I chose this example to illustrate that it isn’t such a big deal for children to express that they don’t have knowledge about something, but I think, as we get older (and more ’specialised’) it can become increasingly difficult (and socially embarrassing) to admit that our knowledge or ability is in some way inadequate.

This very lo-fi demo brought up some interesting questions about what exactly the project is trying to do.  In the above example – wearers draw or write on the back of their lanyard something which they want to learn about and then they are in control of when (and to whom) it is revealed.  This is akin to the kind of ’speed-dating’ or ’social-networking’ games which already take place within conference environments and is not really the type of interaction I’m trying to get at…

The device which I am building would not be activated by the wearer – instead it would be activated by the presence of others members of the community and it would *involuntarily* reveal inadequacies (or short-comings) in the wearer’s knowledge or ability.

Progress…

1.  Arduino —> Programmable Display

I used this LCD display:
http://www.coolcomponents.co.uk/catalog/product_info.php?cPath=45_71&products_id=151

And this tutorial helped a lot: http://www.arduinoprojects.com/node/13

Problems:

* need to make secure connection to LCD

* need to control contrast of LCD

Code already called the LiquidCrystal library at setup and interfaced seven of the arduino digital pins to the LCD:

// include the library code:
#include <LiquidCrystal.h>
// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(2, 3, 4, 9, 10, 11, 12);

I put the wire controlling the LCDs contrast (pin 3 on the datasheet excerpt below) into the arduino digital pin 5:

// contrast variable to digital pin 5
const int contrastPin = 5;

And then established the best contrast level for this 16×2 LCD using PWM (which runs from 0-255) via analogWrite – 118 seemed a good value:

//PWM value
analogWrite(contrastPin, 118);
//info http://arduino.cc/en/Tutorial/PWM

* need to work with Arduino Nano

but also does not seem to work :-(

4.  (received vibration motor – have not yet integrated into programme)

5.  Cut out a simple housing on the laser cutter to demo the concept and give an example of layout:

IR transmitter and receiver mounted above and below electronic display.  (I added a button to the bottom right which would allow the device to be triggered ‘manually’ by the wearer themselves.)*

*added later – in retrospect, the last minute addition of a ‘manual’ button, allowing the wearer to trigger the device themselves is totally unnecessary and undermines the concept of the device.

Technology = ‘prosthesis’ – not ‘literal’ artificial body parts – legs / hearts / breast implants – but objects which extend and transmit an individual’s conception of self in a way which is more than mere metaphor.

For my second assignment of the DOING module (presentated 17/3/2010) I had an idea, which would work in a conceptually opposite direction:

I have begun to outline concerns regarding tokenistic ‘one click’ digital engagement with legal and political frameworks thru handheld devices and the web (see previous posts.)  Further to this, I am also alert and suspicious of the current ‘mania’ regarding the use of gesture, touch and interaction with digital technology and especially in relation to the new breed of ’smart phones,’ and home physical computing (iPhone, Nintendo Wii etc.)

And, since the title of the project brief was ‘Mirrors,’ I decided to work on something which could bring to the fore this fascination with our own (seemingly) reflected action.

I had an idea to develop some kind of application which could reflect and make apparent the (pathetic) nature of a users contribution.  This application would require a constant interaction in order to provide a very limited and basic feedback.

My idea was to use Processing to create a sketch for a potential iPhone application which would do NOTHING UNLESS SHAKEN.  On shaking the device, a looped video file will play but then, if the user stops shaking, the video will pause.  Since the video is set to loop after only a few seconds this constant user effort will return a very limited response.

In terms of the media file, I wanted something silly and banal and I decided to use a video of someone playing the maracas.  A suitable media file, which I found in the incredible Prelinger Archives and sampled in order to produce the loop, can be viewed here:  http://www.archive.org/details/Havana-Madri_2

Below is my sketch – which is extremely simple – embedding the video and overlaying an image of an iPhone.  Mouse movement over the sketch is used for the purpose of the sketch as an analogous ‘demo’ signal in place of actual, physical iPhone ’shaking.’

video = new Movie(this, “MaracusLOOP169QVGAzoomed.mov”);
video.loop();
}

// callback function (below) seemed to result in undesired flickering
//so used ‘if’ function within ‘draw’

//void movieEvent(Movie m) {
// m.read();
//image(video,140,40);

void draw(){

//call video
if (video.available()){
video.read();
}

//video image positioned at desired location
image(video,40,40);

//boolean statement below checks for mouse movement
if (pmouseX == mouseX && pmouseY == mouseY){
video.speed(0);
}else{
video.speed(1);
}

//overlay image inserted at the very end so that it is on top
image(img, 0,0);
}

My Digital Media Research Masters Final Project will require a theoretical understanding of the alliances and interactions between law and digital technologies and it is my hope that this learning can be aided through discussion with both the designers, programmers and theorists resident in Culture Lab and also legal academics across at the Law School.

