Currently, users may cooperatively use multiple devices or multiple screens to improve the efficiency of use and user experience. For example, a user's notebook computer may be externally connected to a display (or screen), so that the user may use a set of input devices to control both the screen of the notebook computer and the screen of the external display. By way of example, the input device may include a standard human interface device (human INTERFACE DEVICE, HID), such as a keyboard, mouse, joystick, touch pad, or the like.

However, in the existing scheme, when the device of the user is externally connected with the display, the input device can only input to one place at the same time, and a plurality of users cannot control different screens at the same time, so that the efficiency of simultaneous use of multiple users is affected.

Based on the above, the embodiment of the application provides a display method and electronic equipment, and the method can be applied to a scene in which the electronic equipment is externally connected with a display or a scene in which a plurality of electronic equipment are cooperatively used, so that a solution is provided for a scene in which multiple users are simultaneously used.

Several exemplary use scenarios provided by embodiments of the present application are described below in conjunction with the accompanying drawings.

FIG. 3 is a set of graphical user interfaces (GRAPHICAL USER INTERFACE, GUI) provided by an embodiment of the present application.

As shown in fig. 3, the notebook computer is externally connected with a display, and the notebook computer displays a memo application, and at the same time, a game application run by the notebook computer can be displayed on the externally connected display. That is, a plurality of display screens are controlled by one electronic device. The notebook computer can be externally connected with a mouse, and the display can be externally connected with a game handle. Further, the user 1 can operate the memo application through the keyboard and the mouse of the notebook computer, and the user 2 can control the game application displayed on the display through the gamepad. The two users can operate at the same time and do not interfere with each other. It will be appreciated that the notebook computer may also be externally connected with two or more displays for more users to operate simultaneously,

For example, the notebook computer and the display may be connected by a wired connection or a wireless connection. The input device and the notebook (or display) may also be connected by wire or wirelessly. The wireless connection may be a high-fidelity wireless communication (Wi-Fi) connection, a bluetooth connection, an infrared connection, an NFC connection, a ZigBee connection, or the like. The wireless connection may also be a long range connection including, but not limited to, a mobile network supporting 2g,3g,4g,5g and subsequent standard protocols. For example, multiple electronic devices may log onto the same user account (e.g., hua as an account) and then make a remote connection through a server. By way of example, the plurality of electronic devices may be connected by a super terminal (e.g.: a super terminal composed of multiple devices).

FIG. 4A illustrates another set of GUIs provided by an embodiment of the present application.

As shown in fig. 4A, the notebook computer and the tablet may be in a collaborative mode, with the notebook computer and the tablet running respective systems, i.e., the systems of the two devices controlling respective screens, respectively. For example, the notebook computer and the tablet may be connected by a wired connection or a wireless connection, and the input device and the notebook computer (or tablet) may be connected by a wired connection or a wireless connection. The system of the notebook computer runs the memo application, the system of the tablet computer runs the chat application, and a mouse externally connected with the notebook computer can pass through the tablet. If the user selects to use the externally connected mouse control panel of the notebook computer, when the user 1 uses the externally connected mouse control panel of the notebook computer, the user 2 can simultaneously use the keyboard of the notebook computer to input the memo application, and the two users can simultaneously operate without interference. It will be appreciated that fig. 4 is presented by way of example with two devices having independent systems cooperating, and the present application is not limited to the number of devices in a cooperating mode.

FIG. 4B illustrates another set of GUIs provided by an embodiment of the present application.

As shown in fig. 4B, the notebook computer and the tablet may be in a collaborative mode, the notebook computer and the tablet may operate their respective systems, and the tablet may be externally connected to a display. The notebook computer and the tablet may be connected by a wired or wireless connection, the tablet and the external display may be connected by a wired or wireless connection, and the input device and the notebook computer, the tablet, or the external display may be connected by a wired or wireless connection. The system of the notebook computer runs the memo application, the system of the tablet computer runs the chat application, and meanwhile, the game application running on the tablet computer can be displayed on an external display. In this scenario, if the user selects to use the external mouse control tablet of the notebook computer, when the user 1 uses the external mouse control tablet of the notebook computer, the user 2 can simultaneously use the keyboard of the notebook computer to input the memo application, and simultaneously, the user 3 can control the game application displayed on the external display through the game handle, and the three users can simultaneously operate without interference. It will be appreciated that in this scenario, the notebook computer and tablet computer may each be externally connected to one or more displays, as the notebook computer and tablet computer operate independent systems, as the application is not limited in this regard.

