[0048] The present disclosure will now be described more specifically with reference to the following embodiments. It should be noted that the following description of some embodiments presented in this specification is for illustrative and descriptive purposes only. It is not exhaustive or limited to the exact forms disclosed.

[0049] In a first aspect, the present disclosure provides a method for shuttling (moving) a mouse cursor between a server device and a client device executed on the server device side. Figure 1 is a flowchart of a method for shuttling a mouse cursor between the server device and the client device executed on the server device side according to an embodiment of the present disclosure. As Figure 1As shown, the method includes the following steps:

[0050] S1 A connection request is initiated by one of at least one client device to the server device or by the server device to the client device to establish a connection between the client device and the server device;

[0051] S2 A connection between the server device and the client device is established according to the connection request;

[0052] S3 Determine the logical relative position relationship between the server device and the client device; wherein, the display of the server device includes at least one edge (which can also be referred to as a side or a border), and each edge is logically occupied by a client device and serves as the boundary for the mouse cursor to shuttle between the server device and this client device; different edges are occupied by different client devices;

[0053] S4 By controlling the mouse connected to the server device, the mouse cursor is shuttled between the server device and the client device.

[0054] In some embodiments of the present disclosure, the mouse cursor is shuttled between the server device and the client device by moving the mouse of the server device to reach and move away from the edge corresponding to the client device.

[0055] Figure 2 It is a schematic diagram of the connection between the server device and the client device according to an embodiment of the present disclosure.

[0056] In some embodiments of the present disclosure, a connection is established between the server device and the client device through a network (such as the Internet, local area network, wide area network, etc.). In some embodiments of the present disclosure, a connection is established between the server device and the client device in a wired or wireless form.

[0057] In some embodiments of the present disclosure, a client device supporting multiple forms and multiple operating systems is connected to a server device. The server device may be a desktop, an all-in-one computer, a laptop, or a tablet computer. The server device may be a device connected to an operable real mouse. The client device may be a desktop, an all-in-one computer, a laptop, a tablet computer, an Android all-in-one machine, or an Android large-size device. The operating system of the server device may be Huawei Hongmeng system, Microsoft Windows, macOS, Linux, Google Chrome OS, iOS, Android, kaios, ipad OS, fuchsia OS. The operating system of the client device may be Huawei Hongmeng system, Microsoft Windows, macOS, Linux, Google Chrome OS, iOS, Android, kaios, ipad OS, fuchsia OS.

[0058] In some embodiments of the present disclosure, the server device is connected to a real mouse and can receive and process all mouse operations, including movement, left-key events, right-key events, or wheel scrolling, etc. These operations can also be called physical operations of the mouse. The server device determines all mouse cursor operations based on the connection status of the client device and the movement range of the mouse cursor.

[0059] As known to those skilled in the art, the mouse also includes a multi-button mouse, such as a two-button mouse, a three-button mouse for AutoCAD software, and a five-button mouse commonly used in electronic games, etc. In some embodiments of the present disclosure, the server device can be connected to the above-mentioned various types of mice, and perform all operations of the connected mouse to realize all functions of the connected mouse.

[0060] In some embodiments of the present disclosure, a request for connection between a client device and a server device is initiated by the client device to the server device. Specifically, a connection request can be initiated on the client device side using a remote control or a touch screen, or by operating a mouse on the client device side. For example, when a conference screen is projected, a participant uses a mouse to operate his or her computer offstage to initiate a connection request, and then goes to the stage to speak after the connection between the client device and the server device is established. Alternatively, in other embodiments, an application can be automatically run when the client device is turned on, and a connection request is initiated by the server device to the client device. The connection is confirmed by the client device, and the confirmation result is fed back to the server device, and then the server device directly establishes a connection between the client device and the server device.

[0061] In some embodiments of the present disclosure, step S2 of establishing a connection between the server device and the client device includes the following steps:

[0062] S21 Determine whether the number of client devices already connected to the server device has reached the maximum value;

[0063] If the number of client devices already connected to the server device has not reached the maximum value, then S22 Establish a connection between the server device and the client device and notify the client device that the connection is successfully established.

