Since there is a certain network delay when the virtual machine sends the desktop image to the cloud desktop client, when the user operates the mouse of the cloud desktop client, there is a certain delay between the movement of the mouse and the movement of the cursor in the desktop image displayed by the cloud desktop application. This caused the problem of the cursor not following the hand. In order to avoid the problem of the cursor not following the hand, the cloud desktop client can store the cursor appearance of the virtual machine's operating system application, and display the cursor appearance based on the locally detected cursor position, and the virtual machine is sending data to the cloud desktop client. The cursor appearance is not included in the desktop image sent in real time. That is, the cloud desktop client locally handles the display of the cursor in the desktop image.

However, in the interface corresponding to some applications, the application will update the cursor appearance. For example, when the cursor moves to the drawing interface corresponding to the drawing software, the drawing software will change the cursor appearance from an arrow to a brush. When these applications run on the operating system of the virtual machine, they will also update the cursor appearance in the operating system. However, currently, the cloud desktop client can only display the locally stored cursor appearance, and cannot synchronize the application's updates to the cursor appearance, thus reducing the cost of the cursor appearance.

In the solution shown in this application, after the cloud desktop server receives the second cursor movement instruction sent by the cloud desktop client, if the second cursor movement instruction instructs the cursor to be moved to the interface of the target application, it can obtain the target application update. The second interface, if it is determined that the second interface includes the cursor appearance, and the cursor appearance is the first cursor appearance, indicating that the cloud desktop server has not updated the cursor appearance, it can send a message including the first cursor appearance to the cloud desktop client. A second cursor appearance update request is made, so that the cloud desktop client updates the cursor in the interface of the target application according to the second operation and the first cursor appearance. Since the cursor appearance previously applied by the cloud desktop client is the first cursor appearance, the cloud desktop client only updates the display position of the cursor in the target application according to the second cursor appearance update request, but does not update the cursor appearance. In this way, the cloud desktop client can synchronize the cursor appearance applied in the cloud desktop server in real time according to the second cursor appearance update request, which can improve the user's experience of using the cloud desktop.

In a possible implementation, the method further includes: receiving a second cursor movement instruction sent by the cloud desktop client, the second cursor movement instruction instructing to move the cursor in the interface of the target application; sending the second cursor movement instruction to Target application; obtain the updated second interface of the target application; if the second interface includes the first cursor appearance, do not send a cursor appearance update request to the cloud desktop client.

The following is an introduction to the method for the cloud desktop client to display desktop images, as well as the cloud desktop client and each functional module included in the cloud desktop client, in conjunction with Figures 3 and 4:

S1. The cloud desktop service sends the cursor appearance to the cloud desktop application.

During the initialization phase of the cloud desktop service, the cursor appearance of the default application in the operating system can be sent to the cloud desktop application through the network communication module, so that the cursor image module in the cloud desktop application determines whether the cursor in the cloud desktop client moves to the cloud desktop. When applying the interface (cloud desktop application interface), set the cursor appearance of the cloud desktop client to the cursor appearance sent by the cloud desktop service, that is, the cursor appearance applied by default in the operating system.

S2. The cloud desktop application sends the cursor position to the cloud desktop service.

The keyboard and mouse module in the cloud desktop application, when detecting that the cursor of the cloud desktop client reaches the cloud desktop application interface, the keyboard and mouse module will determine the relative position of the cursor in the cloud desktop application interface, and according to a fixed reporting cycle, set the cursor in the cloud desktop application interface. The relative position in the cloud desktop application interface is sent to the network communication module of the cloud desktop service through the network communication module.

S3, the cloud desktop service sends the cursor position to the operating system.

After receiving the relative position of the cursor in the cloud desktop application interface sent by the cloud desktop application, the network communication module of the cloud desktop service can send the relative position to the keyboard and mouse module in the cloud desktop service. The keyboard and mouse module calculates the relative position of the cursor in the desktop image of the operating system based on the relative position, and sends the calculated absolute position to the keyboard and mouse driver module. The keyboard and mouse driver module can send the absolute position to the event distribution module in the operating system.

S4. The operating system sends mouse events to the target application.

The event distribution module in the operating system can determine the target application corresponding to the absolute position of the cursor based on the absolute position of the cursor in the operating system, and send corresponding mouse events to the event processing module of the target application.

