Abstract
Description
Technical Field
[0001] This invention relates to the field of information technology, and in particular to a virtual keyboard input method, apparatus, electronic device, and readable storage medium. Background Technology
[0002] In a full keyboard setup, adjacent characters (such as from A to B) require one arrow key press, but characters that are far apart (such as from A to Z) require up to eight arrow key presses and one confirmation key press. Although the 3x3 grid setup reduces the number of steps for selecting a region, the three-step operation of "region selection → character expansion → character selection" still requires multiple key presses. While it reduces the number of key presses by about 30% compared to a full keyboard when inputting the same string, it still cannot meet the needs of efficient input.
[0003] Therefore, due to the limited number of basic buttons on remote control devices, the input efficiency of virtual keyboards is relatively low. Summary of the Invention

[0009] In one embodiment, determining the key to be operated from the directional keys of the virtual interface to be operated based on the remote control directional key information includes: If the remote control directional key information is the remote control up key information, then the up key position of the virtual interface to be operated is determined to be the key position to be operated based on the remote control up key information; If the remote control directional key information is the remote control down key information, then the down key position of the virtual interface to be operated is determined as the key position to be operated based on the remote control down key information.

[0012] Secondly, the present invention provides a virtual keyboard input device, comprising: The acquisition module is used to acquire remote control operation information; A response module is used to determine the key to be operated on the current virtual interface to be operated on the display screen according to the remote control operation information, and respond to the key to be operated; wherein, the virtual interface to be operated is a first virtual keyboard interface or a second virtual keyboard interface, the first virtual keyboard interface and the second virtual keyboard interface each include a center key and multiple directional keys, the directional keys include an up key, a down key, a left key and a right key, the center key is a first function key, the up key, the down key, the left key and the right key are all used for inputting characters, the second function key and the third function key are all integrated into the up key or the down key or the left key or the right key, and the intersection of the input character data corresponding to the first virtual keyboard interface and the input character data corresponding to the second virtual keyboard interface is empty.

[0022] Furthermore, the terms "first," "second," and "third" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0023] Unless otherwise specified, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which the various embodiments of the invention pertain. Terms (such as those defined in commonly used dictionaries) shall be interpreted as having the same meaning as in their contextual meaning in the relevant technical field and shall not be interpreted as having an idealized or overly formal meaning, unless clearly defined in the various embodiments of the invention.
[0024] Example 1 This disclosure provides a virtual keyboard input method for achieving efficient and fast character input on a virtual keyboard.
[0025] Please see Figure 1 The virtual keyboard input method includes steps S101 to S102, and each step is described in detail below.
[0026] Step S101: Obtain remote control operation information.
[0027] In this embodiment, the user sends remote control operation information to the display device based on input requirements via a remote control or other remote control device. The display device can be a smart TV, set-top box, or other home audio-visual equipment, compatible with mainstream smart TV operating systems (such as Android TV, Tizen, WebOS) and universal remote control hardware, requiring only up / down / left / right / OK buttons. Communication between the remote control device and the display device can be via standard infrared or Bluetooth.
[0028] Step S102: Determine the key to be operated on the current virtual interface to be operated on the display screen according to the remote control operation information, and respond to the key to be operated; wherein, the virtual interface to be operated is a first virtual keyboard interface or a second virtual keyboard interface, the first virtual keyboard interface and the second virtual keyboard interface each include a center key and multiple directional keys, the directional keys include an up key, a down key, a left key and a right key, the center key is a first function key, the up key, the down key, the left key and the right key are all used to input characters, the second function key and the third function key are all integrated into the up key or the down key or the left key or the right key, and the intersection of the input character data corresponding to the first virtual keyboard interface and the input character data corresponding to the second virtual keyboard interface is empty.
[0029] In this embodiment, the pending key of the virtual interface to be operated on the display screen is determined according to the operation indicated by the remote control operation information, and the pending key is responded to to meet the user's operation needs, thereby obtaining the target string, and then performing processing such as searching based on the target string.
[0030] The virtual interface to be operated is either a first virtual keyboard interface or a second virtual keyboard interface. When the virtual keyboard input function of the display screen is activated, the initial virtual keyboard display interface is the first virtual keyboard interface. The current virtual interface to be operated can be switched between the first virtual keyboard interface and the second virtual keyboard interface through remote control operation information.
[0031] The first and second virtual keyboard interfaces have the same layout, each including a center key and multiple arrow keys.
