Recently, Brain-Computer Interface (BCI) has been studied by many researchers. In this study, brain activity of the frontal lobe was measured using Near-Infrared Spectroscopy (NIRS) when the subject feels comfortable or uncomfortable. Specifically, two kinds of emotion were classified by combination of five features and three discriminant analyses when the subject looked at the pictures in the screen. Presented pictures were three types: Figure, Color and Image task. As a result, maximum discrimination rate was 85% when training data were identical to the test data. Average discrimination rate was 10% lower when training data were different from test data. Discrimination rates varied by combination of features and discriminant analyses.
