FIG. 3 shows a software Hangul keypad according to a second embodiment of the present invention.

3, a character of "a, b, c" is represented by a position of (1.1), and a character of "b, d" (2, 2), except that the characters " c, " and " Is the same as the software Hangul keypad according to the first embodiment of the present invention. Therefore, detailed description of the software Hangul keypad according to the second embodiment of the present invention will be omitted (refer to the explanation of FIG. 2).

Next, in step S120, a first key of the twelve key buttons detects touch in the area of the touch screen displayed.

In step S130, one of two or more characters corresponding to the first key button is input to the text box displayed on the touch screen based on the touch pattern.

According to an embodiment of the present invention, when the touch pattern corresponds to touching the main button area of the first key button, the main character corresponding to the first key button is input to the text box, When the touch pattern corresponds to moving the touch to the first sub-button area of one or more sub-button areas of the first key button in a state where the touch is maintained after touching the main button area of the first key button, The sub-button displayed in the first sub-button area of the key button can be input to the text box.

For example, in a software Hangul keypad according to the first embodiment of the present invention, when the user touches the main button area of the key button at the position of (1, 1) in the keypad displayed on the touch screen, "F" is input. If the user moves the touch to the left sub-button area of the corresponding key button in the state where the user touches the main button area of the key button at position (1, 1) and holds the touch, .

As another example, when the user touches the main button area of the key button at the position (4, 3) in the keypad displayed on the touch screen in the software Hangul keypad according to the first embodiment of the present invention, Quot; is input. If the user moves the touch to the lower sub-button area of the corresponding key button in a state where the user touches the main button area of the key button at the position of (4, 3) and the touch is maintained, "ㅞ" .

Hereinafter, the reason for arranging characters on the keypad and the effect of the present invention will be described in detail.

Hangul has the characteristic of making a letter by combining consonants and vowels. Therefore, when the consonants and vowels frequently used by the users are arranged close to each other, the distance of movement of the fingers is reduced, and the input speed of the word / sentence becomes faster.

In the analysis of the frequency of use of Korean, published by Korea University 's Institute of Korean Language and Culture, 29,512,693 Korean speakers were divided into two groups, first, second, and last. In this specification, the frequency of use of consonants and vowels was calculated based on this calculation, and the frequency of use of consonants was calculated as the sum of frequencies of use of first and last consonants. In the case of double words such as 'ㄳ' , And each consonant was calculated one time. Table 1 and Table 2 below show the usage rates of the respective representative tones together with the usage rates of the consonants and vowels by classifying them into 7 representative consonants and 5 representative vowels in frequency of use of consonants and vowels.

On the basis of the contents of Tables 1 and 2, in the present invention, similar types of consonants / vowels are grouped into two to five groups (divided into bold lines in Tables 1 and 2) Quot; key " In addition, "ㅇ, ㄴ, ㅅ, ㄱ" consonants which are frequently used consonants among the representative consonants of each group, and "a, ㅣ" which is a frequently used vowel among representative vowels are arranged in the center and arranged close to each other. Also, in the relatively low consonants "b, c, i", "i" is placed in the button nearest to "g", and "b" in the lowest usage rate is placed in the button located farthest. Also, in the case of the vowels, "ㅣ" having the highest usage rate is arranged on the right side of "ㅇ", "a" having the next highest usage rate is arranged in the middle, and "ㅓ" having a low usage rate is arranged on the uppermost side.

FIG. 4 is a diagram illustrating a simulation result of input performance of a conventional software Hangul keypad and software Hangul keypads according to the first and second embodiments of the present invention.

4, the simulation was performed by measuring the number of touches of the keypad and the moving distance of the finger while inputting the national anthem as shown in Table 3 below and the Hunminjeongeum as shown in Table 4 below.

The East Sea and Mt.
God blessed our country.
Mugunghwa Samchully Gorgeous Gangsan
Keep the length of the Korean people alive.

I will put the letters and words together in the middle
If the tribe of the tribe is too young
After all, it is the one who can not do my will.
My mouth is full of sorrows, and I am a new twenty-eight.
Every person has a bottle of beanie,

Here, the number of touches is the total number of times a button is pressed to input a consonant or a vowel, and the moving distance is a sum of the distance that the user moves the finger to select the next button after touching or dragging one button. The distance between the buttons is calculated as the distance between the adjacent buttons in the up, down, left, and right directions as '1'. In order to simplify the comparison of the keyboards, it is assumed that the time of touching the button with one finger is the same as the time when the button is moved by the size of the button while touching the finger. The distance was added and the results were compared.

Referring to FIG. 4, it can be seen that the number of touches and the distance of movement of the finger of the software Hangul keypad according to the present invention are reduced as compared with the conventional software keypad. Tables 5 and 6 below show the performance improvement based on the moving distance of the finger in the above simulation based on the national anthem and the Hunminjeongeum.

National anthem Heavenly Father Nagle SKY Hangul First Embodiment 24.4% 21.4% 11.6% Second Embodiment 19.1% 15.9% 5.4%

Hun-Min-Jeong-Eum Heavenly Father Nagle SKY Hangul First Embodiment 22.2% 22.4% 9.6% Second Embodiment 17.0% 17.2% 3.5%

Nielsen and Mack, on the other hand, presented Efficiency, Learnability, Memorability, Errors, and Satisfaction as criteria for evaluating usability in devices. However, the study of Korean character keyboard in general physical keypad tends to be limited to the input speed as a comparative evaluation standard. In the present specification, the following four essential elements and one recommended element are set for comparing and evaluating the performance of the software Hangul keypad in a smart device (for convenience of description, five evaluation elements are referred to as "SELF-T" ).
