Abstract

An electronic device, according to an embodiment of the disclosure, may comprise: a touchscreen including a first portion and a second portion; a memory; and a processor operatively connected to the touchscreen and the memory. The memory may store instructions that, when executed, cause the processor to: recognize a first point at which a touch input is in contact with the second portion, recognize a second point at which the touch input is separated from the touch screen, recognize at least one third point at which the touch input is periodically in contact with the touch screen in a state in which the touch input is in contact with the touch screen, and activate the touch input based on whether at least one of the second point and the at least one third point is located outside a specified area having a specified radius set with respect to the first point.

First claim

What is claimed is:

1. An electronic device comprising:
a touch screen including a first portion and a second portion, wherein the first portion is relatively located at a center of the touch screen compared to the second portion and the second portion is relatively located at an edge of the touch screen compared to the first portion;
a memory; and
at least one processor operatively connected to the touch screen and the memory, and configured to:
recognize a first point where a touch input is detected on the second portion;
recognize a second point where the touch input is released on the first portion or the second portion of the touch screen;
activate an operation corresponding to the touch input based on the second point being located outside of a specified region having a specified radius set with respect to a location of the first point; and
deactivate the operation corresponding to the touch input based on the second point being located within the specified region.

2. The electronic device of claim 1 , wherein the first portion includes a planar region of the touch screen,
wherein the second portion includes a curved region of the touch screen.

3. The electronic device of claim 2 , wherein the at least one processor is configured so that the specified radius is to be determined based on a characteristic of the edge of the touch screen or a bezel of the electronic device,
wherein the characteristic of the edge of the touch screen includes a curvature of the second portion.

4. The electronic device of claim 1 , wherein the at least one processor is configured to:
deactivate the operation corresponding to touch input based on a difference between a first time point at which the first point is recognized and a second time point at which the second point is recognized exceeding a set specified duration; and
activate the operation corresponding to touch input based on the difference between the first time point and the second time point being equal to or less than the set specified duration.

5. The electronic device of claim 1 , wherein the at least one processor is configured to:
recognize one or more third points where the touch input is detected on the touch screen while the touch input is in contact with the touch screen;
determine at least one third point being located out of the specified region from among the recognized one or more third points; and
activate the operation corresponding to the touch input based on the first point, the second point and the at least one third point.

6. The electronic device of claim 5 , to wherein the at least one processor is configured to:
generate one or more virtual touch points on a straight line connecting the at least one third point being located out of the specified region with the first point; and
activate the operation corresponding to the touch input based on the one or more virtual touch points.

7. The electronic device of claim 6 , wherein each of the first point, the second point, and the one or more third points has coordinate information corresponding to the touch screen,
wherein the at least one processor is configured to:
generate one or more coordinate information respectively corresponding to the second point, the at least one third point being located out of the specified region, and the one or more virtual touch points; and
activate the operation corresponding to the touch input based on at least some of the one or more coordinate information.

8. The electronic device of claim 7 , wherein the at least one processor is configured to:
at least temporarily store the coordinate information of each of the first point, the second point, and the one or more third points in the memory; and
delete coordinate information of a point located within the specified region among the one or more third points from the memory.

9. The electronic device of claim 1 , wherein the at least one processor is configured to:
activate the operation corresponding to touch input based on the second point being located within the specified region and a difference between a first time point at which the first point is recognized and a second time point at which the second point is recognized being equal to or less than a set specified duration.

10. The electronic device of claim 1 , wherein the at least one processor is configured to:
recognize an area of the touch input in contact with the touch screen;
deactivate the operation corresponding to touch input based on the area exceeding a set specified area; and
activate the operation corresponding to touch input based on the area being equal to or less than the set specified area.

11. A method of operating an electronic device including a touch screen including a first portion located at a center of the touch screen and a second portion located at an edge of the touch screen, the method comprising:
recognizing a first point where a touch input is detected on the second portion of the touch screen;
recognizing a second point where the touch input is released on the first portion or the second portion of the touch screen;
activating an operation corresponding to the touch input based on the second point being located outside of a specified region having a specified radius set with respect to a location of the first point; and
deactivating the operation corresponding to the touch input based on the second point being located within the specified region.

12. The method of claim 11 , further comprising:
storing first location information indicating a location of the first point and second location information indicating a location of the second point in a memory included in the electronic device.

13. The method of claim 12 , wherein the activating of the operation includes:
recognizing one or more third points where the touch input is detected on the touch screen while the touch input is in contact with the touch screen;
determining at least one third point being located out of the specified region from among the recognized one or more third points; and
activating the operation corresponding to the touch input based on the first point, the second point and the at least one third point.

14. The method of claim 12 , wherein the deactivating of the operation includes:
deleting at least one of the first location information, and the second location information at least partially stored in the memory.

15. The method of claim 13 , further comprising:
storing first time point information indicating a time point at which the first point is recognized, second time point information indicating a time point at which the second point is recognized, and third time point information indicating a time point at which the at least one third point is recognized in the memory included in the electronic device.

16. The method of claim 15 , wherein the activating of the operation at least partially includes:
determining whether a difference between the first time point information and the second time point information exceeds a specified duration.

17. The method of claim 16 , wherein the activating of the operation includes:
activating the operation corresponding to the touch input in response to the at least one of the second point and the one or more third points being located out of the specified region; and
deactivating the operation corresponding to the touch input in response to at least one of the second point and the one or more third points being located within the specified region and the difference between the first time point information and the second t
