具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象， 而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的信息提示方法、信息提示装置、电子设备和可读存储介质进行详细地说明。
本申请实施例提供的信息提示方法，该信息提示方法的执行主体可以包括但不限于穿戴设备，穿戴设备的类型可以是VR设备、AR设备或MR设备等，在此不做具体限定。
需要说明的是，穿戴设备为在使用时需要封闭用户视觉的头戴式显示设备。
通常穿戴设备设置有内侧显示屏，内侧显示屏为穿戴设备的穿戴者可以看到的显示区域。在本实施例中，可以在穿戴设备外侧增加显示装置，即在穿戴设备外侧设置外侧显示屏，外侧显示屏为非穿戴者可以看到的显示区域。
图1是本申请的一些实施例提供的信息提示方法的流程示意图。如图1所示，该信息提示方法包括：步骤110和步骤120。
步骤110、接收第一输入，第一输入用于启动穿戴设备的***。
在本申请实施例中，上述第一输入用于启动穿戴设备的***。***可以让用户在不摘除穿戴设备的情况下，实现与外部现实世界的行为交互。
本申请中的***指的是视频透视(VST，Video See-Through)，视频透视是通过拍摄装置捕捉到真实世界的实时视图，然后与计算机图像技术结合在一起，将实时视图展示在不透明的显示器上，最终进入用户视野。
穿戴设备的***可以给穿戴者提供一种人眼能够直接透过穿戴设备看到周围真实世界的感觉，因此，该功能被称为“透视”。
在本步骤中，第一输入可以是用户对穿戴设备的输入，也可以是用户对穿戴设备连接的其他电子设备的输入，还可以是其他电子设备对穿戴设备的输入。
其中，用户可以是穿戴设备的穿戴者，也可以是非穿戴者，在此不作具体限定；其他电子设备可以是智能手表、智能手环、手柄、手机或电脑等。
示例性地，上述第一输入包括但不限于：用户通过触摸屏或实体按键等触控装置对穿戴设备的触控输入，或者为用户输入的语音指令，或者为用户输入的特定手势，或者为其他电子设备对穿戴设备输入的启动指令，或者为其他可行性输入，具体的可以根据实际使用需求确定，本申请实施例不作限定。
本申请实施例中的触控输入包括但不限于：对穿戴设备的点击输入、滑动输入、按压输入或对穿戴设备连接的其他控制设备的触控输入等。上述的点击输入可以为单击输入、双击输入或任意次数的点击输入等，还可以为长按输入或短按输入。
例如，穿戴设备或连接的其他电子设备的触摸屏上设置有与***对应的目标控件， 上述的第一输入可以为：用户对目标控件的点击输入；或者可以为：穿戴设备或连接的其他电子设备上设置有与***对应的实体按键或可以选择***的实体按键，上述的第一输入可以为：用户对实体按键的按压输入等。
本申请实施例中的语音指令包括但不限于：穿戴设备在接收到语音如“启动透视”或“打开透视”时，触发启动穿戴设备的***。
本申请实施例中的特定手势包括但不限于：单击手势、滑动手势、拖动手势、压力识别手势、长按手势、面积变化手势、双按手势、双击手势中的任意一种，上述预定手势可以与***对应；例如，上述的第一输入可以为：穿戴设备在检测到用户的预定手势时，启动***。
本申请实施例中的其他电子设备对穿戴设备输入的启动指令，可以是在其他电子设备设置有启动指令，可以直接触发穿戴设备启动***；例如，上述第一输入可以为：某一电子设备设置有定时的启动指令，在到达指定时刻时，该电子设备自动向穿戴设备发送启动指令，穿戴设备在接收到启动指令后就会启动***。
当然，在其他实施例中，第一输入也可以为其他形式，包括但不限于字符输入、指纹输入或虹膜输入等，具体可根据实际需要决定，本申请实施例对此不作限定。
在一些实施例中，***可以通过启动穿戴设备的拍摄功能来完成，拍摄功能可以通过在穿戴设备的外侧显示屏设置的摄像头来开启。
