NERVE USER INTERFACE DEVICE, A NERVE USER INTERFACE METHOD THEREOF, AND A DEVICE FOR MEASURING BRAIN ACTIVITY, CAPABLE OF DETERMINING THE INTENTION OF A USER BY PHOTON-TISSUE INTERACTION

摘要

PURPOSE: A nerve user interface device, a nerve user interface method thereof, and a device for measuring brain activity are provided to determine the intention of the user by measuring the brain activity without invasion.;CONSTITUTION: A light irradiation unit(11) irradiates a photon to the cerebral cortex. An optical detector(12) detects the photon outputted to the outside after mutual reaction with the cerebral cortex. The optical detector detects the variation of the physical quantity of the photon by measuring the scattering spectrum and the near infrared absorption of the photon. An analysis unit(13) determines the intention of the user by analyzing the variation of the physical quantity of the photon and generating the brain activity data. The analysis unit determines the intention of the user using a correlation coefficient comparison algorithm.;COPYRIGHT KIPO 2010
