Description

一种基于折叠屏的交互方法及设备
本申请要求于2019年7月17日提交国家知识产权局、申请号为201910646369.2、申请名称为“一种基于折叠屏的交互方法及设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及电子技术领域，尤其涉及一种基于折叠屏的交互方法及设备。
背景技术
折叠屏设备通常具有较大的屏幕，可以为用户提供更好的视觉观看体验。现有技术中，用户通常需要在大折叠屏的特定位置执行特定的手势，从而与折叠屏进行交互，触发折叠屏设备执行特定的操作或特定的功能。现有折叠屏交互方式使得用户体验较差。
尤其在单手握持折叠屏设备的场景下，由于特定位置可能难以触及，特定位置和特定手势难以准确记忆，特定手势难以操作，因而该种交互方式较为复杂，不便实施，且成功率较低，用户体验较差。
例如，在单手握持的场景下，参见图1A，用户由右下角向折叠屏中部滑动时，可以开启右手单手模式。若用户由左下角向折叠屏中部滑动，则可以开启左手单手模式。再例如，参见图1B，用户由折叠屏内的导航键01开始，在导航区域内向右滑动时，可以开启右手单手模式。若用户由折叠屏内的导航键开始，在导航区域内向左滑动，则可以开启左手单手模式。
图1A或图1B所示的开启单手模式的交互方式，需要准确记忆操作位置和操作手势，在单手握持的场景下，该操作手势较为别扭，舒适性差，操作时握持稳定性差，开启单手模式的难度大，用户体验较差。
再例如，界面的返回、确认、编辑等控件在大折叠屏的上方。用户需要精准点击相应的控件，以完成返回上一级菜单、确认或编辑等操作。而大折叠屏上方的区域是单手握持的场·景下，用户手指很难触及的盲区，从而使得握持稳定性、舒适性差，影响了使用效率和用户体验。
再例如，在刷新页面时，通常需要关闭网页、应用等当前显示的页面，退回到上一步，再次打开重新加载此页面，从而达到刷新的目的。该种交互方式的步骤较多，时间成本较高。
发明内容
本申请实施例提供一种基于折叠屏的交互方法及设备，能够在用户握持情况下通过更为舒适自然的交互方式，触发特定的操作或功能，提高用户使用体验。
为达到上述目的，本申请实施例采用如下技术方案：
一方面，本申请实施例提供了一种基于折叠屏的交互方法，应用于具有折叠屏的电子设备，折叠屏包括第一子屏和第二子屏，该方法包括：电子设备确定满足预设条 件。而后，电子设备执行预设操作。其中，预设条件包括：在预设时长内，检测到用户针对电子设备的触控操作，且通过传感器检测到第一子屏和第二子屏之间的夹角的大小发生了变化；变化包括夹角增大或夹角减小。
其中，在用户握持电子设备的场景下，拇指通常会自然地位于电子设备附近。因而，用户可以在握持时自然地针对电子设备进行触控操作和折叠操作。从而可以在握持场景下，提供一种与折叠屏进行自然交互的方式，触发执行预设操作或触发开启预设功能。
在一种可能的设计中，第一子屏和第二子屏之间的夹角变大或变小的变化方向不同，或夹角变化的幅度不同，预设操作也不同。例如，预设操作为调整第一功能。第一子屏和第二子屏之间的夹角变大或变小的变化方向不同，第一功能的调整方向也不同。第一子屏和第二子屏之间的夹角变化的幅度越大，第一功能的调整幅度也越大。
这样，子屏间的夹角变化不同，电子设备执行的预设操作也不同。
在另一种可能的设计中，用户针对折叠屏的触控操作为，用户在折叠屏上的滑动操作。滑动操作的滑动方向或滑动幅度不同，预设操作也不同。例如，预设操作为调整第二功能。滑动操作的滑动方向不同，第二功能的调整方向不同；滑动操作的滑动幅度不同，第二功能的调整幅度也不同。

在另一种可能的设计中，在电子设备执行预设操作之后，该方法还包括：若第一子屏和第二子屏之间的夹角由第一夹角变化为第二夹角，且第一夹角和第二夹角之间的差值小于或者等于第二预设角度，则电子设备自动翻折第一子屏和/或第二子屏，以使得第一子屏和第二子屏之间的夹角由第二夹角恢复为第一夹角。
也就是说，若第一子屏和第二子屏之间的夹角变化的幅度较小，则用户可能只想触发预设操作，并不想在夹角变化后的状态下使用电子设备，因而电子设备可以回弹至夹角变化前的状态。
在另一种可能的设计中，在电子设备执行预设操作之后，该方法还包括：若第一子屏和第二子屏之间的夹角由第一夹角减小为第二夹角，且第二夹角大于等于第三预设角度，则电子设备自动翻折第一子屏和/或第二子屏，以使得第一子屏和第二子屏之间的夹角，由第二夹角恢复为第一夹角。
也就是说，若第一子屏和第二子屏之间的夹角变小，且变小后的夹角仍然较大，则折叠操作的幅度可能较小，用户可能只想触发预设操作，并不想在夹角变化后的状态下使用电子设备，因而电子设备可以回弹至夹角变化前的状态。
在另一种可能的设计中，第一夹角为180°。
也就是说，电子设备可以在展开状态下发生折叠后，还可以回弹至展开状态。
在另一种可能的设计中，在电子设备执行预设操作之后，该方法还包括：若第一子屏和第二子屏之间的夹角由第一夹角增大为第二夹角，且第二夹角小于等于第四预设角度，则电子设备自动翻折第一子屏和/或第二子屏，以使得第一子屏和第二子屏之间的夹角，由第二夹角恢复为第一夹角。
也就是说，若第一子屏和第二子屏之间的夹角变大，且变大后的夹角仍然较小，则折叠操作的幅度可能较小，用户可能只想触发预设操作，并不想在夹角变化后的状态下使用电子设备，因而电子设备可以回弹至夹角变化前的状态。
在另一种可能的设计中，在电子设备确定满足预设条件之前，该方法还包括：电子设备显示第一界面。在电子设备执行预设操作之后，且第二夹角恢复为第一夹角之前，该方法还包括：电子设备响应于预设操作，显示第二界面。在第二夹角恢复为第一夹角之后，该方法还包括：电子设备仍显示第二界面。
这样，在回弹前后，电子设备均显示第二界面。回弹并不会使得预设操作和界面显示撤销或回退。
在另一种可能的设计中，预设条件包括第一子屏和第二子屏之间的夹角由第一夹角变化为第二夹角；在电子设备执行预设操作之后，该方法还包括：若第二夹角恢复为第一夹角，则电子设备撤销预设操作，恢复执行预设操作前所处的状态。
在该方案中，在电子设备发生翻折以使得执行预设操作后，若电子设备撤销该翻折操作，则电子设备可以撤销该预设操作。
在另一种可能的设计中，预设条件包括第一子屏和第二子屏之间的夹角由第一夹角变化为第二夹角。在电子设备确定满足预设条件之前，该方法还包括：电子设备显示第一界面。在电子设备执行预设操作之后，该方法还包括：电子设备响应于预设操作，显示第二界面。若第二夹角恢复为第一夹角，则电子设备恢复显示第一界面。

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描述。其中， 在本申请实施例的描述中，除非另有说明，“/”表示或的意思，例如，A/B可以表示A或B；本文中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，在本申请实施例的描述中，“多个”是指两个或多于两个。
本申请实施例提供了一种基于折叠屏的交互方法，可以应用于具有折叠屏的电子设备。具有折叠屏的电子设备，也称为折叠屏设备。在用户使用折叠屏设备时，折叠屏可以显示用户界面。该折叠屏可包括至少两个子屏。例如，折叠屏可以包括第一子屏和第二子屏。其中，在折叠屏折叠的过程中，第一子屏和第二子屏之间的夹角变小；在折叠屏展开的过程中，第一子屏和第二子屏之间的夹角变大。可以理解的是，该折叠屏被折叠后形成的至少两个子屏，可以为独立存在的多个子屏；也可以为一体结构的一个完整屏，只是被折叠形成了至少两个部分。
