Claim 10:
11. A non-transitory computer readable medium storing a program causing a computer to execute:
a step of acquiring sensing information of a sensor attached to a target part of a body of a subject, the sensing information including quaternion information;
a step of detecting an attaching direction of the sensor in a stationary state with respect to a reference direction defined based on the target part, wherein the reference direction remains the same relative to the target part when a position of the sensor with respect to the target part changes, the reference direction defined as an axial direction of a band attached to the target part;
a step of executing tagging processing for associating the attaching direction of the sensor with sensing-related information, the sensing-related information including the sensing information and information obtained by converting the quaternion information into rotation angle information;
a step of calculating a motion state of the target part based on the sensing-related information tagged with the attaching direction;
a step of outputting the calculated motion state of the target part with an indication of relation to the attaching directions;
a step of determining that an attaching direction changing event has occurred based on a difference of attaching directions measured before and after a predetermined timing, and
a step of updating the attaching direction of the sensor based on determining that the attaching direction changing event has occurred.
