[0080] Exemplary embodiments are described in detail herein, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numerals in different drawings represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present disclosure.

[0081] The present disclosure provides a split-screen control method for use in a scenario where a terminal has a function of responding to control instructions triggered by a stylus pen, wherein the terminal may be a tablet computer.

[0082] In related technologies, styluses are paired with physical buttons. Depending on the configuration, the physical buttons can perform different functions. For example, some styluses are equipped with Page Up and Page Down buttons that can perform page-turning operations, allowing users to conveniently control the terminal with the stylus. However, physical buttons can only perform functions similar to Page Up and Page Down, which are relatively simple.

[0083] Split-screen technology allows users to enter split-screen mode by swiping two fingers from the top of the device screen to a specified location. However, relying solely on user finger operations can lead to accidental touches. For example, when using some applications, users may use two fingers, resulting in a split-screen display on the device, which is not what they expected. This triggers commands that do not match user expectations, resulting in a poor user experience when using applications.

[0084] In view of this, an embodiment of the present disclosure provides a split-screen control method, which is applied to a terminal with the function of responding to control instructions triggered by a stylus. In response to receiving a control instruction triggered by a stylus, if the control instruction is a control instruction for triggering a split screen, the terminal creates a window for intercepting non-stylus touch events, and the window can also detect stylus touch events. The terminal determines the split-screen position of the terminal based on the touch event of the stylus detected by the window, and splits the terminal. The stylus triggers the terminal's control instruction to trigger the split screen, which can greatly reduce accidental touches and reduce the operations of triggering the split screen, thereby improving the user experience.

[0085] Figure 1 FIG. 1 is a flow chart of a split screen control method according to an exemplary embodiment. Figure 1 As shown, the method is applied to a terminal, and the terminal has a function of responding to control instructions triggered by a stylus pen, and includes the following steps.

[0086] In step S11 , in response to receiving a control instruction triggered by a stylus pen and determining that the control instruction is a control instruction for triggering screen splitting, a window is created.

[0087] In step S12, the split screen position of the terminal is determined based on the touch event of the stylus pen detected by the window.

[0088] In step S13, the terminal is split into two screens based on the split screen positions.

[0089] The window is used to intercept non-stylus pen touch events and detect stylus pen touch events.

[0090] In the disclosed embodiment, the terminal determines whether a touch command from a stylus pen triggers a split-screen control command. If so, a window is created to intercept non-stylus pen touch events (MotionEvents) and detect stylus pen touch events. Based on the stylus pen touch events detected by this window, the terminal determines the split-screen position for the terminal, and the terminal splits the screen at that position.

[0091] In the disclosed embodiments, the control command triggered by the stylus can be a control command triggered by any preset key of the stylus, for example, a control command triggered by long pressing the Page Down key or Page Up key of the stylus. The window can be a system-level window created by WindowsManger.addView.

[0092] The split-screen control method provided by the disclosed embodiments adds a window at the system level of the terminal to intercept non-stylus touch events and detect stylus touch events. Compared to triggering split-screen through user gestures, this avoids adding a global gesture listener to the system, which would result in frequent calls to system resources. This reduces the consumption of system resources and avoids accidental touches by users when triggering split-screen control commands through a stylus.

[0093] The split-screen control method provided by the embodiment of the present disclosure determines the split-screen position of the terminal through a stylus, and when the stylus triggers the control instruction of the split-screen, it can be triggered by the button of the stylus.

[0094] Figure 2 A flow chart of a method for determining that a control instruction is a control instruction that triggers split screen is shown according to an exemplary embodiment. Figure 2 As shown, the stylus includes a button, and determining that the control instruction is a control instruction for triggering split screen includes the following steps.

[0095] In step S21 , in response to detecting a control instruction indicating that a key is pressed, the control instruction indicating that the key is pressed is cached, and reporting of the control instruction is suppressed.

[0096] In step S22, the duration of the button being pressed is monitored.

[0097] In step S23, if the duration is greater than the preset duration, it is determined that a control instruction of a key being long pressed is detected, and the control instruction of the key being long pressed is determined as a control instruction for triggering split screen.

