Description

Korean input device and method using touch input means {A method and aparatus for Hangul automata utilizing touch-sensitive input devices}

The present invention relates to a Hangul input device and method using a touch input by contact and proximity, and particularly to a Hangul input device and method for fast and effective input of Hangul, even in a small area of the touch screen, touch pad or tablet. It is about.

Recently, mobile phones have been rapidly equipped with a touch screen, but the method of inputting Hangul through the touch screen has not changed much.

The Korean input method commonly used in the touch screen includes a method of touching a button on a 2-Ball type keyboard drawn on the screen with a pointed tool such as a stylus, and a keyboard of a button type Korean input device (for example, Cheonji) that is drawn on the screen. The method of touching a button with a finger or a stylus is used. That is, the Hangul input methods currently mounted on the product and actually used are "pressing" the buttons displayed on the screen, which does not exceed the limits of the conventional button type Hangul input device.

Since the buttons on the 2 beol type keyboard are displayed too small on the touch screen, it is inconvenient to input Korean characters, and the conventional button type keyboard is displayed on the touch screen largely, but it is inconvenient to press too many buttons to input the Korean characters. .

If you write by hand using the handwriting recognition function, there is a method of recognizing the character of the mobile phone, but the input speed is too slow, and if the person who cannot write beautifully, the character recognition success rate is low.

The Hangul input device has been proposed to input consonants and vowels by starting the touch in the consonant area and dragging them to the vowel area using the features of the touch screen, but it is difficult to effectively input Hangul through the narrow touch screen. .

"Double input keys and data inputs including the same" (application number 10-2006-0064098) have been proposed, but this is only another way of "pressing" on-screen buttons.

A Hangul input device of an electronic device for arranging a consonant of Korean characters on a touch screen, inputting a consonant by an initial touch, and then inputting a vowel by dragging on the touch screen has been proposed. This method has the advantage of simplifying the screen by omitting the vowel arrangement on the touch screen, but the input time of the Hangul input device using the handwriting recognition function is increased because the vowel is input by dragging.

The present invention is to solve the inconvenience of the prior art, to provide a Hangul input device and method that can be quickly and conveniently input by touching and turning off the touch unit.

According to the present invention, the touch unit for providing a plurality of buttons with consonants and vowels are duplicated; A memory unit for storing consonants and vowels assigned to each button; A sensing unit which senses touch and drag applied to the touch unit by contact and proximity; In the case where the touch-started button and the touch-released button are different from each other, the method may include extracting and combining two consonants or two vowels respectively assigned to the touch-started button and the touch-released button from the memory unit. A controller; It is achieved by the Hangul input device and method comprising a; display unit for representing the process of the Hangul input is processed on the screen.

It is most preferable that one consonant and one vowel are assigned to the button. Each time the touch of the button is released, the controller alternates the types of letters to be extracted from the memory unit so that consonants and vowels assigned to the buttons can be input in one operation.

The button may include a consonant consonant. The consonant consonants a, b, c, ㅁ, ㅅ, ㅇ, ㅈ to make ㅋ, ㄷ, ㅌ, ㅂ, ㅈ, ㅎ, ㅅ.

The button may include a button instructing to make a character having a finality.

The button may include a button indicating that no consonants or vowels are used.

A plurality of consonants may be assigned to the button. The controller determines that the selection of letters is not completed when a button with a plurality of consonants assigned to the consonants is extracted from the memory unit. If the next touched button is the same button, other consonants overlapped with the corresponding buttons Presented in sequence to allow all consonants assigned to the button to be inputted, and when another button is touched, confirms the selection of the last consonant presented above, alternates the types of letters to be extracted next from the memory unit, and finally Extracts and inputs vowels from the memory unit that stores the duplicated letters in the touched button.

A plurality of vowels may be arranged on the button. The controller determines that the selection of letters is not completed when a button in which a plurality of vowels are arranged is touched in the order in which the vowels are extracted from the memory unit is judged to be incomplete. Presents them sequentially so that all the vowels that are overlaid on the button can be entered.When another button is touched, the selection of the last vowel presented above is confirmed, and the next type of letters to be extracted from the memory unit is alternated. Consonants are extracted from the memory unit storing the letters overlaid on the buttons.

The sensing unit transmits the location information where the touch is started to the controller.

The touch unit frequently transmits the position information of the drag to the controller when drag is generated after the touch.

The sensing unit transmits the touched position information to the controller.

The controller may highlight and display a button currently being touched through the display to visually indicate an input process.

If the start of the touch, the drag and the release of the touch is made on the same button, the controller extracts and inputs from the memory unit a letter type to be extracted at this time among the letters duplicated on the button. Alternate the type of characters to extract.

The control unit extracts from the memory unit a type of a character to be extracted at this time among the letters placed on the button when the touch is started and released on the same button but the drag performed between the buttons is outside the button area. And combining the two extracted letters to input a combination consonant, a combination vowel, or two identical consonants or two vowels, and alternating types of letters to be extracted next from the memory unit. This is especially effective for inputting sounds such as ㄲ, ㄸ, and emotional expressions such as ㅋㅋ, ㅎㅎ, TT TT, and ㅡ ㅡ.

The control unit extracts and combines two consonants or two vowels respectively disposed on the touch-started button and the touch-released button from the memory unit when the touch-started button and the touch-released button are different from each other. Alternatively, a combination vowel is input, and the types of letters to be extracted next from the memory section are alternated. This is particularly effective for inputting combination consonants such as ㄶ, 이나, and combination vowels such as ㅙ, ㅢ.

The controller may include alternating types of letters to be extracted next from the memory unit when a button indicating that the consonants or vowels are not used is touched and the touch is released. This is necessary to enter a letter consisting of only vowels, such as TT.

The controller generates and outputs a Hangul consisting of only the initial and the neutral, unless otherwise indicated.

The control unit may include a function of outputting a Hangul made of consonants and vowels inputted until a touch state lasts for a predetermined time on one button.

The controller is configured to extract consonants from letters that are overlapped with the currently touched button from the memory unit when the touch state lasts for more than a predetermined time in a state in which the type of the character to be extracted from the memory unit is a consonant, It may include a function for outputting Hangul as the final consonant.

The controller may include a function of outputting Hangul as the final consonant when the button for instructing completion of the character is touched while the type of the character to be extracted from the memory unit is a vowel.

The Hangul input device by means of touch input by contact and proximity according to the present invention is one touch and drag for initial input, one touch and drag for neutral input, and one touch and drag for final input. Since Hangul can be input, it is equivalent to the 2 Beolsik keyboard in terms of input efficiency.

When entering a combination consonant or a combination vowel, two buttons must be touched anyway. In the Hangul input device according to the present invention, since the two buttons need to be moved by dragging, virtually unnecessary operation does not exist, thus the efficiency is doubled. Equivalent to keyboard

However, since there are about 12 buttons required, it is possible to provide a button that is twice as wide as a 2 bee keyboard that requires 26 buttons, so a 2 bee keyboard is available for Hangul input that is performed in an environment using a small area touch input device. It is much more advantageous.

Until now, there are no Korean alphabet input devices used in small electronic devices such as mobile phones, so the Korean alphabet input device using touch and touch input by means of contact and proximity according to the present invention is conventional. It is more efficient and convenient than any Korean input device.
