wherein the step of displaying the sub menu icon includes

confirming whether a movement area of the second touch exists within an enlarged menu element area,

confirming whether a movement speed of the second touch exists within a range between a first reference speed and a second reference speed when the movement area of the second touch exists within the enlarged menu element area,

determining a sub menu icon display speed value based on the movement speed of the second touch when the movement speed of the second touch exists within the range between the first reference speed and the second reference speed, and

displaying the sub menu icon based on the determined sub menu icon display speed value while displaying the untouched menu element of the displayed plurality of menu elements but not displaying a sub menu icon corresponding to the untouched menu element of the displayed plurality of menu elements,

wherein the second touch characteristic is a direction of the second touch,

wherein the direction of the second touch comprises one of a first direction, a second direction and a third direction,

wherein the first direction, the second direction and the third direction are different from each other, and

wherein

when the direction of the second touch is the first direction, the sub menu icon only represents a sub menu element that was most frequently selected by a user,

when the direction of the second touch is the second direction, the sub menu icon only represents a sub menu element that was most recently selected by the user, and

when the direction of the second touch is the third direction, the sub menu icon only represents a sub menu element that was previously selected as a favorite sub menu element.

2. The user interface method of claim 1, wherein

the sub menu icon is one of a plurality of sub menu icons associated with the touched menu element, and

the step of displaying the sub menu icon includes selecting the sub menu icon from the plurality of sub menu icons based on the second touch characteristic.

3. The user interface method of claim 1, further comprising:

detecting an additional touch over the sub menu icon, including detecting an additional touch characteristic; and

displaying, within the touched menu element area and in response to the additional touch characteristic, a second sub menu icon, the second sub menu icon being associated with the touched sub menu icon.

4. The user interface method of claim 3, wherein the additional touch characteristic and the second touch characteristic are common touch characteristics.

5. The user interface method of claim 3, wherein the additional touch characteristic is different from the second touch characteristic.

6. The user interface method of claim 1,

wherein the second touch characteristic is a flicking motion, and

wherein the step of displaying the sub menu icon includes scrolling the touched menu element and the sub menu icon in a direction of the flicking motion while not scrolling the untouched menu element of the displayed plurality of menu elements or the corresponding untouched menu element sub menu icon such that a portion of the touched menu element and a portion of the sub menu icon are displayed in the corresponding menu element area while the menu element is scrolled.

7. The user interface method of claim 6, further comprising:

detecting an additional touch over the sub menu icon, including detecting an additional touch characteristic; and

one of

displaying, within the menu and in response to the additional touch characteristic, a second sub menu icon, the second sub menu icon being associated with the additionally touched sub menu icon, and

executing a function associated with the additionally touched sub menu icon.

8. The user interface method of claim 6,

wherein the movement speed of the second touch is a detected speed of the flicking motion, and

wherein the step of scrolling includes scrolling with a speed correlated to the detected speed of the flicking motion.

9. The user interface method of claim 1, the step of displaying the sub menu icon associated with the touched menu element comprising:

replacing the touched menu element within the displayed menu with the sub menu icon.

10. The user interface method of claim 1, the step of displaying the sub menu icon associated with the touched menu element comprising:

displaying the sub menu icon in an area substantially adjacent to the touched menu element within the displayed menu.

11. The user interface method of claim 1, the step of displaying the sub menu icon associated with the touched menu element comprising:

superimposing the sub menu icon over at least a portion of the touched menu element.

12. The user interface method of claim 1, the step of displaying the sub menu icon associated with the touched menu element comprising:

displaying the sub menu icon without displaying a sub menu corresponding to the touched menu element.

13. The user interface method of claim 1, further comprising:

displaying the sub menu icon without activating or executing the touched menu element.

14. The user interface method of claim 1, wherein the menu is a home menu.

15. The user interface method of claim 1, wherein the sub menu icon is one of an executable sub menu icon and a non executable sub menu icon.

16. The user interface method of claim 1, wherein the sub menu icon is an executable sub menu icon, the method further comprising:

detecting an additional touch over the sub menu icon; and

automatically executing an application associated with the touched sub menu icon.

22. The user interface method of claim 1,

wherein the second touch characteristic is a flicking motion,

wherein the step of displaying the sub menu icon includes scrolling the touched menu element and the sub menu icon in a direction of the flicking motion while not scrolling the untouched menu element of the displayed plurality of menu elements or the corresponding untouched menu element sub menu icon.

17. An apparatus, comprising:
