触摸操作的识别方法及装置 技术领域
本申请涉及触控技术领域，尤其涉及一种触摸操作的识别方法及装置。
背景技术
在触摸过程中，客户越来越倾向于使用被动式触摸物，为满足用户需求被动式触摸物的触摸接触点越来越细、越来越耐磨、越来越接近实际书写中所使用的硬质笔头。被动式触摸物触摸与手指触摸原理相同，被动式触摸物的触摸接触点越细越硬，在实际书写时在电容屏的接触面积远小于手指与电容屏的接触面积，电容屏需要提高对触摸接触点的感应量或降低感应的触摸门槛以适配触摸接触点较细的被动式触摸物。而主动式触摸物的触摸接触点通常也是一种导体，在配备较细或较硬的触摸接触点时，主动式触摸物的触摸接触点和被动式触摸物的触摸接触点在电容屏的触摸感应量是接近的，无法通过门槛限定的方式进行区分。
在主动式触摸物与被动式触摸物可以同时触摸书写的电容屏，使用主动式触摸物进行书写时，电容屏会识别到主动式触摸物的触摸操作，同时可能还会将主动式触摸物的触摸操作识别为被动式触摸物的触摸操作而进行输出，出现误识别的问题。

具体实施方式
本申请实施例提供的触摸操作的识别方法可以应用于电容屏，特别是主动式触摸与被动式触摸可以同时触摸书写的电容屏。所述电容屏安装于使用电容屏进行人机交互的终端上，所述终端包括但不限于交互平板、智能手机、可触控电脑、可触控手表等使用电容屏进行人机交互的终端。
终端的硬件部分由触控显示模组、整机模块(包括控制器)等部分所构成，由整体结构件结合到一起，其中触控显示模组包括电容屏、触控组件和背光灯组件，背光灯组件用于为电容屏提供背光光源，电容屏一般采用液晶显示装置，用于进行画面展示，触控组件设置在电容屏上或者设置在电容屏前端，用于采集用户的触控操作所产生的触控数据，并将采集的触控数据发送到整机模块进行处理。
在实际使用中，当用户通过手指或者触控笔等触控物体在电容屏上进行内容书写时，终端的触控组件将采集到触控数据，从而触控组件将该触控数据转换为触控点的坐标数据后发送到整机模块，或者将该触控数据发送到整机模块处由整机模块转换为触控点的坐标数据，整机模块获得触控点的坐标数据后，驱动电容屏显示书写笔迹。
现有技术中，在所述电容屏上执行触控操作以进行内容书写主要通过两种方式，一种是利用主动式触摸物针对电容屏进行触摸操作，在所述电容屏上产生主动式信号，所述主动式触摸物可以是主动式电容触摸笔，所述主动式电容触摸笔内部有电路，可以向电容屏主动发射信号进而在电容屏产生主动式信号；还有一种是利用被动式触摸物针对电容屏进 行触摸操作，在所述电容屏上产生被动式信号，所述被动式信号是通过与电容屏接触的触摸接触点吸收电信号影响电容屏的电容变化进而在电容屏产生的触摸信号，所述被动式触摸物可以是被动式电容触摸笔、手指以及其他可以通过吸收电信号引起电容屏的电容变化的物品或设备。
一般的，在所述电容屏上使用主动式触摸物进行书写时，主动式触摸物可能会通过触摸接触点吸收电信号进而影响电容屏的电容变化，所述电容屏容易误将所述主动式触摸物同时识别为被动式触摸物，从而在所述电容屏产生两种触摸信号，即主动式触摸物触摸产生的主动式信号和主动式触摸物触摸产生的被动式信号。其中主动式触摸物触摸产生的主动式信号为期望信号，而主动式触摸物触摸产生的被动式信号则属于杂讯。所述主动式信号是指主动式触摸物通过内部电路向电容屏主动发射信号而在电容屏产生的信号，所述主动式触摸物可以是主动式电容笔等可以主动发射信号的触摸物。所述被动式信号是指主动式触摸物或被动式触摸物通过吸收电信号影响电容屏的电容变化而在电容屏产生的信号，所述被动式触摸物可以是被动式电容笔或手等可以吸收电容屏表面电信号的触摸物。
