English input method using touch screen {METHOD FOR INPUTTING ENGLISH TEXT BY USING TOUCH SCREEN}

The present invention relates to an English letter input method, and more particularly, to an English letter input method using a touch screen used in electronic devices such as mobile communication terminals, personal digital assistants (PDAs), remote controls, and the like.

Due to the development of information communication, the use of mobile communication terminals, PDAs, and other devices for transmitting and receiving information is increasing, so that characters are inputted using mobile communication terminals. With the development of wireless communication, mobile communication terminals are becoming an indispensable necessity, and it is expected that more characters will be inputted by using keypads of electronic devices with better value-added services.

1A and 1B show a keypad for explaining a conventional English letter input method, respectively. 1A and 1B show only the keypad of the conventional mobile communication terminal, and the illustration of the rest of the keypad is omitted. As shown in the figure, three to four alphabetic characters are assigned to the keypads corresponding to the numbers 1 to 10, and there is a difficulty of typing two or three times or four times to input a desired alphabetic character.

For example, if the keypads of FIGS. 1A and 1B are used to input GOOD MORNING, a total of 26 keypads should be touched, such as '4666 → 6663 → 6 → 66677766444664'. There is a disadvantage to press several times.

On the other hand, input devices using touch screens have been widely used in electronic devices such as mobile communication terminals. 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 an 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 a point on the touch pad and a 'drag' continuously moving from one point to another.

On the touch screen as described above, the English letter input method as shown in FIGS. 1A and 1B is used, and there is a problem in that the English letter input is inconveniently similar to the keypad method described above.

The present invention has been proposed to solve the above problems, to recognize the starting point and the end point of the drag on the keypad displayed on the input window of the touch screen as a text input signal, so that the English alphabet maneuver easily with a single drag An object of the present invention is to provide an English letter input method using a touch screen.

In order to achieve the above object, the English character input method for inputting at least one alphabetic character assigned to a predetermined number of keypad cells displayed on the touch screen of the present invention by the user's drag input, end point and time of the drag If the same and there is no movement to another cell, displaying the first alphabetic character of the cell corresponding to the viewpoint; And when the end point and the start point of the drag are different, checking the number of movements N in the vertical or horizontal direction of the dragged cell, and displaying the N + 1th English letter of the cell corresponding to the start point. If the end point and the start point of the drag are the same, it is preferable to further include the step of checking the drag path and, if other cells are included in the drag path, displaying the final alphabet characters of the cell corresponding to the start point.

In addition, the English character input method for inputting at least one alphabet letter assigned to a predetermined number of keypad cells displayed on the touch screen of the present invention by a user's drag input has the same end point and time point as the drag and moves to another cell. If not, displaying the first alphabetic character of the cell corresponding to the viewpoint; If the end point of the drag moves vertically or horizontally by one cell from the viewpoint, displaying a second alphabetic character of the cell corresponding to the viewpoint; If the end point of the drag moves vertically or horizontally by two cells from the viewpoint, displaying a third alphabetic character of the cell corresponding to the viewpoint; And displaying the fourth alphabetic character of the cell corresponding to the viewpoint when the end point of the drag is moved vertically or horizontally by three cells from the viewpoint. In this case, when the end point of the drag and the viewpoint are the same, the drag path is displayed. When the check path includes other cells in the drag path, the method may further include displaying a fourth alphabetic character of the cell corresponding to the viewpoint.

On the other hand, a program of instructions are implemented in a tangible manner for performing an English character input method for inputting at least one alphabetic character assigned to a predetermined number of keypad cells displayed on the touch screen of the present invention by a user drag input. The recording medium on which a program which can be read by the digital processing apparatus is recorded includes the steps of: displaying the first alphabetic character of the cell corresponding to the viewpoint when the end point and the viewpoint of the drag are the same and there is no movement to another cell; And when the end point of the drag and the starting point are different, determining the number of movements N in the vertical or horizontal direction of the drawn cell, and displaying the N + 1 th alphabetic character of the cell corresponding to the starting point. In this case, when the end point and the start point of the drag are the same, it is preferable to perform the step of checking the drag path and, if other cells are included in the drag path, displaying the final alphabet characters of the cell corresponding to the start point. .

