The present embodiment describes a specific connection procedure in a bluetooth connection manner. As shown in fig. 2D, when the slave electronic device 200 detects a slide down gesture on the status bar 218, the slave electronic device 200 may display a window 219 on the user interface 22 in response to the gesture. As shown in fig. 2E, a bluetooth switch control 219A and switch controls for other functions (e.g., Wi-Fi, mobile data, etc.) may be displayed in window 216. When an operation on the switch control 219A in the window 219 (such as a touch operation on the switch control 219A) is detected, the slave electronic device 200 may turn on bluetooth in response to the operation. As shown in fig. 2F, when the slave electronic device 200 and the master electronic device 100 are within the bluetooth detectable range, the user interface of the slave electronic device 200 displays a confirmation connection window 220, and when an operation of a control 220A (confirmation "connection") on the window 220 is detected (such as a touch operation on the control 220A), the user interface of the master electronic device 100 may display a confirmation connection window in response to the operation.

As shown in fig. 2G, the graphic user interface 21 of the master electronic device 100 displays a confirmation connection window 221, and when an operation (such as a touch operation on the switch control 221A) on the control 221A (confirmation "permission" connection) in the window 221 is detected, the slave electronic device 200 and the master electronic device 100 make a connection in response to the operation.

When the slave electronic device 200 and the master electronic device 100 are successfully connected, as shown in fig. 2I, the graphical user interface 21 on the master electronic device 100 displays the screen projection interface 300 of the slave electronic device 200.

In the embodiment of the application, a cooperative relationship is established between a master electronic device and a slave electronic device, the master electronic device has a function of distinguishing an input device, specifically, a touch screen operation for the master electronic device is detected, an application of the master electronic device is called, optionally, when the touch screen operation is performed on a screen projection interface of the master electronic device, a response result is displayed on the screen projection interface of the master electronic device, and further optionally, the response result is sent to the slave electronic device and displayed on the slave electronic device; when the touch screen is operated on the non-screen-projection interface of the main electronic device, the response result is displayed on the non-screen-projection interface of the main electronic device. And detecting touch screen operation aiming at the slave electronic equipment, calling an application of the slave electronic equipment, and displaying a response result on screen projection interfaces of the slave electronic equipment and the master electronic equipment. For convenience of description, in the following embodiments, the above-described function is referred to as a differentiated distributed input device function.

Optionally, in order to be compatible with the general screen projection function, the application may implement differentiation between the distributed input device function and the existing general screen projection function through the switch control. The universal screen projection function can mean that when a user touches a screen on a non-screen projection interface of the main electronic device, the application of the main electronic device is called, and the main electronic device responds to the screen touch operation; when the user touches the screen projection interface of the main electronic device for operation, the application of the slave electronic device is called, the slave electronic device responds to the touch screen operation, and the response result is displayed on the screen projection interface of the main electronic device.

The process of enabling the differentiation of the functions of the distributed input device is described below in two alternative embodiments.

(first) first alternative embodiment: the functions of the distributed input equipment are distinguished by turning on or off the function switch control.

Fig. 2A and 2B illustrate an operation of the electronic device 100 to enable distinguishing the functions of the distributed input device through a "function switch" control.

The user may make a slide-down gesture at the status bar 201 to open the window 216 and may click the "function switch" control 216B in the window 216 to conveniently open the "function switch". When the "function switch" is already on, the "function switch" may be turned off if the "function switch" control 216B is clicked again. The switch control 216B of the "function switch" may be represented in the form of a text message or an icon.

In the embodiment of the present application, after the "function switch" is turned on through the operations shown in fig. 2A and fig. 2B, the electronic device 100 turns on the function of distinguishing the distributed input devices, that is, when the master electronic device 100 and the slave electronic devices cooperate, the touch operation comes from the master electronic device, and an application on the master electronic device is called to respond to the touch operation. The touch operation comes from the slave electronic equipment, and the application on the slave electronic equipment is called to respond to the touch operation.

