JP6924752B2 - Kanji and number input keyboard using the touch screen of the terminal and its input method - Google Patents

Description

The present invention relates to the input of Chinese characters in a portable terminal or the like, and more specifically, it is an input key that is arranged and input according to the Yin-Yang five-line principle, which is the principle of producing Chinese characters in a portable terminal. Therefore, while reducing the number of keys to fit small portable devices, the size is increased to ensure a smaller number of touches and shorter fingering distances, allowing users to enter kanji and numbers quickly and conveniently. The present invention relates to a keyboard for inputting kanji and numbers using the touch screen of the terminal and its input method.

In general, the method of inputting Chinese characters on mobile digital mobile devices such as keypad-type mobile phones and smartphones mainly employs the method of converting the pronunciation by typing phonetic characters.
To explain the above method in detail, mainly in China and Japan, the pronunciation of kanji is in the English alphabet (or romaji), in Taiwan it is a Bopomofo created based on the drawing of the kanji, and in South Korea it is struck in Hangul. After that, convert this to Kanji.
The pinyin (using the English alphabet) method, which is often used when entering Chinese texts on the keyboard of a computer or mobile phone in China, is not only slow because there are many characters in the same pronunciation, but also the self-characters. There is a big drawback that it cannot be used properly. In Japan, we use the method of converting after typing using our own characters, kana (kana) and the English alphabet, but in many cases the pronunciation of the kanji used is different. For example, the name "Suzuki" is pronounced in 14 types such as Suzuki, Suzuki, Suzuki, Susuheki, and Nuzuki. Therefore, it is not easy to find and input this by pronunciation. Furthermore, when using kana, if you try arranging 46 characters on the keyboard with few keys, the number of strokes will increase when you type, and you can also use the English alphabet, which is a Chinese pinyin. As such, it has the disadvantage of not being able to use its own characters.
In the case of portable keyboards in China, the most commonly used pinyin input method is to arrange multiple kanji with the same pronunciation by typing the pronunciation of the kanji using romaji, and one of the desired kanji. It is a method to select. However, this method cannot be used by anyone who does not know the pinyin, and even if it does, it is necessary to know the pinyin of all characters accurately. If you misspell the romaji, you will not be able to find the desired character. In addition, there are a plurality of kanji characters that correspond to one pronunciation. For example, in the case of zhong, there are as many as 17 kanji corresponding to this pronunciation. There is a problem that it is troublesome and slow because you have to search for the kanji you want from among the many characters.
In the case of China, there is a five-stroke keyboard that allows you to combine the radicals of Chinese characters and enter them as they are, but since multiple pictures and radicals are listed on one key, it is a lot to remember and master. It takes time and effort. But even this is not easy on most portable devices that have a limited keyboard size. A slide type keyboard may be manufactured separately for a mobile phone, but this has the drawback of increasing the size and weight of the phone.
When an input method using pinyin is adopted in a smartphone, there are roughly a 9-key method and a QWERTY arrangement method. The general 9-key method has the disadvantage that the number of strokes increases because 3 to 4 spells are arranged on one key, and when a QWERTY keyboard is inserted, the size of each key becomes smaller. There is a drawback that the rate of erroneous input is high.
Some of them have improved these drawbacks by using pinyin prediction and word prediction functions like Google Chinese input machine, but multiple pinyins and words are predicted or displayed on the screen with the entered keys. There is a drawback that it is necessary to always watch the screen because the predicted words to be made do not match 1: 1.
Many other portable pinyin inputs use a method that allows you to enter only the first consonant of the pronunciation of a frequently used word, but for less frequently used words. Since it is impossible in some cases, it limits fast and convenient input.
The use of conversion methods in all countries that use kanji without directly typing them comes from a lack of understanding of the principles by which kanji was created, which is ultimately the result of kanji. Was the decisive cause for the characters to remain as difficult-to-type characters.
In the Korean Registered Patent Gazette No. 1449375 by the applicant, 48 pictures are duplicated on 12 keys on the 3-year-old Ying-Yang five-line key based on the idea of Tenshokyo, and then the Kanji picture is used directly. However, the user may feel confused about the combination of images that make up the kanji, and the three three-year-old keys represented by the numbers 1, 2, and 3 are added to the keyboard, which makes it a small mobile phone. Not only does it occupy a lot of space in the equipment, but because the keyboard is large, there is a drawback that the fingering distance becomes long when inputting with only the thumbs of both hands.
As a prior art document related to this, Korean Patent Publication No. 2010-0135340 combines not only the touched position but also the direction and locus that moved after touching (Touch-and-Move), but it is fundamental. There seems to be a limit to increasing the input speed, and Korean Registered Patent Gazette No. 0662553 is a method that eliminates the use of radicals and combines 28 basic strokes. Is very inconvenient to enter.

