Assignee: SWORD HEALTH, S.A.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 11:
12. A motion tracking system comprising:
a plurality of sensors adapted for arrangement on a body of a user and configured to wirelessly transmit data packets, each of the data packets including one or more measurements of a respective sensor of the plurality of sensors; and
a computing apparatus comprising:
a plurality of antennas;
a plurality of microphones;
at least one memory; and
at least one processor configured to:
process sound waves detected by each microphone of the plurality of microphones so as to detect a voice of the user and estimate a first direction of the user relative to the computing apparatus based on the detected sound waves;
process electromagnetic waves captured by each antenna of the plurality of antennas so as to detect data packets transmitted to the computing apparatus by each sensor of the plurality of sensors and estimate second directions of each sensor of the plurality of sensors relative to the computing apparatus based on the captured electromagnetic waves, each of the data packets including one or more measurements of a respective sensor of the plurality of sensors;
average the second directions to provide an average direction for the plurality of sensors;
compute a difference between the first direction and the average direction; and
start to track motion of the user based on measurements of each sensor of the plurality of sensors in the data packets when the computed difference does not exceed a predetermined difference threshold.
