摘要
目的:脑-机接口是指大脑和外部设备间直接进行通讯的系统。本文基于此技术为有运动功能障碍的残疾人设计了一个环境控制器。方法:提取受试者的稳态视觉诱发脑电信号进行处理,分辨出受试者所注视的目标,并将该控制目标对应的命令代码发送给执行机构,执行机构接收命令并将其转化为相应的控制动作。结果:经过一般的训练过程后,使用者能正确地利用稳态视觉诱发脑电控制常规电器的起停,能通过红外遥控设备控制电视和空调,能拨打电话并启动语音播放。结论:该系统提供了一种全新的基于脑-机接口技术的环境控制器,为残疾人的日常生活带来了方便。
Objective:To design an environmental controller for motion disabled based on brain-computer interface(BCI). Method:The steady-state visually evoked potential recorded from subject′s scalp was processed to identify the targets that the user focused on. Then, the action command codes corresponding to the targets were transmitted to the executive unit,which carried out the specific functions.Result:With little training,the user could control the devices such as the on/off of the lamps and fans, to remotely control the television and air-conditioner, and to make a phone call. Conclusion: This system provides a novel BCI based environmental controller, which will be helpful for motion disabled in daily life.Author′s address Dept. of Electrical Engineering, Tshinghua University,Beijing,100084
