CHARACTER INPUT APPARATUS AND METHOD FOR AUTOMATICALLY SWITCHING INPUT MODES IN TERMINAL HAVING TOUCH SCREEN}

The present invention relates to a method of inputting a character, and more particularly, to a character input device and method for automatically switching the input mode in a terminal having a touch screen.

A text input method (hereinafter, referred to as a 'T9' method) among character input methods in a conventional terminal refers to a method of outputting a commonly used word by a combination of key inputs. The T9 method is a method for predicting a character to be input by a user in advance to improve the inconvenience of the existing character input method. In the T9 method, the user can output the desired word by pressing the key to which the character is assigned only once. This will be described in detail with reference to FIG. 1, which is a diagram illustrating a key input unit in a conventional terminal.

When the user wants to input 'pizza' in the key input unit configured as shown in FIG. 1, the numeric keys including each character are '7,4,4,4,1,1,1,1,1,1,2' Press in order. In other words, the user has to press the key to which the character is assigned several times in order to input the desired character. For example, when inputting 'z', the user must press the corresponding key 101 four times to select 'z' among four characters of 'wxyz' in the key 101 to which 'wxyz' is assigned. It can also be confusing to users if they enter any one character assigned to the same key multiple times.

However, in the T9 method, the key 104 assigned with 'p', the key 103 assigned with 'i', the key 101 assigned with 'z' and the key 102 assigned with 'a' are once each. You can print out the desired character 'pizza' by pressing it. In other words, in the T9 method, the terminal allows the user to enter the number keys '7', '4', and '1', each of which includes the letters 'p', 'i', 'z', 'z', and 'a'. If you press, '1', '2', it will output 'pizza', which is the word predicted by searching the pre-stored dictionary. Therefore, the user has the convenience of inputting desired characters with fewer key inputs than using the conventional character input method through the T9 method.

However, in the T9 method, a problem occurs when a user tries to input a proper noun. In the T9 method, only words predicted according to a user's key input can be input, so the user must switch the input method to select a character to be input. That is, the user needs to switch from the mode using the T9 method to the mode in which the characters can be selected individually, but can input the desired characters. To do this, the user has to enter an additional key for mode switching. In particular, when the sentence is composed of several words, the user must press the mode switching key one by one, and thus, the number of key presses can be greatly increased as a whole. This is because even if the user presses the mode switch key, the characters displayed in the key input unit remain the same. That is, even if the mode is inputted one by one, two or more characters are still assigned to one key, and the key input according to the character selection is inevitably increased.

As such, in a conventional terminal, a user must perform a separate operation for mode switching in order to input a desired character such as a proper noun when inputting a character in a T9 mode. Therefore, the user needs to select a mode and input characters, which requires more effort for key input. In addition, in order to input characters one by one, a plurality of key inputs are required until the corresponding characters are output, which causes a problem in that the character input process is complicated and time is delayed.

As described above, when a character is input in the T9 mode, the user has to change the mode in a separate method in order to input a proper noun. Accordingly, the conventional character input method requires an operation for changing the mode each time a character is input, which is cumbersome and delays the character input time. In addition, even if the conventional key input unit is switched to the individual input mode, there is a configuration problem that a plurality of key inputs are required to select a character.

Accordingly, the present invention provides a character input device and method for automatically switching the input mode in a terminal having a touch screen for selecting a desired input method more simply to input a character with a quick operation.

In addition, the present invention provides a character input device and method for automatically switching the input mode in the terminal having a touch screen for efficiently reducing the character input time by quickly switching to a mode that can selectively enter the desired character in the T9 mode to provide.

In accordance with another aspect of the present invention, there is provided a text input method for automatically switching an input mode in a terminal having a touch screen, wherein the text areas generated by dividing an area on the touch screen into two or more areas. Assigning and displaying a character group including two or more characters in each of the characters, and dragging before a release event occurs when a press event occurs in any one of the character regions. Drag) a process for determining whether an event occurs, the individual character input mode for inputting any one character in the character group according to whether or not the drag event occurs and a word including any one character in the character group Characterized in that it comprises the step of performing any one of the text input mode for input All.