采用本申请实施例可以通过扫描针对所述电容屏的触摸操作，在接收到由主动式触摸物触摸产生的第一触摸信号，且所述第一触摸信号为主动式信号时，根据所述第一触摸信号确定防误判区域，所述防误判区域用于将防误判区域内接收到的所述主动式触摸物触摸产生的第二触摸信号忽略，以使得仅基于所述主动式触摸物触摸产生的主动式信号显示书写轨迹，避免将主动式触摸物通过触摸接触点吸收电信号影响电容屏的电容变化生成的被动式信号对应的书写笔迹进行显示，保证电容屏对触摸操作的识别精准度，所述防误判区域跟随着主动式触摸物的移动而时刻变化着，所述第二触摸信号为被动式信号。触摸操作的识别装置，是触摸操作识别的核心装置，触摸操作的识别装置可以是具有电容屏的可触摸终端设备的终端系统中运行的系统进程，也可以是独立于可触摸终端设备以外的并与所述可触摸终端设备可靠连接的触摸操作的识别装置，主要用于对针对所述电容屏的触摸操作进行扫描识别并输出，触摸操作的识别装置可以在可触摸终端设备出厂时配置于终端系统中，或者可以由用户自行在可触摸终端设备中进行安装。终端系统具体可以为终端设备中配置的操作系统，例如：安卓系统、Windows系统、IOS系统、鸿蒙系统等。
下面将结合图1～图8，对本申请实施例提供的触摸操作的识别方法进行详细介绍。
请参见图1，为本申请实施例提供了一种触摸操作的识别方法的流程示意图。如图1所示，所述触摸操作的识别方法可以包括以下步骤S101～S105。
S101，扫描针对电容屏的触摸操作；
具体的，扫描针对所述电容屏的触摸操作，即扫描在所述电容屏上进行触摸操作时产生的触摸信号，所述触摸信号可以是主动式信号也可以是被动式信号。
所述主动式信号是由主动式触摸物触摸产生的触摸信号，所述主动式触摸物可以是主动式电容触摸笔，所述主动式电容触摸笔内部有电路，可以向电容屏主动发射信号，进而在电容屏产生触摸信号。
所述被动式信号可以是由被动式触摸物触摸产生的触摸信号，也可以是由主动式触摸物触摸产生的触摸信号。若所述被动式信号是由被动式触摸物触摸产生的触摸信号，所述被动式触摸物类似手指的触摸效应，通过与电容屏接触的触摸接触点吸收电信号，影响电容屏的电容变化，进而在电容屏产生触摸信号。所述被动式触摸物可以是被动式电容触摸笔、手指以及其他可以通过吸收电信号引起电容屏的电容变化的物品或设备。若所述被动式信号是由主动式触摸物触摸产生的触摸信号，所述主动式触摸物可以是主动式电容触摸笔，所述主动式电容触摸笔的笔尖是导电材料，在使用所述主动式电容触摸笔针对电容屏进行触摸操作时，所述主动式电容触摸笔通过笔尖在与电容屏接触的触摸接触点吸收电信 号，影响电容屏的电容变化，进而在电容屏产生触摸信号。
可以理解的是，所述主动式触摸物主要用于产生主动式信号，因此，由主动式触摸物触摸产生的被动式信号，是误差信号。
所述电容屏以一个既定触摸采样率对针对电容屏的触摸信号进行采样。
S102，当触摸操作为主动式触摸物产生时，接收主动式触摸物触摸产生的第一触摸信号；
S103，判断第一触摸信号是否是主动式信号，若是，则根据第一触摸信号确定电容屏的防误判区域；
其中，所述第一触摸信号是由主动式触摸物针对电容屏进行触摸操作在电容屏产生的触摸信号。
具体的，若所述第一触摸信号是由主动式触摸物触摸产生的主动式信号时，根据所述第一触摸信号确定所述电容屏的防误判区域。
所述防误判区域是指在此区域内仅可以对识别到的主动式信号进行输出的区域。此区域通常位于主动式触摸物与电容屏的触摸接触点附近，随着该触摸接触点的移动，该防误判区域也跟着移动。
所述第一触摸信号在电容屏上的具体表现可以是对应触摸区域的触摸感知参数发生变化，所述基于所述第一触摸信号确定所述防误判区域可以是基于触摸感知参数变化区域确定所述防误判区域，所述触摸感知参数变化区域位于所述防误判区域内。
所述触摸感知参数可以是触点电容值，例如一块电容屏包括多个电容感应单元，所述触摸感知参数即为每个电容感应单元的电容值，所述触摸感知参数变化区域是指对应一次触摸操作可以有多个电容感应单元的电容值发生变化，所述多个电容感应单元形成的区域即为触摸感知参数变化区域。
可选的，所述根据所述第一触摸信号确定所述电容屏的防误判区域可以是通过确定所述第一触摸信号对应的主动式触摸物的第一触摸接触点，然后以所述第一触摸接触点为圆心，以预设距离为半径所组成的圆形区域为所述电容屏的防误判区域。
可选的，所述预设距离不大于15厘米。
