A Korean input device using a touch screen and a method thereof are provided.

With the recent miniaturization of electronic devices and the emergence of touch screens as core technologies, new text input methods are required to replace existing input keys.

In particular, Koreans are much more likely to input Hangul than when entering English. Therefore, it is urgent to develop a miniature character input device provided with a keypad designed to easily input Hangul.

Known Korean Patent Publication No. 1999-65826 is composed of a phoneme combination method, it is a concept of using a phoneme can easily learn the keystroke method of the character, but requires a large number of times in the vowel configuration.

In addition, Korean Patent Publication No. 1999-52447 is constructed by visual reinterpretation, and it is a system deviating from the basic algorithm of Hangul because it is necessary to reconstruct the consonant, and it requires not only a large number of keystrokes to input the consonant, but also There is a discomfort that can not be easily learned how to key.

In addition, referring to Korean Patent Registration No. 159191, it is not possible to reduce the number of keystrokes when entering consonants, and it is difficult for a user to grasp a writing order when inputting multiple vowels. That is, the conventional Hangul input method has a problem that the number of keystrokes is too large, so that an incorrect input due to an increase in the number of keystrokes is increased, and the character input takes too much time.

Accordingly, an object of the present invention is to provide a Korean input method using a touch screen that enables a simple and fast Korean input by dramatically reducing the number of touches by minimizing the character input keys disposed on the touch screen. .

With respect to the embodiments of the present invention disclosed in the text, specific structural to functional descriptions are merely illustrated for the purpose of describing embodiments of the present invention, embodiments of the present invention may be implemented in various forms and It should not be construed as limited to the embodiments described in.

Hereinafter, with reference to the accompanying drawings, it will be described in detail a preferred embodiment of the present invention. The same reference numerals are used for the same constituent elements in the drawings and redundant explanations for the same constituent elements are omitted.

Throughout the specification, when a part includes a certain component, this means that it may further include other components, without excluding other components unless otherwise stated. In addition, the terms ... unit, ... unit, module, block, etc. described in the specification means a unit for processing at least one function or operation, which may be implemented in hardware or software or a combination of hardware and software. have.

According to the present invention, a consonant input key is first touched (first touch) to input an initial consonant, and again touches a point of a touch screen in a predetermined direction from the consonant input key while maintaining the touch state of the consonant input key again. (2nd touch) displays and determines the vowels to be coupled to the consonants. In the present invention, the vowel is first determined by the direction of the selected consonant input key and the number of touches (ie, the number of second touches).

1 is a step diagram of a Hangul input method of the present invention.

Referring to FIG. 1, the Hangul input method starts with a step in which a user first touches a consonant input key of a touch screen (S110). Here, the consonant of the Hangul syllable is determined by the touched consonant input key. In the present invention, the first touch is maintained in a touch state, wherein other consonant input keys other than the consonant input key in which the touch state is maintained are not activated. That is, the consonants of the other consonant input keys are not input even when the other consonant input keys are touched as long as the touch state is maintained.

Thereafter, in a state in which the first touch on the consonant input key is maintained, the user makes a second touch on a point of the touch screen spaced apart from the consonant input key in a predetermined direction (S120). That is, a vowel in which the first consonant is combined by the first touch and the first consonant by the second touch is displayed on the touch screen. In particular, in the present invention, the vowels displayed in combination with the supersound are determined according to the number of touches of the second touch performed simultaneously or continuously with the direction from the consonants.

After displaying the vowel by the second touch, the user then releases the first touch to input the initial consonant displayed on the touch screen and the neutral vowel combined therewith as the basic unit of the Korean syllable (S130).

2 is a flowchart illustrating a Hangul input method according to another embodiment of the present invention.

Referring to FIG. 2, while maintaining a first touch state for a consonant consonant (S210), a user touches a point of the touch screen spaced apart from the consonant input key in a predetermined direction to determine a short vowel (S220). . In one embodiment of the present invention, the vowel direction of the short vowels, in particular the vowel vowels, is determined according to the input direction of the second touch with respect to the consonant input key. "ㅓ" on the left, "ㅗ" on the top, and "ㅗ" on the bottom are selected as short vowels. In the present specification, the short vowel means four basic vowels of "ㅏ", "ㅓ", "ㅗ", and "ㅗ", and the fold vowel is "ㅑ", "" ㅕ "," ㅛ "with a lower lower added to the short vowel. In addition, in the present invention, the direction of the second touch for determining the short vowel does not mean a direction calculated correctly from the consonant input key, but extends in a predetermined direction from the consonant input key. It should be understood as an area with an angular range of magnitudes.