In some embodiments, a user may associate an input device with a corresponding device through an interactive interface. For example, in the embodiment shown in fig. 3, when the user connects the external mouse to the notebook computer, the user can select the external mouse to control the notebook computer or the display through the configuration interface, and similarly, when the user connects the game handle to the notebook computer or the display, the user can also select the game handle to control the notebook computer or the display through the configuration interface. For another example, in the embodiment shown in fig. 4A, when the user accesses the external mouse to the notebook computer, the user may select the external mouse through the configuration interface to control the notebook computer or the tablet.

In other embodiments, the device corresponding to the input device may be associated with itself according to the scene. For example, in the embodiment shown in fig. 3, when the user connects the joystick to the notebook computer or the display screen, the notebook computer may associate the joystick with the display by default, because the interface displayed on the display screen at this time is a game application interface.

By the method provided by the embodiment of the application, the input device can be associated with the device or screen which needs to be controlled. Furthermore, a plurality of users can respectively control a plurality of devices or screens without interference. The method provided by the embodiment of the application can be applied to a scene of controlling a plurality of screens by one device, such as a scene of externally connecting a display by one device (shown in figure 3), a scene of controlling a plurality of display screens of a vehicle by one system, and the like. The method provided by the embodiment of the application can also be applied to a scene that a plurality of devices respectively control a plurality of screens, for example, a scene that a plurality of devices work cooperatively (as shown in fig. 4A). The method provided by the embodiment of the application can also be applied to a scene (shown in fig. 4B) that a plurality of devices respectively control respective screens and at least one device is externally connected with a display, and the application is not limited to this.

Two sets of GUIs in the embodiment of the present application are described above with reference to fig. 3, fig. 4A and fig. 4B, and the implementation process of the technical solution of the embodiment of the present application is described below with reference to the accompanying drawings.

Fig. 5 shows a schematic diagram of interactions between modules of an electronic device in a scenario in which one electronic device controls multiple screens. For example, a scene in which a plurality of screens are controlled by one device is shown in fig. 3. The hardware and software structures of the electronic device may be described with reference to fig. 1 and 2 with respect to the electronic device 100.

In some embodiments, as shown in fig. 5, an electronic device may include a multi-device input management module, an input subsystem, a screen management subsystem, and a screen display subsystem. Wherein the multi-device input management module may be used to manage correspondence between input devices and screens, manage cursors on different screens, etc. An input subsystem may be used to be responsible for managing the input devices, handling input events. The screen management subsystem may be used to take care of the processing of the display screen. The graphics display subsystem may be responsible for rendering content on a screen. As shown in fig. 5, the method may include, but is not limited to, the steps of:

S501: the multi-device input management module obtains screen information from the screen management subsystem.

Wherein the screen information may include information of all screens in the current system. Typically, each screen has a different screen identifier (DISPLAY ID), and the screen identifier is designated to determine which screen to display on, thus enabling multi-screen display.

For example, the screen information may include screen identifiers of all screens in the current system, and the multi-device input management module may obtain the screen identifiers corresponding to all the screens in the current system from the screen management subsystem. Alternatively, the screen management subsystem may monitor changes in the screen, e.g., adding a screen, removing a current screen, etc., in real time or at intervals. The multi-device input management module may obtain updated screen information from the screen management subsystem when a screen change occurs.

Still further exemplary, the screen information may also include configuration information, such as size, resolution, etc., of all screens in the current system. Optionally, the multi-device input management module may also obtain updated screen information from the screen management subsystem as the configuration (e.g., size, resolution) of the current screen changes.

S502: the multi-device input management module obtains input device information from the input subsystem.

