On-line operator skill assessment for telerobot operation using electroencephalo-graph (eeg)

States of human teleoperator have great impacts on teleoperation. However, most research investigated the stability or telepresence of the telerobotics, but few of them focused on the effect of the teleoperator. This paper presents an on-line skill assessment method in the teleoperation, based on a new concept named by skill of teleoperator (SoT), which represents the skill level of the human teleoperator from the view angle of the brain states. The basic idea is that the teleoperators with different skill levels have different brain states during the teleoperation. The skill level of the teleoperator can be easily assessed on line by wearing an Emotiv headset during the teleoperation. Experiments were performed to train a B-spline neural network for establishing relationship between SoT and the brain states of the teleoperator. © 2012 IEEE.Link_to_subscribed_fulltex
