Method of sensing rotation of rotation member and electronic device performing same

A wearable electronic device comprising:

• a housing including one side having a substantially circular opening;
• at least one detent disposed at the housing;
• a rotation member of the wearable electronic device, wherein the rotation member comprises a substantially circular structure configured to be rotatably positioned in or around the opening of the housing and including at least one groove being formed on a body of the structure to fit the at least one detent;
• a first sensor configured to detect a rotation of the structure to generate a first signal;
• a second sensor configured to detect that the at least one detent is inserted into the at least one groove;
• a processor coupled to the first sensor and the second sensor;
• and
• a memory coupled to the processor, wherein the memory includes instructions to enable the processor, on execution, to:
• receive the first signal from the first sensor,
• in response to receiving a second signal from the second sensor, determine, based on the second signal, whether the at least one detent is inserted into the at least one groove,
• in response to determining that the at least one detent is inserted into the at least one groove, correct the first signal to reflect an actual rotation of the structure, and
• perform a predetermined action, based on the corrected first signal.
