Abstract

An electronic device is provided. The electronic device includes a sensor module configured to detect an object positioned near the electronic device, a display, a memory storing instructions, and a processor electrically coupled with the sensor module, the display, and the memory. The processor, when executing the instructions, is configured to control the display to display first information guiding a portion of a user'"'"'s body positioned near the electronic device to maintain a first posture, to acquire a first sensing value by using the sensor module while the first posture is maintained, to control the display to display second information guiding an object to be positioned on one point of the portion of the user'"'"'s body, to acquire a second sensing value for the object by using the sensor module while the object is positioned on the one point, and to determine a first correction value by using the first sensing value and the second sensing value.

4. The electronic device as claimed in claim 3, wherein, based on the portion of the user'"'"'s body being a back of a hand, the first posture is a state in which the display and a back of a user'"'"'s hand are parallel with each other, and the second posture is a posture in which the display and the back of the user'"'"'s hand form an obtuse angle.

5. The electronic device as claimed in claim 3, wherein the processor, when executing the instructions, is further configured to, based on a sensing value included in the effective range being detected through the sensor module, control the display to display the first information.

6. The electronic device as claimed in claim 1, wherein based on the portion of the user'"'"'s body being a back of a hand, the processor, when executing the instructions, is further configured to:

control the display to display fourth information guiding a plurality of knuckles included in the back of the hand to be sequentially touched, and

acquire a fourth sensing value for the touch input by using the sensor module while the plurality of knuckles are touched.

7. The electronic device as claimed in claim 6, wherein the processor, when executing the instructions, is further configured to:

control the display to display fifth information guiding a finger of the user to be dragged at least once on the portion of the user'"'"'s body, and

acquire a fifth sensing value for the drag input by using the sensor module.

8. The electronic device as claimed in claim 7, wherein the processor, when executing the instructions, is further configured to determine a second correction value by using at least one of the fourth sensing value or the fifth sensing value.
