Detailed Implementation

[0027] 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 this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0028] In related technologies, the task management interface only displays a preview interface for one fully displayed application. Users can only view and manage the application corresponding to the fully displayed preview interface. If a user wants to view and manage other running applications, they need to perform a swipe operation on the task management interface, which is inefficient and inconvenient. Therefore, this disclosure provides a method for displaying a task management interface, and an apparatus based on this method. In this disclosure, preview interfaces for multiple running applications are arranged in a grid pattern in the task management interface, with no overlap between the preview interfaces. Users can view preview interfaces for multiple applications simultaneously, and no other operations are required when managing the applications corresponding to the preview interfaces displayed in the task management interface, improving operational efficiency and convenience.

[0029] The method provided in this disclosure can be executed by a mobile terminal, such as a mobile phone, tablet computer, e-book reader, multimedia playback device, PDA (Personal Digital Assistant), wearable device, or other mobile terminal device.

[0030] Figure 1A This is a flowchart illustrating a method for displaying a task management interface according to an exemplary embodiment. The method is applied in a mobile terminal and may include the following steps: In step 101, a first trigger signal is received to trigger the display of the task management interface.

[0031] The task management interface is the display interface of the task manager. It typically shows previews of the applications currently running on the mobile device, allowing users to view and manage these applications. The first trigger signal is used to activate the task management interface, and this is usually triggered by the user.

[0032] In one possible implementation, the first trigger signal is a swipe operation signal with a swipe speed less than a preset speed. When a user performs a swipe operation on the current display interface of the mobile terminal, if the mobile terminal detects that the speed corresponding to the swipe operation signal triggered by the user is less than the preset speed, the mobile terminal receives the first trigger signal used to trigger the display of the task management interface. The speed corresponding to the swipe operation signal is the ratio between the trajectory length of the swipe operation signal and the duration of the swipe operation signal. The preset speed can be set according to actual needs, and this embodiment does not limit it. For example, the preset speed is 2 centimeters per second.

[0033] In another possible implementation, the first trigger signal is a swipe operation signal whose dwell time at the end position exceeds a preset duration. When a user performs a swipe operation on the current display interface of the mobile terminal, if the mobile terminal detects that the swipe operation signal triggered by the user has a dwell time at the end position of the swipe operation signal exceeding the preset duration, then the mobile terminal receives a first trigger signal for triggering the display of the task management interface. The preset duration can be set according to actual needs, and this embodiment does not limit it. For example, the preset duration is 2 seconds.

[0034] It should be noted that the above-mentioned first trigger signal is merely exemplary and illustrative, and can be preset according to actual needs. This disclosure does not limit this aspect.

[0035] In step 102, n applications running on the mobile terminal are obtained according to the first trigger signal, where n is an integer greater than 1.

[0036] Running applications include those running in the foreground and those running in the background of a mobile device. Applications running in the foreground are those whose user interface is directly displayed on the current screen of the mobile device, while applications running in the background are those whose user interface is not displayed on the current screen but are still running.

[0037] In step 103, for each application, the preview interface corresponding to the application is obtained.

[0038] The preview interface for an application can be a preview image of the application's current display interface, or a pre-set preview image related to the application.

[0039] When the preview interface corresponding to the application is a preview image of the application's current display interface, obtaining the preview interface corresponding to the application can include the following possible implementation methods.

[0040] In the first possible implementation, the current display interface of the application is scaled down from a first size to a second size to generate a preview interface corresponding to the application.

[0041] The first size is the size of the application's current display interface, which can be equal to or slightly smaller than the mobile terminal's screen size. The second size is the size of the application's corresponding preview interface. The second size is smaller than the first size. Optionally, after the mobile terminal obtains the application's current display interface, it needs to scale it down proportionally (including scaling down the entire current display interface and its individual elements, such as icons), to obtain the second-sized current display interface, which is the application's corresponding preview interface.

[0042] In the second possible implementation, a third-sized display area is captured from the application's current display interface; the third-sized display area is then shrunk to a fourth size to generate a preview interface for the application.

