因此，如何提高识别误触的准确率是本领域技术人员目前需要解决的技术问题。

若检测到触控结构被触发，则获取至少两个压力传感器采集的压力值；其中，所述触控结构和至少两个所述压力传感器均设置于所述可穿戴设备的 外壳侧壁，至少两个所述压力传感器分别与所述触控结构的距离不相等；
判断所有所述压力传感器采集的压力值是否均在对应的参考压力区间；
若是，则响应所述触控结构被触发的事件；
若否，则判定所述触控结构被误触，不响应所述触控结构被触发的事件。
可选的，在获取至少两个压力传感器采集的压力值之前，还包括：
接收参考压力区间设置指令，并输出提示用户在非误触条件下触发所述触控结构的提示信息；
获取至少两个所述压力传感器采集的参考压力值，并根据所述参考压力值设置参考压力区间。
可选的，在获取至少两个压力传感器采集的压力值之前，还包括：
采集所述可穿戴设备的佩戴状态数据；其中，所述佩戴状态数据包括体征传感器、距离传感器和运动传感器中任一种或任几种传感器采集的数据；
根据所述佩戴状态数据判断所述可穿戴设备是否处于已佩戴状态；
若是，则进入所述获取至少两个压力传感器采集的压力值的步骤；
若否，则执行所述可穿戴设备未佩戴时所述触控结构被触发对应的处理策略。
可选的，在获取至少两个压力传感器采集的压力值之前，还包括：
采集所述压力传感器分别处于按压状态和未按压状态时的压力测试值，根据所述压力测试值对所述压力传感器进行校准。
本申请还提供了一种可穿戴设备，包括触控结构、至少两个压力传感器、微控制单元和主控芯片；
其中，所述触控结构和至少两个所述压力传感器均设置于所述可穿戴设备的外壳侧壁，至少两个所述压力传感器分别与所述触控结构的距离不相等，所述微控制单元用于将所述压力传感器采集的压力值发送至所述主控芯片；
所述主控芯片用于若检测到触控结构被触发，则通过所述微控制单元获取至少两个压力传感器采集的压力值；还用于判断所有所述压力传感器采集的压力值是否均在对应的参考压力区间；若是，则响应所述触控结构被触发的事件；若否，则判定所述触控结构被误触，不响应所述触控结构被触发的事件。
可选的，所述触控结构包括设置于所述可穿戴设备的外壳侧壁的滚轮， 至少两个所述压力传感器设置于所述外壳侧壁且分别位于所述触控结构的两侧。

本申请还提供了一种存储介质，其上存储有计算机程序，所述计算机程序执行时实现上述防误触方法执行的步骤。
本申请提供了一种防误触方法，应用于可穿戴设备，所述防误触方法包括：若检测到触控结构被触发，则获取至少两个压力传感器采集的压力值；其中，所述触控结构和至少两个所述压力传感器均设置于所述可穿戴设备的外壳侧壁，至少两个所述压力传感器分别与所述触控结构的距离不相等；判断所有所述压力传感器采集的压力值是否均在对应的参考压力区间；若是，则响应所述触控结构被触发的事件；若否，则判定所述触控结构被误触，不响应所述触控结构被触发的事件。
本申请在检测到触控结构被触发后，获取至少两个压力传感器采集的压力值。由于触控结构和压力传感器均设置于可穿戴设备的外壳侧壁，用户触碰触控结构时，外壳侧壁的形变将会引起压力传感器采集的压力值的变化。本申请中至少两个压力传感器与触控结构之间的距离不相等，因此非误触条件下触控结构被触发时，对于压力传感器采集的压力值的影响不同。本申请根据所有所述压力传感器采集的压力值与对应的参考压力区间进行比较，若均在参考压力区间内，则说明不存在误触；若不均在参考压力区间内，则说明触控结构被误触，此时可以不响应所述触控结构被触发的事件。本申请的防误触方案能够检测多种场景下的误触现象，提高了识别误触的准确率。本申请同时还提供了一种可穿戴设备及一种存储介质，具有上述有益效果，在此不再赘述。
为了更清楚地说明本申请实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本申请的一部分附图，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据提供的附图获得其他的附图。
