I also visited some other designers how worked on digital design, including the designers from Dundee DJCAD (where I spent my final BA year). Then I saw Sarah's design- Data license, which is so similar to my idea (but in a different way). I also interviewed her about her project and found out that she just graduated form CSM ID. 2 experts in a day, bravo! I tried out her device and kept a copy as evidence. She told me I could find the white paper online. I think I would study on it after I got home.
Another thing worthy to be mentioned is that we tried on a very interesting installation (uniq coats from a cloak room), That was a very different experience for me. And I believe it is a very smart way of expressing ideas.
