我们开发了一个低成本的，事件相关去极化（ERD）测量系统，使用消费级脑电图系统（Epotiv Epoc）的运动想象（MI）相关的脑机接口（BMI）的应用程序。我们通过比较Epoc和医用级EEG系统（g.USBamp：g.tec medical engineering）同时记录的EEG计算的ERD功率，研究了Epoc ERD功率检测的准确性。11名健康受试者在手部运动视频的观察下进行了手握滚动的网球并打开抓握的手的MI。Epoc和g之间的平均ERD功效相当。测试了两种手势的USBamp。Epoc的ERD检测准确率为70.5%。考虑到Epoc的价格，我们的研究结果表明，Epoc可能是一个很好的替代医疗级EEG系统的目的，MI为基础的BMI。关键词：BMI，BMI，事件相关性去硬化
We developed a low-cost, event-related desynchronization (ERD) measurement system using consumer-grade EEG system (Emotiv Epoc) for application of motor-imagery (MI) related brain machine interface (BMI). We investigated accuracy of ERD power detection of Epoc by comparing the ERD power calculated from simultaneously recorded EEG via Epoc and medical-grade EEG system (g.USBamp: g.tec medical engineering). Eleven healthy participants performed MI of holding a rolling tennis ball and opening the grasped hand under the observation of hand movement video. The mean ERD power was comparable between Epoc and g. USBamp with both hand gestures tested. ERD detection accuracy of Epoc was 70.5% of the all trials tested. Considering the price of Epoc, our results suggest that Epoc could be a good substitute for medical-grade EEG systems for the purpose of MI-based BMI.
