Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a selection method and apparatus for a multi-user system. Background Technology

[0002] Currently, many electronic devices support multi-user functionality. Multi-user functionality allows different users to set different desktops, applications, etc., for the same electronic device, making it easier for different users to personalize their use of the device.

[0003] Existing multi-user functions typically display the information of the currently logged-in user and other available users on the lock screen during the selection process. Users need to manually configure various desktop and theme information, which is cumbersome. In addition, if a non-owner uses the electronic device, it is relatively easy to obtain the owner's personal information, resulting in poor security. Summary of the Invention

[0004] The purpose of this application is to provide a method and apparatus for selecting a multi-user system, which can solve the problems of cumbersome operation and poor security when entering a multi-user system.

[0005] In a first aspect, embodiments of this application provide a selection method for a multi-user system, applied to an electronic device having at least two screens, the method comprising:

[0006] When the first screen of the electronic device is locked, the second screen of the electronic device displays the first information of multiple users pre-set by the user.

[0007] Receive the first input to the first information;

[0008] In response to the first input, the system desktop of the first user corresponding to the first information is displayed, wherein the first information includes at least image information, and the first information is different for different users.

[0009] Secondly, embodiments of this application provide a selection device for a multi-user system, applied to an electronic device having at least two screens, the device comprising:

[0010] The first display module is used to display first information of multiple users preset by the user on the second screen of the electronic device when the first screen of the electronic device is in a locked state.

[0011] The first input module is used to receive a first input to the first information;

[0012] The second display module is used to respond to the first input and display the system desktop of the first user corresponding to the first information, wherein the first information includes at least image information, and the first information is different for different users.

[0026] The selection method and apparatus for a multi-user system provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0027] Figure 1 A flowchart illustrating the selection method for a multi-user system provided in this application embodiment is shown below. Figure 1 This application describes a method for selecting users in a multi-user system, as provided in embodiments of this application. Figure 1 As shown, the method is applied to an electronic device having at least two screens, and the method includes steps 101, 102 and 103.

[0028] Optionally, the electronic device can be implemented in various forms. For example, the electronic device described in the embodiments of this application may include mobile terminals such as mobile phones, smartphones, laptops, digital broadcast receivers, PDAs (personal digital assistants), PADs (tablet computers), PMPs (portable multimedia players), navigation devices, smart bracelets, smartwatches, digital cameras, etc., as well as fixed terminals such as desktop computers, televisions, etc. Hereinafter, it is assumed that the electronic device is a mobile terminal. However, those skilled in the art will understand that the construction according to the embodiments of this application can also be applied to fixed-type terminals.

[0029] Step 101: With the first screen of the electronic device locked, display multiple user-preset first information items on the second screen of the electronic device. The first information items include at least image information, and the first information items differ for each user.

[0030] Optionally, the electronic device may include at least two screens.

[0031] Optionally, the screen of the electronic device may include a non-foldable main screen and at least one secondary screen.

[0032] Optionally, the screen of the electronic device may include a foldable main screen and at least one secondary screen. The foldable main screen may include at least two screens. The shape of the secondary screen can be arbitrary. The folding direction and angle of the foldable main screen are not limited.

[0033] Figure 2 The left and right parts respectively show the cases where the sub-screen 201 of the electronic device is a circular screen and a rectangular screen. Figure 2 The foldable main screen consists of two screens, which can be folded vertically. The angle between the two folded screens is θ. When θ∈[0°, 180°], it indicates a forward fold, and when θ∈(180°, 360°), it indicates a reverse fold. Figure 2 The left and right parts show the case where the included angle θ of the two screens is 0° after they are folded.

[0034] Optionally, the electronic device supports a multi-user mode.

[0035] Multi-user mode is a mode that utilizes multi-user functionality. In multi-user mode, different users can set different desktops, applications, etc., for the same electronic device, allowing different users to personalize their use of the electronic device.

[0036] Optionally, users with permissions to use the electronic device, each user's initial information, and a system desktop for each user can be pre-configured. The number of such users can be multiple.

[0037] Understandably, one of the aforementioned users can be an administrator. The administrator is generally the device owner. The device owner refers to the person who owns the electronic device. The administrator is the default user with permission to use the electronic device.

