This application relates to the field of terminal technologies, and in particular, to an input device connection method, a device, and a system.
With diversified development of terminal technologies, a terminal device usually used by a user in daily life or work gradually changes from a single device to a plurality of devices. Generally, the terminal device may be connected to one or more input devices, to implement a corresponding function. For example, the input device may be a wireless peripheral.
However, when the user simultaneously uses a plurality of terminal devices, the user needs to carry and maintain input devices matching the plurality of terminal devices. For example, when the user simultaneously uses a personal computer (PC) 1 and a PC 2, if the PC 1 and the PC 2 are separately configured with a set of mouse and keyboard, the user needs to perform operations alternately between a mouse 1 and a keyboard 1 that match the PC 1 and a mouse 2 and a keyboard 2 that match the PC 2. Alternatively, if two terminal devices share a set of input devices, the user needs to manually cut off a connection relationship between the set of input devices and one terminal device, and reconfigure a connection relationship between the set of input devices and the other terminal device. For example, when the user controls the PC 1 through a mouse connected to the PC 1, if the user wants to operate the PC 2 through the same mouse, the user needs to manually cut off a connection relationship between the mouse and the PC 1, and reconfigure a connection relationship between the mouse and the PC 2. The foregoing two methods are very complex and inefficient.
This application provides an input device connection method, a device, and a system, to reduce operation complexity of inputting information to a plurality of devices, and improve input efficiency.
To achieve the foregoing objectives, the following technical solutions are used in embodiments of this application.
According to a first aspect, an input device connection method is provided. The method is applied to a communication system, the communication system includes a first input device, a first terminal device, and a second terminal device, and the method includes: When the first input device is in a multi-connection working mode, the first input device maintains communication connections to both the first terminal device and the second terminal device. The first terminal device sends, to the first input device, migration indication information indicating the first input device to perform focus device switching. The first input device switches a focus device from the first terminal device to the second terminal device in response to the migration indication information. Before the first input device switches the focus device from the first terminal device to the second terminal device, the first input device is configured to input information to the first terminal device; and after the first input device switches the focus device from the first terminal device to the second terminal device, the first input device is configured to input information to the second terminal device.
That an input device performs focus migration specifically means that a focus device of the input device is switched from one terminal device (that is, a source host) to another terminal device (that is, a target host). It should be noted that, after the input device migrates from one terminal device (that is, the source host) to another terminal device (that is, the target host), a communication connection between the input device and the source host is not disconnected. A focus device is a terminal device that establishes a communication connection to an input device and can be directly controlled by the input device currently. A non-focus device is a terminal device that establishes a communication connection to an input device but cannot be directly controlled by the input device currently.
According to the solution provided in the first aspect, a same input device (for example, the first input device) may randomly perform focus migration between a plurality of terminal devices (for example, the first terminal device and the second terminal device). Before and after focus migration, the input device may simultaneously maintain communication connections to the plurality of terminal devices, and exchange, in a background, information with a non-focus device based on a communication connection between the input device and the non-focus device. Based on this, the input device can implement seamless focus migration between a plurality of terminal devices, to ensure that no interface display freezing occurs during switching, and implement an effect of seamless continuation of the input device across devices. In addition, according to this method, information synchronization does not need to rely on a wireless local area network (WLAN), that is, the plurality of terminal devices do not need to connect to a same WLAN.

The first input device sends, to the second terminal device, the information about the position at which the mouse cursor slides out of the display of the first terminal device, so that the second terminal device determines an initial position of the mouse cursor on a display of the second terminal device. In an example, the method provided in this application may be used for seamless focus device switching of a wireless mouse between a plurality of terminal devices. The source host (for example, the first terminal device) may synchronize, to the target host (for example, the second terminal device) through the wireless mouse, the information about the position at which the mouse cursor slides out of the display of the first terminal device, so that the target host continues the source host (for example, the first terminal device) to display the mouse cursor, thereby implementing an effect of seamless continuation of the mouse cursor across devices.
In a possible implementation, that the first terminal device sends migration indication information to the first input device includes: The first terminal device sends the migration indication information to the first input device when detecting that the mouse cursor tends to slide to another terminal device.

In a manner, the source host (for example, the first terminal device) may determine the target host based on the information about the position at which the mouse cursor slides out of the display of the first terminal device and the position sorting among the plurality of terminal devices represented by the obtained multi-device connection configuration information. This manner provides a possible use scenario.
