BRAIN WAVE DETECTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a device that does not cause a user and/or persons around to feel "troublesomeness" or "discomfort" for a change in light in brain wave detection that can be used for a BMI device utilizing steady state visually evoked potential (SSVEP).SOLUTION: A brain wave detecting device includes a target light emitter for emitting target light disposed at a position that can be visually recognized by a user, brain wave detection means for detecting a brain wave of the user, and steady state visually evoked potential detection means for detecting the presence of steady state visually evoked potential generated in the brain wave when the user visually recognizes the target light emitted by the target light emitter. The target light is the light whose color characteristics change repetitively in a change width that is not discriminated by a human.
