The touch screen 810 displays a touch key by a combination of a basic key set or a basic key set and an extended key set under the control of the controller 850 and displays a character corresponding to the key input through the touch key on the display unit .

When the user touches or touches a specific key of the touch keyboard displayed on the touch screen 810 with a pointer, the input sensing unit 830 determines that the pointer is not dragged and dropped If the pointer is dragged in a specific area without releasing the pointer for a predetermined time, the controller 850 detects the input of the specific key and inputs the key to the controller 850.

The control unit 850 controls the display unit 810 to display a character corresponding to the received key or a combination thereof on a touch keyboard and / or a display area of the touch screen 810, Is displayed on the display unit of the display unit (810). That is, the control unit 850 initially displays the basic key set and controls the touch screen 810 to display the extended key set on the basic key set when the character corresponding to the key input from the basic key set is consonant. Hereinafter, referring to FIG. 9, it is assumed that the character input (character input) according to the embodiment of the present invention performed by the control unit 850 The method will be described.

9 is a flowchart illustrating a method of inputting a character using a touch keyboard according to an embodiment of the present invention.

Referring to FIG. 9, in step 901, the controller 850 controls the touch screen 810 to display a basic key set or a combination of a basic key set and an extended key set, and waits for a key input by the user.

In step 903, the control unit 850 receives the detection result of the specific key displayed on the touch screen 810 by the input sensing unit 830, and confirms the key input through the basic key set or the extended key set. At this time, the detection result indicates whether the specific key is touched by a pointer, whether the pointer has been dragged and dropped after the touch has been held for a predetermined time, whether the pointer has been dragged in a specific area without releasing the pointer for a predetermined time .

In step 905, the controller 850 determines whether the input key is a character. If the input key is a character, the process proceeds to step 909. Otherwise, the control unit 850 proceeds to step 907 to perform a corresponding operation on the input key.

In step 909, the control unit 850 determines whether a character corresponding to the input key can be combined with a character corresponding to a previously input key. If the character corresponds to the input key, (I.e., when there is no previously input key), a character corresponding to the key input is displayed on the touch screen 810. In this case, (810).

For example, in the case of Chinese input, the control unit 850 checks whether the character corresponding to the input key is combined with the character corresponding to the previously input key, and if the result is a Chinese Pinyin, The corresponding Chinese character can be confirmed by a character to be displayed on the touch screen 810. [ Also, in the case of Chinese input, the controller 850 may short-drag the pointer touched in C, S, Z in a specific area (i.e., within the area of each C key, S key, and Z key) (Ch, Sh, Zh) obtained by combining the characters corresponding to the input key by h is confirmed as a character to be displayed on the touch screen 810. In addition, If the result of the detection indicates that the user has dragged the pointer touched in the u key of the extended keyset in a specific area (i.e., within the area of the U key), the controller 850 may display the character Check.

In step 911, the controller 850 controls the displayed character to be displayed on the touch screen 810.

In step 913, the control unit 850 determines whether the character for the input key is input in the basic key set. If the input key is input in the basic key set, the controller 850 proceeds to step 915 to display the extended key set for the input key. If it is not input in the keyset (that is, if it is input in the extended keyset), the process proceeds to step 917 to determine whether or not to change the previously displayed extended keyset.

In step 915, the controller 850 controls the touch screen 810 to display the extended keyset for the input key in an overlapped manner with the input key, and then proceeds to step 901 to wait for a key input by the user . If the extended keyset for the previously input key is present on the touch keyboard, the control unit 850 removes the extended keyset for the previously input key to include only the extended keyset for the currently input key And controls the touch screen 810 to display the touch keyboard.

 If it is inputted in the extended key set, the control unit 850 determines whether the extended key set is changed or not in step 917. If the extended key set is changed, the extended key set is changed in step 1021, It proceeds to step 901 and waits for the user to input a key.
