Description

A process for inputting letters by using touch screen}

The present invention relates to a character input method using a touch screen, and more particularly, the start and end points of a drag as well as a click on each input cell displayed in an input window of a touch screen. Recognizing each character input signal, the character input method using a touch screen that can quickly input two unit letters, for example, two English alphabets or two Arabic numerals, or Korean kanji consisting of consonants and vowels with just one drag It is about.

Recently, as portable electronic devices such as mobile phones, PDAs, notebook computers, etc. become increasingly thin and short, input devices using touch screens are widely used. Such a touch screen has a touch pad attached to a display unit formed of a liquid crystal display (LCD), and a plurality of input cells having predetermined input information is displayed on the touch pad. When the input cell is touched with a touch pen such as a stylus, a character or a menu corresponding to the input cell is selected. In this case, the operation method of the touch pen is generally divided into a 'click' indicating one point on the touch pad and a 'drag' continuously moving from one point to another.

Conventionally, various character input devices and methods using a touch screen have been developed. For example, Korean Patent Publication No. 2005-102829 (published date; Oct. 27, 2005) introduces a Korean input device in which 14 Korean consonants, 5 vowels, and input cells corresponding to 'pairs' are displayed on a touch screen. Thus, the input cell corresponding to the beginning of the drag is selected as the initial, the neutral is selected according to the movement shape from the beginning to the end of the drag, and the added vowel or finality is down-up for the input cell. It is configured to select by operation. However, such a Hangul input device has a drawback in that the drag operation for selecting a neutral, that is, a Korean vowel is very complicated, and an English character cannot be input.

In addition, Korean Patent Registration No. 772505 (Notification date; 2007.11.01.) Starts from the blank area of the touch screen, that is, the area where the input cell is not displayed, and drags it to a letter cell in which the desired letter is displayed. Apparatus and method for inputting are introduced. However, such a method has a drawback in that it is necessary to input one unit character by one drag operation, so the input speed is slow, the arrangement of text cells is very complicated and unfamiliar, and it is unsuitable for Hangul input.

In addition, Korean Patent Registration No. 821161 (Announcement Date; 2008.04.14.) Introduces a character input method of inputting consonants at the beginning of a drag and inputting a vowel according to the direction and length of the drag. However, in this method, there is a problem that it is difficult to accurately control the length of the drag, and in particular, in order to input the lap collection, the input speed is slow because the drag must be delayed for a certain time, and the English input is also impossible.

As described above, the character input methods using the conventional touch screens have their own characteristics, but they are difficult to apply to Korean, English, and numbers in common, and there are problems such as slow input speed or complicated drag operation. .

Accordingly, an object of the present invention is to provide a character input method using a touch screen which can be commonly used for inputting Korean, English and numbers, and has a fast input speed and a simple input operation.

In order to achieve the above object, the present invention provides a character input method using a touch screen for dragging or clicking a character displayed on an input window of a touch screen to display a desired character on a display window.

Selecting one of a Korean input mode, an English input mode, and a numeric input mode according to the type of characters to be input to display a predetermined input cell having different input information in an input window; Recognizing a start point and an end point of a drag starting at one of the input cells and ending at another input cell, and a click on one of the input cells as a text input signal; Displaying unit characters corresponding to each input cell in order on the display window according to the character input signal; Characterized in that it comprises a.

According to the first embodiment of the present invention, the input cell is a character cell corresponding to a predetermined basic unit character and a function cell for changing the type of unit character corresponding to each of these character cells. In this case, the basic unit character is input directly to the character cell, the unit character other than the basic unit character is characterized in that the input using the character cell and the function cell together.

According to the second embodiment of the present invention, the input cell is composed of a character cell corresponding to a predetermined basic unit character so that the basic unit character is directly input to the character cell, and unit characters other than the basic unit character are next. It is characterized by input through the five application drag operation described.

According to the present invention, it is possible to quickly input two unit letters, for example, two alphabetic letters or two Arabic numerals, or a Korean character composed of consonants and vowels in one simple drag operation.

In addition, the arrangement structure of the input cells displayed in the input window is very simple, and the input operation is simple, so that the user can easily learn the input method.

The character input method according to the present invention can be used for all portable electronic devices equipped with a touch screen, such as a mobile phone or a notebook computer, as well as a PDA (Personal Digital Assistant), navigation, ATM (Automatic Teller Machine), electronic dictionary, digital broadcasting terminal, etc. Can be applied.

Hereinafter, the present invention will be described in detail. However, even if the configuration falls within the technical scope of the present invention, a detailed description thereof will be omitted for the same techniques as those in the prior art or those skilled in the art.

