具体实施方式
下面将结合附图，对本申请实施例中的技术方案进行描述。
本申请实施例提供的防误触方法可应用于具有触摸屏的终端中。该终端例如可以为手机、平板电脑、多媒体播放设备、电子书阅读器、个人计算机、个人数字助理(personaldigitalassistant，PDA)、智能手表等。本申请对终端的具体形式不作限制。
本申请实施例的技术方案应用于终端处于背包或衣物(比如衣服、裤子等)口袋中的场景。在实际应用中，用户可将终端放置在衣服口袋、裤子口袋或背包中。为了便于描述，可以将“终端处于背包或衣物(比如衣服、裤子等)口袋中”的场景称作口袋模式。
可以理解，处于口袋模式的终端包括以下常见姿态：竖屏头朝上、竖屏头朝下、屏幕朝上、屏幕朝下、横屏竖起(可存在一定倾角)等。其中，竖屏头朝下是日常生活中终端放到口袋绝大多数状态。
还可以理解，本申请对用户的行为场景不作限定。比如，用户的行为场景包括但不限于以下行为：走、跑、坐、站立、躺、跳、骑等。
图1示出了本申请实施例的应用场景的一个示例图。如图1所示，该应用场景中，终端12放置在背包11中。当终端12放置在背包11中时，用户没有使用终端12的需求。终端12在背包11中时，可能会与背包11本身或背包11中包含的电容物质(金属导电物、皮肤等)接触，从而发生误触。
可以理解，图1中示出的背包11也可替换为衣物口袋，对此不作具体限定。
应理解，图1中的场景只是示意性说明本申请的一个应用场景，这并不对本申请实施例构成限定，本申请并不限于此。
当终端处于口袋模式时，与终端接触的物体可触发终端亮屏，导致终端误唤醒。这样的亮屏并非用户所期望的。若终端在口袋模式下长期处于亮屏状态，会严重浪费功耗。其中，与终端接触的物体包括但不限于以下内容：衣物口袋、背包、衣物口袋或背包中包含的电容物质(金属导电物、皮肤等)。
另外，在终端亮屏状态(该亮屏状态包括熄屏显示(always on display，AOD)亮起以及锁屏亮屏状态)下，与终端接触的物体可能会多次触发终端，从而发生多次误触，严重影响用户体验(比如，多次误触会触发指纹解锁功能锁死、密码输入误触多次会导致密码输入功能锁死、紧急呼叫功能被误触会误报警等)。
AOD是指不点亮整块屏幕的情况下，控制终端的屏幕局部亮起，将一些重要的信息显示在终端上。
本申请实施例提供的技术方案，通过多传感器协同检测终端的信息(包括但不限于环境光信息、第一信息、姿态角信息以及运动信息)，并根据终端的信息确定终端是否处于头朝下的口袋模式。如果确定终端是头朝下的口袋模式，那么在口袋模式下终端进入熄屏状态以节省功耗，并且，还能够避免终端在熄屏显示和锁屏亮屏状态下发生误唤醒，有效防止误触。

如图3所示，采用分层架构的软件系统分成若干个层，每一层都有清晰的角色和分工。层与层之间通过软件接口通信。在一些实施例中，软件系统可以分为四层，从上至下分别为应用程序层、应用程序框架层、安卓运行时(Android Runtime)和系统库、以及内核层。
应用程序层可以包括相机、图库、日历、通话、地图、导航、WLAN、蓝牙、音乐、视频、短信息等应用程序。

例如，应用程序框架层包括窗口管理器、内容提供器、视图系统、电话管理器、资源管理器和通知管理器。

视图系统包括可视控件，例如显示文字的控件和显示图片的控件。视图系统可用于构建应用程序。显示界面可以由一个或多个视图组成，例如，包括短信通知图标的显示界面，可以包括显示文字的视图以及显示图片的视图。
电话管理器用于提供电子设备100的通信功能，例如通话状态(接通或挂断)的管理。
资源管理器为应用程序提供各种资源，比如本地化字符串、图标、图片、布局文件和视频文件。