In a possible implementation, the method further includes: the first terminal device determines the multi-device connection configuration information of the first input device based on position sorting among a plurality of terminal devices that is customized by a user on a user interface.

FIG. F 5 is a diagram of two working modes of a wireless mouse according to an embodiment of this application;
The following describes the technical solutions in embodiments of this application with reference to the accompanying drawings in embodiments of this application. In description in embodiments of this application, “/” means “or” unless otherwise specified. For example, A/B may represent A or B. In this specification, “and/or” describes only an association relationship for describing associated objects and represents that three relationships may exist. For example, A and/or B may represent the following three cases: Only A exists, both A and B exist, and only B exists. In addition, in the descriptions in embodiments of this application, “a plurality of” means two or more.
The terms “first” and “second” mentioned below are merely intended for a purpose of description, and shall not be understood as an indication or implication of relative importance or implicit indication of the number of indicated technical features. Therefore, a feature limited by “first” or “second” may explicitly or implicitly include one or more features. In the description of embodiments, unless otherwise specified, “a plurality of” means two or more.
It may be understood that the terminal device may be generally connected to one or more input devices (for example, an input peripheral), to implement a corresponding function. For example, a personal computer (personal computer, PC) may be connected to a mouse, and functions such as moving a cursor on a PC display and further opening/deleting a file are implemented through the mouse. The PC may alternatively be connected to a keyboard, and functions such as moving a cursor on a PC display, entering characters, and further opening/deleting a file are implemented through the keyboard. For another example, a tablet computer may be connected to a keyboard, and functions such as entering characters to the tablet computer and opening an application/a video/an audio in the tablet computer are implemented through the keyboard.
Based on a conventional method, when a user simultaneously uses a plurality of terminal devices, because the user needs to carry and maintain input devices matching the plurality of terminal devices, or the user needs to manually disconnect/reconfigure a connection relationship between the input device and the terminal device, a process in which the user controls the plurality of devices is very complex and inefficient.
To provide more convenient multi-device operation experience, in an implementation, the input device may be controlled to switch between a plurality of devices, so as to implement flexible operations or control on a plurality of terminal devices by using a set of input devices.
For example,
In addition, as shown in
In the method shown in
However, for the input device switching method shown in
To resolve the foregoing problem and provide more intelligent multi-device operation experience, an embodiment of this application provides an input device connection method. The method may be applied to a multi-device (that is, multi-terminal) interconnection and interworking scenario, to implement random migration of a same input device between a plurality of devices.
In an example, in this embodiment of this application, the input device is, for example, a wireless peripheral. The wireless peripheral is an input device that implements input to the terminal device based on a wireless transmission protocol (for example, a Bluetooth protocol or a 2.4G communication protocol).
In this embodiment of this application, an input manner supported by the input device may include but is not limited to a key manner (for example, a mouse or a keyboard), a scrolling wheel manner (for example, a mouse), a gesture input manner, a body language input manner, a voice input manner, an emoticon input manner, and an eye movement input manner.
Further, a specific manner of communication between the input device and the terminal device is not limited in embodiments of this application. For example, the input device is a Bluetooth peripheral. The Bluetooth peripheral may communicate with the terminal device based on a Bluetooth protocol that supports an inter-device multi-connection protocol stack, to implement migration from one terminal device to another terminal device.
In this embodiment of this application, that the input device migrates from one terminal device to another terminal device specifically means that a focus device of the input device is switched from one terminal device (that is, the source host) to another terminal device (that is, the target host). After the input device migrates from one terminal device (that is, the source host) to another terminal device (that is, the target host), a communication connection between the input device and the source host is not disconnected. A focus device is a terminal device that establishes a communication connection to an input device and can be directly controlled by the input device currently. A non-focus device is a terminal device that establishes a communication connection to an input device but cannot be directly controlled by the input device currently. A process in which the input device migrates from the PC 1 (that is, the source host) to the PC 2 (that is, the target host) is used as an example. Before the migration, the focus device of the input device is the PC 1; and after the migration, the focus device of the input device is the PC 2. Before the migration, the input device is configured to control the PC 1; after the migration, the input device is configured to control the PC 2.

