Description

Background Art

[0002] Generally speaking, the faster the VR application starts, the better the user experience. Currently, mainstream VR (Virtual Reality) applications are developed using Unity. If the model in the application is complex, the VR application startup is slower than pure 2D (Two Dimensional) applications. As a 6Dof (six degrees of freedom) VR application, not only model loading but also slam (Simultaneous Localization and Mapping) startup must be considered, because after the application is started, the 6Dof pose needs to be used normally, which requires slam to be started normally.

[0003] At present, 6dof VR devices usually use the SLAM function based on the CV (Computer Vision) solution. The SLAM function based on the CV solution usually requires a lot of calculations and data processing, and each VR application startup and exit, as well as switching to the next VR application, requires the process of starting the SLAM function and the process of closing the SLAM function. This process takes some time, so it will cause users to start applications from the desktop slowly when using 6dof VR devices, resulting in a poor user experience. Summary of the invention

[0004] The present application provides a method for starting a VR application and a VR device, which are used to increase the startup speed of the VR application and improve the user experience.

[0005] In a first aspect, an embodiment of the present application provides a method for starting an application, the method comprising:

[0006] When the VR device is powered on and receives a screen-on instruction, a screen status value of the VR device is obtained, wherein the screen status value is used to indicate whether the screen of the VR device has been turned on;

[0007] If it is determined that the screen status value is the first status value, the real-time positioning and map building slam function is turned on, and the VR mode status value is set to the first mode value, wherein the first status value is used to indicate that the screen of the VR device has been lit, the VR mode status value is used to indicate whether the VR device has turned on the slam function, and the first mode value is used to indicate that the VR device has turned on the slam function;

[0008] If a command to start a target application is received from a user, a real-time screen action command of the user on the target application is obtained, and based on the real-time screen action command, the target application content corresponding to the real-time screen action command is rendered and displayed, until a target application exit command sent by the user is received, the target application is exited;

[0009] When a screen-off instruction is received and the acquired screen status value is the second status value, the slam function of the VR device is turned off, and the VR mode status value is set to the second mode value, wherein the second mode value is used to indicate that the slam function of the VR device has been turned off.

[0010] A second aspect of the present application provides a VR device, including a processor and a memory, wherein the processor and the memory are connected via a bus;

[0011] The memory stores a computer program, and the processor is configured to perform the following operations based on the computer program:

[0012] When the VR device is powered on and receives a screen-on instruction, a screen status value of the VR device is obtained, wherein the screen status value is used to indicate whether the screen of the VR device has been turned on;

[0013] If it is determined that the screen status value is the first status value, the real-time positioning and map building slam function is turned on, and the VR mode status value is set to the first mode value, wherein the first status value is used to indicate that the screen of the VR device has been lit, the VR mode status value is used to indicate whether the VR device has turned on the slam function, and the first mode value is used to indicate that the VR device has turned on the slam function;

[0014] If a command to start a target application is received from a user, a real-time screen action command of the user on the target application is obtained, and based on the real-time screen action command, the target application content corresponding to the real-time screen action command is rendered and displayed, until a target application exit command sent by the user is received, the target application is exited;

[0015] When a screen-off instruction is received and the acquired screen status value is the second status value, the slam function of the VR device is turned off, and the VR mode status value is set to the second mode value, wherein the second mode value is used to indicate that the slam function of the VR device has been turned off.

[0016] According to a third aspect provided by an embodiment of the present invention, a computer storage medium is provided, wherein the computer storage medium stores a computer program, and the computer program is used to execute the method as described in the first aspect.

[0017] In the above embodiment of the present application, the slam function is turned on after the screen is first lit after the VR device is started, and the slam function is not turned off until the screen of the VR device is turned off. During this period, the slam function is always turned on, so no matter whether it is starting or exiting an application or switching an application, it is not necessary to execute the process of turning on the slam function and the process of turning off the slam function every time, so the startup time of the application in the 6dof VR device is reduced and the startup speed of the VR application is improved.

[0025] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0026] Based on the exemplary embodiments described in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the claims attached to this application. In addition, although the disclosure in this application is introduced according to one or several exemplary examples, it should be understood that each aspect of the disclosure can also constitute a complete implementation method separately.

[0027] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0028] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a series of components is not necessarily limited to those components clearly listed, but may include other components not clearly listed or inherent to these products or devices.

[0029] The term "module" as used in this application refers to any known or later developed hardware, software, firmware, artificial intelligence, fuzzy logic or combination of hardware and / or software code that is capable of performing the functions associated with that element.

[0030] The idea of ​​the embodiments of the present application is summarized below.

[0031] At present, the startup and exit of each VR application in the 6dof VR device requires the process of starting and closing the slam function when switching to the next application. This process usually takes some time, which results in a slow speed for users to start applications from the desktop when using the 6dof VR device, and a poor user experience. For example, when the user starts VR application 1, the slam function needs to be started. When VR application 1 is closed or running in the background, the slam function is turned off. When the user starts VR application 2, the slam function is started. When VR application 2 is closed or running in the background, the slam function is turned off. Therefore, each time an application is opened, the slam function needs to be restarted, and when the application is exited, the slam function needs to be turned off, resulting in a long time for application startup and a slow application startup speed.