若折叠屏设备在预设时长内，检测到用户针对折叠屏设备的触控操作，并且检测到第一子屏和第二子屏之间的夹角的大小发生了变化，则可以执行预设操作或触发预设功能。其中，该预设操作与触控操作和夹角变化相关联。例如，用户针对折叠屏设备的触控操作，可以包括用户针对折叠屏设备的折叠屏的触控操作，或者用户针对折叠屏设备的侧边的按压操作。示例性的，用户针对折叠屏设备的侧边的按压操作可以为，用户针对折叠屏设备的侧边设置的电源键或音量键等按键的按压操作，或者用户针对折叠屏设备的侧边的特定部位(例如上半部分)的按压操作。其中，第一子屏和第二子屏之间的夹角的大小变化，可以包括夹角增大或夹角减小。该预设操作可以是开启单手模式、开启分屏功能或刷新页面等。
在用户握持折叠屏设备的场景下，拇指通常会自然地位于折叠屏设备附近，例如位于折叠屏前方或位于折叠屏的侧边。因而用户可以在握持时自然地针对折叠屏设备进行触控操作，例如针对折叠屏进行触控操作，或针对折叠屏设备的侧边进行按压操作。在握持场景下，其他手指通常会自然地位于折叠屏的背面，因而可以在握持时自然地推动折叠屏折叠。也就是说，在握持场景下，用户可以通过该种自然的方式，与折叠屏进行交互，从而触发执行预设操作或触发开启预设功能。
在一些实施例中，折叠屏可以为柔性折叠屏。其中，柔性折叠屏包括采用柔性材质制作的折叠轴。该柔性折叠屏的部分或全部采用柔性材质制作。例如：该柔性折叠屏中只有可折叠的部分(如折叠轴)采用柔性材质制作，其它部分采用刚性材质制作；或者，该柔性折叠屏全部采用柔性材质制作。该折叠屏可沿折叠轴折叠形成至少两个子屏。
示例性的，图2A示出了一种具有折叠线020的柔性折叠屏。该折叠屏沿折叠线020纵向折叠后，可形成图2B-图2D所示的子屏021和子屏022。例如，该折叠屏设备可以为折叠屏手机。
再示例性的，如图3A所示的柔性折叠屏，可以包括折叠线030和折叠线031。在沿折叠线030纵向折叠后，可以形成如图3B所示的子屏032、子屏033和子屏034。例如，该折叠屏设备可以为折叠屏手机。
再示例性的，如图4A所示的柔性折叠屏，在沿折叠线040横向折叠后，可以形成如图4B所示的子屏041、和子屏042。例如，该折叠屏设备在折叠状态可以为手机，在展开 状态可以为平板电脑。
其中，折叠屏中相邻两个子屏之间的夹角大于或者等于0°且小于或者等于180°。折叠屏可以包括展开状态、折叠状态和半折叠状态。
展开状态表示折叠屏完全展开，即折叠屏中相邻两个子屏之间的夹角为180°。例如，图2A、图3A和图4A表示折叠屏展开状态的示意图。示例性的，如图2A所示，子屏021和子屏022之间的夹角φ为180°。
折叠状态表示折叠屏完全折叠，即折叠屏中相邻两个子屏之间的夹角为0°。例如，图4C表示折叠屏折叠状态的示意图，子屏041和子屏042之间的夹角为0°。
介于展开状态和折叠状态之间的状态，可以称为半折叠状态，即折叠屏中相邻两个子屏之间的夹角介于0°和180°之间。例如，图2B-图2D，以及图3B和图4B表示折叠屏半折叠状态的示意图。示例性的，如图2B-图2D所示，子屏021和子屏022之间的夹角φ大于0°且小于180°。
在其他一些实施例中，折叠屏也可以为多屏折叠屏。该多屏折叠屏可包括至少两个子屏。该至少两个子屏是独立的显示屏，可依次通过折叠轴连接，可分别绕折叠轴转动，实现多屏折叠屏的折叠。示例性的，如图4D所示，折叠屏设备包括折叠轴043，子屏044，以及与子屏044独立的另一子屏045。子屏044与子屏045可绕折叠轴043转动。
在本申请的实施例中，折叠屏可以是单面屏(即只有一面可以显示用户界面)也可以是双面屏(即相对的两面均可显示用户界面)。
对于单面折叠屏来说，折叠屏朝可显示用户界面的一面(即单面折叠屏的正面)进行翻折的情况，可以称为正向翻折；折叠屏朝可显示用户界面的一面的相对面(即单面折叠屏的背面)进行翻折的情况，可以称为反向翻折。例如，图2B-图4C表示正向翻折的示意图，图4D表示反向翻折的示意图。折叠屏设备可以确定当前是正向翻折还是反向翻折。
正向翻折或反向翻折都可以使得折叠屏实现半折叠状态。对于正向翻折场景下的半折叠状态，两个相邻子屏上具有显示功能的那一面之间的夹角大于0°且小于180°。对于反向翻折场景下的半折叠状态，两个相邻子屏上不具有显示功能的那一面之间的夹角大于0°且小于180°。
例如，该折叠屏设备可以是手机、平板电脑、桌面型、膝上型、手持计算机、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本，以及蜂窝电话、个人数字助理(personal digital assistant，PDA)、增强现实(augmented reality，AR)\虚拟现实(virtual reality，VR)设备等具有折叠屏的设备。本申请实施例对折叠屏设备的具体类型不予限定。

在本申请的实施例中，每个子屏都可以设置有陀螺仪传感器180B，用于测量所在子屏的朝向(即朝向的方向向量)。例如，在图2B所示的电子设备中，子屏021和子屏022中均包括陀螺仪传感器180B，分别用于测量子屏021和子屏022的朝向。电子设备根据每个子屏的朝向的角度变化，可以确定相邻子屏之间的夹角。
示例性的，以电子设备100为图2B所示的折叠屏设备为例。电子设备100的折叠屏可折叠形成图6A所示的子屏061和子屏062。转轴机构196设置于折叠线的位置。子屏061中设置有陀螺仪传感器1，子屏062中设置有陀螺仪传感器2。
其中，陀螺仪传感器的坐标系是地理坐标系。如图6B所示，地理坐标系的原点O位于运载体(即包含陀螺仪传感器的设备，如电子设备100)所在的点，x轴沿当地纬线指向东(E)，y轴沿当地子午线线指向北(N)，z轴沿当地地理垂线指向上，并与x轴和y轴构成右手直角坐标系。其中，x轴与y轴构成的平面即为当地水平面，y轴与z轴构成的平面即为当地子午面。因此，可以理解的是，陀螺仪传感器的坐标系是：以陀螺仪传感器为原点O，沿当地纬线指向东为x轴，沿当地子午线线指向北为y轴，沿当地地理垂线指向上(即地理垂线的反方向)为z轴。
电子设备100利用每个子屏中设置的陀螺仪传感器，便可测量得到每个子屏在其设置的陀螺仪传感器的坐标系中的朝向的方向向量。例如，参考如图6A所示的电子设备的侧视图，电子设备测量得到的子屏061在陀螺仪传感器1的坐标系中的朝向的方向向量为向量z1，子屏062在陀螺仪传感器2的坐标系中的朝向的方向向量为向量z2。电子设备利用公式(1)：
Figure PCTCN2020102810-appb-000001
便可计算出向量z1与向量z2的夹角θ。
又根据图6A可知，由于向量z1与子屏061垂直，向量z2与子屏062垂直，因此，可以得到子屏061与子屏062的夹角φ＝180°-θ。即电子设备根据测量得到的子屏061在陀螺仪传感器1的坐标系中的朝向的方向向量(即向量z1)和子屏062在陀螺仪传感器2的坐标系中的朝向的方向向量(即向量z2)，便可确定出子屏061与子屏062的夹角φ。当夹角φ大于0°且小于180°时，电子设备当前为正向翻折对应的半折叠状态。当夹角φ大于180°且小于360°时，电子设备当前为反向翻折对应的半折叠状态。
