Adjustment of frequency of a motion measuring system

A motion measuring system comprising a plurality of sensors and at least one computing device in communication with the plurality of sensors, the plurality of sensors comprising one or more optical sensors and one or more body member sensors, and the motion measuring system being configured to perform operations comprising:

• using a user interface provided by the at least one computing device to instruct a subject to perform a movement of one or more body members of the subject;
• performing an adjustment of one or more frequencies of one or more of the plurality of sensors to reduce a power consumption of at least one of the plurality of sensors to thereby reduce a power consumption of the motion measuring system, wherein the adjustment is performed based at least in part on the movement which the subject is instructed to perform;
• and
• during or subsequent to performing the adjustment of the one or more frequencies, measuring motion of the subject using the one or more optical sensors, wherein, during the measuring of the motion of the subject, the one or more optical sensors is arranged at a distance from the subject so that the one or more optical sensors receive light from the one or more body members of the subject, and the one or more body member sensors is arranged on at least one body member of the subject.

A non-transitory computer readable medium comprising instructions that, when executed by at least one computer processor, cause the at least one computer processor to perform operations comprising:

• in a motion measuring system comprising a plurality of sensors and at least one computing device in communication with the plurality of sensors, the plurality of sensors comprising one or more optical sensors and one or more body member sensors, the one or more optical sensors arranged at a distance from a subject so that the one or more optical sensors receive light from one or more body members of the subject, and the one or more body member sensors arranged on at least one body member of the subject, using a user interface provided by the at least one computing device to instruct the subject to perform a movement of the one or more body members;
• performing an adjustment of one or more frequencies of one or more of the plurality of sensors to reduce a power consumption of at least one of the plurality of sensors to thereby reduce a power consumption of the motion measuring system, wherein the adjustment is performed based at least in part on the movement which the subject is instructed to perform;
• and
• during or subsequent to performing the adjustment of the one or more frequencies, measuring motion of the subject using the one or more optical sensors of the motion measuring system.
