Character input device for touch screen

The present invention relates to a character input device for a touch screen, and in particular, a partial area of the touch screen is divided into a plurality of blocks in order to reduce the movement path of the touch pen and the user's gaze movement during character input, and each consonant By selectively assigning a consonant cell for generating a signal and a vowel cell for generating a Korean vowel signal, the corresponding character may be input according to the operation of the touch pen, and the touch unit is divided into a block group having at least one partitioned area. And forming an extended block on the panel which is extended to an area larger than the existing area according to the operation of the touch pen of the block, and assigning a cell having a predetermined area for generating a text signal in the extended block. The present invention relates to a character input device for a touch screen configured to generate a character input signal according to a touch of a cell.

Recently, with the start of the digital mobile phone service, various methods of text input through the phone and the emergence of various information terminals necessary for sending and receiving text have been developed, and various methods for inputting text using the touch screen of the wireless PDA terminal rather than the computer keyboard have been developed. have. However, in contrast to the reduction in the size of the terminal, the need for text input continues to increase as functions are improved.

On the other hand, when Hangul is based on the unification of Hangul spelling, Choseong is a, b, c, d, ㅁ, ㅂ, ㅅ, ㅇ, ㅈ, ㅋ, ㅋ, ㅌ, ッ, ㅎ, and neutron is ㅏ, ㅑ, ㅓ, ㅕ, ㅗ, ㅛ, ㅜ, ㅠ, ㅡ, ㅣ, ㅐ, ㅒ, ㅔ, ㅖ, ㅘ, ㅙ, ㅚ, ㅝ, ㅞ, ㅟ, ㅢ, and the finality is a, b, c, d, It consists of ㅁ, ㅂ, ㅅ, ㅇ, ㅈ, ㅁ, ㅋ, ㅌ, ッ, ㅎ, ㄱㅅ, ㄴㅈ, ㅎㅎ, ㄹㄱ, ㄹㅁ, ㄹㅅ, ㄹㅌ, ㄹㅍ, ㄹㅎ, ㅂㅅ. In addition, the theoretical number of letters that can be formed theoretically by combining initial, neutral, and final is 11,172 characters, but the actual number of commonly used characters is about 2,500 characters, and in the case of commonly used completed codes or combination codes, about 1,800 to 1,900 characters. I can express Hangul. In the existing code system, when the keyboard is input, ㄲ, ㄸ, ㅃ, ㅆ, ㅉ and ㅑ, ㅕ, ㅛ, ㅠ, ㅔ, ㅖ, ㅐ, ㅒ are allotted. In order to display the Hangul as a complete Hangul using a PDA terminal, the input corresponding to each consonant and vowel in the twelve touch areas provided by the key input method of a mobile phone used in the PDA terminal.

That is, shared blocks of (X1, X2), shared blocks of (X3, X4), shared blocks of (X5, X6), shared blocks of (X7, X8), and (Y1, Y2). Section shared block, (Y3, Y4) shared block, (Y5, Y6) shared block, (Y7, Y8) shared block, (Y9, Y10) shared block, , A shared block of the (Y11, Y12) section and a shared block of the (Y13, Y14) section.

