Description

Split screen display control method for intelligent terminal

Technical Field

The invention relates to a control method for display of an intelligent terminal, in particular to a split-screen control method for an intelligent terminal display.

Background

In the current society, the mobile intelligent terminal can provide various functions and services (social contact, entertainment, photographing, multimedia data transmission, webpage news browsing and the like) so as to meet the diversified demands of users. But the existing single display screen can not meet the requirements of multiple users at the same time. For example, when playing the video streaming media, the user needs to reply immediately after receiving a short message or a WeChat prompt, once switching to enter short message or WeChat reply software, the original video streaming media playing can automatically quit, and the user needs to re-enter a video streaming media playing interface after completing information reply, so that a plurality of clicking steps are required to be executed in the process, and the original read data or played advertisements are forced to be transmitted once again. When text information needs to be input in social software, web pages need to be browsed for information searching, however, frequent switching is needed between two different applications of text input and web page browsing, and multiple clicking steps are needed in the switching process, so that a large amount of time is wasted on switching between the two applications, and the efficiency is seriously affected. Real-time online games with stricter requirements on response time cannot be switched frequently, once the real-time online games are switched into other applications for information reading or replying, the situation in the games can be changed greatly when the real-time online games return to the games, and the game experience is seriously influenced. Therefore, the above-mentioned various practical application scenarios all require that multiple Applications (APPs) are displayed and operated simultaneously on the same mobile phone or other intelligent terminals.

With the progress of semiconductor and display manufacturing processes, the size of a display screen of an existing intelligent terminal is larger and larger, the size of a mobile phone screen is generally larger than 5 inches, and the size of a display screen of an iPad \ automobile entertainment terminal and the like is larger than 8 inches. On the other hand, the resolution in the display screen is higher and higher, and characters or pictures displayed in the display screen can still be clearly identified when the size is small after the characters or the pictures are zoomed. This trend makes it possible to display and operate different applications simultaneously on the same display screen.

In recent years, smart phones having large-sized touch screens have been widely used, and smart phones having the same thereinA representative operating system is Google-derived Android (Android)^TM) IOS by systems and apple Inc^TMAnd (4) operating the system. Each mobile phone manufacturer adopting the android system continuously improves versions according to respective design requirements so as to improve operation convenience. Different operating systems are slightly different in specific running program settings, but in most operating systems, when switching between different applications, the current window is closed first, then the next required application window is found and opened on the main screen (desktop), and the next application is clicked to enter. Or the thumbnails of all applications in the open state can be checked through a special trigger button, and the applications are selected to enter the application, so that the switching of the applications is completed at least by 3 steps regardless of the requirement of the mode, time and labor are wasted, and the operation burden of a user is increased. In order to solve the above problems, the android operating system includes a split screen setting function, but the setting needs to be performed in a setting menu in multiple steps to complete the setting of split screen display, and the system has a deep setting entry and a complicated use method, so that the actual use ratio is low, and users complain a lot. After the split screen setting is completed, the following steps are required in real implementation: 1. a plurality of tasks exist in the recent task list; 2. pressing a 'latest task' button for a long time to enter a split screen mode; 3. and starting another application to be used under the recent task list. The operation of entering the split screen by long pressing a certain function key is inconvenient to use, the function is hidden, the split screen is not easy to popularize, certain preconditions need to be met, and the split screen can be executed only by application in a recently used list. The screen splitting function in part of mobile phone models only needs to be pulled down from the top of the screen to realize screen splitting, but can be executed only when information is received, and misoperation is easy to occur as the same as other actions needing to pull down menus.

Therefore, the existing operating system can support split screen display, but the convenience of entering split screen is low, the reliability of operation is not high, the split screen cannot be realized according to user-defined individual requirements, and misoperation is easy to occur due to the fact that the action design of canceling the split screen after the split screen is realized. Therefore, there is a need to develop a more convenient and reliable multi-screen entering mode, and also to develop a corresponding multi-screen mode exiting mechanism, so that the user can freely enter and exit the multi-screen mode according to the current application scenario, wherein the exiting action is optimally associated with the action of entering the multi-screen mode, so as to facilitate understanding and memorizing.

