Description

Method for inputting characters}

The present invention relates to a character input method and to inputting a character in a sliding manner with respect to a character input button.

When inputting Hangul in a mobile, PDA, PC, etc., a user generally inputs through a computer keyboard or a mobile keypad.

In the case of inputting Hangul in a mobile or PDA, a separate keypad is normally used, or in the case of a touch mobile, the Hangul input key displayed on the display is touched with a finger or a stylus pen to input Hangul.

For example, when inputting through a PC keyboard, a consonant is arranged on the left side of the keyboard and a vowel is placed on the right side so that the consonant is input by the left hand and the vowel is input by the right hand. In the case of a mobile or PDA, a vowel button is placed on one side of the mobile keypad and a consonant button is placed on the other side to enable word entry.

In the case of a PC, a separate keyboard can be used to input words using both hands.However, in the case of a mobile or a PDA, only a two-finger thumb or black can be used to find and enter a limited keyboard on a keypad. It is inconvenient to hold the stylus pen and input the Hangul consonants separately through the limited size keyboard. In other words, the consonant button and the vowel button to select the consonants to create a word while making a word, not only takes a lot of input time but also the difficulty is further increased. In particular, a user who does not correctly memorize the positions of the consonant button and the vowel button has a problem in that it takes a very long time for text input.

The present invention has been proposed to solve the above problems, and an object of the present invention is to provide a character input method configured to input characters more conveniently and quickly by only pushing one button.

The present invention includes accumulating and recognizing a movement of a text input button provided with at least one; Mapping a character to the cumulatively recognized movement; And displaying the corresponding character on a character display window.

In addition, the movement is characterized in that the sliding in the predetermined direction of the character input button.

In addition, the movement may correspond to different characters according to the magnitude of the pressure in the same direction of the slide in the predetermined direction of the character input button.

In addition, the predetermined movement is characterized by including the push and the push of the character.

The selected character may be at least one of a Korean consonant, a Korean vowel, a number, and an English alphabet.

In addition, the selected character is characterized in that it comprises a combination of a predetermined letter or a word.

In addition, the direction in which the character input button is pushed is characterized in that it is determined according to the type of the character to be input.

In addition, the correspondence of the characters to the cumulatively recognized movement may correspond to the number of movements of the character input button corresponding to the number of strokes of the character to be input.

The correspondence of the letters to the cumulatively recognized movements may be performed even if the letter input buttons are cumulatively moved in a direction corresponding to each method when at least two methods of writing arbitrary letters to be input are written. Characterized in that the arbitrary character is input.

The character input button may be implemented by one selected from a hardware device including a touch pad of a touch screen, a keyboard of a desktop, an input button of a portable terminal, a button for a mouse, a joystick, and a character input button. do.

By using the character input method according to the present invention, not only can you input syllables consisting of consonants and vowels with a single button operation but also minimize the number of button presses. .

In addition, since the user inputs with the idea of pushing the keyboard directly rather than pressing a finger on the keyboard, the user may be more interested in the keyboard input.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, in order to facilitate a person skilled in the art to easily carry out the technical idea of the present invention. do.

1 is a flowchart showing a character input method according to an embodiment of the present invention.

Referring to FIG. 1, the character input method according to the present embodiment first uses one character input button, detects a direction of a button, and inputs a character corresponding to a combination of the detected directions. The text input button has a direction sensing sensing function, and a text input button may be implemented using a touch sensor or a non-contact sensor.

In addition, the character input button is in a form that can be physically pressed, and may be implemented as a single screen on a touch screen. In addition, the character input button may be implemented in the form of a joystick, and a function for detecting the direction in which the joystick moves is required.

It is checked whether the pressing of the character input button is detected (S11). Here, the pressing of a button includes both a case where a character input mechanism starts when a hand or an input body for input is released, and a case where the character input mechanism starts after a certain pressure is applied to the button.

Subsequently, the pressing of the text input button is sensed to start the text input mechanism, and the text input button pushing direction is accumulated and recognized (S12). Subsequently, a consonant or a vowel corresponding to the pushed directions of the accumulated character input button is selected and displayed (S13).

The direction in which the letter input button is pushed is configured to detect all four directions in the up, down, left, right and four directions and the diagonal direction so that the letter input button is continuously received and accumulated in which direction. For example, when '→', '←', '↑', and '↖' are continuously input, a predetermined character is selected correspondingly. Here, the character may include all Korean consonants, Korean vowels, numbers, and alphabets.

In addition, one complete character or word corresponding to the directions of the accumulated character input button may be input.

That is, according to the present invention, when a user presses a finger or a contact means on a tactile sensor or a pressure sensor based on a finger or a contact means and continuously applies a force in a predetermined direction, the character corresponding to the directions in which the force is applied to the character display unit is applied. To make the stroke appear.

Here, the character input corresponding to the directions in which the character input button is pushed is aligned as much as the direction in which the character is written. For example, when it is detected that the letter input buttons are input in the direction of '→' and '↓', 'ㄱ' is input to the character display unit.

2 and 3 are diagrams showing direction combinations for Hangul consonants used in the character input method shown in FIG. FIG. 4 is a diagram showing a direction combination for a Korean vowel used in the character input method shown in FIG. 5 to 8 are diagrams showing direction combinations for the English alphabet used in the character input method shown in FIG. FIG. 9 is a diagram showing a direction combination with respect to numbers used in the character input method shown in FIG.

First, as illustrated in FIG. 2, when the push direction of the character input button is accumulated in the directions of '→' and '↓', 'a' is input. When it is input that the push direction of the character input button accumulates in the direction of '↓' and '→', 'b' is input.