[0032] like Figure 1 As shown, it is a schematic diagram of a scene for starting a VR application in the prior art. Figure 1 It can be seen that when a VR application in the prior art is started, the sxrInitialize method in the SDK (Software Development Kit) corresponding to the VR application is first called for initialization, and then the SDK calls the QVRServiceClient_Create method in the QVR (Qualcomm Virtual Reality) service to connect to the QVR service. Then after the VR application is started (application onResume or focus), the VR application calls the sxrBeginXr method in the SDK, and the QVRServiceClient_StartVRMode method of the QVR service is called in the sxrBeginXr in the SDK to notify the QVR service to turn on the SLAM function. Since it takes time to start the SLAM function, the sxrBeginXr method will block and wait during the startup until the SLAM function is started. When the VR application exits (that is, when the application onPause loses focus), the VR application calls the sxrEndXr method so that the sxrEndXr method in the SDK calls the QVRServiceClient_StopVRMode method in the QVR service to notify the QVR service to turn off the SLAM function. However, it also takes time to turn off the slam function. During the shutdown period, the sxrEnd method will block and wait until the slam function is turned off. Therefore, in the prior art, each time an application is started or switched, it needs to be executed once. Figure 1 The process in will cause the VR application to start slowly.

[0033] Based on the problem of slow startup speed of VR applications in the prior art, the embodiment of the present application provides a method for starting a VR application, which turns on the slam function after the screen is turned on for the first time after the VR device is started, and turns off the slam function until the screen of the VR device is turned off. During this period, the slam function is always turned on, so whether it is starting or exiting an application or switching applications, it is not necessary to execute the process of turning on the slam function and the process of turning off the slam function every time, so the startup time of the application in the 6dof VR device is reduced and the startup speed of the VR application is improved.

[0034] Below, the method for starting the VR application in this application is introduced in detail with reference to the accompanying drawings.

[0035] like Figure 2 FIG. 1 is a flow chart of a method for starting a VR application, which may include the following steps:

[0036] Step 201: When the VR device is powered on and receives a screen-on instruction, a screen status value of the VR device is obtained, wherein the screen status value is used to indicate whether the screen of the VR device has been turned on;

[0037] To ensure that the VR application can be started smoothly, after the VR device is powered on and before receiving the screen-on command, in one embodiment, a connection is established between the display synthesis system SurfaceFlinger service and the virtual reality mode control VrmodeControl service, and the VrmodeControl service is connected to the Qualcomm virtual reality qvr service.

[0038] In one embodiment, the screen status value of the VR device is obtained in the following manner: the screen status value is obtained through the SurfaceFlinger service of the display synthesis system.

[0039] Among them, in the embodiment of the present application, the screen status value is obtained by the setPowerModelntrenal method in the SurfaceFlinger service. However, in the embodiment of the present application, the method for obtaining the screen status value is not limited, and it can be set according to the actual situation.

[0040] Step 202: If it is determined that the screen status value is the first status value, the real-time positioning and map building slam function is enabled, and the VR mode status value is set to the first mode value, wherein the first status value is used to indicate that the screen of the VR device has been lit, the VR mode status value is used to indicate whether the VR device has enabled the slam function, and the first mode value is used to indicate that the VR device has enabled the slam function;

[0041] In one embodiment, the real-time positioning and map building slam function is enabled in the following manner, and the VR mode state value is set to the first mode value:

[0042] The SurfaceFlinger service sends a positioning start instruction to the virtual reality mode control VrmodeControl service, so that the VrmodeControl service instructs the Qualcomm virtual reality QVR service to turn on the slam function based on the positioning start instruction and sets the VR mode state value to the first mode value.

[0043] Step 203: if a command to start the target application is received from the user, the real-time screen action command of the user for the target application is obtained, and the target application content corresponding to the real-time screen action command is rendered and displayed based on the real-time screen action command, until a target application exit command sent by the user is received, then the target application is exited;

[0044] Among them, obtaining real-time screen action instructions in the implementation of this application is obtained by obtaining pose.

[0045] In order to ensure that the VR application can be started smoothly, in one embodiment, after receiving the instruction sent by the user to start the target application, the SDK of the target application is connected to the QVR service. And before obtaining the real-time screen action instruction of the user for the target application, the VR mode state value is determined to be the first mode value.

[0046] In one embodiment, the VR mode state value is obtained in the following manner:

[0047] The VR mode status value is obtained from Qualcomm Virtual Reality QVR service through the software development kit SDK of the target application.

[0048] In order to save computing resources, in one embodiment, after receiving the target application exit instruction sent by the user, the SDK of the target application is disconnected from the QVR service.

[0049] In one embodiment, the target application exit instruction includes ending the process of the target application or switching the process of the target application to background operation.

[0050] Step 204: When a screen-off instruction is received and the acquired screen status value is the second status value, the slam function of the VR device is turned off, and the VR mode status value is set to the second mode value, wherein the second mode value is used to indicate that the slam function of the VR device has been turned off.