It should be noted that the structure included in the input device 300 shown in
In this embodiment of this application, the input device has a capability of simultaneously maintaining communication connections to a plurality of devices. In an example, in this embodiment of this application, the input device may work in a normal mode, or may work in a multi-connection mode. The multi-connection mode is a working mode in which communication connections are simultaneously maintained to a plurality of terminal devices. Comparatively, the normal mode is a working mode in which a communication connection is maintained to only a single terminal device. In this embodiment of this application, the input device in the multi-connection mode simultaneously maintains communication connections to a plurality of terminal devices, so that the input device can implement seamless synchronous migration of a focus between the plurality of terminal devices.
Further, in this embodiment of this application, the input device has a capability of providing a plurality of media access control (MAC) addresses.
Further, in this embodiment of this application, the input device has a capability of maintaining communication connections to a plurality of devices through a plurality of MAC addresses. One MAC address may be used by the input device to establish a communication connection to one terminal device and perform subsequent communication.
In an example, a multi-device connection shortcut switch may be disposed on the input device, so that when the user has a requirement for cross-device focus migration of the input device, a multi-device connection function can be enabled by using the shortcut switch in one click. After the input device in the normal mode receives an operation of enabling the multi-device connection function by the user, the input device enters the multi-connection mode from the normal mode. After the input device in the multi-connection mode receives an operation of disabling the multi-device connection function by the user, the input device enters the normal mode from the multi-connection mode.

For example, the input device may switch a Bluetooth channel, send a Bluetooth proximity discovery pairing broadcast, to discover a connectable terminal device around. Further, if a terminal device receives an operation of tapping to confirm a Bluetooth connection by the user, the terminal device completes Bluetooth pairing with the input device, and establishes the Bluetooth connection.
In another possible implementation, that the input device establishes a wireless connection or wireless connections to one or more terminal devices other than the focus device after the input device enters the multi-connection mode may include: The input device is reconnected to the one or more terminal devices that are previously connected. It may be understood that, after the input device enters the multi-connection mode, for the one or more terminal devices that are previously connected to the input device, the input device does not need to perform device discovery, authentication, and pairing again, but may directly perform reconnection based on stored pairing information.
After the input device enters the multi-connection mode, the terminal device connected to the input device includes a focus device and a non-focus device. As shown in (a) in
It should be noted that

In an example in which the input device communicates with the terminal device based on the Bluetooth protocol, the Bluetooth protocol that supports the multi-connection protocol stack is, for example, a Bluetooth 5.0 protocol or a next-generation protocol version of the Bluetooth 5.0 protocol. For specific details of supporting the multi-connection protocol stack in the communication protocol, refer to specific improvement details in the protocol (for example, the Bluetooth 5.0 protocol).

Further, the wireless mouse may obtain movement information like a movement position of the mouse cursor by using the cursor module. Further, the wireless mouse may send the movement information of the mouse cursor to the first device by using the Bluetooth module based on a Bluetooth connection between the wireless mouse and the first device.

Phase 1: Enter a multi-connection mode.
For example, after the user enables a multi-device connection function of the wireless mouse, the wireless mouse may enter the multi-connection mode from the normal mode.
Phase 2: Focus migration of the input device.
For example, when detecting that the mouse cursor tends to slide to another device, a source host indicates the wireless mouse to perform focus device switching.

For example, after the wireless mouse completes focus device switching, a target host receives information input by the input device instead.

That is, the phase 1 may include S902B and S903 shown in
The first device may prompt (for example, a pop-up prompt or a voice prompt) the user to enable the multi-device connection function of the wireless mouse when detecting that the mouse cursor slides to an edge of a screen and still tends to slide out of the edge.
In an example in which the wireless mouse directly enters the multi-device connection mode based on an indication of the first device, the following case 5 exists.
Case 5: The first device may indicate the wireless mouse to enter the multi-connection mode when detecting that the mouse cursor slides to the edge of the screen and still tends to slide out of the edge. That is, the phase 1 may include S903 shown in
S902A, S902B, and S903 to S908 are specifically as follows:
S902A: The first device sends a working mode switching instruction to the wireless mouse when receiving a second operation performed by the user on the UI interface.
The UI interface is, for example, a UI interface used to manage a multi-connection mode related configuration or operation. The second operation is, for example, an operation of enabling the multi-device connection function of the wireless mouse. The working mode switching instruction instructs the wireless mouse to switch to the multi-connection mode, for example, switch from the common mode to the multi-connection mode.
