People in the space

There were many people walking through the space we tested in. Some people walked passed with noticing what was going on and what we were doing, obviously too busy performing to impress their friends. There were a minority that stood by the door and waiting as if we were taking photos and they did not want to get in the way, which was quite funny to see. There were others who were intrigued by what we were doing and actually interacted with the installations. I overheard one person in a group asking “shall we go over and see what it is?” but the rest of the group held back and did not want to draw attention to themselves. I a sense this also reflects on performance as that group wishes to remain in their private sector rather than publicly performing to the camera to see what it’s all about.

Iteration 3 – Colour Testing Problems

I have tried experimenting with different colours. I decided on black as I thought it would be more subtle. However, after testing the installation in a public space I decided that it wasn’t very effective. As you can see in the screen shot above the person moving in behind me is only blurred slightly and due their dark clothing there was not much of a visible effect. It’s only the person’s head that is distorted by the colour. This is not what I wanted to achieve and therefore black is not an effective colour. I will continue to experiment with other colours and note down their outcomes and decide whether they  are effective or not.

Iteration 3 – Colour Testing Problems

Iteration 3 – Colour Testing

Once I had finally achieve a delayed fading effect on movement I decided to explore with different colours and assess their outcomes. I tried both blue and black to see how well they would work. Blue stood out too much and looked to colourful for the purpose of the piece. Black is more subtle and after testing it a few more times proved that the drawn lines left behind after movement faded better. Blue seems glitchy and I wasn’t really visually pleasing for me. I will try some different variations of strokes and opacity and see what outcomes I get.

Iteration 3 – Continuing with movement drawing

I have progressed further in the overall style of my installation. Previously I only had a white outline of movement which was a only slight alteration from the original Open CV ‘find contours’ example. Now I have added my own ideas and other inspiration to the piece. I was able to achieve both movement outlining as well as changing faces, which is very similar to face pixelation which I posted previously and attempted to create. As you can see my torso is still but I have moved my face slightly. This is similar to what I wanted to achieve, the idea that people moving are drawn over and those who are unchanged. There are two ways audiences can perform with this. One is that they move around so that they can draw their movements so that they blend in and look like everyone else who is moving, who are paying attention to the screen or not. The other could be that a particular person is moving and then attempts to stay as still as possible.

fill(255,0);
rect(width,height,0,0);
for (Contour contour : opencv.findContours()) {
contour.draw();
stroke(255);
fill(255,20);
strokeWeight(2);
beginShape();
for (PVector point : contour.getPolygonApproximation().getPoints()) {
vertex(point.x, point.y);
}

As you can see at the top of this section of code I have a rectangle that fits the whole of the screen and it is set to transparent. This creates an alpha channel which is important for creating a delay effect on the contours. It allows the drawn contours to remain static after a person has moved. The drawn shapes then slowly fade away and return to the position of the person after they have moved. Before I had written this the contours disappeared as soon as the person had stop moving and didn’t look very interesting. Drawn shapes/lines would disappear immediately because there was nowhere for said shapes/lines to stay. With the transparent rectangle present the shapes could be drawn over the top instead of over the top of the video. I also set the fill to (255,20) so that people could still see themselves over the movement drawings. Before I added this anyone moving was filled with block colour and it did not look visually pleasing. This way has a more natural look and looks better overall.

My Idea coming together

After some playing around and adding code from other processing documents I have made in workshops and at home I was finally able to achieve one of my ideas I mentioned in a previous blog post. By adding a transparent rectangle that fits the whole screen and sits over the video. This alpha channel combined with a fill with slight opacity has allowed the drawn contours to remain static for a few seconds and then fade away. In the screen shot below you can see that I have moved my head and the sketch has drawn where the movement began and it stayed there after I had moved.

Hopefully after the christmas holidays I will be able to test this in Weymouth house to see how the installation works in a larger space with more people and a lot more movement. Through testing I will be able to see if there are any problems that will need to be fixed and also how people will react to it. Testing the installation is a very important step in finalising the design

Tracking movement in Processing

I have started experimenting different ways of tracking movement. In the screenshit below I have used “opencv.findContours” and then set the contours found to be drawn as white lines.

This is a really good first step for the project as objects moving are changed and static objects are unchanged. This can reflect the difference between public performance and private performance as people moving through out the space the video captures are outlined distorting their appearance, reflecting that they are performing. Whereas, those who are still are not outlined are not moving/performing and are therefore private.
