- the touch operation includes a long press operation or a slide operation on the touch screen.
- a capacitive touch screen determines a touch point by sensing a change in capacitance generated by a human touch. It has two sets of signal lines: a driving line and a sensing line, the driving line transmits a signal, and the sensing line detects a change in the capacitance value.
- the finger touches the metal layer, due to the presence of the human body electric field, the finger and the touch screen
- the surface forms a coupling capacitor.
- the capacitor is a direct conductor, so the finger draws a small current from the contact point.
- the coupling between the two electrodes near the touch point is affected, thereby changing the capacitance between the two electrodes.
- the electrodes in the direction of the driving line sequentially emit excitation signals, and all the electrodes in the direction of the sensing line receive signals at the same time, so that the capacitance values of all the intersections of the lateral and longitudinal electrodes can be obtained, that is, the two-dimensional plane of the entire touch screen.

- the Android system provides the onTouchEvent() method to capture user touch events.
- OnTouchEvent() There are three types of events that are often used: ACTION_DOWN, ACTION_MOVE, and ACTION_UP. These three events identify the most basic user touch screen operations, such as touch, long press, and swipe.
- the MotionEvent class in Android provides functions (getX(), getY()) that record the current coordinates, a function that presses the time (getDowntime()), and a function that ends the current event (getEventTime()).
- MotionEvent also provides the current type of operation, such as pressing (ACTION_DOWN), moving (ACTION_MOVE), or popping (ACTION_UP).
- the system acquires a touch operation acting on the touch screen through getAction(). Then, the coordinates of each contact are obtained by acquiring a function (getX(), getY()) that touches the current coordinates. A touch operation acting on the preset anti-missing area is determined based on the coordinates. Wherein, if at least one contact in the touch operation is located in the preset anti-missing area, it is determined that the touch operation acts on the preset anti-missing area.
- the press time can be obtained by the getDowntime() function, and the touch event end time is obtained by getEventTime(), and the difference between the two is the duration of the touch operation.
- the pressure value of the user's finger pressing the touch screen can be obtained by getPressure().

- the set time threshold is used to distinguish whether the touch operation is a false press or a normal long press operation.
- There are many ways to determine the set time threshold For example, you can investigate the duration of long-press operation of different types or shapes of mobile terminals by user groups of different ages, and determine the duration of long-press operation of most users.
- a time greater than the duration is set arbitrarily as the set time threshold, and is configured in the mobile terminal before the mobile terminal leaves the factory.
- the user can enter the long press operation input function before starting to use the mobile terminal.
- the mobile terminal collects relevant data of the user long press on the touch screen, and analyzes the duration of the long press operation of the user according to the collected data.
- the duration is added to a fixed value as a set time threshold.
- the duration is compared to a set time threshold. If the duration exceeds the set time threshold, a trend graph of the change in touch pressure value over time for the duration of time is determined. According to the trend graph, the variation law of the touch pressure during the duration can be determined. If the duration is less than the set time threshold, it may be determined that the touch operation corresponding to the duration is a long press operation.
- Step 140 When the change rule conforms to a preset rule, the anti-missing function of the edge of the touch screen is turned on.
- the preset rule includes: in a time interval corresponding to the duration, the touch pressure value of the touch operation fluctuates on a basis of a set value, and the error with the reference is within a set value range .
- the change rule of the touch operation is matched with the preset rule.
- the mobile terminal controls the anti-missing function of the edge of the touch screen to be turned on.

