摘要
通过分析脑电信号与人体精神状态的关系以及脑电检测方法,设计相应电路对脑电信号采集并进行分析,重点对从脑电信号中解析出的人体精神专注度的数据进行研究和应用,设计出可以采集脑电信号,测试者通过调节注意力,用注意力的集中程度来改变彩灯颜色变化的脑电检测设备,进行脑-机交互操作。
By analyzing the relations between electroencephalograph（EEG） signal and human mental state and the method of EEG detection,an EEG detecting equipment was designed to detect and analyze the data obtained fi：om the EEG signal. The data related to the mental concentration was primarily studied. By using the equipment to detect human＇s EEG signal,people can simply control and change the color of the lamp by adjusting his/her attention level so that to do brain-computer interaction.