Disclosure of the invention

The invention aims to provide a split screen display control method of an intelligent terminal, which enables a function entrance to be shallow and easy to understand, keeps the action exchange part consistent with the action habit of tearing articles by a user daily and is convenient for understanding and memorizing split screen actions.

The invention provides an intelligent terminal which comprises a touch screen, a touch signal processing unit, a central controller and a display unit, and is characterized in that the control method comprises the following steps: s1, a multi-touch judging step, namely judging that the input on the touch screen is a multi-touch signal, if so, executing a step S2; s2, touch track judging, if the touch tracks formed on the touch screen are far away from each other, executing S3; s3, judging screen content, wherein the central controller judges whether the current display content is a screen-separable operation interface, if so, executing the step S4; and S4, executing a screen splitting step, and splitting the current display content into a first split screen and a second split screen for display, wherein a splitting bar is arranged between the first split screen and the second split screen.

If the determination result in the steps S1, S2, and S3 is no, the central controller determines the operation intention of the user according to the touch trajectory of the touch signal and the current display content, and performs other operations.

Wherein the control method may further include: s5, limiting the split screen number, namely, after the step S3 is finished, entering the step S5 and limiting the split screen number, if the current split screen number reaches the preset maximum split screen number designated by the intelligent terminal, stopping executing the step S4, returning to the standby step, and simultaneously controlling the display unit to output prompt information that the split screen number reaches the upper limit by the central controller; and if the current split screen number does not reach the preset maximum split screen number specified by the intelligent terminal, executing the step S4.

The invention also provides a method for further separating one split screen, which comprises the following steps: and sequentially executing the steps S1, S2, S3, S5, and S4 to further separate one of the first split screen and the second split screen into two split screens, wherein the step S3 of the control method and the step of determining the screen content also simultaneously determine whether the touch points are located in the same split screen area, if so, the split screen where the touch points are located is further separated into two split screens, and if not, the central controller determines to perform other operations according to the touch trajectory and the current display content.

The invention provides an intelligent terminal split screen display control method and simultaneously provides a split screen ending process, wherein the split screen ending process comprises the following steps: s21, a multi-touch judging step, namely judging that the input on the touch screen is a multi-touch signal, if so, executing a step S22; s22, touch track judging, if the touch tracks formed on the touch screen are close to each other, executing S23; s23, judging screen content, wherein the central controller judges that the starting point of the touch track is positioned in different screen division areas, if so, executing a step S24; and S24, executing a screen splitting ending step, combining the currently displayed first split screen and the second split screen into a display area, and eliminating the separating bar.

In step S24 in the split screen elimination procedure, the central controller compares the display area ratios of the first split screen and the second split screen, eliminates the split screen with a small display area, and retains the split screen with a large display area.

The invention also provides another second split screen ending process matched with the split screen control process, wherein the split screen ending process comprises the following steps: s31, a single-point touch judging step, namely judging that the input signal on the touch screen is a single-point touch signal, if so, executing a step S32; s32, a touch track judging step, if the touch track formed on the touch screen slides from the first split screen to the second split screen, executing the step S33; s33, touch end point distance judging, if the end point of the touch track exceeds the separation bar by a preset distance D, executing the step S34; and S34, executing a screen splitting ending step, combining the currently displayed first split screen and the second split screen into a display area, and eliminating the separating bar. After the step S34 is executed, the second split screen is retained, and the first split screen is eliminated.

The preset distance D in the second split-screen ending process is larger than or equal to the height of one application icon, so that misoperation in the sliding process of the user is avoided, the user slides into the second split-screen area, and the probability of misjudging the user intention is reduced.

In the split-screen display control method of the intelligent terminal, after the split screen of the display screen is realized, a user can drag any point on the separation bar to adjust the display area proportion of the first split screen and the second split screen.

