In some embodiments, the system may include a Kernel (Kernel), a command parser (shell), a file system, and an application program. The kernel, shell, and file system together make up the basic operating system structure that allows users to manage files, run programs, and use the system. After power-on, the kernel is started, kernel space is activated, hardware is abstracted, hardware parameters are initialized, and virtual memory, a scheduler, signals and interprocess communication (IPC) are operated and maintained. And after the kernel is started, loading the Shell and the user application program. The application program is compiled into machine code after being started, and a process is formed.

Referring to fig. 4, in some embodiments, the system is divided into four layers, which are an Application (Applications) layer (abbreviated as "Application layer"), an Application Framework (Application Framework) layer (abbreviated as "Framework layer"), an Android runtime (Android runtime) and system library layer (abbreviated as "system runtime library layer"), and a kernel layer from top to bottom.

In some embodiments, at least one application program runs in the application program layer, and the application programs can be Window (Window) programs carried by an operating system, system setting programs, clock programs, camera applications and the like; or may be an application developed by a third party developer such as a hi program, a karaoke program, a magic mirror program, or the like. In specific implementation, the application packages in the application layer are not limited to the above examples, and may actually include other application packages, which is not limited in this embodiment of the present application.

The framework layer provides an Application Programming Interface (API) and a programming framework for the application program of the application layer. The application framework layer includes a number of predefined functions. The application framework layer acts as a processing center that decides to let the applications in the application layer act. The application program can access the resources in the system and obtain the services of the system in execution through the API interface.

As shown in fig. 4, in the embodiment of the present application, the application framework layer includes a manager (Managers), a Content Provider (Content Provider), and the like, where the manager includes at least one of the following modules: an activity manager (ActivityManager) is used to interact with all activities running in the system; the Location Manager (Location Manager) is used for providing the system service or application with the access of the system Location service; a Package Manager (Package Manager) for retrieving various information related to an application Package currently installed on the device; a notification manager (notifiationmanager) for controlling display and clearing of notification messages; a Window Manager (Window Manager) is used to manage the icons, windows, toolbars, wallpapers, and desktop components on a user interface.

In some embodiments, the activity manager is to: managing the life cycle of each application program and the general navigation backspacing function, such as controlling the exit of the application program (including switching the user interface currently displayed in the display window to the system desktop), opening, backing (including switching the user interface currently displayed in the display window to the previous user interface of the user interface currently displayed), and the like.

In some embodiments, the window manager is configured to manage all window processes, such as obtaining a display size, determining whether a status bar is available, locking a screen, intercepting a screen, controlling a display change (e.g., zooming out, dithering, distorting, etc.) and the like.

In some embodiments, the system runtime layer provides support for the upper layer, i.e., the framework layer, and when the framework layer is used, the android operating system runs the C/C + + library included in the system runtime layer to implement the functions to be implemented by the framework layer.

In some embodiments, the kernel layer is a layer between hardware and software. As shown in fig. 4, the core layer includes at least one of the following drivers: audio drive, display drive, bluetooth drive, camera drive, WIFI drive, USB drive, HDMI drive, sensor drive (such as fingerprint sensor, temperature sensor, touch sensor, pressure sensor, etc.), and so on.

In some embodiments, the kernel layer further comprises a power driver module for power management.

In some embodiments, software programs and/or modules corresponding to the software architecture of fig. 4 are stored in the first memory or the second memory shown in fig. 2 or 3.

In some embodiments, taking the magic mirror application (photographing application) as an example, when the remote control receiving device receives a remote control input operation, a corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the input operation into an original input event (including information such as a value of the input operation, a timestamp of the input operation, etc.). The raw input events are stored at the kernel layer. The application program framework layer obtains an original input event from the kernel layer, identifies a control corresponding to the input event according to the current position of the focus and uses the input operation as a confirmation operation, the control corresponding to the confirmation operation is a control of a magic mirror application icon, the magic mirror application calls an interface of the application framework layer to start the magic mirror application, and then the kernel layer is called to start a camera driver, so that a static image or a video is captured through the camera.

In some embodiments, for a display device with a touch function, taking a split screen operation as an example, the display device receives an input operation (such as a split screen operation) that a user acts on a display screen, and the kernel layer may generate a corresponding input event according to the input operation and report the event to the application framework layer. The window mode (such as multi-window mode) corresponding to the input operation, the position and size of the window and the like are set by an activity manager of the application framework layer. And the window management of the application program framework layer draws a window according to the setting of the activity manager, then sends the drawn window data to the display driver of the kernel layer, and the display driver displays the corresponding application interface in different display areas of the display screen.

In some embodiments, as shown in fig. 5, the application layer containing at least one application may display a corresponding icon control in the display, such as: the system comprises a live television application icon control, a video on demand application icon control, a media center application icon control, an application center icon control, a game application icon control and the like.

In some embodiments, the live television application may provide live television via different signal sources. For example, a live television application may provide television signals using input from cable television, radio broadcasts, satellite services, or other types of live television services. And, the live television application may display video of the live television signal on the display device 200.

In some embodiments, a video-on-demand application may provide video from different storage sources. Unlike live television applications, video on demand provides a video display from some storage source. For example, the video on demand may come from a server side of the cloud storage, from a local hard disk storage containing stored video programs.

In some embodiments, the media center application may provide various applications for multimedia content playback. For example, a media center, which may be other than live television or video on demand, may provide services that a user may access to various images or audio through a media center application.

In some embodiments, an application center may provide storage for various applications. The application may be a game, an application, or some other application associated with a computer system or other device that may be run on the smart television. The application center may obtain these applications from different sources, store them in local storage, and then be operable on the display device 200.

In some embodiments, display device 200 may also include a touch component 276 through which a user may touch interact with display device 200. The touch-sensing component 276 may be a layer of touch-sensing elements added on the display screen of the display 275, and the specific touch-sensing principle may be determined according to the actual interaction requirement. For example, a capacitive touch screen, a resistive touch screen, an infrared touch screen, a surface acoustic wave touch screen, or the like may be used according to the actual application scenario of the display device 200.

