Model of biometric reflexions
2011
Project for “The Life. Science version”. Second internationally science-art festival, Moscow.
The main creative task of this work is an attempt to materialize the mechanisms of the human consciousness, our psycho-physiological processes and brain activity.
Groups of visitors can make a biofeedback connection with our art object in order to get a unique possibility to interact in a direct dialogue with their own psycho-physiological mechanism.
6 kinds of biofeedback devices
1) Photoplethysmography
This method allows to define the quantity of light in the infra-red range reflected (or absorbed) by blood vessels when illuminated.
2) Changes in skin electric conductivity
Galvanic skin reaction is a bioelectric reaction registered on the skin's surface.
The device measures the level of your emotional activity in real time.
3) Thermo-measurement
This device uses fast and high-precision measurements to define the change of temperature to within thousandths of a degree.
4) Brain blood supply measurement
The method of photoplethysmography allows to register pulse waves passing through the place where the sensor is set.
5) Measurement of brain activity of right and left hemispheres
A connection to the object allows to feel the domination of cerebral hemispheres. One can understand what part of the cerebrum is more active at the moment and even try to change it by thinking about different things.
6) Brain music
This station reads off data and reacts to the bio-activity of one’s brain - it detects alpha, beta and gamma waves.