移动终端用户通过触摸屏可轻松快捷地实现对移动终端的各种操作。基于让移动终端的屏幕上能够显示更多的内容以及提升用户的观感体验等因素,触摸屏的尺寸越来越大,在这种趋势下,为了兼顾移动终端的便携性以及美观度,屏占比成为了一个衡量移动终端性能的新指标。为了追求较高的屏占比,降低屏幕边框对视觉效果的影响,窄边框或者无边框设计已成为各移动终端厂商争先采用的用于优化移动终端的手段,而窄边框及无边框移动终端也越来越受到消费者的青睐。

下面结合附图和实施例对本发明作进一步的详细说明。可以理解的是,此处所描述的具体实施例仅仅用于解释本发明,而非对本发明的限定。另外还需要说明的是,为了便于描述,附图中仅示出了与本发明相关的部分而非全部结构。
在更加详细地讨论示例性实施例之前应当提到的是,一些示例性实施例被描述成作为流程图描绘的处理或方法。虽然流程图将各步骤描述成顺序的处理,但是其中的许多步骤可以被并行地、并发地或者同时实施。此外,各步骤的顺序可以被重新安排。当其操作完成时所述处理可以被终止,但是还可以具有未包括在附图中的附加步骤。所述处理可以对应于方法、函数、规程、子例程、子程序等等。
图1为本发明实施例提供的一种触摸屏控制方法的流程图,该方法可以由触摸屏控制装置来执行,其中,该装置可由软件和/或硬件实现,一般可集成
在终端中,特别是移动终端中。如图1所示,该方法包括如下步骤:
步骤110、在检测到终端的屏幕状态是第一状态时,关闭触摸屏边缘的防误触功能。
本发明实施例中,终端可以是智能手机、平板电脑、掌上游戏机及个人数字助手等集成了触摸屏的电子设备,优选为采用窄边框、无边框或者曲面屏设计的移动终端。
屏幕状态包括熄屏状态、亮屏状态、横屏状态、竖屏状态或屏幕倾斜状态等。第一状态可以是横屏状态。第一状态还可以是屏幕与水平面成设定角度倾斜的状态。可以理解的是,获取终端的屏幕方向的方式有多种,本实施例不作具体限定。例如,可以通过调用标准接口获取该终端的屏幕状态信息。又如,可以根据重力传感器的检测数据确定当前终端的屏幕是竖屏还是横屏。再如,还可以通过指纹传感器的检测数据确定当前终端的屏幕方向信息。由于移动终端的屏幕为横屏时,用户在握持移动终端的过程中,拇指很容易触摸到指纹传感器。从而,触发指纹传感器检测拇指与其接触区域的指纹。进而,发生指纹传感器检测到非正常指纹的情况。若指纹传感器检测到非正常指纹的频率超过设定频率阈值,则确定移动终端的显示屏是横屏。
对于智能手机、掌上游戏机、个人数字助手及平板电脑等,采用窄边框、无边框或者曲面屏设计的移动终端,其采用的触摸屏包括电阻式触摸屏、电容式触摸屏和压电式触摸屏等。当用户触碰触摸屏时,触摸屏会检测到触摸信息,进而识别出用户的触摸操作。为了避免触摸屏边缘的误触操作影响正常操作,移动终端上通常集成有触摸屏边缘防误触功能。边缘防误触功能是在触摸屏边缘预设一设定形状和/或大小的区域,将该区域标记为防误触区域。图2a是移动终端触摸屏的一种防误触区域示意图。如图2a所示,移动终端的触摸屏201的左右两侧分别包含了第一预设防误触区域202和第二预设防误触区域203。如果用户按住触摸屏的该防误触区域的时候,再点击触摸屏的其它区域,则释放防误触区域的手指信息,响应触摸屏其它区域的点击操作。其中,防误触区域的确定方式可以有很多种,例如,可调研用户群体对不同型号或外形的移动终端的握持方式及姿势等情况,将多数用户容易误触的屏幕区域设置为防误触区域,并在移动终端出厂前完成设置。又如,用户在开始使用移动终端前,也可进入握持方式录入功能,由移动终端采集用户握持移动终端的相关数据,根
据采集的数据分析出用户容易误触的区域,将该区域设定为防误触区域。
