Description

Hangul input device and Hangul input method using touch screen {HANGUL INPUT APPARATUS AND HANGUL INPUT METHOD USING TOUCH SCREEN}

The present invention relates to a Hangul input device and a Hangul input method, and more particularly to a Hangul input device and a Hangul input method using a touch screen for the input of Hangul.

Character input methods in a mobile terminal using a touch screen largely include a soft keyboard input method and a handwriting recognition method.

Among them, the soft keyboard input method refers to a method of receiving an input by a pen click by opening a keyboard-type input window on the touch screen to overcome the portability problem of a general keyboard and a mouse.

On the other hand, examples of a terminal with a touch screen include a navigation terminal, an electronic notebook, a mobile phone, a PDA, etc. In recent years, such terminals are becoming smaller and lighter, and thus, the size of the touch screen is also smaller and lighter. have.

Conventionally, a technique of displaying all 26 keys on a touch screen has been used to input an alphabet on the miniaturized touch screen. However, according to this conventional technology, the screen area for text input is inevitably increased, and as a result, the area for displaying the output text is relatively reduced.

In addition, in the case of a user who is not familiar with the alphabet, it is inconvenient because the user must input the key while searching for the key. In addition, since the user must press a small button of the keyboard displayed on the touch screen, as described above, there is an inconvenience of frequently pressing the wrong button by mistake.

On the other hand, a handwriting input method in a portable terminal using a touch screen is a method of recognizing human handwriting (ie, handwriting) and converting it into a data code.

However, such a handwriting input method is not only slow input speed because the user has to write a letter as a handwriting, there was an inconvenience that requires a lot of movement of the user. In addition, there is a problem that frequently input errors that are recognized as similar characters if the character that you want to input is not accurately described.

1 is a view for explaining an example of the Hangul input device according to the prior art.

Referring to FIG. 1, the conventional Hangul input device 100 includes sixteen keys 111 to 126 arranged in four rows and four columns.

The 16 keys (111-126) of the '1' key to the 'd' key include ('B', 'B', 'c', 'ㅏ', 'ㄹ', 'ㅁ', 'ㅂ', 'ㅓ' ',' ㅅ ',' ㅇ ',' ㅗ ',' TT ',' ㅈ ',' ㅎ ',' ㅡ ',' ㅣ ') are designated as primary keys, and the primary key is entered twice in succession. ('ㅋ', 'ㅌ', 'ㅑ', 'ㅑ', 'ㅕ', 'ㅛ', 'ㅠ', 'ㅊ'), and the primary key is entered three times in succession. ('ㄲ', 'ㄸ', 'ㅆ', 'ㅉ').

In other words, pressing the '1' key 111 two times in succession converts to 'ㅋ', and pressing the '1' key 111 three times in succession converts it to 'ㄲ'.

Also, pressing the '*' key 123 twice in succession converts it to 'ㅊ', and pressing it three times in succession converts it to 'ㅉ'.

However, according to the prior art as described above, the input of the twin consonants 'ㄲ', 'ㄸ', 'ㅃ', 'ㅉ' is the '1' key 111 and the '3' key in which the respective consonants are overlapped. There is an inconvenience that a relatively large number of touches are required because the input is performed by three consecutive presses of the 113, 6, 117, and 123 keys.

In addition, the related art has a problem in that a method of arranging consonants and vowels arranged in 16 key buttons arranged in four rows and four columns is inconvenient for the user to intuitively recognize. That is, two rows and four columns at the top of the four rows and four columns place consonants in three key buttons from the left and a vowel in the other one key buttons, but two rows and four columns at the bottom are two key buttons from the left. Since the consonants are arranged in the vowels on the remaining two key buttons, the arrangement of the consonant input unit and the vowel input unit is irregular and it is very inconvenient for the user to recognize them.

