For example, the first jog key 110 detects a motion and outputs first trace data of Korean consonants. In addition, the first jog key 110 receives the push data in response to a user's manipulation signal.

The second jog key 120 may detect the movement according to a manipulation signal of the user and output second trace data. In particular, the second jog key 120 detects a movement and outputs second trace data for numbers, Korean vowels, and English letters. In addition, of course, the second jog key 120 may output the push data according to a user's manipulation signal.

Here, in the field of manufacturing a portable terminal, a technology for installing such a jog key in a portable terminal is known, and those skilled in the art can implement such a jog key from the contents described herein.

The data determination unit 130 determines whether the data input from the first jog key 110 and the second jog key 120 is trace data or push data, and transmits the determination result to the character detection unit 150.

The storage 140 stores programs and data necessary for the operation and status of the portable terminal 100 or the control of the controller 160. In addition, the storage 140 may use various volatile / nonvolatile memory devices. In particular, the storage unit 140 stores the printed text data corresponding to the handwritten text data.

The character detector 150 receives one of the first trace data and the second trace data and detects text data corresponding to the received trace data. The character detector 150 includes a generator 151, a searcher 153, and a combiner 155.

The generation unit 151 receives one of the first trace data and the second trace data, and combines the received trace data to generate handwritten text data.

The search unit 153 retrieves the printed character data corresponding to the generated handwritten character data from the storage 140 and transmits the retrieved printed character data to the combiner 155.

The combiner 155 determines whether the print character data retrieved from the searcher 153 can be combined with the previously displayed print character data, and performs character combining. For example, the combination unit 155 determines that the displayed print text data is 'a' and the print text data retrieved from the search unit 153 is 'ㅏ', and thus displays the print text data. On the other hand, when the displayed print character data is 'ㅋ' and the print character data retrieved from the search unit 153 is 'ㅋ', the combiner 155 determines that it is not possible to combine and separates the print character data as 'ㅋ ㅋ'. To display.

When the push data of the first jog key 110 and the trace data of the second jog key 120 are generated at the same time, the character detector 150 detects handwritten character data that is a number corresponding to the second trace data. Meanwhile, when the push data of the second jog key 120 and the trace data of the first jog key 110 are generated at the same time, the character detector 150 may detect the character data that is a number corresponding to the first trace data. Of course.

When the second trace data of the second jog key 120 is generated after the press data of the first jog key 110 is generated, the character detector 150 changes the character input mode under the control of the controller 160. Next, the character detector 150 detects the handwritten character data corresponding to the second trace data in accordance with the changed character input mode.

The controller 160 controls the overall state and operation of the character input device 100. For example, it may be made of a microprocessor. In particular, when the push data of the first jog key 110 is generated by the user's operation signal, the controller 160 changes the character input mode. For example, when the push data of the first jog key 110 is generated, the controller 160 changes the character input mode from uppercase English letters to lowercase English letters. In addition, it is of course possible to change the character input mode from lowercase letters to uppercase letters.

The display unit 170 displays a state and an operation process of the character input device 100. The operation state and a plurality of pieces of information of the text input device 100 are displayed with icons and text. In particular, the display unit 170 displays the printed character data retrieved from the character detection unit 150 under control of the control unit 160.

4 is a flowchart sequentially illustrating a character input method according to an embodiment of the present invention. Before describing FIG. 4, a method for inputting a character of the character input apparatus 100 according to the present invention will be briefly described with reference to Table 1 below.

First jog key generation data 21 Second jog key generation data (23) Display character (25) First trace data x Hangul consonants x Second trace data English (large / small) / Hangul collection Simultaneous Press Data Second trace data number Push data Second trace data English letter (large / small)

Referring to Table 1, when the first trace data is generated from the first jog key 110, the Hangul consonants according to the first trace data are displayed. When the second trace data is generated from the second jog key 120, alphabetic characters (large / small) or Korean vowels according to the second trace data are displayed.

In addition, when the push data of the first jog key 110 and the second trace data of the second jog key 120 are generated at the same time, a number corresponding to the second trace data of the second jog key 120 is displayed. When the second trace data of the second jog key 120 is generated after the pressing data of the first jog key 110 is generated, an English letter corresponding to the second trace data of the second jog key 120 is displayed. At this time, if the character input mode before the press data generation of the first jog key 110 is uppercase English letter, the character input mode is changed to lowercase English letter after the press data generation, and if the character input mode before the press data generation is lowercase English letter, press After the data is generated, it is changed to English capital letters.

