Description

一种用于屏幕显示设备的文字编辑方法及装置 技术领域
本申请涉及文字编辑技术，具体涉及一种用于屏幕显示设备的文字编辑方法。本申请同时提供一种用于屏幕显示设备的文字编辑装置。
背景技术
文字输入法是指为了将各种文字符号输入计算机或其他设备(如移动终端)而采用的编码方法。伴随着计算机和互联网技术的发展，用户对文字输入法的要求越来越高，在传统的键盘输入方式的基础上，先后出现了手写输入方式、光学字符识别OCR输入方式、以及语音输入等多种文字输入方式。
传统的键盘输入方式通过敲击键盘输入数字、字母以及符号，或者按照拼音规则输入汉字，是比较常用的文字输入方式；当遇到生僻字或者陌生字时，可以采用手写输入方式按照笔画进行文字的输入与识别；OCR输入则是通过电子设备(例如扫描仪或数码相机)检查纸上打印的字符，通过检测暗、亮的模式确定其形状，然后用字符识别方法将形状转换成文字；语音输入法是通过将说话者的语音转换成声音信号，与计算机等设备中已存储的已有声音信息进行比较，从而识别出声音信号对应的文字，该输入方法目前应用比较广泛。
当用户通过上述方式或者网络下载等其他方式得到了原始文字信息，经常还会因为各种原因需要对原始文字信息进行编辑，例如，采用语音输入转换得到的原始文字信息，由于技术层面的原因以及使用者发音不标准或者吐字不清等原因，导致语音输入转文字功能的正确率通常都达不到100％，尤其是在受到噪音等外界干扰的情况下，采用语音输入法转换得到的文字信息中的错误会更多。
在这种情况下，用户通常会再次采用传统的输入方式进行进一步的编辑修改，例如：采用键盘输入或者手写输入，用户需要逐一输入拼音字母或者笔画、并从输入法系统给出的多个候选项中挑选出符合意图的文字，而且手写输入还存在识别错误再次输入的可能性，因此整个编辑修改过程比较繁琐。特别是在手机等移动终端设备的物理键盘或者触摸屏显示的虚拟键盘上操作，由于按键 尺寸相对比较小，编辑修改过程更易出错，使得文字编辑效率低下，影响用户的使用体验。

具体实施方式
在下面的描述中阐述了很多具体细节以便于充分理解本申请。但是本申请能够以很多不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本申请内涵的情况下做类似推广，因此本申请不受下面公开的具体实施的限制。
在本申请中，分别提供了一种用于屏幕显示设备的文字编辑方法、和一种用于屏幕显示设备的文字编辑装置。在下面的实施例中逐一进行详细说明。
请参考图1，其为本申请的一种用于屏幕显示设备的文字编辑方法的实施例的第一流程图。所述方法包括如下步骤：
步骤S101：在屏幕显示设备的文字编辑区中显示原始文字信息。
本申请实施例的技术方案，根据用户在原始文字信息中选择的待修改文字，显示对应所述待修改文字的候选替代文字(也称为推荐词)，并使用用户选择的候选替代文字替代所述原始文字信息中的待修改文字，从而实现了基于智能推荐方式的文字编辑方法，能够提高文字编辑过程的准确率和操作效率。
由于语音输入转文字功能的正确率依然不足，而且由于移动终端设备尺寸的限制，通过键盘输入和手写输入等输入方式进行编辑都比较不方便，因此本申请实施例的技术方案应用于移动终端设备的语音输入转文字后的编辑操作中，有益效果更为明显。然而本申请实施例的技术方案并不局限于上述应用场景，对于在屏幕显示设备上显示的原始文字信息进行编辑通常都可以使用本申 请实施例的技术方案，例如在个人电脑、智能手机、IPAD设备等。
本申请实施例所述的原始文字信息，可以是通过语音输入、手写输入、键盘输入、或者光学字符识别OCR输入等方式生成的，也可以是采用其他方式获取的，对此本实施例的技术方案不作具体的限定。
