When the second touch operation is a touch operation for the second control, in response to the second touch operation, a second touch track corresponding to the second touch operation is displayed in the second control.

In this solution, after the second control displays the first touch track, the user can continue to input a second touch operation for the second control to the electronic device to perform subsequent writing. In response to the second touch operation, the electronic device can continue to display the second touch track corresponding to the second touch operation in the second control.

In combination with the first aspect, in a possible design, the first control is determined to be the focus control based on the coordinates of the first touch track. It is detected that the electronic device requests to call the input method service, and it is determined that the electronic device enters the handwriting input mode.

Furthermore, in this solution, if the electronic device determines the first control as the focus control, even if the first control is not a standard input control that is compatible with the global handwriting function of the electronic device, the electronic device can determine whether to enter the handwriting input mode based on whether to request to call the input method service. That is, the method provided in the embodiment of the present application does not require the first control to be compatible with the global handwriting function of the electronic device, and the electronic device can also enter the handwriting input mode, and the user can directly write in the first control to complete the input to the electronic device.

In combination with the first aspect, in a possible design, before determining that the first control is a focus control based on the coordinates of the first touch track, a focus window is determined in at least one window passed by the first touch track based on the coordinates of the first touch track. The first control in the focus window is determined as the focus control, wherein the first touch track passes through at least one control in the focus window, and the at least one control includes the first control.

After the electronic device determines the focus window and/or the focus control, it can make a corresponding response.

In combination with the first aspect, in a possible design, based on the coordinates of the first touch track, the first or last window passed by the first touch track is determined as the focus window. Based on the coordinates of the first touch track, the first control in the focus window is determined as the focus control, and the first control is the first or last control passed by the first touch track in the focus window.

In this solution, the first touch track may pass through multiple focus windows, and the first touch track may also pass through multiple focus controls. The electronic device can determine the first or last window passed by the first touch track as the focus window, and determine the first control passed by the first touch track in the focus window as the focus control, providing multiple implementations for the electronic device to determine the focus window and determine the focus control.

A first touch operation input to the first control is received, and in response to the first touch operation, the displayed interface is switched from the first interface to the second interface, and the second control is determined as a new focus control.

In this solution, even if the first control is determined as the focus control, it will trigger the display interface of the electronic device to switch. That is, the interface displayed by the electronic device switches from the first interface to the second interface. The electronic device will also replace the first control with the second control included in the second interface as the new focus control. The user can continue to write in the second control.

In combination with the first aspect, in a possible design, after the first touch track corresponding to the first touch operation is displayed on the second interface, a second touch operation based on the second interface input is received.

If it is detected that the electronic device requests to call the input method service, it is determined that the electronic device enters the handwriting input mode. If the electronic device enters the handwriting input mode and the second touch operation is a sliding operation, the second touch track is displayed in the switched focus control based on the coordinates of the second touch track.

In this solution, on the basis of the focus control displaying the first touch track, if the user continues to input the second touch operation to the electronic device, and the second touch operation input by the user triggers the focus control to switch, it can be determined whether the electronic device enters the handwriting input mode based on whether the electronic device requests to call the input method service. If the electronic device enters the handwriting input mode, and the second touch operation is a sliding operation, the second touch track is displayed in the switched focus control based on the coordinates of the second touch track, so as to more intuitively show the second touch track to the user.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. In the description of the embodiments of the present application, unless otherwise specified, "/" means or, for example, A/B can mean A or B; "and/or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and/or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this embodiment, unless otherwise specified, "plurality" means two or more.

For ease of understanding, some examples of concepts related to the embodiments of the present application are provided for reference, as shown below:

String: A sequence of at least one of words, numbers, letters, symbols, etc. For example, the string "你好123".

Input control: It can be a control used to implement string input. The input control can be included in the interface or window of various applications displayed by the electronic device.

Candidate content: content displayed in the interface of the input method application for user selection. Candidate content is usually associated with content input by the user into the electronic device through the input method application. Candidate content may include at least one candidate word, wherein the candidate word may be a word (such as "you", "hello", etc.), a punctuation mark (such as "!", "?", etc.), or a number (such as "1", "13", etc.), etc., and this application does not impose any restrictions.

Input method applications are software used to implement character string input in electronic devices such as mobile phones. Most input method applications have a handwriting input function, and users can directly write characters or character strings on the display screen of the electronic device to input corresponding content into the electronic device.

In a related technology, referring to FIG1 , when the input method application starts the handwriting input function, the user can click or select the input control 101 displayed by the electronic device. After the electronic device detects the user's click or selection operation on the input control 101, it can request to call the input method service to pull up the input method window 102 corresponding to the input method application in the displayed interface. The input method window 102 includes a handwriting board 103 for receiving the user's written content. The user can write the corresponding content by touching the handwriting board 103. After the electronic device recognizes the content written by the user on the handwriting board 103, it can display multiple candidate words associated with the content written by the user in the display box 104. After the electronic device detects that the user clicks or selects the candidate word, the candidate word selected by the user can be filled into the input control 101 as the written content input by the user to the electronic device.

It can be seen that when a user inputs written content into an electronic device in the above manner, it is necessary to interact with the electronic device multiple times, which is cumbersome and has low input efficiency.

In a related technology, the electronic device also has a global handwriting function. The user can perform a touch operation in a standard input control to write corresponding content. Among them, the standard input control is an input control adapted to the global handwriting function of the electronic device. After the electronic device detects the user's touch operation on the standard input control, it can trigger the global handwriting function to enter the handwriting input mode. Afterwards, the electronic device can fill the recognized content written by the user in the standard input control into the standard input control.

However, standard input controls usually exist in the application interface corresponding to the application that comes with the electronic device. The input controls included in the application interface corresponding to some third-party applications are mostly ordinary input controls. Ordinary input controls cannot adapt to the global handwriting function of the electronic device. Therefore, when the electronic device detects the user's touch operation on the ordinary input control, it will regard the touch operation as a click operation and make a corresponding response.

