Description

一种双面屏终端的屏幕切换方法及设备
本申请要求于2021年7月30日提交国家知识产权局、申请号为202110875382.2、申请名称为“一种双面屏终端的屏幕切换方法及设备”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
本申请实施例涉及触控技术领域，尤其涉及一种双面屏终端的屏幕切换方法及设备。
背景技术
随着当前终端触摸屏技术的突飞猛进，以及智能终端的普及和扩展，出现了双面屏终端。例如，双面屏终端包括正面触摸屏和背面触摸屏；又如，双面屏终端的触摸屏可以折叠成正反两个触摸屏，正反两个触摸屏展开后则形成一个较大的触摸屏。
通常，在用户使用双面屏终端的过程中，若双面屏终端检测到设备翻转，则双面屏终端进行屏幕切换。例如，假设手机包括图1所示A屏和B屏，其中A屏为当前工作屏幕，即A屏亮屏，B屏灭屏，当检测到设备翻转时，手机进行屏幕切换，将当前工作屏幕由A屏切换为B屏，即A屏灭屏，B屏亮屏。其中，在将当前工作屏幕由A屏切换为B屏之后，之前显示在A屏上的内容转移至B屏显示。
但是，在一些情况下，尽管设备翻转，但用户并不想切换当前工作屏幕。例如，假设用户正在使用图1所示手机的A屏，用户在打开二维码之后，将手机翻转以扫描二维码。在这种情况下，用户并不希望手机将当前工作屏幕由A屏切换为B屏。但是，若基于常规的翻转识别技术进行屏幕切换，对于上述情况，手机的A屏会灭屏，B屏会亮屏。

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。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
本申请实施例提供一种双面屏终端的屏幕切换方法，该方法应用于双面屏终端的设备翻转识别过程中。
示例性的，本申请实施例中的双面屏终端可以是具有双面屏幕的终端，所述双面屏终端的正反面可以分别设置有一个触摸屏，简称正反屏终端。其中，该正反屏终端包括两个触摸屏：第一屏和第二屏(如图1所示A屏和B屏)固定在终端机身的正反面。应理解，第一屏和第二屏的尺寸可以不同。例如，第一屏的面积可以占据整个A面，第二屏的面积占据B面的一部分(例如，占据一半)，B面同时还可以包括后盖。在一些实施例中，该正反屏终端可以是图1中的(a)所示手机 100，手机100包括A屏和B屏，A屏和B屏固定在手机100机身的正反面。其中，A屏是手机100的正面，B屏可以是手机100的反面；或者，A屏是手机100的反面，B屏可以是手机100的正面。假设图1中的(b)为图1中的(a)所示手机100的主视图，其示出了手机100的A屏；那么，图1中的(c)为图1中的(a)所示手机100的后视图，其示出了手机100的B屏。用户可以选择使用正反屏终端的两个屏幕之一进行显示。
或者，上述双面屏终端可以是折叠屏终端，如柔性折叠屏终端(例如，柔性折叠屏手机)和双屏折叠终端(例如，双屏折叠手机)。其中，折叠屏终端的触摸屏沿折叠边可以折叠成A屏和B屏，折叠后的终端的A屏和B屏朝外。折叠屏终端在折叠状态下，用户可以选择使用两个屏幕之一进行显示。
例如，如图2所示，为本申请实施例示出的一种柔性折叠屏手机200的形态示意图。其中，图2中的(a)是手机200沿折叠边折叠后的形态示意图。如图2中的(a)所示，手机200沿折叠边折叠后可以折叠成A屏(即第一屏)和B屏(即第二屏)。图2中的(b)是手机200沿折叠边展开(例如，半展开)的形态示意图。参考图2中的(b)，手机200沿折叠边展开后，A屏和B屏组成一个的触摸屏。其中，图2中的(a)和图2中的(b)所示黑色区域为手机200的触摸屏。

需要说明的是，上述正反屏终端与折叠屏终端的不同点在于：折叠屏终端的触摸屏可以沿折叠边折叠成A屏和B屏，A屏和B屏还可以合并成一个触摸屏；而正反屏终端的两个触摸屏的位置固定，不能合并成一个触摸屏。例如，如图2中的(a)所示折叠屏手机200或者图3中的(a)所示折叠屏手机300的A屏与B屏贴合的位置处存在折叠线；而图1中的(a)所示正反屏手机100的A屏与B屏是固定在一起的两个触摸屏，A屏与B屏贴合的位置处存在折叠线。
