The present invention relates to a method for inputting Chinese characters in a terminal, and more particularly, to a method for inputting Chinese characters more conveniently than the conventional method according to a stroke method, and a mobile terminal capable of implementing the same.

There are two ways to input Chinese characters in Chinese terminal: pinyin and stroke.

Pinyin is a method of inputting Chinese characters using the Chinese standard pronunciation of Chinese characters. The Pinyin method has been developed in various ways up to now, but recent research shows that about 50% of people who actually speak Chinese have difficulty acquiring accurate Pinyin pronunciation, making it difficult to pinyin based on Pinyin pronunciation.

The stroke method is a method of inputting kanji using the kanji standard stroke order. 1 and 2 will be described with respect to the Chinese character input method according to the conventional stroke method. The Chinese character input method in the Chinese terminal according to the stroke method can be divided into the Zi method and the T9 method again. Since the T9 method is used more in the Chinese terminal, it will be described below as the T9 method.

1 is a view showing a stroke order of the example "安" for explaining the Chinese character input method according to the conventional stroke method, Figure 2 is a diagram showing a keypad map of the T9 method for Chinese character input in a terminal for the Chinese. . In the keypad of FIG. 2, “?” Denotes a wild card and denotes the rest of the stroke other than the stroke on the keypad. This is because some strokes of Chinese characters cannot be put on the keypad, so some less-used strokes are tied together to correspond to "?".

First, in order to input "安", the terminal user inputs all the strokes constituting "安" using the keypad of FIG. 2 in the stroke order of FIG. That is, the keys "2", "2", "5", "6", "3", and "1" are pressed in sequence in the keypad of FIG. Then, the terminal inputs "安" corresponding to the stroke order.

However, people who actually use many Chinese characters do not know the stroke order of Chinese characters accurately, and thus make a mistake in the order of input of Chinese characters. In the current terminal, if an error occurs in the kanji stroke order, the user requires a cumbersome process of deleting the input kanji stroke and inputting it again in the correct stroke order.

Therefore, the present invention has been proposed to solve the above-mentioned problems, and even when inputting the Chinese characters by the stroke method in the terminal, it is possible to input the Chinese characters to be input more conveniently than in the prior art even if an error is inputted in the Chinese character stroke order. It is an object of the present invention to provide a Chinese character input method and a mobile terminal capable of implementing the same.

In order to achieve the above object, the present invention is a step of receiving a stroke of the input target kanji from the user, displaying a list of kanji corresponding to the input sequence of the stroke, the input target kanji in the list If not, the present invention provides a method for inputting Chinese characters in a mobile terminal, the method comprising the steps of rearranging the input sequence of the strokes, and displaying a list of Chinese characters corresponding to the input sequence of the rearranged strokes.

In order to achieve the above object, the present invention includes a display unit, an input unit for inputting a Chinese character stroke, and a control unit for controlling the display unit and the input unit, wherein the control unit is configured to input the target Chinese character from the user. Receives and displays a list of Chinese characters corresponding to the input sequence of the stroke, and if the input target Chinese characters are not in the list, the input sequence of the stroke is rearranged, and corresponds to the input sequence of the rearranged stroke It provides a mobile terminal for controlling the display unit and the input unit to display the list of Chinese characters.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention that can specifically achieve the above object will be described. Hereinafter, an embodiment of the present invention will be described taking the case of inputting Chinese characters in a T9 type Chinese terminal. However, it should be noted that the present invention can be applied not only to terminals for China, but also to all terminals capable of inputting a Chinese character based language in a stroke method (for example, terminals for Japan, terminals for Taiwan, etc.).

3 is a schematic block diagram illustrating a configuration of a terminal according to the present invention, and FIG. 4 is a front view of the terminal according to the present invention.

3 and 4, the terminal 10 according to the present invention, the input unit 100 for inputting Chinese characters, the display unit 200 for displaying Chinese characters, the memory unit 300 for storing the Chinese character database And a controller 400 controlling the input unit 100, the display unit 200, and the memory unit 300.

The input unit 100 has a T9 keypad and key buttons for operating other terminals. In particular, the first function key 110, the second function key 120, the navigation key 130, and the OK key 140 of the input unit 100 are used for the Chinese character input method according to the present invention. do. The use of the first function key 110, the second function key 120, the navigation key 130 and the OK key 140 for the Chinese character input method according to the present invention is merely an example, and the present invention is not limited to the above. Note that it is not only implemented through keys.

The display 200 again displays the first display unit 210 in which the inputted Chinese characters are displayed, and the components of the Chinese characters (hereinafter referred to as "input target Chinese characters") that the terminal user wants to input are displayed in the input order. The display unit 230 is preferably divided into a third display unit 250 in which a list of Chinese characters corresponding to the input order of the input strokes is displayed.

The memory unit 300 stores a database 350 of frequency information for each Chinese character. In the database 350, not only statistical information regarding general usage frequency (hereinafter referred to as "general frequency") for each Chinese character, but also frequency of use when used after a specific preceding character (hereinafter referred to as "specific frequency of use") It is also desirable to have a database of statistical information on). For example, although the general frequency of use of the Chinese character "安" is not superlative, the specific frequency of use of the Chinese character "安" when used after a certain preceding Chinese character such as "平" is superlative, for example.

