Brain Actuated Control of a Roll Axis Tracking Simulator

Abstract

Investigations of steady-state evoked EEG potentials as indicators of mental workload have led to 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 an a kinesthetically salient control/feedback environment. This paper discusses efforts to make use of a methodology for using the derivative of selected brain resonances as a control signal in the kinesthetically salient environment of the RATS.
