图3是本申请一个示例性实施例提供的一种显示内容的方法的流程图。该显示内容的方法可以应用在图1所示的头戴式显示设备中。在图3中，显示内容的方法包括：
步骤310，在头戴式显示设备的显示区域显示第一父级界面。
在本申请实施例中，头戴式显示设备能够在全部显示区域中显示第一父级界面，或者在部分显示区域中显示第一父级界面。
在一种可能的方式中，头戴式显示设备包括左侧镜片内侧和右侧镜片内侧。头戴式显示设备既可以以VR的形式显示，也即两个镜片内侧均显示第一父级界面，在用户的视觉中，感觉能够以立体视觉观看到第一父级界面。在该场景中，头戴式显示设备在全部显示区域中显示第一父级界面。
在另一种可能的方式中，头戴式显示设备包括左侧镜片内侧和右侧镜片内侧。头戴式显示设备可以仅在其中一侧的镜片内侧显示第一父级界面。在该显示方式中，头戴式显示设备在部分显示区域中显示第一父级界面。
在又一种可能的方式中，头戴式显示设备包括左侧镜片内侧或右侧镜片内侧。在该场景中，头戴式显示设备将在全部显示区域中显示第一父级界面。
需要说明的是，头戴式显示设备可以在满足预定条件下，在显示区域显示第一父级界面。预定条件可以是头戴式显示设备检测到被用户佩戴。或者，预定条件也可以是头戴式显示设备接收到亮屏操作。其中，亮屏操作可以是触控操作、实体按键操作、敲击操作或眼动操作中的一种。
需要说明的是，头戴式显示设备中可以设置触摸感知区域。触控操作可以是长按操作、滑动操作、轻压操作、重按操作、小面积按压或大面积按压中的一种。需要说明的是，长按操作是指按压触摸感知区域的时间长度超过第一时长，短按操作是指按压触摸感知区域的时间长度等于或者等于第一时长。其中，第一时长可以是1秒、1.5秒或者2秒的时长场景，设计者可以根据实际需求进行设计，不对第一时长具体的数值进行限定。滑动操作是在触摸感知区域内的滑动操作。轻压操作是按压压力值小于或等于压力阈值的操作，重按操作是大于压力阈值的操作。其中，压力阈值可以是设计者预先设定的常数值。小面积按压操作是产生按压信号的面积小于或者等于面积阈值的操作。大面积按压操作是产生按压信号的面积大于面积阈值的操作。其中，面积阈值可以是0.5平方厘米、0.8平方厘米或者1平方厘米等数值。
示意性的，实体按键操作可以是按压头戴式显示设备中的某一按键或者多个按键，本申请实施例对此不作限定。敲击操作是通过敲击头戴式显示设备的操作。眼动操作包括眼球转动操作，头戴式显示设备中设置有拍摄眼球运动的摄像头，能够识别眼球朝向某一方向的转动，当眼球转向某一方向且停留时 长超过第二时长时，确认接收到对应的眼动操作。例如，当用户的眼球转向左侧且停留时长超过2秒时，头戴式显示设备中生成左转眼动操作对应的指令。其中，第二时长可以是0.8秒、1秒、1.2秒或者1.5秒，本申请不对第二时长的具体的数值进行限定。
需要说明的是，头戴式显示设备可以通过内置的加速度传感器检测，当头戴式显示设备被敲击时，内置的加速度传感器将会在一个较短的时间片中产生较大的加速度。基于该原理，头戴式显示设备即可通过加速度传感器判断出敲击操作。
示意性的，头戴式显示设备可以在显示区域中全屏显示第一父级界面。请参见图4，图4是基于图3所示实施例提供的一种第一父级界面的示意图。在图4中，右侧镜片内侧的显示区域将全屏显示第一父级界面4a。
请参见图5，图5是基于图3所示实施例提供的一种两级界面的平面铺展示意图。在图5中，第一父级界面4a的上下两侧分别显示第一子级界面4a1和第二子级界面4a2。需要说明的是，本申请中以子级界面一共是两个为例进行说明，子级界面的数量可以根据需要自由调整。在子级界面的排列方式中，当子级界面一共是两个时，该两个子级界面可以均分布在第一父级界面4a的上侧成为第一子级界面4a1，也可以均分布在第一父级界面4a的下侧成为第二子级界面4a2，本申请实施例对此不作限定。