If the short vowel is selected as the neutral of the Hangul syllable, the Hangul input may be terminated at step S220. However, in the present invention, in consideration of the case of inputting the vowels in Korean, if the short vowel is not a selection vowel (S230), the second touch is repeated two or more times within a predetermined time to change the short vowel displayed in step S220 to the vowel, The consonants are combined and displayed on the consonants (S240). If the second touch is performed for more than a predetermined time, the second second touch is not a touch for determining the neutral vowel, but a touch for determining the next Korean syllable.

When the Hangul syllables combining the desired first and middle voices are displayed, the user releases the touch state of the first touch to select the first + neutral Hangul syllables displayed on the touch screen (S250). Thereafter, the final consonant may be input separately. Here, the release of the touch state simply means that the finger and the stylus pen are separated from the touch screen so that no further touch input is performed.

The present invention also maintains the touch state of the first touch on the consonant, while the method of determining the vowels by the second touches spaced in a predetermined direction is the same as described above, but is applied to a single or dual touch that proceeds substantially simultaneously. Accordingly, a new Korean input method for determining a single vowel or a double vowel is provided.

3 is a flowchart illustrating a Hangul input method according to an embodiment of the present invention.

Referring to FIG. 3, after the first touch S310 for consonants, the second touches any point (s) of the touch screen spaced apart in a predetermined direction while maintaining the first touch (S320). The direction of the vowel is determined according to the direction of the second touch as described above, but it is determined whether the second touch is a single touch that touches only one point substantially simultaneously (S330). If the second touch is a single touch, a short vowel is determined, coupled to the primary consonant, and displayed (S340). Alternatively, when two or more points are touched at substantially the same time (multi-touch), in particular, when two points are touched at the same time (double touch), a layered combination is displayed in combination with the initial consonants (S350).

After that, the Hangul syllable selected and displayed in the previous step is input by releasing the touch state of the first touch.

Another embodiment of the present invention may simply add a stroke according to dragging from the point (s) after simply touching the point (s) spaced in a predetermined direction from the consonant input key, which will be described in more detail below. do.

Hereinafter, a Hangul input example according to the present invention will be described with reference to the accompanying drawings.

4A to 4F are diagrams illustrating a Hangul input method according to an embodiment of the present invention.

Referring to FIG. 4A, a plurality of consonant input keys 420 are disposed at the center of the touch screen 410 as an input window. In particular, the separation distance between the consonant input key and the touch screen provides a space for the user to touch the touch screen to determine the vowel.

Referring to FIG. 4B, the user first touches any one of the plurality of consonant input keys 430. Thus, the consonant is selected and displayed on the output window of the touch screen.

Referring to FIG. 4C, a second touch is performed on a point 440a of the right region of the “a” consonant, wherein the first touch at 430 maintains a touch state.

The vowel “” is selected according to the second touch in the right direction, and the consonant selected by the first touch and the vowel selected by the second touch are combined, and “ga”, which is a (partly) completed Korean syllable, is displayed. Is displayed.

4D to 4F show the Hangul input results when the second touch is made in the up, down and left directions, respectively.

4D to 4F, it can be seen that the short vowels, in particular the short vowel directions, are determined according to the direction between the second touch points 440b, 440c, and 440d and the first touched consonant input key 430, respectively.

FIG. 5 illustrates a Hangul input result when a second second touch is made in the right direction within a predetermined time after the first second touch in FIG. 4C.

Referring to FIG. 5, one more stroke is added to the vowel “” shown in FIG. 4C, resulting in a lap “ㅑ”. The second second touch of the present invention may or may not be the same as the first second touch, but at least in the same direction from the consonant input key.

5A to 5C illustrate a Hangul input method according to another embodiment of the present invention.

Referring to FIG. 5A, after a user first touches any one of the plurality of consonant input keys 510, the second Hangul syllable is completed by second touching to the right again.

