Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of human-computer interaction, and in particular to an information input device and a pinyin input method thereof. BACKGROUND

[0002] As a portable information input device, the game controller has significant advantages in game interaction and smart TV scenarios due to its characteristics of not needing to rely on a placement plane and supporting multi-pose operation. A traditional general game controller usually integrates physical control units such as direction keys, joysticks, trigger keys, and multifunction keys, and complex instruction input can be achieved through combined operation. However, the existing Chinese character input scheme of the game controller needs to rely on a full-screen virtual English keyboard interface when performing text input, and the user needs to select letters to form pinyin on the full-screen virtual English keyboard interface through a joystick or direction keys, and then convert the pinyin into Chinese characters. Such an input method often has certain defects:

[0003] 1. Long operation path: the virtual keyboard needs to display 26 letters globally, and the user must move the focus between densely arranged small-size keys through the joystick to select letters to input a single pinyin (such as "zh", which needs to first locate "z" and then move to "h"), and the joystick operation frequency is high and the operation path is redundant;

[0004] 2. Low-efficiency interface interaction: the full-English virtual keyboard usually occupies a large amount of screen space and is not suitable for use on a small screen, and the small letter spacing leads to a high rate of misselection, and the user needs to frequently switch attention to accurately position the cursor to the target letter during the input of letters, which is contrary to the logic of fast operation of the game controller.

[0005] The above defects make the text input efficiency of the game controller much lower than that of the keyboard, and seriously restrict the application of the game controller in text-intensive scenarios such as chatting and searching. Therefore, it is urgent to develop a technical scheme that meets the operation characteristics of the general game controller and can significantly improve the pinyin input efficiency. SUMMARY

[0006] In view of the deficiencies in the prior art, the present application provides an information input device and a pinyin input method thereof, aiming to solve the problems of redundant operation path and low input efficiency of the general game controller in the field of text input in the prior art.

[0007] According to an embodiment of the present application, an information input device realizes selection input of information through operation signals of physical keys, and the information input device comprises:

[0008] a initial letter input unit configured to switch an initial letter page in response to an operation signal of a first key, and determine an initial letter in the initial letter page in response to an operation signal of a first joystick;

[0009] a syllable input unit configured to switch a syllable page in response to an operation signal of the second key and determine a syllable in the syllable page in response to an operation signal of the second joystick;

[0010] a Chinese character input unit configured to generate a candidate Chinese character according to the determined initial and syllable in response to a pinyin confirmation signal of the third key and input a selected Chinese character according to operation signals of the cross key and the fourth key.

[0011] As a further solution, the initial page comprises a plurality of ring-shaped initial tables arranged in pages, and the initial input unit is specifically configured to switch the ring-shaped initial tables in a preset cyclic order in response to each pressing operation of the first key.

[0012] As a further solution, the initial input unit is further specifically configured to identify the moving direction of each moving operation in sequence in response to a plurality of continuous moving operations of the first joystick and determine the selection of the initial in the ring-shaped initial table corresponding to the moving direction.

[0013] As a further solution, the syllable page comprises a plurality of ring-shaped syllable tables arranged in pages, and the syllable input unit is specifically configured to switch the ring-shaped syllable tables in a preset cyclic order in response to each pressing operation of the second key.

[0014] As a further solution, the syllable input unit is further specifically configured to identify the moving direction of each moving operation in sequence in response to a plurality of continuous moving operations of the second joystick and determine the selection of the syllable in the ring-shaped syllable table corresponding to the moving direction.

[0015] As a further solution, a mode switching unit is further included and configured to switch between the symbol input mode and the pinyin input mode in response to a switching signal of the first main key.

[0016] As a further solution, in the symbol input mode, the initial page is switched to a common symbol page, and the syllable page is switched to an uncommon symbol page; wherein the common symbol page comprises a plurality of ring-shaped common symbol tables arranged in pages, and the uncommon symbol page comprises a plurality of ring-shaped uncommon symbol tables arranged in pages.