[0043] Unlike the first possible implementation, in the second possible implementation, the preview interface of the application is obtained based on a portion of the application's currently displayed interface. The third size is the size of the portion of the application's currently displayed interface. Optionally, the third size is half of the first size. The fourth size is the size of the preview interface of the application. Optionally, the fourth size is half of the second size. In this implementation, the mobile terminal first performs a cropping process on the application's currently displayed interface to obtain a portion of the application's currently displayed interface, and then proportionally scales down this portion of the application's currently displayed interface to obtain the preview interface of the application.

[0044] In the third possible implementation, the current display interface of the application is reduced from the first size to the second size; a fourth size display area is extracted from the reduced current display interface of the application to generate the corresponding preview interface of the application.

[0045] Unlike the first possible implementation, in the third possible implementation, the preview interface of the application is obtained based on a portion of the application's currently displayed interface. In this implementation, the mobile terminal first scales down the application's current displayed interface proportionally to obtain a scaled-down current displayed interface. Then, it crops this scaled-down current displayed interface to obtain the preview interface of the application. Here, the second size is the size of the scaled-down current displayed interface, and the fourth size is the size of the preview interface of the application. The fourth size is smaller than the second size.

[0046] When the preview interface corresponding to an application is a pre-defined preview image of an interface related to that application, the mobile terminal stores a preset correspondence between applications and preview interfaces. After the mobile terminal obtains the running application, it searches for the aforementioned preset correspondence to obtain the preview interface corresponding to that application.

[0047] In step 104, the task management interface is displayed. The task management interface includes preview interfaces for each of the n applications, and the preview interfaces for each of the n applications are arranged in a grid.

[0048] The preview interfaces for each of the n applications do not overlap in the task management interface. Additionally, the task management interface includes identifiers for these n applications, such as their icons and names.

[0049] Optionally, the task management interface is divided into m columns, with the application's preview interface arranged sequentially in each column, where m is an integer greater than 1. Optionally, m is 2. This arrangement can also be called a vertical waterfall layout. (Refer to the reference.) Figure 1B The diagram illustrates a task management interface 10 according to an exemplary embodiment. The task management interface 10 includes preview interfaces 11 for each of four applications.

[0050] Because the preview screens for individual applications are smaller than the task manager interface, the task manager can typically display previews for multiple applications directly. However, when a large number of applications are running, the task manager only displays previews for a subset; users can swipe to trigger the display of previews for the remaining applications.

[0051] Optionally, the task management interface also includes a preferred preview screen that is placed at the forefront of the task management interface. For example, the preferred preview screen is located in the upper left corner of the task management interface.

[0052] In the first example, the preferred preview screen is the preview screen for the application currently running in the foreground. In the second example, the preferred preview screen is the preview screen for the music application. In the third example, the preferred preview screen displays system function options. Since there are usually many system function options, the preferred preview screen only displays a portion of them. Therefore, an extended operation control can be set in the preferred preview screen. This extended operation control can be a small triangle; when the user triggers this extended operation control, the terminal displays all system function options.

[0053] Reference Figure 1C The diagram illustrates a preferred preview interface 12 as shown in an exemplary embodiment. This preferred preview interface 12 is the preview interface corresponding to a music application. (Refer to the reference...) Figure 1D The diagram illustrates a preferred preview interface 12 as shown in an exemplary embodiment. The preferred preview interface 12 includes system function options 121 and extended operation controls 122.

[0054] Optionally, before step 104, the mobile terminal may first determine the display position of the application's preview interface in the task management interface. The following embodiments illustrate three possible implementations for determining the display position.

[0055] In the first possible implementation, the mobile terminal determines the display position of the preview interface of each of the n applications in the task management interface based on the most recent foreground running time of each application.

[0056] The most recent foreground runtime of an application refers to the point in time when the time interval between the application's most recent foreground runtime and the current time is the smallest. Optionally, the smaller the time interval between the most recent foreground runtime and the current time, the more prominent the preview interface of the application will be in the task management interface; conversely, the larger the time interval, the more prominent the preview interface will be in the task management interface. In a specific example, the preview interface of an application that was running in the foreground before the mobile terminal displayed the task management interface will be at the very front of the task management interface.

[0057] In the second possible implementation, the mobile terminal determines the display position of the preview interface of each of the n applications in the task management interface based on the usage frequency of each application.

