下面将参照附图更详细地描述本公开的实施例。虽然附图中显示了本公开的某些实施例，然而应当理解的是，本公开可以通过各种形式来实现，而且不应该被解释为限于这里阐述的实施例，相反提供这些实施例是为了更加透彻和完整地理解本公开。应当理解的是，本公开的附图及实施例仅用于示例性作用，并非用于限制本公开的保护范围。
应当理解，本公开的实施方式中记载的步骤可以按照不同的顺序执行，和/或并行执行。此外，实施方式可以包括附加的步骤和/或省略执行示出的步骤。本公开的范围在此方面不受限制。
本文使用的术语“包括”及其变形是开放性包括，即“包括但不限于”。术语“基于”是“至少部分地基于”。术语“一个实施例”表示“至少一个实施例”；术语“另一实施例”表示“至少一个另外的实施例”；术语“一些实施例”表示“至少一些实施例”。术语“响应于”以及有关的术语是指一个信号或事件被另一个信号或事件影响到某个程度，但不一定是完全地或直接地受到影响。如果事件x“响应于”事件y而发生，则x可以直接或间接地响应于y。例如，y的出现最终可能导致x的出现，但可能存在其它中间事件和/或条件。在其它情形中，y可能不一定导致x的出现，并且即使y尚未发生，x也可能发生。此外，术语“响应于”还可以意味着“至少部分地响应于”。
术语“确定”广泛涵盖各种各样的动作，可包括获取、演算、计算、处理、推导、调研、查找(例如，在表、数据库或其他数据结构中查找)、探明、和类似动作，还可包括接收(例如，接收信息)、访问(例如，访问存储器中的数据)和类似动作，以及解析、选择、选取、建立和类似动作等等。其他术语的相关定义将在下文描述中给出。其他术语的相关定义将在下文描述中给出。
需要注意，本公开中提及的“第一”、“第二”等概念仅用于对不同的装置、模块或单元进行区分，并非用于限定这些装置、模块或单元所执行的功能的顺序或者相互依存关 系。
需要注意，本公开中提及的“一个”、“多个”的修饰是示意性而非限制性的，本领域技术人员应当理解，除非在上下文另有明确指出，否则应该理解为“一个或多个”。
为了本公开的目的，短语“A和/或B”意为(A)、(B)或(A和B)。
本公开实施方式中的多个装置之间所交互的消息或者信息的名称仅用于说明性的目的，而并不是用于对这些消息或信息的范围进行限制。
本公开一个或多个实施例提供的信息交互方法采用扩展现实(Extended Reality，简称XR)技术。扩展现实技术可以通过计算机将真实与虚拟相结合，为用户提供可人机交互的虚拟现实空间。在虚拟现实空间中，用户可以通过例如头盔式显示器(Head Mount Display，HMD)等虚拟现实设备，进行社交互动、娱乐、学习、工作、远程办公、创作UGC(User Generated Content，用户生成内容)等。
本公开实施例记载的虚拟现实设备可以包括但不限于如下几个类型：
电脑端虚拟现实(PCVR)设备，利用PC端进行虚拟现实功能的相关计算以及数据输出，外接的电脑端虚拟现实设备利用PC端输出的数据实现虚拟现实的效果。
移动虚拟现实设备，支持以各种方式(如设置有专门的卡槽的头戴式显示器)设置移动终端(如智能手机)，通过与移动终端有线或无线方式的连接，由移动终端进行虚拟现实功能的相关计算，并输出数据至移动虚拟现实设备，例如通过移动终端的APP观看虚拟现实视频。
一体机虚拟现实设备，具备用于进行虚拟功能的相关计算的处理器，因而具备独立的虚拟现实输入和输出的功能，不需要与PC端或移动终端连接，使用自由度高。
当然虚拟现实设备实现的形态不限于此，可以根据需要可以进一步小型化或大型化。