通知管理器使应用程序可以在状态栏中显示通知信息，可以用于传达告知类型的消息，可以短暂停留后自动消失，无需用户交互。比如通知管理器被用于下载完成告知和消息提醒。通知管理器还可以管理以图表或者滚动条文本形式出现在系统顶部状态栏的通知，例如后台运行的应用程序的通知。通知管理器还可以管理以对话窗口形式出现在屏幕上的通知，例如在状态栏提示文本信息、发出提示音、电子设备振动以及指示灯闪烁。
Android Runtime包括核心库和虚拟机。Android runtime负责安卓系统的调度和管理。
核心库包含两部分：一部分是java语言需要调用的功能函数，另一部分是安卓的核心 库。
应用程序层和应用程序框架层运行在虚拟机中。虚拟机将应用程序层和应用程序框架层的java文件执行为二进制文件。虚拟机用于执行对象生命周期的管理、堆栈管理、线程管理、安全和异常的管理、以及垃圾回收等功能。
系统库可以包括多个功能模块，例如：表面管理器(surface manager)，媒体库(Media Libraries)，三维图形处理库(例如：针对嵌入式系统的开放图形库(open graphics library for embedded systems，OpenGL ES)和2D图形引擎(例如：skia图形库(skia graphics library，SGL))。

将六轴融合姿态角算法模块设置于Sensorhub层的目的在于：Sensorhub层可以低功耗运行，这样，在不占用过多功耗的情况下可实时处理传感器数据。
以图4中所示的手机定义的坐标系统为例，假设手机屏幕朝上水平放置，x轴水平指向右边，Y轴垂直指向前方，Z轴指向正面正上方。当手机左右摇摆时(绕y轴旋转)，得到变化的滚转角；当手机前后摇摆时(绕x轴旋转)，得到变化的俯仰角；当手机横屏转换成竖屏或竖屏转换成横屏时(绕z轴旋转)，即得到变化的偏航角。

在利用四元数得到上述重力分量后，可以用来判断终端是头朝下，具体判断方法后文介绍。
以下结合图5-图9描述本申请实施例的防误触方法。
参考图5，图5示出了本申请实施例的防误触的方法的示意性流程图。可以理解，图5中的加速度传感器、陀螺仪传感器以及环境光传感器只是示例性描述，本申请并不限于此。可以理解，这些传感器也可以被具有相同功能的传感器替换。比如，环境光传感器可用于检测终端所处的环境光线，那么该环境光传感器可以被替换为用于检测终端所处的环境光线的传感器。该方法可应用于图1所示的场景。该方法包括：
S401，通过加速度传感器和陀螺仪传感器，获取终端的四元数，所述四元数用于表征所述终端的姿态。
具体地，获取终端的四元数通过以下方式实现：通过加速度传感器和陀螺仪各采集3轴数据，得到6轴数据，然后将该6轴数据输入到前文提到的六轴融合模块。六轴融合模块基于该6轴数据输出终端的四元数。
S402，基于所述终端的四元数，确定所述终端的第一信息以及姿态角信息。
所述姿态角信息用于标识所述终端的姿态。如前文所述，利用四元数可以计算终端的姿态角。在判断是否处于头朝下的口袋模式中，主要利用俯仰角。所述终端的姿态角信息包括终端的俯仰角。
其中，所述第一信息用于标识所述终端是否处于头朝下的状态。头朝下的状态是指终端的正向(正向是用户在竖屏使用时终端头部的方向)朝下的情况。在一些实施例中，头朝下的状态可以利用在正向朝下时的终端头朝下的角度是否在某个预设范围内，来判断终端是头朝下的状态。例如，在终端倒立放置在口袋中时，终端是头朝下的状态。
另外，如前文所述，利用四元数还可以计算重力分量v.x，v.y和v.z，其中，v.y和v.z可以作为判断终端头朝下的依据。所述终端的第一信息包括终端的重力分量v.y和v.z。
S403，通过加速度传感器检测所述终端的运动信息，所述运动信息用于标识所述终端的运动状态。
终端的运动状态包括以下两种状态：稳定状态以及运动状态。
