Abstract

An electronic device and a method for changing an object according to a bending state. The method includes analyzing coordinates of touch areas to set an arbitrary area; checking that at least one object is included in the set area; and controlling a layout of the at least one object included in the set area according to a bending state.

Claims

1. A method for operating an electronic device, comprising:

displaying a list comprising a plurality of shortened text messages on a flexible screen in respective cells, wherein each size of corresponding unshortened text messages exceeds a size of a respective cell of the list;

receiving a selection of at least one shortened text message among the plurality of shortened text messages on the flexible screen in a significantly flat state; and

in response to detecting a convex bending of the flexible screen, displaying an unshortened text message of the at least one shortened text message selected in the significantly flat state.

2. The method of claim 1, further comprising:

checking central coordinates of a first touch area and a second touch area;

generating four coordinates using the central coordinates of the first touch area and the central coordinates of the second touch area; and

setting the arbitrary area by connecting the generated four coordinates.

3. The method of claim 2, wherein generating four coordinates using the central coordinates of the first touch area and the central coordinates of the second touch area includes:

generating first coordinates composed of an x-coordinate of the central coordinates of the first touch area and a y-coordinate of the central coordinates of the second touch area;

generating second coordinates composed of the central coordinates of the second touch area;

generating third coordinates composed of the central coordinates of the first touch area; and

generating fourth coordinates composed of an x-coordinate of the central coordinates of the second touch area and a y coordinate of the central coordinates of the first touch area.

4. The method of claim 1, wherein the full text message is returned to be the shortened text message in the list in response to detecting a concave bending of the flexible screen.

5. The method of claim 1, further comprising:

selecting the at least one object included in the set area.

6. The method of claim 1, wherein the flexible screen is convexly bent frontward in a portion between the first touch area and the second touch area.

7. The method of claim 1, wherein the flexible screen is concavely bent backward in a portion between the first touch area and the second touch area.

8. The method of claim 1, further comprising:

checking that the electronic device is in a positive bending state in which a set portion between a first touch area and a second touch area is convexly bent frontward; and

converting at least one list included in the set area into a text form and displaying a relevant text.

9. The method of claim 8, further comprising:

checking that the electronic device is in a negative bending state in which the set portion between the first touch area and the second touch area is concavely bent backward; and

converting at least one displayed text into a list form and displaying a relevant list.

10. The method of claim 1, wherein controlling a layout of the at least one object included in the set area according to a bending state includes:

checking that the electronic device is in a positive bending state in which a set portion between a first touch area and a second touch area is convexly bent frontward; and

enlarging at least one image or pop-up window included in the set area to a predetermined size and displaying the enlarged image or pop-up window.

11. The method of claim 10, further comprising:

checking that the electronic device is in a flat state in which the set portion, which had been convexly bent frontward, is flattened.

12. The method of claim 10, further comprising:

checking that the electronic device is in the negative bending state in which the set portion between the first touch area and the second touch area is concavely bent backward; and

reducing the image or pop-up window which is enlarged to the predetermined size and displayed to a size prior to enlargement and displaying the reduced image or pop-up window.

13. The method of claim 12, further comprising:

checking that the electronic device is in a flat state in which the set portion, which had been concavely bent backward, is flattened.

14. An electronic device, comprising:

a flexible screen configured to display an image; and

a processor unit configured to;

display a list comprising a plurality of shortened text messages on the flexible screen in respective cells, wherein each size of corresponding unshortened text messages exceeds a size of a respective cell of the list;

receive a selection of at least one shortened text message among the plurality of shortened text messages on the flexible screen in a significantly flat state; and

in response to detecting a convex bending of the flexible screen, display an unshortened text message of the at least one shortened text message selected in the significantly flat state.

15. The electronic device of claim 14, wherein the processor unit is configured to:

check central coordinates of a first touch area and a second touch area, generates four coordinates using the central coordinates of the first touch area and the central coordinates of the second touch area, and
