Interactivity:
Wednesday, November 14th, 2007We had a special guest, Dr. Paul Pangaro, who spoke at our Thursday session on the topic of Cybernetics: He spoke bbout intelligent design and loop(s) affected by the system in which it lives. He also discussed the goals of the system and how we interact with such a system, amongst many other things. So obviously our assignment was to design something Interactive.
What is interactivity?
There have been many articles written about Interactivity from a Wikipedia entry to the AMHOOVER PRESS description. And many more… There’s online interactivity, social interactivity, physical interactivity, object interactivity. It’s a buzz word in today’s modern world.
But what does interactivity mean to me? To me interactivity is the dialog between people and or objects where there’s MAY be an unpredictable result which could manifest itself either via a computational result, physical or emotional outcome.
So what was next? I needed to design something interactive. First thought was to create something with electronics. But that was an easy copout for this project fore I have created interactive objects for this class before. For example, my badly, esthetically designed energy project.
So my challenge was to choose a medium without electronics and to incorporate the cybernetics model. I looked around and thought about paper. It’s all around us, and with a little creativity we can make it into something other than a medium to print on. What will I make? I asked myself. I remembered making models when I was a kid with paper and have seen other complicated paper models on the web.
Some models include:

Those were a bit complicated, given I had to present this day. I then thought about combination locks. Combination locks required some thought and minor skill, along with patients. There my interactivity was covered. i looked at some websites for paper combination locks. not many out there but Flying Pigs website does have a downloadable example: http://www.flying-pig.co.uk/pagesv/combi.html
I wanted to have a lock different from a standard combination where you have to turn the key in specific sequences. I sketched out a few designs and then started cutting. Here’s what I came up with?





There are 6 squares with a key path cut out in different directions. The key has 5 protruding points equally spaced. The key here, no pun intended, is to space the squares effectively so that the key can go in and out without totally locking up the system. So this design was quite simple and the use of foam core - instead of paper, and push pins aloud for effective prototyping.
The next step was to seal conceal the view of the squares and have a user test.
In class some had trouble getting the key out and others made it with ease. I would have liked some design feedback but that was not the point of the class.
Going through my checklist here’s what I covered:
SYSTEM: Combination lock
GOAL: Getting the key in and/ out of the system
ACTION: Turning key right or left and pulling
SENSING: When you hit a square you know you have to turn and feel for the gaps
DIALOG: what happens if you it’s too easy or two hard for the user.
As for the LOOP, I am not sure if I got this port in my model. Turning the key, push or pulling the key back and forth maybe part of the loop, but the system is not intelligent. It’s very passive. A more complex version would be to have a paper combination lock which randomly rests itself each-time the key escapes. I may try that in the future but for now I will attempt to build one out of wood employing a slightly more complexed system. I did accomplish my goals of making something interactive without electronics which provoked an emotional response.

Look forward to future blogs about my models.