In a related technology, referring to FIG2A , when a user performs a touch operation on an input control 201, which triggers a switch in the display interface of the electronic device, if the user performs a touch operation for writing a character string on the input control 201 and/or around the input control 201, for example, the user enters the first stroke of the written content on the input control 201 and/or around the input control 201. Regardless of whether the input control 201 is a standard input control, the electronic device will recognize the touch operation input by the user on the input control 201 and/or around the input control 201 as a click operation, and switch the currently displayed interface to the input interface 202 shown in FIG2B or to the input interface 203 shown in FIG2C.

2B , the input interface 202 includes an input control 204 for receiving user's written content. In the case where the input control 204 is a standard input control, the user can re-enter the written content in the input control 204 and/or around the input control 204. For example, the user enters the first stroke of the written content in the input control 204 and/or around the input control 204. After the electronic device recognizes the content written by the user in the input control 204 and/or around the input control 204, the recognized content can be filled into the input control 204 as the written content input by the user to the electronic device.

Referring to FIG. 2C , the input interface 203 includes an input method window 205. The input method window 205 includes a handwriting board 206 for receiving the user's written content. The user can re-enter the written content on the input control or the handwriting board 206. For example, the user can re-enter the first stroke of the written content on the handwriting board 206. After the electronic device recognizes the content written by the user on the handwriting board 206, a plurality of candidate words associated with the user's written content can be displayed in the display box 207. After the electronic device detects that the user clicks or selects a candidate word, the candidate word selected by the user can be filled into the input control 208 as the written content input by the user to the electronic device.

However, when the user inputs written content to the electronic device in the above manner, if the user's touch operation on the input control triggers the display interface of the electronic device to switch, the electronic device will lose the touch track corresponding to the touch operation after the interface switches. Therefore, the user needs to perform the same touch operation on the electronic device at least twice.

The handwriting input method provided in the embodiment of the present application can be applied to an electronic device. In the method, a user can write on the electronic device by inputting a touch operation related to writing to the electronic device. Based on the user's touch operation, the electronic device can request to call an input method service and enter a handwriting input mode. And, the touch track corresponding to the touch operation can be displayed. After the electronic device enters the handwriting input mode, the user does not need to repeatedly input the touch operation to the electronic device, but can continue to input new touch operations to the electronic device based on the touch track corresponding to the touch operation displayed by the electronic device to write on the electronic device. The method provided in the embodiment of the present application can reduce the number of times a user interacts with an electronic device, thereby improving input efficiency.

Exemplarily, the electronic device in the embodiments of the present application can be a portable computer (such as a mobile phone, a foldable screen mobile phone), a tablet computer, a laptop computer, a personal computer (PC), a wearable electronic device (such as a smart watch), an augmented reality (AR) device, a virtual reality (VR) device, a car computer, etc. The following embodiments do not impose any special restrictions on the specific form of the electronic device.

FIG. 3A shows a schematic structural diagram of the electronic device 100 .

The electronic device 100 may include a processor 110, an external memory interface 120, an internal memory 121, a universal serial bus (USB) interface 130, a charging management module 130, a power management module 131, a battery 132, an antenna 1, an antenna 2, a mobile communication module 150, a wireless communication module 160, an audio module 170, a sensor module 180, a button 190, a motor 191, an indicator 192, a camera 193, a display screen 194, and a subscriber identification module (SIM) card interface 195, etc.

It is to be understood that the structure illustrated in the embodiment of the present invention does not constitute a specific limitation on the electronic device 100. In other embodiments of the present application, the electronic device 100 may include more or fewer components than shown in the figure, or combine some components, or separate some components, or arrange the components differently. The components shown in the figure may be implemented in hardware, software, or a combination of software and hardware.

The processor 110 may include one or more processing units, for example, the processor 110 may include an application processor (AP), a modem processor, a graphics processor (GPU), an image signal processor (ISP), a controller, a memory, a video codec, a digital signal processor (DSP), a baseband processor, and/or a neural-network processing unit (NPU), etc. Different processing units may be independent devices or integrated into one or more processors.

The controller may be the nerve center and command center of the electronic device 100. The controller may generate an operation control signal according to the instruction operation code and the timing signal to complete the control of fetching and executing instructions.

The processor 110 may also be provided with a memory for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. The memory may store instructions or data that the processor 110 has just used or cyclically used. If the processor 110 needs to use the instruction or data again, it may be directly called from the memory. This avoids repeated access, reduces the waiting time of the processor 110, and thus improves the efficiency of the system.

In some embodiments, the processor 110 may include one or more interfaces. The interface may include an inter-integrated circuit (I2C) interface, an inter-integrated circuit sound (I2S) interface, a pulse code modulation (PCM) interface, a universal asynchronous receiver/transmitter (UART) interface, a mobile industry processor interface (MIPI), a general-purpose input/output (GPIO) interface, a subscriber identity module (SIM) interface, and/or a universal serial bus (USB) interface, etc.

The electronic device 100 implements the display function through a GPU, a display screen 194, and an application processor. The GPU is a microprocessor for image processing, which connects the display screen 194 and the application processor. The GPU is used to perform mathematical and geometric calculations for graphics rendering. The processor 110 may include one or more GPUs that execute program instructions to generate or change display information.

The display screen 194 is used to display images, videos, etc. For example, when the electronic device enters the handwriting input mode, the display screen 194 can display the touch track corresponding to the touch operation input by the user to the electronic device.

The display screen 194 includes a display panel. The display panel may be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), Miniled, MicroLed, Micro-OLED, a quantum dot light-emitting diode (QLED), etc. In some embodiments, the electronic device 100 may include 1 or N display screens 194, where N is a positive integer greater than 1.

The external memory interface 120 can be used to connect an external memory card, such as a Micro SD card, to expand the storage capacity of the electronic device 100. The external memory card communicates with the processor 110 through the external memory interface 120 to implement a data storage function, such as storing music, video and other files in the external memory card.