需要说明的是，虽然子屏061和子屏062中设置的陀螺仪传感器的位置并不重叠，即子屏061和子屏062的陀螺仪传感器的坐标系的原点并不重叠，但是，两个坐标系的x轴、y轴、z轴是平行的，从而可以认为子屏061和子屏062中设置的陀螺仪传感器的坐标系是平行的。这样一来，虽然向量z1和向量z2不在同一个坐标系，但是因为两个坐标系的各轴平行，因此，仍可通过上述公式(1)计算向量z1与向量z2的夹角θ。
在一些实施例中，还可以由其他一个或多个传感器配合，测量子屏061与子屏062的夹角α。例如，折叠屏的每个子屏中均可设置一个加速度传感器。电子设备100(如处理器110)可利用加速度传感器测量每个子屏被转动时的运动加速度；然后根据测量得到的运动加速度计算一个屏相对于另一个屏转动的角度，即子屏061与子屏062的夹角φ。
在另一些实施例中，上述陀螺仪传感器可以是由其他多个传感器配合形成的虚拟陀螺仪传感器。该虚拟陀螺仪传感器可用于计算折叠屏的相邻子屏的夹角，即子屏061与子屏 062的夹角φ。
此外，在本申请的实施例中，陀螺仪传感器180B、加速度传感器180E等传感器还可以用于确定各子屏的状态，从而确定折叠屏当前为正向翻折状态，还是反向翻折状态。
例如，子屏上的陀螺仪传感器180B，可以测得子屏翻折时的角速度，对角速度进行积分可以得到子屏相对于特定坐标系(例如地理坐标系)的夹角，从而可以得到子屏的姿态。根据子屏的姿态可以获知子屏的朝向。根据各子屏的朝向，可以获知折叠屏当前是正向翻折状态或反向翻折状态。

转轴机构196用于实现折叠屏在第一子屏和第二子屏之间的夹角变化后，回弹至该夹角变化前的状态或者回弹至展开状态。转轴机构196可以位于折叠屏的折叠边或折叠轴所在的位置。转轴机构196可以包括机械转轴机构，电子转轴机构，或两者的组合。
例如，图7A示出了一种转轴机构196的结构示意图，该转轴机构196为机械转轴。机械转轴可以包括一组凸轮A、凸轮B，轴心，和套在轴心上的弹簧。其中，凸轮A与轴心固定，凸轮B通过连杆与第一子屏连接，凸轮A与凸轮B接触，凸轮B与弹簧接触。在初始状态，凸轮A与凸轮B为平面接触，弹簧对凸轮B的力F的方向与接触面垂直， 凸轮B和凸轮A不会发生相对移动，与凸轮B连接的第一子屏不发生翻转。其中，该初始状态为预设的状态，本申请实施例中以初始状态为展开状态为例进行说明。
在一些实施例中，机械转轴还可以包括一组凸轮A’、凸轮B’，轴心，和套在轴心上的弹簧。凸轮B’与第二子屏连接。在展开状态，凸轮A’与凸轮B’为平面接触，凸轮B’和凸轮A’不会发生相对移动，与凸轮B’连接的第二子屏也不会发生翻转，因而折叠屏可以保持展开状态不变。
在第一子屏发生翻折时，凸轮B发生旋转。若第一子屏翻折的幅度较小，第一子屏与第二子屏之间的夹角变化的幅度小于或者等于预设角度1；或者，翻折使得该夹角减小，且翻折后第一子屏和第二子屏之间的夹角大于预设角度2，则如图7B所示，凸轮B选择的幅度较小，凸轮B与凸轮A之间形成斜面接触。弹簧对凸轮B的力F的方向与接触面不垂直。在力F的作用下，凸轮B与凸轮A相接触的斜面发生相对滑动，凸轮B往回旋转至与凸轮A平面接触，从而使得第一子屏回弹至折叠屏的展开状态。
若第一子屏翻折的幅度较大，第一子屏与第二子屏之间的夹角减小的幅度大于预设角度2；或者，翻折后第一子屏和第二子屏之间的夹角小于或者等于预设角度2，则如图7C所示，凸轮B旋转的幅度较大，凸轮B与凸轮A之间形成平面接触。凸轮B和凸轮A不会发生相对移动，与凸轮B连接的第一子屏不发生翻转。从而可以保持折叠屏当前的翻折状态不变。
第二子屏翻折的情况与第一子屏翻折的情况类似，此处不予赘述。
再例如，图7D示出了另一种转轴机构196的结构示意图，该转轴机构196为电子转轴。电子转轴包括转子和(定子)。转子和定子分别与第一子屏和第二子屏刚性连接，当电机转动时，可以使得转子和定子相对转动，从而带动第一子屏和第二子屏相对翻折。示例性的，转子与第一子屏刚性连接。在第一子屏发生翻折时，若第一子屏与第二子屏之间的夹角减小的幅度小于或者等于预设角度1；或者，翻折后第一子屏和第二子屏之间的夹角小于或者等于预设角度2，则电机可以接通反向电流，电机发生反转，带动第一子屏向后翻折，使得折叠屏回弹至展开状态或回弹至第一子屏和第二子屏夹角减小前的状态。当电机接通正向电流时，电机发生正转，带动第一子屏向前翻折，使得折叠屏折叠。
在本申请的实施例中，电子设备100中的显示屏194可以为折叠屏，该折叠屏可以包括第一子屏和第二子屏。用户可以翻折或展开折叠屏。陀螺仪传感器180B等部件可以检测第一子屏和第二子屏之间的夹角及变化。触摸传感器180K等传感器可以检测到用户针对折叠屏的触控操作。电源键或音量键响应于用户的按压操作，将按压事件上报给处理器。处理器110在预设时长内，若确定检测到用户针对折叠屏的触控操作，或用户针对电源键或音量键的按压操作，且第一子屏和第二子屏之间的夹角发生了变化；则通知相关应用执行预设操作。
在执行预设操作后，若处理器确定第一子屏与第二子屏之间的夹角变化的幅度小于或者等于预设角度1；或者若该夹角变小且变小后的当前第一子屏与第二子屏之间的夹角大于预设角度2；或者若该夹角变大且变大后的当前第一子屏与第二子屏之间的夹角小于预设角度3，则还可以指示电子转轴带动子屏转动，从而使得折叠屏回弹至展开状态或上述夹角变化前的状态。

例如，该触控操作也可以是滑动操作、点击操作、按压操作或触摸操作等。其中，该点击操作可以包括单击操作、双击操作或多次点击操作等。比如，该触控操作可以是用户针对折叠屏上的图标的点击操作。再比如，该触控操作可以是用户针对折叠屏上的控件的滑动操作。
在一些实施例中，该预设操作和触控操作可以是折叠屏设备预先设置的，或者用户自定义设置的。在一些实施例中，触控操作不同，触发执行的预设操作也不同。示例性的，折叠屏设备可以显示如图8所示的设置界面，以方便用户设置折叠操作和触控操作可触发的预设操作。
在另一些实施例中，触控操作可以是任意用户接触折叠屏设备的操作。这样，折叠屏设备一旦检测到用户针对折叠屏屏的任意触控操作，就可以确定检测到用户针对折叠屏的触控操作。因而，可以方便用户进行盲操作，提高用户使用体验。
在一些实施例中，折叠屏设备在确定满足预设条件1后，执行预设操作。该预设条件1可以包括：在预设时长内，通过传感器检测到第一子屏和第二子屏之间的夹角的大小发生了变化，即检测到折叠屏的折叠操作；且检测到用户针对折叠屏的触控操作。
也就是说，折叠屏设备检测到第一子屏和第二子屏之间的夹角的大小发生变化，与检测到用户针对折叠屏的触控操作之间的时间间隔，小于或者等于预设时长。该预设时长较短，例如可以为2s(秒)。
其中，折叠屏设备检测子屏间的夹角是否发生变化的方式可以有多种。例如，折叠屏设备可以通过上述陀螺仪传感器或加速度传感器检测夹角是否发生变化。再例如，折叠屏设备还可以通过转动轴传感器、触摸屏电容变化或霍尔传感器等方式检测夹角是否发生变化。可以理解是，也可以把夹角的变化替代为检测上述一个或者多个传感器的模拟/数字信号量的数据变化，从而根据该模拟/数字信号量的数据变化，确定夹角是否发生变化。
若折叠屏设备第一子屏和第二子屏之间的夹角发生了变化，则折叠屏发生了折叠操作。折叠屏设备可以检测第一子屏和第二子屏之间的夹角的变化情况。其中，折叠屏设备检测第一子屏和第二子屏之间的夹角的变化情况，可以根据陀螺仪传感器、加速度传感器等检测到的数据，直接计算夹角的变化；也可以通过检测转轴机构的变动等间接方式进行检测，并且实际计算也可以基于变动前后的相对情况进行等效运算。折叠屏设备可以根据第一子屏和第二子屏之间的夹角的变化情况，确定该夹角是增大了还是减小了。