3 and 4, the controller 160 determines whether a user manipulation signal is input to the first jog key 110 while operating in a text input mode (S200). When the first jog key 110 has a user manipulation signal input, the controller 160 controls the data determination unit 130 to determine whether the data generated by the manipulation signal of the user is first trace data or pressed data, The determination result is transmitted to the character detection unit 150 (S220). If the generated data is determined to be the first trace data, the controller 160 controls to display the first trace data as text data (S230). A detailed description of the S230 process is made with reference to FIG. 5. In FIG. 5, the trace data may be first trace data.

Referring to FIG. 5, the controller 160 controls the generation unit 151 to generate handwritten character data by combining the input trace data in order (S231). The controller 160 retrieves the printed character data corresponding to the handwritten character data generated by controlling the searcher 153 from the storage 140 and outputs a search result (S232). The controller 160 controls the search unit 153 to determine whether there is printed text data from the search result output (S233). If the print text data exists, the controller 160 controls the search unit 153 to select the searched print text data (S234). The controller 160 controls the combiner 155 to determine whether the selected print character data and the previously displayed print character data can be combined (S235). At this time, if the previously displayed print text data does not exist, the controller 160 displays the selected print text data on the display unit 170.

As a result of the above-described determination in step S235, when the combination is possible, the controller 160 controls the combiner 155 to combine the previously displayed printed text data with the selected printed text data on the display unit 170 (S236). For example, when the Hangul consonant 'ㄱ', which is the print character data, is displayed in advance, and the print character data corresponding to the handwritten character data generated from the input trace data is the Hangul vowel 'ㅏ', the combining unit 155 may include: The two character data are combined and displayed on the display unit 170 as 'a'.

On the other hand, if it is determined that the combination is not possible, the controller 160 controls the combiner 155 to separate the previously displayed print text data and the selected print text data and display them on the display unit 170 (S237). For example, when the lowercase letter 'a', which is the print character data, is displayed in advance, and the print character data corresponding to the cursive character data generated from the input trace data is the lowercase letter 'b', the combining unit 155 may include: The two character data are separated and displayed on the display unit 170 as 'ab'.

Referring back to FIG. 4, if the data generated as a result of the above-described S220 process is not the first trace data, the controller 160 determines the generated data by controlling the data determination unit 130 as push data (S240).

The controller 160 determines whether there is an input of a user manipulation signal to the second jog key 120 (S250). When the second jog key 120 has a user manipulation signal input, the controller 160 controls the data determination unit 130 to determine whether the data generated by the manipulation signal of the user is the second trace data, and determines the determination result. The character detection unit 150 transmits (S260). If it is determined that the generated data is the second trace data, the controller 160 checks whether or not the push data has been generated in step S220 (S270). If the push data has not occurred in the above-described step S220, the controller 160 displays the text data according to the second trace data (S280). Since the process S280 is the same as the process S230 described above with reference to FIG. 5, a description thereof will be omitted. In this case, the trace data in FIG. 5 is preferably second trace data.

If the press data is generated in the above-described step S220, the controller 160 controls to display the text data according to the press data (S290). A detailed description of the S290 process will be described with reference to FIG. 6.

Referring to FIG. 6, the controller 160 controls the character detector 150 to determine whether the push data of the first jog key 110 and the second trace data of the second jog key 120 are generated at the same time. (S291). If the push data and the second trace data are generated at the same time, the controller 160 controls the generation unit 151 to generate handwritten character data that is a number corresponding to the second trace data, and controls the search unit 153 to generate them. The printed character data corresponding to the one handwritten character data is retrieved and displayed on the display unit 170 (S293).

On the other hand, if the push data and the second trace data do not occur at the same time, the controller 160 changes the character input mode (S295). For example, if the character input mode before the press data generation is the English uppercase mode, the character input mode after the press data generation is changed to the lowercase English mode.

The controller 160 displays character data corresponding to an English letter corresponding to the second trace data according to the character input mode changed by the above-described step S295 (S297). Process S297 is the same as the above-described process S230 and S280, and a description thereof will be omitted. At this time, the trace data of the step S297 is preferably the second trace data.

In the above, specific preferred embodiments of the present invention have been illustrated and described. However, the present invention is not limited to the above-described embodiment, and various modifications can be made by those skilled in the art without departing from the gist of the present invention attached to the claims. will be.

According to the present invention, a character can be quickly inputted without memorizing the keyboard of the keypad. In addition, users with poor eyesight can enter characters intuitively by using two jog keys without having to check the keypad on the keyboard.
