An interactive installation work by David Fodel and Sarah Soriano at Gallery 023, University of Denver, Denver, USA on May 9th, 2009.
The title of the work is taken from two previous ideas.
Technoetic is a word coined by Roy Ascott in 2003 and meant to denote a path by which we might understand the effects of technology on consciousness.
Rainforest is a work created by David Tudor which dates back to about 1965. In Tudors work physical objects and sculptural forms are activated using audio transducers, causing those objects to resonate. The objects themselves modulated the incoming audio, transforming the sound, based on the material.
In the Technoetic Rainforest, we introduce human consciousness into the feedback loop that is created between materials and electronic signal.
A system is constructed which exhibits certain sonic and visual behavior in its undisturbed state. The system consists of cameras, computer vision software, and a multichannel sound creation and distribution matrix.
Simple tones create vibrations and modulations by exciting audio transducers, attached to large sheets of plate steel.
A small vessel, filled with water, is also activated by an audio transducer. This causes the water in the vessel to create patterns and distortions in the waters surface. These patterns are analyzed using a camera and blob detection software.
Blob detection is typically used for extracting usable information from image data, normally object recognition and object tracking. The association of this technology and its visible activity on the projected screen serve to foreground an implied "intelligence" within the system.
The intelligence gathered on the incoming image is further used to modulate the audio signals, creating a subtle yet sophisticated, ecologically balanced feedback loop.
Once a person enters the room, their presence begins to intercede into the variations in the audible sounds, their bodies serving to absorb or reflect certain frequencies within the space. Their shadows in the space, or the interruption of the camera's view of the vibrating water further disturb the modulating steady state of the system.
These subtle interactions and their results become part of the feedback system which drives yet further variations into the system. In this way the system becomes an analog for basic consciousness, in that it is self-reflective.
In decoding the phenomenal world through technological apparatus, we externalize the process of modeling experience, of our own construction of consciousness. As the system evolves, our impact, understanding and actions evolve with it.
