下面结合附图介绍本申请实施例提供的技术方案。
本申请实施例提供的识别触摸操作的方法可以应用于多种应用场景，例如图1B所示的指关节触摸操作识别场景，又例如图1C所示的边缘滑动操作识别场景，下面结合应用场景对识别触摸操作的方法进行详细介绍。
应用场景一，指关节触摸操作识别场景。
图2为本申请实施例提供的识别指关节触摸操作的***架构示意图。
如图2所示，该***架构由下向上依次包括硬件层、内核层以及应用层。
内核层是硬件和软件之间的层。内核层包含操作***(operating system，OS)驱动，OS驱动为可以使***和硬件层通信的特殊程序，为硬件层与操作***的通信提供了接口。
硬件层可以包括触摸板、与触摸板连接的至少一个形变量传感器和微控制单元(microcontroller unit，MCU)，MCU分别与触摸板、至少一个形变量传感器连接。在本申 请实施例中，新增了形变量传感器用于识别指关节触摸。本申请涉及的形变量传感器可以为压电传感器、压电片、应变计、加速度传感器，也可以为能够实现采集形变量数据的其他传感器，本申请对此不作限制。在其它一些实施例中，形变量传感器也可以直接采集形变量波形数据。
其中，当电子设备为笔记本电脑时，笔记本电脑包括主机模组和显示模组，显示模组用于提供视觉输出，主机模组上具有触摸板(又称为触控板)，触摸板具有触摸传感器，可以采集触摸数据。当电子设备为平板电脑或者手机时，触摸传感器与显示屏组成触摸屏，也称“触控屏”，既可以采集触摸数据，也可以提供视觉输出。在以下的实施例中，是以电子设备为笔记本电脑为例进行说明的，如果将本申请方案应用在平板电脑或者手机，触摸板的实现方式也可以应用于触摸屏上，具体实现方式参考笔记本电脑的实现方式。
形变量传感器为本申请实施例中的新增器件，用于获取用户对触摸板进行操作时采集触摸板形变量数据。形变量传感器可以部署于触摸板的下方，当部署多个形变量传感器时，可以将多个形变量传感器等间距均匀部署于触摸板下方，又或者采用轴对称方式部署于触摸板下方，又或者采用中心对称方式部署于触摸板下方，本申请对于多个形变量传感器或者单个形变量传感器的布局方式不作限制。
MCU可以用于对触摸数据和触摸板形变量数据进行采集和处理，例如将形变量数据处理为形变量波形数据。MCU还可以用于根据触摸数据和形变量数据进行指关节触摸操作的识别。在MCU完成对触摸操作的识别后，且触摸操作为指关节触摸操作，则将指关节事件通过OS驱动上报给OS侧应用。
应用层可以包括一系列OS侧应用和OS，OS包括各种***应用程序接口，OS侧应用为OS的预装应用，OS侧应用可以通过调用***应用程序接口(application programming interface，API)来触发指关节触摸操作对应相关的功能，指关节触摸操作对应的功能可通过OS侧应用进行自定义。OS侧应用可以提供用户界面给用户，以便于用户在用户界面上自行定义指关节触摸操作对应的功能。
下面结合实施例对本申请实施例提供的识别触摸操作的方法进行详细说明。
本申请实施例中，电子设备的触摸板可以接收至少一个触摸操作，比如在某些场景中，用户手指的指关节在短时间内两次接触触摸板时，会在触摸板上产生两个触摸操作，为了分别识别这两个触摸操作是否为指关节触摸操作，采用以下实施例中的识别触摸操作的方法分别针对这每个触摸操作进行识别。下面的实施例仅以识别一个触摸操作为例，并不限定触摸板上只接收到一个触摸操作。可以理解的是，这里的一个触摸操作指的是单指关节触摸屏幕一次，或者是双指关节一起同时触摸屏幕一次，又或者更多指关节同时触摸屏幕一次。
图3为本申请实施例提供的识别触摸操作的方法的流程示意图。该方法可以适用于具有触摸板的电子设备，触摸板设有形变量传感器。如图3所示，该方法包括以下步骤：
S301，电子设备接收作用于触摸板的第一触摸操作。
