It is about a method.

The present invention relates to a character input method using a touch screen that simplifies a method of inputting characters on a touch screen employed in an electronic device such as a mobile phone, a PMP, a MID, and the like, and enables a quick input.

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, it is urgent to provide a method designed to make inputting easier in case of inputting English as well as Korean.

Conventionally, among the character input devices displayed on the touch screen, a user presses a character that the user wants to input using a finger or a touch pen, and the electronic device recognizes the push signal as an input signal.

However, according to this method, it is time-consuming because each character must be selected and pressed individually, and because the area where the displayed characters are arranged is limited according to the screen size of the touch screen, the neighboring characters are incorrectly recognized and mistyped. There is a problem that the frequency of occurrence is very high.

In order to solve this problem, a character input method of a dragging method is introduced instead of a pressing method, but this also has a problem of selecting a consonant in Korean input by pressing a method and inputting a vowel by a dragging method. .

Therefore, there is a need for a new character input system that can improve character input speed, more conveniently input characters of other languages such as alphabets, as well as reduce typos in the input process.

In addition, the input method using the existing touch screen is inputted only by touching the screen, so that users who are not familiar with the text method using the screen can not easily touch the object with the character array. There is a demand for a way to touch a string and enter the desired character.

The present invention can significantly increase the input speed rather than inputting letters by selectively pressing individual letters arranged on the touch screen, and inputting characters by a dragging method that can drastically reduce typos in the input process. To provide a way.

In addition, the present invention is to provide a new character input method that is easy to expand to the case of inputting characters of not only Hangul but also other languages.

Characters disposed in the input object according to the touch and the drag direction of the touch is characterized in that the recognition.

In this case, the input object moves in the drag direction on the touch screen according to the drag operation after the touch, returns to the original position according to the release operation of the touch, and the character recognition means recognizes a character corresponding to the drag direction of the input object. Characterized in that.

In addition, the input object is divided into eight directions of up, down, left, right, and four diagonal directions to display a character group grouped into a plurality of characters corresponding to each direction. After the touch after the drag operation occurs, when a predetermined time elapses, the characters belonging to the character group corresponding to the drag direction are sequentially selected, and when the touch release of the input object occurs, the selected characters among the character groups Characterized in that recognize.

According to another embodiment of the present invention, a sensing unit for sensing a drag and a touch on the touch screen, and a character recognition means for displaying a character by combining the consonants and vowels by recognizing the character by the signal detected from the sensing unit A character input device may be provided, and the touch screen may display a consonant input object and a vowel input object detected by dragging and touching, and an output window for outputting a result recognized by the character recognition means. A consonant arranged around the vowel input object, and the vowel input object includes vowels arranged around the vowel input unit, and the character recognition means includes the consonant input according to the touch of the consonant input object or the vowel input object and the dragging direction of the touch. Consonants and vowels placed on an object or vowel input object are selected It characterized in that the combination.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

However, embodiments of the present invention illustrated below may be modified in various other forms, and the scope of the present invention is not limited to the embodiments described below.

Embodiments of the invention are provided to more fully illustrate the invention to those skilled in the art.

13 is a block diagram of a character input apparatus according to the present invention. The present invention is suitable for an electronic device having a touch screen. Therefore, a sensing unit 150 for detecting a drift and a touch on the touch screen and a character recognition unit 130 for recognizing and displaying a character by a signal detected by the sensing unit are included.

The character recognition unit 130 includes a function of completing a character by combining consonants and vowels in the case of Korean. However, in the case of Japanese and English, input characters are recognized as they are.

An input window 120 and an output window 140 are provided on the touch screen. Characters recognized by the character recognition means 130 is displayed on the output window 140. The control unit 110 is generally known and used to control the transmission of signals between the character recognition unit 130, the detection unit 150, the input window 120, the output window 140, etc. It will be omitted.

An input object is displayed in the input window 120. 1 to 4 illustrate an embodiment of an input object. 1 is a consonant input object used in the case of Korean input. The key point of the present invention is to drag the input object in the desired direction while touching the input object, and then release the touch operation. In addition, in the case of Hangul, it can be interpreted to include consonants or vowels) is selected and recognized by the character recognition means 130.

Therefore, a character corresponding to the direction is displayed around the input object to guide the user. The drag direction of the input object may be determined by connecting a straight line from the touch point to the release point after the drag and measuring the angle thereof. In the present specification, the drag angle means an angle of a straight line between an input point and a release point of a touch. Therefore, by dividing the angle, the drag direction corresponding to the inputtable character is determined. Since there are 14 Hangul consonants, it is possible to display and use all consonants in one input object by setting angles corresponding to each direction by dividing 360 degrees into 14 directions.

However, the larger the number of divisions, that is, the narrower the range of angles corresponding to one character, the greater the error of the input value due to user's carelessness. Therefore, the range that the user can input most conveniently is 8 directions of upward direction, downward direction, left direction, right direction, and diagonal direction of each direction, so it is preferable to set the range of the input angle based on this.

