The ultimate goal of brain-computer interface (BCI) technology is to provide communication and control capacities to people with severe motor disabilities. BCI research at the Wadsworth Center focuses primarily on noninvasive, electroencephalography (EEG)-based BCI methods. We have shown that people, including those with severe motor disabilities, can learn to use sensorimotor rhythms (SMRs) to move a cursor rapidly and accurately in one or two dimensions. We have also improved P300-based BCI operation. We are now translating this laboratory-proven BCI technology into a system that can be used by severely disabled people in their homes with minimal ongoing technical oversight. To accomplish this, we have: improved our general-purpose BCI software (BCI2000); improved online adaptation and feature translation for SMR-based BCI operation; improved the accuracy and bandwidth of P300-based BCI operation; reduced the complexity of system hardware and software and begun to evaluate home system use in appropriate users. These developments have resulted in prototype systems for every day use in people's homes.
脑机接口（BCI）技术的最终目标是为严重运动功能障碍者提供沟通和控制能力。 Wadsworth中心的BCI研究主要集中在基于脑电图（EEG）的非侵入性BCI方法上。我们已经证明，包括严重运动功能障碍者在内的人们可以学会利用感觉运动节律（SMR）在一维或二维空间中快速准确地移动光标。我们还改进了基于P300的BCI操作。我们现在正在将这种经过实验室验证的BCI技术转化为一种系统，使严重残疾人士能够在家庭中使用，且只需最少的持续技术监督。为实现这一目标，我们：改进了通用BCI软件（BCI2000）；改进了基于SMR的BCI操作的在线适应性和特征转换；提高了基于P300的BCI操作的准确性和带宽；降低了系统硬件和软件的复杂性，并开始评估合适用户对家庭系统的使用情况。这些进展已产生了供人们在家中日常使用的原型系统。