[0058] Application usage frequency refers to the frequency and number of times a user uses the application. Optionally, the higher the application usage frequency, the higher the display position of the application's preview interface in the task management interface; the lower the application usage frequency, the lower the display position of the application's preview interface in the task management interface.

[0059] In the third possible implementation, the mobile terminal determines the display position of the preview interface of each of the n applications in the task management interface based on the correlation between the n applications.

[0060] The correlation between two applications can be measured by the number of times they run simultaneously. The more times they run simultaneously, the higher the correlation; conversely, the fewer times they run simultaneously, the lower the correlation. Optionally, a higher correlation between two applications means their preview interfaces are closer together in the task management interface; a lower correlation means their preview interfaces are farther apart. In a specific example, the mobile terminal displays the preview interfaces of applications running in the foreground before the task management interface appears at the very top. Then, based on the correlation between other applications and the application corresponding to the foreground preview interface, the display positions of the preview interfaces of other applications in the task management interface are determined.

[0061] In summary, the method provided in this disclosure arranges the preview interfaces of multiple running applications in a grid pattern in the task management interface, with each preview interface not overlapping with the others. Users can view the preview interfaces of multiple applications simultaneously, and no other operations are required when managing the applications corresponding to the preview interfaces displayed in the task management interface, thus improving operational efficiency and convenience.

[0062] After the mobile terminal displays a preview of the running applications in the task management interface, the user can manage these applications within the task management interface, such as triggering the application to run in the foreground, triggering the application to stop running, etc. Based on... Figure 1A In an optional embodiment provided by the illustrated example, the method for displaying the task management interface may further include the following steps.

[0063] In step 201, a drag operation signal is received from the preview interface of the first application in the task management interface, where the starting position is located and the ending position is located in the preview interface of the second application in the task management interface.

[0064] In step 202, the first application and the second application are switched to run in the foreground according to the drag operation signal, and the display interfaces of the first application and the second application are displayed in a split screen.

[0065] When a user wants to run two applications simultaneously in the foreground, and these applications can be displayed in split-screen on the current display screen of the mobile terminal, the user can drag the preview screen of one application in the task management interface to the preview screen of another application. Then, the mobile terminal exits the task management interface based on the drag operation signal triggered by the user and displays the display screens of the two applications in split-screen on the current display screen.

[0066] Reference Figure 2 This illustration shows a split-screen display interface diagram according to an exemplary embodiment of the present disclosure. The task management interface 10 includes preview interfaces 11 corresponding to multiple running applications. When a user drags a preview interface 11 corresponding to one application to a preview interface 11 corresponding to another application, the terminal exits the task management interface 10 and displays the user interfaces 21 of the two applications in the current display interface 20.

[0067] Optionally, the method provided in this disclosure may further include the following steps.

[0068] When the mobile terminal receives a first operation signal corresponding to the preview interface of any application in the task management interface, it switches that application to run in the foreground based on the first operation signal. The first operation signal can be any one of the following: a click operation signal, a long press operation signal, or a swipe operation signal.

[0069] When the mobile terminal receives a second operation signal corresponding to the preview interface of any application in the task management interface, it stops running that application based on the second operation signal. The second operation signal can be any one of the following: a tap operation signal, a long press operation signal, or a swipe operation signal.

[0070] When the mobile terminal receives a third operation signal corresponding to the preview interface of any application in the task management interface, it displays a menu option box on top of the preview interface corresponding to that application, based on the third operation signal. The menu option box includes various menu options corresponding to that application. For example, the menu options may include any one of the following: a click operation signal, a long press operation signal, or a swipe operation signal.

[0071] Additionally, it should be noted that the first operation signal, the second operation signal, and the third operation signal are different.

[0072] In summary, the method provided in this disclosure can enable split-screen display on a mobile terminal based on dragging operation signals triggered by the user. Furthermore, it also provides functionality for managing various running applications.

[0073] Users can also manage all applications displayed in the task management interface's preview screens in a unified manner; for example, they can trigger all running applications to stop running. Based on... Figure 1A In an optional embodiment provided by the illustrated example, a delete operation control is also displayed on the upper layer of the task management interface. The method for displaying the task management interface may further include the following steps.

[0074] In step 301, a second trigger signal corresponding to the delete operation control is received.

[0075] In step 302, n applications are stopped from running according to the second trigger signal.

