Apparatus and method for monitoring performance of a physical activity

A system comprising:

• a set of monitoring devices, each device being attached to a limb of the subject associated with a distinct subject performing physical tasks in connection with a set of workplace activities, and having:
• a set of assemblies, constituting a subsystem, each assembly including a housing and a set of sensors and configured for removable attachment to a body part of the subject;
• a controller, disposed in the subsystem, coupled to the sensors, and configured to perform initial processing of data from the sensors;
• and
• a wireless transceiver disposed in the subsystem, coupled to the controller, and configured to transmit the initially processed data to a server system;
• and
• a non-transitory computer readable storage medium storing a set of instructions, which, when executed by the server system, establish a set of computer processes, the computer processes comprising:
• receiving by the server system, over the network, from each member of the set of monitoring devices, data characterizing performance of the corresponding subject;
• processing and storing the received data to provide, in a database, performance data, organized according to subject, characterizing physical performance of the corresponding subject in carrying out the set of workplace activities;
• further processing the performance data to develop for each subject an ergonomic score for a set of ergonomic metrics based on a predefined ergonomic assessment method, to quantify motions that are unproductive and suboptimal;
• and
• causing distribution of the-ergonomic score for each subject to a set of recipients.
