wording what i am trying
Wednesday, March 26th, 2008Feedback 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.

Friday, March 14th, 2008The 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
Thursday, March 6th, 2008For 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.

HYPOSURFACE
Monday, March 3rd, 2008
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.)
