Figure Lengend Snippet: ( a ) For CLA and HaLT interaction paradigms, the eGUI displayed six icons symbolizing left hand, right hand, left leg, right leg, and tongue motor imageries together with a passive imagery indicated by a circle. A fixation point was shown in the center of the screen. Action signals selecting the imagery to be implemented were shown as a red rectangle around the respective motor imagery icon. ( b ) For the 5 F interaction paradigm, the eGUI displayed a hand icon with five fingers. The action signal was shown as a number from 1 to 5 directly above the finger for which motor imagery was to be implemented. ( c ) For the FreeForm interaction paradigm, the eGUI showed a fixation point in the center of the screen, total left and right key-press counts, and the letter of the last key press. The participants pressed keys using their right and left hands voluntarily, in a self-paced manner, while the eGUI kept track of the pressed keys and the key press number.
