Down in the Open Space

Here is the first image of a person walking by the system, as you can see the particles are constantly moving which is what I wanted to be portrayed; showing that we are not the only things which are moving in the world, even if you can’t see it, it doesn’t mean it hasn’t got a response, the camera is showing this.

The problem here is the way the particles are responding to each other; because the camera has to pick up a much bigger space there aren’t enough particles to cause a big enough response to react to the man walking by. This can easily be fixed by adding more particles.


Here I flipped the code adding lines, as seen previously in my designs. The benefit of this was the reaction the camera had towards the person on screen as well ash the particles responding much better to his movements. Expressing what I wanted to a much better light.

Here is someone reacting to the system, I think the same person who had noticed the work and come back to see what happens. The person was eager to see how the particles reacted by doing star jumps and moving closer to the camera, this helped show the space been left blank where the persons body was, but the particles around still staying in motion.


This is the biggest jump with the code, having made the particles bigger and also reversing the negative space as seen in previous experiment I wanted to see how to bigger space would react. It in fact not being beneficial to the initial idea at all, the particles don’t have the motion which always shows movement anymore and the bold colours of the persons body isn’t strong enough to draw attention towards the particles.

I would describe this as the worst out come for the digital environment; it lead to the camera lagging once again and the particle where not responding enough to represent my concept, but the colours are nice and you can see the Tardis very well.


Overall it was a shame that there weren’t many people in the foyer at the time because my response may have been more deeming, but the way the almost particle system symbolised the space looked very nice and portrays my concept ideally, but not to the standard I want.

Edited code for second installation below –V–

Capture video;
boolean cheatScreen;

String letterOrder =
  "------------------------------------------" +
char[] letters;

float[] bright;
char[] chars;

PFont font;
float fontSize = 1.8;

void setup() {
  size(640, 480);

  // This the default video input, see the GettingStartedCapture 
  // example if it creates an error
  video = new Capture(this, 160, 120);
  // Start capturing the images from the camera

That One PARTicle That Just Can’t Keep Up

for (int x = 0; x < video.width; x++) {
int pixelColor = video.pixels[index];

int r = (pixelColor >> 16) & 0xff;
int g = (pixelColor >> 8) & 0xff;
int b = pixelColor & 0xff;

Here I have made a slight changes to the colour, I have changed the attributes from “r,g,b,” to “h,s,b,”. The reason for this is to add a clearer image to what is been projected, allowing people to see what is going better. At the moment I feel the way the particles are looking doesn’t look clear enough and show the blank spot where the person is well enough, changing these attributes will hopefully improve this.

for (int x = 0; x < video.width; x++) {
int pixelColor = video.pixels[index];

int h = (pixelColor >> 16) & 0xff;
int s = (pixelColor >> 8) & 0xff;
int b = pixelColor & 0xff;

Also changing the font size again, this time too 2.5.


As you can see I have encountered a little problem

theproblemThe problem I have encountered here is the camera cannot keep up with my movements, this is a big deal because of the pace people walk through Weymouth House, they will not notice that there bodies are being blanked out. Trying to fix this problem I added in a fps command;


This had no response to the work; nothing changed so I fluctuated between higher and lower frame rates and this still had no difference….So I tried cutting the amount of letters (particles) in half to reduce the collisions between them, again this had no difference. This problem is a tricky one to figure out, so I’m going to move from w119 and head down to the walking space and see if this makes any difference.

openspaceWhat you’re seeing here is the first view of the production in the Weymouth House walk through; me stepping away from to webcam to see if it is clear that I am standing there. The lag on the image isn’t as bad as it was up in W119, that could be due to the wider every of space, I did also reduce the size of the particles to allow more space for movement, hence dark spots.

I’ve Made A Decision

I’ve decided to use more than one of the code manipulations in this space, considered as further experimentation I am going to explain it as; “which code reacts better to the bigger environment.”

I Found Something

Doing my sketches and scrolling through examples I have come across something.


Jan 24, 2015 15:02I’ve hit a stroke of luck here, this piece being one of the examples of Processing it has all the aspects I am looking for;

Colour, Motion and Light

Here the colours are being replaced with ‘letters’ and they are hitting against each other to show constant reaction, this is the effect I want to try and portray (showing constant motion). From what I understand (what I see without looking at the code) the letters have slight tints dependents on the lighting in the room, but it’s not a big feature, the biggest feature here is the letters acting as the image. Very similar to the way particles would act.

I am going to develop on these letters and see where it could go. The reason for this being it’s structured way of portraying what the camera can see; it’s showing another way of seeing life and to me it looks quite like a particle system relating back to what I want my Concept to be. I could try and adapt these letters in other formats, replacing them with little dots may give the best portrayal of particles.