[0017] As a further solution, a deletion unit is further included and configured to delete the determined pinyin or the selected Chinese character in response to a deletion signal of the second main key.

[0018] As a further solution, the application further comprises a quit unit configured to execute mode quit in response to an operation signal of a third main key; wherein, in response to recognizing a short press operation of the third main key, the symbol input mode or the pinyin input mode is quit; and in response to recognizing a long press operation of the third main key, the text input mode is quit.

[0019] In a second aspect, the application further provides a pinyin input method based on an information input device, comprising:

[0020] Receiving an operation signal of a first key to switch a page of initial consonants, and receiving an operation signal of a first joystick to determine an initial consonant in the page of initial consonants;

[0021] Receiving an operation signal of a second key to switch a page of final consonants, and receiving an operation signal of a second joystick to determine a final consonant in the page of final consonants;

[0022] Receiving a pinyin confirmation signal of a third key, generating a candidate Chinese character according to the determined initial consonant and final consonant, and inputting a selected Chinese character according to operation signals of a cross key and a fourth key.

[0023] Compared with the prior art, the application has the following beneficial effects:

[0024] 1.

[0025] 2. The application further adopts a combined key function partition design, in which the left trigger controls the ring-shaped final consonant table or the ring-shaped commonly used symbol table to switch the pages, the right trigger controls the ring-shaped final consonant table or the ring-shaped uncommonly used symbol table to switch the pages, and the target character is selected by moving the left / right joystick, thereby avoiding the multi-function conflict of the traditional direction key, reducing the probability of misoperation, and making the operation more in line with the characteristics of the handle.

[0026] 3. The application solves the problem of long operation path and low interface interaction caused by the traditional handle relying on the English keyboard for letter-by-letter input by reconstructing the handle pinyin input logic. The operation steps are further simplified, the input efficiency is greatly improved, and the application is particularly suitable for the fast text input needs of handle users in game, mobile device and other scenarios, significantly reduces the misoperation cost, and optimizes the user experience.

DETAILED DESCRIPTION

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] To better understand the technical principles expressed in this application, we need to know some things about "sound-sound separation characteristics".

[0043] The Pinyin input scheme of this invention is based on the initial and final separation characteristics of Chinese Pinyin: the Pinyin alphabet is divided into three parts: initial consonant, final vowel, and whole-word recognition. The whole-word recognition part can also be broken down into a similar way of initial consonant + final vowel, such as zhi = zh + i, yuan = y + uan. Therefore, a Pinyin can be composed of two parts.

[0044] The first part is the initials.

[0048] The second part is the vowels.

[0053] like Figure 1 As shown, Figure 1 This diagram shows the button layout of a modern, universally used gamepad. Although the shapes of different gamepads vary, their core button functions are highly universal. The buttons typically include: [Left Trigger] 1, [Right Trigger] 2, [Left Shoulder Button] 3, [Right Shoulder Button] 4, [Left Joystick] 5, [Right Joystick] 6, D-pad area [Up] [Down] [Left] [Right], main button area [X] [Y] [A] [B], special function buttons [SELECT] 11 and [START], etc.

[0054] Please refer to Figure 2 , based on the problems mentioned in the background art, this embodiment provides an information input device. In the pinyin input mode, the selection input of information is realized through the operation signals of physical buttons. The information input device includes:

[0055] A initial consonant input unit, which is configured to switch the initial consonant page in response to the operation signal of the first button 1, and determine the initial consonants in the initial consonant page in response to the operation signal of the first rocker 5;

[0056] A final input unit, which is configured to switch the final page in response to the operation signal of the second button 2, and determine the finals in the final page in response to the operation signal of the second rocker 6;

[0057] A Chinese character input unit, which is configured to generate candidate Chinese characters according to the determined initial consonants and finals in response to the pinyin confirmation signal of the third button 3, and input the selected Chinese characters according to the operation signals of the cross key 7 and the fourth button 4.