FIG. 1 is a consonant input object configured to set drag directions in eight directions and display characters recognized in each direction. The character recognition unit recognizes a character disposed in the input object according to the touch of the consonant input object and the drag direction of the touch.

2 is a diagram in which vowels are grouped and set in vowel input objects divided in eight directions by the same method.

The Hangul consonants and vowels are alternately inputted and combined to form letters, so the consonant input object and the vowel input object are preferably displayed together. 5 illustrates an embodiment in which a consonant input object and a vowel input object are displayed on the touch screen. The lower part is the input window and the upper part is divided into the output window.

Hereinafter, a method of inputting a character using the input object according to the present invention will be described in detail.

6 illustrates an embodiment of inputting a character using an input object. After the user touches the input object, the user drags the input object between the upward direction and the right direction. In this case, a value of 'b', which is set in advance in response to the input signal, is displayed on the output window of the character and is input. The value may be recognized and input while the input object is dragged, or may be recognized and input after the touch is released while the input object is dragged.

However, when the drag direction (character recognition direction) is limited to eight directions, there are some of the 14 consonants that are not included. Therefore, it may be provided to be grouped in plural in accordance with each drag direction. For example, 'ㄱ' and 'ㅋ' are grouped together.

At this time, the following method can be used to input the value of 'ㅋ'. While touching the input object, drag in the diagonal direction of the upper right. In this state, the letter 'ㄱ' is selected. However, when a signal indicating that the touch state has elapsed for a predetermined time in the dragged state is detected by the character recognition means, the recognition state is changed to the next character in the character group. Therefore, the value 'ㅋ' is selected and displayed in the output window. The present invention can be implemented in either of automatically selecting a 'k' value after a certain time and selecting 'k' value after releasing the touch after a predetermined time.

FIG. 7 illustrates a state in which the user is changed to 'ㅋ' by maintaining the touch state for a predetermined time or more in the state of 'a' of FIG. 6.

A function of displaying the currently selected character according to the drag direction may be added to the input object. In FIG. 6 and FIG. 7, the space is divided and divided so that the selected consonants can be displayed through different colors and shades.

In the embodiments of FIGS. 6 and 7, the input objects are provided to be moved together in the direction according to the drag operation. In this case, it is preferable to return to the original position when releasing the touch state after dragging.

In addition, the path along which the input object moves is preferably fixed according to a predetermined number of directions. For example, when the predetermined drag direction is 8 directions, when the input drag angle is 22.5 degrees and 67.5 degrees, the input object is recognized as being input diagonally upward and the input object is moved in the 45 degree direction. It is to let.

In addition, although the description has been given of moving the input object, this is to improve the convenience by visually delivering a value input to the user. Therefore, it is also possible to recognize and select an input value according to the drag angle without moving the input object.

Various methods may be used when inputting consonants through the character input method according to the present invention, but as an example, the dragging operation is continuously performed in the direction. That is, in order to input 'ㄲ', the same operation as inputting 'ㄱ' is performed. Then, the same operation is performed again before the predetermined time passes. The character recognition means recognizes with consonants when the same dragging operation is performed continuously. In addition, when the "chicken" is input, 'ㄹ', 'ㄱ', 'ㅇ' input operation is performed, the character recognition means, if three consonants are input consecutively consonant first two consonants It is preferable to recognize as.

8 and 9 illustrate a process of inputting the vowel 'ㅏ' and 'ㅑ' in the same manner as described above.

If the consonant input object and the vowel input object are simultaneously displayed in the input window, and the left and right hands can be input respectively, the text input speed can be doubled. The character recognition means selects consonants and vowels arranged in the consonant input object or the vowel input object according to the touch of the consonant input object or the vowel input object and the drag direction of the touch, and performs a function of combining characters.

Character input method and apparatus according to the present invention can be easily extended to the input of the alphabet. 3 and 4 illustrate one embodiment of an alphabet input object.

In the case of the alphabet, since the number of characters is large, it is convenient to use two input objects in the case of using an input object in eight directions. This is equivalent to using a consonant input object and a vowel input object at the same time.

10 is a letter of 'A' and FIG. 11 is a letter of 'Z', and the detailed description thereof will be omitted since it is the same principle as the Korean input.

12 shows a special key input object arranged between two input objects. As described above, the backspace and the return key may be selected according to the drag direction after the touch, and the input of the space may be selected according to the operation of only the touch. It is apparent that the present invention may be variously modified according to the embodiment implemented using the present invention.

14 is an illustration showing that the text input device according to the present invention may be provided vertically on the touch screen, and FIGS. 15 and 16 are examples of using the text input device according to the present invention.

The present invention can be applied to not only a text input device but also a text input method using the same.

That is, in a text input method using a touch screen for recognizing and displaying a character by a signal input from the touch screen, the input object is detected on the touch screen by dragging and touching, and the characters are arranged around the touch screen. And detecting a touch and drag direction generated in the input object, and displaying a character set corresponding to the drag direction when the touch is released from the input object.

This method is obvious that the methods mentioned in the process of describing the character input device described above may be added or modified.
