Abstract: A method for controlling a motion tracking system, including the steps of: digitally processing sound waves detected by a plurality of microphones so as to detect a voice of a user and estimate a first direction of the user; digitally processing electromagnetic waves captured by antennas so as to detect data packets transmitted to a computing apparatus by sensors and estimate second directions of each sensor; digitally averaging the second directions so as to provide an average direction for the sensors; digitally computing a difference between the first direction and the average direction; and starting to digitally track motion of the user based on measurements of each sensor when the computed difference does not exceed a predetermined difference threshold.

Abstract: Methods for automatically monitoring operation of a motion tracking system and actuating based on the operation, the motion tracking system comprising both a computing device, and a plurality of inertial measurement units adapted to be arranged on a body of a user. The computing device processes measurements of the units and sound captured by at least one microphone to provide flags related to the motion tracking procedure with regards to the motion input and the sound input, and actuates when motion-related flags and sound-related flags have been provided.

Abstract: A method for establishing wireless communications connections between sensors and a computing apparatus of a motion tracking system include the steps: processing radiofrequency signals received by the computing apparatus and transmitted by each sensor, each radiofrequency signal including an advertisement package of the respective sensor; providing a number of RSSI per sensor based on the processed radiofrequency signals; computing and storing mean RSSI values based on the number of RSSI so that a number of RSSImean values is computed per sensor; computing velocities of change of RSSImean, vRSSI, based on the number of RSSImean values so that a number of vRSSI values is computed per sensor; establishing the wireless communications for which at least the following is fulfilled: the computing apparatus determines that at least some vRSSI values within a first period of the number of vRSSI values of each sensor has a modulus greater than a predetermined minimum velocity.

Abstract: A method for allowing or disallowing control of a motion tracking system by means of voice, comprising: digitally processing sound detected by each microphone of the at least one microphone; digitally computing SNR by computing both first energy of a voice signal in the detected sound and second energy of noise in the detected sound; digitally processing electromagnetic waves captured by each antenna of the at least one antenna so as to detect data packets transmitted to the computing apparatus by each sensor of the plurality of sensors, each data packet including RSSI of a respective sensor; digitally computing distance between each sensor and the computing apparatus based on the RSSI of the data packets received from the respective sensor; digitally computing a percentage of sensors of the plurality of sensors having at least one of: a distance exceeding a predetermined maximum distance threshold, and a change in distance exceeding a predetermined maximum changing distance threshold; and digitally setting a

Abstract: Motion tracking systems and methods for determining how trackers are positioned on body members of a person, the methods including: wirelessly receiving, by a computing device, one or more first data packets of each tracker; digitally determining a first direction in which the computing device is relative to the respective tracker by computing an angle of departure of the one or more first data packets; digitally determining based on the first directions, a second direction in which each tracker is relative to one or more other trackers; and digitally determining on which body member is each tracker positioned on the person at least based on both the second directions and the body members requiring to have a tracker positioned thereon. Also, systems and methods in which angles of arrival are computed for determining the first directions.
