a multi-letter key fuzzy input method. Short presses are the default initials, and long presses can switch the initials. Its dynamic expansion area supports user-defined functions, and the y / w keys can be derived by sliding through the 0 / er key (0 key ← = y, 0 key → = w). The number of [Empty] keys can be increased as needed.

[0040] In the above layout, [Empty] is the input guide area keyboard, and function keys, number keys, symbol keys, etc. can be customized according to needs.

[0041] 2. Dynamic initial-final binding rules

[0042] Automatic error correction: When j / q / x is intelligently combined with iang / iong, the user triggers the combination of the "j / q / x" key and "ang / ong" through a sliding operation, and the system will automatically convert it to "iang / iong". For example, when inputting "q+ang", the system will automatically output "qiang". When inputting "lue" and "nue", the system automatically outputs "lve" and "nve".

[0043] o / ong dynamic binding: The system will automatically perform dynamic binding of "o / ong" according to the legality of the initial. If the initials are d, t, n, l, g, h, k, j, q, x, z, c, s, r, zh, ch, sh, y, w, the combination with "o" is invalid, and the system will automatically bind it to "ong", such as "l+o / ong→long", "d+o / ong→dong"; if the initials are b, p, m, f, the combination with "o" is valid, such as "m+o / ong→mo".

[0044] 3. Multi - directional Gliding Input Logic

[0045] Starting from any initial consonant (including the zero initial consonant 0 / er key), gliding in different directions, each gliding of one key or continuous gliding maps different finals or final combinations, which can cover all pinyin combinations without duplicate paths. The mapping logic is as follows in the table:

[0046] Sliding direction Mapping finals Priority rule Swipe up↑ a Swipe down↓ n Swipe down↓ + Swipe down↓ (Alternative: Swipe down↓ + Swipe up↑) g (Generate ng) Continuous action trigger Swipe left← i Swipe right→ u Applicable to j / q / x / y Upper left↖ ing Shortcut path Upper right↗ e Lower right↘ v(ü) Lower left↙ o / ng Dynamically bind to "o” or "ong” 0 / er Lower right↘ er Dynamically bind to er (when v is not the initial consonant of "0”) When starting to slide from 0 / er For the "0” initial consonant key, directly generate the final IV. Description of the Drawings

[0047] 1. Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 Are respectively the key distribution diagrams of keyboard layouts A, B, C, and D.

[0048] The four keyboard layouts are arranged in a matrix and clearly shown in a vertical comparison manner. The [empty] key is represented by the "blank" key.

[0049] 2. Figure 5 : Diagram of the mapping relationship between the gliding direction and finals, with dynamic binding logic, visually presenting the finals corresponding to different gliding directions and the binding rules, forming a memory rule for finals. □ represents any key. Vertically, a, n, g; horizontally, i, u, and diagonally clockwise are ing, e, v(ü), o / ong in sequence; i is adjacent to ing, and u is adjacent to v(ü), and the memory rule reduces the learning cost. V. Specific Embodiment

[0050] (1) Example 1:

[0051] Taking keyboard layout A as an example

[0052] 1. Operation Steps

[0053] (1) Glide "zh↑" respectively to input "zha", glide "zh↑↓" to input "zhan", glide "zh↑↓↓" to input "zhang", glide "zh→↑↓" to input "zhuang", input "zhua", "zh→↑↓↓" to input "zhuang", and finally select the candidate character or word.

[0054] (2) Glide "j←↙" to generate "jiong" or "j↙", and the system will bind "o / ong" to "iong" according to the dynamic binding rule. Finally, output "jiong", and then select the candidate character or word.

[0055] 2. Technical Details

[0056] When the acceleration of the gliding trajectory is greater than 2 cm / s², the system will determine it as a continuous action.

[0057] (2) Embodiment 2:

[0058] Taking the keyboard layout D as an example

[0059] Input "long"

[0060] 1. Operation steps

[0061] When inputting in a fuzzy manner, according to the context, click on the multi-letter key "bp". If swiping to the right → it may be "bu" or "pu", and select according to the context. If performing a left-down swipe operation (↙), the system will bind "o / ong" as "o", and it may be "bo" or "po"

[0062] 2. Technical details

[0063] When the sliding length is greater than 1.5 cm, the system will determine it as a valid direction.

[0064] (3) Solutions for the sliding path exceeding the screen range (layouts B and C)

[0065] Through a comprehensive solution of trajectory prediction algorithm, hardware edge extension, and user behavior modeling, the problem of the sliding path exceeding the screen range can be effectively solved or the positions of individual keys can be changed.

[0066] (4) Implementing this Chinese sliding input technology algorithm requires combining technologies such as sliding trajectory recognition, pinyin coding mapping, dynamic layout optimization, and machine learning error correction.

[0067] VI. Technical effects

[0068] 1. Efficiency improvement: Through the input system of the present invention, the input steps of high-frequency compound vowels are reduced by 70%, greatly improving the input efficiency.

[0069] 2. False touch rate reduction: The false touch rate of layout D is lower than 5%, significantly better than traditional nine-key input methods.

[0070] 3. Wide coverage: The input system of the present invention supports 100% of the GB / T 18031-2020 standard pinyin, including rare syllables such as "nü".

[0071] 4. Low learning cost forms a memory-based sliding input.