可选的，所述防误判区域还可以是矩形区域、三角型区域、梯形区域或其他任意形状的闭合区域，对此本申请实施例不做限定。
S104，接收主动式触摸物触摸产生的第二触摸信号，判断第二触摸信号是否是被动式信号，若是，判断被动式信号是否是在电容屏的防误判区域内产生，若是，则仅基于所述主动式触摸物触摸产生的主动式信号显示书写轨迹；
具体的，若所述第二触摸信号为被动式信号，即为主动式触摸物通过与电容屏接触的触摸接触点吸收电信号、影响电容屏的电容变化、而在电容屏产生的信号，则判断所述被动式信号是否是在所述电容屏的防误判区域内产生，若所述被动式信号在所述电容屏的防误判区域内产生，则忽略所述第二触摸信号，以使所述电容屏仅基于所述主动式触摸物触摸产生的主动式信号显示书写轨迹。
所述忽略所述第二触摸信号可以是提高防误判区域内被动式信号的信号识别阈值，以使得所述第二触摸信号不被识别；还可以是识别到所述第二触摸信号，在显示书写轨迹时，忽略所述第二触摸信号。
可以理解的是，由一个主动式触摸物针对电容屏进行触摸操作就产生了包括第一触摸信号以及第二触摸信号的两种触摸信号，这样会在电容屏留下相似的两条笔迹，即第一触摸信号对应的第一笔迹以及第二触摸信号对应的第二笔迹，其中第一笔迹为使用主动式触摸物书写的期望笔迹，第二笔迹为使用主动式触摸物书写时产生的误差笔迹。请参见图2，为本申请实施例提供了一种误差笔迹的举例示意图。如图2所示，所示为主动式电容触摸 笔针对电容屏进行的一次触摸操作而产生的两条笔迹，其中，所示实线为期望笔迹，所示虚线为误差笔迹。
在本申请实施例中，在接收到由主动式触摸物针对电容屏进行触摸操作在电容屏产生的第一触摸信号时，基于所述第一触摸信号形成防误判区域，若在防误判区域内接收到主动式触摸物在电容屏产生的第二触摸信号，忽略所述第二触摸信号，仅基于所述主动式触摸物触摸产生的主动式信号显示书写轨迹，以使得电容屏仅输出显示主动式触摸物书写的期望笔迹，避免输出显示主动式触摸物书写时产生的误差笔迹。
可选的，所述仅基于所述主动式触摸物触摸产生的主动式信号显示书写轨迹可以包括：判断所述主动式触摸物触摸产生的主动式信号的信号强度是否达到所述主动式信号的信号识别阈值；若所述主动式触摸物触摸产生的主动式信号的信号强度达到所述主动式信号的信号识别阈值，则根据所述主动式触摸物触摸产生的主动式信号显示书写轨迹；若所述主动式触摸物触摸产生的主动式信号的信号强度未达到所述主动式信号的信号识别阈值，则将所述主动式触摸物触摸产生的主动式信号判定为误触信号。
S105，随着主动式触摸物的移动，接收主动式触摸物触摸产生的第三触摸信号，若第三触摸信号为主动式信号，则根据第三触摸信号重新确定电容屏的防误判区域。
具体的，随着所述主动式触摸物的移动，实时接收所述主动式触摸物触摸产生的第三触摸信号，若所述第三触摸信号为所述主动式触摸物触摸产生的主动式信号，根据所述第三触摸信号重新确定所述电容屏的防误判区域。
不难理解，所述防误判区域不是一个位置固定不变的区域，而是随着主动式触摸物的移动，根据当前主动式触摸物触摸产生的触摸信号的位置实时改变的区域。在重新确定了电容屏的防误判区域后，可以根据重新确定的防误判区域对此时防误判区域内产生的被动式信号进行识别。
在本申请实施例中，通过扫描针对所述电容屏的触摸操作，在接收到主动式触摸物触摸产生的主动式信号时，确定一个跟随所述主动式触摸物的移动而动态移动的防误判区域，将防误判区域内接收到的所述主动式触摸物触摸产生的被动式信号忽略，以使得电容屏仅基于主动式触摸物触摸产生的主动式信号显示书写笔迹，避免将主动式触摸物触摸产生的被动式信号对应的书写笔迹进行显示，保证电容屏对触摸操作的识别精准度，改善显示效果，进而提升用户体验。
请参见图3，为本申请实施例提出了一种触摸操作的识别方法的流程示意图。如图3所示，所述触摸操作的识别方法可以包括以下步骤S201～步骤S209。
S201，扫描针对电容屏的触摸操作；
具体可参见另一实施例中步骤S101详细描述，此处不再赘述。
