本发明涉及中文信息处理和人机交互技术领域，具体地说是一种用于输入汉字的虚拟键盘及操作方法。The invention relates to the technical field of Chinese information processing and human-computer interaction, in particular to a virtual keyboard for inputting Chinese characters and an operation method.
背景技术Background technique
目前，大多数汉字编码输入法都是对汉字的字形或读音等特征进行编码并映射为标准键盘上按键的组合。可以使用各种各样的汉字输入法将汉字输入计算机，不同的输入法将汉字编码为不同的键盘按键组合，敲击相应的键盘按键组合，即可将对应的汉字输入计算机。也有方法在计算机显示屏幕上虚拟出键盘区域，使用鼠标或电子笔等定点输入设备操纵光标在虚拟键盘上进行类似的操作以输入汉字。使用标准键盘的汉字输入方法主要适合带有标准键盘输入设备的计算机，而掌上电脑等没有标准键盘输入设备的计算机则不能够使用此方法输入汉字。对于掌上电脑等小屏幕计算机，在屏幕上显示标准输入键盘的虚拟键盘的方法占用了太多的屏幕空间，而且操作起来很不方便。另外一种方法是使用笔完整的书写整个汉字，然后由计算机进行模式识别，识别出所书写的汉字并输入计算机。这种方法的主要问题在于需要完整地书写整个汉字，比较费时。At present, most Chinese character encoding input methods are to encode features such as the font or pronunciation of Chinese characters and map them to combinations of keys on a standard keyboard. Various Chinese character input methods can be used to input Chinese characters into the computer. Different input methods encode Chinese characters into different keyboard key combinations, and the corresponding Chinese characters can be input into the computer by tapping the corresponding keyboard key combinations. There is also a method to virtualize the keyboard area on the display screen of the computer, and use fixed-point input devices such as mouse or electronic pen to manipulate the cursor to perform similar operations on the virtual keyboard to input Chinese characters. The Chinese character input method that uses standard keyboard is mainly suitable for the computer that has standard keyboard input equipment, and the computer that does not have standard keyboard input equipment such as palmtop computer then can not use this method input Chinese character. For small-screen computers such as handheld computers, the method of displaying the virtual keyboard of the standard input keyboard on the screen takes up too much screen space, and is very inconvenient to operate. Another method is to use a pen to completely write the entire Chinese character, and then the computer performs pattern recognition to recognize the written Chinese character and input it into the computer. The main problem of this method is that the entire Chinese character needs to be written completely, which is time-consuming.
发明内容Contents of the invention
本发明的目的是提供一种用于输入汉字的虚拟键盘及操作方法，该方法简单易用，适合于多种汉字编码方法，尤其适合于使用触笔直接在掌上电脑的显示屏幕上进行汉字输入。The purpose of the present invention is to provide a virtual keyboard and operation method for inputting Chinese characters, which is simple and easy to use, and is suitable for a variety of Chinese character encoding methods, especially suitable for using a stylus to directly input Chinese characters on the display screen of a handheld computer .
本发明是这样实现的：用于输入汉字的虚拟键盘是指在计算机显示屏幕上的一块区域，区域中包含若干小的区域，每个小区域代表特定的字符、符号或具有特定含义。操作者使用定点输入设备移动光标至特定区域并按下定点输入设备的按钮(如果定位设备是电子笔或掌上电脑的触笔则是按下笔)，随后放开按钮(如果定位设备是电子笔或掌上电脑的触笔则是抬起笔)，此操作一般称为点击，点击特定区域表示输入此区域所代表的字符或符号，或者执行特定含义的操作。The present invention is realized in this way: the virtual keyboard for inputting Chinese characters refers to an area on the computer display screen, the area includes several small areas, and each small area represents a specific character, symbol or has a specific meaning. The operator uses the pointing input device to move the cursor to a specific area and presses the button of the pointing input device (pressing the pen if the pointing device is an electronic pen or a stylus for a handheld computer), and then releases the button (if the pointing device is an electronic pen or The stylus of the handheld computer is to lift the pen), this operation is generally called clicking, clicking on a specific area means inputting the character or symbol represented by this area, or performing an operation with a specific meaning.