In an example, the first device may provide an option used by the user to select the multi-device connection function of the wireless mouse, so that the user performs setting based on an actual requirement.
S902B: The wireless mouse receives a third operation of the user.
The third operation is an operation of turning on the multi-device connection shortcut switch set on the wireless mouse.
S903: The wireless mouse establishes wireless communication connections to the second device and the third device.
After the wireless mouse receives the third operation of the user or receives the working mode switching instruction from the first device, the wireless mouse enters the multi-connection mode, and establishes the wireless communication connections to the second device and the third device. After the wireless mouse enters the multi-connection mode and establishes the wireless communication connections to the second device and the third device, the first device is a focus device of the wireless mouse, and the second device and the third device are non-focus devices of the wireless mouse. In other words, the wireless mouse may directly control the first device currently.
In a possible implementation, the wireless mouse may establish the wireless communication connection to the second device through the first MAC address and perform subsequent communication, and establish the wireless communication connection to the third device through the second MAC address and perform subsequent communication.
For example, the wireless mouse is a Bluetooth mouse. In a possible implementation, if the wireless mouse has not performed Bluetooth pairing with neither the second device nor the third device previously, that the wireless mouse establishes the wireless communication connections to the second device and the third device may include: First, the wireless mouse discovers the second device and the third device that are connectable around. Then, the wireless mouse performs authentication on both the second device and the third device. Finally, after the authentication succeeds, the wireless mouse separately performs pairing with the second device and the third device, to establish Bluetooth connections to the second device and the third device.
In another possible implementation, if the wireless mouse has successfully performed Bluetooth pairing with the second device or the third device previously, for example, the wireless mouse has previously established a Bluetooth connection to the second device or the third device, that the wireless mouse establishes a wireless communication connection to the second device may include: The wireless mouse is directly reconnected to the second device based on previously stored pairing information; and that the wireless mouse establishes a wireless communication connection to the third device may include: The wireless mouse is directly reconnected to the third device based on previously stored pairing information.
In an example, the wireless mouse may maintain communication connections to the second device and the third device in a background. For example, the wireless mouse may maintain communication connections to the second device and the third device by sending a heartbeat packet.
In a possible implementation, after the wireless mouse enters the multi-connection mode and establishes the wireless communication connections to the second device and the third device, the first device may detect a position of the mouse cursor on a display of the first device in real time, to send migration indication information to the wireless mouse when detecting that the mouse cursor tends to slide to another terminal device (that is, perform the following S904).
In some embodiments, if the wireless mouse has successfully performed Bluetooth pairing with the second device and the third device previously, in consideration of device and information security, after the wireless mouse is reconnected to the second device and the third device based on the previously stored pairing information, the wireless mouse may notify the second device and the third device that the wireless mouse is currently in the multi-connection mode. Further, in some embodiments, after receiving the notification that the wireless mouse is currently in the multi-connection mode, both the second device and the third device may notify (for example, a pop-up notification) the user that related permission of the wireless mouse in the multi-connection mode has been granted to support the multi-connection function of the wireless mouse.
In some other embodiments, after receiving the notification that the wireless mouse is currently in the multi-connection mode, both the second device and the third device may pop up a window for the user to choose whether to grant related permission of the wireless mouse in the multi-connection mode to support the multi-connection function of the wireless mouse.
In a possible example, as shown in
S904: The first device sends migration indication information to the wireless mouse when detecting that the mouse cursor tends to slide to another device.
The migration indication information indicates to perform focus migration of the wireless mouse.
In some embodiments, the migration indication information includes information about a position at which the mouse cursor slides out of the display of the first device.
Optionally, the migration indication information further includes a size of the display of the first device.
In another possible implementation, the information about the position at which the mouse cursor slides out of the display of the first device may be alternatively sent by the first device to the wireless mouse independently. This is not limited in this application.
Optionally, the first device may further independently send the size of the display of the first device to the wireless mouse.
In some embodiments, that the first device detects that the mouse cursor tends to slide to another device means that the first device detects that the mouse cursor slides out of the edge of the display of the first device, and a vector moving toward the another device exceeds a preset threshold. For example, the first device may monitor a position of the mouse cursor in real time. After the first device detects that the mouse cursor slides out of the edge of the display of the first device, the first device can still continuously receive a message sent by the wireless mouse, where movement coordinates of the mouse cursor moving toward the another device exceed the preset threshold. The another device is the target host.
