Detailed Description
To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
Referring to fig. 1 to 3, the present embodiment provides a multi-screen based control method for a device having a first split screen and a second split screen. The first screen splitting device comprises a main processor and an operating system and can acquire the operation of a user. The first screen splitting device also comprises a first split screen, i.e. a first screen, for displaying image content. The second split screen may be a display screen connected to the hardware display interface of the first split screen device (including wired or wireless connections). The method of the invention comprises the following steps: step S101, a screen rotation trigger signal in equipment where the first split screen is located is obtained. The screen rotation trigger signal is a signal indicating that screen rotation is to be performed, and may be set to perform rotation trigger only for the second split screen or to perform rotation trigger for both the first split screen and the second split screen. And S102, modifying the display direction and width and height of the display interface of the second split screen according to the direction of the screen rotation trigger signal, and redrawing the display interface of the second split screen. The display direction of the second split screen may be the same as the direction of the rotation trigger signal, and if the rotation trigger signal is a horizontal signal, the display interface of the second split screen is modified to be in the horizontal direction. The width and height of the display interface can be determined according to the size of the second split screen display. Therefore, the modification of the display interface of the second split screen can be completed through the first split screen device, and the fact that the rotation angle of the second split screen needs to be actually adjusted is avoided. The number of the second sub-screens can be multiple, so that the display directions of other multiple screens can be flexibly controlled, the actual angles of other screens do not need to be adjusted, the operation flexibility is enhanced, and the user experience is improved.
In the present invention, the width and height of the second split screen may be determined by the device of the first split screen. In some embodiments, since the second split screen is horizontally disposed, when the displayed interface is an interface with a narrower width, the width of the display interface before modification can be used as the modified height, and for a place on the display screen where no picture is displayed, a black border can be used for filling.
In some embodiments, if the screen rotation trigger signal is for only the first split screen, the present invention further comprises the steps of: and keeping the display direction of the display interface of the second split screen unchanged. Namely, the display interface condition of the second split screen is not changed.
When the mouse is applied, the first split screen is generally fixed and different, the display direction of the first split screen can be changed, and the mouse can be changed along with the modification of the display direction. If the original horizontal display is performed, the mouse operation is up-down movement, the mouse also moves up-down on the display screen, and after the display direction is changed to be vertical, the mouse moves up-down, the mouse moves left-right on the display screen, so that the user operation is influenced. In order to solve the problem, the invention further comprises the steps of: acquiring an offset value of the mouse associated with the second split screen in the X direction and an offset value of the mouse associated with the second split screen in the Y direction; judging whether the display direction of the display interface of the second split screen is a preset rotation direction or not; if the direction is the preset rotation direction, the deviation value in the X direction and the deviation value in the Y direction are converted, and the mouse pointer of the second split screen responds to the converted deviation value; otherwise, the mouse pointer of the second split screen directly responds to the offset value of the mouse. The conversion is to exchange the X direction (left-right direction) and the Y direction (up-down direction) so that the pointer on the mouse moves in the same way as the original operation mode before rotation after the screen rotates the display direction, thereby not affecting the actual operation and correspondence of the mouse. In some embodiments, the display direction of the mouse pointer may also be kept unchanged when the screen is rotated, that is, the display direction of the mouse pointer is unchanged relative to the hardware screen (non-display screen) of the display screen, as shown in fig. 3, so that the display effect is more friendly.
The split screen of the invention can be different parts corresponding to one system screen, such as the extended display of the existing windows system. Or the system of the present invention may be an android system. The first split screen and the second split screen can be a main screen and an auxiliary screen of the android system respectively. The main screen and the auxiliary screen are connected with different LCD controllers of the android system, and the android system respectively controls the display of the different LCD controllers. The main screen and the auxiliary screen of the android system are two independent screens, correspond to different LCD controllers, can perform independent display and independent operation, and the applications in different screens can only be displayed on the corresponding screens when being created. Therefore, independent display of different split screens can be performed, and independent operation and display of different applications can be realized.
In some embodiments with multiple mice, the invention can further realize the control of different mice with different split screens. For the android system, after a first mouse is inserted, when a second mouse is inserted, the system needs to acquire the device ID of the second mouse; and reserving the first mouse device service and newly creating a second mouse device service, and binding the device ID of the second mouse to the second mouse device service, wherein the second mouse device service comprises a corresponding second mouse pointer, and the second mouse device service acquires corresponding second mouse operation information from the second mouse device ID and responds. Binding the first mouse equipment service with a first split screen, and limiting first mouse operation information responded by the first mouse equipment service in the first split screen; when the second mouse device service is created, the second mouse device service is bound with the second split screen, and second mouse operation information responded by the second mouse device service is limited in the second split screen. Therefore, different split screens can correspond to different mice, the movement and operation of the mice are in the split screens, and different operations of a plurality of split screens and a plurality of mice in one system can be realized. Under the condition of the android main and auxiliary screens, the system is equivalent to a system (namely a single system), but two sets of independent mouse control and display are provided, so that two independent operations of one system are realized, different operation requirements are met, and the hardware investment cost can be reduced. When the number of the split screens is more than two, more hardware cost can be reduced.
The invention does not limit the type of the screen rotation trigger signal, and can be a gravity sensor signal, a gesture signal or a key signal, as shown in fig. 2. Wherein the gravity sensor signal may be a signal of a change in gravity direction; the gesture signal can be a gesture signal analyzed after the camera acquires the gesture image, and can also be a sliding signal touched by the touch screen; the key signal may be a physical key or a screen virtual key signal.
The invention provides a multi-screen-based control system, which comprises a first split-screen device and a second split-screen device, wherein the first split-screen device comprises a memory and a processor, a computer program is stored in the memory, and the computer program realizes the steps of the method according to any embodiment of the invention when being executed by the processor. After the signal of the sensor in the first sub-screen is controlled, the display directions of other screens can be flexibly controlled, the actual angles of the other screens do not need to be adjusted, the operation flexibility is enhanced, and the user experience is improved.
It should be noted that, although the above embodiments have been described herein, the invention is not limited thereto. Therefore, based on the innovative concepts of the present invention, the technical solutions of the present invention can be directly or indirectly applied to other related technical fields by making changes and modifications to the embodiments described herein, or by using equivalent structures or equivalent processes performed in the content of the present specification and the attached drawings, which are included in the scope of the present invention.
