A Novel Design of 4-Class BCI Using Two Binary Classifiers and Parallel Mental Tasks
Figure 1
(a) The map between the two classes of the
left/right BCI and the 4 classes of the whole system in paradigm A (also see
Table I(a)). The 4-class classification result of the total system is determined
by the outputs of the left BCI and right BCI. For example, when and only when
both left BCI and right BCI have positive outputs, the class of the total
system will be regarded as 4. (b) The map in paradigm B is similar to that of
paradigm A except that it involves foot movement.
