wherein the processor is further configured to:

display the first interface when a rotation of the portable device at a first threshold angle or more based on the front direction is detected in the folded state.

6. The portable device of claim 1 , wherein the first object corresponds to an object located in the first part and the second object corresponds to an object located in the second part.

7. The portable device of claim 6 , wherein the processor is further configured to:

display the first application corresponding to the first object on the front display area of the first body and display a second application corresponding to the second object on the front display area of the second body when the first triggering signal is detected after a second control input selecting the second object is further detected.

8. The portable device of claim 7 , wherein the processor is further configured to:

display the first application on all of the front display area of the first body and the front display area of the second body when the first application is equal to the second application.

9. The portable device of claim 8 , wherein the processor is further configured to:

display a first content on the front display area of the first body and a second content on the second display area of the second body when the first object corresponds to the first content of the first application and the second object corresponds to the second content of the first application.

10. The portable device of claim 7 , wherein the processor is further configured to:

display the first application on the front display area of the first body and terminate the display of the second application when a second triggering signal changing from the unfolded state to the folded state is detected.

11. The portable device of claim 10 , wherein the processor is further configured to:

display the selected application based on a control input on the front display area of the first body and terminate the display of non-selected application when the second triggering signal is detected after the control input selecting any one of the first application and second application is detected when the portable device is in the unfolded state.

12. The portable device of claim 11 , wherein the folded state corresponds to a state that a back surface of the first body and a back surface of the second body overlap one another, and

wherein the processor is further configured to:

display the visual information only on the front display area of the first body when the portable device is in the folded state.

13. The portable device of claim 7 , wherein the processor is further configured to:

if the first triggering signal is detected while a second control input selecting the second object is not detect,

display the first application corresponding to the first object on the front display area of the first body and a second interface on the front display area of the second body.

14. The portable device of claim 13 , wherein the second interface corresponds to any one of a Home screen interface and a menu interface.

15. The portable device of claim 6 , wherein the processor is further configured to:

display a first indicator when the first control input is detected,

wherein the first indicator corresponds to an indicator that the first object is selected in the first part.

16. The portable device of claim 6 , wherein the processor is further configured to:

display the first application when the first triggering signal is detected within a first threshold time after the first control input is detected.

17. The portable device of claim 1 , wherein the first object corresponds to an object located in the first part, and

Wherein the processor is further configured to:

display multiple objects related to the first object on the second part when the first control input is detected.

18. The portable device of claim 1 , further comprising:

a third body, and

wherein the display unit further displays visual information on at least any one of a front display area of the third body and a side display area of the third body, and

wherein the folding sensor unit further detects whether or not the third body is being folded to the second body, and

wherein the processor is further configured to:

detect the folded state when all of the first body, the second body, and the third body are folded, and

display the first interface on the side display area, wherein the first interface further includes a third part,

display the first application on a front display area of the third body when the first object is located in the third part.

19. The portable device of claim 1 , wherein the portable device is a flexible device,

wherein the processor is further configured to set the first body and the second body based on a folding line along which the flexible device is folded.

20. As a method for controlling a portable device comprising a first body and a second body, the method comprises:

detecting a folded state that the first body is folded to the second body;

displaying a first interface including multiple objects on a side display area, wherein the first interface is composed of a first part and a second part;