在启动穿戴设备的***之后，穿戴设备的穿戴者可以直接看到真实环境中的人和物，并可以对真实环境进行拍摄图像或录制视频，甚至可以进行人脸信息的采集。穿戴者通过穿戴设备可以随意拍摄进入镜头的人或物，周围其他非穿戴者可能在不知情的情况下被偷拍。在这个过程中，更大的隐私泄露风险在于拍摄的图像或人脸识别信息会被上传至穿戴设备对应的服务器中，非穿戴者的信息可能被随意使用。可以理解的是，在关闭穿戴设备的***之后，穿戴者只能看到内侧显示屏显示的内容。
可以理解的是，穿戴设备的***可以与外侧显示屏的摄像头相关联。即可以实时监测外侧显示屏的摄像头是否处于开启状态。若外侧显示屏的摄像头开启，则确定穿戴设备的***也开启；若外侧显示屏的摄像头关闭或睡眠，则确定穿戴设备的***未开启；
***是指通过相机采集周围环境的实时视图并通过屏幕进行显示，给人一种人眼能够直接透过头显看到周围真实世界的感觉，因此被称为“透视”功能。
步骤120、响应于第一输入，在穿戴设备的外侧显示屏，显示目标提示信息，目标提示信息用于指示穿戴设备的***已开启。
而在本申请实施例中，由于穿戴设备设置有外侧显示屏，其他用户可以通过外侧显示屏显示的目标提示信息判断穿戴设备的工作状态。
图2是本申请的一些实施例提供的信息提示方法的显示区域示意图。
如图2所示，穿戴设备可以包括外侧显示屏210、内侧显示屏220以及固定结构 240。
外侧显示屏210可以为给非穿戴者展示内容的外屏幕显示区域，内侧显示屏220可以为给穿戴者展示内容的内屏幕显示区域。固定结构用于对外侧显示屏210和内侧显示屏220进行固定连接。
在实际执行中，在穿戴设备启动之后，穿戴设备可以实时检测***是否处于开启状态。若接收第一输入后，确定***处于已开启状态，则可以响应于第一输入，把开启状态信息传给穿戴设备的外侧显示屏，然后可以在外侧显示屏显示用于指示***已开启的目标提示信息。
若确定***处于未开启状态，外侧显示屏可以关闭内容显示界面，或者显示空白图像，或者显示文本信息“***未开启”等，在此不作具体限定。
如图3所示，穿戴设备包括外侧显示屏310和头部固定装置320。头部固定装置320用于将穿戴设备固定于穿戴者的头部。头部固定装置320可以包括连接外侧显示屏310横向两端的横向头带和连接外侧显示屏310上部与横向头带的纵向头带，图3中的头部固定装置320仅用作示例，本申请对此结构不作具体限定。
在穿戴设备未开启***的情况下，在外侧显示屏310不显示目标提示信息或者是显示空白图像。
在穿戴设备的穿戴者处于公共环境下，非穿戴者可以通过穿戴设备的外侧显示屏上显示的目标提示信息，及时获知该穿戴设备有没有开启***。
例如：穿戴者在商场中体验VR设备，在穿戴者开启VR设备的***时，VR设备的外侧显示屏将显示目标提示信息。那么在其他人经过穿戴者周围时，可以第一时间知道穿戴者是否正在使用VR设备的***。其他人为了防止自己被偷拍，可以选择远离该穿戴者。
根据本申请实施例提供的信息提示方法，通过在穿戴设备启动***的情况下，在穿戴设备的外侧显示屏显示目标提示信息，可以直观地呈现穿戴设备已开启***，让处于与穿戴设备的穿戴者处于同一真实场景下的非穿戴者通过外侧显示屏及时知道穿戴设备的使用状态，从而最大程度地保障了非穿戴者的隐私安全。
在一些实施例中，目标提示信息包括以下至少一项：
文本提示信息；
虚拟对象的部分面部图像或完整面部图像；
穿戴设备的穿戴者的面部图像，面部图像包括穿戴者的部分人脸图像或完整人脸图像；
场景图像，场景图像为穿戴设备所处的现实场景的二维场景图像或三维场景图像。
可以理解的是，目标提示信息可以是上述至少一种信息的组合。例如：目标提示信息可以是文本提示信息和虚拟对象的面部图像的组合信息，或者是文本提示信息和穿戴设备的穿戴者的面部图像的组合信息，或者是文本提示信息和场景图像的组合信 息等。
可以通过图像处理技术将至少两种信息进行拼接和组合，过多的信息组合可能会影响目标提示信息的提示效果，通常情况下，可以采用一种目标提示信息或两种信息组合的目标提示信息。