[0064] If the number of client devices already connected to the server device has reached the maximum value, then a connection cannot be established with this client device. At the same time, the server device notifies the client device that the connection establishment fails, and the client device receives the notification of the connection establishment failure and stops running the relevant application program.

[0065] In some embodiments of the present disclosure, step S3 of determining the logical relative position relationship between the server device and the client device includes the following steps:

[0066] S31 Receive the display resolution and position request of the client device; wherein, the position request is: the request of the client device for the edge of the display of the server device that it expects to occupy;

[0067] S32 Determine whether the edge that the client device requests to occupy is already occupied by other client devices;

[0068] If the edge that the client device requests to occupy is already occupied by other client devices, then S34 Automatically allocate an unoccupied edge for the client device; if the edge that the client device requests to occupy is not occupied by other client devices, then S35 Allocate the edge that the client device requests to occupy according to the position request from the client device. The server device will save the information of the client device for subsequent use of the mouse cursor to shuttle.

[0069] In some embodiments of the present disclosure, the display of the server device includes multiple edges. Generally, since the display is rectangular, the display of the server device includes four edges. The number of client devices simultaneously connected to the server device is limited, and this number does not exceed the number of edges of the display of the server device. However, the present disclosure is not limited thereto, and other ways can also be used to limit the number of client devices simultaneously connected to the server device. For example, one edge corresponds to two client devices, and each client device corresponds to a part of an edge. For example, the upper half of the right edge corresponds to one client device, and the lower half corresponds to another client device. In the present disclosure, the example where the number of client devices simultaneously connected to the server device does not exceed the number of edges of the display of the server device is used for description.

[0070] In some embodiments of the present disclosure, each edge is logically occupied by one client device, and different edges are logically occupied by different client devices, which means that each client device corresponds to one edge, and different client devices correspond to different edges. For each client device, the server device only provides one edge of the display. This edge is used as the boundary for the mouse cursor to shuttle between the server device and the corresponding client device to represent the relative position between the server device and the corresponding client device.

[0071] In some embodiments of the present disclosure, the server device needs to determine the logical relative position relationship with the client device. In the present disclosure, preferably, the edge positions of the display of the server device (i.e., the upper, lower, left, and right edge positions of the display of the server device) are used as the relative position with the client device, and at the same time, this relative position is used as the boundary for the mouse cursor to shuttle in and out. That is, the corresponding edge of the display of the server device is used as the boundary for the mouse cursor to shuttle (from the server device into the client device and from the client device into the server device). The server device receives the movement event of the real mouse connected to the server device. After the server device determines that the mouse cursor moves to the edge of the display of the server device, if the mouse cursor continues to move outwards, the mouse cursor shuttle starts, the mouse cursor disappears on the display of the server device, and appears on the display of the client device.

[0072] Common displays usually only have four edges, namely, upper, lower, left, and right. In one embodiment, the server device can be simultaneously connected to a maximum of 4 client devices. In the present disclosure, the example where the display has four edges, namely, upper, lower, left, and right, is used for description.

[0073] Such as Figure 2As shown, a server device SE includes four edges R1 to R4 (i.e., the four edges R1 to R4 of the display screen of the server device SE), corresponding to four client devices CL1 to CL4 connected to the server device SE respectively. The server device SE further includes a central area MA, which is used to position the mouse cursor originally at the server device SE at a position within the central area MA when the mouse cursor shuttles to the display of any client device. When the mouse cursor passes through edge R1, the mouse cursor will shuttle to the display of the corresponding client device CL1, that is, edge R1 is logically occupied by client device CL1. Similarly, when the mouse cursor passes through edge R2, the mouse cursor will shuttle to the display of the corresponding client device CL2, that is, edge R2 is logically occupied by client device CL2. When the mouse cursor passes through edge R3, the mouse cursor will shuttle to the display of the corresponding client device CL3, that is, edge R3 is logically occupied by client device CL3. When the mouse cursor passes through edge R4, the mouse cursor will shuttle to the display of the corresponding client device CL4, that is, edge R4 is logically occupied by client device CL4.

[0074] For the relative position relationship between the client device and the server device, it can be automatically assigned by the server device according to the current connection situation, or the client device can apply actively.