In addition, the present invention provides an advantage that can be utilized in various input devices including a terminal with a touch screen.

DETAILED DESCRIPTION Hereinafter, detailed descriptions of preferred embodiments of the present invention will be described with reference to the accompanying drawings. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

The present invention provides a character input device and method for automatically switching the input mode in a terminal having a touch screen. Accordingly, when the press event occurs in any one of the text areas displayed on the touch screen, the terminal determines whether a drag event occurs before the release event occurs. Accordingly, any one of an individual input mode for inputting any one character in the corresponding character group and a text input mode for inputting a word including any one character in the corresponding character group is performed. Such a method provides a user with a convenience of quickly selecting a desired input mode to input characters more easily.

Hereinafter, a block diagram of an apparatus for inputting text according to an exemplary embodiment of the present invention will be described with reference to FIG. 2.

Referring to FIG. 2, the apparatus for inputting a text includes a wireless unit 200, a memory 210, a touch screen 220, and a controller 230. First, the wireless unit 200 performs a wireless communication function of the terminal.

In addition, the memory 210 includes a read only memory (ROM) and a random access memory (RAM) for storing a plurality of programs and data, and is particularly used in a text input mode according to an embodiment of the present invention. Stores words according to the key combination. The memory 210 stores a group of characters formed by consonants and vowels of Korean characters displayed in the character area of the touch screen 220, upper and lower case letters of English alphabet, numbers, and special characters (hereinafter, referred to as 'characters'). do. Character groups are divided depending on the total number of character areas. Specifically, the number of character groups is generated equal to the number of character regions, and the larger the number of character regions, the smaller the number of characters constituting one character group. The number of character groups may be adjusted to the most efficient number for receiving characters from the user corresponding to the screen size of the touch screen 220. In an exemplary embodiment of the present invention, character groups consisting of three to four English alphabets are displayed on the 3x3 character area of the touch screen 220.

The touch screen 220 refers to a screen that detects the location of a person's hand or an object on a character or a specific location displayed on the screen so that specific processing can be performed by the stored software. The touch screen 220 receives a touch input from a user and displays display data under the control of the controller 230, or displays an operation state and a plurality of information of the mobile communication terminal as icons and text. In particular, the touch screen 220 to which the present invention is applied displays a text area capable of receiving text under the control of the controller 230, and according to a user's input, press event, release event, and dragging. Raises the (Drag) event. Here, the press event is generated when the text area is pressed. That is, the press event is generated when there is a touch input by the user in the text area. On the other hand, the release event occurs when the pressing of the text area is released, the drag event occurs when the user's drag input on the text areas displayed on the touch screen 220.

The controller 230 allocates and displays character groups each including two or more characters in the character regions output on the touch screen 220. The controller 230 determines whether a drag event occurs before a release event occurs when a press event occurs in any one of the character areas, and inputs any one character from the corresponding character group according to whether a drag event occurs. One of the individual input modes and the text input mode for inputting a word including any one character from the corresponding character group is performed.

In addition, when the press event occurs in any one of the text areas in a manner different from that described above, the controller 230 counts the time from the time when the press event occurs. Then, the controller 230 determines whether the counted time exceeds a pre-stored threshold value, and performs one of the individual input mode and the text input mode according to the determination result. Details thereof will be described in detail with reference to FIG. 3.

3 is a control flowchart for automatically inputting a character by automatically switching an input mode according to an exemplary embodiment of the present invention.

Referring to FIG. 3, the controller 230 proceeds to step 300 in a text input mode set as a default, and allocates and displays a character group for each character area. Herein, the text input mode refers to a mode for inputting a desired word by pressing the text area only once. In the present invention, a case of using the T9 method will be described as an example.

The controller 230 determines whether a press event occurs in step 302. In an embodiment of the present invention, the press event occurs when the character area is pressed. If a press event occurs, the controller 230 proceeds to step 304 to measure the touch input time. In this case, the touch input time is counted and measured from the time when the press event occurs. The measured time is for determining whether the touch input through the text area is long or short, and the controller 230 may check the comparison with a previously stored threshold value. That is, the controller 230 determines that the touch input is long when the measured time exceeds the threshold value, and otherwise determines that the touch input is short. Accordingly, the controller 230 determines whether a release event occurs within a threshold in step 306. When the release event does not occur within the threshold, that is, when the measured time exceeds the threshold, the controller 230 proceeds to step 308 to switch to the individual character input mode. Details of the individual character input mode will be described in detail with reference to FIG. 4.