6 is a view showing a character array of the touch unit according to another embodiment of the present invention. Referring to FIG. 6, based on the description of the independent block and the shared block as described with reference to FIG. 5, the "b" character input signal is generated in the independent block of the section (X2, X3-Y2, Y3). "B" cell is allocated, and "B" cell which generates "B" character input signal is allocated to an independent block of (X2, X3-Y4, Y5) section, and an independent block of (X2, X3-Y6, Y7) section. In the independent block of the (X4, X5-Y2, Y3) section, the "D" cell generating the "D" character input signal is assigned to the "D" cell which generates the "D" character input signal. In the independent block of X4, X5-Y4, Y5), the cell "ㅁ" which generates the "ㅁ" character input signal is allocated, and in the independent block of (X4, X5-Y6, Y7), the "ㅂ" character input signal. "ㅂ" cells that generate the symbol "X" are generated, and independent blocks of the (X6, X7-Y2, Y3) section are allocated the "S" cells that generate the "\" character input signal, and (X6, X7-Y4, Y5). In the independent block of the section, "ㅇ" which generates the "ㅇ" character input signal. The cell is allocated, and the independent block of (X6, X7-Y6, Y7) is allocated the "Y" cell that generates the "\" character input signal, and the independent block of (X2, X3-Y10, Y11) is allocated. Cell "Z" which generates "Z" character input signal is assigned, and "K" cell which generates "Z" character input signal is assigned to the independent block of (X2, X3-Y12, Y13) section, (X4 In the independent block of, X5-Y10, Y11), the "ㅌ" cell generating the "ㅌ" character input signal is allocated, and the independent block of (X4, X5-Y12, Y13) is assigned the "ㅍ" character input signal. Generated "T" cells are allocated, and independent blocks in the (X6, X7-Y10, Y11) section are allocated the "ㅎ" cells that generate the "ㅎ" character input signal, and (X2, X3-Y8, Y9). In the independent block of the section, the "ㅣ" cell generating the "ㅣ" character input signal is allocated, and the independent block of the (X4, X5-Y8, Y9) section is assigned the "-" cell generating the "-" character input signal. Is assigned.

In this case, when the touch pen touches an arbitrary consonant cell or touches an empty space between the consonant cell and the shared block, the shared block formed around the independent block and the independent block is activated, and the shared block other than the activated shared block is activated. The block is configured not to be activated to exclude mutual interference between shared blocks.

The activation may be a standby state so that a character input signal can be generated by manipulation of the touch pen.

In addition, the active "b, b, c, d, d, k, k, k, k, k, k, k, k, k, h" cells and the shared blocks around them are "b, b, c, t, h". The cells are allocated to generate a vowel signal of ㅓ, ㅓ, ㅕ, ㅏ, ㅑ ", and the cells" ㅜ, TT, ㅓ, 형성 "are formed in a thin shape, and the", ㅠ, ㅕ, 셀 "cells are" ". 으로, TT, ㅓ, ㅏ "cells are formed in a thicker shape to make them easier to distinguish from each other, so that" ㅗ, ㅛ "cells are set on the upper side," TT, ㅠ "cells are set on the lower side, and" ㅓ "on the left side. , "V" cells are set, and the "v, v" cells are set on the right side.

For example, when the cell "a" is touched, the cells "ㅗ, ㅛ" are set in the upper block of the shared blocks around the cell "a", that is, in the (X1, X2-Y1, Y2) section, and the lower block, In the (X3, X4-Y2, Y3) section, the "TT, ㅠ" cell is set, and in the (X2, X3-Y1, Y2) section, the "ㅓ, ㅕ" cell is set, the right block, In the (X2, X3-Y3, Y4) section, "ㅏ, ㅑ" cells are set.

In addition, when the "b" cell is touched, the "b, ㅛ" cell is set in the upper block of the shared blocks around the "b" cell, that is, the (X1, X2-Y4, Y5) section, and the lower block, that is, (X3 In the (X2, X3-Y3, Y4) section, the "#, Y" cell is set and the right block, (X2) In the,, X3-Y5, Y6), "Y, Y" cells are set.

Herein, the right block of the "a" cell and the left block of the "b" cell become a shared block, that is, a section (X2, X3-Y3, Y4).

Therefore, when the cell is activated in the "b" cell, the cell "ㅏ, ㅑ" is set in the right block, and when activated in the cell "b", the cell "설정, ㅓ" is set in the left block.

On the other hand, the shared blocks around the " '" cells allocated to the independent blocks of the (X2, X3-Y8, Y9) sections, that is, the "ㅢ, ㅚ" cells are allocated to the upper (X1, X2-Y8, Y9) sections, The lower side, that is, the "X" cell is allocated to the (X3, X4-Y8, Y9) section.