When the "function switch" is turned off, the electronic device 100 turns off the function of distinguishing the distributed input devices and calls the general screen projection function. That is, when the master electronic device 100 and the slave electronic device cooperate, a touch operation is performed on a non-screen-projection interface of the master electronic device, and an application on the master electronic device is called to respond to the touch operation; and performing touch operation on the screen projection interface of the slave electronic equipment or the master electronic equipment, and calling the application on the slave electronic equipment to respond to the touch operation.

The "function switch" may be turned on by default or turned off by default, and a user may set the "function switch" autonomously to turn on or turn off, which is not limited in the embodiments of the present application.

(second) second alternative embodiment: and the function of the distributed input equipment is opened or closed by using a 'switching equipment' control.

Fig. 3A and 3B illustrate an operation of the main electronic device 100 to turn on or off the function of distinguishing distributed input devices using a "toggle device" control.

In some embodiments, the master electronic device 100 may turn on the differentiated distributed input device function by default. When the master electronic device 100 and the slave electronic device 200 have established a collaborative relationship, as shown in fig. 3A, a notification bar of a user interface of the master electronic device 100 may display a window 301, which prompts a user to close the function of distinguishing the distributed input devices, switch to the original device, and invoke an application of the original device to respond to a touch operation of the screen projection interface, that is, turn on the universal screen projection function. Prompt 301A, prompt 301B, stow notification control 301C, "disconnect" control 301D, "switch device" control 301E may be displayed in window 301.

The prompt 301A may be used to introduce that the main electronic device 100 is connected to another electronic device, establish a collaborative relationship, and display a connection duration.

The prompt message 301B may be used to introduce a connection object of the main electronic device 100, and prompt the user that the main electronic device 100 and the electronic device of the corresponding model establish a collaborative relationship.

Control 301C may be used to listen for operations (e.g., touch operations) to collapse window 301, and control 301C may be represented in the form of an icon or textual information.

Control 301D may be used to listen for an operation (e.g., a touch operation) to disconnect the device. When the operation acting on the control 301C is detected, the master electronic device 100 is disconnected from the slave electronic device 200, and the two electronic devices cannot cooperate with each other, so that data sharing is realized.

Control 301E can be used to listen for an operation (e.g., a touch operation) that turns off the functionality of the differentiated distributed input device. When an operation on control 301E is detected, for example, clicking "toggle device", main electronic device 100 turns off the function of distinguishing the distributed input devices and uses the general screen projection function. At this time, as shown in fig. 3B, the user interface notification bar display window 302 of the main electronic device 100.

Window 302 differs from window 301 in control 302A and control 301E. The control 302A may be used to listen for an operation (e.g., a touch operation) that turns on the functionality of the differentiated distributed input devices. When an operation is detected that acts on control 302A, such as clicking "use default device," master electronic device 100 reopens the functionality of distinguishing distributed input devices. At this time, as shown in fig. 3A, the user interface notification bar of the main electronic device 100 displays the window 301 again.

In the following, some embodiments of the user using the function of distinguishing the distributed input devices when the main electronic device uses two electronic devices to work cooperatively are described with reference to three different usage scenarios.

Use scenario one: text entry scenario

The embodiments shown in fig. 4A-4I take a text input scenario as an example to illustrate the process of implementing the function of distinguishing distributed input devices on an electronic device. In a text entry scenario, a user interface of the electronic device may display a "text entry interface" provided by the application.

In some embodiments, the "text input interface" is used to display a text box in which text can be input, which displays an input focus in response to an operation (touch operation or the like) by the user, waiting for a text input result by the user.

The scenarios exemplarily illustrated in fig. 4A-4I may be one implementation of a "text entry scenario". This scenario includes two electronic devices, a master electronic device 100 and a slave electronic device 200, with the interface content of the slave electronic device being displayed on the master electronic device in a projected screen, and the projected screen interface 300 of the master electronic device displaying the interface content of the slave electronic device.