S302，电子设备响应于第一触摸操作，获取至少一个形变量传感器采集触摸板的形变量数据、以及触摸板采集的触摸数据。
电子设备中的每个形变量传感器可以周期性采集形变量数据，也可以持续采集形变量数据，存放于数据缓冲区，电子设备可以在接收到第一触摸操作时，从数据缓冲区中获取 形变量数据，例如，可以使用第一时段内采集的形变量数据来识别指关节触摸操作。上述S302中，每个形变量传感器采集一个形变量数据，至少一个形变量传感器可以采集至少一个形变量数据，以电子设备设有5个形变量传感器为例，那么可以采集到5个形变量数据。电子设备可以根据形变量数据，生成形变量波形数据。
在一种实现方式中，使用第一时段内采集的形变量数据来识别指关节触摸操作，第一时段可以包括第二时段和第三时段，其中，第二时段包括从波形选取开始时间到第一触摸操作的触摸发生时间之间的时段，第三时段包括从第一触摸操作的触摸发生时间到波形选取结束时间之间的这段时间。如此，在选取形变量波形数据时，可能会选取到不包括第一触摸操作的整个生命周期的波形，例如，第一触摸操作的整个生命周期包括10秒，以第二时段为1秒，第三时段为5秒为例，本申请实施例选取第一触摸操作的触摸发生时间之前的1秒内的形变量波形以及触摸发生时间之后的5秒内的形变量波形识别触摸操作，可以在第一触摸操作开始后达到5秒时，就可以根据选取的形变量波形识别触摸操作，而不用等待第一触摸操作的整个生命周期结束(至少要等10秒)之后才能识别触摸操作，从而加快从触摸操作触摸发生时间至识别出第一触摸操作是否为指关节触摸操作的过程，从而快速响应第一触摸操作对应的功能。
下面具体地结合图4，示例性说明一种形变量传感器采集的形变量波形选取方式。
图4为本申请实施例提供的形变量波形示意图。如图4所示，从触摸发生时间向前偏移t1对应的时间作为波形选取开始时间，触摸发生时间之后的一个时间作为波形选取结束时间，选取时间长度t2的形变量波形。
在另一种实现方式中，使用第一时段内采集的形变量数据来识别指关节触摸操作，第一时段可以包括第一触摸操作的生命周期对应的第四时段、第四时段之前的第五时段、以及第四时段之后的第六时段，第一触摸操作的生命周期为第一触摸操作从开始接触触摸板至离开触摸板的过程。在第一触摸操作的生命周期内，触摸板会产生形变量，而且形变量会持续变化，形成波形，每个形变量传感器都可以采集到形变量变化形成的形变量波形数据。本申请实施例中将第一触摸操作的生命周期对应的整个时段称为第四时段。
电子设备在获取形变量波形数据时，可以先确定波形选取开始时间和波形选取结束时间，波形选取开始时间可以为第一触摸操作的生命周期开始前的一个时间，这段时间可以称为第五时段，波形选取结束时间可以为第一触摸操作的生命周期结束后的一段时间，这段时间可以称为第六时段。也就是说，从波形选取开始时间至波形选取结束时间之间的时段称为第一时段，依次包括第四时段、第五时段和第六时段。
第一触摸操作作用于触摸板上时，触摸板可以采集到第一触摸操作在触摸板上的触摸数据，例如包括触摸位置的坐标数据和触摸图像数据，其中触摸图像数据如图5中(a)和(b)所示，用户手指触摸到触摸板上形成一个触摸区域，即黑色区域，通过计算该黑色区域的面积，即可知触摸操作形成的触摸区域的面积。应理解，图5中的黑色区域仅用于示例触摸区域，在现实操作过程中，手指接触触摸板时可以显示黑色区域，当然也可以为显示为其它颜色的触摸区域，也可以不显示黑色区域，即用户看不到触摸区域的变化。
S303，电子设备根据至少一个形变量数据和触摸数据，识别第一触摸操作是否为指关节触摸操作。若是，则执行S304；若否，则执行S305。
本申请实施例中，通过新增设置的形变量传感器，采集手指触摸时触摸板的形变量数据，以避免各种干扰(例如电子设备自身状态以及周围环境的干扰)影响到用于识别指关 节触摸操作所需数据的有效性，从而提升识别率，降低误触率，提升用户体验。