An object of the present invention for improving the above-mentioned conventional problems is a touch of a terminal having excellent intuition that can be recognized at a glance while pursuing convenience in line with the kanji character making principle. It is an object of the present invention to provide a keyboard for inputting kanji and numbers using a screen and an input method thereof.
Another object of the present invention is to extract the most basic minimum images that compose Chinese characters, such as the English alphabet and Hangul consonants, and to use the images extracted in this way as the pictogram meaning of each image. Not only are they arranged to fit the keyboard, but the number of keys that make up the keyboard is reduced by utilizing the characteristics that appear in the interrelationships between the strokes that make up the kanji, and at the same time, each key is effective. Not only is it easy and convenient to enter complex kanji, even on small portable devices, but it is also easier to finally understand how the kanji was created. The purpose of the present invention is to provide a keyboard for inputting kanji and numbers using the touch screen of a terminal, and an input method thereof, which assists in learning kanji.

In order to achieve the above object, according to one aspect of the present invention, in a Chinese character input keyboard using a touch screen of a terminal: four internals centered on a central key 12 for input commands. Basic dots for inputting 22 Chinese characters are placed on 12 keys consisting of key 14 and 8 external keys 16, and numbers 0 to 12 are placed on each key including the center key. Main input unit 10 configured by arranging The selection unit 20; is included.
According to the detailed configuration of the present invention, 0 is arranged in the center key of the main input unit 10 and matched with the serial number shown in the number unit 21 of the selection unit 20 for selection of radicals and characters. The remaining keys are characterized by elastically arranging numbers from 1 to 12.
According to the detailed configuration of the present invention, four internal keys 14, the first row of the second column, and the outer keys of the third row of the second column have numbers 1, 2, and 3 for inputting numbers, respectively. It is characterized in that the numbers 4 to 9 are distributed and arranged on the remaining 6 foreign keys.

According to the detailed configuration of the present invention, the radical 23 of the selection unit 20 displays a radical including an image selected from the basic strokes of the internal key 14 and the foreign key 16, and the character unit 25 is a basic stroke or a basic stroke. It is characterized in that a character including a radical selected from the radical 23 is displayed.
According to another aspect of the present invention, in the method of inputting kanji on the touch screen of the terminal using the keyboard: When the basic dot drawing is input by the main input unit 10, the characters are immediately selected as the characters of the selection unit 20. When the first mode displayed on the unit 25 and the basic point drawing are input in the main input unit, the radical is displayed on the radical 23 of the selection unit 20, and the target radical is displayed from among these displayed radicals. When is selected, a word is obtained by combining the second mode in which the character including the radical is displayed in the character part 25 and the central key 12 and any one of the external key 16 or the internal key 14. And a fixed phrase are registered, and these registered words and fixed phrases are recalled, and a third mode is displayed in the selection section provided on the existing keyboard or another window, and is displayed in the selection section. In this state, the corresponding characters, words, or fixed phrases are input by the method instructed by the main input unit.
According to the detailed configuration of the present invention, when inputting the basic point strokes, the first arranged strokes on the keys individually or duplicated in the keys are input with one push of the keys and duplicated. The second arranged stroke on the arranged keys shall be input in combination with each key and one other key other than that key, utilizing the correlation between the strokes that make up the kanji. It is characterized by.
According to the detailed configuration of the present invention, in the first mode, as the most basic method of character input, images constituting Chinese characters are input in order by stroke order using the images on the main input unit 10. Then, the character including the image is displayed in the character unit 25 of the selection unit 20.
According to the detailed configuration of the present invention, the second mode includes the radical as soon as the selection is made from the series of radicals displayed on the radical 23 of the selection unit 20. If a character is displayed or there is no character you want to input, press the next image of the radical in order on the main input unit 10 again, and a series of characters including that radical will be displayed in the character part 25 of the selection unit. It is characterized by displaying.
According to the detailed configuration of the present invention, the third mode is not only for words and fixed phrases directly registered by the user, but also for preset words and fixed phrases, and frequently used words and fixed phrases by the user. It is characterized in that at least one of them is mounted in a memory and displayed on an existing keyboard or a selection unit separately provided in a new window.
Directly touch the letters, words, or fixed phrases that you want to enter in the state of being arranged in the selection section by the three methods described above, or use the numbers from 1 to 12 in the method instructed by the main input section. , The feature is that it is finally input.
According to the detailed configuration of the present invention, when selecting a character or a radical in the first mode and the second mode, the center key 12 serves as a character or radical selection key. do.
The numbers arranged on the existing keyboard are for inputting letters, but at the same time, considering the role of the numbers 1, 2 and 3 which means three years old in the process of five lines, all the numbers are internal. By rearranging it to an external key, it becomes a keyboard for inputting numerical values.
On the other hand, prior to this, the terms and words used in this specification and in the scope of patent claims should not be construed as limited to ordinary or lexical meanings, and the inventor best considers his own invention. In order to explain in the best way, it should be interpreted as a meaning and concept consistent with the technical idea of the present invention, based on the principle that the concept of terms can be properly defined. Therefore, the examples described herein and the configurations illustrated in the drawings are merely one of the most desirable embodiments of the present invention and do not represent all the technical ideas of the present invention. It must be understood that at the time of filing there may be various equivalents and variants that can replace them.

