【具体实施方式】
下面结合附图和实施方式对本发明进行详细说明。
为保证本发明能正常实施，本发明终端的触摸屏为能采集到触碰动作对应触碰区域的形状和/或大小的触摸屏。一般用户使用手指、触屏笔或手部触碰终端触摸屏进行操作时，各自所对应触碰区域的形状和大小比较稳定，请同时参阅6，本发明触摸信号处理方法检测的触碰信号示意图。比如，稳定时触屏笔触碰所对应触碰区域标示为602，手指触碰所对应触碰区域标示603，手部触碰所对应触碰区域标示为601。一般，触屏笔触碰所对应触碰区域标示602和触碰所对应触碰区域标示603的形状规则、大小根据触碰力度不同在一定范围变化，触屏笔触碰所对应触碰区域602略小于手指触碰所对应触碰区域603，手部触碰区域形状根据手势变化，可有多个形状大小，但正常操作时也遵循一定规律，手部触碰区域601、手指触碰区域603和触屏笔触碰区域602的大小依序变小。其中手部是指手掌除去手指以外其他部分对应触碰区域，一般指手掌根部，即在进行触碰操作时，需要手掌根部支撑整个手掌，进而方便手指在触摸屏上进行触碰操作，类似于写毛笔字时的情形。
请参阅图1，图1是本发明触摸信号处理方法的第一实施方式的流程图。本 发明提供一种触摸信号处理方法，包括以下步骤：
S101：在检测到触碰动作时采集所述触碰动作所对应触碰区域的形状和/或大小的检测特征信息。
在点亮终端触摸屏时，用户通过手指、触屏笔和/或手部触碰终端触摸屏发生触碰动作，终端采集所有触碰动作所对应触碰区域的形状和/或大小的检测特征信息，并记录。
这里所检测到的检测特征信息，有可能是手指，也有可能是触屏笔，还有可能是手部。此时应用场景为单独用手指、触屏笔或手部触碰触摸屏操作。还可能是嘴唇、鼻子等。
S102：将检测特征信息和预置数据库中保存的标准特征信息进行比对。
将步骤S101记录的检测特征信息与终端数据库中预存的标准特征信息进行比对。其中，标准特征信息可自定义也可以出厂预置，包括手指或触屏笔触碰所对应触碰区域的形状和/或大小的手指特征信息，还包括手指以外手掌其他部分触碰区域的形状和/或大小的手部特征信息。
S103：如果比对的结果是检测特征信息与手指特征信息匹配，则进行对应手指特征信息的第一处理，如果比对的结果是检测特征信息与手部特征信息匹配，则进行对应手部特征信息的第二处理。
根据步骤S103的比对结果，如果对比结果是检测特征信息和终端数据库预存标准特征信息中的手指或触屏笔特征信息相同，则进行对应手指或触屏笔特征信息的第一处理；如果比对的结果是检测特征信息与终端数据库预存标准特征信息中的手部特征信息匹配，则进行对应手部特征信息的第二处理过程。其中，第一处理是正常的触摸响应处理，第二处理是忽略触碰动作，不响应手部触摸动作。
本实施例终端通过检测模块采集触碰动作所对应触碰区域的形状和/或大小的检测特征信息，然后将检测特征信息和预存终端里的标准特征信息进行对比，如果比对结果是检测特征信息和预存的标准特征信息匹配，则进行对应的处理。这样终端无需在触摸面板上进行专门的区域划分，只需要在触摸传感***中建立信号数据库，通过触碰信号和信号数据库比对，就能够完成相应的处理过程，提高了用户体验。
具体实施中预置标准特征信息还可只包括手指和/或触屏笔的特征信息，将检测到的触碰动作特征信息和预置标准特征信比对，如果比对结果是匹配，则 进行对应的手指和/或触屏笔特征信息的第一处理，如果不匹配，则进行第二处理。其中第一处理是正常的触摸响应处理，第二处理是忽略触碰动作，不进行处理。
请参阅图2，图2是本发明触摸信号处理方法的第二实施方式的流程图。本发明提供一种触摸信号处理方法，包括以下步骤：
S201：在检测到触碰动作时采集所述触碰动作所对应触碰区域的形状和/或大小的检测特征信息。
S202：将检测特征信息和预置数据库中保存的标准特征信息进行比对。
步骤S201至S202与前述实施方式步骤S101至S102相似，这里不再赘述。本实施例应用场景为手部和手指、手部和触屏笔同时触碰触摸屏。这里所检测到的检测特征信息，有可能是手指或触屏笔和手部。
S203：判断是否同时检测到匹配手指特征信息和手部特征信息的触碰动作。
根据步骤S202的比对结果判断终端是否同时检测到匹配手指特征信息和手部特征信息的触碰动作。
S204：如果同时检测到匹配手指特征信息和手部特征信息的触碰动作，则进行所述第一处理和/或所述第二处理，否则，不进行所述第一处理和/或所述第二处理并返回所述检测到触碰动作的步骤。
