wording what i am trying

Feedback system -through attending today's David class-
Charles and Rob are working on a kinetic output based on the units having their own internal connection with each other.
So with a sound input, I would like to focus on effecting this output by enhancing and diminishing its behavior like a volume control, or putting a variation in their behavior so that it possibly produces our own solution for manipulating the state of 2 separate spaces. I have made 3-4 prototypes and compared them to really understand different sensitivities of sound data based on different methods. I hope that this could possibly control the sensitivity of our project itself.

Conceptual Model

Conceptual Model, originally uploaded by thetarbre.

We would like to manipulate a special organization by creating a certain behavior of a partition panel based on its internal connection.
Units change their transparency through reading vibrations creating each other. (Piezo Element)
As the tool for reading ambient noise, the microphones would be set up in two separate rooms.
When analyzed and interpreted, this incoming noise data would act as a master control of the state of separate rooms by possibly enhancing or diminishing the behavior of the panel overall.

B_vibrationalSensors>>to charles and rob

The basic configuration of the Piezo element is shown here:
>>code

Listening to each other -revealing materiality through the vibrational interaction of each component-
We hope to make the interaction among each component of our output that would require a relatively small scale of input from each. So in parallel with working on sound input (that would be sensing a wider range of presence), the exploration of output based on input of the Piezo element would be good to start with.

Raw Piezo Element.
I heard that microphones are made of piezoelectric film. Those piezoelectric sensors consist of a small piezoceramic plate and electrode and are generally used to detect strain or very slight force changes. When bent, they produce varying voltage within a relatively ready-response.

ASM06_Arduino meets Processing...visualizing Potentiometer values

For dealing explicitly with the complexity of sound input, it is effective to visualize the data in processing. Here are the steps I made for letting Arduino talk to Processing.

->> Processing Serial Library
->> Arduino Play Ground / Arduino meets Processing / Potentiometer

[step1] ASM06_001AP-potValues It is a potentiometer value that has to be visualized here in its processing code. When the pot knob is turned, the incoming value gradually changes.

HYPOSURFACE

The piece Hyposurface is a facetted metallic surface that has potential to deform physically in response to electronic stimuli from the environment (movement, sound, light,etc). Driven by a bed of 896 pneumatic pistons, the dynamic 'terrains' are generated as real-time calculations.

The piece marks the transition from autoplastic (determinate) to alloplastic (interactive, indeterminate) space, a new species of reciprocal architecture.

The Aegis Hyposurface effectively links information systems with physical form to produce dynamically variable, tactile 'informatic' surfaces. Aegis is perhaps the world's first such dynamic screen.

Any digital input (microphone, keyboard, movement sensor) can trigger any physical output (a wave or pattern or word.)

design and the elastic mind

http://www.moma.org/exhibitions/2008/elasticmind/

In the past few decades, individuals have experienced dramatic changes in some of the most established dimensions of human life: time, space, matter, and individuality. Working across several time zones, traveling with relative ease between satellite maps and nanoscale images, gleefully drowning in information, acting fast in order to preserve some slow downtime, people cope daily with dozens of changes in scale. Minds adapt and acquire enough elasticity to be able to synthesize such abundance. One of design's most fundamental tasks is to stand between revolutions and life, and to help people deal with change. Designers have coped with these displacements by contributing thoughtful concepts that can provide guidance and ease as science and technology evolve. Several of them—the Mosaic graphic user's interface for the Internet, for instance—have truly changed the world. Design and the Elastic Mind is a survey of the latest developments in the field. It focuses on designers' ability to grasp momentous changes in technology, science, and social mores, changes that will demand or reflect major adjustments in human behavior, and convert them into objects and systems that people understand and use. The exhibition will highlight examples of successful translation of disruptive innovation, examples based on ongoing research, as well as reflections on the future responsibilities of design. Of particular interest will be the exploration of the relationship between design and science and the approach to scale. The exhibition will include objects, projects, and concepts offered by teams of designers, scientists, and engineers from all over the world, ranging from the nanoscale to the cosmological scale. The objects range from nanodevices to vehicles, from appliances to interfaces, and from pragmatic solutions for everyday use to provocative ideas meant to influence our future choices. The exhibition will be accompanied by a fully illustrated catalogue

Exit Art, 475 Tenth Ave. at 36th St.
Price: $5 suggested donation

Some of the most exciting scientific research deals with the brain, illuminating the mind's enigmatic inner-workings. Scientists are learning more about the complex network of operations that govern behavior, morality, language, spirituality, memory, perception and intelligence. These responses to outside phenomena often overlap, forming the layered judgments and reactions that texture experience. New technologies have also helped us to gain access to the space inside our heads, the center of consciousness, spirituality, sense, and illusion. We are learning, more and more, that the brain is indubitably the most intricate and mysterious territory of the human body. But what do artists have to say about the brain?
Exhibition features work by: Suzanne Anker, David Bowen, Steve Budington, Phil Buehler, Andrew Carnie, George Jenne, Daniel Margulies and Chris Sharp, Fernando Orellana and Brendan Burns, Jamie O'Shea, SERU, Devorah Sperber, Naho Taruishi, Dustin Wenzel.

Part of the BRAINWAVE NYC festival. BRAINWAVE asks how art, music, and meditation affect the brain and offers countless answers in more than a hundred public events, ranging from an exhibition of contemporary art and a cinema series to cutting-edge concerts, performances, talks, and panels.

This "only in New York" cultural festival is organized by six New York nonprofit organizations: Rubin Museum of Art, Exit Art, Science & the Arts at The Graduate Center of the City University of New York, The Philoctetes Center at the New York Psychoanalytic Institute, and the School of Visual Arts, in association with the American Museum of Natural History.