S5. The target application responds to mouse events.

Respond to mouse events through the event processing module.

S6. The target application updates the interface.

If the mouse event triggers the target application to update the image, the target application can send an image update request to the rendering engine module of the operating system through the image update module, where the image update request can include the updated image and the location of the updated image in the desktop image. Location. After receiving the image update request, the rendering engine module of the operating system can send the image update request to the display driver module of the cloud desktop service. The display driver of the cloud desktop service renders graphics based on image update requests.

S7, the cloud desktop service sends the updated image to the cloud desktop application.

The display module in the cloud desktop service can obtain the updated image rendered by the display driver module and send the updated image to the network communication module, which sends the image to the cloud desktop application.

S8. Cloud desktop application updates the desktop image.

After receiving the updated image, the network communication module of the cloud desktop application can send the updated image to the display module, and the desktop image display module included in the display module displays the updated image.

It should be noted that the image sent by the cloud desktop service to the cloud desktop application does not include the cursor image. Because in step S1, the cloud desktop client displays the cursor corresponding to the cloud desktop server in the desktop application interface. The cursor image included in the desktop image that users see in the cloud desktop application interface.

Change the appearance of the cursor in some applications running on the virtual machine's operating system. If the cursor moves to the corresponding drawing interface of the drawing software, the drawing software will change the appearance of the cursor from an arrow to a brush. Before your application changes the cursor appearance, you can send a cursor hide request to the operating system so that the operating system does not display the cursor. The application can then send an image update notification carrying the cursor image to the operating system through the image update module, so that the application can handle the display of the cursor in the application. However, the operating system cannot distinguish whether the image update notification is the image update notification corresponding to the cursor image. Therefore, if the operating system processes each image update notification sent by the application, and the cloud desktop service sends the corresponding updated image to the cloud desktop application, it will cause the cursor to be displayed repeatedly in the cloud desktop application, one for the cloud desktop The cursor image sent by the service is the cursor image displayed by the cloud desktop client, and the two cursor images are inconsistent, and the cursor image sent by the cloud desktop service may not match the cursor image.

Figure 5 is a flow chart of a method for updating a cursor provided by an embodiment of the present application. This method is applied in a cloud desktop system and can synchronize the cursor appearance (cursor image) displayed on the cloud desktop client and the cloud desktop server in the cloud desktop system. ), and can avoid the problem of the cursor not following the hand. Referring to Figure 5, the method includes:

The cloud desktop client can realize communication with the cloud desktop server by running the purpose application, for example, sending the user's cloud desktop information to the cloud desktop server. Operation instructions triggered by the client, receiving desktop images sent by the cloud desktop server, etc. The purpose application can be a cloud desktop application.

The first operation may be triggered by the user moving the mouse of the cloud desktop client. The first operation includes moving the cursor displayed on the cloud desktop client from outside the cloud desktop application interface (the interface of the cloud desktop application) to the cloud desktop application interface, such as As shown in Figure 6, the user moves the cursor displayed on the cloud desktop client from point A outside the cloud desktop application interface to point B within the cloud desktop application interface by moving the mouse. Or the first operation includes moving the cursor displayed on the cloud desktop client within the cloud desktop application interface. As shown in Figure 7, the user moves the mouse to move the cursor displayed on the cloud desktop client from C in the cloud desktop application interface. Move the point to point D in the cloud desktop application interface.

Step 502: The cloud desktop client sends a first cursor movement instruction to the cloud desktop server according to the first operation.

After performing the first operation, the user may trigger a cursor movement instruction in the cloud desktop application, where the cursor movement instruction triggered for the first operation may be called a first cursor movement instruction. The first cursor movement instruction may include the relative position of the cursor in the cloud desktop application interface.

It should be noted that when the user performs the first operation, the cloud desktop application may trigger the first cursor movement instruction after the cursor moves to the cloud desktop application interface. When the cursor moves outside the cloud desktop application interface, the cloud desktop client can display the cursor according to the cursor appearance of the cloud desktop client application. When the user controls the movement of the cursor on the cloud desktop application interface, the cloud desktop application can send a first cursor movement instruction to the cloud desktop server according to a set cycle, and each first cursor movement instruction includes the current location of the cursor in the cloud desktop. Relative position in the desktop application interface.

