[0078] Figure 14 This is a block diagram of an electronic device according to an exemplary embodiment. Detailed Implementation

[0079] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0080] In related technologies, when one electronic device projects its screen onto another, all applications on the first device are projected onto the second. For example, the entire screen of a mobile phone can be directly mirrored onto a vehicle terminal. In this way, users can directly operate any application on their mobile phone on the vehicle terminal. However, the security and privacy of such projection are poor.

[0081] The screen casting method provided in this embodiment displays allowed applications on the screen casting interface of a first device. Users can select the target application to be cast from the allowed applications to display the target application's screen casting screen on the screen casting interface. This improves security and privacy while enabling application screen casting.

[0082] The screen projection method provided in this disclosure can be applied to screen projection display between any devices.

[0083] For example, it can be used for screen mirroring between a mobile phone and a vehicle infotainment system. For instance, a user can mirror an application from their mobile phone to the vehicle's infotainment system while driving, making it easier for them to view content on their phone. However, for some more private applications, such as payment applications or instant messaging applications, mirroring to the vehicle's infotainment system could potentially be seen by other passengers. Therefore, to protect user privacy and improve the privacy and security of screen mirroring, the screen mirroring method provided in this disclosure uses a privacy screen mirroring mode, where applications not being run by the user are not displayed on the vehicle's infotainment system.

[0084] For example, it can be used for screen mirroring between mobile phones and computers. Of course, it can also be used for screen mirroring between other devices, and this disclosure does not limit this application.

[0085] The method provided in this embodiment is executed by a first device and a second device, wherein the first device is a projection source and the second device is a projection device. For example, the first device can be a mobile phone, tablet computer, laptop computer, smart home device, wearable device, etc., and the second device can be a mobile phone, tablet computer, laptop computer, smart home device, vehicle terminal, etc.

[0086] Figure 1 This is a flowchart illustrating a screen mirroring method according to an exemplary embodiment, executed by a first device. See [link to flowchart]. Figure 1 The method includes the following steps:

[0087] Step S101: Display at least one first application in the screen mirroring interface of the first device; wherein the first application is an application on the second device that is allowed to be mirrored.

[0088] In this embodiment, a first application can be displayed on the screen mirroring interface, while a second application is not. The first application is any application on the second device that is allowed to be mirrored, and the second application is any application on the second device that is not allowed to be mirrored. Both the first and second applications can be third-party applications or system applications. For example, the first application could be a video application, music application, or game application on the second device, while the second application could be an instant messaging application, payment application, or other application involving user privacy. Which applications on the second device are designated as the first application and which as the second application can be configured by the user according to their needs.

[0089] The screen mirroring interface is the interface displayed on the physical screen of the first device. The screen mirroring interface displays the content displayed on the virtual screen of the second device. The first device displays the content mirrored by the second device in the screen mirroring interface.

[0090] The first device and the second device can be interconnected through USB (Universal Serial Bus), Bluetooth, local area network, P2P (peer-to-peer) and other methods. This embodiment does not limit the interconnection method of the first device and the second device.

[0091] Step S102: Select a target application from at least one first application; wherein the target application is the application to be projected.

[0092] After at least one primary application is displayed in the screen mirroring interface, when a user wants to mirror a specific primary application from the at least one primary application, they can select the target application from the at least one primary application. The target application is the application to be mirrored.

[0093] In some embodiments, in response to a selection operation of any one of the at least one first application, the selected first application is designated as the target application. The selection operation can be a click, double-click, swipe, or other operation.

[0094] Optionally, the first device sends a selection command to the second device, causing the second device to project the target application's screen onto the first device based on the selection command. The selection command instructs the user to perform the selection operation.

[0095] Step S103: Display the target application's screen in the screen mirroring interface; the target application's screen mirroring is the screen mirroring of the target application displayed on the virtual screen of the second device.

[0096] The screen to be projected from the target application can be the application interface of the target application or other screens of the target application.

[0097] The method provided in this embodiment displays allowed applications for screen mirroring on the screen mirroring interface of a first device. Users can select the target application to be mirrored from the allowed applications to display the mirrored screen of the target application on the screen mirroring interface. This improves the security and privacy of screen mirroring while realizing application screen mirroring.

[0098] Figure 2 This is a flowchart illustrating a screen mirroring method according to an exemplary embodiment, executed by a first device. See [link to flowchart]. Figure 2 The method includes the following steps:

[0099] Step S201: Display the projection interface on the physical screen of the first device in a preset display state.

[0100] The preset display states include a floating capsule display, a small window display, or a full-screen display. Users can set the preset display state according to their needs. Taking screen mirroring between a mobile phone and a car infotainment system as an example, if a user needs to view the navigation route provided by the car infotainment system, the mirrored interface can be displayed in the floating capsule state to avoid obscuring the navigation route provided by the car infotainment system. If a user needs to view the navigation route provided by the navigation application mirrored from their mobile phone, the mirrored screen can be displayed in either a small window or full-screen state for convenient viewing of the navigation route provided by the mobile phone.

