Physical Interaction Exploration

It was a self-initiated project which I start with the motivation of learning more about physical computing, seeing how it would be to create both software and hardware which works together, and exploring what interaction with a machine/device could be beyond pushing buttons, touching screens, or waving to proximity sensors. My initial ambition was to create a responsive fabric material woven out of conductive rubber cord, a flexible material changes resistance when stretched. So everything would be more honest, and we would be interacting with the material itself. But that didn’t happen because I couldn’t get the material to work stable enough. So it ended up being waving to a proximity sensor again, but it was fun trying:D

Evrim Şahin, my beloved physical computing instructor from bachelors, was mentoring and helping me figure out things along the way.

It was a lot of trial and error in the process. Especially with the conductive rubber cord that I was planning to create a woven fabric surface. Although it didn’t work out for this project, it is a cool material check it out here if you are interested. I was also looking for a easy to use/ beginners tool to plan the circuit. Frizting is pretty nice for that.

Here are the components that I have used. Let me know if you want to recreate this project and I can share the Arduino code lying somewhere on my hard drive :D
