ICM Final– Glitchtchtchitch.

Manipulation and surveillance visualization.

Featured in ITP Winter Show 2013(See all the pics!).

Glitchtchtchitch is a live interactive installation showing multiple short-lived fault in a system. By bringing out the imperfection of technology with massive pixels manipulation, sound distortion, and multiple screens display, Glitchtchtchitch visualize the transient fault and the incapability of communication. Although mainly sending serious messages, with the effect of headless illusions, heads displacement, and delay, it leaves audience undergoing an experience without too much pressure.

Glitchtchtchitch is presented by running more than 10 Processing sketches at the same time, and using 2-3 projectors to increase the amount of screen, the variety, and increase the level of distortion.

 

Main idea –>  In order to cubify heads, instead of just altering pixels, I made an object “Cube” to get, restore, alter, and display the pixels of specific range. Also to achieve the headless effect, besides the library OpenCV, I took a background image beforehand, and display its pixels within certain ranges, once detecting a face. ALL THE SOURCE CODES

 

Notes

  • Speed issue has room for improvement.
  • Different scale presentation style(projectors included) looks nice.
  • From user test and presentation feedback, people love headless and delay effect the most. Because they’re the most bizarre, unrealistic, and uncommon visual impact.

Problems with solutions

  • OutOfBounds —> constrain(xxx, 0, numPixels-1)
  • flip horizontal —> video.width-fx-1
  • can’t cover image with pixels[ ] —> solved by using pixels for both
  • improve the sketch speed —> P2D, PFrame,
  • connect to webcam? PS eye? —> camera list, example

ICM_Faking multi-window display mode! (update)

black desktop!

black desktop!

(Update_11/25)

Find the way to move menu-hidden sketch window!

import java.awt.MouseInfo;

// do whatever you want

int mX;
int mY;

void mousePressed() {
  mX = mouseX;
  mY = mouseY;
}

void mouseDragged() {
  frame.setLocation(
  MouseInfo.getPointerInfo().getLocation().x-mX,
  MouseInfo.getPointerInfo().getLocation().y-mY);
}

————————————————————————————-

Found the Plan-Z to present my Glitchtchtchitch final– make my desktop all black and  hide the title bar of all my sketches!!! It’s a dumb way I know… but at least it works!

codes for Processing

public void init(){
  frame.removeNotify();
  frame.setUndecorated(true);
  frame.addNotify();
  super.init();
}

The only drawback is… I can’t move the sketch window after doing this! Which means I should run my sketches twice for each one, first time comment the magic codes out and adjust the location, then close it and bring the magic codes back, and then run it again…

Viva la vie.
