The present invention relates to an apparatus and a method for inputting Korean characters easily and quickly and efficiently using a touch screen of a small terminal such as a mobile phone or a PDA.

According to the present invention, the Hangul alphabet to be input can be selected according to the shape and direction of touch-and-move as well as the touched position. Therefore, Hangul consonants except Bokja consonants can be input with one touch and movement, and vowels can be input with fewer times than the conventional method. According to the present invention, even in a touch screen of a small screen such as a mobile phone or a PDA, Korean characters can be input much more accurately and quickly than a simple touch keyboard type input method.

Description

Hangul input system and method using touch screen, etc. {A method and apparatus for Hangul input with touch screen}

The present invention relates to a system and method for efficiently inputting Hangul using a touch screen in a small terminal such as a mobile phone or a PDA. The present invention includes a system and method for efficiently inputting Korean characters in an input device having a coordinate system even if the input device is not a touch screen type.

Currently, in case of using the touch screen in PDA and mobile phone, in order to input Hangul, a number of Hangul characters are placed on the numeric keys, and one key is pressed several times to select the desired phonemes according to the number of presses. Or, it uses an input method that displays a keyboard that has one-to-one correspondence with character keys and touches it like a computer keyboard.

The first method is to select a character to input depending on how many times the same key is touched in succession. This method is inconvenient to touch the touch screen several times to input a single character. In addition, when it is necessary to continuously input characters arranged on the same key, it is inconvenient to press another key or to stop inputting for the end of selection of the previous character. Of course, if you design the key layout and input method to reflect the principles of Hangul creation, you can increase the convenience of input to some extent. For example, because Hangul is composed of consonants and vowels, the consonants and vowels are divided into groups and placed on each key, but several consonants are placed on one key so that the vowels are sequentially selected as above. Reflecting the principles of Hangeul creation in Cheonjiin, it is possible to improve input convenience in its own way by dividing it into horizontal strokes, vertical strokes, and dots. In this case, however, the same key must be pressed several times when selecting the consonant or the final consonant.If the consonant you want to enter after entering the final constellation is on the same key, you must press another key to signal the end of the final input, as in the previous question. There is inconvenience.

The second method is to display all the Korean keyboard keyboard on the screen and to input by touching a letter key that the user wants to input. It is like moving a computer keyboard to a touch screen screen. This method can input the desired phoneme by touching the touch screen only once.However, if the screen is small, the keyboard key area is small, so it is difficult to press the exact position of the keyboard with a finger or a pen. Even if the screen is large, there is a limit to enlarge the keyboard. If the keyboard is large, the input is not very efficient because a large number of hands must be moved to select a character key.

In order to solve this problem, a Hangul input system and method using a touch screen and the like have been devised. That is, a method of inputting Hangul using touch-and-move. By using the proposed touch and motion-based Hangul input method devised according to the apprentice principle of Hangul, we can dramatically improve the Hangul input method.

The present invention improves the shortcomings of the conventional method, which requires multiple touches or a lot of hand movements when inputting Korean using a touch screen, and minimizes touch and movement, and easily and efficiently uses Hangul with simple touch and movement. Provided are an apparatus and a method for inputting.

Touch-and-Move based Hangul input system is a feature of the present invention for achieving the technical problem of the present invention (100),

A key area setting unit 200 for setting an area of an input key so that a user can view and input Korean phonemes on a touch screen, and configuring a phoneme set for each key and outputting each phoneme to an appropriate position of the key area; A touch signal input unit 300 for processing a signal input by a user with a finger or an electronic pen; A phoneme selector 400 which selects a phoneme to be input by analyzing a direction, a distance, a trajectory, etc. moved in a touched state by a user's touch key; It includes a Hangul character composition unit 500 for forming the Hangul characters in a combination of the selected phoneme or phoneme basic type.

Touch and motion-based Hangul input method is another feature of the present invention for achieving the technical problem of the present invention,

Setting an area of an input key so that a user can view and input the Hangul phoneme on a touch screen, etc. and configuring a phoneme set for each key (S100); Outputting each key region and its elements to a proper position of the key region (S110); A touch signal input step (S120) of processing a signal input by a user with a finger or an electronic pen; Extracting a key region where the user starts a touch (S130); Analyzing a direction, a distance, a trajectory, etc. of a touch point moved in a touched state in order to determine a user's intention of selecting a phoneme (S140); Selecting a phoneme set belonging to a key where a touch is started (S150); A phoneme selection step (S160) of selecting a phoneme to be input within the selected phoneme set according to the direction angle of the touch locus obtained through the touch locus analysis; If necessary as a combination of the selected phonemes or phoneme base type, first, a combination of the base type vowels is formed to form a vowel (S170), and then, a step of forming a Korean letter to form a Korean character (S180).

