1. A productivity and safety tracking system comprising:
a plurality of portable personal tracking apparatus attachable to a safety vest or garment, including a first portable personal tracking apparatus and a second portable personal tracking apparatus, wherein the first portable personal tracking apparatus is attachable to the safety vest or garment at a first torso location of the safety vest or garment, wherein the second portable personal tracking apparatus is attachable to the safety vest or garment at a second torso location of the safety vest or garment, and
wherein each of the first and second portable personal tracking apparatus comprises:
a respective inertial measurement sensor unit configured to measure a measurand selected from the group consisting of acceleration, angular velocity, and magnetic field;
a respective radio transceiver;
a controller unit operatively coupled to the respective radio transceiver and respective inertial measurement sensor unit;
wherein the first portable personal tracking apparatus is configured, by computer readable instructions, to generate a first inertial measurement data set associated with motion of the first torso location, wherein the second portable personal tracking apparatus is configured, by computer readable instructions, to generate a second inertial measurement data set associated with motion of the second torso location, and wherein the first and second inertial measurement data sets are concatenated for each of a plurality of nodes to form a respective feature set, wherein feature sets for each of the plurality of nodes are concatenated to form an input vector for classifier training or classification; and
wherein the input vector is subsequently used, in a motion recognition classification operation, to identify a sequenced motion from a set of candidate sequenced motions of a person.