As described above, according to the present invention, the minimum basic strokes necessary for inputting all Chinese characters are extracted based on the principle of the five lines of Yin and Yang, which is the principle of making Chinese characters, and these basic strokes are used as the strokes. Since it is arranged in each key based on the contained idea, intuition and convenience are realized at the same time, and the user can use it easily and conveniently.
In addition, in the picture composition of all kanji, it is possible to efficiently input all pictures by the mutual organic combination of the keys in which these are arranged by utilizing the special interrelationship between each picture. By setting this, even on a keyboard composed of a small number of keys, it is possible to input kanji conveniently and quickly at a speed second only to that of a computer's QWERTY keyboard.
Also, unlike the general perception that kanji is complicated and difficult to learn, as shown on this keyboard, it means that everyone who uses it as a character uses the simplicity of the pictures that make up the kanji. You can easily get used to Kanji as an ideographic character and use it as a communication tool between members of the Earth Village.

The figure which shows the whole structure of the kanji input keyboard by this invention. The figure which shows the specific structure of the kanji input keyboard by this invention. The figure which shows the specific structure of the number input keyboard by this invention.

Hereinafter, examples of the present invention will be described in detail based on the attached drawings.
According to one aspect of the present invention, a Kanji input keyboard using a touch screen of a portable terminal is proposed. Terminals are intended for portable devices with relatively small input and display areas, but are not necessarily limited to, including future small keyboards for computer input and other devices such as kiosks. good. Every device is equipped with a microprocessor, memory, and input / output interface for input / output with a touch screen. Therefore, the keyboard of the present invention is displayed on the touch screen based on a predetermined algorithm in the memory, and at the same time, input (command) is also performed by the touch screen.
First, referring to FIG. 1, the Kanji keyboard of the terminal according to the present invention is divided into two areas, a main input unit 10 and a selection unit 20.
The main input unit 10 of the present invention is a number from 0 to 12 on the internal key 14 and the external key 16 centering on the central key 12 for input commands, according to the basic stroke of Chinese characters and the serial number of the selection unit. Is arranged and configured.
The selection unit 20 of the present invention arranges a radical unit 23 that outputs a radical on one side corresponding to the number unit 21 displayed by a serial number according to the number of radicals and characters to be arranged, and the other. It is configured by arranging a character unit 25 that outputs characters on the side.
As shown in the figure, the main input unit 10 of the present invention has a structure of 3 columns and 3 rows as a whole, but from 4 keys in 4 directions around the center key 12 in the 2nd column and 2 rows. The main keyboard is composed of the internal keys 14 and the eight external keys 16 that form a yin-yang relationship between the four pillars at each corner, centered on the five keys in the center. It is called the Ying-Yang Five Lines Key.
That is, the present invention includes a central key 12, an internal key 14, and a foreign key 16 as the Ying-Yang five-line key created by utilizing the Ying-Yang five-line idea, and is composed of a total of 13 keys. Four foreign keys 14 are arranged outside the center key 12, and eight foreign keys 16 are arranged outside the internal key 14.
According to the detailed configuration of the present invention, 0 is arranged in the center key of the main input unit 10, and numbers 1 to 12 representing the 12 zodiac signs in the five lines of Ying-Yang are used as the serial number of the selection unit 20 in the remaining keys. It is characterized by being elastically arranged together. Of course, such arrangement of numbers is one means for inputting characters, and may have various forms.

