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

Table 3

Subjects’ responses to three questions for each pattern.

		S1	S2	S3	S4	S5	S6	S7	S8	S9	S10	AVG ± STD
Tired	F-P	2	2	2	1	2	2	1	2	1	1	1.6 ± 0.52
	STF-P	1	2	1	2	1	1	1	1	1	1	1.2 ± 0.42
Difficult	F-P	2	1	1	2	1	1	2	2	1	2	1.5 ± 0.53
	STF-P	1	2	1	1	1	2	1	2	1	1	1.3 ± 0.48
Annoyed	F-P	1	2	1	2	1	1	1	2	1	1	1.3 ± 0.48
	STF-P	1	1	1	2	1	1	1	2	1	1	1.2 ± 0.42

F-P = face pattern; STF-P = semitransparent face pattern. AVG is average and STD is standard deviation.
