The present invention relates to a wheel type text input device and a text input method, and more particularly, to a wheel type text input device and an input method for enabling text input using a wheel type input device without having a text input keypad in a portable terminal. It is about.

Recently, as the portable terminal becomes smaller and more versatile, various text input means have been implemented. The most basic character input method is to assign consonants and vowels in Korean for key buttons of "0 ~ 9", "#", "*", and to select and enter the duplicate characters by the number of pressing. In addition, the input receiving means recognizes the initial, neutral, and final characters in the program to form characters and receive them. However, the character input method is used to suggest the character assignment in consideration of the user's convenience, but basically assigning the consonants and vowels separately, the consonants are duplicated between consonants or vowels are duplicated. to be.

On the other hand, the character input method of using the following "." For the vowel input is most used. This is a method of increasing the utilization of the key by inputting the vowel in combination of only three assigned vowels "ㅣ", ".", And "ㅡ".

As another method, the keypads of "0 to 9", "#", and "*" are arranged in a 4X3 array, and a consonant or a vowel is input as if drawing with a finger in the overall configuration. It is not used much because of the disadvantage that the error rate is high.

The present invention provides a wheel type character input device and a character input method for character input in a mobile terminal such as a mobile phone, thereby improving user convenience and minimizing the size by eliminating the need for a keypad for character input. will be.

The present invention relates to a character input device of a terminal provided with a wheel-type input device configured to input key signals with a center button in the center and a quadrant button in four directions, respectively.

Allocate consonants to each quadrant of the wheel-type input device, and the number of assigned consonants is set to not more than four in one quadrant, and the allocation order of each consonant is set, and the quadrant assigned to the consonant to be inputted. Based on the order of assignment of the consonant in the quadrant, press and move the quadrant continuously from the relevant quadrant to the next quadrant according to the sequence number, and enter consonants.

It is characterized in that the vowels are inputted by a combination of the two consecutive quadrants of the left, right, top, and bottom, and the center button.

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

1 is a block diagram of a wheel type character input apparatus according to the present invention.

A wheel type input device 10 is provided in a terminal requiring a character input device. The wheel type input device 10 refers to a touch or push key input device in which an arc-shaped button arrangement is made and a button signal is distinguished for each position of four directions. Here, the wheel type input device for the present invention includes a first to fourth quadrants 11 to 14 divided into respective directions and a center button 15 in the center.

To receive the key signal from the wheel-type input device 10 as described above, a character input module 20 is required to recognize the character input, and the character input module 20 is a terminal having a wheel-type character input device. The character input module 20 may be implemented as a program in the microprocessor.

Each quadrant 11-14 of the wheel-type input device 10 is assigned a consonant not more than four to one direction button, but the order of consonants is assigned to each quadrant separately, and from the quadrant to which the consonants are assigned A consonant setting unit (21) configured to start a signal input and recognize key values for continuously inputting the next four names in the right rotation direction by the number corresponding to the order;

A key value obtained by combining the input of the center button 15 and the input of two consecutive quadrants 14, 11, 13, 12, 14, 13, 11, 12 among the quadrants of up, down, left, and right. A vowel setting unit 22 configured to recognize each vowel input;

A key input unit 23 for receiving a key signal of the wheel type input device 10;

Determining the input consonant or vowel by comparing a combination of key signals input through the key input unit 23 and key values corresponding to consonants and vowels of the consonant setting unit 21 and the vowel setting unit 22 Section 24;

The character determining unit 24 includes a character synthesizing unit 25 for displaying and outputting the characters determined according to the input and synthesizing the characters according to the Hangul combination rule.

The wheel type character input device configured as described above arranges consonants in four quadrants as shown in FIG. That is, consonants are arranged on the first to fourth buttons 11 to 14, respectively, so that the maximum number of consonants in one quadrant is not more than four.

For example, the first quadrant 11 includes "ㄱㄴㄷ", the second quadrant 12, "ㅂㅁ", the third quadrant, and "ㅅㅇㅈ", and the fourth quadrant, for example. At this time, the consonants arranged in each quadrant are also set by setting their arrangement order in the quadrant. That is, consonants are arranged in order from top to bottom in the first quadrant, from right to left in the second quadrant, from top to bottom in the third quadrant, and from sin to right in the fourth quadrant.

When the consonants are arranged as described above, information on the consonants is set in the consonant setting unit 21.

The vowel setting unit 22 sets the vowel input by reflecting the relationship between the quadrants of the top, bottom, left, and right of the wheel type input apparatus 10 and the center button in the form of the vowel.

2 is a diagram illustrating the input of consonants according to the present invention.

First, as shown in (a) of FIG. 2, when "a" is input, when the first quadrant 11 having "a" is pressed, the first of the consonants arranged in the first quadrant 11 is displayed. Judging by the input of the consonant ("a") arranged. If "b" is input, the first quadrant 11 in which "b" is arranged is shifted to a quadrant corresponding to the ordered number (second). That is, as shown in (b) of FIG. 2, when the input starts from the first quadrant 11 and moves to the second quadrant 12 and terminates the input, the "b" input is completed. In the same way, as shown in FIG. 2C, in the case of the input of "ㄹ", it starts from the first quadrant 11 and moves to the second quadrant 12, the third quadrant 13, and the fourth quadrant 14. If it is, it is recognized as "ㄹ" input. Similarly, in the case of inputting "ch" as shown in (d) of FIG. 2, if the input is moved from the third quadrant 13 to the fourth quadrant 14, the first quadrant 11, and the second quadrant 12, "Recognize it as an input.