在图5中，第二父级界面4b和第三父级界面4c分布在第一父级界面4a的左右两侧。需要说明的是，父级界面的数量同样能够按照需要调整，本申请不对其进行限定。
在图5中，第一父级界面4a所在的位置表示头戴式显示设备的显示区域。本申请通过最扁平化的信息架构进行内容展示，减少多层级结构对用户带来的认知负担，避免用户在操作过程中因忘记层级关系而难以找到需要显示的内容。
类似于图5所示的两级界面的平面铺展示意图。本申请所示的方案还可以通过图6至图8所示的界面平面关系设置。其中，图6至图8中所涉及的界面标识和图5相同，此处不再赘述。
请参见图9，图9是基于图3所示实施例提供的一种两级界面的空间分布示意图。在图9中，父级界面沿水平方向的环形轨道6A环绕用户分布，子级界面沿竖直方向的环形轨道6B环绕用户分布。其中，父级界面以第一父级界面4a、第二父级界面4b和第三父级界面4c示意。子级界面以第一子级界面4a1和第二子级界面4a2示意。上述界面围绕用户的眼睛600显示。
在本申请中，空间环状结构有利于信息呈现的包裹感，为今后头戴式显示设备的交互界面设计留下了拓展空间，提高了头戴式显示设备的交互界面的扩展性。
请参见图10，图10是本申请实施例提供的一种界面的空间展开示意图。其中，第一父级界面4a是一个健身应用的主界面。第一子级界面4a1是健身界面中的仰卧起坐子级界面。第二子级界面4a2是健身界面中的身体参数子级界面。第一个第三父级界面4c1是地图应用的界面，第二个第三父级界面4c2是音乐应用的界面。第一个第二父级界面4b1是消息应用的界面，第二个第二父级界面4b2是翻译应用的界面。
需要说明的是，各个界面之间切换的动画效果可以包括推出、景深、推压、方盒、旋转、翻转、翻页或风车等动画效果，本申请实施例对此不作限定。
请参见图11，图11是本申请实施例提供的一种界面的水平排列示意图。其中，第一父级界面4a是当前显示的界面，第二父级界面4b、第一个第三父级界面4c1和第二个第三父级界面4c2均是当前不显示的界面。
需要说明的是，本申请在执行完成步骤310后，将根据所接收到的滑动操作来选择执行步骤320或者执行步骤330。当头戴式显示设备接收到第一滑动操作后，将执行步骤320；当头戴式显示设备接收到第二滑动操作后，将执行步骤330。
步骤320，响应于第一滑动操作，基于第一滑动操作所指示的第一滑动方向，将第一父级界面滑出显示区域，以及将第二父级界面滑入显示区域，第二父级界面和第一父级界面的级别相同。
在本申请实施例中，头戴式显示设备能够接收第一滑动操作。在本申请中，头戴式显示设备中可以在用户容易触控的位置设置触摸感知区域。其中，该触摸感知区域中设置有触摸传感器，能够接收用户的触控操作。可选的，触摸感知区域感知触摸操作的原理可以是电容式触控、电阻式触控、红外式触控或光学触控，本申请实施例对此不作限定。
其中，用户在触摸感知区域中进行沿第一滑动方向滑动手指的过程是第一滑动操作。因此，头戴式显示设备能够基于第一滑动操作确定出对应的第一滑动方向。需要说明的是，基于第一滑动方向将第一父级界面滑出显示区域时，需要将第一滑动方向映射至显示区域。进而，按照第一滑动方向映射到显示区域中的方向，将第一父级界面滑出显示区域，并将第二父级界面滑入显示区域。其中，第一父级界面和第二父级界面同属父级界面。在一种可能的实现方式中，第一父级界面是第一应用的主界面，第二父级界面是第二应用的主界面，本申请实施例对此不作限定。
其中，第一滑动操作既可以是在镜腿上的滑动操作，也可以是在与头戴式显示设备配合使用的手柄上的滑动操作或者是拨动该手柄上的拨杆的操作。