In some embodiments, the migration indication information does not include related information of the target host. In this case, the wireless mouse determines the target host. A specific method for determining the target host by the wireless mouse is specifically described in the following description of S905.
In some embodiments, the migration indication information indicates the target host (for example, the second device), that is, the migration indication information indicates the focus of the wireless mouse to migrate to the second device. For example, the migration indication information may carry identification information of the second device.
In some embodiments, the first device may determine the target host (for example, the second device) based on the information about the position at which the mouse cursor slides out of the display of the first device and multi-device connection configuration information of the wireless mouse.
Optionally, in some embodiments, the first device may determine the target host (for example, the second device) based on the information about the position at which the mouse cursor slides out of the display of the first device, the size of the display of the first device, and the multi-device connection configuration information of the wireless mouse.
In this embodiment of this application, the multi-device connection configuration information of the wireless mouse may include a working mode of the wireless mouse, and position sorting among the first device, the second device, and the third device that are currently connected to the wireless mouse. The position sorting among the first device, the second device, and the third device is used by the wireless mouse to determine the target host during focus migration. For example, if the first device is on a left side of the second device, when the mouse cursor slides out of a right edge of the display of the first device, and a moving vector exceeds the preset threshold, the wireless mouse may determine that the second device is the target host.
For example, the first device may determine the multi-device connection configuration information based on a manner 1 or a manner 2 (for details, refer to
Manner 1: The first device determines the multi-device connection configuration information based on a modification performed by the user on the multi-device connection configuration.
In a possible implementation, after the wireless mouse establishes the wireless communication connections to the second device and the third device, the first device may display a multi-device connection configuration interface shown in
As shown in
Further, as shown in
The migration indication information shown in
In this embodiment of this application, the modification performed by the user on the multi-device connection configuration may include but is not limited to: modifying position sorting between terminal devices, disabling a terminal device, deleting a terminal device, enabling a terminal device, adding a terminal device, and the like. This is not limited in this application. Disabling a terminal device means that the input device is not supported in performing focus migration to the terminal device. However, disabling a terminal device does not disconnect a wireless connection between the input device and the terminal device. Deleting a terminal device means disconnecting a wireless connection between the input device and a terminal device. In some embodiments, if a terminal device is deleted, an icon of the terminal device may be further deleted from the UI interface. Enabling a terminal device means resuming support for focus migration to the terminal device. For example, the enabled terminal device may be a terminal device that is disabled previously. Adding a terminal device means establishing a wireless connection to a terminal device. In some embodiments, if a terminal device is added, an icon of the terminal device may be further added to the UI interface. For example, the added terminal device may be a terminal device that is deleted previously.

Manner 2: The first device determines the multi-device connection configuration information of the wireless mouse based on a preset principle, a basis, a method, or the like.
In a possible implementation, the first device or the wireless mouse may obtain, based on an automatic positioning technology (for example, an ultrasonic positioning technology), the multi-device connection configuration information of the wireless mouse, for example, specific positions of the first device, the second device, and the third device that are currently connected to the wireless mouse in an environment, and then determine position sorting among the first device, the second device, and the third device based on the specific positions.
As shown in
For example, the first device may transmit an ultrasonic signal through a loudspeaker disposed in the first device, and receive an echo signal of an ultrasonic signal from a terminal device (for example, a second terminal and a third terminal) through a microphone disposed in the first device. Further, the first device determines, based on a triangular positioning technology, specific positions of a plurality of terminal devices (for example, the first device, the second device, and the third device) in an environment based on a transmission path for sending a signal, a transmission path for receiving a signal, and a relative position relationship between the speaker and the microphone, so as to determine position sorting among the plurality of terminal devices (for example, the first device, the second device, and the third device).
For a specific description of the automatic positioning technology (for example, the ultrasonic positioning technology), refer to descriptions in a conventional technology. Details are not described in this embodiment of this application.
Further, as shown in
The migration indication information shown in
S905: The wireless mouse switches the focus device to the second device.
In some embodiments, if the migration indication information indicates the wireless mouse to migrate to the second device, for example, if the migration indication information carries the identification information of the second device, S905 may specifically include: The wireless mouse switches the focus device to the second device based on the identification information of the second device that is carried in the migration indication information.
In some other embodiments, if the migration indication information does not indicate the target host of the wireless mouse, S905 may specifically include: The wireless mouse determines the target host (for example, the second device) based on the information about the position at which the mouse cursor slides out of the display of the first device and the multi-device connection configuration information of the wireless mouse. The information about the position at which the mouse cursor slides out of the display of the first device is from the migration indication information.
