Abstract (in Japanese) (See Japanese page) 
(in English) The purpose of this study is searchingan appropriate classifier for motor-related cortical activity-based BMI for strolling in the 3-D virtual environment. To obtain this goal, we compared linear discriminant analysis (LDA) and quadratic discriminant analysis (QDA) for electroencephalogram (EEG) classification. Eight healthy volunteers participated the BMI training controlling their own avatar in a virtual reality. We acquired the EEG signals during repeating hand extension in both pre- and post-training conditions. To check the EEG pattern changes, we employed time-frequency analysis. In our results, the binary classification accuracies were 89.4% in LDA and 84.4% in QDA, respectively. This results suggests that LDA is a better method for the BMI system.