The touch assembly 276 may include a sensing unit provided on the display 275 and a signal processing unit provided in the display device. The sensing unit can be used for sensing touch operation of a user and converting the touch operation into an electric signal; the signal processing unit may perform processing on the generated electrical signal, including feature extraction, noise reduction, amplification, and the like.

Taking a capacitive touch screen as an example, the sensing unit may be a layer of transparent special metal conductive substance attached to the surface of the display screen glass of the display 275. When a finger or a palm of a user touches the conductive substance layer, the capacitance value of the touch point is changed, so that a touch signal is generated. The signal processing unit can receive the touch signal and process the touch signal to convert the touch signal into a digital command readable by the controller 250.

Generally, the interactive actions performed by the user on the touch screen may include clicking, long-pressing, sliding, and the like. In order to support more interactive modes, the touch screen can also support multi-touch. The more touch points the touch screen supports, the more interactive actions can be implemented accordingly. For example, a multi-finger click, a multi-finger long press, a multi-finger swipe, etc. may be implemented.

For different interaction actions, characteristics of the touch signal, such as a touch point position, a touch point number, a touch area, and the like, may be obtained for the generated touch signal. And judging the type of the touch signal according to the signal characteristics generated by the touch point, thereby generating a touch instruction. According to the position of the touch point, the touch position of the user, namely the position for executing the handing-out operation, can be detected; the number of fingers used in the touch interactive operation of the user can be determined through the number of the touch points; by judging the duration of the touch signal, whether the user performs a click operation or a long-time press operation can be determined; through the position change situation of the touch point, the sliding operation performed by the user can be determined.

For example, the touch component 276 may extract features of the touch signal after detecting the touch signal, and if the number of touch points in the touch signal is equal to 1, the duration of the touch signal is less than 0.5s, and the position of the touch point in the touch signal does not change, determine that the interaction action input by the current user is a single-finger click action, and accordingly may generate a touch instruction corresponding to the single-finger click action.

The touch component 276 may be connected with the controller 250 to send the generated touch instructions to the controller 250. Since the interactive process is a continuous process, the touch component 276 continuously sends touch commands to the controller 250 to form a data stream. To distinguish between different touch commands, the touch component 276 can generate touch commands according to the rules of one or more touch actions so that the controller 250 can receive complete and recognizable touch commands.

According to the touch input by the user, the controller 250 may execute different control programs according to the operating system interaction manner, and control the display 275 to display different user interfaces. In the embodiment of the present application, the user interface generally refers to a specific interface displayed on the display device 200, and may include a control interface, a play interface, and the like. A user may exercise interactive control with the display device 200 via the control apparatus 100 and/or the touch-sensitive component 276 via operating system interaction rules built into the display device 200 to enable presentation of different user interfaces on the display 275. Different user interfaces may have different UI layouts, i.e., include different control compositions.

Wherein, the control refers to specific display content for realizing user interaction control. For example: buttons, progress bars, scroll bars, text boxes, radio boxes, check boxes, links, and the like. The control can be displayed in different shapes, patterns and sizes according to the UI style characteristics of the operating system, and can form a function area at different positions in the interface according to the corresponding function. For example, as shown in fig. 6, a status bar at the top, a menu switching area at the middle upper portion, and content areas at the middle and lower portions may be included in the control homepage. A number of commonly used status controls or icons may be included in the status bar, such as a mode switch button, a search box, a VIP buy/log in status button, a message bar, and the like. A plurality of controls for indicating different menus, such as a "my" menu, a "channel" menu, etc., may be included in the menu switching region. A plurality of asset play link controls may be included in the content area.

The user can execute corresponding control actions through the control. For example, the user can jump from the currently displayed control home page interface to the corresponding asset play interface by clicking any asset play link control. With respect to the display device 200 in the embodiment of the present application, since the touch component 276 is built in, the interaction can be realized through a touch action.

In practical applications, the user can input various touch actions through the touch component 276, and the touch component 276 forms a touch instruction by detecting the input touch actions. According to different input touch actions, different touch commands are formed, and generally, the touch commands can include multiple types. For example, a single-click touch command, a multi-click touch command, a long-press touch command, a slide touch command, and the like. And further generating a multi-finger touch instruction according to the number of corresponding touch points in the touch action, for example, a multi-finger click instruction, a multi-finger slide instruction, a multi-finger long-press instruction, and the like.

The touch command generated by the touch component 276 can be acquired by the controller 250 to execute the corresponding interactive control action according to the rule set in the operating system. Different touch instructions may correspond to different control actions. For example, a single-click touch instruction on a media asset play link control may be used to open the play link to obtain media asset data; the long-press touch instruction on one functional icon can be used for indicating entering an editing state, so that the position of the functional icon can be adjusted through the sliding touch instruction in the editing state.

It should be noted that, in practical applications, the same touch instruction may have different control actions in different controls. For example, a click touch instruction input on the asset link control may implement a control action of opening a link, that is, jump to an asset detail page or a play interface, and a click instruction input on the volume control may implement setting the current volume of the display device 200 to a volume corresponding to a click position.

Since touch actions are typically performed by a user with a finger on the display 275. Accordingly, the touch control device is limited by the influence of the user's arms, height and other factors, and the area where the user can perform the touch control operation is limited. For example, an average adult user's arm length is 650mm, it is convenient to perform a touch area for a single arm operation that is no more than 650 x 650mm on the screen. And for the two-arm operation, an area in which touch is easily performed is an area of not more than 1600 × 650mm on the screen.

However, as the screen size of the display 275 in the display device 200 gradually increases, it is often difficult for an area convenient for a user to perform touch control to cover the entire display area. For example, if the screen size of the 65-inch smart television is 1459 × 841mm, the user cannot touch the lower right corner area when operating in the 650 × 650mm area near the upper left corner due to the influence of height and standing position, which is inconvenient for the user to complete touch input.

In order to facilitate the user to complete the touch input, some embodiments of the present disclosure provide a touch-assisted interaction method, which can be applied to a display device 200, where the display device 200 at least includes a display 275, a touch component 276 and a controller 250, and the display 275 and the touch component 276 are connected to the controller 250. Among other things, the touch component 276 can communicate the detected touch action to the controller 250 to cause the controller 250 to control the display content in the display 275.