[0075] In one embodiment, for the case where there are more than 4 client devices, the connection between the client devices that do not need to be operated temporarily and the server device can be disconnected, and only the client devices that need to be operated are connected to the server device. When no client device is connected to the server device, all mouse operations take effect on the server device.

[0076] For example, there are more than five client devices that need to be operated, and the server device can connect to at most four client devices, that is, the number of client devices already connected to the server device has exceeded the maximum value. When the fifth or sixth client device needs to be operated, just disconnect the connection between one or several of the already connected client devices and the server device, and connect the client device to be operated to the server device. In the above situation, the user can select the relative position relationship between the client device to be replaced and the server device; alternatively, since the server device stores information about the previously connected client devices, when a previously connected client device is connected to the server device again, the relative position relationship between the client device and the server device is preferentially maintained as the relative position relationship during the previous connection, and at the same time, a position is automatically assigned to the newly connected client device.

[0077] In some embodiments of the present disclosure, shuttling the mouse cursor between the server device and the client device includes: moving the mouse cursor from the server device to the client device and moving the mouse cursor from the client device to the server device.

[0078] Figure 3 FIG. is a flowchart of a method for moving a mouse cursor from a server device to a client device according to an embodiment of the present disclosure. In some embodiments of the present disclosure, as Figure 3 shown, for a client device that corresponds to any edge and has established a connection with the server device, moving the mouse cursor from the server device to the client device includes the following steps:

[0079] S01 Obtain the coordinate value (first coordinate value) of the mouse cursor currently displayed on the display of the server device;

[0080] S02 Determine whether a cursor departure flag exists. The cursor departure flag indicates that the mouse is no longer used to implement operations on the server device, but the mouse cursor has shuttled to the client device to implement operations on the client device. It should be noted that regardless of whether the mouse cursor is displayed on the client device to implement operations on the client device or on the server device to implement operations on the server device, the physical operation of the mouse is performed at the server device by the user at the server device. In one embodiment, the cursor departure flag may be, for example, a specific pattern at a specific position (such as on the edge), such as a circle, a hollow circle, a star, etc. The specific edge may indicate that the physical operation of the mouse is implementing operations on its corresponding client device.

[0081] If the cursor departure flag does not exist at the server device, that is, it indicates that the mouse cursor is still on the display of the server device at this time, then execute S03: Determine whether the mouse cursor has reached the edge of the display of the server device occupied by the client device;

[0082] If the mouse cursor has not reached the edge of the display of the server device occupied by the client device, then do not perform the mouse cursor shuttle, as Figure 3 shown in step S032.

[0083] If the mouse cursor has reached the edge of the display of the server device occupied by the client device, then perform step S04, including:

[0084] S041 According to the display resolution of the client device, convert the coordinate value of the mouse cursor displayed on the display of the server device into the initial coordinate value to be displayed on the display of the client device, record the initial coordinate value, and send the initial coordinate value to the client device to display the mouse cursor at the corresponding position on the display of the client device according to the initial coordinate value;

[0085] S042 hides the mouse cursor displayed on the display of the server device. At this time, the hidden mouse cursor is located within the central area of the display of the server device, as Figure 2 shown in the central area MA. In some embodiments of the present disclosure, the hidden cursor is located at a position (e.g., the first position) within the central area of the display of the server device.

[0086] Figure 2 The central area MA shown is rectangular, and it can also be other shapes, such as a square, a circle, an ellipse, a rhombus, etc. that occupy the central position of the display of the server device. As long as the hidden mouse cursor on the display of the server device is located at a relatively central position of the display of the server device to provide sufficient space for the movement of the mouse cursor. Preferably, the hidden mouse cursor on the display of the server device is located at the central position of the display screen of the server device. At this time, the coordinate value of the mouse cursor at the server device is the central coordinate value.

[0087] S043 displays a cursor departure flag, and this cursor departure flag indicates that the mouse cursor is not displayed on the display of the server device, and the mouse cursor is displayed on the display of the client device;

[0088] If the cursor departure flag exists at the server device, it means that the current mouse cursor has shuttled to the client device, then execute S05: Convert the coordinate value of the mouse cursor at the server device into the coordinate value (the second coordinate value) of the mouse cursor displayed on the display of the client device, record this coordinate value, and send this coordinate value to the client device to display the mouse cursor at the corresponding position on the display of the client device according to this coordinate value.

