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

detecting a user's gazing position; and

when the user's gazing position is spaced away from the position of the first touch input, displaying the first cursor at the user's gazing position.

8. The method according to claim 1 , further comprising;

detecting the movement of the first touch input on the first menu; and

when the first touch input is released, applying an item displayed at a position where the first touch input is released to the content.

9. The method according to claim 1 , further comprising displaying a sub menu of the item at the position of the first menu by a selection of an item on the first menu, wherein the first menu is a multi-level menu.

executing a shortcut that the text indicates in relation to the first menu.

14. The method according to claim 8 , further comprising, when there is an item applicable to the first menu at the user's gazing position, applying an item displayed at the position where the first input is released to an item of the user's gazing position.

15. A method of providing user interface, the method comprising:

detecting an input on a screen of an electronic device;

determining a user's gazing direction in response to the detected input while the input is being detected;

determining a function corresponding to the determined user's gazing direction;

performing the determined function;

when the user's gazing direction is toward the detected input, displaying, on the screen of the electronic device, a menu providing options for controlling an application that can be executed on the electronic device in the area of the detected input; and

when the user's gazing direction is spaced away from the area of the detected input, displaying a cursor in the user's gazing direction on the screen and activating a trackpad in the area of the detected input.

16. The method according to claim 15 , wherein detecting the input comprises:

determining whether the input is provided to a specified area of the screen of the electronic device;

when the input is provided to the specified area, determining the size of the input;

comparing the size of the input with a determined threshold; and