In the process of controlling the display 275 to display specific content, the touch-assisted interaction method may be implemented by configuring a control program in the controller 250 and executing the control program by the controller 250. As shown in fig. 7, the touch assistance interaction method includes the following steps:

s1: and acquiring a touch instruction which is input by a user and used for executing touch assistance.

The user can input a touch action on the touch component 276, i.e. the touch screen, and as the touch action is input, the touch component 276 can generate a corresponding electrical signal, so as to detect the input touch action. The generated electrical signal is sent to the controller 250 or a built-in microprocessor for judgment. The controller 250 or a built-in microprocessor may determine the specific touch action by analyzing the specific value and the variation rule of the electrical signal, so as to form a touch instruction and send the touch instruction to the controller 250.

By analyzing the electrical signal, parameters in the touch action, including touch point position, number of touch points, duration of touch operation, etc., can be determined. The position of the touch point where the user executes the touch instruction can be determined, and whether the user inputs the slide instruction can be determined by the change of the position of the touch point. The number of touch points may determine that the user is inputting with a single finger or multiple fingers. Through the touch duration, it can be determined that the user inputs a click, a long press, multiple clicks and other touch actions. Obviously, the parameters can be comprehensively analyzed to determine more complex touch instructions.

The controller 250 may receive various touch commands input by the user through the touch component 276, such as clicking, long-pressing, sliding, and the like. In order to implement touch assistance, a touch instruction may be set as a touch instruction for performing touch assistance by setting a preset determination rule in an operating system. Therefore, after receiving the touch instruction, the controller 250 may determine the touch action corresponding to the touch instruction, so as to determine whether the touch instruction input by the user is used for performing the touch assistance interaction.

Because some touch commands are frequently used and some are not frequently used according to different usage habits and operation difficulties, in practical applications, the touch commands for performing touch assistance should be different from those for other purposes. In addition, the frequency of the touch instruction for executing the touch assistance interaction method is low relative to the frequency of the touch instruction for opening, adjusting and other basic functions, so the touch instruction for executing the touch assistance can be set as an unusual touch instruction. For example, the touch instruction for performing touch assistance may be a multi-click instruction, a long-press instruction, a multi-finger touch instruction, and the like.

S2: and responding to the touch instruction, and generating a mapping window according to the current user interface.

After obtaining the touch instruction for performing touch assistance, the controller 250 may generate a mapping window according to the current user interface. The mapping window may be content displayed in an area of the current user interface that is not convenient for the user to operate, so that the user may operate through the mapping window without moving to another location. Therefore, all or part of the controls in the current user interface are included in the mapping window, and the controls in the mapping window and the controls in the current user interface have an association relationship.

To generate the mapping window, after acquiring the touch command, the controller 250 may acquire the display content of the current user interface, so as to generate a mapping window according to the acquired display content. The content in the mapping window may include all of the content in the current user interface. For example, if the current user interface is a control homepage, the content of the entire user interface may be included in the mapping window, i.e., the screen content in the mapping window is the same as the content of the user interface, and only the window size is smaller than the size of the current user interface.

In some embodiments, to enable full display of the current user interface content, the screen scale of the mapping window may be the same as the display scale of the current user interface, e.g., both screen scales are 16: 9.

The content in the mapping window may also include only a portion of the content that does not facilitate the user to perform the interactive operation region. For example, when the current user interface is a control homepage, and the current operation position of the user is determined to be close to the left area of the screen, the right area content which is inconvenient for the user to perform the touch interaction operation can be displayed in the mapping window. Obviously, the mapping window only needs to be able to display the area which is inconvenient for the user to operate completely, so the mapping window may not necessarily maintain the same picture scale as the current user interface.

It should be noted that, in order to enable the user to perform the touch interaction operation in the mapping window without moving the position, the size of the mapping window should be controlled within the area range convenient for the user to operate. For example, the mapping windows are each less than 650mm in width and height so that a user can complete a one-handed operation within the mapping window.

S3: and displaying the mapping window in the relevant area of the touch instruction.

After generating the mapping window, the controller 250 may control the display 275 to display the mapping window in the area associated with the touch command. The area associated with the touch instruction may be an area related to an input position of the touch instruction. For example, the current display frame range may be divided into a plurality of preset partitions according to the display content, and the associated area is the same preset partition as the touch instruction. Obviously, the associated area is also in an area where the user is convenient to perform touch operation.

In order to implement touch interaction operation in the mapping window, the mapping window may be displayed on the topmost layer of the screen. For example, as shown in fig. 8, the mapping window may be displayed in the frame as a floating window to avoid the original content of the frame from blocking the mapping window. When the mapping window maintains the state of the floating window, the display position can be adjusted through further touch interactive operation. For example, a sliding touch instruction may be input through the top of the mapping window to drag the mapping window to another position in the display screen.

According to the technical scheme, the touch-control assistance interaction method can realize that when a user needs to perform operation in a region with a longer distance, a touch-control instruction for performing touch-control assistance interaction is input through a specific touch-control action, so that the display device 200 can generate a mapping window according to a current user interface after acquiring the touch-control instruction, and display the mapping window in a relevant region convenient for the user to operate, so that the user can complete the touch-control action through the mapping window. The method is more in line with the operation habit of the user, and can implement touch operation on the whole user interface on the premise of not moving the position.

Based on the above embodiment, the user can display the mapping window by inputting a specific touch instruction at any time of the touch operation. Accordingly, the controller 250 may determine for each touch instruction received whether it is an instruction for performing touch-assisted interaction. To this end, in some embodiments, as shown in fig. 9, the step of obtaining the touch instruction for performing touch assistance input by the user further includes:

s101: monitoring a touch action input by a user;

s102: and if the touch action is the same as the preset touch action, generating a touch instruction for executing touch assistance.

With the touch action input by the user, a touch event may be generated in the operating system. The controller 250 may listen to the generated touch event in real time to determine the touch action input by the user. The touch actions include long-press actions, multi-click actions, sliding actions, multi-finger actions, click actions input at a preset position, and the like, and other types of touch actions may also be included according to the type of the touch component 276. By detecting, if it is determined that the touch action is the same as the preset touch action, a touch instruction for performing touch assistance is generated to trigger the controller 250 to execute a program related to generating the mapping window.