本发明使用的虚拟键盘使用“横”、“竖”、“撇”、“捺”、“折”、“复折”六个笔画虚拟键盘按钮以及四行六列的汉语拼音首字母虚拟键盘按钮来输入汉字。通过定义对这六个笔画虚拟键盘按钮的三种基本操作方法：点选操作、线选操作和复选操作，实现将汉字中的基本笔画间的关系信息输入计算机，最终达到输入汉字的目的。The virtual keyboard used in the present invention uses six stroke virtual keyboard buttons of "horizontal", "vertical", "left", "right", "fold", and "fold" and four rows and six columns of Chinese phonetic initials virtual keyboard buttons to enter Chinese characters. By defining three basic operation methods for these six stroke virtual keyboard buttons: click operation, line selection operation and multiple selection operation, the relationship information between the basic strokes in Chinese characters can be input into the computer, and finally the purpose of inputting Chinese characters can be achieved.
虚拟键盘由笔画输入部分和汉语拼音首字母输入部分组成，笔画输入部分如图1所示，汉语拼音首字母输入部分如图2所示。笔画输入部分由六个同等大小的相邻笔画区域构成，各区域呈中心对称分布，分别对应六种基本笔画：横、竖、撇、捺、折、复折，每个笔画区域代表一种基本笔画，笔画输入中心部分为空白区域。汉语拼音首字母输入部分由四行六列的方形输入区域构成，每个方形区域代表一个汉语拼音首字字母，第一列的各行代表的字母分别为：b、p、m、f，第二列的各行代表的字母分别为：d、t、n、l，第三列的各行代表的字母分别为：g、k、h、y，第四列的各行代表的字母分别为：j、q、x、w，第五列的各行代表的字母分别为：z、c、s、r，第六列的各行代表的字母分别为：a、o、e、*，*为通配符，可以代表任意一个汉语拼音首字字母。The virtual keyboard is composed of a stroke input part and a Chinese pinyin initial letter input part. The stroke input part is shown in FIG. 1 , and the Chinese pinyin initial letter input part is shown in FIG. 2 . The stroke input part is composed of six adjacent stroke areas of the same size. Each area is symmetrically distributed in the center, corresponding to six basic strokes: horizontal, vertical, left, right, folded, and compound folded. Each stroke area represents a basic stroke. Stroke, stroke input center part is a blank area. The first letter input part of Chinese Pinyin is composed of a square input area with four rows and six columns. Each square area represents a first letter of Chinese Pinyin. The letters represented by each row in the first column are: b, p, m, f, and The letters represented by each row of the column are: d, t, n, l, the letters represented by each row of the third column are: g, k, h, y, and the letters represented by each row of the fourth column are: j, q , x, w, the letters represented by each line in the fifth column are: z, c, s, r, and the letters represented by each line in the sixth column are: a, o, e, *, * is a wildcard and can represent any A Chinese Pinyin initial letter.
笔画输入部分的操作使用定位输入设备完成，例如：鼠标、电子笔、光笔、掌上电脑的触笔等。对笔画输入部分的操作方法有三种，分别为：点选、线选和复选。每个操作过程从定位设备按钮按下、或是笔尖按下时开始，直到按钮放开或是笔尖抬起时单个操作完成。操作过程中，被选中的区域将被反白显示，以提示操作者，操作完成后所有区域恢复初始状态。如果操作过程中区域被两次反白显示，该区域仍然被选中。The operation of the stroke input part is completed using a positioning input device, such as a mouse, an electronic pen, a light pen, a stylus of a handheld computer, and the like. There are three operation methods for the stroke input part, which are: click, line and multiple selection. Each operation process begins when the pointing device button is pressed, or the pen tip is pressed, and is completed by a single operation when the button is released or the pen tip is lifted. During the operation, the selected area will be highlighted to remind the operator, and all areas will return to the original state after the operation is completed. If an area is highlighted twice during the operation, the area is still selected.
点选操作是指点击单个笔画区域内部任意一点即选中该区域，当区域被选中时，区域将被反白显示，以提示操作人员，随后区域恢复正常显示，以接受下一次操作。按顺序连续进行两次点选操作，选中的两个笔画区域对应的基本笔画按顺序构成一般关系，连续的两次点选操作表示操作选中的这两个基本笔画间构成一般关系。连续进行的两次点选可以选择不同区域，也可以选择同一个区域。图5中，使用一个实心圆点表示点击位置，操作的结果是选择点击所在区域。Clicking operation refers to clicking any point inside a single stroke area to select the area. When the area is selected, the area will be highlighted to remind the operator, and then the area will return to normal display to accept the next operation. If two consecutive clicking operations are performed in sequence, the basic strokes corresponding to the two selected stroke areas form a general relationship in order, and two consecutive clicking operations indicate that the two basic strokes selected by the operation form a general relationship. Two consecutive clicks can select different areas or the same area. In Figure 5, a solid circle is used to indicate the click position, and the result of the operation is to select the clicked area.