稳定状态是指终端在一定时间段内保持相对平稳的状态。“终端一定时间段内保持相对平稳的状态”并非限定终端在该时间段内均未发生晃动，如果说终端在某个时间点虽然发生了轻微晃动，但在该时间段内整体保持平稳状态，这种情况下也认为是稳定状态。比如说，用户将手机放置在口袋中走路，终端有可能会发生轻微晃动，此时可以认为终端是稳定状态。
运动状态是指在用户使用终端的某些场景下，终端发生一定幅度的晃动或者摇动。比如说，用户在手持终端走路时，终端处于运动状态。
所述运动信息包括加速度计合速度值。通过比较终端的加速度计合速度值与合速度阈值可以判断终端的运动状态，后文将详细介绍。
S404，通过环境光传感器检测所述终端的环境光信息，所述环境光信息用于标识所述终端所处环境的光线强度(或光线亮度)。换种表述，所述环境光信息用于标识所述终端所处环境的光线强弱程度。光线强弱程度具体可通过光照度值来表征。比如，所述环境光信息包括终端所处环境的光照度，环境光照度值的单位可以采用lux。
举例来说，如果在白天用户手持终端使用的场景下，那么通过环境光传感器检测检测到终端所处环境的光照度值会比较大；如果终端在用户的衣服口袋中，那么通过环境光传感器检测检测到终端所处环境的光照度值会比较小。
S405，基于所述环境光信息、所述第一信息、所述姿态角信息以及所述运动信息，确定所述终端处于第一模式，所述第一模式用于标识所述终端的状态信息满足终端的相应预设条件。
其中，所述终端的状态信息包括终端在各个维度(包括：环境光线强度、终端所处的运动状态、终端的头朝下状态、终端的空间姿态等)的信息。在本申请实施例中，终端处于第一模式需要结合终端在各个维度的信息来判断。
例如，第一模式可以指头朝下的口袋模式。其中，头朝下的解释参见前文。
口袋模式的解释可参考下文：通常来讲，口袋模式是对用户在没有使用终端需求的情况下，将终端放置在某个弱光环境(甚至是不见光)下的一类场景的统称。比如说，用户在走路时，可以将终端放置在裤子口袋中或者背包中。又比如说，用户可以将终端放置在抽屉中等。结合上文关于头朝下状态的解释，例如，头朝下的口袋模式可以指终端被置于 某个弱光环境，且是头朝下的状态。应理解，口袋模式只是对上述一类场景的一个命名，此命名不对本申请实施例的保护范围构成限定。
所述终端处于头朝下的口袋模式包括以下条件：所述头朝下信息满足第一预设条件、所述姿态角信息满足第二预设条件、所述运动信息满足第三预设条件以及所述环境光信息满足第四预设条件。
在本申请实施例中，判断终端是否处于头朝下的口袋模式，要基于上述4种信息共同判断。在上述4种信息均满足预设条件的情况下，终端才能被判断为是处于头朝下的口袋模式。
可选地，所述头朝下信息满足第一预设条件，包括：(1)终端的第一重力分量(记作v.y)和第二重力分量(记作v.z)两轴的乘积为负数；(2)v.y的绝对值大于第一阈值，v.z的绝对值小于该第一阈值。第一阈值可以是5-10中的一个数值(包含端点值)。应理解，本申请对第一阈值的取值不作具体限定。比如，第一阈值可以是6，或者7，或者8等。在具体实现时，可以引入头朝下标识(headdown_flag)来标识终端是否是头朝下的状态。
可选地，所述姿态角信息满足第二预设条件，包括：终端的俯仰角在预设角度范围内。例如，预设角度范围是70度到130度。在具体实现时，可以引入俯仰角标识(pitch_flag)来标识终端的俯仰角是否在预设角度范围内。
可选地，所述运动信息满足第三预设条件，包括：连续n帧的加速度计合速度值小于或等于合速度阈值。例如，合速度阈值的取值可以为900-1300中的某个值。比如，合速度阈值取值为900、1000、1050或1100等。
