Abstract

A mobile terminal is provided. The mobile terminal includes a touch screen for generating input signals in response to a proximity touch or a direct touch of an input medium and displaying a first menu and a controller for determining the proximity touch of the input medium on the touch screen for a predetermined period of time and displaying on the touch screen a second menu for providing a function associated with the first menu.

Claims

1. A method for providing a graphic user interface using a mobile terminal, the method comprising:

sensing a proximity touch over an input window displayed on a touch screen;

determining a duration of time of the sensed proximity touch;

displaying a most frequently input identifier in the input window when the determined duration of time is greater than or equal to a predetermined duration of time;

sensing a proximity gesture over the input window in which the most frequently input identifier is displayed, concurrent with the sensed proximity touch;

in response to sensing the proximity gesture, ceasing the display of the most frequently input identifier and displaying a next most frequently input identifier in the input window; and

ceasing the display of at least the most frequently input identifier or the next most frequently input identifier when the sensed proximity touch subsequently deviates from a touch recognition distance relative to the touch screen without a direct touch being received.

2. The method of claim 1, further comprising:

determining that the direct touch is received on at least the display of the most frequently input identifier or the display of the next most frequently input identifier; and

executing a function associated with the most frequently input identifier if it is determined that the direct touch is received on the display of the most frequently input identifier; and

executing a function associated with the next most frequently input identifier if it is determined that the direct touch is received on the display of the next most frequently input identifier.

3. A mobile terminal comprising:

a touch screen configured to;

display an input window;

a sensing unit configured to;

sense a proximity touch over the input window, and

sense a direct touch to the input window; and

a controller configured to;

determine that the proximity touch occurred for a predetermined period of time,

control the touch screen to display a most frequently input identifier in the input window in response to determining that the proximity touch occurred for the predetermined period of time, wherein the most frequently input identifier is associated with the input window,

sense a proximity gesture over the input window in which the most frequently input identifier is displayed, concurrent with the sensed proximity touch,

in response to sensing the proximity gesture, cease the display of the most frequently input identifier and display a next most frequently input identifier in the input window, wherein the next most frequently input identifier is associated with the input window,

determine whether the direct touch occurred to the input window in which at least the most frequently input identifier or the next most frequently input identifier is displayed, and

control the touch screen to cease the display of at least the most frequently input identifier or the next most frequently input identifier when an input medium performing the proximity touch deviates from a touch recognition distance relative to the touch screen without the direct touch being sensed.
