许多实验室已经开始开发脑机接口（BCI）系统，为患有严重运动障碍的人提供通信和控制能力。进一步的进展和实际应用的实现取决于对不同脑信号、记录方法、处理算法、输出格式和操作协议的系统评估和比较。然而，典型的脑机接口系统是专门为一种特定的脑机接口方法设计的，因此不适合对持续进展至关重要的系统研究。针对这一问题，我们开发了一个文档化的通用BCI研发平台BCI2000。BCI2000可以单独或组合任何脑信号、信号处理方法、输出设备和操作协议。本报告旨在向研究人员、生物医学工程师和计算机科学家描述BCI2000系统所基于的概念，并给出使用该系统成功实现BCI的示例。迄今为止，我们已经使用BCI2000为各种脑信号、处理方法和应用创建了BCI系统。数据表明，这些系统在线运行良好，BCI2000满足BCI系统严格的实时性要求。BCI2000大大减少了人工和成本，方便了不同脑机接口系统和其他心理生理实验的实施。它提供了完整的文件，并免费用于研究或教育目的，目前正被许多研究小组用于各种研究。
Many laboratories have begun to develop brain-computer interface (BCI) systems that provide communication and control capabilities to people with severe motor disabilities. Further progress and realization of practical applications depends on systematic evaluations and comparisons of different brain signals, recording methods, processing algorithms, output formats, and operating protocols. However, the typical BCI system is designed specifically for one particular BCI method and is, therefore, not suited to the systematic studies that are essential for continued progress. In response to this problem, we have developed a documented general-purpose BCI research and development platform called BCI2000. BCI2000 can incorporate alone or in combination any brain signals, signal processing methods, output devices, and operating protocols. This report is intended to describe to investigators, biomedical engineers, and computer scientists the concepts that the BCI2000 system is based upon and gives examples of successful BCI implementations using this system. To date, we have used BCI2000 to create BCI systems for a variety of brain signals, processing methods, and applications. The data show that these systems function well in online operation and that BCI2000 satisfies the stringent real-time requirements of BCI systems. By substantially reducing labor and cost, BCI2000 facilitates the implementation of different BCI systems and other psychophysiological experiments. It is available with full documentation and free of charge for research or educational purposes and is currently being used in a variety of studies by many research groups.