折叠屏设备在预设时长内检测到第一子屏和第二子屏之间的夹角的大小发生了变化，且检测到用户针对折叠屏的触控操作可以包括以下情况：
折叠屏设备同时检测到第一子屏和第二子屏之间的夹角的大小发生了变化，以及用户针对折叠屏任意区域的触控操作。并且，用户可对折叠屏任意区域进行盲操作，从而可以提高操作效率和用户使用体验。
或者，折叠屏设备在预设时长内先检测到第一子屏和第二子屏之间的夹角的大小发生了变化，又检测到用户针对折叠屏任意区域的触控操作。即，折叠屏设备检测到夹角的大小发生了变化，与检测到用户针对折叠屏任意区域的触控操作之间的时间间隔，小于或者等于较短的预设时长。折叠屏设备在检测到夹角的大小发生了变化后，很快又检测到用户针对折叠屏任意区域的触控操作。并且，用户可对折叠屏任意区域进行盲操作，从而可以提高操作效率和用户使用体验。
或者，折叠屏设备在预设时长内先检测到用户针对折叠屏的触控操作，又检测到第一子屏和第二子屏之间的夹角的大小发生了变化。即，折叠屏设备在检测到用户针对折叠屏任意区域的触控操作后，很快又检测到子屏间的夹角的大小发生了变化。此外，由于用户可以通过针对折叠屏上的触控操作(例如点击应用图标)正常使用折叠屏设备，因而为了避免误操作，该种情况下的触控操作可以是用户针对折叠屏上空白区域的操作。
在用户握持折叠屏设备的场景下，用户的拇指通常会自然地位于折叠屏前方，可以自然地针对折叠屏进行触控操作。并且，在用户握持折叠屏设备的场景下，其他手指通常会自然地位于折叠屏的背面(也即折叠屏设备远离用户面部的一方)。位于折叠屏背面的手指，例如食指，可以自然地推动折叠屏上半部分的子屏，向折叠屏的前方(也即折叠屏设备朝向用户面部的一方)翻折。
也就是说，在用户握持折叠屏设备时，用户可以很自然地对折叠屏进行折叠，并自然地针对折叠屏任意区域或任意空白区域进行触控操作，从而触发折叠屏设备执行预设操作，因而是一种握持场景下的自然交互方式；而不需要用户刻意地去执行用于触发预设操作的操作。
并且，采用本申请实施例提供的自然交互方式，用户不需要像现有交互方式那样专门记忆特定手势和特定操作区域，不需要刻意去执行复杂的特定手势，也不需要在手指难以触及的盲区进行操作。因而，该种自然交互方式便于操作，握持更稳定，舒适性更好，触发预设操作的成功率更高，用户体验更好。
在一些实施例中，在第一子屏和第二子屏之间的夹角变化的角度，大于或者等于预设角度0(例如可以为3°)时，折叠屏设备才触发执行预设操作。具体的，若第一子屏和第二子屏之间的夹角增大了第一角度，且第一角度大于或者等于预设角度0；或者，第一子屏和第二子屏之间的夹角减小了第二角度，且第二角度大于或者等于预设角度0。
其中，由于第一子屏和第二子屏之间的夹角的大小变化太小时(例如变化了零点几度)，可能是折叠屏设备发生了抖动或晃动等，且该变化不易被折叠屏设备准确地检测到，从而容易导致误操作。因而，折叠屏设备在检测到子屏间的夹角发生明显变化时，才触发执行预设操作，可以提高触发精度。
举例来说，预设操作为开启单手模式的操作，触控操作为按压操作。在用户握持场景下，拇指自然地位于折叠屏的前面。在用户向前翻折第一子屏时，为了保持折叠屏设备握持稳定，避免滑落，拇指会自然地按住折叠屏，即自然地执行该按压操作，而不用刻意去制作该触控操作。
示例性的，折叠屏设备开始处于如图9A所示的展开状态。折叠屏设备在预设时长内检测到第一子屏和第二子屏之间的夹角变小后，折叠屏设备处于如图9B所示的半折叠状态。在该预设时长内折叠屏设备还检测到用户在折叠屏屏上的按压操作，则折叠屏设备执行预设操作，开启单手模式。并且，如图9B所示，在开启单手模式后，折叠屏设备还可以将界面显示范围缩小至右下角(或左下角)，以方便用户单手操作。
再示例性的，折叠屏设置开始处于如图9C所示的状态。响应于用户的折叠操作后，第一子屏和第二子屏之间的夹角变大。折叠屏设备在预设时长内检测到第一子屏和第二子屏之间的夹角变大，折叠屏设备处于如图9D所示的状态。在该预设时长内折叠屏设备还检测到用户在折叠屏屏上的按压操作，则折叠屏设备执行预设操作，开启单手模式。并且，如图9D所示，在开启单手模式后，折叠屏设备还可以将界面显示范围缩小至右下角(或左下角)，以方便用户单手操作。
需要说明的是，与图9D相比，图9C所示的折叠屏的折叠程度更大，但使得折叠屏由图9C所示的状态变化为图9D所示的状态的折叠屏的动作，也可以称为折叠操作。
在本申请的实施例中，该预设操作可以是固定的，在各应用状态下均为同一操作；也可以是随着当前应用状态的变化而动态变化的不同操作。例如，该应用状态的变化可以包括折叠屏设备当前使用的应用的变化，当前显示的应用界面的变化等。
例如，在满足预设条件1时，若当前正在使用的应用为视频、浏览器、通讯、理财、股票等需要实时更新数据的应用，则预设操作可以为刷新当前页面。
再例如，在满足预设条件1时，若当前正在显示的用户界面为阅读器的页面，则该预设操作可以为向后翻页。若当前正在显示的用户界面为浏览器器的网页，则该预设操作可以为向上滚动页面。
再例如，在满足预设条件1时，若眼部追踪传感器确定眼部已锁定相应的区域，则该预设操作可以为点击该区域内的控件。
在其他一些实施例中，预设操作还可以随着折叠屏的折叠速度、折叠角度或折叠幅度等因素的不同而不同。
例如，在一些实施例中，第一子屏和第二子屏之间的夹角变化的幅度不同，预设操作也不同。例如，第一子屏和第二子屏之间的夹角变小的幅度越大，开启单手模式后，界面显示范围也越小。第一子屏和第二子屏之间的夹角变小的幅度越小，开启单手模式后，界面显示范围也越大。
在另一些实施例中，在满足预设条件1后，第一子屏和第二子屏之间的夹角不同，预设操作也不同。例如，在第一子屏和第二子屏之间的夹角变小，开启单手模式后，若该夹角当前的角度越小，则界面显示范围也越小；若该夹角当前的角度越大，界面显示范围也越大。在折叠屏不断折叠的过程中，界面显示范围可以越来越小。
示例性的，在满足预设条件1后，折叠屏为如图9D所示的半折叠状态。图9D所示的第一子屏和第二子屏之间的夹角大于图9B所示的夹角。因而，在开启单手模式后，图9D所示的界面显示范围大于图9B所示的界面显示范围。
在其他示例中，预设操作为调节屏幕亮度等操作。在满足预设条件1后，第一子屏和第二子屏之间的夹角越大，屏幕亮度越大；第一子屏和第二子屏之间的夹角越小，屏幕亮度越小。在折叠屏不断折叠的过程中，屏幕亮度可以越来越小。
在其他一些实施例中，预设操作包括开启左手单手模式或开启右手单手模式。折叠屏设备可以根据触控操作在折叠屏上的滑动轨迹、滑动方向、触控面积、手指的特征、点击的图标或触控位置等确定开启左手单手模式或开启右手单手模式。
其中，当用户左手握持折叠屏设备时，用户通常想要开启左手单手模式。当用户右手握持折叠屏设备时，用户通常想要开启右手单手模式。
例如，触控操作为滑动操作。当用户左手握持折叠屏设备时，拇指可以自然地在折叠屏的左半部分(即左半屏)滑动。当用户右手握持折叠屏设备时，拇指可以自然地在折叠屏的右半部分(即右半屏)滑动。因而，预设条件1还可以包括用户在折叠屏上的滑动操作的滑动轨迹大部分位于左半部分，即滑动轨迹在左半部分的长度大于在右半部分的长度，对应的预设操作为开启左手单手模式。或者，预设条件1还可以包括用户在折叠屏上的滑动操作的滑动轨迹大部分位于右半部分，即滑动轨迹在左半部分的长度小于或者等于在右半部分的长度，对应的预设操作为开启右手单手模式。
示例性的，如图10A所示，折叠屏设备检测到用户在折叠屏上的滑动轨迹大部分位于左半部分的情况下，开启左手单手模式。如图10B所示，折叠屏设备检测到用户在折叠屏上的滑动轨迹大部分位于右半部分的情况下，开启右手单手模式。
