A RESEARCH ON EEG (ELECTROENCEPHALOGRAM) PARAMETERS EVOKED BY HUMAN MOVEMENTS FOR BRAIN COMPUTER INTERFACES

Abstract

Computers have been communicated with users by keystroke, mouse-dragging or mouse-clicking that should be translated human intention to. Direct connection to computers has been attempted in terms of brain computer interface for providing disabled user with interface to computers without the detouring methods. This study is to determine EEG(Electroencephalogram) parameters significantly correlated with human movement that interfaces a computer. Three undergraduate students were asked single movements and three repetitive movements of a limb. Their EEG were analyzed to determine ERD(Event Related Desynchronization) and ERS(Event Related Synchronization). The results have showed the possibility of discriminating limb movement and repetitive movement from single movement using the determined ERD and ERS.
