Comparison of the BCI Performance between the Semitransparent Face Pattern and the Traditional Face Pattern

Table 1

Configuration of the 12-flash pattern combination.

1,4	1,5	1,6	1,7	1,8	1,9
2,10	2,5	2,6	2,7	2,8	2,9
3,10	3,11	3,6	3,7	3,8	3,9
4,10	4,11	4,12	4,7	4,8	4,9
5,10	5,11	5,12	1,10	5,8	5,9
6,10	6,11	6,12	3,12	2,11	6,9

Notes. We named these 12-flash groups as “.” The numbers in the table represent the target character of the 12 flashes. The same number in the configuration would simultaneously present stimuli. For example, letter “A” was flashed in flash₁ and flash₄. The italicized numbers represent the positions that simultaneously presented face stimuli during flash₁₁.
