摘　　要：本文针对脑瘫(CP)患儿这一特殊群体,研究设计了基于脑机接口(BCI)技术的表情辅助训练系统。系统采用的脑机接口设备是Emotiv EPOC+,通过WebSocket通信协议获取和传递脑电信号,并且使用小波包变换对信号进行处理,获取信号的特征值;使用V-REP仿真软件设计仿真四轮小车,将获取到的特征值用于控制仿真小车实现不同方向的运动,以达到吸引患儿的注意力、提高训练效果的目的。设定了带有图片的人机交互界面增强引导患儿注意力。通过与医院康复师现场实验,验证了该技术的可行性,可为相关设备研发提供技术储备。An expression-assisted brain-computer interface(BCI)-based training system is designed for children with cerebral palsy(CP)in this paper.The system uses Emotiv EPOC+(brain-computer interface)to acquire and transmit EEG signals through the WebSocket communication protocol.The wavelet packet transform is adopted to process the signals and obtain the eigenvalues of the signals.V-REP simulation software is used to design a simulated four-wheeled cart,and the eigenvalues obtained are used to control the movement of the simulated cart in different directions to attract the child’s attention.The human-computer interaction interface with pictures is set to enhance and guide children’s attention.The feasibility of the modified technology is verified through field experiments with the hospital rehabilitation division,providing technical reserves for the research and development of related equipment.
