// Input component
1.webcam feed
2.catalogue of physical distractions
-library (sneezing scratching coughing twirling)
-domestic (pink bathrobe, fidgety baby, voyeuristic signaling)
-institutional (pathological actions)

// Processing component
Webcam library in Processing, watching for a catalogue of triggered motion
Signal cases sent to Arduino environment

// Output component
arduino/flexinol
Sensitivity of motion read on neutral backdrop (bluescreen allegory)
Active enhancement of motion cases results in matching/evolving deformations.
Output of ambient noise (crackling) embedded in material

// Scale of a single "module”
scale of a human hand, repeated to personal partition scale

// Number of modules you will create
2D grid of cells, repeated to a goal of 4*6.
This represents one active partition at full scale

// Siting (vertical, horizontal, indoor, outdoor, in a quiet environment, etc.)
The site is really a condition; the condition is about sensitivity to and for occupancy.
One site is the library, where the misuse of research space is transmitted and amplified to rectify disruptive behavior. Another site is in the home in an east-facing room, where a baby’s crib could modulate sunlight in response to the fidgety behavior of the disturbed child. Another is in the mental institution, where the unacceptable pathological motions of a specific patient triggers sound and motion as a subtle alarm.

// The "twist" of the project
the twist is in the evolving output from multiple input cases. For instance, the kinetic response is different when a library user is twirling his pen, vs. when he scratches his head.

// Vendors of all materials you will have to buy
the hardware and software is in place; main considerations are materiality. Plastics have so far been the most successful, and can be found in all shapes and sizes on canal st.

// List of technical issues and tests you will have to conduct in the next five weeks
sectional reading; problem of planar arrangement. We’ll need to fine-tune the relationship of depth (the camera watches a user from some distance, who is then some distance in front of the plane of deformation)
Defining threshold for successive movement will also be an issue
A. is there a 1 to 1 relationship between motion and motion, where a 3 second movement results in three seconds of reaction?
B. is there an evolving behavior which updates and compounds, where the first action results in an equal action, and a second action results in a doubling of reaction?
1 = 1
2 = 3
3 = 7
4 = 15
n = n(1)=n(2)=n(3)=n(4)=n(n)

subverting rfids

2006-11-13T16:11:00.000-08:00

Our project, with less- and more-desperate alternates:

Project: GSAPP students who respond to our posters will be able, with the wave of a tag on the Avery 3 ½ floor, to bring up their portfolio images (or whatever images they’re like) on the floor’s flat-screen monitor, erasing the previous waver’s image.

Alternate L: The three of us, with a few lucky others, will have either portfolio images or simply text notes (“evan wuz here”) on the terrace widescreen, like above but more limited.

Alternate M: The three of us, with anyone who owes us favors, will set up the same game described above, but on a studio computer, with the rfid reader attached to a studio desk-wall, so that the reader could be tripped from either side of the wall.

Twist / Interesting:
The project exploits the outstanding characteristics of rfids as sensors: their unique identification and their subtlety, while still working within the project’s financial and programmatic limits (short range, passive tags, single reader). The project inverts the typical use of the rifd as a covert tool by which institutions track individuals or items, converting them to a tool by which individuals overtly and competitively assert their identities.

Input: Phidgets RFID reader

Processing: Flash script

Single module: One computer & screen, one rfid reader, multiple rfid tags

Number of final modules: One, with multiple tags

Vendors: The only potential additional products are rfid tags from phidgets.com. Tags cost $1-$3 each, and a prior delivery took four days.

Siting: Indoors. The possibility of using the terrace computer and monitor has been confirmed, but the details haven’t been worked out.

Our primary challenge will be to get Flash to recognize the rfid reader's output. Given our experience with flash, we expect the coding to be, while not light, relatively managable and predictable.

Metal Tags--Mecayla, Ahmed, and Kalina

2006-11-13T14:10:00.000-08:00

COMPONENTS:

Input: Metal Actuator Tag
Processing: Metal Detector (Coils) and electronic circuit processing board
Output: L.E.D. or single flexinol wire (swappable with many simple output components)

SYSTEM:

Modules:
The system has two major components—the metal detector and the metal actuator tag. Each component is an autonomous parasite-like element that is small, versatile, and can be applied to a variety of architectural surfaces. The modules are meant to be a low-tech alternative to RFID sensors or any responsive information giving sensor system.

