簡易ブレインマシーンインターフェースを利用した機械基礎実習用安全装置の開発

抄録

Authors belong to school, had ever experienced one serious incident of a students in machine-tool practice. This study dealt with the development of emergency-stop system of machine tool for educational practice in college by means of monitoring neural oscillation. In order to monitor neural oscillation, the study employed commercial-based low-cost Brain Machine Interface (BMI). This interface can measure brain waves, such as alpha，beta, and theta waves. New interface to control machine tool with PC, also had been developed and basic emergency-stop experiment, that programed PC detect the non-concentration condition of student through BMI, was executed. The system distinguishes whether the subject concentrate on machine-tool practice with his brain wave，the system demonstrates emergency stop of machine-tool spindle when his concentration is below preset threshold. The experimental result shows us the feasibility of the developed system.
