摘要： One embodiment of the user authentication method using brainwave signal according to imagined speech includes extracting and storing characteristic information of a first brainwave signal generated by an imagined speech of a first user based on preset imagined speech induction information provided to the first user by the user authentication apparatus, and determining whether a second user matches the first user by extracting characteristic information of a second brainwave signal generated by an imagined speech of the second user, based on preset imagined speech induction information provided to the second user, comparing the characteristic information of the first brainwave signal with the characteristic information of the second brainwave signal stored according to the extracting and storing, and analyzing a result of the comparing by the user authentication apparatus.

摘要： The present invention relates to a brain-computer interface system and a method for recognizing a conversation intention of a user using the same in addition to inferring the waveform of word sound intended by a user from an imagined speech brainwave associated with a word intended by a user, since the user can intuitively recognize the sentence he/she wants to speak through the imagined speech by classifying words that are most relevant to the imagined speech brainwave of the user in a database in which a word often used by the user or frequently used in a specific situation is stored and by generating a sentence intended by the user by recognizing the words classified in this way, it is possible to perform communication by only thoughts of the user.