再例如，触控操作为滑动操作。预设条件1还包括用户在折叠屏上的滑动操作的滑动方向大体为从上向下，对应的预设操作为开启右手单手模式。或者，预设条件1还包括用户在折叠屏上的滑动操作的滑动方向大体为从下向上，对应的预设操作为开启左手单手模式。
再例如，触控操作为滑动操作。当用户左手握持折叠屏设备时，可能更习惯在折叠屏上从右向左滑动。当用户右手握持折叠屏设备时，可能更习惯在折叠屏上从左向右滑动。因而，预设条件1还包括用户在折叠屏上的滑动操作的滑动方向大体为从右向左(例如从右到左，从右下角到左上角，或从右上角到左下角等)，对应的预设操作为开启左手单手模式。或者，预设条件1还包括用户在折叠屏上的滑动操作的滑动方向大体为从左向右(例如从左到右，从左下角到右上角，或从左上角到右下角等)，对应的预设操作为开启右手单手模式。
再例如，当用户左手握持折叠屏设备时，拇指离左半部分更近，更容易在左半部分触控折叠屏。当用户右手握持折叠屏设备时，拇指离右半部分更近，更容易在右半部分触控折叠屏。
示例性的，预设条件1还包括用户在折叠屏上的触控操作的触控面积(即触控时用户手机与折叠屏的接触面积)大部分位于左半部分，即触控操作在折叠屏的左半部分的触控面积大于在右半部分的触控面积，对应的预设操作为开启左手单手模式。或者，预设条件1还包括用户在折叠屏上的触控操作的触控面积大部分位于右半部分，即触控操作在折叠屏的左半部分的触控面积小于或者等于在右半部分的触控面积，对应的预设操作为开启右手单手模式。
举例来说，如图11A所示，在折叠屏设备检测到用户在折叠屏上的按压操作的按压面积(由图中的黑色圆点表示)大部分位于左半部分的情况下，折叠屏设备开启左手单手模式。如图11B所示，在折叠屏设备检测到用户在折叠屏上的按压操作的按压面积(由图中的黑色圆点表示)大部分位于右半部分的情况下，折叠屏设备开启右手单手模式。
再示例性的，预设条件1还包括用户的触控区域位于第二子屏的左上角(或第一子屏的左下角)，对应的预设操作为开启左手单手模式。或者，预设条件1还包括用户的触控区域位于第二子屏的右上角(或第一子屏的右下角)，对应的预设操作为开启右手单手模式。
再例如，触控操作为按压操作。当预设条件1还包括按压操作的按压特征为第一特征时，预设操作为开启左手单手模式。当预设条件1还包括按压特征为第二特征，预设操作为开启右手单手模式。其中，按压特征包括按压力度特征，按压位置特征，或按压面积特征中的一个或多个。
其中，按压位置为用户进行按压操作时，手指与折叠屏接触区域的中心位置。示例性的，第一特征为按压位置位于左半屏，第二特征为按压位置位于右半屏。即，若按压位置位于左半屏，则开启左手单手操作；若按压位置位于右半屏，则开启右手单手模式。
示例性的，第一特征为按压力度大于或者等于预设力度值1，第二特征为按压力度小于预设力度值1且大于或者等于预设力度值2。即，若按压力度大于或者等于预设力度值1，则开启左手单手操作；若按压力度小于预设力度值1且大于或者等于预设力度值2，则开启右手单手模式。
其中，按压面积特征可以包括单次按压面积的特征或者多种按压面积的特征，具体可以包括按压面积的大小，按压面积的形状，按压面积的分布情况等。示例性的，该按压面积可以为上述图11A和图11B所示的触控面积。
再例如，预设条件1还包括触控操作对应的手指的特征为第三特征，预设操作为开启左手单手模式；或者，预设条件还包括触控操作对应的手指的特征为第四特征，预设操作为开启右手单手模式。其中，手指的特征包括与折叠屏接触的手指的指纹或手指的形状。
其中，用户左手的指纹特征与右手的指纹特征不同。例如，指纹纹路的大体绕行方向，指纹纹路的具体细节等指纹特征不同。示例性的，若折叠屏设备确定按压时手指的指纹为左手的指纹，则触发左手单手模式；若折叠屏设备确定按压时手指的指纹为右手的指纹，则触发右手单手模式。
再示例性的，与折叠屏接触的拇指的形状大体为沿左斜线方向分布，即大体为“/”方向。当用户右手握持折叠屏设备时，与折叠屏接触的拇指的形状大体为沿右斜线方向分布，即大体为“\”方向。因而，当拇指形状大体为左斜线方向分布时，对应的预设操作为开启左手单手模式。当拇指形状大体为右斜线方向分布时，对应的预设操作为开启右手单手模式。
举例来说，如图11C所示，折叠屏设备检测到用户在折叠屏上的按压操作的手指形状大体为左斜线方向分布的情况下，开启左手单手模式。如图11D所示，折叠屏设备检测到用户在折叠屏上的按压操作的手指形状大体为右斜线方向分布的情况下，开启右手单手模式。
再例如，该触控操作为用户针对折叠屏上的图标的点击操作。示例性的，预设条件1还包括检测到用户针对左半屏图标的点击操作，对应的预设操作为开启左手单手模式。或者，预设条件1还包括检测到用户针对右半屏图标的点击操作，对应的预设操作为开启右手单手模式。
再示例性的，预设条件1还包括检测到用户针对特定图标1的点击操作，对应的预设 操作为开启左手单手模式。或者，预设条件1还包括检测到用户针对特定图标2的点击操作，对应的预设操作为开启右手单手模式。
再示例性的，预设条件1还包括检测到用户针对第二子屏左上角(或第一子屏左下角)的图标的点击操作，对应的预设操作为开启左手单手模式。或者，预设条件1还包括检测到第二子屏右上角(或第一子屏右下角)的图标的点击操作，对应的预设操作为开启右手单手模式。
在另一些实施例中，折叠屏设备可以结合折叠屏的折叠操作，以及用户针对折叠屏设备的侧边的按压操作，执行预设操作。
例如，在一些实施例中，折叠屏设备在确定满足预设条件2后，执行预设操作。该预设条件2可以包括：在预设时长(例如2s)内，检测到第一子屏和第二子屏之间的夹角变小，即检测到折叠屏的折叠操作；且检测到用户针对折叠屏设备的侧边的电源键或音量键的按压操作。
其中，用户针对电源键或音量键的按压操作可以是单次按压、多次按压或长按等。在用户握持折叠屏设备的场景下，用户的拇指和中指可以自然地位于折叠屏设备的侧边位置，因而可以自然地按压侧边位置，例如按压侧边位置设置的电源键或音量键。并且，在用户握持折叠屏设备的场景下，其他手指通常会自然地位于折叠屏的背面。位于折叠屏背面的食指等手指，可以自然地推动折叠屏上半部分的子屏，向折叠屏的前方翻折。
在一些实施例中，当预设操作包括开启左手单手模式或开启右手单手模式时，折叠屏设备可以根据用户按压的按键为电源键或音量键，用户按压的按键为音量键的上键或下键，或按压次数等，确定开启左手单手模式或开启右手单手模式。
例如，预设条件2包括检测到用户针对音量键(上键或下键)的按压操作，对应的预设操作为开启右手单手模式。或者，预设条件2包括检测到用户针对电源键的按压操作，对应的预设操作为开启左手单手模式。
示例性的，折叠屏设备在检测到用户按压如图12A所示的电源键1201的情况下，开启左手单手模式。折叠屏设备在检测到用户按压音量键1202的情况下，如图12B所示，开启右手单手模式。
再例如，预设条件2包括检测到用户针对音量键的下键的按压操作，对应的预设操作为开启左手单手模式。或者，预设条件2包括检测到用户针对音量键的上键的按压操作，对应的预设操作为开启右手单手模式。
再例如，预设条件2包括检测到用户针对电源键的快速按压两次的操作，对应的预设操作为开启左手单手模式。或者，预设条件2包括检测到用户针对电源键按压一次的操作，对应的预设操作为开启右手单手模式。
