The pressure sensor 180A is used to sense the pressure signal and can convert the pressure signal into an electrical signal. In some embodiments, the pressure sensor 180A can be set on the display screen 194. There are many types of pressure sensors 180A, such as resistive pressure sensors, inductive pressure sensors, capacitive pressure sensors, etc. The capacitive pressure sensor can be a parallel plate including at least two conductive materials. When a force acts on the pressure sensor 180A, the capacitance between the electrodes changes. The electronic device 100 determines the intensity of the pressure according to the change in capacitance. When a touch operation acts on the display screen 194, the electronic device 100 detects the touch operation intensity according to the pressure sensor 180A. The electronic device 100 can also calculate the touch position according to the detection signal of the pressure sensor 180A. In some embodiments, touch operations acting on the same touch position but with different touch operation intensities can correspond to different operation instructions. For example: when a touch operation with a touch operation intensity less than the first pressure threshold acts on the short message application icon, an instruction to view the short message is executed. When a touch operation with a touch operation intensity greater than or equal to the first pressure threshold acts on the short message application icon, an instruction to create a new short message is executed.

It should be understood that the phone cards in the embodiments of the present application include but are not limited to SIM cards, eSIM cards, universal subscriber identity modules (USIM), universal integrated circuit cards (UICC), and the like.

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. The embodiment of the present application takes the Android system of the layered architecture as an example to exemplify the software structure of the electronic device 100.

FIG. 2 is a software structure block diagram of the electronic device 100 according to an embodiment of the present application.

The layered architecture divides the software into several layers, each with a clear role and division of labor. The layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into five layers, from top to bottom: application layer, application framework layer, Android runtime (ART) and native C/C++ library, hardware abstraction layer, and kernel layer.

The application layer can include a series of application packages.

As shown in FIG. 2 , the application package may include applications such as camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, short message, etc.

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

As shown in FIG. 2 , the application framework layer may include a window manager, a content provider, a view system, a resource manager, a notification manager, an activity manager, an input manager, and the like.

The window manager provides window management service (WMS). WMS can be used for window management, window animation management, surface management and as a transit station for the input system.

Content providers are used to store and retrieve data and make it accessible to applications. This data can include videos, images, audio, calls made and received, browsing history and bookmarks, phone books, etc. Content providers provide support for data access between applications.

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 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. It can be used to convey notification-type messages and can disappear automatically after a short stay without user interaction. For example, the notification manager is used to notify download completion, message reminders, etc. The notification manager can also be a notification that appears in the system top status bar in the form of a chart or scroll bar text, such as notifications of applications running in the background, or a notification that appears on the screen in the form of a dialog window. For example, a text message is displayed in the status bar, a prompt sound is emitted, an electronic device vibrates, an indicator light flashes, etc.

The activity manager can provide activity management service (AMS). AMS can be used to start, switch, and schedule system components (such as activities, services, content providers, broadcast receivers) as well as manage and schedule application processes.

The input manager can provide input management service (IMS), which can be used to manage the input of the system, such as touch screen input, key input, sensor input, etc. IMS takes events from input device nodes and distributes them to appropriate windows through interaction with WMS.

The Android runtime includes the core library and the Android runtime. The Android runtime is responsible for converting source code into bytecode, converting bytecode into machine code, and running machine code. In terms of compilation technology, the Android runtime supports ahead-of-time (AOT) compilation technology and just-in-time (JIT) compilation technology. AOT converts bytecode into machine code and stores it in the memory during application installation; JIT converts part of the bytecode into machine code in real time when the application is running.

The core library is mainly used to provide basic Java class library functions, such as basic data structures, mathematics, IO, tools, databases, networks, etc. The core library provides an API for users to develop Android applications.

The native C/C++ library can include multiple functional modules. For example: surface manager, media framework, libc, OpenGL ES, SQLite, Webkit, etc. Among them, the surface manager is used to manage the display subsystem and provide fusion of 2D and 3D layers for multiple applications. The media framework 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. libc provides a standard C function library. OpenGL ES provides drawing and operation of 2D graphics and 3D graphics in applications. SQLite provides a lightweight relational database for applications. Webkit provides support for browser kernels.

The modules in the application framework layer are written in Java, and the modules in the native C/C++ library are written in C/C++. The communication between the two can be achieved through the Java native interface (JNI).