图1为本申请实施例所提供的一种防误触方法的流程图；
图2为本申请实施例所提供的一种可穿戴设备的架构示意图；
图3为本申请实施例所提供的一种压力传感器位置布局示意图；
图4为本申请实施例所提供的一种设置于壳体的压力传感器的贴附方式示意图；
图5为本申请实施例所提供的一种设置于触控结构的压力传感器的贴附方式示意图。
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，显然，所描述的实施例仅仅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在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
随着智能可穿戴技术的发展，常规的物理按键方式逐渐无法满足用户的需求和场景的切换，许多厂商都推出了滚轮等触控结构设计。由于这些触控结构存在易受力而产生误触发现象，例如，滚轮存在易受力而产生滚动的误触发现象(如手撑桌子时，大面积外壳都会有皮肤接触与压迫)。本申请通过以下几个实施例提供新的可穿戴设备防误触方案，能够以低成本的方案对上述缺陷进行规避。
下面请参见图1，图1为本申请实施例所提供的一种防误触方法的流程图，具体步骤可以包括：
S101：若检测到触控结构被触发，则获取至少两个压力传感器采集的压力值；
其中，本实施例可以应用于智能手表、手环、AR眼镜或VR头盔等可穿戴设备，上述可穿戴设备可以包括触控结构、至少两个压力传感器、微控制 单元MCU和主控芯片。压力传感器用于检测特定位置的压力值并将压力值通过微控制单元返回至主控芯片。上述触控结构和至少两个所述压力传感器均设置于可穿戴设备的外壳侧壁，至少两个所述压力传感器分别与所述触控结构的距离不相等。在获取至少两个压力传感器采集的压力值之前还可以存在对压力传感器进行校准的操作，例如可以采集所述压力传感器分别处于按压状态和未按压状态时的压力测试值，根据所述压力测试值对所述压力传感器进行校准。
本实施例中的触控结构可以包括按键或滚轮，用户可以通过按压或旋转的方式触发上述触控结构。触控结构与主控芯片连接，主控芯片可以检测到用户触发触控结构的事件，此时可以向微控制单元下发数据采集指令，以便获取各个压力传感器采集的压力值。还需要说明的是，按键可以是普通的可按压按键，也可是既可按压又可旋转的按键，滚轮可以是普通的可旋转滚轮，也可以是即可旋转也可按压的滚轮。滚轮被旋转时，外壳侧壁会受力发生形变，滚轮的旋转轴线可以平行于设置滚轮的外壳侧壁所在的平面或者平行于外壳侧壁的切平面。例如，当可穿戴设备的外壳大体呈矩形时，滚轮的旋转轴线可以平行于设置滚轮的外壳侧壁，具体地，可以与外壳侧壁的长边平行，也可以与外壳侧壁的短边平行；当可穿戴设备的外壳大体呈圆形时，滚轮的旋转轴线平行于设置滚轮的外壳侧壁的切平面。
S102：判断所有压力传感器采集的压力值是否均在对应的参考压力区间；若是，则进入S103；若否，则进入S104；
其中，上述参考压力区间为在未误触条件下触控结构被触发时所有压力传感器的压力值所在的区间。本实施例可以通过实际测试设置上述参考压力区间。
可以理解的是，当触控结构被用户正常触发时，用户的手指对于距离触控结构越近的压力传感器采集值的影响越大，因此可以基于压力传感器与未误触条件下的参考压力区间进行比较，与实现误触识别。
具体的，每一压力传感器都有其对应的参考压力区间，该参考压力区间与压力传感器的位置相关。在得到多个压力传感器采集的压力值的基础上，本实施例可以将每一压力传感器实际采集的压力值与对应的参考压力区间进行比较，若所有的压力传感器采集的压力值均在对应的参考压力区间，则判 定不存在误触；若所有的压力传感器采集的压力值不均在对应的参考压力区间，则判定存在误触。
