Abstract

A mobile terminal and a method for controlling the same are disclosed, where symbols used often when inputting characters and pointer position moving are input simultaneously by using a touch gesture of a user, such that character input may be accelerated.

Claims

1. A mobile terminal, comprising:

a touchscreen configured to;

display a keypad including a plurality of character keys and functional keys, and

display a text box separate from the keypad;

a memory configured to;

store a first symbol, a plurality of different first touch gestures, and a first functional key mapped with each other, and

store a second symbol, a plurality of different second touch gestures, and a second functional key mapped with each other; and

a controller configured to;

map a different first operation for each first touch gesture made on the first functional key of the keypad, and

map a different second operation for each second touch gesture made on the second functional key of the keypad,

the first operation being one of

displaying a first symbol mapped to a detected first touch gesture and the first functional key at a position of a pointer displayed in the text box on the touchscreen, followed by a move of the pointer, and

moving the pointer displayed in the text box in a direction mapped to the detected first touch gesture and the first functional key,

the second operation being one of

displaying a second symbol mapped to a detected second touch gesture and the second functional key at the position of the pointer displayed in the text box on the touchscreen, followed by the move of the pointer, and

moving the pointer displayed in the text box in a direction mapped to the detected second touch gesture and the second functional key.

2. The mobile terminal of claim 1, wherein each of the detected first and second touch gestures is preset by a user.

3. The mobile terminal of claim 1, wherein the controller is configured to display at least one menu for setting each touch gesture, the first and second functional keys of the keypad, and the first and second symbols mapped to the detected first and second touch gestures and the first and second functional keys.

4. The mobile terminal of claim 1, wherein the first and second detected touch gestures further include one of:

a drag contact or proximity touch,

a flicking contact or proximity touch having a predetermined direction,

a long touch for a predetermined time period,

a multi touch touching two points on the screen, and

a combination of different touches or contacts.

5. The mobile terminal of claim 1, wherein the symbol is a punctuation mark.

6. The mobile terminal of claim 5, wherein the punctuation mark is one of a comma, a period, an exclamation mark, a quotation mark, a parenthesis mark, an asterix, an ampersand, a colon, a semi-colon, a brace, a bracket, a currency mark, an “

at”

symbol, a hyphen, a forward slash, a backward slash, and a mathematical symbol.

7. The mobile terminal of claim 1, wherein each of the directions mapped to the first and second touch gestures and the first and second functional keys, respectively, is one of a backspace, a forward space, a move to a next line, a move to a previous line, and a tab.

8. The mobile terminal of claim 1, wherein the move of the pointer is one of a backspace, a forward space, a move to a previous line, and a tab.

18. The mobile terminal of claim 1, wherein each of the detected first and second touch gestures is in a plane of the touchscreen or in a plane parallel to the plane of the touchscreen.

19. The mobile terminal of claim 1, wherein the first symbol and the plurality of different first touch gestures are mapped with the first functional key, not the other functional keys including the second functional key, and the second symbol and the plurality of different second touch gestures are mapped with the second functional key, not the other functional keys including the first functional key.

9. A method of controlling a mobile terminal having a touchscreen and a controller, the method comprising:

displaying, by the touchscreen, a keypad including a plurality of character keys and functional keys;

displaying, by the touchscreen, a text box separate from the keypad;

storing, by a memory in the mobile terminal, a first symbol, a plurality of different first touch gestures, and a first functional key mapped with each other;

storing, by the memory, a second symbol, a plurality of different second touch gestures, and a second functional key mapped with each other;

mapping, by a controller in the mobile terminal, a different first operation for each first touch gesture made on the first functional key of the keypad; and

mapping, by the controller, a different second operation for each second touch gesture made on the second functional key of the keypad;

wherein the first operation is one of

displaying a first symbol mapped to the detected first touch gesture and the first functional key at a position of a pointer displayed in the text box on the touchscreen, followed by a move of the pointer, and

moving the pointer displayed in the text box in a direction mapped to the detected first touch gesture and the first functional key, and

wherein the second operation is one of

displaying a second symbol mapped to a detected second touch gesture and the second functional key at the position of the pointer displayed in the text box on the touchscreen, followed by the move of the pointer, and

moving the pointer displayed in the text box in a direction mapped to the detected second touch gesture and the second functional key.

10. The method of claim 9, wherein each of the detected first and second touch gestures is preset by a user.

11. The method of claim 9, further comprising:

displaying at least one menu for setting each touch gesture, the first and second functional keys of the keypad, and the first and second symbols mapped to the detected first and second touch gestures and the first and second functional keys.

12. The method of claim 9, wherein the first and second detected touch gestures further include one of:

a drag contact or proximity touch,

a flicking contact or proximity touch having a predetermined direction,

a long touch for a predetermined time period,

a multi touch touching two points on the screen, and

a combination of different touches or contacts.

13. The method of claim 9, wherein the symbol is a punctuation mark.

14. The method of claim 13, wherein the punctuation mark is one of a comma, a period, an exclamation mark, a quotation mark, a parenthesis mark, an asterix, an ampersand, a colon, a semi-colon, a brace, a bracket, a currency mark, an “

at”

symbol, a hyphen, a forward slash, a backward slash, and a mathematical symbol.

15. The method of claim 9, wherein each of the directions mapped to the detected first and second touch gestures and the first and second functional keys, respectively, is one of a backspace, a forward space, a move to a next line, a move to a previous line, and a tab.

16. The method of claim 9, wherein the move of the pointer is one of a backspace, a forward space, a move to a next line, a move to a previous line, and a tab.

17. The method of claim 9, wherein each of the detected first and second touch gestures is in a plane of the touchscreen or in a plane parallel to the plane of the touchscreen.