In addition, the cloud desktop client can pre-store the default cursor appearance of the operating system running on the virtual machine of the cloud desktop server. When the cloud desktop client moves the cursor into the cloud desktop application interface, the cloud desktop application can send a cursor update command to the cloud desktop client to update the cursor appearance displayed on the cloud desktop client to the default cursor appearance corresponding to the cloud desktop server.

Step 503: The cloud desktop server receives the first cursor movement instruction sent by the cloud desktop client.

Step 504: The cloud desktop server sends the first cursor movement instruction to the target application.

Among them, the target application may be a third-party application running on the operating system in the virtual machine of the cloud desktop server, such as a drawing application, a video playback application, etc. The first cursor movement instruction includes the relative position of the cursor in the cloud desktop application interface. The processing of steps 503 and 504 is similar to the processing of steps S3-S5 described above, and will not be described again here.

Step 505: The cloud desktop server obtains the updated first interface of the target application.

After the target application responds to the mouse event corresponding to the first cursor movement instruction, if the interface of the target application needs to be updated, the target application can send an image update request to the rendering engine module of the operating system through the image update module. After receiving the image update request, the rendering engine module of the operating system can send the image update request to the display driver module of the cloud desktop service. The display driver of the cloud desktop service renders the graphics according to the image update request.

It should be noted that, depending on the layers displayed by each image in the target application, the target application can send different image update requests to the operating system, and each image request includes the updated image and its position in the corresponding layer. Since the cursor image corresponds to a separate layer, when the target application needs to update the cursor image, it needs to send an image update request to the operating system separately. The display module included in the cloud desktop service can obtain the updated image of the target application, that is, the first interface of the target application. The first interface may be a complete desktop image, or only include an image updated by the target application.

Step 506: If the cloud desktop server determines that the cursor appearance in the first interface has changed, the changed first cursor appearance is sent to the cloud desktop client, so that the cloud desktop client updates the cursor according to the first cursor appearance.

In the method for updating the cursor provided by this application, after obtaining the first interface, the display module in the cloud desktop service can also determine whether the first interface includes the cursor appearance, and the cursor appearance relative to the cursor appearance applied in the current operating system. Are there changes. Among them, the process of determining whether the cursor appearance changes will not be introduced in detail here.

If it is determined that the cursor appearance has changed, a first cursor appearance update request carrying the first cursor appearance may be sent to the cloud desktop application, so that the cloud desktop client updates the cursor according to the first cursor appearance.

Step 507: The cloud desktop client receives the first cursor appearance update request sent by the cloud desktop server.

Step 508: The cloud desktop client updates the cursor in the target application according to the first operation and the first cursor appearance.

After receiving the first cursor appearance request, the cloud desktop application can update the cursor appearance corresponding to the cursor displayed by the cloud desktop client in the destination application interface to the first cursor appearance through the cursor display module, and can update the cursor appearance according to the first operation. The location of the cloud desktop application interface.

It should be noted that if in step 506, the cloud desktop server determines that the first interface does not include the cursor appearance, or the cursor appearance has not changed. Then the cloud desktop server may not send a cursor appearance update request to the cloud desktop client. For the cloud desktop client, if the cursor appearance update request is not received, the cloud desktop client can always apply the cursor appearance currently being used in the cloud desktop application. After receiving the first cursor appearance request, the cloud desktop client can use the first cursor appearance as the cursor appearance displayed in the cloud desktop application. If the cloud desktop client does not receive other cursor appearance requests again, the cloud desktop client will The client may always use the first cursor appearance as the cursor appearance displayed in the cloud desktop application.

In one possible situation, the above-mentioned step 506 and subsequent processing can be performed when the cloud desktop server receives the cursor hiding request sent by the target application.

Before updating the cursor appearance, the target application needs to send a cursor hiding request to the operating system to cancel the cursor display processing by the operating system. Therefore, it is possible to change the cursor appearance of the operating system only after the operating system in the virtual machine receives the cursor hiding request sent by the target application. Therefore, after receiving the cursor hiding request of the target application, the execution of step 506 and subsequent processes is started.

In addition, when receiving the cursor unhide request sent by the target application, a third cursor appearance update request is sent to the cloud desktop client. The third cursor appearance update request may carry a third cursor appearance, and the third cursor appearance may be The cursor appearance of the system application, such as the default cursor appearance, before the target application updates the first cursor appearance.

