[0034] The idea of ​​the embodiments of the present application is summarized below.

[0035] Currently, these global messages are displayed directly on the VR device without any processing. The content of these global messages is directly displayed in the middle of the device. Figure 1 However, this display method makes it impossible for users to see the message normally in VR devices, and even more impossible to interact with the message. Therefore, a method that can display global messages is needed.

[0036] Based on the problem that users cannot normally see global messages in VR devices in the prior art. An embodiment of the present application provides a method for displaying global messages. After receiving a global message broadcast, the global message to be displayed and the type of global message to be displayed are determined based on the global message broadcast; for any global message to be displayed, an image is drawn for the global message to be displayed to obtain a global message image to be displayed; then, based on the type of global message to be displayed, the display position of the global message to be displayed is determined; and the current display image of the VR device is obtained, and the current display image is used as the background image, and based on the display position of the global message image to be displayed, the global message image to be displayed is superimposed on the current display image to obtain the target image and display it. As a result, the embodiment of the present application realizes the display of global messages in VR devices, so that users can perform operations such as interaction after seeing the global message in the VR device, thereby improving the display effect of global messages in VR devices.

[0037] Before introducing the method for displaying a global message in the embodiment of the present application, the system architecture of the method for displaying a global message in the embodiment of the present application is first described. Figure 2As shown, it is a system architecture diagram in an embodiment of the present application, which includes a global message application 201, a VR application 202 and an image synthesizer 203. The image synthesizer 203 runs in the system as an independent process. In the embodiment of the present application, the image synthesizer 203 as a server communicates with the global message application 201 and the VR application 202 respectively through the inter-process communication IPC, wherein:

[0038] The global message application 201 is used to determine the global message to be displayed and the type of the global message to be displayed based on the global message broadcast after receiving the global message broadcast; and for any global message to be displayed, draw an image of the global message to be displayed through the global message application to obtain an image of the global message to be displayed;

[0039] A receiving VR application 202 is used to send a currently displayed image to an image synthesizer 203;

[0040] The image synthesizer 203 determines the display position of the global message to be displayed based on the type of the global message to be displayed; and uses the currently displayed image as a background image, and based on the display position of the global message image to be displayed, superimposes the global message image to be displayed on the currently displayed image to obtain a target image.

[0041] In the embodiment of the present application, the image synthesizer is run as an independent process in the system. The image synthesizer communicates with the VR application and the global message application respectively through inter-process communication, and can receive image data from different applications and synthesize the final image output. The global message application that draws the global message is used as a client of the image synthesizer. The global message application is superimposed on the VR application through the processing of the image synthesizer to provide a more seamless user experience. Specifically, Figure 3 As shown, from Figure 3 As can be seen, the global messages of the global application are displayed on the upper layer of the VR application.

[0042] The method for displaying a global message in an embodiment of the present application is described below with reference to the accompanying drawings. Figure 4 FIG. 1 is a flow chart of a method for displaying a global message, which may include the following steps:

[0043] Step 401: after receiving a global message broadcast, determining a global message to be displayed and a type of the global message to be displayed based on the global message broadcast;

[0044] In the embodiment of the present application, it is ensured that a system service runs automatically when the VR device is started or the user manually starts the system service when necessary; the task of the system service is to monitor the global message broadcast sent in the VR system. The system service can monitor actions of specific intents by registering broadcast receivers, and these actions represent various types of global messages. For example, toast, notification, dialog, etc. That is, the global message broadcast in the embodiment of the present application includes the global message to be displayed and the type of global message to be displayed.

[0045] In one embodiment, after the execution step, the global message needs to be added to the message queue, such as Figure 5 FIG. 1 is a flow chart of determining the execution order of global messages to be displayed. Specifically, the following steps may be included:

[0046] Step 501: Determine the priority of the global message to be displayed based on the type of the global message to be displayed;

[0047] The types of global messages in the embodiment of the present application include toast type, notification type and dialog type. The priority of each type of global message to be displayed is pre-set, and the embodiment of the present application does not limit the priority of each type of global message to be displayed.