The hardware abstraction layer runs in user space, encapsulates the kernel layer drivers, and provides a calling interface to the upper layer. It can include display modules, camera modules, audio modules, and Bluetooth modules.

The kernel layer is the layer between hardware and software. The kernel layer can include display drivers, camera drivers, audio drivers, Bluetooth drivers, and other sensor drivers. In addition to providing hardware drivers, the kernel layer also supports memory management, system process management, file system management, power management and other functions.

It should be understood that the technical solutions in the embodiments of the present application can be used in Android, IOS, Hongmeng and other systems.

Currently, users can use multiple devices or multiple screens in a coordinated manner to improve usage efficiency and user experience. For example, a user's laptop can be connected to an external display (or external screen), so that the user can use a set of input devices to control the laptop screen and the external display screen at the same time. Exemplarily, the input device may include a standard human interface device (HID), such as a keyboard, a mouse, a handle, a touchpad, etc.

However, in the existing solution, when the user's device is connected to an external display, the input device can only input to one place at the same time, and multiple users cannot operate different screens at the same time, which affects the efficiency of simultaneous use by multiple users.

Based on this, an embodiment of the present application proposes a display method and an electronic device, which can be applied to scenarios where the electronic device is used with an external display, or scenarios where multiple electronic devices are used in coordination, providing a solution for scenarios where multiple users use the device simultaneously.

Several exemplary usage scenarios provided by the embodiments of the present application are introduced below in conjunction with the accompanying drawings.

Figure 3 is a set of graphical user interfaces (GUI) provided in an embodiment of the present application.

As shown in Figure 3, the laptop is connected to an external monitor, and the laptop displays a memo application. At the same time, the game application running on the laptop can be displayed on the external monitor. That is, multiple display screens are controlled by one electronic device. The laptop can be connected to an external mouse, and the monitor can be connected to an external game controller. Furthermore, user 1 can operate the memo application through the keyboard and mouse of the laptop, and user 2 can control the game application displayed on the monitor through the game controller. Two users can operate at the same time without interfering with each other. It can be understood that the laptop can also be connected to two or more external monitors for more users to operate at the same time.

Exemplarily, the laptop computer and the display may be connected via a wired connection or a wireless connection. The input device and the laptop computer (or display) may also be connected via a wired connection or a wireless connection. Among them, the wireless connection may be a short-distance connection such as a high-fidelity wireless communication (Wi-Fi) connection, a Bluetooth connection, an infrared connection, an NFC connection, a ZigBee connection, etc. In addition, the wireless connection may also be a long-distance connection, and the long-distance connection includes but is not limited to mobile networks that support 2G, 3G, 4G, 5G and subsequent standard protocols. For example, multiple electronic devices can log in to the same user account (such as a Huawei account) and then connect remotely through a server. Exemplarily, multiple electronic devices may be connected through a hyperterminal (for example: An electronic device connected to a hyperterminal consisting of multiple devices.

FIG. 4A shows another set of GUIs provided by an embodiment of the present application.

As shown in Figure 4A, the laptop and tablet can be in collaborative mode, and the laptop and tablet run their own systems respectively, that is, the systems of the two devices control their own screens respectively. Exemplarily, the laptop and tablet can be connected by wire or wirelessly, and the input device and the laptop (or tablet) can also be connected by wire or wirelessly. The system of the laptop runs a memo application, the system of the tablet runs a chat application, and the external mouse of the laptop can be transferred to the tablet. If the user chooses to use the external mouse of the laptop to control the tablet, when user 1 uses the external mouse of the laptop to control the tablet, user 2 can use the keyboard of the laptop to input operations on the memo application at the same time, and the two users can operate at the same time without interfering with each other. It can be understood that Figure 4 takes the collaboration of two devices with independent systems as an example, and the present application does not limit the number of devices in collaborative mode.

FIG. 4B shows another set of GUIs provided by an embodiment of the present application.

As shown in FIG4B , the laptop computer and the tablet computer can be in a collaborative mode, and the laptop computer and the tablet computer respectively run their own systems. In addition, the tablet computer can be connected to an external display. The display can also be connected via a wired connection or a wireless connection, and the input device and the laptop, tablet, or external display can also be connected via a wired connection or a wireless connection. The laptop system runs a memo application, and the tablet system runs a chat application. At the same time, the game application run by the tablet can be displayed on the external display. In this scenario, if the user chooses to use the external mouse of the laptop to control the tablet, when user 1 uses the external mouse of the laptop to control the tablet, user 2 can use the keyboard of the laptop to input operations on the memo application at the same time. At the same time, user 3 can control the game application displayed on the external display through the game controller. The three users can operate at the same time without interfering with each other. It can be understood that in this scenario, the laptop and tablet run independent systems, and the laptop and tablet can both be connected to one or more external displays. This application does not limit this.

