为使本申请实施例的目的、技术方案和优点更加清楚，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清楚、完整地描述，显然，所描述的实施例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作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。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例，例如能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
随着智能设备中的普及，其中，笔记本电脑、平板电脑等终端设备因其具有极好的可移动性、便携性，受到用户的广泛青睐。在使用终端设备中的触控屏或触摸板的过程中，可能会存在较高频次的手掌误触行为，影响用户的正常使用。触摸板和触控屏通常采用电阻式、电容式、红外线式以及表面声波式等，本发明实施例对触摸板和触控屏的工作原理不做限制，下面以电容式触摸板为例，对其工作原理进行介绍，图1是本申请提供的一种电容式 触摸板的工作原理示意图，如图1所示，触摸板中包含了驱动通道Y和感应通道X，在检测手指触摸时，由触摸控制器控制驱动电路输出驱动信号到驱动通道Y，驱动信号通过驱动通道Y与感应通道X之间的电容耦合到感应通道X上，然后由感应电路检测感应通道X中的信号变化，并通过检测信号的变化量来计算手指的当前触摸位置。

以下，对本申请实施例的示例性应用场景进行介绍。
本申请实施例可以应用在包括触摸板或触控屏的终端设备中，例如笔记本电脑、平板电脑、移动终端、医疗设备等，本发明实施例对终端设备的类型不做限制。
应用场景1
以笔记本电脑的应用为例，图2是本申请实施例一示例性应用场景图，如图2所示，用户在使用笔记本电脑的过程中，图2为示例性打字的姿势，用户在实际使用中也可能会双手或单手放置在触摸板11上，本发明对此不做限制。用户在使用键盘12的过程中，大部分时刻均与触摸板11有接触，由于双手一直需要敲击键盘12上的按键，手与触摸板11的接触面积、接触位置也时刻在发生变化，然而，手掌稳定放置在触摸板11上时，手掌与触摸板11的位置关系相对稳定。
应用场景2
以平板电脑的应用为例，图3是本申请实施例另一示例性应用场景图，如图3所示，用户在使用平板电脑13的过程中，或在用户拿起或放下平板电脑时，可能会用手触摸平板电脑13的触控屏，造成手掌误触，以影响用户对平板电脑的正常使用。
基于上述应用场景，下面对本申请技术方案进行详细介绍：
图4是本申请一实施例提供的识别手掌误触的方法的流程图，其中，该 方法可以由识别手掌误触的装置执行，该装置可以通过软件和/或硬件的方式实现，例如：该装置可以是上述终端设备的部分或全部，下面以上述终端设备中的芯片为执行主体，对识别手掌误触的方法进行说明，如图4所示，该方法包括如下步骤：
步骤S101：在触控面上的N个触摸点中，获取每个触摸点在触控面上的接触面积和位置，其中N为大于等于1的整数，触控面为触摸板或触控屏。
触控面是可以通过触控操作的装置，可以是触摸板或者是触控屏，其中，触摸板是一种在平滑的触控板上，利用手指的滑动操作来移动游标的输入装置，广泛应用于笔记本电脑中，也应用于一些便携式设备上，如个人数码助理、便捷式影音设备等，本发明实施例对触摸板的结构、类型以及应用设备等不做限制。另外，触控屏是一种可接收触头等输入讯号的感应式液晶显示装置，当接触了屏幕上的图形按钮时，屏幕上的触觉反馈系统可根据预先编程的程式驱动各种连结装置，广泛应用于各种智能设备中，本发明实施例对触摸屏的结构、类型以及应用设备等不做限制。
当触摸触控面时，根据不同的触摸方式，可能会在触控面上存在一个或多个触摸点，芯片在触控面上的N个触摸点中，获取每个触摸点在触控面上的接触面积和每个触控点在触控面上的位置，其中，N为大于等于1的整数。
骤S102：根据每个触摸点在触控面上的接触面积和位置，判断任意一个触摸点或任意多个触摸点是否符合预设手掌模型。
预设手掌模型可以根据不同的终端设备或不同的触控面进行建立，本发明实施例对预设手掌模型的具体模型不做限制，在一种可能的实施方式中，在根据每个触摸点在触控面上的面积和位置，判断任意一个触摸点或任意多个触摸点是否符合预设手掌模型之前，还包括：
建立预设手掌模型，预设手掌模型包括单手掌模型、单手掌单手指模型、双手掌模型和双手掌双手指模型。
其中，单手掌模型是只有一只手掌接触触控面的模型，单手掌单手指模型为有一只手的手掌和手指接触触控面的模型，双手掌模型是两只手的手掌同时接触触控面的模型，双手掌双手指模型是两只手的手掌和手指同时接触触控面的模型。