Site:
The system is not site specific. As a “parasite” system, the components can be attached to or become part of many architectural surfaces. Examples of site situations could include:
Retail stores—Tracking sales or items
Bars/Lounges—Interactive environments
Libraries—Tracking books
Museum Exhibits—Counting people or creating responsive exhibits

The “Twist”:
The metal detector component is not used to detect the presence of random metal in or on people and things, but is used to “read” the presence of pre-specified objects or people marked with a specific actuator. In this scenario, the two “parasites” (the metal detector and the metal actuator tag) work as a controlled system and can be used for a variety of functional and/or entertaining purposes in a number of architectural conditions (rather than being left to random and unspecified triggering of the system). The human uses the system as an interactive environment for their specific needs, therefore redefining the negative connotation of metal detectors.

Vendors:
Metal Detector (Dismantled)—RadioShack
Metal Detector Casing—Materials to be determined
Various Metals—Art supply stores

Technical Issues and Tests:
Determine one or more metal types to which the metal detector can be specific so as to not register random nearby metals.
Design casing for metal detector coils and processing board.
Design metal actuators to be cheap, disposable, small, and convenient.
Test “parasites” at multiple locations and for multiple uses.
Refine details and produce extra modules.

the tension of the flexinal wire.
how to control the open and close of the tube.

We reconsider the problems that came to us during the process. One of the biggest one is the friction of material. We choose plastic tubes to be our cells but they do not perform as we thought. They couldn't form a effective back and force movement. The original idea is to use the minimum input to achieve maximum output. We disign some movement which motivated by just a few cells.

Another big issue is the tension oh the flexinol wire. We couldn't come out a way to maintain the tension. Once it lose the tension, it will become less effective, even zero offset.

Now we adjust a little since one of us drop this class. We keep the basic idea of using little movement to achieve maximum performance. We change the material from plastic tubes to paper and the destination is to build a light fixture which can adjust by the sensors to create some relative effect from human movement.

Also see FAQ on Visual Basic

How do I get Phidgets RFID reader to run through Visual Basic?
First install the Phidgets Library, then open the pre-written VB code.

Download and install the phidgets library here:
www.phidgets.com>downloads>phidgets20Downloads>phidget20.msi

From the same page, download ‘phidget20examples.zip’
After unzipping, open MS Visual Basic.

On the file menu, click ‘open project’ and, from the folder that you’ve just unzipped, open: examples>production examples>Visual Basic>PhidgetRFIDExamples>rfid-simple>rfid_simple

N.B.: You need to use ‘open project’ to maintain links within an established project. “open” will not work. Nor will double clicking from outside the program.
N.B.: Currently, the phidgets21 folder contains enough Visual Basic script to make it look like things are working, but not enough to actually make things work.

Why does the script automatically update when I open it, and why does it still not run?
The language used by version 2006 is slightly different from the language used by version 6.0, but it (supposedly) updates the scripts to the new language.

When you debug the scripts, you’ll find that it gets hung up on certain lines. Look to the programming notes, probably in red, and always set off with an apostrophe.

What is the difference between the executable programs in the phidgets “Visual Basic” folder and the VB project files?
The executable files are the compiled versions of the VB project files. That is, they are programs in themselves rather than scripts, so you can use them to try out the hardware, but you can’t change them. Scripts, on the other hand, can be edited and recompiled.

When I run any of the phidgets VB scripts, the light will go on and off, but it won’t read any RFIDs. WTF?
Yeah, WTF.

Also see FAQ on Visual Basic

How do I get the Basic Stamp board to run through Visual Basic?
First install the drivers, then open the provided interface script in VB.

1. Install the drivers by installing the basic stamp editor on the computer. Use either of the two Windows editors here:
http://www.parallax.com/html_pages/downloads/software/software_basic_stamp.asp
The drivers will be installed once the programs are installed.

