The context for this piece was to create something that would have engagement and appeal to someone who would use it. Ultimately I wanted to try to create a “machine” that could in some way provoke a reaction, an emotion or a need to use it again for that hit.
This lyric from The Verve seemed to capture the thought perfectly;
Imagine the future Woke up with a scream I was buying some feelings From a feeling machine” – The Verve
Looking at the way I experience the compelling nature of artworks I wanted to create that experience for others. The Secret Deposit Box was the final concept, where the users would provide the content that allows others an emotional response when they interact. In a way, it is completely about two people who are connected through sharing their secret. It is anonymous yet at the same time a very connected experience.
The human connection is the primary goal, and reading through Interaction Design, the user-centered approach is key; finding a way for engagement, appeal and touch. I decided to focus on secrets after seeing a few different sources including a compelling series of photographs by Simon Jessop that was in The Guardian every Saturday for a period of eighteen months.
1 Simon Jessop is a photographer who was commissioned to take photographs of strangers holding a blackboard with their handwritten secret on it, in front of their face to avoid detection. It proved to be a very popular and engaging series that can be seen on his site.
The art world has a way of making us think and feel in response to experiencing an artwork. This is what I want to achieve, so I spent time remembering artworks that had a profound effect on me in some way, or that I made an emotional connection.
The photographs do not do these works of art justice, and I was mesmerised when I saw them in person.

In addition to Jessops photos, Gillian Wearing created works dealing with confessions. The people confessing were disguised wearing comic masks in addition to a series of videos called “Secrets and Lies”.
In 2009, Wearing’s “Secrets and Lies” still image from the video. Another video piece was of people who had responded to an advertisement that was placed in Time Out Magazine asking for people to ‘Confess all on video’. Many replied and confessed to a variety of things they felt they had done wrong or a particular vice they had.

The idea of sharing a secret seems alluring to many people. Both the sharing and then reading another’s secret are compelling to us. This online project which is also an app Post Secret http://www.postsecret.com/ lets people send in their secret on a postcard.

There are 3 steps the user will take.
Step 1 is to write their secret
Early prototypes had an Arduino controller with an OLED display which will be initially visible to the participant, but the buttons will remain under a discreet panel so they are out of the way but as I found myself explaining the project and how the machine worked I would often omit that aspect. This led to me not including it in the final piece and keeping this initial process very straightforward.
Step 2 involves them scanning this secret they have written.
This will also trigger some LEDs that are super bright so they know there has been a photo taken. A sound will also be activated. Looking at web cam tools as a means of capturing a bitmap version of their scanned secrets.
Step 3 They then scrunch up the paper and deposit it into the Secret Deposit Box. There is also a secret printed out for them, which they tear off.
The main hardware used for the final piece was a mini thermal printer, a web cam, an Arduino Uno board and a large arcade style button. There were other additions to the project but those are the core items. The other things were blue LEDs that ran separately on a teensy board, some RGB lights to light up the area where people were to deposit the secrets and there was an LCD monitor initially that after making paper prototypes I realized that this was an extra step of complication that didn’t really have a lot of benefit for the user.

