Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figure 1 showing the overall configuration of the present invention, the present invention is a storage unit (3) for storing the data of the screen keyboard for numeric or character input, the control screen keyboard consisting of function buttons, the numeric input screen keyboard, Selection information of the touch panel 1 and the touch panel 1 which display the character input screen keyboard and the control screen keyboard and transmit selection information to the control module 2 when the user selects a specific button displayed on the screen. It consists of a character generation module 4 for receiving the character to generate a character, and a control module 2 for controlling the storage unit 3, the touch panel 1, the character generation module (4).

The control module 2 selects and displays different types of function buttons of the control screen keyboard according to the type of the character input screen keyboard. When the character input screen keyboard displayed on the touch panel 1 is the Korean input screen keyboard, the English input keyboard switching function button is displayed on the control screen keyboard, and when the English input screen keyboard is displayed, the Korean input keyboard switching function button is displayed. do.

When the character input screen keyboard 12 for Hangul input is displayed on the touch panel 1, the control unit 2 controls the function buttons of the control screen keyboard 11 as shown in FIG. , Numeric keyboard toggle button, keyboard switch button, enter button, initial double consonant button, keyboard removal buttons are read from the storage unit 3 to generate and display the control screen keyboard (11).

The control module 2 controls the storage unit 3 and the character generation module 4 according to the selected information on which the button of the control screen 11 is selected. When the keyboard switching button is selected, the keyboard is read from the storage unit 3 and displayed on the touch panel 1, and when the specific button of the character input screen keyboard 12 is inputted, the character generating module 4 is loaded. Activate to generate text, and display the created text in the text editing window of the touch panel.

In addition, the control module 2 reads the numeric screen keyboard separate from the character input screen keyboard from the storage unit 3 when the numeric screen keyboard toggle button of the control screen keyboard 11 is selected once. As shown in FIG. 4, when the numeric keypad toggle button is selected again, the numeric keypad of the displayed touch panel is deleted. As such, when a numeric screen keyboard is required, the display is performed using a toggle button, and when the numeric screen keyboard is unnecessary, the numeric screen keyboard is erased so as to efficiently use the display space of the touch panel, and conveniently enter numbers and characters in parallel. Make sure

In this case, the control screen keyboard 11 may be separated from the text input screen keyboard 12, and may be displayed below the text input screen keyboard 12.

Table 1 below describes the functions of the function keys of the control screen keyboard 11.

The character input screen keyboard 12 for the Hangul input of the first embodiment includes six Hangul vowels ㅏ, ㅓ, ㅗ, TT, ㅡ, ㅣ button, and 14 Hangul consonants a, b, c, ㄹ, ㅁ, ㅂ, ㅅ It consists of four buttons: ,,,,,,,,,,,,, and, these buttons are arranged in four rows and six columns. In this case, 1, ㅓ, ㅗ, TT, ㅡ, ㅣ buttons are arranged in 1, 2, 3 rows of 3, 4 columns, and consonants a, b, c, d, ㅁ, ㅂ, ㅅ, ㅇ in the 1st and 2nd columns. In the 5th and 6th columns, the buttons ㅈ, ㅋ, ㅋ, ㅌ, ㅎ, ㅎ are arranged so that the buttons are arranged in a 'to go' order so that the user can easily remember them. In addition, the Space button is arranged in the 3rd and 4th row of 4 rows to move the cursor in the document editing window.The 5th column of the 4th row has a comma ',' button, and the 4th row has 6 columns. The period '.' Button is placed.

The 6 vowel buttons ㅏ, ㅓ, ㅗ, TT, ㅡ, ㅣ are placed in 1, 2, 3 rows of 3, 4 columns, which are the center of the character input screen keyboard, and consist of Korean initial, neutral, and final Since consonants and vowels should be selected alternately to form a letter, it is to minimize the moving distance of the input tool, that is, the stylus pen when entering letters.

When the consonant vowel button is selected on the touch panel 1, selection information is input to the character generation module 4, and the character generation module 4 generates a character by an internal program to create a document editing window of the touch panel 1; Display it by sending it.