[0048] Step 502: determining a target position of the global message to be displayed in a message queue according to the priority of the global message to be displayed, and adding the global message to be displayed to the target position in the message queue;

[0049] In the embodiment of the present application, if there is a global message of the same type as the global message to be displayed in the message queue, the position behind the position of the global message of the same type as the global message to be displayed and the position in front of the position of the global message of a different type from the global message to be displayed are determined as the target position of the global message to be displayed.

[0050] For example, if the message queue includes: global message a, global message b, global message c, global message d, global message e. If the target position of global message m needs to be determined, if the types of global message a, global message b and global message m are the same, then the middle of global message b and global message c is determined as the target position of global message m. That is, global message m is added to the message queue, and the message queue is: global message a, global message b, global message m, global message c, global message d, global message e.

[0051] In the embodiment of the present application, if there is no global message of the same type as the global message to be displayed in the message queue, the target position of the global message to be displayed in the message queue is determined according to the priority of the global message to be displayed.

[0052] For example, if the message queue includes: global message a, global message c, global message d, global message e. If the target location of global message m needs to be determined, and the message queue does not include global messages of the same type as global message m, then global message m is added to the message queue, and the message queue is: global message a, global message m, global message c, global message d, global message e.

[0053] Step 503: Obtain the global messages to be displayed in sequence according to the sequence of the global messages to be displayed in the message queue.

[0054] The higher the priority of the global message to be displayed in the message queue in the embodiment of the present application, the higher the priority is. For example, the message queue is: global message a, global message m, global message c, global message d, global message e. Then the order of obtaining each global message to be displayed is: global message a→global message m→global message c→global message d→global message e.

[0055] Step 402: for any global message to be displayed, draw an image of the global message to be displayed to obtain an image of the global message to be displayed;

[0056] In the embodiment of the present application, the global message to be displayed can be drawn by using openGL or MGUI. Since the image drawing method belongs to the method in the prior art, the embodiment of the present application will not be repeated. And the specific image drawing method can be set according to the actual situation. The embodiment of the present application does not limit the image drawing method here.

[0057] Step 403: Determine a display position of the global message to be displayed based on the type of the global message to be displayed;

[0058] In one embodiment, the display position of the global message to be displayed is determined by the following two methods:

[0059] Mode 1: If the type of the global message is a type that does not require interaction, the designated position is determined as the display position of the global message to be displayed.

[0060] The designated location in the embodiment of the present application can be set according to the specific actual situation, and the embodiment of the present application does not limit the designated location. For global messages that do not require user interaction (such as toast), in the embodiment of the present application, they are displayed in an optimized manner in the appropriate position of the VR environment to ensure that the user can see it without interfering with the current activity.

[0061] Method 2: If the type of the global message is a type that requires interaction, the display position of the global message to be displayed is obtained based on the current actual head tracking data and predicted head tracking data of the VR device, wherein the predicted head tracking data is obtained based on historical head tracking data that is before the current actual head tracking data.

[0062] The predicted head tracking data in the embodiment of the present application is obtained by inputting the historical head tracking data into the prediction model, wherein the prediction model may be ARIMA (Autoregressive Integrated Moving Average Model) or other time series models. The prediction model is not limited in the embodiment of the present application, and the prediction model in the embodiment of the present application may be set according to the specific actual situation.

[0063] In one embodiment, the display position of the global message to be displayed is determined in the following manner:

[0064] Utilizing the pre-set correspondence between the target head tracking data and the display position, the target display position corresponding to the current target head tracking data is determined, and the target display position is determined as the display position of the global message to be displayed, wherein the current target head tracking data includes the current actual head tracking data and the predicted head tracking data.

[0065] For example, Figure 6 As shown, it is a schematic diagram of the correspondence between the target head tracking data and the display position. If the current actual head tracking data is data 1, and the predicted head tracking data is data 2, then based on the correspondence in the figure, it can be determined that the target display position is position A.

[0066] For global messages that users need to interact with, an interactive interface is created in the embodiment of the present application. When the user interacts with the interactive interface, these interactive events are captured; corresponding operations are performed based on the interactive events, and the operation results are fed back to the user.

