Description

一种检测触摸方式的方法及装置 技术领域
本发明涉及终端设备技术领域，尤其涉及一种检测触摸方式的方法及装置。
背景技术
随着触摸屏式智能终端技术的迅速发展，触摸屏上可用的触摸手势变得越来越丰富，比如手指滑动触摸、手指点击触摸、单指触摸、双指触摸等，不同的触摸手势指示了不同的触摸指令。为了进一步丰富触摸手势，满足触摸指令越来越多的需求，出现了对手指触摸和指关节触摸两种触摸方式的区分。比如，当用户用手指点击一幅图片时，图片会正常打开；而用指关节点击时，则会弹出该图片的菜单选项功能，就如点击电脑鼠标右键那样。
针对手指触摸和指关节触摸两种触摸方式，主要通过触摸屏的触摸信号，如电容信号，以及加速度传感器在Z轴方向的加速度值来区分，比如，当检测到的电容信号所指示的最大电容值较大、且加速度传感器在Z轴方向的最大加速度值较小时，将触摸方式识别为手指触摸，相反，当检测到的电容信号所指示的最大电容值较小、且加速度传感器在Z轴方向的最大加速度值较大时，将触摸方式识别为指关节触摸。
但是，触摸屏的触摸信号和加速度信号经常会受到终端设备内和设备外、除真实用户的触摸之外的环境因素的影响，从而导致检测出的触摸方式出错，进而导致终端设备执行了错误的执行指令。

S101：当检测到来自触摸屏的触摸信号时，确定加速度传感器输出的Z轴方向的加速度信号，以及影响对作用于所述触摸屏上的触摸方式的检测的补偿参数信息；其中，所述触摸信号为触摸屏基于用户的触摸动作转换的电信号；所述触摸信号可以包括触点坐标、触摸屏网格电容值、触摸动作中的一种或多种信号。
这里，基于感应原理的不同，触摸屏的类型有多种，比如电容式触摸屏、电阻式触摸屏、红外线式触摸屏、表面声波式触摸屏等，为了便于说明，本发明实施例以电容式触摸屏为例。
在本发明实施例中，影响对作用于所述触摸屏上的触摸方式的检测的补偿参数信息可以包括：用于调整所述Z轴方向的加速度信号的第一参数信息和/或用于确定所述终端设备的工作状态的第二参数信息；
其中，所述第一参数信息可以包括马达振动状态补偿信息、音视频播放状态补偿信息、和角速度传感器的信号补偿信息中的一种或多种；

上述马达振动状态补偿信息用于指示马达振动产生的Z轴方向的加速度信号；音视频播放状态补偿信息用于指示音视频播放产生的Z轴方向的加速度信号；角速度传感器(比如陀螺仪)的信号补偿信息用于指示角速度传感 器检测到的Z轴方向的角速度信号。
下面在关于S102的描述中将会进一步说明上述补偿参数信息的作用。
S102：基于检测到的触摸信号、所述Z轴方向的加速度信号以及补偿参数信息，确定作用于所述触摸屏上的触摸方式。
本发明实施例中的触摸方式可以包括手指触摸、指关节触摸、和误触摸。
基于上述第一参数信息和/或第二参数信息，上述S102的具体执行过程为：
当所述补偿参数信息包括所述第一参数信息，不包括所述第二参数信息时，基于所述第一参数信息对所述Z轴方向的加速度信号进行调整；基于检测到的触摸信号和调整后的Z轴方向的加速度信号，确定作用于所述触摸屏上的触摸方式；
当所述补偿参数信息包括所述第二参数信息，不包括所述第一参数信息时，基于所述第二参数信息确定所述终端设备的工作状态信息，当确定所述工作状态信息为非主动触摸状态时，不对作用于所述触摸屏上的触摸方式进行识别；当确定所述工作状态信息为主动触摸状态时，基于检测到的触摸信号和所述Z轴方向的加速度信号，确定作用于所述触摸屏上的触摸方式；
