detect an interference factor interfering with the sliding operation of the edge area,

based on a detection of the interference factor, provide a first feedback indicating that the interference factor exists, and

expose the second part to the outside by sliding at least part of the flexible display including the edge area based on detecting that the interference factor is removed.

2. The electronic device of claim 1 , wherein the memory stores instructions configured to, when executed by the processor, cause the electronic device to:

control the flexible display to display a guide object for receiving a second user input related to a sliding direction of the edge area, together with the indicator, and

based on receiving the second user input through the guide object, expose the second part to the outside by sliding the at least part of the flexible display including the edge area according to the sliding direction.

3. The electronic device of claim 2 , wherein the guide object includes a first object related to a first sliding length of the flexible display, and a second object related to a second sliding length of the flexible display, the second sliding length being greater than the first sliding length, and

wherein the memory stores instructions configured to, when executed by the processor, cause the electronic device to slide the at least part of the flexible display based on a sliding length related to an object selected by the second user input from among the first object and the second object.

4. The electronic device of claim 1 , wherein the first feedback includes at least one of vibration, sound, lighting, or message display.

5. The electronic device of claim 1 , wherein the memory stores instructions configured to, when executed by the processor, cause the electronic device to, based on the removal of the interference factor not being detected for a predetermined time after the first feedback is provided, provide a second feedback with a greater intensity than the first feedback.

6. The electronic device of claim 1 , wherein the first feedback is set by a user input.

7. The electronic device of claim 1 , wherein the memory stores instructions configured to, when executed by the processor, cause the electronic device to, based on detection of at least one of a touch input or a pressure greater than or equal to a predetermined value in at least part of the edge area, determine that the interference factor is detected.

8. The electronic device of claim 1 , wherein the memory stores instructions configured to, when executed by the processor, cause the electronic device to, based on receiving the first user input, identify the edge area with respect to a basic display direction of a UI screen of the electronic device.

9. The electronic device of claim 8 , wherein the memory stores instructions configured to, when executed by the processor, cause the electronic device to:

control the flexible display to display an area of first content, corresponding to the first part through the first part in the state in which the first part of the flexible display is exposed to the outside,

based on receiving the first user input, compare the basic display direction of the UI screen with a direction of the first content, and

control the flexible display to display an area of second content, corresponding to the second part based on a result of the comparison in a state in which the second part is exposed by sliding of the at least part of the flexible display.

10. A method of controlling an electronic device, the method comprising:

based on receiving a first user input on a flexible display of the electronic device, in a state in which a first part of the flexible display is exposed to the outside, for a sliding operation to further expose a second part of the flexible display to the outside;

displaying an indicator in at least part of an area of the first part of the flexible display corresponding to an edge area of the flexible display, wherein the edge area is an end area of the flexible display which moves in an outward direction from the housing based on the sliding operation;

detecting an interference factor interfering with the sliding operation of the edge area;

based on detection of the interference factor, providing a first feedback indicating that the interference factor exists; and

exposing the second part to the outside by sliding at least part of the flexible display including the edge area based on detecting that the interference factor is removed.

11. The method of claim 10 , further comprising displaying a guide object for receiving a second user input related to a sliding direction of the edge area, together with the indicator,

wherein the exposing the second part to the outside comprises, based on receiving the second user input through the guide object, exposes the second part to the outside by sliding the at least part of the flexible display including the edge area according to the sliding direction.

12. The method of claim 11 , wherein the guide object includes a first object related to a first sliding length of the flexible display, and a second object related to a second sliding length of the flexible display, the second sliding length being greater than the first sliding length, and

wherein the exposing the second part to the outside comprises sliding the at least part of the flexible display based on a sliding length related to an object selected by the second user input from among the first object and the second object.

13. The method of claim 10 , wherein the first feedback includes at least one of vibration, sound, lighting, or message display.

14. The method of claim 10 , further comprising, based on the removal of the interference factor not being detected during a predetermined time after the first feedback is provided, providing a second feedback with a greater intensity than the first feedback.

15. The method of claim 10 , wherein the first feedback may be set by a user input.

16. The method of claim 10 , wherein the detecting the interference factor comprises, based on detection of at least one of a touch input or a pressure greater than or equal to a predetermined value in at least part of the edge area, determining that the interference factor is detected.

17. The method of claim 10 , further comprising identifying, based on receiving the first user input, the edge area of the flexible display to be slid with respect to a basic display direction of a UI screen of the electronic device.

18. The method of claim 17 , further comprising:

displaying an area of first content, corresponding to the first part through the first part in the state in which the first part of the flexible display is exposed to the outside;

based on receiving the first user input, comparing the basic display direction of the UI screen with a direction of the first content; and

displaying an area of second content, corresponding to the second part based on a result of the comparison in a state in which the second part is exposed by sliding of the at least part of the flexible display.