In some embodiments, the user can associate the input device with the corresponding device through the interactive interface. For example, in the embodiment shown in FIG3, when the user connects an external mouse to a laptop computer, the user can select the external mouse to control the laptop computer or the display through the configuration interface. Similarly, when the user connects a game controller to the laptop computer or the display, the user can also select the game controller to control the laptop computer or the display through the configuration interface. For another example, in the embodiment shown in FIG4A, when the user connects an external mouse to a laptop computer, the user can select the external mouse to control the laptop computer or the tablet through the configuration interface.

In other embodiments, the device corresponding to the input device can be associated with the device according to the scene. For example, in the embodiment shown in FIG3, when the user connects the game controller to the laptop or the display screen, since the interface displayed on the display screen at this time is the game application interface, the laptop can associate the game controller with the display by default.

Through the method provided in the embodiment of the present application, the input device can be associated with the device or screen it needs to control. Furthermore, multiple users can manipulate multiple devices or screens separately without interfering with each other. The method provided in the embodiment of the present application can be applied to scenarios where one device controls multiple screens, such as a scenario where a device is connected to an external display (as shown in Figure 3), a scenario where a system controls multiple display screens of a vehicle computer, etc. The method provided in the embodiment of the present application can also be applied to scenarios where multiple devices control multiple screens separately, such as scenarios where multiple devices work together (as shown in Figure 4A). The method provided in the embodiment of the present application can also be applied to scenarios where multiple devices control their respective screens separately, and at least one device is connected to an external display (as shown in Figure 4B), and this application does not limit this.

The above introduces two groups of GUIs in the embodiment of the present application in combination with Figures 3, 4A and 4B. The following introduces the implementation process of the technical solution in the embodiment of the present application in combination with the accompanying drawings.

FIG5 shows a schematic diagram of the interaction between modules of an electronic device in a scenario where an electronic device controls multiple screens. For example, FIG3 shows a scenario where a device controls multiple screens. The hardware structure and software structure of the electronic device can refer to the relevant description of the electronic device 100 in FIG1 and FIG2.

In some embodiments, as shown in FIG5 , the electronic device may include a multi-device input management module, an input subsystem, a screen management subsystem, and a screen display subsystem. Among them, the multi-device input management module can be used to manage the correspondence between input devices and screens, manage cursors on different screens, etc. The input subsystem can be used to manage input devices and process input events. The screen management subsystem can be used to handle the display screen. The graphics display subsystem can be responsible for presenting the drawn content on the screen. As shown in FIG5 , the method may include but is not limited to the following steps:

S501: The multi-device input management module obtains screen information from the screen management subsystem.

The screen information may include information about all screens in the current system. Usually, each screen has a different screen ID, and the screen ID is specified to determine which screen to display on, thus achieving multi-screen display.

Exemplarily, the screen information may include screen identifiers of all screens in the current system, and the multi-device input management module may obtain screen identifiers corresponding to all screens in the current system from the screen management subsystem. Optionally, the screen management subsystem may monitor screen changes in real time or at intervals, such as adding a new screen, removing the current screen, etc. When the screen changes, the multi-device input management module may obtain updated screen information from the screen management subsystem.

As another example, the screen information may also include configuration information of all screens in the current system, such as size, resolution, etc. Optionally, when the configuration (such as size, resolution) of the current screen changes, the multi-device input management module may also obtain updated screen information from the screen management subsystem.

S502: The multi-device input management module obtains input device information from the input subsystem.

Among them, the input device information may include information of all input devices in the current system. Exemplarily, the input device information may include identification, type information, etc. of all input devices in the current system. The multi-device input management module may classify and manage input devices according to the type of input device (e.g., mouse, keyboard, etc.). Optionally, the input subsystem may monitor changes in input devices in real time or at intervals, such as adding new input devices, removing current input devices, etc. When the input device changes, the multi-device input management module may obtain updated input device information from the input subsystem.

