Abstract :
Investigations of steady-state evoked EEG potentials as indicators of mental workload have led to the successful implementation of a closed-loop paradigm allowing the possibility of brain-actuated control. A three-channel lock-in amplifier system (LAS-3) was used to obtain an artifact-free brain resonance signal at a specified frequency. Lead-lag compensation of the LAS-3 gain signal was investigated as a means to produce the brain-actuated control. A roll axis tracking simulator (RATS) was used as a kinesthetically salient control/feedback environment. A methodology is proposed for using the derivative of selected brain resonances as a control signal in the kinesthetically salient environment of the RATS