虚拟现实设备中设置有姿态检测的传感器(如九轴传感器)，用于实时检测虚拟现实设备的姿态变化，如果用户佩戴了虚拟现实设备，那么当用户头部姿态发生变化时，会将头部的实时姿态传给处理器，以此计算用户的视线在虚拟环境中的注视点，根据注视点计算虚拟环境的三维模型中处于用户注视范围(即虚拟视场)的图像，并在显示屏上显示，使人 仿佛在置身于现实环境中观看一样的沉浸式体验。
图2示出了本公开一实施例提供的虚拟现实设备的虚拟视场的一个可选的示意图，使用水平视场角和垂直视场角来描述虚拟视场在虚拟环境中的分布范围，垂直方向的分布范围使用垂直视场角BOC表示，水平方向的分布范围使用水平视场角AOB表示，人眼通过透镜总是能够感知到虚拟环境中位于虚拟视场的影像，可以理解，视场角越大，虚拟视场的尺寸也就越大，用户能够感知的虚拟环境的区域也就越大。其中，视场角，表示通过透镜感知到环境时所具有的视角的分布范围。例如，虚拟现实设备的视场角，表示通过虚拟现实设备的透镜感知到虚拟环境时，人眼所具有的视角的分布范围；再例如，对于设置有摄像头的移动终端来说，摄像头的视场角为摄像头感知真实环境进行拍摄时，所具有的视角的分布范围。
虚拟现实设备，例如HMD集成有若干的相机(例如深度相机、RGB相机等)，相机的目的不仅仅限于提供直通视图。相机图像和集成的惯性测量单元(IMU)提供可通过计算机视觉方法处理以自动分析和理解环境的数据。还有，HMD被设计成不仅支持无源计算机视觉分析，而且还支持有源计算机视觉分析。无源计算机视觉方法分析从环境中捕获的图像信息。这些方法可为单视场的(来自单个相机的图像)或体视的(来自两个相机的图像)。它们包括但不限于特征跟踪、对象识别和深度估计。有源计算机视觉方法通过投影对于相机可见但不一定对人视觉系统可见的图案来将信息添加到环境。此类技术包括飞行时间(ToF)相机、激光扫描或结构光，以简化立体匹配问题。有源计算机视觉用于实现场景深度重构。
参考图3，图3示出了本公开一实施例提供的信息交互方法100的流程图，方法100包括步骤S120-步骤S160。
步骤S120：接收复合视频配置信息；所述复合视频配置信息包括虚拟现实空间信息、与所述虚拟现实空间信息对应的至少一个子虚拟现实空间信息、以及与所述子虚拟现实空间信息对应的视频配置信息。
在一些实施例中，虚拟现实空间信息用于标识虚拟现实空间所呈现的内容。示例性地， 以视频直播为例，虚拟现实空间信息可以为视频直播的场景名称，例如，若一虚拟直播空间用于直播节目A，则与该虚拟直播空间对应的虚拟现实空间信息可以为“节目A”。
在一个具体实施方式中，可以在服务端预先为拟播放的视频内容(例如节目A)配置相应的虚拟现实空间，该虚拟现实空间可以具有两个以上的子虚拟现实空间，每个子虚拟现实空间可以配置一个或多个视频流，不同的子虚拟现实空间中显示的视频可以提供同一对象(例如同一个节目)的不同的视频观看视角，例如舞台观看视角、近景观看视角、远景观看视角。配置完成后，服务端可以将与该虚拟现实空间对应的虚拟现实空间信息(例如场景名称、场景ID)、关于该虚拟现实空间具有几个子虚拟现实空间的信息、以及关于每个子虚拟现实空间所对应的视频配置信息，下发到客户端。
在一些实施例中，服务端将复合视频配置信息下发到客户端后，客户端可以将该复合视频配置信息转换为预设的标准格式。在本实施例中，客户端通过将接收到的复合视频配置信息统一转换为预设的标准格式，可以使客户端可以兼容和适配不同格式或版本的复合视频配置信息。
在一些实施例中，视频配置信息包括视频呈现方式信息，所述视频呈现方式信息包括如下中的一种或多种：屏幕形状信息、屏幕数量信息、视频维度类型信息、虚拟摄像机信息。