As shown in fig. 4A, the user interface of the screen-projection interface 300 on the main electronic device 100 is a "text input interface" which may be provided by an application (e.g., a browser) having a text input scenario. The user interface may be a user interface where a user clicks a browser icon of the in-view screen projection interface 300 and prepares to enter a search target in the browser search bar 401.

As shown in fig. 4A, an operation (e.g., a touch operation) acting on the browser search bar 401 in the screen projection interface 300 on the main electronic device 100 is detected, the browser search bar 401 of the screen projection interface 300 displays an input focus 402 as shown in fig. 4B, invokes an input method application of the main electronic device, displays an input method interface 403, and waits for a user input.

As shown in fig. 4C, in response to an input result submission operation by the user, the input result 404 is displayed in the browser search bar of the screen-projection interface 300 and also displayed in the browser search bar of the slave electronic device 200.

The touch operation is not limited to the left blank position in the browser search bar 401 of the screen-projection interface 300, and the touch operation may be performed at other positions of the browser search bar 401, such as the middle or right blank position.

As shown in fig. 4D, when an operation (e.g., a touch operation) acting on the browser search field 405 of the slave electronic device 200 is detected, the browser search field 405 of the slave electronic device 200 displays an input focus 406 as shown in fig. 4E, invokes an input method application of the slave electronic device 200, and displays an input method interface 407, waiting for a user input. This input method interface is also displayed on the screen-projection interface 300. As shown in fig. 4F, in response to the input result submission operation by the user, the input result 408 is displayed in the browser search bar of the slave electronic device 200, and is also displayed in the browser search bar of the screen-projection interface 300. The touch operation is not limited to the left blank position in the browser search field 405 of the slave electronic device 200, and the touch operation may be performed at another position of the browser search field 404, for example, a middle or right blank position.

As shown in fig. 4G, an operation (e.g., a touch operation) on the browser search field 409 of the non-screen-projection interface on the main electronic device 100 is detected, the browser search field of the main electronic device displays the input focus 410 as shown in fig. 4H D, the input method application of the main electronic device is invoked, the input method interface 411 is displayed, and a user input is waited for. As shown in fig. 4F, in response to an input result submission operation by the user, an input result 412 is displayed in the browser search bar of the main electronic device.

With the embodiments exemplarily shown in fig. 4A-4I, the master electronic device may respond to an input operation using a differentiated distributed input device function in a text input scenario, that is, when a touch operation is performed on a screen projection interface of the master electronic device, an input method of the master electronic device may be called, and when a touch operation is performed on a slave electronic device, an input method of the slave electronic device may be called to respond to an input operation. That is, the electronic device may distinguish the input source, and invoke the input method corresponding to the source to respond to the input in the text input scenario. Therefore, on the main electronic equipment, even if the screen projection interface is stretched, the input method interface responding to the touch operation of the screen projection interface can not be stretched synchronously with the window, but the input method on the main electronic equipment is used, the size of the interface is unchanged, and the user experience is good. Illustratively, the slave electronic device 200 is a mobile phone, the master electronic device 100 is a tablet computer, and a user touches a screen on a screen-projecting interface on the tablet computer to input a text, and may invoke an input method on the tablet computer, where the input method interface is larger than the input method interface of the mobile phone and does not change in size with the screen-projecting interface, so that the text can be conveniently input.

The page layout of the "text input interface" may also take other forms, which are not limited to those shown in fig. 4A to 4I, and this is not limited by the embodiment of the present application. Not limited to browser applications, other applications (e.g., notes, qq, etc.) may also provide similar "text input interfaces," where the applications provide a "text input interface," a master electronic device in conjunction with other slave electronic devices may also provide differentiated distributed input device functionality in a manner similar to that described above with respect to fig. 4A-4I.

(II) usage scenario II: image capture scene

The scenes exemplarily illustrated in fig. 5A-5F may be one implementation of an "image capture scene".
