Introduction to Real-Time State Assessment

摘要

Real-Time State Assessment (RTSA) is the act of continuously monitoring an individual in order to estimate the human's current state. Examples of real time state assessment include estimating workload, fatigue, stress, and attention from physiological measures such as Electroencephalogram (EEG) or eye-tracking inputs. When estimated in real-time, the state of the human can aid dynamic task allocation systems in determining when to intervene and what course of action should be taken to mitigate potential problems or to improve system performance. In this paper we provide an introduction to the field of RTSA study, including an overview of modeling techniques and assessment methods. RTSA's challenges are discussed, and recent work in the area is reviewed.