示例性地，视频呈现方式信息可以用于描述用于在子虚拟现实空间内呈现视频的屏幕的数量、各个屏幕的形状、各个屏幕对应的视频维度类型(或3D视频或2D视频)以及虚拟摄像机信息。其中，3D视频可以包括但不限于矩形3D视频、半景3D视频、全景3D视频或鱼眼3D视频。虚拟摄像机是在虚拟现实环境中用来模拟用户所能看到的视角、视野的工具，虚拟摄像机信息包括但不限于焦距、成像视角，空间位置等。
在一些实施例中，视频配置信息包括视频流信息。示例性地，视频流可以采用H.265、H.264、MPEG-4等编码格式。
在一些实施例中，虚拟现实空间可以是对真实世界的仿真环境，也可以是半仿真半虚构的虚拟场景，还可以是纯虚构的虚拟场景。虚拟场景可以是二维虚拟场景、2.5维虚拟 场景或者三维虚拟场景中的任意一种，本申请实施例对虚拟场景的维度不加以限定。例如，虚拟场景可以包括天空、陆地、海洋等，该陆地可以包括沙漠、城市等环境元素，用户可以控制虚拟对象在该虚拟场景中进行移动。
参考图1，用户可以通过例如头戴式VR眼镜等智能终端设备进入虚拟现实空间，并在虚拟现实空间中控制自己的虚拟角色(Avatar)与其他用户控制的虚拟角色进行社交互动、娱乐、学习、远程办公等。
在一个实施例中，在虚拟现实空间中，用户可以通过控制器来实现相关的交互操作，该控制器可以为手柄，例如用户通过对手柄的按键的操作来进行相关的操作控制。当然在另外的实施例中，也可以不使用控制器而使用手势或者语音或者多模态控制方式来对虚拟现实设备中的目标对象进行控制。
在一些实施例中，所述虚拟现实空间包括虚拟直播空间。在虚拟直播空间中，观众用户可以控制虚拟角色(Avatar)以诸如第一人称视角或第三人称视角等观看视角，观看表演者的直播视频。
步骤S140：确定虚拟现实空间中用户所在位置的目标子虚拟现实空间。
在一些实施例中，响应于用户触发的使用户控制的虚拟角色进入目标子虚拟现实空间的指令，确定虚拟现实空间中用户所在位置的目标子虚拟现实空间。
示例性地，用户可以控制虚拟角色在子虚拟现实空间内移动，并通过预设的指令使用户所控制的虚拟角色在不同的子虚拟现实空间中进行切换。
在一个具体实施方式中，可以在各子虚拟现实空间中设置传送点，当用户控制其虚拟角色靠近或触碰该传送点时，则将该虚拟角色传入与该传送点对应的目标子虚拟现实空间中。
步骤S160：基于所述复合视频配置信息确定与所述目标子虚拟现实空间对应的视频配置信息，并基于所确定的视频配置信息在所述目标子虚拟现实空间中呈现视频内容。
示例性地，当用户控制虚拟角色由子虚拟现实空间A进入子虚拟现实空间B后，则客户端可以基于预先接收到的与子虚拟现实空间B对应的视频配置信息进行视频渲染， 从而可以向用户呈现子虚拟现实空间B提供的视频内容。
在一些实施例中，可以基于与目标子虚拟空间对应的视频配置信息，确定与该目标子虚拟空间对应的视频呈现方式，例如屏幕的数量、屏幕的形状、与屏幕对应的视频的维度类型(例如3D视频或2D视频)，进而在该目标子虚拟空间创建相应的屏幕并渲染视频。
根据本公开的一个或多个实施例，通过接收复合视频配置信息，并使所述复合视频配置信息包括虚拟现实空间信息、与所述虚拟现实空间信息对应的至少一个子虚拟现实空间信息、以及与所述子虚拟现实空间信息对应的视频配置信息，进而可以基于接收到的复合视频配置信息确定与所述目标子虚拟现实空间对应的视频配置信息并在目标子虚拟现实空间中呈现对应的视频内容，从而可以在客户端搭建多样化的视频呈现场景，可以使用户获得丰富和多样的观看体验。
在一些实施例中，在同一虚拟现实空间中，不同的子虚拟现实空间中显示的视频可以提供同一对象(例如同一个节目)的不同的视频观看视角，例如舞台观看视角、近景观看视角、远景观看视角。