Meanwhile, as a prior art, Korean Laid-Open Patent Publication No. 2006-0100660 discloses an 'Epi Hangul input system' that can input Hangul using 14 Hangul consonants, 3 Hangul vowels, and double consonant keys. That is, the prior art, 14 Hangul consonants ('ㄱ', 'ㄴ', 'ㄷ', 'ㄹ', 'ㅁ', 'ㅂ', 'ㅅ', 'ㅇ', 'ㅈ', 'ㅊ') , 'ㅋ', 'ㅌ', 'ㄷ', 'ㅎ'), 8 Hangul vowels ('ㅏ', 'ㅓ', 'ㅗ', 'TT', 'ㅡ', 'ㅣ', 'ㅐ' , 'ㅔ') and the two consonants 'ㄱ', 'ㄸ', 'ㅃ', 'ㅆ', 'ㅉ' for the Korean consonants 'ㄱ', 'ㄷ', 'ㅂ', 'ㅅ', 'ㅈ' Enter Hangul using the consonant conversion key for conversion to '. For example, when the 'a' key and the double consonant conversion key is sequentially pressed, it is converted into 'ㄲ', and the 'c' is placed by the key and the double consonant conversion key is sequentially converted to 'ㄸ', When the key with the letter 'ㅂ' and the consonant conversion key are sequentially pressed, it is converted into 'ㅃ'.

However, the prior art discloses a technique of using a separate consonant key for inputting a consonant 'ㄲ', 'ㄸ', 'ㅃ', and 'ㅉ'. Since it is difficult to intuitively recognize the function of the consonant key, there is a problem that it is difficult to easily learn the Hangul input method without a separate manual.

According to an embodiment of the present invention, when a touch of one of the keys arranged with the Hangul consonants 'ㄱ', 'ㄷ', 'ㅂ', 'ㅅ', and 'ㅈ' is detected, input of a consonant corresponding to the touched Hangul consonants In order to visually guide the present invention, the present invention provides a Hangul input device and a Hangul input method using a touch screen that converts and displays a display of a twin consonant input key into a corresponding twin consonant.

As a technical means for achieving the above technical problem, the first aspect of the present invention is a Hangul input device using a touch screen, 'a', 'b', 'c' to four keys arranged in one row and four columns , The first consonant input unit for arranging and displaying the basic consonants of 'ㄹ', and the basic consonants of 'ㅁ', 'ㅂ', and 'ㅅ' on three keys arranged in one row and three columns below the first consonant input unit. A second consonant input unit for arranging and displaying the respective basic consonants of 'ㅇ', 'ㅈ', and 'ㅎ' on three keys arranged in one row and three columns below the second consonant input unit; 3 consonant inputs, 6 keys arranged in a row of 3 rows and 2 columns on the right side of the first and third consonant inputs, the basic of 'ㅏ', 'ㅓ', 'ㅗ', 'TT', 'ㅡ', 'ㅣ' A vowel input unit for arranging and displaying a single vowel, and 'b', 'ㄷ', 'ㅂ', 'ㅅ', 'ㅈ' includes a twin consonant input unit for converting and inputting a consonant of 'ㄲ', 'ㄸ', 'ㅃ', 'ㅆ', 'ㅉ', the basic consonant 'ㄱ', When a touch of one of the keys arranged with 'ㄷ', 'ㅂ', 'ㅅ', and 'ㅈ' is detected, the consonant corresponding to the basic consonant corresponding to the touched consonant is displayed on the display of the dual consonant input unit displayed on the touch screen. It provides a Hangul input device using a touch screen to switch to.

As a technical means for achieving the above-described technical problem, the second aspect of the present invention, in the Hangul input method using a touch screen, basic consonants 'ㄱ', 'ㄴ', 'ㄷ', 'ㄹ', 'ㅁ' , 'ㅂ', 'ㅅ', 'ㅇ', 'ㅈ', and 'ㅎ' to be displayed on the 10 keys on the touch screen, and displaying the same, among the basic consonants 'ㄱ', 'ㄷ', 'ㅂ' , 'Z', 'ㅈ' to 'twin', 'ㄸ', 'ㅃ', 'ㅆ', 'ㅉ' by placing a consonant input key to one key on the touch screen If a touch of one of the keys and the key consonants 'ㄱ', 'ㄷ', 'ㅂ', 'ㅅ', 'ㅈ' are arranged is detected, the input of the consonant input Using a touch screen including converting a display into a double consonant corresponding to the touched basic consonant Provides a way to enter text.