S202,当触摸操作为主动式触摸物产生时，接收主动式触摸物触摸产生的第一触摸信号；
具体可参见另一实施例中步骤S102详细描述，此处不再赘述。
S203,判断第一触摸信号是否是主动式信号，若是，则确定第一触摸信号对应的主动式触摸物的第一触摸接触点；
具体的，若所述第一触摸信号是由主动式触摸物触摸产生的主动式信号时，则确定所述第一触摸信号对应的主动式触摸物的第一触摸接触点，所述第一触摸接触点为所述主动式触摸物和电容屏的接触位置，可用基于电容屏的屏幕坐标系的坐标表示。
在一种可行实施方式中，电容屏的触摸检测部件检测到所述第一触摸信号，所述第一触摸信号对应于电容屏上一定区域内的触摸感知参数发生变化，所述电容屏的底层处理芯片接收触摸感知参数变化区域的信息，并在所述触摸感知参数变化区域内确定所述主动式 触摸物的第一触摸接触点的位置。
所述触摸感知参数可以是电容屏的触点电容值。
可以理解的是，所述触摸感知参数变化区域是电容屏上的一部分区域，它是没有特定形状和面积的。
进一步的，所述在所述触摸感知参数变化区域内确定所述主动式触摸物的第一触摸接触点位置，可以通过以下两种可行的实施方式。
一种可行的识别方式1：作所述触摸感知参数变化区域的最小覆盖圆，识别所述最小覆盖圆的圆心作为第一触摸接触点的位置。
一种可行的识别方式2：作所述触摸感知参数变化区域的最大内接圆，识别所述最大内接圆的圆心作为第一触摸接触点的位置。
请一并参见图4，为本申请实施例提供了一种确定第一触摸接触点的举例示意图。
如图4所示，以主动式电容触摸笔为例，所述主动式电容触摸笔简称主动笔。上述识别方式1：当主动笔对电容屏进行触摸操作时，电容屏的触摸检测部件检测到触摸感知参数变化区域1，并将触摸感知参数变化区域信息传送给电容屏底层处理芯片，电容屏底层处理芯片识别所述触摸感知变化区域的最小覆盖圆的圆心M点坐标，确定M点坐标为第一触摸接触点。上述识别方式2：当主动笔对电容屏进行触摸操作时，电容屏的触摸检测部件检测到触摸感知参数变化区域2，并将触摸感知参数变化区域信息传送给电容屏底层处理芯片，电容屏底层处理芯片识别所述触摸感知变化区域的最大内接圆的圆心N点坐标，确定N点坐标为第一触摸接触点。
S204，以第一触摸接触点为圆心，以预设距离为半径所组成的圆形区域为电容屏的防误判区域；
可选的，所述预设距离不大于15厘米。
在同时使用主动式触摸物和被动式触摸物进行书写时，由主动式触摸物针对电容屏的触摸操作产生的主动式信号会形成防误判区域，为避免所述防误判区域对被动式触摸物针对电容屏的触摸操作产生的被动式信号产生影响，根据大部分用户的肩宽，将以所述第一触摸接触点为圆心，以预设距离为半径所组成的圆形区域中的预设距离设置为不大于15厘米作为本申请实施例提出的优选预设距离。所述预设距离具体值可以根据实际使用习惯自行设定。
请一并参见图5，为本申请实施例提供了一种确定防误判区域的举例示意图。
如图5所示，以所示主动笔的第一触摸接触点为圆心，以0.5cm为半径作圆型区域，所示圆形区域即为所述防误判区域。
S205，接收主动式触摸物触摸产生的第二触摸信号，判断第二触摸信号是否是被动式信号，若是，判断被动式信号是否是在电容屏的防误判区域内产生，若是，则判断所述主动式触摸物触摸产生的主动式信号的信号强度是否达到主动式信号的信号识别阈值；
S206，若所述主动式触摸物触摸产生的主动式信号的信号强度达到主动式信号的信号识别阈值，则根据所述主动式触摸物触摸产生的主动式信号显示书写笔迹；
S207，若所述主动式触摸物触摸产生的主动式信号的信号强度未达到主动式信号的信号识别阈值，则将所述主动式触摸物触摸产生的主动式信号判定为误触信号；
