ADAPTIVE BRAIN-COMPUTER INTERFACE DEVICE CAPABLE OF IMPROVING NUMBER OF COMMANDS AND MESSAGES THAT CAN BE INPUTTED PER HOUR

摘要

PURPOSE: An adaptive brain-computer interface device is provided to accurately find a command that a user wants in as fast as possible by determining the order of stimulation adaptively in accordance with the situation. ;CONSTITUTION: An stimulation generation device(100) creates stimulation and stimulates a user. A signal collection device(200) records a brainwave signal of a user which is generated by the stimulation. A preprocessing device(300) extracts the property of P300 for the stimulation from the brainwave signal. An interpretation device(400) determines the existence of the P300 from the extracted signal of the preprocessing device. A stimulation sequence determination device(500) decides the order of stimulation by choosing the optimal stimulation for the current state.;COPYRIGHT KIPO 2011