[0098] In the disclosed embodiment, the stylus includes a button. When the terminal detects that the stylus has pressed the button, the control instruction sent by the button is cached and the control instruction is suppressed from being reported. The control instruction of the stylus button is continuously detected, and the duration of the stylus button being pressed is monitored. If the duration is greater than the preset duration, the control instruction of the stylus button being long pressed is determined, and the control instruction of the button being long pressed is determined as the control instruction for triggering split screen. A window is added to the terminal system to determine the position of the terminal split screen, and the original control instruction of this button is deleted, so that the terminal executes the split screen control instruction and does not execute the original control instruction. If the duration is less than the preset duration, it is determined that the stylus button executes the original control instruction, and the terminal executes the control of the original control instruction.

[0099] In an exemplary embodiment, taking the case where a stylus is long-pressed on the Page Down button to trigger a split-screen control instruction, with a preset duration of 300ms (time unit, milliseconds) as an example, if a control instruction sent by Page Down is detected, the Page Down instruction is cached, and the Page Down instruction is suppressed from being reported. The duration of the Page Down press is monitored. If it exceeds 300ms, it is determined that the Page Down button triggered a long press to execute the split-screen instruction, and the Page Down instruction is deleted, and the page down instruction is not executed. If it is detected that the button is pressed for less than 300ms, the Page Down instruction is triggered, and the terminal controls the page down.

[0100] The split-screen control method provided by the embodiment of the present disclosure can monitor the duration of time the stylus key is pressed, thereby distinguishing between long press and click events of the stylus key, preventing command conflicts, and thus realizing different control commands of the stylus key on the terminal, thereby improving the user experience.

[0101] In the split-screen control method provided by the embodiment of the present disclosure, a long press of a stylus button is determined to trigger the split-screen control of the terminal, and the split-screen position of the terminal also needs to be determined.

[0102] Figure 3 FIG. 1 is a flow chart showing a method for determining a split screen position of a terminal according to an exemplary embodiment. Figure 3 As shown, determining the split screen position of the terminal based on the touch event of the stylus detected by the window includes the following steps.

[0103] In step S31 , in response to detecting a touch event of the stylus based on the window, a touch reporting point corresponding to the touch event is recorded.

[0104] In step S32, the split screen position of the terminal is determined based on the touch point reporting.

[0105] In the disclosed embodiment, when a window detects a touch event from a stylus and determines it is a split-screen control command, the touch reporting point corresponding to the touch event is recorded. The reporting point of the split-screen control triggered by the stylus is used as the starting reporting point and is recorded until the stylus is lifted from the terminal screen or the stylus triggers the end of the touch event. During this period, all reporting points of the stylus are reporting points corresponding to the touch event. Based on the touch reporting point, the terminal's split-screen position is determined.

[0106] In another exemplary embodiment, the terminal records the touch reporting point corresponding to the touch event, and directly determines the split screen position according to the position of the touch reporting point.

[0107] After the window is created, if a user's gesture command is detected, the gesture command will not be processed.

[0108] Through the split-screen control method provided by the embodiment of the present disclosure, the user can control the position of the stylus to determine the split-screen position of the terminal, so that the split-screen position of the terminal meets the user's needs and improves the user experience.

[0109] In the split-screen control method provided in the embodiment of the present disclosure, the split-screen position of the terminal can be determined based on the touch point reporting. In one implementation, the stylus slides on the terminal screen to form a sliding track to determine the split-screen position of the terminal.

[0110] Figure 4 FIG. 1 is a flow chart showing a method for determining a split screen position of a terminal according to an exemplary embodiment. Figure 4 As shown, based on the touch reporting point, determining the split screen position of the terminal includes the following steps.

[0111] In step S41 , in response to the touch event being a sliding operation event, all touch reporting points from the start of the touch reporting point to the detection of the end of the touch reporting point are recorded.

[0112] In step S42, based on the recorded touch points, the sliding trajectory of the stylus on the terminal is fitted into a straight line.

[0113] In step S43, the position of the straight line is determined as the split-screen position of the terminal.

