Method for processing a brain wave signal and brain computer interface

摘要

Method and brain computer interface for processing a brain wave signal of a subject using a brain wave detector. One or more stimuli are applied to the subject which each include a pseudo random noise component. The brain wave signal is detected and mental processing of the one or more stimuli is tracked by correlating the pseudo random noise component and the brain wave signal.

1. A method for processing a brain wave signal obtained from a person using a brain wave detector, the method comprising:
applying at least one stimuli to the person, wherein each of the at least one stimuli comprises a spread spectrum pseudo random noise component; detecting a brain wave signal; and then tracking mental processing of the at least one stimuli by correlating the spread spectrum pseudo random noise component and the brain wave signal, wherein tracking of the at least one stimuli comprises: transforming the spread spectrum pseudo random noise component by providing a prediction of a brain wave signal for a specific spread spectrum pseudo random noise component by decomposition of a recorded brain wave signal using contributions associated with rising and falling transitions in the specific spread spectrum pseudo random noise component; and controlling a device based on said prediction of the brain wave signal.