The technical solution of the present invention will be described in detail with specific examples in conjunction with fig. 1 to 5. The following embodiments may be combined, and details of the same or similar concepts or processes may not be repeated in some embodiments.

The intelligent terminal comprises an intelligent mobile phone, a PAD, a GPS navigator, a personal computer and the like, and has multi-point touch sensing capability, wherein the mobile phone is most widely applied, so the method for controlling the split-screen display of the intelligent terminal is described below by taking the mobile phone as an example. However, other intelligent terminals may also adopt the split-screen display control method defined by the present invention, and are not limited to the application of mobile phones.

Fig. 1 shows a hardware structure of a mobile phone capable of implementing a split-screen display of an intelligent terminal according to the present invention, where the mobile phone includes a touch screen 100 capable of sensing a multi-touch input, where the touch input may be a capacitive or resistive touch screen. Also included are a touch signal processing unit 110, a central controller 120, a display unit 130 and a memory 140. The touch screen is connected to the touch signal processing unit 110 through a wire, the touch signal processing unit 110 is connected to the central controller 120 through a wire, and the central controller 120 outputs a signal to the display unit 130 through a wire. The central controller is also connected to a memory to accomplish the storage of data. The mobile phone of the present invention may further include necessary components such as a wireless communication component, a power management chip, a camera, a microphone, etc., but the split-screen display control method of the present invention may be implemented as long as the digital terminal has the basic hardware structure shown in fig. 1 of the present invention. Wherein the display signal output by the display unit 130 drives the touch screen 100 to display to the user, so the display unit 130 can be integrated with the touch screen 100.

In the operation process of the mobile phone, a user of the mobile phone contacts the touch screen 100 with one or two fingers, and the touch signal processing unit 110 senses coordinates (X, Y) on the screen touched by the fingers, X-axis coordinates (the transverse position of the mobile phone screen), and Y-axis coordinates (the longitudinal direction of the mobile phone screen). When the finger of the user continuously slides on the touch screen, the corresponding touch signal processing unit 110 records a series of touch point coordinates from the initial touch point to form a touch point sliding track, thereby determining the motion posture and track of the hand of the user. The touch signal processed and formed by the touch signal processing unit 110 is transmitted to the controller 120, and the controller 120 determines the control command represented by the touch signal according to the received touch signal and the current signal output by the controller to the display unit 130, that is, the current content displayed on the screen.

Fig. 2 shows a flow chart illustrating an operation flow of the method for controlling split-screen display of the intelligent terminal according to the present invention. The invention comprises the following steps:

s1, a multi-touch determining step, in which a touch signal is first sensed by the touch screen 100, and then the touch signal processing unit 110 determines whether the touch signal includes a multi-touch signal according to the position and trajectory of the touch signal, if so, the next step S2 is performed to further determine, and if not, the controller 120 determines whether the touch signal is a touch command, and performs a corresponding action according to the determination result.

S2, a touch trajectory determination step, in which the touch signal processing unit determines whether the trajectories formed by the multiple touch signals are far away from each other according to the positions and trajectories of the touch signals, if so, the next step S3 is performed to further determine, if not, the controller 120 determines whether the trajectories are other touch commands, and performs corresponding actions according to the determination result.

S3, a step of determining a display interface, in which the controller 120 determines according to the content currently output to the display unit 130, if the output content of the current screen is a main screen interface (i.e. desktop) or a display page of another application capable of performing a split screen operation, the next step S4 is performed to further determine, if not, the controller 120 determines whether the current screen is another touch instruction, and performs a corresponding action according to the determination result.