[0114] In the disclosed embodiment, if a stylus is detected sliding across the terminal screen, the touch event is determined to be a sliding operation event. The touch reporting point that triggered the touch event is recorded as the starting touch reporting point until the ending touch reporting point is detected. During this period, all points passed by the stylus are recorded as touch reporting points. The touch reporting points are fitted to form the sliding trajectory of the stylus on the terminal, and the fitting result is a straight line. The position of the straight line is determined as the terminal's split-screen position, and the terminal executes the split-screen instruction based on the split-screen position.

[0115] The termination touch reporting point is determined by a termination touch instruction. The termination touch instruction may be that the touch pen is detected to be lifted up on the terminal, or a key of the touch pen is no longer in a pressed state, and the termination touch reporting point is considered to be detected.

[0116] Through the split-screen control method provided by the embodiments of the present disclosure, the user can slide the stylus on the terminal to determine the position of the terminal split screen. Thus, the user can determine the split screen position according to their needs, improving the user experience and efficiency.

[0117] The split-screen control method provided by the embodiment of the present disclosure can determine the split-screen position of the terminal according to the sliding trajectory of the stylus on the terminal. The sliding trajectory needs to be fitted, and the fitting result is a straight line.

[0118] Figure 5 FIG. 1 is a flow chart showing a method for fitting a sliding track of a stylus pen on a terminal into a straight line according to an exemplary embodiment. Figure 5 As shown, based on the recorded touch points, fitting the sliding trajectory of the stylus on the terminal into a straight line includes the following steps.

[0119] In step S51, the touch points that meet the fitting conditions are screened from the recorded touch points.

[0120] In step S52, based on the touch points that meet the fitting conditions, the sliding trajectory of the stylus pen on the terminal is fitted into a straight line.

[0121] In the embodiment of the present disclosure, the touch point reporting that meets the fitting conditions includes the absolute value of the difference between the first target coordinates and the first target of the starting touch point reporting being less than the threshold, and the second target coordinates and the second coordinates of the starting touch point satisfying an increasing or decreasing change relationship.

[0122] The first target coordinate is the horizontal coordinate, and the second target coordinate is the vertical coordinate, or the first target coordinate is the vertical coordinate, and the second target coordinate is the horizontal coordinate.

[0123] Among them, the role of the threshold is to prevent jitter, and the fitting condition can fit the touch points into a straight line, and the terminal splits the screen according to the fitted straight line.

[0124] In an exemplary embodiment, taking the touch reporting point as Point (x, y), the upper left corner of the screen as the coordinate origin (0, 0), the threshold as 200 pixels, and x as 1000 pixels as an example, the note reporting point Point (x, y) where the stylus passes on the terminal screen is recorded. When the stylus is lifted from the terminal screen or the stylus button is lifted, the sliding trajectory of the stylus is calculated. The touch reporting point that triggers the touch event is used as the starting touch reporting point, and the starting touch reporting point x is determined to be 1000 pixels and y is 0 pixels. The recorded touch reporting points are judged, and the ones with increasing y values ​​and the absolute value of the difference between the x coordinate of the corresponding pixel touch reporting point and 1000 is selected to be less than 200 pixels. All touch reporting points that meet the fitting conditions are screened out and fitted. The fitting result is a straight line.

[0125] Through the split-screen control method provided by the embodiment of the present disclosure, the sliding trajectory of the stylus is fitted to prevent jitter, the terminal split-screen position is determined, and the accuracy of the terminal split-screen position is improved.

[0126] In the embodiment of the present disclosure, the starting touch reporting point is a reporting point within a set distance from the edge of the terminal screen.

[0127] In an exemplary embodiment, taking the set distance as 50 pixels as an example, when the stylus is pressed on the terminal screen (MotionEvent.Action_Down), it is determined that the touch point is within 50 pixels of the screen edge, and the sliding trajectory of the stylus is detected and calculated.

[0128] The split-screen control method provided by the embodiments of the present disclosure can accurately detect the sliding trajectory of the stylus pen.