[0038] The first information corresponding to a user may be information related to that user, but not the user's personal information. Optionally, the first information corresponding to a user may include image information. The image information corresponding to each user may include at least one first image. The first information corresponding to different users is different.

[0039] In addition to image information, the primary information corresponding to the user can also include other information, such as text information.

[0040] When the first screen of an electronic device is locked, the first information corresponding to each user can be displayed sequentially in a preset order on the second screen of the same electronic device. The first screen and the second screen are different screens.

[0041] Optionally, the first screen can be the main screen, and the second screen can be at least one secondary screen. Unless otherwise specified, the following embodiments are described using the example of the first screen as the main screen and the second screen as a secondary screen.

[0042] Optionally, the first information corresponding to each user can be displayed sequentially in a preset order, or the first information can be switched at preset time intervals, displaying the first information corresponding to one user at a time.

[0043] Optionally, in response to a first switching command input by the user, the first piece of information corresponding to a certain user can be switched to another piece of first information corresponding to that user.

[0044] Optionally, in response to a second switching command input by the user, the first piece of information corresponding to a certain user can be switched to displaying the first piece of information corresponding to another user.

[0045] Optionally, taking the secondary screen as an example, after the secondary screen is locked, it can display image information corresponding to multiple users set by the administrator after it is turned on. Specifically, this may include:

[0046] 1. If the administrator has not created multiple other users, then play all the first images set by the administrator in a loop;

[0047] 2. If the administrator creates multiple users, all the first images set by the administrator can still be displayed on the secondary screen, but the administrator can switch the first image played on the secondary screen using different operation commands.

[0048] Optionally, the administrator can switch the first image played on the secondary screen using different operation commands, including but not limited to the following methods:

[0049] a) By default, after displaying all the first images of a certain user, the system switches to display all the first images of the next user;

[0050] b) If all the first images of the current user have not been displayed, other first images of the current user can be switched by horizontally swiping the secondary screen.

[0051] c) Switch the display of the next user's first image by swiping the secondary screen vertically or touching the edge of the secondary screen clockwise / counterclockwise;

[0052] d) By using a certain operation command, such as double-clicking the secondary screen, thumbnails of all users are displayed. When the target user is selected, the secondary screen will display the first image of the target user.

[0053] Step 102: Receive the first input for the first information.

[0054] Optionally, it may receive a user's first input on the first information displayed on the second screen.

[0055] The first input can be implemented in various ways. The first input can be key input, voice input, action input, or gesture input, etc.

[0056] Optionally, the first input to the first information displayed on the second screen can be the first input to the first information currently displayed on the second screen, or it can be the first input to other first information.

[0057] Step 103: In response to the first input, display the system desktop of the first user corresponding to the first information.

[0058] Optionally, after receiving the first input, a response can be made to the first input to determine the first user based on a preset method for determining the first user. The first user can be at least one of the users authorized to use the electronic device.

[0059] Optionally, the user corresponding to the first information targeted by the first input can be identified as the first user.

[0060] Optionally, the first input may carry a password, and the user matching the password is identified as the first user. The password can be a character password, a voice password, or a biometric password such as a fingerprint.

[0061] Optionally, the user can be identified as the first user based on which user's first information is displayed on the first screen when the first input is made.

[0062] Once the first user is identified, the system desktop of the first user can be displayed on at least one screen of the electronic device to unlock it, allowing the first user to use the electronic device.

[0063] Optionally, if the second screen is a secondary screen, the system desktop of the first user can be displayed on the main screen of the electronic device.

[0064] This application embodiment does not display the information of the currently logged-in user, nor the information of other optional users. Instead, it displays the first information of each user's non-user information in turn. In response to the first input, it displays the system desktop for the first user. This makes the operation simpler and more convenient when entering a multi-user system. Furthermore, it does not obtain the information of other users during the entire process, which can improve security, reduce the probability that other users will notice that the electronic device is in multi-user mode, and improve the user experience.

[0065] Optionally, in response to the first input, displaying the system desktop of the first user corresponding to the first information includes: in response to the first input, displaying the system desktop of the first user in a preset manner. The preset manner of displaying the system desktop of the first user includes: maintaining the display of the system desktop of the first user when the screen displaying the system desktop switches from a locked state to a displayed state.

