The virtual reality equipment can provide services for users to watch virtual reality applications or obtain virtual reality experiences through non-virtual reality applications, and can be virtual reality helmets, virtual reality glasses and the like.
The application switching method, as shown in fig. 2, includes:
in step S2100, when a trigger signal for switching from the currently displayed first application to the second application is acquired, a full-screen display layer is created.
The full-screen display layer is arranged at the forefront of the application display area so as to cover the application display area.
In this embodiment, the first application and the second application are applications that support being watched by a virtual reality device to obtain a virtual reality experience, and the applications may be virtual reality applications or non-virtual reality applications (for example, native applications developed based on an Android system). It should be understood that the terms "first," "second," and the like are used merely for convenience in distinguishing between similar elements and not necessarily for describing a sequential or chronological order.
The trigger signal for switching from the currently displayed first application to the second application may be generated automatically by the virtual reality device of the embodiment having the application, or generated by triggering according to an operation performed by a user on the virtual reality device or an external device (e.g., a mobile phone) of the virtual reality device, which is not limited in this embodiment.

In this embodiment, the full-screen display layer created when the trigger signal for switching the application is acquired is independent of any application, can be independently operated, and has no logical association with the operation of the currently displayed first application and the second application to be switched.
The full-screen display layer is arranged at the top of the display area and covers the application display area, so that the content displayed in the full-screen display layer is visually observed by a user. In the subsequent steps in this embodiment, the full-screen display layer can be controlled to display the preset image in the application switching process in the virtual reality display mode, so that the phenomena of black screen and picture pause caused by long switching processing time between virtual reality applications or between the virtual reality applications and non-virtual reality applications are avoided, the user can obtain the virtual reality visual experience when the applications are switched, and the visual display optimization is realized. Meanwhile, the full-screen display layer is not logically associated with the running application, the running performance of the equipment is not influenced, and the realization efficiency is high.
Specifically, a full-screen display layer in this embodiment may be created by using a function of creating a layer (display layer) provided by a similar Android system, the priority of the full-screen display layer is set to be the highest, the attribute is a full screen, the full-screen display layer is controlled to be displayed in a virtual reality mode, the display content is a preset image and the time for displaying the preset image, the independent display layer may be operated at the start of application switching, and the independent display layer is deleted after the switching is successful, so that the operation performance of the application is not affected, and the visual display optimization is realized.
Step S2200, displaying a preset image in a virtual reality display mode on a full screen display layer when the switching from the first application to the second application is executed,
specifically, the switching of the first application to the second application includes exiting the display of the first application and launching the display of the second application. The display of exiting the first application may be the display of ending the exit of the first application or may be the display of exiting only the first application, which is still running in the background. The display of starting the second application may be a display of starting the second application running in the background, or may be a display of starting a second application not running.
And in the whole process of executing the switching from the first application to the second application, displaying a preset image in a virtual reality display mode through the independent display layer. The virtual reality display mode is a display mode for integrating images, audios and videos through operation processing to realize interactive three-dimensional dynamic views and entity behaviors, and virtual reality experience immersed in a simulation environment is provided.
The preset image is displayed in the virtual reality display mode, the phenomena of black screen and picture blocking caused by long switching processing time between virtual reality applications or between the virtual reality applications and non-virtual reality applications are avoided, a user can obtain the virtual reality visual experience of the flow when the applications are switched, and visual display optimization is achieved. Meanwhile, the full-screen display layer is not in logical association with the running application, the running performance of the application is not influenced, and the implementation efficiency is high.
Specifically, the application switching method provided in this embodiment further includes:
and generating the preset image supporting the virtual reality display mode according to the acquired image materials through the full-screen display layer.
The generating of the preset image may include:
constructing a virtual reality environment in a full screen display layer, fusing the pixel materials with a preset virtual reality scene based on the virtual reality environment to generate a preset image,
the virtual reality environment is used for implementing steps of left-right eye rendering, deformation, optical processing, and the like, and specifically, the purpose of constructing the virtual reality environment may be accomplished through a program code or an instruction set, which is not limited in this embodiment.
Based on the virtual reality environment, the image material can be fused with a preset virtual reality scene, the virtual reality scene can be a 3D scene model preset according to specific application requirements, for example, the virtual reality scene is limited by the operational capability of the device implementing the embodiment, and can be set as a simple scene model with less processing resource consumption, or an interface can be provided for a user to select or upload a scene model meeting visual requirements.
The preset image obtained after the image material and the virtual reality scene are fused is displayed in the virtual reality display mode through the full-screen display layer, the virtual reality visual demand of a user during application switching can be met, meanwhile, the application running performance is not influenced, and the user experience is improved.
