Brain wave correction device and brain wave correction

Abstract

At a body part other than the head region, brain wave signals having high accuracy are obtained. A brain wave correction device includes: a transfer function obtaining unit that, based on a brain wave signal at a first body part and a brain wave signal at a second body part different than the first body part at the time when a user has a predetermined thought, obtains a transfer function for brain wave signals between the body parts; a brain wave obtaining unit that obtains a brain wave signal at the second body part; a brain wave correcting unit that corrects, based on the transfer function, the brain wave signal obtained at the second body part and calculates a corrected head-region brain wave signal; and a brain wave comparing unit that, based on the corrected head-region brain wave signal and based on a reference brain wave signal obtained in advance at the first body part, estimates the thought arising in the user.