I was lucky enough to have a friend draw up some 3D images for the construction of the box.
The outcome of constructing this product will take the form of a plinth, very much like a typical plinth you might see in an art gallery but with an angled top. The top surface will have detailed areas, listing the steps mentioned earlier. There will be a box area as the receptacle for the paper and a groove for the pencil. I anticipate the largest area will be occupied by the paper / scanning area. There will be space on the plinth to write the secret as well so the top isn’t totally taken up. It will also have a clear area to the plinth so that they can physically see the previous secrets that have been put in the plinth. I hope to have a very engaging and perhaps mysterious plinth that will engage people who take the time to explore it.
The construction of this project was done in several stages. There were periods of design and evolution that was done during a code-testing phase. I went about the construction of the project by testing separate pieces of code one by one and getting individual pieces to the work together. For example, I hooked up the button and ran the simple code to ensure the button was working, once the button was error free I would then integrate it with the more complex code, testing as I went.
For the plinth construction, Redboat Creative designed the plinth models in 3D once we had had several consultations about what I needed from the plinth. He gave me several interactions of the design as certain components and sizes changed. These drawings are included in the appendix. Unfortunately, I had to build the box myself so there were a few issues with it and it wasn’t constructed to plan but it is very sturdy and did the purpose it was intended for.
Some issues I encountered were that initially there was also a screen to serve as a prompt for someone to know what to write, but as I found myself explaining the project I kept omitting that detail due to it becoming confused for them. When explaining the project I kept it simple in terms of saying it was 4 main sections, Secret (where you write yours down), Scan (where the secret is captured), Scrunch (where you get rid of your secret) and Save (a print of someone else’s secret). The flow of that seemed really tight and so when I came to do the prototype I decided to stick with that and make it very streamlined.
Code issues were things like, once I had the Arduino communicating with the mac, and taking an image, although I had an image on the screen as it should be, it was saving a black photo. I was using:
when I realized that the issue would be that I am not telling it explicitly what to save, so I modified it to:
which solved that issue. Also, the image format for the thermal printer has to be in 1 bit bmp format. I initially tried tests with taking the image and exporting it through Photoshop which was not working as the lowest amount of bits I could bring it down to was 4. The advice through the forums all were for PC systems, not mac.
I eventually used Automator to create a workflow on the data folder where the images were being saved. My eventual workflow at this stage was scale images, to be sure they were the correct size, to applying the ColorSync profiles to make it Black & white, and finally save it as a .bmp file.
The other issue was creating the file that would contain the data required by the thermal printer. This resulted in extra processing code that is used to write it to the correct sequence of data. The code is in the Appendix as the image to byte array code.
When the box was presented it was interesting to observe people using it. The instructions were clear for some but for others, they seemed to want to use it to get to the end result as fast as possible. Meaning they skimmed the instructions, which I thought had been minimal anyway, and so usually at the scanning (step 2) a few people were so excited to get the secret out of the box that they forgot to remove their secret from it to scrunch it up and deposit it.
I was on hand to tell them but I see that as a failure of the system in terms of them receiving the secret and that being viewed of the final step (which ultimately it is).
The work was a success in terms of the compelling nature the box seemed to have. I had people asking me if they could put in more than one secret, which of course they can, and that was great. The reactions of people reading the secrets and wanting more was fantastic. Some people chose to share the secrets they got with others but many reacted and then kept them. Several days after the event was finished I went back to read the secrets written on the paper and the effect of reading them was actually a lot more powerful than reading on the slip of thermal paper that gets printed. This made me think again of the box in terms of what it does for the viewer and I would actually love to do another version where the secrets are written on paper, and put into a big area similar to a bingo machine or lottery machine, and when you put in your secret, you watch the machine spin the secrets and then it will give you the actual paper secret that someone else had written.
Also on the day of the presentation when I set up the box, the code wasn’t working as I had intended and I wasn’t sure why so I had to amend the code to basically have it function on a basic level, which it did and it didn’t ultimately change the work other than I knew it didn’t have the same code on it that I had intended. In the Appendix is the code as was initially intended and then the code that ended up running on the day.
Due to the fact that the box construction took a lot of time including trips to the hardware shop for supplies that I felt my code and assembly time was reduced and I hadn’t planned for that. If I had to do this again I think I would start with the construction of the housing, even though this is risky itself as the design had changed at a few different iterations. Even so, I would have loved to have built my electronic components in-situ and to have a lot more time perfecting the code.
I think I would have also liked to have more time to be able to test it as an item with people like on the exhibition day because a few issues surfaced then that I didn’t have time to clear up. It did seem once people had the initial instructions it was very easy to grasp, and there were even people telling others how it worked so clearly it was easy to understand, however with many people not actually reading the instructions I could possibly alter that.
This could take the form as an initial design had, where each section was in a “box” or outline so they had to acknowledge that it was a process. Also, some people found the flap for the secrets confusing in terms of which side to lift, or to slide the secret inside somehow. As well the scanning area, designed in the end to be like a punch card design I think was confusing for some and they had to be told to be sure to remove their secret paper. I had wanted to have a shredder system but at that point, it had already become so complex that I had to decide to stop the project at a certain point. This would perhaps be an interesting idea to revisit with the shredder to actually then destroy their secrets.
Overall the piece was a success due to the reactions of the people using it and seeing the nature of them wanting more made me satisfied that this was effectively the feelings machine that I sought to make initially.