可选地，所述运动信息满足第三预设条件还包括：所述连续n帧中第i帧的加速度计合速度值与第i-1帧的加速度计合速度值的差值小于预定差值阈值，其中，i∈[2,n]，n≥2。例如，假设n取值为5，i取值为4，对于连续5帧的加速度计合速度值，第4帧与第3帧的加速度计合速度值的差值小于预定差值阈值。预定差值阈值可以是100-180(包含端点值)中的某个值，本申请对此不作限定。比如，预定差值阈值可以取110、120、135、150或160等。在具体实现时，可以引入稳定状态标识(steady_flag)标识终端是处于运动状态还是口袋模式下的稳定状态。
可选地，所述环境光信息满足第四预设条件，包括：终端的环境光照度小于或等于第一光阈值。例如，第一光阈值可以设置为6.0lux，或者7.0lux等其他值，对此不作具体限定。
应理解，上述关于所述头朝下信息满足第一预设条件、所述姿态角信息满足第二预设条件、所述运动信息满足第三预设条件以及所述环境光信息满足第四预设条件的描述是示例性地描述，本申请不限于此。事实上，本领域技术人员可以为终端处于头朝下的口袋模式设定其他合理的判断条件。
S406，所述终端进入熄屏状态。熄屏状态是指终端的屏幕未发光的状态。
本申请实施例中，在终端接收到触发屏幕亮屏的信号(该信号可能是误触导致的)时，通过多传感器协同检测终端的环境光信息、第一信息、姿态角信息以及运动信息，并根据这些信息确定终端是否处于头朝下的口袋模式。如果确定终端是第一模式(或者说头朝下的口袋模式)，那么终端进入熄屏状态以节省功耗，并且，还能够避免终端在熄屏显示和 锁屏亮屏状态下发生误唤醒，有效防止误触。
为便于理解，以下结合图6中所示的流程详细描述各个信息的判断逻辑。如图6所示，包括：
501，通过环境光传感器检测终端的环境光是否大于第二光阈值。
如果检测到终端的环境光大于第二光阈值，则AOD亮起；如果否，则跳至510，判断终端的环境光是否大于第一光阈值(即前文S406处提到的第一光阈值)。
502，通过加速度传感器，获取当前帧的加速度计合速度值。
通过当前帧的加速度计合速度值，可以判断当前帧是否是相对稳定状态。
基于当前帧的加速度计合速度值，当前帧的相对稳定状态可通过以下条件(1)进行判断：当前帧的加速度计合速度值是否大于合速度阈值。如果当前帧的加速度计合速度值不大于合速度阈值，则可以认为终端在当前帧是相对稳定状态；如果当前帧的加速度计合速度值大于合速度阈值，则可以认为终端在当前帧不是相对稳定状态。
加速度计合速度值可记作a，a采用以下公式表示：a＝x 2+y 2+z 2，其中，x,y,z的取值通过加速度传感器采集。合速度阈值可记作A，合速度阈值A的取值可以是900-1300(包含端点值)中的任一值，本申请对此不作限定。
可选地，除了上述条件(1)以外，相对稳定状态还可以通过以下条件(2)进行判断：当前帧加速度计合速度值与前一帧的加速度计合速度值差值是否不超过预定差值阈值。也就是说，如果当前帧的加速度计合速度值不大于合速度阈值，且，当前帧加速度计合速度值与前一帧的加速度计合速度值差值不超过预定差值阈值，则可以认为终端在当前帧是相对稳定状态；如果当前帧的加速度计合速度值大于合速度阈值，且，当前帧加速度计合速度值与前一帧的加速度计合速度值差值超过了预定差值阈值，则可以确定终端在当前帧不是相对稳定状态。
上述预定差值阈值的描述参考前文，为了简洁，这里不作赘述。
另外，此处可考虑引入缓存(buffer)，将当前帧的数据保存到缓存(buffer)中，以作为后续步骤503的依据。Buffer中保存的数据可以包括已经计算好的每帧的加速度计合速度值，或者，每帧的状态判断结果，对此不作具体限定。这里引入buffer的目的在于保存连续多帧的数据，便于后续判断步骤503使用。例如，buffer中始终维持最近5帧的数据。
以下可以通过连续多帧的数据判断终端是否处于相对稳定状态。
503，判断连续n帧是否均是稳定状态。
如果连续n帧均是稳定状态，则可以确定终端是稳定状态；如果连续n帧不满足均是稳定状态的条件，则认为终端是运动状态。