According to the present invention, when inputting Korean characters using a touch screen or the like, Korean characters can be input easily and quickly using a small number of keys. Consonants can be entered with a single touch and movement, and vowels can be entered with up to three touches and movements, even a double vowel. When the Korean language is input using the present invention, it is not suitable for using a two-handed keyboard, and thus, the Korean language can be input more efficiently than conventional input methods based on when the Korean language is input using a small number of keys. The Hangul input key proposed in the present invention can be easily adapted and used by the user because the arrangement of consonants is concise and the vowel is easily understood when used.

In addition, since the Hangul input keys can be configured using only six keys, the length of each input key can be designed large for easy use by people with large hands or with low vision. You can reduce the area so that your application uses more space.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.

Throughout the specification, when a part is said to "include" a certain component, it means that it can further include other components, without excluding other components unless specifically stated otherwise. In addition, "~ unit" 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.

Hereinafter, a Hangul input system and method according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a structural diagram of a Hangul input system according to an embodiment of the present invention.

As shown in FIG. 1, the Hangul input system 100 includes a key area setting unit 200, a touch signal input unit 300, a phoneme selection unit 400, and a Hangul character composition unit 500. Here, the Hangul input system 100 may be implemented in a device that requires Hangul input such as various types of terminals including a mobile phone and a PDA and a computer.

The key region setting unit 200 sets an area of an input key input by a user, configures a phoneme set for each input key (210), and outputs each phoneme to an appropriate position of the key area (220). . The reason for configuring the phoneme set for each key is to connect more than one phoneme to one key because the number of phonemes to input is large compared to the number of keys to be used for input. For example, in FIG. 9, the set of phonemes assigned to each key is {a, ㅋ, ㄹ, ㄲ}, {c, ㅌ,, ㄸ}, {ㅂ, ,, ㅎ, ㅃ}, {ㅅ, ㅁ, ㅇ, ㅆ}, {,, ,, ㅡ, ㅉ}, {ㅓ, ,, ㅗ, ㅜ, ㅏ}. The representative phoneme in each phoneme set is the phoneme displayed in the middle of the key area and is selected when the user simply touches the key and ends the touch without moving. In FIG. 9, a, c, k, k, k, and l are representative phonemes in a phoneme set belonging to each key. Phonemes belonging to each phoneme set share one key in that the same key must be touched in order to enter any of the phonemes belonging to the same phoneme set, eg {a, ㅋ, ㄹ, ㄲ}. Can be.

The area of the input key may be defined and used by a method such as defining a zone for each key as shown in FIGS. 9 to 13 or dividing an input area as shown in FIG. 14. Information on the set of phonemes that can be input in each key area can be selectively displayed around the key area, and the displayed position is displayed in a proper form at an appropriate location according to how the phoneme can be input. For example, the input keys of FIG. 6 each have {a, ㅋ, ㄹ, ㅅ}, {ㅅ, ㅁ, ㅇ, ㅆ} as input characters. Among them, the phoneme to be selected when the key is simply touched is displayed at the center, and the phoneme to be selected is displayed at the bottom left when the user moves down the left in the touch state, and the phoneme to be selected when it is moved down the right is displayed at the bottom right. Characters or commands that do not need help to be entered by the user may not be displayed separately in the key area. That is, it is not necessary to display all the phoneme sets in the key area. The left figure of FIG. 6 shows the phoneme displayed in the area of the input key, and the right figure shows what the phoneme is actually input in accordance with the touch and movement. In the upper key of FIG. 6, when the finger is removed without movement after the touch, 'a' is selected, and when the user moves to the lower left in the touch state, 'ㅋ' is selected. If it moves upwards, 'ㄲ' is selected. 'ㄲ' does not need to be displayed separately in the input key area because it can be easily recognized by the user by defining that the user should move upward when selecting the twin consonants.

The touch signal input unit 300 transmits a signal input by a user with a finger, an electronic pen, or a mouse on a touch screen, etc. to the phoneme selector 400, and stores and transmits a touch state and a trajectory moved after touch as necessary. It plays a role.

The phoneme selector 400 may include a touch start key detector 410 for selecting an input key based on a point where a touch is started, a touch trace analyzer 420 for analyzing a direction, a distance, a trajectory, and the like moved in a touched state. One of the simplest ways to analyze the touch trajectory is to calculate the touch direction angle based on the distance and direction of the start and end points of the touch and to generate a direction code based on this, or to map the direction angle to the quantized section for each key area. The calculated direction angle or direction code among the phoneme set selector 440 of the start key region for obtaining a phoneme set belonging to the key selected by the code determiner 430, the touch start key detector 410, and the phoneme of the selected phoneme set And a phoneme selector 450 using the input direction code to finally determine the phoneme to be input. Of course, the present invention is not limited to the method described herein, since the present invention may be implemented differently from the order described herein, and some steps may be omitted if necessary, and the foregoing description merely illustrates the phoneme in each key area according to the input touch trajectory. One example to choose is.