当所述补偿参数信息包括所述第一参数信息和所述第二参数信息时，基于所述第二参数信息确定所述终端设备的工作状态信息；当确定所述工作状态信息为非主动触摸状态时，不对作用于所述触摸屏上的触摸方式进行识别；当确定所述工作状态信息为主动触摸状态时，基于所述第一参数信息对所述Z轴方向的加速度信号进行调整，并基于检测到的触摸信号和调整后的Z轴方向的加速度信号，确定作用于所述触摸屏上的触摸方式。
具体地，在上述各种具体的补偿参数信息中：
对于马达振动状态补偿信息：当触摸事件同时有马达振动事件，此时用于检测触摸方式的加速度信号为触摸事件在Z轴方向的加速度信号与马达振动产生的Z轴方向的加速度信号的叠加信号；因此马达振动产生的Z轴方向的加速度信号则构成了检测触摸事件的干扰信号，基于带有干扰信号的加速度信号检测触摸方式会影响检测结果的正确性，因此需要在所述带有干扰信 号的加速度信号中过滤掉干扰成分，这里的干扰成分即为：马达振动产生的Z轴方向的加速度信号，基于过滤掉马达振动产生的Z轴方向的加速度信号后的加速度信号检测触摸方式以保证触摸方式检测的正确性。如图2(a)所示，为手指触摸时的重力传感器的信号波形图，图2(b)所示，为指关节触摸时的重力传感器的信号波形图，图2(c)所示，为马达振动时产生的周期性的振动信号波形示意图，一旦该振动信号与图2(a)所示手指触摸时的信号叠加，形成如图2(d)所示信号波形，就可能导致叠加后的信号可以表征指关节触摸方式，从而导致检测的触摸方式出错。因此，针对这种情况，可以在Z轴方向的加速度信号中过滤掉马达振动产生的干扰信号(马达振动产生的Z轴方向的加速度信号)，如图2(e)所示，再基于调整后的Z轴方向的加速度信号，以及所述触摸信号，确定在所述触摸屏上产生的触摸方式。
对于音视频播放状态补偿信息：当触摸事件同时有音视频播放事件，此时用于检测触摸方式的加速度信号为触摸事件在Z轴方向的加速度信号与音视频播放产生的Z轴方向的加速度信号的叠加信号；音视频播放产生的Z轴方向的加速度信号则构成了检测触摸事件的干扰信号，需要在所述带有干扰信号的Z轴方向的加速度信号中过滤掉干扰成分，这里的干扰成分即为：音视频播放产生的Z轴方向的加速度信号，基于过滤掉音视频播放产生的Z轴方向的加速度信号后的加速度信号检测触摸方式以保证触摸方式检测的正确性。由于音视频的频率以及响度的不同，音视频播放产生的Z轴方向的加速度信号也不同，所述音视频播放产生的Z轴方向的加速度信号可以是预先设置的，也可以随着音视频播放动态调节。
对于角速度传感器的信号补偿信息：角速度传感器可以感应终端设备的移动方向，例如左转右转。当终端做圆形轨迹运动(比如用户乘坐旋转木马)时，角速度传感器会产生角速度信号，也即离心力信号，当角速度信号在Z轴方向有分量时，用于检测触摸方式的加速度信号为触摸事件在Z轴方向的加速度信号与Z轴方向的角速度信号的叠加信号；Z轴方向的角速度信号则构成了检测触摸事件的干扰信号，需要在所述带有干扰信号的加速度信号中 过滤掉干扰成分，这里的干扰成分即为：Z轴方向的角速度信号，基于过滤掉Z轴方向的角速度信号后的加速度信号检测触摸方式以保证触摸方式检测的正确性。
当接近光传感器被物体遮挡住或者处于黑暗的环境时，会输出一个“遮挡”信号，利用接近光传感器可以对终端设备的工作状态进行识别，比如，当接近光传感器被遮挡时，用户很有可能在打电话，或者将触摸屏靠近了头部或者脸部，此时如果用户的耳朵或者头骨碰到触摸屏，就会发生触摸事件，而显然，这时候的触摸都是误触摸，因此，通过接近光传感器输出的“遮挡”信号，可以确定所述终端设备处于非主动触摸状态，即产生的触摸事件不是用户主动触摸，可以忽略此次触摸事件，不进行触摸方式的识别。