在另一些实施例中，折叠屏设备可以不结合用户针对折叠屏设备的触控操作，而直接响应于折叠屏的折叠操作，执行上述预设操作。该预设操作与子屏间的夹角变化相关联。该种交互方式更为简单自然，预设操作的触发成功率高，用户体验更好。
例如，折叠屏设备确定满足预设条件3后，执行预设操作。该预设条件3可以包括：折叠屏设备检测到第一子屏和第二子屏之间的夹角的大小发生了变化。
在用户握持折叠屏设备的场景下，用户除拇指以外的其他手指通常会自然地位于折叠屏的背面。位于折叠屏背面的食指等手指，可以自然地推动折叠屏上半部分的子屏，向折 叠屏的前方翻折。也就是说，在用户握持折叠屏设备时，用户可以很自然地对折叠屏进行折叠，从而触发折叠屏设备执行预设操作，而不需要用户刻意去执行用于触发预设操作的其他操作。因而，该种自然的交互方式便于操作，握持稳定，舒适性更好，触发预设操作的成功率更高，用户体验更好。
在本申请的实施例中，预设操作与用户针对折叠屏设备的触控操作以及子屏间的夹角的变化相关联，具体可以包括：预设操作与以下一项或多项参数相关联：
例如，用户针对折叠屏设备的折叠屏的触控操作为，用户在折叠屏上的滑动操作。比如，可以为用户针对折叠屏上的控件的滑动操作。预设操作与用户在折叠屏上的滑动方向和滑动幅度相关联。示例性的，该预设操作为调整折叠屏的显示亮度。折叠屏设备检测到用户向下(或向左)滑动时，调小显示亮度，即显示亮度的调整方向为减小；折叠屏设备检测到用户向上(或向右)滑动时，增大显示亮度，即显示亮度的调整方向为增大。并且，折叠屏设备检测到用户在折叠屏上滑动的幅度越大，则显示亮度调整(调大/调小)的幅度越大；折叠屏设备检测到用户在折叠屏上滑动的幅度越小，显示亮度调整的幅度越小。
再例如，折叠屏设备的侧边位置设置有相应的传感器可以检测到用户的滑动操作。预设操作与用户针对折叠屏设备的侧边的滑动操作的滑动方向和滑动幅度相关联。示例性的，该预设操作为调整显示亮度。折叠屏设备检测到用户在侧边向下滑动时，调小显示亮度；折叠屏设备检测到用户在侧边向上滑动时，增大显示亮度。折叠屏设备检测到用户在侧边的滑动幅度越大，则显示亮度调整的幅度越大；折叠屏设备检测到用户在侧边的滑动幅度越小，则显示亮度调整的幅度越小。
再例如，折叠屏设备的侧边设置有可拨动的控件，预设操作与用户针对该控件的拨动方向和拨动幅度相关联。示例性的，该预设操作为调整音量。若折叠屏设备检测到用户从上往下拨动该控件，则调小音量；若折叠屏设备检测到用户从下往上拨动该控件，则增大音量。若折叠屏设备检测到针对该控件的拨动幅度较大，则音量的调整幅度越大；若折叠屏设备检测到针对该控件的拨动幅度较小，则音量的调整幅度较小。
再例如，预设操作与第一子屏和第二子屏之间的夹角变化的幅度相关联。示例性的，该预设操作为调整音量。第一子屏和第二子屏之间的夹角的变化幅度越大，则音量调整幅度越大；第一子屏和第二子屏之间的夹角的变化幅度越小，则音量调整幅度越小。
再例如，预设操作与第一子屏和第二子屏之间的夹角变化后的大小相关联。示例性的，该预设操作为调整音量。变化后的第一子屏和第二子屏之间的夹角越大，则调整后的音量越大；变化后的第一子屏和第二子屏之间的夹角越小，则调整后的音量越小。
再例如，预设操作与用户针对折叠屏设备侧边设置的控件的拨动幅度，以及第一子屏和第二子屏之间的夹角变化相关联。
再例如，预设操作与用户在折叠屏上的滑动方向、滑动幅度，以及第一子屏和第二子屏之间的夹角变化的幅度相关联。
其中，当预设操作与以上多项相关联时，折叠屏设备还可以通过预设操作进行多方面的控制或调整。
示例性的，折叠屏包括第一控件和第二控件，第一控件用于调整第一功能，第二控件用于调整第二功能，预设操作包括调整第一功能和第二功能。第一功能与第一子屏和第二子屏之间的夹角变化相关联。触控操作为针对第二控件的滑动操作，第二功能与滑动操作 的滑动方向和滑动幅度相关联。其中，第一功能和第二功能可以是同一功能的两个子功能，也可以是不同方面的功能，本申请实施例不予限定。
举例来说，如图13A中的(a)所示，在图片处理APP的用户界面上，包括用于调整饱和度(即第一功能)的控件1301(即第一控件)，以及用于调整对比度(即第二功能)的控件1302(即第二控件)。当折叠屏设备检测到用户长按(或点击等其他操作)控件1301的操作后，如图13A中的(b)所示，控件1301被锁定。而后，如图13A中的(c)所示，若折叠屏设备在预设的时间长度内(例如1s)检测到子屏间的夹角发生了变化，则折叠屏设备确定子屏间的夹角变化与被锁定的控件1301的功能相绑定。且对比图13A中的(b)与(a)可知，夹角变化后，饱和度的大小发生了变化。折叠屏设备确定子屏间的夹角变化可以用于调整饱和度。即，饱和度的调整与子屏间的夹角变化相关联。比如，变化后的子屏间的夹角越大，则调整后的饱和度越大；变化后的子屏间的夹角越小，则调整后的饱和度越小。再比如，子屏间的夹角增大，则调整后的饱和度增大(即饱和度的调整方向为增大)；子屏间的夹角减小，则调整后的饱和度减小(即饱和度的调整方向为减小)。用户针对控件1302的滑动操作可以调整对比度。比如，用户针对控件1302向左滑动，则调小对比度(即对比度的调整方向为减小)；用户针对控件1302向右滑动，则调大对比度(即对比度的调整方向为增大)。即，对比度的调整与用户针对控件1302的滑动方向和滑动幅度相关联。
如图13A中的(d)所示，当折叠屏设备在预设时长内检测到用户针对控件1302的滑动操作，并检测到子屏间的夹角发生变化时，可以根据子屏间的夹角变化调整饱和度，同时根据用户针对控件1302的滑动方向和滑动幅度调整对比度。对比图13A中的(d)与(c)可知，饱和度和对比度均发生了变化。
在一些实施例中，在折叠屏设备由第一状态折叠至第二状态，并触发执行预设操作后，若折叠屏设备恢复至第一状态，则折叠屏设备撤销该预设操作的执行，恢复到执行预设操作之前的状态。
示例性的，折叠屏设备处于第一状态，显示如图13B中的(a)所示的界面1。在满足上述预设条件后，折叠屏设备开启单手模式，并显示如图13B中的(b)所示的界面2。在用户翻转折叠屏以使得折叠屏设备恢复第一状态后，折叠屏设备撤销开启单手模式的操作，退出单手模式，并恢复显示如图13B中的(a)所示的界面1。
再示例性的，折叠屏设备处于第一状态，显示如图13C中的(a)所示的界面3。在满足上述预设条件后，折叠屏设备增大音量，并显示如图13C中的(b)所示的界面4。其中，界面4与界面3相比增加了与预设操作相关的音量调整控件。在用户翻转折叠屏以使得折叠屏设备恢复第一状态后，折叠屏设备撤销增大音量的操作，音量恢复至增大前的状态，并显示如图13C中的(c)所示的界面5。其中，界面5与界面4相比减少了与预设操作相关的音量调整控件；且随着游戏的进展，与界面3和界面4相比，界面5的内容发生了变化。
在另一些实施例中，在折叠屏设备由第一状态折叠至第二状态，并触发执行预设操作后，若折叠操作的幅度较大，子屏间夹角的变化较大；或者若折叠操作使得子屏间的夹角变小，且折叠操作后第一子屏和第二子屏之间的夹角较小；或者若折叠操作使得子屏间的夹角变大，且折叠操作后第一子屏和第二子屏之间的夹角较大，则折叠屏设备可以保持当 前的翻折状态。若折叠操作的幅度较小，子屏间夹角的变化较小；或者若折叠操作使得子屏间的夹角变小，且折叠操作后第一子屏和第二子屏之间的夹角较大；或者若折叠操作使得子屏间的夹角变大，且折叠操作后第一子屏和第二子屏之间的夹角较小，则折叠屏设备可以回弹至第一状态。也就是说，与折叠屏设备由第一状态折叠至第二状态的过程相反，折叠屏设备还可以向相反的方向翻折第一子屏和/或第二子屏，以使得折叠屏设备恢复至第一状态。