If the target application cancels the change to the cursor appearance, it needs to be able to send a cursor unhide request to the operating system so that the operating system resumes display processing of the cursor. Therefore, after the operating system receives the cursor unhide request, it can be determined that the target application has canceled the change to the cursor appearance. Therefore, the cloud desktop service can send a third cursor appearance update to the cloud desktop application after the operating system receives the cursor unhide request. Request to have the Cloud Desktop app change the cursor's cursor appearance back to the previously used cursor appearance. It can be seen that in the embodiment provided by this application, the cloud desktop application can synchronously update the cursor appearance displayed on the cloud desktop server, and can avoid the problem of the cursor not following the hand, which can improve the user's experience of using the cloud desktop application.

Figure 8 is a method for updating the cursor provided by an embodiment of the present application. This method is applied in a cloud desktop system and can synchronize the cursor appearance (cursor image) displayed on the cloud desktop client and the cloud desktop server in the cloud desktop system, and This can avoid the problem of the cursor not following your hand. Referring to Figure 8, the method includes:

Step 801: The cloud desktop client obtains the user's second operation.

The second operation may be triggered by the user moving the mouse of the cloud desktop client. The second operation includes moving the cursor displayed by the cloud desktop client within the cloud desktop application interface. As shown in Figure 7, the user moves the mouse to move the cloud desktop to the cloud desktop application interface. The cursor displayed on the desktop client moves from point C in the cloud desktop application interface to point D in the cloud desktop application interface.

Step 802: The cloud desktop client sends a second cursor movement instruction to the cloud desktop server according to the second operation.

Step 803: The cloud desktop server receives the second cursor movement instruction sent by the cloud desktop client.

Step 804: The cloud desktop server sends the second cursor movement instruction to the target application.

Step 805: The cloud desktop server obtains the updated second interface of the target application.

The processing of steps 802-805 is similar to the processing of steps 502-505, and will not be described again here.

Step 806: If the cloud desktop server determines that the second interface includes the first cursor appearance, it sends a second cursor appearance update request to the cloud desktop client. The second cursor appearance update request instructs the cloud desktop client to use the first cursor appearance.

The first cursor appearance is the cursor appearance displayed by the cloud desktop client in the interface of the target application. For example, before executing step 806, the cloud desktop client has already executed the above step 508 and has updated the cursor appearance of the target application to First cursor appearance.

If the display module in the cloud desktop service determines that the second interface includes the cursor appearance after obtaining the second interface, and the cursor appearance is the first cursor appearance, it means that the target application has not changed the cursor appearance. Therefore, the cloud desktop service can send a second cursor appearance update request carrying the first cursor appearance to the cloud desktop application.

Step 807: The cloud desktop client receives the second cursor appearance update request sent by the cloud desktop server.

Step 808: The cloud desktop client updates the cursor in the target application according to the second operation and the first cursor appearance.

Since the first cursor appearance included in the second cursor appearance update request is the cursor appearance currently used by the cloud desktop application, the first cursor appearance can continue to be used in the cloud desktop application and the cursor can be updated according to the second operation. That is, according to the second operation, the position of the cursor in the cloud desktop application interface of the first cursor appearance is updated. In this way, when the cloud desktop server updates the cursor appearance, the cloud desktop client can be notified through the cursor appearance update request. When the cloud desktop server does not update the cursor appearance, the cloud desktop client can always use the unupdated cursor appearance. The cursor appearance can realize the synchronization of the cursor appearance between the cloud desktop server and the cloud desktop client, which can improve the user experience of using cloud desktop applications.

Figure 9 is a method for updating the cursor provided by an embodiment of the present application. This method is applied in a cloud desktop system and can synchronize the cursor appearance (cursor image) displayed on the cloud desktop client and the cloud desktop server in the cloud desktop system, and This can avoid the problem of the cursor not following your hand. Referring to Figure 9, the method includes:

Step 901: The cloud desktop client obtains the user's third operation. The third operation includes moving the cursor in the interface of the target application.

Step 902: The cloud desktop client sends a second cursor movement instruction to the cloud desktop server according to the third operation.