Wherein the input device information may include information of all input devices in the current system. By way of example, the input device information may include identification, type information, etc. of all input devices in the current system. The multi-device input management module may perform classification management on the input devices according to the types of the input devices (e.g., mouse, keyboard, etc.). Alternatively, the input subsystem may monitor changes in the input device in real time or at intervals, e.g., adding an input device, removing a current input device, etc. The multi-device input management module may obtain updated input device information from the input subsystem when the input device changes.

As yet another example, the input device information may also include configuration information for all input devices in the current system, such as whether the input device supports cursor manipulation, etc. Optionally, the multi-device input management module may also obtain updated input device information from the input subsystem when a configuration of the input device changes.

It will be appreciated that the step S501 and the step S502 may be performed simultaneously or sequentially, and the execution sequence of the step S501 and the step S502 is not limited in the present application.

S503: the multi-device input management module determines an association between the screen and the input device.

In one implementation, a user may manually configure an association between a screen and an input device through a configuration interface, and further, the multi-device input management module may obtain the association between the screen and the input device according to a setting of the user. In another implementation, the system may automatically determine an association between the screen and the input device according to a scenario, a user habit, and the like, and further, the multi-device input management module may determine the association between the screen and the input device. The present application is not limited in the process and manner of associating a screen with an input device.

Optionally, the user may configure cursor patterns of different input devices or different screens through the configuration interface, and further, the multi-device input management module may obtain the cursor patterns of different input devices or different screens according to the setting of the user. The cursor style may include, among other things, the shape, color, etc. of the cursor display. Thus, the user can distinguish different screens through different cursor patterns, and the use efficiency of multiple users is improved.

S504: the input subsystem obtains an association between the screen and the input device from the multi-device input management module.

Optionally, the input subsystem may also obtain cursor patterns for different input devices or different screens from the multi-device input management module.

S505: when the input device is a cursor attribute and there is no cursor on the screen with which the input device is associated, the input subsystem creates a cursor on the screen with which the input device is associated.

Where the input device is a cursor attribute, it is understood that the input device supports cursor operations. For example, the INPUT subsystem may determine whether the INPUT DEVICE supports CURSOR operation based on characteristics of the INPUT DEVICE, e.g., when the INPUT DEVICE has an INPUT_DEVICE_CLASS_CURSOR characteristic, the INPUT DEVICE may be considered to support CURSOR operation.

It will be appreciated that since only one cursor need be displayed on each screen, the input subsystem may not need to recreate the cursor when the cursor was originally present on the screen associated with the input device, and may create the cursor on the screen associated with the input device when the cursor was not originally present on the screen associated with the input device. In this way, at most one cursor can be arranged on each screen, and the interference of the user operation is avoided.

S506: the input subsystem distributes events to the graphics display subsystem.

S507: the graphic display subsystem displays a cursor on a screen corresponding to the input device.

Alternatively, the graphic display subsystem may display the cursor on the screen corresponding to the input device in a corresponding cursor style according to the cursor style corresponding to different input devices or different screens.

Through the steps, the corresponding relation between the input equipment and the screen can be established. Further, the method may further include:

S508: the input subsystem detects a first input event and determines a screen on which the first input event is acting.

For example, when a user operates a first input device, the input subsystem may detect a first input event corresponding to the first input device.

In a possible implementation manner, in step S504, the input subsystem may obtain an association relationship between the screen and the input device from the multi-device input management module, and in step S508, the input subsystem may determine, according to the association relationship between the screen and the input device and the first input device corresponding to the first input event, a screen on which the first input event acts.

In another possible implementation, the first input event may be sent to the multi-device input management module when the input subsystem detects the first input event. The multi-device input management module may determine a screen on which the first input event acts according to an association between the screen and the input device and the first input device corresponding to the first input event. Further, the multi-device input management module may send the screen acted upon by the first input event to the input subsystem, such that the input subsystem may obtain the screen acted upon by the first input event. Alternatively, in this implementation, in step S504, the input subsystem may not need to obtain the association relationship between the screen and the input device from the multi-device input management module.

S509: the input subsystem distributes input events to the graphical display subsystem.

S510: the graphic display subsystem displays a cursor on a screen corresponding to the input device.