In addition, "X, Y" cells are assigned to the upper side of the (X6, X7-Y8, Y9) section, that is, the (X7, X8-Y8, Y9) section. Are assigned to the "ㅝ, ㅞ" cell, and that is, the "X, (" cell is assigned to the left, that is, the (X6, X7-Y7, Y8) section, and to the right, the (X6, X7-Y9, Y10) section, 셀, ㅒ "cells are assigned, but" ㅘ, ㅐ, ㅝ, ㅔ "is formed in a thin shape, and" ㅙ, ㅒ, ㅞ, ㅖ "is formed in a thicker shape so that it is easier to distinguish them from each other. "ㅘ, ㅙ" cells are set, "ㅝ, ㅞ" cells are set on the lower side, "ㅔ, ㅖ" cells are set on the left side, and "ㅐ, ㅒ" cells are set on the right side.

In this way, mutual interference, movement of the user's field of view, and movement of the touch pen are minimized.

For example, in order to display the Korean character "Korea", first touch the "ㄷ" cell assigned to the independent block of the section (X2, X3-Y6, Y7), and then (X6, X7-Y9, Y10). Touch the "ㅐ" cell assigned to the shared block of the section to display the character "large" with two pen touches, and select the "ㅎ" cell assigned to the independent block of the section (X6, X7-Y10, Y11). Touch the "ㅏ" cell assigned to the block of (X6, X7-Y11, Y12) formed around it, and touch the "b" assigned to the independent block of (X2, X3-Y4, Y5). To display the letter "one" with three pen touches, touch the cell "ㅁ" assigned to an independent block of the section (X4, X5-Y4, Y5), and select the (X2, X3-Y8, Y9) section. Touch “ㅣ” cell assigned to an independent block and touch “b” cell assigned to an independent block of (X2, X3-Y4, Y5) section. Touch the "a" cell assigned to the independent block of (X2, X3-Y2, Y3) Touch the "TT" cell assigned to the formed block of (X3, X4-Y2, Y3), and touch the "A" cell allocated to the independent block of (X2, X3-Y2, Y3) again. Hangul "Kuk" is displayed with the pen touch of the conference, and Korean characters "Korea" can be displayed with a total of 11 pen touches.

In this case, the vowel except for the "ㅣ" collection needs to be pen touched in the block in order to activate the block. Therefore, it is preferable to pen touch from the inside of the block to the outside to input the vowel.

On the other hand, double-touch each of the consonant cells "a, c, ㅂ, ㅅ, ㅈ" among the consonants were set to generate a character input signal of "ㄲ, ㄸ, ㅃ, ㅆ, ㅉ".

It will be apparent that the above descriptions of FIG. 3 and FIG. 6 can be complementarily applied. In addition to the above-described text input for Korean, the input of English, Japanese, numbers, and special characters is another approach. The description is as follows.

9 is a view showing a portion of the extended block when inputting the English character according to another embodiment of the present invention. 9A and 9B illustrate that a cell generating a corresponding character input signal is allocated to an extended block, but is displayed in the shape of a figure around the block. First, referring to FIG. 9A, when the touch pen is in contact with the section (X0, X1-Y0, Y1) of FIG. 7, including the existing (X0, X1-Y0, Y1) section (A0, A4-B0) And a cell generating a character input signal of "A, B, C" is allocated, and the cells generating the character input signal are allocated to a section (A0, A1-B1, B3). A cell that generates the A " character input signal is assigned, and a cell that generates the " B " character input signal is assigned to the (A1, A3-B3, B4) section, and a " A cell for generating a C " character input signal is allocated, and an English upper / lower case conversion cell capable of converting to a letter of “a, b, c”, which is a lowercase letter of “A, B, C” of FIG. , A3-B0, B1), and generates a corresponding character input signal or an English case conversion signal according to a drag operation or touch of the touch pen to the corresponding cell.

For example, if you want to print the letter "A" on the touch screen,

First, when the (X0, X1-Y0, Y1) section is touched, the corresponding block is activated and extended to the (A0, A4-B0, B4) section to form an extended block, and (A0, A1-B1, B3). When dragging the touch pen to the cell of the section, the English letter “A” is output on the touch screen.