本实施例对防误触区域的形状、面积和数量不做具体限定。图2a中预设防误触区域形状为长方形,长度与触摸屏显示区域的长度相同。防误触区域的形状还可以是口字形,且大拇指对应的一侧的宽度大于相对的另一侧的宽度,有效避免手掌接触触摸屏导致误触操作。防误触区域的形状还可以是半椭圆形或其他不规则形状,尺寸大小也可根据实际情况进行设置。此外,防误触区域的具体位置也可进行调整,例如,可位于触摸屏的左右边缘,还可位于触摸屏边缘的左下方和/或右下方。
触摸屏边缘的防误触功能可以由系统根据移动终端的使用情况自动开启或关闭。移动终端在检测到当前终端使用情况满足关闭防误触功能的要求时,控制触摸屏边缘的防误触功能关闭。示例性的,通过设定标准接口获取终端的当前屏幕状态;在当前屏幕状态是横屏状态时,关闭触摸屏边缘的防误触功能。优选的,在移动终端系统为安卓系统时,可以通过getConfiguration()获取当前移动终端屏幕处于横屏状态或竖屏状态。图2b是本发明实施例提供的一种移动终端的触摸屏的示意图。如图2b所示,系统检测到终端的屏幕状态是横屏状态,满足预设的关闭防误触功能的要求,控制触摸屏边缘的防误触功能关闭。移动终端在检测到当前终端的使用情况满足开启防误触功能的要求时,控制触摸屏边缘的防误触功能开启。
可以理解的是,终端还可以根据用户输入的操作指示开启或关闭防误触功能。示例性的,可以在移动终端中配置用于开启或关闭防误触功能的应用软件,通过点击该应用软件对应的图标,实现开启或关闭防误触功能。优选的,在该应用软件安装完成后,提示用户是否将该应用软件图标添加至下拉菜单。若移动终端接收到用户输入的添加指示,则在移动终端的下拉菜单中显示该应用软件,方便用户控制防误触功能的开启或关闭。
步骤120、在检测到作用于预设防误触区域的触摸操作时,获取所述触摸操作的触摸压力和持续时间。
其中,所述触摸操作包括触摸屏上的长按操作或滑动操作。
以电容式触摸屏为例,其通过感应人体触摸所产生的电容变化而判断触摸点。其具有两组信号线:驱动线与感应线,驱动线发射信号,感应线侦测电容值的变化。当手指触摸在金属层上时,由于人体电场的存在,手指和触摸屏表
面形成一个耦合电容,对于高频电流来说,电容是直接导体,于是手指从接触点吸走一个很小的电流。影响了触摸点附近两个电极之间的耦合,从而改变了这两个电极之间的电容量。检测互电容大小时,驱动线方向的电极依次发出激励信号,感应线方向的所有电极同时接收信号,这样可以得到所有横向和纵向电极交汇点的电容值的变化,即整个触摸屏的二维平面的电容大小,根据触摸屏二维电容变化量数据,可以计算出每一个触摸点的坐标,因此屏上即使有多个触摸点,也能计算出每个触摸点的真实坐标。从而,可以确定包括触摸点的x坐标、y坐标、接触面的尺寸(包括长和宽等)以及触摸的手指数量等触摸信息,在识别到触摸信息后,通过input系统向上层上报坐标信息,便可利用触摸信息检测到屏幕的某处发生的触摸操作(可以包括触摸位置和触摸类型)。
为了实时的感应用户对屏幕的手指操作,安卓系统提供了onTouchEvent()方法来捕获用户触摸事件,其经常使用的有三类事件:按下(ACTION_DOWN)、滑动(ACTION_MOVE)和弹起(ACTION_UP)。这三个事件标识出了最基本的用户触摸屏幕的操作,例如点击、长按及滑动等触摸操作。安卓系统中MotionEvent类提供了记录当前坐标的函数(getX(),getY())、按下时间的函数(getDowntime())和当前事件结束时间的函数(getEventTime())。MotionEvent同时也提供了当前的操作类型,如按下(ACTION_DOWN)、移动(ACTION_MOVE)或弹起(ACTION_UP)。