为了对所述原始文字信息进行编辑，本步骤在屏幕显示设备的文字编辑区中显示待编辑的原始文字信息。考虑到采用触摸屏技术、并且显示屏幕尺寸比较有限的应用场景(例如，在智能手机上实施本技术方案)，如果将所述原始文字信息显示在系统缺省提供的文字编辑框中(例如通常使用的短信收发应用程序中的文字编辑框)，不便于用户通过对触摸屏的触控操作选择待修改文字，因此本申请实施例提供一种优选实施方式，即：在为了便于点击或者触控、而对文字的尺寸和间隔进行了优化设置的自定义文字编辑区域中显示所述原始文字信息。
在本实施例的一个具体例子中，在智能手机设备上实施本申请实施例的技术方案，没有采用系统默认的文字编辑框，而是根据该设备显示屏幕的分辨率自定义了一个视觉区域，具体实现时可以采用滚动视图scrollview控件，然后在该视觉区域中使用UILabel控件绘制特定大小的网格，所述网格的大小是根据预先设定好的显示文字的尺寸和间隔来设置的，在每一个网格中顺序显示所述原始文字信息中的每个汉字、字母、数字或者符号等。
请参见附图3，其为本申请实施例提供的自定义文字编辑区的效果示意图，其中301为本实施例自定义的文字编辑区。通过该图可以看出本实施例通过采用上述方式自定义文字编辑区，可以将原始文字信息以相对比较清晰的方式显示在屏幕上，从而便于用户通过对触摸屏的触控操作来选择需要修改的文字或者是光标插入位置。
步骤S102：接收对所述原始文字信息中待修改文字的选择。
如果在个人电脑设备上实施本申请实施例的技术方案，可以接收用户对键盘或鼠标的操作，从而获知用户所选的待修改文字；如果在具有触摸屏的智能手机或者IPAD等移动终端设备上实施本申请实施例的技术方案，则可以通过接收用户对触摸屏的触控动作，获知用户所选的待修改文字。
在本实施例的上述具体例子中，将用户对触摸屏的触控事件定义为三种类型：单击、长按、滑动，并通过系统API捕捉用户对触摸屏的触控事件，根据 事件类型、事件位置来执行相应的操作。在本步骤中仅仅涉及单击、滑动操作，长按操作的用途在后续段落叙述。
1)单击事件。根据事件位置参数来判断所述单击操作是否发生在所述文字编辑区的某一个网格区域中，如果是，则说明该网格区域显示的文字即为所述待修改文字，同时高亮显示该网格区域；
2)滑动事件。根据滑动事件状态定义三个阶段：开始、滑动中、结束，在开始时，记录开始位置对应的网格区域；在滑动过程中，通过事件位置添加或修改选中的网格区域；在滑动结束时，被选中的网格区域中包含的文字即为所述待修改文字，同时高亮显示被选中的网格区域。
步骤S103：从易混淆文字数据库中，获取对应所述待修改文字的候选替代文字。
本申请所述的易混淆文字数据库是指，通过收集易混淆文字、并对易混淆文字进行汇总、分类后，按照设计好的数据格式存储得到的数据库，使用特定文字在该数据库中执行查询操作，即可获取与所述特定文字对应的一项或者多项易混淆文字。根据收集易混淆文字时所依据的产生混淆的原因不同，所述易混淆文字数据库可以分为不同的种类，例如：发音易混淆文字数据库，其存储的就是发音相同或者相近的文字；字形易混淆文字数据库，其存储的就是字形相近的易混淆文字。在具体实施中，所述易混淆文字数据库可以是从服务端获取、并在本地存储的，也可以是仅在服务器端存储的，下面对这两种实施方式如何获取候选替代文字分别进行说明。
1)易混淆文字数据库是从服务端获取并在本地存储的。
首先根据所述原始文字信息的输入方式，选择对应的易混淆文字数据库。例如，原始文字信息是通过语音输入方式或者通过键盘以拼音方式输入的文字，可以选择发音易混淆文字数据库；原始文字信息是采用光学字符识别方式(OCR)或者手写输入方式得到的，则可以选择字形易混淆文字数据库。
