Sonic Electronic Graffiti. This installation was presented at the University of Barcelona in Jully 2006 and at Politecnico de Milano University in December 2006.
Design, direction, software and hardware by André Rangel.
Graffonic is a result from the technical process of production of an hyper-tool materialized under the form of an installation. This reactive work of art which I now present will be seen on a video projection, under the control of a video sign analysis system that cover all of the projection area. The user's movement is quantified in numerical data which will be the intelligible message for the machine. Accordingly, using its relative cognitive ability (supported by algorythmic processes), it will provide an audiovisual answer. The computer's answer is grounded on a process of generative design in order to create an esthetical reflex on a real time scale. This installation was presented at the University of Barcelona in Jully 2006 and at Politecnico de Milano University in December 2006..

Interactivity/Interface
In reference to interface and interactivity, although we recognize
that technology offers room to numerous and variable possibilities,
the concept of interactivity to which my work relates is no more
than a zone where the physical and the biological directly interact
with the abstract and the immaterial. This system allows the machine
to give the users control upon the application with reference
to the positioning of their hand on the plane. Interaction becomes
communication or even "conversation".[1]
I may also add a concept of interactivity related to the artistic
field. Interactivity provides a mean to stimulate the power of
imagination through the opening of new points of view, not by
physical experience but otherwise with the resource to new strategies
of interactive media[2], in which visitants are
the performers of the artistic work.
It is important to mention the concept of interface in relation
to interactivity. In this regard, it is convenient to remember
David Rockeby saying according to which if someone reacts intuitively
to an audio or visual event, a closed circuit is created in which
music and movement slowly unify themselves.[3]
Metaconception/Generative design
My personal experience with metadesigner Johny de Kam made me
more sensitive to the concept of Generative Design. Generative
Design lies on generative systems that suggest an alternative
approach to the production of images, making possible the autonomous
creation or the mathematical generation of hundreds or even thousands
of images.
The meta-artist acts simultaneously both as a guide and as an
aesthetical decider, concentrating not in the image in itself
but rather on the structure that produces the image.
Generative art refers to any artistic practice in which the artist
creates a process, such as a set of rules of a natural language,
a computer program, a machine or another mechanism, which is then
placed functioning with a certain degree of autonomy, fostering
or resulting in a complete work of art. In a certain way all humans
are also generative systems, and in that way all art is generative.
In this context, the word generative art refers to artificial
generative art.
General objectives
This installation pretends to be a space open to participation,
leaving always the last decisions to the users before the final
result of this work.
"Grafonic" is an installation that results from a work
presented by me at Juliols summer course at Barcelona, July 2006.
The content users/generators will be able to experience and explore
the encounter with the machine in a human's scale physical place.
In this way, real and virtual confront themselves completing the
meaning of my installation.
I intend that it should be used as a piece of urban furniture
with entertaining purposes. Thus, the project might function as
a kind of laboratory to the study of human behavior in the shape
of a space free to the interaction with digital space.
This is a performance in which users define the content and the
variability of the control, as I have mentioned before.

- Bongers refers that the classic interaction loop man/machine
may begin when the user wants to activate the system (in this
t, electronic). The system is controlled by the user through inputs,
the system processes the information and then presents a result.
The human perceives the information presented by the system and
then processes it again exercising control.