[0089] In some embodiments of the present disclosure, the existence of the cursor departure flag at the server device means that the current mouse cursor has shuttled to the client. At this time, it is necessary to convert the coordinates of the mouse cursor of the server device into the coordinates of the mouse cursor to be displayed on the client device, and send the converted coordinate value to the client device for display.

[0090] In some embodiments of the present disclosure, step S05, converting the coordinate value of the mouse cursor at the server device into the coordinate value of the mouse cursor displayed on the display of the client device, recording this coordinate value, and sending this coordinate value to the client device to display the mouse cursor at the corresponding position on the display of the client device according to this coordinate value, includes:

[0091] When the mouse cursor at the server device has been hidden and is located within the central area of the display of the server device, move the mouse of the server device to obtain new coordinate values of the mouse cursor at the server device;

[0092] S052 Calculate the difference between the new coordinate values and the coordinates of the first position where the hidden mouse cursor is located within the central area of the display of the server device, and obtain the coordinate values of the mouse cursor newly displayed on the display of the client device based on this difference;

[0093] S053 Record the coordinate values of the mouse cursor newly displayed on the display of the client device, and send these coordinate values to the client device to display the mouse cursor at the corresponding position on the display of the client device according to these coordinate values;

[0094] S054 Return the mouse cursor at the server device to the first position within the central area of the display.

[0095] In the embodiments of the present disclosure, each step may be executed sequentially in the order shown in the drawings, may be executed in parallel, or may be executed in the reverse order of the order shown in the drawings. The present disclosure does not make any limitations in this regard.

[0096] As an example, the right edge of the display of the server device is used as the boundary for the mouse cursor to shuttle between the client device connected to the server device and the server device; the resolution of the display of the server device is: 3840×2160; the resolution of the display of the client device is: 1920×1080. Under the above conditions, the following exemplary description is made.

[0097] Combined with Figures 1 to 3 , the server device has established a connection with a client device, and the right edge of the display of the server device is the boundary for the mouse cursor to shuttle. Moving the mouse cursor from the server device to the client device includes the following steps:

[0098] S01 Obtain the coordinate values (first coordinate values) of the mouse cursor currently displayed on the display of the server device;

[0099] S02 Determine whether the cursor departure flag exists;

[0100] If the cursor departure flag of the server device does not exist, then execute S03: Determine whether the cursor reaches the edge of the display of the server device occupied by the client device, that is, the boundary where the mouse cursor shuttles between the server device and the client device, which is to determine whether the mouse cursor reaches the right edge of the display of the server device. For example, when the mouse cursor reaches the right edge of the display of the server device, the abscissa of the mouse cursor is x = 3840; if x < 3840, that is, it does not reach the right edge, all the movement and click events of the mouse cursor are processed on the server device, and there is no need for the mouse cursor to shuttle; if the mouse cursor has reached the right edge of the display of the server device, that is, x = 3840, it means that the mouse cursor of the server device will shuttle to the client device;

[0101] If the mouse cursor does not reach the edge of the display of the server device occupied by the client device, then the mouse cursor shuttle is not executed.

[0102] If the mouse cursor has reached the right edge of the display of the server device, then perform step S04, including:

[0103] S041 According to the display resolution of the client device, convert the coordinate value of the mouse cursor displayed on the display of the server device into the initial coordinate value displayed on the display of the client device, record the initial coordinate value, and send the initial coordinate value to the client device to display the mouse cursor at the corresponding position on the display of the client device according to the initial coordinate value;

[0104] S042 Hide the mouse cursor displayed on the display of the server device, where the hidden mouse cursor is located at, for example, the center position of the display of the server device, and the coordinate value of the hidden mouse cursor is the center coordinate value; the center coordinate value of the mouse cursor is: (1920, 1080);

[0105] S043 Display the cursor departure flag, which indicates that the mouse cursor is not displayed on the display of the server device and the mouse cursor is displayed on the display of the client device.