Finally, starting from where the consonant is to be input, the first consonant in the group moves only to one quadrant per year, the second one to the next quadrant immediately adjacent to the quadrant, and the third consonant For quadrant movement, if the fourth consonant is located, move each quadrant four times to input each consonant.

The double consonants "ㄲ", "ㄸ", "ㅃ", "ㅆ" and "ㅉ" are recognized as twin consonants by simultaneously inputting the quadrant corresponding to each consonant and the center button.

For example, in the case of inputting "ㄲ", pressing the first quadrant 11 and the center button 15 to which "a" is assigned is recognized as a double consonant "ㄲ". In case of inputting "ㄸ", the sequence number (third) assigned starting from the quadrant 11 to which the terminal sound ('c') of the double consonant ('ㄸ') is assigned while pressing the center button (15) Move to quadrant (1st quadrant-> 2nd quadrant-> 3rd quadrant) corresponding to and complete the input.

Meanwhile, FIGS. 3A to 3F are vowel input explanatory diagrams using the wheel type input device according to the present invention.

The vowel input is to move two adjacent quadrants of four quadrants up, down, left and right to input 'ㅡ' and 'ㅣ', 'ㅡ' and center button, 'ㅣ' and center button Recognize vowel input by combination of.

As shown in (a) of FIG. 3, when the fourth quadrant 14 and the first quadrant 11 are moved from left to right or from right to left, input as '−', and as shown in (b) of FIG. 3, the second quadrant ( 12) and the first quadrant 11 is inputted as 'ㅣ', and all of the images moved up or down from the top or bottom are inputted as 'ㅣ'. 3 (c) shows an input of “ㅗ”, the center button 15 is first pressed, and then moved to the second quadrant 12 from the third quadrant 13, and is input as 'n'. 3 (d) shows an input of “TT”. After moving from the fourth quadrant 14 to the first quadrant 11 and pressing the center button 15, the input is 'TT'. In the same concept as above, FIG. 3E shows "ㅓ" and FIG. 3F shows "ㅏ".

On the other hand, although not shown in the figure, in the case of a double vowel, the center vowel twice by pressing the double vowel input. For example, in the case of inputting "ㅛ", when the center button 15 is pressed twice in succession and moved from the third quadrant 13 to the second quadrant 12, it is input as 'ㅛ', and "ㅠ" After moving from the fourth quadrant 14 to the first quadrant 11, pressing the center button 155 twice in a row is input as 'ㅠ'.

Here, the movement of each quadrant means that the quadrant is moved to the next quadrant while pressing the quadrant, that is, the two quadrants are subsequently pressed.

Accordingly, the key input unit 23 determines the continuity of the input signal and whether it is the next input using a predetermined time interval. In other words, the first quadrant and the second quadrant are successively pressed to input 'ㅡ', or the fourth and first quadrants are pressed respectively, the consonant 'ㅋ' and the first quadrant's consonant 'ㄱ Distinguish between 'and'. The discrimination method is determined by whether the inputs of the fourth quadrant 14 and the first quadrant 11 are within the predetermined predetermined time or independently input after being delayed for a predetermined time or more.

The distinction between the consonant input and the vowel input is to automatically discriminate the consonants or vowels inputted from the character synthesizing unit 25 by the character synthesizing rules (second, middle, and final). All of them are well known and thus are not described in the present invention.

Therefore, in the mobile terminal equipped with the wheel type input device 10, up to four consonants are assigned to each of the four quadrants 11-14 of the wheel type input device 10, and the order of allocation of the consonants in each quadrant. Set to. Consonant input starts from the quadrant to which the consonant is assigned, and when the consonant moves to the next quadrant in the same order as the sequence number assigned to the quadrant, the character input module 20 recognizes this to determine which consonant is the input consonant. And, it transmits to the display control module 30 to display the input character.

At this time, the movement of the cursor, the erasing margin, and the like use another keypad of the portable terminal. Although not shown in the drawing, it is assumed that a mobile terminal (eg, a mobile phone) has a numeric keypad or a cursor movement arrow. If not, the key setting of the wheel type input device 10 may be changed by moving the cursor or the like. And erasing functions can be set and used as direction keys. Since these settings are used in various applications, they will not be described in the present invention. However, in the present invention, there is a point in that a character, that is, inputting consonants and vowels of Korean characters in the same manner as in the embodiment.

In addition, the special characters can be input by selecting and inputting the special characters displayed on the screen by moving the cursor using menu selection. In addition, the English alphabet or numbers may be set by applying the above key input method.

As described in detail above, in the present invention, in a mobile terminal having a wheel type input device, a consonant is assigned to four quadrants of the wheel type input device and the corresponding consonant is assigned to the quadrant with the consonant to be input. Consonant input is performed by moving to the next quadrant to the right as much as the assigned sequence number and inputting the vowel using a combination of the two quadrants of the center button and up, down, left, and right, so that Korean characters can be input without using many keys. It can be a character input device. In addition, since the consonants are easily inputted with the assigned consonants and the vowels are inputted in combination similar to writing letters directly, character input is more easily and efficiently used.