例如，在一种可能的控制方式中，若头戴式显示设备的外形是眼镜，则第一滑动操作可以是用户沿着镜腿从后向前滑动。在此情况下，显示区域中的第一父级界面从左侧滑出，第二父级界面从显示区域的右侧进入。
请参见图12，图12是基于图3所示实施例提供的一种显示内容的示意图。在图12中，头戴式显示设备100在右侧镜片的内侧作为显示区域，用来显示第一父级界面710。此时，若用户在右侧镜腿从后向前沿镜腿滑动，则智能眼镜视为自身接收到第一滑动操作。可选地，在接收用户的第一滑动操作的过程中，显示区域中可以播放第一父级界面710从显示区域左侧边缘滑出且第二父级界面720从显示区域右侧边缘滑入的过程。可选地，头戴式显示设备可以根据用户在镜腿上的滑动距离来确定是否完全显示第二父级界面720。例如，预先设置完成一个父级界面切换的距离是1厘米，则当用户在右侧镜腿上沿第一滑动方向滑动了1厘米时，头戴式显示设备将第一父级界面710完全滑出显示区域，并在显示区域中显示第二父级界面720。当用户继续沿第一滑动方向滑动时，头戴式显示设备将第二父级界面720从显示区域的左侧边缘滑出，并将第二父级界面720右侧的第三父级界面继续滑入。
可选地，在图12所示的场景中，当用户在左侧镜腿从前向后沿镜腿滑动，也能够实现将第一父级界面710从显示区域左侧边缘滑出且第二父级界面720从显示区域右侧边缘滑入。
步骤330，响应于第二滑动操作，基于第二滑动操作所指示的第二滑动方向，将第一父级界面滑出显示区域，以及将第一子级界面滑入显示区域，第二滑动方向垂直于第一滑动方向，第一子级界面是第一父级界面的子界面。
在本申请实施例中，当头戴式显示设备在显示区域中显示的如第一父级界面的界面时，头戴式显示设备能够接收第二滑动操作，并响应第二滑动操作，基于第二滑动操作的第二滑动方向，将第一父级界面滑出显示区域，并将第一自寄界面滑入显示区域。其中，第二滑动方向垂直于第一滑动方向。
请参考图13，图13是基于图3所示实施例提供的另一种显示内容的示意图。在图13中，头戴式显示设备100在右侧镜片的内侧作为显示区域，用来显示第一父级界面710。此时，若用户在右侧镜腿从下侧边缘朝上侧边缘滑动，则智能眼镜视为自身接收到第二滑动操作。可选地，在接收用户的第二滑动操作的过程中，显示区域中可以播放第一父级界面710从显示区域上侧边缘滑出且第一子级界面711从显示区域下侧边缘滑入的过程。可选的，头戴式显示设备可以根据用户在镜腿上的滑动距离来确定是否完全显示第一子级界面711。例如，预先设置完成一个子级界面切换的距离是0.5厘米，则当用户在右侧镜腿上从下向上(沿第二滑动方向)方向滑动了0.5厘米时，头戴式显示设备将第一父级界面710完全滑出显示区域，并在显示区域中显示第一子级界面711。当用户继续沿第二滑动方向滑动时，头戴式显示设备将第一子级界面711从显示区域的上侧边缘滑出，并将第二子级界面从显示区域的下侧变化滑入。
需要说明的是，上述第一滑动方向和第二滑动方向垂直。在头戴式显示设备上能够被操作的空间有限的情况下，能够便于用户明确分辨自身作出的是第一滑动操作还是第二滑动操作。
综上所述，本申请在头戴式显示设备的显示区域中先显示第一父级界面，在第一滑动操作的作用下，沿第一滑动方向将当前显示的第一父级界面替换为第二父级界面，或者，在第二滑动操作的作用下，沿第二滑动方向将当前显示的第一父级界面替换为第一子级界面。其中，上述两个滑动方向互相垂直，且第二父级界面和第一父级界面的级别相同，第一子级界面是第一父级界面的子界面。由于本申请能够通过互相垂直的两个滑动方向来分别实现不同应用程序的切换，以及，应用内不同的子界面之间的切换。因此，本申请能够减少头戴式显示设备中的交互界面的层级，令交互界面扁平化，提高切换交互界面的效率。