需要注意的是，当上述双面屏终端是折叠屏终端(如柔性折叠屏终端和双屏折叠终端)时，本申请实施例的方法应用于上述折叠屏终端处于折叠状态的情况。其中，本申请实施例中的折叠状态可以为图2中的(a)所示柔性折叠屏手机所处的状态，以及图3中的(a)所示双屏折叠手机所处的状态。
需要说明的是，本申请实施例提供的图1、图2和图3所示双面屏终端仅作为示例，本申请实施例并不限定双面屏终端的具体结构和形态。例如，本申请上述折叠屏终端可以是纵向折叠终端，还可以是横向折叠终端。

需要说明的是，图4所示手机包括的硬件模块只是示例性地描述，并不对手机的具体结构做出限定。例如，手机还可以包括其他功能模块。
可以理解，常规的双面屏终端在检测到设备翻转时，便会进行当前工作屏幕切换。示例性的，双面屏终端在其自身的运动传感器检测到设备发生预设翻转时，便会进行当前工作屏幕切换。例如预设翻转可以是面向用户的屏幕向背向用户的方向翻转，背向用户的屏幕向面向用户的方向翻转。但是，单纯基于运动传感器(如陀螺仪传感器)触发屏幕切换在实际使用中容易产生识别不准确的情况，即屏幕显示内容跳转至用户未使用的一侧屏幕。
例如，在扫码付款场景中，在手机的A屏面向用户显示图5A中的(a)所示付款二维码，B屏背向用户为灭屏状态时，用户希望在将设备翻转，使A屏在背向用户时仍然显示图5A中的(a)所示付款二维码(如图5A中的(b)所示)，以使机器扫描A屏上显示的付款二维码完成付款。但是，若单纯基于运动传感器检测设备的翻转来触发屏幕切换，则在将图5A中的(a)所示A屏翻转至背向用户时，此时B屏面向用户，A屏灭屏，付款二维码切换至B屏显示，则无法使机器成功扫描到付款二维码。
又如，在用户向其他人展示信息(如电子身份证，健康证明等)时，用户并不希望设备翻转触发屏幕切换。
为解决上述识别不准确的情况，本申请实施例提供一种双面屏终端的屏幕切换方法，该方法通过基于双面屏终端采集到的屏幕容值数据进行用户握持手势和/或用户握持位置识别，以判断当前正在被使用的屏幕，进而准确地进行当前工作屏幕判断。进一步的，在确定进行屏幕显示切换时，双面屏终端可以及时地进行屏幕显示切换。
示例性的，在本申请实施例中，屏幕容值数据可以由双面屏终端的触摸屏检测并采集。例如，双面屏终端的触摸屏可以是电容式触摸屏、电阻式触摸屏或者电感式触摸屏等。本申请以下实施例以双面屏终端的触摸屏是电容式触摸屏为例，以双面屏终 端采集到的触摸数据是屏幕容值数据为例，对本申请实施例提供的一种双面屏终端的屏幕切换方法进行具体介绍。
其中，电容式触摸屏包括横向和纵向的电极阵列，该横向和纵向的电极阵列构成在屏幕表面均匀分布的若干个测试点。例如，上述电极阵列可以由氧化铟锡(indium tin oxide，ITO)制成。由于相邻电极之间可以产生自电容，所以通过自电容扫描方式采集各个测试点的自电容值的变化，可以实现对单点触摸的检测。另外，由于相邻电极之间也可以产生互电容，所以通过互电容扫描方式采集各个测试点的互电容值的变化，也可以实现对多点触摸的检测。
示例性的，在一些实施例中，双面屏终端可以基于屏幕容值Diff数据进行用户握持手势和/或用户握持位置识别。在另一些实施例中，双面屏终端可以基于多份屏幕原始容值数据进行用户握持手势和/或用户握持位置更改或变化的识别。
以下将结合附图，对本申请实施例提供的一种双面屏终端的屏幕切换方法进行具体介绍，以下实施例中的方法均可以在具有上述硬件结构的手机400(例如正反屏手机100、柔性折叠屏手机200、双屏折叠手机300)中实现。
实施例1：
在本申请实施例1中，双面屏终端基于屏幕容值Diff数据(即第一数据)进行用户握持手势和/或用户握持位置识别。
如图5B所示，本申请实施例提供的一种双面屏终端的屏幕切换方法可以包括以下步骤S501-S504：
S501、双面屏终端采集第一数据。
其中，第一数据用于表征触摸屏接受触摸时检测到的容值数据与预设门限值之间的差值。