选取了相应的易混淆文字数据库后，就可以根据所述待修改文字执行查询操作，获取对应所述待修改文字的易混淆文字。
作为一种相对简单的实施方式，可以直接将通过上述查询操作获取的易混淆文字作为候选替代文字在显示屏幕上显示。为了提高用户的选择效率，特别是在通过上述查询操作获取的易混淆文字比较多的情况下，可以对所述易混淆 文字进行进一步的筛选。具体说，根据所述待修改文字在所述原始文字信息中的上下文语境，选择在相同或者类似上下语境下匹配率相对比较高的易混淆文字，同时还可以兼顾考虑所述原始文字信息的应用场景，例如所述原始文字信息应用在电商平台的客户端APP中，那么就可以重点选择与电商交易相关的易混淆文字，并将通过上述过程筛选出的易混淆文字作为对应所述待修改文字的候选替代文字。
2)易混淆文字数据库是在服务端存储的。
由于所述易混淆文字数据库位于服务端，也就是说上面描述的选取数据库、查询、筛选等操作都可以交由服务端完成，这种情况下，客户端只需要执行下述操作：向所述服务端发送获取候选替代文字的请求，所述请求中至少包含所述待修改文字；接收所述服务端返回的对应所述待修改文字的候选替代文字。
在具体实施中，如果所述服务端存储了所述原始文字信息，例如，所述原始文字信息是在客户端采用语音输入方式输入、并且由服务端负责转换成原始文字信息并返回给客户端的，这种情况下服务端已经存储了所述原始文字信息，因此客户端可以在请求中仅携带待修改文字；如果所述服务端没有储存原始文字信息，则客户端还可以在请求中携带所述原始文字信息以及原始文字信息的获取方式，从而便于服务端进行相关的处理操作。
步骤S104：将所述候选替代文字显示在屏幕显示设备的推荐区。
将已经获取的候选替代文字显示在屏幕显示设备的推荐区，以便于用户从中选择所需的替代文字。请参见附图3，其中的302就是本实施例的具体例子中的推荐区，针对用户在文字编辑区中所选的待修改文字，在所述推荐区中显示了相应的候选替代文字。上述附图仅仅是示意性的，在具体的实施中，所述推荐区的位置、大小都可以根据具体情况设置。
步骤S105：接收对所述候选替代文字的选择。
此步骤与步骤S102类似，可以通过监控鼠标的点击操作或者是用户对触摸屏的触控操作，根据点击或者触控操作的位置信息，判断是否是对推荐区中的某个候选替代文字的点击或触控操作，若是，则所述候选替代文字即为用户选中的替代文字。
步骤S106：以被选择的候选替代文字替代所述原始文字信息中的所述待修改文字。
用步骤S105中选中的候选替代文字替代所述原始文字信息中的所述待修改文字，同时还应该在文字编辑区中显示执行了上述替代操作的原始文字信息。在本实施例所述的具体例子中，如果步骤S105中选中的候选替代文字与所述待修改文字的字数相同，则直接将所述候选替代文字逐字显示在所述待修改文字所在的网格区域中即可，如果所述候选替代文字与所述待修改文字的字数不同，则还需要调整所述待修改文字之后的部分原始文字信息在文字编辑区中的显示。
上面描述了通过智能推荐方式对于待修改文字进行替换编辑的过程，之所以将上述处理过程称为是一种智能推荐方式，是因为该过程的实现不需要用户通过人工方式输入所需的替换文字，而是由本实施例提供的方法自动获取对应待修改文字的候选替代文字并在界面上推荐给用户，从而用户只需要从所述候选替代文字中做出选择就可以完成替换操作。
