Description
本发明实施例涉及通信领域,尤其涉及通信领域中识别误触摸操作的方法和电子设备。
随着手机等电子设备的发展,电子设备的触摸屏的边框被设计的越来越窄,甚至设计成无边框的电子设备。窄边框或者无边框的电子设备给用户带来了很好的触摸体验和显示效果,但是用户在实际操作的过程中容易发生误触,例如单手握手机时,手指对触摸屏进行触摸的同时,虎口或手掌也可能在触摸屏上触摸,这样会引起误操作,使得用户体验较差。
为了识别误触(Palm Rejection),一般都是将触摸屏划分为边缘区域和中心区域,通过触摸操作所在的区域来确定触摸是否是误触摸,例如,通过设定触摸分界线,当在触摸屏的中心区域有触摸操作时,将触摸屏边缘与触摸分界线之间的触摸操作的识别为误触摸操作,当触摸屏中心没有触摸操作时,将触摸屏边缘与触摸分界线之间的触摸操作识别为有效触摸操作。又例如,如图4所示,通过设定第一触摸分界线为A1线和A2线,第二触摸分界线为B1线和B2线,当触摸操作在触摸屏边缘与第一触摸分界线之间时,将触摸操作识别为误触摸操作;当触摸屏中心没有触摸操作,而在第一触摸分界线与第二触摸分界线之间有触摸操作时,将触摸操作识别为有效触摸操作;当触摸中心B1到B2区域有触摸操作,将第二触摸分界线与触摸屏边缘的之间所有的触摸操作的都识别为误触摸操作。但是这两种识别触摸的方式,在中心区域没有触摸操作时,当边缘区域有误触摸操作时,仍然将边缘误触摸操作识别为有效触摸操作;或者是在中心区域有触摸操作的同时,边缘区域也有有效触摸操作,会将边缘有效触摸操作的识别为误触摸操作,这样,会使得用户体验较差。

似手指形状的椭圆的长半轴和短半轴范围,当检测到触摸操作时,可以判断该触摸操作的坐标集合组成的椭圆形状的长半轴和短半轴是否在第一形状类型的长半轴和短半轴的范围内,若在可以将该触摸操作确定为有效触摸操作,若不在可以将该触摸操作确定为误触摸操作;可选地,也可以确定一个预设形状集合,若检测到触摸操作的形状属于预设形状集合,可以将该触摸操作确定为有效触摸操作,否则确定为误触摸操作;可选地,也可以将触摸操作的形状与预设形状集合中的形状进行匹配度的计算,将匹配度大于设定匹配阈值的触摸操作确定为有效触摸操作,将匹配度小于设定阈值的触摸操作确定为误触摸操作,即若触摸操作的形状是近似接近形状集合中的形状也可以将触摸操作确定为有效触摸操作。本发明实施例对触摸操作的形状与预设的形状如何匹配并不作限定。
可选地,一个触摸点对应一个电容值,至少一个电容值对应一个坐标点。
作为一个可选实施例,在确定该至少一个触摸点在该电容触摸屏上的第一坐标集合之后,该方法100还包括:当该第一坐标集合组成区域的形状的面积大于第一阈值时,将该触摸操作确定为误触摸操作,该第一阈值为该第一形状类型的形状的面积的最大值。
具体地,若检测触摸操作的形状为第一形状,首先确定该第一形状是否属于第一形状类型,若确定该第一形状是第一形状类型,进一步地,可以确定该第一形状的面积是否小于设定的第一阈值,若该第一形状的面积小于设定的第一阈值,则可以将该触摸操作确定为有效触摸操作;若该第一形状的而面积大于设定的第一阈值,则可以将该触摸操作确定误触摸操作,即可以通过确定第一形状是否属于第一形状类型,判断该触摸操作是有效触摸操作还是误触摸操作,也可以通过当该第一形状属于第一形状类型时,进一步判断该第一形状的面积是否大于设定的第一阈值来确定该触摸操作是有效触摸操作还是误触摸操作,进一步提高识别触摸操作的准备性,提高用户体验。可选地,也可以仅通过判断第一形状的面积大小来确定该触摸操作是否是误触摸操作;可选地,也可以先判断第一形状的面积大小再判断该第一形状是否属于第一形状类型来确定该触摸操是否是误触摸操作,即本发明实施例可以采用形状判断触摸操作,也可以采用面积判断触摸操作,也可以先采用形状判断后采用面积判断触摸操作,也可以先采用面积判断后采用形状判断,本发明实施例对此不作限制。