[0106] In an embodiment of the present disclosure, the client device corresponds to the right edge of the display of the server device. It can be considered that the client device is on the right side of the server device. That is, when the mouse cursor crosses the right edge of the display of the server device and enters the client device, it first appears at the left edge of the display of the client device. Therefore, the abscissa x of the initial coordinate value displayed on the display of the client device is 0. Therefore, it is only necessary to calculate the ordinate y of the initial coordinate value displayed on the display of the client device, and the calculation method is as follows: y = the ordinate of the coordinate value of the mouse cursor currently displayed on the display of the server device × (the height value of the resolution of the display of the client device / the height value of the resolution of the display of the server device).

[0107] Assume that the coordinate of the mouse cursor of the server device at this time is (3840, 1080). According to the above formula, the ordinate y of the initial coordinate value displayed on the display of the client device is:

[0108] y = 1080 × (1080 / 2160) = 540;

[0109] That is, the initial coordinate value displayed on the display of the client device is (0, 540).

[0110] If the cursor departure flag of the server device exists, then execute S05: Convert the coordinate value of the mouse cursor at the server device into the coordinate value of the mouse cursor displayed on the display of the client device (the second coordinate value), record the coordinate value, and send the coordinate value to the client device to display the mouse cursor at the corresponding position on the display of the client device according to the coordinate value.

[0111] Specifically, step S05 includes: When the mouse cursor at the server device has been hidden and it is moved to the center position of the display of the server device, that is, when the coordinate value of the mouse cursor at the server device is (1920, 1080), move the mouse of the server device to obtain a new coordinate value of the mouse cursor at the server device, such as (1921, 1081);

[0112] Alternatively, in other embodiments of the present disclosure, after the mouse cursor shuttles from the server device to the client device, the mouse cursor at the server device may not be hidden. However, preferably, the mouse cursor at the server device is hidden after the mouse cursor shuttles from the server device to the client device to prevent the user from mistakenly operating because they think the mouse cursor has not shuttled to the client device.

[0113] S052 calculates the difference between the new coordinate value and the center coordinate value, e.g., (1, 1), and adds this difference (1, 1) to the initial coordinate value (0, 540) displayed on the display of the client device, obtaining the new coordinate value (1, 541) of the mouse cursor displayed on the display of the client device;

[0114] S053 records the coordinate value of the new mouse cursor displayed on the display of the client device, and sends this coordinate value to the client device to display the mouse cursor at the corresponding position on the display of the client device according to this coordinate value;

[0115] S054 moves the mouse cursor at the server device to the center position of the display, i.e., the coordinate value of the mouse cursor at the server device is (1920, 1080). For each subsequent mouse movement, the difference between the new coordinate value of the mouse cursor at the server device and the center coordinate value is calculated, and this difference is added to the most recently recorded coordinate value of the mouse cursor displayed on the display of the client device as the new coordinate value of the mouse cursor displayed on the display of the client device, and this coordinate value is sent to the client device to display the mouse cursor at the corresponding position on the display of the client device according to this coordinate value. In this way, the movement of the mouse cursor on the display of the client device is achieved.

[0116] In the above manner, the effect of moving the mouse cursor from the server device to the client device and moving on the display of the client device is achieved.

[0117] In the embodiments of the present disclosure, the hiding of the mouse cursor can be achieved by calling the pre-set program code. In the embodiments of the present disclosure, when the mouse cursor has been displayed on the display of the client device, after each movement of the mouse, at the server device, the mouse cursor will return to the first position (e.g., the center position) within the central area of the display, which is also achieved by calling the pre-set program code.

[0118] Figure 4 is a flowchart for moving the mouse cursor from the client device to the server device according to an embodiment of the present disclosure. In some embodiments of the present disclosure, as Figure 4 shown, for a client device corresponding to any edge and having established a connection with the server device, moving the mouse cursor from the client device to the server device includes:

[0119] S001 moves the mouse of the server device,

[0120] S002 Obtain the coordinate value of the mouse cursor at the server device currently, calculate the coordinate value of the mouse cursor displayed on the display of the client device, and determine whether the obtained coordinate value of the mouse cursor displayed on the display of the client device is equal to the first threshold;

[0121] If the coordinate value is equal to the first threshold, then S003 clear the cursor departure flag, and calculate the coordinate value of the mouse cursor displayed on the display of the server device to display the mouse cursor on the server device, where the mouse cursor is close to the occupied edge of the display of the server device by the client device.