2. Open the ‘stampsendVB’ project here:

Visual Basic FAQ

2006-10-30T20:52:00.000-08:00

If you're thinking about using Visual Basic, here are the basics.

What is MS Visual Basic?
A relatively easy scripting language based on the original, straightforward BASIC scripting language. It’s an ‘object oriented language,’ which means that the starting point of its programming is an object, generally a window, on which a scripter will put buttons, textboxes, etc., then write script to give those sub-objects functions.

How do I get MS Visual Basic?
Currently (October 2006) you can download VisualBasic Express for free from Microsoft here: http://msdn.microsoft.com/vstudio/express/vb/download/

However, Microsoft is expected to start charging for it before the end of the year. Currently Microsoft asks users to register, but they won’t ask you to pay.

Just download it and install it. Currently at the GSAPP you’ll need to write tech support to get permission to install outside software on your in-house computer.

note: If you plan to reference compiled information such as databases in your scripts, you’ll want to install the SQL server when prompted during installation.

What's the difference between a VB script and a program?
Like most programming languages, VB reads the scripts you write, then, when you ask it to, it compiles the script into a program that you can run just like any other program in Windows. VB 2005, however has a very useful debug feature that lets you run the program as if it were already compiled.

How do I learn the basics of VB?
The help menu’s ‘guided tour’ has a well-done fundamentals of programming tutorial.
Also useful is http://www.vbtutor.net/.

2006-10-30T17:12:00.000-08:00

We decided to measure the voltage from the metal detector from Prototype 3. As we suspected it was not high enough to move the flexinol wire. Here we show it at it's highest,
0.09 Volts.

We purchased a new metal detector with a larger coil and which runs on two 9V batteries. We immediately tested the voltage from the new detector. Our highest result was 8.2 Volts, much larger than the previous.

AD592 Calibration

The formula that relates the temperature to the time measured by RCTIME is a reciprocal:in this case TK is Kelvin temperature.

rct = constant/TK or TK = constant/rct

In order to calibrate the sensor, we need to find the constant for this particular setup. To do this, the AD592 sensor must be put in a location where you know the temperatureexactly. A good choice is an ice bath at 0 C, 273 K.

With an ice bath reference, TK = 273, the constant will be (rearranging the previous equation):

constant = 273 * rct

We have to put the probe into an ice bath, let it stabilize, read the value of rct, and multiply to find the constant.

Ice bath preparation for calibration:
-The melting point of ice made with pure water is a physical constant: zero degrees Celsius,32 degrees Fahrenheit, 273 Kelvin (Or 273.14 if you want to push the precision).

You can get the best results if the ice and water mixture is:
􀀹 made with crushed ice made from distilled water;
􀀹 is held in a vacuum thermos bottle with a narrow mouth;
􀀹 stirred gently while making the measurement; and
􀀹 at least 5 cm of wire is submersed above the sensor probe tip.

Lacking a thermos bottle, you can substitute a well-insulated foam container. Careful preparation is very important if you want to achieve good results in the calibration! Watch until the reading settles down to a steady value, to equilibrium.
√ Place the AD592 temperature probe into the ice bath.
√ Run the program AD592.bs2.
√ Watch the Debug Terminal until the readings equilibrate (become steady).
√ Record the reading for rtc.
rtc = ___________.
√ Take that number and multiply it times 273. This is your AD592 calibration constant.
rtc x 273 = ___________.
Be aware that this constant is specific for this sensor, this BASIC Stamp, and this capacitor.
√ Now round off the constant to the nearest 10, and drop the final digit (a zero). This should be a five-digit number. This will be the value of Kal you need to substitute in the program.
Kal = __________.
√ Put this value in your AD592.bs2 program in place of the 15300 "default" value. (marked in red above)
√ Re-run the program. You should see TK and TC show the temperature of the calibration bath--273 Kelvin, 0 Celsius.

We are not sure how the switch button fits into things and we didn't get the LED working to go on and off but at least got the readings of temperature on the computer. As we are also interested in other sensors we are not going to spend any more time on this one just yet to finish figuring out how to get the LED on and off but there is potential there to put in variables by which to make it go on and off.

