| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | P300 speller is one of the Brain Computer Interfaces, which uses P300 as the feature quantity and allows users to select letters just by thinking. Because of the low signal-to-noise ratio of the P300, signal averaging is often performed to improve the spelling accuracy instead of the degradation of the spelling speed．In texts, there is variability in occurrence probabilities and transition probabilities between letters．This paper proposes Japanese interface of P300 speller considering the occurrence probabilities and the transition probabilities as the priori probabilities. It shows that the spelling speed is improved by the proposed method comparing with the conventional method. | |
