A method of initializing attachment locations of a plurality of measurement sensors, the method being performed by a terminal, the method comprising: requesting selection manipulation of each measurement sensor of the plurality of measurement sensors, the measurement sensor being attached to a specific body unit; recognizing identification information of the measurement sensor, which agrees with the selection manipulation of the measurement sensor; matching the identification information with the specific body unit; and determining sensing data received from the measurement sensor, which corresponds to the identification information, as motion data of the specific body unit, when the plurality of measurement sensors are attached to the body of a user, requesting the user to perform a specific motion or posture by the terminal; as the motion or posture is performed, combining the sensing data with the corresponding specific body unit to generate whole body motion or whole posture information; and determining whether the whole body motion or whole body posture corresponds to a normal body motion, wherein when the user is requested to perform the specific posture, the determining whether the whole body posture corresponds to the normal body motion comprises: setting a sensing range of the specific body unit that agrees with the posture; and determining whether sensing data that has been received from the measurement sensor attached to the specific body unit is included within the sensing range; and characterized in that, when the whole body motion or whole body posture does not correspond to the normal motion, determining a pair of measurement sensors among the plurality of measurement sensors is attached to erroneous body units, which do not correspond to the normal body motion, calculating a pair of erroneous body units, the corresponding pair of the measurement sensors of which need to be replaced with each other is calculated by determining the sensing data corresponds to the normal motion; and requesting the user to exchange the locations of the measurement sensors attached to the erroneous body units. requesting selection manipulation of each measurement sensor of the plurality of measurement sensors, the measurement sensor being attached to a specific body unit; recognizing identification information of the measurement sensor, which agrees with the selection manipulation of the measurement sensor; matching the identification information with the specific body unit; and determining sensing data received from the measurement sensor, which corresponds to the identification information, as motion data of the specific body unit, when the plurality of measurement sensors are attached to the body of a user, requesting the user to perform a specific motion or posture by the terminal; as the motion or posture is performed, combining the sensing data with the corresponding specific body unit to generate whole body motion or whole posture information; and determining whether the whole body motion or whole body posture corresponds to a normal body motion, wherein when the user is requested to perform the specific posture, the determining whether the whole body posture corresponds to the normal body motion comprises: setting a sensing range of the specific body unit that agrees with the posture; and determining whether sensing data that has been received from the measurement sensor attached to the specific body unit is included within the sensing range; and characterized in that, when the whole body motion or whole body posture does not correspond to the normal motion, determining a pair of measurement sensors among the plurality of measurement sensors is attached to erroneous body units, which do not correspond to the normal body motion, calculating a pair of erroneous body units, the corresponding pair of the measurement sensors of which need to be replaced with each other is calculated by determining the sensing data corresponds to the normal motion; and requesting the user to exchange the locations of the measurement sensors attached to the erroneous body units. setting a sensing range of the specific body unit that agrees with the posture; and determining whether sensing data that has been received from the measurement sensor attached to the specific body unit is included within the sensing range; and characterized in that, when the whole body motion or whole body posture does not correspond to the normal motion, determining a pair of measurement sensors among the plurality of measurement sensors is attached to erroneous body units, which do not correspond to the normal body motion, calculating a pair of erroneous body units, the corresponding pair of the measurement sensors of which need to be replaced with each other is calculated by determining the sensing data corresponds to the normal motion; and requesting the user to exchange the locations of the measurement sensors attached to the erroneous body units.