In addition, the controller 400 controls the input unit 100, the display unit 200, and the memory unit 300 to operate the terminal 10 according to the present invention.

The Chinese character input method according to the present invention operating in the terminal having the above configuration will be described with reference to FIGS. 5 and 6.

5 is a schematic flowchart illustrating a kanji input method according to the present invention, and FIG. 6 is a view illustrating a display transition of the display unit when the kanji input method according to the present invention is executed.

It will be described below assuming that the terminal user has already input the "平" character in order to finally input the Chinese character "平安" ((610) of FIG. 6) and then wants to input the "安" character.

First, the terminal user inputs the structure of the input target Chinese character "安" in the standard stroke order as shown in 620 of FIG. 6 [S510]. Then, the second display unit 230 is displayed in the order of the input stroke, while the third display unit 250 is the Chinese characters corresponding to the order of the input strokes including the input target Chinese character "安" The list is displayed [S520, S530]. Then, when the terminal user selects "安" from the list using the navigation key 130 and the OK key 140 of the input unit 100 [S540], the input target Chinese character "安" is the first display unit. At 210, the input is displayed next to the "P" (630 of Figure 6).

By the way, it is assumed that the terminal user has made an error and inputs the input target kanji "安" into the input unit 100 in the wrong order as in the second display unit 230 of 640 of FIG. S510]. Then, the Chinese characters corresponding to the strokes in the wrong order are displayed on the third display unit 250 [S520]. Of course, since the strokes were input in the wrong order, the input target kanji "安" is not displayed on the third display unit 250.

Then, the user of the terminal recognizes that the input target Chinese character "安" is not displayed on the third display unit 250, and finds that there is an error in the order of the strokes input by the user [S530]. By pressing the first function key 110 (in the case of the automatic rearrangement method described later) or the second function key 120 (in the case of the manual rearrangement method described later), the arrangement input order is rearranged (S550). ].

The present invention proposes two rearrangement schemes as follows.

1) Automatic reordering method

The automatic reordering method uses a database 350 of Chinese character usage frequencies in the memory unit 300. That is, when the terminal user presses the first function key 110, the controller 400 refers to the database 350, and then enters the Chinese character “Phi” firstly input into the terminal. Which of the Chinese characters is used most frequently (that is, the specific frequency of use) is determined to be the highest, and the arrangement order of the second display unit 230 is rearranged according to the stroke order of the determined Chinese characters (FIG. 6). (650)) [S550].

In addition, the third display unit 250 displays a list of Chinese characters corresponding to the rearranged arrangement input order [S560], and if the terminal user has an input target Chinese character "安" among them, the navigation key 130 and OK are displayed. The key 140 is selected to be input to the first display unit 210 (660 of FIG. 6) [S530, S540].

If there is no input target Chinese character "安" in the list of Chinese characters corresponding to the rearranged input sequence, the terminal user again presses the first function key 110 so that the controller 400 is used next to the "Phi". Next, judge the next highest Chinese character and let the above procedure be repeated for the judged Chinese character.

In the above, the case in which the input target Chinese character "安" is input after the preceding Chinese character "平" has been described. However, if the input target kanji "安" is input for the first time without any preceding kanji, the controller 400 will perform the above-described procedure using the information on the general frequency of use of the database 350. . Since it will be easily understood from the foregoing description without detailed description, detailed description thereof will be omitted.

2) manual reordering

The manual rearrangement method does not require the user to delete the input stroke and input the stroke again in the correct stroke order when an error occurs in the Chinese character stroke input sequence as in the related art. Make it easy to rearrange.

That is, when the stroke of the input target kanji "安" is input in the wrong order as shown in 640 of FIG. 6, the terminal user performs the order on the second display unit 230 using the navigation key 130. The cursor is placed on the stroke to be moved (hereinafter referred to as "move target stroke") and the second function key 120 is pressed to select the target stroke to move. Next, the movement target stroke is moved again using the navigation key 130 as shown in 650 of FIG. 6 to rearrange the order of the input strokes [S550].

Then, the third display unit 250 displays a list of Chinese characters corresponding to the rearranged stroke order [S560], and if the terminal user has an input target Chinese character "安" among them, the navigation key 130 and the OK key are displayed. Selected using the reference numeral 140 to be input to the first display unit 210 (660 of FIG. 6) [S530, S540].

Thus, the terminal input of the Chinese character "平安" is completed.

It is apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit and essential features of the present invention. For example, it has been described above that the automatic rearrangement method and the manual rearrangement method are performed separately, but the two rearrangement methods may be configured to be performed in parallel. In addition, as described above, the present invention can be applied to all terminals capable of inputting Chinese-based languages (eg, Japanese) as well as terminals for Chinese.

Accordingly, the above detailed description should not be construed as limiting in all aspects and should be considered as illustrative. The scope of the present invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the present invention are included in the scope of the present invention.

Referring to the Chinese character input method according to the present invention described above and the effect of a mobile terminal that can implement the same as follows.

As described above, according to the present invention, even when an error is made in the kanji stroke order when the kanji is input by the stroke method, the user deletes the input stroke as before and inputs the stroke in the correct stroke order again. Rather, it is possible to easily rearrange the input stroke order automatically or manually, thereby making it easier to input Chinese characters in the terminal.