Since the third operation is the same as the second operation in step 801, the cursor movement instruction triggered by the third operation can also be the second cursor movement instruction.

Step 903: The cloud desktop server receives the second cursor movement instruction sent by the cloud desktop client. The second cursor movement instruction instructs the cursor to be moved in the interface of the target application.

Step 904: The cloud desktop server sends the second cursor movement instruction to the target application.

Step 905: The cloud desktop server obtains the updated second interface of the target application.

The processing of steps 902-905 is similar to the processing of steps 502-505, and will not be described again here.

Step 906: If the cloud desktop server determines that the second interface includes the first cursor appearance, it does not send a cursor appearance update request to the cloud desktop client.

The first cursor appearance is the cursor appearance displayed by the cloud desktop client in the interface of the target application. For example, before executing step 906, the cloud desktop client has already executed the above step 508 and has updated the cursor appearance of the target application to First cursor appearance.

If the display module in the cloud desktop service determines that the second interface includes the cursor appearance after obtaining the second interface, and the cursor appearance is the first cursor appearance, it means that the target application has not changed the cursor appearance. In this case, the cloud desktop service may not send a cursor appearance update request to the cloud desktop application, so that the cloud desktop client continues to use the first cursor appearance.

Step 907: When the cloud desktop client does not receive the third cursor appearance update request sent by the cloud desktop server within the specified time, it updates the cursor in the target application according to the third operation and the first cursor appearance.

Wherein, the designated time may be a period of time after the cloud desktop client sends the second cursor movement instruction to the cloud desktop server, and the specific duration of the designated time may be preset by a technician. Generally, in order to avoid the problem of images not following the cloud desktop application interface, the specified time can be set shorter, for example, it can be shorter than the delay time of data transmission between the cloud desktop client and the cloud desktop service segment. In this way, after the cloud desktop client sends the cursor movement instruction to the cloud desktop server, if it does not receive a cursor appearance update request, it can continue to use the current cursor appearance to display the cursor in the cloud desktop application. If it receives Cursor appearance update request, the current cursor appearance can be updated according to the cursor appearance update request. In this way, when the cloud desktop server updates the cursor appearance, the cloud desktop client can be notified through the cursor appearance update request. When the cloud desktop server does not update the cursor appearance, the cloud desktop client can always use the unupdated cursor appearance. The cursor appearance can realize the synchronization of the cursor appearance between the cloud desktop server and the cloud desktop client, which can improve the user experience of using the cloud desktop.

The method for determining whether the cursor appearance changes is introduced below. See Figure 10. The method includes:

Step 1001: Obtain the first image feature of the target image.

The target image is the updated image carried in the image update request sent by the operating system to the cloud desktop service. The first image feature of the target image includes at least the image size and the pixel value at the specified position. The image size can be the length and width of the target image, and the specified position can be any position in the image, it can be one position or multiple positions, for example, it can be the center point of the image.

As shown in Figure 11, the designated position may include the center point position of the target image, the center point position shifted upward by a first offset along the Y-axis direction, and the center point position is shifted downward by a second offset along the Y-axis direction. The position of the shift amount, the center point position is shifted to the left by the third offset amount along the X-axis direction, and the center point position is shifted to the right by the fourth offset amount along the X-axis direction. The first offset amount and the second offset amount may be called longitudinal offset amounts, and the third offset amount and the fourth offset amount may be called lateral offset amounts. The values of the longitudinal offset and the lateral offset can be preset by technicians and are not limited here.

Step 1002: Determine whether the target image is a cursor image based on the first image feature and the second image feature specifying the appearance of the cursor.

The specified cursor appearance may be a variety of different cursor appearances that may be applied in third-party applications.

After obtaining the first image feature of the target image, comparison can be made based on the pre-stored second image features corresponding to a plurality of different cursor appearances to determine whether the target image is a cursor image.

For example, after the virtual machine on the cloud desktop server is running, the virtual machine can load a matching configuration file. The matching configuration file includes a variety of second image features of different cursor appearances, including image sizes and designated positions corresponding to different cursor appearances. pixel value, etc. After obtaining the first image feature of the target image, the first image feature is compared with each second image feature included in the matching configuration file, and then it is determined whether the target image has a cursor appearance.

Step 1003: If it is determined that the target image is a cursor image, determine whether the target image is the currently used cursor image.