For example, the wireless mouse may obtain the multi-device connection configuration information of the wireless mouse based on a manner A or a manner B.
Manner A: The wireless mouse determines the multi-device connection configuration information of the wireless mouse based on a preset principle, a basis, a method, or the like (for details, refer to
In a possible implementation, as shown in
For example, the wireless mouse may transmit an ultrasonic signal by using a first component disposed in the wireless mouse, receive an echo signal of an ultrasonic signal from a terminal device (for example, a first terminal, a second terminal, and a third terminal) by using a second component disposed in the wireless mouse, and determine specific positions of a plurality of terminal devices (for example, the first device, the second device, and the third device) in an environment based on a transmission path for sending a signal, a transmission path for receiving a signal, and a relative position relationship between the first component and the second component, so as to determine the multi-device connection configuration information of the wireless mouse, for example, position sorting among the plurality of terminal devices (for example, the first device, the second device, and the third device).
As shown in
Further, as shown in
Manner B: The wireless mouse obtains the multi-device connection configuration information of the wireless mouse from the first device.
The multi-device connection configuration information of the wireless mouse that is obtained by the wireless mouse from the first device may be determined by the first device based on the foregoing manner 1 and the modification of the multi-device connection configuration by the user, or may be determined by the first device based on the foregoing manner 2 and a preset principle, a basis, or a method (for example, the ultrasonic positioning technology). This is not limited in this application.
For example, the multi-device connection configuration information of the wireless mouse may be sent by the first device to the wireless mouse before the wireless mouse switches the focus device from the first device to another terminal device.
Further, in some embodiments, to implement an effect of seamless continuation of the mouse cursor across devices, the first device may further synchronize, to the second device by using the wireless mouse, the information about the position at which the mouse cursor slides out of the display of the first device, as shown in S906 below. In an example, the wireless mouse may obtain, from the migration indication information that is from the first device, the information about the position at which the mouse cursor slides out of the display of the first device.
Optionally, the first device may further synchronize the size of the display of the first device to the second device by using the wireless mouse. For example, the first device may carry the size of the display of the first device by using the migration indication information, or separately send the size of the display of the first device to the wireless mouse.
S906: The wireless mouse sends, to the second device, the information about the position at which the mouse cursor slides out of the display of the first device.
The wireless mouse sends, to the second device, the information about the position at which the mouse cursor slides out of the display of the first device, so that the second device can determine an initial position of the mouse cursor on the display of the second device based on the position information, to continue the first device to display the mouse cursor, thereby implementing an effect of seamless continuation of the mouse cursor across devices.
S907: The second device displays the mouse cursor based on the information about a position at which the mouse cursor slides out of the display of the first device and the size of the display of the second device.
In an example, the second device may determine the initial position of the mouse cursor on the display of the second device based on the information about the position at which the mouse cursor sliding out of the display of the first device and the size of the display of the second device, and display the mouse cursor at the initial position.
In an example, when determining the initial position of the mouse cursor on the display of the second device, the second device may consider a time (for example, a preset time or an actual measurement time) spent in communication between devices, to compensate for a display lag.
S908: The wireless mouse receives the first operation of the user, and sends the movement information of the mouse cursor to the second device.
The first operation is, for example, an operation of moving the wireless mouse.
It may be understood that, based on the input device connection method provided in this embodiment of this application, an input device may randomly perform focus migration between a plurality of terminal devices. In this method, operation steps of simultaneously using the plurality of terminal devices can be simplified. In addition, according to the method provided in this embodiment of this application, an input device may simultaneously maintain communication connections to a plurality of terminal devices, and exchange information with a non-focus device in a background based on a communication connection between the input device and the non-focus device, to implement seamless focus migration between the plurality of terminal devices, ensure that no interface display freezing occurs during switching, and implement an effect of seamless continuation of the input device across devices. In addition, according to this method, information synchronization does not need to rely on a WLAN, that is, the plurality of terminal devices do not need to connect to a same WLAN.
In some embodiments, the wireless device (for example, the first input device) in this embodiment of this application further has a function of collaborative migration with another wireless device (for example, the second input device). For example, when the second input device switches the focus device from the first device to the second device, the first input device may synchronously switch the focus device from the first device to the second device. For another example, the second input device may alternatively switch the focus device from the first device to the second device after the first input device switches the focus device from the first device to the second device. According to the method, synchronous cross-device seamless focus migration between the first input device and the second input device can be implemented.
