Abstract

A method of creating an electronic document in a mobile terminal is provided. The method includes displaying an electronic document screen, sensing a hover-in event of an input unit when the electronic document screen is displayed, enlarging a size of the electronic document screen in response to the hover-in event of the input unit, creating the electronic document according to a user input on the enlarged electronic document screen, sensing a hover-out event of the input unit when the enlarged electronic document is displayed, and reducing a size of the enlarged electronic document screen in response to the hover-out event of the input unit.

Claims

1. A method of creating an electronic document in a mobile terminal, the method comprising:

displaying an electronic document screen;

sensing a hover-in event of an input unit when the electronic document screen is displayed;

determining an enlargement ratio of the electronic document screen according to a type of the input unit that performs the hover-in event;

enlarging a size of the electronic document screen in response to the determined enlargement ratio;

receiving touch-based writing data by the input unit in a state where the enlarged electronic document screen is maintained;

displaying the received touch-based writing data by a size corresponding to the determined enlargement ratio according to a movement of the input unit on the enlarged electronic document screen when the electronic document screen is enlarged;

in response to a hover-out event of the input unit, reducing the size of the enlarged electronic document screen; and

reducing a display of the touch-based writing data displayed by a size corresponding to a reduction ratio of the electronic document when reducing the enlarged electronic document screen.

2. The method according to claim 1, wherein the enlarging of the size of the electronic document screen comprises:

enlarging the electronic document screen around a coordinate value of the input unit that performs the hover-in event.

3. The method according to claim 1, further comprising:

moving the screen according to a user input on the enlarged electronic document screen.

4. The method according to claim 3, wherein the moving of the screen includes moving the screen by any one of a drag input method, a touch-based long press input method, a hovering input method, a selection input method on a direction indicating item, and a hovering input method over the direction indicating item.

5. An apparatus for creating an electronic document in a mobile terminal, the apparatus comprising:

a display unit configured to display an electronic document screen;

a touch sensor configured to;

detect a user input when the electronic document screen is displayed, and

sense a hover-in or a hover out event of an input unit when the electronic document screen is displayed; and

a controller configured to;

determine an enlargement ratio of the electronic document screen according to a type of the input unit that performs the hover-in event;

enlarge a size of the electronic document screen in response to the determined enlargement ratio;

receive touch-based writing data by the input unit in a state where the enlarged electronic document screen is maintained;

display the received touch-based writing data by a size corresponding to the determined enlargement ratio according to a movement of the input unit on the enlarged electronic document screen when the electronic document screen is enlarged;

in response to a hover-out event of the input unit, reduce the size of the enlarged electronic document screen; and

reduce a display of the touch-based writing data displayed by a size corresponding to a reduction ratio of the electronic document when reducing the enlarged electronic document screen.

6. The apparatus according to claim 5, wherein the controller is further configured to enlarge the electronic document screen around a coordinate value of the input unit that performs the hover-in event.

7. The apparatus according to claim 5, wherein the controller is further configured to move the screen according to a user input on the enlarged electronic document screen.

8. The apparatus according to claim 7, wherein the controller is further configured to move the screen by any one of a drag input method, a touch-based long press input method, a hovering input method, a selection input method on a direction indicating item, and a hovering input method over the direction indicating item.

9. The apparatus according to claim 5, wherein the hover-in event comprises:

an input in which the input unit is moved in to a certain height over the electronic document screen and the electronic document screen is resized according to a resize ratio for each type of input unit.

10. The apparatus according to claim 5,

wherein the hover-out event comprises an input in which the input unit is moved out a certain height over the electronic document screen, and

wherein the resized electronic document screen is displayed to a full screen.