Other applications in which the screen splitting can be performed in step S3 include: the interface comprises a short message interface, a WeChat part interface, a browser interface and the like, and the interfaces do not comprise an instruction for amplifying contents through two touch tracks which are far away from each other, so that the interface does not conflict with the screen splitting instruction defined by the invention. On the contrary, for browsing web page content, photo content and the like supporting displaying content amplification instructions, because the split screen action and the content amplification action instructions set by the invention are two touch tracks far away from each other, a conflict occurs. In summary, the controller 120 needs to determine the currently displayed content, and if the touch instruction supported by the currently opened application is an application that does not conflict with the touch trajectory away from each other, the currently opened application is considered to be a split-screen instruction, and if the currently opened application is a conflicting application, the currently opened application is defaulted to the application that wants to enlarge the currently displayed content or an action specified by another currently displayed application. In addition, the main screen interface also comprises a second page and a third page of the desktop which enter through turning over the screen besides the desktop home page, and the main screen interface can be considered as the screen-separable interface defined by the invention as long as the mobile phone desktop displayed on the front screen or the display interface of the application does not support the touch tracks which are mutually far away.

And S4, judging the upper limit of the split screen number, wherein the central controller presets the upper limit of the split screen according to the parameters of the size, proportion, resolution ratio and the like of the screen of the mobile phone, for example, a rectangular mobile phone touch screen is divided into an upper split screen and a lower split screen by default, and if the size of the screen is large enough, or the mobile phone is in a horizontal state, the left split screen and the right split screen can be supported. The maximum split screen number is provided according to the screen size of the intelligent terminal, for example, a screen of 9 inches can support 4 split screens at maximum. If the number of the split screens is too large, the content which can be displayed on each split screen on the display frequency is very small, and if the graphic size is zoomed, the displayed content is distorted and distorted, and cannot be easily read by a user. Therefore, if the current screen display is already in the split screen mode, the split screen command is received again through the determination steps described in S1-S3, the split screen command of the user will not be executed due to the limitation of the upper limit of the split screen, and the controller 120 can control the display unit to output the display in which the split screen exceeds the upper limit, so as to remind the user and return to the standby state. If the screen splitting command is received through the judgment steps described in the above steps S1-S3 and the number of split screens has not reached the upper limit, the next step S5 is proceeded to further execute the screen splitting command,

and S5, executing a screen splitting instruction, and automatically splitting the screen into a first split screen and a second split screen according to the size and the proportion of the screen. The first and second sub-screens simultaneously display the current desktop content with a separator bar 30 disposed between the first and second sub-screens.

After entering the split-screen display mode of S5, the user may open different mobile phone applications from different split screens as needed, for example, the second split screen located below may select to open a first type of application, for example, an application that needs to be frequently opened and processed or replied, such as a short message, a WeChat, an email, etc.; the first split screen positioned above the screen can be applied to the second type of application, such as an application needing long-time attention, such as video streaming media playing, an electronic book needing long-time reading, a webpage and a game interface. Therefore, the two different types of applications can be independently displayed in the two split screens without mutual interference, and the process that the other display window is opened after the current display window is closed does not exist. For example, when the user receives the WeChat prompt in the process of watching the video streaming media, the user can directly click to enter the WeChat application from the second split screen under the condition of keeping the playing content of the first split screen, and information reading and corresponding reply are carried out. The content displayed in the first split screen is that data is filled in a website needing data input, a search engine is opened in the second split screen for inquiry or other people are inquired to know information in the second split screen, or social software is used for inquiring other people in the second split screen, the required information content is obtained and then is directly filled in the webpage of the first split screen, the operation process can avoid the situation that the webpage data is re-read due to frequent switching of the first split screen, part of the content needs to be repeatedly filled in, and part of the webpage can be accessed by providing the verification code, so that repeated verification code filling can be further avoided. The content of the first split screen and the content of the second split screen can be selected by the user according to respective use habits and convenience, so that diversified requirements of the user can be met.

