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

You Live and You Learn

The Kinect, mentioned in the previous post as something which would be an absolute life saver I managed to get my hands on one from the university. I was over joyed that they had one and thought all my problems would be solved, I was 100% wrong…just spent the last three hours typing away on Terminal and downloading different programs so that Processing could ready the Kinect and use it as an output, to find that it was NEVER going to work because the model number of the kit is too new. I needed ¬†an older version model, mine being 1473 and the one i need having to be 1414.
As you can imagine this is quite frustrating, putting a stunt on the work I was going to create.

But no worries I can still get round this; the whole Kinect idea is now dropped I am just going to use a normal webcam. The down side to this is the benefit of having the Kinect is it’s ability to recognise depth and people, saving me having to right the code I will find another way round this.

What I’m going to do now

The job now is to find a fix for this problem, already thinking about it whilst I slowly failed at terminal I will have to focus the camera to recognise movement rather that big shapes (like bodies), below is an example of what I wanted to achieve with the Kinect camera. What you are looking at is one picture (the middle) have the persons entire body being the blank space the particles being in motion around, the other is the reverse of this, body being the particles and the blank space being around. I can still do a basic idea of this which is going to be much simpler than what I planned.10931510_10204872979937564_2224866543232384509_nThe Fix


  • Colour
  • Motion
  • Lighting

I will be able to adapt a similar, but complete different interface.


  • Using the change of colours I will adapt the webcam to base the code of recognising colour, so imagine in the picture below the lines are red and the persons body is blue; when the blue overlaps the red you will see movement. Relating to the way I wanted the particles to move.


  • Having the Particles been replaced with colour (making colour the main focus) the next key aspect is motion; it is important to make sure that Motion is recognised when passers walk by, I will have to think about away of the colour not being static having it in a focus which shows the world moving even if it is not.


  • The use of lighting is something I could add to give this idea an extra sparking, having different tones of colour to create a different perspective when being output, I will look into this more later.