如图4所示，在穿戴设备的***已开启的情况下，在穿戴设备的外侧显示屏同时显示了文本提示信息和虚拟对象的部分面部图像。
在目标提示信息包括文本提示信息的情况下，文本提示信息可以是表征“***已开启”含义的预设文本信息，即非穿戴者可以直接通过文本提示信息获得“***已开启”的提示。
可以理解的是，预设文本信息可以为默认设置的文本信息，例如：默认文本信息可以是“***已开启”；或者是根据用户需求设置的个性化文本信息，例如：文本提示信息可以设置为“摄像头已开启，我在看你”；或者是“摄像头开启，正在扫视周围环境”；或者是其他可以表征***已开启的文本信息，在此不作具体限定。
本申请实施例也不对文本提示信息的文字显示形式进行具体限定。
如图5所示，在穿戴设备的***已开启的情况下，在穿戴设备的外侧显示屏显示文本提示信息“摄像头已开启，我在看你”。
在目标提示信息包括预设标识图像的情况下，预设标识图像可以是预先设置的特定含义的图像，特定含义的图像可以是用于表征***开启的标识图像。
例如：预设标识图像可以采用“相机”标识图像表示***已开启，或者“打开”标识图像，表示***已开启，例如：标识“√”；若穿戴设备未开启***，则预设标识图像可以采用“关闭”标识图像等，例如：标识“×”。
如图6所示，在穿戴设备的***已开启的情况下，在穿戴设备的外侧显示屏显示“相机”标识图像。
在目标提示信息包括穿戴设备的穿戴者的面部图像的情况下，穿戴者的面部图像可以包括穿戴者的部分人脸图像或完整人脸图像。穿戴者的部分人脸图像为包含穿戴者的至少一个人脸部位的面部图像，穿戴者的完整人脸图像为包含穿戴者的全部人脸部位的面部图像。例如：穿戴者的部分人脸图像可以是穿戴者的眼部图像、嘴部图像或侧脸图像等，完整人脸图像即为包含穿戴者五官的全脸图像。
穿戴者的面部图像可以是基于穿戴者的面部特征生成的图像。如图2所示，穿戴设备还可以包括脸部追踪感应器230。脸部追踪感应器230可以由摄像头群组、红外光装置或结构光装置组成，用于采集面部特征数据。
在实际执行中，摄像头群组可以用于追踪佩戴者的脸部，并且可以对人脸中的每个部位进行特征点采集和定位，还可以采集人脸色彩信息以及人脸光影信息，红外光装置可以采集人脸红外图像，结构光装置可以采集人脸深度图像。由摄像头群组、红外光装置或结构光装置采集的数据共同组成了面部特征数据。
穿戴设备中的图形处理器(Graphics Processing Unit，GPU)可以对脸部追踪感应器230采集的面部特征数据进行处理，生成穿戴者的部分人脸图像或完整人脸图像。
GPU还可以对面部特征数据进行实时渲染和重构，得到包含表情动作信息的面部图像，使得外侧显示屏显示的穿戴者的面部图像更加生动形象。
在实际执行中，在穿戴设备的外侧显示屏显示穿戴者的面部图像的情况下，其他非穿戴者可以直接看到穿戴者的面部图像，则可以获知穿戴设备已开启***。
在目标提示信息包括虚拟对象的部分面部图像或完整面部图像的情况下，虚拟对象可以是三维虚拟人物、二维虚拟人物、三维虚拟动物或二维虚拟动物，在此不作具体限定。
因此，虚拟对象的部分面部图像或完整面部图像可以是二维面部图像或三维面部图像。例如：虚拟对象可以是动漫人物、虚拟数字人或虚构的角色等。
需要说明的是，虚拟对象的部分面部图像或完整面部图像可以是虚构出来的人物或动物的面部图像，也可以是基于上述实施例中的面部特征数据生成的面部图像，即根据穿戴者的面部特征数据，可以转换成虚拟对象的部分面部图像或完整面部图像，该虚拟对象的面部特征数据与穿戴者的面部特征数据相对应。
虚拟对象的部分面部图像为包含虚拟对象的至少一个脸部部位的面部图像，完整面部图像为包含虚拟对象的所有脸部部位的面部图像。
“透视”本意为“视线穿透”，虚拟对象的部分面部图像可以至少包括眼部，便于非穿戴者更容易理解到目标提示信息的含义。
如图7所示，在穿戴设备的***已开启的情况下，在穿戴设备的外侧显示屏显示二维虚拟人物的眼部图像，该二维虚拟人物为虚构的人物形象。