The '0' in the right hand column is the degrees in Celsius once calibrated in an iced glass of water.

INITIAL CONCEPT FOR OUTPUT FOCUS

a b

a_This study was an investigation of the notion of 'slip space'. We wanted to focus on the output of our system and how the internal elements of the system redistribute themselves into non-determinate patterns.

b_We then decided to alter the system to see what the results would be if the external binding structure was flexible as opposed to rigid. The result was a more dynamic output.

PROTOTYPE/MATERIAL STUDIES

The first series of prototype studies tested out three types of materials and their specific properties within a flexible structure.

PROTOTYPE 1a-Foam

RESULTS-Foam ended up being a difficult material due to its friction. Movement bowed out and often ended up bursting out of the frame.

PROTOYPE 1b-Styrene

RESULTS- The styrene worked great. The friction was low and it allowed for a lot of 'slip' movement internally along with working well with the external frame.

PROTOTYPE 1c-Rubber

RESULTS-This material was similar to the foam in regards to issues with friction. The friction was too great thus making the movement of the output difficult to achieve.

Each of these cells could be treated as an individual unit and then be aggregated into a larger system. The styrene/plastic would be the best material to accomplish this.

PROTOTYPE 2

We then attempted to weave in some of the Flexinol wire and test its movement by directly hooking it up to the 9V battery.

RESULTS-We ran into issues with the wire becoming too hot and then slightly melting the plastic. The movement was also not as great as we would have liked to to the gauge of the wire.

PROTOTYPE 3

This protype uses a board and a simple structure which is attached to a select few cells to allow the movement.

RESULTS-Issues with the material of the structure and the gauge of the wire came up again. The piano wire ended up bending and the Flexinol wire was too thin and ended up snapping.

photo of the arduino board and output setups.

also take a peek at this link to a video showing the attempt at 3 simultaneous outputs (flexinol) trough the arduino board using some silly song on gil's totally sweet, new computer. yeah!

on a more serious note- our failure to successfully trip 3 outputs simultaneously has to do with the power distribution limits of the arduino board. we are currently looking for an exterior power source independent of the arduino which will plug directly into the bread board and distribute power to each output channel. it's going to be killer- along with a new source code on maxmsp jitter which will tell our little buddy to attack all three positions, or more, in well thought-out strategery! your sound will mess you up... potentially.

Metal Detection - Prototype 3

2006-10-17T12:17:00.000-07:00

1. After our failed attempt at the makeshift metal detector, we decided to order a kit. The kit consisted of a search coil connected to a small, simple processing board with the reference coil attached as well as a LED indicator light. There was also an attachment for a "buzzer" which we decided not to use. Instead, we connected the positive and negative output wires to our flexinol actuator directly.

Results: When the flexinol was connected, nothing in the system operated. Weird.

2. We then connected the positive and negative lead wires to our micro controller in place of the PIR sensor (and the flexinol actuator connected again to the micro controller).

Results: The system responds (we know this because of the LED indicator), however, the LED is weakened in brightness and the flexinol does not respond. We think we need to amplify the output voltage somehow. (The processing board from the kit has too many resistors.) ]

3. The last test was to directly connect another LED in place of the microcontroller or flexinol. (This is what is pictured above.)

Results: The additional LED worked just the same as the LED on the processing board.

If anyone is interested, here's info on how metal detectors work and how to build them:

Metal Detection - Prototype 2

2006-10-17T11:59:00.000-07:00

Our first attempt at building a metal detecting system used some basic principles of electricity. Here, the two coils of wire produce an electromagnetic field when a current is passed through them. These fields yield a certain frequency and when metal enters one of the fields, it changes its frequency. Both coils are to be tuned to the same frequency where one stays as a reference and the other is used for metal detection. Normally, a beat is produced when the frequency of the search coil changes (due to metal interference). Our goal was to use this input and when metal was detected our flexinol should have flexed.

