P300 speller is one of the BCI that can input characters using P300 which is one of the characteristics in brain wave. Because of low S/N ratio in brain waves, it is necessary to average the signals to improve discriminant performance. However, averaging brain waves degrade the performance of input speed. In this paper, we propose a method which considers the appearance probability of `hiragana', transition probability between letters and prior probability after the input of `BS.' Moreover, we compare the proposed method with the conventional method and show that the performance is improved by the proposed method in P300 speller. |
