Coherent Detected Periodic Brainwave Computer Control

提供的空间 目的是为有严重肌肉控制的用户演示脑波通信 残疾人士。基本的技术方法将是使用周期性脑电波的相干检测， 利用相干检测系统的能力来拒绝来自肌肉和 随机脑电波信号。将使用免提CyberLink计算机控制系统作为基本 构建块。将对软件进行修改，以实现完全相干检测。20名受试者， 严重的肌肉控制障碍将被用来回答以下问题：(I)受试者能否 训练以产生周期信号；(Ii)这些周期信号的信噪比是否足以 允许可靠的两级决策；(3)受试者是否可以接受训练以控制幅度或 这些周期信号的频率和(Iv)可以有意识地混合非相干信号 增强学习周期性信号的产生。这代表了计算机的一种革命性方法 进入。由用户产生的控制信号将独立于非自愿肌肉活动 对于那些没有其他控制方法的人来说，这种方法作为一种计算机访问方法很有吸引力 由于肌肉的不自主活动，如痉挛。以前锁定的用户现在将 能够接触到计算机、通信和控制。

SPACE PROVIDED The objective is to demonstrate brainwave communication for users with severe muscle control disabilities. The basic technical approach will be to employ coherent detection of periodic brain waves, taking advantage of the ability of a coherent detection system to reject interference from muscle and random brainwave signals. The hands-free Cyberlink computer control system will be used as the basic building block. Software will be modified to operate with full coherent detection. Twenty subjects with severe muscle control disabilities will be used to answer the following questions: (i) can subjects be trained to generate periodic signals; (ii) is the signal-to-noise ratio of these periodic signals sufficient to allow reliable two-level decisions; (iii) can subjects be trained to control either the amplitude or frequency of these periodic signals and (iv) can the conscious blending of non-coherent signals enhance learning periodic signal generation. This represents a revolutionary approach to computer access. Control signals generated by the user will be independent of involuntary muscle activity making this method attractive as a computer access method for those with no other method of control due to involuntary muscle activity such as spasticity. Users that were previously locked-in, would now have access to computers, communication and control.