在一种可能的实施方式中，电子设备可以从多个形变量传感器采集的多个形变量数据生成的形变量波形数据中，确定出至少一个较优的形变量波形数据，然后根据较优的形变量波形数据，识别第一触摸操作是否为指关节触摸操作。又或者，电子设备根据最优的形变量波形数据来识别第一触摸操作是否为指关节触摸操作。
在一种可能的实施方式中，电子设备从至少一个形变量波形数据中确定出较优的形变量波形数据，可以通过以下方式实现：电子设备计算至少一个形变量波形数据中每个形变量波形数据的波形中的波峰与波谷之间的形变量差值，电子设备将至少一个形变量波形数据中波形的波峰与波谷之间的形变量差值大于预设阈值的形变量波形数据，确定为较优的形变量波形数据。在另一种可能的实现方式中，将波形的波峰与波谷之间形变量差值最大的波形数据作为最优波形数据。形变量差值最大的形变量波形数据，最接近第一触摸操作对触摸板产生的实际形变量，根据该形变量差值最大的形变量波形数据进行识别，可以提升触摸板上不同区域的指关节触摸操作识别的有效性和一致性，提升用户体验。
下面结合图4，对计算任一个形变量波形数据的波形中的波峰与波谷之间的形变量差值进行介绍。
如图4所示的第一时段的形变量波形数据的波形，并不是一个完整周期的波形，即图4中的时间长度t2内的波形，其波峰为L1，波谷为L2，该形变量波形数据在第一时段的波形中的波峰与波谷之间的形变量差值为L1-L2。
在一种可能的实施方式中，上述根据较优的(或最优的)形变量波形数据和触摸数据，识别第一触摸操作是否为指关节触摸操作，可以通过以下方式实现：电子设备从较优的(或最优的)形变量波形数据中提取波形特征，例如，该波形特征可以包括但不限于如图5中(c)和(d)所示的波形振幅和波形的频率等特征，其中，图5中(c)的形变量波形的振幅较大、波形较窄，图5中(d)所示的形变量波形振幅较小、波形较宽，本申请实施例中，形变量波形越窄的波形，在波形的一个振动周期内，其振动频率越大，振动频率为振动周期的倒数；形变量波形越宽，在波形的一个振动周期内，其振动频率越小。电子设备从触摸数据中提取触摸图像特征，触摸图像特征可以包括但不限于触摸位置的坐标、触摸区域的面积，然后，电子设备可以根据波形特征、触摸图像特征以及指关节触摸识别模型，识别第一触摸操作是否为指关节触摸操作，指关节触摸识别模型为根据预先采集的指关节触摸操作对应的波形特征和触摸图像特征训练得到的。其中，指关节触摸识别模型为可以实现本申请识别指关节触摸操作的任意模型，例如可以为神经网络模型，本申请对此不作限定。
在一个示例中，波形特征中振幅大于或等于振幅阈值、振动频率大于或等于频率阈值、且触摸图像特征中触摸区域的面积小于或等于面积阈值，电子设备识别第一触摸操作为指关节触摸操作；波形特征中振幅小于振幅阈值、振动频率小于频率阈值、且触摸图像特征中触摸区域的面积大于面积阈值，则电子设备识别第一触摸操作为非指关节触摸操作。
图5为本申请实施例提供的指关节触摸操作与非指关节触摸操作的特征差异的示意图。如图5中(a)所示的指关节触摸操作的触摸区域，其对应的形变量波形的振幅大于或等于振幅阈值、振动频率大于或等于频率阈值，触摸区域的面积小，如图5中(b)所示的非指关节触摸操作的触摸操作，其对应的形变量波形的振幅小于振幅阈值、振动频率小于频率阈值，触摸区域的面积大。
S304，电子设备识别第一触摸操作为指关节触摸操作，触发第一触摸操作对应的第一响应功能。
其中，第一响应功能可以为***预设或用户自定义。例如，识别出来是指关节触摸操作以后，就弹出设置界面，用于设置屏幕亮度或者音量大小等等。以第一响应功能为设置音量功能为例，电子设备可以在识别第一触摸操作为指关节触摸操作后，触发设置音量功能，也就是说，无论是单指还是双指实现的指关节触摸操作，该指关节触摸操作对应的响应功能都设置为同一功能，这种情况下可以不用判断第一触摸操作使用的手指数量。
