Evaluation

After working and researching in using processing over the past few months, I have gained a great amount of understanding of how it works. At the beginning of the unit I struggled, probably because I didn’t know what a lot of the code meant. I understood the basics but when it came to ‘for’ loops and ‘agents’ I was lost. It also hindered me in what I wanted to produce. I poster earlier in my blog that I was unsuccessful in creating what I wanted for my first idea. However, after some research I can up with my final idea and what I wanted to achieve with it, I feel I accomplished both of these. My steps for my final idea were:

1. Track and draw over any movement on the screen, that movement represents public performance
2. Anyone stood still on the screen is not drawn on, reflecting private performance
3. Those who aren’t drawn over will be encouraged to move/perform in order for their movement to be drawn, making them public

I managed to meet these steps and was successful in doing so. The installation works slightly different to how I imagined it, but obviously I am still new to the software so it is difficult to replicate exactly what you imagine. However, I still achieved what I had set out to do whilst exploring my chosen theory taken from Goffman’s ‘Presentation of Self in Everyday Life’. There were some other minor problems to do with lighting in the background but they did not largely effect the installation. What I could improve on would be dealing with how the lighting in the background effects the drawing of movement as well as other ways to draw and animate movement. I could try different patterns or even a completely new way of representing movement as a public performance. I would also try another test, but for a longer period of time. By extending the duration of the test more people will have passed by and stood at certain times in Weymouth house. Thus, there would be more chance of people interacting with the piece. If I was to test again but with this situation, I would not crowd around it with the rest of the group testing their installations as I found it drew a lot of people away because we appeared to be doing work in quite an open space people did not want to get in the way.

Final test

As i’ve said in my previous few posts, I encountered some problems with my installation. Those problems as I’ve said have now been solved and it works fluently with no glitches and with a better frame rate. As you can see in the video below the delay/fade effect created after a person has moved works well. When people are stood still they are not effected by movement drawing and those moving are. The person on the far left is an example of a minority that I mentioned about before in (People in the space), they are stood at the side because they believe they would be getting in the way. This is not the intention however, but the purpose of the installation it is not always obvious to every person walking by or maybe they want to remain in their own private performance.

Final test

Iteration 5 – Results of testing the installation

After testing some problems arose which were quite easily solved. One problem being that the outline was not very visible around people because they were far away from the camera. By simply increasing the stoke their outlines were more visible and actually made a better outcome than I expected. When I was testing the installation on my own at home it looked good but in a large area it work really well. I was asked about it by a person stood close and I explained to him what it was and what I wanted to achieve, he said it was “really cool and intriguing”.

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.

Iteration 3 – Continuing with movement drawing

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

My Idea coming together

Iteration 1 – Changing of ideas (Reversing what represents public and private performance)

After some time trying to fix the problems I encountered with face pixelation I have decided on a different idea, something that feels more artistic but still conceptualises the same theories. I have stopped work on the CCTV style both pixelation as seen in previous test posts and adding the time and date as seen in (CCTV style and CCTV style creation).

After a while of looking around the internet for examples I can gain inspiration from. I have come up with the idea of colourfully drawing the movement of people. It follows a similar idea to the previous with people who aren’t moving are untouched by the installation, but anyone moving on the screen will have the parts of them that are moving colourfully drawn over. In this way it encourages others (who are stood still) to join in and move too; becoming part of the collective group of people moving. In this way the installation has encouraged a large amount of public performance. Another reason I have decided to take a different approach with my design is because the more artistic and creative I can make it the more interesting and entertaining people will find it when they interact with it. The blurring of peoples faces seems too simple and could be argued to exist unnoticed. This is because the only real interaction the audience can do is show their face to the screen. With this new idea the audience can experiment and move around to see how the illumination will react.

Although the overall style and idea has changed the purpose of the installation still stands. My new idea still supports Goffman’s ‘Presentation of self’ and still encourages performance. I have also reversed who represents public and who represents private.

Those who are drawn over are public as they are moving or performing. Those who aren’t moving are private as they have no intention to perform on the screen. Those who aren’t drawn over will feel encouraged to perform in order to be drawn over. Thus, they become public.

An ambitious aim would be to make the outline that illuminates drop small pixels that fall to the bottom of the screen, like a gravity effect. Another idea would be that the illuminated outline of movement would stay on the screen after that person has moved on and then slowly fade away. Highlighting a transition from public to private performance.
