| Outline of Final Research Achievements |
Brain-computer interface (BCI) is a technology that translates the user's brain activity into computer instructions and it is applied to communication and device operation. In this study, we developed a P300-type BCI to support the expression of intention based on hierarchical menu presentation by voice. Using EEG signal processing methods based on empirical mode decomposition or transfer learning, the highest accuracy was 88%. We have developed to display pre-prepared sentences based on the results of menu choices.