[0067] The feedback in the embodiment of the present application can be visual, such as updating the interactive interface, or through other sensory means, such as sound or vibration. The interaction method in the embodiment of the present application is the same as the interaction method in the VR device, and the embodiment of the present application will not be repeated here.

[0068] Step 404: Acquire the current display image of the VR device, and use the current display image as the background image, and based on the display position of the global message image to be displayed, superimpose the global message image to be displayed on the current display image to obtain the target image and display it.

[0069] The currently displayed image in the embodiment of the present application includes the currently displayed image for the left eye and the currently displayed image for the right eye, and the target image includes the target image for the left eye and the target image for the right eye. And the display position in the embodiment of the present application includes the display position for the left eye and the display position for the right eye.

[0070] In one embodiment, step 404 can be specifically implemented as follows: obtaining the left eye currently displayed image and the right eye currently displayed image of the VR device, taking the left eye currently displayed image as the background image, and based on the left eye display position of the global message image to be displayed, superimposing the global message image to be displayed on the left eye currently displayed image to obtain a left eye target image; and taking the right eye currently displayed image as the background image, and based on the right eye display position of the global message image to be displayed, superimposing the global message image to be displayed on the right eye currently displayed image to obtain a right eye target image.

[0071] like Figure 7 As shown, in the embodiment of the present application, the global message image is used as the foreground image, and the current display image is used as the background image, and the two images are synthesized to obtain the target image.

[0072] In the embodiment of the present application, the target image may be time-warped or asynchronously time-warped to adjust the target image, and the adjusted target image may be displayed so that the displayed target image matches the actual viewing angle of the user.

[0073] In order to avoid repeated display of global messages, in one embodiment, after executing step 404, the global message to be displayed corresponding to the target image is deleted from the message queue.

[0074] For example, the message queue is: global message a, global message m, global message c, global message d, global message e. If global message a has been displayed, the message queue becomes: global message m, global message c, global message d, global message e.

[0075] In order to further understand the method in this application, Figure 8FIG. 1 is a flow chart of a method for displaying a global message in the present application, which may include the following steps:

[0076] Step 801: after receiving a global message broadcast, determining a global message to be displayed and a type of the global message to be displayed based on the global message broadcast;

[0077] Step 802: Determine the priority of the global message to be displayed based on the type of the global message to be displayed;

[0078] Step 803: determining a target position of the global message to be displayed in the message queue according to the priority of the global message to be displayed;

[0079] Step 804: adding the global message to be displayed to the target position in the message queue;

[0080] Step 805: sequentially acquiring the global messages to be displayed in the message queue according to the order of the global messages to be displayed;

[0081] Step 806: for any global message to be displayed, draw an image of the global message to be displayed to obtain an image of the global message to be displayed;

[0082] Step 807: Determine whether any of the global messages to be displayed is of a type that requires interaction, if so, execute step 808, if not, execute step 809;

[0083] Step 808: determining the designated position as the display position of the global message to be displayed;

[0084] Step 809: obtaining a display position of the global message to be displayed based on the current actual head tracking data and the predicted head tracking data of the VR device, wherein the predicted head tracking data is obtained based on the historical head tracking data that is before the current actual head tracking data;

[0085] Step 810: Obtain the left eye current display image and the right eye current display image of the VR device;

[0086] Step 811: using the left eye current display image as a background image, and based on the left eye display position of the global message image to be displayed, superimposing the global message image to be displayed on the left eye current display image to obtain the left eye target image;

[0087] Step 812: using the right eye current display image as a background image, and based on the right eye display position of the global message image to be displayed, superimposing the global message image to be displayed on the right eye current display image to obtain the right eye target image;

[0088] The execution sequence of step 811 and step 812 in the embodiment of the present application is not limited in the embodiment of the present application. Step 811 may be executed first, and then step 812. Step 812 may also be executed first, and then step 811. Step 811 and step 812 may also be executed simultaneously.

[0089] Step 813: Delete the global message to be displayed corresponding to the target image from the message queue.
