A system and method of hierarchical monitoring for subordinate assessment
is described. Generally, the system receives remotely sensed data about a
user's physiology and contextual state, and extracts features that are
related to the workload currently being experienced by a single
subordinate and/or group of subordinates. The system builds workload
indices based on levels of these features. The system uses statistical
process control techniques in conjunction with the workload indices to
identify suboptimal user states. Information regarding a particular
subordinate or the group of subordinates may be presented in a variety of
different ways. As a result, a superior can easily determine the
condition of the one or more subordinates and make task adjustments to
influence workload levels.