However, in FIG. 5A, it can be seen that a short vowel is displayed by combining only one point of the right area from the consonant input key. However, unlike FIG. 5A, FIG. 5B is an input result when two arbitrary points of the right region are touched at the same time. In FIG. 5B, the overlapping bar is displayed and combined. That is, another embodiment of the present invention determines a single vowel or a double vowel according to the number of touches performed substantially simultaneously (in the case of FIG. 4). Thus, the input time for Hangul input can be reduced. Referring to FIG. 5C, an input result after dragging by a predetermined distance after the second touch in FIG. 5A or 5C is illustrated.

Referring to FIG. 5C, another stroke is added according to dragging, in which a stroke is a "|" collection added to a short vowel or a double vowel. Thus, "ㅏ" becomes "는" and "ㅑ" becomes "ㅒ". As such, one embodiment of the present invention adds the "|" collection according to dragging. This can also be applied to the embodiment of Figs. 4A to 4C, which is within the scope of the present invention, and the interval between the input window on which the consonant input keys are arranged and the touch screen has a technical significance as an area for performing such dragging.

The present invention provides a Hangul input device for enabling a Hangul input method on the touch screen.

6 is a block diagram of a Hangul input device according to an embodiment of the present invention.

Referring to FIG. 6, a Hangul input device according to an embodiment of the present invention combines and completes Hangul according to a user touch input and a dragging gesture from a consonant input key of a touch screen, and the touch screen input device includes a consonant input key. Is displayed and includes a touch screen 610 on which an input result is output. Any touch method such as a resistive film or an electrostatic method may be used as the touch screen. In addition, the Hangul input device of the present invention includes a touch detector 620 for detecting a touch on the touch screen, the touch detector 620 is not only a sensor provided in the touch screen, but also detected electrical signals, etc. It includes all the processors in the series that compute touch coordinates through.

The Hangul input device according to the present invention includes a character combining means 630. The character combining means 630 determines an initial consonant by a first touch of the consonant input key and maintains the first touch. In the state, a vowel combined with the initial consonant is determined by a second touch on a point of the touch screen spaced apart from the consonant input key in a predetermined direction. That is, the character combination means 630 determines the direction of the short vowel according to a predetermined direction. The right vowel is selected, the right is "ㅏ", the left is "ㅓ", the top is "ㅗ", and the bottom is "ㅗ". Furthermore, if the second touch is repeated twice within a predetermined time, the short vowel is changed into a lap vowel, as described with reference to FIG. 4. In addition, the "|" collection may be added according to subsequent dragging.

A Hangul input device according to another embodiment of the present invention using a multi-touch has the same configuration as that of FIG. 6, wherein the character combination means touches only one point within an area spaced in a predetermined direction from the consonant input key or two. The single vowel or the double vowel is determined depending on whether the dog touches. That is, if the predetermined direction is the right side of the consonant input key touched with consonant consonants, "ㅏ" or "ㅑ" is determined as a vowel. Is determined by the input bar. Similarly, "소정" if the predetermined direction is left, "ㅗ" if the upper direction, "ㅗ" if the downward direction is selected and displayed as a single vowel. This is determined. Furthermore, as described above, the "|" vowel may be further added according to the dragging performed continuously from the second touch.

Furthermore, according to another embodiment of the present invention, after the first touch of the consonant input key, the second consonant of the touch screen by the second touch while maintaining the first touch state, the consonant sounds, the consonant form Can be changed to

For example, when the consonant "a" is first touched and touched another point once (second touch), the "a" is changed to a broken sound "ㅋ". Thereafter, the vowel may be determined according to the dragging gesture. For example, the drag may be determined as "vo" if the dragging is right, "ㅓ" if the dragging is left, "ㅗ" if the dragging is upper, and "TT" if the dragging is lower. Furthermore, when the second number of touches is performed twice, the burst sound may be changed to a double consonant so that "ㄲ" is displayed on the consonant input key. As described above, not only vowels but also consonants may be input in various forms by selecting a desired consonant input key, which is within the scope of the present invention.

The Hangul input device and method according to the present invention is particularly applicable to any electronic device based on a touch screen, for example, a portable terminal, a PMP, a notebook, and the like.
