Type: dissertation
Abstract: A bio-cybemetic, closed-loop system was validated for use in an adaptively automated environment. Subjects were asked to perform either one task or three tasks from the MAT battery. EEG was continuously sampled while they performed the task and an EEG index was derived (20 beta/alpha + theta). The system made allocation decisions based upon the level of operator engagement as determined by the EEG index. The NASA-TLX was administered after each trial. The results of the study demonstrated that it was possible to moderate an operator's level of engagement through a closed-loop system driven by the operator's EEG. It also demonstrated that the system was sensitive to increases in mental workload. Theoretical and practical implications are discussed.
