背景技术
虚拟现实(Virtual Reality，VR)眼镜是指一种通过利用眼镜显示器将人的对外界的视觉、听觉封闭，引导用户完全沉浸在该虚拟环境中，其中，虚拟环境中的显示内容会随着人的观看角度变化而发生改变。随着电子技术的不断发展，虚拟现实眼镜已经允许用户通过其它外设器件(例如手柄)根据自己在虚拟环境中的视点和位置来操作虚拟画面中的控件。
目前，手机可以通过数据线与虚拟现实眼镜建立连接，如图1a所示，手机中显示的界面可以实时的“投屏”到虚拟现实眼镜的显示器上。用户可以通过操作与虚拟显示眼镜相连的手柄，完成操作眼镜显示器中虚拟画面中的控件，也就是说用户在虚拟现实眼镜中完成对手机的操作。
目前手机可以实现画中画显示，也就是说，手机可以支持两个应用程序的显示界面同时处于活动状态，例如，如图1b所示，手机显示屏的小窗口悬浮显示视频聊天应用的画面，显示屏的大窗口显示微信朋友圈的画面，当用户在查看朋友圈的同时，视频聊天应用的画面会正常播放。但是这种多窗口显示虽然能够同时显示两个应用的活动内容，但是小窗口有可能会遮挡大窗口的部分内容。而目前虚拟显示眼镜也只是完全实时地投影手机显示的界面，所以在虚拟现实眼镜的显示器中也是存在部分画面被遮挡的问题，影响用户的使用体验。

下面介绍传感器模块180的功能。
陀螺仪传感器180A，可以用于确定电子设备100的运动姿态。在一些实施例中，可以通过陀螺仪传感器180A确定电子设备100围绕三个轴(即，x，y和z轴)的角速度。即陀螺仪传感器180A可以用于检测电子设备100当前的运动状态，比如抖动还是静止。

无线通信模块152可以提供应用在电子设备100上的包括无线局域网(wireless local area networks，WLAN)(如无线保真(wireless fidelity，Wi-Fi)网络)，蓝牙(bluetooth，BT)，全球导航卫星***(global navigation satellite system，GNSS)，调频(frequency modulation，FM)，近距离无线通信技术(near field communication，NFC)，红外技术(infrared，IR)等无线通信的解决方案。无线通信模块152可以是集成至少一个通信处理模块的一个或多个器件。无线通信模块152经由天线2接收电磁波，将电磁波信号调频以及滤波处理，将处理后的信号发送到处理器110。无线通信模块152还可以从处理器110接收待发送的信号，对其进行调频，放大，经天线2转为电磁波辐射出去。本申请实施例中，电子设备100可以利用蓝牙连接手柄。

虚拟屏幕内容获取模块，用于在用户点击启动的应用时，获取应用中的内容，并将应用中的内容通过畸变渲染，以实现在虚拟环境中显示。
应用程序框架层为应用程序层的应用程序提供应用编程接口(application programming interface，API)和编程框架。应用程序框架层包括一些预先定义的函数。
如图3A所示，应用程序框架层可以包括窗口管理器，内容提供器，视图***，电话管理器，资源管理器，通知管理器等。
窗口管理器用于管理窗口程序。窗口管理器可以获取显示屏大小，判断是否有状态栏，锁定屏幕，截取屏幕等。
内容提供器用来存放和获取数据，并使这些数据可以被应用程序访问。所述数据可以包括视频，图像，音频，拨打和接听的电话，浏览历史和书签，电话簿等。
视图***包括可视控件，例如显示文字的控件，显示图片的控件等。视图***可用于构建应用程序。显示界面可以由一个或多个视图组成的。例如，包括短信通知图标的显示界面，可以包括显示文字的视图以及显示图片的视图。