上述图3所示的实施例，可以适用于单指的单次指关节触摸操作，也适用于多指(例如两个手指)的单次指关节触摸操作，以两个手指的单次指关节触摸操作为例，这两个手指的指关节同时触摸到触摸板，或者，这两个手指的指关节触摸到触摸板的时间差很短，可以忽略不计。在实际应用中，可以设置该时间差的具体数值，例如设置为1ms，本申请实施例对于时间差的具体数值不作限定。举个例子，用户食指和中指一起敲击触摸板，食指和中指敲击触摸板的时间差小于1ms，即认为食指和中指实现了一次双指关节单击操作。
在其它一些实施例中，可以为单指指关节单击操作和双指指关节单击操作设置不同的响应功能，电子设备可以在每一次识别出触摸操作为指关节触摸操作时，根据触摸图像数据判断用于实现指关节触摸操作所使用的手指数量，以第一触摸操作识别为指关节触摸操作为例，如果是单个手指实现该第一触摸操作，即为单指关节单击操作，如果是两个手指实现该第一触摸操作，即为双指关节单击操作。在其它实施例中，也可以是识别出两次甚至多次连续的指关节触摸操作之后，判断指关节触摸操作使用的手指数量。本申请对于实现指关节触摸操作的手指数量的判断时机不作限定。
S305，不作任何处理。
上述实施例中，提供了识别一个触摸操作(即第一触摸操作)是否为指关节触摸操作的具体实现方式，在其它一些实施例中，在电子设备的触摸板接收第一触摸操作之后，在预设时长内可能会接收到其它的触摸操作，例如触摸板接收到第二触摸操作，此时，可以判断这两个触摸操作是否为指关节双击操作，即使用指关节连续快速地敲击两下触摸板。在实际应用中，可以设置该预设时长的具体数值，例如设置为10ms，本申请实施例对于预设时长的具体数值不作限定。
下面介绍如何确定第一触摸操作和第二触摸操作是否为指关节双击操作。
一种可能的实施方式中，若第一触摸操作与第二触摸操作满足第一预设条件，则确定第一触摸操作与第二触摸操作为指关节双击操作，其中，第一预设条件包括以下三项内容：第一项，第一触摸操作与第二触摸操作均为指关节触摸操作；第二项，第一触摸操作作用于触摸板的时间与第二触摸操作作用于触摸板的时间之间的间隔小于时间阈值；第三项，第一触摸操作的位置与第二触摸操作的位置之间的距离小于距离阈值。
若第一触摸操作与第二触摸操作不满足第一预设条件，即不满足第一预设条件中的任一项或多项内容，则确定第一触摸操作与第二触摸操作为非指关节双击操作。在一种可能的实现方式中，先分别识别第一触摸操作与第二触摸操作是否为指关节触摸操作，在识别出第一触摸操作与第二触摸操作均为指关节触摸操作之后，然后再判断每个触摸操作使用的手指数量，例如，若每个触摸操作都使用单个手指，确定为单指关节双击操作，若每个触摸操作使用两个手指，确定为双指关节双击操作。在另一种可能的实现方式中，在判断 每次触摸操作是否为指关节触摸操作的同时就直接判断该次触摸操作的手指数量。即本申请对于判断是双指关节还是单指关节的时机不做具体限定。下面对指关节双击操作的响应功能进行举例说明。在一个示例中，电子设备识别第一触摸操作与第二触摸操作为单指关节双击操作，触发***截屏功能；电子设备识别第一触摸操作与第二触摸操作识别为双指关节双击操作，触发***录屏功能。在其它一些实施例中，电子设备识别第一触摸操作与第二触摸操作为单指关节双击操作，触发***录屏功能；电子设备识别第一触摸操作与第二触摸操作识别为双指关节双击操作，触发***截屏功能。
下面结合图2，提供一个识别触摸操作的方法的详细示例。
请参见图6，为本申请实施例提供的识别触摸操作的方法的另一种流程示意图。具体的，所述流程包括：
S601，电子设备中的多个形变量传感器周期性向MCU上报采集的形变量数据，MCU将多个形变量数据存放于数据缓冲区。
S602，当触摸板接收到第一触摸操作时，MCU获取第一触摸操作对应的触摸数据，并从数据缓冲区中获取第一时段内的多个形变量数据，并根据形变量数据生成形变量波形数据。
