近年,Brain-Computer Interfaces (BCI)の研究が盛んであり,コミュニケーションのためのBCIであるP300 spellerが知られている.しかし,事前に学習データを計測する必要があり,被験者にとって負担になっている.本稿では,事前学習データの計測時間を短縮するため,未知データを用いた追加学習法を提案し,P300 spellerへの適用の効果をオフライン実験とオンライン実験により検証する.Recently, Brain-Computer Interfaces (BCIs) have been researched actively. The P300 speller, one of the communication tools of BCI, is well known. The process of recording training data places a lot of burden to the user before actual use. To reduce time for recording training data, this paper proposes an incremental training method, and evaluates the effectiveness of the proposed method by offline and online experiments.