In an implementable manner, after determining that the target image corresponding to the first image feature is the cursor appearance, the target image can be compared again with the image feature corresponding to the cursor appearance currently used by the operating system to determine whether the target image is the cursor appearance. The cursor appearance currently used by the system.

In another implementable manner, after determining that the target image corresponding to the first image feature is the cursor appearance, a cursor identifier corresponding to the cursor appearance that is the same as the first image feature corresponding to the target image is obtained. The obtained cursor identifier can be obtained by determining Whether the cursor identification is consistent with the cursor identification corresponding to the cursor appearance currently used by the operating system determines whether the target image is the cursor appearance currently used by the operating system.

Step 1004: If it is determined that the target image is not the currently used cursor image, determine that the target image is an updated cursor image.

The embodiment of the present application provides a method for determining whether the cursor appearance changes, which can identify whether the image in the image update request is a cursor image when the operating system cannot distinguish whether the image update request sent by the target application corresponds to the cursor image, and can Determines whether the cursor image in the image update request is the changed cursor appearance. Then, after it is determined that the cursor appearance is updated, the updated cursor appearance can be sent to the cloud desktop application, thereby achieving synchronized updates between the cloud desktop client and the cloud desktop server, which can provide users with an experience of using the cloud desktop application.

In a possible case, the above matching configuration file may also include an offset tolerance threshold, which refers to the maximum distance difference between the position of the target image and the position of the mouse. The corresponding method of determining whether the cursor appearance changes may also include: obtaining the first position of the cursor in the desktop image sent by the current cloud desktop application; obtaining the second position of the target image carried in the image update request in the desktop image; determining the second position of the cursor in the desktop image. The distance between the first position and the second position does not exceed the offset tolerance threshold.

If the target image included in the image update request has a cursor appearance, the second position of the target image displayed in the desktop image corresponding to the image update request should be the same as the first position of the cursor in the desktop image sent by the current cloud desktop application. . However, since the cloud desktop service takes a certain amount of time to process the image update request, when the image update request corresponds to the cursor appearance, the second position in the image update request is the same as the first position of the cursor in the desktop image sent by the current cloud desktop application. There may be some distance. However, since the cursor moves continuously in the cloud desktop application and the cloud desktop service takes a short time to process image update requests, this distance is generally relatively small.

Therefore, the technician can set the offset tolerance threshold and determine the distance between the second position in the image update request and the first position of the cursor in the desktop image sent by the current cloud desktop application and the offset tolerance threshold to determine the distance between the second position in the image update request and the first position of the cursor in the desktop image sent by the current cloud desktop application. Whether the target image is the cursor appearance. If the distance is less than or equal to the offset tolerance threshold, it means that the target image in the image update request may have a cursor appearance. If the distance is greater than the offset tolerance threshold, it means that the target image in the image update request does not have a cursor appearance.

In step 1002, the relationship between the distance between the second position in the image update request and the first position of the cursor in the desktop image sent by the current cloud desktop application and the offset tolerance threshold may be determined first. If it is determined that the target image may have a cursor appearance, it may be determined whether the target image is a cursor image based on the first image feature and the second image feature specifying the cursor appearance. If it is determined that the target image does not have a cursor appearance, it can be directly determined whether the target image is a cursor image. This can improve the efficiency of determining whether the target image is an updated cursor appearance, thereby improving the efficiency of synchronizing the updated cursor appearance between the cloud desktop server and the cloud desktop client, and further improving the user experience of using cloud conferencing applications.

In one possible case, after determining that the target image is the updated cursor appearance, the interface display range of the target application corresponding to the image update request can also be obtained, and the interface display range is sent to the cloud desktop application so that the cloud desktop The app uses the updated cursor appearance only within the display range of this interface. When the cloud desktop application determines that the cursor has moved outside the interface display range, it can display the cursor using the cursor appearance before the update. When the cursor moves outside the interface display range, the virtual machine's operating system will update back to the cursor appearance of the previous application. In this way, in the cloud desktop application, it can be judged in advance whether the cloud desktop application has updated the cursor appearance, which can improve the cloud desktop service. The efficiency of cursor appearance synchronization updates between the client and the cloud desktop client can further improve the user experience of using cloud conferencing applications.