In addition, when the jungle direction of the character input button is accumulated in the direction of '→', '↓' and '→', 'c' is input. Here '↓' may or may not be included. In addition, when the jungle direction of the character input button is accumulated in the directions of '→', '←' and '→', 'ㄹ' is input. Looking further, if the push direction of the character input button is accumulated in the direction '↓', '↓' and '→', 'ㅁ' is input.

In addition, when the push direction of the character input button is accumulated in the directions '↓', '↓', '→' and '→', 'ㅂ' is input. Here, even though the method of writing grammatically is defined in the case of 'ㅂ', the way of writing 'ㅂ' may vary depending on the person. It is possible to specify that 'ㅂ' can be entered in response to all the various ways of writing 'ㅂ'. In other words, when the direction of the character input button is accumulated in the directions '↓', '↓', '→' and '→' and '↓', '→', '↓' and '→', 'ㅂ' can be entered.

In addition, when the push direction of the character input button is accumulated in the directions of '↙' and '↘', 'ㅅ' is input.

As shown in FIG. 3, '→' and '←', '→', '↙' and '↘', '→', '→' and '↓', '→' ',' And '→' and '→', '↓', '↓' and '→' and '↓', '→', '→' and '←' When the directions are accumulated, 'ㅇ', 'ㅈ', 'ㅋ', 'ㅌ', 'ㄷ', and 'ㅎ' can be input.

Here, in the case of 'ㅌ', it is also possible to input when the push direction of the character input button is accumulated in the direction of '→', '→' and '→', or '→', '→', '↓' and It can also be input when the '→' direction is accumulated. In the former case, 'ㅌ' is input when the direction of the character input button is accumulated in three directions, and in the latter case, 'ㅌ' is input when the direction of the character input button is accumulated in four directions. In both cases, 'ㅌ' may be input.

4 shows directions of a text input button corresponding to Korean vowels. For example, 'ㅏ' is input when the character input button is pressed in the direction of '↓' and '→'.

Here, each vowel is inputted when the direction of the text input button is accumulated corresponding to the number of strokes of the Korean vowel. However, in some cases, a combination of various directions is possible.

Also, in the case of the Hangul consonants illustrated in FIGS. 2 and 3, the directions of the character input buttons may correspond to the number of strokes of the consonants.

In addition, the movement of the character input button may correspond to different characters according to the magnitude of the pressure when the character input button is pushed in the same direction. That is, even in one direction, it is to be recognized as different depending on the pressure to press the character input button.

In addition, the movement of the character input button is characterized in that it comprises the push and push of the character. That is, it is possible to implement a combination of pressing the letter input button and the accumulation of the direction, and the corresponding character is input.

5 and 8, the pushing directions of the letter input buttons may be combined, and the English alphabet may also be input corresponding to the combinations. Even in this case, each alphabet corresponds to a combination of directions as large as the direction in which the alphabet is written. In addition, in the above-described embodiment, the jungles of the eight directions are combined in the four directions and the diagonal four directions, but can be combined by detecting the jungle direction for the rotated parts. When the sliding of the character input button is detected in the same direction as '⌒', '（', or '）', the corresponding direction is accumulated and used for character input. The use of such curved movements can also be used to input Korean consonants and vowels.

Referring to FIG. 9, the push direction of one letter input button may be accumulated with respect to the number, and one number corresponding to the accumulated directions may be input.

In addition, the character input button according to the present invention may be implemented in the keyboard of the desktop, may be attached to a mobile terminal such as a mobile phone or PMP, may be implemented as a button on the mouse. In addition, the character input button may be attached to the monitor, implemented as a separate hardware, may be used by connecting to a computer or a portable terminal.

The above-described text input buttons can be implemented as various hardware structures such as simple buttons, keypads, touch pads of touch screens, joysticks, and the like, which will be briefly described below.

When a consonant button is implemented by a keypad, each consonant button in the keypad must have a hardware structure that can detect not only a push but also a push. That is, the push button structure is basically used for each character input button, but the upper side, the lower side, the left side, and the right side side can be pushed, and the side of the button must be able to detect the push through the side contact. The button structure of the push and push detection can be implemented using the "button structure for electronic products" of the Korean Patent No. 10-0829660 filed and registered by the present applicant. In other words, the button in the registered patent of the "button structure for electronic products" can be implemented to detect the pressing and push respectively.

When the consonant button is implemented using the touch pad of the touch screen, a tactile sensor method is applied to each consonant button implemented in the touch pad. The tactile sensor may detect movement in five directions of up, down, left, right, and pressing with one sensor. Such a tactile sensor may be provided in each consonant button on the touch pad to detect the push of a human finger touching each consonant button on the touch pad.

According to the Korea Research Institute of Standards and Science, the development of a touch screen using such a tactile sensor has been completed, and the direction of the jungle can be known by detecting a force distribution pressed by a human finger.

When the letter input button is implemented as a touch pad of a general touch screen, the push of the letter input button is applied to the touch pad in one push direction in a state where the contact means contacting the touch pad is fixed on the touch pad. It may be configured to be sensed by the pressure applied or the contact means in contact with the touchpad through the movement trajectory on the touchpad.

In addition, when the character input button is applied to the mouse, the technology in the fixed mouse method shown in the patent (patent number 10-0802456) filed by the present applicant may be applied.

In addition, the character input button can be manipulated by hand or by using a stylus pen or other tool.

In addition, in the above-described embodiment, the case where one character input button is used has been described. However, in some cases, two buttons or more buttons may be used.

In addition, in the above-described embodiment, the case in which the pushing directions such as the front, rear, left, and right directions of the character input button are accumulated is described as an embodiment, but other movements of the button may be used in some cases. For example, the rotational movement of the button is accumulated and recognized, and the corresponding character is displayed on the screen.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limiting the scope of the present invention. I will understand. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the scope of the appended claims, as well as the appended claims.
