AI summary

Disclosed are a system, a method, and a program for initializing an attachment location of a measurement sensor. The method of initializing an attachment location of at least one measurement sensor includes requesting selection of the measurement sensor that is attached to a specific body unit (S100); recognizing identification information of the measurement sensor, which agrees with a selection manipulation of the measurement sensor (S200); matching the identification information with the body unit (S300); and determining sensing data received from the measurement sensor, which corresponds to the identification information, as motion data of the body unit. According to the inventive concept, because attachment locations of a plurality of measurement sensors are initialized, a terminal may accurately calculate a posture or motion of the user.