According to one of the above-described problem solving means of the present invention, by providing a separate consonant input key to reduce the number of touches of the key required to input the twin consonant, as well as the Hangul consonants' ㄱ ',' ㄷ ',' ㅂ When a touch of one of the keys arranged with ',' ㅅ 'and' ㅈ 'is detected, the display of the twin consonant input key is switched to a twin consonant corresponding to the touched Hangul consonant and displayed. You can enter

First, in step S11, 16 keys are displayed, and then the flow advances to step S12, in which the basic consonants and the coarse consonants are arranged and displayed on the 10 keys. That is, the basic consonants 'ㄱ', 'ㄴ', 'ㄷ', 'ㄹ', 'ㅁ', 'ㅂ', 'ㅅ', 'ㅇ', 'ㅈ' and 'ㅎ' And then place the consonant sounds of 'ㅋ', 'ㅌ', 'ㄷ' and 'ㅊ' in the 'AB', 'ㄷ', 'ㅂ', and 'ㅈ'. . In this case, the input of the consonant sounds 'ㅑ', 'ㅕ', 'ㅛ', and 'ㅠ' arranged in two layers may be performed by two consecutive touches of each key.

In step S13, the basic short vowels and the basic double vowels are arranged and displayed on the six keys. That is, the basic short vowels 'ㅏ', 'ㅓ', 'ㅗ', 'TT', 'ㅡ', 'ㅣ' are placed and displayed on each of the six keys, and then 'ㅏ', 'ㅓ', '복', 'TT' and '기본', 'ㅕ', 'ㅛ', 'ㅠ' basic double vowels are placed in duplicate. At this time, the input of the basic double vowels 'ㅑ', 'ㅕ', 'ㅛ', and 'ㅠ' arranged in two layers may be performed by two consecutive touches of each key.

In step S14, 'a', 'c', 'ㅂ', 'ㅅ', 'ㅈ' among the basic consonants are assigned to one key, 'ㄲ', 'ㄸ', 'ㅃ', 'ㅉ', 'ㅉ' The consonant input key for converting to a consonant of 'is arranged and displayed.

Those skilled in the art will readily appreciate that the steps S11, S12, S13 and S14 described above may be performed in any order or simultaneously.

In step S15, it is determined whether a touch of one of the keys including the basic consonants 'ㄱ', 'ㄷ', 'ㅂ', 'ㅅ', and 'ㅈ' is detected, and thus the basic consonants 'ㄱ' and 'c' If one of the keys, 'ㅂ', 'ㅅ', and 'ㅈ' is not touched, the process proceeds to step S16 to display consonants or vowels arranged on the touched key in the input window area 210. Display.

On the other hand, when the determination result in step S15, if one of the keys arranged '', '' '' '' '' '' '' among the basic consonants is touched (step S17) In step S15, the display of the consonant input key is switched to the consonant of the basic consonant arranged on the touched key in step S15. In other words, when the key with 'a' among the basic consonants is touched, the display of the double consonant input key is switched to the twin consonant 'ㄲ'. To double consonant 'ㄸ', and when the key with 'ㅅ' among basic consonants is touched, the display of the double consonant input key is switched to double consonant 'ㅆ', and the key with 'ㅈ' among basic consonants When touched, the display of the double consonant input key is switched to the double consonant 'ㅉ'.

Next, in step S18, it is determined whether the consonant conversion key is touched, and if the consonant conversion key is not touched, the process proceeds to step S19 and outputs the basic consonant touched in step S15. If the consonant conversion key is touched, the process proceeds to step S20, and the condensed consonant of the basic consonant corresponding to the touched key in step S15 is converted and displayed on the input window area 210. That is, when the key of the basic consonants and the consonant conversion key arranged with 'a' are sequentially touched, the consonant is converted into the consonant 'ㄲ' and input. When touched by, the consonant 'ㄸ' is converted and inputted, and when the key is placed with 'ㅅ' among the basic consonants and the consonant conversion key is sequentially touched, the consonant 'ㅆ' is converted and inputted. When the arranged key and the consonant conversion key are sequentially touched, the consonant is converted into a consonant 'ㅉ' and inputted.