The character generation module 4 generates 21 vowels using six vowel buttons on the character input screen keyboard. The generation methods are shown in Table 2 below.

In Table 2, double selection means selecting the same button twice in succession.

In the case of Cheonjiin, a combination of '·', 'ㅡ', 'ㅣ' is used to form a vowel. When applied to the screen keyboard of the touch panel, the number of touches increases, and thus the frequency of error occurrences increases. For example, in order to input a basic collection such as 'ㅏ', it is inconvenient to select one movement and two selections, such as 'ㅣ' → (move) → '·'. It is convenient because a collection can be created by one selection on the displayed screen keyboard to create a.

In addition, in the case of narral method, all vowels are combined using only 6 vowels of 'ㅏ', 'ㅓ', 'ㅗ', 'ㅜ', 'ㅡ', 'ㅣ' / It has a submit button. To create a collection of 'ㅑ', 'ㅕ', 'ㅛ', 'ㅠ', press 'Submit', 'ㅓ', 'ㅗ', 'TT', and then click Submit. do. For example, in order to input 'ㅕ', one movement and two touches of 'ㅏ' → (move) → 'Submit button' occur. However, in the first embodiment, the use of six vowels of ',', 'ㅓ', 'ㅜ', 'TT', 'ㅡ', and 'ㅣ' is the same as the narrative method, but 'ㅑ', 'ㅕ' When creating, 'ㅛ', 'ㅠ', you can conveniently input only by double selection.

Table 3 below compares the number of movements and the number of selections in the vowel generation of the Cheonjiin and Naraggle methods with the first embodiment.

As can be seen from Table 3, it can be seen that the number of selection of buttons and the number of movements of the stylus pen of the first embodiment are smaller in the vowel generation method and the naraggle method in the vowel generation method.

In addition, in the first embodiment, in the case of consonants constituting a consonant and a finality, 'a', 'b', 'c', 'r', 'ㅁ', 'ㅂ', 'ㅅ', 'ㅇ', ' You can create 14 basic consonants of 'J', 'ZH', 'ㅋ', 'ㅌ', 'ㄷ', 'ㅎ' by selecting the corresponding button on the keyboard. By selecting the 'ㅂ', 'ㅅ', 'ㅈ' button twice, you can create five double consonants 'ㄲ', 'ㄸ', 'ㅃ', 'ㅆ', 'ㅉ'. Blessed consonants of 'ㄳ', 'ㄵ', 'ㄶ', 'ㄺ', 'ㄻ', 'ㄼ', 'ㄽ', 'ㄾ', 'ㄿ', 'ㅀ' and 'ㅄ' The dog can be generated by successively selecting two basic consonant buttons, each of which produces a double consonant among the fourteen basic consonants.

In the case of Cheonjiin method, a consonant is changed according to the number of button selections, which increases the number of button selections. For example, the 'b' button is selected once, 'b' is selected twice, 'ㅋ' is selected twice, and 'b' is selected three times. It is inconvenient to increase. In the case of the narrative method, a method of making consonants using the auxiliary button of the catch / dose is based on the six consonants of 'ㄱ', 'ㄴ', 'ㅁ', 'ㅅ', 'ㅇ', and 'ㄹ'. use. For example, the stylus is applied as 'ㄷ': 'b' → 'capture button', 'ㅌ': 'ㄴ' → 'stroke button' 2 touches, and 'ㄲ': 'ㄱ' → 'dose button' Due to the increase in the pen's mobility and the number of button selections, the input speed and the frequency of input errors increase.

In addition, the characteristics of the Korean characters should be input by distinguishing the case where the initial letter of the first letter and the initial letter of the last letter are the same consonant and the first letter is the initial consonant, and the next letter is the double consonant. For example, if the phrase 'gu' → 'ㄱ' (double touch) → 'l' is input, it is necessary to distinguish whether the corresponding letter is 'national flag' or 'cub'.