The Hangul character composition unit 500 plays a role of forming the Hangul characters by combining the basic type of the phonemes or phonemes selected in the previous step. In the case of consonants, all phonemes except for the consonant can be selected at a time in the key area. In this way, the vowel input through the basic form requires a vowel composition unit 510 for combining the basic vowel or the vowel base type that is continuously input for input of the vowel vowel to form a neutral vowel of the Hangul.

The basic form of vowel consists of 6 vowels such as 'ㅏ', 'ㅓ', 'ㅗ', 'TT', 'ㅡ', 'ㅣ'. The rule for generating all the vowels in Korean by the combination of these basic types is shown in FIG. 15. In this way, if the vowel is input in six basic types, the number of keys for vowel input can be configured to two or less. FIG. 7 illustrates five examples in which a vowel input key is composed of two keys using a vowel basic type, and one example in which an input key is configured using three basic types of 'ㅡ', 'ㅣ', and '.'. 8 illustrates an input method of a vowel key. In order to input 'ㅓ' among the vowel basic types in the left key of the first figure of FIG. 8, as shown in the first right figure of FIG. 8, the touch is slightly moved to the left in the touch state and the touch ends. If you choose 'ㅗ', you can move upward slightly after touching and end the touch. Each segment divided diagonally in the figure represents an imaginary angular segment that can be moved to select the corresponding key. In this way, the user may select a phoneme by moving a touch within a predefined angle section. Of course, it is not possible to select the phoneme in the corresponding direction with fine movement, and the corresponding phoneme can be selected only when a constraint such as moving above a predetermined threshold value or leaving the key area is satisfied. In addition, if the distance traveled is greater than the predefined maximum, it can be recognized as a choice of another character or command. The range of the direction angles allowed to select each phoneme is predefined as shown in FIG. 8 and may be determined for each key area. To input 'ㅑ' using the first key of FIG. 8, touch and move to the right, and then touch the same key again and move to the right. If you input vowels using 6 basic types, you can input vowels on average with fewer touches than the existing methods designed for entering Korean characters on mobile phones. There is an advantage. Of course, the consonant can be input with only one touch and movement, so it can be input with fewer touches than the conventional method. Of course, you can increase the basic form to reduce the number of touches on the vowel. This case can be understood even if it is not described separately, so description is omitted here. There is no limit to the number of basic types, so increasing the basic type can reduce the average number of touches, but this increases the number of input keys, which not only takes up a wider area, but also requires more time for the user to select a key to enter. It shall be designed considering.

The Hangul alphabet composition unit 520 generates a Hangul character by combining the vowels completed by the vowel composition unit 510 and the input consonants. The input order of the Hangul should be made in the order of initial, neutral, and final, and the Hangul Jamo Composition 520 converts the Jamo input in this order into letters using the Hangul automata. The key area for the Hangul input may be variously designed as shown in FIGS. 9 to 13. 9 and 10 design a Korean keyboard using six keys, and FIGS. 11, 12, and 13 design a Korean keyboard using seven keys. Each keyboard is designed to know the input method of each phoneme by setting the phoneme set for each key and placing the phoneme in the proper position in the key area.

When inputting Hangul using the present invention, an automata for processing Hangul alphabet input can be configured in a method of determining the input without ambiguity. In other words, it is possible to eliminate the shortcomings of the existing method of ambiguity of input, such as having to wait for a while or pressing another key when inputting a phoneme on the same key in the process of continuously inputting the phoneme. For example, in the conventional method, if one key is to be inputted by "a" and "b", one phoneme is selected according to the number of touches. If the last letter of the first letter is 'a' and the first letter of the next letter is 'b', the key must be pressed once to enter the first letter and the same key must be pressed twice to enter the first letter of the next letter. The order of input is not different from the order of key input when the last letter is 'b' and the first letter is 'b'. In both cases, the same key is pressed three times, with no other key in between. To resolve this ambiguity, you must press a key or wait for a while to indicate the end of the previous keystroke selection between keystrokes. In contrast, in the present invention, there is no ambiguity in the input because the terminal sound or the double consonant in all the initial and the final sound is determined by only one input and the vowel is also determined by a combination of a series of basic types. Due to the fact that there is a double consonant in the final consonant, there is an ambiguity in the interpretation of the input in the middle of the continuous consonant input. However, this problem can be determined by a well-known simple Hangul automata that processes the existing consonants. If three consonants are contiguous and the vowel follows, the first two are double consonants, the two consonants are contiguous, and the vowels are followed, the two consonants are the last and first consonants. This is because it can be interpreted as input. Therefore, the number of touches is small during each phoneme input, and there is no ambiguity of key decision generated while inputting, thereby reducing erroneous input, and there is no unnecessary input delay or inconvenience of additional key input, so that Korean characters can be input efficiently. It becomes possible.