基于上一个实施例所公开的方案，终端还能够将用于切换的各个界面设计成环形，请参考如下实施例。
请参见图14，图14是本申请另一个示例性实施例提供的一种显示内容的方法流程图。该显示内容方法可以应用在上述图1所示的头戴式显示设备中。在图14中，该显示内容的方法包括：
步骤910，在头戴式显示设备的显示区域显示第一父级界面。
在本申请中，步骤910的执行过程和步骤210的执行过程相同，此处不再赘述。
步骤921，在第一父级界面是n个父级界面中排序在第i位置的父级界面的情况下，响应于第一滑动操作，基于第一滑动操作所指示的第一滑动方向，将第i位置的父级界面滑出显示区域，以及将第i+1位置的父级界面滑入显示区域。
其中，i为小于n的整数。
在本申请中，无论当前显示的父级界面是n个父级界面中的哪一个位置的父级界面。头戴式显示设备均可以按照既定规则，来响应第一滑动操作来切换显示区域中的父级界面。比如，当第一父级界面是总数为n的父级界面中的第i位置，则响应第一滑动操作，将第一父级界面滑出显示界面并将位置是第i+1的父级界面滑入显示区域。需要说明的是，i的取值不能等于n，i是小于n的正整数。
若第一父级界面是n个父级界面中的最后一个位置(即第n位置)的父级界面，头戴式显示设备将执行步骤922以实现父级界面之间的切换。
步骤922，在第一父级界面是n个父级界面中排序在第n位置的父级界面的情况下，响应于第一滑动操作，基于第一滑动操作所指示的第一滑动方向，将第n位置的父级界面滑出显示区域，以及将第1位置的父级界面滑入显示区域。
在本申请实施例中，n个父级界面的排序方向和第一滑动方向相同。
在本申请实施例中，头戴式显示设备能够在第一父级界面是n个父级界面中的第n位置的父级界面时，响应于第一滑动操作，重新将第1位置的父级界面滑入显示区域，并将第n位置的父级界面滑出显示区域。
例如，当头戴式显示设备并列显示4个父级界面，例如，4个父级界面对应的应用名称如表一所示。
表一
父级界面 健身主页 音乐主页 词典主页 社交主页
应用名称 健身应用 音乐应用 词典应用 社交应用
位置 第1位置 第2位置 第3位置 第4位置
需要说明的是，第一父级页面是健身主页、音乐主页或词典主页时，头戴式显示设备将在切换显示至后一位置的父级界面。例如，在第一父级页面是健身主页时，头戴式显示设备响应第一滑动操作，将显示区域切换显示为音乐主页。在第一父级页面是音乐主页时，头戴式显示设备响应第一滑动操作，将显示区域切换显示为词典主页。在第一父级页面是词典主页时，头戴式显示设备响应第一滑动操作，将显示区域切换显示为社交主页。
在本申请提供的另一种可能的方式中，若第一父级页面是第4位置的社交主页，头戴式显示设备响应第一滑动操作，将显示区域切换显示为第1位置的健身主页。由此可见，头戴式显示设备中显示的n个父级界面能够实现首尾相接的环状切换。
在一种落地的实现方式中，终端能够通过执行下列步骤(a)，来实现步骤921或步骤922所示的滑出一个父级界面并滑入一个父级界面的效果。
步骤(a)，响应于第三滑动操作，基于第三滑动操作所指示的第三滑动方向，将第一父级界面滑出显示区域，以及将第三父级界面滑入显示区域。
其中，第三父级界面和第一父级界面的级别相同。第三滑动方向和第一滑动方向互为反方向。
需要说明的是，第三滑动操作和第一滑动操作所作用的触摸感知区域是同一个触摸感知区域。例如，当头戴式显示设备的左侧镜腿中包括第一触摸感知区域，同时右侧镜腿中包括第二触摸感知区域。则本申请中所示的第一滑动操作和第三滑动操作均是作用于第一触摸感知区域的操作，或者，本申请中所示的第一滑动操作和第三滑动操作均是作用于第二触摸感知区域的操作。
当头戴式显示设备响应于第三滑动操作，能够基于第一滑动方向的反方向(第三滑动方向)，将第一父级界面滑出显示区域，并将第三父级界面滑入显示区域。