Generally, a touch event may include touch information such as a press-down point and a lift-up point, and accordingly, has related information such as a press-down time, a press-down position, a lift-up time, and a lift-up position. touch information contained in the touch event may be obtained via an electrical signal generated by touch component 276. For example, the touch action is detected by the touch component 276, so that the voltage of the touch component 276 at the touch position changes to form an electrical signal. After the formed electrical signal is sent to the controller 250, the controller 250 may identify the voltage variation in the electrical signal, determine the position and time of the voltage variation, and form a touch event. The formed touch event may include representation by a specific event code, for example, "motionevent.action _ DOWN" represents a touch event corresponding to a press point, and "motionevent.action _ UP" represents a touch event corresponding to a lift point.

The preset touch actions may be uniformly set according to an interaction policy in the operating system, that is, different trigger modes may be set in different display devices 200 to display the mapping window. How to determine whether the touch action is the same as the preset touch action is described in the following by using several specific examples:

for example, the preset touch action may be a long-press touch action, that is, triggered by a long-press mode.

The controller 250 may monitor Touch events, monitor "motionevent.action _ DOWN" and record a pressed position and time when a user touches a finger, and monitor "motionevent.action _ UP" events and record a lifted position and time when the user lifts the finger. By setting the time threshold and the distance threshold of the long press, if the distance between the two recorded positions is smaller than the distance threshold and the time interval between the two recorded positions exceeds the time threshold, it is determined that the touch action input by the user is the long press action, and therefore it is determined that the input action is the same as the preset touch action, that is, the input touch instruction is a touch instruction for performing touch assistance.

In the second example, the preset touch action may be a double-click touch action, that is, triggered by a double-click method.

Controller 250 may record the first and second click events through a control program and set a time threshold for successive clicks. Action _ DOWN is monitored when the user touches the click for the first time by monitoring Touch events, marking the start of the first click event. When the user lifts the hand, the "motionevent. action _ UP" event is monitored, the end of the first click event is marked, and the end time is recorded. And then monitoring a second click event, if the second click event is started, recording the start time of the second click, and when the second click event is sent, ending the second click event, calculating the time difference of the two click events, and if the time difference is smaller than a set threshold, determining that the user inputs a double-click touch action, so that the input action is determined to be the same as the preset touch action, namely the input touch command is a touch command for executing touch assistance.

In the third example, the preset touch action may be a multi-finger touch action, that is, triggered by a multi-finger manner.

As shown in fig. 10, the detection procedure in the controller 250 may be triggered after listening for a "motion event. When the current event is triggered, the number of trigger fingers can be obtained through a command of 'getPointerCount ()'. If five fingers are defined, when the "getPointerCount ()" is 5, it is determined that the user inputs a multi-finger touch action, and thus it is determined that the input action is the same as the preset touch action, and it is determined that the input touch instruction is a touch instruction for performing touch assistance.

For the multi-finger touch action, the corresponding touch condition on each touch point can be further judged, so that more complex gesture actions can be determined. Such as a pinch gesture in which two fingers slide inward at the same time, a spread gesture in which two fingers slide outward at the same time, a rotate gesture in which two fingers slide circularly in the same direction, and the like.

In example four, the preset touch action may be a sliding touch action, that is, triggered by a sliding manner.

As shown in fig. 11, the sliding touch manner may set a specific input action limit to distinguish the sliding touch manner of other functions. Such as at the screen boundary position, the mapping frame is triggered by sliding. Similarly, the controller 250 records coordinate points in the "motion event.action _ DOWN" and "motion event.action _ UP" events by monitoring Touch events, such as single finger sliding, and determines the current sliding direction according to rules, including left sliding, right sliding, UP sliding, DOWN sliding, and the like, and when the recorded coordinate points are in an area close to the screen boundary, it is determined that the user input action is the same as the preset Touch action, and it is determined that the input Touch command is a Touch command for performing Touch assistance.

And a sliding touch action can be completed by inputting a specific path through multiple fingers. For example, as shown in fig. 12, 13, input may be accomplished by a double finger inward swipe to implement a spread-out gesture motion. Alternatively, as shown in FIG. 14, the input is accomplished by a two finger data spin slide command. Alternatively, as shown in fig. 15, the input of the touch action is completed by sliding in the same direction.

In example five, the preset touch action may be a click action input at a preset position, that is, a touch instruction for performing touch assistance is input through a part of the control of the UI interface.

As shown in fig. 16, a floating touch menu may be displayed on the user interface, and a shortcut key control for controlling assistance may be included in the floating touch menu, through which a user may input a click touch action. Similarly, the controller 250 records coordinate points and time in the event "motionevent.action _ DOWN" and "motionevent.action _ UP" respectively by monitoring Touch events, and determines that the user inputs a Touch instruction for performing Touch assistance if the coordinate points recorded twice are both within the range of the manipulation assistance key and the time recorded twice is less than a preset time threshold.

It should be noted that, since the Touch component 276 enables the controller 250 to monitor the Touch event, the Touch manner in the above example can be implemented, and a custom Touch action can also be performed, that is, the form is defined according to the requirement of the display device 200 and the requirement of the user, and is not limited to the above forms.

According to the technical scheme, the embodiment can detect the touch action of the user according to the touch event by monitoring the touch event corresponding to the touch operation of the user, and determine that the user inputs the touch instruction for executing touch assistance when the touch action is the same as the preset touch action. Therefore, the user can trigger and generate the mapping window through a specific touch action on any interface, so that the user operation is facilitated.

After obtaining the touch instruction for performing touch assistance, the controller 250 may generate a mapping window according to the current user interface. That is, in practical applications, after the controller 250 monitors the Touch event, the Touch event is analyzed, and if it is determined that the same action as the preset Touch action is input, the mapping window is drawn, and the drawn mapping window may have different forms according to different application environments, including but not limited to the following:

for example, the mapping window may include the entire contents of the current user interface. In some embodiments, the step of generating a mapping window from the current user interface comprises:

s211: executing screenshot on the whole picture of the current user interface;

s212: zooming the screenshot result to generate a global thumbnail;

s213: traversing the positions of all controls in the current user interface;

s214: and establishing an association relation between each control and a pixel point in the global thumbnail according to the position of the control in the current user interface, and generating the mapping window.

