This paper introduces one of the young, energetic and rapidly growing research fields in biomedical engineering-Brain-computer interface (BCI) technology, which can provide augmentative communication and control capabilities to patients with severe motor disabilities. We summarize the first two international meetings for BCI, and present the most typical research fruits. The problems in current studies and the direction for future investigation are analyzed.