步骤931，在第一父级界面是n个父级界面中排序在第1位置的父级界面的情况下，响应于第三滑动操作所指示的第三滑动方向，将第1位置的父级界面滑出显示区域，以及将第n位置的父级界面滑入显示区域。
其中，第三滑动方向和第一滑动方向互为反方向。
在该场景中，头戴式显示设备在第三滑动操作下控制第一父级界面滑出的方向，和头戴式显示设备在第一滑动操作下控制第一父级界面滑出的方向相反。
需要说明的是，当第一父级界面在第1位置时，该第一父级界面滑出后，n个父级界面中的第n位置的父级界面将滑入显示区域。
步骤932，在第一父级界面是n个父级界面中排序在第i位置的父级界面的情况下，响应于第三滑动操作，基于第三滑动操作所指示的第三滑动方向，将第i位置的父级界面滑出显示区域，以及将第i-1位置的父级界面滑入显示区域，i为大于1的整数。
在本例中，若第一父级界面是处理第1位置的父级界面时，该第i位置的父级界面滑出时，显示区域中将滑入第i-1位置的父级界面。
以表二所示各个父级界面、应用名称和位置的对应关系为例。

需要说明的是，第一父级页面是音乐主页、词典主页和社交主页时，头戴式显示设备将在切换显示至前一位置的父级界面。例如，在第一父级页面是音乐主页时，头戴式显示设备响应第三滑动操作，将显示区域切换显示为健身主页。在第一父级页面是词典主页时，头戴式显示设备响应第三滑动操作，将显示区域切换显示为音乐主页。在第一父级页面是社交主页时，头戴式显示设备响应第一滑动操作，将显示区域切换显示为词典主页。
在本申请提供的另一种可能的方式中，若第一父级页面是第1位置的健身主页，头戴式显示设备响应第三滑动操作，将显示区域切换显示为第4位置的社交主页。由此可见，头戴式显示设备中显示的n个父级界面能够实现首尾相接的环状切换。
步骤941，在当前显示的界面是第1位置的第一父级界面的情况下，响应于第二滑动操作，基于第二滑动操作所指示的第二滑动方向，将第1位置的第一父级界面滑出显示区域，以及将第2位置的第一子级界面滑入显示区域。
其中，第一父级界面和m个子级界面的排序方向和第二滑动方向相同。
其中，第一父级界面和m-1个子级界面按照第二滑动方向排序在第1位置至第m位置，m为正整数。
需要说明的是，第二滑动操作用于切换第一父级界面和其所从属的多个子级界面。在本申请实施例中，例如第一父级界面是健身应用，则其所从属的多个子级界面可以包括仰卧起坐子界面和生理参数子界面。头戴式显示设备根据第二滑动方向将健身主页面滑出显示区域，并将第2位置的第一子级界面滑入显示区域。若生理参数子界面是第一子级界面，则头戴式显示设备将生理参数子界面滑入显示区域。
步骤942，在第一子级界面排序在第j位置的情况下，响应于第二滑动操作，基于第二滑动操作所指示的第二滑动方向，将第j位置的第一子级界面滑出显示区域，以及将第j+1位置的子级界面滑入显示区域。
其中，j为小于m且大于1的整数。
在本例中，头戴式显示设备可以在第一子级界面排序的第j位置不是第m位置时，在第二滑动操作的作用下，将第j位置的第一子级界面滑出显示区域，并将第j+1位置的子级界面滑入。
步骤943，在第一子级界面排序在第m位置的情况下，响应于第二滑动操作，基于第二滑动操作所指示的第二滑动方向，将第m位置的第一子级界面滑出显示区域，以及将第1位置的第一父级界面滑入显示区域。
在一种特殊的场景下，当第一子级界面排序在第m位置时，头戴式显示设备在第二滑动操作的作用下，将第m位置的第一子级界面滑出显示区域，将第1位置的第一父级界面滑入。
步骤951，响应于第四滑动操作，基于第四滑动操作所指示的第四滑动方向，将第1位置的第一父级界面滑出显示区域，以及将第m位置的第二子级界面滑入显示区域。
其中，第四滑动方向和第二滑动方向互为反方向。