For example, the input device information may also include configuration information of all input devices in the current system, such as whether the input device is Support cursor operation, etc. Optionally, when the configuration of the input device changes, the multi-device input management module can also obtain updated input device information from the input subsystem.

It can be understood that step S501 and step S502 can be executed simultaneously or one after another, and the present application does not limit the execution order of step S501 and step S502.

S503: The multi-device input management module determines the association relationship between the screen and the input device.

In one implementation, the user can manually configure the association between the screen and the input device through the configuration interface, and then the multi-device input management module can obtain the association between the screen and the input device according to the user's settings. In another implementation, the system can automatically determine the association between the screen and the input device according to the scene, user habits, etc., and then the multi-device input management module can determine the association between the screen and the input device. This application does not limit the process and method of associating the screen and the input device.

Optionally, the user can configure the cursor styles of different input devices or different screens through the configuration interface, and then the multi-device input management module can obtain the cursor styles of different input devices or different screens according to the user's settings. The cursor style may include the shape and color of the cursor display. In this way, the user can distinguish different screens through different cursor styles, thereby improving the efficiency of multi-user use.

S504: The input subsystem obtains the association relationship between the screen and the input device from the multi-device input management module.

Optionally, the input subsystem may also obtain cursor styles of different input devices or different screens from the multi-device input management module.

S505: When the input device has a cursor attribute and the cursor does not exist on the screen associated with the input device, the input subsystem creates a cursor on the screen associated with the input device.

The input device being a cursor attribute can be understood as the input device supporting cursor operations. Exemplarily, the input subsystem can determine whether the input device supports cursor operations based on the characteristics of the input device. For example, when the input device has the INPUT_DEVICE_CLASS_CURSOR characteristic, it can be considered that the input device supports cursor operations.

It can be understood that, since only one cursor needs to be displayed on each screen, when the screen associated with the input device originally has a cursor, the input subsystem may not need to create a cursor, and when the screen associated with the input device originally does not have a cursor, the input subsystem may create a cursor on the screen associated with the input device. In this way, there can be at most one cursor on each screen to avoid interfering with user operations.

S506: The input subsystem distributes the event to the graphic display subsystem.

S507: The graphic display subsystem displays a cursor on the screen corresponding to the input device.

Optionally, the graphic display subsystem may display the cursor in a corresponding cursor style on a screen corresponding to the input device according to the cursor style corresponding to the different input devices or different screens.

Through the above steps, a corresponding relationship between the input device and the screen can be established. Further, the method may also include:

S508: The input subsystem detects a first input event and determines the screen on which the first input event acts.

Exemplarily, when a user operates a first input device, the input subsystem may detect a first input event corresponding to the first input device.

In one possible implementation, in step S504, the input subsystem can obtain the association relationship between the screen and the input device from the multi-device input management module. Then, in step S508, the input subsystem can determine the screen on which the first input event acts based on the association relationship between the screen and the input device and the first input device corresponding to the first input event.

In another possible implementation, after the input subsystem detects the first input event, the first input event can be sent to the multi-device input management module. The multi-device input management module can determine the screen affected by the first input event based on the association relationship between the screen and the input device, and the first input device corresponding to the first input event. Furthermore, the multi-device input management module can send the screen affected by the first input event to the input subsystem, so that the input subsystem can obtain the screen affected by the first input event. Optionally, in this implementation, in step S504, the input subsystem may not need to obtain the association relationship between the screen and the input device from the multi-device input management module.

S509: The input subsystem distributes the input event to the graphic display subsystem.

S510: The graphic display subsystem displays a cursor on a screen corresponding to the input device.

In some other embodiments, the electronic device may include an input subsystem, a screen management subsystem, and a screen display subsystem. The operation of the multi-device input management module shown in FIG5 may be completed by the input subsystem. For example, the multi-device input management module may be a module in the input subsystem. Exemplarily, the input subsystem may obtain all screen information in the current system from the screen management subsystem. In addition, The input subsystem can determine the association between the screen and the input device. When the input subsystem detects a first input event, the input subsystem can determine the screen on which the first input event acts based on the association between the screen and the input device it obtains, and distribute the input event to the graphics display subsystem.

FIG6 shows a schematic flow chart of a display method provided in an embodiment of the present application, which can be executed by a first electronic device, and the first electronic device can be the electronic device shown in FIG5 . The method includes:
