Further, "connected" or "coupled" as used herein may include wirelessly connected or wirelessly coupled. As used herein, the term "and/or" includes all or any element and all combinations of one or more of the associated listed items.
It will be understood by those skilled in the art that, unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the prior art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
As will be appreciated by those skilled in the art, a "terminal" as used herein includes both devices having a wireless signal receiver, which are devices having only a wireless signal receiver without transmit capability, and devices having receive and transmit hardware, which have devices having receive and transmit hardware capable of two-way communication over a two-way communication link. Such a device may include: a cellular or other communication device having a single line display or a multi-line display or a cellular or other communication device without a multi-line display; PCS (Personal Communications Service), which may combine voice, data processing, facsimile and/or data communication capabilities; a PDA (Personal Digital Assistant), which may include a radio frequency receiver, a pager, internet/intranet access, a web browser, a notepad, a calendar and/or a GPS (Global Positioning System) receiver; a conventional laptop and/or palmtop computer or other device having and/or including a radio frequency receiver. As used herein, a "terminal" or "terminal device" may be portable, transportable, installed in a vehicle (aeronautical, maritime, and/or land-based), or situated and/or configured to operate locally and/or in a distributed fashion at any other location(s) on earth and/or in space.

The inventor of the present invention also finds that the existing display output method of the operating system generally includes: a display synthesis module, such as a surface flag module, is further arranged on the upper layer of the kernel in the Android system; the SurfaceFlinger module synthesizes contents which need to be displayed, such as an application window, wallpaper, a status bar and the like which run in an operating system, and outputs the synthesized contents to be displayed to a kernel, and the synthesized contents are displayed by being driven by display hardware. However, according to the input/output method of the existing operating system, when both container systems need to occupy the display output device (including the screen) for display output, it is likely that the content of one container system is displayed on the screen for a while, and the content of the other container system is displayed for a while, which causes confusion of the displayed content, brings great trouble to the user in performing human-computer interaction with the terminal device, and seriously affects the user experience.
The inventors of the present invention considered that a function of recognizing the operation state of each container system may be added to the terminal device. According to the operation state of each container system, the container system in a certain operation state (for example, in the foreground) can perform display output and respond to the input event, and at the moment, other container systems cannot perform display output and cannot respond to the input event.
Based on the above considerations, the inventors of the present invention have provided two improved concepts. Firstly, detecting respective running states by each container system; and secondly, detecting the running state of each container system by a kernel outside each container system. The first and second concepts correspond to the first and second embodiments of the present invention, respectively.
Example one
A schematic frame diagram of an internal structure of a terminal device in the first embodiment of the present invention is shown in fig. 1, and includes: more than two container systems, a kernel, display hardware, and input hardware.
The container system in the present invention (including embodiments one and two) is an operating system provided in a container created by the Linux container virtualization technology. The operating system may be a Linux operating system or a Unix operating system in the conventional sense, an Android system, an Ubuntu system, and the like derived from the Linux operating system, or a Windows system based on a Windows platform, and the like. In fact, the container system of the present invention is not limited to the aforementioned exemplary operating systems, and may cover all operating systems capable of operating in a container. For convenience of description, the technical solution of the present invention is described below by taking an Android system as a container system as an example.
The container system of the first embodiment of the present invention includes: the device comprises a display service module and an input service module. Preferably, the display service module may be improved on the basis of a conventional surfefinger (appearance thrower) module. The input service module can be improved on the basis of the traditional input module. The display service module and the input service module interact with a plurality of applications in the container system, which are also called APPs (applications). Further, the solid line in fig. 1 represents data transmission (one kind of data interaction), and the dotted line represents data non-transmission (i.e., data interaction is not performed).
Preferably, for convenience of description, the container system located at the front stage is referred to as a first container system in the present invention; container systems located in the background are collectively referred to as other container systems.
The kernel in the first embodiment of the present invention may be a kernel. Preferably, the kernel may be a kernel of one of the plurality of versions. The kernel comprises a display module and an input module.
In the first embodiment of the present invention, the display service module and the input service module in the container system interact with the display module and the input module in the kernel, respectively.
The display hardware and the input hardware in the first embodiment of the invention interact with the display module and the input module in Kernel respectively.
Fig. 2 is a schematic flow chart of a multisystem-based input/output method according to a first embodiment of the present invention, which includes the following steps:
s201: and after receiving the input event, the input module in the kernel respectively sends the input event to more than two container systems in the equipment.
And the input module in the kernel packages input information of the user into an input event after receiving input operation of the user through input hardware in the terminal equipment.
And the input module in the kernel sends the packaged input event to an input service module in a first container system in a foreground and an input service module in other container systems in a background in the terminal equipment respectively.
S202: after receiving the input event, the input service module in the first container system sends the input event to the corresponding application if detecting that the first container system is in the foreground.
After an input service module in the first container system receives an input event, the operating state of the first container system where the input service module is located is detected.
When the input service module detects that the first container system is located at the foreground, determining a corresponding application of the received input event in the first container system, for example, determining the corresponding application according to an application identifier carried in the input event; and sending the received input event to a corresponding application in the first container system, and performing response processing on the input event by the application.
S203: after the input service modules in other container systems receive the input event, if the other container systems are detected to be in the background, the input event is ignored.
In fact, only one container system can be located in the foreground, usually in the terminal equipment. Thus, when the first container system is detected in the above step as being in the foreground, the other container systems that are running are actually in the background. This step and step 202 above are actually performed during the duration that the first container system is in the foreground and the other container systems are in the background.
Specifically, for each other operating container system, after the input service module in the other container system receives the input event, the operating state of the other container system in which the input service module is located is detected. The received input event is ignored when the input service module detects that the other container system in which it is located is in the background.
S204: after receiving the content to be displayed sent by at least one application in the first container system, if the display service module in the first container system detects that the first container system is in the foreground, the display service module sends the received content to be displayed of each application to the kernel.
And the display service module in the first container system detects the running state of the first container system in which the input service module is positioned after receiving the content to be displayed, which is sent by at least one application in the first container system in which the display service module is positioned. The content to be displayed of each application comprises: the system desktop of the desktop application, the respective user interfaces of the other applications.
And when the input service module detects that the first container system is positioned at the foreground, the received content to be displayed of each application is sent to a display module in the kernel.
Preferably, the display service module in the first container system determines the system desktop and the visible area of each user interface according to the position, size and stacking sequence of the system desktop and each user interface in the first container system on the screen; synthesizing each visible area to ensure that the synthesized visible area does not exceed the area of the screen; and sending the synthesized visual area to a display module in the kernel.
S205: and after detecting that the other container systems are in the background, the display service module in the other container systems stops receiving the content to be displayed applied in the other container systems.
In fact, only one container system can be located in the foreground, usually in the terminal equipment. Thus, when the first container system is detected in the above step as being in the foreground, the other container systems that are running are actually in the background. This step and step 204 above are actually performed during the duration that the first container system is in the foreground and the other container systems are in the background.
Specifically, for each of the other container systems that operate, the display service module in the other container system detects the operating state of the other container system in which the display service module is located. And when the display service module detects that the other container system where the display service module is located at the background, stopping receiving the content to be displayed applied in the other container system where the display service module is located.
Obviously, the content to be displayed of other container systems located in the background cannot be sent to the display module of the kernel, so that the display module of the kernel can only receive the content to be displayed of the first container system located in the foreground, and then the display module in the subsequent kernel actually only displays and outputs the content of the first container system located in the foreground, thereby solving the problem of disordered display and output of different container systems and improving the experience of a user.
Moreover, the display module of the kernel does not need to process the contents to be displayed of other container systems positioned at the background, thereby greatly reducing the workload of the display module of the kernel.
S206: and the display module in the kernel displays and outputs the received content to be displayed.
When the display module in the kernel only receives the content to be displayed of the first container system in the foreground, but does not receive the content to be displayed of other container systems in the background; therefore, the display module in the kernel performs display output according to the received content to be displayed from the first container system, and the specific method for display output is well known to those skilled in the art and is not described herein again.
In fact, the combination of step S201 to step S203 and the combination of step S204 to step S206 are independent of each other. In the first embodiment of the present invention, for the combination of performing step S201 to step S203 and the combination of step S204 to step S206, the two combinations may be performed simultaneously, only one of the combinations may be performed, the combinations may be performed alternately, or respective times may partially overlap during the execution.
According to the multi-system-based input/output method in the first embodiment of the present invention, a multi-system-based input/output device is further provided in the first embodiment of the present invention, the device is disposed inside the terminal device of the present invention, and a schematic frame diagram of an internal structure of the device is shown in fig. 3, where the method includes: a kernel and more than two container systems.
Wherein, the kernel includes: an input module 301. The input module 301 is configured to send the input event to more than two container systems, respectively, after receiving the input event.
A first container system of the two or more container systems comprising: the input service module 311. The input service module 311 is configured to, after receiving the input event, send the input event to the corresponding application if it is detected that the first container system is in the foreground.
Other container systems of the two or more container systems include: the input service module 321.
The input service module 321 is configured to, after receiving the input event, ignore the input event if detecting that the other container system is in the background.
Preferably, the first container system further comprises: a service module 312 is displayed. The display service module 312 is configured to, after receiving the content to be displayed, sent by at least one application in the first container system, if it is detected that the first container system is in the foreground, send the received content to be displayed of each application to the kernel.
Preferably, the other of the two or more container systems further comprises: the service module 322 is displayed. The display service module 322 is configured to stop receiving the content to be displayed applied in the other container system after detecting that the other container system is in the background.
And, the kernel further comprises: a display module 302. The display module 302 is configured to perform display output on the received content to be displayed.
In fact, when the first container system is switched to the background and one of the other container systems is switched to the foreground, the functions of the input service module 311 of the first container system and the input service module 321 of the other container system in the foreground are exchanged; the display service module 312 of the first container system is functionally interchangeable with the display service module 322 of the other container system located in the foreground. That is, in practice, the input service module 311 has the same function as the input service module 321, and the display service module 312 has the same function as the display service module 322; the reference numerals differ only to the extent that they belong to different container systems.
In the first embodiment of the invention, the states of the foreground and the background of each container system are detected by the input service module of each container system; and acquiring the input event by the input service module of the first container system positioned in the foreground exclusive to the input device of the terminal device, and responding. The confusion situation that different container systems carry out false response on input events can be prevented, the user can be ensured to interact with the expected container system (namely the first container system switched to the foreground), and the user experience is improved.
In addition, in the first embodiment of the present invention, the display service module of the first container system in the foreground determines to send the content to be displayed in the first container system to the display device through the display module of the kernel for display and output, and the display service modules in the other container systems in the background determine to ignore the content to be displayed in the other container systems in which the display service modules are respectively located. The display service module of the first container system, which is equivalent to the foreground, monopolizes the display device of the terminal device to perform display output, so that the situation that the display device alternately outputs contents of different container systems in a short time to cause display confusion can be prevented, a user can be ensured to view the display contents of the expected container system, interaction with the expected container system of the user can be realized, and the user experience is improved.
Further, in the first embodiment of the present invention, the kernel may directly adopt linux kernel, and only the framework layer (for example, the surfaceflag module) of the container system is modified. In addition, the cross-platform portability of the first embodiment of the invention is better without depending on a specific hardware platform.
In addition, in the first embodiment of the present invention, the display module of the kernel does not need to process the contents to be displayed of other container systems located in the background, which greatly reduces the workload of the display module of the kernel, is favorable for reducing power consumption, and prolongs the endurance time of the terminal device.

The operating system may be a Linux operating system or a Unix operating system in the conventional sense, an Android system, an Ubuntu system and the like derived from the Linux operating system, a win system based on a Windows platform and the like. In fact, the container system of the present invention is not limited to the aforementioned exemplary operating systems, and may cover all operating systems capable of operating in a container. For convenience of description, the technical solution of the present invention is described below by taking an Android system as a container system as an example.
The container system according to the second embodiment of the present invention includes: a surfefinger (appearance thrower) module and an input module. The surface flag module and the input module interact with a plurality of applications, also called APPs (applications), in the container system, respectively.

Preferably, the master display module is modified from a display module in a conventional kernel. The master input module may be modified from the input module in a conventional kernel. Therefore, the master control system can be considered to be improved on the basis of the traditional kernel.
The surfafinger module and the input module in the container system in the second embodiment of the present invention interact with the main control display module and the main control input module in the main control system, respectively. Further, the solid line in fig. 4 represents data transmission (one kind of data interaction), and the dotted line represents data non-transmission (i.e., data interaction is not performed).
The display hardware and the input hardware in the second embodiment of the invention interact with the main control display module and the main control input module in the main control system respectively.
A flow chart of a multi-system-based input/output method according to a second embodiment of the present invention is shown in fig. 5, and includes the following steps:
s501: after receiving the input event, a main control input module in the main control system detects the foreground and background states of more than two container systems in the equipment and sends the input event to the container systems positioned on the foreground.
The main control input module in the main control system packages the input information of the user into an input event after receiving the input operation of the user through the input hardware in the terminal equipment, and detects the foreground and background states of all the running container systems in more than two container systems in the terminal equipment.
And the master control input module in the master control system sends the encapsulated input event to a first container system positioned in the foreground.
In fact, only one container system can be located in the foreground, usually in the terminal equipment. Thus, when the first container system is detected in the above step as being in the foreground, the other container systems that are running are actually in the background. The master input module in the master control system does not send the input event to other container systems in the background.
Therefore, in the step, the master control input module omits a container system which is used for inputting the event to the background, so that the workload of the master control input module is saved, and the power consumption of the master control input module is reduced.
S502: and when the input module in the first container system receives the input event, the input event is sent to the corresponding application in the first container system.
After an input module in the first container system receives an input event from the master control system, determining a corresponding application of the received input event in the first container system, for example, determining the corresponding application according to an application identifier carried in the input event; and sending the received input event to a corresponding application in the first container system, and performing response processing on the input event by the application.
Because the input module in other container systems does not receive the input event from the main control system, the workload for processing the input event can be saved, and the power consumption is reduced.
S503: and when the surfeFinger module in the first container system receives the content to be displayed, which is sent by at least one application in the first container system, sending the content to the master control system.
When the surfefinger module in the first container system receives the content to be displayed, which is sent by at least one application in the first container system where the surfefinger module is located, the received content to be displayed of each application is sent to a main control display module in the main control system. The content to be displayed of each application comprises: the system desktop of the desktop application, the respective user interfaces of the other applications.
Preferably, the surfefinger module in the first container system determines the visual areas of the system desktop and the user interfaces according to the positions, sizes and stacking sequence of the system desktop and the user interfaces on the screen in the first container system; synthesizing each visible area to ensure that the synthesized visible area does not exceed the area of the screen; and sending the synthesized visual area to a main control display module in a main control system.
S504: and when the surfeFinger module in the other container system receives the content to be displayed sent by at least one application in the other container system, sending the content to the master control system.
And when the surfeFinger module in other container system receives the content to be displayed sent by at least one application in other container system, sending the received content to be displayed of each application to the main control display module in the main control system. The content to be displayed of each application comprises: the system desktop of the desktop application, the respective user interfaces of the other applications.
Preferably, the surfefinger module in the other container system determines the visual area of the system desktop and each user interface according to the position, size and stacking sequence of the system desktop and each user interface on the screen in the other container system where the surfefinger module is located; synthesizing each visible area to ensure that the synthesized visible area does not exceed the area of the screen; and sending the synthesized visual area to a main control display module in a main control system.
S505: after receiving the contents to be displayed from the first container system and other container systems, a main control display module in the main control system detects the foreground and background states of the first container system and other container systems.
After receiving the contents to be displayed respectively sent by the surfeFinger module of the first container system and the surfeFinger modules of other container systems, the main control display module in the main control system detects the foreground and background states of the first container system and the other container systems which send the contents to be displayed.
S506: and if the main control display module detects that the first container system and the other container systems are respectively in the front and the back, the main control display module displays and outputs the content to be displayed from the first container system and ignores the content to be displayed from the other container systems.
In fact, only one container system can be located in the foreground, usually in the terminal equipment. Thus, when the first container system is detected as being in the foreground, the other container systems that are running are actually in the background.
And after detecting that the first container system and the other container systems are respectively in the front and the back, the main control display module displays and outputs the content to be displayed from the first container system and ignores the content to be displayed from the other container systems.
In fact, the combination of step S501 to step S502 and the combination of step S503 to step S506 are independent of each other. In the first embodiment of the present invention, for the combination of performing step S501 to step S502 and the combination of step S503 to step S506, the two combinations may be performed simultaneously, only one of the combinations may be performed, the combinations may be performed alternately, or respective times in the execution process may partially overlap.

The input module 611 is configured to send the input event to a corresponding application in the first container system after receiving the input event.
In fact, other container systems of the two or more container systems include: an input module 621. At this time, the other container system in which the input module 621 is located is in the background, and no input event is received.
Preferably, the first container system further comprises: a surfefinger module 612. The surfefinger module 612 is configured to send, after receiving the content to be displayed, sent by at least one application in the first container system, to the master control system.
And, other than the first container system, of the two or more containers, comprising: a surfefinger module 622. The surfefinger module 622 is configured to send, after receiving content to be displayed, sent by at least one application in another container system, to the master control system;

The main control display module 602 is configured to detect foreground and background states of the first container system and the other container systems after receiving content to be displayed from the first container system and the other container systems; and if the first container system and the other container systems are detected to be in the front and the background respectively, displaying and outputting the content to be displayed from the first container system, and ignoring the content to be displayed from the other container systems.
In fact, the input module 611 of the first container system is functionally identical to the input service module 321 of the other container system; the display module 612 of the first container system is functionally consistent with the display service module 322 of the other container systems. Different reference numerals only refer to systems belonging to different containers.
In the second embodiment of the present invention, the master control input module in the master control system detects the foreground and background states of each container system, and sends the received input event only to the first container system located in the foreground, but not to other container systems located in the background, which is equivalent to that the first container system monopolizes the input device to respond to the input event. The confusion situation that different container systems carry out false response on input events can be prevented, the user can be ensured to interact with the expected container system (namely the first container system switched to the foreground), and the user experience is improved.
In addition, in the second embodiment of the present invention, when both the first container system located in the foreground and the other container systems located in the background send the content to be displayed to the main control display module of the main control system, the main control display module determines to send only the content to be displayed of the first container system located in the foreground to the display device for displaying, and ignores the content to be displayed of the other container systems located in the background; the display device which is equivalent to the first container system at the foreground monopolizing the terminal device for display output can prevent the display device from alternately outputting the contents of different container systems in a short time to cause display disorder, ensure that a user can watch the display contents of the expected container system and interact with the expected container system of the user, and improve the experience of the user.
Furthermore, in the second embodiment of the present invention, only the kernel of linux needs to be modified to obtain the master control system, and the container system does not need to be modified; compatibility is enhanced, and the number of container systems is convenient to expand; for example, from a two-container system to a three-container system, a container is newly created without modifying the code of the newly added container system, and the newly added container system is installed in the container.
In addition, in the second embodiment of the present invention, the master control system does not send the input event to the other container systems located in the background, so that the other container systems located in the background do not need to process additional input events that do not need to be responded, thereby reducing the workload of the other container systems, facilitating to reduce the power consumption, and prolonging the endurance time of the terminal device.
