Timing diagram of the experimental task and feature extraction. a) Experimental paradigm used for the EEG recordings. At the white cross the subjects rested with their eyes opened, at the left arrow, subjects performed left hand motor imagery, and right hand motor imagery at the right arrow. At the blue background, subjects could blink and rest their eyes. b) Shows the time interval selected as class 1(REST from 1.5 s to 2.5 s) and class 2 (RIGHTMI or LEFTMI from 3.4 s to 4.5 s) for the calibration CSP and feature extraction stages.
