Testing in Public Space – Resolving Problems

20150114_145209Today, I tested my piece in the public space and had to overcome various problems in order to get my interactive piece to successfully work. I initially had planned to display my piece on the public screen opposite Costa (see image on right). I set it up using my laptop webcam, however as expected the crowded background in Weymouth House meant my piece wouldn’t work correctly. The video capture picked up the posters and various other objects which caused the shapes to not work correctly. I experimented with altering the threshold level in the code, but to resolve the problem I needed to put up a white screen to blank out the cluttered background. Here are the different threshold experiments, ranging from threshold of 70 – 140:

Due to circumstances I was unable to put up a white screen as Costa did not approve as it meant some of their seating would become obstruct20150121_111653ed. Therefore, I was unable to use my chosen public screen. To resolve problems with the cluttered background, I set up my piece in the small tv studio, near the entrance of Weymouth House. The walls were plain white and there was more space for users to interact with my piece. I used a portable screen, of which I connected my laptop to, and video captured users from my laptop webcam. However, due to the lighting of the area, I had issues with capturing a silhouette-like figure. As the lighting was shinning directly down and I was wearing a short sleeve top, it meant my arms appeared as being mainly white. This made it quite hard to interact wiScreen Shot 2015-01-21 at 11.47.51th as obstructing the falling shapes was more difficult. Also, due to their being a bright light shinning directly onto the area, it meant a shadow appeared on the white wall behind the person. To resolve the problems, I altered the lighting and experimented with various different threshold levels to see what worked best in the area. I also found that the piece seemed to work best when users had long sleeves on as this meant they appeared as being more silhouette-like. I decided to rotate the portable tv screen around, allowing the users to see themselves on the laptop screen and others to view the piece on the tv screen. This meant that even if people didn’t wish to interact, they can still view the piece and decode their own meanings and messages. Here are pictures of the final set-up and users interacting with my piece:Screen Shot 2015-01-21 at 14.57.15 20150121_120433

From this, I feel I should’ve possibly been a bit more organised and asked in advance about a white screen and permission from Costa. However, I feel that the area I used in the public space worked out to be more suitable, as it allows more room or individuals/multiple users to interact. Its also means that to preview the piece, you don’t have to physically interact with it as you can see others interacting on the public tv screen. I think that due to the area and set-up, when people see others interacting then it encourages them to go up and interact. Users can interact with friends and are able to have more fun playing around with the piece. Next, I will add videos of users interacting with my final piece and discuss comments that I recieved when displaying my piece.