[0076] The delete control is used to stop all running applications, allowing users to manage all running applications in a unified manner. (Refer to the reference.) Figure 3A This illustration shows a schematic diagram of the interface where the deletion operation control is triggered, as shown in an exemplary embodiment of this disclosure. The task management interface 10 includes preview interfaces 11 for multiple applications. A deletion operation control 31 is displayed on the upper layer of the task management interface 10. After the user clicks the deletion operation control 31, all running applications on the terminal stop running, and the preview interfaces for all applications are cleared in the task management interface 10.

[0077] Furthermore, since stopping all running applications only requires the user to trigger the delete operation control once, compared to triggering the preview interface displayed in the task management interface to stop the corresponding application in related technologies, the embodiments of this disclosure can effectively improve the user's operating efficiency.

[0078] Users can also quickly open applications that are not running on their mobile devices without exiting the task management interface, and conveniently manage system function options. Based on... Figure 1A In an optional embodiment provided by the illustrated example, the method for displaying the task management interface may further include the following steps.

[0079] In step 303, when a first sliding operation signal corresponding to a preset area in the task management interface is received, the application list is displayed.

[0080] The preset area can be a blank area in the task management interface, that is, an area in the task management interface where the preview interface is not displayed. The preset area can be located around the perimeter of the task management interface, such as the top, bottom, left, or right side, etc., and this embodiment of the disclosure does not limit this.

[0081] The application list includes applications installed on the mobile terminal. The mobile application list may include identifiers of the applications installed on the mobile terminal. The application identifier is used to uniquely identify the application; the application identifier can be an icon, name, etc., and this disclosure does not limit this. Furthermore, due to the limited display area of ​​the mobile terminal, the mobile terminal only displays the identifiers of some applications. The user can use a swipe gesture to make the mobile terminal display the identifiers of other applications besides the aforementioned ones.

[0082] Additionally, after the application list is displayed, if the user performs a swipe operation signal in the opposite direction to the first swipe operation signal on the application list, the mobile terminal will redisplay the task management interface.

[0083] The above method allows users to quickly open other applications that are not running on the mobile device without exiting the task management interface.

[0084] In step 304, when a second sliding operation signal corresponding to a preset area in the task management interface is received, the system function interface is displayed.

[0085] The system function interface includes system function options. Additionally, after displaying the system function interface, if the user performs a swipe operation signal in the opposite direction to the second swipe operation signal, the mobile terminal will redisplay the task management interface. (Refer to the reference.) Figure 3B This illustration shows a schematic diagram of the display system function interface 32 as shown in an exemplary embodiment of the present disclosure. The task management interface 10 includes preview interfaces 11 corresponding to multiple applications. When the area of ​​the task management interface 10 that does not display a preview interface receives a sliding operation signal from the user from left to right, the terminal displays the system function interface 32. The system function interface 32 includes system function options 121 and extended operation controls 122.

[0086] It should be noted that the first and second sliding operation signals have different sliding directions. Furthermore, the sliding directions of the two sliding operation signals can be determined based on the actual position of the preset area in the task management interface.

[0087] For example, when the preset area is located at the top or bottom of the task management interface, the first swipe signal is from left to right, and the second swipe signal is from right to left; or, the first swipe signal is from right to left, and the second swipe signal is from left to right. As another example, when the preset area is located on the left or right side of the task management interface, the first swipe signal is from top to bottom, and the second swipe signal is from bottom to top; or, the first swipe signal is from bottom to top, and the second swipe signal is from top to bottom. By using these methods, the area available for user swipe operations on the task management interface can be increased, making it easier for users to operate.

[0088] In summary, the method provided by the embodiments of this disclosure extends the functionality of mobile terminals to simultaneously stop all running applications by providing a deletion operation control. In addition, users only need to trigger the above-mentioned deletion operation control once to stop all running applications, avoiding the situation where users need to trigger the preview interface of each running application to stop the application, thereby improving operational efficiency.

[0089] In addition, by displaying an application list or system function interface when the user performs a swipe operation on a preset area in the task management interface, users can quickly open other applications that are not running on the mobile terminal without exiting the task management interface; on the other hand, users can conveniently manage system function options without exiting the task management interface.
