The present invention relates to a rapid input method convenient to modify for a handwriting input device. When continuously inputted in an existing handwriting input device, the multiple characters (or words) cannot be accurately segmented and processed. Therefore, the rapid input method convenient to modify for handwriting input device in the present invention divides the current input area into the current sub-input area and the next sub-input area by adding a dynamic separator, wherein the length of the current sub-input area can be continuously extended as needed, and the next sub-input area can be continuously shifted rightwards. If a user requires, the characters just completed can be processed in the background as long as a pen tip or a finger crosses the dynamic separator to enter the next sub-input area. The present invention has the advantages of few steps, high speed and high efficiency, and is suitable for processing character literals such as Chinese, Japanese, Korean and so on, and is also suitable for processing the alphabetic literals such as English, French, Germany and the like, as well as all kinds of punctuation marks. The method is applicable to all kinds of terminal devices supporting external input such as personal computers, intelligent mobile phones, handheld computers and the like.

Description

便于修改的手写输入设备快速输入法Easy to modify handwriting input device fast input method 技术领域Technical field
本发明涉及一种便于修改的手写输入设备快速输入法，具体涉及一种在手写输入设备上通过增设动态分隔符来间隔字符，借以提高手写输入速度和识别准确度的方法。The invention relates to a quick input method for a handwriting input device which is easy to modify, and particularly relates to a method for spacing characters by adding a dynamic separator on a handwriting input device, thereby improving handwriting input speed and recognition accuracy.
背景技术Background technique
近年来，手写输入已广泛应用于移动电话、掌上电脑等移动设备，现有大部分的手写输入设备是让用户每次书写一个文字(或单词)，再通过内部的识别系统将手写的文字(或单词)转换为手机可识别的标准字体显示在手机屏幕上。但是此种方式的缺点是手写时一次只能输入一个文字(或单词)，并且必须停顿下来等待文字识别，无法不间断书写，也无法保存手写输入的原笔迹。In recent years, handwriting input has been widely used in mobile devices such as mobile phones and handheld computers. Most of the existing handwriting input devices allow users to write a text (or word) each time, and then handwritten text through an internal recognition system ( Or word) converted to a standard font recognized by the phone on the phone screen. However, the disadvantage of this method is that only one text (or word) can be input at a time when handwriting, and it is necessary to pause for text recognition, unable to write without interruption, and cannot save the original handwriting input by handwriting.
为了改善用户体验，有的手写输入设备开始支持多文字(或多单词)连续书写输入。这种技术不需要等待系统对单个文字(或单词)进行识别，能一次连续输入多个文字(或单词)，手写速度大大提高。但是现有技术也有一个缺陷：连续输入多个文字(或单词)时无法准确地将手写输入分割成单个文字(或单词)。这会导致在进行文字识别时将多个文字作为一个文字进行识别，或者将多个单词作为一个单词进行识别，进而不能正确识别。如果输入设备不进行文字识别，而是将多个字符缩小成一个图像保存在文件中，在编辑文件时多个文字(或单词)只能作为一个单元处理，而不是作为多个单元处理。In order to improve the user experience, some handwriting input devices begin to support multi-text (or multi-word) continuous writing input. This technique does not require the system to recognize a single word (or word), and can input multiple words (or words) at a time, and the handwriting speed is greatly improved. However, the prior art also has a drawback: it is not possible to accurately divide the handwriting input into a single character (or word) when continuously inputting a plurality of characters (or words). This causes multiple characters to be recognized as one word when text recognition is performed, or multiple words are recognized as one word, and thus cannot be correctly recognized. If the input device does not perform text recognition, but reduces multiple characters into one image and saves them in a file, multiple words (or words) can only be processed as one unit when editing the file, rather than being processed as multiple units.
发明内容Summary of the invention
本发明要解决的问题是如何克服现有技术的上述缺陷，提供一种便于修改的手写输入设备快速输入法。The problem to be solved by the present invention is how to overcome the above-mentioned drawbacks of the prior art, and provide a quick input method for handwriting input devices that is easy to modify.