In a possible implementation, when the first input device switches the focus device to the second device, the first device may send a synchronous focus device switching instruction to the second input device that establishes a wireless connection to the source host, where the synchronous focus device switching instruction carries information about a target host (for example, the second device), to instruct the second input device to synchronously switch the focus device to the second device.
The following uses an example shown in
Then, after the user enables a multi-device connection function of the wireless mouse, the wireless mouse enters the multi-connection mode from the normal mode. As shown in
S1703: The first device sends a working mode switching instruction to the wireless mouse when receiving a second operation performed by the user on the UI interface.
The UI interface is, for example, a UI interface used to manage a multi-connection mode related configuration or operation. The second operation is, for example, an operation of enabling the multi-device connection function of the wireless mouse. The working mode switching instruction instructs the wireless mouse to switch to the multi-connection mode, for example, switch from the common mode to the multi-connection mode.
S1704: The wireless mouse establishes wireless communication connections to the second device and the third device.
After the wireless mouse receives the working mode switching instruction from the first device, the wireless mouse enters the multi-connection mode, and establishes wireless communication connections to the second device and the third device. After the wireless mouse enters the multi-connection mode and establishes the wireless communication connections to the second device and the third device, the first device is a focus device of the wireless mouse, and the second device and the third device are non-focus devices of the wireless mouse. In other words, the wireless mouse may directly control the first device currently.
S1705: The first device obtains identification information of the second device and identification information of the third device from the wireless mouse.
For example, after establishing the wireless communication connections to the second device and the third device, the wireless mouse may store the identification information of the second device and the identification information of the third device (for example, stored in a pairing information list). Further, after the wireless mouse establishes the wireless communication connections to the second device and the third device, the wireless mouse may share the identification information of the second device and the identification information of the third device with the first device.
For example, the identification information of the second device is, for example, the last four bits of a MAC address of the second device, and the identification information of the third device is, for example, the last four bits of a MAC address of the third device.
S1706. When receiving a fifth operation of the user, the first device sends a synchronous working mode switching instruction to the wireless keyboard.
The fifth operation is an operation of enabling a keyboard and mouse collaboration function. The synchronous working mode switching instruction instructs the wireless keyboard to switch to the multi-connection mode, for example, switch from the common mode to the multi-connection mode.
In an example, the synchronous working mode switching instruction may carry the identification information of the second device and the identification information of the third device, so that the wireless keyboard establishes wireless communication connections to the second device and the third device based on the identification information.
In an example, the first device may provide an option used by the user to select the keyboard and mouse collaboration function, so that the user performs setting based on an actual requirement. For example, an operation of enabling the keyboard and mouse collaboration function by the user is an operation of enabling a keyboard and mouse collaboration switch (402 shown in
S1707: The wireless keyboard establishes wireless communication connections to the second device and the third device.
After the wireless keyboard receives the synchronous working mode switching instruction from the first device, the wireless keyboard enters the multi-connection mode, and establishes the wireless communication connections to the second device and the third device. After the wireless keyboard enters the multi-connection mode and establishes the wireless communication connections to the second device and the third device, the first device is a focus device of the wireless keyboard, and the second device and the third device are non-focus devices of the wireless keyboard. In other words, the wireless keyboard may directly input information to the first device currently.
In a possible implementation, the wireless keyboard may establish the wireless communication connection to the second device through a third MAC address and perform subsequent communication, and establish the wireless communication connection to the third device through a fourth MAC address and perform subsequent communication.
In an example, the wireless keyboard may determine, by comparing information about the paired terminal device in the Bluetooth channel with the identification information carried in the synchronous working mode switching instruction, whether the wireless keyboard has been paired with the second device and the third device. For example, if the wireless keyboard has not been paired with the second device or the third device, the wireless keyboard may initiate a pairing request based on the identification information carried in the synchronous working mode switching instruction.
In an example, for a process in which the wireless keyboard establishes the wireless communication connections to the second device and the third device, refer to a process in which the wireless mouse establishes the wireless communication connections to the second device and the third device shown in
In an example, as shown in
S1708: When detecting that the mouse cursor tends to slide to another device, the first device sends migration indication information to the wireless mouse, and sends collaborative migration indication information to the wireless keyboard.