线选操作是指进行划线操作，使得线的起点和终点分别落在两个不同的笔画区域内部，并且线不经过此外的其它笔画区域；在划线过程中，当线的末端进入相应的笔画区域时，区域将被反白显示，划线完毕后，反白显示的区域恢复正常显示，以接受下一次操作；线选操作选中起点所在区域和终点所在区域对应的两个基本笔画，该操作表示这两个基本笔画按顺序构成交叉关系。图3中，实心圆点代表起点，实心箭头代表终点，起点与终点之间的粗实线代表所画的线。The line selection operation refers to the line-drawing operation, so that the starting point and end point of the line fall within two different stroke areas, and the line does not pass through other stroke areas; When the stroke area is drawn, the area will be highlighted. After the line is drawn, the highlighted area will return to normal display to accept the next operation; the line selection operation selects the two basic strokes corresponding to the area where the start point is located and the area where the end point is located. The operation indicates that these two basic strokes form a cross relationship in sequence. In FIG. 3 , the solid circle represents the start point, the solid arrow represents the end point, and the thick solid line between the start point and the end point represents the drawn line.
复选操作是指进行划线操作，使得线的起点和终点落在同一个笔画区域，并且线还要经过且仅经过另外一个笔画区域，操作选中起点所在区域和线经过区域对应的基本笔画，该操作表示这两个基本笔画按顺序构成方框关系。图4中，实心圆点代表起点，实心箭头代表终点，起点与终点之间的粗实线代表所画的线。The multi-selection operation refers to the line-drawing operation, so that the starting point and the ending point of the line fall in the same stroke area, and the line will pass through and only pass through another stroke area. The operation selects the basic strokes corresponding to the area where the starting point is located and the area where the line passes. This operation indicates that the two basic strokes form a frame relationship in sequence. In FIG. 4 , the solid circle represents the starting point, the solid arrow represents the end point, and the thick solid line between the starting point and the end point represents the drawn line.
汉语拼音首字母输入部分的操作使用定位输入设备在字母区域内进行点击操作来选择相应的字母，这是公知的操作方法。The operation of the Chinese Pinyin initial letter input part uses a positioning input device to click in the letter area to select the corresponding letter, which is a known operation method.
使用上述三种操作对虚拟键盘进行操作，可以得到由六种基本笔画中任意两个笔画构成的三种笔画间的关系：交叉关系、方框关系和一般关系，其中线选操作确定交叉关系，复选操作确定方框关系，连续两次点选操作确定一般关系。这三种关系用于表达汉字以及形成汉字的部件中基本笔画间的关系。这些关系是以字形为基础进行汉字编码的要素。Use the above three operations to operate the virtual keyboard, and you can get the relationship between the three strokes composed of any two strokes in the six basic strokes: cross relationship, box relationship and general relationship, in which the line selection operation determines the cross relationship, The double-selection operation determines the box relationship, and the double-click operation determines the general relationship. These three relationships are used to express the relationship between basic strokes in Chinese characters and the components that form Chinese characters. These relations are the elements of encoding Chinese characters on the basis of fonts.
本发明中的虚拟键盘以及操作方法提供了将汉字基本笔画间的关系信息以及汉语拼音首字母等信息输入计算机的方法和手段(这些信息输入计算机以后如何转换为对应的汉字的方法并非本发明的内容，本发明仅涉及虚拟键盘及操作方法，并不涉及对汉字进行编码的方法)。Virtual keyboard among the present invention and operation method have provided the method and the means of information input computer such as the relational information between the basic strokes of Chinese character and Chinese phonetic alphabet initial letter (the method how these information input computer is converted into corresponding Chinese character is not the present invention Content, the present invention only relates to the virtual keyboard and the operation method, and does not relate to the method for encoding Chinese characters).
与现有技术相比，本发明更加适合在掌上电脑等小屏幕计算机上使用触笔输入汉字，而且无需书写整个汉字，具有使用简单，记忆量小等优点。Compared with the prior art, the present invention is more suitable for inputting Chinese characters with a stylus on computers with small screens such as palmtop computers, and does not need to write entire Chinese characters, and has the advantages of simple use and small memory capacity.