The internal memory 121 can be used to store computer executable program codes, which include instructions. The processor 110 executes various functional applications and data processing of the electronic device 100 by running the instructions stored in the internal memory 121. The internal memory 121 may include a program storage area and a data storage area. Among them, the program storage area may store an operating system, an application required for at least one function (such as a sound playback function, a text input function, an image playback function, etc.), etc. The data storage area may store data created during the use of the electronic device 100 (such as audio data, a thesaurus, a phone book, etc.), etc. In addition, the internal memory 121 may include a high-speed random access memory, and may also include a non-volatile memory, such as at least one disk storage device, a flash memory device, a universal flash storage (UFS), etc.

The sensor module 180 may include a touch sensor 180K. The touch sensor 180K is also called a "touch panel". The touch sensor 180K may be disposed on the display screen 194, and the touch sensor 180K and the display screen 194 form a touch screen, also called a "touch screen". The touch sensor 180K is used to detect a touch operation on or near it.

For example, the touch sensor 180K may detect a touch operation performed by a user on the display screen 194 using a finger or a tool such as a stylus pen.

When the touch sensor 180K detects a touch operation, it can transmit the detected touch operation to the processor to determine relevant information of the touch event. The processor can also control the display screen 194 to provide visual output related to the touch operation. In other embodiments, the touch sensor 180K can also be set on the surface of the electronic device 100, which is different from the position of the display screen 194.

For example, in the embodiment of the present application, the touch sensor 180K can be used to detect the user's touch operation on a specific control and/or around the control, and transmit the detected touch operation to the processor. The processor receives the touch operation sent by the touch sensor 180K and can determine whether the electronic device enters the handwriting input mode based on whether the electronic device requests to call the input method service.

When the handwriting input method in the embodiment of the present application is implemented based on the electronic device 100 shown in FIG. 3A, the touch sensor 180K detects the touch operation input by the user and can pass the detected touch operation to the processor 110. The processor 110 can determine the focus control based on the coordinates of the touch track corresponding to the touch operation. Afterwards, the processor 110 can detect whether the electronic device requests to call the input method service. In the case where the processor 110 determines that the electronic device requests to call the input method service, the processor can control the electronic device to enter the handwriting input mode, and control the display screen 194 to display the touch track corresponding to the touch operation.

Furthermore, when the processor 110 enters the handwriting input mode, it can predict the character corresponding to the touch track. Afterwards, the processor 110 can control the display screen 194 to display the predicted character. Compared with the user first interacting with the electronic device to invoke the input method application, and then inputting the corresponding character to the electronic device based on the invoked input method application, the method provided in the embodiment of the present application can reduce the number of times the user interacts with the electronic device, thereby improving the input efficiency.

The software system of the electronic device 100 may adopt a layered architecture, an event-driven architecture, a micro-core architecture, a micro-service architecture, or a cloud architecture. In the embodiment of the present invention, the Android system of the layered architecture is taken as an example to exemplify the software structure of the electronic device 100.

FIG. 3B is a software structure block diagram of the electronic device 100 according to an embodiment of the present invention.

The layered architecture divides the software into several layers, each with clear roles and division of labor. The layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers, from top to bottom: the application layer, the application framework layer, the Android runtime (Android Runtime) and the system library, and the kernel layer.

The application layer can include a series of application packages.

As shown in FIG3B , the application package may include applications such as camera, gallery, calendar, map, WLAN, music, short message, input method application, etc. Each application package may provide different functions for the electronic device when running. For example, when the input method application is running, the electronic device may receive characters or strings input by the user based on the input method application.

In some embodiments, the application layer may further include a handwriting input module. The handwriting input module in the application layer may be a third-party application installed in the electronic device by the user.

Wherein, the handwriting input module can determine whether the touch operation corresponding to the touch track is a click operation or a slide operation when the user's touch track on the electronic device is obtained. And/or, the handwriting input module can control the electronic device to display the touch track when the user's touch track on the electronic device is obtained. And/or, the handwriting input module can predict the character corresponding to the touch track when the user's touch track on the electronic device is obtained, and control the electronic device to display the character, etc.

The application framework layer provides an application programming interface (API) and a programming framework for the applications in the application layer. The application framework layer includes some predefined functions.

As shown in FIG. 3B , the application framework layer may include a window manager, a content provider, a view system, a phone manager, a resource manager, a notification manager, an input management module, a focus management module, and the like.

The window manager is used to manage window programs. The window manager can obtain the display screen size, determine whether there is a status bar, lock the screen, capture the screen, etc.

Content providers are used to store and retrieve data and make it accessible to applications. The data may include videos, images, audio, calls made and received, browsing history and bookmarks, phone books, etc.

The view system includes visual controls, such as controls for displaying text, controls for displaying images, etc. The view system can be used to build applications. A display interface can be composed of one or more views. For example, a display interface including a text notification icon can include a view for displaying text and a view for displaying images.

The phone manager is used to provide communication functions of the electronic device 100, such as management of call status (including connecting, hanging up, etc.).

The resource manager provides various resources for applications, such as localized strings, icons, images, layout files, video files, and so on.

The notification manager enables applications to display notification information in the status bar, which can be used to convey notification-type messages and disappear automatically after a short stay without user interaction.

The input management module can cache the coordinates of the touch track corresponding to the touch operation when a touch operation input by the user is detected. And/or, the input management module can be used to detect whether the electronic device requests to call the input method service, so as to determine whether the electronic device enters the handwriting input mode. And/or, the input management module can be used to determine whether the user's touch operation is a click operation or a slide operation, etc.

The focus management module is used to determine the focus window when the touch track of the user on the electronic device is acquired. And/or, the focus management module is used to determine whether there is a focus control when the focus window is determined.

In some embodiments, the application framework layer may further include a handwriting input module. The handwriting input module in the application framework layer may be a module provided in the software system of the electronic device. The description of the handwriting input module in the application framework layer may refer to the description of the handwriting input module in the application layer, and will not be repeated here.

Android Runtime includes core libraries and virtual machines. Android Runtime is responsible for scheduling and management of the Android system.

The core library consists of two parts: one part is the function that needs to be called by the Java language, and the other part is the Android core library.

The application layer and the application framework layer run in a virtual machine. The virtual machine executes the Java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform functions such as object life cycle management, stack management, thread management, security and exception management, and garbage collection.