As described above, the present invention has the effect of allowing the user to input English letters quickly with a single simple drag operation, and by simplifying the English letter input cell, the user can easily input English letters.

In addition, the English letter input method of the present invention can be used in all portable electronic devices, for example, a mobile communication terminal equipped with a touch screen, as well as navigation, ATM (Automatic Teeler Machine), electronic dictionary, digital broadcasting terminal.

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

For input of alphabetic characters, the user may perform a task of causing the keypad to be displayed on the touch screen. As for the technology of displaying the keypad on the touch screen, it will be obvious to those skilled in the art, and detailed description thereof will be omitted.

First, a keypad to which the English letter input method of the present invention is applied will be described.

In the keypad for application of the present invention, as illustrated in FIG. 2, three to four English letters are assigned to each number of the keypad. In one embodiment of the present invention, the number '2' is an English letter 'ABCD', the number '3' is an English letter 'EFG', the number '5' is an English letter 'HIJK', and the number '6' is an English letter 'LMN' The number '8' is assigned the English letter 'OPQR', the number '9' is assigned the English letter 'STU', the number '0' is assigned the English letter 'VW' and the sign '#' is assigned the English letter 'XYZ'. For convenience, each key of the keypad will be referred to as a 'cell'. That is, the keypad to which the present invention is applied is composed of 12 cells, and each cell is assigned a number and an English letter.

 2 is for explaining an embodiment of the present invention by way of example, the arrangement of the letters of the English may be configured differently from the drawings, such an example to limit the character input method of the present invention It is not.

3 is a configuration diagram of an English alphabet input device to which the present invention is applied.

As shown in the figure, the input device of the present invention includes an input unit 11, a control unit 12, a display unit 13, and a database (hereinafter, simply referred to as 'DB') 14. . In the case of a touch screen to which the present invention is applied, the input unit 11 may be in the form of a keypad displayed on the display unit 13, and as for the touch screen related technology, since it is already known, the detailed description thereof will be omitted. I will omit it. In the DB 14, a keypad constituting the input unit 11 may be stored, and an English letter assigned to each keypad may be stored. When a user inputs an English letter by clicking or dragging by the English letter input method of the present invention, the control unit 12 is responsible for a function of causing the display unit 13 to recognize the English letter from the input of the corresponding click or dragging method.

Hereinafter, an English letter input method of the present invention recognized by the controller 12 will be described with reference to the drawings.

In the alphabetic character input method of the present invention, in order to input the first alphabetic character, the keypad cell displayed on the corresponding touch screen may be clicked using a touch pen or a hand, as in the conventional character input method. Thus, the control unit 12 recognizes the start point and the end point of the drag, and if the end point is a 'click' as the start point, it recognizes this as inputting the first character assigned to the cell of the start point. Control to display this on the display unit 13. Another case where the end point and the same point are the same will be described later.

4A to 4D are exemplary views for explaining an English letter input method according to the present invention. Each of these will be described in detail.

FIG. 4A is an exemplary diagram for describing a method of inputting a second English letter, and an arrow illustrates a path dragged by a user using a touch pen or a hand. For simplicity, illustration of the touch pen or hand is omitted. Hereinafter, in the description of the present invention.

In order to input the second letter 'B', the user drags one cell starting from the corresponding cell (ie, cell '2'). In this case, however, the direction of drag is irrelevant. That is, it may be dragged vertically as shown in S21 or may be dragged horizontally as shown in S22. All other directions that can be dragged will be omitted, but are not excluded. In this way, when there is a user input, the controller 12 recognizes the starting point and the end point of the drag, and when the end point is separated by one cell from the starting point, the control unit 12 determines the second character assigned to the cell at the starting point ( B ') is recognized as an input and control to display it on the display unit 13.

FIG. 4B is an example for explaining a method of inputting a third English letter, and an arrow illustrates a path dragged by a user using a touch pen or a hand.

