BRAIN WAVE INTERFACE SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a brain wave interface system which is small in the physical labor of a user, and which is high in an operation speed.

SOLUTION: A display 12 on which a user keeps an eye is configured to display at least a flicker stimulus whose visual pattern is switched by any frequency between 40 Hz and 100 Hz. An electrode E is put on the head of the user, and a brain wave signal detection part 21 searches a brain wave signal including a constancy visual induction potential signal on the basis of a signal from the electrode E. A frequency feature analysis part 31 analyzes the frequency feature of the brain signal, and a visual stimulus determination part 32 determines the type of a visual stimulus on which the user keeps an eye on the basis of the frequency feature.