In the split-screen display mode, the user can autonomously adjust the display ratio of the first split screen and the second split screen, for example, the first split screen displays 30% of the area, and the second split screen displays 70% of the area. The specific operation can be realized by the following method: when the touch screen detects that the initial touch point is located on the division bar 30 between the first split screen and the second split screen, and the touch signal processing unit 110 detects that the subsequent touch movement track moves upwards, it is considered that the user wants to move the division bar 30 upwards, the display areas of the corresponding first split screen and the second split screen also change correspondingly, the display area of the first split screen becomes smaller, and the display area of the second split screen becomes larger. Similarly, when the touch signal processing unit 110 detects that the subsequent motion trajectory moves downward, the division bar 30 moves downward, the display area of the second split screen becomes smaller, and the display area of the first split screen becomes larger. Preferably, the adjustment of the split screen area has an upper limit, for example, the display area of the first split screen occupies 10% to 90% of the whole screen, and if the display area of the first split screen is smaller than 10%, because the display area is too small, the user cannot effectively identify the content displayed in the first split screen, and the split screen display will lose meaning. And if the display area of the first split screen is too small, the fingers of the user can not quickly and accurately click to enter the first split screen area, and the subsequent operation of finishing the split screen can be influenced. The display area of the same second split screen also needs to be adjusted in the range of 90% -10%.

In the invention, in addition to the up-and-down screen splitting as shown in fig. 3, the second split screen can be further split into more split screen areas. As shown in fig. 4, when the touch screen 100 and the touch signal processing unit 110 detect that two initial touch points P11, P12 of the user are located in the same split screen, i.e., the second split screen, and then the touch trajectory extends to two sides for a sufficient distance, the determination according to the steps S1-S5 described in the embodiment shown in fig. 2 can determine that the user is to separate the second split screen into the second split screen and the third split screen. Meanwhile, a new separation bar 32 is generated between the second split screen and the third split screen, the display area proportion of the second split screen and the third split screen can be adjusted by clicking the separation bar 32 and moving left and right, and the optimal display area proportion is adjustable in a range of 10% -90%. The respective proportions of the first, second and third component screens can be precisely adjusted by jointly adjusting the positions of the two separating

strips

30, 32, so that the respective areas meet the requirements of displaying contents in the areas. In the same way, the first screen division area can be further divided to form another two screen division areas, so that the multi-directional complex screen division can be carried out as long as the area size of the display screen allows, and the screen division method can meet the customized requirements of large-area high-resolution display screens.

The split screen method provided by the invention can conveniently and simultaneously display the contents of a plurality of different applications, but when the maximum area is required to display the content of one application, a convenient and quick method is also needed to end the current split screen display mode. The invention provides a convenient, quick and reliable method for ending the current split screen mode besides a method for conveniently entering and maintaining the split screen mode, and the method can meet the variable requirements of users at different moments and improve the utilization rate of split screen operation.

Fig. 5a shows a first embodiment of the method for turning off the split screen display according to the present invention. The touch action judging step for closing the split screen comprises the following steps:

s21, a multi-touch determining step, in which a touch signal is first sensed by the touch screen, and then the touch signal processing unit 120 determines whether the touch signal includes a multi-touch signal according to the position and trajectory of the touch signal, if so, the next step S22 is performed to further determine, and if not, the controller 120 determines whether the touch signal is a touch command, and performs a corresponding action according to the determination result.

S22, determining the initial position of the touch track, if the initial positions P21 and P22 of the touch point are located in two different screen areas, then the step S23 is performed to further determine, if not, the controller 120 determines whether the touch point is other touch commands, and corresponding actions are performed according to the determination result.

S23, a touch trajectory determination step, in which the touch points of the two fingers approach the separator to form a closing action according to the touch trajectory determination of the touch signal processing unit 120, and then step S24 is performed; if not, the controller 120 determines whether the touch command is another touch command, and performs a corresponding action according to the determination result.

S24 turns off one of the two divided screens designated by the touch points P21, P22, and one of the divided screens is retained. The selection of the reserved split screen can be judged according to the display area of the split screen, for example, if the area of the first split screen occupies 30% and the area of the second split screen occupies 70%, when it is judged that the user needs to close the split screen according to the touch action trajectory judgment steps S21-S23, the second split screen with larger reserved area is defaulted, and the first split screen display is closed.