可选的，预设门限值可以根据触摸屏未接受触摸时检测到的容值数据确定。
S502、双面屏终端基于第一数据进行用户握持手势和/或用户握持位置识别。
可以理解，在触摸屏未接受触摸时，由于外界干扰(例如温度、湿度等因素的影响)的存在，该若干个测试点仍然会检测到电容值。因此，本申请实施例1基于第一数据，在排除温度、湿度等外界干扰的情况下，可以直接反应触控感应量。以根据触控感应量和位置对用户握持位置进行确定，进而准确、及时地进行当前工作屏幕判断。
其中，触控的位置用于反映触摸屏被用户握持的位置(即用户握持位置)，触控感应量用于反映触摸屏被用户握持时，用户手部与触摸屏的接触紧密程度和接触紧密程度的面积分布。
示例性的，图6以图2所示柔性折叠屏手机200为例，示出了一种触摸屏未接受触摸时检测到的第一数据示例图。其中，图6为柔性折叠屏手机200的触摸屏(包括A屏和B屏)未接受触摸时检测到的第一数据。图6所示ab边即图2所示A屏的ab边，图6所示cd边即图2所示B屏的cd边，图6所示ef即图2所示折叠边ef。
如图6所示，触摸屏(包括A屏和B屏)包括横向和纵向的电极阵列构成的屏幕表面均匀分布的若干个测试点。在触摸屏未接受触摸时，由于外界干扰(例如温度、湿度等因素的影响)的存在，该若干个测试点分别检测到图6所示第一数据。
可选的，在本申请实施例中，触摸屏终端未接受触摸时检测到的容值数据可以预 先储存在触摸屏终端中，例如可以以上述预设门限值的形式在触摸屏终端出厂前预先设置在触摸屏终端中。
可选的，在本申请实施例中，在触摸屏终端被使用的过程中，根据触摸屏终端未接受触摸时检测到的容值数据确定的上述预设门限值还可以更新。例如可以周期性更新。又如可以根据当前实时环境进行实时更新，如在每次开机时等时机根据当前实时环境进行实时更新。
可选的，在本申请实施例中，上述预设门限值还可以从其他装置或***处获取，本申请实施例对于上述预设门限值的具体设置依据、规则和方式等不做限定。
示例性的，图7中的(a)以图2所示柔性折叠屏手机200被用户以图7中的(b)所示握持手势握持为例，示出了一种触摸屏被握持时检测到的第一数据示例图。图7中的(a)为柔性折叠屏手机200的触摸屏(包括A屏和B屏)被握持时检测到的第一数据。其中，图7中的(a)所示ab边即图2和图7中的(b)所示A屏的ab边，图7中的(a)所示cd边即图2所示B屏的cd边，图7中的(a)所示ef即图2和图7中的(b)所示折叠边ef。如图7中的(a)所示，触摸屏(包括A屏和B屏)包括横向和纵向的电极阵列构成的屏幕表面均匀分布的若干个测试点。其中，上述若干个测试点分别检测到图7中的(a)所示第一数据。
其中，在图6所示示例图和图7中的(a)所示示例图中，数值越大，则代表对应位置的接触越紧密；数值越小，则代表对应位置的接触越轻。
在一些实施例中，双面屏终端可以基于检测到的第一数据，结合预先设置的阈值进行用户握持位置确定。
示例性的，双面屏终端可以通过比较检测到的第一数据与预先设置的阈值之间的大小关系，来判定是否发生触控事件。例如，若数值大于(＞)(或者“≥”)预先设置的阈值，则判定发生触控事件；若数值小于(＜)(或者“≤”)预先设置的阈值，则判定未发生触控事件。其中，发生触控事件的位置即用户握持位置。
示例性的，上述预先设置的阈值可以为200-500中任一常数。
例如，假设预先设置的阈值为300，在触摸屏被用户以图7中的(b)所示握持手势握持时，如图7中的(a)所示，a71、a72、a73和a74四个区域的测试点检测到的数值大于预先设置的阈值300，则可以判定a71、a72、a73和a74四个区域发生触控事件。对比图7中的(b)所示握持手势，可以确定发生触控事件的a71、a72、a73和a74四个区域分别对应图7中的(b)所示手指71、手指72、手指73和手指74与触摸屏的接触区域。