在本例中，当头戴式显示设备受到与第二滑动方向互为反方向的第四滑动方向的作用时，头戴式显示设备受到第四滑动操作的作用，将采用与受到第二滑动操作时相反的滑出方向滑出界面。
步骤952，在第二子级界面排序在第j位置的情况下，响应于第四滑动操作，基于第四滑动操作所指示的第二滑动方向，将第j位置的第二子级界面滑出显示区域，以及将第j-1位置的子级界面滑入显示区域。
其中，j为小于m且大于1的整数。
步骤953，在第二子级界面排序在第2位置的情况下，响应于第四滑动操作，基于第四滑动操作所指示的第二滑动方向，将第2位置的第二子级界面滑出显示区域，以及将第1位置的第一父级界面滑入显示区域。
综上所述，本实施例能够根据用户在头戴式显示设备上的滑动操作的不同，而采用不同的滑出方向滑出当前显示的界面，并按照滑动操作的方向滑入新的界面。由于本申请提供了两个互相垂直的方向，且其中一个方向用于同一级别的父级界面之间的切换，另一个方向用于将一个父级界面和其从属的多个子级界面之间的切换。并且通过环形排列的方式，提供了用户快速切换至自身需要的界面的效率，避免了用户当前在靠前位置的界面，需要从前到后的多次操作才能够切换至所需的界面的繁琐步骤。
可选的，由于本申请为头戴式显示设备提供了十字型界面的切换结构，因此，本申请能够令各个用户所需的界面并平滑，利于用户的快速了解各个界面切换的逻辑。比如用户当前处于A应用的父级界 面，则用户了解该界面既可以在第一滑动方向或者第一滑动方向的反方向(即第三滑动方向)的滑动操作下，切换至其它父级界面，并且能够通过与第一滑动方向垂直的第二滑动方向的滑动操作下，切换至A应用中的各个子级界面，降低了用户熟悉该操作的学习成本。
基于上述实施例所示的方法，本申请实施例还提供一种显示内容的方法，能够在父级界面较多的情况下分组显示，并且还能够显示每个父级界面对应的图标，便于用户确定自身需要查找的父级界面。请参考如下实施例。
请参考图15，图15是本申请提供的一种显示内容的方法的流程图，可以应用在图1所示的头戴式显示设备中。在图15中，所述方法包括：
步骤1001，在头戴式显示设备的显示区域显示第一父级界面。
在本例中，步骤1001的执行过程可以分别参照步骤210的执行过程，此处不再赘述。
步骤1002，响应于界面缩小操作，在显示区域中将第一父级界面从全屏显示状态转变为缩小显示状态，并在显示区域中缩小后出现的空白区域中显示n个父级界面各自的应用图标，且第一父级界面的应用图标突出显示。
请参见图16，图16是基于图15所示实施例提供的一种界面缩小的示意图。在图16中，显示区域11A在头戴式显示设备接收界面缩小操作之前全屏显示第一父级界面1111。在头戴式显示设备接收到界面缩小操作之后，显示区域11A中显示缩小的第一父级界面1111，并在第一父级界面1111缩小后产生的空白区域中显示n个父级界面各自对应的应用图标。在图16中，以n是4为例。显示区域11A将与缩小后的第一父级界面1111并列显示4个应用图标，分别是健身应用图标1121、社交应用图标1122、音乐应用图标1123和翻译应用1124。
其中，由于第一父级界面1111是健身应用的父级界面，因此，健身应用图标1121突出显示。
请参考图17，图17是是基于图15所示实施例提供的一种界面缩小和放大的过程示意图。在图17中，头戴式显示设备先在显示区域全屏显示第一父级界面710，然后在接收到界面缩小操作时，缩小第一父级界面710并显示4个父级界面各自的应用图标。其中，第一父级界面710的应用图标突出显示。在图17中，该突出显示的方式是外围加粗框线显示。在缩小状态下，用户依然还能够切换显示区域中显示的界面，该界面既可以是父级界面，也可以是子级界面。在图17中，该界面以父级界面为例进行介绍。当第二父级界面在显示区域中处于缩小显示状态，且第二父级界面的应用图标突出显示时，头戴式显示设备能响应于界面放大操作，在显示区域中将第二父级界面从缩小显示状态切换为全屏显示状态，如图17中全屏显示的是第二父级界面720。