[0101] See one example. Figure 3 The diagram shown is a schematic of the screen mirroring interface. Figure 3 Figure A shows the projection interface displayed on the physical screen in the floating capsule display state (the gray window in the figure). Figure 3 Figure B shows the projection interface displayed on the physical screen in the small window display mode. Figure 3 Figure C shows the projection interface displayed on the physical screen in full-screen mode.

[0102] Compared with the screen-sharing interface that dominates the display in related technologies, in this embodiment, the user can freely set the display state, which enriches the display state of the screen-sharing interface and improves flexibility. The user can set the display state according to the display needs.

[0103] It should be noted that the display state of the screen mirroring interface can be switched during the mirroring process. For example, the screen mirroring interface can be displayed in a small window first, and then switched to full-screen display.

[0104] Step S202: In response to the first activation operation, enable the privacy screen mirroring mode.

[0105] The first activation operation involves enabling the privacy casting control in the casting interface. Privacy casting mode means that casting to the first application is allowed on the first device, but casting to a second application is not permitted on the second device. In other words, the privacy casting control is displayed in the casting interface. When a user wants to enable privacy casting mode, they can perform the first activation operation on the privacy casting control, and the first device responds to this operation by enabling privacy casting mode.

[0106] In some embodiments, since the content displayed in the projection interface is obtained by projection from the second device, after the user performs an operation in the projection interface, it is necessary to send a corresponding instruction to the second device so that the second device can control the corresponding content on the virtual screen to perform the operation. After the second device completes the corresponding operation, it projects the content back to the first device so that the first device displays the latest content. Regarding the activation process of the privacy projection mode, the first device responds to the first activation operation by sending a first activation instruction to the second device, so that the second device activates the privacy projection mode based on the first activation instruction, and then the first device activates the privacy projection mode. The first activation instruction is used to indicate the first activation operation.

[0107] It should be noted that step S202 is described using the example of a user operating on a first device to enable the privacy screen casting mode. In another embodiment, the user can operate on a second device to enable the privacy screen casting mode. In some embodiments, in response to the second enabling operation, the second device sends a second enabling command to the first device. Upon receiving the second enabling command from the second device, the first device enables its privacy screen casting mode based on the second enabling command. The second enabling command is used to instruct the second enabling operation, which is an operation to enable the privacy screen casting control on the second device.

[0108] It's worth noting that enabling the privacy casting mode is optional, and users can disable it if they no longer need it. With privacy casting mode disabled, it doesn't matter whether the application is the first or second application; either device can cast the first application to the first device, and vice versa. The first device can then display either application in the casting interface. Users can choose whether to enable privacy casting mode based on their needs, increasing flexibility and freedom during casting.

[0109] Step S203: Display at least one first application in the screen mirroring interface of the first device.

[0110] In some embodiments, a target application list is displayed in the screen mirroring interface; the target application list includes at least one first application that is allowed to be screen mirrored, but does not include a second application that is not allowed to be screen mirrored.

[0111] Optionally, the target application list includes the application icon and application identifier of the first application. See, in one example... Figure 4 The diagram shown illustrates the screen mirroring interface, where all applications displayed are the first application.

[0112] In some embodiments, a list of target applications is displayed in the screen mirroring interface based on a fake Launcher.

[0113] Step S204: Select the target application from at least one first application.

[0114] Step S205: Display the screen projection screen of the target application in the projection interface.

[0115] Taking the screen mirroring screen as the target application's interface as an example, see [example example]. Figure 5 The diagram shown illustrates the screen mirroring interface, which displays the application interface of the target application.

[0116] Step S206: In response to the control operation on the target application, a control command is sent to the second device so that the second device controls the target application on the virtual screen based on the control command.

[0117] The control commands are used to instruct control operations on the target application. For example, when displaying a list of target applications in the projection interface, the control operation can be to open the target application; when displaying the application interface of the target application in the projection interface, the control operation can be to operate on the various controls in the application interface. Of course, the control operation can also be other operations, and this embodiment of the disclosure does not limit the control operation.

[0118] In some embodiments, the control instructions include location information that characterizes the position of the control operation relative to the physical screen of the target device.

[0119] In addition, regarding the screen casting process in the above embodiments, in some embodiments, the second device encodes the screen casting image on the virtual screen to obtain encoded display data, and then sends the display data to the first device. The second device decodes the display data to obtain the corresponding screen casting image, which is then displayed in the screen casting interface. The screen casting image on the virtual screen refers to the content displayed in the screen casting interface of the second device; for example, the screen casting image might be a display of a list of target applications, or a display of the application interface of the target application. Optionally, when sending the display data, the second device can encapsulate the display data and send the encapsulated display data. After receiving the encapsulated display data, the first device first decapsulates the encapsulated display data to obtain the display data. This disclosure does not limit the process of sending the screen casting image during screen casting.

[0120] The method provided in this embodiment displays allowed applications for screen mirroring on the screen mirroring interface of a first device. Users can select the target application to be mirrored from the allowed applications to display the mirrored screen of the target application on the screen mirroring interface. This improves the security and privacy of screen mirroring while realizing application screen mirroring.

