Public Interface Observation – Subway Turnstiles

I observed a some turnstiles where people swipe their Metrocard to enter the 4th Ave/9th Street subway station in the afternoon. This station is not as as high traffic as some stations in Manhattan, so people do not typically queue and crowd around the turnstiles. I think this is reflected in that there are not as many turnstiles, though I would assume that they are designed for efficiency, so people can get through as quickly as possible, and to be foolproof, to ensure fare is paid, without being too inconvenient to use.

ICM Week 3 – Part 1

The first part of this week’s assignment is to create a sketch of some kind of rollover, button, or slider interaction from scratch. In the second part, I will swap sketches with a classmate and make some changes to his/her code. I’ll add a link to that post later.

I decided to create a slider that would change colors. I wanted the user to drag his/her cursor so the colors would change like turning a page in a multicolor book. Full code is available here and this is the final version.

What Is Interaction?

Chris Crawford defines interaction as “a cyclic process in which two actors alternately listen, think, and speak” [1]. Bret Victor’s rant on the future of interaction design focuses on how humans might interact with tools by using our hands to interact them physically. I agree with Crawford’s idea about physical interaction being cyclical. Humans take the flow of information using our senses (listening), we process it in our brains (thinking), and then we react in some way (speaking). On the other hand a device would be doing the same process except by taking inputs from sensors, following programmed instructions, and then creating an output. This back and forth does make up the physical interaction between the two actors that Crawford talks about.
