Abstract

An input method for a mobile terminal with a touch screen is provided. The input method includes switching an operation mode of the mobile terminal to an input mode, and activating and displaying a virtual keypad; recognizing a specific key, from which a user input has occurred, among keys on the displayed virtual keypad; and displaying at least one or more functional objects designated to the recognized key, in a specific region of the virtual keypad.

Claims

1. An input method for a mobile terminal having a touch screen, comprising:

displaying a virtual keypad during an input mode;

recognizing a specific key activated on the displayed virtual keypad; and

displaying at least one or more functional objects corresponding to the recognized key in a predetermined region of the virtual keypad.

2. The input method of claim 1, wherein the functional objects displayed in the predetermined region is displayed in a same key layout as that of the virtual keypad.

3. The input method of claim 1, wherein any one object activated among the functional objects in the specific region is entered in an input field.

4. The input method of claim 1, wherein the recognized key is displayed on the virtual keypad in an active state until an input completion key is recognized.

5. The input method of claim 1, wherein the predetermined region of the virtual keypad further displays a character key adjacent to the recognized key.

6. The input method of claim 5, wherein the character key in the predetermined region is activated, the predetermined region is further changed to display at least one or more functional objects corresponding to the activated character key.

7. The input method of claim 1, wherein the virtual keypad has a QWERTY key layout.

8. An input apparatus for a mobile terminal having a touch screen, comprising:

a virtual keypad having a plurality of virtual keys, each of the virtual keys having at least one or more functional objects corresponding thereto;

a display displaying the virtual keypad and including an input field for displaying a character activated on the virtual keypad; and

a controller configured to recognize a specific key activated on the virtual keypad and to display at least one or more functional objects corresponding to the recognized key in a predetermined region of the virtual keypad.

9. The input apparatus of claim 8, wherein the controller controls any one object selected activated in the specific region to be entered in the input field for display.

10. The input apparatus of claim 8, wherein the one or more functional objects include numbers, language-specific characters, symbols, and special characters.

11. The input apparatus of claim 8, wherein the controller is configured to display a key adjacent to the recognized key in the specific region of the virtual keypad.

12. The input apparatus of claim 11, wherein the controller controls such that when the key adjacent to the recognized key displayed in the predetermined region is activated, the predetermined region is further changed to display at least one or more functional objects corresponding to the activated key.

13. A mobile terminal having a touch screen, comprising:

a display displaying a virtual keypad having a plurality of virtual keys, each of the virtual keys having at least one or more functional objects corresponding thereto; and

a controller recognizing a specific key activated on the virtual keypad and to display at least one or more functional objects corresponding to the recognized key in a predetermined region of the virtual keypad.

14. The mobile terminal of claim 13, wherein the display further displaying an input field for displaying a character activated on the virtual keypad and on the predetermined region.

15. The mobile terminal of claim 13, wherein the one or more functional objects include numbers, language-specific characters, symbols, and special characters.

16. The mobile terminal of claim 13, wherein the controller displays a key adjacent to the recognized key in the specific region of the virtual keypad.

17. The mobile terminal of claim 14, wherein the controller further changes the predetermined region to display at least one or more functional objects corresponding to the key when the key adjacent to the recognized key displayed in the specific region of the virtual keypad is activated.