The system library may include multiple functional modules, such as surface manager, media library, 3D graphics processing library (such as OpenGL ES), 2D graphics engine (such as SGL), etc.

The surface manager is used to manage the display subsystem and provide the fusion of 2D and 3D layers for multiple applications.

The media library supports playback and recording of a variety of commonly used audio and video formats, as well as static image files, etc. The media library can support a variety of audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, compositing, and layer processing.

A 2D graphics engine is a drawing engine for 2D drawings.

The kernel layer is the layer between hardware and software. The kernel layer contains at least display driver, camera driver, audio driver, and sensor driver.

Exemplarily, the technical solutions involved in the following embodiments can all be implemented in an electronic device having the above hardware architecture and/or the above software architecture. The handwriting input method provided in the embodiments of the present application is described in detail below in conjunction with the accompanying drawings and handwriting input scenarios.

The interface displayed by the electronic device may include multiple windows, and each window may include multiple controls. For example, referring to FIG. 4A , the interface displayed by the electronic device includes window 400. Window 400 is superimposed with windows 410, 420, and 430. Window 410 includes controls 411 and 412. Window 420 includes controls 421. Window 430 includes controls 431, 432, and 433.

In some embodiments, a user may perform a touch operation on a display screen of an electronic device to input a touch track to the electronic device. When the electronic device detects a touch operation of the user, it may obtain the coordinates of the touch track. Based on the coordinates of the touch track, the electronic device may determine a focus window in at least one window through which the touch track passes. Also, when the touch track passes through at least one control in the focus window, the electronic device may determine a focus control in at least one control through which the touch track passes in the focus window.

The coordinates of the touch track may include the starting point coordinates, the ending point coordinates, and the point coordinates of a preset number of touch points that the touch track passes through between the starting point coordinates and the ending point coordinates.

In some embodiments, the electronic device may obtain the starting coordinates of the touch track and determine the window where the starting coordinates of the touch track are located as the focus window. Afterwards, the electronic device may detect whether the touch track passes through at least one control in the focus window.

If the touch track passes through at least one control in the focus window, the electronic device can obtain the point coordinates of the touch track when it passes through the first control in the focus window. Afterwards, the electronic device can determine the control where the point coordinates are located as the focus control. Alternatively, if the touch track passes through at least one control in the focus window, the electronic device can obtain the point coordinates of the touch track when it passes through the last control in the focus window. Afterwards, the electronic device can determine the control where the point coordinates are located as the focus control.

If the touch track does not pass through any control in the focus window, the electronic device can determine that there is no focus control in the currently displayed interface.

Exemplarily, continue to refer to FIG. 4A. The user performs a touch operation on the display screen of the electronic device to input a touch track to the electronic device. The touch track passes through window 400, window 410, and window 420. When the electronic device detects the user's touch operation, it can obtain the starting point coordinates of the touch track corresponding to the touch operation. Since the starting point coordinates of the touch track are located in window 400, the electronic device can determine window 400 as the focus window.

Afterwards, the electronic device may detect whether the touch track passes through a control in the window 400. Since the touch track does not pass through any control in the window 400, the electronic device may determine that there is no focus control in the currently displayed interface.

For example, see FIG4B. The user performs a touch operation on the display screen of the electronic device to input a touch track to the electronic device. The touch track passes through window 440, window 450, and window 460. When the electronic device detects the user's touch operation, it can obtain the starting point coordinates of the touch track corresponding to the touch operation. Since the starting point of the touch track is located in window 440, the electronic device can determine window 440 as the focus window.

Afterwards, the electronic device may detect whether the touch track passes through the controls in window 440 .

Since the touch track passes through control 441 and control 442 in window 440, and the electronic device can determine that the first control that the touch track passes through in window 440 is control 441 based on the coordinates of the touch track. Therefore, the electronic device can determine control 441 as the focus control. Alternatively, since the touch track passes through control 441 and control 442 in window 440, and the electronic device can determine that the last control that the touch track passes through in window 440 is control 442 based on the coordinates of the touch track. Therefore, the electronic device can determine control 442 as the focus control.

In some embodiments, the electronic device may obtain the coordinates of the end point of the touch track, and determine the window where the coordinates of the end point of the touch track are located as the focus window. Afterwards, the electronic device may detect whether the touch track passes through at least one control in the focus window.

If the touch track passes through at least one control in the focus window, the electronic device can obtain the point coordinates of the touch track when it passes through the first control in the focus window. Afterwards, the electronic device can determine the control where the point coordinates are located as the focus control. Alternatively, if the touch track passes through at least one control in the focus window, the electronic device can obtain the point coordinates of the touch track when it passes through the last control in the focus window. Afterwards, the electronic device can determine the control where the point coordinates are located as the focus control.

If the touch track does not pass through any control in the focus window, and the electronic device determines a control as the focus control before detecting the user's touch operation, the electronic device may still determine the previously determined control as the focus control after detecting the user's touch operation.

If the touch track does not pass through any control in the focus window, and the electronic device determines that there is no focus control in the displayed interface before detecting the user's touch operation, then the electronic device still determines that there is no focus control in the displayed interface after detecting the user's touch operation.

It is understandable that at the same time, the electronic device can only include one focus window, or the electronic device can only include one focus window and one focus control. As the electronic device acquires the user's touch track each time, each control displayed by the electronic device may successively become a focus control, and each window displayed by the electronic device may successively become a focus window.

Exemplarily, referring to FIG. 4C , the user performs a touch operation on the display screen of the electronic device to input a touch track to the electronic device. Since the touch tracks are all located in the control 471, and the control 471 is located in the window 470, the electronic device can determine the control 471 as the focus control based on the coordinates of the touch track. And the electronic device can determine the window 470 as the focus window based on the coordinates of the touch track.

Continuing to refer to Figure 4C, after control 471 is determined as the focus control and window 470 is determined as the focus window. If the user performs a touch operation on the display screen of the electronic device again, after the electronic device obtains the touch track corresponding to the touch operation, since the touch track is located in control 481, and control 481 is located in window 480. Therefore, the electronic device can determine control 481 as the focus control based on the coordinates of the touch track. And, the electronic device can determine window 480 as the focus window based on the coordinates of the touch track. At this time, control 471 is no longer determined as the focus control, and window 470 is no longer determined as the focus window. That is, both the focus control and the focus window are switched.

