[0001] KEY PAD FOR INPUTTING KOREAN CHARACTERS [0002]

The present invention relates to a keypad for inputting Hangul characters, and more particularly, to a keypad for inputting Hangul characters using both hands.

Today, mobile communication terminals are becoming a necessity for life.

Recently, a mobile communication terminal recently released includes a number of functions in addition to a voice call function. Of these, a SMS (Shot Message Service) function, a mobile communication messenger service function, a phone number storage and memo function, Name search function, and schedule management function.

Therefore, a small mobile terminal such as a mobile communication terminal is required to have a keypad for inputting characters. In general, the conventional keypad for numeric input is used as it is.

The keypad for numeric input has 12 key buttons arranged in 4 rows (row) and 3 columns (colurmn), and numbers 0 to 9 and * and # are inputted.

On the other hand, Hangul is composed of 14 basic consonants (a, b, c, d, k, f, g, h, i, It consists of 10 basic vowels (a, ㅑ, ㅓ, ㅕ, ㅗ, ㅛ, ㅜ, ㅠ, ㅡ, ㅣ) based on consonant (ㄲ, ㄸ, ㅃ, ㅆ, The syllable is composed of an optional combination of vowels (ㅢ, ㅐ, ㅒ, ㅔ, ㅖ, ㅘ, ㅚ, ㅙ, ㅝ, ㅟ, ㅞ).

Therefore, the use of a small keypad that utilizes the conventional keypad for numeric input is limited to 12, and the cognitive load of the user is increased due to the limitation of the number of the limited number of key buttons and the complexity of Hangul.

That is, since a mobile terminal such as a mobile communication terminal has a limitation on its size in order to secure portability, instead of restricting the addition of a separate key button in addition to the conventional numeric key button, (ㄲ, ㄸ, ㅃ, ㅆ, ㅉ), 음 (ㅋ, ㅌ, ㅊ, ㅍ), or composite vowel (For example, a stroke addition button) for inputting a user's desired cognitive load (eg, ㅢ, ㅐ, ㅒ, ㅔ, ㅖ, ㅘ, ㅚ, ㅙ, ㅝ, ㅟ, ㅞ) .

For this reason, efforts are being made to develop an optimized jigsaw arrangement that maximizes usability by minimizing the user's cognitive wealth and usage constraints.

Nielsen (1993) found that there were no significant differences in use-efficiency, ease-to-learn, easy to remember, few errors, It defines the satisfaction of the product (subjectively pleasing). If the Nielsen usability factor is applied to the Hangul input of the mobile terminal, it can be said that the efficiency is reduced by reducing the number of operations and the fingering distance of the button when inputting Hangul by using a mobile phone. It can be said that it should be possible to learn, and the ease of memory can be said by the user whether it is easy to remember the arrangement of the key buttons. And minimization of work error means minimizing the error of key button operation, and satisfaction with the product can be said to be satisfaction with the product that users feel while using Hangul input method.

Such usability must be considered when developing a keypad for Hangul input that is directly related to Hangul input by the developer.

In the beginning of the development of the keypad, the concept of manipulating the twelve key buttons with both hands was not derived due to the limitation of the size thereof. However, in consideration of the usability according to the arrangement of the key buttons optimized for one hand input, As inputting Hangul using hands, the usability considering the arrangement of key buttons optimized for both hands input was considered in the near future.

The object of the present invention is to provide a keypad for inputting a Hangul character having a character arrangement optimized for both hand input.

According to an aspect of the present invention, there is provided a Hangul keypad comprising seven consonant input key buttons and five vowel input key buttons arranged in a row of 3 rows (Colum) Consonants are arranged in the seven consonant input key buttons, vowels are arranged in the five vowel input key buttons, and the five vowel input key buttons are arranged in a reverse (" ") , Key buttons for inputting 'ㅣ / ㅡ' or 'ㅡ / ㅣ' are arranged in the vertex portion of the reverse key shape, and are arranged side by side on the basis of the 'ㅣ / ㅡ' or '揃 / ㅣ' The two key input buttons for vowel input are provided for inputting 'a / b' and 'b / b' having a midway point of the heaven and earth, and '/ /' or ' The two vowel input key buttons, which are arranged side by side in the left direction with respect to the input key buttons, (7) consonant input key buttons are provided for inputting 'ㅗ / ㅛ' and 'ㅜ / ㅠ', respectively, having (person) The key buttons for inputting the a, b, c, and g are provided to be able to input the a, b, c, o, , ≪ / RTI > and < RTI ID = 0.0 > 3, < / RTI >

And the key is input when the key button for inputting the key and the key is operated twice.

More specifically, the key buttons for inputting the '? /?' Or '? /?' Are provided in three rows of four rows.