[0066] Optionally, after receiving the first input, the system can respond to the first input and display the first user's system desktop in a preset manner.

[0067] Optionally, the preset method can be related to the first input or not.

[0068] The preset method is unrelated to the first input, meaning that the preset method is the same regardless of the specific form of the first input; the preset method is unrelated to the first input, meaning that the preset method is the method corresponding to the first input, that is, different specific forms of the first input can correspond to different preset methods.

[0069] Optionally, after the first user's system desktop is displayed in a preset manner, after the screen displaying the first user's system desktop is locked, the electronic device receives an unlock command for the screen and switches the screen from the locked state to the displayed state, while still displaying the first user's system desktop.

[0070] This application embodiment displays the system desktop of the first user in a preset manner in response to the first input. When the screen displaying the system desktop of the first user switches from the locked screen state to the display state, the system desktop of the first user is kept displayed, which makes it easier to lock the electronic device used by the first user and makes the operation simpler and more convenient.

[0071] Optionally, in response to the first input, displaying the system desktop of the first user corresponding to the first information includes: in response to the first input, determining the first user from the first N target users displayed in the preset list; where N is the number of screens of the current electronic device and N is a positive integer greater than 1.

[0072] Optionally, the administrator can pre-select at least one target user, forming a preset list. The preset list is used to store information about the target users.

[0073] In response to the first input, the number N of screens on the current electronic device can be obtained first.

[0074] Optionally, if the electronic device does not include a foldable main screen, the number of screens in the current electronic device is the number of screens included in the electronic device.

[0075] Optionally, when the electronic device includes a foldable main screen, the number N of screens in the current electronic device can be obtained based on the folding state of the foldable main screen and the number of other screens.

[0076] Optionally, when the foldable main screen is in a fully unfolded state (i.e., forming a display surface), the number of screens of the current electronic device is the number of other screens plus 1; when the foldable main screen is in a fully folded state, the number of screens of the current electronic device is the number of other screens; when the foldable main screen is in a state that is neither fully unfolded nor fully folded, the number of screens of the current electronic device is the number of other screens plus the number of screens included in the foldable main screen.

[0077] Optionally, if the number M of target users displayed in the preset list is greater than or equal to N, the first N target users displayed in the preset list can be determined as the first user.

[0078] Optionally, a preset list can be used to display the target user.

[0079] Display the system desktops of N users on N screens; any two screens display different system desktops.

[0080] Optionally, on each of the N screens of the current electronic device, a system desktop of a first user is displayed, and the system desktops displayed on any two screens are system desktops of different first users.

[0081] Optionally, if the number M of target users displayed in the preset list is less than N, all users displayed in the preset list can be identified as first users; system desktops for the M first users can be displayed on the M screens of the electronic device; the system desktops displayed on any two of the M screens are system desktops for different first users.

[0082] Optionally, if the administrator has not created multiple users, regardless of which first message is displayed on the second screen, the user will be logged into the same user system and the same user desktop will be displayed.

[0083] Optionally, if the administrator creates multiple users, they will enter different user systems based on the content displayed on the second screen and the first input, and display the system desktop of each first user.

[0084] Optionally, based on the content displayed on the secondary screen and the first input, different user systems are accessed, and system desktops tailored to different first users are displayed. These desktops may include, but are not limited to, the following:

[0085] a) When a user's image is displayed on the secondary screen and the electronic device is not folded, the corresponding user will be launched directly without locking the user. "Without locking the user" means that when the screen is locked again, the system will switch to another user based on the user's image displayed on the secondary screen.

[0086] (b) When a user's image is displayed on the secondary screen and the electronic device is in a folded state (e.g., folded forward), the corresponding user is directly activated and locked. Locking the user means that even if another user's image is displayed on the secondary screen after the screen is locked again, the user will not switch upon triggering unlock. Once a user is locked, administrator verification is required to unlock it. The unlock command is associated with the command used to activate the user; for example, if the device was folded forward when the user was activated, the device needs to be folded backward to unlock.

[0087] Optionally, if an administrator has created multiple users and wants to access multiple users, they can retain the target user and then unlock the device via the first input, so that the system desktop for each user is displayed on different screens in the electronic device.