在具体的实施过程中，可能存在这样两种情况：在易混淆文字数据库中没有找到对应于所述待修改文字的候选替代文字，或者推荐区中显示的候选替代文字都不满足用户的要求。在上述两种情况下，通常就不会接收到对所述候选替代文字的选择，因此不会触发步骤S105和步骤S106的执行。本实施例的技术方案提供了其他的输入方式，以便用户输入自己所需的替代文字。该过程包含步骤S107-步骤S108，下面对这两个步骤进行说明。
步骤S107：接收通过人工输入方式输入的文字，作为人工输入替代文字。
在屏幕显示设备的显示界面上为用户提供利用人工输入方式进行输入的接口，并根据用户的选择接收相应的输入文字。所述人工输入方式包括：语音输入、键盘输入、或手写输入等。
例如，在界面上显示用于执行语音输入操作的按钮，如果接收到对该按钮的点击或者触控操作，则开始接收用户的语音输入信息，当检测到语音输入的停顿时间超过预先设定的阈值或者检测到对停止语音输入按钮的点击或者触控操作时，终止语音输入过程，并将输入的语音信息转换成文字，即得到本步骤所述的人工输入替代文字。
在具体实现中，语音录制过程可以通过调用AVAudioRecorder类提供的相关函数或者接口实现，然后将生成的AMR语音文件通过HTTP协议或者采用其他方式发送给负责将语音转换成文字的服务端进行处理，服务端通过滤除噪音、 特征提取、模型匹配等技术将语音转换成文字并返回给客户端。语音转换文字的技术相对成熟，例如安卓提供了Speech To Text的开源实现，本领域的技术人员可以参考实现。
除了上述语音输入方式以外，还可以通过接收键盘输入的方式获取所述人工替代文字。例如，对于个人电脑，监控并接收键盘的输入，即可获取用户输入的替代文字，对于智能手机等移动终端，则可以在界面上显示用于执行键盘输入操作的按钮，如果接收到对该按钮的点击或者触控操作，则调出系统缺省的虚拟键盘供用户进行文字输入，当然也可以在推荐区显示候选替代文字的同时，自动调出系统缺省的虚拟键盘供用户使用。在具体实现中，可以调用系统提供接口实现虚拟键盘的调用，例如在ios平台上可以调用becomefirstresponder()函数调出虚拟键盘。
上面的例子都是示意性的，在具体实施中，可以根据需要在显示界面上提供相应的人工输入接口，并且可以采取不同的触发方式调用所述人工输入方式，只要能够获取用户通过人工输入方式输入的文字(即：人工输入替代文字)即可。
步骤S108：用所述人工输入替代文字替代所述原始文字信息中的所述待修改文字。
在步骤S107中获取了人工输入替代文字，在本步骤中用该文字替代所述原始文字信息中的所述待修改文字，并采用与步骤S106类似的方式，更新在文字编辑区中显示的原始文字信息。
通过上述步骤S107-S108的处理，在没有候选替代文字被选择的情况下，用通过其他输入方式获取的文字替代了所述待修改文字。用户没有在候选替代文字中做出选择(或者推荐区中没有显示候选替代文字)，说明所述易混淆文字数据库中对应所述待修改文字的易混淆文字还不够完善，为了能够丰富、完善所述易混淆文字数据库中的数据，以便更有效地为用户提供候选替代文字，本实施例提供了所述易混淆文字数据库的自学习功能，即：将所述人工输入替代文字更新到所述易混淆文字数据库中，作为与所述待修改文字对应的一条易混淆文字项。
如果所述易混淆文字数据库在服务端存储，则可以通过HTTP协议或者其他方式将所述待修改文字和对应的人工输入替代文字发送给所述服务端，服务 端可以采用自己的策略判断是否需要更新相关的数据并进行相应的处理。
如果所述易混淆文字数据库是从服务端获取、并在本地存储的，则可以直接针对本地的数据库进行数据更新操作，将所述人工输入替代文字作为所述待修改文字的一条易混淆文字项，添加到本地数据库中。