According to another aspect of the present invention, there is provided a Hangul keypad comprising seven consonant input key buttons and five vowel input key buttons arranged in four rows and three columns, Consonants are arranged in the seven consonant input key buttons, vowels are arranged in the five vowel input key buttons, and the five vowel input key buttons are arranged in a reverse (" ") Key buttons for inputting 'ㅣ / ㅡ' or 'ㅡ / ㅣ' are arranged in the vertex portion of the reverse key shape, and are arranged side by side on the basis of the 'ㅣ / ㅡ' or '揃 / ㅣ' Key buttons for inputting a vowel are provided for inputting 'a / b' and 'b / b' having a person in a heaven or earth, and the 'ㅣ / ㅡ' or 'ㅡ / The two key buttons for vowel input, which are arranged side by side in the upper direction with respect to the key button, The key buttons for the consonant input are provided for inputting 'ㅗ / ㅛ' and 'ㅜ / ㅠ', respectively. And the key buttons for inputting the a, b, c, and g are respectively input to the input keys such as ㄲ, ㄸ, ㅃ, ㅆ, ㅆ, And can be input at the time of three operations.

And the key is input when the key button for inputting the key and the key is operated twice.

More specifically, the key buttons for inputting the '? /?' Or '? /?' Are provided in three rows of four rows.

According to the present invention as described above, there are the following unique effects.

First, users can easily understand the distinctive directionality of the vowel key buttons including 'ㅣ' and the vowel key buttons including 'ㅡ', thereby intuitively recognizing the key buttons. (Easy to learn and ease of memory during usability), the vowel key buttons including 'ㅣ' and the vowel key buttons including 'ㅡ' are separated as well as the vowel input patterns of the clearly distinguished right thumb, (Confusing) and manipulation errors of the vowel key buttons including "ㅣ" and the vowel key buttons including "ㅡ" can be eliminated (minimization of operation error during usability).

(2) The number of key button operations (3 times) for inputting hypothetical sounds can be obtained by arranging the keys in a button for inputting, So that the learning of the hypothetical input method is facilitated.

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

FIG. 1 illustrates a keypad according to an embodiment of the present invention, in which numerals, special symbols (*, #), and syllables are arranged in twelve key buttons arranged in the form of 4 rows and 3 columns. This will be described in detail as follows.

The consonants include seven consonant key buttons for consonant input of one column of 1 row, 2 columns of 1 row, 3 columns of 1 row, 1 column of 2 rows, 2 columns of 2 rows, 2 columns of 1 column of 3 rows, (1, 2, 3, 4, 5, 7, 8 are arranged respectively) Key buttons placed on the second row of the first row on which the number 2 is arranged are key buttons arranged on the third row of the first row in which the keys are arranged in the order of b, (ㅇ / ㅎ) are arranged in the first column of the second row in which the number 4 is arranged, and the key buttons arranged in the second column of the second row in which the number 5 is arranged are the key buttons The key buttons arranged in the first column of the third row in which the number 7 is arranged are the three rows in which the numbers 8, The key buttons arranged in the second column are arranged in the order of ell, ㅊ, ㅉ (/ / / / ㅉ).

In the above consonant arrangement, the letters a, b, c, o, g, and z are provided as representative consonants in which input is performed by a single operation of the key buttons, and d, And the key is provided to perform the input by two key button operations, and the input is performed by the two key button operations of ㄲ, ㄸ, ㅃ, ㅆ, 경.

In addition, the sounds and phonemes that are morphologically similar to the phonemes are arranged in the same keybutton, respectively, but they are arranged in the form of a phoneme, a phoneme, a phoneme, a phoneme, Since there is no sound similar to that of the key button, it is possible to arrange the key button on the same key button as the key button and to input the key button by two operations of the key button, . Therefore, users can easily understand how to operate the key buttons uniformly applied to the tremor input.

On the other hand, the vowel includes five vowel input key buttons (6, 9, *, 0, and 1, respectively) of 3 rows of 2 rows, 3 columns of 3 rows, 1 column of 4 rows, 2 columns of 4 rows, # Are arranged), a key button arranged in the third row of the second row in which the numeral 6 is arranged, a key button arranged in the third column of the third row in which the letter a, the letter (a / Key buttons disposed on the first row of the 4th row on which *, ㅕ (ㅓ / ㅕ) are arranged, and key buttons disposed on the 2 rows of 4 rows in which ㅗ and ㅛ (ㅗ / ㅛ) The key buttons placed on the third row of the 4th row where #, #, and # are arranged are arranged in the form of ㅣ, ㅡ (ㅣ / ㅡ).

In the above vowel arrangement, ㅗ,,,,, ㅓ, ㅣ are provided as representative vowels in which the input is performed by one operation of the key buttons, and ㅛ, ㅠ, ㅑ, ㅕ, So that an input is performed. Of course, in the case of a key button for inputting 'I / /', it is possible to provide a representative vowel according to the actual use frequency (in this case, a key button for inputting '? /?').