其中，第一时段为波形选取开始时间与波形选取结束时间之间的时段，其中，触摸操作发生时间往前一段时间作为波形选取开始时间，再往后一定时间作为波形选取结束时间。
S603，MCU从多个形变量波形数据中选取波形中的波峰与波谷的差值最大的形变量波形数据作为最优的形变量波形数据。
S604，MCU根据触摸数据和最优的形变量波形数据，基于内置的指关节触摸识别模型进行特征提取，从触摸数据中提取触摸图像特征，从最优的形变量波形数据中提取波形特征。
S605，MCU基于触摸图像特征和波形特征进行分类识别，判断第一触摸操作是否为指关节触摸操作。若是，执行S606；否则，执行S618。
S606，MCU判断第一触摸操作使用的手指数量；若为单手指或双手指，执行S607；若为多手指，执行S618。需要说明的是，本申请并不限定识别手指数量的时机。
在S606中，若MCU判断第一触摸操作使用的手指数量为多手指(指的是至少为三个手指)，则认为第一触摸操作是误触操作，不作任何处理。
S607，MCU确定触摸板是否接收到第二次指关节触摸操作。若是，执行S612；否则，在第一触摸操作使用单手指时执行S608，在第一触摸操作使用双手指时执行S610。
S607的具体实现原理请参见前文的识别第一触摸操作是否为指关节触摸操作的实现方式，此处不重复赘述。
S608，MCU通过OS驱动向OS侧应用上报单指关节单击事件。

应用场景二，边缘滑动操作识别场景。
图7为本申请实施例提供的边缘滑动操作识别的架构示意图。
如图7所示，该***架构由下向上依次包括硬件层、内核层以及应用层。
内核层是硬件和软件之间的层。内核层至少包含OS驱动，OS驱动为可以使***和硬件设备通信的特殊程序，为硬件设备到操作***提供了接口。
硬件层可以包括触摸板、与触摸板连接的震动器件和MCU，MCU分别与触摸板、至少一个震动器件连接。
其中，当电子设备为笔记本电脑时，笔记本电脑包括主机模组和显示模组，显示模组用于提供视觉输出，主机模组上有触摸板(又称为触控板)，触摸板具有触摸传感器，可以采集触摸数据。当电子设备为平板电脑或者移动手机时，触摸传感器与显示屏组成触摸屏，也称“触控屏”，既可以采集触摸数据，也可以提供视觉输出。在以下的实施例中，是以电子设备为笔记本电脑为例进行说明的，如果将本申请方案应用在平板电脑或者手机，触摸板的实现方式也可以应用于触摸屏上，具体实现方式参考笔记本电脑的实现方式。
在本申请提供的实施例中，通过添加震动器件使得用户感知到功能已被触发，提升用户体验。至少一个震动器件可以布局于触摸板的多个区域，例如，至少一个震动器件等间距均匀分布于触摸板下方，本申请对于至少一个震动器件的布局方式不作限制，又例如至少一个震动器件采用轴对称方式分布于触摸板下方，又例如至少一个震动器件采用中心对称方式分布于触摸板下方，本申请对于至少一个震动器件的布局方式不作限制，震动器件用于输出震动提示。
MCU可以用于在用户对触摸板的边缘特定区域进行滑动操作时采集滑动时各个触摸点的触摸数据。MCU还可以用于进行边缘滑动操作的识别。在MCU完成对触摸操作的识别后，且触摸操作为边缘滑动触摸操作，则将边缘触控事件通过OS驱动上报给OS侧应 用。
应用层可以包括一系列OS侧应用和OS，OS包括各种***应用程序接口，OS侧应用为OS的预装应用，OS侧应用可以通过调用***API来触发边缘滑动操作相关的功能，同时触发震动器件输出震动提示，边缘滑动操作对应的功能可通过OS侧应用进行自定义。OS侧应用可以提供用户界面给用户，以便于用户在用户界面上自行定义边缘滑动操作对应的功能。
下面结合实施例对本申请实施例提供的识别触摸操作的方法进行详细说明。
图8为本申请实施例提供的识别触摸操作的方法的流程示意图。该方法可以适用于具有触摸板的电子设备，触摸板设有震动器件。如图8所示，所述方法的流程包括：
S801，电子设备接收作用于触摸板的第三触摸操作。
S802，电子设备识别第三触摸操作是否为边缘滑动触摸操作。若是，则执行S803；若否，则执行S804。
