Wheelies
Every now and again, an invention comes along that is so good, so elegant and so universally useful, it is hard to imagine life without it. Yet there was a day before—about 6,000 years ago—when there was no wheel. Then, of course, the day came. And all across the Neolithic world, people who saw a wheel for the first time grunted, "Yeah, that's better," and started making them.The future on a roll.
Tech is about insight. It goes beyond the "aha" of understanding how things work to the spark and sparkle of seeing how else they might work. A sense of play and humor help, liberating box-bound "what is" thinking for a considerably more fun, imagination-fueled "what might be" point of view (see Montessori and Maker Faires). The wheel? If not from the mind of a child, then clearly from the mind of someone in close touch with his / her inner child (which might not have been that difficult given a Neoltithic life expectancy of about 20 years).
Tech is also about connection. Inventions just don't survive long in isolation. Not only is it a matter of sharing ideas, but of mixing and matching them to in ways that lead to the new discoveries. "Iteration" is just "tech-speak" for evolution. Grow, change, develop, adapt...lather, rinse, repeat.
Which is a round-about way of sharing our favorite new wheel here at TrackerNews: InSTEDD's Reporting Wheel (disclosure: the TrackerNews project was incubated at InSTEDD).
Described as "IT without software," the wheel—actually three circular pieces of cardboard or plastic with a grommet in the center—was developed to help health workers in Southeast Asia more accurately report data.
Although the InSTEDD team (special hat tip to Nico di Tada and Eduardo Jezierski) had developed some pretty nifty software called Geochat for SMS reporting, and done their homework in the field to come up with a syntax to codify disease reporting, the logistics of texting turned out to be a deal-breaking stumbling block. In the rural areas of Cambodia and Thailand:
- Most people do not know how to send SMS.
- Some of them do not know how to read an incoming SMS.
- Support for Khmer and Thai characters is not common in the handsets and carriers most people use.
- Even if there is support for the characters, writing SMS using them is much more difficult than writing in English due to the amount of letters in the alphabet.
These posed a huge barrier to solve even before the reports could be collected.
This wasn't only a setback for local public health, but also for global health efforts. The region is often among the first to see the emergence of new, deadly strains of influenza. Early reporting can mean the difference between a contained local outbreak and a global pandemic.
The answer wasn't to be found adding more bits, bytes or bandwidth, but in understanding that the the bits, byte and bandwidth were about "channel," not reporting.
What if we decouple the process of structuring the report from the channel through it was sent? If you ask someone to send a telegraph, he does not need to know Morse code. In the same way, we could allow health workers to create the report outside the constraints of the tool being used to transmit it.
Brilliant. Each of the wheel's three levels focus on a different question: for example, date, disease and number of cases. The wheel itself is printed so that as answers are slotted in, they correspond to error-proof three-digit codes printed on the outer rim.
The codes for each reported value are selected in a way that not only allow the dectection of errrors in the typing, but also enables the detection of the kind of wheel used to report. With the method we developed, a total of more than 600k different wheels can be created and each can be uniquely identified with no additional information—only the 9-digit number reported is required. That means the same reporting hotline can be used to receive report from a wide variety of sources.
The wheel: 6,000 years and still astonishing.