由于外界干扰(例如温度、湿度等因素的影响)的存在，除a71、a72、a73和a74以外的其他区域的测试点也检测到第一数据，但是数值很小，因此可以判定该区域未发生触控事件。对比图7中的(b)所示握持手势，可以确定除手指71、手指72、手指73和手指74以外，用户手掌的其他区域未与双面屏终端的触摸屏发生接触。图7中的(b)所示手指75虽然与双面屏终端接触，但是由于其具体是与双面屏终端的侧边框接触的，而侧边框上未设置有压力检测单元(例如电极阵列构成的测试点)，因此手指75与双面屏终端的接触区域未检测到第一数据，因而也未检测到触控事件。
又如，假设预先设置的阈值为300，在触摸屏被用户以图8中的(b)所示握持手 势握持时，如图8中的(a)所示，a81和a82两个区域的测试点检测到的数值大于预先设置的阈值300，则可以判定a81和a82两个区域发生触控事件。对比图8中的(b)所示握持手势，可以确定发生触控事件的a81和a82两个区域分别对应图8中的(b)所示手指81和虎口82与触摸屏的接触区域。
由于外界干扰(例如温度、湿度等因素的影响)的存在，除a81和a82以外的其他区域的测试点也检测到第一数据，但是数值很小，因此可以判定该区域未发生触控事件。对比图8中的(b)所示握持手势，可以确定除手指81和虎口82以外，用户手掌的其他区域未与双面屏终端的触摸屏发生接触。其中，图8中的(b)所示手指83和手指84虽然与双面屏终端接触，但是由于其具体是与双面屏终端的侧边框接触的，而侧边框上未设置有压力检测单元(例如电极阵列构成的测试点)，因此手指83和手指84与双面屏终端的接触区域未检测到第一数据，因而也未检测到触控事件。
需要说明的是，图7中的(b)和图8中的(b)所示双面屏终端的侧边框中未设置有压力检测单元(例如电极阵列构成的测试点)，因此在图7中的(b)所示手指75接触双面屏终端的区域，图8中的(b)所示手指83和手指84接触双面屏终端的区域，双面屏终端未检测到第一数据。但是，由于双面屏终端的触摸屏上设置有压力检测单元，因此尽管触摸屏折叠形成图7中的(b)和图8中的(b)所示折叠边，该折叠边位置仍然可以检测到第一数据。
进一步的，在一些实施例中，在确定用户握持位置之后，双面屏终端还可以结合用户握持位置对应的第一数据进行用户握持手势模拟。
例如，双面屏终端可以通过神经网络(例如卷积神经网络)对大量的握持手势和对应第一数据进行训练学习，建立握持手势模型。在本申请实施例中，双面屏终端可以根据用户握持位置对应的第一数据对用户握持位置的中心、重心等信息进行分析，并进一步基于建立的握持手势模型进行用户握持手势模拟，以根据模拟的用户握持手势判断当前正在被使用的屏幕，进而准确地进行当前工作屏幕判断。示例性的，第一数据最大的握持区域为用户握持重心区域，则该重心区域为用户手部与双面屏终端接触最紧密的区域。
进一步的，在确定需要进行屏幕显示切换时，双面屏终端可以及时地进行屏幕显示切换。例如，在确定当前的工作屏幕发生变化(例如，由A屏变为B屏，或者由B屏变为A屏)，则双面屏终端进行屏幕显示切换。
例如，在本申请一些实施例中，在第一时刻，工作屏幕为第一屏，在第二时刻，若双面屏终端根据第一数据确定用户在第一屏上的握持区域大于在第二屏上的握持区域，则双面屏终端确定工作屏幕是第二屏。对于这种情况，双面屏终端将工作屏幕由第一屏切换为第二屏。
又如，在第一时刻，工作屏幕为第一屏，在第二时刻，在双面屏终端根据第一数据确定用户在第一屏上的握持区域大于第一阈值，且用户在第二屏上的握持区域小于第二阈值，则双面屏终端确定工作屏幕是第二屏。对于这种情况，双面屏终端将工作屏幕由第一屏切换为第二屏。
需要说明的是，本申请实施例仅以双面屏终端在一个时刻(例如，第二时刻)采集第一数据作为示例，本申请实施例对用于确定用户握持位置所基于的第一数据数量 不做限定。例如，双面屏终端还可以基于在多个时刻连续采集的多份第一数据的平均值进行用户握持位置识别。又如，双面屏终端还可以基于多份第一数据的变化进行用户握持位置识别。
另外，本申请对于用户握持手势模拟的具体方法、算法以及模型等不做限定。上述神经网络(例如卷积神经网络)仅作为一种深度学习方法及算法示例。
S503、双面屏终端分析用户握持手势和/或用户握持位置，判断当前正在被使用的屏幕(当前工作屏幕)。
