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.