[0058] In this embodiment, by reconstructing the handle pinyin input logic, the core defects of the traditional virtual keyboard input scheme are solved. Specifically, for the lengthy operation of "spelling pinyin letter by letter" in the traditional scheme (for example, inputting "zh" requires 2 positioning operations), this device adopts an integrated selection mechanism for initial consonants / finals: the initial consonant page directly integrates composite initial consonant options such as "zh, ch, sh", and inputting "zh" only requires 1 rocker selection operation, significantly reducing the positioning times compared with the traditional scheme; the final page lists combined finals such as "ang, eng" independently, avoiding the step-by-step selection of "a + n + g", and reducing the rocker operation frequency of single pinyin input. Taking the input of "张 (zhāng)" as an example, the traditional scheme needs to complete 5 positionings of "z → h → a → n → g" on the virtual keyboard, while this device only needs 4 operations of "switching the initial consonant page + selecting zh + switching the final page + selecting ang", and the movement path of each operation is shorter, significantly optimizing the interface interaction efficiency.

[0059] Regarding the problems of space occupation and misselection of the virtual keyboard, in this scheme, only the current operating initial consonant page or final page is displayed on the screen during the input process, reducing a large number of display elements compared with the 26 letters of the full English virtual keyboard, adapting to small-screen devices and having less visual interference; the paged display can also expand the touch area of a single option, and配合物理按键的页切换逻辑,误选率较传统方案大大降低;用户无需在密集字母间频繁切换焦点,仅需关注当前页内有限选项,操作节奏与手柄物理控制的快捷逻辑高度匹配。

[0060] It should be noted that there seems to be an incomplete sentence in the translation of item . Please check and correct it if necessary. The original text "配合物理按键的页切换逻辑,误选率较传统方案大大降低" seems to be a bit unclear in its context. It might be better to rephrase it for a more fluent translation. For example, "Combined with the page switching logic of the physical buttons, the misselection rate is greatly reduced compared with the traditional scheme."In summary, this device significantly improves the efficiency of Pinyin input on the controller by upgrading the Pinyin input method from "letter-level selection" to "initial and final block selection," effectively solving the problem of low text input efficiency and providing technical support for the in-depth application of the controller in scenarios such as chat and search.

[0061] As a further solution, the vowel page includes a circular vowel table with several paginated settings. The vowel input unit specifically responds to each press of the second button 2, and sequentially switches the circular vowel table according to a preset cycle order.

[0062] like Figure 3 As shown, Figure 3 This is a schematic diagram of the input interface in a specific implementation example of this application, which includes an initial consonant display area 110, a final vowel display area 210, a pinyin candidate area 310, a Chinese character candidate area 410, and a text input box 510.

[0063] According to an embodiment of the present invention, the initial consonant display area 110 is used to display an initial consonant page, the initial consonant page includes a circular initial consonant table with several pages, and the initial consonant input unit specifically responds to each press operation of the first button 1, and sequentially switches the circular initial consonant table according to a preset cycle order.

[0064] Please see Figure 4 In Pinyin input mode, when the user presses the first button 1 on the handle, a circular initial consonant table pops up in the initial consonant display area 110. The circular initial consonant table includes several initial consonant pages, each containing a preset arrangement of initial consonant combinations, which can be displayed in pages. Each page contains 8-10 initial consonants, for example: the first page is "b, p, m, f, d, t, n, l", and the second page is "g, k, h, j, q, x, w, y", etc.

[0065] According to the embodiments provided by the present invention, the initial consonant input unit also specifically responds to a series of consecutive movement operations of the first rocker 5, sequentially identifies the movement direction of each movement operation, and determines the selection of the initial consonant in the circular initial consonant table corresponding to the movement direction.

[0066] Please see Figure 5 The user moves the first joystick 5, and selects a target initial consonant from the current circular initial consonant table according to the direction of the movement of the first joystick 5 (e.g., moving left selects the previous initial consonant, moving right selects the next initial consonant). When the joystick is stationary, the corresponding initial consonant is highlighted, and the pinyin candidate area displays the initial consonant (e.g., if "k" is selected, "k" is displayed in the candidate area). If the joystick returns to the center (is released), the currently selected initial consonant is canceled.