可以理解，根据用户的使用习惯，在双面屏终端的某一侧屏幕被使用时，用户的握持手势倾向于不遮挡该侧屏幕大面积显示内容，以便阅读或使用。
例如，根据用户的使用习惯，当用户想要使用图7中的(b)所示双面屏终端的A屏时，用户通常会以图7中的(b)所示握持手势握持双面屏终端。如图7中的(b)所示，用户的握持手势遮挡了B屏的大部分屏幕，但是几乎未遮挡A屏。又如，当用户想要使用图8中的(b)所示双面屏终端的B屏时，用户通常会以图8中的(b)所示握持手势握持双面屏终端。如图8中的(b)所示，用户的握持手势遮挡了A屏的大部分屏幕，但是几乎未遮挡B屏。
根据这个规律，本申请实施例提供的双面屏终端的屏幕切换方法通过对用户握持手势和/或用户握持位置的识别，可以准确判断当前正在使用的屏幕，以在需要进行屏幕显示切换时，准确、及时的进行屏幕显示切换。其中，若当前正在被使用的屏幕发生变化，则双面屏终端执行以下步骤S504：
S504、双面屏终端进行屏幕显示切换。
例如，双面屏终端通过对检测到的图7中的(a)所示第一数据进行分析，可以识别用户握持位置包括图7中的(a)所示a71、a72、a73和a74四个区域。进一步的，双面屏终端通过分析a71、a72、a73和a74四个区域与双面屏终端触摸屏的具体对应关系，预测用户当前想要使用图7中的(b)所示A屏。基于该结论，若当前工作屏幕是B屏，则双面屏终端将当前工作屏幕由B屏切换为A屏。
又如，双面屏终端通过对检测到的图8中的(a)所示第一数据进行分析，可以识别用户握持位置包括图8中的(a)所示a81和a82四个区域。进一步的，双面屏终端通过分析a81和a82两个区域与双面屏终端触摸屏的具体对应关系，预测用户当前想要使用图8中的(b)所示B屏。基于该结论，若当前工作屏幕是A屏，则双面屏终端将当前工作屏幕由A屏切换为B屏。
又如，在例如图5A所示扫码付款场景或者用户翻转手机以向其他人展示信息(如电子身份证，健康证明等)等场景下，采用本申请实施例提供的双面屏终端的屏幕切换方法，即使运动传感器(如陀螺仪传感器)检测到设备发生预设翻转，终端也不会进行工作屏幕显示切换。基于该方案，用户可以在类似上述场景中得到很好的使用体验。
其中，在本申请实施例中，预设翻转可以以预设空间姿态变化的形式预先设置在双面屏终端中。示例性的，预设空间姿态变化可以基于对终端翻转大数据的训练和分析，确定并预先设置在双面屏终端中。
可以理解，上述实施例1中的第一数据用于表征触摸屏接受触摸时检测到的容值 数据与预设门限值之间的差值。我们知道，在触摸屏未接受触摸时检测到的容值数据是受外界环境如设备是否上电、温度、湿度等因素影响的，因此对于预设门限值根据触摸屏未接受触摸时检测到的容值数据确定的情况，双面屏终端无法获得一个合理有效的预设门限值，因此也无法获得合理有效的第一数据。
为解决上述由于设备是否上电、温度、湿度等外界环境的影响造成的第一数据缺乏合理性和有效性的问题，本申请实施例提供了以下实施例2。
实施例2：
在本申请实施例2中，双面屏终端基于多个时刻对应的屏幕Raw容值数据(如第二数据和第三数据)进行用户握持手势和/或用户握持位置更改或变化的识别。
其中，屏幕Raw容值数据(以下简称“Raw数据”)用于表征触摸屏接受触摸时检测到的原始容值数据。上述第二数据是双面屏终端在第一时刻采集的触摸屏接受触摸时检测到的原始容值数据，上述第三数据是双面屏终端在第二时刻采集的触摸屏接受触摸时检测到的原始容值数据。
示例性的，以下实施例以双面屏终端基于两份屏幕Raw容值数据的差值识别用户握持手势和/或用户握持位置的更改或变化为例，对本申请实施例提供的一种双面屏终端的屏幕切换方法进行介绍。
例如，当本申请实施例提供的方法算法启动时(即第一时刻)，可以采集第二数据；以及，在一段时间之后(即第二时刻)，采集第三数据。其中，上述一段时间可以是预设时长(例如5秒)，或者上述一段时间之后可以由某一事件触发(例如检测到预设翻转等)，本申请不限定。
如图9A所示，本申请实施例提供的一种双面屏终端的屏幕切换方法可以包括以下步骤S901-S905：
