EVALUATION SYSTEM FOR USERS IN A WORKSITE
Disclosed herein is a worksite evaluation system for evaluating a plurality of users in a worksite comprising a plurality of data capture devices and an activity determination system configured to determine activity data of a user in dependence on the user's user data, wherein the activity determination system determines the activity data by using an activity classification algorithm, wherein the activity classification algorithm is trained to recognise a plurality of specific movement signatures of a user's head, with each specific movement signature corresponding to a different activity being performed. Each data capture device is disposed within a respective helmet for wearing by a respective user, wherein each data capture device is configured to obtain user data. Each data capture device comprises an inertial measurement unit configured to obtain motion data of a respective user's head as part of the user data; and a communication unit configured to transmit data dependent on the user data from the data capture device to a remote processing system.
