Abstract(in English) | In this paper, we will show you the results of feature extraction for brain computer interface (BCI) using steady-state visual evoked potential. Our final goal is to develop small and cheap SSVEP-BCI system. To achive our final goal, it is important to focus on EEG signals including environmental noises and analysis mothod. Therefore, we recored EEG signals without shild room and analyze EEG signals by only the discrete Fourier transformation (DFT). In this experiment, we show the subjects lighting flicker stimulis by a red LED. The flicking frequency is 10, 15, 20, and 25Hz. Results show that the detection ratio is 84% by using a spectrum intensity ratio with unsuper-vised classification while the simple feature using spectrum amplitude performs 72%. It is confirmed that the SSVEP is more enhanced by using spectrum intensity ratio. In order to avoid the false-positive detection due to harmonics, we need to apply a suitable classification technique. |