电话管理器用于提供电子设备100的通信功能。例如通话状态的管理(包括接通，挂断等)。
资源管理器为应用程序提供各种资源，比如本地化字符串，图标，图片，布局文件，视频文件等等。
通知管理器使应用程序可以在状态栏中显示通知信息，可以用于传达告知类型的消息，可以短暂停留后自动消失，无需用户交互。比如通知管理器被用于告知下载完成，消息提醒等。通知管理器还可以是以图表或者滚动条文本形式出现在***顶部状态栏的通知，例如后台运行的应用程序的通知，还可以是以对话窗口形式出现在屏幕上的通知。例如在状态栏提示文本信息，发出提示音，电子设备振动，指示灯闪烁等。
本申请实施例中，应用程序框架层中活动内容管理服务(Activity Manager Service，AMS)、窗口管理服务(Window Manager Service，WMS)和下载管理服务(Download Manager Service，DMS)中还可以包括应用保活模块、事件注入模块、虚拟屏幕管理模块。
其中，应用保活模块，用于在具有多屏显示模式功能的应用启动之后，控制电子设备进入VR多屏显示模式。在该模式下，电子设备可以同时运行多个应用，并支持各应用同时处于活动状态。
事件注入模块，用于在多屏显示模式下，获取用户的操作对应事件，并将事件分发到应用对应的虚拟屏幕上。
虚拟屏幕管理模块，用于为电子设备提供创建虚拟屏幕和销毁虚拟屏幕的能力。
Android Runtime包括核心库和虚拟机。Android runtime负责安卓***的调度和管理。

如图3B所示，本申请实施例中，VR场景显示适配模块(HwVRDisplayAdaper)实现在多屏模式下创建虚拟屏幕和销毁虚拟屏幕，实现对虚拟屏幕的管理，并为其它服务(例如显示管理模块(DisplayManager)、显示管理全局模块(DisplayManagerGlobal)和显示管理服务模块(DisplayManagerService)等)开放创建虚拟屏幕接口(createVRDisplay{})和销毁虚拟屏幕接口(destroyVRDisplay{})。显示管理模块、显示管理全局模块和显示管理服务模块通过层层调用创建虚拟屏幕接口完成在进入VR多屏显示模式时创建虚拟屏幕的功能，另外显示管理模块、显示管理全局模块和显示管理服务模块通过层层调用创建虚拟屏幕接口完成在退出VR多屏显示模式下销毁虚拟屏幕的功能。在图3B中，显示管理服务模块会在电子设备的开机初始化时注册创建虚拟屏幕所需的回调，即显示管理服务模块先通过调用注册VR场景显示适配模块的接口(registerVRDisplayAdapterLoked{})，然后调用注册接口(registerLocked{})完成注册创建虚拟屏幕。
如图3C所示，本申请实施例中，Android支持对指定的屏幕注入事件，并自定义接口将该屏幕注入事件能力开放给其它服务。图3C中，输入管理模块(IputManager)依次调用injectInputEvent(event,mode,displayid)接口、injectInputEventToDisplay(event,mode,displayid)接口、injectInputEventInternal(event,displayId,mode))接口注入事件到指定虚拟屏幕。