本发明便于修改的手写输入设备快速输入法，包括下述步骤：The invention facilitates the modification of the handwriting input device fast input method, comprising the following steps:
(1)在触屏输入装置上定义坐标系；(1) defining a coordinate system on the touch screen input device;
(2)通过坐标将触屏分成M个显示行，手写输入时，其中一显示行处于激活状态，为当前显示行，当前显示行内设有当前显示格和待显示格，上次手写信息在当前显示格内显示，即将输入的信息将在待显示格内显示，同时将触屏区域分为N个输入区域，至少一个输入区域为当前输入区域；(2) Dividing the touch screen into M display lines by coordinates. When the handwriting is input, one of the display lines is in the active state, which is the current display line. The current display line has the current display grid and the to-be-displayed grid. The last handwritten information is in In the current display grid, the information to be input will be displayed in the grid to be displayed, and the touch screen area is divided into N input areas, and at least one input area is the current input area;
(3)当前输入区域内设有动态分隔符，该动态分隔符与当前输入区域左边侧保持A个横轴单位；动态分隔符左侧为当前子输入区，动态分隔符右侧为下一子输入区， (3) There is a dynamic separator in the current input area. The dynamic separator maintains A horizontal axis unit with the left side of the current input area; the left side of the dynamic separator is the current sub-input area, and the right side of the dynamic separator is the next sub-field. Input area,
①.每次手写输入时，触屏输入装置的处理部件首先判断在预定时间T内，当前输入区域是否有新的轨迹点输入：1. Each time the handwriting is input, the processing component of the touch screen input device first determines whether there is a new track point input in the current input area within a predetermined time T:
若超过预定时间T，当前输入区域仍没有新轨迹点输入，判断本次手写输入结束，If the predetermined time T is exceeded, there is still no new track point input in the current input area, and it is judged that the handwriting input ends.
②.触屏输入装置的处理部件将当前子输入区内的手写影像作为整体存贮，识别后或按比例缩小后显示在待显示格内，该待显示格转化为当前显示格，并在其右侧生成新的待显示格，具体表现为当前显示格和待显示格右移；同时将当前子输入区内的影像清空和/或将动态分隔符转化为静态分隔符，并在其右侧依次生成新的当前子输入区、新的动态分隔符和新的下一子输入区，具体表现为当前子输入区、动态分隔符和下一子输入区右移，然后返还第①步；2. The processing component of the touch screen input device stores the handwritten image in the current sub-input area as a whole, and after being recognized or scaled down, displayed in the to-be-displayed cell, the to-be-displayed cell is converted into the current display cell, and A new to-be-displayed cell is generated on the right side, which is represented by the current display cell and the right to be displayed cell; the image in the current sub-input area is cleared and/or the dynamic delimiter is converted into a static delimiter, and on the right side thereof A new current sub-input area, a new dynamic delimiter, and a new next sub-input area are sequentially generated, as follows: the current sub-input area, the dynamic delimiter, and the next sub-input area are shifted to the right, and then the first step is returned;
若在预定时间T内，当前输入区域内有新轨迹点输入，则进一步判断该新轨迹点位于动态分隔符左侧还是右侧，即判断新轨迹点位于当前子输入区还是位于下一子输入区，If there is a new track point input in the current input area within the predetermined time T, it is further determined whether the new track point is located to the left or the right of the dynamic separator, that is, whether the new track point is located in the current sub-input area or in the next sub-input. Area,
若新笔划位于动态分隔符右侧，即新轨迹点位于下一子输入区，则返还第②步；If the new stroke is located to the right of the dynamic separator, that is, the new track point is located in the next sub-input area, then return to step 2;
若新笔划位于动态分隔符左侧，即新轨迹点位于当前子输入区，则判定本次手写输入尚未结束，所述触屏输入装置的处理部件不断找出当前子输入区内最靠右的轨迹点，并使动态分隔符不断右移，确保动态分隔符与当前子输入区最靠右的轨迹点始终保持B个横轴单位，然后返还第①步；If the new stroke is located to the left of the dynamic separator, that is, the new track point is located in the current sub-input area, it is determined that the handwriting input has not ended yet, and the processing component of the touch screen input device continuously finds the rightmost right in the current sub-input area. Track points and keep the dynamic separators to the right, ensuring that the dynamic separator and the rightmost track point of the current sub-input area always maintain B horizontal axis units, and then return to step 1;
当前显示格、待显示格右移至显示行最右端时，自动转下一显示行；当前子输入区、动态分隔符或下一子输入区右移至当前输入区域最右侧时，自动转下一输入区域，其中M、N、A、B均为正整数，T为正数。T一般取0.3～2秒，M、N、A一般取8～10，B一般取4～6。When the current display grid and the to-be-displayed grid are moved right to the rightmost end of the display line, the next display line is automatically transferred; when the current sub-input area, dynamic separator, or next sub-input area is right-shifted to the far right of the current input area, the automatic rotation is automatically performed. The next input area, where M, N, A, and B are positive integers, and T is a positive number. T generally takes 0.3 to 2 seconds, M, N, and A generally take 8 to 10, and B generally takes 4 to 6.
