要約(日本語): This paper describes the online voluntary eye blink detection method using electrooculogram (EOG). There are still many challenges to apply a brain-computer interface (BCI) to real-life applications. In general BCI systems, there is a possibility of incorrect and unintentional input because they are automatically selected even if requirements are accidentally met. This study aims to propose the voluntary eye blink detection method and apply it to trigger switch of BCI systems. In our method, normal blink, double blink, wink can be detected from EOG. We employed the amplitude of vertical and horizontal EOG in feature extraction, and support vector machine in classification. As the result, an accuracy of 97.28% was obtained in offline analysis. In addition, we applied it to online system.