As shown in FIG. 1, key buttons for inputting a vowel are arranged in a reverse shape ('' '), and a key button for inputting a' I / .

In general, since a small keypad applied to a mobile terminal or the like inputs only Korean characters using only a thumb, the movement of the thumb for Korean input is natural when the user holds the keyboard with both hands, It is preferable to arrange the key button to position the thumb.

On the other hand, Hangul has 11 complex vowels than the number of basic vowels. It is composed of 11 vowels, ㅢ, ㅐ, ㅒ, ㅚ, ㅙ, ㅝ, ㅟ, ㅞ There is a lot of use of 'ㅣ' key button which is mainly used for compound vowel input.

Also, when holding a small terminal with a keypad for Hangul input, it is the most comfortable gripping position that the thumb is slightly curved. In this posture, the movement of the thumb from the base position to the upper or left direction is convenient, while the movement of the thumb from the base position to the lower or right direction is inconvenient due to the load occurring (the actual mobile phone is not shaken by both hands You can clearly see if you try to skip one button in a vertical direction while holding it steadily).

That is, if the movement vector in the downward direction or the rightward direction is mixed in the movement direction of the thumb with respect to the base position of the thumb, movement of the thumb becomes inconvenient.

Therefore, the keypad of FIG. 1 has a keypad for inputting 'I /' 'so that the movement vector in the downward direction or the rightward direction is not mixed when the thumb is moved from the basic position, When the user holds the small terminal so as to be a 'ㅣ / ㅡ' key button that frequently uses the basic position of the right hand thumb ring, the movement of the right thumb for manipulating the other vowel key buttons is shifted upward , Left direction, or rotation direction ('ㅘ' or 'ㅝ' input).

In the third row and the third row of the upper row 2, the 'a / ㅑ' and the 'ㅓ / ㅕ' having the person (s) Key button for inputting a '/ b' input and a key button for inputting a 'b' / '' are positioned, and ultimately, a key button for inputting 'a / b' The key buttons for inputting 'ㅣ / ㅡ' are sequentially arranged in the downward direction. In the first and second columns of the left 4 rows, 'ㅗ / ㅛ' and 'ㅗ / ㅛ' A key button for inputting '/ / ㅛ' and a key button for inputting 'ㅜ / ㅠ' for inputting 'ㅜ / ㅠ', and ultimately, a key button for inputting 'ㅗ / ㅛ' And the key buttons for inputting "ㅣ / ㅡ" are arranged in order from left to right.

Of course, depending on the execution, the positions of the key buttons for inputting a / b and inputting keys for b / w input can be changed. Similarly, the key buttons for inputting b / The position of the 'key button for inputting can be changed to each other. In this case, ㅣ and 가 are mainly used in the blending vowel, but ㅘ is a pair of ㅗ and,, and ㅝ and ㅓ are combined as a pair. Therefore, as can be seen from the pattern comparison described later, So that the rotation pattern of the thumb can be the same. That is, for example, as shown in FIG. 1, when the 'a' / 'b' input key button is located in the third row of the second row, it is preferable that the ' If the key button for inputting a / b is located in the third row of the third row, it is preferable that the key button for inputting the b / b is located in the second row of the fourth row.

Also, according to the embodiment, the keypad for inputting 'a / b' and the keypad for inputting 'b' / '' are located on the left side of the keypad for inputting ' Button and a key button for inputting '? /?' May be located above the key button for inputting '? /?'.

Next, the operation of the keypad having the above structure will be described.

The keypad of FIG. 1 does not have a separate special function key for inputting Hangul, but instead of sequentially inputting the syllables arranged on the key button in accordance with the Hangul syllabus writing order, all the syllables used in Hangul So that there is no need to learn how to use a separate function key.

In addition, the keypad of FIG. 1 is configured such that the 'a / b' and 'b / b' key buttons are moved by moving the thumb of the right thumb upward, and 'ㅗ / ㅛ' and 'ㅓ / / ㅠ 'key buttons act to reach the thumb by moving the thumb to the left.

Therefore, according to the keypad according to the present invention, as shown in the input pattern of the right-hand thumb shown in FIG. 2, three basic patterns (a pattern in the vertical and vertical directions, Rotation pattern).

And the input of 'ㅘ' and 'ㅝ' (two complex vowels of which the 'ㅣ' is not used) input is made in the same rotation pattern with the thumb slightly stretched or slightly bent.

In this specification, the Korean language input keypad according to the present invention is applied to a mobile communication terminal. However, the present invention can be applied to all small terminals capable of inputting a TV remote control or other Hangul characters, and a touch keypad having a touch screen .

Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying drawings. It is to be understood that the scope of the present invention is to be construed as the scope of the following claims and their equivalents.
