Description

一种手写输入方法及装置 技术领域
本申请涉及但不限于终端领域，尤其是涉及一种手写输入方法及装置。
背景技术
随着移动终端的快速发展，触摸屏被大量使用，随之兴起的是基于触摸屏的手写汉字输入技术。相对于主流的基于虚拟键盘的拼音输入法，手写输入的主要优势是：无需拼音基础，也无需掌握汉字的准确发音，利于未接受过拼音教育的老年人和普通话不好的方言人群使用。
但是，手写输入法也有自身的缺陷。其中主要的缺陷是：汉字的平均笔划数较多，导致手写输入法的输入效率比拼音输入法低。根据统计结果，常用简体汉字的平均笔划数，大约是每汉字10个笔划，而港台等繁体汉语区的汉字笔划数更多。例如，很常用的汉字如“霸”和“罐”，其笔划数量超过20，远超拼音输入法的平均3个字母的拼音长度。
对于笔划偏多的文字来说，不仅导致手写环节效率的下降，在一些小型的触摸屏如智能手表上，偏多的笔划还会导致用手写输入时，不仅笔划短小，笔划间的相对位置也难以准确表达，甚至可能导致机器无法识别的问题。
发明内容
以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求的保护范围。

在一种示例性实施方式中，确定包含第一文字的第二文字，包括：在预先建立的发音同源字列表中查找与第一文字属于同一组发音同源字的第二文字，或，在预先建立的第一列表中查找使用第一文字作为偏旁部首的第二文字。
在一种示例性实施方式中，上述方法还包括：在对输入的文字笔划进行识别，得到第一文字之后，接收外部输入的文字选择指令；当文字选择指令是预设类型的指令时，执行确定与第一文字读音相关或包含第一文字的第二文字，以及在待选文字区域显示第二文字的步骤，否则在待选文字区域显示与第一文字字形类似的第三文字。

在一种示例性实施方式中，上述装置还包括：建立模块，设置为：在对输入的文字笔划进行识别，得到第一文字之前，预先建立发音同源字列表，在列表中，使用相同声旁的文字属于同一组发音同源字。