作为一个例子,第一形状类型的形状是手指的形状,第一形状类型中所有手指形状的面积的最大值为144mm2,当检测到一个虎口或手掌的触摸操作对应的触摸点在电容触摸屏上坐标集合组成的区域的形状近似接近第一形状类型的形状,可以进一步检测虎口或手掌的触摸操作的形状的面积,例如为180mm2,180大于144,则可以确定该触摸操作是误触摸操作,即可能在首次判断出现误判时,选择面积作为进一步的判断条件。可选地,可以设定第一形状类型的形状的面积区间范围[100mm2,144mm2],当检测到触摸操作对应的触摸点在电容触摸屏上的坐标集合组成区域的形状的面积在该区间范围时,可以将该触摸操作确定为有效触摸操作,否则确定为误触摸操作。
作为一个可选实施例,在确定该至少一个触摸点在该电容触摸屏上的第一坐标集合之后,该方法100还包括:当该第一坐标集合组成区域的形状属于该第一形状类型时,在第一时间段之后,获取该电容触摸屏上触摸点的电容值超过该预设阈值的第二坐标集合;当该第二坐标集合组成区域的形状不属于该第一形状类型时,将该触摸操作确定为该误触摸操作。
具体地,若检测到电容触摸屏上的触摸操作,根据该触摸操作的形状第一将该触摸操作判断为有效触摸操作,则在第一次检测到的触摸操作的坐标集合可能并不是该触摸操作的真实坐标,可以在设定的第一时间段之后,例如该设定的周期可以10ms,继续检测该触摸操作的坐标集合组成的区域的面积,进一步确定该触摸操作是否是误触摸操作,第一次检测到该触摸操作的坐标集合组成的区域的形状属于第一形状类型,在第一时间段之后继续检测该触摸操作的坐标集合组成的区域的形状是否是第一形状类型,若是,则判断该触摸操作是有效触摸操作,若否,则认为将第一次的误触摸操作判断为有效触摸操作,进一步地,将该触摸操作确定为误触摸操作,纠正了第一次的误判断,进一步提高判断触摸操作的准确性,提高了用户体验。
作为一个例子,如图2(a)和图2(b)所示,若触摸操作是手掌的触摸操作,在第一时刻检测到电容触摸屏上的电容值的变化如图2(a)所示,图2(a)中电容变化大于预设阈值的电容为最左侧一列的四个电容值,该四个电容值对应的坐标组成的区域的形状接近与手指的形状,如该第一形状类型为手指的形状,则在第一时刻会将该触摸操作判断为有效触摸操作,在第二时刻,检测该触摸操作的电容值变化超过阈值的为:如图2(b)的灰色部分,则判断图
2(b)中灰色部分组成的区域的形状不属于手指的形状,将该操作确定为误触摸操作,该第一时间段可以为第一时刻到第二时刻的时间间隔。
作为一个可选实施例,该电容触摸屏包括边缘区域和中心区域,其中,该当检测到该电容触摸屏上的至少一个触摸点的电容值大于预设阈值时,确定该电容触摸屏上有触摸操作,包括:当检测到该边缘区域的该至少一个触摸点的电容值大于该预设阈值时,确定该边缘区域有触摸操作。
具体地,由于在电容触摸屏的边缘可能会频繁的发生误触摸,可以根据用户的操作习惯将电容触摸屏分为边缘区域和中心区域,针对电容触摸屏的边缘区域可以采用方法100的对误触摸操作进行识别,进一步提高了用户体验。
作为一个可选的实施例,该第一形状类型为手指形状的类型。
具体地,手指的形状可以为近似椭圆形状或者近似圆形的形状,或者可以采集大量手指的形状来确定手指的形状类型,且不同的用户可以确定不同的手指形状,如对于男性专用的电子设备可以确定针对男性手指类型,对于女性专用的电子设备可以确定针对女性的手指类型。
应理解,上述各过程的序号的大小并不意味着执行顺序的先后,各过程的执行顺序应以其功能和内在逻辑确定,而不应对本发明实施例的实施过程构成任何限定。