Continuing to refer to Figure 4D, after control 491 is determined as the focus control and window 490 is determined as the focus window. If the user performs a touch operation on the display screen of the electronic device again, after the electronic device obtains the touch track corresponding to the touch operation, since the touch track is located in control 492, and control 492 is located in window 490. Therefore, the electronic device can determine control 492 as the focus control based on the coordinates of the touch track. And, the electronic device can determine window 490 as the focus window based on the coordinates of the touch track. At this time, control 491 is no longer determined as the focus control, but window 490 is still determined as the focus window. That is, the focus control is switched, and the focus window is not switched.

Based on the above examples, it can be seen that when the focus control switches, the focus window does not necessarily switch. However, when the focus window switches, the focus control switches.

In some embodiments, after detecting the touch track input by the user, the electronic device can determine whether there is a focus control. If there is a focus control, the electronic device can determine whether the focus control is switched.

The electronic device may determine whether the focus control is switched in the following manner:

The electronic device can determine whether the focus control is switched based on whether the focus control determined after detecting the touch track of the user input and the focus control determined before detecting the touch track of the user input are the same control. If they are the same control, it can be determined that the focus control has not been switched. If they are not the same control, it can be determined that the focus control has been switched.

Alternatively, if the electronic device detects that there is no focus control in the interface displayed before the user inputs the touch track, but there is a focus control in the interface displayed after the user inputs the touch track, the electronic device can determine that the focus control is switched.

In some embodiments, when determining that the focus control is switched, the electronic device can determine whether to enter the handwriting input mode based on whether the input method service is requested to be called. If the electronic device requests to call the input method service, the electronic device enters the handwriting input mode. If the electronic device does not request to call the input method service, the electronic device does not enter the handwriting input mode.

For example, before the electronic device determines that the focus control is switched, the electronic device has entered the handwriting input mode. After the electronic device determines that the focus control is switched, if the electronic device does not request to call the input method service, the electronic device exits the handwriting input mode.

If the electronic device does not enter the handwriting input mode before the electronic device determines that the focus control is switched, then after the electronic device determines that the focus control is switched, if the electronic device does not request to call the input method service, the electronic device still does not enter the handwriting input mode.

For another example, before the electronic device determines that the focus control has switched, the electronic device has entered the handwriting input mode. After the electronic device determines that the focus control has switched, if the electronic device requests to call the input method service, the electronic device still remains in the handwriting input mode.

If the electronic device does not enter the handwriting input mode before the electronic device determines that the focus control is switched, then after the electronic device determines that the focus control is switched, if the electronic device requests to call the input method service, the electronic device enters the handwriting input mode.

It can be seen that in the method provided in the embodiment of the present application, when the electronic device detects that the user performs a touch operation on a certain control, even if the control is not a standard input control that is compatible with the global handwriting function of the electronic device, the electronic device can determine whether to enter the handwriting input mode based on whether to request to call the input method service. That is, the method provided in the embodiment of the present application does not require the input control of the third-party application to be compatible with the global handwriting function of the electronic device, and the electronic device can also enter the handwriting input mode, and the user can directly write in the input control of the third-party application to complete the input to the electronic device.

In some embodiments, each time the user touches the display screen of the electronic device and stops touching the display screen of the electronic device is considered as a touch operation. During each touch operation performed by the user on the electronic device, if the electronic device detects that the user stops touching the display screen of the electronic device, it is determined that the user has ended the touch operation.

The touch operation performed by the user on the display screen of the electronic device may include a click operation and a slide operation. The electronic device may determine whether the touch operation of the user is a click operation or a slide operation based on the coordinates of the acquired touch track.

Referring to (a) in FIG. 5 , a user can click a certain position on the display screen with a finger or a tool such as a stylus pen to perform a click operation on the display screen of the electronic device. When the user performs the click operation, the touch track 501 input to the electronic device is in the form of a point. Therefore, if the number of point coordinates included in the coordinates of the touch track acquired by the electronic device is less than a preset number (for example, less than 2), the electronic device can determine that the user's touch operation is a click operation.

Referring to (b) in FIG. 5 , the user can move a finger or a tool such as a stylus pen while keeping the finger or a tool such as a stylus pen in contact with the display screen to perform a sliding operation on the display screen of the electronic device. When the user performs the sliding operation, the touch track 502 input to the electronic device is linear. Therefore, if the number of point coordinates included in the coordinates of the touch track acquired by the electronic device is greater than or equal to a preset number (for example, greater than 2), the electronic device can determine that the user's touch operation is a sliding operation.

In some embodiments, when the electronic device enters the handwriting input mode in response to a user's touch operation, if the electronic device determines that the touch operation is a sliding operation, the electronic device may display the touch track corresponding to the touch operation based on the coordinates of the touch track corresponding to the touch operation, thereby more intuitively showing the touch track to the user. If the electronic device determines that the touch operation is a click operation, the electronic device may not display the touch track corresponding to the click operation, thereby saving the running memory of the electronic device.

For example, see Figure 6A. The user can perform a touch operation on control 601 and/or around control 601. After the electronic device detects the user's touch operation, it can determine control 601 as the focus control and request to call the input method service. Since the electronic device requests to call the input method service, the electronic device can enter the handwriting input mode. Afterwards, when the electronic device determines that the user's touch operation is a sliding operation, the electronic device can display the touch track on control 601 and/or around control 601 based on the coordinates of the touch track corresponding to the sliding operation.

In some embodiments, after the electronic device displays a touch track (also referred to as a first touch track in the embodiment of the present application) corresponding to a user's touch operation (also referred to as a first touch operation in the embodiment of the present application), if the user continues to input a touch operation (also referred to as a second touch operation in the embodiment of the present application) to the electronic device. After detecting the user's second touch operation, the electronic device can detect whether the focus control is switched.

If the focus control does not switch, the electronic device can display the touch track corresponding to the second touch operation (which may also be referred to as the second touch track in the embodiment of the present application).

