The mental tasks and corresponding class
labels of the binary left/right BCI and the 4-class whole system in paradigm A
and B. Note that the class label of left/right BCI corresponds to the movement
of the left/right side of the body. For example, in paradigm A, positive output
(+) of the left BCI indicates the left-hand movement. The subject is instructed
to execute or imagine the movements at both sides of his body simultaneously.
The left/right BCI only classifies the two kinds of movements of the left/right
side at the subject body.