[0088] Specifically as follows:

[0089] a) When the electronic device is fully unfolded, if the first screen is a foldable screen, the first screen can be treated as a single screen, and the maximum number of users that can be received is 2. If the number of target users M>2, the first 2 users are activated, and the system desktop for these 2 users is displayed on the main screen and the secondary screen.

[0090] b) When the electronic device is in a folded state, the main screen is processed according to the number of screens after folding. If the number of screens after folding is K, the maximum number of users that the system can receive is (K+1). If the number of target users M>(K+1), the system desktop for the first (K+1) users is started and displayed on the main screen and secondary screen for these (K+1) users.

[0091] In this embodiment, the first user is determined by the first N target users displayed in the preset list, where N is the number of screens of the electronic device currently used to display the interface. The system desktop for the N first users is displayed on the N screens, and the system desktop displayed on any two screens is different. This reduces the number of operation steps for the user and makes it easier for multiple users to use the electronic device at the same time.

[0092] Optionally, before displaying the system desktop of the first user corresponding to the first information in response to the first input, the method further includes: receiving a second input from the user.

[0093] Optionally, a second input from the administrator can be accepted.

[0094] Secondary input can be implemented in various ways. Secondary input can be key input, voice input, gesture input, or other similar methods.

[0095] Optionally, the second input can be the input of the first information.

[0096] In response to the second input, a preset list is retrieved; the preset list displays at least two target users.

[0097] Optionally, after receiving the second input, the system can respond to the second input in a certain way, displaying information about all users who have been pre-configured by the administrator to have permission to use the electronic device, identifying target users among all the aforementioned users, and obtaining a preset list for displaying information about each target user. The number of target users is greater than or equal to two.

[0098] For example, an administrator can use a certain operation command to make the secondary screen display images of multiple users. For instance, after triggering the secondary screen to display thumbnails of all users, an administrator can use a long-press or other operation command to delete non-target users, retaining two or more target users. It is understood that in the above example, the second input includes both the certain operation command and the long-press or other operation command.

[0099] Based on the second user input, this application embodiment obtains and displays a preset list of at least two target users, which makes it easier to identify target users, display the target user's system desktop more conveniently, and simplify the operation of entering a multi-user system.

[0100] Optionally, when the first screen of the electronic device is locked, before displaying the first information of multiple users pre-set by the user on the second screen of the electronic device, the method further includes receiving a third input.

[0101] Optionally, a second input from the administrator can be received. The administrator can then set the user's initial information based on the third input.

[0102] Third input can be implemented in various ways. Third input can be key input, voice input, action input, or gesture input, etc.

[0103] In response to the third input, determine the first information corresponding to at least one user.

[0104] Optionally, after receiving the third input, a response can be made to the third input, and based on the third input, first information corresponding to at least one user can be determined.

[0105] Optionally, administrators can create other users based on their needs for multiple users. If an administrator does not use the multi-user feature, they do not need to create any additional users; if an administrator wants to create other users, they can do so based on their own needs, such as creating "children," "friends," or other users.

[0106] Optionally, based on third input, the lock screen image can be set as the first piece of information corresponding to the user. If the administrator has not created any other users, the lock screen image is not associated with any user; if the administrator creates different other users, the administrator can set a lock screen image for each user based on the third input, and the same user can be associated with multiple lock screen images.

[0107] The process of adding a lock screen image based on third-party input can be as follows: Figure 3 As shown. Figure 3 As shown in the left half of the image, administrators can create other users by clicking the "Create User" button; and input a third input by dragging lock screen images (images 1 to 4) from the lock screen gallery, setting at least one lock screen image as the first information corresponding to a user. Figure 3 The right half of the image shows that the first information for the user "child" is image 1 and image 2, and the first information for the user "friend" is image 3 and image 4.

[0108] This application embodiment determines the first information corresponding to at least one user in response to a third input, which can reduce the user's operation steps and make it easier to set the user's first information. Thus, the information of the currently logged-in user and the information of other optional users are not displayed, thereby realizing multi-user functionality and improving security.

[0109] Optionally, when the first screen of the electronic device is locked, before displaying the first information of multiple users pre-set by the user on the second screen of the electronic device, the method further includes receiving a third input.

