Abstract

EEG(Electroencephalogram) provides a possibility of communicating between a human and a computer, called BCI(brain computer interface). EEG evoked by a movement has been often used as a control command of a computer. This study is to predict human movements by EEG parameters showed significant consistency. Three undergraduate students were asked to move both hands and foots thirty times respectively. Each movement consisted of single and three consecutive movements. Their EEG signals were analyzed to obtained ERD(Event Related Desynchronization) and ERS(Event Related Synchronization). The results showed that ERD and ERS could be used as a significant classifier identifying either single movement or repetitive movement of human limbs. The number of repetition of movement could be used to various control commands of a computer.