The result: the wire flexed once and stayed in that position. There are a number of variables we tried in wiring the system, but all yielded the same result.

a light show...

file: sensor 100206
By flipping the "cleared" and "tripped" commands in the code, such that the "cleared" is first and, at the same time, flipping the PIR value so that "0" comes before "1", the lights start in the "on" position [lit] and then turn off when the sensor is triggered. After triggering, on the 3rd second it turns back to the "on" position.

By taking the "counter" argument out (counter = counter +1), the lights blink twice. Keeping the argument and altering it like this: counter = counter +10, the lights blink three times.

file: 3 lights
the next step was to create a condition in which the lights would respnd differently to the same trigger. the starting position is with the red and green lights on. when detecting a movement they switch off and the yellow one lights, then they come back to the first position again (red and green on). If the detected movement is more intense, the process is repeated a second time.

_subscript : prototype02

2006-10-03T13:10:00.000-07:00

dealing with the possibilities of physical reactions brought upon by different properties of sound, we must consider numerous parameters. first what is to react, then how it will react.

prototype two is the exploration into the geometries and their kinetic ranges. to what extent will materials such as paper and chipboard move while being acted upon by a one dimensional action- their capabilities in themselves and versus each other.

how do we want this 'living architecture' to move? its reaction is our vision of an intrinsic, personal perception- how do we see sound as participating in space... with people; then, in turn, how do we want others to react to our perception of anticipated reactions. user creates sound simultaneously- we create possible reactions in physical, mechanical form- coinciding, is the manifestation of a directed interaction. ironic question posed: what are the unexpected changes?

RESEARCH PROPOSAL

ASE (Available Space Expansion)

Team: Lola Rodriguez

Orama Siamseranee

Sara Valente

Stan Vinokur

+PROJECT:

Our proposal focuses on the transformation of a flat public surface (ie. Sidewalk). The surface responds to the need of more space in crowded area by registering static presence and passing movement by creating a usable topography.

+RESEARCH AGENDA:
Using weight sensors as our input, we will investigate different ways of creating a responsive topography(output).

We will investigate various ways of producing the topographic changes using litinol, panel systems, inflatable devices, and structural feasibility.

+ COMMON ARCHITECTURAL ELEMENT
We will design a ground covering system.

+ MOVEMENT
We will create a landscape that has the ability to change form in response to different kinds of occupation (static and moving).

Our research will focus on mechanical systems that will make the changes in form possible.

+ SPATIAL IMPACT

The change in form of the surface will transform a space used for passing to a hangout space.

+ REALIZATION
We will build a section of a functional prototype.

+RESEARCH TOPIC PROPOSAL:

For the ASE research we will start investigating and testing sensors, pressure and noise specifically, and their processing; this will last the firsts 2/3 weeks.

The rest of the semester will be focused on the ‘output’ research, investigating on:

-Materials (plastic, silicone, wood, metal?)

-Forms (square, hexagon, Voronoi tessellation?) defined by movement and efficient arrangement of sensors

-Movement (surface composed by flexinol wires or mechanical system)

The project is based on the fact that cities are becoming more and more crowded every year and free space sometimes is just not enough; squares, plazas, sidewalks (public space in general) is used for commuting and for short/long permanence; our physical environment should respond specifically to this two conditions most of all when Architecture nowadays has already the ability to respond to fast changes of uses, technology, typologies, culture, economy..

We propose to create a surface that is able to increase its area (responding to the amount of people present in the space) upwards, downwards or sideways, depending on the space possibilities, and to reshape the experience of waiting and walking on public spaces.

+ RESEARCH TOPIC: Responsive habitation is the result of intelligent space. In this case, we will investigate auditory input in public space, creating (from a flat state?) variants on performance space or shelter. We are interested in the feedback loop of a space transformed by sound, and the resulting modification of acoustic character which becomes embedded in the system. Further fascinations:
Materiality/immateriality.
Logic of the fold in modulating acoustic character?
Light as visual proxy for environmental control?

+ RESEARCH AGENDA:Collect information on the following:

-Robust and responsive materials, able to maximize the capabilities of a Flexinol-driven motion system.

-choice of ambient environmental/ active input sensors: acoustic(Piezo?/Vibration?), temperature(HOBO), temperature+humidity(Sensirion SHT1X) Flexiforce pressure sensor, Photoresistor (luminance), PIR sensor, etc.

+ COMMON ARCHITECTURAL ELEMENT- Translation of limited flex-wire output (via mechanical amplification) to pronounced enclosure transformation. Material transformation enhanced by immaterial transformation (light/shadow/color range)
+ MOVEMENT- We will devise a structural/skeletal system, reliant on the contraction provided by flexinol shape-memory wires, which will act to modulate certain environmental factors such as daylight, sound performance, ventilation, etc.
- Immaterial modulation: LED color range connected to a range of sonic inputs.

- movement research: studies into mechanical advantage/lever arm for maximum translation. We also must ask the question; “what makes the Flexinol wire preferable to servo motors?”+ SPATIAL IMPACT- Enhanced awareness of environmental factors reflected in enclosure system; automated performance functions with (possible) occupant override.+ REALIZATION- scale study models
- investigation of intelligent materials over time (plastic hinges, visualization of repetitive stress)

2006-09-26T12:42:00.000-07:00

Research Agenda:

Overview:

It is our intention to utilize radio frequency identification technology (RFID’s) in order to activate and engage intelligent, anticipatory architectural responses.

Fundamentals and Potential:

Traditionally used in retail and security, RFIDs are a low-cost, unintrusive, and efficient means of distributing information, allowing for the tracking and cataloguing of products and personnel. An RFID system involves a reader that writes and reads information on tag. Tags can be as small as half a grain of sand, cheap as ten cents, and have an indefinite lifespan.

With the widespread implementation of RFIDs, the control of large numbers of people is possible. We will look at the potential of RFID input to intelligently and dynamically, in real time, create spatial organization in crowds, specifically through the manipulation of thresholds, portals, and pathways.

Movement:

Our research will focus on the distribution and collection of RFID tag data, however we will consider outputs including manipulation of:
- gates
- turnstiles
- varying passage width
- varying floor slope
- integrated lighting controls and cues

Realization:

1. get reader to read tags
2. write code to allow intelligent interpretation of tag information
3. provoke simple outputs
4. explore potential for economies of scale

RESEARCH PROPOSAL v_1.0
9.26.06

AGENDA

_Element We intend to explore the spatial and structural potential of the responsive kinetic systems of mutational floor elements

_Movement We intend to research and produce a true responsive kinetic system that does indeed move as well as change physical form and volume by transforming from the floor plane into a 3-dimensional element.

_Space Our responsive kinetic system will not be limited to surface transformation, but will affect the spatial and volumetric characteristics of the immediate environment in response to human activity and occupation. This study will focus on interior rather than exterior conditions.

_Realization To fully explore comprehend the implications of a such a research project, it is essential that the physical construction be realized at full scale. We have thus decided to limit the scope of this investigation to the human scale.

_Materiality We intend to explore not only the unconventional use of conventional materials, as well as unconventional materials themselves. The material, particular that which comes in physical contact with people, is the experiential interface, and will therefore be a large focus for this investigation.

PROPOSAL

The “use” of physical space most often requires an active experience. Space often simply becomes a repository for furniture and other effects, and frequently is “used” only at by the behavior and activities of the inhabitant. We intend to explore the possibilities of an passive occupation of space, that is to say, a space which responds to presence of its occupants by transforming itself into functional elements. While the information detected and read by sensors embedded in the space will vary depending on the type of space and different human characteristics, we will be limiting our investigation to the exploration of what and how the space will passively transform itself. We will be using a simple infrared sensor as “binary” input device that detect the presence or absence of an inhabitant, allowing us to focus our resources primarily on the materials and implementation of the output function of the system.

By focusing on output potential, we intend to explore an array of different types of actuators, ranging from servo motors to pneumatics. This portion of the research will test the feasibility and functionality of the different actuators in order to find the most efficient method to transform the surface of the floor. We will simultaneously explore the potential of different materials to act as the interface between the occupant and the mechanism. These materials will include silicon sheets, cast silicon, flexible wood veneers, and a variety of textiles.