同理，当环境光传感器周围没有光的时候，环境光传感器会输出一个“暗”的信号，利用环境光传感器可以对终端设备的工作状态进行识别，比如，当环境光传感器被遮挡时，终端设备可能是被放在包里，此时若用户的钥匙或者硬币触碰触摸屏，就会发生触摸事件，显然，这时候产生的触摸事件不是用户主动触摸，因此，通过环境光传感器输出的“暗”信号，可以确定终端设备处于非主动触摸状态，可以忽略此次触摸事件，不进行触摸方式的识别。
基于上述描述内容，在S102的具体执行过程中，基于所述第一参数信息对所述Z轴方向的加速度信号进行调整，包括：
当所述第一参数信息包括所述马达振动状态补偿信息时，在所述Z轴方向的加速度信号中过滤掉因马达振动产生的Z轴方向的加速度信号；
当所述第一参数信息包括所述音视频播放状态补偿信息时，在所述Z轴方向的加速度信号中过滤掉因音视频播放产生的Z轴方向的加速度信号；
当所述第一参数信息包括所述角速度传感器的信号补偿信息时，在所述Z轴方向的加速度信号中过滤掉Z轴方向的角速度信号。
以下实施例为体现上述思想的一个较具体的实施例。
如图3所示，为本发明另一实施例提供的检测触摸方式的方法流程图，包括以下步骤：
S301：当检测到来自触摸屏的触摸信号后，确定加速度传感器输出的Z轴方向的加速度信号，以及影响对作用于所述触摸屏上的触摸方式的检测的第一参数信息和第二参数信息；所述第一参数信息用于调整所述Z轴方向的加速度信号，包括马达振动状态补偿信息、音视频播放状态补偿信息、和角速度传感器的信号补偿信息中的一种或多种；所述第二参数信息用于确定所述终端设备的工作状态，所述第二参数信息包括接近光传感器的信号状态信息和/或环境光传感器的信号状态信息。
S302：在基于所述第二参数信息确定所述终端设备处于非主动触摸状态时，不对作用于所述触摸屏上的触摸方式进行识别，在基于所述第二参数信息确定所述终端设备处于主动触摸状态时，基于所述第一参数信息对所述Z轴方向的加速度信号进行调整。
该步骤中，基于接近光传感器和/或环境光传感器输出的指示被遮挡的信号，可以获知在产生触摸信号的时间范围内是否终端设备处于非主动触摸状态(终端设备当前不会出现用户主动触摸所述触摸屏的情况)，若终端设备处于非主动触摸状态，说明此次触摸事件为误触摸，不对触摸方式进行识别，若终端设备处于主动触摸工作状态，则基于第一参数信息对Z轴方向的加速度信号进行调整。具体地，在Z轴方向的加速度信号中，过滤掉干扰信号，比如马达振动时产生的Z轴方向的加速度信号、音视频播放产生的Z轴方向的加速度信号、终端设备内设置的角速度传感器输出的Z轴方向的角速度信号。
S303：基于检测到的触摸信号和调整后的Z轴方向的加速度信号，确定作用于所述触摸屏上的触摸方式。
该步骤中，如果确定终端设备处于主动触摸工作状态，基于来自触摸屏的触摸信号及调整后的Z轴方向的加速度信号，确定作用于所述触摸屏上的触摸方式是手指触摸，还是指关节触摸。比如，当触摸屏为电容式触摸屏时，可以基于获取的触摸信号确定电容值分布信息(各个网格内分布的电容值)，并基于调整后的Z轴方向的加速度信号确定Z轴方向的加速度值，基于确定 的电容值分布信息和加速度值，确定触摸方式。比如，当确定的电容值分布信息中指示最大电容值在第一设定范围内(比如大于0.42pF、小于或等于0.46pF)，并且分布有非零电容值的网格个数大于或等于7，在设定时间段内，加速度最大值小于设定的阈值(比如，在5ms内，加速度最大值为2g，小于设定的阈值3g，g为重力加速度)时，确定该触摸方式为手指触摸；当确定的电容值分布信息中指示最大电容值在第二设定范围内(比如小于或等于0.42pF)，分布有非零电容值的网格个数小于7，在设定时间段内，加速度最大值大于设定的阈值(比如为3g)时，确定该触摸方式为指关节触摸。