S103：响应所述触控结构被触发的事件；
其中，若所有所述压力传感器采集的压力值均在对应的参考压力区间，则说明不存在误触现象，此时主控芯片可以按照预设处理逻辑响应触发所述触控结构的事件，如屏幕唤醒、音量调整、接听电话等。
S104：判定触控结构被误触，不响应所述触控结构被触发的事件。
其中，若所有所述压力传感器采集的压力值均在对应的参考压力区间，则说明存在误触现象，判定所述触控结构被误触，不响应触发所述触控结构的事件。
本实施例在检测到触控结构被触发后，获取至少两个压力传感器采集的压力值。由于触控结构和压力传感器均设置于可穿戴设备的外壳侧壁，用户触碰触控结构时，外壳侧壁的形变将会引起压力传感器采集的压力值的变化。本实施例中至少两个压力传感器与触控结构之间的距离不相等，因此非误触条件下触控结构被触发时，对于压力传感器采集的压力值的影响不同。本实施例根据所有所述压力传感器采集的压力值与对应的参考压力区间进行比较，若均在参考压力区间内，则说明不存在误触；若不均在参考压力区间内，则说明触控结构被误触，此时可以不响应所述触控结构被触发的事件。本实施例的防误触方案能够检测多种场景下的误触现象，提高了识别误触的准确率。
作为对于图1对应实施例的进一步介绍，在进行防误触检测之前还可以存在佩戴状态检测的方案，以便在可穿戴设备处于已佩戴状态下进行防误触检测，具体过程如下：
在获取至少两个压力传感器采集的压力值之前，采集所述可穿戴设备的佩戴状态数据；其中，所述佩戴状态数据包括体征传感器、距离传感器和运动传感器中任一种或任几种传感器采集的数据；根据所述佩戴状态数据判断所述可穿戴设备是否处于已佩戴状态；若是，则进入所述获取至少两个压力传感器采集的压力值的步骤；若否，则执行所述可穿戴设备未佩戴时所述触控结构被触发对应的处理策略。上述体征传感器可以为用于检测佩戴者心率 的传感器，也可以为用于检测佩戴者体温的传感器，还可以为同时检测心率和体温的传感器。
通过上述方式，可穿戴设备能够在检测到用户正常佩戴时，再执行上述S101～S104的防误触方案，进而能够规避用户未佩戴操作时防误触检测逻辑紊乱的情况。
作为对于图1对应实施例的进一步介绍，在压力传感器采集的压力值之前，还可以存在对各个压力传感器进行校准的操作。例如，可以在获取至少两个压力传感器采集的压力值之前，接收参考压力区间设置指令，并输出提示用户在非误触条件下触发所述触控结构的提示信息；获取至少两个所述压力传感器采集的参考压力值，并根据所述参考压力值设置参考压力区间。具体的，本实施例可以根据参考压力值±10％对应的压力值范围确定参考压力区间。通过上述方式能够快速确定非误触条件下的参考压力区间。
此外，若存在设置于触控结构的压力传感器时，可以通过以下方式设置参考压力区间：确定每一压力传感器被直接按压时的压力值区间，将设置于触控结构的压力传感器的压力值区间设置为该压力传感器的参考压力区间，将未设置于触控结构的压力传感器的压力值区间的补集设置为该压力传感器的参考压力区间。
本实施例可以按照是否设置于触控结构将所有的压力传感器划分为两类压力传感器，即远离触控结构的压力传感器和靠近触控结构的压力传感器，靠近触控结构的压力传感器为设置于触控结构将所有的压力传感器。基于上述方式误触的检测过程包括：首先采集未接触按压时各压力传感器的压力值，即得到各个压力传感器的压力最小值Tmin。各压力传感器的压力最小值Tmin可存在差异，可以基于上述差异对压力传感器进行校准。其次，采集远离触控结构的压力传感器被直接按压时(根据误触发场景设置，例如0.5～10N)采集的压力值范围M。然后，采集触控结构被触发(例如力度3～8N)时靠近触控结构的压力传感器采集的压力值范围S。在可穿戴设备使用过程中，若靠近触控结构的压力传感器实际采集的压力值在区间S内，且远离触控结构的压力传感器实际采集的压力值均在区间M外，视为正常触发，其余场景则均判定为误触发。
