Since the analysis of the recorded vibration waveform is complicated, the characteristic index of the vibration signal is relatively first checked - the signal strength. There are also a variety of methods for checking the intensity of the vibration signal. One of the simpler methods may be: the amplitude threshold of the preset vibration signal, and the cumulative calculation of the number of points of the vibration signal waveform exceeding the amplitude threshold. If the preset maximum point value is exceeded, It is judged that the intensity of the vibration signal reaches the preset intensity condition.

Only the vibration signal caused by the tapping touch of the finger on the panel is the signal needed to make a judgment. In addition to requiring the strength of this signal to reach a preset characteristic condition, it can also be compared with a pre-sampled stored reference vibration signal waveform to a frequency-like parameter of the signal (eg, related to the spectral distribution of the signal).
- the description parameter and the time domain parameter are calculated to obtain the characteristic index parameter of the current vibration signal, and the characteristic index parameter of the current vibration signal and the characteristic index parameter of the reference vibration signal are performed. Compare the similarity or correlation coefficient between the two signals, and then check whether the requirements are met against the preset similarity or correlation coefficient threshold conditions. If the requirements are met, for example, the similarity or correlation coefficient exceeds a certain value, it is concluded that a reliable and acceptable vibration signal is detected.
- the touch terminal when the touch terminal is in use, when the system requires the user to input a touch button operation indicating “determination” by using a confirmation type touch gesture, referring to FIG. 2, the touch terminal first detects at least one valid at the T0 time point. Touch the event, and then check the vibration signal recorded from the T1 time point at the T2 time point after the Tb time period. If the reliable qualified vibration signal is detected according to the processing result of the above method, the vibration signal can be used as the prompt presence confirmation type. In the judgment condition of the touch gesture, the touch terminal interprets the effective touch event occurring at the T0 time point as a confirmation type touch gesture, and continues to perform the following confirmation operation. Conversely, if a reliable and qualified vibration signal is not detected during this time period, the touch terminal system will not treat the appearance of the touch event as a confirmation gesture operation, and there will be no following execution.
- the mode of attaching a vibration signal to a touch event proposed by the present invention essentially proposes a special touch input gesture, which can be used not only to indicate a confirming touch gesture, but also to represent some other system definitions. Specific gestures, such as certain actions in the game. If the combined touch event is a multi-touch, then a richer combination of gestures can be produced.

Description
本发明属于触摸屏技术领域，尤其涉及一种触摸终端识别确认型触摸手势的方法及系统。
当前越来越多终端设备上的显示屏支持触摸方式的人机界面，而其中又以电容式触摸屏得到了普遍化的应用。目前在手机、平板电脑或者笔记本等移动终端设备上广泛使用电容式触摸屏，一方面为用户提供了崭新的操作体验，另一方面也还存在一些不足之处，其中一个问题是：由于电容式触摸屏尚且无法检测触摸的力度，因而触摸终端设备也就不能可靠地分辨无意间的触摸与确定的触摸操作。这个问题尤其在进行某些按键操作时更为明显：例如在进行某些关键的确认操作时，手指犹犹豫豫地或者不经意地触摸也会被检测成为确定的触摸，从而导致用户不想要的结果。如果这个触摸操作涉及到交易和支付，出现问题的隐患和后果严重性就会更大。
本发明所要解决的技术问题在于提供一种触摸终端识别确认型触摸手势的方法及系统，旨在使触摸终端能可靠地识别出真正的确认型触摸手势操作。

