__________________________M E T R O L I N E project_______________________________

METROLINE project is based on the observation of people using the subway of New York City, from the moment you get inside a car.

The idea is to re-direct people's attention to this anthropomorphic figures made of cardboard that would be seated on the cars seats, among people (in betweenrush hours), and will narrate something.

ACTION :

Main action :

-get in the car.

-get out the car.

GENERAL PATTERNS :

a- search for a seat

b- make the experience a "useful" one.

COMMON PATTERNS :

a- if seat ---------place stuff

-------------------look for a gadget (i-pod, book, newspaper, water, cosmetics...)

b- if no seat -----hold a bar

-------------------look others

>>>see .mov

Observating how people behave when travelling on the subway, made me think about how used people are to not expect anything "out of the rule" through this experience.

since it's a monotone trip (timing, sounds, people's faces...) the unexpectable scene of having this shape seated beside you...blah....

>>>see armory show pic

GOAL :

- Catch people's attention inside the car, into something out of themselves.

- Hear the METROLINE story-----

POSSIBILITIES OF BUILDING THE CHARACTERS (4 - 5) :

-as a cardboard antropomorphic character>>>see ex.>>>more using same drawings patterns as shown :

the important thing, if using this kind of AESTHETICS, is that it has to be evident to show "patterns" of drawing (as patterns of behaviour), or even a description on some space of the character, describing the steps of "how to ..." (build, behave, draw...)>>>directions >>>more >>>and more

POSSIBILITIES OF NARRATION :

2 possibilities ----------------------------------------------------------------

a- recording of reading of my first code. drawing on space (icm class - "saturnpigcat"->>> see code)

b- what it is to live in a 2D world. People as drawings, sketches of persons. In sculpture, you start from sketches or drawings to a 3D model, an object. This would be all the opposite; bring a person, a 3D "object" into a 2D world, the character...

c- reading the "how to draw" a human figure...

TECHNOLOGY TO BE USED :

-Servo motor --------make a moving part of the cardboard shape.

-Proximity sensor----that detect when someone is near, so to start the "speech"

-Cd player and speakers.

LINK 2-----------------------------------------------------------------first approach

PROCCESS :

I decided to build a mock up to see the visual effect, since this will be the main attention focus of people in the subway. (more handy? put prints on top of the cardboard?)

Considering the X and Y axis (the code reading) and how's a drawing among people, on real space, the idea of building a "cross" like figure would be good. Every decition here in this item, will be based on this drawings:

So I put together 2 different patterns that said what the perfect proportions of the body where, and i drew a human figure. The reading that people should hear might be this:

(instead of the code)...

---------------------------------------------LOOKS LIKE :

SENSOR (some research about the ultrasonic distance sensor, it might be a good one for my project)---------------------------------------------------------------there are too many!

Ultrasonic Distance Sensor (#28015) provides precise, non-contact distance measurements from about 3 cm (1.2 inches) to 3 meters (3.3 yards). It is very easy to connect to BASIC Stamp ® or Javelin Stamp microcontrollers, requiring only one I/O pin. The PING))) sensor works by transmitting an ultrasonic (well above human hearing range) burst and providing an output pulse that corresponds to the time required for the burst echo to return to the sensor. By measuring the echo pulse width the distance to target can easily be calculated. Features • Supply Voltage – 5 VDC • Supply Current – 30 mA typ; 35 mA max • Range – 3 cm to 3 m (1.2 in to 3.3 yrds) • Input Trigger – positive TTL pulse, 2 uS min, 5 μs typ. • Echo Pulse – positive TTL pulse, 115 uS to 18.5 ms • Echo Hold-off – 750 μs from fall of Trigger pulse • Burst Frequency – 40 kHz for 200 μs • Burst Indicator LED shows sensor activity • Delay before next measurement – 200 μs • Size – 22 mm H x 46 mm W x 16 mm D (0.84 in x 1.8 in x 0.6 in)

The idea of making a foldable human scale "object", fitted very well with the idea of making a "foldable company", this is, something you could carry, that was light, your size, always "available", but also, disposable.....

Origami models were a very good resource to show how folding an object behaved on reality, human scale size.

I decided to print out the schematic above of the "perfect human figure" in order to have the object for real.

the interaction with the prototype, was suppose to work, besides the sensor and the cd audio, since the "foldable" was the perfect company, as shown:

FUTURE WORK :

There still a lot to achieve here. I plan to finish the programming and make it work, since my final idea is to put METROLINE PROJECT on the subway of NYC, hopefully a couple of them. The statement of "proportions of the human figure", happens to be very mechanical to me, the same as the patterns that people use in the subway, so I find it's coherent.

I would like to use an ultrasonic sensor, after make the er work first. I might not ask anybody, since having too many opinions, definitely affects the work.

Finally, hope to reinforce some concepts during the summer break, and finish METROLINE PROJECT, although it should be consider a work in progress or a lab project.