图3示出了本发明实施例的识别误触摸操作的方法200示意图,该方法200应用于具有触摸屏的电子设备,该触摸屏包括中心区域和边缘区域,该触摸屏可以是电容触摸屏也可以是压力触摸屏,也可以是其他的触摸屏,本发明实施例对此不作限制,该方法可以由电子设备执行,该方法200可以包括:
S210,当检测到第一触摸操作时,检测该中心区域是否存在第二触摸操作,该第一触摸操作对应的至少一个第一触摸点位于该边缘区域;
S220,若该中心区域存在该第二触摸操作,将该第一触摸操作确定为误触摸操作;
S230,在将该第一触摸操作确定为误触摸操作之后,若该第一触摸操作仍存在并且检测不到该中心区域存在该第二触摸操作,将该第一触摸操作继续确定为该误触摸操作。
具体而言,当电子设备检测到边缘区域有第一触摸操作时,检测中心区
域是否有第二触摸操作,当中心区域有第二触摸操作时,将边缘区域的第一触摸操作确定为误触摸操作,由于触摸操作的触摸时长不统一,当中心区域没有第二触摸操作时,而边缘区域仍有第一触摸操作,则此时第一触摸操作仍然还会被判断为误触摸操作,即只要第一次被判断为误触摸操作之后,不管中心区域有没有触摸操作,边缘区域的触摸操作都认为是误触摸操作,避免了现有技术边缘区域被识别为误触摸操作之后,若中心区域没有触摸操作,则边缘区域的误触摸操作也会为当作有效触摸操作来输出,这样,本发明实施例可以避免误触摸操作当作有效触摸操作输出,提高用户体验。
例如,该方法200可以应用于这样的场景,当边缘区域存在一个虎口的误触摸操作,而中心区域也存在一个手指的有效触摸操作,由于虎口的触摸操作是用户无意识的触摸可能会触摸比较长的时间,而用户也不会意识到虎口在触摸屏上的触摸,当中心区域的手指有效触摸操作消失后,虎口的触摸操作仍然抑制上报,即当一个触摸操作在第一次被识别为误触摸操作之后,即使中心区域的有效触摸操作消失之后,该触摸操作仍然被抑制上报。
例如,如图4所示的触摸屏,触摸屏边缘线为A1线和A2线,边缘区域和中心区域的分割线为B1线和B2线,则边缘区域为A1线到B1线的区域和/或A2线到B2线的区域,中心区域为B1线到B2线的区域,A1线到B1线的区域或A2线到B2线的区域有第一触摸操作时,检测B1线到B2线的区域是否有第二触摸操作,当B1线到B2线的区域有第二触摸操作时,A1线到B1线的区域或A2线到B2线的区域的第一触摸操作被识别为误触摸操作,在第一触摸操作被识别为误触摸操作之后,当B1线到B2线的区域没有触摸操作时,第一触摸操作仍然被认为是误触摸操作,抑制该第一触摸操作的输出,即只要首次被识别为误触摸操作后,只要该触摸操作在边缘区域,则该触摸操作一直被识别为误触摸操作。
应理解,第一触摸操作对应触摸屏上的多个触摸点,当S210中的至少一个第一触摸点可以为该多个触摸点,即在步骤S210,S220,S230中,该第一触摸操作对应的至少一个第一触摸点在边缘区域,如图4中的A1线到B1线的区域和/或A2线到B2线的区域。
作为一个可选实施例,在将该第一触摸操作继续确定为该误触摸操作之后,该方法200还包括:检测该第一触摸操作对应的至少一个第二触摸点和该至少一个第一触摸点形成的第一轨迹,该第一触摸操作对应多个触摸点,
该多个触摸点包括该至少一个第一触摸点和该至少一个第二触摸点,该至少一个第二触摸点位于该中心区域;若该第一轨迹的方向是从该边缘区域到该中心区域,则将该第一触摸操作确定为有效触摸操作。