如背景技术所述，局限于电子设备的屏幕大小，电子设备采用画中画模式虽然能够同时显示两个应用的活动内容，但是可能会造成内容的遮挡，所以多窗口功能的用户体验不好。另外，目前电子设备也已经支持分屏模式，分屏模式也是可以支持两个应用同时处于活动状态，例如，如图4所示，手机显示屏的上半部分窗口显示图库应用的照片，显示屏的下半部分窗口显示微信聊天的画面，当用户在查看照片的同时，微信聊天的画面会正常显示。但是分屏模式下，每个应用受限于屏幕大小，能够显示的内容是有限的，用户体验不佳。为此，本申请实施例提供一种VR多屏显示方法，该方法可以由与虚拟现实显示设备连接的电子设备执行，该方法对应的多屏显示算法可集成于支持VR的应用中，具体步骤参见图5。
步骤501，电子设备接收用户在支持VR的应用中的第一操作。
示例性地，如图6所示，支持VR的应用的名称可以是VR眼镜应用，当电子设备检测到用户作用于VR眼镜应用图标601时，则VR眼镜显示如图11A所示的界面。或者当电子设备检测到与VR眼镜建立连接时，则VR眼镜显示如图11A所示的界面。这时电子设备可以处于灭屏状态，以节省电量。
若用户希望在VR场景中显示多个应用时，则点击图11A所示的界面中的VR多屏显示控件1101，因此电子设备接收用户作用于VR多屏显示控件1101的点击操作。
步骤502，响应于第一操作，电子设备从当前的VR模式切换至VR多屏显示模式。
示例性地，当用户点击VR多屏显示控件1101时，电子设备从当前的VR模式切换至VR多屏显示模式。也就是说，电子设备启动VR多屏显示功能，即电子设备可以同时将处于活动状态的多个应用的内容分别绘制到VR眼镜的不同虚拟屏幕上。
步骤503，电子设备接收用户作用于第一应用图标的第二操作，和接收用户作用于第二应用图标的第三操作。
示例性地，当用户点击VR眼镜应用中预先加载的微博应用的图标时，电子设备接收到用户作用于微博应用图标的第二操作；当用户点击VR眼镜应用中预先加载的抖音应用的图标时，电子设备接收到用户作用于抖音应用图标的第三操作。
步骤504，响应于该第二操作和第三操作，电子设备分别创建与第一应用对应的第一虚拟屏幕和与第二应用对应的第二虚拟屏幕，并在第一虚拟屏幕上显示第一应用的内容，在第二虚拟屏幕上显示第二应用的内容。
也就是说，电子设备为各个应用分别创建对应的虚拟屏幕，并在虚拟屏幕上显示该应用的内容。示例性，第一虚拟屏幕显示微博应用的界面，第二虚拟屏幕显示抖音应用的界面。
可见，用户通过该支持VR的应用，可以将电子设备的内容投屏到VR眼镜中，并且可以同时在不同的虚拟屏幕上分别显示不同的应用的界面，用户可以进入VR游戏，也可以同时观看全景图片等，在VR眼镜中能够同时观看照片、视频、和游戏等，享受更大屏幕的VR体验。
其中，电子设备图3A至图3C所示的功能模块，实现虚拟屏幕的创建，以及获取第一应用的内容和第二应用的内容，并将第一应用的内容和第二应用的内容一起绘制到画布上，完成完成画面的畸变处理，并将畸变处理后的图像显示在VR眼镜的显示器上，这样用户就可以通过VR眼镜同时观看到两个应用的内容。
需要说明的是，之所以需要对画面进行畸变处理，是因为VR原理如图7所示，电子设备把正常的画面通过畸变算法变成图中左边部分形状，然后再通过VR眼镜(透镜)的光学作用将画面恢复成图中右边部分形状，这样在VR眼镜中看到内容是符合现实效果的。
本申请实施例中，***框架层所提供的创建虚拟屏幕的能力可以支持电子设备将虚拟屏幕创建到电子设备的屏幕上，当用户启动多个应用并显示到这些应用的虚拟屏幕时，这时应用的内容还是显示在电子设备屏幕上，内容不能超出电子设备的屏幕大小，必然存在被缩小显示，甚至可能存在部分被遮挡的问题。例如，如图8左侧显示，第一应用的显示界面为界面A，第二应用的显示界面为界面B，界面A和界面B在同一个平面屏幕上显示。为了实现在VR场景中多屏显示，电子设备通过录屏的接口获取多个虚拟屏幕的显示内容，然后将多个虚拟屏幕的内容统一绘制VR场景的3D屏幕上，然后完成画面的畸变处理，最终可以显示在VR的眼镜中。例如，如图8右侧显示，第一应用的显示界面为界面A和第二应用的显示界面为界面B被畸变处理，并被复制成两个相同画面内容，以便于用户通过VR眼镜进行观看。