The image material is a material that can be used to generate a preset image that supports virtual reality display mode display, and may be a static or dynamic image.
In one example, the image material includes a first image material obtained from the first application, and the application switching method further includes:
when the first application is a non-virtual reality application, acquiring an image of an end frame of the first application as a first image material, or when the first application is a virtual reality application, acquiring an image generated by monocular data provided by the first application as the first image material;
when the display of the first application is exited, the step of generating and displaying the preset image in the present embodiment is performed according to the first image material.
The method comprises the steps of obtaining a first image material according to the application type of a first application, extracting an image of an end frame of the first application as the image material when the first application is a non-virtual reality application, wherein the non-virtual reality application generally provides single-eye data of a left eye and a right eye respectively for left-eye and right-eye rendering processing to present an application image providing virtual reality experience when the first application is the non-virtual reality application, and the single-eye data provided by the first application and used for presenting the end or quitting the application can be extracted as the first image material.
When quitting from the display of first application, through full-screen display layer to the preset image that the virtual reality mode display generated according to first image material for the user can not only obtain smooth virtual reality's visual experience when the application switches, can also watch the application that confirms current display and quit, tracks application switching progress, reduces psychological wait expectation, promotes user experience.
In another example, the image material includes a second image material obtained from a second application, and the application switching method further includes:
when the second application is a non-virtual reality application, acquiring an image of a start frame of the second application as a second image material, or when the second application is a virtual reality application, acquiring an image generated by monocular data provided by the second application as a second image material;
and when the display of the second application is started, executing the step of generating and displaying the preset image according to the second image material.
The method includes the steps that a second image material is obtained according to the application type of a second application, when the second application is a non-virtual reality application, an image of a starting frame of the second application is extracted to serve as the image material, when the second application is the non-virtual reality application, the non-virtual reality application generally provides single-eye data of a left eye and a right eye respectively to conduct left-eye and right-eye rendering processing to present application images providing virtual reality, and the single-eye data provided by the second application and used for presenting starting or entering the application can be extracted to serve as the second image material.
When the display of the second application is started to enter, the preset image generated according to the second image material is displayed in the virtual reality mode through the full-screen display layer, so that a user can not only obtain smooth visual experience of virtual reality when the application is switched, but also can watch and confirm the application to be switched when the application is started to enter, the application switching progress is tracked, the psychological waiting expectation is reduced, and the user experience is improved.
In practical application, because the calculation amount of the virtual reality application is large, the processing time delay is long from the time of triggering the display of the started application to the time of starting the display of the application, and a black screen or a picture pause phenomenon may occur in the process.
In this embodiment, the image material includes a preset third image material, and the step of generating and displaying the preset image is performed according to the third image material after the display of exiting the first application is completed and before the display of entering the second application is started.
The preset third image material may be an animation material preset according to a specific application requirement, and includes static or dynamic images, videos, and the like, for example, the preset third image material is limited by the computing capability of the device implementing the embodiment, and may be set as a static image with less processing resource consumption, or may provide an interface for a user to select or upload an image meeting a visual requirement.
After the display of exiting the first application is finished and before the display of entering the second application is started, the preset image generated according to the third image material is displayed in the virtual reality mode through the full-screen display layer, and the situation that the current display application exits from the picture or the black screen when the application is started and enters the application to be switched is avoided, so that a user can obtain smooth virtual reality visual experience, and the application running performance is not influenced.
In practical applications, the processing capability of the device according to this embodiment is limited, and more processing resources may be consumed to generate the corresponding preset image by obtaining the image material from the application when the application is switched, so that processing delay is caused, and a phenomenon of short-time black screen or image blocking still cannot be avoided.
Therefore, in the present embodiment, the image material may be a preset default animation material. The default animation material comprises static or dynamic images, videos and the like, can be an animation material with small storage capacity and simple content, so that processing resources consumed in subsequent steps are reduced, the processing efficiency is further improved, the phenomenon of short black screen or picture blockage caused by processing delay is avoided, and the visual experience of the virtual reality of a user is guaranteed.
Step S2300, after the display start of the second application is completed, deleting the full-screen display layer, and displaying the content of the second application in the application display area.
In the process of executing application switching, displaying a preset image in a virtual reality display mode through a full-screen display layer, executing application switching in parallel in a background, wherein the application switching comprises quitting a first application and starting a second application, deleting the full-screen display layer after the second application is started, namely the application switching is successful, and switching to display the second application through an application display area. The phenomenon of picture blocking or screen blacking in the application switching process is avoided, so that a user can obtain smooth virtual reality visual experience in the application switching process, the running performance of background application is not influenced, and the implementation is simple and efficient.
