The present invention relates to an alphabet input device and a method of a digital terminal provided with an input means and a direction key portion of the 3x3 grid type or more, and more particularly, a 3x3 grid type regular keyboard portion and a direction key portion in which 26 letters of the alphabet are allocated in eight sets. However, the input rule in the regular keyboard part and the input rule in the direction key part are configured to be the same, so that the basic type can input the alphabet only in the regular keyboard part, and the linkage that can input the alphabet simultaneously in the regular keyboard part and the direction key part. It relates to an alphabet input system that provides a type.

In general, a small terminal character input means usually includes a 3x4 type 12 key type keyboard portion including two special keys (*, #), and has generally inputted characters through such a normally provided keyboard portion. Devices which did not have a character input means until recently, or did not need to have a character, have also tended to have a character information processing function in such devices. Only one type of 12-key input method is applied to all types of terminals.

Among various terminals released in recent years, digital cameras, camcorders, and MP3 players are equipped with character input functions. Even if character input is not the main function, the conventional 12-key type regular keyboard input method should be applied as it is. There was an absurd point.

Mobile phones are released these days, most of the function type is exposed to the outside of the folder type, in order to enter the characters in the folder type terminal, there was a problem that you must open the folder only through the keyboard unit that is normally provided.

The present invention has been invented in view of the above-described conventional problems. In the conventional character input method, the direction key part is merely used as a direction key or a offset function, but in the present invention, the character can be input even in this direction key part. The character input system further improves user convenience by further including a basic type that can input characters only in the regular keyboard part and an interlocking type that interlocks a direction key part that applies the same input rule as the regular keyboard part according to the user's typing environment or taste. To provide.

In order to achieve the above object, an alphanumeric input device based on an advance input method of a keyboard central key, and a method thereof include a group of 26 alphabets, including a set of eight alphabets {ABC, DEF, GHI, JKL, MNO, PQRS, TUV, WXYZ} and assigned to the 3x3 grid alphabet allocation, and the ninth precombination key is further placed in the center of the 3x3 grid type, the eighth alphabet is assigned, 3x3 grid of the regular keyboard portion It is transferred to the eight-way key portion or the four-way key portion so that both are interlocked. At this time, the regular keyboard portion and the direction key portion are executed with their input rules shared.

The regular keyboard input method and the direction key input method may be interlocked into one to input characters at the same time from two input units, or in the case where such interlocking form is not necessary, only one of the two methods may be selected. A translation key is involved to make the round trip.

Among the terms used in the following description, 'arrangement / array' refers to a state in which characters are printed on the buttons of the keyboard to be visible, and 'array' means buttons due to spatial limitations such as small keyboards. The assignment of a nonprinting character to a basic placeholder with close morphological phonetic correlation with him.

Hereinafter, a preferred embodiment of a character input device and a method thereof based on a central key preceding input principle according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a configuration diagram schematically showing a character input system according to the present invention.

The character input system shown in FIG. 1 is provided with a control means 31 including an input means 10 in the form of a telephone and a font and a text table 32, and may further include a display means 20. Herein, the term “phone type keyboard” refers to a form in which 10 numeric keys and two (*, #) special keys are provided regularly, and are not necessarily limited to the telephone keyboard type. Accordingly, the character input device in the form of a telephone keypad according to the present invention is a concept including general telephones, portable communication terminal devices, information processing terminals, various remote controllers, and the like. Applicable to

Character input unit 10 shown in Figure 1 is a 3x4 type keyboard consisting of ten number buttons (1 to 9, 0) and special function keys (*, #) normally provided on the keyboard, eight numbers provided on the keyboard Only the buttons are arranged / assigned to implement the present invention, and the central precombination key acts as a precombiner of the numeric key pressed next to the numeric key.

The display unit 20 is a device capable of displaying an input character or graphic such as an LCD, and the like is outputted and displayed every time an alphabet is input so that a user inputs an input character correctly.

In addition, the control unit 31 is configured to check a signal input from the character input unit 10 and to control the output of the corresponding alphabet in the font and character table according to a predefined rule.

Figure 2a is a view showing a form in which the 3x3 lattice type character arrangement and the eight-way key portion interlocked with the alphabet is arranged on each numeric key of the telephone keyboard type that is the input unit 10 of the character input system according to the present invention.

As shown on the left side of FIG. 2A, the format including a direction key portion that simply indicates four directions in the 3x3 grid-type alphabet assignment becomes a basic type, and as shown on the right side, the 3x3 grid type and the same letter assignment format The eight-way key with the input consists of a shared input rule with the basic form, so that both become fully interlocked in form and content.

In assigning the alphabet to the input unit 10, as shown in FIG. 2A, the alphabet 26 characters are divided into eight sets {ABC, DEF, GHI, JKL, MNO, PQRS, TUV, WXYZ} and assigned to the 3x3 grid At the very center of the government, place the ninth precombination key,

ABC on top left, DEF on top center, GHI on top right,

JKL to the left of the suspension, * shape to the middle of the suspension, MNO to the right of the suspension,

PQRS on the bottom left, TUV on the bottom center, and WXYZ on the bottom right.