在获取每个接触点在触控面上的接触面积和位置之后，根据每个接触点 在触控面上的接触面积和位置，以及建立的预设手掌模型，判断任意一个触摸点或任意多个触摸点是否符合预设手掌模型，本申请实施例对如何判断任意一个触摸点或任意多个触摸点是否符合预设手掌模型的具体实施方式不做限制。
步骤S103：若存在触摸点符合预设手掌模型，则确定触摸点为手掌误触。
经过判断，若存在触摸点符合预设手掌模型，则确定触摸点为手掌误触，示例性的，若存在一个触摸点符合单手掌模型，则该触摸点为手掌误触，若存在两个触摸点符合单手掌单手指模型或双手掌模型，则判断该两个触摸点为手掌误触，若存在四个触摸点符合双手掌双手指模型，则判断该四个触摸点为手掌误触。若判断一个或多个触摸点为手掌误触，则可以通过标记该触摸点为误触，并且芯片不执行在正常情况下该接触点需要执行的操作，进而避免了由于手掌误触影响用户正常使用终端设备的情形。
本方案中，通过根据每个触摸点在触控面上的接触面积和位置，判断任意一个触摸点或任意多个触摸点是否符合预设手掌模型，实现了判断当前对触控面的触摸操作是否为手掌误触，并且节约了生产成本。
为了实现判断任意一个触摸点或任意多个触摸点是否符合预设手掌模型，可以根据触控面上触摸点的个数，选择不同的判断策略，在一种可能的实施方式中，图5A-5C是本申请另一实施例提供的识别手掌误触的方法的流程图，其中，该方法可以由识别手掌误触的装置执行，该装置可以通过软件和/或硬件的方式实现，例如：该装置可以是上述终端设备的部分或全部，下面以上述终端设备中的芯片为执行主体，对识别手掌误触的方法进行说明，如图5A所示，若触控面上存在一个触摸点，上述实施例中的步骤S102可以包括：
步骤S201：若触控面上存在一个触摸点，则判断触摸点是否符合单手掌模型。
若触控面上存在一个触摸点，则根据该触摸点在触控面上的面积和位置，判断触摸点是否符合单手掌模型，若该触摸点符合单手掌模型，则判断该触摸点为手掌误触，若该触摸点不符合单手掌模型，则判断给触摸点为用户正常触摸操作。
在实际操作中，触控面上可能存在不止一个触摸点，可选的，如图5B所 示，若触控面上存在两个或三个触摸点，则上述实施例中的步骤S102可以包括：
步骤S202：若触控面上存在两个或三个触摸点，则判断触摸点是否符合单手掌模型、单手掌单手指模型和双手掌模型中的至少一项。
若触控面上存在两个或三个触摸点，则可以通过判断任意一个触控点是否符合单手掌模型，或者判断任意两个触摸点是否符合单手掌单手指模型或者双手掌模型，本发明实施例对判断触摸点是否符合单手掌模型、单手掌单手指模型和双手掌模型的顺序不做限制。
另外，本发明实施例对判断触摸点是否符合单手掌模型、单手掌单手指模型和双手掌模型中的模型个数也不做限制，例如，触控面上存在两个触摸点，若判断该两个触摸点为单手掌单手指模型，则可以不再判断该两个触摸点是否符合双手掌模型中的模型，也可以不再判断该两个任意触摸点是否符合单手掌模型。
可选的，若触控面上存在四个及以上的触摸点，如图5C所示，则上述实施例中的步骤S102可以包括：
步骤S203：若触控面上存在四个及以上的触摸点，则判断触摸点是否符合单手掌模型、单手掌单手指模型、双手掌模型和双手掌双手指模型中的至少一项。
若触控面上存在四个及以上的触摸点，则可以判断任意一个触摸点是否符合单手掌模型，判断任意两个触摸点是否符合单手掌单手指模型或双手掌模型，判断任意四个接触点是否符合双手掌双手指模型，本发明实施例对判断触摸点是否符合单手掌模型、单手掌单手指模型、双手掌模型和双手掌双手指模型的顺序不做限制。例如，该触控屏上存在四个触摸点，则可以选择首先判断该四个触摸点是否双手掌双手指模型，然后判断该四个触摸点中的任意两个触摸点是否符合单手掌单手指模型或双手掌模型，最后判断该四个触摸点中的任意一个触摸点是否符合单手掌模型。另外，本发明实施例对判断触摸点是否符合单手掌模型、单手掌单手指模型、双手掌模型和双手掌双手指模型的个数也不做限制，例如，触控屏上存在四个触摸点，则可以同时判断任意一个触摸点是否符合单手掌模型，判断任意两个触摸点是否符合单手掌单手指模型或双手掌模型，判断任意四个接触点是否符合双手掌双手指 模型，也可以首先判断该四个触摸点是否符合双手掌双手指模型，若经过判断，该四个触摸点符合双手掌双手指模型，则，可以不再判断该四个触摸点是否符合单手掌模型、单手掌单手指模型以及双手掌模型。
本方案中，根据触控面上触控点的个数，选择需要匹配的预设手掌模型，提高了判断当前对触控面的触摸操作是否为手掌误触的准确率。