示例性地，以在虚拟现实空间中直播晚会为例进行示例性说明。参考图4，可以在虚拟现实空间中设置对应的舞台观看视角的子虚拟现实空间A，对应近景观看视角的子虚拟空间B和C，以及对应远景观看视角的子虚拟现实空间D。相应地，当用户操控虚拟角色进入子虚拟现实空间A后，可以在子虚拟现实空间A观看从舞台拍摄到的晚会画面；当用户操控虚拟角色进入子虚拟现实空间B或C后，可以在子虚拟现实空间B或C观看从靠近舞台处拍摄到的晚会画面；用户操控虚拟角色进入子虚拟现实空间D后，可以在子虚拟现实空间D观看从相对远离舞台处拍摄到的晚会画面。因此，用户可以根据自身需求体验不同的观看视角，从而可以在虚拟现实空间中体验到真实的现场观看体验。在一个具体实施方式中，子虚拟现实空间A可以位于虚拟现实空间设置的舞台区，子虚拟现实空间B、C和D位于虚拟现实空间设置的观众区。
在一个具体实施方式中，不同子虚拟现实空间所对应的视频流能够提供来自具有不同的拍摄角度或拍摄机位的摄像装置所捕获的视频内容。
在一些实施例中，同一子虚拟现实空间对应两个以上视频配置信息。示例性地，可以在一个子虚拟现实空间设置一个主屏和多个副屏。主屏和副屏可以对应不同的视频流、不同的屏幕形状、不同的视频维度类型。例如，可以在主屏上播放3D全景视频，在副屏上播放2D视频。
在一些实施例中，不同的子虚拟现实空间中的主屏可以用于呈现具有不同观看视角的视频内容，不同的子虚拟现实空间中的副屏可以用于呈现具有相同的观看视角的视频内容。
在一些实施例中，可以在不同的虚拟现实空间呈现不同的视频呈现环境，所述视频呈现环境包括如下中的一个或多个：舞台、布景、灯光、道具、特效元素、舞美。示例性地，可以通过不同的虚拟现实空间播放不同的视频内容，例如不同的节目内容、不同的主播、不同的晚会等，不同的虚拟现实空间具有不同的舞台布景、灯光舞美、动画特效等。
在一个具体实施方式中，可以为不同的虚拟现实空间配置不同的用于呈现视频呈现环境的动画资源(例如贴图、动画模型、光影特效等)，该动画资源可以预先存储与客户端中，以供用户进入某一虚拟现实空间后渲染对应的视频呈现环境。
在一些实施例中，视频配置信息包括直播阶段信息，所述直播阶段信息包括如下中的一种或多种：直播前阶段、直播中阶段、直播后阶段。示例性地，对于不同的直播阶段，可以在虚拟现实空间中展现不同的舞台布景、灯光舞美、动画特效，从而可以使用户获得丰富的观看体验。
相应地，根据本公开一实施例提供了一种信息交互装置，包括：
信息接收单元，用于接收复合视频配置信息；所述复合视频配置信息包括虚拟现实空间信息、与所述虚拟现实空间信息对应的至少一个子虚拟现实空间信息、以及与所述子虚拟现实空间信息对应的视频配置信息；
子空间确定单元，用于确定虚拟现实空间中用户所在位置的目标子虚拟现实空间；
显示单元，用于基于所述复合视频配置信息确定与所述目标子虚拟现实空间对应的视频配置信息，并基于所确定的视频配置信息在所述目标子虚拟现实空间中呈现视频内容。
在一些实施例中，在同一虚拟现实空间中不同的子虚拟现实空间所对应的视频配置信 息能够提供针对同一对象的不同观看视角。
在一些实施例中，所述观看视角包括如下中的一个或多个：舞台观看视角、近景观看视角、远景观看视角。
在一些实施例中，同一子虚拟现实空间对应两个以上视频配置信息。
在一些实施例中，所述两个以上视频配置信息包括用于呈现3D视频图像的视频配置信息和用于呈现2D视频图像的视频配置信息。

对于装置的实施例而言，由于其基本对应于方法实施例，所以相关之处参见方法实施例的部分说明即可。以上所描述的装置实施例仅仅是示意性的，其中作为分离模块说明的模块可以是或者也可以不是分开的。可以根据实际的需要选择其中的部分或者全部模块来实现本实施例方案的目的。本领域普通技术人员在不付出创造性劳动的情况下，即可以理解并实施。