This makes it possible to express all Chinese characters with a total of 22 strokes, including 4 representative strokes that show the four elephants and 18 strokes that show the changes in the process of the Ying-Yang Five Lines. It is a basic point stroke that composes.
The interrelationship between the images arranged in each key and the reason why they are arranged in the key are as follows.
The four pillars at each corner of the foreign key 16 shown in FIG. 1 form a yin-yang relationship with each other in the vertical and horizontal directions, and such a relationship has a close relationship with the arrangement structure of the Kanji picture. There is. Among them, the hierarchical relationship is a perfect yin-yang relationship and consists of two left and right axes. Therefore, it can be seen that the main meaning of kanji is formed in this hierarchical relationship.
The images arranged in the first row, the first column and the third column on the drawing, and the images arranged in the third row, the first column and the third column are in a horizontal relationship with each other. On the other hand, the images arranged in the first row and the third row of the first column and the images arranged in the first row and the third row of the third column are in a vertical relationship with each other.

In this way, the reason why each picture is duplicated in one key for each other is not only useful for understanding kanji, but also the keys that are duplicated using the correlation between pictures. This is because when the second arranged image is input in, it is used as a kind of function key.

The images arranged in the character keys composed of 12 internal and external keys in this way are composed of 12 groups in total, 22 in total, and these are arranged based on the wisdom of the Ying-Yang Five Lines. Of these, the 20 most important ones are naturally arranged in the keys near the thumb when inputting, and the remaining two are arranged in the second column, the first row and the third row, which are far from each other.
As in the above picture arrangement, there are basically four four elephants at the center of the change in the universe generation, and communication between these four elephants creates new ones. There is an order in the communication process between them, and there is compatibility with each other in the relationship, so if you understand these order and compatibility, you can improve the utilization of each key.

The reason why such a phenomenon that the strokes cannot meet each other continuously occurs is that the Ying-Yang Five Elements idea is essential, and the stroke composition of the Chinese characters is made in a certain order. In other words, there is a process, and this process is exactly the same as that of the generation and change of all things, which makes it possible to understand the essential meaning of Chinese characters.
According to another aspect of the present invention, in the method of inputting a Kanji image on the touch screen of a portable terminal using the keyboard described above; the image arranged alone on one key and the two overlap. For the first arranged image of the arranged keys, you only have to press the corresponding key once, and for the second arranged image of the two overlapping keys, the stroke order is on between each of the above-mentioned images. , It is input in combination with other keys other than the corresponding key by utilizing the feature that cannot come continuously.
When inputting in combination with other keys, the condition that can be combined is that the first arranged images on the two keys to be combined appear in succession in the composition of all Kanji image as explained above. The point is that it should not come.

It can be seen that such a combination is intelligently possible without checking all the cases of many Kanji characters. The above example of the combination is only a typical combination in consideration of the fingering distance and the input using both hands, and can be combined with any key as long as it does not violate the above-mentioned rule.
As in the above example, if you combine two images in which the first arranged images of each key do not come continuously, you can input with a simple input algorithm, but the keys in which the images that come continuously come are arranged. When inputting in combination with, there is a drawback that the input algorithm becomes complicated, which may make input inconvenient from the user's point of view.