If the focus control switches, the electronic device can refer to the description in the above embodiment, and re-determine whether the electronic device enters the handwriting input mode based on whether the electronic device requests to call the input method service, and make a corresponding response.

In some embodiments, the electronic device may predict at least one character corresponding to the first touch track and/or the second touch track based on the coordinates of the first touch track and/or the coordinates of the second touch track. Afterwards, the electronic device may display the target character in the at least one character in the focus control.

The target characters may include a first target character, a second target character, and a third target character. The first target character may be a character corresponding to the first touch track obtained based on the coordinates of the first touch track. The second target character may be a character corresponding to the first touch track and the second touch track obtained based on the coordinates of the first touch track and the coordinates of the second touch track. The third target character may be a character corresponding to the second touch track obtained based on the coordinates of the second touch track.

In some embodiments, the target character may be the character with the highest degree of matching with the first touch track and/or the second touch track. For example, the first target character may be the character with the highest degree of matching with the first touch track. The second target character may be the character with the highest degree of matching with the first touch track and the second touch track. The third target character may be the character with the highest degree of matching with the second touch track.

Exemplary, continue to refer to Figure 6A. The user inputs a first touch operation for the control 601 to the electronic device, and the electronic device can display a first touch track "一" along with the first touch operation input by the user. Afterwards, the user can continue to input a second touch operation for the control 601 to the electronic device, and the electronic device can display a second touch track "丿" along with the second touch operation input by the user. Based on the coordinates of the first touch track and the coordinates of the second touch track, the electronic device can predict at least one character corresponding to the first touch track and the second touch track (for example, obtain the characters "厂", "T", "尸", etc.). Afterwards, the electronic device can display the character with the highest matching degree with the first touch track and the second touch track in the control 601 (for example, display the character "厂").

In some embodiments, referring to FIG6B , the target character may be a character selected by the user. After the electronic device predicts at least one character corresponding to the first touch track and/or the second touch track based on the coordinates of the first touch track and/or the coordinates of the second touch track, it may also display a display frame 602. Display frame 602 includes at least one character predicted by the electronic device. The user may click or select the target character in at least one character. After the electronic device detects the user's click or selection operation on the target character, the target character may be displayed in the focus control 603.

In some embodiments, the electronic device may predict at least one character corresponding to the first touch track and/or the second touch track through an input method application. Afterwards, the electronic device may pull up an input method window corresponding to the input method application. The input method window includes a display box displaying at least one character predicted by the input method application. The user may click or select the target character in the display box to input the character into the focus control.

The embodiment of the present application takes the example of a user inputting a first touch operation and/or a second touch operation for a focus control to an electronic device, and exemplifies a method for an electronic device to obtain characters corresponding to a first touch trajectory and/or a second touch trajectory. In actual applications, after the user inputs a second touch operation for a focus control to the electronic device, the user may continue to input a third touch operation, a fourth touch operation, and other more touch operations for the focus control to the electronic device. After detecting the third touch operation, the fourth touch operation, and other more touch operations input by the user, the electronic device may display more touch trajectories, such as a third touch trajectory corresponding to the third touch operation, a fourth touch trajectory corresponding to the fourth touch operation, and so on. Based on these touch trajectories, the electronic device may predict the corresponding characters.

In some embodiments, when the electronic device enters the handwriting input mode in response to the user's touch operation and switches the displayed interface from the first interface to the second interface, if the electronic device determines that the touch operation is a sliding operation, the electronic device may determine the touch operation as a first touch operation and display the first touch track corresponding to the first touch operation in the second interface, thereby more intuitively showing the first touch track to the user. If the electronic device determines that the touch operation is a click operation, the electronic device may not display the touch track corresponding to the click operation, thereby saving the running memory of the electronic device.

In some embodiments, the first interface may include a first control, and the second interface may include a second control. The first control is associated with the second control. The association of the first control with the second control means that if the electronic device determines that the first control is the focus control, the displayed interface can be switched from the first interface to the second interface, and the second control is determined to replace the first control as the new focus control.

For example, referring to FIG. 7 , the user can perform a touch operation on control 701 and/or around control 701. Among them, the touch operation performed by the user on control 701 and/or around control 701 will trigger the interface displayed by the electronic device to switch, that is, switch from interface 702 to interface 703. After the electronic device detects the user's touch operation, it can determine control 701 as the focus control. Afterwards, the electronic device can switch the displayed interface from interface 702 to interface 703. After the electronic device displays interface 703, it can determine control 704 in interface 703 as the new focus control.

In some embodiments, if the electronic device detects that the touch operation input by the user to the first control is a sliding operation, the electronic device can determine the touch operation as a first touch operation, and can display a first touch trajectory corresponding to the first touch operation in the second control and/or around the second control.

Exemplarily, referring to FIG. 7 , if the touch operation input by the user in the interface 702 is a sliding operation, the electronic device may determine the user's touch operation as a first touch operation and display a first touch track corresponding to the first touch operation in the control 704 included in the interface 703 .

In some embodiments, when the electronic device displays the first touch track in the second interface, the user does not need to repeatedly input the first touch operation for the focus control in the second interface, but can continue to input subsequent writing content in the second interface, thereby improving writing efficiency.

Exemplarily, referring to FIG. 7 , when the first touch track corresponding to the first touch operation is displayed in the control 704 included in the interface 703, the user can continue to input more touch operations such as the second touch operation in the control 704 and/or around the control 704 to perform subsequent writing. When the electronic device detects more touch operations such as the second touch operation input by the user, it can display more touch tracks such as the second touch track corresponding to the second touch operation.

In some embodiments, the electronic device may predict at least one character corresponding to the touch track input by the user in the first interface and/or the second interface based on the coordinates of the first touch track input by the user in the first interface and/or the coordinates of the second touch track input by the user in the second interface. Afterwards, the electronic device may display the target character in the at least one character in the focus control (e.g., the second control in the above embodiment).