根据步骤S203的判断结果，如果终端同时检测到匹配手指特征信息和手部特征信息的触碰动作，则进行第一处理和/或第二处理，否则，不进行第一处理和/或第二处理并返回检测到触碰动作的步骤。其中手指特征信息包括手指和触屏笔的触摸特征信息。
本实施例在终端屏幕点亮时，终端通过检测模块采集触碰动作所对应触碰区域的形状和/或大小的检测特征信息，然后将检测特征信息和预存终端里的标准特征信息进行对比，判断是否同时检测到手指特征信息和手部特征信息的触碰动作，如果同时检测到手指特征信息和手部特征信息的触碰动作，且检测特征信息和预存的标准特征信息匹配(在检测特征信息和预存的标准特征信息进行比对前还可根据手指、手部和触屏笔的大小进行初步预判，触碰信号稳定时触碰区域形状最大的为手部触碰信息，然后依次为手指、触屏笔触碰信号)，则进行对应的第一处理和/或第二处理。如果没有同时检测到手指特征信息和手部特征信息的触碰动作，则不进行处理。如果同时检测到手部特征信息和多个手指和/或触屏笔特征信息，则按时间顺序，只将检测到的时间最早的手指和/或触 屏笔特征信息为有效触碰，这样终端只在手指特征信息和手部特征信息的触碰动作同时存在时，才处理和预存特征信息匹配且有效的触碰动作，避免了其他触碰动作引起误判。
请参阅图3，图3是本发明触摸信号处理方法的第三实施方式的流程图，本发明提供一种触摸信号处理方法，包括以下步骤：
S301：在检测到触碰动作时采集所述触碰动作所对应触碰区域的形状和/或大小的检测特征信息。
S302：将检测特征信息和预置数据库中保存的标准特征信息进行比对。
步骤S301至S302与前述第一实施方式中步骤S101至S102相似，这里不再赘述。本实施例应用场景为提高触碰信号的比对准确性，将稳定的触碰信号和预置标准触碰信号进行两次或两次以上的比对。
S303：等待预定时间返回所述检测到触碰动作的步骤，并重新执行所述将所述检测特征信息和预置数据库中保存的标准特征信息进行比对的步骤。
具体实施中，手部、手指、触屏笔触碰触碰区域，终端采集到触碰区域上触碰信号的形状和/或大小是随时间变化的，请同时参阅图4，图4是本发明触摸信号处理方法的第三实施方式在预定时间采集的一触碰信号大小随时间变化示意图。在时间为0的时刻没有发生触碰动作，时间为0到t1时刻开始发生触碰，t1时刻之前触碰动作刚开始发生，其触碰区域形状大小不稳定，t1时刻开始其触碰区域形状大小逐渐稳定，tn时刻结束触碰动作，假设预定时间设为t，在步骤S302中比对的触碰动作为t1时刻触碰动作，与t1时刻相隔预设时间t的t2时刻返回步骤S301重新检测触碰动作，并重新执行步骤S302将触碰信号稳定的t2时刻检测到的触碰动作和预置数据库中的标准特征信息进行比对。然后进入步骤S304。具体实施中还可继续两次以上比对步骤，即将在t2时刻相隔预设时间t的t3时刻的稳定触碰信号与预置数据库中的标准特征信息进行比对，为确保比对结果检测和比对的步骤可重复多次进行。
具体实施中为避免有时触碰动作的力度不同，导致采集的触碰动作检测特征信息大小和预置标准特征信息不完全一样，还可允许触碰动作特征信息在触碰区域形状相同情况下，触碰区域的大小可在一定范围内变化；或者在标准特征信息中同一触碰动作设定最大和最小形状，在检测特征信息稳定的情况下，如果其触碰区域形状与标准特征信息匹配，且检测特征信息中的大小在预置的最大、最小特征信息内，则比对结果为检测特征信息与标准特征信息匹配。
S304：如果比对的结果仍然是所述检测特征信息与手指特征信息匹配，才进行对应所述手指特征信息的第一处理，如果所述比对的结果仍然是所述检测特征信息与手部特征信息匹配，则进行对应所述手部特征信息的第二处理。
本实施例中终端通过前一次检测和比对后再进行后一次检测和比对，如果后一次比对的结果仍然是检测特征信息与手指特征信息匹配，才进行对应手指特征信息的第一处理，如果比对的结果仍然是检测特征信息与手部特征信息匹配，则进行对应手部特征信息的第二处理。终端通过两次或两次以上检测和比对的步骤，确保触碰动作和预存标准触碰特性信息相同，有效地避免了误判触碰动作。
请参阅图5，图5是本发明触摸信号处理方法的第四实施方式的流程图，本发明提供一种触摸信号处理方法，包括以下步骤：
S401：建立手部、手指、触屏笔触碰信号数据库。
打开终端建立标准触碰信号数据库***，分别用手、手指、触屏笔触碰触摸板，采集触碰区域的形状、大小特征信息，如图6所示，图6是本发明触摸信号处理方法检测的触碰信号示意图，图中包括手部触碰区域601、手指触碰区域603、触屏笔触碰区域602。基于触碰区域的形状、大小特征信息分别建立触手、手指、触屏笔触碰信号数据库为标准触碰信号数据库。