In addition, in the section (A1, A3-B0, B1) of FIG. 9A, an English case switchable cell capable of interchanging English capital and lowercase letters is assigned and according to (A1, A3-B0, B1) section contact of the touch pen. Initially set to the uppercase English capital letters are converted to lowercase English, it is possible to generate a signal for entering the lowercase English letters.

On the other hand, Figure 9b shows that the cell having the English upper and lower case generation signal is allocated, if the touch pen is in contact with the (X0, X1-Y0, Y1) section in Figure 7, the existing (X0, X1-Y0, Y1) cell including the (A, a), (B, b), (C, c) "and extending to the section of (A0, A4-B0, B4) The cells are allocated cells generating an "A" character input signal in the (A0, A1-B1, B2) section, and generate an "a" character input signal in the (A0, A1-B2, B3) section. Cells to be allocated are allocated, and cells (A1, A2-B3, B4) generate a "B" character input signal, and cells (A2, A3-B3, B4) generate a "b" character input signal. Cells to be allocated are allocated, and cells (A3, A4-B1, B2) generate "C" character input signals, and cells (A3, A4-B2, B3) generate "c" character input signals. Cell is assigned, and the character input signal of the corresponding character The lives.

Meanwhile, FIGS. 9C and 9D show that a cell for generating a corresponding character input signal is allocated to an extended block, and the corresponding character is directly displayed on a cell allocated to the corresponding block.

First, in FIG. 9C, when the touch pen is in contact with the section (X0, X1-Y0, Y1) of FIG. 7, including the existing (X0, X1-Y0, Y1) section (A0, A4-B0, B4) In addition to being extended to the interval of, the cells that generate the character input signal of "A, B, C" is allocated, the cells generating the character input signal is the "A" character in the (A0, A1-B1, B3) section A cell generating an input signal is assigned, and is indicated as "A", and a cell generating an "B" character input signal is assigned to the (A1, A3-B3, B4) section, and is marked as "B", ( In the sections A3, A4-B1, B3), a cell generating a "C" character input signal is allocated, and is indicated by "C", and additionally, "a, b, c", which is a lowercase letter of "A, B, C". English case conversion cells that can be converted into letters of the letter are assigned to the section (A1, A3-B0, B1), and are marked as "小", and the corresponding character input signal according to the dragging action or touch of the touch pen to the corresponding cell. Alternatively, an English case conversion signal is generated.

For example, in order to output the English character "Home"

G (block containing representative characters) + H (cell in extended block) = H

M (block containing representative characters) + case switch cell (small) = switch to lower case input mode

M (block containing representative characters) + o (cell in extended block) = o

11 is a diagram illustrating an extended block when inputting Japanese characters according to another embodiment of the present invention. Referring to FIG. 11, expansion blocks are formed at a predetermined ratio based on blocks separated by the touch unit in FIG. 10, and the intervals (X0, X1-Y0, Y1) are (A0, A4-B0). And extends to (B4) section, section (X0, X1-Y1, Y2) extends to section (A0, A4-B2, B6), and section (X0, X1-Y2, Y3) is (A0 And extends to (A0-B4, B8) section, and (X0, X1-Y3, Y4) section extends to (A0, A4-B6, B10) section, and (X0, X1-Y4, Y5) Section is formed extending to the (A0, A4-B8, B12) section, (X0, X1-Y5, Y6) section is formed extending to the (A0, A4-B10, B14) section, (X0, X1- Y6, Y7) section is extended to section (A0, A4-B12, B16), (X0, X1-Y7, Y8) section is formed extending to section (A0, A4-B14, B18), ( X0, X1-Y8, Y9) section extends to (A0, A4-B16, B20) section, and (X0, X1-Y9, Y10) section extends to (A0, A4-B18, B22) section Formed, the expansion The cells generating the input signal of the corresponding character are allocated within the block interval. Each extended block is assigned to "あ (a), い (i), う (u), え (e), お (o)", "か (ka), き (ki), く (ku), け (ke), こ (ko)", "さ (sa), し (shi), す (su), せ (se), そ ( so) "," た (ta), ち (chi), つ (tau), て (te), と (to) "," な (na), に (ni), ぬ (nu), ね (ne ), の (no) "," ha (ha), ひ (hi), ふ (fu), へ (he), ほ (ho) "," ま (ma), み (mi), む (mu) , め (me), も (mo), "や (ya), ゆ (yu), よ (yo)", "ら (ra), り (ri), る (ru), れ (re), The cells "ro" and "wa (wa), n (n) and o (o)" are allocated.