S901、双面屏终端采集第二数据。
示例性的，图9B中的(a)以图2所示柔性折叠屏手机200被用户以图9B中的(b)和图9B中的(c)所示握持手势握持为例，示出了一种触摸屏被握持时检测到的第一数据示例图。
其中，图9B中的(a)为柔性折叠屏手机200的触摸屏(包括A屏和B屏)被用户以图9B中的(b)和图9B中的(c)所示握持手势握持时检测到的第二数据。其中，图9B中的(b)示出了用户握持终端时A屏一面的握持状态，图9B中的(c)示出了用户握持终端时B屏一面的握持状态。
图9B中的(a)所示ab边即图2和图9B中的(b)所示A屏的ab边，图9B中的(a)所示cd边即图2和图9B中的(c)所示B屏的cd边(其中图9B中的(c)所示cd边部分被用户手掌遮挡)，图9B中的(a)所示ef即图2、图9B中的(b)和图9B中的(c)所示折叠边ef(其中图9B中的(c)所示折叠边ef部分被用户手掌遮挡)。如图9B中的(a)所示，触摸屏(包括A屏和B屏)表面均匀分布的若干个测试点分别检测到图9B中的(a)所示原始容值。
S902、伴随双面屏终端的翻转，双面屏终端采集第三数据。
示例性的，图10中的(a)以图2所示柔性折叠屏手机200被用户以图10中的(b)和图10中的(c)所示握持手势握持为例，示出了一种触摸屏被握持时检测到的第三 数据示例图。
其中，图10中的(a)为柔性折叠屏手机200的触摸屏(包括A屏和B屏)被用户以图10中的(b)和图10中的(c)所示握持手势握持时检测到的第三数据。其中，图10中的(b)示出了用户握持终端时B屏一面的握持状态，图10中的(c)示出了用户握持终端时A屏一面的握持状态。
图10中的(a)所示ab边即图2和图10中的(c)所示A屏的ab边(其中图10中的(c)所示ab边部分被用户手掌遮挡)，图10中的(a)所示cd边即图2和图10中的(b)所示B屏的cd边，图10中的(a)所示ef即图2、图10中的(b)和图10中的(c)所示折叠边ef(其中图9B中的(c)所示折叠边ef部分被用户手掌遮挡)。如图10中的(a)所示，触摸屏(包括A屏和B屏)表面均匀分布的若干个测试点分别检测到图10中的(a)所示原始容值。
S903、双面屏终端基于第二数据和第三数据的差值进行用户握持手势和/或用户握持位置更改或变化的识别。
示例性的，假设用户握持双面屏终端由图9B中的(b)和图9B中的(c)所示握持状态，翻转至图10中的(b)和图10中的(c)所示握持状态，则在本申请实施例中，双面屏终端可以通过分析图10中的(a)所示第三数据和图9B中的(a)所示第二数据的差值，进行用户握持手势和/或用户握持位置更改或变化的识别。
如图9B中的(a)所示，双面屏终端可以识别用户以图9B中的(b)和图9B中的(c)所示握持手势握持终端时，握持位置包括图9B中的(a)所示a91和a92两个区域。其中，a91与用户的大拇指接触，a92与用户的手掌和食指接触。如图10中的(a)所示，双面屏终端可以识别用户以图10中的(b)和图10中的(c)所示握持手势握持终端时，握持位置包括图10中的(a)所示a101、a102、a103、a104和a105两个区域。其中，a101与用户的虎口接触，a102、a103、a104和a105分别与用户的食指、中指、无名指和小拇指接触。
基于图9B中的(a)所示Raw数据1和图10中的(a)所示Raw数据2，双面屏终端得到图11所示Raw数据差值。其中，从图11可以看出双面屏终端被用户由图9B中的(b)和图9B中的(c)所示握持状态，翻转至图10中的(b)和图10中的(c)所示握持状态之后，新增的握持位置区域和消失的握持位置区域。
如图11所示，双面屏终端被用户由图9B中的(b)和图9B中的(c)所示握持状态，翻转至图10中的(b)和图10中的(c)所示握持状态之后，握持位置区域由之前的集中在B屏变化为集中A屏。
S904、双面屏终端分析用户握持手势和/或用户握持位置的更改或变化，判断当前正在被使用的屏幕(当前工作屏幕)。