The migration indication information indicates to perform focus migration of the wireless mouse.
In some embodiments, the migration indication information includes information about a position at which the mouse cursor slides out of the display of the first device.
In another possible implementation, the information about the position at which the mouse cursor slides out of the display of the first device may be alternatively sent by the first device to the wireless mouse independently. This is not limited in this application. In some embodiments, the migration indication information indicates the target host (for example, the second device), that is, the migration indication information indicates the focus of the wireless mouse to switch the focus device to the second device. For example, the migration indication information may carry identification information of the second device.
In some embodiments, the first device may determine the target host (for example, the second device) based on the information about the position at which the mouse cursor slides out of the display of the first device and multi-device connection configuration information of the wireless mouse. For example, the first device may determine the multi-device connection configuration information based on the foregoing manner 1 or manner 2.
S1709: The wireless mouse switches the focus device to the second device.
In some embodiments, if the migration indication information indicates the wireless mouse to switch the focus device to the second device, for example, if the migration indication information carries the identification information of the second device, S1709 may specifically include: The wireless mouse switches the focus device to the second device based on the identification information of the second device that is carried in the migration indication information.
In some other embodiments, if the migration indication information does not indicate the target host of the wireless mouse, S1709 may specifically include: The wireless mouse determines the target host (for example, the second device) based on the information about the position at which the mouse cursor slides out of the display of the first device and the multi-device connection configuration information of the wireless mouse. In an example, the information about the position at which the mouse cursor slides out of the display of the first device is from the migration indication information. For example, the wireless mouse may obtain the multi-device connection configuration information of the wireless mouse based on the foregoing manner A or manner B.
S1710: The wireless keyboard switches the focus device to the second device.
As shown in
Further, in some embodiments, to keep synchronization of multi-device connection configuration information of the wireless mouse between the target host and the source host, the first device may further synchronize the multi-device connection configuration information of the wireless mouse to the second device by using the wireless mouse, for continued input from the input device to the second device, as shown in the following S1711 to S1714.
S1711: The wireless mouse sends, to the second device, the information about the position at which the mouse cursor slides out of the display of the first device.
S1712: The second device displays the mouse cursor based on the information about a position at which the mouse cursor slides out of the display of the first device and the size of the display of the second device.

The fourth operation is an operation of inputting information into the input box in which the mouse cursor is located.
For specific processes of steps S1701, S1704, S1707, S1708, S1709, S1711, S1712, and S1713 shown in
It may be understood that, based on the input device connection method provided in this embodiment of this application, a plurality of input devices may perform collaborative migration. For example, when the first input device switches the focus device from the first device to the second device, the second input device synchronously switches the focus device from the first device to the second device. This method can greatly simplify an operation step of simultaneously using a plurality of terminal devices by the user, to implement seamless and synchronous migration of a plurality of input devices between the plurality of terminal devices, ensure that no interface display freezing occurs during switching, and implement an effect of seamless continuation of the plurality of input devices across devices. In addition, according to this method, information synchronization does not need to rely on a WLAN, that is, the plurality of terminal devices do not need to connect to a same WLAN.
Further, to ensure that the second device can synchronize a related personalized configuration parameter like a cursor display parameter of the first device after the input device switches the focus device from the first device to the second device, so as to implement seamless migration. In some embodiments, the input device (for example, the wireless mouse and/or the wireless keyboard) may further send the personalized configuration parameter of the input device to the second device. The personalized configuration parameter of the input device may include but is not limited to one or more of the following: dots per inch (dot per inch, DPI), a key definition (for example, shortcut key settings and a main key definition), and fingerprint information.
In some embodiments, the personalized configuration parameter of the input device may be sent by the first device to the input device before the input device switches the focus device from the first device to another terminal device. In an example, the first device may send the personalized configuration parameter of the input device to the input device based on setting performed by the user on a setting interface (an interface shown in
A keyboard and mouse collaboration scenario is used as an example. In an example, as shown in S1709′ and S1710′ in
It may be understood that, the personalized configuration parameter of the input device is synchronized between the terminal devices, so that a consistent effect of personalized display effects (such as a size of a cursor, a shape of the cursor, a color of the cursor, DPI, and a display effect corresponding to a key) of the input device before and after the focus device is switched can be implemented, thereby providing the user with smoother input device migration experience.