本发明的较佳实施方式
下面结合附图对本发明的实施方式进行描述。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的各种方式可以相互组合。
第一实施例
本实施例提供了一种手写输入方法，该方法可以集成在触摸屏终端设备上，图1是该方法的流程图，如图1所示，该方法包括：
步骤101：对输入的文字笔划进行识别，得到第一文字；
该步骤中，可以使用相关技术中的手写输入方法中的对笔划的识别方式来得到第一文字，例如，可以是对预设时间段内接收到的用户输入的笔划进行识别，得到第一文字。
步骤102：确定与第一文字读音相关或包含第一文字的第二文字；
在该步骤中，确定与第一文字读音相关或包含第一文字的第二文字可以包括：
确定与第一文字读音相同的第二文字，或，在预先建立的发音同源字列表中查找与第一文字属于同一组发音同源字的第二文字，或，在预先建立的第一列表中查找使用第一文字作为偏旁部首的第二文字。
其中，本实施例中，与第一文字读音相关的第二文字可以包括多个，同理包含第一文字的第二文字也可以为多个，基于此，在步骤103中，在待选文字区域可以显示该多个第二文字，以供用户选择。其中，包含第一文字的第二文字可以是，第一文字的发音同源字，或以第一文字为偏旁部首的文字。
此处，确定与第一文字读音相同的第二文字可以是使用相关技术中的拼音输入法中根据读音来在字库中查找文字的方法来执行，故此处不再赘述。
基于此，本实施例提供的方法还可包括：在对输入的文字笔划进行识别，得到第一文字之前，预先建立发音同源字列表，在列表中，使用相同声旁的文字属于同一组发音同源字。
步骤103：在待选文字区域显示第二文字，以供用户选择。
可以说明的是，在本实施例中，可以根据用户输入的指令来确定是否触发执行本发明实施例提供的方法，基于此，上述方法还可包括：在对输入的文字笔划进行识别，得到第一文字之后，接收外部输入的文字选择指令；当文字选择指令是预设类型的指令时，执行确定与第一文字读音相关或包含第一文字的第二文字，以及在待选文字区域显示第二文字的步骤，否则可在待选文字区域显示与第一文字字形类似的第三文字，此处，该预设类型的指令可以是用户长按终端上呈现的第一文字，或用户点击某一按钮/虚拟按钮；在未接收到用户输入的预设类型的指令时，可执行相关技术中手写输入法中在 接收到用户输入的笔划后，查找并显示待选文字的操作；此外，不同类型的指令或，同类型的不同指令，可以分别对应着确定与第一文字读音相关的第二文字，以及包含第一文字的第二文字的操作，基于此，在用户输入不同类型的指令时，即可以实现不同的查找待选文字的方法。
可以说明的是，在本实施例中，确定与第一文字读音相关的第二文字可以是按照文字的常用频率来从与第一文字读音相关的所有文字中优先选择较为常用的文字作为本实施例所述的第二文字，同时，在待选文字区域显示该第二文字时，可以按照文字的常用频率从高到低的顺序来显示该第二文字。
本实施例提出的方法可以改善因为汉字笔划太多导致的输入效率和识别准确率的下降问题，提高了手写输入法的效率以及文字识别的准确率。
第二实施例
本实施例提供了一种手写输入方法，图2是该方法的流程图，如图2所示，该方法包括如下处理：
在相关技术中的手写输入法的界面上，当用户完成一个汉字的书写后，长按选择框中的某个汉字，可以触发出同音字选择功能。该功能被触发后，可根据内置的同音字总表，在屏幕上显示出对应汉字的同音字以供用户选择。利用上述相关技术中的方法，当用户遇到笔划复杂的汉字时，可以先书写一个笔划简单的同音字或者发音同源字，然后再利用设备的同音字或发音同源字选择功能，实现笔划复杂汉字的高效率输入。
以下通过一个应用实例来对本实施例提供的手写输入方法进行说明，该实例中以同音字为例进行说明。
以输入汉字“瀚”为例，结合附图2的输入流程，进一步说明手写结合同音字选择的输入方法。
当用户需要手写输入汉字时，可以先提前预判汉字笔划，决定是否要用同音字替代。“瀚”属于笔划较多的汉字，用户很容易想到其笔划较少的常用同音字是“汉”或者“汗”。
假定用户输入了“汉”，则屏幕出现的输入选择区可以包含数个字形跟汉接近的字，如附图3所示。
在待选文字区域，第一个字就是用户要输入的“瀚”字的同音字“汉”， 用户长按“汉”，输入区会切换到同音字选择框，并在汉字字库中检索出“汉”字的读音“han”，然后检索出所有发音为“han”的字并显示在该选择框中，如附图4所示。
相应地，用户可以找到要输入的字(第2行第7列)，并点击完成输入。
相关技术中的手写输入法和本实施例的输入法，输入“瀚”的效率对比如下表1所示：
表1
Figure PCTCN2017091703-appb-000001
可以说明的是，本实施例所描述的同音字选择方法，如附图2所示，在输入比较简单的汉字时，直接手写即可，不必通过长按触发同音字选择功能，对输入效率没有任何影响。即使对于笔划复杂的汉字，用户也可以完全沿用以前的输入习惯，不会有任何困扰。
本实施例提出的方法在相关技术中的手写输入法的界面上，增加同音字/发音同源字的触发功能，用户通过触发该功能，可以选择出与所书写汉字的读音相关的文字。这样，当需要输入一个笔划复杂的汉字时，用户可以用笔划简单的同音字替代，然后再选择它的同音字，完成所需汉字的输入，以提高输入效率。
第三实施例
本实施例以发音同源字为例，对本发明实施例提供的手写输入方法进行说明。
从上述实例可以看到，由于汉字的同音字较多，往往一个读音会对应数十个汉字，在这么多汉字里面选择一个汉字，则耗费时间较多。为了进一步提高效率，可以使用发音同源字代替同音字，以减少选项，提高效率。
所谓的发音同源字，是指根据汉字造字法中的形声字规则，使用相同声旁的汉字。例如，以汉字“正”为声旁的汉字可包括：正、整、征、证、怔、 政、症，这些字都是发音同源字。
相关技术中的汉字字库中，并未包含发音同源字的信息，因此，需要预先建立一个发音同源字总表，示例如下表2，表2中仅列出了3组发音同源字作为示例。