步骤1003，响应于镜腿上感知到水平方向滑动，确认接收到第一滑动操作。
其中，头戴式显示设备包括设置有触摸感知区域的镜腿。
步骤1004，响应于第一滑动操作，基于第一滑动操作所指示的第一滑动方向，将第一父级界面滑出显示区域，以及将第二父级界面滑入显示区域。
其中，第二父级界面和第一父级界面的级别相同。
在本例中，步骤1004的执行过程可以分别参照步骤220的执行过程，此处不再赘述。
步骤1005，在第二父级界面在显示区域中处于缩小显示状态，且第二父级界面的应用图标突出显示的情况下，响应于界面放大操作，在显示区域中将第二父级界面从缩小显示状态切换为全屏显示状态，并在显示区域中取消显示n个父级界面各自的应用图标。
需要说明的是，第二父级界面可以与第一父级界面是同一个父级界面；第二父级界面也可以与第一父级界面是不同的父级界面。
在本例中，界面缩小操作可以是触控操作、敲击操作或者实体按钮操作中的至少一种，本申请实施例对此不作限定。
步骤1006，响应于镜腿上感知到竖直方向滑动，确认接收到第二滑动操作。
步骤1007，响应于第二滑动操作，基于第二滑动操作所指示的第二滑动方向，将第一父级界面滑出显示区域，以及将第一子级界面滑入显示区域，第二滑动方向垂直于第一滑动方向。
其中，第一子级界面是第一父级界面的子界面。
在本例中，步骤1007的执行过程可以分别参照步骤230的执行过程，此处不再赘述。
可选地，为了提高用户使用头戴式显示设备切换父级界面的效率。头戴式显示设备中可以设置并列显示的父级界面数量的上限，也即对n的数值进行限定。例如，将n的上限设为5。若头戴式显示设备中运行的应用多于5个时，将其编入其它组。
举例而言，若头戴式显示设备中运行有n个父级界面，且一组父级界面的上限是q个，则头戴式显示设备中运行[n/q]+1组父级界面。需要说明是，[n/q]表示对数值n/q取整。比如，n/q的数值2.2，则 [n/q]的值是2。
比如，头戴式显示设备中运行有9个父级界面，且一组父级界面的上限是5个，则头戴式显示设备中运行2组父级界面。其中，第一组包括第1父级界面至第5父级界面；第二组包括第6父级界面至第9父级界面。
当头戴式显示设备当前显示的是第一组父级界面时，且用户想要查看第二组中的父级界面，则需要用户将第一组父级界面切换至第二组父级界面。
本申请提供以下切换方式，在应用该切换方式的头戴式显示设备中包括加速度传感器。头戴式显示设备通过加速度传感器监测头戴式显示设备的运动事件；在头戴式显示设备处于亮屏显示的情况下，响应于头戴式显示设备产生单次前滚运动事件，头戴式显示设备可以执行分支一或者执行分支二。其中，单次前滚运动事件可以是头戴式显示设备在指定时长内前滚角度超过指定角度后恢复至初始姿态的事件。或者，单次前滚运动事件还可以是头戴式显示设备向前滚动的速度超过阈值时触发的事件。
分支一：将n个父级界面中的q个第四父级界面替换为n-q个第五父级界面。其中，n小于或者等于2q。
分支二：将n个父级界面中的q个第四父级界面替换为q个第五父级界面。其中，n大于2q。
在实际操作中，用户可将头戴式显示设备摘下并快速前倾一下，或者佩戴该头戴式显示设备时向前快速点头一下来完成单次前滚运动事件。
综上所述，本实施例提供的显示内容的方法，能够在用户还不熟悉父级界面切换顺序或者父级界面较多时，通过显示父级界面对应的应用图标来提示用户的移动至自己所需要的父级界面或者子级界面，提高了用户切换头戴式显示设备中的界面的效率。