所述的线选操作是指进行划线操作，使得线的起点和终点分别落在两个不同的笔画区域内部，并且线不经过此外的其它笔画区域，在划线过程中，当线的末端进入相应的笔画区域时，区域将被反白显示，划线完毕后，反白显示的区域恢复正常显示，以接受下一次操作。The line selection operation refers to the line-drawing operation, so that the starting point and the end point of the line fall within two different stroke areas respectively, and the line does not pass through other other stroke areas. When entering the corresponding stroke area, the area will be displayed in reverse, after the stroke is completed, the area displayed in reverse will return to normal display to accept the next operation.
所述的复选操作是指进行划线操作，使得线的起点和终点落在同一个笔画区域，并且线还要经过且仅经过另外一个笔画区域。The multiple selection operation refers to performing a line-drawing operation, so that the starting point and the end point of the line fall in the same stroke area, and the line also passes through and only passes through another stroke area.
在具体实施中如果要使用本发明来输入汉字，还需要使用公知的汉字编码输入法对汉字进行编码。一个可选的公知汉字编码输入法是公开号为CN101038517A、申请号为200710065819.6的发明专利：一种汉字形声编码输入法。以汉字“本”为例，汉字的输入过程如下：In concrete implementation, if will use the present invention to input Chinese character, also need to use known Chinese character encoding input method to encode Chinese character. An optional known Chinese character encoding input method is the invention patent with publication number CN101038517A and application number 200710065819.6: a Chinese character phonetic encoding input method. Taking the Chinese character "本" as an example, the input process of Chinese characters is as follows:
1.使用线选操作“横”、“竖”笔画区域，即在笔画输入区域划线，使得线的起点落在“横”笔画区域，线的终点落在“竖”笔画区域，并且线不经过其它笔画区域。此操作确定“本”字的第一笔画“横”、第二笔画“竖”构成交叉关系。1. Use the line selection to operate the "horizontal" and "vertical" stroke areas, that is, draw a line in the stroke input area, so that the starting point of the line falls in the "horizontal" stroke area, and the end point of the line falls in the "vertical" stroke area, and the line does not through other stroke areas. This operation determines that the first stroke "horizontal" and the second stroke "vertical" of the word "Ben" form a cross relationship.
2.使用点选操作“撇”、“捺”笔画区域，此操作确定“本”字的第三笔画“撇”和第四笔画“捺”构成一般关系。2. Use the click to operate the stroke areas of "把" and "捷". This operation determines that the third stroke "数" and the fourth stroke "捷" of the word "本" constitute a general relationship.
3.使用点选操作“横”、“横”笔画区域，此操作确定“本”字的第五笔画“横”和末笔画“横”构成一般关系。3. Use the click operation "horizontal" and "horizontal" stroke areas. This operation determines that the fifth stroke "horizontal" and the last stroke "horizontal" of the character "Ben" constitute a general relationship.
4.点击汉语拼音首字母输入部分的“b”输入区域，确定“本”字的汉语拼音首字母为“b”。4. Click the "b" input area in the input part of the first letter of the Chinese pinyin, and confirm that the first letter of the Chinese pinyin of the word "Ben" is "b".
以上四步确定了专利200710065819.6中以“aydb”为编码的所有汉字。在以上各步骤中，符合条件的汉字将在汉字候选区中显示出来，有时并不需要完成所有步骤即可在候选区中找到所需输入的汉字。如果候选区中只有一个汉字，此汉字即为需要输入的汉字；如果候选区中有多个汉字，被选中的汉字即为需要输入的汉字。The above four steps determined all Chinese characters coded with "aydb" in the patent 200710065819.6. In the above steps, the qualified Chinese characters will be displayed in the Chinese character candidate area, and sometimes it is not necessary to complete all the steps to find the desired input Chinese character in the candidate area. If there is only one Chinese character in the candidate area, this Chinese character is the Chinese character to be input; if there are multiple Chinese characters in the candidate area, the selected Chinese character is the Chinese character to be input.
本技术领域的专业人员很容易根据上述说明以及公知的知识实现本发明的虚拟键盘，以及对虚拟键盘的操作。Those skilled in the art can easily implement the virtual keyboard of the present invention and operate the virtual keyboard according to the above description and known knowledge.
本发明经使用表明，完全达到设计要求。The use of the present invention shows that it fully meets the design requirements.