其中，若折叠操作的幅度较大，子屏间夹角的变化较大；或者若折叠操作使得子屏间的夹角变小，且折叠操作后第一子屏和第二子屏之间的夹角较小；或者若折叠操作使得子屏间的夹角变大，且折叠操作后第一子屏和第二子屏之间的夹角较大，则可以表明折叠程度较大，用户大力度地推动了折叠屏。用户可能确实想要在折叠操作后的第二状态下使用折叠屏设备，因而折叠屏设备可以保持当前折叠程度较大的第二状态不变。若若折叠操作的幅度较小，子屏间夹角的变化较小；或者若折叠操作使得子屏间的夹角变小，且折叠操作后第一子屏和第二子屏之间的夹角较大；或者若折叠操作使得子屏间的夹角变大，且折叠操作后第一子屏和第二子屏之间的夹角较小，则可以表明折叠程度较小，用户轻轻推动了折叠屏，用户可能只想触发预设操作，并不想在折叠操作后的第二状态下使用折叠屏设备。因而，折叠屏可以自动回弹至第一状态，在原第一状态下使用折叠屏，从而不会影响折叠屏显示界面的视角。
并且，在回弹后，折叠屏设备保持执行预设操作后的状态，折叠屏设备执行的预设操作，响应于预设操作显示的界面均不会撤销和回退。例如，若折叠触发的预设操作为向后翻页，则折叠屏回弹后，折叠屏设备仍然显示翻页后的页面，而不会显示翻页前的页面。再例如，若折叠触发的预设操作为单手模式，则折叠屏回弹后，折叠屏设备仍然处于单手模式，而并不会退出单手模式。
以下实施例以预设操作为开启单手模式为例来举例说明。
示例性的，如图14中的(a)所示，用户正常使用折叠屏设备时，折叠屏设备通常处于展开状态。折叠屏设备由展开状态折叠至如图14中的(b)或(d)所示的状态1。在满足上述预设条件(即预设条件1、预设条件2或预设条件3)后，折叠屏设备触发开启单手模式。在单手模式下，如图14中的(b)或(d)所示，界面显示范围缩小。
若由展开状态折叠至如图14中的(b)所示的状态1的过程中，第一子屏和第二子屏之间的夹角变小了δ1，且δ1小于或者等于预设角度1(例如为20°)，则可以表明用户轻轻推动了折叠屏。或者，若由展开状态折叠至如图14中的(b)所示的状态1的后，第一子屏和第二子屏之间的夹角由180°减小为角度1，且角度1大于预设角度2(例如为160°)，则可以表明用户轻轻推动了折叠屏。用户可能只想开启单手模式，并不想在折叠后的状态1下使用折叠屏设备。因而，参见图14中的(c)，折叠屏设备可以基于上述机械转轴和/或电子转轴，回弹至展开状态。此时，回弹后，第一子屏和第二子屏之间的夹角，由角度1恢复为展开状态时的180°。并且，如图14中的(c)所示，界面显示范围仍为图14中的(b)所示的缩小后的范围，折叠屏设备仍处于单手模式，而并不退出单手模式。
若由展开状态折叠至如图14中的(d)所示的状态1的过程中，第一子屏和第二子屏之间的夹角变小了δ1，且δ1大于预设角度1，则可以表明用户大力度地推动了折叠屏。或者，若由展开状态折叠至如图14中的(d)所示的状态1的后，第一子屏和第二子屏之间 的夹角由180°减小为角度1，且角度1小于或者等于预设角度2，则可以表明用户大力度地推动了折叠屏。用户可能确实想要在折叠后的状态1下使用折叠屏设备。因而，折叠屏设备可以保持当前的状态1，不回弹至展开状态。
需要注意的是，图14中的(a)-(c)是以子屏间的夹角减小的幅度较小时，进行回弹为例进行说明的。类似的，当子屏间的夹角减小的幅度较小时，也进行回弹，此处不予赘述。
再示例性的，如图15中的(a)所示，折叠屏设备处于状态2。折叠屏设备由状态2折叠至如图15中的(b)或(d)所示的状态3。在满足上述预设条件后，折叠屏设备触发开启单手模式。在单手模式下，如图15中的(b)或(d)所示，界面显示范围缩小。
若由状态2折叠至如图15中的(b)所示的状态3的过程中，第一子屏和第二子屏之间的夹角由角度2减小为角度3，该夹角变小了δ2，且δ2小于或者等于预设角度1，则可以表明用户轻轻推动了折叠屏。用户可能只想开启单手模式，并不想在折叠后的状态3下使用折叠屏设备。
因而，在一些实施例中，如图15中的(c)所示，折叠屏设备可以基于上述电子转轴，回弹至状态2。在回弹后，第一子屏和第二子屏之间的夹角由角度3恢复至角度2。在另一些实施例中，折叠屏设备可以基于上述电子转轴，回弹至展开状态。在回弹后，第一子屏和第二子屏之间的夹角由角度3恢复为展开状态时的180°。并且，如图15中的(c)所示，界面显示范围仍为如15中的(b)所示的缩小后的范围，折叠屏设备仍处于单手模式，而并不退出单手模式。
若由状态2折叠至如图15中的(d)所示的状态3的过程中，第一子屏和第二子屏之间的夹角变小了δ2，且δ2大于预设角度1，则可以表明用户大力度地推动了折叠屏。用户可能确实想要在折叠后的状态3下使用折叠屏设备。因而，折叠屏设备可以保持当前的状态3，不回弹至状态2。
再示例性的，如图16中的(a)所示，折叠屏设备处于状态4。折叠屏设备由状态4展开至如图16中的(b)或(d)所示的状态6。在满足上述预设条件后，折叠屏设备触发开启单手模式。在单手模式下，如图16中的(b)或(d)所示，界面显示范围缩小。
若由状态5折叠至如图16中的(b)所示的状态6的过程中，第一子屏和第二子屏之间的夹角由角度4增大为角度5，该夹角增大了δ2，且δ2小于或者等于预设角度1；或者角度5小于或者等于预设角度3，则可以表明用户轻轻推动了折叠屏。用户可能只想开启单手模式，并不想在折叠后的状态6下使用折叠屏设备。
因而，在一些实施例中，如图16中的(c)所示，折叠屏设备可以基于上述电子转轴，回弹至状态5。在回弹后，第一子屏和第二子屏之间的夹角由角度5恢复至角度4。并且，如图16中的(c)所示，界面显示范围仍为图16中的(b)所示的缩小后的范围，折叠屏设备仍处于单手模式，而并不退出单手模式。
若由状态5折叠至如图16中的(d)所示的状态6的过程中，第一子屏和第二子屏之间的夹角增大了δ2，且δ2大于预设角度1，则可以表明用户大力度地推动了折叠屏。用户可能确实想要在折叠后的状态6下使用折叠屏设备。因而，折叠屏设备可以保持当前的状态6，不回弹至状态5。
以上是以折叠屏的上屏向前方翻折来触发执行预设操作，并回弹为例进行说明的。在 其他一些实施例中，参见图17A，折叠屏的下屏也可以向前方翻折来触发执行预设操作，并回弹。在用户握持折叠屏设备的场景下，用户的无名指和小指可以自然地位于下屏的背面，从而自然地推动下屏向前方翻折。
在其他一些实施例中，折叠屏的上屏或下屏可以向后方翻折来触发执行预设操作。在用户握持折叠屏设备的场景下，位于折叠屏前方的手指可以自然地推动上屏或下屏向后方翻折。示例性的，折叠屏的上屏向后方翻折的示意图的可以参见图17B；折叠屏的下屏向后方翻折的示意图的可以参见图17C。
当预设操作为开启分屏模式时，折叠屏设备可以在上边的子屏上显示一个应用的窗口，在下边的子屏上显示另一个应用的窗口。
此外，预设操作还可以为开启多窗口模式。在开启多窗口模式后，折叠屏设备上边的子屏可以显示一个窗口，下边的子屏可以显示另一个窗口。
在其他一些实施例中，预设操作还可以为开启小屏模式。示例性的，如图18中的(a)所示，折叠屏设备处于展开状态。折叠屏设备在预设时长内检测到子屏间的夹角发生变化(例如变小)，且检测到用户按压折叠屏的操作后，参见图18中的(b)，折叠屏设备开启小屏模式。如图18中的(b)所示，折叠屏设备在上边的子屏上显示界面。或者，折叠屏设备在下边的子屏上显示界面。或者，折叠屏设备在两个子屏分别显示界面。
