I just read a great article on interfaces by Baobab's Mike McKay entitled Text Editors and Electric Kettles. It's really worth a read. It's the kind of thing I'd show to design students, it's so good. And it also does a nice job summing up some of the challenges and solutions that they're working with specifically down in Malawi. And, hey, if you have a digg account, bump the story up!
A great amount of work got done thanks to the help of everyone here. Below is the latest prototype. It's printed on paper, but another version is making the rounds that was printed on indestructible HP LaserJet tough paper, a kind of polyester film available in consumer sizes.
I was also able to get the ART system up and running for the AIDS clinics. Based on the observations we made earlier in the week, I was able to hack into the Ruby on Rails app and get it to work along with the bar-code scanner. Now MUAC data goes straight into the database--a full prototype system, working end to end! Sweet! And it works pretty much as expected (minus bar-code reader) on my touchscreen Nokia internet tablet.
So, next week is testing and observations. That should give me ample time to make adjustments before heading back to the states.
