As shown in the figure, the character input device 100 of the device with a touch screen according to this embodiment includes a consonant keyboard display unit 110, a consonant selection unit 120, a vowel keyboard display unit 130, The drag detection unit 140 and the vowel selection unit 150 are included.

The consonant keyboard display unit 110 displays a consonant keyboard. When entering a text input mode such as writing a text message, the text input apparatus 100 displays the consonant keyboard as shown in FIG. 2 on the touch screen via the consonant keyboard display unit 110. FIG. 2 is a diagram illustrating an example of a Hangul consonant keyboard, and it can be seen that consonants are displayed.

The consonant selector 120 receives any one consonant from the consonant keyboard displayed by the consonant keyboard display 110. For example, the consonant selector 120 may select a consonant by sensing a touch of one of the consonants displayed on the consonant keypad displayed on the touch screen.

At this time, the consonant selector 120 may select a hard sound by detecting a double touch of any one of the consonants displayed on the consonant keyboard. For example, the horn refers to 'ㄲ', 'ㄸ', 'ㅃ', 'ㅆ', 'ㅉ', etc. among Korean consonants.

For example, when the consonant selector 120 holds any one of the consonants displayed on the consonant keyboard while being touched or double touched, the consonant selector 120 determines that the consonant input is the initial input. When the vowel keyboard is displayed through the display 130 and the touch off is performed without holding, the consonant keyboard may be displayed through the consonant keyboard display unit 110 by determining that it is a final input. Conjunctival or final judgment will be described later.

The vowel keyboard display unit 130 displays the vowel keyboard centered on the consonants selected by the consonant selector 120. When a consonant is selected by the consonant selector 120, the character input apparatus 100 displays a vowel keyboard centered on the selected consonant as illustrated in FIG. 3 through the vowel keyboard display 130. FIG. 3 is a diagram illustrating an example of a Korean vowel keyboard displayed when 'ㄱ' is selected as a consonant in the Korean consonant keyboard, and it can be seen that vowels are arranged around the consonant 'a'.

The drag detection unit 140 detects a drag operation having a consonant at the center of the vowel keyboard displayed by the vowel keyboard display unit 130 as a starting point for a predetermined time. When the vowel keyboard is displayed on the touch screen by the vowel keyboard display unit 130, the user drags the vowel desired to be input with the consonant of the center of the vowel keyboard as a starting point.

The text input device 100 detects, for a predetermined time, a drag operation performed by a user whose consonant at the center of the vowel keyboard displayed by the vowel keyboard display unit 130 is a starting point through the drag detection unit 140. .

The vowel selecting unit 150 neutrally selects at least one vowel included in the drag path when the drag detecting unit 140 detects a drag motion. When the drag operation is detected by the drag detection unit 140, the text input device 100 selects at least one vowel included in the drag path having the consonant of the center of the vowel keyboard through the vowel selection unit 150 as a starting point. do.

Referring to FIG. 3, it can be seen that 'ㅏ' and 'ㅗ' are included as a vowel on a drag path (indicated by an arrow in the drawing) starting from the consonant 'a' at the center of the vowel keyboard. Thus, the entered character becomes 'and' with consonant 'a' and vowel '와' and 'ㅗ' combined.

FIG. 4 shows that '와', '.' And 'ㅗ' are included as a vowel on a drag path (indicated by an arrow in the drawing) starting from the consonant 'o' at the center of the vowel keyboard. '.' In the figure means that one stroke is added. Thus, the input character becomes 'why' with one more stroke in 'wa' combining consonants 'ㅇ' and vowel 'ㅏ' and 'ㅗ'.

FIG. 5 shows that 'ㅕ' and '.' Are included as a vowel on a drag path (indicated by an arrow in the drawing) starting from the consonant 'o' at the center of the vowel keyboard. '.' In the figure means that one stroke is added. Thus, the input character becomes 'Yes' with one more stroke in 'Y' combined with the consonant 'ㅇ' and the vowel 'ㅕ'.

However, when adding one more stroke in 'ㅕ', there are two cases of 'ㅖ' and 'ㅒ', in which case it can be determined depending on which is included earlier in the drag path. When 'ㅕ' is included before '.' As shown in FIG. 5, it becomes 'ㅖ', and although not shown in the drawing, '.' Is included when '.' Is included before 'ㅕ'.

Meanwhile, 'ㅓ' included in the drag path of FIG. 5 may be recognized as a subset of 'ㅕ' and ignored.

Therefore, the character input device 100 of the device with the touch screen according to this embodiment displays a consonant keyboard and selects one consonant therefrom, and displays a vowel keyboard centered on the selected consonant and collects it therefrom. It is more intuitive and easy in the character system including consonants and vowels by detecting drag motions using the consonant of the keyboard center as a starting point, and receiving characters by selecting at least one vowel included in the drag path as neutral when detecting the drag motion. It has the convenience of inputting characters on the touch screen.

On the other hand, according to an additional aspect of the present invention, the character input device 100 of the device with the touch screen may further include a first / final determination unit 160. The initial / final determination unit 160 determines whether the consonant input through the consonant keyboard displayed after the vowel is selected by the vowel selection unit 150 is initial or final. This embodiment is an embodiment for determining whether a consonant inputted in a character system composed of a consonant, a neutral, and a consonant, such as Korean, is a consonant or a neutral.

 For example, after the vowel is selected by the vowel selection unit 150 by the initial / final determination unit 160, the consonant consonants are consonant through the consonant magnetic plates within a set time in the state where the consonant magnetic plates are displayed by the consonant magnetic panel display unit 110. If it is input, it can be implemented to determine that the input consonant as the finality.

That is, the touch off without holding any one of the consonants on the consonant magnetic panel displayed by the consonant magnetic keypad display unit 110 in the touch or double touch state through the consonant selector 120. In this case, the initial / final determination unit 160 determines that it is a final input, and displays the consonant magnetic panel through the consonant magnetic panel display unit 110.

For example, after the vowel is selected by the vowel selector 150 by the initial / final determination unit 160, the consonant consonants through the consonant consonants after a set time in a state where the consonant consonants are displayed by the consonant consonant display unit 110. If it is input, it can be implemented to determine the input consonant as a consonant.

In other words, any one of the consonants on the consonant magnetic panel displayed by the consonant magnetic keypad display unit 110 is touched or double-touched through the consonant selector 120 to be held. When the touch is off, the initial / final determination unit 160 determines that the initial entry is made, and the vowel keyboard is displayed through the vowel keyboard display unit 130.

Meanwhile, according to an additional aspect of the present disclosure, the character input device 100 of the device with the touch screen may further include a character display unit 170. The character display unit 170 displays a combination of consonants selected by the consonant selector 120 and vowels selected by the vowel selector 150.