可以理解，连续n帧中每帧的状态都可以参考上述判断当前帧相对稳定状态的方式进行判断。
举例来说，如果连续n帧的加速度计合速度值都小于合速度阈值，且该连续n帧中第i帧的加速度计合速度值与第i-1帧的加速度计合速度值的差值小于预定差值阈值，i∈[2,n]，则可以确定终端是稳定状态。
可以理解，加速度计合速度值的大小取决于终端的运动状态。比如，终端的运动幅度越大，加速度计合速度值的取值越大。终端的运动幅度可以取决于终端所在的位置(比如，口袋中，用户的手中)以及用户的行为场景。
以用户的行为场景是走为例，当用户在走路时，终端可能有以下两种情形：终端在裤子口袋中；终端在用户手中。这两种状态的区别在于，若终端在裤子口袋中，那么随着用户走路，终端的运动幅度不会太大；若终端在用户手中，那么随着用户走路过程中手臂的摆动，终端也会随之大幅运动。图7示出了用户手持终端12走路的场景。从图7可以看到，当用户拿着手机走路时，随着手臂的摆动，终端12也会跟随用户的手发生运动。相比于图1的场景，图7场景下终端12的加速度计合速度值大于图1场景下终端12的加速度计合速度值。例如，图7场景下终端12的加速度计合速度值为900-1300(包含端点值)的任一值；图1场景下终端12的加速度计合速度值为500-800(包含端点值)中的任一值，比如，550，600,700等。
在判断终端的运动状态时，并不能简单以某帧的数据判断终端是运动状态还是稳定状态而是需要结合连续n帧的数据进行判断，这样能够避免终端在口袋模式下发生大幅晃动时对终端运动状态的误判，从而有助于确保判断结果的准确性。例如，终端在口袋模式下，偶尔也有可能会存在一次幅度较大的晃动，这次较大的晃动计算的加速度计合速度值大于合速度阈值，但这次较大的晃动是偶发性的，并不能说明终端就一定处于运动状态。
上述连续n帧的数据可以从502处引入的buffer中获取。举例来说，从buffer中可以获得连续n帧的加速度计合速度值，然后将每帧的加速度计合速度值与合速度阈值做对比。如果连续n帧的加速度计合速度值均大于合速度阈值，那么可以确定终端确为运动状态。如果连续n帧的加速度计合速度值的均小于合速度阈值，那么可以确定终端为在口袋中的稳定状态。另外，这里还将除了“连续n帧的加速度计合速度值均大于合速度阈值”之外的情形都认为是稳定状态。换种表述，如果不是“均大于”的情形，则认为终端为在口袋中的稳定状态。
504，基于503的判断结果，确定稳定状态标识(steady_flag)。
稳定状态标识用于标识终端是稳定状态还是运动状态。比如，当steady_flag取值为1时，表示终端为在口袋中的稳定状态；当steady_flag取值为0时，表示终端为运动状态。
如果503的判断结果为是(比如，连续n帧的加速度计合速度值都大于合速度阈值)，那么将steady_flag置0。如果503的判断结果为否，那么将steady_flag置1。
以上502-504是获取稳定状态标识的步骤。
505，将通过加速度传感器获得的3轴数据以及通过陀螺仪获得的3轴数据，输入到六轴融合算法模块。
506，六轴融合算法模块输出四元数。
507，基于四元数计算重力分量，进行头朝下判断。
508，基于四元数计算姿态角，进行姿态角判断。
四元数的获取方式，以及利用四元数计算姿态角以及重力分量的具体方式参考前文描述，这里不作赘述。
头朝下判断是指判断终端的第一重力分量(记作v.y)和第二重力分量(记作v.z)是否满足以下两个条件：(1)v.y和v.z两轴的乘积为负数；(2)v.y的绝对值大于第一阈值，v.z的绝对值小于该第一阈值。
姿态角判断是指判断俯仰角是否在预设角度范围内。
509，基于步骤507的判断结果确定头朝下标识(headdown_flag)，以及，基于步骤508 的判断结果确定俯仰角标识(pitch_flag)。