[0110] Optionally, a fourth input from the administrator can be accepted. Based on this fourth input, the administrator can configure public settings on the system desktop and allow other users to access certain applications.

[0111] The fourth input method can be implemented in various ways. It can be key input, voice input, motion input, or gesture input, etc.

[0112] In response to the fourth input, the common settings on the system desktop are set to default values, and the icon of the first application is displayed on the system desktop; the first application is a preset application that the current user has permission to use.

[0113] Optionally, after receiving the fourth input, you can respond to the fourth input and, based on the fourth input, set public settings for the system desktop and allow other users to use the applications.

[0114] The system desktop's common settings can include desktop wallpaper, themes, and fonts.

[0115] Setting common system desktop settings to default values ​​means that all common system desktop settings for each user are set to their default values. This ensures that every user has the same initial system desktop when using an electronic device, eliminating the need for that user to configure their system desktop from scratch. Common settings such as desktop and theme remain consistent across different users, requiring no reconfiguration. If a user is dissatisfied with the initial system desktop, they can personalize it using their electronic device.

[0116] Optionally, based on the fourth input, a first application that can be allowed for each other user can be set, and the icon of the first application can be displayed on the system desktop.

[0117] It is understandable that, when any other user is the current user, the application that the other user is allowed to use is the application that the other user has permission to use, i.e., the first application.

[0118] By following the steps above, the same application can be set to be used by different users without having to reinstall the application. When different users use it, only the data portion is independent. For applications that a user does not have permission to use, no information about the application, including its icon and application name, will be displayed after the user logs in.

[0119] The process of setting the first application based on the fourth input can be as follows: Figure 4 As shown. Figure 4 As shown, the fourth input can include clicking the user's corresponding first control 401 and selecting an application from the application list. Clicking the user's corresponding first control 401 will navigate to the application list interface used to display the application list.

[0120] This application embodiment, in response to the fourth input, sets the common settings on the system desktop to the default value and displays the icon of the first application on the system desktop. This not only helps administrators reduce many steps in changing system settings, but also avoids the problem of wasted storage space caused by users installing the same application, thus bringing a better user experience.

[0121] The multi-user system selection method provided in this application can be executed by a multi-user system selection device. This application uses the example of a multi-user system selection device executing the multi-user system selection method to illustrate the multi-user system selection device provided in this application.

[0122] Figure 5 This is a schematic diagram of the structure of the selection device of the multi-user system provided in an embodiment of this application. Optionally, as... Figure 5 As shown, this device is applied to an electronic device having at least two screens. The device may include a first display module 501, a first input module 502, and a second display module 503, wherein:

[0123] The first display module 501 is used to display multiple user-related first information pre-set by the user on the second screen of the electronic device when the first screen of the electronic device is locked.

[0124] The first input module 502 is used to receive a first input of the first information;

[0125] The second display module 503 is used to respond to the first input and display the system desktop of the first user corresponding to the first information, wherein the first information includes at least image information, and the first information is different for different users.

[0126] Optionally, the first display module 501, the first input module 502, and the second display module 503 can be electrically connected.

[0127] When the first screen of the electronic device is locked, the first display module 501 can display the first information of each user in a preset order on the second screen of the electronic device.

[0128] The first input module 502 can receive a user's first input on the first information displayed on the second screen.

[0129] The second display module 503 can respond to the first input and determine the first user corresponding to the first information targeted by the first input based on a preset method for determining the first user. After determining the first user, the system desktop of the first user can be displayed on at least one screen of the electronic device to unlock it, so that the first user can use the electronic device.

[0130] Optionally, the second display module 503 may be specifically used to display the system desktop of the first user in a preset manner in response to the first input;

[0131] The preset method for displaying the first user's system desktop includes: maintaining the display of the first user's system desktop when the screen displaying the first user's system desktop switches from a locked state to a display state.

[0132] Optionally, the second display module 503 may include:

[0133] The first determining unit is configured to determine the first user from the first N target users displayed in the preset list in response to the first input; where N is the number of screens of the current electronic device and N is a positive integer greater than 1.

[0134] The first display unit is used to display the system desktops of N first users on N screens; any two screens among the N screens display different system desktops.

[0135] Optionally, the selection device for a multi-user system may further include:

[0136] The second input module is used to receive a second input from the user.