[0121] Furthermore, the privacy-focused screen mirroring mode provided in this embodiment is applicable to various display states of the screen mirroring interface, offering high flexibility and enhancing user freedom of operation.

[0122] In some embodiments, users can configure which applications are designated as the first application and which are designated as the second application on a first device. This will be explained below. Figure 6 The illustrated example explains the application setup process.

[0123] Figure 6 This is a flowchart illustrating an application setup process according to an exemplary embodiment, performed by a first device. See also... Figure 6 The method includes the following steps:

[0124] Step S601: Display the application management page in the screen mirroring interface.

[0125] The application management page displays the applications on the second device, and the application management page is displayed on the virtual screen of the second device. Optionally, the application management page displays the application icon and application identifier, or displays the application identifier.

[0126] In some embodiments, the screen mirroring interface displays an entry point to the application management page, and in response to a trigger operation on the entry point, the application management page is displayed in the screen mirroring interface.

[0127] In step S602, in response to the setting operation of the application in the application management page, the application is set as the first application or the second application.

[0128] The application refers to any application displayed on the application management page. Settings actions can include moving, deleting, adding, or other actions related to the application.

[0129] In some embodiments, in response to a setting operation on an application in an application management page, the first device sends a setting instruction to the second device, causing the second device to set the application as either a first application or a second application based on the setting instruction, and then the first device sets the application as either a first application or a second application. The setting instruction is used to instruct the setting operation on the application.

[0130] In some embodiments, in response to a first setting operation on an application, the application is set as a first application, wherein the first setting operation is an operation of adding the application to a first application list in the application management page, the first application list including applications that are allowed to be cast to the screen; or, in response to a second setting operation on an application, the application is set as a second application, wherein the second setting operation is an operation of adding the application to a second application list in the application management page, the second application list including applications that are not allowed to be cast to the screen.

[0131] Optionally, the application management page includes an "Unset" list, a "First Application" list, and a "Second Application" list. When an application is in the "Unset" list, to set it as the first application, move the application from the "Unset" list to the "First Application" list; similarly, to set it as the second application, move it from the "Unset" list to the "Second Application" list. If an application is in the "First Application" list and you want to set it as the second application, first delete the application; the deleted application will then be in the "Unset" list, and you can then move it from the "Unset" list to the "Second Application" list. Similarly, if an application is in the "Second Application" list and you want to set it as the first application, first delete the application; the deleted application will then be in the "Unset" list, and you can then move it from the "Unset" list to the "First Application" list.

[0132] Optionally, the application management page includes a first application list and a second application list. If an application is in the first application list and you want to set it as the second application, you must first delete the application; the deleted application will then be in the second application list. If an application is in the second application list and you want to set it as the first application, you must first add the application; the added application will then be in the first application list. See the example below. Figure 7 The diagram shown is an illustration of the application management page. Figure 7 Taking an application management page that displays 7 apps as an example, the first application list is... Figure 7 The "Displayed Applications" list contains APP1-APP6, each with a corresponding delete control. Users can delete an app by clicking the corresponding delete control when they want to prevent screen mirroring. The second application list is... Figure 7 In the "Don't show apps" list, there are APP7. Each app has a corresponding add control. When a user wants to set an app as an application that can be cast to the screen, they can click the corresponding add control.

[0133] Of course, the application management page can also take other forms. In this embodiment of the disclosure, there are no restrictions on the specific display form of the application in the application management page.

[0134] In some embodiments, in response to a first setting operation, the first device sends a first setting instruction to the second device, causing the second device to set the application as a first application based on the first setting instruction, and then the first device sets the application as the first application, wherein the first setting instruction is used to instruct the first setting operation. Alternatively, in response to a second setting operation, the first device sends a second setting instruction to the second device, causing the second device to set the application as a second application based on the second setting instruction, and then the first device sets the application as the second application, wherein the second setting instruction is used to instruct the second setting operation.

[0135] In this embodiment of the disclosure, the user can set which applications are the first application and which are the second application according to actual needs, thereby controlling which applications are allowed to be cast and which are not, and improving the security and privacy of casting.

[0136] The above Figure 1 , Figure 2 and Figure 6 The illustrated embodiment describes the screen projection method from the perspective of a first device. The following will explain... Figure 8 The illustrated embodiment explains the screen projection method from the perspective of a second device.

[0137] Figure 8 This is a flowchart illustrating a screen mirroring method according to an exemplary embodiment, performed by a second device. See [link to flowchart]. Figure 8 The method includes the following steps:

[0138] Step S801: Cast at least one first application from the second device to the first device; wherein the first application is an application in the second device that is allowed to be cast.

[0139] In some embodiments, the list of target applications displayed on a virtual screen is projected onto a first device so that the first device displays the list of target applications in the projection interface.

[0140] Step S802: When at least one target application in the first application is the application to be cast, the casting screen of the target application displayed on the virtual screen of the second device is cast to the first device, so that the casting screen is displayed on the first device in the casting interface.