具体而言,若第一触摸操作被确定为误触摸操作之后,若该第一触摸操作的轨迹是从边缘区域到中心区域的,即只要该第一触摸操作的有触摸点跨过边缘区域落在中心区域,则该第一误触摸操作可以被恢复为有效触摸操作,通过检测触摸操作的轨迹确定该触摸操作是否是用户的真实触摸操作,不只是检测当前触摸点的位置判断,提高了识别触摸操作的准确性。可选地,可以设定误触摸恢复线,误触摸恢复线在中心区域,如为图5中的C1线和C2线,即只要该第一触摸操作的触摸点跨过C1线或C2线就会将该第一触摸操作恢复为有效触摸操作,在图5中,C1线可以与B1线重合,也可以不重合,C2线可以与B2线重合,也可以不重合,本发明实施例对此不作限制。作为一个例子,如图5所示,假设该第一触摸操作对应的第一轨迹为a到b到c这一段,即至少一个第一触摸点为a到b这一段上的触摸点,至少一个第二触摸点为b到c这一段上的触摸点,第一轨迹为a到b到c的方向为边缘区域到中心区域,则将该触摸操作确定为有效触摸操作。
作为一个可选实施例,在该若该第一轨迹的方向是从该边缘区域到该中心区域,则将该第一触摸操作确定为有效触摸操作之后,该方法200还包括:检测该第一触摸操作对应的至少一个第三触摸点和该至少一个第二触摸点的形成的第二轨迹,该多个触摸点包括该至少一个第三触摸点,该至少一个第三触摸点位于该边缘区域,该至少一个第一触摸点与该至少一个第三触摸点中的触摸点至少一个不相同;若该第二轨迹的方向是从该中心区域到该边缘区域,则将该第一触摸操作确定为该有效触摸操作。
具体而言,若第一触摸操作的轨迹跨过边缘区域到中心区域再回到边缘区域时,即使开始被确定为误触摸操作,只要该第一触摸操作的轨迹到中心区域,当该第一触摸操作的轨迹再回到边缘区域时,就不再会被识别为误触摸操作了,而是会被识别为有效触摸操作。例如,如图5所示,假设该第一触摸操作对应的轨迹为第一轨迹和第二轨迹,第一轨迹为a到b到c这一段,第二轨迹为c到d到e这一段,即至少一个第一触摸点为a到b这一段上的触摸点,至少一个第二触摸点为b到c到d这一段上的触摸点,至少一个第三触摸点为d到e这一段上的触摸点,第一轨迹为a到b到c的方向为边缘
区域到中心区域,第二轨迹的方向为中心区域到边缘中心区域,则将该触摸操作确定为有效触摸操作。
作为一个可选实施例,该边缘区域包括:直接抑制上报区域,该直接抑制上报区域靠近该触摸屏的边缘;当检测到第一触摸操作时,检测该中心区域是否存在第二触摸操作之前,该方法200还包括:检测该多个触摸点是否在该直接抑制上报区域;若该多个触摸点在该直接抑制上报区域,则将该第一触摸操作确定为该误触摸操作。
具体地,若第一触摸操作对应的多个触摸点落在直接抑制上报区域,则无论中心区域是否有触摸操作,都将落在直接抑制上报区域的触摸操作当作误触摸操作;当第一触摸操作对应一段轨迹,当该轨迹的前半段落在直接抑制上报区域时可以将该第一触摸操作被识别为误触摸操作时,当检测到该轨迹的后半段落在跨过边缘区域落到中心区域,则将该第一触摸操作确定为有效触摸操作;可选地,若第一触摸操作的轨迹从直接抑制上报区域跨过边缘区域到中心区域再回到直接抑制上报区域,也将该第一触摸操作确定为有效触摸操作。
作为一个例子,如图6所示,假设A1线到D1线的区域和/或A2线到D2线的区域为直接抑制上报区域,该第一触摸操作对应的多个触摸点落在A1线到D1线或A2线到D2线的区域,则直接将该第一触摸操作确定为误触摸操作;若该第一触摸对应的触摸点形成的轨迹为第一轨迹和第二轨迹,第一轨迹为a到b这一段,第二轨迹为b到c这一段,则当检测到第二轨迹时,则将该第一触摸操作确定为有效触摸操作;若该第一触摸对应的触摸点形成的轨迹为第一轨迹和第二轨迹,第一轨迹为a到b到c这一段,第二轨迹为c到d到e这一段,则将该第一触摸操作确定为有效触摸操作。
作为一个可选实施例,在该将该第一触摸操作继续确定为该误触摸操作之后,该方法200还包括:根据该至少一个第一触摸点确定第一区域,该边缘区域包括该第一区域和第二区域;当检测到该第一区域存在第三触摸操作时,将该第三触摸操作确定为该误触摸操作。
具体地,采用S210,S220,S230确定误触摸操作之后,可以根据该误触摸操作的触摸点确定一个第一区域,当以后有触摸操作出现在该第一区域后,则将该触摸操作直接确定为误触摸操作,例如,该误触摸操作的触摸点对应多个坐标点,可以选择多个坐标点中的一个坐标点为中心,10个像素为
