Description

{Hangul Input Method with Touch screen}

The present invention relates to a character input method for efficiently and conveniently inputting Hangul characters in an electronic device using a touch screen. More particularly, the present invention relates to a method of inputting Hangul characters It is possible to perform a simple, quick and intuitive input without switching the touch direction and the sliding direction of the touch screen by making it possible to efficiently input consonants and vowels in combination.

The use of a touch-screen character input keypad has rapidly expanded in mobile phones and tablet PCs. Although the Hangul input method of such an electronic device has been implemented in various ways such as a quadrature input method, a QWERTY method, and a double QWERTY method, most of the methods require input of consonants and vowels separately, so that if the keypad is coarse and the two hands are not used, And because all the consonants and vowels must be combined with each other, the possibility of typos is high and the input speed is restricted as the number of hands increases. In addition, existing methods of combining consonants and vowels using touch and sliding are complicated in the pattern of sliding and should be performed to change the direction of sliding one or more times. In fact, It is more inconvenient to users than touching touch screen several times to combine, increases possibility of typos and is not effective.

Accordingly, an object of the present invention is to improve a method of inputting Korean characters on an existing touch screen by combining consonants and vowels with intuitive sliding without requiring a single touch and direction switching, and propose a new Korean input method.

A method of inputting a Hangul keypad for a touch screen that displays a plurality of Hangul consonant keys on a screen and detects a touched key and inputs the sensed keys to a screen, the method comprising: sensing a touch of a specific consonant key; Activating an auxiliary vowel region around a touched consonant key; Detecting that a user is sliding in a direction or an area specified in the present invention in a state where the specific key is touched; And inputting Hangul which is a combination of a consonant or a consonant and a vowel considering the starting point of the touch and the ending position of the sliding at the end of the sliding.

According to the present invention, in inputting a character in which a Korean consonant and a vowel are combined, it is possible to input the input with a sliding method that does not require a single touch and direction switching, thereby increasing the efficiency of Korean input and excluding a vowel in a limited screen size The keypad can be efficiently arranged on the screen. Also, since the vowel is arranged around the consonant so that it can be intuitively slid according to the shape of the Hangul vowel in comparison with the existing sliding type Hangul input method, the sliding direction is set so that the user can easily and quickly input without confusion. Particularly, other conventional sliding methods include a complicated sliding input method in which sliding direction switching must be performed more than once to cause inconvenience. On the other hand, since the present invention does not need to change the sliding direction, Significantly improved efficiency and input speed can be achieved.

The terminal referred to in the present invention includes all electronic devices such as a mobile communication terminal, a tablet PC, and a computer capable of inputting characters and the like on a touch screen basis. Also, the keypad may have two or more keys (keyboard) on the terminal screen for inputting characters or the like by directly touching the screen, and may exist in a virtual keypad mode selectively displayed on the screen as needed. Sliding of a specific key means dragging in a certain direction while touching a specific key.

 1 is a block diagram showing a schematic configuration of a terminal to which a Korean-language keypad for a touch screen is applied. Referring to FIG. 1, a terminal according to an embodiment of the present invention may include a screen unit 1, a storage unit 4, and a control unit 5. The screen unit 1 may include a display unit 3 and a keypad 2 that is input by a screen touch method. The display unit 3 displays various kinds of menus of the terminal as well as information input by the user or information provided to the user. Characters corresponding to the touch of the keypad 2 are displayed on the display unit 3. In particular, the keypad 2 may exist in a virtual keypad manner, which occurs for character input as required in the display unit 3. [

The screen unit 1 has a function of detecting a touch occurring on a surface and a function of detecting coordinates of a region where a touch occurs, that is, a position value. This screen unit 1 can be operated by a resistive film type or a capacitive type. In particular, the screen unit 1 according to the embodiment of the present invention senses a touch signal input by a user and transmits a signal regarding a touched position to the controller 5. Also, the screen unit 1 senses the sliding movement and can transmit the corresponding signal to the control unit 5.

 The storage unit 4 stores user data and the like, as well as programs necessary for functioning. The storage unit 4 may include a program area and a data area. The program area stores a program for controlling the overall operation of the terminal, an operating system (OS) for booting the terminal, and an application program for performing various functions. The data area may store data generated according to use of the terminal. In particular, the data area according to the embodiment of the present invention can store the touch, the sliding movement direction, the sliding pattern, and the touch end position that occur in the screen unit 1.

 The controller 5 controls the overall operation of the terminal and the signal flow between the internal blocks of the terminal, and may include a data processing function and the like. Particularly, the control unit 5 according to the embodiment of the present invention confirms a corresponding character or moves a cursor according to a touch signal inputted to the keypad 2, and detects a touch, a sliding movement direction, a sliding pattern, And the start and end positions of the start point and the end point of the start point.

The control unit 5 can selectively control the keypad 2 to be displayed on the display unit 3 in a character input mode in which a character input program, an application, or the like is executed.

Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings.