4 is a diagram illustrating a process of inputting a character in an individual character input mode according to an exemplary embodiment of the present invention.

If any one of the text areas displayed as shown in FIG. Mark on. In this case, the characters are reassigned to the existing character regions as shown in FIG. 4 (b) and displayed. In particular, in the remaining portions except for the portion where the character groups of other character regions are displayed in addition to the character region where the press event occurred. It can be assigned and displayed one by one. This is to reduce the time for inputting the text as a whole by allowing the user to continuously view the entire text area, thereby facilitating selection of the next character after inputting the text.

 As described above, the controller 230 proceeds to step 312 in which the characters of the text area where the press event has occurred are displayed one by one to determine whether a drag event occurs. When the drag event occurs, the controller 130 proceeds to step 314 to move the indicator according to the occurrence of the drag event.

According to an exemplary embodiment of the present disclosure, when a drag event occurs in the text area, the controller 230 determines which of the text areas in which the text area indicated by the distance and direction of the drag event is displayed in the text area in which the press event occurs. Determine if it is equal to one.

If it is determined that the same character area is the same, the controller 230 highlights the indicated character area. According to an embodiment of the present invention, an indicator is displayed for highlighting, where the indicator is to display the selected text area with a visual effect so that the user can recognize the text area. For example, the indicator changes the color of the edge of the key area or displays the key area in shade to show that the key area is selected. Thus, through this indicator, any text area is highlighted according to the drag event. The highlighted text area may be changed according to the drag event. Accordingly, the controller 230 outputs a character to the input editor window in accordance with the movement of the indicator in step 316. In other words, whenever the text area is highlighted, the controller 230 outputs the text of the highlighted text area to the predetermined input editor window 400 on the touch screen 220. Therefore, the characters output in the input editor window 400 may vary depending on the drag event. In this case, the character is output at the corresponding position of the cursor indicating the input position of the character, and the position of the cursor is not changed according to the drag event, but only the output characters are changed. As such, the controller 230 outputs the text of the highlighted text area to the input editor window 400 whenever the text area is highlighted, thereby providing the user with the convenience of selecting the desired text more accurately and easily.

Meanwhile, as described above, in the state in which characters are output according to the drag event, the controller 230 determines whether a release event occurs in step 318. According to an embodiment of the present invention, the user selects a desired character by dragging the character area and inputs the selected character by releasing the pressing of the character area. Therefore, the controller 230 detects whether a release event occurs after the drag event occurs. In the present invention, the occurrence of the release event is used in the same sense as the input of the character. Accordingly, when the release event occurs, the controller 230 proceeds to step 318 to output a character corresponding to the character area in which the release event occurs. Referring to FIG. 4C, when the release event occurs while the indicator is moved from the character area where 'jkl' is displayed to the character area where 'l' is displayed due to the drag event, the character of the character area where the indicator is located is 'l' is output to the input editor window 400.

As described above, when the text area is pressed for a short time, the user may individually select and input a desired text. On the contrary, the user can enter a word at a time by simply pressing and holding the desired letter area. In other words, the user can directly enter a desired word using the T9 method.

In detail, when the release event occurs within the threshold in step 306, the controller 230 determines that the touch input is short because the measured time does not exceed the threshold and proceeds to step 320. In step 320, the controller 230 checks the characters of the character area in which the release event occurs. The controller 130 detects a word including any one of the characters identified in step 322 and outputs the word detected in step 324.

According to an embodiment of the present disclosure, if the character area including 'jkl' is pressed for input of the first character, the controller 230 counts a time from a time point at which a press event occurs. The controller 230 determines whether a release event occurs in the character area including 'jkl' when the counted time is within a previously stored threshold. If it is determined that the release event has occurred, the controller 230 searches for a word including 'j', 'k', and 'l' which are characters of the character area including 'jkl' where the release event occurs. Herein, the controller 230 detects one word having the highest frequency of use among words beginning with j ',' k ', and' l ', and outputs the detected word to the input editor window 400. At this time, the input editor window 400 may display a plurality of words with a high frequency of use, and may output one word according to a user's selection. Alternatively, the word with the highest frequency of use may be automatically selected and output. .