为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。
对于触摸终端需要输入用户的确认操作的情况，本发明在检测到有效触摸事件时，进一步判断是否检测到有符合预设特征条件的用于提示存在确认型触摸手势的震动信号，当二者兼备时，才认为是触摸终端所需要的真实的确认型触摸手势操作。
图1示出了本发明提供的触摸终端识别确认型触摸手势的方法流程，详述如下。
步骤A，当触摸终端检测到触摸屏上存在有效触摸事件时，进一步判断在所述有效触摸事件发生前后的预设时间段内，是否检测到有符合预设特征条件的用于提示存在确认型触摸手势的震动信号。
步骤B，若步骤A判断结果为是，则识别所述有效触摸事件为真实的确认型触摸手势操作。
如图2所示，如果T0是有效触摸事件发生的时间，那么在T0之前的Ta或之后的Tb时间段内若检测到了符合预设特征条件的用于提示存在确认型触摸手势的震动信号，即可判断检测到真实的确认型触摸手势操作。根据不同的触摸终端的系统设计，检测触摸事件和震动信号会存在一定的时间差，也就是说震动信号可能出现在触摸事件前面也可能出现在触摸事件后面。一般而言，Ta和Tb的取值在50ms以内。此外，需要指出的是，这里所说的有效触摸事件可以是多个触摸点的触摸事件，如果这些多点触摸事件是在一个特定时间范围(例如50ms)内同时发生的。
上述用于提示存在确认型触摸手势的震动信号可以灵活定义为各种形式的特定触摸操作所产生，如单击、双击等敲击触摸终端面板部分的操作，可以是敲击触摸屏区域，也可是面板上除触摸屏以外的其他区域等等。按照上述方法，触摸事件应该是发生在触摸面板上，但是允许敲击的位置与触摸的位置不是同一位置。不过，大部分情况下都会采取用指头直接敲击触摸面板的操作方式。下文仅以敲击触摸面板类型的操作为例进行描述。
参照图3，步骤A中判断是否检测到有符合预设特征条件的用于提示存在确认型触摸手势的震动信号的步骤具体为：
步骤A1，判断在所述有效触摸事件发生前后的预设时间段内是否有符合预设强度条件的震动信号。
如上文所述，以敲击的方式让指头触摸面板，除了让触摸面板检测到触摸事件之外，触摸终端还可以检测到终端机体的震动信号。图5即为一个面板上敲击触摸手势引起紧贴面板安装的麦克风所记录的波形。由于对于所记录的震动波形的分析比较复杂，所以首先检验震动信号比较简单的特征指标——信号强度。检验震动信号强度的方法也有多种，其中比较简单的一种可以是：预设震动信号的幅度阈值，累计计算震动信号波形超出幅度阈值的采用点数，如果超过预设的最大点数值，则可以判断为此震动信号的强度达到了预设的强度条件。注意，考虑波形的幅度时是用它的采样值的绝对值。
步骤A2，若步骤A1判断结果为是，则进一步判断所述震动信号的特征指标参数与参考震动信号的特征指标参数对比是否满足预设的相似度或相关系数阈值条件。
步骤A3，若步骤A2判断结果为是，则确定检测到的有符合预设特征条件的用于提示存在确认型触摸手势的震动信号。
对于判断为达到预设强度条件的震动信号，为了提高判断的可靠性，需要进一步检验其幅度以外的其他特征指标参数。只有真正是由于手指对面板的敲击式触摸引起的震动信号，才是做出判断所需要的信号。除了要求这个信号的强度达到预设特征条件以外，还可以通过与一个预先采样保存的参考震动信号波形进行对比，以一种类似语音识别的算法，对信号的频域参数（例如涉及信号频谱分布的描述参数）和时域参数（例如涉及信号幅度包络形状的描述参数）进行计算得出当前震动信号的特征指标参数，并且将当前震动信号的特征指标参数与参考震动信号的特征指标参数进行对比得出两个信号之间的相似度或相关系数，然后对照预设的相似度或相关系数阈值条件检验是否达到要求。如果达到要求，例如相似度或相关系数超过某个值，则得出结论：检测到了可靠合格的震动信号。
根据以上实施例，触摸终端在使用过程中，当系统需要用户采用确认型的触摸手势输入表示“确定”意思的触摸按键操作时，参见图2，触摸终端先在T0时间点检测到至少一个有效触摸事件，然后经过Tb时间段后在T2时间点检查从T1时间点开始记录的震动信号，如果按照上述方法的处理结果检测到了可靠合格的震动信号，那么这个震动信号就可以作为提示存在确认型触摸手势的判断条件，触摸终端即把T0时间点发生的有效触摸事件解释为确认型触摸手势，继续执行下面的确认操作。反过来讲，如果没有在这个时段检测到可靠合格的震动信号，那么触摸终端系统也就不会把出现的触摸事件当成确认手势操作，也就不会有下面的继续执行。
显然，本发明提出的这个在触摸事件上附加震动信号的模式实质上是提出了一种特殊的触摸输入手势，不仅仅可以用于表示确认型触摸手势，也可以用来表示一些其他的系统定义的特定手势，例如游戏中的某种动作。如果所结合的触摸事件是一个多点触摸，那么就可以产生更为丰富的手势组合了。
本领域普通技术人员可以理解实现上述各实施例提供的方法中的全部或部分步骤可以通过程序来指令相关的硬件来完成，所述的程序可以存储于一计算机可读取存储介质中，该存储介质可以为ROM/RAM、磁盘、光盘等。
图6是本发明实施例提供的触摸终端识别确认型触摸手势的系统结构原理，为了便于描述，仅示出了与本实施例相关的部分。本系统可内置于各种触摸终端中。
参照图6，本触摸终端识别确认型触摸手势的系统包括触摸检测单元61、震动信号检测单元62和确认型触摸手势识别单元63，触摸检测单元61用于检测触摸终端的触摸屏上是否存在有效触摸事件，具体可采用矩阵形式的触摸传感器和触摸检测控制模块实现，如图6所示，触摸传感器和触摸检测控制模块相连接。震动信号检测单元62用于检测是否有符合预设特征条件的用于提示存在确认型触摸手势的震动信号，并记录，具体检测原理如上文所述。确认型触摸手势识别单元63在触摸检测单元61检测到触摸屏上存在有效触摸事件时，进一步判断震动信号检测单元62检测到的信号是否符合用于提示存在确认型触摸手势的震动信号的预设特征条件，若判断结果为是，则将所述有效触摸事件识别为真实的确认型触摸手势操作，并输出识别结果。
如上文所述，所述用于提示存在确认型触摸手势的触摸操作为敲击类型的触摸操作；敲击触摸引起安装有震动传感器的触摸终端检测到机体震动。震动信号检测单元62包括震动传感器和震动检测控制模块，震动传感器可以是麦克风器件或MEMS（Micro-Electro-Mechanical
Systems，微机电系统）器件，安装于触摸终端内部，具体位置不限，只有能检测到触摸终端受到的震动即可；震动检测控制模块与所述震动传感器连接，用于在所述有效触摸事件发生前后的预设时间段内判断震动传感器是否检测到有符合预设特征条件的用于提示存在确认型触摸手势的震动信号。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
