Electronic device for measuring posture of user and method thereof

A method for providing three-dimensional sound by an electronic device, the method comprising:

• generating first rotation angle information;
• establishing a connection to an external electronic device;
• receiving second rotation angle information and check data uniquely assigned to the second rotation angle information from the external electronic device;
• configuring a first time stamp based on a time of receiving the second rotation angle information and the check data;
• configuring a second time stamp based on a time of correcting the second rotation angle information and the check data;
• comparing the first time stamp and the second time stamp to calculate a delay time from the time of receiving the second rotation angle information to the time of correcting the second rotation angle information;
• correcting second rotation angle information based on the delay time;
• and
• generating posture information based on the first rotation angle information and the corrected second rotation angle information.

An electronic device comprising:

• a short-range communication module configured to perform short-distance communication with an external electronic device;
• a sensor for sensing a rotation angle of the electronic device;
• and
• a processor operatively connected to the short-range communication module and the sensor,
• wherein the processor is configured to:
• generate rotation angle information regarding the rotation angle of the electronic device, by using the sensor,
• generate check data uniquely assigned to the rotation angle information in response to generating the rotation angle information, and
• transmit the rotation angle information and the check data to the external electronic device by using the short-range communication module.