To input 'C', the third character, the user drags two cells starting from the cell (that is, cell '2'). In this case, however, the direction of drag is irrelevant. That is, it may be dragged vertically as in S23, may be dragged in a curved form as in S24, or may be dragged in a diagonal direction as in S25. All other directions that can be dragged by two spaces will be omitted, but this is not an exclusion. As such, when there is a user input, the controller 12 recognizes the starting point and the end point of the drag, and when the end point is two cells away from the starting point, the controller 12 determines the third character ('C in FIG. 4C) assigned to the cell at the starting point. ') Is recognized as an input and control to display it on the display unit 13.

FIG. 4C is an exemplary view for explaining a method of inputting a fourth English letter, and an arrow illustrates a path dragged by a user using a touch pen or a hand.

To input the fourth letter 'D', the user drags the cell three spaces starting from the cell (ie, cell '2'). In this case, however, the direction of drag is irrelevant. That is, it may be dragged vertically as shown in S26, or may be dragged in a curved form as shown in S27. All other directions that can be dragged in three spaces will be omitted, but this is not an exclusion. As such, when there is a user input, the controller 12 recognizes the starting point and the end point of the drag, and when the end point is separated by three cells from the starting point, the controller 12 determines the fourth character ('D in FIG. 4C) assigned to the cell at the starting point. ') Is recognized as an input and control to display it on the display unit 13.

That is, when the above description is extended, the control unit 12 checks the number of movements N in the vertical or horizontal direction of the dragged cell, and it will be described as displaying the English letter corresponding to the N + 1th cell in the cell corresponding to the viewpoint. Can be. For the sake of convenience, up to four English letters are allocated to each cell, but the present invention is not limited thereto.

On the other hand, Figure 4d is an exemplary view for explaining another method of inputting the fourth English letter, the arrow describes the path that the user drags using a touch pen or hand.

In order to input the fourth character 'D', the user drags the cell starting from the cell (that is, cell '2') through another cell and back to the cell. However, in this case, the drag direction is irrelevant and may be dragged horizontally as shown in S28, or, although not shown, may be dragged vertically or diagonally, and the user may return to the corresponding cell again. When there is such a user's input, the control unit 12 recognizes the starting point and the end point of the drag, and if the starting point and the end point are the same and there are traces dragged to another cell, the control unit 12 determines the fourth character ( In FIG. 4D, it is recognized that 'D' is input, and the display unit 13 controls to display it on the display unit 13.

For convenience, the method for inputting the fourth alphabetic character has been described with reference to FIG. 4D, which may be changed according to the number of alphabetic characters assigned to the keypad cell, and corresponds to a method of inputting the final alphabetical character. It will be self-evident to those who have knowledge.

5 is a flowchart illustrating an example of an English character input method of the present invention.

As shown in the figure, in the English letter input method of the present invention, when the user drags the touch screen provided by the input device to which the present invention is applied (S51), the control unit 12 determines the dragged path of the user. Check and determine whether the end point and the point of the drag is the same (S52). In this case, the controller 12 determines whether other cells are included in the drag path (S53), and when the end point and the same point are the same, when the other cell is not included in the drag path, the first cell of the cell corresponding to the point in time is included. The English letter is displayed on the display unit 13 (S54), and when another cell is included in the drag path, the fourth English letter of the cell corresponding to the viewpoint is displayed on the display unit 13 (S55).

If the end point and the point of view are not the same, it is checked how many cells are moved (S56). When the number of cells is moved vertically or horizontally by one cell, the second alphabetic character of the cell corresponding to the point of view is displayed. (S57). If two cells are moved vertically or horizontally, the third alphabetic character of the cell corresponding to the viewpoint is displayed on the display unit 13 (S58). On the other hand, when moving vertically or horizontally by three cells, the fourth alphabetic character of the cell corresponding to the viewpoint is displayed on the display unit 13 (S55).

Subsequently, the above steps S51 to S58 are repeatedly performed until the user ends the drag (S59), that is, until the character input is completed.

In the description of the present invention, it is assumed that the maximum number of alphabetic characters assigned to a cell is four. However, the present invention is not limited thereto.

According to the present invention as described above, it is possible to quickly enter the alphabetic characters with a single simple drag operation, by simplifying the input cell, the user can easily enter the alphabetic characters.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.
