a Compensated trajectory (red) reaches more closely to the target object than the raw hand trajectory predicted from EEG. Blue line indicates trajectory with no compensation. b Definition of the joint angles of the robotic arm. c Green line indicates the ideal joint angle to reach the target object. Joint angles are closer to the ideal joint angles with compensation (red) than without (blue)