为了提高边缘滑动触摸操作识别的成功率，本申请提供了一种识别方法，具体的，步骤S802的实现方式如下：电子设备响应于第三触摸操作，采集触摸数据，此处触摸数据可以包括触摸板上的各触摸点的坐标数据和任意两个相邻的触摸点之间的间隔时间，然后根据触摸数据确定第三触摸操作是否为滑动触摸操作；例如，第三触摸操作对应的各触摸点中任意两个相邻的触摸点之间的间隔时间大于时间阈值，则识别第三触摸操作不是滑动触摸操作，那么电子设备就判断第三触摸操作不是边缘滑动触摸操作，而是误触操作，不作任何处理。若任意两个相邻的触摸点之间的间隔时间小于或等于时间阈值，识别出第三触摸操作为滑动触摸操作，则继续识别第三触摸操作是否为边缘滑动触摸操作。一种可能实现识别第三触摸操作是否为边缘滑动触摸操作的实现方式为：电子设备根据各触摸点的坐标数据，计算各触摸点的坐标数据的拟合直线与第一方向的夹角、以及每个触摸点在第二方向上的投影点与第三触摸操作的起始点在第二方向上的投影点之间的距离差值，根据夹角以及各个触摸点对应的距离差值，识别第三触摸操作是否为边缘滑动触摸操作；其中，第一方向为沿着触摸板第一侧边的方向，第一侧边为第三触摸操作的触摸位置所在的侧边，第二方向为与第一侧边垂直的方向。
下面结合图9和图10，说明如何计算夹角和距离差值。
如图9所示，用户手指在触摸板的第一侧边的边缘特定区域(边缘特定区域例如图1C所示的上边缘滑动区域)滑动，形成从滑动起点到滑动终点的滑动轨迹，其滑动方向为沿着第一侧边的方向。以触摸轨迹的包括5个触摸点(可以通过采样得到)为例，电子设备采集触摸板上的5个触摸点在触摸板所在的平面坐标系的坐标数据。这5个触摸点的坐标数据进行直线拟合，然后计算拟合直线与第一方向的夹角，第一方向为图9中的滑动方向，与触摸板的第一侧边平行，与触摸板的第二侧边垂直。
然后，计算每个触摸点在第一方向上的投影点与第三触摸操作的起始点在第一方向上的投影点之间的距离差值，并从5个触摸点对应的距离差值中选择距离差值最大的一个距离差值，即为距离差值最大值。如图10中所示，距离差值最大值为第2个触摸点对应的最大距离t。
在一种可能的实施方式中，若夹角以及距离差值最大值满足预设条件，识别第三触摸操作为边缘滑动触摸操作，则确定第三触摸操作为边缘滑动触摸操作，其中，预设条件包 括：夹角小于或等于夹角阈值、且距离差值最大值小于或等于差值阈值。
在一个示例中，若夹角以及距离差值最大值不满足预设条件，即夹角大于夹角阈值或者距离差值最大值大于阈值，则确定第三触摸操作不是边缘滑动触摸操作。
通过上述实施方式，基于第三触摸操作的各触摸点的坐标数据识别边缘滑动触摸操作，可以降低误触率，提升识别率。
在其它一些实施例中，上述触摸数据还可以包括触摸面积，为了进一步降低误触率，在根据夹角以及各个触摸点对应的距离差值，识别第三触摸操作是否为边缘滑动触摸操作之前，MCU还可以先确定第三触摸操作对应的触摸面积是否小于或等于预设阈值，若是，则继续根据夹角和距离差值识别第三触摸操作，若否，则识别第三触摸操作为误触操作，例如，用户手掌触摸到触摸板，手掌的触摸面积比较大，这种情况下通过计算触摸操作的触摸面积可以识别出来为误触操作。
S803，电子设备触发边缘滑动触摸操作对应的第二响应功能，并通过震动器件输出震动提示。
上述S803中的执行边缘滑动触摸操作对应的第二响应功能可以通过以下方式实现：在识别出第三触摸操作为边缘滑动触摸操作之后，电子设备还可以基于边缘滑动触摸操作在第一方向上的滑移动距离m或者移动速度，触发相应的响应功能。如图10所示，滑动距离可以为边缘滑动触摸操作的滑动终点在第一方向上的投影点与滑动起点在第一方向上的投影点之间的距离m。
例如，边缘滑动触摸操作对应的滑动距离为0.5cm，触发一次边缘触控事件，边缘滑动触摸操作对应的滑动距离为1cm，触发两次边缘触控事件。又例如，滑动距离均为0.5cm的两个边缘滑动触摸操作，移动速度快的边缘滑动触摸操作调节音量增大2dB，移动速度慢的边缘滑动触摸操作调节音量增大1dB。