To generate the mapping window, controller 250 may first perform a screenshot in the current user interface by executing a graphical screenshot program. The intercepted pattern includes all the display contents of the current user interface. For example, if the current user interface is a control home page, the captured image includes all the graphics frames in the status bar, menu bar, and content area. After screenshot, the controller 250 may also reduce the captured image in equal proportion to form a global thumbnail. The reduced scale may be determined according to the size of the mapping window, that is, the reduced global thumbnail size is consistent with the preset mapping window size.

After the global thumbnail is obtained, an association relationship between the thumbnail and a control on the corresponding user interface can be further established, that is, the association relationship between each control and a pixel point in the global thumbnail is established by traversing the position of each control in the current user interface, so as to generate a mapping window. After the association relationship is established, if a user inputs a touch action at a pixel point position corresponding to the mapping window, the input touch action can be associated to the user interface according to the established association relationship, which is equivalent to inputting a touch instruction on the user interface.

According to the technical scheme, the method for generating the mapping window in the embodiment can be used for constructing the basic pattern of the mapping window in a mode of intercepting the global thumbnail, so that a user can conveniently implement touch operation. And then, by establishing an incidence relation between the pixel points in the mapping window and the controls in the user interface, the mapping window can support the touch operation of the user. Therefore, the method for generating the mapping window can realize multi-window display and support touch-control assistance operation under the condition of occupying less processing capacity of the controller 250.

In some embodiments, if the mapping window includes the entire contents of the current user interface, the step of generating the mapping window according to the current user interface may include:

s221: acquiring the size of a display area of a mapping window;

s222: and executing a display program which is the same as that for displaying the current user interface according to the size of the display area, and generating the mapping window.

In the operating system of the display apparatus 200, a display program for each user interface may be built in, including a set display UI frame, display contents, a rendering program, and the like. These display programs are called along with the interaction of the user to construct and form a specific display screen. Therefore, in this embodiment, a specific display window may be generated by using a display program to form a mapping window.

Obviously, the generated mapping window is small relative to the size of the current user interface so that the user can perform touch interaction operation. Therefore, after acquiring the touch instruction for performing touch assistance, the controller 250 may first acquire the size of the display area of the mapping window, and then execute the display program identical to the current user interface according to the size of the display area, so as to generate a mapping window having the same content as the current user interface but a smaller size.

For example, if the current display screen is a control homepage, the preset mapping window size is 650 × 365mm after receiving the touch instruction for performing touch assistance. Extracting a related display program for controlling the homepage from the operating system, namely extracting a UI layout frame for controlling the homepage; and then, corresponding display content is acquired, and the display content may be acquired from the server 400, or the content acquired by the display device 200 may be directly extracted. Finally, the controller 250 may execute a rendering program to generate a display screen having a size of 650 × 365 mm.

It can be seen that, in the method for generating a mapping window provided in the foregoing embodiment, a user interface having the same content as the current user interface but a smaller size may be generated on the mapping window by using a display program in an operating system, so that a user may directly perform an interactive action on the mapping window, and after the interactive action is performed, directly run a related control program, such as a jump interface, adjust running data, and the like.

It should be noted that, since the mapping window and the current user interface are two same interfaces, when the display content changes due to the interaction performed on the mapping window, the user interfaces other than the mapping window also change accordingly. In order to reduce the calculation load of the controller 250, the display time of the mapping window may be set, and the mapping window may be automatically closed after the mapping window is displayed for a certain time. For example, the preset duration may be set to 20s, that is, after the user calls the mapping window or within 20s after the last operation in the mapping window, the mapping window is automatically closed if the user does not perform the touch operation any more.

Because the display range size of the mapping window is generally smaller, when the display content in the current user interface is more or the control graph is smaller, the display content on the mapping window is easy to be unclear or inconvenient to operate due to the smaller graph, and therefore, for such a user interface, only part of the content can be displayed, as shown in fig. 17, so that the content in the mapping window is clearer and the user operation is more convenient. That is, in some embodiments, the mapping window may only display a part of the content in the current interface, and the step of generating the mapping window according to the current user interface further includes:

s231: acquiring a direct operation area corresponding to the touch instruction;

s232: executing screenshot on the indirect operation area of the current user interface;

s233: zooming the screenshot result to generate a local thumbnail;

s234: traversing the positions of the controls in the indirect operation area;

s235: and establishing an incidence relation between each control and a pixel point in the local thumbnail according to the position of the control in the indirect operation area, and generating the mapping window.

For the display screen of the display device 200, the user interface may be pre-divided into a plurality of partitions, and different partitions may correspond to different positions of the user, so that the user performs touch interaction operations at different positions. To implement the operation, the specific partition may be divided according to the screen size of the display device 200. For example, for a large screen display 275 of 65 inches or more, the display screen may be divided into two in the middle of the screen, i.e., including the left and right partitions.

While for a portion of the display device 200 it may assume different rotational states in an application, such as landscape and portrait states. Therefore, when the preset partition is divided, different partition dividing modes can be provided under different rotation states. For example, in the portrait state, the display screen may be divided into an upper partition and a lower partition at a middle position of the screen.

Therefore, after a touch instruction for executing touch assistance is received, a direct operation area corresponding to the touch instruction is obtained, wherein the direct operation area is a preset partition to which a finger lifting position in the touch instruction belongs, and other preset partitions outside the direct operation area are used as indirect operation areas. Obviously, the indirect operation area is far away from the operation position of the user, and the touch operation is not convenient to execute. For example, the controller 250 determines that the position of "motionevent _ action _ UP" is in the left partition by monitoring the touch event, and the left partition is a direct operation region and the corresponding right partition is an indirect operation region.

And similarly, screenshot is carried out on the display content in the indirect operation area according to the generation method of the mapping window, and the captured image is zoomed to generate a local thumbnail. And establishing an incidence relation between each control and a pixel point in the local thumbnail by traversing the position of each control in the indirect operation area and according to the position of each control in the indirect operation area, and generating a mapping window.