在其他一些实施例中，用户还可以结合上述折叠操作以及针对摄像头的操作，来触发预设操作。尤其在双手握持的场景下，用户可以自然地通过上述折叠操作以及针对摄像头的操作，来触发预设操作。比如，预设操作可以为启动相机，或开启小屏模式并启动相机等。
例如，用户可以按住摄像头并对折叠屏进行折叠，来触发开启小屏模式并启动相机。摄像头附近可以是设置有触摸传感器，可以检测到用户是否按压摄像头位置。折叠屏设备在预设时长内检测到上述折叠操作以及摄像头被按压后，可以触发预设操作。
再例如，用户可以用手挡住摄像头并对折叠屏进行折叠，来触发开启小屏模式并启动相机。摄像头附近可以是设置有接近光传感器、红外传感器等，可以检测到用户是否遮挡摄像头。折叠屏设备在预设时长内检测到上述折叠操作以及摄像头被遮挡后，可以触发预设操作。
示例性的，预设操作为开启小屏模式并启动相机。如图19中的(a)所示，折叠屏设备处于展开状态。参见图19中的(b)，折叠屏设备检测到折叠屏发生折叠且摄像头被按压。参见图19中的(c)，折叠屏设备开启小屏模式并启动相机。在一些实施例中，类似于化妆盒的效果，如图19中的(c)所示，折叠屏设备可以在上边的子屏显示拍摄预览界面，在下边的子屏显示拍摄的相关参数。或者，折叠屏设备可以在上边的子屏显示拍摄的相关参数，在下边的子屏显示拍摄预览界面。在另一些实施例中，如图19中的(d)所示，折叠屏设备的两个子屏相当于两面镜子，折叠屏设备在两个子屏上分别显示拍摄预览界面。
以上是以折叠屏设备具有上、下两个子屏为例进行说明的，本申请实施例提供的基于折叠屏的交互方法，还可以应用于具有更多子屏数量和具有其他子屏分布结构的折叠屏设备。
例如，在一些施例中，如图3A所示的具有上、中、下三个子屏的折叠屏设备，也可以通过上屏，中屏，下屏，上屏和中屏，或中屏和下屏，向前方翻折来触发执行预设操作； 或者向后方翻折来触发执行预设操作。并且，折叠屏还可以在折叠幅度较小的情况下，回弹至折叠前的状态。
本申请的实施例所涉及的握持场景，可以是单手握持场景或双手握持场景。在其他一些实施例中，在用户双手握持折叠屏设备的场景下，如图4A所示的具有左、右两个子屏的折叠屏设备，也可以通过左屏或右屏向前方翻折来触发执行预设操作；或者向后方翻折来触发执行预设操作。并且，折叠屏还可以在折叠幅度较小的情况下，回弹至折叠前的状态。
以上实施例主要是结合折叠屏设备检测到用户的触控操作和折叠操作，来触发预设操作，且该折叠操作使得相邻子屏间的夹角减小，或使得相邻子屏间的夹角增大为例进行说明的。
在其他实施例中，折叠屏设备检测到的上述折叠操作，还可以替换为其他多种方式。例如，上述折叠操作可以替换为，用户对折叠屏进行折叠，相邻子屏之间的夹角变小后再变大(无需恢复为夹角变小前的状态)。示例性的，预设操作为单手模式，如图20中的(a)所示，折叠屏设备处于展开状态，子屏间的夹角为180°。参见图20中的(b)，用户对折叠屏进行折叠后，折叠屏设备检测到子屏间的夹角由180°变小了γ1；而后，参见图20中的(c)，用户推动子屏，折叠屏设备检测到子屏间的夹角又变大了γ2。γ2与γ1可以相等，也可以不等。从而，折叠屏设备在预设时长内检测到子屏间的夹角变小后又变大；并且，结合折叠屏设备检测到用户针对折叠屏的触控操作，或者针对折叠屏设备侧边的按压操作，如图20中的(d)所示，折叠屏设备执行该预设操作，开启单手模式。
再例如，上述折叠操作可以替换为，用户对折叠屏进行折叠，相邻子屏间的夹角变小后，再恢复为夹角变小前的状态。
再例如，上述折叠操作可以替换为，用户对折叠屏进行折叠，相邻子屏之间的夹角变大后再变小。
再例如，上述折叠操作可以替换为，用户对折叠屏进行折叠，折叠屏向后折叠后，再向前折叠。示例性的，预设操作为单手模式。如图21中的(a)所示，折叠屏设备处于展开状态。参见图21中的(b)，折叠屏设备检测到用户将折叠屏向前折叠，此时子屏间的夹角为α1；而后，参见图21中的(c)，用户推动子屏，折叠屏设备检测到折叠屏向后折叠，此时子屏间的夹角为α2。从而，折叠屏设备在预设时长内检测到折叠屏向后折叠后又向前折叠；并且，结合折叠屏设备检测到用户针对折叠屏的触控操作，或者针对折叠屏设备侧边的按压操作，如图21中的(d)所示，折叠屏设备执行该预设操作，开启单手模式。
再例如，上述折叠操作可以替换为，用户对折叠屏进行折叠，折叠屏向后折叠后，再恢复向后折叠前的状态。
再例如，上述折叠操作可以替换为，用户对折叠屏进行折叠，折叠屏向前折叠后，再向后折叠。
再例如，上述折叠操作可以替换为，用户对折叠屏进行折叠，折叠屏向前折叠后，再恢复向前折叠前的状态。示例性的，预设操作为单手模式。如图22中的(a)所示，折叠屏设备处于展开状态。参见图22中的(b)，折叠屏设备检测到用户将折叠屏向前折叠；而后，参见图22中的(c)，用户推动子屏，折叠屏设备检测到折叠屏恢复为展开状态。从而，折叠屏设备在预设时长内检测到折叠屏向前折叠后，又恢复向前折叠前的状态；并且， 结合折叠屏设备检测到用户针对折叠屏的触控操作，或者针对折叠屏设备侧边的按压操作，如图22中的(c)所示，折叠屏设备执行该预设操作，开启单手模式。
再例如，当上述折叠操作为，用户对折叠屏进行折叠，折叠屏向前折叠后，再恢复向前折叠前的状态时；对应的预设操作为开启右手单手模式。当上述折叠操作为，用户对折叠屏进行折叠，折叠屏向后折叠后，再恢复向后折叠前的状态；且对应的预设操作为开启左手单手模式。
再例如，如图23中的(a)和(b)所示，上述折叠操作可以替换为，用户对折叠屏进行折叠，左边的子屏朝右边的子屏所在的位置进行折叠；对应的预设操作为开启右手单手模式。如图24中的(a)和(b)所示，上述折叠操作可以替换为，用户对折叠屏进行折叠，右边的子屏朝左边的子屏所在的位置进行折叠，对应的预设操作为开启左手单手模式。
在一些实施例中，与上述实施例中的回弹过程类似，在通过其他折叠操作触发预设操作后，折叠屏设备还可以自动回弹至折叠前的状态，以方便用户使用。
本申请另一实施例提供了一种基于折叠屏的交互方法，可以应用于具有折叠屏的电子设备，折叠屏包括第一子屏和第二子屏。参见图25，该方法可以包括：
2501、电子设备确定满足预设条件，该预设条件包括：在预设时长内，检测到用户针对电子设备的触控操作，且通过传感器检测到第一子屏和第二子屏之间的夹角发生了变化。

2502、电子设备执行预设操作，该预设操作包括调整第一功能和第二功能；折叠屏上的第一控件用于调整第一功能，折叠屏上的第二控件用于调整第二功能，第一功能与第一子屏和第二子屏之间的夹角变化相关联；触控操作为针对第二控件的滑动操作，第二功能与滑动操作的滑动方向和滑动幅度相关联。
2503、若第一子屏和第二子屏之间的夹角由第一夹角变化为第二夹角，且第一夹角和第二夹角之间的差值小于或者等于第二预设角度，则电子设备自动翻折第一子屏和/或第二子屏，以使得第一子屏和第二子屏之间的夹角由第二夹角恢复为第一夹角。
此外，电子设备还可以执行以上实施例描述的折叠屏设备的步骤和操作，从而实现以上实施例提供的基于折叠屏的交互方法。
在用户握持电子设备的场景下，拇指通常会自然地位于电子设备附近。因而，用户可以在握持时自然地针对电子设备进行触控操作和折叠操作。也就是说，步骤2501-2503所示的方法可以在握持场景下，提供一种与折叠屏进行自然交互的方式，从而触发执行预设操作。该预设操作可以与触控操作的滑动方向、滑动幅度以及子屏间的夹角相关联。并且，在满足一定条件时，折叠屏还可以回弹至执行预设操作前的状态。