Tomorrow, at 2pm, I’ll be making a presentation to a PHD Research group at Newcastle Law School to introduce my research and thinking regarding areas where technology, art and law appear to intersect:

Title: Interfacing with Law

John O’Shea is working on an AHRC Research Project at Newcastle University’s Culture Lab proposing and prototyping new kinds of technological ‘interface’ between citizen and law.
The convergence of digital-media collaboration tools (such as wikis), G.P.S. enabled mobile devices, and ubiquitous social networking technologies present not only new challenges for legislation but also new possibilities for governments, corporations, communities and citizens to interact with legal frameworks.
John will present examples from his current avenues of research and open up a discussion regarding the implications of current technologies for citizens and the legal profession.

As well as discussing current examples of “Web 2.0″ technologically enabled initiatives between citizens, government and legislation I would also like to direct some focus onto instances where the two streams – technology and law  – seem to merge and hybridise instigating problematic scenarios brought about neither by citizen nor government BUT instead simply through the advancement and free proliferation of new technologies.

Real practical examples of these unanticipated pairings are often evidenced in the tabloid media:

Top: Recorded data in G.P.S. systems (potential evidence of wrong-doing) causing headaches for businesses and lawyers.
Below: Low unit cost of fingerprint scanners is enabling new, non governmental, identification schemes.
Bottom: To counter thieves, designers technologically ensure that mobile phone owners keep their device on their person at all times (again using G.P.S.)

In each of the three story examples, technological innovation is portrayed in an unswervingly positive light and, although each of these developments could have very obvious implications for the privacy of individuals involved, these concerns are not voiced.

In his ISEA2009 keynote, Clive Van Heerden of the Phillips Technology ‘Design Probes’ division discussed these kind of throwaway news articles and used the phrase ‘weak signals’ to liken them to a kind of cultural indicator.

This idea has parity with one of Marshall Mcluhan’s 1969 conceptions of the role of art and artists in relation to technology:

I think of art, at its most significant as a DEW line, a DISTANT EARLY WARNING system that can always be relied on to tell the old culture what is beginning to happen to it.

More info regarding DISTANT EARLY WARNING at this excellent site HERE!

My thoughts have returned to the unusual Prenzlauer Berg gravestone and I have decided to make a model.  The black outline will be cut from leftover acrylic plastic in the workshop and the design element (in red above) will be engraved (is engraved the right word – sounds quite grand -  anyway, it will be cut also but not all of the way through.)

Having already made an approximation of the spirograph design I have worked with Processing’s bezier() function to make an outline shape similar to that of the original stone.  It took some time to understand how to programme the curves but once the bezier principle is understood it is actually very simple.  Basically, the curve is constructed through combining both sets of co-ordinates for the construction lines (in red below).

This stone was the most interesting art object that I encountered during my visit to Berlin’s Transmediale.10.

The dead individual (whom this stone is representing) presents us with a subtle, final-word: a challenge to living-beings.

The ‘optical illusion’ of physical depth against this pristine, flat, surface evidences our flawed and filtered sensory apparatus and disturbs any complacency regarding attempts at understanding the nature of perception (and by extension: space; consciousness; life; and death…)

I have begun working with the design from the stone to test out some ideas in Processing.

(My initial code for the above outline is shared here.)

int a;

void setup()
{

size(500, 500);
background(255);
smooth();
noFill();
stroke(0);
a = 10;

ellipseMode(CORNER);

ellipse(125, 250, 250, 250);

for(int a=0;a<360;a=a+10)
{
pushMatrix();
// move the origin to the pivot point);
translate(250,250);
// then pivot the grid
rotate(radians(a));

// and draw the square at the origin
noFill();
ellipse(-125, 0, 250, 250);
popMatrix();
}
}