示例性的,系统通过getAction()获取作用于触摸屏的触摸操作。然后,通过获取触摸操作当前坐标的函数(getX(),getY()),获取各个触点的坐标。根据该坐标确定作用于预设防误触区域的触摸操作。其中,若触摸操作中的至少一个触点位于预设防误触区域,则确定该触摸操作作用于该预设防误触区域。
对于作用于预设防误触区域的触摸操作,可以通过getDowntime()函数获取按下时间,通过getEventTime()获取触摸事件结束时间,两者的差值为该触摸操作的持续时间。可以通过getPressure()获取用户手指按压触摸屏的压力值。
可以理解的是,本实施例提供的在检测到作用于预设防误触区域的触摸操作时,获取所述触摸操作的触摸压力和持续时间的方法仅是一个示例,还可以采用其它方法获取触摸操作的触摸压力和持续时间。
步骤130、在所述持续时间超过设定时间阈值时,确定所述触摸压力在所
述持续时间内的变化规律。
设定时间阈值用于区别触摸操作是误按压还是正常的长按操作。确定设定时间阈值的方式有很多种,例如,可以调研不同年龄的用户群体对不同型号或外形的移动终端的长按操作的持续时长,确定多数用户的长按操作的持续时长。任意设定一大于该持续时长的时间作为设定时间阈值,并在移动终端出厂前,配置在移动终端中。又如,用户在开始使用移动终端前,可先进入长按操作录入功能。由移动终端采集用户长按触摸屏的相关数据,根据采集的数据分析出用户长按操作的持续时长。将该持续时长加一固定值作为设定时间阈值。
示例性的,将该持续时间与设定时间阈值进行比较。若该持续时间超过设定时间阈值,则确定该持续时间长度内的触摸压力值随时间变化的趋势图。根据该趋势图可以确定该触摸压力在该持续时间内的变化规律。若该持续时间小于设定时间阈值,可以确定该持续时间对应的触摸操作为长按操作。
步骤140、在所述变化规律符合预设规律时,开启触摸屏边缘的防误触功能。
其中,所述预设规律包括:在所述持续时间对应的时间区间内,所述触摸操作的触摸压力值以设定值为基准进行波动,且与所述基准的误差在设定数值范围内。
对于作用于预设防误触区域且持续时间超过设定时间阈值的触摸操作,将该触摸操作的变化规律与预设规律进行匹配。在该变化规律符合预设规律时,移动终端控制触摸屏边缘的防误触功能开启。
本实施例的技术方案,通过在检测到终端的屏幕状态是第一状态时,关闭触摸屏边缘的防误触功能;在检测到作用于预设防误触区域的触摸操作时,获取所述触摸操作的触摸压力和持续时间;在所述持续时间超过设定时间阈值时,确定所述触摸压力在所述持续时间内的变化规律;在所述变化规律符合预设规律时,开启触摸屏边缘的防误触功能,实现在用户握持移动终端的手掌长时间压住触摸屏时,屏蔽该压住触摸屏的触摸操作,使移动终端可以正常响应用户的其它触摸操作。本发明实施例解决用户握持移动终端时,手掌长时间压住触摸屏可能影响用户正常使用移动终端的问题,达到了防止触摸屏边缘发生误触操作,提高移动终端的屏幕触摸事件处理的准确度的效果。
在上述技术方案的基础上,在开启触摸屏边缘的防误触功能之后,还包括:
对于符合预设规律的触摸操作执行屏蔽操作,对于不符合预设规律的触摸操作执行响应操作。这样设置的好处在于,若用户不小心按住移动终端的防误触区域,不影响对其它区域的正常操作。例如,用户在观看视频时,握持移动终端的手掌长时间压住触摸屏,不会影响用户另一只手在触摸屏边缘滑动调节音量、屏幕亮度或播放进度。
图3a是本发明实施例提供的另一种触摸屏控制方法的流程图。如图3所示,本方法包括如下步骤:
步骤310、在终端的屏幕状态是横屏状态时,关闭触摸屏边缘的防误触功能。
