Provided are an apparatus and a method for recognizing positive/negative intention using a fine change of gamma wave of a brainwave comprising the steps of detecting the brainwave from a head of a user, receiving and amplifying the brainwave detected from the step of detecting the brainwave, converting the amplified analog brainwave to one of a digital type, and recognizing the positive/negative intention of the user by detecting the fine change of the gamma wave of the brainwave in the digital type, which is transmitted from the A/D converting portion, whereby it is possible to implement an application of a real time interface and minimizes inconvenience for the user, and it requires no separate user practice.

Disclosed are an apparatus and method for controlling vehicle brake using the brain waves. A driver controls the brake using the characteristic of the brain waves appearing before the driver's movement in the course of stepping on the brake pedal for braking in a dangerous condition. Therefore, the brake can be operated faster, and a condition where the brake is operated in an unwanted situation is prevented to prevent a traffic accident in advance. Further, the present invention does not require a driver's specific intentional behavior or psychological action except for natural behavior for braking (behavior to step on the brake pedal). Accordingly, the present invention makes a user convenient and is suitable for an ordinary person.

The present invention to provide a method for determining positive and negative emotional states by using a relative power in a subband of a specific frequency band increases or decreases in the course of time. In order to realize the above object, the present invention determines positive and negative emotional states by using a relative power in a subband of a specific frequency band increases or decreases with the lapse of time. The present invention performs a Fourier transform for a unit time not an entire response time regarding a stimulus, and can be used in real time by using a time-frequency analysis method continuously executed with the lapse of time.
