Abstract:

BACKGROUND: Brain-computer interfaces (BCI) provide a direct communication and control channel for sending messages and instructions from brain to external computers or other electronic devices. Using the non-muscular channel, subjects with severe neuromuscular dysfunction can directly express their thought and manipulate the external devices without using human language and actions. This greatly enhances the ability of these subjects to manage external event and improves their quality of life.
OBJECTIVE: To summarize latest research advances and problems in the BCI and discuss the research direction of BCI.
METHODS: The literatures on BCI were searched on the PubMed database published from January 1990 to December 2009 with the key words “brain-computer interface, rehabilitation” in English. In addition, the related articles were also searched on CNKI-KNS published between January 1990 and December 2009 with the key words “brain-computer interface, signal processing and electroencephalography” in Chinese.
RESULTS AND CONCLUSION: Researches of BCI system is still at a developing stage. There are some disadvantages, such as low rate of communications instability, especially for algorithm improvement and selection of signal processing.
