Abstract

A method of inputting text in an electronic device having a touch screen is provided. The method includes displaying a screen including a keypad and a character input window, displaying a recommended text related to a character on a candidate window when an input of the character is detected through the keypad, detecting a gesture of a touch input according to the recommended text, and displaying a recommended text to which a style corresponding to the gesture is applied on the character input window.

Claims

1. A method of inputting text in an electronic device comprising a touch screen, the method comprising:

displaying a screen including a keypad and a character input window;

displaying a recommended text related to a character on a candidate window when an input of the character is detected through the keypad;

detecting a gesture of a touch input according to the recommended text; and

displaying a recommended text to which a style corresponding to the gesture is applied on the character input window.

2. The method of claim 1, wherein it is determined whether the gesture comprises one of a tap and a drag,

wherein if the gesture comprises the drag then the style is determined according to a direction of the drag, and

wherein if the gesture comprises the tap then a tapped recommended text is displayed according to one or more style candidates on a candidate window.

3. The method of claim 2, wherein if the gesture comprises a single horizontal drag, then the style comprises an underline,

wherein if the gesture comprises a back and forth horizontal drag, then the style comprises a boldface,

wherein if the gesture comprises a diagonal drag, then the style comprises an inclination, and

wherein if the drag comprises a vertical direction, then the style comprises adjusting a text size according to the drag.

4. The method of claim 3, wherein if the vertical drag is maintained for a threshold period of time, a text size adjustment tool is displayed.

5. The method of claim 1, wherein the displaying of the recommended text on the character input window comprises displaying a text to which a style corresponding to a moving direction of the gesture is applied.

6. The method of claim 1, further comprising, after the detecting of the gesture of the touch input:

displaying a style candidate group, on the candidate window, corresponding to the gesture; and

detecting a selection of one style from the style candidate group.

7. The method of claim 5, wherein the style comprises at least one among a font type, a character size, a character color and an attribute.

8. The method of claim 7, wherein the displaying of the recommended text on the character input window comprises displaying the keypad with the detected style applied to characters thereon.

9. The method of claim 1, wherein the displaying of the screen comprises displaying a sentence style candidate group on the candidate window when a cursor is displayed on the character input window.

10. An electronic device comprising:

a touch screen configured to detect a gesture of a touch input and to display a character input window and a keypad; and

a controller configured to control the touch screen,

wherein the controller detects an input of a character through the keypad, controls a recommended text related to the character to be displayed on a candidate window, detects a gesture of a touch input according to the recommended text, and controls a text, to which a style corresponding to the gesture is applied, to be displayed on the character input window.

11. The electronic device of claim 10,

wherein it is determined whether the gesture comprises one of a tap and a drag,

wherein if the gesture comprises the drag then the style is determined according to a direction of the drag, and

wherein if the gesture comprises the tap then a tapped recommended text is displayed according to one or more style candidates on a candidate window.

12. The electronic device of claim 11, wherein if the gesture comprises a single horizontal drag, then the style comprises an underline, wherein if the gesture comprises a back and forth horizontal drag, then the style comprises a boldface, wherein if the gesture comprises a diagonal drag, then the style comprises an inclination, and wherein if the drag comprises a vertical direction, then the style comprises adjusting a text size according to the drag.

13. The electronic device of claim 12, wherein if the vertical drag is maintained for a threshold period of time, a text size adjustment tool is displayed.

14. The electronic device of claim 10, wherein the controller controls a text, to which a style corresponding to a moving direction of the gesture is applied, to be displayed on the character input window.

15. The electronic device of claim 10, wherein the controller controls a style candidate group to be displayed on the candidate window in response to the gesture and detects a selection of one style from the style candidate group.

16. The electronic device of claim 15, wherein the style comprises at least one among a font type, a character size, a character color, and an attribute.

17. The electronic device of claim 16, wherein the controller controls the keypad to be displayed with the detected style applied to characters thereon.

18. The electronic device of claim 10, wherein the controller controls a sentence style candidate group to be displayed when a cursor is displayed on the character input window.