As is well known, a touch screen is a type of input device provided in a portable information terminal, and is divided into a display window made of an LCD and an input window made of a touch pad, and the input window is divided into a plurality of input cells. The present invention relates to a character input method using a touch screen in which a user using the portable information terminal selects an input cell displayed on an input window and displays a desired character on the display window.

In the present invention, first, one of a Korean input mode, an English input mode, and a numeric input mode is selected according to the type of characters to be input. Then, a plurality of predetermined input cells having different input information are displayed in the input window.

Next, the user drags or clicks the input cell with a touch pen to select the corresponding character. In this case, the present invention recognizes the input cell corresponding to the start point and the end point of the drag, and the clicked input cell as text input signals, respectively. Therefore, the unit characters corresponding to each input cell are displayed in the display window in order according to the character input signal.

In the first embodiment of the present invention, the input cell is a character cell corresponding to a predetermined basic unit character and a function cell for changing the type of unit character corresponding to each of the character cells. Is done. Thus, the basic unit text is directly input to the text cell, and the unit text other than the basic unit text is input by using a text cell and a function cell together.

First, in the case of the Hangul input mode, as shown in Table 1, at least nine character cells corresponding to the basic consonants 'ㄱ, ㄴ, ㄹ, ㅅ, ㅇ, ㅁ' and the basic vowel 'ㅏ, ㅗ, ㅣ' and At least three function cells corresponding to 'sound, stroke, and sound' are used.

<Table 1>

A ㅗ M ㅇ ㅏ N S ㅣ D Sound Add stroke A wild sound

For example, if you want to enter '가', you can start the drag in the consonant 'ㄱ' cell and finish the drag in the vowel 'ㅏ' cell. And if you want to enter the ‘strong’ character, you can type ‘가’ in the same way, and then click on the ㅇ. As such, the basic unit characters shown in the input cells of Table 1 may simply input the Hangul Chinese characters by simply dragging or clicking each character cell.

However, unit characters other than the basic unit characters of Table 1 are inputted by using a text cell and a function cell together. For example, if you drag from the 'ㄴ' cell to the 'Add stroke' cell, 'ㄷ' is entered, and if you click on the 'old sound' cell again, 'ㄸ' is entered. In addition, to enter 'bokja' ‘ㄴㅈ’, first click on the 'ㄴ' cell and then drag from the 'ㅅ' cell to the 'add stroke' cell. Table 2 shows the functions of each function cell.

<Table 2>

Basic collection Sound Add stroke A wild sound Add Stroke → Sound Rough sound → Add stroke A ㄲ Lol N C ㅌ ㄸ D M ㅂ ㅍ ㅃ S ㅆ ㅈ H ㅉ ㅇ ㅎ ㅏ ㅑ ㅓ ㅕ ㅗ ㅛ TT ㅠ ㅣ ㅢ ㅡ

On the other hand, in the vowel, dragging from the 셀 cell to the ‘roughness’ cell enters ㅓ, and then clicking the add stroke cell again enters ㅕ. Drag '' from the 'ㅏ' cell to the 'ㅣ' cell, and drag 'ㅖ' from the 'ㅏ' cell to the 'rough' cell, and then drag from the 'Add' cell to the 'ㅣ' cell. .

As described above, in the first exemplary embodiment of the present invention, all Korean characters can be input using only a simple drag and click operation by using the nine character cells and three functional cells shown in Table 1 above. In the input cell of Table 1, some function cells corresponding to 'offset, period, comma', etc. may be additionally arranged as necessary.

Next, in the English input mode, as shown in Table 3, at least nine letter cells corresponding to two or three lowercase letters and at least three function cells corresponding to 'uppercase, second, and third' are used.

<Table 3>

spy tqk rdj iuv e_g nlw afx ozc hmb capital letter second third

In Table 3, the first alphabet of each character cell is a basic unit character. Therefore, the first alphabet of each character cell is directly input using the corresponding character cell, and the second and third alphabets and capital letters are input together using the corresponding character cell and function cell. For example, in order to input a lowercase 'a', a character cell 'afx' is clicked. In order to input an uppercase 'A', a character cell 'afx' is dragged from a function cell 'uppercase'. 'F' is inputted by dragging the function cell 'second' from the text cell 'afx', and 'x' is inputted by dragging the function cell 'third' from the text cell 'afx'. To input the English letter 'The', first drag the letter cell 'tqk' from the function cell 'uppercase', type 'T', and then drag the letter cell 'hmb' from 'e_g'.

Next, in the numeric input mode, the input cells shown in Table 4 can be used.

