Testing in Public Space

Here are the some videos of users interacting with my piece in the public space:

I feel that these show that my piece was successful in the public space as all users were easily able to interact with the piece without difficulty and they understood that they could use their body to obstruct the surreal falling shapes. I think that users enjoyed interacting with my piece and found it quite fun. The fact that multiple users can interact at once was good as it meant those that were more shy to interact could join others rather the interacting singularly. Also, those that didn’t wish to participate themselves were still able to see the piece. At the time of displaying my piece, the public space was fairly busy meaning I was able to get a fair few people to interact and many who watched the tv screen to see what was going on.

Barthes (1964 p.148) believes that

‘the birth of the reader must be at the cost of the death of the author’.

I feel that this can apply to my piece, as the power is given purely to the users. They are able to interact in any way they want, and without direction from me (author/producer), the users (readers) were able to understand my piece and seemed to enjoy interacting with it. It is the users that then appear on the tv screen of which passers by can see, meaning that they actually become a part of my piece. As mentioned in a previous post, Gray (2010 p.166) also suggests that

‘a text only becomes a text, only gains social meaning and relevance, at the point that it comes alive with its audience.’

This highlights how in order for a text to be successful then it needs to have an audience. I feel that my target audience seemed to enjoy interacting with my piece and users had fun obstructing the falling shapes in various ways. Some viewed the piece on the portable tv screen and asked questions, showing that they were interested and intrigued with the piece but maybe were too embarrassed to interact in front of others.

Overall, I am pleased with the end result and feel that my piece worked well within the public space. Next, I will go on to briefly evaluate my piece in relation to the brief, and discuss the iterative processes that I followed.

Processing Workshop – Video

In todays workshop, we learnt how to set up basic video capturing. This is useful to me as I need to understand this for my piece. The video capture setup is quite basic but you can add additional code to set it so that if the camera doesn’t work, an image will load instead, which could be useful for my piece. In the workshop, I set up the video capture and set it so if its bright, the sketch goes white and if it is dim the sketch goes black. Here is the code:

Overall, learning the basics of video capturing in this workshop was useful to me and from this, I will go on to advance my knowledge to learn more about motion and brightness thresholding, of which I will be using for my interactive piece.

Processing – Experimenting with Video

I have been looking at some processing video examples that I find interesting in order to help me develop ideas for my interactive piece. I have also been watching some of Daniel Shiffmans’ processing tutorials in order to improve my understanding of past processing skills that I have learnt as well as develop new skills. I have learnt more about the Capture class, and the steps required to setup video capturing. I am going to analyse some video capturing examples, and explore how I could make it interactive within public spaces.

  • Video Pixelation – Likewise to images, you can also get the pixels of a video capture. Similarly, you have to use for loops and the pixel array formula (x+(y*width)) but in this case you load the video capture rather than an image. An idea relating to video pixelation could be that if people are moving at a certain speed, they will become pixelated, whereas if they are stood still in the space they become in focus.
  • Motion Detection – This is something I would like to incorporate into my interactive piece, but I need to be aware that at busy periods, there will be lots of movement within the public space. An idea related to motion is that when someone walks into the pubic space a new class/object will be created, which then follows the fastest movement within the public space (motion tracking).
  • Colour Tracking – Instead of tracking motion within the space, I could set it so the camera tracks a certain colour. For example, when someone walks past wearing red, an object could follow them on the public screen. However, this would become complex if there was lots of people wearing the same colours.

From looking at these examples, it has helped me to improve my processing knowledge about video capturing and motion detection/tracking. From this, I would like to incorporate motion in order to make my piece interactive, but still need to continue to fully develop an idea. To do this, I am next going to look at some existing interactive pieces that I find interesting.