On the other hand, the controller 230 is a case in which the character area including 'jkl' is not pressed for the input of the first character in the individual character input mode, that is, the user inputs additional characters while another character is already output. In this case, the corresponding word is detected by referring to the words according to the key combination stored in the memory 210. For example, if the user presses a character area allocated to 'tuv' while the 's' is already output, the controller 230 may refer to pre-stored words and the previously output 's' among the 'tuv'. The word 'sun', which is frequently used in combination, is output to the input editor window 400.

As such, the present invention has an advantage in that the user can automatically select a desired mode without a separate key input or manipulation for selecting the individual character input mode and the text input mode. In addition, according to the present invention, when a word or character is inputted and word classification is started by a space bar, the user can perform the above process again by automatically switching to the text input mode.

Meanwhile, according to an exemplary embodiment of the present invention, characters of a character area in which a press event occurs in an individual character input mode may be displayed as shown in FIG. 5 unlike the case of FIG. 4 described above.

5 is a diagram illustrating a method of displaying characters in an individual character input mode according to an exemplary embodiment of the present invention. Referring to FIG. 5, when a press event occurs in any one text area, characters of the text area where a press event has occurred may be enlarged and displayed in the text areas instead of the originally displayed text group.

When the text area in which the press event occurs is located at the leftmost side, the controller 230 may display all the characters of the text area in which the press event has occurred in a line as shown in FIG. 5 (a). When the number of characters allocated to one character area is large, as shown in FIGS. 5B and 5C, the controller 230 enlarges the characters in adjacent character areas surrounding the pressed-down text area, respectively. Can be displayed.

In FIGS. 5A, 5B, and 5C, each character is enlarged and displayed in the text areas except the text area in which the press event has occurred, It is possible to display one character enlarged, and as shown in FIG. 6, characters of a character area in which a press event has occurred may be displayed using a popup window format.

6 is a diagram illustrating a method of displaying characters in a pop-up window format in an individual character input mode according to an exemplary embodiment of the present invention. As shown in FIGS. 6A and 6B, when a press event occurs in any one text area, a popup window having a horizontal or vertical form is output based on the text area where the press event has occurred. That is, the controller 230 enlarges and displays characters in the text area in which the press event occurs in two or more text areas in the form of a pop-up window. The manner in which the pop-up window is output is not limited, and may be variously implemented within a range for improving user convenience according to an exemplary embodiment of the present invention.

As described above, in the present invention, characters of the text area pressed down in the individual text input mode are reassigned to each text area and displayed or enlarged in two or more text areas in the form of a pop-up window. It can be displayed in a way. In addition, although the embodiment of the present invention has been described as being limited to the English alphabet, it is also possible to be applied to various types of characters such as Korean and special characters.

In the above-described embodiment of the present invention, a time is counted after a press event occurs, and any one mode is performed based on the counted time. However, according to an exemplary embodiment of the present invention, any one mode may be performed depending on whether a drag event occurs before the release event occurs after the press event occurs. Specifically, the controller 230 performs a text input mode in which a word can be input at a time when a release event occurs after a press event occurs, that is, when a drag event does not occur. If it is determined that the drag event has occurred, the controller 230 switches to the individual character input mode and receives any one character from the user.

On the other hand, the controller 230 may receive any one character only by the drag event without switching the screen when the mode is switched.

Hereinafter, a control flowchart for inputting a character in a selected mode according to the presence or absence of a drag event will be described with reference to FIG. 7. Referring to FIG. 7, in the text input mode, the controller 230 proceeds to step 700 and allocates and displays a character group for each character area. The controller 230 determines whether a press event occurs in step 702. According to an embodiment of the present invention, the initial screen in the text input mode is displayed as shown in FIG. 8. In the character area of FIG. 8, characters are centrally displayed according to an exemplary embodiment of the present invention, and it is also possible that characters are allocated together with any one number as in the existing character areas.