可以特别说明的是，由于汉字的读音在长期的演化过程中会发生一些变化，发音同源的汉字并非都是严格的同音字。例如下面这组汉字：“娇”，“骄”，“轿”,“矫”，“乔”，“桥”，“侨”，“荞”，“峤”，属于发音同源字，但有的读“jiao”，有的读“qiao”。
本实施例使用发音同源字，可进一步提高输入效率。其基本输入流程与第二实施例中的同音字选择方法类似，仅仅是给出的预选汉字有差异。下面以输入汉字“整“为例进行说明。
当用户需要输入汉字“整”时，提前会预判到此字的笔划很多，为了提高效率需要用同源字替代。整是个形声字，其最简单的发音同源同音字是“正”，而且“正”是“整”字按照形声造字法的声旁，容易被用户想到。
假定用户输入了“正”，则屏幕出现的输入选择区包含了数个字形跟“正”比较接近的字，如附图5所示。
在附图5中，待选文字区域第一个字就是我们要输入的“整”字的发音同源字“正”，用户长按“正”后，输入区切换到发音同源字选择框，显示出以“正”为声旁的发音同源字如附图6。
在附图6中，很容易找到“整”在第1行第2列，点击即可输入。
使用手写输入法和本实施例的输入法，输入“整”的效率对比如下表3 所示：
表3

可以看到，由于发音同源字通常少于同音字，在最后的选字环节(通过点击)，找出“整”的速度会更快。
可选地，除了同音字和发音同源字之外，还可以显示出使用当前汉字作为部首的汉字等。
第四实施例
本实施例提供了一种手写输入装置，图7是该装置的结构框图，如图7所示，该装置70包括：
识别模块71，设置为：对输入的文字笔划进行识别，得到第一文字；
确定模块72，设置为：确定与第一文字读音相关或包含第一文字的第二文字；
显示模块73，设置为：在待选文字区域显示第二文字，以供用户选择。
可选地，在本实施例中确定模块是设置为：确定与第一文字读音相同的第二文字，或，在预先建立的发音同源字列表中查找与第一文字属于同一组发音同源字的第二文字，或，在预先建立的第一列表中查找使用所述第一文字作为偏旁部首的第二文字。
可选地，上述装置70还可以包括：
建立模块，设置为：在对输入的文字笔划进行识别，得到第一文字之前，预先建立发音同源字列表，在列表中，使用相同声旁的文字属于同一组发音同源字。
可选地，本实施例提供的装置还可以包括：
接收模块，设置为：在对输入的文字笔划进行识别，得到第一文字之后，接收外部输入的文字选择指令；
执行模块，设置为：当文字选择指令是预设类型的指令时，执行确定与第一文字读音相关或包含第一文字的第二文字；以及在待选文字区域显示第二文字的步骤，否则在待选文字区域显示与第一文字字形类似的第三文字。
可以说明的是，该手写输入装置是与上述手写输入方法相对应的装置，其中上述方法实施例中所有实现方式均适用于该装置的实施例中，也能达到同样的技术效果。
第五实施例
本发明实施例还提供了一种计算机可读存储介质，存储有计算机可执行指令，所述计算机可执行指令被执行时实现上述手写输入方法。
本发明实施例提供的方案提高了普通终端上手写汉字的输入效率；同时，因老年人拼音基础普遍较差，老人手机纳入此功能后，则方便了使用；此外，在某些小屏幕设备如智能手表上，普通的手写输入无法适用，但本改进方案可用。
本领域普通技术人员可以理解上述实施例的全部或部分步骤可以使用计算机程序流程来实现，所述计算机程序可以存储于一计算机可读存储介质中，所述计算机程序在相应的硬件平台上(如系统、设备、装置、器件、处理器等)执行，在执行时，包括方法实施例的步骤之一或其组合。
可选地，上述实施例的全部或部分步骤也可以使用集成电路来实现，这些步骤可以被分别制作成一个个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。
上述实施例中的装置/功能模块/功能单元可以采用通用的计算装置来实现，它们可以集中在单个的计算装置上，也可以分布在多个计算装置所组成的网络上。
上述实施例中的装置/功能模块/功能单元以软件功能模块的形式实现并作为独立的产品销售或使用时，可以存储在一个计算机可读取存储介质中。上述提到的计算机可读取存储介质可以是只读存储器，磁盘或光盘等。
本领域的普通技术人员可以理解，可以对本申请的技术方案进行修改或 者等同替换，而不脱离本申请技术方案的精神和范围。本申请的保护范围以权利要求所定义的范围为准。
工业实用性
本发明实施例提出的方案在相关技术中手写输入法的界面上，增加另一种手写输入识别功能，用户通过触发该功能，可以选择出与所书写汉字的读音相关的文字或包含用户所书写的汉字的汉字。这样，当需要输入一个笔划复杂的汉字时，用户可以用笔划简单的同音字替代，然后再选择它的同音字，完成所需汉字的输入，以提高输入效率。