宽,20个像素为长组成的矩形确定为该第一区域;也可以通过对多个坐标点进行分析得到中心点和半径,确定一个圆形的第一区域;也可以确定一个椭圆形的第一区域,本发明实施例对第一区域时如何确定的并不作限制,该第一区域在设备刚上电时不存在,是在有误触摸操作发生时,可以根据发生的误触摸操作的坐标建立该第一区域。如图7该E1区域或E2区域可以为该第一区域,第二区域可以为A1线到B1线区域和A2线区域到B2线区域除了E1区域和E2区域的以外的区域,并且可以为该第一区域设定抑制恢复线F1线或F2线,当在E1或E2区域的第一触摸操作被确定误触摸操作之后,当检测到该触摸操作的触摸点跨过F1线或F2线时,则将该第一触摸操作确定为有效触摸操作,F线可以动态调整,当E1区域的存在触摸并且被确定为误触摸操作之后,F1线或F2线可以随着时间推移而与边缘的距离进行逐步增加(比如每10ms增加1个像素点),用于防止虎口碰在屏幕边缘,而人手大拇指又突然向屏幕中间区域操作时,虎口会进一步触碰到中心区域而引起误触。F1线或F2线可以与图6中的C1线或C2线重合,也可以与C1线或C2线不重合,本发明实施例对此不作限制。
例如,当根据历史的触摸操作确定E1区域或E2区域之后,任何触摸操作落在E1区域或E2区域都会被确定为误触摸操作,但是当一个手指的有效触摸操作的坐标在该E1区域或E2区域时,当检测到该手指的有效触摸操作的轨迹跨过F1线或F2线时,该触摸操作就被认为是一个有效的触摸操作。
作为一个可选实施例,在将该第一触摸操作继续确定为该误触摸操作之后,该方法200还包括:当该多个触摸点在该第二区域,并且检测到该第一触摸操作对应的触摸点从第三触摸点竖直滑动到第四触摸点时,将该第四触摸点对应的第四触摸操作确定为有效触摸操作,该多个触摸点包括该第三触摸点,该第四触摸点在该第二区域。
具体地,当第一触摸操作被识别为误触摸操作之后,会抑制该误触摸操作的输出,若产生向上或向下的滑动时,退出抑制状态,例如,向上滑动30像素点,或向下滑动10像素点后退出抑制,这样是为了保证用户在屏幕边缘上下滑动时不被一直抑制,且退出抑制后,输出触摸点所在的操作的信息。可选地,第一触摸操作可以是从第三触摸点到第四触摸点的一个滑动操作,当在该第一触摸操作在第三触摸点被抑制后,滑到该第四触摸点时,输出该第四触摸点对应的触摸操作,即该第四触摸操作可以是该第一触摸操作的一
部分;可选地,该第四触摸操作可以与该第一触摸操作没联系,只是一个触摸点的操作。
作为一个可选实施例,该边缘区域包括:第三区域,该第三区域包括该第一区域,该第三区域为用户单手握持该电子设备时,该用户的虎口位置接触到的该电子设备的位置。
具体地,第三区域可以为电子设备正向手持时长边对应的下半边缘区域,例如为图6中的O线将触摸屏分为上下两个区域,该第三区域为下半区域,并且电子设备的左右边缘的第一区域可以不同,也可以相同,具体根据用户的操作习惯确定,这样,根据用户的手持习惯确定相应的第一区域,进一步能够提高误识别操作的准确性。应理解,可以根据不同形状不同大小的电子设备设定第一区域和第二区域,例如手机的第二区域可以根据手机的触摸屏大小设定,平板电脑的第二区域可以根据平板电脑的触摸屏大小设定,手机和平板电脑的第二区域可以不相同。
作为一个可选的实施例,该边缘区域包括上边缘区域、下边缘区域、左边缘区域和右边缘区域的至少一种,即不仅可以确定触摸屏左右边缘的误触摸操作,也可以确定触摸屏上下边缘的误触摸操作,如图6所示,上下方向的H1线和H2线相当于左右方向的B1线和B2线,上下方向的J1线和J2线相当于左右方向的C1线和C2线,为了避免赘述,对采用H1线、H2线J1线和J2线确定误触摸操作不作详细的介绍,具体过程与B1线、B2线、C1线和C2线的原理类似。
