Abstract

Disclosed are a method and an apparatus for providing a user interface. The apparatus for providing a user interface, includes a controller operating such that a lock image with respect to at least a partial user interface and an object for changing a lock state to a release state are displayed on a screen, and a touch sensor sensing a first contact of a touch gesture on the object, wherein the controller determines a distance between the object and a second contact of the touch gesture with respect to the first contact on the object, and changes the lock state to the release state and the removes the lock image from the screen when the distance between the object and the second contact of the touch gesture is greater than a preset threshold.

Claims

1. A method of providing a user interface, the method comprising:

displaying on a screen a lock image with respect to at least a partial user interface and an object for changing a lock state to a release state;

sensing a first contact of a touch gesture on the object;

determining a distance between the object and a second contact of the touch gesture in response to the first contact on the object; and

changing the lock state to the release state and removing the lock image from the screen when the distance between the object and the second contact is greater than a preset threshold.

2. The method of claim 1, further comprising:

displaying an object-set including at least one touch-on object and determining a distance between the object and a third contact of the touch gesture in response to the first contact on the object; and

when the distance between the object and a third contact of the touch gesture is commensurate with one of at least one touch-on distances, applying a visual effect corresponding to the commensurate touch-on distance to the object-set to display the applied visual effect on the screen.

3. An apparatus for providing a user interface, the apparatus comprising:

a controller controlling a display on a screen of a lock image with respect to at least a partial user interface and an object for changing a lock state to a release state; and

a touch sensor sensing a first contact of a touch gesture on the object,

wherein the controller determines a distance between the object and a second contact of the touch gesture in response to the first contact on the object, and

changes the lock state to the release state and removes the lock image from the screen when the distance between the object and the second contact is greater than a preset threshold.

4. The apparatus of claim 3, wherein the controller:

displays an object-set including at least one touch-on object;

determines a distance between the object and a third contact of the touch gesture in response to the first contact on the object; and

applies a visual effect corresponding to a commensurate touch-on distance to the object-set such that the applied visual effect is displayed on the screen when the distance between the object and the third contact of the touch gesture accords with one of the at least one touch-on distances.

5. A method of providing a user interface, the method comprising:

displaying on a screen a lock image with respect to at least a partial user interface and an object for changing a lock state to a release state;

sensing a first contact of a touch gesture on the object;

activating a virtual preset touch line having a looped curve shape surrounding the object in response to the first contact on the object; and

changing the lock state to the release state and removing the lock image from the screen when a second contact of the touch gesture is located in an area outside of the virtual preset touch line.

6. The method of claim 5, further comprising:

activating at least one virtual touch guide line with a preset location in response to the first contact;

maintaining mapping information between the at least one virtual touch guide line and at least one visual effect in a memory; and

when the touch gesture contacts one of the at least one virtual touch guide lines, displaying a visual effect corresponding to the contacted virtual touch guide line.

7. The method of claim 6, wherein the visual effect corresponding to the contacted virtual touch guide line is one of cases where an object-set, including at least one touch-on object arranged one or on and around the contacted virtual touch guide lineappears and disappears.

8. The method of claim 6, wherein the visual effect corresponding to the contacted virtual touch guide line is at least one of a transparency, a color, a luminance, a brightness, a size, a shape, a rotating angle, and a location of an object-set.

9. The method of claim 5, further comprising:

displaying an object-set with at least one touch-on object;

activating at least one virtual touch guide line with a preset location in response to the first contact; and

when the touch gesture contacts one of the at least one virtual touch guide lines, applying a visual effect corresponding to the virtual contacted touch guide line to the object-set to display the applied visual effect on the screen.

10. The method of claim 5, wherein activating a virtual preset touch line comprises:

detecting a distance between the object and the second contact of the touch gesture when the virtual preset touch line is a circle having a center on the object; and

determining whether the distance between the object and the second contact of the touch gesture is greater than a radius of the virtual preset touch line.

11. The method of claim 5, further comprising:

maintaining the lock state when the second contact of the touch gesture is located in an area inside of the virtual preset touch line.

12. The method of claim 5, further comprising:

executing an application corresponding to the object when the second contact of the touch gesture is located in an area outside of the virtual preset touch line.

13. The method of claim 5, further comprising:

activating at least one virtual touch guide region on the screen in response to the first contact on the object;

maintaining mapping information between the at least one virtual touch guide region and at least one visual effect in a memory; and

displaying a visual effect corresponding to a virtual touch guide region in which a third contact of the touch gesture is included based on the mapping information when the third contact belongs to one of the at least one virtual touch guide regions.

14. The method of claim 13, wherein the visual effect corresponding to the virtual touch guide region in which the third contact is included is one of cases where an object-set, including at least one touch-on object arranged one or on and around the contacted virtual touch guide region in which the third contact is included, appears and disappears.

15. The method of claim 13, wherein the visual effect corresponding to the virtual touch guide region in which the third contact is included is at least one of a transparency, a color, luminance, a brightness, a size, a shape, a rotating angle, and a location of an object-set.

16. The method of claim 5, further comprising:

displaying an object-set with at least one touch-on object;

activating at least one virtual touch guide line with a preset location in response to the first contact; and

when a third contact of the touch gesture is included in one of the at least one virtual touch guide regions, applying a visual effect corresponding to the virtual touch guide region in which the third contact is included with the object-set to display the applied visual effect on the screen.

17. An apparatus for providing a user interface, the apparatus comprising:

a controller controlling a display of a lock image in a lock state with respect to at least a partial user interface and an object for changing the lock state to a release state; and

a sensor sensing a first contact of a touch gesture on the object,

wherein the controller;

activates a virtual preset touch line having a looped curve shape surrounding the object in response to the first contact on the object; and

changes the lock state to the release state and removes the lock image from the display when a second contact of the touch gesture is located in an area outside of the virtual preset touch line.

18. The apparatus of claim 17, wherein the controller displays an object-set including at least one touch-on object and activates at least one virtual touch guide line with a preset location in response to the first contact;