可以理解，根据用户的使用习惯，在双面屏终端的某一侧屏幕被使用时，用户的握持手势倾向于不遮挡该侧屏幕大面积显示内容，以便阅读或使用。因此，根据这个规律，对于图11所示原始容值数据的变化，双面屏终端可以预测用户当前想要从A屏显示切换为B屏显示，则双面屏终端将当前工作屏幕由A屏切换为B屏。
进一步的，在一些实施例中，在确定用户握持位置之后，双面屏终端还可以结合用户握持位置对应的原始容值数据进行用户握持手势模拟，以根据模拟的用户握持手 势判断当前正在被使用的屏幕，进而准确地进行当前工作屏幕判断。进一步的，在确定进行屏幕显示切换时，双面屏终端可以及时地进行屏幕显示切换。例如，在确定当前工作屏幕发生变化(例如，由A屏切换为B屏，或者由B屏切换为A屏)，则双面屏终端执行以下步骤S905，进行屏幕显示切换。
S905、双面屏终端进行屏幕显示切换。
例如，在本申请一些实施例中，若双面屏终端根据原始容值数据确定用户在第一屏上的握持区域大于在第二屏上的握持区域，则双面屏终端确定工作屏幕是第二屏。对于这种情况，双面屏终端将工作屏幕由第一屏切换为第二屏。
又如，在双面屏终端根据原始容值数据确定用户在第一屏上的握持区域大于第一阈值，且用户在第二屏上的握持区域小于第二阈值，则双面屏终端确定工作屏幕是第二屏。对于这种情况，双面屏终端将工作屏幕由第一屏切换为第二屏。
示例性的，双面屏终端可以通过神经网络(例如卷积神经网络)对大量的握持手势和对应原始容值数据进行训练学习，建立握持手势模型。关于这部分内容，可以参考实施例1中的介绍，这里不做赘述。
需要说明的是，本申请图7、图8、图9B和图10仅作为几种握持位置和握持手势示例，本申请实施例对用户握持双面屏终端的具体握持位置和握持手势不做限定。例如，握持手势还可以是双手同时握持等。
在一些实施例中，为了更加可靠地进行当前正在被使用的屏幕的判断，本申请实施例提供的双面屏终端的屏幕切换方法还可以在运动传感器(如陀螺仪传感器)识别预设翻转的基础上进行。例如，本申请实施例提供的例如上述实施例1和实施例2所介绍的识别用户握持位置和/或用户握持手势，进而进行屏幕切换的方法可以在运动传感器识别到预设翻转时进行。
请参考图12，图12以识别预设翻转后结合本申请实施例1提供的方法进行屏幕切换为例，示出了本申请实施例提供的一种双面屏终端的屏幕切换方法流程图。如图12所示，本申请实施例提供的一种双面屏终端的屏幕切换方法可以包括以下步骤S1201-S1202，以及上述步骤S501-S504：
S1201、双面屏终端获取运动数据。
其中，运动数据可以包括但不限于双面屏终端的运动方向、运动速度和运动角速度等。示例性的，双面屏终端可以通过运动传感器获取运动数据。
以运动传感器是陀螺仪传感器为例，示例性的，陀螺仪传感器可以通过对双面屏终端空间姿态的变化进行检测，以根据空间姿态的预设变化确定双面屏终端发生预设翻转。
例如，陀螺仪传感器可以通过持续记录三维空间内的翻转角度等空间姿态数值，用以持续检测双面屏终端在空间内的翻转。
作为一种示例，在本申请实施例中，当双面屏终端处于静止状态时，例如运动传感器(如陀螺仪传感器)检测到在三维空间内的翻转角度与加速度均为0时，运动传感器(如陀螺仪传感器)不对双面屏终端空间姿态的变化进行检测。当双面屏终端处于翻转状态时，例如运动传感器(如陀螺仪传感器)检测到在三维空间内的翻转角度和/或加速度时，运动传感器(如陀螺仪传感器)持续记录在三维空间内各方向的翻转 角度与加速度，直至双面屏终端重新恢复到静止状态。例如，双面屏终端的空间姿态可以用双面屏终端相对于地面坐标系的欧拉角(包括俯仰角(pitch)θ、偏航角(yaw)
Figure PCTCN2022108995-appb-000001
和横滚角(roll)φ)来表示。关于俯仰角、偏航角和横滚角的具体介绍，可以参考常规技术中的解释和说明，本申请实施例不做赘述。
S1202、双面屏终端根据运动数据识别其自身开始发生预设翻转。
以运动传感器是陀螺仪传感器为例，示例性的，双面屏终端可以基于陀螺仪传感器检测到的一段时间内，相应空间姿态数值(如翻转角度等)的变化，进行终端设备的翻转识别。例如，在识别到双面屏终端的翻转方向满足预设方向，翻转角度符合预设角度阈值时，双面屏终端可以确定其自身开始发生预设翻转。
S501、双面屏终端采集第一数据(如Diff数据)。
S502、双面屏终端基于第一数据进行用户握持手势和/或用户握持位置识别。
S503、双面屏终端分析用户握持手势和/或用户握持位置，判断当前正在被使用的屏幕(当前工作屏幕)。
若当前正在被使用的屏幕发生变化，则双面屏终端执行以下步骤S504：
S504、双面屏终端进行屏幕显示切换。
在一些实施例中，双面屏终端可以在其进行预设翻转的过程中，基于第一数据进行用户握持手势和/或用户握持位置识别，进而进行当前正在被使用的屏幕的判断以及屏幕显示的切换。
在另一些实施例中，双面屏终端还可以在其进行预设翻转的过程中，基于第一数据进行用户握持手势和/或用户握持位置识别，以及进行当前正在被使用的屏幕的判断。进一步的，如图13所示，在确定结束预设翻转时，双面屏终端进行屏幕显示的切换。示例性的，双面屏终端可以基于采集到的运动数据识别预设翻转结束。
关于图12和图13所示第一数据的采集、基于第一数据进行用户握持手势和/或用户握持位置识别、用户握持手势和/或用户握持位置分析、当前正在被使用的屏幕的判断等过程，可以参考上述实施例1中的介绍，这里不做赘述。
请参考图14，图14以识别预设翻转后结合本申请实施例2提供的方法进行屏幕切换为例，示出了本申请实施例提供的一种双面屏终端的屏幕切换方法流程图。如图14所示，本申请实施例提供的一种双面屏终端的屏幕切换方法可以包括上述步骤S1201-S1202，以及上述步骤S901-S905：
S901、双面屏终端采集第二数据。
S902、伴随双面屏终端的翻转，双面屏终端采集第三数据。
S903、双面屏终端基于第二数据和第三数据的差值进行用户握持手势和/或用户握持位置更改或变化的识别。
S904、双面屏终端分析用户握持手势和/或用户握持位置的更改或变化，判断当前正在被使用的屏幕。
若当前正在被使用的屏幕发生变化，则双面屏终端执行以下步骤S905：
S905、双面屏终端进行屏幕显示切换。
在一些实施例中，双面屏终端可以在其进行预设翻转的过程中，基于第二数据和第三数据的差值进行用户握持手势和/或用户握持位置更改或变化的识别，进而进行当 前正在被使用的屏幕的判断以及屏幕显示的切换。
在另一些实施例中，如图15所示，双面屏终端还可以在其进行预设翻转的过程中采集第二数据，以及在确定结束预设翻转时采集第三数据。然后，双面屏终端基于第二数据和第三数据的差值进行用户握持手势和/或用户握持位置更改或变化的识别，进而进行当前正在被使用的屏幕的判断以及屏幕显示的切换。示例性的，双面屏终端可以基于采集到的运动数据识别预设翻转结束。
关于图14和图15所示原始容值数据的采集、基于第二数据和第三数据的差值进行用户握持手势和/或用户握持位置更改或变化的识别、用户握持手势和/或用户握持位置的更改或变化的分析、当前正在被使用的屏幕的判断等过程，可以参考上述实施例2中的介绍，这里不做赘述。
需要说明的是，本申请实施例提供的方法中的具体算法，例如Raw数据或Diff数据分析算法、用户握持手势和/或用户握持位置分析算法可以由双面屏终端的任意一层软件结构来实现。以包括分层架构的Android***的双面屏终端为例，本申请实施例提供的方法中的具体算法可以设置在应用程序层，应用程序框架(framework，FWK)层，内核层(kernel)或硬件抽象层(hardware abstract layer，HAL)等层级中，本申请不限定。

本申请实施例可以对双面屏终端进行功能模块的划分，例如，可以对应各个功能划分各个功能模块，也可以将两个或两个以上的功能集成在一个处理模块中。上述集成的模块既可以采用硬件的形式实现，也可以采用软件功能模块的形式实现。需要说明的是，本申请实施例中对模块的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式。