Exemplarily, when the target character is the character with the highest matching degree with the first touch track and/or the second touch track, continue to refer to FIG. 7. The electronic device can predict the target character "人" based on the coordinates of the first touch track corresponding to the first touch operation input by the user on the control 701 and/or around the control 701 and the coordinates of the second touch track corresponding to the second touch operation input by the user on the control 704 and/or around the control 701. Afterwards, the electronic device can display the target character "人" in the control 704.

In some embodiments, when the target character is a character selected by the user, referring to FIG8 , the electronic device may predict at least one character corresponding to the touch track input by the user in the first interface 801 and/or the second interface 802 based on the coordinates of the first touch track corresponding to the first touch operation input by the user in the first interface 801 and/or the coordinates of the second touch track corresponding to the second touch operation input by the user in the second interface 802. Afterwards, the electronic device may display a display box 803. The display box 803 includes at least one character predicted by the electronic device. The user may click or select the target character in the at least one character. After the electronic device detects the user's click or selection operation on the target character, the target character may be displayed in the focus control 804.

In some embodiments, when the electronic device obtains the touch track of the user, it can obtain the attribute of the touch track. The attribute of the touch track may include a first attribute and a second attribute. Among them, when the electronic device detects that the user performs a touch operation on the display screen of the electronic device with a finger, the attribute of the touch track corresponding to the user's touch operation can be determined as the first attribute. When the electronic device detects that the user performs a touch operation on the display screen of the electronic device with a tool such as a stylus, the attribute of the touch track corresponding to the user's touch operation can be determined as the second attribute.

In some embodiments, in order to prevent the user from accidentally touching the display screen of the electronic device, the electronic device may execute the handwriting input method provided in the above-mentioned embodiment of the present application when detecting that the touch track is the second attribute.

In some embodiments, in order to prevent foreign objects from accidentally touching the display screen of the electronic device, the electronic device can execute the handwriting input method provided in the above-mentioned embodiment of the present application when detecting that the touch track is the first attribute.

It is understandable that the electronic device can detect whether the user inputs a touch operation on the electronic device through a finger or a tool such as a stylus based on hardware such as a sensor, thereby determining whether the attribute of the touch track corresponding to the touch operation is the first attribute or the second attribute. This application does not limit the method for how the electronic device determines the attribute of the touch track.

In some schemes, multiple embodiments of the present application can be combined, and the combined scheme can be implemented. Optionally, some operations in the process of each method embodiment are optionally combined, and/or the order of some operations is optionally changed. In addition, the execution order between the steps of each process is only exemplary and does not constitute a restriction on the execution order between the steps. There can also be other execution orders between the steps. It is not intended to indicate that the execution order is the only order in which these operations can be performed. A person of ordinary skill in the art will think of a variety of ways to reorder the operations described herein. In addition, it should be noted that the process details involved in a certain embodiment of this article are also applicable to other embodiments in a similar manner, or different embodiments can be used in combination.

In addition, some steps in the method embodiment may be equivalently replaced by other possible steps. Alternatively, some steps in the method embodiment may be optional and may be deleted in certain usage scenarios. Alternatively, other possible steps may be added to the method embodiment.

Furthermore, the various method embodiments may be implemented separately or in combination.

In combination with the algorithm steps of each example described in the embodiment disclosed herein, the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution.

In this embodiment, the electronic device can be divided into functional modules according to the above method example. For example, each functional module can be divided according to each function, or two or more functions can be integrated into one processing module. The above integrated module can be implemented in the form of hardware. It should be noted that the division of modules in this embodiment is schematic and is only a logical function division. There may be other division methods in actual implementation.

9 , the electronic device 900 provided in the embodiment of the present application includes an input management module 901, a focus management module 902, and a handwriting input module 903. The modules included in the electronic device 900 are described in detail below in conjunction with implementation modes 1 to 3.

Implementation 1:

10 , the input management module 901 detects a first touch operation of the user, caches the coordinates of a first touch track corresponding to the first touch operation, and sends the coordinates of the first touch track to the focus management module 902 .

After receiving the coordinates of the first touch track sent by the input management module 901 , the focus management module 902 determines the focus window based on the coordinates of the first touch track.

When determining the focus window, the focus management module 902 may determine whether there is a focus control based on the coordinates of the first touch track and the focus window.

In the case where the focus management module 902 determines that there is no focus control, the coordinates of the received first touch track may be deleted to release memory space of the electronic device.

When the focus management module 902 determines that there is a focus control, the focus management module 902 may also detect whether the focus control is switched. If the focus management module 902 detects that the focus control is switched, the first information is sent to the input management module 901. The first information is used to inform the input management module 901 that the focus control is switched.

After receiving the first information sent by the focus management module 902, the input management module 901 can detect whether the electronic device requests to call the input method service to determine whether the electronic device enters the handwriting input mode. If the input management module 901 detects that the electronic device requests to call the input method service, it determines that the electronic device enters the handwriting input mode. If the input management module 901 does not detect that the electronic device requests to call the input method service, it determines that the electronic device does not enter the handwriting input mode.

When the input management module 901 determines that the electronic device does not enter the handwriting input mode, the coordinates of the received first touch track may be deleted to release the memory space of the electronic device.

When the input management module 901 determines that the electronic device enters the handwriting input mode, the input management module 901 may determine whether the first touch operation of the user is a click operation or a slide operation based on the cached coordinates of the first touch track.

When the input management module 901 determines that the first touch operation of the user is a click operation, the input management module 901 may delete the cached coordinates of the first touch track to release memory space of the electronic device.

When the input management module 901 determines that the first touch operation of the user is a sliding operation, the coordinates of the cached first touch track may be sent to the handwriting input module 903 .

After receiving the coordinates of the first touch track sent by the input management module 901 , the handwriting input module 903 may control the electronic device to display the first touch track based on the coordinates of the first touch track.

In addition, the handwriting input module 903 can also predict the character corresponding to the first touch track based on the coordinates of the first touch track. Afterwards, the handwriting input module 903 can control the electronic device to display the character and hide the displayed first touch track.