<Table 4>

One 2 3 4 5 6 7 8 9 - 0 +

In Table 4, drag the character cell '1' to '2' to input the number '123', and then click the character cell '3', and the character cell '5' to input the number '5159' Drag from to '1' and then drag from '5' to '9'. Thus, in the numeric input mode, as shown in Table 4, all the necessary character cells can be arranged in the 12 input cells, so that the function cells do not need to be arranged separately.

On the other hand, the second embodiment of the present invention is a method not using the functional cell. That is, the input cell is composed of a character cell corresponding to a predetermined basic unit character, and the basic unit characters of Tables 1 and 3 are directly input to the character cell, and unit characters other than the basic unit characters are the following five applications. Input by drag operation. In the following application drag operation, the term 'input cell area' refers to a set of character cells, that is, inside the outline of Table 1 or Table 3.

A) Exit: Start at any text cell and move out of the input cell area without going through another text cell.

B) Exit through: Start with an arbitrary text cell, go through another text cell, and move out of the input cell area to end.

C) Returning back: Start from any text cell and move to another text cell without exiting the input cell area and return to the original text cell and end.

D) Exit and Return: Starts at any text cell and immediately exits the input cell area and returns to the original text cell and ends.

E) Go through and return: Start with an arbitrary text cell, go through another text cell, go out of the input cell area, and return back to the original text cell.

The five application drag operations correspond one-to-one with the functions of the functional cells of the first embodiment, respectively. For example, in the Hangul input mode of the Hangul input mode, the application click action 'Exit (A)' corresponds to the function cell 'Add Stroke', and the 'Exit (B)' corresponds to the 'Gross Sound', C) corresponds to 'daughty sound' and 'out of return' (D) corresponds to 'daughty sound' followed by 'add stroke'. In the vowel input, the application click action 'Exit (A)' corresponds to the function cell 'Add Stroke', 'Outgoing (B)' corresponds to 'Grossing Sound', and 'Returning Back' is 'Grossing' This is equivalent to adding strokes.

Therefore, in the Hangul input mode according to the second embodiment of the present invention, at least nine text cells corresponding to the basic consonants 'a, b, d, s, ㅇ, ㅁ' and the basic vowel 'ㅏ, ㅗ, ㅣ' are used. . Thus, the nine basic unit characters are directly input through the corresponding text cell, and the unit characters other than the basic unit characters are input through five application drag operations as shown in Table 5 below.

 <Table 5>

Basic collection A N D M S ㅇ ㅗ ㅏ ㅣ Exit (A) Lol C ㅂ ㅈ ㅎ Exit (B) Lol ㅌ ㅍ H ㅎ TT ㅓ ㅡ Return via (C) ㄲ ㅆ ㅛ ㅑ ㅢ Exit and Return (D) ㄸ ㅃ ㅉ Passing Through and Returning (E) ㅠ ㅕ

Meanwhile, in the English input mode, at least nine character cells corresponding to two or three lowercase alphabet letters are used. The first alphabet of each character cell is the basic unit character and is directly input by using the corresponding character cell. The second and third alphabets are entered through the following five application drag operations.

A) Exit: Enter the second alphabet

B) Exit by: Enter the third alphabet

C) Return through: Uppercase letters of the basic alphabet

D) Exit and Return: Uppercase of Second Alphabet

E) Passing Back: Capital Letters of the Third Alphabet

As described above, in the first embodiment of the present invention, all Korean and English characters may be conveniently input using nine text cells and three function cells. In the second embodiment, nine text cells and five application drag operations may be used. Only Korean and English can be entered conveniently. In addition, in the numeric input mode, all numbers can be conveniently input without using the function cell or application drag operation.

In the Hangul input mode according to the present invention, the arrangement of the dials as shown in Table 1 is determined by referring to 'National Institute of Korea 2005-1-33, Modern Korean Language Usage Frequency Survey'. That is, the frequency of consonants is: consonant o, star b, star o, star o, star o, o o ㅁ, followed by finality ㅆ. Therefore, based on the frequency of use, reconstructed into basic consonants, it can be seen that o, a, g are used relatively frequently in the initial position, and b, d, k are used frequently in the final position. Therefore, the left three columns of the input button are arranged with o, a, s and the right three columns with b, d, ㅁ.

Although the preferred embodiment of the present invention has been described above, the scope of the present invention is not limited to these embodiments. Those skilled in the art may display application characters other than those shown in Tables 1 and 5 within the same range as the object of the present invention, and may change the layout of the dial or the type of text cells and functional cells in more various ways. There will be. However, it will be construed that it falls within the scope of the present invention, unless such design changes result in no novel effects foreseen in the present invention.