[0067] According to another embodiment of the present invention, the vowel page includes a circular vowel table with several pages, and the vowel input unit specifically responds to each press operation of the second button 2, and sequentially switches the circular vowel table according to a preset cycle order.

[0068] Please see Figure 6 In Pinyin input mode, when the user presses the second button 2 on the handle, a circular final table pops up in the final display area 210. The circular final table includes multiple final pages, each containing a preset arrangement of final combinations, which can be displayed in pages. For example, each page contains 10-12 finals, such as the first page containing "a, o, e, ai, ei, ao, eng / ueng", etc., and the second page containing "i, ia, ie, iao, iou / iu", etc.

[0069] According to another embodiment of the present invention, the vowel input unit also specifically responds to a series of consecutive movement operations of the second rocker 6, sequentially identifies the movement direction of each movement operation, and determines the selection of vowels in the circular vowel table corresponding to the movement direction.

[0070] Please see Figure 7 The user moves the second joystick 6 and selects the target vowel in the current circular vowel table according to the direction of the movement of the second joystick 6 (the operation logic is the same as the initial consonant). After selection, the vowel is displayed in the pinyin candidate area (e.g., if "uai" is selected, "uai" is displayed in the candidate area). If the joystick returns to the center, the currently selected vowel is canceled.

[0071] It should be noted that when an initial consonant and / or a final vowel are selected, the Chinese character input unit concatenates the selected initial consonant and final vowel in the pinyin candidate area to form a complete pinyin, and generates a candidate Chinese character table based on the pinyin matching algorithm, which is then displayed in the Chinese character candidate area. The pinyin in the candidate area includes one of the following: a single initial consonant, a single final vowel, or a combination of initial consonant and final vowel. In pinyin input mode, users can choose to select the final vowel directly without selecting the initial consonant, or they can select the final vowel first and then the initial consonant; that is, the selection of initial consonant and final vowel is independent. If the initial consonant is selected first and then the final vowel, the pinyin candidate area is concatenated in the order of "initial consonant + final vowel" (e.g., "k + uai" generates "kuai"); if the final vowel is selected first and then the initial consonant, it is concatenated in the order of "final vowel + initial consonant" (e.g., "ai + l" generates "ail"). If an invalid pinyin is selected, preventing the generation of candidate Chinese characters, the user must delete it manually.

[0072] like Figure 8 As shown, Figure 8This is a schematic diagram of the Chinese character candidate area in a specific embodiment of the present application. The initials and finals selected by the initial input unit and the final input unit are automatically concatenated into a complete pinyin, and a candidate Chinese character list is generated based on the pinyin matching algorithm and output and displayed in the Chinese character candidate area. Specifically, a candidate Chinese character list (such as "kuai" corresponding to "块, 快, 蒯, 筷", etc.) is generated based on the built-in pinyin-Chinese character matching algorithm (such as Trie tree retrieval) and displayed in the Chinese character candidate area. If the pinyin needs to be modified subsequently, the first button 1 / the second button 2 can be pressed, or the first / second right joystick can be directly moved, and new pinyin selection can be performed in the pinyin candidate area. The newly selected pinyin will be directly concatenated after the existing pinyin in the pinyin candidate area, and the candidate Chinese character list in the Chinese character candidate area will also change accordingly with the addition of the pinyin.

[0073] In another embodiment of the present invention, the information input device further includes a mode switching unit, which is configured to switch between a symbol input mode and a pinyin input mode in response to a switching signal of the first main button 8.

