Interactive Brainwave Visual Analyzer

The human forehead is the most developed part of the brain, it's shows personality. Like dolphins and cats, it's also called  "melon brain" and/or Third Eye. For example, to produce Alpha frequency (8 - 12 Hz) is easy to generate from the rear part of the brain, not easy to generate from the forehead. IBVA's very high quality amplifier & visualization technique can show Left & Right forehead brain wave activity changes very clearly in real time;  it can also show Left & Right brain wave phase coherence for each frequency. Coherence does not depend on brain power. In case it shows coherence, then we can say that the Third Eye is open this time.

Left & Right brain usually work independently, so coherence will happen randomly. But for the person who trains well his or her Third Eye, they can show coherence more continuously. In that case, the Left and Right brain can make a more clear image in the mind and/or make a path way to the mind's hyper space time dimension.
Then mind & brain are connected to hyper space time dimension and/or to our world.

IBVA can visualize brain wave in real time 3 D mapping; it can  also control many media such as QuickTime Movie, Sampling Sound, MIDI sound, 3 D sound position, Sound Effect. It can send messages in real time to other machines as well, such as PC, Lighting System, Laser System, Animation System, 3 D computer, graphics System, MP 4 computer System, MAX System. We can use Left & Right and Coherence brain wave information for all of these purposes - new Biofeedback experience.

The IBVA system has three models. One channel system, Two channel system and Two channel & coherence system.
One channel system shows forehead brain wave activity.
Two channel system can show left & right hemisphere brainwave, or two people's forehead brain wave in same time.

Two channel & coherence system use special modification version of transmitter, need to use PCI serial card, in case Mac doesn't have two serial ports. Receiver out put is serial.  


EASY TO CONNECT

Putting on head band, sensor will catch brainwaves, data will be sent from special transmitter  wirelessly. The receiver needs to be connected to your computer by cable.                
   
                                                          

receiver gets charged by computer, connect to LED very quickly. :

 

   1 ch head band with one channel transmitter.



The transmitter has brain wave as sound output from mini jack. Two channel brain wave can record into stereo line input of camcorder, MD & other recording devices.
In you are using 4 truck sounds camcorder, you can record two channel brain waves and stereo sound.
You don't need to use computer for this recording operation.
Later, to play back two channel brain waves and video image on Mac, connect recording device's line output to receiver's tape input & recording device's firewire, then connect to Mac firewire connector. To see video image on Mac, you need to use video application.

Added Open GL (most popular for 3D CG program interface),  to make FFT brainwave analysis results. This OpenGL FFT analysis can operate graph or light source in 3D by mouse operation. By this operation, you can not just see graph on the screen, you can see 3 D analysis graph  on upper front of the same screen. Dismissable brainwaves cause big signal, you can check from different position. OpenGLFFT analysis mode is prepared for 6 different type of displays to effect your eye sight.

This screen shot shows openGL FFT display on top.   Normal FFT display or Raw data display  on the back. It shows, right and left brainwave data in 2ch, coherence on the back, relative coherence in front. You can see these images from 3D angles, and you can control movie or sound.To  out put MIDI info, switch each frequency & amplitude.