其中所述主动式信号的信号识别阈值用于判断主动式信号是否可以被输出，即在本实施例中，若主动式信号的信号强度大于或等于所述主动式信号的信号识别阈值，则可以基于所述主动式信号显示书写笔迹，若主动式信号的信号强度小于所述主动式信号的信号识别阈值，则将所述主动式信号判定为误触信号或杂讯。所述信号识别阈值可以是由触摸操作引起的某一个量的变化程度。例如，若所述主动式信号的初始识别阈值为50单位，某一刻施加在电容屏的主动式信号为60单位，则所述主动式信号大于所述主动式信号的初始识 别阈值，所述电容屏可以显示所述主动式信号产生的书写笔迹；若所述被动式触摸物触摸信号为40单位，则不显示所述主动式信号产生的书写笔迹。
所述第二触摸信号为主动式触摸物通过与电容屏接触的触摸接触点吸收电信号影响电容屏的电容变化而在电容屏产生的被动式信号时，若不对所述第二触摸信号进行处理，则电容屏会输出显示如图2所示的包括所述主动式触摸物触摸产生的主动式信号对应的期望笔迹以及所述主动式触摸物触摸产生的被动式信号对应的误差笔迹的显示效果，显示效果极为不佳，而通过基于第一触摸信号确定如图5所示的防误判区域后，会将第二触摸信号忽略，电容屏仅基于所述主动式触摸物触摸产生的主动式信号显示如图6所示的仅包括期望笔迹的显示效果。
S208，随着主动式触摸物的移动，接收主动式触摸物触摸产生的第三触摸信号，若第三触摸信号为主动式信号，则确定第三触摸信号对应的主动式触摸物的第二触摸接触点；
S209，以第二触摸接触点为圆心，以预设距离为半径所组成的圆形区域为重新确定的电容屏的防误判区域。
可以理解的是，所述防误判区域不是位置固定不变的，防误判区域是随着主动式触摸物的移动而时刻改变的。随着主动式触摸物的移动，实时接收主动式触摸物触摸产生的第三触摸信号，确定以第三触摸信号对应的主动式触摸物的第二触摸接触点为圆心，以预设距离为半径所组成的圆形区域作为重新确定的所述电容屏的防误判区域。即，防误判区域是时刻随着主动式触摸物与电容屏的触摸接触点的移动而移动的区域。
请参见图7，为本申请实施例提供了一种防误判区域的举例示意图。如图7所示，在使用主动式电容触摸笔绘制所示笔迹曲线的过程中，所示主动式电容触摸笔位于不同位置，对应的防误判区域是不同的，如图所示，当所示主动式电容触摸笔位于第一位置时，此时的防误判区域为所示防误判区域1，当所示主动式电容触摸笔位于第二位置时，此时的防误判区域为所示防误判区域2。
在本申请实施例中，通过扫描针对所述电容屏的触摸操作，在接收到主动式触摸物触摸产生的主动式信号时，确定一个跟随所述主动式触摸物的移动而动态移动的防误判区域，将防误判区域内接收到的所述主动式触摸物触摸产生的被动式信号忽略，以使得电容屏仅基于主动式触摸物触摸产生的主动式信号显示书写笔迹，避免将主动式触摸物触摸产生的被动式信号对应的书写笔迹进行显示，保证电容屏对触摸操作的识别精准度，改善显示效果，进而提升用户体验。
请参见图8，为本申请实施例提出了一种触摸操作的识别方法的流程示意图。如图8所示，所述触摸操作的识别方法可以包括以下步骤S301～步骤S306。
S301，扫描针对电容屏的触摸操作；
具体可参见另一实施例中步骤S101详细描述，此处不再赘述。
S302,当触摸操作为主动式触摸物产生时，接收主动式触摸物触摸产生的第一触摸信号；
具体可参见另一实施例中步骤S102详细描述，此处不再赘述。
S303,判断第一触摸信号是否是主动式信号，若是，则根据第一触摸信号确定电容屏的防误判区域；
具体可参见另一实施例中步骤S103详细描述，此处不再赘述。
S304,接收被动式触摸物触摸产生的第四触摸信号，若第四触摸信号为被动式信号，判断被动式信号是否是在电容屏的防误判区域内产生；
S305，若被动式信号在电容屏的防误判区域内产生，则仅基于所述主动式触摸物触摸产生的主动式信号显示书写轨迹；
在同时使用主动式触摸物和被动式触摸物进行书写的情况下，基于主动式触摸物针对电容屏的触摸操作产生第一触摸信号，并根据第一触摸信号确定防误判区域之后，接收被动式触摸物针对电容屏的触摸操作产生的第四触摸信号，并判断第四触摸信号是不是在电容屏的防误判区域内产生，若第四触摸信号是在所述电容屏的防误判区域内，则忽略所述第四触摸信号，仅基于所述主动式触摸物触摸产生的主动式信号显示书写轨迹。