In this way, the main reason for inputting images that are duplicated in combination with other keys is small with only 13 keys on the main input unit 10 even if there is no other key for the combination. This is because it is possible to input many complicated kanji quickly and conveniently with a portable device.
When each image is input by the above method, up to 12 radicals and characters containing the image are listed in the radical 23 and the character 25, and one of them can be pressed directly or with the selection key. The number on the main input unit 10 corresponding to the serial number on the radical or character number unit 21 to be input by a certain central key 12, the radical 23 or the character unit 25 is continuously pressed, or the main input unit You can use all three methods of entering characters by pressing and holding for a certain period of time until the serial number corresponding to the character you want to enter is selected from the numbers 1 to 12 above.
The reason why you have to keep pressing for a certain period of time until a character is selected by the third method is that the numbers are overlapped with the image on the main input section, so it is differentiating in the input of the image and the selection of the character. Because you have to do it.
When selecting the radical or character, when the upper image close to the selection part 20 is input, it is convenient to directly press the radical or character of the selection part, and when inputting the lower image, the center key 12 and the main It is convenient to use the numbers on the input section or simply press and hold the numbers for a certain period of time until they are selected, as in the case of character selection. By selectively using the three methods in this way, input becomes easier and more convenient.
According to the detailed configuration of the present invention, the radical portion 23 of the selection portion 20 displays a radical portion including an image selected from the group of basic strokes of the internal key 14 and the external key 16, and the character portion 25 displays the radical portion. It is characterized in that the basic point strokes arranged on each key and the characters including the radical selected from the radical 23 are displayed.
The 22 pictures described in the present invention are arranged based on the reason of the Ying-Yang Five Lines in consideration of their importance, convenience of input, and intuition, thereby making it faster and easier. The head portion 23 and the character portion 25 are placed on the selection portion 20 so that the kanji input can be performed.
Up to 12 radicals can be arranged on the radical 23 according to the size of the portable device of the radical directly or indirectly related to the image arranged on each key. By selecting, it is possible to input complicated Chinese characters more easily and quickly. At this time, the radicals that are often used can be selected after pressing the first stroke that composes the radical, and the radicals that are not can be found by combining the second or third strokes. be able to. On the other hand, for images with many radicals, it is possible to search for radicals in any combination of images for high-speed input.
Further, it is also possible to continuously arrange different radicals including the corresponding image by continuously pressing the center key 12 which is a character selection key while being a radical selection key together with the above method. As a result, in the case of the radical 23, which can arrange up to 12 radicals, a total of 36 radicals can be arranged with three center key touches, so that quick selection of radicals is possible. be.
According to the detailed configuration of the invention, the central key 12, which is a radical selection key but also serves as a character selection key, serves as a radical selection key if the radical 23 has a radical to be selected. If there is no radical to select, it acts as a character selection key. At this time, as a character selection key, after hitting the center key, you can systematically press a number on the main keyboard to select a character, so you do not have to press it for a certain period of time, and high-speed input may be possible depending on the situation. It is possible.
When selecting a radical or a character, if the center key 12 is pressed continuously for the time being, other radicals and characters containing the same image are sequentially arranged. That is, if the center key 12 is hit once to select a radical and then hit continuously, many radicals including the image can be listed in order. To select letters in the same way, hitting the middle key and then hitting it will allow you to sequence many letters, including already hit pictures and radicals. Whether to enter the desired kanji while typing the images that make up the kanji you want to enter, or to enter the desired kanji by hitting the center key continuously, depends on the kanji you want to enter. Can be done.
The number of radicals and characters arranged in the radical portion 23 and the character portion 25 on the selection unit is determined according to the size of the portable device. For example, 8 pieces can be arranged for a small device, 10 pieces can be arranged for a medium size device, and a maximum of 12 pieces can be arranged for a large device.
According to another aspect of the present invention, there is proposed a method of inputting Chinese characters on the touch screen of a terminal using the keyboard.
When a basic stroke is input in the main input unit, characters are immediately displayed in the character unit 25 of the selection unit 20. When a basic stroke is input in the main input unit, characters are immediately displayed in the radical portion 23 of the selection unit 20. The second mode in which the radicals are displayed, and after selecting the desired radical from these displayed radicals, the characters including the radicals are displayed in the character part, and the center key 12 and the inside By combining keys that do not overlap with other functions on the external key, words and phrases are registered and recalled and displayed in the selection section 20 on the keyboard or in the selection section provided in another new window. A third mode, which is displayed on the selection unit, is displayed on the selection unit, and a character, a word, or a fixed form can be used by pressing a number in a manner commanded by the main input unit or by directly selecting on the selection unit. It is characterized in that each clause is input.
When a picture is input, the characters in the completed form are listed in the character section 25, and the related characters containing the picture are listed while pressing the key corresponding to the picture. You will naturally understand what it is like. And if you know only the pictogram meanings of the 22 basic dot strokes arranged on this keyboard, you can naturally understand what the characters mean while striking the images that make up each character. It can be understood, and as a result, it becomes much easier to understand kanji.
In addition to entering kanji as described above, if you do not know any kanji, you can press one of the kanji arranged in the character window with your finger for a certain period of time to get information about the corresponding kanji in the online kanji dictionary. It is characterized by being displayed.
According to the detailed configuration of the present invention, in the second mode, after the selection is made from the series of radicals shown in the radical 23 of the selection unit 20, the characters including the radical are immediately displayed. If the target characters are not immediately arranged in the character section 25, press the next image of the radical on the main input section 10 in sequence, and a series of characters including the corresponding radical will be displayed. It is characterized in that it is displayed on the character unit 25 of the selection unit 20.
The method of selecting the radical is to directly press the radical of the radical 23 or to combine the center key 12 using the selection key with the number on the main input unit 10. By selecting and inputting radicals in this way, fast input becomes possible.
Since this keyboard is generally limited in the size of portable devices, there is no display for displaying the struck image in order to reduce the space occupied by the keyboard. Of course, it can be indirectly recognized through the characters that change each time the stroke is hit, but since it is not perfect, the selection section is selected each time one stroke is hit so that the user can recognize how many strokes have been hit. By changing the color of the number in the number part 21 on 20, the user can know the number of strokes currently shot. Of course, a large device can be equipped with a separate display that displays the shot image.
Further, in a portable device having a small size, in the basic keyboard configuration, only the character part 25 is expanded to the selection part 20 in the upper part of the keyboard, and when the radical selection key is pressed, the character part becomes the radical part at that time. If you select the radical, you can change it to the character part again.