一种可能的实现方式中，上述S803中的通过震动器件输出震动提示可以通过以下方式实现：通过与第三触摸操作对应的每个触摸点距离小于距离阈值的所有震动器件输出震动提示。举个例子，以距离阈值为1cm为例，可以通过与每个触摸点距离1cm范围内的所有震动器件输出震动提示。
另一种可能的实现方式中，上述S803中的通过震动器件输出震动提示可以通过以下方式实现：电子设备通过与第三触摸操作对应的每个触摸点距离最近的k个震动器件输出震动提示，k为正整数。
以第一触摸点为例，电子设备还可以根据第一触摸点分别与k个震动器件之间的距离、以及第一映射关系，确定与第一触摸点距离最近的k个震动器件对应的震动信号值，第一映射关系包括距离与震动信号值之间的映射关系，第一触摸点为第三触摸操作对应的各个触摸点中的任意一个触摸点。从而使得与所述第一触摸点距离最近的k个震动器件输出的震动信号到达所述第一触摸点时的震动强度一致。其中，该映射关系可以为列表的形式，也可以为函数公式。
以k为2为例，如图11所示，一个触摸点O周围有两个震动器件，其中震动器件1与触摸点O的距离为s1、震动器件2与触摸点O的距离为s2，那么这两个震动器件就是与触摸点O最近的震动器件，基于距离与震动信号值之间的映射关系，可以确定出与s1对应的震动信号值x1、以及与s2对应的震动信号值x2，然后将震动信号值x1发生至震动器件1，将震动信号值x2发生至震动器件2，震动器件1根据震动信号值x1输出震动提 示，震动器件2根据震动信号值x2输出震动提示。这样用户在触摸点O处感受到的两个震动器件的震动强度一致。
本申请实施例中，在识别出边缘滑动触摸操作时，通过在触摸板上设置的震动器件输出震动反馈，以指示用户滑动功能已触发，可以提升用户体验。
S804，电子设备识别出第三触摸操作为误触操作，不作任何处理。
下面结合图7，提供另一个识别触摸操作的方法的详细示例。
请参见图12，为本申请实施例提供的识别触摸操作的方法的另一种流程示意图。具体的，所述流程包括：
S1201，当触摸板接收到第三触摸操作，MCU获取第三触摸操作对应的触摸数据，其中，触摸数据包括各触摸点的坐标数据、各触摸点中任意相邻两个触摸点之间的时间间隔以及触摸面积。
S1202，MCU确定是否第三触摸操作对应的触摸面积小于或等于预设阈值、且第三触摸操作对应的各触摸点中任意相邻的两个触摸点之间的时间间隔小于时间阈值、且触摸位置在边缘特定区域内，若是，则执行步骤S1203；否则，执行S1211。
S1203，MCU根据第三触摸操作对应的各触摸点的坐标数据拟合直线。
S1204，MCU计算拟合直线与第一方向的夹角α。
其中，第一方向为沿着触摸板第一侧边的方向，第一侧边为第三触摸操作的触摸位置所在的侧边。
S1205，MCU计算每个触摸点在第二方向上的投影点与第三触摸操作的起始点在第二方向上的投影点之间的距离差值，确定距离差值最大值t。
其中，第二方向为与第一侧边垂直的方向。
S1206，MCU确定是否夹角α小于或等于夹角阈值且距离差值最大值t小于或等于差值阈值，若是，则执行步骤S1207；否则，执行S1211。
S1207，MCU识别第三触摸操作为边缘滑动触摸操作，基于边缘滑动触摸操作在第一方向上的滑移动距离m或者移动速度，向OS侧应用上报边缘滑动触摸事件。
S1208，OS侧应用调用OS API触发边缘滑动触摸操作对应的响应功能。
S1209，MCU基于当前的触摸点与震动器件的距离，选取距离最小的k个震动器件，计算所述k个震动器件分别对应的震动信号值。
S1210，MCU向k个震动器件分别发送各自的震动信号值，使得k个震动器件根据接收到的震动信号值进行震动提示。
S1211，MCU识别第三触摸操作为误触操作，不作处理。