图7示出了本发明实施例的识别误触摸操作的方法300示意图,该方法300应用于具有触摸屏的电子设备,该触摸屏包括中心区域和边缘区域,该方法可以由电子设备执行,该方法300可以包括:
S310,确定第一触摸操作为误触摸操作;
S320,在该确定第一触摸操作为误触摸操作之后,检测该第一触摸操作对应的多个触摸点形成的第一轨迹;应理解,这里的第一轨迹可以是方法200中的第二轨迹;
S330,若该第一轨迹的方向是从该边缘区域到中心区域再到该边缘区域,则将该第一触摸操作确定为有效触摸操作。
具体而言,电子设备确定第一触摸操作之后,若检测到该第一触摸操作的滑动轨迹是从边缘区域跨到中心区域在到边缘区域时,则将该第一触摸操
作确定为一个正常的触摸操作,即会根据该触摸操作的滑动轨迹来识别来触摸操作,这样,当不管中心区域有没有触摸操作,只要该第一触摸操作跨过边缘区域到中心区域,则会将该触摸操作确定为正常的触摸操作。
例如,该方法300可以应用这样的场景,当用户手指触摸到触摸屏边缘区域的APP图标时,将该触摸操作确定为一个误触摸操作,当该触摸操作时需要将该边缘区域的APP图标放到触摸屏上的垃圾箱中,则从APP图标的位置到垃圾箱的滑动轨迹是从该边缘区域到中心区域再到该边缘区域,则该触摸操作就不会被抑制上报,而是一个有效的触摸操作。
作为一个可选实施例,确定第一触摸操作为误触摸操作,包括:当检测到该第一触摸操作对应的至少一个第一触摸点位于该边缘区域时,检测该中心区域是否存在第二触摸操作,该多个触摸点包括该至少一个第一触摸点;若该中心区域存在该第二触摸操作,将该第一触摸操作确定为误触摸操作。
具体地,当电子设备检测到边缘区域有第一触摸操作时,检测中心区域是否有第二触摸操作,当中心区域有第二触摸操作时,将边缘区域的第一触摸操作确定为误触摸操作,例如,如图4所示的触摸屏,触摸屏边缘线为A线,B线为边缘区域和中心区域的分割线,则边缘区域为A1线到B1线和/或A2线到B2线的区域,中心区域为B1线到B2线的区域,当A1线到B1线或A2线到B2线的区域有第一触摸操作时,检测B1线到B2线的区域是否有第二触摸操作,当B1线到B2线的区域有第二触摸操作时,A1线到B1线或A2线到B2线的区域的第一触摸操作被识别为误触摸操作。
作为一个可选实施例,该边缘区域包括:直接抑制上报区域,该直接抑制上报区域靠近该触摸屏的边缘其中,确定第一触摸操作为误触摸操作,包括:当检测到该第一触摸操作的至少一个第二触摸点位于该直接抑制上报区域时,确定该第一触摸操作为该误触摸操作,该多个触摸点包括该至少一个第二触摸点。
具体地,若第一触摸操作对应的多个触摸点落在直接抑制上报区域,则无论中心区域是否有触摸操作,都将落在直接抑制上报区域的触摸操作当作误触摸操作;若第一触摸操作的轨迹从直接抑制上报区域跨过边缘区域到中心区域再回到直接抑制上报区域,也将该第一触摸操作确定为有效触摸操作,只要第一触摸操作被恢复为有效触摸操作之后,该第一触摸操作再回到直接抑制上报区域则也会被识别为有效触摸操作,通过第一触摸操作的滑动
轨迹来识别是否是真实的触摸操作,进一步可以提高识别的准确性。
作为一个例子,如图6所示,假设A1线到D1线和/或A2线到D2线的区域为直接抑制上报区域,当该第一触摸操作对应的多个触摸点落在A1线到D1线或A2线到D2线的区域,则直接将该第一触摸操作确定为误触摸操作;若该第一触摸对应的触摸点形成的轨迹为a到b到c d到e,则将该第一触摸操作确定为有效触摸操作。
应理解,本发明中边缘区域和中心区域可以根据实际的操作习惯设定,即图5和图6中的不同的线划分都是相对的概念,可以根据不同的需求设定不同的线,本发明实施例对此不作限制。