如此设计，如果用户需要连续输入较长的字符串或单词，可以在当前子输入区内连续书写，这种情况下，当前子输入区可以不断随着用户的持续手写输入而自动伸展，满足用户需求。So designed, if the user needs to input a long string or word continuously, it can be continuously written in the current sub-input area. In this case, the current sub-input area can be automatically extended with the user's continuous handwriting input, satisfying the user. demand.
用户写完一个词组或单词后，只需移动很小距离，跨过动态分隔符，进入下一子输入区内书写，刚写完的词组或单词就可进入后台处理，十分方便。After the user finishes writing a phrase or word, he only needs to move a small distance, cross the dynamic separator, and enter the next sub-input area to write. The just-written phrase or word can be processed into the background, which is very convenient.
作为优化，所述动态分隔符呈竖线状。如此设计，分隔符结构简单，占用面积小。As an optimization, the dynamic separator is in a vertical line shape. So designed, the separator has a simple structure and a small footprint.
作为优化，当前显示行中也设有动态分隔符，当前显示格和待显示格右移时，动态分隔符随同右移，该动态分隔符始终位于当前显示格和待显示格之间。如此设计，该动态分隔符如同现有输入设备中的指示输入位置的鼠标。As an optimization, the current display line also has a dynamic separator. When the current display grid and the grid to be displayed are shifted to the right, the dynamic separator is shifted to the right, and the dynamic separator is always located between the current display grid and the grid to be displayed. So designed, this dynamic separator is like the mouse in the existing input device indicating the input position.
作为优化，第②步动态分隔符右移时，其原位上生产成一个静态分隔符，点击某一静态分隔符，可在该静态分隔符处插入手写输入，也可删除其左侧或右侧手写输入影像。如此设计，便于编辑。As an optimization, when the dynamic separator of step 2 is shifted to the right, it is produced as a static delimiter in situ. Click on a static delimiter to insert the handwritten input at the static separator, or delete the left or right side. Input the image by hand. Designed to be easy to edit.
本发明的核心在于：通过增设动态分隔符，在当前输入区域中分隔出 一个长度可以根据需要不断延长的当前子输入区域和一个可以不断右移的下一子输入区，当用户需要时，只需笔尖或指头跨过动态分隔符，进入下一子输入区书写，就可使刚刚书写完成的文字得到后台处理(暂存或者暂存和识别)。The core of the invention is to separate the current input area by adding a dynamic separator. A current sub-input area that can be extended as needed and a next sub-input area that can be continuously shifted to the right. When the user wants, only the nib or the finger crosses the dynamic delimiter and enters the next sub-input area to write. The text that has just been written can be spooled (temporary or temporary and recognized).
与现有技术相比，本发明的优点在于：The advantages of the present invention over the prior art are:
(1).步骤少、速度快、效率高；(1). Less steps, faster speed and higher efficiency;
(2).有助于提高字迹识别率；(2). Help to improve the handwriting recognition rate;
(3).便于后期编辑；(3). Easy for later editing;
(4).当前子输入区可以方便地根据需要延行，字符排布疏密控制方便，供用户后续书写时参考；(4). The current sub-input area can be conveniently extended according to needs, and the character arrangement is convenient and convenient for reference for the user to write later;
(5).本发明支持快速逐个字(或单词)输入，也可支持用户一次输入多个字符(或单词)。(5). The present invention supports fast word-by-word (or word) input, and also allows the user to input multiple characters (or words) at a time.
本发明适用于汉语、日语、韩语等方块文字输入，英语、法语、德语等字母文字的输入处理，以及各种标点符号的输入处理。适合个人电脑、智能手机、掌上电脑等各种支持外部输入的终端设备使用。The invention is suitable for inputting Chinese characters in Chinese, Japanese, Korean, etc., input processing of alphabetic characters such as English, French, German, and input processing of various punctuation marks.