此外，对于所述易混淆文字数据库在本地存储的情况，还可以将更新后的数据库数据上传到服务端，供所述服务端进行汇总和/或共享。在具体实现中，可以采用不同的策略设定上传数据的时机和数据量，例如，可以实时地、或者定期地进行上传，每次上传也可以选择上传本地的易混淆文字数据库的全量数据或者仅仅是最近更新的增量数据。服务端可以依据自己的策略对接收到的上述数据进行汇总，并可以共享汇总后的数据库供客户端下载使用。采用上述方式，通过将系统内每个客户端的自学习成果汇总并共享，有助于提高整个系统内的智能推荐的有效性。
上述步骤描述了对所述待修改文字的替代操作，本实施例的技术方案还可以支持对所述待修改文字的删除操作，该处理过程包括步骤S109-S110，下面对这两个步骤进行说明。
步骤S109：接收对用于执行删除操作的实体按键或者虚拟按键的点击或触控操作。
本步骤所述的实体按键是指实体键盘上的按键，例如：个人电脑键盘上的按键、移动终端设备在显示屏下方提供的实体键盘上的按键、菜单键、确认键等，以及移动终端设备的侧键等；本步骤所述的虚拟按键通常是指在显示屏幕上显示的虚拟键盘上的按键以及虚拟按钮。
在不同的应用场景下，对上述按键的点击或者触控操作会触发执行不同的功能。在本步骤中通过监控用户的点击操作以及对触摸屏的触控操作，判断被点击或者触控的是否为用于执行删除操作的实体按键或者虚拟按键，如果是，则执行后续步骤S110。
步骤S110：从所述原始文字信息中删除所述待修改文字。
从所述原始文字信息中删除所述待修改文字后，相应的，在文字编辑区中更新显示执行了删除操作后的原始文字信息。
作为一种完善的文字编辑方法，可以具有上述步骤S101-S110描述的、针对已选择的文字执行替换、删除的功能，还可以具有根据用户选择的插入位置执 行文字插入、文字删除，以及清除所有原始文字信息和确认结束本次编辑这四种功能，由于这四种功能是文字编辑方法通常都具备的功能，因此下面结合附图2，对上述功能的实现作简要说明。
执行步骤S101在屏幕显示设备的文字编辑区中显示所述原始文字信息后，基于所选插入位置的文字插入处理流程包含下述步骤S201-步骤S203。
步骤S201：接收对所述原始文字信息中的插入位置的选择。
可以预先设定代表选择插入位置的操作方式，当在所述文字编辑区中检测到所述操作方式时，即为接收到了用户对插入位置的选择。
在本实施例的一个具体例子中，将用户对触摸屏的触控事件定义为三种类型：单击、长按、滑动，并通过系统API捕捉用户对触摸屏的触控事件，其中对单击事件和滑动事件的处理，请参见步骤S102中的描述。在本步骤中，因为预先设定了长按事件代表用户对插入位置的选择，因此根据检测到的长按事件的位置参数来判断用户是否在某一个网格区域中执行了长按操作，如果是，则说明文字插入位置位于该网格区域所对应文字与下一个网格区域对应文字之间，并在该网格区域右侧边缘绘制一个高亮闪烁的竖条，以提示用户当前选择的插入位置。
步骤S202：接收通过人工输入方式输入的文字。
在屏幕显示设备的显示界面上为用户提供利用人工输入方式进行输入的接口，并根据用户的选择接收相应的输入文字。该步骤与步骤S107类似，详细描述信息请参见步骤S107的相关部分。
步骤S203：将通过上一步骤获取的文字插入到所述原始文字信息中的所述插入位置处。
将步骤S202获取的文字插入到所述原始文字信息中的相应插入位置处，相应的，在文字编辑区中更新显示执行了插入操作后的原始文字信息。
执行步骤S101在屏幕显示设备的文字编辑区中显示原始文字信息后，基于所选插入位置的文字删除流程包含步骤S204-步骤S206：
步骤S204：接收对所述原始文字信息中的插入位置的选择。
本步骤与步骤S201基本相同，请参见步骤S201的相关描述。
