Abstract
Saccade-related electroencephalogram (EEG) signals have been the subject of application oriented research by our group toward developing a brain computer interface (BCI). Our goal is to develop novel BCI based on eye movements system employing EEG signals on-line. Most of the analysis of the saccade-related EEG data has been performed using ensemble averaging approaches. In signal processing method for BCI, raw EEG signals are analyzed. In ensemble averaging method which is major EEG analysis is not suitable for processing raw EEG signals. In order to process raw EEG data, we use independent component analysis. This paper presents extraction rate of saccade-related EEG signals by four ICA algorithms and six window size. As results of extracting rate focused on ICA algorithm, The JADE and Fast ICA have good results. As you know, calucuration time in Fast ICA is fater than calucuration time in JADE. Therefore, in this case, Fast ICA is best in order to extract saccade-related ICs. Next, we focus on extracting rate in each windows. The windows not including EEG signals after saccade has and the windows which has small window size is good extracting rate.