在一些实施例中，在目标提示信息包括穿戴设备的穿戴者的部分人脸图像的情况下，部分人脸图像中的人脸特征点与穿戴者的目标人脸区域中的人脸特征点相匹配；
部分人脸图像中的人脸外轮廓与穿戴者的目标人脸区域的人脸外轮廓相同；
其中，目标人脸区域为穿戴者的人脸被穿戴设备的外侧显示屏遮挡的人脸区域。
在实际使用穿戴设备的过程中，穿戴者会将穿戴设备戴在头上，穿戴设备的外侧显示屏会对穿戴者的面部进行部分遮挡。
为了提高非穿戴者的视觉体验，可以根据穿戴者人脸被穿戴设备的外侧显示屏遮挡的人脸区域，在外侧显示屏展示穿戴者的部分人脸图像。
在本申请实施例中，部分人脸图像为目标人脸区域对应的人脸图像，目标人脸区域即为被穿戴者的人脸被穿戴设备的外侧显示屏遮挡的人脸区域。
在实际执行中，穿戴者的部分人脸图像满足以下条件：
部分人脸图像中的人脸特征点与穿戴者的目标人脸区域中的人脸特征点相匹配；且部分人脸图像中的人脸外轮廓与穿戴者的目标人脸区域的人脸外轮廓相同。
可以理解的是，人脸特征点的匹配说明了部分人脸图像所包含的人脸部位和目标 人脸区域中的人脸部位以及部位所在位置相对应。在此基础上，部分人脸图像中的人脸外轮廓与穿戴者的目标人脸区域的人脸外轮廓也相同，此时外侧显示屏呈现的穿戴者的部分人脸图像可以与目标人脸区域对应的人脸图像可以完全一致。
从非穿戴者的视角，穿戴者的部分人脸图像与未被遮挡的人脸区域的结合，可以给非穿戴者提供完整人脸的视觉体验。
如图8左图所示，目标人脸区域包括的人脸部位有眼睛、鼻子和耳朵，如图8右图所示，外侧显示屏显示的部分人脸图像中的人脸部位有眼睛、鼻子和耳朵，即有部分人脸图像中的人脸特征点与穿戴者的目标人脸区域中的人脸特征点相匹配。并且目标人脸区域的人脸外轮廓与部分人脸图像中的人脸外轮廓相同。图8右图中穿戴者的部分人脸图像与未被遮挡的人脸区域相结合可以看到一张流畅且完整的人脸。
根据本申请实施例提供的信息提示方法，通过匹配部分人脸图像和目标人脸区域的外轮廓和人脸特征点，可以提高目标提示信息显示效果，使得非穿戴者看到的人脸更为逼真。
在目标提示信息包括场景图像的情况下，场景图像为穿戴设备所处的现实场景的二维场景图像或三维场景图像。现实场景即为穿戴设备所处的真实环境。
在穿戴设备已开启***的情况下，可以根据现实场景生成二维场景图像或三维场景图像。
在穿戴设备的外侧显示屏显示场景图像的情况下，非穿戴者可以直接看到与穿戴设备的穿戴者视角相同的真实环境。场景图像可以包括真实环境中的所有人或物。穿戴者通过该场景图像可以获知穿戴设备已开启***。
如图9所示，图9展示了穿戴者所看到穿戴设备所处现实场景。如图10所示，在穿戴设备的外侧显示屏显示了该现实场景下的二维场景图像。
根据本申请实施例提供的信息提示方法，通过在外侧显示屏显示不同的目标显示信息，可以让非穿戴者简单明了地获得***已开启的提示，在保证提示效果的情况下，还可以保证一定的视觉体验。
在一些实施例中，在目标提示信息包括穿戴设备的穿戴者的面部图像的情况下，在穿戴设备的外侧显示屏，显示目标提示信息，包括：
在检测到穿戴者的表情动作信息发生变化的情况下，更新面部图像。
需要说明的是，为了提高目标显示信息的视觉显示效果，目标提示信息的信息显示方式可以采用静态显示或动态显示。
静态显示指的是目标提示信息显示的内容在***开启状态保持不变的情况下，静态显示的内容也保持不变。例如：在穿戴设备开启***时，生成穿戴者的面部图像，并显示在穿戴设备的外侧显示屏，该图像内容可以保持不变。
在本申请实施例中，动态显示指的是基于穿戴者的面部特征数据生成的穿戴者的面部图像或虚拟对象的面部图像，都可以根据人脸的表情动作信息变化而对显示的面 部图像进行实时动态更新，从而可以实时显示穿戴者当前的表情动作信息，便于周围的其他非穿戴者能知晓穿戴者当前的真实情绪状态，提高了目标提示信息的真实感。
