| Outline of Final Research Achievements |
As a result, the time required for the communication was about 12 seconds, and the average accuracy rate of 4 subjects was 87%. Since the device uses the change of the electroencephalogram which appears at the time of imagination of the motion of hands and arms, it does not require visual information and can be used in the closed eyes state. Because there are few communication devices available in the closed eyes state, it can be expected to increase the choice of communication devices for people with amyotrophic lateral sclerosis.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では、これまで視覚情報を併用するブレイン・コンピュータ・インタフェースの分野で使用されていた「手や腕の動作の想像時に現れる脳波の変化」を閉眼状態における意思伝達に応用した。閉眼状態で使用可能な意思伝達装置は少ないため、筋萎縮性側索硬化症等の方々のための意思伝達手段の選択肢を増やすことが期待できる。