请参见图2，图2为本申请实施例所提供的一种可穿戴设备的架构示意图，如图2所示该设备可以包括：包括触控结构、至少两个压力传感器、微控制单元和主控芯片；
其中，所述触控结构和至少两个所述压力传感器均设置于所述可穿戴设备的外壳侧壁，至少两个所述压力传感器分别与所述触控结构的距离不相等，所述微控制单元用于将所述压力传感器采集的压力值发送至所述主控芯片；所述主控芯片用于若检测到触控结构被触发，则通过所述微控制单元获取至少两个压力传感器采集的压力值；还用于判断所有所述压力传感器采集的压力值是否均在对应的参考压力区间；若是，则响应所述触控结构被触发的事件；若否，则判定所述触控结构被误触，不响应所述触控结构被触发的事件。
本实施例在检测到触控结构被触发后，获取至少两个压力传感器采集的压力值。由于触控结构和压力传感器均设置于可穿戴设备的外壳侧壁，用户触碰触控结构时，外壳侧壁的形变将会引起压力传感器采集的压力值的变化。本实施例中至少两个压力传感器与触控结构之间的距离不相等，因此非误触条件下触控结构被触发时，对于压力传感器采集的压力值的影响不同。本实施例根据所有所述压力传感器采集的压力值与对应的参考压力区间进行比较，若均在参考压力区间内，则说明不存在误触；若不均在参考压力区间内，则说明触控结构被误触，此时可以不响应所述触控结构被触发的事件。本实施例的防误触方案能够检测多种场景下的误触现象，提高了识别误触的准确率。
进一步的，上述触控结构可以包括设置于所述可穿戴设备的外壳侧壁的滚轮，至少两个所述压力传感器设置于所述外壳侧壁且分别位于所述触控结构的两侧。上述触控结构可以包括按键，至少两个所述压力传感器设置于所述外壳侧壁且分别位于所述触控结构的两侧。
请参见图3，图3为本申请实施例所提供的一种压力传感器位置布局示意图，如图3所示，所述外壳侧壁上装设所述触控结构300的位置设置有至少一个压力传感器302，其他两个压力传感器301和303分别设置于触控结构的两侧，且呈对称分布。
进一步的，所有的压力传感器设置于同一FPC板或PCB板，所述FPC 板或所述PCB板贴附于所述可穿戴设备的外壳侧壁。请参见图4，图4为本申请实施例所提供的一种设置于壳体的压力传感器的贴附方式示意图，当可穿戴设备的外壳形变时，将会通过泡棉挤压焊接于PCB板或FPC板上的压力传感器，PCB板或FPC板设置于支架上。请参见图5，图5为本申请实施例所提供的一种设置于触控结构的压力传感器的贴附方式示意图，当触控结构被触发时，将会通过泡棉挤压焊接于PCB板或FPC板上的压力传感器。
本实施例提供了基于压力值检测的防误触设计，采用多个侧边压力传感器的设计，可以通过信号采集以及对应的软件控制逻辑，能够有效区分用户操作和误触发场景。
本申请还提供了一种存储介质，其上存有计算机程序，该计算机程序被执行时可以实现上述实施例所提供的步骤。该存储介质可以包括：U盘、移动硬盘、只读存储器(Read-Only Memory，ROM)、随机存取存储器(Random Access Memory，RAM)、磁碟或者光盘等各种可以存储程序代码的介质。
说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。对于实施例公开的装置而言，由于其与实施例公开的方法相对应，所以描述的比较简单，相关之处参见方法部分说明即可。应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以对本申请进行若干改进和修饰，这些改进和修饰也落入本申请权利要求的保护范围内。
还需要说明的是，在本说明书中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的状况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
