A hybrid NIRS-EEG system for self-paced brain computer interface with online motor imagery

摘要

Background: For a self-paced motor imagery based brain computer interface (BCI), the system should be able to recognize the occurrence of a motor imagery, as well as the type of the motor imagery. However, because of the difficulty of detecting the occurrence of a motor imagery, general motor imagery based BCI studies have been focusing on the cued motor imagery paradigm.