Therefore, the generated mapping window can comprise the content in the indirect operation area, the content in the indirect operation area is moved to the mapping window convenient for the user to operate, the displayed content is not excessively reduced, and the user can conveniently perform interactive operation on the mapping window.

In some embodiments, when the mapping window displays only a portion of the content in the current interface, the content displayed in the mapping window may also be customized. I.e. the step of generating a mapping window according to the current user interface, the controller is further configured to:

s241: acquiring the interface type of the current user interface;

s242: extracting a custom mapping area according to the interface type;

s243: executing screenshot on a user-defined mapping area of a current user interface;

s244: zooming the screenshot result to generate a local thumbnail;

s245: traversing the positions of the controls in the user-defined mapping area;

s246: and establishing an incidence relation between each control and a pixel point in the area thumbnail according to the position of the control in the user-defined mapping area, and generating the mapping window.

In order to perform touch operation, the content displayed in the mapping window should include controls, and the content and the number of the controls included in the mapping window are different for different interfaces. For example, the number of controls on the control homepage is large, and the content of the controls covers various situations, including icons on a status bar, menu entries, media asset links, and the like. The number of controls on the playing interface is small, and the controls generally include buttons related to playing control, such as pause/play keys, fast forward/fast backward keys, volume control bars, selection buttons, and the like. Thus, different custom mapping regions may be set for different types of user interfaces.

Controller 250 may obtain the interface type of the current user interface and determine the custom mapping region based on the user interface type. For custom mapping regions, they may be uniformly and automatically set by the operating system or server 400, or manually set by the user. For example, the custom area of the playing interface may not include a specific playing screen that is only displayed and rarely performs interactive operations, but only include a control button area at the bottom of the playing screen.

After determining the custom mapping region, controller 250 may generate the mapping window in the same manner as described above in other embodiments. Namely, the mapping window can be generated by intercepting the area thumbnail of the custom mapping area and traversing the positions of the controls in the custom mapping area to establish the association relationship between each control and the pixel point in the area thumbnail.

For example, as shown in fig. 18, after the user inputs a touch instruction for touch assistance on the playing interface, the controller 250 may detect the type of the current user interface, so as to obtain that the interface type of the current user interface is the playing interface. For the playing interface, the user usually only performs interactive operations on controls such as pause/play keys, fast forward/rewind keys, volume control bars, and selection buttons. Thus, the mapping window may include only the display content of the area in which the controls are located. The method comprises the steps of carrying out screenshot aiming at the areas where the controls are located, and establishing an incidence relation between a pattern in a mapping window and a current user interface by traversing the positions of the controls in the screenshot areas.

Since the playing interface usually has a separate touch interaction policy, for example, pausing/playing can be completed by double-clicking the display content area, fast forwarding/fast rewinding can be completed by sliding, and the like, the display content of the mapping window may not include these controls, only include the selection button area, thereby further simplifying the display content in the mapping window, and facilitating the user to complete the interaction operation.

Therefore, in the above embodiment, the user-defined mapping region may be determined by detecting the interface type of the current user interface, so that the picture in the user-defined mapping region is displayed in the mapping window, and the association relationship is established so that the touch operation on the mapping window can be associated with the user interface, thereby implementing the touch assistance operation. In addition, because the user-defined area for mapping can only be used for the part with the control, the mapping window can be displayed through a smaller area, and the excessive shielding of the mapping window on the user interface is relieved.

It should be noted that the generated mapping window may also be associated with a touch area according to a specific user interface, or be combined with other local or custom areas to form a mapping window more beneficial to user operations. For example, as shown in FIG. 19, the lower area of the current user interface is a list of thumbnails, supporting slide and click events; and the area above the thumbnail list is a picture detail display area, and sliding and rotating control is supported. In the display process, the display area does not limit the operation control area, and can be controlled at any position. Therefore, two corresponding partitions can be formed in the mapping window, that is, the two partitions can be mapped into the touch pad and the list mapping area.

Similarly, after the mapping window is generated, the user can perform left-right sliding and clicking event control in the list mapping area, and then the mapping window detects the user control to issue an instruction, so that the list switching is realized; and performing operation in the touchpad area, such as rightward rotation operation, issuing an instruction after the touchpad monitors that the touchpad performs rightward rotation, and performing rightward rotation of the picture after the front-end full-screen page monitors the rightward rotation.

After the map window is generated, the map window may be displayed on the top of the user interface via the display 275, and in order to facilitate the user to perform further touch operations, the display position of the map window should be in an area convenient for the user to operate. In some embodiments of the present application, in order to display the mapping window in the area convenient for operation, the step of controlling the display position of the mapping window according to the position of the touch instruction input by the user, that is, displaying the mapping window in the area associated with the touch instruction further includes:

s310: monitoring a touch action input by a user, and recording a finger lifting position in the touch instruction;

s320: and displaying the mapping window by taking the finger lifting position as a reference.

The controller 250 may monitor a touch event when the user inputs a touch instruction in real time, and record a finger lifting position corresponding to the touch event, that is, a position of "motionevent. Generally, the position where the user's finger is lifted is within an area convenient for the user to operate. Accordingly, the controller 250 may display a mapping window on the display 275 with reference to the finger-up position.

The mapping window may be displayed near the finger-lifted position based on the finger-lifted position as a reference point. The displayed mapping window may be made to cover the finger-up position. For example, the center or any point of the mapping window is made to be the same as the coordinates of the finger lift position; the displayed mapping window may also be located in a specific area near the finger lift position.

That is, as shown in fig. 20, in some embodiments, the step of displaying the mapping window based on the finger-lifted position further includes:

s3211: calculating the distance between the finger lifting position and the edge position of the display screen;

s3212: if the distance is larger than or equal to a judgment threshold value, displaying the mapping window by taking the finger lifting position as a central point;

s3213: and if the distance is smaller than the judgment threshold, translating the mapping window by taking the finger lifting position as a starting point so as to completely display the mapping window.