[0074] Specifically, in the pinyin input mode, by pressing the first main button 8, mutual switching between the symbol input mode and the pinyin input mode is performed. For example, in the pinyin input mode, when the first main button 8 is pressed, the pinyin candidate area is immediately cleared (such as clearing the original display of "kuai"), but the content of the Chinese character candidate area is retained (such as the already generated "块, 快, 蒯", etc.); if in the symbol input mode, when the first main button 8 is pressed, the pinyin candidate area is immediately cleared (such as clearing the original display of ","), but the content of the Chinese character candidate area is retained. Among them, the first main button 8 corresponds to the upper [Y] key of the handle.

[0075] As Figure 9 shown, Figure 9 This is a schematic diagram of the circular common symbols in a specific embodiment of the present application. In the symbol input mode, the initials page is switched to the common symbol page, and the finals page is switched to the uncommon symbol page; among them, the common symbol page includes several circular common symbol tables set by pages, and the uncommon symbol page includes several circular uncommon symbol tables set by pages. Specifically, in the symbol input mode: in response to the pressing operation of the first button 1, the initials display area 110 is switched from the circular initials table to the circular common symbol table, and in response to the pressing operation of the user on the second button 2 of the handle, the finals display area 210 is switched from the circular finals table to the circular uncommon symbol table. The symbol selection method is the same as the initials / finals selection method: in the symbol input mode, in response to the moving operation of the first joystick 5 of the handle, the target common symbol is selected from the current circular common symbol table according to the moving track direction and displayed in the pinyin candidate area; among them, only a single symbol is displayed in the pinyin candidate area, and the newly selected symbol covers the original symbol.

[0076] In another embodiment of the present invention, the information input device further includes a deletion unit configured to delete the determined pinyin or the selected Chinese characters in response to a deletion signal of the second main button 10.

[0077] It should be noted that when there are no candidate Chinese characters in the Chinese character candidate area, the function of the handle cross keys 7 is switched to control the cursor movement in the text input box 510. For example, when the user presses the left key of the cross keys 7, the cursor moves one character position to the left in the text input box 510 (when inputting "abc", the cursor moves from the end to the right of "b"); if the content in the text input box 510 exceeds one screen (such as a long text), pressing the up / down keys of the cross keys 7 can scroll the displayed content up / down, but the cursor position remains unchanged, and the cursor updates its position in real time when moving, facilitating the user to locate the editing point.

[0078] In a specific implementation process, in the pinyin input mode, in response to the pressing operation of the second main button 10 (the second main button 10 corresponds to the upper [X] key of the handle), the deletion strategy is executed; the deletion strategy is executed in the following manner: when there is content in the Chinese character candidate area, in response to the pressing signal of the second main button 10, the pinyin in the pinyin candidate area is deleted in sequence from right to left; when there is no content in the Chinese character candidate area, in response to the pressing signal of the second main button 10, the text or symbol to the left of the cursor in the text input box 510 is deleted according to the cursor position. When there is content in the Chinese character candidate area, for example, the selected pinyin (such as "kuai") is displayed in the pinyin candidate area, and at this time, candidate Chinese characters (such as "块, 快, 蒯") are displayed in the Chinese character candidate area. When the user presses the second main button 10, the characters in the pinyin candidate area can be deleted in sequence from right to left, and one character is deleted each time: initial pinyin "kuai" → press [X] once → "kua", and the candidate Chinese characters are updated to "夸, 垮, 挎"; press the second main button 10 again, updated to → "ku", and the candidate Chinese characters are updated to "哭, 苦, 库"; until the pinyin candidate area is cleared, and the Chinese character candidate area is cleared synchronously.

[0079] In another embodiment of the present invention, the information input device further includes an exit unit configured to execute mode exit in response to an operation signal of the third main button 9; wherein, in response to recognizing a short press operation of the third main button 9, the symbol input mode or the pinyin input mode is exited; in response to recognizing a long press operation of the third main button 9, the text input mode is exited.

[0080] In this embodiment, the third main button 9 corresponds to the [B] key on the handle. During the input process, the operation signal of the second button 2 is responded to at any time. When the third main button 9 is short pressed, the symbol input mode or the pinyin input mode is exited, or when the third main button 9 is long pressed, the text input mode is exited.