[0122] In some embodiments of the present disclosure, the mouse cursor moves to the display of the server device through the occupied edge of the display of the server device by the client device.

[0123] If the coordinate value is not equal to the first threshold, it indicates that the mouse cursor has not moved from the client device to the server device. At this time, the mouse cursor is still displayed on the display of the client device, as Figure 4 shown in S004.

[0124] In some embodiments of the present disclosure, there are no requirements for the resolution of the display of the server device and the resolution of the display of the client device. However, the resolution of the display of the server device is preferably greater than the resolution of the display of the client device to provide sufficient movement range for the mouse cursor displayed on the display of the client device.

[0125] For example, as shown in combination with Figures 1 to 4 a server device has established a connection with a client device, and the right edge of the display of the server device is the boundary for the mouse cursor to shuttle, enabling the mouse cursor to move from the client device to the server device, including the following steps:

[0126] S001 Move the mouse of the server device,

[0127] S002 Obtain the coordinate value of the mouse cursor at the server device currently, calculate the coordinate value of the mouse cursor displayed on the display of the client device, and determine whether the obtained coordinate value of the mouse cursor displayed on the display of the client device is equal to the first threshold; for example, the first threshold is usually the abscissa value of -1, and there is no requirement for the ordinate. Specifically, determining whether the obtained coordinate value of the mouse cursor displayed on the display of the client device is equal to the first threshold includes: determining whether the abscissa x of the coordinate value is equal to -1.

[0128] If x = -1, indicating that the mouse cursor needs to return to the server device at this time, then S003 clears the cursor departure flag and calculates the coordinate value of the mouse cursor displayed on the display of the server device to display the mouse cursor on the server device, where the mouse cursor is located at the edge occupied by the client device near the display of the server device.

[0129] If the coordinate value is not equal to -1, it indicates that the mouse cursor has not moved from the client device to the server device. At this time, the mouse cursor is still displayed on the display of the client device.

[0130] Since the shuttle boundary between the mouse cursor on the server device and the client device is the right edge of the display of the server device, when the mouse cursor returns to the server device, it should first appear at the rightmost side of the display of the server device. Therefore, the abscissa x is the maximum value of the resolution of the display of the server device, that is, x = 3840, and the ordinate y is calculated according to the coordinate value (specifically the ordinate value) of the mouse cursor displayed on the display of the client device when the mouse cursor is about to shuttle back to the server device. At this time, the ordinate y of the mouse cursor displayed on the display of the server device is calculated in the following way:

[0131] Assume that the coordinate value of the mouse cursor displayed on the display of the client device is (-1, 270). According to the display resolution of the server device and the display resolution of the client device, calculate the ordinate y = (the current ordinate value of the mouse cursor displayed on the display of the client device / the height value of the display resolution of the client device) × the height value of the display resolution of the server device;

[0132] That is, y = (270 / 1080) × 3840 = 960;

[0133] Finally, the coordinate value of the mouse cursor when it shuttles back to the server device and is initially displayed on the display of the server device is obtained as (3840, 960), that is, the mouse cursor should first appear at the position with the coordinate value (3840, 960) when it returns to the server device.

[0134] In the above example, the description is given by taking the right edge of the display of the server device as the boundary for the mouse cursor to shuttle between the client device connected to the server device and the server device. In a similar manner, the following methods for shuttling (moving) the mouse cursor between the server device and the client device can be obtained: taking the left edge of the display of the server device as the boundary for the mouse cursor to shuttle between the client device connected to the server device and the server device; taking the upper edge of the display of the server device as the boundary for the mouse cursor to shuttle between the client device connected to the server device and the server device; and taking the lower edge of the display of the server device as the boundary for the mouse cursor to shuttle between the client device connected to the server device and the server device. Details are not described herein.
