Θ Theta: Sensory Feedback System is an interactive installation for two people that generates images in the mind of one user with the help of the neuronal activity of a second user. It is a feedback loop that both users close by wearing each one a EEG device and looking into blinking lights that are synchronized to the frequency of the other user's neural oscillation. The lights blink so fast that the mind tries to give them meaning creating patterns and forms that resemble real objects, scenes or landscapes.
Neural activity is codified in light and both brains communicate with each other using a non-human language. It is a syntax composed of frequency and amplitude of bioelectrical signals that travel through cellular membranes because of visual stimulation.
