DETECTION OF INCORRECT ARRANGEMENT OF INERTIAL MEASUREMENTS UNITS OF A MOTION TRACKING SYSTEM

摘要

A method for physical exercise of a person using a motion tracking system, the motion tracking system comprising a computing device and a plurality of inertial measurement units adapted to be arranged on body members of the person, the method comprising: digitally processing at least first sets of measurements provided by the units so as to determine whether and adjust the operation of the motion tracking system when: any unit of the plurality of units is arranged on a body member of the person with an orientation outside of a predetermined orientation range for a unit on that body member; and/or two or more units of the plurality of units may be arranged on interchanged body members of the person according to the predetermined unit arrangement; adjusting the operation of the motion tracking system when the computing device determines, based on at least the first sets of measurements, that: at least one unit has an orientation outside of the predetermined orientation range, and/or two or more units are arranged on interchanged body members; and digitally processing second sets of measurements provided by the units after the step of adjusting the operation of the motion tracking system so as to determine whether the person has performed the second predetermined movement according to a set of predetermined movement constraints.