Meanwhile, FIG. 8 exemplarily illustrates that a text area in which 'ABC' is displayed among all the text areas is selected. Then, the user can select any text area 800 in which 'ABC' is displayed among the text areas. According to an embodiment of the present invention, when the user selects any one character area in the text input mode, a pop-up window 810 indicating the text input mode is output. Therefore, the user has the convenience of inputting a character by recognizing the current input mode.

As such, when it is determined that the press event occurs in any one text area according to the user's selection, the controller 230 proceeds to step 704 to measure the touch input time. That is, the controller 230 measures the time counted from the time when the press occurred. Accordingly, the controller 230 determines whether a release event occurs within a preset threshold time in step 706. If it is determined that the release event has not occurred, the controller 230 proceeds to step 708 to detect the drag event. In the embodiment as shown in FIG. 7, the drag event is used as a reference for switching from the text input mode to the individual character input mode. Therefore, if it is determined that the drag event occurs in step 710, the controller 230 proceeds to step 712 and switches to the individual character input mode. In operation 714, the controller 230 checks the distance and direction of the drag event, and displays one character corresponding to the checked distance and direction in the popup window. The character selection process in the individual character input mode will be described with reference to FIG. 9 for better understanding.

9 is a diagram illustrating a screen for selecting and inputting a character in an individual character input mode according to an exemplary embodiment of the present invention. In FIG. 8, when the user selects the corresponding text area by pressing the text area 800 in which 'ABC' is displayed, the controller 230 detects whether a drag event occurs before the release event occurs. When the drag event occurs, the controller 230 switches to the individual character input mode. In this case, the arrangement of the characters displayed in each character area is not changed even when the mode is switched.

Meanwhile, in the individual text input mode, the controller 230 displays one of the characters of the text area in which the press event has occurred on the screen according to the distance and direction of the drag event. For example, when the user drags in the left direction as shown in FIG. The popup window 900 is displayed. In addition, as shown in FIG. 9 (b), the controller 230 displays a letter 'B' located in the center when the user drags downward in the corresponding text area, and when the user drags right. As shown in Fig. 9 (c), 'C', which is displayed on the right side of 'B', is displayed on the popup window.

On the other hand, if four characters are allocated to one character area, that is, for example, the character area 910 in which 'PQRS' is displayed, the controller 230 is the letter 'Q' which is the second character located from the left of the four characters. The text corresponding to the drag event is displayed on the popup window. In detail, as described above, the controller 230 outputs a 'R' to a popup window when a drag event occurs to the right centering on the 'Q' in the character area of 'PQRS' and a drag event occurs to the left. Will print 'P' in the popup window. In addition, the controller 230 displays a 'Q' in a popup window when a drag event occurs downward. On the contrary, when receiving 'S', the controller 230 sets a position value away from the position at which the 'Q' is displayed by a specific distance, and when the drag event occurs at a distance greater than or equal to the set position value, the corresponding character 'S' Will print '. In this process, as well as the character input method when three characters are located, it is also possible to input the corresponding characters corresponding to the up, down, left, and right directions.

As such, the controller 230 displays one character corresponding to the drag input of the user, that is, the occurrence of the drag event through the pop-up window. Then, when the desired character is displayed in the popup window, the user can release the text area so that the corresponding character is displayed in the input editor window. Accordingly, the controller 230 determines whether a release event occurs in operation 718 and outputs a character displayed in the popup window in operation 720.

On the other hand, the controller 230 proceeds to step 722 to perform the text input mode as it is when the release event occurs within the threshold time, that is, the release event occurs after the press event in step 706. In operation 722, the controller 230 checks the characters of the character area in which the release event has occurred, and proceeds to operation 724 to detect a word including any one of the identified characters. Referring to FIG. 8, the controller 230 detects a word including any one letter of 'ABC' displayed in the character area 800 selected by the user. The controller 230 proceeds to step 726 to output the detected word.

As described above, the present invention provides various types of text input methods to provide a user with the ability to easily input text at a higher speed by selecting the desired text with minimal effort.
