Brain-computer interface (BCI) is designed to provide rich and powerful command signals for assistive devices by decoding user's intention directly from brain signals in a real-time way. Recently, both theoretic and practical aspects of BCI technology have rapidly developed and become increasingly mature. More application scenarios of BCI technology have been demonstrated as well. This review summarizes the important achievements and events in hardware, algorithm, paradigm, and application in the BCI field in 2019-2020 and discusses its development trend.
