Abstract

A method of controlling a user terminal device including a touch screen divided into a main area and at least one sub area. The touch screen includes a first surface including the main area, a second surface extending from the first surface and including the at least one sub area, and wherein the second surface is curved or bent with respect to a plane of the first surface is provided. The method includes performing an unlocking operation to activate the user terminal device, in response to a first pinch gesture being input on the at least one sub area while the user terminal device is locked; and performing a locking operation to inactivate the user terminal device, in response to a second pinch gesture being input on the at least one sub area, while the user terminal device is unlocked.

First claim

What is claimed is:

1. A method of controlling a user terminal device including a touch screen divided into a main surface area, a first curved surface area extended from a first side of the main surface area and a second curved surface area extended from a second side of the main surface area, the method comprising:
receiving a first touch input on the first curved surface area and a second touch input on the second curved surface area, at least one of the first touch input and the second touch input being a drag gesture which at least one touch point contacted to a corresponding one of the first curved surface area and the second curved surface area moves along the corresponding one of the first curved surface area and the second curved surface area;
providing a portion of a home screen on the touch screen in response to the first touch input and the second touch input,
wherein the portion of the home screen corresponds to an area defined by a start of the drag gesture, an end of the drag gesture, and another of the at least one of the first touch input and the second touch input.

2. The method as claimed in claim 1 , further comprising displaying at least one object on the portion of the home screen, in response to the portion of the home screen being provided.

3. The method as claimed in claim 1 , further comprising executing different applications according to a size of the portion of the home screen, in response to the portion of the home screen being provided.

4. The method as claimed in claim 1 , further comprising displaying at least one object on a remaining area other than the portion of the home screen, in response to the portion of the home screen being provided.

5. A user terminal device comprising:
a touch screen divided into a main surface area, a first curved surface area extended from a first side of the main surface area and a second curved surface area extended from a second side of the main surface area; and
a controller configured to receive a first touch input on the first curved surface area and a second touch input on the second curved surface area, at least one of the first touch input and the second touch input being a drag gesture which at least one touch point contacted to a corresponding one of the first curved surface area and the second curved surface area moves along the corresponding one of the first curved surface area and the second curved surface area, and control providing a portion of a home screen on the touch screen in response to the first touch input and the second touch input,
wherein the portion of the home screen corresponds to an area defined by a start of the drag gesture, an end of the drag gesture, and another of the at least one of the first touch input and the second touch input.

6. The apparatus as claimed in claim 5 , wherein the controller is configured to, in response to the portion of the home screen being provided, display at least one object on the portion of the home screen.

7. The apparatus as claimed in claim 5 , wherein the controller is configured to, in response to the portion of the home screen being provided, execute different applications according to the size of the portion of the home screen.

8. The apparatus as claimed in claim 5 , wherein the controller is configured to, in response to the portion of the home screen being provided, display at least one object on a remaining area other than the portion of the home screen.

9. The apparatus as claimed in claim 5 , wherein the touch screen includes a boundary area where the main surface area and at least one of the first curved surface area and the second curved surface area meet and form an obtuse angle.

10. The apparatus as claimed in claim 5 , wherein the main surface area of the touch screen is disposed on a front surface of the user terminal device, and
wherein the at least one of the first curved surface area and the second curved surface area is disposed on at least one planar area from among a first side, a second side, and a back surface of the user terminal device.

11. A user terminal device comprising:
a bent touch screen comprising a main surface area, a first curved surface area extended from a first side of the main surface area and a second curved surface area extended from a second side of the main surface area, wherein at least one of the first curved surface area and the second curved surface area is bent or curved with respect to a plane of the main surface area;
a controller configured to receive a first touch input on the first curved surface area and a second touch input on the second curved surface area, at least one of the first touch input and the second touch input being a drag gesture which at least one touch point contacted to a corresponding one of the first curved surface area and the second curved surface area moves along the corresponding one of the first curved surface area and the second curved surface area, and control providing a portion of a home screen on the bent touch screen in response to the first touch input and the second touch input,
wherein the portion of the home screen corresponds to an area defined by a start of the drag gesture, an end of the drag gesture, and another of the at least one of the first touch input and the second touch input.

12. A method of operating a user terminal device, the method comprising:
providing a bent touch screen comprising a main surface area, a first curved surface area extended from a first side of the main surface area and a second curved surface area extended from a second side of the main surface area, wherein at least one of the first curved surface area and the second curved surface area is bent or curved with respect to a plane of the main surface area;
receiving a first touch input on the first curved surface area and a second touch input on the second curved surface area, at least one of the first touch input and the second touch input being a drag gesture which at least one touch point contacted to a corresponding one of the first curved surface area and the second curved surface area moves along the corresponding one of the first curved surface area and the second curved surface area; and
providing a portion of a home screen on the bent touch screen in response to the first touch input and the second touch input,
wherein the portion of the home screen corresponds to an area defined by a start of the drag gesture, an end of the drag gesture, and another of the at least one of the first touch input and the second touch input.