Imagine an expansive and open space such as a gallery whose floor plane would only be interrupted when the floor itself detected that an occupant needed to sit; at which point a mass would emerge from the floor to accommodate the need to rest.The goal of this research is to develop a component of a spatial system that, upon detecting the presence of an occupant, will transform, or “grow”, itself into a usable furniture element. The objective is to create a comfortable and functional sofa-type element that will rise from the floor when needed, and recede back into the floor when the occupant rises and walks away. We find this intriguing and fascinating as an exercise of “making something from nothing”.

PROPOSAL DESCRIPTION

The idea of this project starts with the exploration of the labyrinth as a representation of the complexity of the mind.

If we remember Daedal Labyrinth the center would represent the desire of getting an answer of the complexity of a reality that we can not control. Once we know how to get in we can find again the way back, we can now control the space and therefore to know what was unknown, but can we really have that control?

We would like to explore within this idea how space can be experienced and perceived in different ways, mentally and physically. Thinking about the condition of the labyrinth, we could imagine it as an endless space but framed at the same time.

This endless condition could be represented as a field or grid within a border. A framed space that the visitor can experiment discovering the different possibilities of paths within this labyrinth, activated with his own movement in it. The answer of this movement could be a certain intensity of light, configuration or path that can give him a clue or the possibility to choose among different options.

The control of the space would be in reality the mental representation of it, if we play at the same time with the partial control of what we really see.

At this point, we could look at it from two different points of view:

_ The experience being inside the labyrinth, and thus, activating it.

_ On the other hand, the experience of being outside, knowing the answer, recognizing where the people are.

GENESIS

First Cluster

One (1) SENSOR
One (1) PROGRAM (code)
One (1) BREADBOARD
Five (5) LED light

This set up will allow for experimentation with the construct and an investigation into the combination of the output indicators (LED). This will be expanded upon until a scale can be reached that mimics our earlier reference to the labyrinth.

LIVING ARCHITECTURE: RESEARCH AGENDA

Objective: to construct a responsive urban operator that mediates the relationship of public to its environment while existing as part of a network at an urban scale.

Architectural Element: We are going to investigate fabric tensile structures (eg. Umbrellas, mobiles, sails, kites, meteorological measurement tools) and investigate how these tools might withstand environmental impacts in their various states, and how these particular form variations are created.

Movement: We will construct an entity that can be deployed at an urban scale so that the sum will have a cumulative effect in providing an awareness of one’s surrounding environment. The final form will be responsive to particular environmental conditions that will expand/ contract and result in the reflection and negotiation of public space in accordance with the inputs.

Spatial Impact: This change will be sensed or experienced at a human scale while having a multiplicity of results. The object will have an educational awareness aspect for the individual that alters with the physical shift. There is also a larger objective of consisting as a part of an urban scale network.

Realization: We plan to build one prototype that would essentially exist in the proposed network so that our objectives may be realized by the human interactor.

RESEARCH TOPIC PROPOSAL

We plan to complete weekly functioning prototypes that investigate both the environmental shifts that will create the most responsive final model (whether it be temperature, rain, sunshine or wind) while simultaneously using form and easily accessed materials to test inherent natural properties to work towards the ideal final model. (eg, Latex, rubber, paper, wire frame, fabric)

We will investigate the practical use of cost effective and readily available vibration, humidity and pH sensors (all stocked through Parallax) to choose the best input sensor. We hope to find our ideal combination of outputs through experimenting with concepts of education/ awareness (information) display methods, orientation, and environmental protection/ shelter.

We will produce a light construction final model that can be situated outside to react to the chosen environmental conditions, or inside with simulated conditions. The design will bring a unique urban design approach to this project providing an alternative in overall scale (network) and potential implementation opportunities within the public realm.

//_COMMON ARCHITECTURAL ELEMENT

The architectural element of exploration for subscript will be surfaces, primarily vertical but may grow into elements that inhabit multiple planar fields.