In this embodiment, the display of the mapping window is performed with the finger-lifted position as the center under normal conditions. Before the mapping window is displayed, the lifting position of the finger can be judged, and whether the area corresponding to the lifting position of the finger has enough display space to completely display the mapping window is determined. If the display is complete, directly taking the finger lifting position as the center to display the mapping window; if the display is not complete, the mapping window is translated by taking the finger-lifting position as a starting point until the display is complete.

Specifically, the coordinates of the finger lifting position can be represented by pixel points. For example, as shown in fig. 21, a planar rectangular coordinate system is constructed with the upper left corner of the display screen as the origin and the number (or distance) of pixels from the left side frame and the top frame as the unit length, and the finger-lifted position coordinate P (x) is represented by the constructed rectangular coordinate system₀，y₀)。

In acquiring the finger-lifted position coordinate P (x)₀，y₀) Thereafter, the distance between the finger lift position and the edge position of the screen of the display 275 may be calculated in conjunction with the current screen size (W H) of the display 275, including: the distance LL between the finger lifting position and the left side frame is x₀(ii) a The distance LR between the finger lifting position and the right side frame is W-x₀(ii) a The distance LT between the finger lifting position and the top frame is y₀(ii) a The distance LB between the finger lifting position and the bottom frame is H-y₀。

According to the calculated distances, the distances can be respectively compared with the judgment threshold value so as to determine whether the mapping window can be completely displayed when the current finger lifting position corresponds to the central area. Wherein the determination threshold may be determined according to a position of the mapping window, and may have different determination thresholds in the lateral and longitudinal directions. For example, the horizontal determination threshold is 1/2 of the mapping window width, and the vertical determination threshold is 1/2 of the mapping window height.

By comparing the calculated distances in the various directions with the judgment threshold values in the various directions, the display mode of the mapping window can be determined. If the distances in all directions are larger than or equal to the judgment threshold, the mapping window can be completely displayed, namely the mapping window is displayed by taking the finger lifting position as a central point. If the distance in any direction is smaller than the judgment threshold, it is determined that the mapping window cannot be completely displayed in the corresponding direction, and the mapping window can be translated to the direction opposite to the direction to completely display the mapping window. For example, if the distance LL between the lifted position of the finger and the left side frame is less than the lateral judgment threshold LX, the mapping window is shifted to the right by a distance greater than or equal to LX-LL.

According to the technical scheme, the embodiment can realize that the mapping area is drawn by taking the touch operation as the center under the normal condition when the mapping window is displayed. And when the position is close to the edge position, the peripheral area is drawn by taking the edge point as the standard. The display mode not only can completely display the mapping window, but also can enable the display position of the mapping window to be associated with the touch action of the user, so that the user can conveniently execute subsequent operations.

In some embodiments, the step of displaying the mapping window based on the finger-lifted position may further include:

s3221: acquiring a preset partition to which the finger lifting position belongs;

s3222: and displaying the mapping window in the preset partition.

To display the mapping window, the display screen may be divided into a plurality of preset partitions in accordance with the screen size of the display 275, and one area is designated in each preset partition for displaying the mapping window. Obviously, the area for displaying the mapping window is required to facilitate the user to perform touch interaction operation, and to reduce the occlusion of the display and the control in the current user interface as much as possible.

For example, the screen of the display 275 may be divided into two preset partitions, namely a left area and a right area, where the display position of the mapping window is close to the upper left corner of the display 275, so as to facilitate the user to perform a touch operation when the user is close to the left area. Similarly, the mapping window in the right region is displayed near the upper right corner of the display 275.

According to the partition mode, the preset partition to which the touch instruction belongs can be obtained through the recorded finger lifting position, and the mapping window is displayed in the preset partition to which the touch instruction belongs. For example, if the recorded finger-up position coordinates are located within the left area, the mapping window is displayed in the area near the upper left corner in the left area.

Therefore, the display position of the mapping window is controlled in a preset partition mode, and the mapping window can be ensured to be in the same position when being called each time. And the influence of the user operation on the display position can be reduced. For example, when the user performs an interactive operation near the left area, the extended arm inputs a touch instruction for performing touch assistance near the middle area, and the mapping window is still displayed at the most appropriate position corresponding to the left area, thereby alleviating the influence of the individual operation.

Based on the touch assistance interaction method provided in the foregoing embodiments, some embodiments of the present application further provide a display device 200. Including a display 275, a touch-sensitive component 276, and a controller 250. Wherein the display 275 is configured to display a user interface, the touch-sensitive component 276 is configured to detect a touch input by a user, and the controller 250 is configured to perform the following procedural steps:

s1: acquiring a touch instruction which is input by a user and used for executing touch assistance;

s2: responding to the touch instruction, and generating a mapping window according to the current user interface;

The mapping window comprises all or part of controls in the current user interface, and the controls in the mapping window and the controls in the current user interface have an association relationship. As can be seen, the display device 200 provided in this embodiment can be used to implement the touch assistance interaction method provided in the above embodiments. The touch component 276 may be disposed on the display 275 to form a touch screen to detect a touch action of the user in real time, and convert the detected touch action into a touch command to be sent to the controller 250. The controller 250 generates a mapping window according to the current user interface in response to the received touch command, thereby controlling the display 275 to display the mapping window in the area associated with the touch command.

After the mapping window is displayed, the user can perform control operation in an area inconvenient to operate by means of the mapping window by inputting a touch instruction on the mapping window again. Therefore, as shown in fig. 22, in order to implement touch-assisted interaction, in some embodiments of the present application, a touch-assisted interaction method is further provided, which includes the following steps:

s4: and acquiring an action instruction input by a user on the mapping window.

Obviously, the mapping window includes all or part of the controls in the current user interface, and the controls in the mapping window and the controls in the current user interface have an association relationship. I.e. the mapping window is the mapping window generated by any of the embodiments described above. After the mapping window is displayed, the controller 250 may perform a position determination for each touch input by the user to determine whether the input position is in the mapping window area or the user interface area. And if the input touch action is positioned in the mapping window, determining that the action instruction is input on the mapping window by the user.