[0129] Figure 6 FIG. 1 is a flow chart showing a method for determining a split screen position of a terminal according to an exemplary embodiment. Figure 6 As shown, based on the touch reporting point, determining the split screen position of the terminal includes the following steps.

[0130] In step S61 , in response to the touch event being a touch operation, a current touch area corresponding to the touch reporting point is determined.

[0131] In step S62, based on the relationship between the touch area and the split-screen position, the split-screen position corresponding to the current touch area is determined.

[0132] In the disclosed embodiment, if a touch event is detected but no stylus sliding track is present, the touch event is determined to be a touch operation, and the current touch area corresponding to the touch point is determined. Based on the relationship between the touch area and the split-screen position, the split-screen position corresponding to the current touch area is determined.

[0133] The relationship between the touch area and the split-screen position can be that the terminal screen is divided into four areas: upper, lower, left, and right. The touch reporting point is determined to be located in the upper left, lower left, upper right, and lower right areas based on the coordinates of the touch reporting point. If the touch area where the touch reporting point is located is the upper left or upper right, the left-right split screen / upper-lower split screen is performed. If the touch area where the touch reporting point is located is the lower left or lower right, the upper-lower split screen / left-right split screen is performed.

[0134] A one-to-one correspondence between the touch area and the split-screen position is preset. In the embodiment of the present disclosure, a one-to-one correspondence between any touch area and the split-screen position can be achieved.

[0135] The split-screen control method provided by the embodiment of the present disclosure can determine the split-screen area according to the touch points reported by the stylus on the terminal screen, thereby splitting the screen and improving the convenience of the user's split-screen operation.

[0136] In the embodiment of the present disclosure, the split screen position includes a split screen position for top-bottom split screen and / or a split screen position for left-right split screen.

[0137] In the embodiment of the present disclosure, the function corresponding to the control instruction of prohibiting the key from being pressed is triggered.

[0138] In the disclosed embodiment, in response to detecting a control instruction that does not trigger screen splitting, the window is removed, allowing the terminal to execute the control instruction originally triggered by the stylus without conflicting with the original control instruction, while reducing global system event monitoring, lowering power consumption, and improving system stability.

[0139] In the disclosed embodiment, an animation that matches the split-screen position is displayed according to the split-screen position, thereby improving the user experience.

[0140] Figure 7 FIG. 1 is a flow chart of a split screen control method according to an exemplary embodiment. Figure 7 As shown, it is determined whether the stylus button is pressed. If so, a window is added and a touch event is detected. If not, the split-screen control is ended. It is determined whether the stylus is sliding on the terminal screen. If so, and the starting touch reporting point is a reporting point within a set distance from the edge of the terminal screen, the touch reporting point of this touch event is recorded, filtered, and it is determined that the filtered touch reporting points all meet the fitting conditions, and fitting is performed. The straight line obtained by fitting is used as the position of the split screen, and the terminal splits the screen according to the split screen position. The split-screen control method provided by the embodiment of the present disclosure can reduce false touches, and adds animation effects, improves user experience, reduces global system monitoring events (such as gesture monitoring), reduces system power consumption, and thus improves system stability.

[0141] Figure 8A 、 8B8C is a schematic diagram showing a split screen control method according to an exemplary embodiment. Figure 8A As shown, the stylus triggers the touch event of the terminal and records the current touch reporting point as the starting touch reporting point. Figure 8B As shown, taking the stylus pen sliding left and right on the terminal as an example, the stylus pen performs a sliding operation event on the terminal screen, triggering the terminal's split-screen control. According to the sliding track of the stylus pen on the terminal screen, the split-screen position is generated, determined as the upper and lower split screens, and an animation matching the split-screen position is displayed at the split-screen position. Figure 8C , which is a schematic diagram of the terminal splitting the screen into upper and lower parts according to the sliding trajectory of the stylus.

[0142] Among them, it can be understood that when the stylus is slid on the terminal screen, the split screen position of the terminal is the sliding trajectory of the stylus, and the screen can be split using any touch point on the terminal screen that meets the fitting conditions as the starting touch point.