头朝下标识用于标识终端是否是头朝下。比如，当headdown_flag取值为1时，表示终端头朝下；当headdown_flag取值为0时，表示终端不是头朝下。具体地，如果508中的重力分量满足预设条件，终端是头朝下状态，则将headdown_flag置1；如果508中的重力分量不满足预设条件，则认为终端不是头朝下状态，则将headdown_flag置0。
俯仰角标识用于标识终端的俯仰角是否在预设角度范围。比如，当pitch_flag取值为1时，表示终端的俯仰角在预设角度范围；当pitch_flag取值为0时，表示终端的俯仰角不在预设角度范围。具体地，如果508中判断俯仰角在预设角度范围内，则将pitch_flag置1；如果508中判断俯仰角不在预设角度范围内，则将pitch_flag置0。
以上505-509是获得头朝下标识以及俯仰角标识的步骤。
应理解，上述步骤501，502-504，以及505-509可以理解为算法执行的三个分支，在具体实现时，该三个分支可以同时进行，步骤编号次序不代表三个分支之间的执行先后顺序。
510，判断稳定状态标识是否为1、头朝下标识是否为1、俯仰角标识是否为1以及环境光小于或等于第一光阈值。
其中，第一光阈值小于第二光阈值。
如果稳定状态标识为1、头朝下标识为1、俯仰角标识为1且环境光小于或等于第一光阈值，说明终端处于头朝下的口袋模式，则执行511。
另外，如果环境光大于第一光阈值，那么继续检测终端所处的环境光线，并执行512。
511，判断界面是AOD界面还是锁屏界面(或者说解锁界面)。
如果是AOD界面，则AOD熄灭。如果是锁屏界面，则进入防误触模式。
图8示出了防误触模式的界面显示图。如图8所示，界面801中向用户呈现“请勿遮挡屏幕顶端”字样以及相应的示意图。在防误触界面中，还呈现“防误触模式在下方滑动两次即可强行退出”的字样，即用户通过下滑两次控件802，即可退出防误触模式。可以理解，如果当前终端处于头朝下的口袋模式，用户不会执行下滑控件802的操作，那么终端会自动熄灭。
另外，在锁屏界面下，进入防误触的前提是终端的防误触模式已开启，或者，防误触模式功能固化在终端中(即无需用户开启防误触模式)。
图9示出了如何开启防误触模式的界面图。如图9所示界面，辅助功能控件901中包括防误触模式的选项902。用户通过点击选项902，可以选择打开或关闭防误触模式。图9所示界面中显示开启防误触模式的选项902。当用户开启该功能后，手机在锁屏界面下如果发生误触可以进入防误触模式，进入图8所示的界面。可以理解，辅助功能控件901中还包括其他功能控件的选项，比如图9中示出的无障碍、单手模式、快速启动及手势、智慧多窗以及定时开关机)，对此不作具体限定。
512，判断环境光是否大于第二光阈值。如果是，则AOD亮起；如果否，则AOD熄灭。
在本申请实施例中，无论终端中是否设置有接近光传感器，以上防误触方法都是适用的。
作为一种可能的实现方式，终端中设置有接近光传感器。相应地，图6中的方法还包 括：
513，通过接近光传感器判断是否接近。如果接近，则AOD熄灭；如果判断不接近，则跳转至510。
在某些场景下(比如终端放置在黑色衣物的口袋中)接近光传感器不是很灵敏，导致判断结果不准确。基于此，在接近光传感器判断为不接近时，还可以进一步结合上述510中的条件进行判断，以确定终端是否处于头朝下的口袋模式。
可以理解，图6-图9中的示例只是便于本领域技术人员进行理解，并不对本申请实施例的保护范围构成限定。
由上可知，本申请提供的防误触的方法，通过多传感器协同检测终端的环境光信息、头朝下信息、姿态角信息以及运动信息，并根据这些信息确定终端是否处于头朝下的口袋模式能够有效解决口袋模式下防误触的问题，极大提升用户体验。