[0081] As Figure 10 shownFigure 10 The flowchart of the steps of a pinyin input method based on an information input device provided for a specific implementation of this application includes:

[0082] Receiving the operation signal of the first button 1 to switch the initial consonant page, and receiving the operation signal of the first joystick 5 to determine the initial consonant in the initial consonant page;

[0083] Receiving the operation signal of the second button 2 to switch the final consonant page, and receiving the operation signal of the second joystick 6 to determine the final consonant in the final consonant page;

[0084] Receiving the pinyin confirmation signal of the third button 3, generating candidate Chinese characters according to the determined initial consonant and final consonant, and inputting the selected Chinese character according to the operation signals of the cross key 7 and the fourth button 4.

[0085] Next, based on the specific example scheme of this application, a difference embodiment between the technical scheme of this application and the traditional full English keyboard input will be demonstrated. Through specific input scenario comparison, the improvements of this invention in terms of efficiency and operation logic will be shown:

[0086] Input scenario: Take "快乐" (pinyin: kuaile) as an example

[0087] As Figure 11 shown, in the currently common full English keyboard input interface, by moving the direction keys of the gamepad, select the six pinyin letters k, u, a, i, l, e one by one in sequence. Each letter corresponds to an independent position on the keyboard. If the default initial cursor is on the letter Q, a total of 34 cursor movements are required to input "kuaile", and then enter the Chinese character selection.

[0088] As Figure 12 shown, Figure 12 The schematic diagram of the initial consonant and final consonant selection interface based on gamepad operation provided for a specific implementation of this application. Under the logic of the technical scheme of this application, the pinyin is disassembled into two parts: the initial consonant (k) and the final consonant (uai). Quickly locate the initial consonant through the first button 1 + the first joystick 5, and locate the final consonant through the second button 2 + the second joystick 6, and directly splice them into a complete pinyin. For example: To select the initial consonant "k": Press the first button 1 of the gamepad 2 times to switch to the second page of the initial consonant table, and move the first joystick 5 1 time to select "k"; To select the final consonant "uai": Press the second button 2 of the gamepad 3 times to turn to the third page of the final consonant table, and move the second joystick 6 1 time to select "uai"; Only two button presses for page turning + two joystick movements are required to complete the input of "kuai". Compared with the traditional gamepad input method, the technical scheme of this application highlights the target character in real time through joystick movement, and releases the joystick to confirm the selection, without moving the cursor grid by grid. For example, when selecting the final consonant "e", directly push the second joystick 6 to the corresponding position to select it, without cycling through the cross key 7.

[0089] See Figure 13 , Figure 13 This is a schematic diagram of the pinyin input process provided for a specific implementation of this application. The initial consonant display area 110, final vowel display area 210, pinyin candidate area 310, Chinese character candidate area 410, and text input box 510 in this application's technical solution are displayed independently, allowing users to intuitively see the input progress and results. For example, when inputting "le", the Chinese character candidate area 410 simultaneously retains the candidate characters for the preceding "kuai", facilitating multi-word combination input; and the pinyin candidate area 310 displays the selected initial consonant / final vowel in real time (e.g., "k" is displayed when "k" is selected, and "kuai" is displayed after selecting "uai"), while the matching Chinese character is simultaneously displayed in the Chinese character candidate area 410. Users can also adjust the pinyin midway (e.g., if no target character is found for "kuai", the second main button 10 can be pressed directly to delete the final vowel and reselect "ai").

[0090] Therefore, the technical solution of this application, through three core designs—a phonetic-semantic separation input model, functional partitioning of combination buttons, and a multi-area real-time interactive interface—completely changes the inefficient mode of traditional gamepads that rely on letter-by-letter input via an English keyboard. Compared with the traditional method, its operation steps are further simplified, and input efficiency is greatly improved. It is especially suitable for the rapid text input needs of gamepad users in scenarios such as games and mobile devices, significantly reducing the cost of misoperation and optimizing the user experience.

[0091] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