 FIG. 2 is a diagram illustrating a reason why a user can understand a pattern of vowel arrangement around a consonant without having to learn it several times. To help understand the drawing, area lines are drawn using solid lines and dotted lines around consonants and vowels, but area lines such as circles and line lines can be used or blurred or hidden areas can be implemented can do. In Fig. 2, the auxiliary line in the vertical direction is referred to as 'ㅣ' in the Korean language bar, and the auxiliary line in the horizontal direction represents 'ㅡ' in the Korean language bar. If you look at how to combine 'consonant' with consonant, you touch the 'a' consonant and slide to the right through 'び' line of 'ㄱ'. This selects 'ㄱ' It is easy to recognize that it is similar to the shape of 'a' that draws a right stroke on 'ㅣ'. In addition, one of the strokes protruding to the right is also one of the reasons that the user can easily combine the vowel without confusion in the direction. Similarly, 'a', 'ㅗ', and 'ㅜ' can be found in the direction of a protruding stroke, passing through an auxiliary line similar to 'ㅡ' or 'ㅣ' and naturally finding a way to combine the vowel desired by the user. In addition, considering the directionality of the auxiliary line and the protruding part, 'ㅝ', which is a combination of 'ㅗ' and 'a' and '' ' Can be recognized.

 FIG. 3 is a perspective view of a first embodiment of the present invention. FIG. 3 is a partial perspective view of the first embodiment of the present invention. FIG. Referring to the right picture of FIG. 3, a vowel region having a 'ㅗ', 't', 'ㅓ' and 'a' is assigned to the upper, lower, left, and right regions around the consonant, ',' '', 'ㅕ' and 'ㅑ' are assigned to the vowel regions. In addition, a vowel region with 'ㅘ' and 'ㅝ' assigned to the upper right and lower left is formed. Once again, if you look at the vowel region according to the direction, 'a' in the right 1 st stage, 'ㅑ' in the right 2 st stage, 'ㅓ' in the left 1 st stage, 'ㅕ' In the first stage, 'ㅗ', in the upper two stages 'ㅛ', in the lower stage 1 't', in the lower stage 2 'ㅠ', in the upper right section 'ㅘ' Is assigned to each vowel region for association with consonants. Referring to the left side of FIG. 3, arrows indicate sliding patterns required for inputting only specific consonants, 'a' input, and 'ㅘ', respectively. In the case of the method of inputting only consonants, although it is expressed as sliding in the area, it can be inputted by simple touch without sliding in the consonant area. In particular, in the case of 'ㅘ', whether or not the end position of the sliding is within the area indicating 'ㅘ' is determined regardless of the area passing through the middle. Referring to the right side of FIG. 3, arrows indicate sliding patterns required for the input of 'a' and the input of ''. When sliding is completed in the first stage region, which is a region relatively close to a specific consonant, 'a', 'ㅓ', 'ㅗ' and 'ㅜ' having relatively few strokes are input. When sliding is finished in the area, 'ㅑ', 'ㅕ', 'ㅛ', and 'ㅠ', which have a relatively large number of strokes, are input. In summary, when a consonant is touched or sliding within a range set as a consonant area, only pure consonants with no vowel are input, and when starting from a consonant area and sliding to a specific vowel area, Hangul can be entered in a way that is combined with a specific vowel of the terminated area.

 4 is an embodiment of a method of inputting 'I' in the vowel input method of claim 2. In the figure, the space part without the consonant indication of the rectangular shape inside the dotted line is the start area of each vowel input. The shape and size of the vowel input start area can be changed to circular or polygonal, or by blurring or hiding the horizontal and vertical auxiliary lines. Also, the number of vowel input start regions for recognizing a touch for inputting a vowel can be increased or decreased, and can be represented as a blank on the keypad as in the embodiment of Fig. Can be input through sliding up or down from the start area of the vowel input. The arrangement of the consonants is also not limited to the embodiment.

 FIG. 5 shows an embodiment of a method of inputting '-' in the vowel input method of claim 2. In the figure, the space part without the consonant indication of the rectangular shape inside the dotted line is the start area of each vowel input. The shape and size of the vowel input start area can be changed to circular or polygonal, or by blurring or hiding the horizontal and vertical auxiliary lines. Also, the number of vowel input start areas for recognizing a touch for inputting a vowel can be increased or decreased, and can be represented as a blank on the keypad as in the embodiment of FIG. Can be input from the start area of the vowel input by sliding to the left or right. The arrangement of the consonants is also not limited to the embodiment.

 Fig. 6 is an embodiment of claim 2. Fig. The shape, size, and position of the individual consonants shown in the figure are one embodiment, and the arrangement of regions for consonants and vowels is not limited to this embodiment. 6 is an area for recognizing the start of vowel input. FIG. 6 shows one example of the input for inputting 'Hello' through touching and sliding through sequential processes (601) to (608) It is an illustration that shows. In FIG. 6, reference numeral 601 denotes a slide for inputting 'ah'. (602) is a sliding in the touch or consonant region that combines '?' (603) is a slide for inputting 'woman'. (604) is a sliding in the touch or consonant region where 'ㅇ' is combined with the input 'woman'. (605) is a sliding input for inputting a 'low'. (606) is a sliding operation in which the user first enters 'West' to input 'three'. (607) is a sliding operation for inputting '?' In order to combine the vowel '?' (608) is a sliding input for inputting 'yo'. It is possible to input all Hangul sentences in which a consonant and a vowel are combined by sliding a straight line which does not require a small number of touches and direction switching as in this embodiment. Also, as shown in FIG. 6, a plurality of start areas of the vowel input indicated by spaces in the keypad can be arranged to increase the efficiency of vowel input.

The present invention has been described in detail with reference to the preferred embodiments thereof.