In addition, the eight-way key that is interlocked with the 3x3 grid alphabet allocation is assigned not only 26 alphabets divided into 8 sets in the same format and order as the 3x3 grid character allocation, but also the input rules are shared by both.

Therefore, although the character input system implemented from the present invention may be modified to the extent that the positions of the alphabets arranged on the same key are interchangeable with each other, the character arrangement pursued by the present invention is provided if the character arrangement principle is followed. The practical and effective features of the method will never be modified.

Figure 2b is a diagram showing the input rule of the 3x3 grid character arrangement and the eight-way key portion according to the present invention, showing that the input rules of both the basic type and the interlocking type is completely the same.

As shown in FIG. 2B, eight first rankers out of 26 alphabets assigned to the 3x3 grid letter arrangement in eight {ABC, DEF, GHI, JKL, MNO, PQRS, TUV, WXYZ} {A, D, G , J, M, P, T, W} are inputted by pressing the corresponding key once, and 8 second rankers {B, E, H, K, N, Q, U, X} have the central key once After the previous input, the keys arranged with the second ranker are pressed in order, and eight third rankers {C, F, I, L, O, R, V, Y} are inputted after two consecutive keystrokes. The keys arranged with the third ranker are pressed in order, and the two fourth rankers {S, Z} are inputted after the central key is input three times in succession and the keys with the fourth ranker are pressed in turn.

Figure 3a is a view showing a configuration consisting of a four-way key portion and the 3x3 grid-type character assignment in which the alphabet is divided into eight sets to each numeric key of the telephone keyboard type that is the input unit 10 of the character input system according to the present invention.

As shown on the left side of FIG. 3A, the format including a direction key portion simply indicating four directions in the 3x3 grid type input unit becomes a basic type, and as shown on the right side, an input composed of a 3x3 grid type and the same character assignment format as shown on the right side thereof. The four-way key part with the part shares the concept of the input rule with the basic type so that both become linked in form.

The interlocking four-way key portion shown on the right side of FIG. 3A lacks four directions compared to the eight-way key portion. Therefore, since the characters are not arranged in the insufficient four directions, the characters are regarded as assigned in the same form as the eight-way key portion in the insufficient four directions. In this way, the four-way key portion is assigned a character in the same format as the eight-way key portion.

FIG. 3B is a diagram illustrating input rules of the 3x3 lattice type character arrangement and the four-way key according to the present invention, showing that the input rules of both the basic type and the interlocking type are the same in principle.

As shown in FIG. 3B, in the state in which the 3x3 lattice type letter assignment unit and the four-way key unit are interlocked, in inputting 26 alphabets {ABC, DEF, GHI, JKL, MNO, PQRS, TUV, WXYZ}, the direction key unit The four first rankers printed or assigned {D, J, M, T} are inputted by pressing the corresponding key twice in succession, and the second four rankers {E, K, N, U} have one center key. After the previous input, key buttons printed with the second ranker are pressed in order, and four third rankers {F, L, O, V} are key buttons printed with the third ranker after the middle key is inputted twice. This is generated in turn by pressing.

The letter not printed on the 4-way key is A when the up key and the left key are pressed in turn, B when the center key, up key, and left key are pressed in turn, and C when the center key is pressed twice, the up key, and the left key are pressed in turn. Is entered, G is pressed when the up key and the right key are pressed in turn, H is pressed when the center key-up key-right key is pressed in turn, and I is entered when the center key twice-up key-right key is pressed in turn. When the left key is pressed in turn, P is pressed, then the center key, down key, and left key are pressed in order, Q is pressed, and when the center key is pressed twice, the down key is pressed, then the left key is pressed in order, R is pressed, and the middle key is pressed three times, down key is turned. When pressed, S is input, when down key and right key are pressed in sequence, W is pressed, center key-down key-right key is pressed in turn, X is pressed, center key twice-down key-right key in turn, Y is pressed, center key 3 When the down-down key-right key is pressed in turn, Z is input.

4 is a view showing a state in which the alphabet is arranged / assigned to the four-way key independent type according to the present invention, which is assumed that the four-way key format is executed separately, that is, not a linkage, regardless of the basic type, The assignment form and input rules of the alphabet are exactly the same as in the linked four-way key.

As described above in detail, an alphabet input device and a method of interlocking a normal keyboard part and a direction key part provided in a terminal include a basic type capable of inputting characters only in a regular keyboard part, and a direction key according to a user's typing environment or taste. The user's convenience is enhanced by selecting any one of the interlocking types that can input characters. Also, when the user selects the interlocking type among these two formats and inputs the characters, the terminal is normally provided with the terminal. Even without the keyboard part opened, characters can be input using only the direction keys exposed to the outside.