In some embodiments, when the input management module 901 does not detect the switching of the focus control, if the input management module 901 detects the user's second touch operation again, the input management module 901 can send the coordinates of the second touch track corresponding to the second touch operation to the handwriting input module 903. The handwriting input module 903 can continue to predict the character corresponding to the second touch track based on the coordinates of the received second touch track. After that, the handwriting input module 903 can send the predicted character to the input management module 901. After receiving the character sent by the handwriting input module 903, the input management module 901 can control the electronic device to display the character and hide the displayed second touch track.

In some embodiments, the first information also includes an identifier for characterizing the switched focus control determined by the focus management module 902. While the input management module 901 determines that the user's second touch operation is a sliding operation and sends the coordinates of the cached second touch track to the handwriting input module 903, it can also send an identifier for characterizing the switched focus control determined by the focus management module 902 to the handwriting input module 903. The handwriting input module 903 can control the electronic device to display the user's second touch track in the focus control and/or around the focus control based on the received identifier of the focus control. And, the handwriting input module 903 can control the electronic device to display the predicted characters in the focus control and hide the displayed second touch track based on the received identifier of the focus control.

In some embodiments, the input management module 901 detects a user's touch operation (which may be a first touch operation or a second touch operation), and may obtain the attribute of the touch track corresponding to the touch operation. When the electronic device detects that the user is performing a touch operation on the display screen of the electronic device with a finger, the attribute of the touch track corresponding to the user's touch operation may be determined as the first attribute. When the electronic device detects that the user is performing a touch operation on the display screen of the electronic device with a tool such as a stylus, the attribute of the touch track corresponding to the user's touch operation may be determined as the second attribute.

When the input management module 901 determines that the touch track is of the first attribute, the steps in this scenario may continue to be executed, thereby preventing foreign objects from accidentally touching the display screen of the electronic device.

Alternatively, when the input management module 901 determines that the touch track is of the second attribute, the steps in this scenario may continue to be executed, thereby preventing the user from accidentally touching the display screen of the electronic device.

Implementation 2:

11 , in implementation 2, the input management module 901 detects whether the electronic device requests to call the input method service to determine whether the electronic device enters the handwriting input mode. The steps before that can refer to the steps in implementation 1 and are not repeated here.

When the input management module 901 determines that the electronic device does not enter the handwriting input mode, the input management module 901 may delete the received coordinates of the first touch track to release the memory space of the electronic device.

When the input management module 901 determines that the electronic device enters the handwriting input mode, the input management module 901 may send the cached coordinates of the first touch track to the handwriting input module 903 .

After receiving the coordinates of the first touch track sent by the input management module 901 , the handwriting input module 903 may determine whether the first touch operation of the user is a click operation or a slide operation based on the coordinates of the first touch track.

When the handwriting input module 903 determines that the user's first touch operation is a click operation, the second information may be sent to the input management module 901. After receiving the second information, the input management module 901 may delete the cached coordinates of the first touch track to release memory space of the electronic device.

The steps after the handwriting input module 903 determines that the user's first touch operation is a sliding operation can refer to the steps after the handwriting input module 903 receives the coordinates of the first touch track sent by the input management module 901 in implementation mode 1, which will not be repeated here.

Based on the above content, the difference between implementation method 1 and implementation method 2 is:

In implementation mode 1, after the electronic device enters the handwriting input mode, the input management module 901 can determine whether the user's first touch operation is a click operation or a slide operation based on the coordinates of the cached first touch track. The input management module 901 sends the cached coordinates of the first touch track to the handwriting input module 903 only when it determines that the user's first touch operation is a slide operation. In implementation mode 2, after the electronic device enters the handwriting input mode, the input management module 901 directly sends the cached coordinates of the first touch track to the handwriting input module 903. The handwriting input module 903 determines whether the user's first touch operation is a click operation or a slide operation based on the coordinates of the first touch track.

Implementation 3:

12 , the input management module 901 detects a first touch operation of the user, and sends the coordinates of the first touch track to the focus management module 902 and the handwriting input module 903 .

After receiving the coordinates of the first touch track sent by the input management module 901 , the focus management module 902 determines the focus window based on the coordinates of the first touch track.

When determining the focus window, the focus management module 902 may determine whether there is a focus control based on the coordinates of the first touch track and the focus window.

When determining that there is no focus control, the focus management module 902 may delete the received coordinates of the first touch track to release memory space of the electronic device.

When determining that there is a focus control, the focus management module 902 may also detect whether the focus control is switched. If the focus management module 902 detects that the focus control is switched, the first information is sent to the input management module 901. The first information is used to inform the input management module 901 that the focus control is switched.

After receiving the first information sent by the focus management module 902, the input management module 901 can detect whether the electronic device requests to call the input method service to determine whether the electronic device enters the handwriting input mode. If the input management module 901 detects that the electronic device requests to call the input method service, it determines that the electronic device enters the handwriting input mode. If the input management module 901 does not detect that the electronic device requests to call the input method service, it determines that the electronic device does not enter the handwriting input mode.

When the input management module 901 determines that the electronic device does not enter the handwriting input mode, the coordinates of the received first touch track may be deleted to release the memory space of the electronic device.

When the input management module 901 determines that the electronic device enters the handwriting input mode, the third information may be sent to the handwriting input module 903. The third information is used to inform the handwriting input module 903 that the electronic device enters the handwriting input mode.

After receiving the third information sent by the input management module 901, the handwriting input module 903 can determine whether the first touch operation of the user is a click operation or a slide operation based on the coordinates of the first touch track received previously.

The steps after the handwriting input module 903 determines whether the user's first touch operation is a click operation or a slide operation can refer to the steps in implementation method 2, which will not be repeated here.

Based on the above content, the difference between implementation method 2 and implementation method 3 is:

In implementation mode 2, the input management module 901 detects the user's first touch operation and caches the coordinates of the first touch track corresponding to the first touch operation. When the input management module 901 determines that the electronic device has entered the handwriting input mode, the coordinates of the first touch track are sent to the handwriting input module 903. In implementation mode 3, the input management module 901 detects the user's first touch operation, and does not need to cache the coordinates of the touch track corresponding to the first touch operation, but directly sends the coordinates of the first touch track to the handwriting input module 903. The handwriting input module 903 can subsequently directly call the coordinates of the first touch track.