S402：检测触碰动作。
预设触碰动作检测时间段，在绘制输入过程中，在每个预设时间内采集每个触碰区域的形状、大小特征信息。这里采集的检测触碰信号为手指和/或触屏笔和/或手部触碰特征信息。
S403：产生触碰信号。
对在一个预设时间段内触碰区域的形状、大小特征发生变化的触碰动作形成基于触碰区域形状、大小特征信息的触碰信号。
S404：比对触碰信号。
根据采集触碰区域的形状、大小特征信息，将触碰信号和信号数据库进行比对。
S405：处理触碰信号。
根据用户的使用习惯，一般包括三种使用情形：一、手指或者触屏笔触碰触摸屏，类似于用手指触碰手机的情形；二、手指/触屏笔和手部触碰触摸屏，即在进行触碰操作时，需要手掌根部支撑整个手掌，进而方便手指在触摸屏上 进行触碰操作的情形；三、使用触屏笔、手指和手部触碰触摸屏，即手指夹住触屏笔，手部和手指触碰触摸屏支撑整个手掌，从而方便使用触屏笔操作，类似于写字时的情形。当根据触碰信号和信号数据库比对的结果，如果检测特征信息比对结果为与手指或者触屏笔触碰信号数据库匹配，即处于第一种应用情形，则进行第一处理过程；如果对比结果为与手指/触屏笔触碰信号和手部触碰信号数据库匹配，即第二种应用场景，则对与手指/触屏笔触碰信号匹配的触碰信号进行第一处理过程，对与手部触碰信号匹配的触碰动作进行第二处理过程；如果检测特征信息比对结果为手指、触屏笔、手部触碰信号与预置数据库都匹配，即处于第三种应用情形，则对触屏笔触碰信号进行第一处理过程，手指和手部触碰信号进行第二处理过程。其中第一处理过程是正常的触摸响应处理过程，第二处理过程为忽略触碰动作，不响应触摸动作。
请参阅图7，图7是本发明触摸信号处理设备的一实施方式的结构示意图。本发明提供一种触摸信号处理设备，包括：检测模块701、比对模块702、处理模块703、存储模块704。
检测模块701、比对模块702、处理模块703依序相连，其中存储模块704还分别与比对模块702、检测模块701相连。
检测模块701用于在终端屏幕点亮时，检测模块701检测触碰动作，并采集触碰动作所对应触碰区域的形状和/或大小的检测特征信息，并将采集的检测特征信息记录在存储模块704中，也可临时寄存在终端内存(图未示)中。
存储模块704用于存储预置标准特征信息的数据库。其中标准特征信包括手指或触屏笔触碰所对应触碰区域的形状和/或大小的手指特征信息，还包括手指以外手掌其他部分的形状和/或大小的手部特征信息。标准特征信息还可进行自定义或出厂预设。
比对模块702用于将检测模块701检测到的检测特征信息与存储模块704预置数据库中保存的标准特征信息进行比对。
本实施例终端通过检测模块701采集触碰动作所对应触碰区域的形状和/或大小的检测特征信息，然后将检测特征信息和存储模块704中预存的标准特征信息进行对比，如果比对结果是检测特征信息和预存的标准特征信息匹配，则处理模块703进行对应的处理。这样用户可无需刻意在特定区域分别摆放手部、手指、触屏笔，能随意摆放手部、手指、触屏笔，***能识别有效的触碰信号进行对应处理，提高了用户体验。
具体实施中处理模块703可以包括判断单元(图未示)，判断单元用于判断检测模块701是否同时检测到匹配手指特征信息和手部特征信息的触碰动作。如果检测模块701同时检测到匹配存储模块704中预置的手指特征信息和手部特征信息的触碰动作，则进行第一处理和/或第二处理，否则，不进行第一处理和/或第二处理。其中手指特征信息包括手指和触屏笔的触摸特征信息。判断单元判断是否同时检测到手指特征信息和手部特征信息的触碰动作，如果同时检测到手指特征信息和手部特征信息的触碰动作，且检测特征信息和预存的标准特征信息匹配，则处理模块703进行对应的第一处理和/或第二处理。如果没有同时检测到手指特征信息和手部特征信息的触碰动作，则不进行处理。这样终端只在手指特征信息和手部特征信息的触碰动作同时存在时，才处理和预存特征信息匹配且有效的触碰动作，提高了用户体验。
具体实施中还可以预设时间，在预设时间内将检测模块701检测到的检测特征信息和存储模块704中预存的标准特征信息进行二次对比，或两次以上比对，如果比对结果仍然是检测特征信息与手指特征信息匹配，才进行对应手指特征信息的第一处理，如果比对结果仍然是检测特征信息与手部特征信息匹配，则进行对应手部特征信息的第二处理。其中第一处理是正常的触摸响应处理，第二处理是忽略触碰动作，不响应手部触摸动作。
以上所述仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