触摸屏包括面板、接触性传感器、柔性电路板及触摸IC(触摸芯片)。其中,面板为触摸屏的表层,用户的触摸操作作用于该面板上。根据触摸屏的结构与触摸IC设计要求制作接触性传感器。接触性传感器通过柔性电路板与触摸IC电连接。通过在触摸IC内烧录驱动程序,即可控制触摸屏以设定的检测灵敏度检测触摸操作,并按照设定上报频率将触摸操作对应的触摸信息上报至移动终端处理器。具体的,触控IC包括防误触功能开启/关闭标志位、灵敏度标志位及上报频率标志位等。通过调整灵敏度标志位的取值,调整触摸屏检测触摸操作的灵敏度。通过调整上报频率标志位,调整触摸感应的速度。通过调整防误触功能开启/关闭标志位的取值,控制触摸屏边缘的防误触功能开启或关闭。
示例性的,终端在检测到当前屏幕的状态信息为横屏状态时,修改该触摸IC中防误触功能开启/关闭标志位的取值为代表关闭防误触功能的数值,以关闭触摸屏边缘的防误触功能。
步骤320、在检测到作用于预设防误触区域的触摸操作时,获取所述触摸操作的触摸压力和持续时间。
如图2b所示,用户双手握持移动终端时,一只手的手掌压住触摸屏201的预设防误触区域。此时,移动终端在预设防误触区域检测到区域204处发生触摸操作。系统执行设定函数,获得该触摸操作的触摸压力和持续时间。
步骤330、判断持续时间是否超过设定时间阈值,若是,则执行步骤340,若否,则执行步骤380。
步骤340、确定所述触摸压力在所述持续时间内的变化规律。
步骤350、判断变化规律是否符合预设规律,若是,则执行步骤360,若否,则执行步骤380。
将该作用于预设防误触区域,且持续时间超过设定时间阈值的触摸操作的触摸压力的变化规律与预设规律进行匹配。若匹配成功,则执行步骤360。若匹配失败,则执行步骤380。
步骤360、开启触摸屏边缘的防误触功能。
移动终端在变化规律与预设规律匹配成功时,修改该触摸IC中防误触功能开启/关闭标志位的取值为代表开启防误触功能的数值,以开启触摸屏边缘的防误触功能。
步骤370、对于符合预设规律的触摸操作执行屏蔽操作,对于不符合预设规律的触摸操作执行响应操作。
图3b是图3a提供的另一种触摸屏控制方法中具体步骤的流程图如图3b所示,步骤370具体包括:
步骤371、在检测到作用于预设防误触区域的触摸操作时,获取所述触摸操作的触摸压力和持续时间。
步骤372、判断持续时间是否超过设定时间阈值,若是,则执行步骤373,若否,则执行步骤376。
步骤373、确定所述触摸压力在所述持续时间内的变化规律。
步骤374、判断变化规律是否符合预设规律,若是,则执行步骤375,若否,则执行步骤376。
步骤375、对该触摸操作执行屏蔽操作,返回执行步骤371。
步骤376、对该触摸操作执行响应操作。
在开启触摸屏边缘的防误触功能后,若检测到作用于预设防误触区域的触摸操作,则判断该触摸操作的持续时间是否超过设定时间阈值。在该持续时间超过设定时间阈值,确定该触摸操作的触摸压力在该持续时间内的变化趋势图。根据该变化趋势图可以确定该触摸操作的触摸压力的变化规律,从而,确定作用于触摸屏的触摸操作是否符合预设规律。对于符合预设规律的触摸操作执行屏蔽操作,对于不符合预设规律的触摸操作执行响应操作。
步骤380、保持触摸屏边缘的防误触功能处于关闭状态。
若所述持续时间未超过设定时间阈值,或所述变化规律不符合预设规律,
则保持触摸屏边缘的防误触功能处于关闭状态。
本实施例的技术方案,通过响应不符合预设规律的触摸操作,屏蔽符合预设规律的触摸操作,实现屏蔽用户长时间且无意识的误触操作,避免该类误触操作对用户正常触摸屏幕造成影响。同时,移动终端不执行该类误触操作,降低了移动终端的耗电量。本发明实施例解决用户握持移动终端时,手掌长时间压住触摸屏可能影响用户正常使用移动终端的问题,达到了防止触摸屏边缘发生误触操作,提高移动终端的屏幕触摸事件处理的准确度的效果。