[0051] In one embodiment, the positioning function of the VR device is turned off and the VR mode state value is set to the second mode value in the following manner:

[0052] A positioning shutdown instruction is sent to the VrmodeControl service through the SurfaceFlinger service, so that the VrmodeControl service instructs the qvr service to shut down the slam function based on the positioning shutdown instruction and sets the VR mode state value to the second mode value.

[0053] The following is a detailed description of the control process in the VR application startup method in the embodiment of the present application. Figure 3 As shown, the control process for starting a VR application in a VR device may include the following steps:

[0054] Step 301: When the VR device is powered on, the SurfaceFlinger service in the VR device establishes a connection with the VrmodeControl service in the VR device;

[0055] The SurfaceFlinger service in the embodiment of the present application establishes a connection with the VrmodeControl service by calling the HxrControllerClient_Create method.

[0056] Step 302: The VrmodeControl service in the VR device establishes a connection with the qvr service in the VR device in the VR device;

[0057] The VrmodeControl service in the embodiment of the present application establishes a connection with the qvr service by calling the QVRServiceClient_Create method.

[0058] It should be noted that the method of establishing a connection between the SurfaceFlinger service and the VrmodeControl service and the method of establishing a connection between the VrmodeControl service and the qvr service described above in the embodiment of the present application are only used for illustration and do not limit the method of establishing a connection. The specific method of establishing a connection can be set according to actual conditions.

[0059] Step 303: After receiving the screen-on instruction, the SurfaceFlinger service obtains the screen status value and determines that the screen status value is a first status value;

[0060] Step 304: The SurfaceFlinger service sends a positioning start instruction to the virtual reality mode control VrmodeControl service;

[0061] In the embodiment of the present application, the SurfaceFlinger service sends a positioning start instruction to the VrmodeControl service by calling the HxrControllerClient_Start method. The specific method of sending the instruction can be set according to the actual situation, and the embodiment of the present application is not limited here.

[0062] Step 305: The VrmodeControl service instructs the Qualcomm virtual reality qvr service to enable the slam function based on the positioning enable instruction;

[0063] The VrmodeControl service in the embodiment of the present application sends an instruction to the qvr service to enable the slam function by calling the QVRServiceClient_StartVRMode method. However, the specific method can be set according to the actual situation, and the embodiment of the present application is not limited here.

[0064] Step 306: After receiving the positioning start instruction, the qvr service starts the slam function and sets the VR mode state value to the first mode value;

[0065] Step 307: After receiving the screen off instruction, the SurfaceFlinger service obtains the screen status value;

[0066] Step 308: The SurfaceFlinger service determines that the screen status value is the second mode value, and sends a positioning close instruction to the VrmodeControl service;

[0067] In the implementation of this application, the first mode value is 2, and the second mode value is 0, but the first mode value and the second mode value can be set according to specific actual conditions. The embodiment of this application does not limit the first mode value and the second mode value.

[0068] Step 309: The VrmodeControl service instructs the qvr service to turn off the slam function based on the positioning shutdown instruction;

[0069] Step 310: After receiving the positioning shutdown instruction, the qvr service turns off the slam function and sets the VR mode state value to the second mode value.

[0070] In order to further connect the method in this application, the method for starting the VR application in this application is introduced in combination with the usage scenario. Figure 4 As shown, it is a schematic diagram of the process of starting the use scenario of the VR application in this application, which may include the following steps:

[0071] Step 401: When the target application in the VR device is started, the target application is initialized;

[0072] The method of initialization in the embodiment of the present application is to call the sxrlnitialize method in the SDK of the target application to initialize. However, the embodiment of the present application does not limit the method of initialization, and it can be set according to the specific actual situation.

[0073] Step 402: the SDK calls the QVRServiceClient_Create method in the QVR service to connect to the QVR service;

[0074] Step 403: After the target application is started, the sxrBeginXr method of the SDK of the target VR application is called;

[0075] Step 404: SDK calls the QVRServiceClient_GetVRMode method of the qvr service through the sxrBeginXr method to obtain the VR mode status value;

[0076] Step 405: The qvr service sends the VR mode status value to the sdk;

[0077] Step 406: The SDK determines that the VR mode state value is the first mode value;

[0078] Step 407: the target application obtains the real-time screen action instruction of the user to the target application, and renders and displays the target application content corresponding to the real-time screen action instruction based on the real-time screen action instruction;

[0079] Step 408: When the target VR application exits, the sxrEndXr method of the SDK is called;

[0080] Step 409: SDK calls the QVRServiceClient_GetVRMode method of the qvr service through the sxrEndXr method to obtain the VR mode status value;

[0081] Step 410: the qvr service sends the VR mode status value to the sdk;

[0082] Step 411: The SDK determines that the VR mode state value is the first mode value;

[0083] Step 412: The target application calls the sxrShutdown method of the SDK;

[0084] Step 413: The SDK calls the QVRServiceClient_Destroy method of the QVR service to disconnect from the QVR service.

[0085] Based on the same inventive concept, the VR application startup method disclosed above can also be implemented by a VR application startup device. The effect of the VR application startup device is similar to that of the aforementioned method, and will not be repeated here.
