Abstract: PURPOSE: A brain bio-feedback system and a controlling method thereof are provided to extract pure brain wave elements and display a measured value by separating elements of stability from brain wave signals. CONSTITUTION: A brain wave sensing unit(10) measures brain waves of four channels by using an electrode sensor of a head band and converts the brain waves to electric signals. A brain wave element extraction unit(20) separates the brain wave signals of four channels into four independent elements. A signal processing unit(22) produces an alpha wave spectrum of a pure brain wave from the independent elements. A display(26) outputs a measuring result of a brain wave according to an alpha wave spectrum ratio to graphics or data values. An auditory driving unit(28) provides an auditory stimulus to a testee. A microprocessor(24) is used for perform a control operation for outputting the measured result to the display and operating the auditory driving unit according to the measured result.