步骤S205：接收对用于执行删除操作的实体按键或者虚拟按键的点击或触控操作；
关于实体按键以及虚拟按键的说明请参见步骤S109中的相关部分。
在本步骤中通过监控用户的点击操作以及对触摸屏的触控操作，判断被点击或者触控的是否为用于执行删除操作的实体按键或者虚拟按键，如果是，则执行后续步骤S206。
步骤S206：从所述原始文字信息中删除位于所述插入位置之前或者之后的文字。
在具体的实现过程中，可以预先设置用于执行删除操作的多个实体按键或者虚拟按键，并且为不同的按键定义不同的操作方式，例如，传统的虚拟键盘上的删除键通常删除位于插入位置之前的文字，而实体键盘上的删除键(delete键)通常删除位于插入位置之后的文字。本步骤则根据接收到的实体按键或者虚拟按键对应的不同操作方式，从所述述原始文字信息中删除位于所述插入位置之前或者之后的文字。
与之前的编辑操作类似，执行上述删除操作后，在文字编辑区中更新显示执行了删除操作后的原始文字信息。
执行步骤S101在屏幕显示设备的文字编辑区中显示原始文字信息后，清除所有原始文字信息的处理流程包含下述步骤S207-步骤S208。
步骤S207：接收对用于执行清除操作的实体按键或者虚拟按键的点击或触控操作。
关于实体按键以及虚拟按键的说明请参见步骤S109中的相关部分。
在本步骤中通过监控用户的点击操作以及对触摸屏的触控操作，判断被点击或者触控的是否为用于执行清除操作的实体按键或者虚拟按键，如果是，则执行后续步骤S208。
步骤S208：清除原始文字信息，并返回到进行文字编辑之前的状态。
本步骤所述的清除操作，是指删除全部的原始文字信息，相应的也要清空在文字编辑区中显示的原始文字信息，并返回到进行文字编辑之前的状态。
执行步骤S101在屏幕显示设备的文字编辑区中显示原始文字信息后，确认完成本次编辑的处理流程包含步骤S209-步骤S210。
步骤S209：接收对确认完成本次编辑操作的实体按键或者虚拟按键的点击或触控操作。
关于实体按键以及虚拟按键的说明请参见步骤S109中的相关部分。
在本步骤中通过监控用户的点击操作以及对触摸屏的触控操作，判断被点击或者触控的是否为用于确认完成本次编辑操作的实体按键或者虚拟按键，如果是，则执行后续步骤S210。
步骤S210：执行相应的完成操作，所述完成操作包括：保存操作或发送操作。
根据步骤S209接收到的点击或者触控操作，执行相应的完成操作。根据本申请提供的文字编辑方法的应用场景不同，本步骤执行的所述完成操作可能是不同的，例如在常规的文字编辑应用中，通常会保存编辑完毕的原始文字信息；而在一些即时通讯应用中，则可以直接发送编辑完毕的原始文字信息。在具体的实施方式中，本步骤还可能执行不同于上述操作的代表本次编辑完成的其他操作。
以上描述了本实施例技术方案提供的用于屏幕显示设备的文字编辑方法的处理流程。需要说明的是，其中的步骤S101-S106是本技术方案的核心，通过这几个步骤，就可以实现根据智能推荐词替换待修改文字的编辑操作。而其他步骤则是为了给用户提供不同的文字输入方式或者是其他的编辑操作方式，并不是实现本技术方案必需的步骤，在具体实施时，可以根据需要进行选择或者调整。
本申请提供的用于屏幕显示设备的文字编辑方法，用从易混淆文字数据库中获取对应所述待修改文字的候选替代文字，替代所述原始文字信息中的所述待修改文字，避免了传统人工输入方式操作繁琐、易出错的问题，用户仅需选择待修改文字、并从候选替代文字中选择所需的替代文字就可以完成编辑操作，提高了文字编辑过程的准确率和操作效率，减少用户的编辑时间。特别是应用于移动终端的语音输入转文字后的编辑操作中，更能有效改善用户的使用体验。