The first embodiment provides a shift button to solve the above problem. If the same consonant is selected twice after the neutral of the first letter is selected, the first choice is placed as the last letter of the first letter, and the next choice is placed as the first letter of the latter letter. In order to make the consonants of the back letters into double consonants, press the corresponding basic consonant button to make the double consonants once, and then press the shift button to generate the consonant consonants. For example, 'dad' is generated by pressing 'ㅇ' → 'ㅏ' → 'ㅂ' → 'Shift'.

In addition, when the same consonant is input three times in the final consonant, two are consonants of the final consonant and the remaining consonants are treated as the first consonants of the next letter. For example, when the expression 'go' is generated, 'ga' → 'ㅅ' (3 times touch) occurs, it is processed as 'go'.

3 is a second embodiment of a character input screen keyboard of the present invention.

As shown in Figure 3, the constitution of the consonants in the Hangul keyboard 'b', 'b', 'c', 'ㄹ', 'ㅁ', 'ㅂ', 'ㅅ', 'ㅇ', 'ㅈ' , 'ㅎ' consists of only 10, and the vowels (')', 'ㅋ', 'ㅌ', and 'ㄷ' double 'ㅈ', 'ㄱ', 'ㄷ' and 'ㅂ' Select to create

Also, the consonant 'ㄲ', 'ㄸ', 'ㅃ', 'ㅆ', ',' means the basic consonants 'ㄱ', 'ㄷ', 'ㅂ', 'ㅅ', 'ㅈ' Select the consonant button "pair / za" on the keyboard.

In the case of the naragle system, consonants are generated by providing six consonants, 'a', 'b', 'ㄹ', 'ㅁ', 'ㅅ', and 'ㅇ' and a separate capture button. In other words, 'ㅊ' is generated through 'ㅅ' → 'stroke button' (two touches), so it is difficult for users to master because they press irrelevant consonants. Due to the increase in the number of errors occurs when the implementation on the touch panel has a problem that the input speed is lowered.

 Samsung Electronics' mobile phone name 'Anycall', which adopts the Cheonjiin method, is used to create '음', 'ㅋ', 'ㅌ' and 'ㄷ' 'Is created by double-selecting, but if the last letter and the first letter are the same consonants, the same consonants must be selected twice in succession. For example, in order to create a 'country', 'a' is the same as the initial letter 'a' and the first letter 'a' is the same, so 'b' is selected twice in succession. Kuka 'will be generated. In order to solve this problem, Samsung's mobile phone is generated as 'country' because the selection time is large when the same consonant key is selected twice. In this case, it is recognized as a sound sound and is generated as 'Kukah'. However, such a selection time difference requires mastery and can cause a large number of errors for an untrained user.

In the second embodiment, in order to solve this problem, the front letter and the first letter are the same consonants, so that the consonant button is selected twice, and the front letter is disappeared and the first letter is generated as a vowel sound. In addition, the consonant button is additionally selected so that the input consonants are placed at the front end of the initial letter and the beginning of the rear letter. For example, in order to create a 'country', a selection process of 'ㄱ' → 'TT' → 'ㄱ' → 'ㄱ' → twin consonant button → 'ㅏ' is performed.

Thus, in the second embodiment, the consonant button is used to convert the consonant to the consonant, and the consonant is selected twice so as to be related to each other by using it to separate the changed quartet into the initial letter and the initial letter of the latter letter. Therefore, the number of selection buttons can be reduced while making it easier for the user to remember.

According to the present invention having the above object and configuration,

(1) By disposing the character input screen keyboard and the control screen keyboard together on the screen of the touch panel, the inconvenience of having to use the physical keyboard installed in addition to the touch panel alternately can be eliminated.

(2) Character input The function buttons on the control screen keyboard can be switched according to the type of the keyboard to conveniently input text.

(3) Number input screen keyboard can be activated as needed, so it is convenient to input letters and numbers simultaneously.

(4) When selecting the Korean alphabet button on the screen keyboard, the input time is minimized by arranging to minimize the moving distance of the stylus pen.

(5) By optimizing the number of selection buttons on the character input screen keyboard and the selection buttons on the control screen keyboard, it is possible to reduce the size of the screen keyboard and to input conveniently without an error during input.