[0032] The arrow keys include up, down, left, and right keys, with the center key serving as the first function key for indicating function switching. Each of the up, down, left, and right keys is associated with a set of characters for input. The second and third function keys are integrated into the up, down, left, or right keys, respectively, and can be used for functions such as inserting symbols, switching between uppercase and lowercase, backspace, and deletion. Furthermore, the intersection between the input character data on the first and second virtual keyboard interfaces is empty, ensuring that characters and functions do not overlap within the limited number of keys, optimizing character distribution, avoiding redundancy, and thus improving character input efficiency. In addition, integrating function keys into the character grouping process addresses the pain point of "separation of character input and error correction" in traditional solutions, improving operational continuity.
[0033] For examples, please refer to the following: Figure 2 and Figure 3 , Figure 2 Indicates the first virtual keyboard interface, Figure 3 The second virtual keyboard interface is indicated. The blue and red areas are the keys to be selected, and the characters corresponding to each key include letters and numbers.
[0034] It should be noted that the currently entered string (such as "HEL") and the currently selected virtual keyboard (such as "First Virtual Keyboard Interface") are displayed at the bottom of the screen to prevent users from forgetting their input progress.
[0035] In one specific embodiment, the method further includes: analyzing the historical character input data corresponding to the display screen to obtain high-frequency character data and low-frequency character data; and determining the input character data corresponding to the first virtual keyboard interface and the input character data corresponding to the second virtual keyboard interface based on the high-frequency character data and the low-frequency character data, respectively.
[0036] In this embodiment, statistical analysis is performed on the historical character input data records associated with the display device to identify frequently used high-frequency character data and less frequently used low-frequency character data.
[0037] Furthermore, high-frequency characters are prioritized for the arrow keys on the more easily accessible first virtual keyboard interface, while low-frequency characters are assigned to the second virtual keyboard interface. This achieves personalized input path optimization, minimizes the average access cost of frequently used characters, and avoids meaningless virtual keyboard switching.
[0038] Please see Figure 4 In one specific embodiment, step S102 includes steps S401 to S402, and each step is described in detail below.
[0039] Step S401: If the remote control operation information is remote control center key information, the current virtual interface to be operated is the first virtual keyboard interface or the second virtual keyboard interface, and the current virtual interface to be operated does not select the key to be operated, then the center key of the virtual interface to be operated is determined as the key to be operated based on the remote control center key information.
[0040] In this embodiment, if the remote control operation information sent by the user through the remote control device is remote control center key information, that is, the user presses the center key (usually the confirmation key) on the remote control device, and at the same time, the current virtual interface to be operated is the first virtual keyboard interface or the second virtual keyboard interface, and the key to be operated is not selected on the current virtual interface to be operated, then it can be known that the user's current intention is not to input characters, but to switch virtual keyboards. Therefore, the center key of the virtual interface to be operated is determined as the key to be operated based on the remote control center key information.
[0041] Step S402: Switch the current virtual interface to be operated to the candidate virtual keyboard interface by responding to the key to be operated; wherein, if the current virtual interface to be operated is the first virtual keyboard interface, then the candidate virtual keyboard interface is the second virtual keyboard interface; if the current virtual interface to be operated is the second virtual keyboard interface, then the candidate virtual keyboard interface is the first virtual keyboard interface.
[0042] In this embodiment, the current virtual interface to be operated is switched to the candidate virtual keyboard interface by responding to the key to be operated (center key). If the current virtual interface to be operated is the first virtual keyboard interface, then the candidate virtual keyboard interface is the second virtual keyboard interface; if the current virtual interface to be operated is the second virtual keyboard interface, then the candidate virtual keyboard interface is the first virtual keyboard interface. The virtual keyboard switching can be completed with only one center key operation, saving at least 2 to 3 key presses compared to the traditional "back + reselect" method. Therefore, no additional menus or gestures are needed, greatly simplifying the remote control process.
[0043] Please see Figure 5 In one specific embodiment, step S102 includes steps S501 to S502, and each step is described in detail below.
[0044] Step S501: If the remote control operation information is remote control directional key information, and the current virtual interface to be operated is the first virtual keyboard interface or the second virtual keyboard interface, then the key to be operated is determined from each directional key of the virtual interface to be operated according to the remote control directional key information.
[0045] In this embodiment, if the remote control operation information sent by the user through the remote control device is remote control directional key information, and the current virtual interface to be operated is the first virtual keyboard interface or the second virtual keyboard interface, it can be known that the current user's intention is to input and select characters. At this time, the key to be operated is determined from each directional key position of the virtual interface to be operated based on the remote control directional key information.