12 is a diagram illustrating a part of extended blocks when inputting Japanese characters according to another embodiment of the present invention. 12A and 12B show that a cell generating a corresponding character input signal is allocated to an extended block, but is displayed in the shape of a figure around the block.

First, referring to FIG. 12A, when the touch pen contacts the (X0, X1-Y0, Y1) section in FIG. 10, the existing (X0, X1-Y0, Y1) section includes (A0, A4). A cell which extends to the interval of B0, B4) and generates a character input signal of "あ (a), い (i), う (u), え (e), お (o)" is allocated. The cells are assigned a cell generating the "あ (a)" character input signal in the (A1, A3-B1, B3) section, and the "い (i)" character in the (A0, A1-B1, B3) section. The cell generating the signal is allocated, the cell generating the "U (u)" character input signal is assigned to the (A1, A3-B3, B4) section, and the "え" is assigned to the (A3, A4-B1, B3) section. (e) A cell generating the character input signal is assigned, and a cell generating the "O (o)" character input signal is assigned to the (A1, A3-B0, B1) section, and the touch pen is dragged to the corresponding cell. The character input signal is generated according to an operation or a touch.

For example, if you want to enter the Japanese character of "あ", as shown in Fig. 10, first touch the (X0, X1-Y0, Y1) section with a touch pen, (A0, A4-B0, B4 ), The cell that can generate Japanese characters of "あ" is assigned to the center of the expanded block, and "い, う, え, お" is assigned to the surroundings one after the other. When the drag operation to the cell around the expansion block is completed, the corresponding character input signal is generated, or when the touch pen is released from the panel as it is after the initial touch, the Japanese character of the representative character "あ" is generated. Alternatively, an extended block is formed after the initial touch of the touch pen, and the user desires to generate Japanese characters by touching the corresponding cell in the center or surrounding of the representative character while maintaining the extended block until the second touch occurs. And At the same time, when the extended block disappears, it becomes a small block on the touch screen in the form shown in FIG. This can be applied to Korean character input, English character input, numeric input or special character input as well, and can also be applied to another language type selection method.

On the other hand, Figure 12b has shown that the expansion block is formed in a different shape, it will be preferable to form the expansion block more progressively.

When the touch pen is in contact with the section (X0, X1-Y0, Y1) in FIG. 10, the expansion block is formed in a circular shape, and a predetermined cell is formed therein for generating a Japanese character input signal.

As shown in the drawing, a cell generating a text signal of "あ (a)" is assigned to a cell "1a", a cell generating a text signal of "ア (a)" is assigned to a cell "1b", and a cell of "1c" is assigned. A cell generating a text signal of "i (i)" is assigned to a cell, a cell generating a text signal of "i (i)" is assigned to a cell "1d", and a cell "u" is assigned to a cell "1e". u) a cell generating a text signal of " " is assigned, a cell generating a text signal of " w (u) " is assigned to a cell " 1f ", and a text signal of " (e) " Is generated, a cell generating a text signal of "E (e)" is assigned to a cell "1h", and a cell generating a text signal of "お (o)" is assigned to a cell "1i". The cell “1 (j)” is assigned a cell that generates a character signal of “o (o)” to generate the character input signal according to the drag operation or touch of the touch pen.
