発明の名称 (英語) Brain-computer interface system suitable for synchronizing one or more nonlinear dynamical systems with the brain acritivity of a person NEW
発明の概要(英語) Brain-computer interface systems aim to extract purposeful commands from physiological signals, such as the electroencephalogram, usually for assisting a disabled user in performing useful actions. The present invention pertains to such a system with increased accuracy and flexibility. Rather than being processed directly, the recorded signals are fed to one or more nonlinear dynamical systems driven by them and realized physically or simulated numerically. Commands are then extracted from the temporal activity of these systems rather than directly from the recorded signals. By means of insightful choice of the system type, parameters and coupling scheme, this approach can reveal and enhance the features of physiological activity that are relevant to command decoding, and attenuate all the others, beyond what is possible based on the state of the art.
