摘要:
视觉刺激器是刺激脑电信号的重要方式。为了满足想象左右手运动的脑机接口系统的特定需求,为其提供人机交互界面,采用了DirectShow、多线程和并口通信技术,在DirectShow中自定义过滤器,设计并实现了基于DirectShow的实时图像视觉刺激器。系统的开发工具是VC＋＋,运行环境是Windows,脑机接口的数据采集仪器为Biosemi公司生产的Active One多道生理信号采集系统。最后通过脑机接口实验证明：能在满足时间精度要求的前提下,完成图像刺激的控制、并口通信等功能,为想象运动脑电的效果提供
Abstract:
Visual stimulator is an important way to stimulate the brain signals.In order to meet the specific needs of brain-computer interface system for imaging left-right hands movement and provide human-computer interface for it,used DirectShow, multi-threading and parallel port communication,realized a self-defining filter in DirectShow,designed and implemented a real-time image visual stimulator based on DirectShow.The development tool of this system is VC＋＋,operating environment is Windows,data acquisition instrumentation for brain-computer interface is＂Active One＂multi-channel physiological signal acquisition system produced by Biosemi.Finally the brain-computer interface experiments proved that it completed the functions such as image stimulus control,parallel port communication and so on,satisfied the requirement of time accuracy,provided a good guarantee for the effect of EEG based imaging movement