//_MOVEMENT

Movement of the subscript system will consist of an organization of sensors and outputs that have individually “dumb” responsive reactions, but originate from highly tuned audio inputs. The system will respond according to multiple audio properties [such as wave frequency, amplitude, vibration] within unitized embedded elements that are interconnected. Although this relies upon a precise analysis of input, the output of the system is the main direction of subscript. [subscript is confident in its abilities to capture and tune audio input through MAX/MSP/JITTER.]

//_SPATIAL IMPACT

The subscript environment strives for full immersion and response. Its surfaces will be kinetic altering its apertures and surface extension through linear actuated conversion. The surface will not be defined by the planarity of a wall, floor, or ceiling but will be continuous and differentiated in form and reaction (sound reflection).

//_REALIZATION

subscript intends to build and install the final result. subscript will use all tools at their disposal to realize the final element, including other integrative software such as MAX/MSP/JITTER, generative components, and Maya. In addition to physical production, subscript will not be limited by contributions from external software; these tools will be used as additive enhancers of and for performance of the project.

//_research topic proposal

//_output

The primary research topic undertaken by subscript will be within the topic of output. Initial plans for prototyping areas include aperture, linear movement conversion, and topical extension. Output will also be, in some circumstances, the input of the physical reactions to sound and its reflection from the installation.

Research Agenda:
Our intention is to design and create a multifunctional wall surface which reacts to the presence of people and translates their presence into a deformation of the surface and/or a change in lighting effects. This surface and light interactive installation will serve the purpose of conveying information for security and safety concerns as well as for a interactive installations We hope to apply these installations in a variety of public spaces in order to test results and refine the applications. This installation could be used at any/all sites, places and/or buildings where security is an issue such as: airports, train stations, government buildings, school buildings, places of worship, national monuments, landmarks, etc.

Research Proposal:
Our proposal is to arrange an array of metal sensors and possibly other sensors that will detect the presence and movement of people and process that information through the installation. We will focus however, on the output of these sensors in the form of surface movement and the reaction of light emitting diodes (L.E.D.’s). The installation will be made of a material that is flexible in nature and perhaps translucent, perforated or wire framed to allow for an added effect of lighting change.

There will be a horizontal array of motion detectors that will read the movement of people passing by and process that motion which will be output as deformation(s) on a surface that is equal in length to the array of motion detectors. Depending on the type of surface being used, the deformation(s) can range from undulations, compressions, stretches, pushes, pulls, influxes, etc.

Along with translating motion through deformations, the installation will convey information through the change in lighting effects. Linked to the motion detectors will be metal detectors that read the presence of metal much like the wands used for security purposes. The detection of metal will be processed and output through the variation of colors of light. For example, if there is no metal detected the output light color could be blue, if there is metal detected the light color could be red; the more metal detected, the more intense the light would be. Research will be conducted on different light sources for this purpose and how light reacts to electrical pulses. In addition, we will experiment with a variety of surface materials such as metal clad, woven textile matter, and plastics.
Finally, it is also our goal to use low cost, low energy, and sustainable materials and power sources in order to create an architectural installation which is self-sustaining and low maintenance.

ResearchAgenda _v1.0

Architectural Element
We will try to create a variation on the ceiling grid that can be dynamic and able to fluctuate patterns.

Movement
Limiting ourselves to the contraction and extension of the Flexonal wire, we will try to create a system that allows non-linear movement

Environmental Impact
A series of physical deformations and realignment of elements within a closed system to create an impact on the quality of light within a space.

Realization
We will build a series of physical models exploring different material, exploiting their physical characteristics to work in a system of our design.

ResearchTopic _v1.0
We intend to focus our research in on the output of a system. Looking at algae formation and taking osmotic pressure as a point of departure, we are trying to look at how a series of semi-rigid bodies of various sizes will respond and redistribute itself when agitated into non-determinate movement.

Potential
Lighting, Architectural components, Boundary of Space ( ex. Pattern of wall.) .etc.

The investigation of this application could be an interesting contribution to kinetic architecture by studying a system which has a rigid internal structure, but that still allows for flexibility and free form movement that responds to human interaction.