在一些实施例中，动态显示还可以是在***开启的情况下，给文本提示信息设置为闪烁效果或滚动显示效果等动画效果，或者是在显示二维虚拟人物的面部图像时，给眼部图像设置自然眨动效果或给嘴部图像设置开合效果等，在此不作具体限定。上述动态效果的处理均可以通过GPU完成。
在实际执行中，在检测到穿戴者的表情动作信息发生变化的情况下，可以实时生成不同的面部图像，从而可以获得连续采集的多帧静态显示的面部图像。然后可以在外侧显示屏播放连续的多帧面部图像，即可看到表情动作信息动态变化的面部图像。
根据本申请实施例提供的信息提示方法，通过在检测到穿戴者的表情动作信息发生变化的情况下，在外侧显示屏动态更新面部图像，从而使得面部图像可以根据人脸表情变化而实时更新，使得目标显示信息贴近真实人脸表情，显示效果更加逼真。
在一些实施例中，在检测到穿戴者的表情动作信息发生变化的情况下，更新面部图像之前，信息提示方法还包括：
采集穿戴者的人脸特征点；
在检测到穿戴者的至少部分人脸特征点的位置发生变化的情况下，确定穿戴者的表情动作信息发生变化。
在实际执行中，穿戴设备可以通过脸部追踪器可以实时采集穿戴者的人脸特征点，实现对穿戴者的人脸特征点进行追踪。
可以理解的是，穿戴设备在实时生成的连续多帧面部图像中，可以确定每一帧图像中的人脸特征点的位置，比较不同帧的面部图像中的同一特征点的位置，即可确定人脸特征点的位置是否发生变化。
在检测到穿戴者的至少部分人脸特征点的位置发生变化的情况下，说明穿戴者人脸中的至少一个部位的动作形态在变化，从而可以确定穿戴者的表情动作信息发生变化。例如：在检测到穿戴者的眼部特征点的位置发生变化，即可确定穿戴者的表情动作信息变化，在外侧显示屏显示的面部图像展现的效果为穿戴者由向左看变成了向右看。
根据本申请实施例提供的信息提示方法，通过采集穿戴者的人脸特征点检测，可以实时检测穿戴者的表情动作信息是否发生变化，并在表情动作发生变化的情况下实时更新面部图像。
在一些实施例中，在目标提示信息包括场景图像的情况下，在穿戴设备的外侧显示屏，显示目标提示信息之前，信息提示方法还包括：
采集穿戴设备所处现实场景的场景信息；
基于场景信息，生成现实场景的二维场景图像或三维场景图像；
在穿戴设备的外侧显示屏，显示目标提示信息，包括：
在穿戴设备的外侧显示屏，显示二维场景图像或三维场景图像。
在实际执行中，可以通过穿戴设备的摄像头直接拍摄穿戴设备所处现实场景的场景信息，生成二维场景图像。
穿戴者可以通过内侧显示屏看到对现实场景的拍摄预览界面，则穿戴者可以直接看到现实场景的场景信息，非穿戴者可以通过外侧显示屏看到二维场景图像对应拍摄预览图像，从而非穿戴者可以知道该穿戴设备的***已开启。
可以理解的是，穿戴者可以在现实场景中任意走动，穿戴设备采集的所处现实场景的场景信息在动态变化，因此，可以对现实场景进行连续拍摄，生成连续的二维场景图像，并在外侧显示屏连续显示，及时更新穿戴者当前视角下的二维场景图像。
在实际执行中，穿戴者可以在不同位置以及使用不同角度拍摄穿戴设备所处现实场景的二维场景图像，获得现实场景的二维场景图像序列。
GPU可以根据对二维场景图像序列进行特征点提取和特征点匹配，并基于运动恢复结构算法(Structure From Motion，SFM)或由轮廓重构物体三维模型算法(Shape From Silbouette，SFS)进行场景图像的三维重建，从而得到现实场景的三维场景图像，并且可以在外侧显示屏显示三维场景图像。
如图9所示，穿戴者开启穿戴设备的***，并拍摄正对面的现实场景，从而获取穿戴设备所处真实环境的场景信息，并把场景信息传给GPU。GPU根据真实环境信息进行三维图像重建，生成三维场景图像。
根据本申请实施例提供的信息提示方法，通过采集穿戴设备所处现实场景的场景信息，生成现实场景的二维场景图像或三维场景图像，并在穿戴设备的外侧显示屏显示二维场景图像或三维场景图像，来提示该穿戴设备的***已开启，使得非穿戴者及时得到该目标提示信息，从而便于非穿戴者保护隐私。