At this time, if the characters "ground" are not arranged immediately after pressing the radical selection key, the next image of the radical can be input while being pressed in order. If the number of characters including the radical is not large, you can arrange the characters including the radical in order while pressing the center key 12 as the character selection key in succession, so select these two methods. Can be used as a target.
If you cannot enter a certain character at high speed in the first mode or the second mode, you can use the word / fixed phrase input function of this keyboard, which is the third mode, for quick input. Is. The method of inputting must be decided by the user through the input experience.
According to the detailed configuration of the present invention, the third mode is not only for words and fixed phrases directly registered by the user, but also for preset words and fixed phrases, and frequently used words and fixed phrases by the user. A series of words or phrases displayed in the selection section 20 of this keyboard or the selection section provided in another window, in which at least one of them is installed in the memory and performed in the first mode or the second mode. Of these, the input is made by directly pressing the target word or fixed phrase, or by pressing the number according to the method instructed from the main input unit 10.
When you perform a large amount of input work on a certain theme, you will frequently enter words and fixed phrases related to that theme, and at this time, if you register frequently used words and fixed phrases in advance. , Can be entered easily and quickly. The preset words and phrases in the third mode mean that the application provider has entered them into memory. You can also enter words and phrases that you want in memory. More advanced apps (apps) can also analyze user input and store frequently used words or phrases in memory.

In the future, the keyboard for inputting kanji of the present invention will take advantage of kanji, which is the only ideographic character on the earth, and will allow people in other languages to use characters without having to study a foreign language separately. Since they can basically communicate with each other, they will play a central role in creating an environment in which future global villagers can easily communicate with each other.
The present invention is not limited to the described examples, and it is a person having ordinary knowledge in the field of this art that various modifications and modifications can be made without departing from the idea and scope of the present invention. It is self-evident to. Therefore, such modifications or modifications should be said to belong to the claims of the present invention.