[0046] It should be noted that if the remote control directional key information is the up button, then the up button of the virtual interface to be operated is determined to be the key to be operated based on the up button information; if the remote control directional key information is the down button, then the down button of the virtual interface to be operated is determined to be the key to be operated based on the down button information; if the remote control directional key information is the left button, then the left button of the virtual interface to be operated is determined to be the key to be operated based on the left button information; and if the remote control directional key information is the right button, then the right button of the virtual interface to be operated is determined to be the key to be operated based on the right button information.
[0047] Step S502, by responding to the key to be operated, a character function list interface is displayed, the character function list interface includes any one of the following features (1) to (4): (1) multiple single character keys; (2) multiple single character keys and the second function key; (3) multiple single character keys and the third function key; (4) multiple single character keys, the second function key and the third function key.
[0048] In this embodiment, upon responding to the key to be operated, the character function list interface corresponding to that key is displayed. Each directional key includes one of the following four forms: (1) Multiple single-character keys (basic character selection); (2) Multiple single-character keys + secondary function keys (such as Shift, Caps Lock); (3) Multiple single-character keys + third function keys (such as @, #, space and other special symbols); (4) Multiple single-character keys + second function keys + third function keys (complete function integration).
[0049] Exemplary, such as Figure 6 As shown, assuming the up key corresponds to the vowel set {F, G, H, I, J}, clicking the up key will bring up five letter options. Other examples also include function options such as "clear" or "back".
[0050] In one specific embodiment, please refer to Figure 7 Step S402 includes steps S701 to S702, and each step is described in detail below.
[0051] Step S701: Obtain the remote control directional key information, and determine the key to be operated from the character function list interface based on the remote control directional key information.
[0052] In this embodiment, after the letter function list interface is displayed, the remote control directional key information is obtained, and the key to be operated is determined from the character function list interface based on the remote control directional key information, which is used to select a certain character or function.
[0053] It should be noted that the key to be operated is selected by moving it up, down, left, or right in the character function list interface based on the remote control directional key information. Specifically, if the remote control directional key information is the up button, it moves up; if it is the down button, it moves down; if it is the left button, it moves left; and if it is the right button, it moves right.
[0054] Step S702: Respond to the key to be operated by obtaining the remote control center key information.
[0055] In this embodiment, after determining the character to be input or the function to be selected, the user presses the center key on the remote control device, and the remote control device sends the remote control center key information, and responds to the selected key to be operated, so as to input the selected character or respond to the function.
[0056] It should be noted that after selecting a key to be operated, the border of that key will be highlighted. Meanwhile, the button response time (the time from pressing the remote control button to receiving feedback on the interface) is controlled within 100ms; the time for the interface characters to update after the virtual keyboard switch confirmation key is triggered is controlled within 50ms; it supports smart TV systems with Android 5.0 and above, Tizen 2.4 and above, and WebOS 3.0 and above; the device must be compatible with infrared remote controls (NEC protocol, RC5 protocol) and Bluetooth remote controls (HID protocol).
[0057] As an example, when it is necessary to input the first letters of different movies and TV shows on the display screen, the comparison of the number of keystrokes for the virtual keyboard input method, the nine-key virtual keyboard input method, and the full keyboard virtual keyboard input method proposed in this embodiment is shown in Table 1: Table 1:
[0058] Furthermore, the comparison results between the virtual keyboard input method proposed in this embodiment and traditional solutions in terms of average keystrokes per character and hardware requirements are shown in Table 2: Table 2:
[0059] The virtual keyboard input method proposed in this embodiment acquires remote control operation information; determines the key to be operated on the current virtual interface to be operated on the display screen according to the remote control operation information, and responds to the key to be operated; wherein, the virtual interface to be operated is a first virtual keyboard interface or a second virtual keyboard interface, the first virtual keyboard interface and the second virtual keyboard interface each include a center key and multiple directional keys, the directional keys include an up key, a down key, a left key and a right key, the center key is a first function key, the up key, the down key, the left key and the right key are all used to input characters, the second function key and the third function key are all integrated into the up key, the down key, the left key or the right key, and the intersection of the input character data corresponding to the first virtual keyboard interface and the input character data corresponding to the second virtual keyboard interface is empty. By setting up two virtual keyboard interfaces with non-overlapping character input data, and using the directional keys for character input and integrating multiple function keys in each virtual keyboard, while retaining the center key as a unified function confirmation entry point, users can achieve efficient and accurate text input on a remote control with only directional navigation capabilities. Compared to traditional virtual keyboard switching methods, this solution significantly shortens the operation path and improves input efficiency; through function reuse and context-aware mechanisms, it expands interactive capabilities without increasing hardware complexity; furthermore, the character set isolation design between keyboards effectively avoids input ambiguity, improving system stability and user experience.
