Abstract

An electronic device and method for recognizing a touch input on the electronic device is provided. The electronic device includes a touch panel and a processor. The processor configured to determine the type of an object contacting the touch panel, set, when the object is of a first type, a threshold for touch recognition on the touch panel to a first designated value, set, when the object is of a second type, the threshold to a second designated value, and recognize a touch input by the object on the basis of the threshold set to one of the first designated value and the second designated value.

First claim

What is claimed is:

1. An electronic device comprising:
a touch panel; and
a processor configured to:
detect a touch input by an object on the touch panel,
determine a type of the object contacting the touch panel,
set, when the object is of a first type, a threshold for recognizing a movement of the object in contact with the touch panel as a movement of the touch input to a first movement value,
set, when the object is of a second type, the threshold for recognizing a movement of the object in contact with the touch panel as a movement of the touch input to a second movement value, and
determine, in response to detecting a movement of the object in contact with the touch panel, whether to recognize the movement of the object as a movement of the touch input based on the set threshold according to the type of the object,
wherein the object of the first type is a stylus pen, and the object of the second type is a finger.

2. The electronic device of claim 1 , wherein the processor is further configured to determine the type of the object contacting the touch panel on the basis of a touch pressure applied by the object.

3. The electronic device of claim 1 , further comprising at least one pressure sensor to sense a touch pressure applied by an object, wherein the processor is further configured to determine that the object is of the first type when the touch pressure sensed by the pressure sensor is greater than or equal to a threshold pressure, and to determine that the object is of the second type when the touch pressure is lower than the threshold pressure.

4. The electronic device of claim 1 , wherein the touch panel includes a fingerprint recognition sensor, and wherein the processor is further configured to obtain a fingerprint related to the object using the fingerprint recognition sensor and to determine the type of the object at least partially on the basis of the obtained fingerprint.

5. The electronic device of claim 1 , wherein the processor is further configured to determine the type of the object contacting the touch panel on the basis of a touch area of the object contacting the touch panel.

6. The electronic device of claim 5 , wherein the processor is further configured to determine that the object is of the first type when the touch area is less than a threshold area, and to determine that the object is of the second type when the touch area is greater than or equal to the threshold area.

7. The electronic device of claim 1 , wherein, when the object is of the first type, the processor is further configured to set the threshold to one of multiple first movement values according to at least one of a touch area and a touch pressure.

8. The electronic device of claim 1 , wherein, when the object is of the second type, the processor is further configured to set the threshold to one of multiple second movement values according to at least one of a touch area and a touch pressure.

9. A method of touch input recognition for an electronic device, the method comprising:
detecting a touch input by an object on a touch panel;
determining a type of the object contacting the touch panel;
setting, when the object is of a first type, a threshold for recognizing a movement of the object in contact with the touch panel as a movement of the touch input on the touch panel to a first movement value;
setting, when the object is of a second type, the threshold for recognizing a movement of the object in contact with the touch panel as a movement of the touch input to a second movement value; and
determining, in response to detecting a movement of the object in contact with the touch panel, whether to recognize the movement of the object as a movement of the touch input based on the set threshold according to the type of the object,
wherein the object of the first type is a stylus pen, and the object of the second type is a finger.

10. The method of claim 9 , wherein determining the type of the object contacting the touch panel is based on a touch pressure applied by the object.

11. The method of claim 10 , wherein the electronic device comprises at least one pressure sensor to sense the touch pressure applied by the object, and wherein determining the type of an object comprises determining that the object is of the first type when the touch pressure sensed by the pressure sensor is greater than or equal to a threshold pressure, and determining that the object is of the second type when the touch pressure is lower than the threshold pressure.

12. The method of claim 9 , wherein the touch panel includes a fingerprint recognition sensor, and wherein determining the type of an object comprises obtaining a fingerprint related to the object using the fingerprint recognition sensor and determining the type of the object at least partially on the basis of the obtained fingerprint.

13. The method of claim 9 , wherein determining the type of the object contacting the touch panel is based on a touch area of the object.

14. The method of claim 13 , wherein determining the type of the object comprises:
determining that the object is of the first type when the touch area is less than a threshold area; and
determining that the object is of the second type when the touch area is greater than or equal to the threshold area.

15. The method of claim 9 , wherein setting a threshold to a first designated value comprises setting, when the object is of the first type, the threshold to one of multiple first movement values according to at least one of a touch area or a touch pressure.

16. The method of claim 9 , wherein setting the threshold to a second designated value comprises setting, when the object is of the second type, the threshold to one of multiple second movement values according to at least one of a touch area and a touch pressure.