在一种可能的实施例中，当电子设备进入VR多屏显示模式后，电子设备的屏幕可以处于灭屏状态，以达到节省电量的目的。例如，用户可以点击手柄应用，根据应用提示，通过蓝牙将手机连接上手柄，如图9所示，当用户使用数据线连接电子设备与VR眼镜后，用户戴上VR眼镜，电子设备就处于灭屏状态，用户通过手柄继续操作。
具体地，如图10所示，手柄包括触控板、返回键、音量键、HOME(主菜单)键、指示灯和扳机键等硬件结构。其中，各个部件的具体的功用如表1所示。
表1
Figure PCTCN2020092207-appb-000002
由表1可见，当用户按住触控板并移动手柄，可以进行滑动操作；当用户轻触手柄上的触控板时可以进行点击操作，当用户短按HOME键可以返回手机的待机界面。
在一种可能的实施例中，当电子设备通过手柄接收到用户的退出操作时，电子设备从VR多屏显示模式切换为VR模式，并清除所创建的虚拟屏幕。例如，当用户长按Home键时，或者当用户摘下VR眼镜时，电子设备就从VR多屏显示模式切换为VR模式，并清除所创建的虚拟屏幕。
以下将结合附图和实际应用场景，对本申请实施例提供的VR多屏显示方法进行举例说明，具体步骤参见图12。
步骤701，电子设备与VR建立连接，如图9所示，用户使用VR眼镜前，使用数据线连接手机与VR眼镜，然后根据提示下载个安装VR眼镜应用，以及手柄应用。然后用户佩戴虚拟眼镜，调节头箍带，以保证双眼对准镜片中心。若屏幕不清晰时，用户可以旋转瞳孔间距调节轮或上下左右调整虚拟眼镜的佩戴位置使得画面清晰。
步骤702，当VR眼镜连接上手机，电子设备接收用户的操作，进入VR眼镜应用。示例性地，图11A为用户戴上VR眼镜中看到的内容，用户可以通过操作手柄点击VR多屏显示控件1101，然后电子设备退出当前的VR模式，启动VR多屏显示模式。
步骤703，电子设备接收用户的第一操作，退出VR模式，进入VR多屏显示模式。
步骤704，VR眼镜在VR多屏显示模式对应的VR场景中加载显示了若干个应用图标，如图11B所示，界面中包括抖音的应用图标1102和微博的应用图标1103。
步骤705至步骤707，电子设备接收用户作用于第一应用图标的第二操作，和接收用户作用于第二应用图标的第三操作，电子设备分别创建与第一应用对应的第一虚拟屏幕和与第二应用对应的第二虚拟屏幕，在第一虚拟屏幕上显示第一应用的内容，在第二虚拟屏幕上显示第二应用的内容。
示例性地，如图11B所示，当用户点击抖音的应用图标1102时，电子设备创建虚拟屏幕，并将所获取的抖音的内容渲染到该虚拟屏幕上。如图11C所示，当用户点击微博的应用图标1103时，电子设备创建虚拟屏幕，并将所获取的微博的内容渲染到该虚拟屏幕1104上。最终，电子设备所生成的VR场景的画布上显示左右眼部分，每个部分均全屏显示有微博应用的显示内容和抖音应用的显示内容，如图11D中的1105和1106。
在步骤707之后，若用户摘下眼镜，或者用户长按手柄的HOME键，则电子设备退出VR多屏显示模式，并清除所创建的虚拟屏幕。
本申请实施例中，电子设备可以实现在三维空间的虚拟环境中的不同虚拟屏幕上分别显示多个应用的显示界面，不仅画面不会发生遮挡，VR眼镜200显示的画面更大更清晰，增强了用户的视觉体验。