The touch action position can be judged according to the finger pressing action position or the finger lifting position, and the finger pressing action is the starting action of all touch actions and can reflect the operation purpose of the user, so the finger pressing action position can be preferably used as the position of the touch action. The action command may also include a click action, a long press action, a multi-click action, a slide action, and so on. Each form of action can realize different control actions by acting on different controls, so that touch interactive operation is realized.

S5: and in response to the action instruction, extracting the touch position of the action instruction in a mapping window.

After obtaining the action instruction, the controller 250 may extract its touch position in the mapping window in response to the action instruction. Since the finger of the user is usually in surface contact with the touch component 276, the touch action may usually cover a plurality of pixel points in the mapping window, and thus the touch position of the action instruction in the mapping window may be a set formed by the plurality of pixel points. For the sliding touch action, since the passing area covered in the sliding process belongs to the touch action, the touch position can also include all the pixel points of the passing area within the duration time of the touch action.

S6: and executing the control action corresponding to the touch position in the current user interface according to the incidence relation.

After extracting the touch position of the action instruction in the mapping window, the controller 250 may further execute a control action corresponding to the mapping window according to the association relationship between the mapping window and the user interface. For example, a user inputs a click action command in the mapping window, and a touch position corresponding to the action command is positioned on a media asset link control graph positioned in a lower right corner area of the mapping window. And then according to the incidence relation between the mapping window and the user interface, the click action instruction is associated to a media asset link control positioned in the lower right corner area in the user interface so as to play the media asset. Equivalently, the user directly inputs a click touch action on the media asset link control of the user interface, so that the user can execute touch operation in an inconvenient operation area without moving a standing position.

Based on the display device 200, further touch interaction operation can be performed after the mapping window is displayed. For example, the user may manipulate the display device 200 to launch a "mirror" application, which may obtain an image of the user through an image capture module such as a camera and display the image in a picture frame. In the user interface of the "look at the mirror" application, some auxiliary controls such as "change clothes" may also be included for adjusting the displayed image content. Namely, after the user clicks any button of 'changing clothes', adding the clothes pattern corresponding to the control on the displayed image.

Due to the fact that the clothes are various, the number of the buttons for changing clothes is large, namely, a user cannot touch a part of buttons, and therefore the user can call the mapping window through a touch instruction. The mapping window may include at least which "change clothes" buttons are not accessible, so that after the mapping window is displayed, the user can click on any button area in the mapping window.

When the user clicks the "change clothes" button region located at the lower right corner on the mapping window, the controller 250 may obtain the action command, extract the touch position of the action command in the mapping window, and associate the click command with the "change clothes" button located at the lower right corner in the application interface. Corresponding to the user inputting a click command on the "change clothes" button located at the lower right corner, so that the clothes pattern corresponding to the button can be added to the frame area.

As the user performs a touch action on the mapping window, the user interface displayed on the display 275 will also send changes. That is, under a partial touch action, the displayed content needs to jump to display different user interfaces, and under a partial touch action, the display state of the control is adjusted, so that the user can execute other touch operations. Therefore, in some embodiments, after the control action corresponding to the touch position in the current user interface is executed, the method further includes the following steps:

s701: detecting the image contents of the mapping window and the current user interface;

s702: and if the mapping window is inconsistent with the picture content of the current user interface, refreshing the display content of the mapping window.

In this embodiment, the controller 250 may detect the image contents of the mapping window and the current user interface within a preset time after the control action is executed each time, or detect the image contents of the mapping window and the current user interface according to a set frequency, and compare the image contents of the mapping window and the current user interface after the detection is completed. If the picture contents are consistent, namely the control action does not change the specific contents in the current user interface, continuing to maintain the current display contents of the mapping window; and if the detected picture content is inconsistent, refreshing the display content of the mapping window to make the picture on the mapping window consistent with the user interface.

For example, as shown in fig. 23, if the current user target is to view "application 18" in the application interface, the user performs a long-press touch manipulation at the position of the icon in the lower right corner of the mapping window. The controller 250 judges the operation of the current user by monitoring Touch events, if the event is a long-time press event, the event is downloaded, namely, a control action corresponding to the Touch position in the current user interface is executed, and two control contents of unloading and detail are displayed on the application icon of the application 18 by executing the control action.

After the control action is executed, whether the mapping interface changes relative to the user interface or not can be detected at regular time through a timer, if the mapping interface changes, the mapping window is refreshed, and the timing is finished. The topActivity can be obtained by a correlation method of ActivityManager, and whether the front page changes can be judged.

Similarly, the controller 250 may continue to perform Touch event detection in real time in the mapping window, and if an event trigger is detected, perform event judgment, and if a user clicks a "details" position of the "application 18", open a details page of the application 18. And then determining that the detected picture content is inconsistent by detecting the picture content of the mapping window and the current user interface, and refreshing and displaying the mapping window as a detail page of the application 18. The specific refreshing process may be the same as the above-described manner of generating the mapping window, and is not described herein again.

Based on the above touch-assisted interaction method, a display device includes a display 275, a touch component 276 and a controller 250. Wherein the display 275 is configured to display a user interface, the touch-sensitive component 276 is configured to detect a touch input by a user, and the controller 250 is configured to perform the following procedural steps:

s4: acquiring an action instruction input by a user on a mapping window, wherein the mapping window comprises all or part of controls in a current user interface, and the controls in the mapping window and the controls in the current user interface have an incidence relation;

s5: in response to the action instruction, extracting a touch position of the action instruction in a mapping window;

As can be seen from the foregoing technical solutions, the display device 200 and the touch-assisted interaction method provided in the foregoing embodiments may enable the controller 250 of the display device 200 to extract a corresponding touch position in response to an action instruction by inputting the action instruction on the mapping window after the mapping window is displayed, so as to execute a control action corresponding to the touch position in the current user interface according to the association relationship. The method can equivalently implement the operation on the mapping window in the current user interface through the incidence relation between the mapping window and the control in the current user interface, so that the user can complete the operation in the whole user interface in the area convenient for operation, and the user experience is improved.

The embodiments provided in the present application are only a few examples of the general concept of the present application, and do not limit the scope of the present application. Any other embodiments extended according to the scheme of the present application without inventive efforts will be within the scope of protection of the present application for a person skilled in the art.