Fig. 5b is a schematic diagram of a user touch trajectory corresponding to the execution flow shown in fig. 5a, and it can be seen that a user performs an action opposite to entering the split-screen display mode, and a pinch gesture is performed to end a group of split screens.

Fig. 6a and 6b show a second embodiment of the method for turning off the split screen display according to the present invention. The touch action judging step of turning off the split screen can comprise the following steps:

s31, a single-point touch determining step, in which a touch signal is first sensed by the touch screen, and then the touch signal processing unit 120 determines whether the touch signal is single-point touch according to the position and trajectory of the touch signal, if so, the next step S32 is performed to further determine, otherwise, the controller 120 determines whether the touch signal is other touch command, and performs corresponding action according to the determination result.

S32, touch trajectory determination, if the initial position P31 of the touch point is in one screen division area and the touch film point slides to another screen division area, then step S33 is performed to further determine if the touch point is not the other touch command, and corresponding action is performed according to the determination result.

S33, a touch end point determining step, in which the tail end of the touch trajectory passes through the separator bar 34 by a certain distance according to the touch trajectory determination of the touch signal processing unit 120, for example, if the distance from the tail end to the separator bar reaches D as shown in the figure, the process goes to step S34; if not, the controller 120 determines whether the touch command is another touch command, and performs a corresponding action according to the determination result.

And S34, finishing the split screen display execution step, closing the split screen where the initial touch point P31 is located, namely the first split screen, reserving the second split screen, and eliminating the division bar 34.

The distance D for the tail end of the touch trajectory to cross the barrier bar is set to avoid a malfunction, for example, when the user slides down in the first split screen, the user does not want to close the current split screen because the user moves too much to cross the separation line 34. Therefore, the distance D can be set according to the action habits of the user, the preferred height can be the height of an APP icon, and most users cannot cross the line too far even crossing the separating bar, so that most misoperation can be avoided, and the screen separating area which the users want to close can be guaranteed to be closed.

The method can complete the split screen setting in advance and keep the split screen display state when the emergent moment needing multi-screen display is not met at ordinary times, and open the second application display interface from the other split screen under the condition that the current display content can be kept when two application contents need to be displayed simultaneously, so that the method does not need to open the second split screen temporarily when meeting the emergent condition like the prior art, and the convenience is not enough if too many action instructions for opening the second split screen are too complex, and the user can not use the method if the action instructions are difficult to master; if the action is simple and convenient (such as the top slides downwards), although the convenience performance is met, the action is easy to collide with other action instructions, misoperation is caused, the operation has the prerequisite technical conditions that a plurality of applications run simultaneously, the screen splitting operation cannot be triggered when the technical conditions are not met, and the screen splitting operation is considered to have a problem in effectiveness if the prerequisite conditions are not known in the using process of a general user, so that the use is abandoned. The invention can adopt a command known by a user to carry out the screen splitting operation under the condition of no prerequisite, so that the misoperation is not easy to occur, and the stable execution of the screen splitting operation can be ensured because of no prerequisite.

The invention judges the actions made by the user through the steps of comprehensively judging multi-point touch, mutually separating touch tracks, and the like under the screen-separable operation display interfaces such as a desktop and the like, enters a screen-separable display state, and further can adjust the area sizes of different screen-separable areas by dragging the separating strips after screen separation. And one of the screen division areas can be closed when the user executes the action of kneading the different screen division areas through the multi-point touch sensing. The two actions set by the invention are common actions in the existing mobile phone control, the user can be skillfully used, but the screen splitting operation can be realized by matching with the judgment of the screen content (the currently displayed screen splitting operation interface), so that the method is simple, the action requirement is strict, and the misoperation can be avoided. Meanwhile, the action setting of closing the split screen is opposite to the action of the split screen display mode, so that the user can understand and memorize conveniently, the mobile phone user can conveniently and quickly remember the entering and exiting actions of the split screen operation through the operation combination, and misoperation can be avoided.
